[0021] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0022] As Figure 1-6 shown, the utility model provides a technical solution: a multi-stage raw material screening device for allopurinol production, including a main body 1. A discharge port 18 is opened on one side of the main body 1. Three baffles 19 are arranged on the side of the main body 1 close to the first pulley 4. By arranging the baffles 19, the baffles 19 can block the raw materials in the main body 1 during the screening operation of the device, so that the raw materials will not fall into the material taking cabinet 21 in advance;

[0023] A collection box 20 is fixedly connected to the side of the main body 1 close to the discharge port 18. A sliding groove 22 is opened on one side of the collection box 20. A material taking cabinet 21 is arranged in the sliding groove 22. A handle 23 is arranged on one side of the material taking cabinet 21. By arranging the collection box 20, after the device finishes screening the raw materials, the raw materials can fall into the collection box 20 through the discharge port 18, so that the screened raw materials can be collected more conveniently;

[0024] Three linking columns 8 are arranged on the inner side wall of the main body 1. A mounting plate 9 is installed at one end of the linking column 8 far away from the main body 1. A return spring 10 is movably connected under the mounting plate 9. A limit post 11 is arranged under the return spring 10. An assembly groove 12 is opened on one side of the limit post 11. A screening plate 13 is arranged on the inner side wall of the assembly groove 12. An assembly plate 14 is installed at one end of the screening plate 13. By arranging the return spring 10, the return spring 10 can continuously drive the screening plate 13 to vibrate through the elastic force, so that the screening plate 13 can screen the raw materials on the surface of the screening plate 13 to the lower screening plate 13;

[0025] One side of the assembly plate 14 close to the screening plate 13 is fixedly connected with a snap block 15. A feed inlet 2 is arranged on the main body 1. A motor 3 is fixedly connected to the main body 1. There are four first belt pulleys 4 on one side of the motor 3. One of the first belt pulleys 4 is fixed to the output shaft of the motor 3. A second belt pulley 6 is arranged on one side of the main body 1. The same drive belt 5 is sleeved outside two opposite first belt pulleys 4. The second belt pulley 6 is fixed to the two first belt pulleys 4 in the middle. Above the mounting plate 9, there are diamond-shaped blocks 7. The three diamond-shaped blocks 7 are respectively installed at the ends of the three first belt pulleys 4. A screening cavity 16 is formed inside the main body 1. A screening box 17 is arranged at the bottom inside the main body 1. By arranging the first belt pulley 4, the first belt pulley 4 can drive the second belt pulley 6 to rotate together, so that the diamond-shaped blocks 7 on the first belt pulley 4 rotate and strike the mounting plate 9, and can drive a plurality of screening plates 13 to screen the raw materials at the same time.

[0026] The working principle of the present utility model is as follows:

[0027] The staff first pour the raw materials into the main body 1 through the feed inlet 2, and then start the motor 3, so that the motor 3 drives the second belt pulley 6 to rotate through the first belt pulley 4 and the drive belt 5 on its outer arc surface, so that a plurality of diamond-shaped blocks 7 strike the mounting plate 9, and then continuously collide and extrude the screening plate 13. As the screening plate 13 is extruded downward, the return spring 10 is also extruded. The screening plate 13 is driven to vibrate by the extrusion of the diamond-shaped block 7 and the rebound of the return spring 10 to screen the raw materials on the screening plate 13;

[0028] After the screening plate 13 finishes screening the raw materials, pull open the baffle 19 so that the screening plate 13 can vibrate to shake the raw materials on the surface into the material taking cabinet 21. Subsequently, if it is necessary to clean or replace the screening plate 13, the snap block 15 in the assembly groove 12 can be squeezed, so that the snap block 15 pops out of the assembly groove 12, so that the assembly plate 14 drives the screening plate 13 to pop out of the mounting plate 9, enabling the staff to replace or clean the screening plate 13. Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
