Technical Field

[0001] This utility model belongs to the field of spray booth filtration technology, and in particular relates to a filtration device for spray booths. Background Technology

[0002] A spray booth is a closed or semi-closed space specifically designed for spray painting operations. Through scientific airflow design and filtration system, it effectively controls the diffusion of paint mist, particulate matter and volatile organic compounds (VOCs), ensuring a safe working environment and reducing environmental pollution. Spray booths are usually equipped with filtration devices to filter paint mist and particulate matter.

[0003] Traditional spray booth filtration equipment typically uses filter plates to filter paint mist and particulate matter, with the filter plates filled with fiberglass wool. However, this filtration structure usually only has one layer of filtration, resulting in insufficient filtration of paint mist and particulate matter. Furthermore, the filter plates are usually fixed inside the filter box, making them difficult to replace and prone to clogging over time, thus affecting the filtration effect. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-5 As shown, this utility model is a filtration device for a paint booth, including a filter box 1, a plurality of fans 11 mounted on the front of the filter box 1, a plurality of cover plates 12 provided on the top of the filter box 1, and further including: Spraying mechanism 2 is installed on the left and right sides of filter box 1. Spraying mechanism 2 dissolves paint mist by spraying. The filter box 1 has several openings on its top and an exhaust vent 13 on its back, with multiple blades installed inside the exhaust vent 13.

[0020] The filter box 1 is equipped with several glass fiber cotton filter plates 14. The glass fiber cotton filter plates 14 are inserted into the filter box 1 through the opening at the top of the filter box 1. The glass fiber cotton filter plates 14 are filled with glass fiber cotton. The bottom of the cover plate 12 is inserted into the opening at the top of the filter box 1. Since the filter box 1 is equipped with multiple layers of glass fiber cotton filter plates 14, the paint mist will be filtered through the multiple layers of glass fiber cotton filter plates 14. The filtered air is discharged from the exhaust port 13. This method can improve the filtration effect of paint mist and make the paint mist filtration more thorough. By removing the pressure plate 3 and pulling the cover plate 12, the glass fiber cotton filter plates 14 can be pulled out and replaced. The operation is simple and convenient and the replacement efficiency is higher. The bottom of the cover plate 12 is provided with a rubber pad, and the top of the glass fiber cotton filter plate 14 is in contact with the rubber pad at the bottom of the cover plate 12.

[0021] The cover plate 12 has two square grooves 121 inside. The top of the glass fiber cotton filter plate 14 has two square blocks 142 fixedly connected, and the top of the square blocks 142 has a threaded shaft 143 fixedly connected. The square insert 142 is adapted to the shape of the square groove 121, and the cover plate 12 is inserted into the square insert 142 through the square groove 121. The square shape of the square insert 142 is used to position the cover plate 12.

[0022] A nut is threaded onto the threaded shaft 143. After the cover plate 12 is inserted into the square insert 142, the nut is used to lock and fix the cover plate 12 and the glass fiber cotton filter plate 14. Positioning seats 141 are inserted into the left and right sides of the glass fiber cotton filter plate 14. The side of the positioning seat 141 away from the glass fiber cotton filter plate 14 is fixedly connected to the inner wall of the filter box 1. The positioning seat 141 is U-shaped and is used to position the glass fiber cotton filter plate 14.

[0023] The spraying mechanism 2 includes an outer shell 21 fixedly connected to the outside of the filter box 1. A liquid storage tank 22 is fixedly connected to the bottom of the outer shell 21. A water pump 23 is fixedly connected to the outside of the outer shell 21. A delivery pipe 24 is fixedly connected to the top outlet of the water pump 23. A drain pipe 25 is fixedly connected to the top of the inner side of the outer shell 21. A strip-shaped outlet 26 is opened at the bottom of the drain pipe 25. When the water pump 23 is started, the water in the liquid storage tank 22 is drawn into the delivery pipe 24 and delivered to the drain pipe 25. Then it is discharged from the strip-shaped outlet 26. The strip-shaped outlet 26 can increase the spraying area of ​​the water flow and mix with the paint mist over a larger area. Thus, during the painting process, the flowing water will absorb and dissolve a large amount of paint mist, thereby maintaining the air quality in the paint booth. The top of the conveying pipe 24 passes through the outer shell 21 and extends to the drain pipe 25 for fixed connection, and the conveying pipe 24 and the drain pipe 25 are interconnected.

[0024] The water inlet at the bottom of the water pump 23 is connected to the liquid storage tank 22 through a pipe, and the drain pipe 25 is set above the liquid storage tank 22. The water sprayed from the strip outlet 26 flows back into the liquid storage tank 22.

[0025] A pressure plate 3 is positioned on the top of the cover plate 12. Several threaded shafts 31 are inserted inside the pressure plate 3. The bottom of the threaded shafts 31 is fixedly connected to the top of the filter box 1. Nuts are threaded onto the threaded shafts 31. The pressure plate 3 is used to press and fix the cover plate 12.

[0026] One specific application of this embodiment is: The cover plate 12 is inserted into the square insert 142 on the glass fiber cotton filter plate 14 through the square groove 121, thus connecting the cover plate 12 and the glass fiber cotton filter plate 14. Then, a nut is installed on the threaded shaft 143 to lock and fix the cover plate 12. Multiple cover plates 12 and glass fiber cotton filter plates 14 are connected in sequence. After installation, the glass fiber cotton filter plate 14 is inserted into the filter box 1 from the top, and the glass fiber cotton filter plate 14 will be inserted into the two positioning seats 141, thereby positioning and installing the glass fiber cotton filter plate 14. When the bottom of the cover plate 12 contacts the top of the filter box 1, the installation of the glass fiber cotton filter plate 14 is completed. Then, the pressure plate 3 is placed on the cover plate 12 and inserted into the threaded shaft 31. Then, a nut is installed on the threaded shaft 31 to press and fix the pressure plate 3. At this time, the cover plate 12 is compressed, improving the fixing effect. Water is then added to the storage tank 22, and the water pump 23 is started to draw the water from the storage tank 22 into the delivery pipe 24 and then to the drain pipe 25. The water is then discharged from the strip outlet 26 and flows back into the storage tank 22. During the painting process, the flowing water will absorb and dissolve a large amount of paint mist, thereby maintaining the air quality in the paint booth. The fan 11 is started to draw the paint mist and particulate matter into the filter box 1, where the paint mist is filtered through the multi-layer glass fiber cotton filter plate 14. The filtered air is then discharged from the exhaust port 13. This method can improve the filtration effect of the paint mist and make the filtration more thorough. When it is necessary to replace the glass fiber cotton filter plate 14, the nut on the threaded shaft 31 is removed to take out the pressure plate 3, and then the cover plate 12 is pulled to pull out the glass fiber cotton filter plate 14 for replacement. The operation is simple and convenient, and the replacement efficiency is higher.
