The rotation of the worm 15 drives the worm gear 13 to drive the positioning frame 8 and the filter cylinder 7 connected in sequence to rotate, and the mesh gap size between the filter cylinder 7 and the coarse screen of the screen barrel 6 can be adjusted according to the actual needs of screening, so that it can be suitable for different raw material powder screening needs of attapulgite catalyst production. Compared with the prior art, there is no need to go through invalid screening steps, which reduces the time consumed for screening raw materials for attapulgite catalyst production and improves the screening efficiency of raw materials for attapulgite catalyst production;

[0022] See also Figure 1 In this embodiment, two bases 3 are fixedly connected to the bottom of the casing 1, and the two bases 3 are symmetrically arranged. The base 3 is arranged on one side of the motor 2. The contact between the two bases 3 and the ground expands the contact area between the casing 1 and the ground, and the placement stability of the casing 1 is improved; one side of the casing 1 is rotatably connected to a cover 4, one side of the cover 4 is tightly attached to the casing 1, and the other side of the cover 4 is fixedly connected to a handle 5, one side of the handle 5 is fixedly connected to a plurality of short-circuit rods, and the short-circuit rods are fixedly connected to the cover 4, and the cover 4 can be closed by rotating the cover 4 to fit the casing 1.

[0023] It should be noted that two limit rods 12 are fixedly connected to one side of the screen barrel 6, and the positioning frame 8 includes three driven rods integrally formed therewith, and the limit rods 12 are arranged on both sides of one of the driven rods. The setting of the two limit rods 12 limits the range of movement of the positioning frame 8, thereby improving the mesh gap adjustment efficiency between the screen barrel 6 and the filter cylinder 7;

[0024] See also Figure 2 In this embodiment, a collecting groove is provided at the bottom of the casing 1, a collecting box 9 is slidably connected in the collecting groove, a plurality of auxiliary pulleys 10 are rotatably connected in the collecting groove, the auxiliary pulleys 10 are slidably connected to the collecting box 9, and the collecting box 9 is arranged at the bottom of the casing 1. When the raw material powder is sieved out, it will hit the inner wall of the casing 1 and slide down along the inner wall to the inside of the collecting box 9 for collection, and the arrangement of the auxiliary pulleys 10 reduces the sliding friction between the collecting box 9 and the collecting groove, so that the movement of the collecting box 9 is smoother;

[0025] It should be noted that a knob 14 is rotatably connected to one side of the side frame 11, and the knob 14 is fixedly connected to the worm 15. The surface of the knob 14 is printed with anti-slip patterns, which increases the sliding friction on the surface of the knob 14 and makes it easier to hold the knob 14 and apply force to drive the worm 15 to rotate.

[0026] Working principle: Before use, apply force to the knob 14 to drive the worm 15 to rotate, and use the worm 15 to drive the worm wheel 13, the positioning frame 8 and the filter barrel 7 connected in sequence to rotate, while the screen barrel 6 is restricted by the driving end of the motor 2 and does not move. According to the raw material screening requirements of the attapulgite catalyst production, the mesh gap between the filter barrel 7 and the screen barrel 6 is adaptively adjusted. After the adjustment is completed, cancel the force applied to the knob 14, and use the self-locking characteristics between the worm 15 and the worm wheel 13 to fix the state between the filter barrel 7 and the screen barrel 6, then remove the feed cover 16, and put the attapulgite catalyst into the feed cover 16. The raw materials for the production of the chemical agent are poured into the screen barrel 6 from the feed port, and then the feed cover 16 is covered and the machine cover 4 is rotated to fit the casing 1 to close it, and then the motor 2 is started to drive the screen barrel 6 to rotate. The centrifugal force generated when the screen barrel 6 rotates will throw the attapulgite-type catalyst production raw materials that are smaller than the mesh gap size between the filter cylinder 7 and the screen barrel 6 onto the inner wall of the casing 1, and slide along the inner wall of the casing 1 to the collection box 9 for collection and screening. Compared with the prior art, the mesh size required for screening can be accurately adjusted, and there is no need to go through an invalid screening process, which saves the time required for screening.
