[0002] Powder refers to materials in a powder state. Powder processing mostly uses pulverizers. By pulverizing raw materials to a certain precision, qualified powder materials can be obtained. However, powder processing easily generates a large amount of dust. In order to reduce environmental pollution and reduce the waste of valuable powder resources, it is generally necessary to install a powder pulverizing dust removal system for powder processing equipment.

[0003] The prior art discloses a dust collector with powder recovery function, with publication number CN202221397166.8. This invention uses a grinding chamber to grind powder, and then uses a fan and filter box to extract and remove dust generated inside the grinding chamber. However, adding a separate fan increases the manufacturing cost of the dust removal mechanism. Furthermore, while using filtrate to filter the dust achieves good dust removal, it results in damp filtered powder, requiring subsequent sedimentation and drying for resource recovery. Therefore, its practicality is limited. To address these shortcomings, those skilled in the art have proposed a powder grinding and dust removal system. Utility Model Content

The dust collector has several dust removal fan blades fixedly installed on the fan shaft at the dust removal outlet duct. A mounting plate is symmetrically fixedly installed on the inner wall of the dust collector box. A dust removal filter cloth is installed inside the mounting frame. Mounting screw holes are correspondingly opened on the mounting plate and mounting frame, and mounting bolts are screwed into the mounting screw holes. A fixing frame is fixedly installed on the top surface of the crushing box and the dust collector box, and a transmission box is fixedly installed at the top of the fixing frame. A large gear is installed at one end of the crushing shaft inside the transmission box. A cleaning shaft is installed inside the transmission box, and a medium gear is fixedly installed at one end of the cleaning shaft inside the transmission box. A small gear is fixedly installed at one end of the fan shaft inside the transmission box. A suction pipe is installed connecting the inner cavities of the crushing box and the dust collector box.

[0006] Furthermore, a rotating frame is fixedly installed on the cleaning shaft within the dust collector cavity, and a dust removal brush is fixedly installed on the rotating frame. A material receiving hopper is fixedly installed on the bottom surface of the dust collector cavity, and a dust discharge pipe is connected to the bottom surface of the material receiving hopper cavity, with a dust discharge valve installed on the dust discharge pipe.

[0010] Furthermore, a control panel is fixedly installed on the outer wall of the crushing box, and the control panel is electrically connected to the crushing motor and the dust discharge valve.

[0011] Furthermore, the bottom end of the mounting frame abuts against the top surface of the receiving hopper seat, and the top end of the mounting frame abuts against the top surface of the inner cavity of the dust collector.

[0012] Compared with the prior art, the present invention provides a powder pulverizing and dust removal system, which has the following beneficial effects:

[0013] (1) This utility model is provided with a mounting bracket, a crushing box, a dust collection box and a mounting frame. The crushing box is fixedly mounted on the mounting bracket, and a crushing shaft is installed inside the crushing box. One end of the crushing shaft is connected to the output end of a crushing motor. The dust collection box is fixedly mounted on the mounting bracket, and a fan shaft is installed inside the dust collection box. An air outlet is opened on the bottom surface of the inner cavity of the dust collection box, and one end of the air outlet is connected to a dust collection air outlet pipe. Several dust collection fan blades are fixedly mounted on the part of the fan shaft located in the dust collection air outlet pipe. The inner wall of the dust collection box is symmetrical. A mounting plate is fixedly installed, and a dust collector filter cloth is installed within the mounting frame. The mounting plate and frame have corresponding mounting screw holes, into which mounting bolts are screwed. A mounting bracket is fixedly installed on the top surface of the crushing box and dust collector box, and a transmission box is fixedly installed at the top of the mounting bracket. A large gear is installed at one end of the crushing shaft within the transmission box cavity, and a cleaning shaft is installed within the transmission box cavity, with a medium gear fixedly installed at one end of the cleaning shaft within the transmission box cavity. The large gear and the medium gear mesh with each other, and the medium gear and the small gear mesh with each other. Therefore, during use, workers can feed the raw materials to be crushed into the crushing chamber through the feed hopper. The crushing motor drives the crushing shaft and the corresponding crushing mechanism to crush the raw materials. The resulting powder is then discharged through the discharge port. When the crushing shaft rotates, it drives the large gear to rotate, which in turn drives the medium and small gears to rotate. The small gear then drives the fan shaft and dust collector blades to rotate. At this time, the speed of the fan shaft is greater than that of the crushing shaft. By rotating the dust collector blades, air can be extracted from the dust collector chamber, thereby generating negative pressure inside the dust collector chamber. The system is designed with a suction pipe connecting the inner cavity of the crushing chamber and the inner cavity of the dust collector. The suction pipe can be used to draw the powder and dust generated in the crushing chamber into the dust collector. When the air containing powder and dust passes through the dust collector filter cloth, the dust and dust can be intercepted and filtered by the dust collector filter cloth. This allows the powder crushing and dust removal system to use the crushing motor to drive the dust removal mechanism, which helps to reduce the manufacturing cost of the dust removal mechanism. Furthermore, the use of the dust collector filter cloth for dry dust removal facilitates the subsequent recycling and reuse of powder and dust, making it more practical.

