If they are not screened out, the chemical raw materials will be mixed unevenly, which will affect the production efficiency and processing time of the chemical raw materials. The chemical raw materials enter from the feed hopper 3 and are screened through the screen 5. Large particles of impurities are intercepted by the screen 5. At the same time, the drive motor 10 is started, and its output end drives the rotating shaft 11 and the cam 12 to rotate. When the cam 12 contacts the arc block 9, it squeezes the spring 8 and pushes the arc block 9 and the screen 5 to reciprocate, so that the chemical raw materials on the screen 5 are vibrated under the reaction force of the spring 8 and the cooperation of the damper, making it easier to screen through the screen 5. Large particles will be discharged through the discharge port, which is convenient for screening larger particles in the raw materials and ensuring the uniformity of mixing. At the same time, the screen 5 is vibrated to improve the screening effect.

[0023] See also Figure 1-3 As shown, a connecting shaft 13 is rotatably installed between the inner walls of the bottom end of the feed hopper 3, and a limiting plate 14 is installed on the outer wall of the connecting shaft 13. A telescopic rod 15 is installed on one side of the feed hopper 3, and a mounting seat 16 is fixed to the bottom side of one end of the limiting plate 14. The active end of the telescopic rod 15 slides through the interior of the feed hopper 3 and is mounted on the inner wall of the mounting seat 16 through a pin shaft. During operation, in the mixing process, the feeding of chemical raw materials too fast or too slow will affect the mixing of the raw materials. The telescopic rod 15 is telescoped to adjust the distance between the limiting plate 14 and the inner wall of the bottom end of the feed hopper 3, so as to control the flow rate of the raw materials, that is, when the telescopic rod 15 drives its active end to extend, the distance between the limiting plate 14 and the inner wall of the feed hopper 3 is shortened, and the flow rate of the raw materials passing through is small. When the active end of the telescopic rod 15 is shortened, the distance between the limiting plate 14 and the inner wall of the feed hopper 3 is enlarged, and the flow rate of the raw materials passing through is large, thereby avoiding excessive feeding at one time, resulting in uneven mixing of the raw materials.

[0024] See also Figure 1-2As shown, a stirring motor 17 is installed at the bottom side of the mixing barrel 2, and a stirring shaft 18 is installed at the output end of the stirring motor 17. One end of the stirring shaft 18 is arranged to penetrate the interior of the mixing barrel 2, and four groups of four stirring rods 19 are fixedly installed at equal intervals on the outer wall of the stirring shaft 18;

[0025] A conical bucket 20 is fixed at the top of the stirring shaft 18, and six baffles 21 are fixed at equal intervals on the outer wall of the conical bucket 20;

[0026] Four supporting legs 1 are fixedly installed at equal intervals on the bottom side of the mixing barrel 2, and a perspective window 22 is opened inside the outer wall of the mixing barrel 2; when working, chemical raw materials are raw materials used in chemical industry production. In the production process of chemical raw materials, several raw materials need to be poured into the reaction cylinder for mixing reaction, and then the products are produced. The screened raw materials enter the mixing barrel 2 through the bottom end of the feed hopper 3 and fall on the conical bucket 20. The stirring motor 17 drives the stirring shaft 18 to rotate, so that the conical bucket 20 drives the baffle 21 to rotate, thereby expanding the dispersion area of ​​the raw materials entering the mixing barrel 2, and the stirring shaft 18 will drive the stirring rod 19 to mix the raw materials when rotating, and the mixing situation can be observed through the perspective window 22 during the mixing process.

[0027] Working principle: chemical raw materials enter from the feed hopper 3 and are screened through the screen 5. Large particles of impurities are intercepted by the screen 5. At the same time, the drive motor 10 is started, and its output end drives the rotating shaft 11 and the cam 12 to rotate. When the cam 12 contacts the arc block 9, it will squeeze the spring 8 and push the arc block 9 and the screen 5 to reciprocate, so that the chemical raw materials on the screen 5 are vibrated under the reaction force of the spring 8 and the cooperation of the damper, and are more easily screened through the screen 5. Large particles will be discharged through the discharge port, which is convenient for screening larger particles in the raw materials to ensure the uniformity of mixing. At the same time, the screen 5 is vibrated to improve the screening effect;

[0028] The distance between the limit plate 14 and the inner wall of the bottom end of the feed hopper 3 is adjusted by the telescopic operation of the telescopic rod 15, so as to control the flow rate of the raw materials. That is, when the telescopic rod 15 drives its active end to extend, the distance between the limit plate 14 and the inner wall of the feed hopper 3 is shortened, and the flow rate of the raw materials passing through is small. When the active end of the telescopic rod 15 is shortened, the distance between the limit plate 14 and the inner wall of the feed hopper 3 is enlarged, and the flow rate of the raw materials passing through is large, thereby avoiding the phenomenon of excessive feeding at one time, which leads to uneven mixing of the raw materials.

[0029] The screened raw materials enter the mixing barrel 2 through the bottom end of the feed hopper 3 and fall onto the conical bucket 20. The stirring motor 17 drives the stirring shaft 18 to rotate, so that the conical bucket 20 drives the baffle 21 to rotate, thereby expanding the dispersion area of ​​the raw materials entering the mixing barrel 2. When rotating, the stirring shaft 18 will drive the stirring rod 19 to mix the raw materials. During the mixing process, the mixing situation can be observed through the perspective window 22.
