By adopting the design of the sub-control valve 120, when the content of the particles in the separated edible oil exceeds the standard, the oil can be directly returned, and the edible oil is injected into the oil inlet device 4 for direct secondary separation.
Referring to fig. 10 and 11, a bristle holder 14 is fixedly installed at the outer wall of the movable tube 127, bristles 144 are annularly distributed at the outer end surface of the bristle holder 14, the spherical end of the movable tube 127 is positioned at the center of a plurality of bundles of bristles 144, and after the movable tube 127 is extended, the bristles 144 act on the inner wall of the annular recess 661.
In the above technical solution, the movable tube 127 is continuously ejected by the continued outward movement of the pushing block 133, so that the bristles 144 are kept in contact with the inner wall of the annular recess 661, and the apparatus enters the cleaning mode.
In the cleaning mode, high-temperature water is injected into the oil inlet device 4, pumped into the extrusion assembly 7 through the oil pump, and flows out into the centrifugal barrel 61 from the extrusion assembly 7, and under the flushing of the high-temperature water, the centrifugal barrel 61 rotates at a speed of 500 revolutions per minute, and the attached fine solid particles are cleaned by the contact of the bristles 144 and the annular concave part 661, and the cleaned sewage is pumped out through the first oil pump 116 until the water flowing out from the first oil outlet pipe 118 is cleaned.
After cleaning is complete, the push block 133 is retracted, causing the spring to rebound, retracting the movable tube 127 into place.
The brush hair is thick brush hair with the wire diameter larger than 0.8mm, even if the brush hair falls off, the falling brush hair can be easily separated by adding a filter screen at the position of oil outlet.
Referring to fig. 2 and 12, the extrusion assembly 7 includes an extrusion roller 71, one end of the extrusion roller 71 passes through the slag box 62 and then extends into the centrifugal barrel 61, the end is closed, a first hollow shaft 72 is fixed at the other end of the extrusion roller 71, the second driving device 10 is connected and drives the first hollow shaft 72, the second driving device 10 is a driving motor, the second driving device 10 and the first hollow shaft 72 are also driven by a synchronous toothed belt, the hollow shaft 72 is in running fit with the machine body structure 1, the running fit is supported by a bearing, the extrusion roller 71 is also in running fit with the slag box 62, the running fit is completed by the bearing and a shaft seal, the shaft seal is sealed at the inner side of the bearing, the extrusion roller 71 is enabled to rotate more stably by the support of a double bearing, a first bracket body 74 is inserted in the first hollow shaft 72, the first bracket body 73 is fixed between the first hollow shaft 72 and the machine body joint 1, the straight pipe 73 is in running fit with the outer wall of the machine body 71, the spiral roll 71 is distributed at the other end of the straight pipe 73, the spiral roll 71 is abutted against the outer wall 75 of the centrifugal barrel 71, and the spiral roll 71 is abutted against the outer wall 75 of the spiral roll, and the spiral roll is abutted against the outer wall 71.
In the above technical solution, the rotation of the extrusion roller 71 drives the spiral sheet 75 to operate at a lower rotation speed than the centrifugal barrel 61, under the high-speed rotation of the centrifugal barrel 61, the solid particles adhere to the inner walls of the centrifugal barrel and the conical barrel, the residue is pushed out by the rotation of the spiral sheet 75, and the liquid edible oil is collected at the left end of the centrifugal barrel 61 along the spiral channel of the spiral sheet 75.
The rotation speed of the spiral sheet 75 is set according to the fluidity of the edible oil, and in the equipment debugging stage, the high-speed rotation of the centrifugal barrel 61 is maintained, the rotation speed of the spiral sheet 75 is independently regulated, and when the rotation of the spiral sheet 75 pushes the edible oil out of the slag box 62, the rotation speed of the spiral sheet 75 is excessively high, and the rotation speed needs to be reduced.
Referring to fig. 2, a plurality of dispersing tablets 771 are annularly provided at positions of the extrusion roller 71 corresponding to the tapping box 62.
The dispersion piece 771 is provided to disperse the residue when the residue is pushed out by the lump so that the residue leaks out from the tapping box 62.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
