Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulverizer technology, specifically to a pulverizer for the production of environmentally friendly flame-retardant powder coatings. Background Technology
[0002] The pulverizer for producing environmentally friendly flame-retardant powder coatings is a specialized piece of equipment used to pulverize various raw materials during the coating production process to meet the requirements of the production process. In the existing technology, the pulverizer for producing environmentally friendly flame-retardant powder coatings generally adds the coating raw materials into the pulverizer through the feed inlet, and then pulverizes the coating raw materials by the movement of the pulverizing teeth. However, dust will be generated during the pulverizing process.
[0003] For example, Chinese utility model patent CN209379085U describes a pulverizer for paint production. A sorting screen is installed at the bottom of the primary pulverizing chamber, allowing smaller particles that meet the requirements to be discharged directly from the first outlet for use in the next process. Larger particles that do not meet the requirements enter the secondary pulverizing chamber from the second outlet for further pulverization. This design ensures effective pulverization while reducing energy consumption and improving production efficiency. A vibrating motor is installed on the sorting screen for more thorough separation, ensuring that smaller particles that meet the requirements are discharged from the first outlet and preventing them from entering the secondary pulverizing chamber from the second outlet. Furthermore, the cooperation of the first and second springs provides better shock absorption. A baffle plate is hinged at the first outlet, with its other end connected to the vibrating motor, ensuring that all materials passing through the sorting screen enter the first outlet.
[0004] The aforementioned existing technology can pulverize coating raw materials through a primary pulverizing chamber and a secondary pulverizing chamber during use. However, dust gas is generated during the pulverization process. The dust gas is dispersed into the air, causing pollution to the working environment and affecting the health of workers. At the same time, it is not convenient to collect this dust, which easily leads to waste. Utility Model Content

[0052] Reference Figures 2-4 The crushing mechanism includes a support column 9, a support plate 10, a support block 11, a crushing rod 12, a first rotating mechanism, and a second rotating mechanism. The support column 9 is rotatably disposed between the inner top wall of the crushing box 2 and the support base 4. The support column 9 extends through the support base 4 and into the recycling box 1. Multiple support plates 10 are fixedly disposed on the side wall of the support column 9, and a support block 11 is fixedly disposed on one side of the support plate 10 on the side wall of the support column 9. The crushing rod 12 is fixedly disposed between the support plate 10 and the support block 11. The first rotating mechanism is disposed inside the crushing box 2 and is used to drive the support column 9 to rotate. The second rotating mechanism is disposed inside the support block 11 and is used to drive the crushing rod 12 to rotate. The first rotating mechanism includes... The device includes a first gear ring 13, a first gear 14, and a first motor 15. The first gear ring 13 is fixedly mounted on the support column 9, and the first gear 14 is rotatably mounted on the crushing box 2. The first gear 14 meshes with the first gear ring 13. The first motor 15 is fixedly mounted on the crushing box 2, and its output end is fixedly connected to the first gear 14. The operation of the first motor 15 can drive the first gear 14 to rotate. At the same time, the meshing of the first gear 14 with the first gear ring 13 drives the support column 9 to rotate.

The drive assembly includes a fourth bevel gear 19 and a positioning rod 20. The fourth bevel gear 19 is rotatably mounted on the inner top wall of the second cavity, and the positioning rod 20 is fixedly mounted between the fourth bevel gear 19 and the inner top wall of the crushing box 2. During the rotation of the support column 9, the third bevel gear 18 can be driven to rotate around the fourth bevel gear 19. At the same time, the meshing of the third bevel gear 18 and the fourth bevel gear 19 drives the third bevel gear 18 and the second bevel gear 17 to rotate. Then, the meshing of the second bevel gear 17 and the first bevel gear 16 drives the crushing rod 12 to rotate, thereby driving the crushing teeth to further crush the paint raw materials.
[0054] Reference Figure 2 The auxiliary feeding mechanism includes a third cavity 21, an air inlet pipe 22, and a fan 23. The third cavity 21 is located inside the support base 4. Multiple air inlets are provided on the inner top wall of the third cavity 21, and a filter screen is installed inside the air inlet. The air inlet pipe 22 is installed through the side wall of the crushing box 2 and is connected to the third cavity 21. The fan 23 is located on one side of the recovery box 1. The input end of the fan 23 is connected to the recovery box 1, and the output end of the fan 23 is connected to the external environment. During the crushing process, the operator controls the fan 23 to work. The operation of the fan 23 can generate negative pressure in the recovery box 1, so that the crushed paint powder and dust can be sucked into the recovery box 1 through the feeding port 6. Then, the paint powder and dust are intercepted by the filter plate 8, so that the paint powder and dust can fall into the discharge pipe 7 for collection under the action of gravity, thereby avoiding the spread of dust and pollution of the surrounding environment.
[0055] Based on the above solution, a cleaning mechanism is also included. The cleaning mechanism is installed on the support column 9 and is used to clean the paint powder adhering to the filter plate 8. The cleaning mechanism includes a cleaning plate 24 and a fixing rod. Multiple cleaning plates 24 are arranged around the support column 9. Cleaning bristles are evenly distributed on the cleaning plates 24 and contact the filter plate 8. Fixing rods are fixedly installed at both ends of the cleaning plates 24 and the side walls of the support column 9, respectively. The rotation of the support column 9 can drive the fixing rods and the cleaning plates 24 to move, thereby facilitating the cleaning bristles to clean the paint powder adhering to the filter plate 8, thereby improving the filtration effect of the filter plate 8.
[0056] In this embodiment, during use, the operator adds the paint raw material into the screen cylinder 5 through the feed hopper 3 and then closes the feed control valve. The operator then controls the first motor 15 to operate. The operation of the first motor 15 drives the first gear 14 to rotate. Simultaneously, the meshing of the first gear 14 with the first gear ring 13 drives the support column 9 to rotate. This rotation of the support column 9 causes the crushing rod 12 and crushing teeth to move around the support column 9, thus crushing the paint raw material. Simultaneously, the rotation of the support column 9 drives the third bevel gear 18 to rotate around the fourth bevel gear 19. The meshing of the third bevel gear 18 with the fourth bevel gear 19 drives the third bevel gear 18 and the second bevel gear 17 to rotate. Furthermore, the meshing of the second bevel gear 17 with the first bevel gear 16 drives the crushing rod 12 to... The rotation of the fan 23 further crushes the paint raw materials. During the crushing process, the operator can control the fan 23 to create negative pressure in the recovery box 1, which draws the crushed paint powder and dust into the recovery box 1 through the discharge port 6. The paint powder and dust are then intercepted by the filter plate 8 and fall into the discharge pipe 7 under gravity for collection, thus preventing dust from spreading and polluting the surrounding environment. At the same time, the rotation of the support column 9 can move the fixed rod and the cleaning plate 24, which facilitates the cleaning brush to clean the paint powder attached to the filter plate 8, thereby improving the filtration effect of the filter plate 8. After crushing, the paint powder can be discharged through the discharge pipe 7 by opening the discharge control valve.
[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
