[0024] In this embodiment, please refer to Figure 4 The mounting part 5 includes a displacement plate 51, which is movably connected to the inner cavity of the mounting groove 13, a rubber column 52 is fixedly connected to one side of the displacement plate 51, a spring 53 is fixedly connected to the outer edge of the rubber column 52 on one side of the displacement plate 51, a linkage plate 54 is fixedly connected to one end of the rubber column 52, a movable shaft 55 is fixedly connected to one side of the linkage plate 54, and a positioning block 56 is fixedly connected to the outer side of the movable shaft 55.

[0025] In this embodiment, please refer to Figure 2-3The output end of the second motor 7 is fixedly connected to a driving shaft 47, and one end of the driving shaft 47 is fixedly connected to a second bevel gear 48. The outer edge of the second bevel gear 48 is meshed with the outer edge of the first bevel gear 44, which is conducive to the second motor 7 to provide power to control the driving shaft 47 to drive the second bevel gear 48 to rotate. Since the second bevel gear 48 is meshed with the outer edge of the first bevel gear 44, the first bevel gear 44 can be driven to rotate in the opposite direction, so that the second stirring paddle 46 and the first stirring paddle 42 rotate in opposite directions, so that the raw materials in the inner cavity of the reaction tank 1 are stirred more evenly.

[0026] In this embodiment, please refer to Figure 2 The front side of the reaction tank 1 is provided with an installation opening on one side of the filter plate 3, and a sealing plug 12 is installed on the inner wall of the installation opening. One side of the sealing plug 12 is transitionally matched with the inner cavity of the installation opening, which is beneficial to prevent the raw materials in the inner cavity of the reaction tank 1 from leaking through the installation opening.

[0027] In this embodiment, please refer to Figure 2 , Figure 4 A fixing plate 57 is fixedly connected to one end of the inner wall of the mounting groove 13, and a limiting groove 58 is provided on one side of the fixing plate 57, and the inner wall of the limiting groove 58 is adapted to the outer side of the positioning block 56, which is conducive to the positioning block 56 passing through the limiting groove 58 after a slight rotation, and the positioning block 56 cannot pass through the limiting groove 58 after a slight rotation again.

The number of the first displacement blocks 511 and the first displacement blocks 511 are the same and are staggered with each other, which is beneficial for the displacement plate 51 to rotate slightly when the linkage plate 54 moves backward and the second displacement blocks 541 and the first displacement blocks 511 are squeezed.

[0029] Working principle of this utility model:

[0030] Step 1, in the utility model, a first motor 6 is provided, and power is given by the first motor 6 to control the rotation of the power rod 41, and the rotation of the power rod 41 drives the three first stirring paddles 42 to rotate, so as to stir the raw materials in the inner cavity of the reaction tank 1, and at the same time, a second motor 7 is provided, and power is given by the second motor 7 to control the rotation of the driving shaft 47, and the rotation of the driving shaft 47 drives the second bevel gear 48 to rotate. Since the outer edge of the second bevel gear 48 is meshed with the outer edge of the first bevel gear 44, the rotation of the second bevel gear 48 drives the first bevel gear 44 to rotate, and the rotation of the first bevel gear 44 drives the linkage frame 45 to rotate, and the rotation of the linkage frame 45 drives the three second stirring paddles 46 to rotate in the inner cavity of the reaction tank 1, so as to stir the raw materials in the inner cavity of the reaction tank 1, and the first stirring paddle 42 and the second stirring paddle 46 are controlled to rotate in different directions respectively, so as to fully stir the raw materials in the inner cavity of the reaction tank 1, thereby improving the stirring effect of the raw materials;

[0031] Step 2, in the utility model, after the sealing plug 12 is removed, the filter plate 3 is pressed by external force, so that the movable shaft 55 is moved backward under pressure, and the movable shaft 55 moves backward to push the linkage plate 54 to move backward, and the linkage plate 54 moves backward to squeeze the rubber column 52 and the spring 53 to deform them, and when the linkage plate 54 moves backward, the second displacement block 541 is squeezed with the first displacement block 511, and the displacement plate 51 is slightly rotated under pressure, and the displacement plate 51 rotates to drive the rubber column 52 to rotate, thereby driving the linkage plate 54 and the movable shaft 55 to rotate, and the movable shaft 55 rotates to cause the blocking block 56 to rotate slightly, and when the blocking block 56 rotates slightly, it can pass through the limiting groove 58. When the filter plate 3 is pressed, the spring 53 loses its pressure and returns to its original state, and the linkage plate 54 is lifted up to move it forward. The movable shaft 55 is moved forward by the linkage plate 54 moving forward. At this time, the blocking block 56 can pass through the limiting groove 58, so that the travel distance of the movable shaft 55 becomes longer, so that the movable shaft 55 continues to move forward, and the filter plate 3 is lifted up so that one side of it is separated from the inner cavity of the reaction tank 1 from the installation and removal port, so that the filter plate 3 can be taken out of the inner cavity of the reaction tank 1. When installing, the filter plate 3 is pressed again to move the movable shaft 55 and the blocking block 56 backward, and rotate slightly again, so that the blocking block 56 cannot pass through the limiting groove 58, so that the position of the movable shaft 55 is fixed, and the filter plate 3 is reinstalled into the inner cavity of the reaction tank 1.
