Description

Technical Field

[0001] This utility model relates to the field of dust removal devices, and in particular to a dust removal device for coating production. Background Technology

[0002] In the paint production process, traditional dust removal technology often uses water bath filtration combined with filter cartridges to purify the factory air. However, in traditional technology, the filter cartridge is first installed in the housing through a fixed structure, and then the top cover is fixed with screws. This arrangement makes filter cartridge replacement cumbersome, requiring multiple disassembly and assembly steps to complete, which seriously affects maintenance efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a dust removal device for paint production, which solves the problem of cumbersome filter replacement steps in traditional paint factory dust removal and filtration devices.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A dust removal device for paint production includes a water bath, with an air inlet pipe connected to the lower front end of the water bath and an air outlet pipe connected to the upper rear end of the water bath. A partition is fixed to the upper end of the inner wall of the water bath, which divides the inner cavity of the water bath into an upper and lower filter chamber and a water bath chamber. The water bath chamber and the filter chamber are connected through a round hole in the middle of the partition.

[0006] A filter element is inserted into the top of the partition, covering a round hole. The filter element is pressed against the top of the partition by a cover plate inserted into the top of the water bath, and the cover plate is fixed to the top of the water bath by bolts.

[0007] Optionally, a ring is fixed on the top surface of the partition, the axis of the ring coincides with the axis of the circular hole, and the inner diameter of the ring is larger than the inner diameter of the circular hole. The filter element is cylindrical, and the lower end of the filter element is inserted into the ring.

[0008] Optionally, the inner wall of the cover plate is fixed with multiple elastic abutments. While the cover plate is fixed to the top of the water bath, the elastic abutments all abut against the top of the filter element, applying a vertically downward elastic force to the filter element, so that the filter element is pressed against the partition plate.

[0009] Optionally, the elastic abutment includes a sleeve fixed to the inner wall of the cover plate, a slide rod slidably inserted into the inner wall of the sleeve, a spring inserted into the upper end of the inner wall of the sleeve, one end of the spring connected to the slide rod and the other end connected to the inner wall of the cover plate, and an abutment plate fixed to the bottom of the slide rod, the diameter of the abutment plate being larger than the diameter of the slide rod.

[0010] Optionally, two limiting grooves are symmetrically formed on the side wall of the sleeve, and a limiting strip is fixed to the top surface of the slide rod. The two ends of the limiting strip are respectively inserted into the two limiting grooves, and the lower end of the spring abuts against the top surface of the limiting strip.

[0011] Optionally, an outer ring is fixed to the outer side of the upper end of the water bath tank, and a cover plate is fitted on the outer side of the outer ring. The lower end of the outer wall of the outer ring forms an inclined surface extending towards the center of the outer ring. Bolts are threadedly connected to the middle of the four sides of the cover plate through threaded holes, and the ends of the bolts abut against the inclined surface.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] When the cover plate of this utility model is fixed by bolts, the elastic clamping structure on its inner wall simultaneously applies downward pressure to the filter element, so that the filter element is firmly pressed against the partition plate. No additional fixing steps are required, and the cover plate installation and filter element positioning can be completed in one operation, which greatly simplifies the filter element replacement process.

[0014] This invention uses the bolt end to abut against the inclined surface of the outer ring. When fixed, the cover plate is pulled downward, which causes the cover plate to fit tightly against the sealing gasket on the top surface of the outer ring. The inclined surface guides and increases the clamping force, effectively preventing the leakage of unfiltered gas and improving the sealing performance of the dust removal device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 7 This embodiment provides a dust removal device for paint production, including a water bath 1. The lower front end of the water bath 1 is connected to an air inlet pipe 2, and the upper rear end is connected to an air outlet pipe 3. A partition 4 is fixed to the upper end of the inner wall of the water bath 1. The height of the partition 4 is lower than the height of the air outlet pipe 3. It divides the inner cavity of the water bath 1 into two parts, namely a filter chamber 5 and a water bath chamber 6. The height of the air inlet end of the air inlet pipe 2 is higher than the height of the partition 4, thus ensuring that the liquid in the water bath chamber 6 will not overflow from the upper end of the air inlet pipe 2.

