Description

Pressure-resistant motor

This application is a divisional application with application date of January 20, 2020, application number: 202010065072.X, and name: "Pressure-resistant motor".

Technical Field

The invention relates to a motor structure, and in particular to a pressure-resistant motor.

Background Art

If it is desired to perform disturbance in the pressure vessel, such as stirring and mixing, a fan blade is usually installed in the pressure vessel. The motor driving the fan blade can be installed outside the pressure vessel, as shown in FIG1 , where the fan blade F is installed inside the pressure vessel T, the rotating shaft A of the fan blade F extends to the outside of the pressure vessel T, the motor M is installed on the outer wall of the pressure vessel T, and the motor M is covered by the outer cover C. In addition, the motor driving the fan blade can also be installed inside the pressure vessel, as shown in FIG2 , where the fan blade F is installed inside the pressure vessel T, and the motor M driving the fan blade F is also installed inside the pressure vessel T.

In the structure of FIG1 , since the rotating shaft A of the motor M must extend from the outside of the pressure container T into the inside of the pressure container T, an opening must be formed on the wall of the pressure container T for the rotating shaft A to pass through. This opening structure easily causes leakage of the pressure container T, so the motor M is covered with an outer cover C in an attempt to reduce the leakage problem. However, the outer cover C causes the problem that the motor M cannot dissipate heat, causing the motor M to be easily damaged.

In the structure of FIG. 2 , since the motor M is directly installed in the pressure vessel T, although the leakage problem can be avoided, the heat dissipation problem of the motor M cannot be solved. Moreover, the fluid in the pressure vessel T may damage the circuit structure of the motor such as the coil.

No matter in the structure of FIG. 1 or FIG. 2 , there is no standard for the thickness of each part of the motor M and the pressure vessel T, which results in excessive waste of materials or insufficient thickness resulting in damage to the barrel by fluid pressure.

DETAILED DESCRIPTION

Please refer to FIG. 3, FIG. 4, FIG. 5A and FIG. 5B, which show an embodiment of the pressure-resistant motor of the present invention. The pressure-resistant motor 100 of the present invention can be installed outside a pressure container T (as shown in FIG. 8A). The pressure-resistant motor 100 of the present invention includes a sealed housing 10, a first seal 20, a stator assembly 30, a rotor assembly 40 and a rotating shaft 50. The "pressure-resistant" in the aforementioned pressure-resistant motor means that it can withstand an absolute pressure greater than 1kgf/ ^cm2 or less than 1kgf/ ^cm2 . The structure of each component and the mutual connection relationship are described below.

Please refer to FIG. 8B , the sealing housing 10 has a first joint surface 11, and the sealing housing 10 is joined to a wall surface T1 of the pressure vessel T via the first joint surface 11, and the first joint surface 11 corresponds to an opening O of the pressure vessel T. In this embodiment, the sealing housing 10 is cylindrical, and the first joint surface 11 is the axial end surface of the sealing housing 10. The first sealing member 20 is disposed on the first joint surface 11 and forms a sealing joint between the first joint surface 11 and the wall surface T1. In this embodiment, the first sealing member 20 is an O-ring, and an annular groove (not numbered in the figure) is formed on the first joint surface 11. The first sealing member 20 is embedded in the annular groove. The sealing housing 10 can be combined with the wall surface T1 of the pressure vessel T by using a coupling member (not shown in the figure), so that the first joint surface 11 is pressed against the wall surface T1 of the pressure vessel T, and the first sealing member 20 is pressed between the first joint surface 11 and the wall surface T1 to achieve a sealing effect. It is particularly noted that the coupling member may be a screw, a bolt, a quick clamp, a fixture or a welded member. In other words, the coupling member may be formed by welding.

The stator assembly 30 and the rotor assembly 40 are installed in the sealed housing 10, and the rotor assembly 40 rotates by interacting with the stator assembly 30 to generate electromagnetic force. In this embodiment, the stator assembly 30 can be a coil, and the rotor assembly 40 can be a magnet. The current passes through the coil of the stator assembly 30 to generate excitation to rotate the magnet of the rotor assembly 40.

