At the same time, the device for crushing analytical chemical materials has no filtering function, and the crushed chemical materials are incomplete and cannot be used directly. The operator needs to manually screen them before they can be used, thereby increasing the manual labor, and after crushing, the operator needs to take them out before mixing multiple chemical materials, and it takes a long time to mix multiple chemical materials, thereby reducing the mixing efficiency.

[0031] Working principle:

[0032] When crushing and mixing materials for analytical chemicals:

[0033] Preparation process:

[0034] The operator first pulls the handle 502 to the right to drive the bent rod 503 to move to the right along the through holes processed on the two fixed blocks 504, and at the same time compresses the two springs 505, and then inserts the filter screen 8 into the box body 11 along the slide groove processed on the box body 11. During the insertion of the filter screen 8, the handle 502 is always held. When the filter screen 8 is fully inserted into the box body 11, the handle 502 is slowly released, and the elasticity of the two springs 505 is used to make the end of the bent rod 503 press against the inner wall of the groove processed on the filter screen 8, thereby completing the fixation of the filter screen 8. The crushed chemical materials can be filtered and unqualified chemical materials can be filtered out. The operator does not need to take out the crushed chemical materials for screening, and can directly mix them.

[0035] Analytical chemical material crushing process:

[0036] The operator adds analytical chemical materials into the two cylinders 6 respectively and drops them on the surface of the filter screen 8, the surface of the filter screen 8 fits with the bottom of the cylinder 6, and then the operator places the cover plate 13 just above the box 11, and makes the multiple teeth processed on the surface of the cylinder 704 mesh with the tooth grooves processed on the inner wall of the cylinder 6, and then the operator fixes the cover plate 13 and the box 11 with bolts, and then the operator starts the power supply of the second motor 702, and the output shaft of the second motor 702 rotates to drive the disc 703 to rotate, thereby driving the multiple cylinders 704 to move, and the cylinder 704 rolls along the tooth grooves processed on the inner wall of the cylinder 6 while moving, so that the cylinder 704 can rotate while making a circular axis movement, so that the analytical chemical materials can be quickly crushed, and qualified analytical chemical materials pass through the filter screen 8 and enter the bottom of the box 11. When the analytical chemical materials are crushed, the power supply of the second motor 702 is turned off.

[0037] Analytical chemical material mixing process:

[0038] The operator starts the power supply of the first motor 9, and the output shaft of the first motor 9 rotates to drive the stirring roller 10 to rotate, so that the two analytical chemical materials are tumbled in the box 11. After a period of time, after the two analytical chemical materials are stirred, the power supply of the first motor 9 is turned off, so that the crushed analytical chemical materials can be directly mixed without taking them out and stirring them in other moving stirring equipment, which saves the time of moving the analytical chemical materials, and can quickly mix the analytical chemical materials, thereby improving the mixing efficiency of the analytical chemical materials. After the analytical chemical materials are mixed, the valve of the discharge port 2 is opened to discharge the mixed analytical chemical materials;

[0039] When the mixed analytical chemical materials are completely discharged, the operator pulls the handle 502 to the right again. When the end of the bent rod 503 slides out of the groove processed on the filter screen 8, the filter screen 8 is pulled out of the box body 11, so that the unqualified chemical materials are discharged from the discharge port 2.
