Description

Technical Field

[0001] The utility model relates to the technical field of powder coating processing, in particular to an indoor dust-proof device for powder coating. Background Art

[0002] In the process of producing powder coatings, the powder coatings are poured into the mixer from the feed port for stirring, which will raise a large amount of dust, causing great damage to the workshop environment, causing pollution to the workshop and the surrounding environment, and causing harm to the health of operators. In order to reduce the dispersion of dust, a dust prevention device will be installed at the feed port of the mixer.

[0003] However, the dust suction head on the existing powder coating indoor dust prevention device has a small dust suction area, which will cause serious dust scattering at the feed inlet of the mixer, resulting in poor dust prevention effect, and the filter cartridge used to filter dust needs to be disassembled and cleaned from the inside of the filter box, which makes the operation more troublesome. In view of the above problems, it is urgent to make an innovative design based on the original powder coating indoor dust prevention device. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides a technical solution: a dust prevention device for a powder coating indoor includes a mixer 1, a feed port 2 is arranged on one side of the top of the mixer 1, a dust suction head 3 is fixed on the top of the mixer 1 outside the feed port 2, an inner cavity 4 is provided inside the dust suction head 3, and a dust suction port 5 is provided inside the inner cavity 4;

[0024] A filter box 7 is fixed to the other side of the top of the mixer 1 through a support rod 6. The filter box 7 and the dust collector head 3 are fixedly connected through a connecting pipe 8. An air pump 9 is installed on the top of the filter box 7. The air inlet end of the air pump 9 is located inside the filter box 7, and the air outlet end of the air pump 9 is located outside the filter box 7. A filter cartridge 10 is fixed to the top of the filter box 7, and a bottom plate 11 is fixed to the bottom of the filter cartridge 10.

[0025] A cleaning mechanism is provided on the outside of the filter cartridge 10 .

[0026] The cleaning mechanism includes a support plate 12. The inner wall of the filter box 7 is located below the bottom plate 11 and is fixed with the support plate 12. The top of the support plate 12 is rotatably mounted with a rotating shaft 13 through a bearing. The top of the rotating shaft 13 passes through the top of the filter box 7 and is fixed with a solid gear 16. The outer wall of the rotating shaft 13 is rotatably connected to the inner side of the top of the filter box 7 through a bearing. A hollow gear 17 is meshed with one side of the solid gear 16. The outer wall of the hollow gear 17 is rotatably connected to the inner side of the top of the filter box 7 through a bearing. The outer side of the rotating shaft 13 is located inside the filter box 7 and is provided with a movable ring 14. A brush 15 is fixed to the inner wall of the movable ring 14. The end of the brush 15 is in contact with the outer wall of the filter cartridge 10. The top of the solid gear 16 is fixedly connected to the output end of the bottom of the servo motor 18. The outer wall of the servo motor 18 is fixed to the top of the filter box 7 through a frame.

[0027] A discharge port 19 is provided at the bottom of the filter box 7, and a sealing cover 20 is threadedly installed at the bottom of the discharge port 19. The dust collected inside the filter box 7 can be discharged through the discharge port 19, so that the dust can be recycled.

[0028] The dust collector head 3 and the inner cavity 4 are both designed as a "U"-shaped structure, and the dust suction ports 5 are evenly distributed on the inner side of the dust collector head 3, which increases the dust suction area at the feed port 2, effectively preventing the dust at the feed port 2 from scattering into the room, and protecting the indoor workers.

[0029] There are four rotating shafts 13 and solid gears 16 distributed at equal angles about the central axis of the hollow gear 17. The four rotating shafts 13 are threadedly connected to the movable ring 14, ensuring that when the hollow gear 17 rotates, the four solid gears 16 and the four rotating shafts 13 can rotate synchronously, allowing the movable ring 14 to move upward or downward.

[0030] The brushes 15 are distributed at equal angles with respect to the central axis of the movable ring 14 , ensuring that the dust adsorbed on the outside of the filter cartridge 10 can be cleaned when the brushes 15 move up and down.

[0031] Working principle: When using the indoor dust prevention device for powder coating, first start the vacuum pump 9, then the vacuum pump 9 generates suction force at the dust suction port 5 through the filter box 7, the connecting pipe 8 and the inner cavity 4. When the raw materials for preparing powder coating are put into the mixer 1 through the feed port 2, dust will be generated at the feed port 2. At this time, suction force is generated at the dust suction port 5, and the dust enters the filter box 7 through the inner cavity 4 and the connecting pipe 8. Finally, the dust is adsorbed to the outside of the filter cartridge 10.

[0032] When too much dust is adsorbed on the outside of the filter cartridge 10, affecting dust filtration, the servo motor 18 is started at this time, and then the servo motor 18 drives the solid gear 16 to rotate, and then the solid gear 16 drives the hollow gear 17 to rotate, and then the hollow gear 17 drives the other three solid gears 16 to rotate, so that the four solid gears 16 rotate at the same time, and then the four solid gears 16 drive the four rotating shafts 13 to rotate. Since the rotating shaft 13 and the movable ring 14 are threadedly connected, the movable ring 14 and the brush 15 move downward to clean up the dust adsorbed on the outside of the filter cartridge 10 and drop it to the bottom of the filter box 7, and the sealing cover 20 is rotated to discharge the collected dust through the discharge port 19.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
