Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a gas filtration system for a spraying line in the production of speed reducers. Background Technique

[0002] Gas filtration systems are widely used in industrial fields such as spraying lines in the production of speed reducers, and are of great significance for improving product quality, protecting the production environment, and reducing operating costs. During spraying operations, a large amount of fine paint particles will be generated. These fine paint particles will float in the air, causing relatively great harm to the human body and serious environmental pollution. The main function of the air filtration system of the spraying line is to filter these waste gases through a series of filter meshes and filtering media to achieve the purpose of purifying the air.

[0003] When the existing gas filtration device filters waste gas, the waste gas treatment effect is poor, and the waste gas cannot be effectively filtered;

[0004] The existing patent (publication number: CN216604468U) discloses an exhaust gas treatment device for spraying, which includes a frame. The frame includes a framework and a housing fixedly connected to the framework; a spraying plate connected to the middle of the framework. The spraying plate is provided with a circulation hole for gas to flow through; a first filtering component and a second filtering component. The first filtering component is located above the spraying plate, and the second filtering component is located below the spraying plate; an exhaust mechanism for discharging the gas flowing through the first filtering component and the second filtering component from the housing. It is extracted by the exhaust mechanism, and the second filtering component extracts the waste gas from above the spraying plate by using the exhaust mechanism, and collects the waste gas generated during spraying from two directions for filtration treatment. The waste gas treatment effect is good, protecting the physical health of the operators.

[0005] In view of the above problems, although the solution given by the existing patent collects the waste gas generated during spraying from two directions for filtration treatment, and the waste gas treatment effect is good, it cannot clean the impurities blocked on the surface of the filter mesh, and subsequent manual cleaning is required, resulting in too low impurities affecting the filtration effect. Summary of the Invention

[0006] The purpose of the utility model is to provide a gas filtration system for a spraying line in the production of speed reducers, which can drive the wind wheel to rotate, so that the rotation of the wind wheel drives the transmission rod to rotate synchronously, and then drives the cleaning brush to move on the outer surface of the coarse filter cylinder, and can self-clean the larger impurities blocked on the outer surface of the coarse filter cylinder, thereby reducing the influence of these larger impurities on the filtration effect and improving the practicability of the filtration system, so as to solve the problems put forward in the above background technique.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4, A gas filtration system for a reducer production spraying line, including a device housing 1. An intake pipe 2 is connected to the outer surface of the device housing 1. A filtration mechanism for filtering gas is arranged inside the device housing 1. The filtration mechanism includes a coarse filtration cylinder 3, which is placed inside the device housing 1. A first fine filtration cylinder 31 is fixed to the inner wall of the coarse filtration cylinder 3. A second fine filtration cylinder 32 is fixed to the inner wall of the first fine filtration cylinder 31. A wind wheel 33 is installed inside the second fine filtration cylinder 32. One end of the wind wheel 33 is fixed with a transmission rod 34 that penetrates the outer wall of the coarse filtration cylinder 3. One end of the transmission rod 34 is fixed with two cleaning brushes 35 that are closely attached to the outer surface of the coarse filtration cylinder 3. A fixed bearing 36 fixed to the second fine filtration cylinder 32 is sleeved on the outer surface of the transmission rod 34. A flow guide member 4 is fixed to the lower end inside the device housing 1. A connecting pipe 5 is provided at the lower end of the device housing 1 and is in communication with the flow guide member 4. The lower end of the connecting pipe 5 is threadedly connected with a collecting member 6. A sealing gasket 7 is installed on the upper surface of the device housing 1. An exhaust mechanism for exhausting gas from the device is installed above the sealing gasket 7.

[0028] By adopting the above technical solution, before using the gas filtration system of the reducer production spraying line, first install the device housing 1 in a suitable position, connect the intake pipe 2 to an external waste gas conveying device, then connect the exhaust pipe 84 on the mounting member 82 to an external exhaust device, and connect the mounting pipe 83 to an external compressed device air pipe. The external waste gas is sent by the conveying device into the device housing 1. The coarse filtration cylinder 3 can filter larger impurities in the waste gas, and the first fine filtration cylinder 31 and the second fine filtration cylinder 32 can filter smaller impurities in the waste gas. Then it enters the second fine filtration cylinder 32 and flows towards the mounting member 82. When the air flows, it can drive the wind wheel 33 to rotate, so that the rotation of the wind wheel 33 drives the transmission rod 34 to rotate synchronously, and then drives the cleaning brush 35 to move on the outer surface of the coarse filtration cylinder 3, and can self-clean the larger impurities blocked on the outer surface of the coarse filtration cylinder 3, thereby reducing the influence of these larger impurities on the filtration effect and improving the practicability of the filtration system. And through the fixed bearing 36 provided, the stability of the transmission rod 34 during rotation can be ensured. The cleaned impurities fall into the flow guide member 4 and then fall into the collecting member 6 through the connecting pipe 5 for collection.

[0029] Specifically, as Figure 1 and Figure 2 shown, the exhaust mechanism includes a fixed cover 8, which is placed on the upper surface of the device housing 1. A fixing bolt 81 threadedly connected to the device housing 1 is installed on the upper surface of the fixed cover 8. A mounting member 82 in communication with the device housing 1 is provided at the upper end of the fixed cover 8. One end of the mounting member 82 is in communication with a mounting pipe 83, and the other end of the mounting member 82 is in communication with an exhaust pipe 84.

[0030] By adopting the above technical solution, through the sealing gasket 7 between the fixed cover 8 and the device housing 1, the sealing effect can be achieved. And by unscrewing the fixing bolt 81, the fixed cover 8 can be disassembled, which is convenient for maintaining the internal parts. Through the installation pipe 83, an external air compression device can convey compressed air into the device housing 1 and blow it out from the inside to the outside of the second fine filter cartridge 32, so as to blow out the impurities blocked on the first fine filter cartridge 31, the second fine filter cartridge 32 and the upper baffle of the coarse filter cartridge 3, making the impurities fall into the collection member 6 for collection, further improving the self-cleaning effect.

[0031] Working principle: The external waste gas is sent to the inside of the device housing 1 by a conveying device. The coarse filter cartridge 3 can filter out larger impurities in the waste gas, and the first fine filter cartridge 31 and the second fine filter cartridge 32 can filter out smaller impurities in the waste gas. Then it enters the inside of the second fine filter cartridge 32 and flows towards the mounting member 82. And when the air flows, it can drive the wind wheel 33 to rotate, so that the rotation of the wind wheel 33 drives the transmission rod 34 to rotate synchronously, and then drives the cleaning brush 35 to move on the outer surface of the coarse filter cartridge 3, which can self-clean the larger impurities blocked on the outer surface of the coarse filter cartridge 3, thereby reducing the influence of these larger impurities on the filtering effect. The cleaned impurities fall into the guiding member 4 and then fall into the collection member 6 through the connecting pipe 5 for collection. By the sealing gasket 7 between the fixed cover 8 and the device housing 1, the sealing effect can be achieved. And by unscrewing the fixing bolt 81, the fixed cover 8 can be disassembled, which is convenient for maintaining the internal parts. Through the installation pipe 83, an external air compression device can convey compressed air into the device housing 1 and blow it out from the inside to the outside of the second fine filter cartridge 32, so as to blow out the impurities blocked on the first fine filter cartridge 31, the second fine filter cartridge 32 and the upper baffle of the coarse filter cartridge 3, making the impurities fall into the collection member 6 for collection.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