[0025] The filter chamber 5 and the water bath chamber 6 are connected by a round hole 7 in the middle of the partition 4. The dust-laden gas generated during production enters the water bath chamber 6 through the air inlet pipe 2. After preliminary treatment in the water bath, it enters the filter chamber 5 through the round hole 7. As for the power of gas pumping, the gas is drawn by connecting a power unit such as an air pump to the air outlet pipe 3. The air inlet pipe 2 is connected to the factory building through a pipeline to achieve the effect of drawing air from the factory building.

[0026] Furthermore, a water pipe is installed at the lower end of the water bath 1 on the side opposite to the air inlet pipe 2. A valve is fixed on the water pipe. By opening the valve, water for the water bath can be added to the water bath 1 or water can be drained.

[0027] A circular ring 8 is fixed on the top surface of the partition 4. The axis of the circular ring 8 coincides with the axis of the circular hole 7, and the inner diameter of the circular ring 8 is larger than the inner diameter of the circular hole 7. A cylindrical filter element 9 is provided on the top of the partition 4. The filter element 9 can cover the circular hole 7, and its lower end is inserted into the circular ring 8. The circular ring 8 plays a preliminary positioning role for the filter element 9, preventing the filter element 9 from shifting significantly before installation.

[0028] An outer ring 10 is fixed to the outer side of the upper end of the water bath tank 1. The lower end of the outer wall of the outer ring 10 forms an inclined surface 1001 extending towards the center of the outer ring 10. A cover plate 11 is fitted onto the outer side of the outer ring 10. Bolts 12 are threadedly connected to the middle of the four sides of the cover plate 11 through threaded holes. The ends of the bolts 12 abut against the inclined surface 1001. When the bolts 12 are tightened, the ends of the bolts 12 will apply downward force along the inclined surface 1001, thereby pulling the cover plate 11 downward. A sealing gasket 13 is fixed to the inner wall of the cover plate 11 at the position opposite to the outer ring 10. Tightening the cover plate 11 at the same time compresses the sealing gasket 13, ensuring the sealing of the filter chamber 5 and preventing external gas from entering the filter chamber 5 from the cover plate 11 during suction.

[0029] Multiple elastic abutments are fixed to the inner wall of the cover plate 11. Each elastic abutment includes a sleeve 14 fixed to the inner wall of the cover plate 11. A slide rod 15 is slidably inserted into the inner wall of the sleeve 14. Two limiting grooves 16 are symmetrically opened on the side wall of the sleeve 14. A limiting strip 17 is fixed to the top surface of the slide rod 15. The two ends of the limiting strip 17 are respectively inserted into the two limiting grooves 16, which can prevent the slide rod 15 from rotating or falling out inside the sleeve 14. A spring 18 is inserted into the upper end of the inner wall of the sleeve 14. The lower end of the spring 18 abuts against the top surface of the limiting strip 17, and the upper end is connected to the inner wall of the cover plate 11. A pressing plate 19 is fixed to the bottom of the slide rod 15. The diameter of the pressing plate 19 is larger than the diameter of the slide rod 15, which can increase the contact area with the filter element 9.

[0030] When installing filter element 9, first insert the lower end of filter element 9 into ring 8, then put cover plate 11 on outer ring 10 and tighten bolt 12. Cover plate 11 is pulled downward, at which point the clamping plate 19 at the bottom of slide rod 15 will first contact the top of filter element 9. As bolt 12 continues to tighten, slide rod 15 slides upward, limiting strip 17 moves upward in limiting groove 16, spring 18 is compressed, and spring 18 will apply a downward elastic force to slide rod 15, which is transmitted to filter element 9 through clamping plate 19, making filter element 9 firmly pressed against partition 4. In this process, no additional fixing steps are required. The clamping and fixing of filter element 9 is completed at the same time as fixing cover plate 11, which greatly facilitates the replacement of filter element 9.

[0031] At the same time, the downward movement of the cover plate 11 will cause the sealing gasket 13 between the cover plate 11 and the top surface of the outer ring 10 to fit tightly. The guiding effect of the inclined surface 1001 allows the force of the bolt 12 to be more effectively converted into the clamping force on the sealing gasket 13, which effectively prevents unfiltered gas from leaking from the gaps and improves the sealing performance of the entire device. The clean gas filtered by the filter element 9 can then be discharged from the outlet pipe 3.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