[0014] (2) This utility model is provided with an installation frame, a dust removal filter cloth and a cleaning shaft. As mentioned above, the dust removal filter cloth is installed in the installation frame. The frame supports the dust removal filter cloth in a semi-circular shape. The cleaning shaft is fixedly installed in the inner cavity of the dust removal box with a rotating frame and a cleaning brush. When the gear rotates, it can drive the cleaning shaft to rotate. The cleaning shaft drives the cleaning brush to automatically clean the dust material attached to and blocked on the dust removal filter plate, so as to ensure the dust removal efficiency of the dust removal filter cloth. The bottom surface of the inner cavity of the dust removal box is fixedly installed with a receiving hopper. The powder material cleaned by the cleaning brush can fall into the receiving hopper for collection. The bottom surface of the inner cavity of the receiving hopper is connected to a dust discharge pipe. When the worker needs to collect and recycle the collected powder material, the dust discharge valve can be opened to allow the powder material in the receiving hopper to be discharged through the dust discharge pipe, thus bringing convenience to the efficient recycling of valuable powder material collected by the dust removal, making it more convenient to use and more practical.

[0032] In one embodiment, the bottom end of the mounting frame 24 abuts against the top surface of the receiving hopper seat 15, and the top end of the mounting frame 24 abuts against the top surface of the inner cavity of the dust collector 10.

[0033] Working Principle: This utility model includes a mounting bracket 1, a crushing box 5, a dust collection box 10, and a mounting frame 24. The crushing box 5 is fixedly mounted on the mounting bracket 1, and a crushing shaft 9 is installed inside the crushing box 5. One end of the crushing shaft 9 is connected to the output end of a crushing motor 2. The dust collection box 10 is fixedly mounted on the mounting bracket 1, and a fan shaft 11 is installed inside the dust collection box 10. An air outlet 14 is opened on the bottom surface of the inner cavity of the dust collection box 10, and one end of the air outlet 14 is connected to a dust collection air outlet pipe 3. Several dust collection fan blades 13 are fixedly mounted on the fan shaft 11 at the dust collection air outlet pipe 3. Mounting plates 25 are symmetrically fixedly mounted on the inner wall of the dust collection box 10. A dust collection filter cloth 12 is installed inside the mounting frame 24. Mounting screw holes 28 are correspondingly provided on the mounting plate 25 and mounting frame 24, and mounting bolts 17 are screwed into the mounting screw holes 28. A fixing frame 6 is fixedly installed on the top surface of the crushing box 5 and the dust collection box 10, and a transmission box 8 is fixedly installed on the top of the fixing frame 6. A large gear 19 is installed at one end of the inner cavity of the transmission box 8, and a cleaning shaft 16 is installed in the inner cavity of the transmission box 8. A medium gear 20 is fixedly installed at one end of the cleaning shaft 16 in the inner cavity of the transmission box 8. The large gear 19 and the medium gear 20 mesh with each other, and the medium gear 20 meshes with the small gear 21. Therefore, in use, the worker can introduce the powder raw material to be crushed into the inner cavity of the crushing box 5 through the feed hopper 7, and use the crushing motor 2 to drive the crushing shaft 9 and the corresponding crushing mechanism. The raw materials are crushed and processed, and the resulting powder is discharged through the discharge port 4. When the crushing shaft 9 rotates, it drives the large gear 19 to rotate, which in turn drives the medium gear 20 and the small gear 21 to rotate. The small gear 21 then drives the fan shaft 11 and the dust collector blades 13 to rotate. At this time, the speed of the fan shaft 11 is greater than that of the crushing shaft 9. By rotating the dust collector blades 13, air can be extracted from the inner cavity of the dust collector 10, thereby creating a negative pressure in the inner cavity of the dust collector 10.

The dust is intercepted and filtered, allowing the dust removal system to be driven by the pulverizing motor 2, thus reducing the manufacturing cost of the dust removal mechanism. Furthermore, the use of the dust filter cloth 12 for dry dust removal facilitates subsequent recycling and reuse of the powder dust, enhancing its practicality. This invention includes an installation frame 24, a dust filter cloth 12, and a cleaning shaft 16. As described above, the dust filter cloth 12 is mounted on the installation frame 24, which supports it in a semi-circular shape. The cleaning shaft 16 is located within the dust collection chamber 10 and is fixedly mounted with a rotating frame 26. A cleaning brush 27 is fixedly mounted on the rotating frame 26. When the gear 20 rotates, it drives the cleaning shaft 16 to rotate.The cleaning shaft 16 drives the cleaning brush 27 to automatically clean the dust adhering to and clogging the dust collector filter plate, ensuring the dust removal efficiency of the dust collector filter cloth 12. A collection hopper 15 is fixedly installed on the bottom surface of the inner cavity of the dust collector box 10. The powder cleaned by the cleaning brush 27 falls into the collection hopper 15 for collection. A dust discharge pipe 22 is connected to the bottom surface of the inner cavity of the collection hopper 15. When workers need to collect and recycle the collected powder, they can open the dust discharge valve 23 to allow the powder in the collection hopper 15 to be discharged through the dust discharge pipe 22. This facilitates the efficient recycling of valuable powder collected by the dust collector, making it more convenient and practical.
