Description

Technical Field

[0001] The present application relates to the technical field of filter cabinets, and specifically to a paint mist filter cabinet. Background Art

[0002] A paint mist filtration cabinet is an air purification device used in paint spray booths. Its primary function is to filter and capture paint mist particles and other impurities generated during the painting process. Using highly efficient filter materials such as dry filter bags and labyrinth paper, the paint mist filtration cabinet boasts high capture efficiency and capacity, effectively reducing paint mist concentration in the air within the paint spray booth and protecting the safety of spray painters and related equipment.

[0003] At present, the exhaust gas treatment devices in paint spray booths include water sandblasting to remove paint mist, electrostatic paint mist removal, catalytic combustion, etc. However, these devices also have obvious drawbacks. Water sandblasting to remove paint mist has good treatment efficiency but high operating costs and complex management; electrostatic paint mist removal requires low investment and is easy to maintain and manage, but requires a high-voltage power supply and a complex control system; catalytic combustion, although it has high exhaust gas treatment efficiency and occupies a small area, has a long catalyst life, high exhaust gas treatment equipment costs, and a limited scope of application. Therefore, this application proposes a low-cost and easy-to-use paint mist filter cabinet to solve the above technical problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a paint mist filtering cabinet, which has the advantages of low cost and easy use, and solves the problems of high cost and cumbersome use of existing paint mist filtering cabinets.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a paint mist filtering cabinet, comprising an installation box, a connecting plate fixedly mounted on the inner side wall of the installation box, a number of paper cartridge filters fixedly mounted on the inner side of the connecting plate, a molecular sieve fixedly mounted on the inner side wall of the paper cartridge filter, an activated carbon filter located at the bottom of the molecular sieve fixedly mounted on the inner side wall of the paper cartridge filter, a mounting plate located on top of the connecting plate fixedly mounted on the inner side wall of the installation box, a number of bag filters fixedly mounted on the inner side of the mounting plate, and an adsorbent filled on the inner side of the bag filters;

[0006] The top of the installation box is connected to an exhaust fan, the front surface of the installation box is hinged with a box door, the front surface of the box door is fixedly installed with a pull ring, the bottom of the installation box is fixedly installed with a connection box, the inner side wall of the connection box is rotatably connected to a transmission rod, and the outer side of the transmission rod is fixedly installed with two transmission bevel gears;

[0007] Two fixing plates are fixedly installed on the inner side wall of the connecting box, and a connecting rod is rotatably connected to the inner side of the fixing plate. A driven bevel gear meshing with a transmission bevel gear is fixedly installed on the top of the connecting rod, and a screw rod is fixedly installed on the bottom of the connecting rod. A moving mechanism is installed between the two screw rods. The right side of the connecting box is rotatably connected to a handwheel fixedly connected to the transmission rod. Four fixing rods are fixedly installed on the bottom of the connecting box, and a pad is fixedly installed on the bottom of the fixing rod.

[0008] By adopting the above technical solution, the air in the installation box is drawn by the exhaust fan, so that the air in the paint spraying room will enter the installation box from a position where the installation box is not blocked by the box door, and the unfiltered air will flow upward through the carton filter. At the same time, the molecular sieve and activated carbon filter in the carton filter will filter the unfiltered air, and the air that has undergone preliminary filtration will pass through the bag filter. The adsorbent in the bag filter will filter the air for the second time, and the air that has been filtered twice will be discharged from the exhaust fan, which makes it cheaper to filter the air in the paint spraying room and more convenient to use. In addition, when the paint mist filter cabinet needs to be moved, the hand wheel is turned, and the hand wheel drives the transmission bevel gear on the outside of the lifting plate to rotate, and the transmission bevel gear drives the screw at the bottom of the driven bevel gear to rotate, and the screw drives the universal wheel at the bottom of the outer lifting plate to move downward. When the universal wheel touches the ground, it will push the pad off the ground, so that the paint mist filter cabinet can be moved more conveniently by the universal wheel. Conversely, the pad can be made to touch the ground, so that the paint mist filter cabinet has better stability when filtering the air, so that the paint mist filter cabinet can filter the air in the paint spray room with low cost and more convenient use.

