Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mixer mainly used for producing cement paste and the like.

[Conventional technology]

As this type of mixer, the present inventor previously proposed a mixer for paste (not disclosed in Japanese Utility Model Application No. 61-22526).

The above mixer is a cylindrical mixing drum in which powder such as cement is input together with a liquid such as water through openings at both ends of the drum, and a screw that generates thrust inward from both ends pumps the powder to the center of the mixing drum. The paste is fed into the center, and the compression and shearing effects that occur in the center are used as the primary dispersion effect.Then, along with the pressure effect, the blades generate upward thrust to force the paste into the narrow passage. After increasing the flow velocity and colliding with the colliding body with the discharge force to give a secondary dispersion effect, it is returned to the mixing drum via a pair of inclined sliders on the left and right and returns to the mixing drum in a short time. This is to obtain the degree of dispersion of particles.

[Problem that the invention attempts to solve]

The paste mixer described above is extremely suitable for kneading a paste with good fluidity.

However, the above-mentioned mixer uses a screw that generates thrust inward from both ends, and performs kneading while circulating, and cannot perform continuous kneading work, resulting in poor kneading efficiency. had become very bad.

Moreover, the structure is complicated, making manufacturing extremely troublesome.

[Means for solving problems]

The present invention attempts to solve the above-mentioned problems of the conventional products all at once. A vane plate 6 that generates thrust upward, and a partition disc 5 located in front of the vane plate 6 and provided on the screw 2.
and a colliding body 7 arranged above the wing plate 6 and having an adjustable inclination angle.

[Effect]

In the paste mixer according to the present invention, a liquid such as water and a powder such as cement are introduced from the rear end of a mixing drum 1, and the screws 2 forcefully feed the powder toward the tip. The pumped paste is passed through the partition disk 5
After being blocked by the blades 6, the blades 6 successively jump upward at high speed, collide with the collision body 7, and disperse. The paste collided with the collision body 7 is dispersed to the left and right sides of the partition disk 5, and the paste dispersed to the rear end of the partition disk 5 flows back to the rear end of the mixing drum 1, and is again pumped by the screw 2. and is thrown up by the wing plate 6. On the other hand, the partition disk 5
The paste dispersed around the tip of the screw 2
The material is then forced to be fed toward the tip of the mixing drum 1 and subjected to a kneading action.

Thereafter, by appropriately changing the inclination angle of the colliding body 7, the paste is dispersed and sieved and kneaded to disperse the paste particles, thereby continuously producing a paste having a desired degree of dispersion.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below.

FIG. 1 shows a first embodiment, in which 1
2 is a mixing drum having the same cylindrical shape, 2 is a screw disposed horizontally in the mixing drum 1 and generates a transfer thrust toward the tip, 3 is an axis of the screw 2, and the shaft 3 is arranged separately. It is connected to the output shaft of a motor 4 with a continuously variable transmission, and rotates in a clockwise direction. 5 is a partition disk fixed to the center of the shaft 3;
The outer diameter of the mixing drum 1 is slightly smaller than the inner diameter of the mixing drum 1. Reference numeral 6 denotes a vane plate attached to the shaft 3 at the rear end of the partition disc 5, and the vane plate 6 is designed to generate hydraulic force for upward movement. Reference numeral 7 denotes a plate-shaped collision body located above the vane plate 6 and disposed within the upper bulging portion 8 of the mixing drum 1 so as to be able to freely adjust the inclination angle; Formed raw material supply port, 1
0 is a paste discharge port formed on the bottom wall of the tip.

Next, the operation of the mixer according to the present invention will be explained.

From the supply port 9, powder such as cement is sequentially supplied into the mixing drum 1 along with a required amount of liquid such as water. The supplied raw material is forced in the direction of the tip by the screw 2, collides with the partition disk 5 and is blocked, and is successively bounced upward at high speed by the vane plate 6 and collides with the colliding body 7. The collided paste is dispersed to the left and right, and the paste dispersed around the rear end of the partition disk 5 flows back to the rear end of the mixing drum 1, and is again forced into the tip direction by the screw 2 together with new raw materials, and is then transferred to the blade plate. Jumped up by 6. On the other hand, the paste dispersed around the tip of the partition disk 5 is kneaded by the screw 2 while being forced toward the tip of the mixing drum 1 to form a paste. The generated paste is then sequentially discharged from the discharge port 10. Note that it is preferable to adjust the amount of paste to be dispersed and sieved by appropriately changing the inclination angle of the colliding body 7, thereby adjusting the degree of kneading or the amount of paste produced.

FIG. 3 shows a second embodiment, in which the partition disk 5
This embodiment differs from the first embodiment in that the vane plate 6 and the collision body 7 are disposed at two corresponding locations, and the other parts are the same, and the same reference numerals indicate the same parts.

FIG. 4 shows a third embodiment, in which the partition disk 5
The difference from the first embodiment is that the vane plate 6 and the colliding body 7 are arranged at three locations at predetermined intervals, and the other parts are the same, and the same reference numerals indicate the same parts. show.

FIG. 5 shows a fourth embodiment, which differs from the first embodiment in that the partition disc 5, vane plate 6, and impacting body 7 are arranged in four locations symmetrically in front and rear, corresponding to each other. Other parts are the same, and the same reference numerals indicate the same parts.

FIG. 6 shows a fifth embodiment, which is different from the first embodiment in that the partition disk 5 and the collision body 7 are respectively arranged in correspondence and arranged in four places close to each other at equal intervals. The parts are the same, and the same reference numerals indicate the same parts.

In addition, in the second to fifth embodiments, the partition disk 5, the vane plate 6, and the collision body 7 are arranged in two to four locations, respectively, but the number of locations may be increased. Of course, the arrangement interval may also be changed as appropriate.

〔effect〕

Since the present invention is constructed as described above, the raw materials are sequentially introduced into the mixing drum 1, forced through the screw 2 and collided with the partition disk 5, and then bounced up with the vane plate 6 and collided with each other. It is possible to continuously generate a paste by colliding with the body 7 and kneading while performing dispersion and sieving.
Moreover, since the inclination angle of the colliding body 7 is adjustable, the amount of paste to be dispersed and sieved can be adjusted, and the degree of kneading or the amount of paste generated and discharged can be freely adjusted. There is. Furthermore, the structure is extremely simple compared to conventional products and can be manufactured easily.
