Description

Technical Field

[0001] The present application relates to the technical field of exhaust gas purification devices, and in particular to an exhaust gas purification device for an epoxy powder spraying line. Background Art

[0002] Epoxy powder spraying line is a coating technology that uses epoxy powder as the coating material and evenly applies the powder to the product surface through electrostatic spraying. This technology is mainly used for surface decoration and protection of products. It can effectively improve the beauty and durability of the product and prevent corrosion from natural factors such as sunlight and rain. Simply put, the epoxy powder spraying line uses epoxy powder through electrostatic spraying to "apply a layer of 'mask'" to the product surface to achieve the purpose of beauty and protection. During the coating process, the epoxy powder spraying line will produce a large amount of exhaust gas. In order to avoid the exhaust gas from polluting the working environment, it is often necessary to use an exhaust gas purification device to purify the exhaust gas.

[0003] When the relevant exhaust gas purification device is in use, the exhaust gas generated during the powder spraying process is usually collected by a collection device to prevent the exhaust gas from being directly discharged into the air. The collected exhaust gas is then transported to a closed container, and then the exhaust gas is purified by an exhaust gas dissolution area filled with a dissolving liquid set in the container. The undissolved particles are then filtered through a filter plate, and finally the treated exhaust gas is discharged into the environment to reduce pollution to the working environment.

[0004] However, when using the above-mentioned method, the filter plates often accumulate and clog the filter pores after a long period of filtration due to the accumulation of particles when filtering insoluble particles, thereby affecting the normal filtration of insoluble particles in the exhaust gas and reducing the filtration efficiency. Therefore, those skilled in the art have provided an exhaust gas purification device for an epoxy powder spraying line to solve the problems raised in the above-mentioned background art.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application discloses an exhaust gas purification device for an epoxy powder spraying line. Figure 3 Figure 4 An exhaust gas purification device for an epoxy powder spraying line includes a purification tank 1, a maintenance door 101 is installed on the side wall of the purification tank 1, a gas transmission mechanism 2 for conveying exhaust gas is provided on the side wall of the purification tank 1, a purification mechanism 3 for purifying exhaust gas is provided at the inner bottom end of the purification tank 1, and further includes

[0024] The anti-blocking mechanism 4 is located in the middle of the purification mechanism 3 and is used to scrape and clear the accumulated and blocked particles to prevent blockage;

[0025] The anti-blocking mechanism 4 includes a rotating rod 401, a plurality of first springs 402, a brush rod 403 and a drive assembly 5. The purification mechanism 3 includes a filter plate 302. One end of the rotating rod 401 is mounted on the middle of the filter plate 302 through the drive assembly 5. The plurality of first springs 402 are symmetrically fixedly connected to the inner wall of the rotating rod 401. The brush rod 403 is slidably connected to the top of the rotating rod 401, and the bottom of the brush rod 403 is fixedly connected to the other ends of the plurality of first springs 402.

[0026] The drive assembly 5 includes a motor 501, a support shaft 502, and a fixed block 503. The motor 501 is fixedly connected to the top center of the filter plate 302. One end of the support shaft 502 rotates through the top center of the filter plate 302 and is fixedly connected to the output end of the motor 501. The top of the fixed block 503 is fixedly connected to the other end of the support shaft 502. One end of the rotating rod 401 is fixedly connected to the side wall of the fixed block 503.

[0027] The purification mechanism 3 further includes a dissolving water pool 301, the bottom of which is fixedly connected to the inner bottom end of the purification tank 1, and the side wall of the filter plate 302 is installed on the inner side of the top of the dissolving water pool 301 through the insertion mechanism 6;

[0028] The gas transmission mechanism 2 includes an air inlet pipe 201, a fixing plate 202, an air inlet valve 203, an exhaust pipe 204, and an exhaust valve 205. The side wall of the air inlet pipe 201 is fixedly connected to the side wall of the purification tank 1 through the fixing plate 202, and one end of the air inlet pipe 201 is fixedly connected to the side wall of the dissolving water tank 301 by passing through the side wall of the purification tank 1. The air inlet valve 203 is fixedly connected to the side wall of the air inlet pipe 201, one end of the exhaust pipe 204 is fixedly connected to the top of the purification tank 1, and the exhaust valve 205 is fixedly connected to the side wall of the exhaust pipe 204.

[0029] In this embodiment, first, after the tail gas is collected by the collection device, the intake valve 203 is opened to open the intake pipe 201. At this time, the tail gas collected by the collection device can be transported to the dissolving pool 301 in the purification tank 1 through the opened intake pipe 201. The tail gas can be purified by the dissolved liquid in the dissolving pool 301, and the insoluble particulate matter can be filtered by the filter plate 302. Moreover, after a long period of filtration, the motor 501 is started to provide a force to drive the support shaft 502 connected thereto to rotate at the middle of the filter plate 302. The support shaft 502 rotates to drive the fixed block 50 connected thereto. 3 is subjected to force and rotates with it, and the fixed block 503 rotates to drive the rotating rod 401 to rotate with it, and the first spring 402 provides a force to force the brush rod 403 connected thereto to slide out from the top of the rotating rod 401, and the brush rod 403 slides out to fit the surface of the filter plate 302. At this time, the rotation of the rotating rod 401 can drive the brush rod 403 to rotate with it to scrape and clean the filter holes on the surface of the filter plate 302, so that the filter holes of the filter plate 302 can be automatically scraped and cleaned, thereby effectively preventing the accumulation of particles from clogging the filter holes of the filter plate 302, facilitating normal filtration and improving the filtration efficiency.

