Technical Field

[0001] The embodiments disclosed herein relate to the field of powder coating filtration technology, and more specifically, to a powder coating fine multi-stage filtration device. Background Technology

[0002] Powder coating is a new type of solvent-free solid powder coating. Compared with liquid coating, it has fewer raw material components and no solvent evaporation, which makes it solvent-free, pollution-free and with high mechanical strength of the coating film. It is widely used in various industries such as home appliances.

[0003] In the powder coating production process, the ground materials need to undergo further fine screening to obtain products that meet the requirements. When using existing fine multi-stage filtration devices for powder coating, some material particles that are similar in size to the filter holes on the filter screen are easily stuck in the filter holes. After long-term use, the filter holes on the filter screen are prone to large-area blockage, which can easily affect the filtration of powder coating. Utility Model Content

[0043] like Figures 1-4As shown, at least one embodiment of this disclosure provides a multi-stage filtration device for refining powder coatings, including a filter box 1. The top of the filter box 1 is inclined, and a feed inlet is provided on one side of the filter box 1. A feed box 17 is fixedly connected to the feed inlet to gather and transport the material into the filter box 1. Multiple discharge outlets are provided at the bottom of the filter box 1, and a guide box 18 is fixedly connected to each of the multiple discharge outlets to output the filtered material out of the filter box 1. The device also includes a base frame 2, multi-stage filter plates 3, and a diverter frame 5. The multi-stage filter plates 3 are fixedly connected to the bottom of multiple slide rods 11 in an inclined state. Two diverter frames 5 are provided, and both diverter frames 5 are fixedly connected to the inner wall of the filter box 1. The diversion frame 5 divides the interior of the filter box 1 into multiple flow guiding spaces 6. Through the cooperation between the base frame 2, multi-stage filter plates 3, rotating mechanism, support mechanism and diversion frame 5, the material is filtered in multiple stages through the filter holes of different sizes opened on the multi-stage filter plates 3. When the multi-stage filter plates 3 become clogged, the setting of the rotating mechanism and support mechanism makes it easy to flip the filter box 1 and knock the multi-stage filter plates 3, thereby shaking out the material blocked in the filter holes. The material slides out of the feed port through the inclined surface of the filter box 1 and is discharged outside the filter box 1, which facilitates the quick cleaning of the multi-stage filter plates 3, reduces the clogging of the multi-stage filter plates 3 and reduces the impact on the filtration of coating powder.

[0044] The filter box 1 is mounted inside the base frame 2 via a rotating mechanism for driving the filter box 1 to rotate within the base frame 2. The rotating mechanism includes a rotating shaft 7, a rotating gear 8, a drive gear 9, and a first motor 10. There are two rotating shafts 7, both of which are rotatably connected inside the base frame 2. The filter box 1 is fixedly connected to one end of the two rotating shafts 7 to support the rotation of the filter box 1. The rotating gear 8 is fixedly connected to the rotating shaft 7, and the drive gear 9 is rotatably connected inside the base frame 2. The drive gear 9 meshes with the rotating gear 8. The first motor 10 is mounted on one side of the base frame 2, and the output end of the first motor 10 passes through the base frame 2 and is fixedly connected to the drive gear 9.

[0045] The first motor 10 drives the drive gear 9 to rotate, and the drive gear 9 rotates, which in turn drives the rotating gear 8 to rotate, thereby causing the rotating shaft 7 and the filter box 1 to rotate 180 degrees.

[0046] The multi-stage filter plate 3 is installed inside the filter box 1 by a support mechanism. Two baffles 4 are fixedly connected to the top of the multi-stage filter plate 3. Several filter holes of different sizes are opened on both the multi-stage filter plate 3 and the two baffles 4, arranged in sections on the multi-stage filter plate 3. The support mechanism includes: slide rods 11, a top frame 12, support springs 13, and a vibration assembly. Multiple slide rods 11 are provided, and each slide rod 11 is fixedly connected to the top of the multi-stage filter plate 3. Multiple sliding holes corresponding to the slide rods 11 are opened at the top of the filter box 1, and a slide rod 11 is slidably connected to each sliding hole. The top frame 12 is fixedly connected to the top of the multiple slide rods 11. Multiple support springs 13 are provided, and a support spring is fitted onto each slide rod 11. Spring 13, multiple support springs 13 are fixedly connected at both ends to the top frame 12 and the filter box 1 respectively. The vibration assembly is set at the top of the filter box 1 and is used to drive the slide rod 11 to make the multi-stage filter plate 3 vibrate. The vibration assembly includes: fixed plate 14, eccentric wheel 15 and second motor 16. The circumferential surface of the eccentric wheel 15 contacts the top frame 12. There are two fixed plates 14. Both fixed plates 14 are fixedly connected to the top of the multi-stage filter plate 3. The eccentric wheel 15 is rotatably connected between the two fixed plates 14 through the rotating rod 19 to support the eccentric wheel 15 to strike the top frame 12. The second motor 16 is installed on one of the fixed plates 14. The output end of the second motor 16 passes through the fixed plate 14 and is fixedly connected to one end of the rotating rod 19.

[0047] The second motor 16 drives the rotating rod 19 and the eccentric wheel 15 to rotate. When the eccentric wheel 15 rotates, it strikes the top frame 12. The vibration generated by the top frame 12 being struck is transmitted to the multi-stage filter plate 3 through the slide rod 11. The support spring 13 rebounds the top frame 12, causing the multi-stage filter plate 3 to vibrate continuously. This allows the material to be filtered in multiple stages through filter holes of different specifications.

[0048] Working principle: When multi-stage filtration of materials is required, the material is poured into the filter box 1 through the feed box 17. The second motor 16 drives the rotating rod 19 and the eccentric wheel 15 to rotate. When the eccentric wheel 15 rotates, it strikes the top frame 12. The vibration generated by the strike on the top frame 12 is transmitted to the multi-stage filter plate 3 through the sliding rod 11. The support spring 13 rebounds the top frame 12, causing the multi-stage filter plate 3 to vibrate continuously. This allows the material to be filtered through filter holes of different sizes. The filtered material... The material is discharged from the filter box 1 through multiple guide spaces 6 and guide boxes 18. When the multi-stage filter plate 3 becomes clogged, the first motor 10 drives the drive gear 9 to rotate. When the drive gear 9 rotates, it drives the rotating gear 8 to rotate, thereby causing the rotating shaft 7 and the filter box 1 to rotate 180 degrees. Then, the multi-stage filter plate 3 continues to vibrate, shaking out the material stuck in the filter holes. The material falls onto the inner wall of the filter box 1 through the inclined surface set at the top of the filter box 1 and rolls out of the feed port, thereby cleaning the multi-stage filter plate 3.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