The rotating shaft 50 is coupled to the rotor assembly 40 and extends from the sealed housing 10 through the coupling surface and enters the pressure vessel T through the opening O. The rotating shaft 50 can be coupled to the fan blades F. The rotating shaft 50 rotates to rotate the fan blades F, which is used to generate disturbances in the pressure vessel T, such as stirring or mixing the substances in the pressure vessel T. The pressure-resistant motor 100 of the present invention further includes a first bearing 51 and a second bearing 52. The rotating shaft 50 is rotatably supported by the first bearing 51 and the second bearing 52. The first bearing 51 and the second bearing 52 are fixedly disposed in the sealed housing 10.

In addition, as shown in FIG. 4 and FIG. 5A, further, the sealed housing 10 includes a main body 12 and a flange cover 13. The main body 12 is cylindrical, one end of which is closed and the other end has an opening 121. The flange cover 13 is coupled to the main body 12 by a coupling member (not shown) and covers the above-mentioned opening 121. The flange cover 13 is a cover body, such as a circular cover body, a square cover body or a polygonal cover body. The flange cover 13 forms ends 131 and 132 at its two axial ends. In addition, a through hole is formed in the center of the flange cover 13 for the shaft 50 to extend through, and the above-mentioned first joint surface 11 is the axial end surface of the end 131. Of course, through holes (not shown) may be formed along the periphery of the two end portions 131, 132 for passing bolts (not shown) so as to couple the body 12 to the end portion 132 of the flange cover 13, and also couple the end portion 131 of the flange cover 13 to the pressure vessel T, thereby coupling the body 12 to the pressure vessel T.

The body 12 includes a second joint surface 14. The pressure-resistant motor 100 of the present invention further includes a second seal 60. The second seal 60 is disposed on the second joint surface 14. The flange cover 13 is coupled to the second joint surface 14 by a coupling member (not shown). The body 12 forms a sealed joint with the flange cover 13 at the second joint surface 14 by the second seal 60. In this embodiment, the second seal 60 is an O-ring, and an annular groove (not numbered) is formed on the second joint surface 14. The second seal 60 is embedded in the annular groove. In addition, of course, it is also possible to form a plurality of screw holes (not shown) on the second joint surface 14, so that bolts (not shown) pass through the through holes of the end 132 of the flange cover 13 and are screwed into the screw holes of the second joint surface 14 to lock the flange cover 13 to the second joint surface 14 of the body 12. It is particularly noted that the second joint surface 14 may include an inner recess (not shown), and the edge of the inner recess is configured to match the edge of the end 132.

In addition, as shown in FIG. 4 and FIG. 5A, further, the body 12 includes a barrel 122 and a rear cover 123. The barrel 122 is cylindrical, and its two axial ends are respectively a second joint surface 14 and a third joint surface 15. The pressure-resistant motor 100 of the present invention further includes a third sealing member 70. The third sealing member 70 is arranged on the third joint surface 15. The rear cover 123 is connected to the third joint surface 15 by a coupling member (not shown in the figure, such as a bolt). The barrel 122 forms a sealing joint with the rear cover 123 at the third joint surface 15 by the third sealing member 70. In this embodiment, the third sealing member 70 is an O-ring, and an annular groove (not numbered in the figure) is formed on the third joint surface 15. The third sealing member 70 is embedded in the annular groove. Screw holes (not numbered in the figure) are arranged along the circumferential direction of the third joint surface 15, and through holes (not numbered in the figure) are arranged along the circumferential direction of the rear cover 123. Bolts pass through the through holes and are screwed into the screw holes of the third joint surface 15, thereby fixing the rear cover 123 to the barrel 122. In addition, the first bearing 51 is arranged on the flange cover 13, and the second bearing 52 is arranged on the rear cover 123. As shown in FIG5A, a recess is formed in the center of the flange cover 13 to accommodate the first bearing 51, and a recess is also formed in the center of the rear cover 123 to accommodate the second bearing 52.