[0009] Furthermore, a barrier net located on top of the adsorbent is fixedly mounted on the inner side wall of the bag filter.

[0010] By adopting the above technical solution, it is possible to prevent the adsorbent in the bag filter from being sucked out when the exhaust fan extracts air.

[0011] Furthermore, a handle is fixedly mounted on the rear surface of the installation box, and a sponge cover is fixedly mounted on the outer side of the handle.

[0012] By adopting the above technical solution, it is more convenient to move the paint mist filter cabinet by the handle when the universal wheel contacts the ground.

[0013] Furthermore, the fixing plate is symmetrically fixedly mounted on the inner side wall of the connection box, a bearing is fixedly mounted on the inner side wall of the fixing plate, and the connecting rod is fixedly mounted at the axis of the bearing.

[0014] By adopting the above technical solution, when the connecting rod rotates in the fixing plate, the friction between the connecting rod and the fixing plate is smaller, thereby improving the service life of the connecting rod and the fixing plate.

[0015] Furthermore, the bottom of the screw rod is rotatably connected to the inner wall of the connection box.

[0016] By adopting the above technical solution, the screw rod has better stability when driving the lifting plate to move up and down.

[0017] Furthermore, the moving mechanism includes a lifting plate threadedly connected between the outer sides of the two screw rods, two clearance holes are opened at the bottom of the connection box, and four universal wheels are fixedly installed on the top of the lifting plate.

[0018] By adopting the above technical solution, the improved moving mechanism can make the paint mist filtering cabinet more convenient when it needs to be moved.

[0019] Furthermore, the universal wheels are arranged in groups of two and are located inside the clearance hole.

[0020] By adopting the above technical solution, the universal wheel can be moved out of the connection box more conveniently, thereby lifting the paint mist filter cabinet.

[0021] Furthermore, a molecular sieve is fixedly mounted on the inner side wall of the paper box filter, and an activated carbon filter located at the bottom of the molecular sieve is fixedly mounted on the inner side wall of the paper box filter.

[0022] By adopting the above technical solution, the air can be better filtered through the molecular sieve and the activated carbon filter.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The paint mist filtering cabinet uses an exhaust fan to draw the air in the installation box, so that the air in the paint spraying room will enter the installation box from a position where the installation box is not blocked by the box door, and the unfiltered air will flow upward through the carton filter. At the same time, the molecular sieve and activated carbon filter in the carton filter will filter the unfiltered air, and the air that has undergone preliminary filtration will pass through the bag filter. The adsorbent in the bag filter will filter the air for the second time, and the air that has been filtered twice will be discharged from the exhaust fan, which makes it cheaper to filter the air in the paint spraying room and more convenient to use. In addition, when the paint mist filter cabinet needs to be moved, the hand wheel is turned, and the hand wheel drives the transmission bevel gear on the outside of the lifting plate to rotate, and the transmission bevel gear drives the screw at the bottom of the driven bevel gear to rotate, and the screw drives the universal wheel at the bottom of the outer lifting plate to move downward. When the universal wheel touches the ground, it will push the pad off the ground, so that the paint mist filter cabinet can be moved more conveniently by the universal wheel. Conversely, the pad can be made to touch the ground, so that the paint mist filter cabinet has better stability when filtering the air, so that the paint mist filter cabinet can filter the air in the paint spray room with low cost and more convenient use.

At the same time, the molecular sieve 4 and the activated carbon filter 5 in the paper box filter 3 will filter the unfiltered air, and the air that has been preliminarily filtered will pass through the bag filter 7. The adsorbent 8 in the bag filter 7 will filter the air for the second time, and the air that has been filtered twice will be discharged from the exhaust fan 9, which makes it cheaper to filter the air in the paint spraying room and more convenient to use.

[0034] See also Figure 2-4 In this embodiment, a connection box 13 is fixedly installed at the bottom of the installation box 1, and a transmission rod 14 is rotatably connected to the inner side wall of the connection box 13. Two transmission bevel gears 15 are fixedly installed on the outer side of the transmission rod 14.

A screw rod 19 is fixedly installed on the bottom of the connecting rod 17. The bottom of the screw rod 19 is rotatably connected to the inner wall of the connecting box 13, and a moving mechanism 20 is installed between the two screw rods 19.
