Description

Technical Field

[0001] This utility model relates to the technical field of dust removal and filtration equipment, specifically to a paint mist filtration module that can be quickly replaced. Background Technology

[0002] Paint mist filtration modules are key components for purifying paint mist exhaust gases in industrial painting processes. They come in various types, including dry, wet, and electrostatic. These modules effectively remove particulate matter and volatile organic compounds from the paint mist, ensuring a safe workshop environment and compliant exhaust emissions. They also protect ventilation and other equipment from paint mist corrosion.

[0003] Dry filter modules remove paint mist through physical methods. They often use glass fiber, paper fiber, or activated carbon as filter media and are made into structures such as filter screens and honeycomb paper boxes. After the paint mist exhaust gas enters the module, the particles are intercepted by the filter screen or adsorbed by the porous media due to inertial collision, so that the purified gas meets the emission standards. The module structure has the advantages of simple structure, low cost, and convenient maintenance.

[0004] During use, dry filter modules inevitably accumulate dust and impurities over time. These impurities gradually clog the pores, leading to a decrease in the module's filtration efficiency. Therefore, the filter module needs to be disassembled and replaced regularly. Many existing filter modules use bolt fastening or snap-fit ​​connection methods, which requires operators to remove each bolt individually during disassembly and installation, greatly increasing the replacement operation time.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] See attached document Figure 1-8 A paint mist filter module that can be quickly replaced includes a housing body 1, a filter mechanism 3 is provided inside the housing body 1, the filter mechanism 3 includes a limiting frame 301, the top and bottom side walls of the limiting frame 301 are respectively connected to second pulleys 302, and the inner walls on both sides of the housing body 1 are respectively fixed with linear guide rails, and the limiting frame 301 can slide out from the housing body 1 through the second pulleys 302.

[0032] Ventilation pipes 2 are provided on both sides of the outer shell 1. The ventilation pipes 2 on both sides can respectively complete the work of air intake and air exhaust. When the gas to be filtered enters from one ventilation pipe 2, it will be discharged from the other ventilation pipe 2 after being filtered by the filtration mechanism 3. The ventilation pipes 2 extend into the outer shell 1 at one end close to each other. The side walls of the limiting frame 301 are respectively attached to the side walls of the ports of the ventilation pipes 2 on both sides, thereby ensuring that the gas does not leak during the processing.

[0033] The top and bottom of the limiting frame 301 are rotatably connected to the first pulleys 303, which are arranged sequentially along the top and bottom walls of the limiting frame 301, and a dry filter module is provided between the first pulleys 303.

[0034] The dry filtration module includes a filter screen 305, and a connecting frame 304 is fixed to the outer edge of the filter screen 305. The top and bottom walls of the connecting frame 304 are respectively rotatably connected to the first pulley 303. The connecting frame 304 is movablely connected to the limiting frame 301, so that it can be easily pulled out from the limiting frame 301 during replacement and maintenance, thereby greatly shortening the operation time during maintenance.

[0035] A pop-out limiting mechanism 7 is provided between the bottom wall of the limiting frame 301 and the side wall of the connecting frame 304, and the connecting frame 304 is movably connected to the limiting frame 301 through the pop-out limiting mechanism 7.

[0036] The pop-out limiting mechanism 7 includes a limiting hole 701 and a spring pin 702. The limiting hole 701 is formed in the bottom wall of the limiting frame 301. The spring pin 702 is fixedly connected to the side wall of the connecting frame 304. The movable end of the spring pin 702 is inserted into the limiting hole 701. A return spring 703 is fixedly installed on the side wall of the limiting frame 301. A push plate 704 is fixedly connected to the end of the return spring 703 near the connecting frame 304. The side wall of the connecting frame 304 corresponds to the push plate 704. When the connecting frame 304 is completely placed inside the limiting frame 301, the protrusion on the side wall of the connecting frame 304 will... The push plate 704 presses the return spring 703. At this time, the bottom end of the spring pin 702 is inserted into the limiting hole 701 on the bottom wall of the limiting frame 301 to achieve the limiting fixation between the connecting frame 304 and the limiting frame 301. When it is necessary to pull the connecting frame 304 out of the limiting frame 301, the spring pin 702 can be pushed upward. At this time, the limiting relationship between the connecting frame 304 and the limiting frame 301 is released. At this time, the pressed return spring 703 will push the connecting frame 304 out through the push plate 704 under the action of elastic force, so that the operator can easily take out the connecting frame 304.

[0037] The bottom of the filter mechanism 3 is provided with a displacement mechanism 5, which includes a transmission belt 502 and a pressure rod 505. A connecting block 503 is provided between the transmission belt 502 and the bottom wall of the limiting frame 301.

Transmission wheels 501 are respectively sleeved at both ends of the transmission belt 502. Support seats are provided on both sides of the transmission wheels 501. The transmission wheels 501 are rotatably connected to the support seats through a rotating shaft. The support seats are fixedly connected to the bottom wall of the outer shell 1. When the transmission wheels 501 rotate, the transmission belt 502 drives the limiting frame 301 to slide out or slide in from the outer shell 1 along the linear guide rail through the connecting block 503.

[0038] A gear 504 is fixedly connected to one side of the shaft of the transmission wheel 501. The pressure rod 505 is L-shaped. A limiting groove 506 is provided on the side of the pressure rod 505 near the gear 504. The limiting groove 506 corresponds to the gear 504. The pressure rod 505 is rotatably connected to the gear 504. The bottom end of the pressure rod 505 is slidably connected to the bottom wall of the outer shell 1. When the pressure rod 505 moves downward, it drives the gear 504 to rotate through the meshing relationship between the limiting groove 506 and the gear 504, thereby realizing the rotation of the transmission wheel 501.

The closing door 4 slides along the side wall of the outer casing 1. A limiting plate 6 is connected to the bottom of the closing door 4. A limiting groove is provided on the surface of the limiting plate 6. One end of the pressure rod 505 is inserted into the limiting groove. When the closing door 4 moves left and right, the limiting groove of the limiting plate 6 can drive the pressure rod 505 to move up and down. The up and down movement of the pressure rod 505 drives the gear 504 and the transmission wheel 501 to rotate in both directions. The rotation of the transmission wheel 501 realizes the rotation of the transmission belt 502. The rotation of the transmission belt 502 drives the limiting frame 301 to slide in or out of the outer casing 1. The opening and closing of the closing door 4 can realize the entry and exit of the limiting frame 301 from the outer casing 1, thereby shortening the time for replacing and installing the filter module.

[0040] Working principle: When the filter screen 305 inside the outer shell 1 needs to be replaced, push the closing door 4. At this time, the limiting plate 6 at the bottom of the closing door 4 starts to drive the pressure rod 505 to move downward. When the pressure rod 505 moves downward, it drives the gear 504 and the transmission wheel 501 to rotate. Through the rotation of the transmission wheel 501, the transmission belt 502 can drive the limiting frame 301 to slide out from the outer shell 1. At this time, pull the spring pin 702. Under the elastic force of the return spring 703, the push plate 704 will push out the connecting frame 304. At this time, the operator can take out the connecting frame 304. After cleaning or replacing the filter screen 305, push the connecting frame 304 back into the limiting frame 301 and pull the closing door 4 again. At this time, the limiting frame 301 retracts into the outer shell 1, and the closing door 4 is closed.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