The pressure-resistant motor 100 of the present invention further includes at least one first outlet box 80. The sealed housing 10 includes a first opening 16. The first outlet box 80 is arranged corresponding to the first opening 16 and forms a sealed joint with the outer wall of the sealed housing 10. At least one cable S extends to the first outlet box 80 through the first opening 16. A sealing member 82 is provided on the joint surface 81 of the first outlet box 80. In this embodiment, the sealing member 82 is an O-ring. The first outlet box 80 forms a sealed joint with the outer wall of the sealed housing 10 through the sealing member 82. Since the first outlet box 80 is connected to the sealed housing 10 through the first opening 16, the first outlet box 80 and the outer wall of the sealed housing 10 must form a seal to prevent leakage of the sealed housing 10.

5B, 6 and 7, the first outlet box 80 includes at least one sealing joint 83, and the cable S extends to the outside of the first outlet box 80 through the sealing joint 83. The sealing joint 83 includes a fixing member 831, a fastener 832 and a locking member 833. The fixing member 831 forms a sealing joint with the first outlet box 80, the fastener 832 is limited by the fixing member 831 to fasten the cable S, and the locking member 833 is movably disposed on the fixing member 831 and positions the fastener 832 on the fixing member 831. In this embodiment, the fixing member 831 is tubular and includes an upper threaded portion 8311, a lower threaded portion 8312 and an abutting portion 8313. The upper threaded portion 8311 and the lower threaded portion 8312 are respectively connected to the upper and lower surfaces of the abutting portion 8313. The lower threaded portion 8312 is screwed to the first outlet box 80, and the abutting portion 8313 forms a sealed joint with the first outlet box 80 via a sealing ring 834. The fastener 832 is cylindrical and has at least one axially extending spring piece 8321 formed at an axial end edge, preferably a plurality of axially extending spring pieces 8321. The cable S is inserted into a sleeve 835, the sleeve 835 is sleeved in the fastener 832, and the fastener 832 is sleeved in the fixing member 831. The spring piece 8321 of the fastener 832 is clamped on the annular groove (not shown) of the sleeve 835 by the inner tube wall of the fixing member 831, thereby positioning the sleeve 835 and further positioning the cable S. The locking member 833 is screwed into the upper threaded portion 8311 of the fixing member 831, and the top of the locking member 833 can push the axial end edge of the sleeve 835, so that the sleeve 835 and the fastener 832 move in the fixing member 831, thereby constraining the fastener 832 by the inner tube wall of the fixing member 831.

Please refer to FIG. 8A and FIG. 8B . In the present embodiment, the first joint surface 11 of the flange cover 13 includes a first recessed portion 111 . The edge of the first recessed portion 111 is configured to fit the edge of the opening O of the pressure container T.

Please refer to Fig. 8C, which shows another embodiment of the pressure-resistant motor and pressure vessel combination structure of the present invention. In this embodiment, the wall surface T1 of the pressure vessel T includes a second recessed portion T2, and the edge of the flange cover 13 is configured to match the edge of the second recessed portion T2.

