[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example, by Figure 1-3 The utility model discloses a waste silver catalyst recovery device, comprising a reactor 1, a grinding box 2 and a servo motor 3. The grinding box 2 is provided on the top of the reactor 1. The output end of the crushing roller in the grinding box 2 is fixedly connected to the servo motor 3 for driving the rotation of the main crushing roller. A collection box 4 is sleeved on the top of the reactor 1 and located below the grinding box 2. The collection box 4 is fixedly connected to the grinding box 2. A chute 6 is provided on the inner wall of the collection box 4. A cleaning component is provided on the inner side of the collection box 4.

[0022] The cleaning assembly includes a connecting rod 7 and a brush 8. The end of the slider 54 is fixedly connected to the connecting rod 7 in the collection box 4. The top of the connecting rod 7 is fixedly connected to the brush 8 by screws. The movement of the slider 54 drives the connecting rod 7 to move accordingly.

[0023] Specifically, the top of the brush 8 contacts the grinding roller in the grinding box 2 and is used to clean the waste silver catalyst powder on the grinding roller;

[0024] Specifically, a collecting partition 9 is fixedly connected to the inner side of the collecting box 4 and below the connecting rod 7 to collect the fallen waste silver catalyst powder;

[0025] A sliding drive assembly 5 is provided on the outside of the collection box 4 for driving the movement of the cleaning assembly. The drive assembly 5 includes a connecting block 51, a bidirectional threaded rod 52, a turning handle 53 and a slider 54. The connecting block 51 is fixedly connected to the outside of the collection box 4. The bidirectional threaded rod 52 is rotatably connected to the inside of the connecting block 51. The outer side of the bidirectional threaded rod 52 is threadedly connected to the slider 54. The end of the bidirectional threaded rod 52 is fixedly connected to the turning handle 53.

[0026] Specifically, the slider 54 is located on the inner side of the slide groove 6 , and the rotation of the bidirectional threaded rod 52 can drive the slider 54 to slide along the inner side of the slide groove 6 .

[0027] Working principle: When in use, the servo motor 3 drives the crushing roller in the grinding box 2 to rotate, and the waste silver catalyst is ground. Then, under the action of the collecting partition 9 in the collecting box 4, the ground waste silver catalyst is guided to the inner side of the reactor 1. After grinding, there will be waste silver catalyst residue on the crushing roller in the grinding box 2. Then, the staff can turn the handle 53 to drive the bidirectional threaded rod 52 to rotate, so that the slider 54 moves along the inner side of the slide 6, and then the connecting rods 7 in the collecting box 4 can be brought closer to each other, and the horizontal position of the connecting rod 7 in the collecting box 4 can be adjusted so that the top of the brush 8 contacts the crushing roller. At this time, with the rotation of the crushing roller, the brush 8 will form a cleaning effect on the crushing roller, and then clean the waste silver catalyst remaining on the crushing roller to prevent the residual waste silver catalyst powder from adhering to the surface of the crushing roller, which is convenient for operation and ensures the measurement of the waste silver catalyst powder dropped into the reactor 1, which will not affect the recovery of the waste silver catalyst.

[0028] Similarly, turning the handle 53 can restore the slider 54 to its initial position, making it convenient and quick to grind the waste silver catalyst next time.

[0029] At the same time, the connecting rod 7 and the brush 8 are fixedly connected by screws, which can realize the installation and disassembly of the connecting rod 7 and the brush 8, making it easy to clean or replace the brush 8.
