[0002] In the production mixing process of resin abrasive tools, the static electricity accumulation between resin powder and other raw material particles such as abrasives and fillers can cause particles to attract and adhere to each other, resulting in clumping. The presence of clumps not only affects the uniformity of mixing, but also can produce defects such as air holes and cracks during the molding process, reducing the mechanical properties and service life of the product, and directly affecting the quality of the final product. Dust pollution generated during the mixing process has a profound impact on production and factory management. Dust not only pollutes the production environment, causing equipment wear and increased cleaning difficulty, but also poses a threat to workers' health. Long-term exposure to high concentrations of dust can lead to respiratory diseases. In addition, dust accumulation in the air also poses an explosion risk, especially with the use of flammable materials and powders in the production process of resin abrasive tools. Therefore, effective management of dust is crucial to ensure production safety and employee health, and is also related to the company's compliance operations and social responsibility. SUMMARY

[0013] As Figure 1 , Figure 2 and Figure 3As shown, the utility model of practical new type includes support 1, fixedly arranged mixing assembly 2 and smoke exhaust component 3 on support 1, mixing assembly 2 includes vertically placed mixing bucket 20, is provided with two spiral stirring rods 21 in mixing bucket 20 inside, two spiral stirring rods 21 are driven connection through transmission belt 22 and drive motor 23, the thread rotation direction of two spiral stirring rods 21 is opposite, still be provided with several crushing teeth 24 on the outer periphery of the thread section of spiral stirring rod 21, the exhaust port 25 is seted up on the lateral wall of mixing bucket 20, smoke exhaust component 3 is connected with mixing bucket 20 through exhaust port 25, smoke exhaust component 3 includes air inlet pipe 30, filter cartridge dust collector and air outlet pipe 31 that are sequentially connected, air inlet pipe 30 is connected with exhaust port 25, filter cartridge dust collector is vertically placed, air outlet pipe 31 is connected with filter cartridge dust collector through lift valve, ash bucket 32 is also seted up in filter cartridge dust collector bottom. The bottom of mixing bucket 20 adopts funnel type design, the discharge port 27 is located funnel bottom and is connected with external receiving box 29. In the utility model, the mixing bucket 20 is a vertically placed cylindrical container, usually made of stainless steel or carbon steel to adapt to the corrosion resistance and sanitary requirements of different materials, the inner wall of the cylinder is smooth to reduce material adhesion and ensure mixing effect; the two spiral stirring rods 21 play different roles in the mixing process, one pushes the material from the lower part of the cylinder to the upper part, and the other pushes the material from the upper part to the lower part, forming a circulating flow of the material. The spiral stirring rod 21 is usually made of stainless steel, and the width and spacing of the thread section are designed according to specific mixing requirements. The material between the two screw stirring rods 21 with different rotation directions is subjected to shear force, which makes the particles in the material constantly dispersed and mixed with each other. In addition, due to the design of the spiral belt, the material also produces a certain diffusion effect during the mixing process, which further enhances the uniform mixing effect of the material. The material convectively mixes along the inner wall of the cylinder and the spiral belt, which allows the material to be fully mixed in a short time, especially suitable for processing powders with poor flowability or materials prone to clumping.
[0014] In this embodiment, stirring assembly 28 is provided at the feed inlet 26 and discharge outlet 27 of the mixing bucket 20. The stirring assembly 28 includes two horizontally arranged stirring rods 280, each provided with a plurality of crushing teeth 24. The two stirring rods 280 are driven connected with a stirring motor 282 through a second transmission belt 281. The discharge outlet 27 can adjust the speed and quantity of discharge through a control valve. During the stirring and mixing process, the crushing teeth 24 are mainly used to prevent and solve the clumping phenomenon that may occur during mixing, ensuring uniform mixing. The crushing teeth can effectively break and disperse clumped materials through their unique structural design and working principle, optimizing the mixing effect.
[0015] Before the material enters the mixing barrel 20, it first passes through the stirring assembly 28 arranged at the feeding port 26, and the large pieces of material or the formed lumps first contact the crushing teeth 24, the crushing teeth 24 apply shearing and crushing action to the material through the sharp tooth tips or blade edges, and the material is crushed into smaller particles in the process, preventing the formation of larger lumps in the subsequent mixing process; during the mixing process, the crushing teeth 24 rotate with the spiral stirring rods 21, and the material continuously flows up and down under the pushing of the two spiral stirring rods 21 and contacts the crushing teeth 24, and the crushing teeth 24 apply continuous shearing force and impact force to the material, which not only effectively crushes new lumps, but also disperses the lumpy material into finer particles, ensuring uniformity of mixing; finally, the material again passes through the stirring assembly 28 arranged at the discharging port 27, and the mixing is stirred and crushed again, ensuring the full flow and uniform distribution of the material, avoiding the problem of secondary lumping caused by factors such as static electricity and humidity.
[0016] The filter cartridge dust collector comprises a filter cartridge 33, a centrifugal fan 34 coaxially arranged in the filter cartridge 33, and a filter screen 35 arranged between the centrifugal fan 34 and the air inlet pipe 30, and an electromagnetic pulse valve 36 is further arranged in the filter cartridge 33. After the dust-containing gas enters the filter cartridge dust collector, due to the sudden expansion of the airflow cross section and the action of the airflow distribution plate, some coarse particles in the airflow are deposited in the ash bucket 32 under the action of power and inertial force. After the fine and low-density dust particles enter the filter cartridge 33, under the action of the centrifugal fan 34, through the combined action of Brownian diffusion and screening, the dust is deposited on the filter material surface, and the purified gas is discharged from the exhaust pipe 30. The resistance of the filter cartridge dust collector increases with the increase of the thickness of the dust layer on the filter material surface, and when the resistance reaches a specified value, the ash should be cleaned. At this time, the lifting valve is closed, the filtered gas flow is cut off, and then the electromagnetic pulse valve 36 is opened, and the compressed air rapidly expands in the upper box in a short time, flows into the filter cartridge 33, and causes the filter cartridge 33 to expand and deform to vibrate. Under the action of the reverse airflow washing, the dust attached to the outer surface of the filter bag is stripped and falls into the ash bucket 32.
[0017] Finally, it should be emphasized that the above description is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