Please refer to FIG. 8D , which shows another embodiment of the pressure-resistant motor and pressure vessel combination structure of the present invention. The pressure-resistant motor 100 of the present invention further includes a pressure vessel flange cover 110 and a fourth sealing member 120. The pressure vessel flange cover 110 is disposed between the flange cover 13 and the pressure vessel T, and the flange cover 13 is coupled to the pressure vessel T via the pressure vessel flange cover 110. The pressure vessel flange cover 110 includes a fourth joint surface 112, and the fourth sealing member 120 is disposed on the fourth joint surface 112. The first joint surface 11 of the flange cover 13 is sealed with the pressure vessel flange cover 110 by means of the first sealing member 20. The pressure vessel flange cover 110 is sealed with the wall surface T1 of the pressure vessel T by means of the fourth joint surface 112 by means of the fourth sealing member 120. In addition, in this embodiment, the pressure-resistant motor 100 is arranged above the pressure vessel T, the opening O of the pressure vessel T is formed on the wall surface T1 of the top of the pressure vessel T, and the rotating shaft 50 extends downward from the sealed shell 10 into the pressure vessel T, so the extension direction of the rotating shaft 50 is the same as the direction of gravity. The structure of this embodiment is suitable for containing gas or liquid in the pressure vessel T. It is particularly noted that in the embodiment of Figure 8D, the flange cover 13 may not be used. In this case, the first joint surface 11 of the sealed shell 10 is sealed with the pressure vessel flange cover 110 by the first sealing member 20, and the pressure vessel flange cover 110 is sealed with the wall surface T1 of the pressure vessel T by the fourth joint surface 112 by the fourth sealing member 120. Among them, the second joint surface 14 may include an inner concave portion (not shown in the figure), and the edge of the inner concave portion is configured to match the edge of the pressure vessel flange cover 110.

Please refer to FIG. 8E, which shows another embodiment of the combined structure of the pressure-resistant motor and the pressure vessel of the present invention. The structure of this embodiment is partially the same as the structure of the embodiment shown in FIG. 8D, so the same elements are given the same symbols and their descriptions are omitted. The difference between this embodiment and the embodiment shown in FIG. 8D is that the wall surface T1 of the pressure vessel T of this embodiment includes a second recessed portion T2, and the edge of the pressure vessel flange cover 110 is configured to match the edge of the second recessed portion T2 and is engaged in the second recessed portion T2.

Please refer to FIG. 8F, which shows another embodiment of the combined structure of the pressure-resistant motor and the pressure vessel of the present invention. The structure of this embodiment is partially the same as the structure of the embodiment shown in FIG. 8D, so the same elements are given the same symbols and their descriptions are omitted. The difference between this embodiment and the embodiment shown in FIG. 8D is that the pressure-resistant motor 100 of this embodiment is arranged on the side wall T1' of the pressure vessel T, and the rotating shaft 50 extends downward from the sealed shell 10 into the pressure vessel T, so the extension direction of the rotating shaft 50 is orthogonal to the direction of gravity. The structure of this embodiment is more suitable for the case where the pressure vessel T contains gas.

The embodiments shown in Fig. 9A and Fig. 9B described later are embodiments in which the inner diameter R2 of the sealed housing 10 is different from the inner diameter R1 of the pressure vessel T. Fig. 9A shows that the inner diameter R1 of the pressure vessel T is larger than the inner diameter R2 of the sealed housing 10 of the pressure-resistant motor 100, and Fig. 9B shows that the inner diameter R1 of the pressure vessel T is smaller than the inner diameter R2 of the sealed housing 10 of the pressure-resistant motor 100. The inner diameter is the inner radius.

Please refer to the embodiment shown in FIG. 9A . In this embodiment, the pressure vessel T has a pressure vessel body T3 and two pressure vessel end plates T4 respectively connected to both ends of the pressure vessel body T3 and covering both ends of the pressure vessel body T3. The pressure vessel inner diameter R1 of the pressure vessel T is larger than the sealing shell inner diameter R2 of the sealing shell 10 of the pressure-resistant motor 100. Therefore, the sealing shell body wall thickness tc of the body 122 of the sealing shell 10 is smaller than the pressure vessel body wall thickness Tc of the pressure vessel body T3 of the pressure vessel T, and the rear cover plate thickness te of the rear cover 123 of the sealing shell 10 is smaller than the pressure vessel end plate plate thickness Te of the pressure vessel end plate T4 of the pressure vessel T. The rear cover plate thickness te of the rear cover 123 of the sealing shell 10 is larger than the sealing shell body wall thickness tc of the body 122 of the sealing shell 10, and the pressure vessel end plate plate thickness Te of the pressure vessel end plate T4 of the pressure vessel T is larger than the pressure vessel body wall thickness Tc of the pressure vessel body T3 of the pressure vessel T. The aforementioned sealing shell body wall thickness tc, pressure vessel body wall thickness Tc, rear cover plate thickness te and pressure vessel end plate thickness Te all refer to thickness.

