Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of dust treatment technology, and more specifically, to an ultrafine pulverizer for powder coatings. Background Technology

[0002] In the powder coating production process, ultrafine pulverizers play a crucial role, pulverizing raw materials to a particle size that meets specific requirements, thus satisfying the high standards of powder coating performance and application. As market demands for powder coating quality continue to rise, even more stringent challenges are being placed on the pulverizing precision of pulverizers.

[0003] However, existing ultrafine pulverizers have a significant problem during operation: they generate a large amount of dust. This dust not only severely pollutes the production workshop environment and affects the health of operators, but also poses a significant safety hazard when it permeates the workshop. When the dust reaches a certain concentration in the air, it can easily explode upon contact with a source of ignition, seriously threatening the safety of production equipment and personnel.

[0036] 4. In this disclosure, by setting up the cleaning plate and cleaning bristles, the rotation of the support tube can drive the cleaning plate and cleaning bristles to move around the support tube, thereby facilitating the cleaning of dust adhering to the inner wall of the filter cartridge by the cleaning bristles, thus ensuring the filtration effect of the filter cartridge.

[0037] 5.

A fine screen is provided at the input end of the fan 13. Specifically, the operation of the fan 13 can generate negative pressure in the processing box 7, so that dust can be passed into the water tank 8 through the air inlet pipe 12 and the air inlet housing 11. The dust can be adsorbed by the water in the water tank 8, thus avoiding dust pollution to the workshop environment.

[0052] Reference Figures 2-4 The filtration mechanism includes an installation groove and a filter cylinder 10. Installation grooves are provided on both the fixing ring 9 and the inner top wall of the treatment box 7. The filter cylinder 10 is positioned between the fixing ring 9 and the inner top wall of the treatment box 7, with both ends of the filter cylinder 10 extending into the installation groove. Sealing rings are fixedly installed at both ends of the filter cylinder 10, and the sealing rings contact the bottom of the installation groove. The treatment box 7 includes a box body and a box cover. The box cover is fixed to the box body with bolts. Specifically, during the operation of the fan 13, the gas adsorbed by the water can pass through the filter cylinder 10 to filter the remaining dust in the gas, thereby further improving the dust removal effect.

[0053] Reference Figures 2-4 It also includes an adsorption mechanism, which is installed on the box cover and used to adsorb dust. The adsorption mechanism includes a first cavity, an adsorption tube 15, a water pump 16, and a rotating mechanism. The first cavity is opened inside the box cover. A support tube 14 is rotatably installed on the inner top wall of the first cavity. The bottom end of the support tube 14 is sealed and extends into the water tank 8. Multiple adsorption tubes 15 are connected to the side wall of the support tube 14. The end of the adsorption tube 15 away from the support tube 14 is sealed. Multiple nozzles are connected to the adsorption tube 15. The water pump 16 is installed on the box cover. The input end of the water pump 16 is connected to the water tank 8. The output end of the water pump 16 extends through the inner top wall of the first cavity and into the support tube 14. The rotating mechanism is set in the first cavity and is used to drive the support tube 14 to rotate. The rotating mechanism includes a first gear ring 17, a first gear 18, and a second motor 19. The first gear ring 17 The first gear 18 is fixedly mounted on the support tube 14 and rotates within the first cavity. The first gear 18 meshes with the first gear ring 17. The second motor 19 is mounted on the cover and its output end is fixedly connected to the first gear 18. Multiple stirring rods 20 are fixedly mounted on the side wall of the support tube 14 and are located within the water tank 8. A filter screen is installed at the input end of the water pump 16. Specifically, the water in the water tank 8 is filtered through the filter screen and then passed into the support tube 14 by the operation of the water pump 16. The water can then be sprayed out through the nozzle on the adsorption tube 15. At the same time, the operation of the second motor 19 drives the first gear 18 to rotate, and the meshing of the first gear 18 with the first gear ring 17 drives the nozzle to move around the support tube 14, thereby allowing the water mist sprayed from the nozzle to further clean the dust.

[0054] Reference Figure 3 and Figure 4Multiple cleaning plates 21 are arranged around the support tube 14. Cleaning bristles are evenly distributed on the cleaning plates 21 and contact the filter cartridge 10. Multiple fixing rods 22 are fixedly arranged between the cleaning plates 21 and the support tube 14. Specifically, the rotation of the support tube 14 can drive the cleaning plates 21 and the cleaning bristles to move around the support tube 14, so as to facilitate the cleaning of dust adhering to the inner wall of the filter cartridge 10 by the cleaning bristles, thereby ensuring the filtration effect of the filter cartridge 10.

[0055] In this embodiment, during use, the operator can drive the crushing column 3 to rotate via the first motor 6, thereby crushing the coating inside the crusher body 1 through the crushing teeth 5. During the crushing process, the operator controls the fan 13 to operate, which generates negative pressure in the processing box 7. This allows dust to be introduced into the water tank 8 through the air inlet pipe 12 and the air inlet housing 11, where the water in the water tank 8 can adsorb the dust, thus preventing dust from polluting the workshop environment. During the adsorption process, the operator controls the water pump 16 to operate, which filters the water in the water tank 8 through the filter screen and then introduces it into the support pipe 14. Afterward, the water can be introduced through the adsorption pipe 1. The nozzle on the 5 sprays water, and the operation of the second motor 19 drives the first gear 18 to rotate. The meshing of the first gear 18 with the first gear ring 17 drives the nozzle to move around the support tube 14, so that the water mist sprayed by the nozzle can further adsorb the dust. Then, during the operation of the fan 13, the gas adsorbed by the water can pass through the filter cartridge 10 to filter the remaining dust in the gas, thereby further improving the dust cleaning effect. At the same time, the rotation of the support tube 14 can drive the cleaning plate 21 and the cleaning bristles to move around the support tube 14, so that the cleaning bristles can clean the dust attached to the inner wall of the filter cartridge 10, thereby ensuring the filtration effect of the filter cartridge 10.