[0030] Furthermore, after the purification process, the exhaust pipe 204 can be opened by opening the exhaust valve 205. At this time, the purified exhaust gas can be discharged into the external environment through the opened exhaust pipe 204.

[0031] Among them, it should be noted that the collection device, the dissolved liquid in the dissolving pool 301 and the filter plate 302 in this application all adopt existing technologies. For details, please refer to the exhaust gas treatment equipment of the existing epoxy powder spraying line. Therefore, its working principle will not be described in detail here.

[0032] Furthermore, the insertion mechanism 6 includes two limit plugs 601, two limit sockets 602, and a control component 7. One end of the two limit plugs 601 is mounted on the side wall of the filter plate 302 through the control component 7. The two limit sockets 602 are symmetrically opened on the top inner side of the dissolving water tank 301, and the two limit plugs 601 are matched with the two limit sockets 602.

[0033] The control assembly 7 includes two telescopic slides 701, two second springs 702 and two control slide bars 703. The two telescopic slides 701 are symmetrically arranged on the side walls of the filter plate 302. One end of the two second springs 702 is fixedly connected to one end of the two telescopic slides 701. The two limit plugs 601 are slidably connected to the side walls of the two telescopic slides 701, and one end of the two limit plugs 601 is fixedly connected to the other end of the two second springs 702. The two control slide bars 703 slide through the top of the filter plate 302 and are fixedly connected to the top of the two limit plugs 601.

[0034] Before purifying the exhaust gas on the basis of the above embodiment, the purification tank 1 is opened by opening the inspection door 101 which is hingedly installed or snap-fitted on one side. At this time, the control slide bar 703 is slid to drive the limit plug 601 connected thereto to slide and retract into the telescopic slide groove 701 opened on the side wall of the filter plate 302. Then, the limit plug 601 on the side wall of the filter plate 302 is aligned with the limit socket 602 opened on the side wall of the dissolving water tank 301, and the filter plate 302 is embedded in the top of the dissolving water tank 301. At this time, the control slide bar 703 is released and the force provided by the second spring 702 causes the limit plug 601 to rebound under force. The filter plate 302 is conveniently disassembled by pulling out the filter plate 302 from the top of the dissolving water tank 301. In this way, the filter plate 302 can be conveniently installed and disassembled, thereby facilitating the repair, replacement or maintenance of the filter plate 302, and further facilitating the normal use of the filter plate 302 to filter the insoluble particulate matter in the exhaust gas.

[0035] The implementation principle of the exhaust gas purification device of an epoxy powder spraying line in the embodiment of the present application is as follows: when in use, first, the purification tank 1 is opened by opening the inspection door 101 which is hingedly installed or snap-fitted on one side. At this time, the sliding control slide bar 703 is used to drive the limit plug 601 connected thereto to slide and retract into the telescopic slide groove 701 provided on the side wall of the filter plate 302. Then, the limit plug 601 on the side wall of the filter plate 302 is aligned with the limit socket 602 provided on the side wall of the dissolving pool 301, and the filter plate 302 is embedded in the top of the dissolving pool 301. At this time, the control slide bar 703 is released, and the second spring 702 provides a force to make the limit plug 601 rebound and extend under force. The filter plate 302 is then removed from the top of the water dissolving tank 301 and the filter plate 302 is removed from the top of the water dissolving tank 301. This allows the filter plate 302 to be easily installed and removed. This makes it easier to replace or repair the filter plate 302 and further facilitates the filter plate 302 to filter the insoluble particulate matter in the exhaust gas. Secondly, after the exhaust gas is collected by the collection device, the intake valve 203 is opened to allow the intake gas to enter the water dissolving tank 301. The pipe 201 is opened. At this time, the tail gas collected by the collection device can be transported to the dissolving pool 301 in the purification tank 1 through the opened air inlet pipe 201. The tail gas can be purified by the dissolved liquid in the dissolving pool 301, and the insoluble particulate matter can be filtered through the filter plate 302. Moreover, after a long period of filtration, the motor 501 is started to provide a force to drive the support shaft 502 connected thereto to be forced to rotate in the middle of the filter plate 302. The support shaft 502 rotates, thereby driving the fixed block 503 connected thereto to be forced to follow the rotation. The fixed block 503 rotates, thereby driving the rotating rod 401 to be forced to follow the rotation. In addition, the first spring 402 provides a force to make the brush connected thereto The rod 403 is forced to slide out from the top of the rotating rod 401, and is extended by the brush rod 403 to fit the surface of the filter plate 302. At this time, the rotation of the rotating rod 401 can drive the brush rod 403 to follow the rotation to scrape and clean the filter holes on the surface of the filter plate 302. In this way, the filter holes of the filter plate 302 can be automatically scraped and cleaned, thereby effectively preventing the accumulation of particulate matter from causing the filter holes of the filter plate 302 to become blocked, facilitating normal filtration and improving the filtration efficiency. Finally, the exhaust pipe 204 can be opened by opening the exhaust valve 205. At this time, the purified exhaust gas can be discharged into the external environment through the opened exhaust pipe 204, completing the purification of the exhaust gas.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