In other words, in Figure 9A, the sealing shell inner diameter R2 of the sealing shell 10 is smaller than the pressure vessel inner diameter R1 of the pressure vessel T, the barrel thickness of the sealing shell 10 (that is, the sealing shell barrel wall thickness tc of the barrel 122) is smaller than the barrel thickness of the pressure vessel T (that is, the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3), and the end plate thickness of the sealing shell 10 (that is, the back cover plate thickness te of the back cover 123) is smaller than the end plate thickness of the pressure vessel T (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4), the barrel thickness of the sealing shell 10 (that is, the sealing shell barrel wall thickness tc of the barrel 122) is smaller than the end plate thickness of the sealing shell 10 (that is, the back cover plate thickness te of the back cover 123), and the barrel thickness of the pressure vessel T (that is, the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3) is smaller than the end plate thickness of the pressure vessel T (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4).

Please refer to the embodiment shown in FIG. 9B . In this embodiment, the pressure vessel inner diameter R1 of the pressure vessel T is smaller than the sealing shell inner diameter R2 of the sealing shell 10 of the pressure-resistant motor 100. Therefore, the sealing shell barrel wall thickness tc of the barrel 122 of the sealing shell 10 is greater than the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3 of the pressure vessel T, and the rear cover plate thickness te of the rear cover 123 of the sealing shell 10 is greater than the pressure vessel end plate plate thickness Te of the pressure vessel end plate T4 of the pressure vessel T. The rear cover plate thickness te of the rear cover 123 of the sealing shell 10 is greater than the sealing shell barrel wall thickness tc of the barrel 122 of the sealing shell 10, and the pressure vessel end plate plate thickness Te of the pressure vessel end plate T4 of the pressure vessel T is greater than the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3 of the pressure vessel T.

In other words, in Figure 9B, the sealing shell inner diameter R2 of the sealing shell 10 is greater than the pressure vessel inner diameter R1 of the pressure vessel T, the barrel thickness of the sealing shell 10 (that is, the sealing shell barrel wall thickness tc of the barrel 122) is greater than the barrel thickness of the pressure vessel T (that is, the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3), and the end plate thickness of the sealing shell 10 (that is, the back cover plate thickness te of the back cover 123) is greater than the end plate thickness of the pressure vessel T (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4), the barrel thickness of the sealing shell 10 (that is, the sealing shell barrel wall thickness tc of the barrel 122) is less than the end plate thickness of the sealing shell 10 (that is, the back cover plate thickness te of the back cover 123), and the barrel thickness of the pressure vessel T (that is, the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3) is less than the end plate thickness of the pressure vessel T (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4).

In summary, according to the embodiments shown in FIG. 9A and FIG. 9B , in other words, the sealing shell inner diameter R2 of the sealing shell 10 is different from the pressure vessel inner diameter R1 of the pressure vessel T, the barrel thickness of the sealing shell 10 (that is, the sealing shell barrel wall thickness tc of the barrel 122) is different from the barrel thickness of the pressure vessel T (that is, the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3), and the end plate thickness of the sealing shell 10 (that is, the rear cover plate thickness te of the rear cover 123) is different from the end plate thickness of the pressure vessel (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4). Of course, in other embodiments, the sealing shell inner diameter R2 of the sealing shell 10 may be the same as the pressure vessel inner diameter R1 of the pressure vessel T, the barrel thickness of the sealing shell 10 (that is, the sealing shell barrel wall thickness tc of the barrel 122) may be the same as the barrel thickness of the pressure vessel T (that is, the pressure vessel barrel wall thickness Tc of the pressure vessel barrel T3), and the end plate thickness of the sealing shell 10 (that is, the rear cover plate thickness te of the rear cover 123) may be the same as the end plate thickness of the pressure vessel (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4).
