Description

Technical Field

[0001] The present application relates to the field of waste gas treatment technologies, and particularly to a paint waste gas treatment device. Background Art

[0002] Paint is a coating applied to the surface of an object to be protected or decorated, and can form a continuous film that adheres firmly to the object to be coated. During the production process of paint, waste gas containing a large amount of dust particles is easily generated. Direct emission will cause serious pollution to the atmospheric environment. Therefore, it is necessary to treat the waste gas before emission.

[0003] The waste gas is transported into each treatment device through a transport pipeline. After the waste gas enters the treatment device, it often concentrates at the position of the outlet of the transport pipeline, so that the waste gas cannot fully contact the filter component inside the treatment device, resulting in poor treatment effect of the waste gas, and the filter component is easily blocked by dust particles, thereby reducing the treatment efficiency of the waste gas.

[0004] Regarding the above related technologies, the inventor believes that the waste gas does not fully contact the filter component, resulting in poor treatment effect of the waste gas and easy blockage of the filter component. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a paint waste gas treatment device.

[0006] The paint waste gas treatment device provided by the present application adopts the following technical solutions:

[0007] A paint waste gas treatment device includes a filter box, an air inlet pipe, an air outlet pipe, a filter component arranged in the filter box, a dust removal component connected to the filter component, a flow equalization component, and a dust removal pipe; the air inlet pipe and the air outlet pipe are both communicated with the filter box, the filter component is arranged between the air inlet pipe and the air outlet pipe, the flow equalization component includes a flow equalization shell communicated with the air inlet pipe, and a plurality of flow equalization pipes are uniformly arranged at one end of the flow equalization shell away from the air inlet pipe, and the flow equalization pipes are communicated with the flow equalization shell, and the filter component includes a filter plate in a stepped structure.

[0008] By adopting the above technical solutions, the waste gas is transported into the flow equalization shell through the air inlet pipe, and then the waste gas is dispersed into the filter box through a plurality of flow equalization pipes. The dispersed waste gas is filtered through the filter plate in a stepped structure. The dispersed waste gas fully contacts the filter plate, improving the filtering efficiency and effect of the waste gas. The filter plate in a stepped structure increases the effective filtering area, thereby further improving the filtering efficiency of the waste gas. The dust removal component cleans the dust particles accumulated on the filter plate, reducing the phenomenon of blockage of the filter net, thereby further improving the filtering efficiency of the waste gas.

[0009] Preferably, the diameter of the flow equalizing pipe close to the intake pipe is smaller than that of the flow equalizing pipe far from the intake pipe.

[0010] By adopting the above technical solution, the resistance of the exhaust gas entering the flow equalizing pipe with a small diameter is relatively large. Therefore, it promotes the flow of the exhaust gas in the flow equalizing shell into the flow equalizing pipe far from the intake pipe, which is beneficial to improving the dispersion effect of the exhaust gas, and further beneficial to enhancing the sufficient degree of contact between the exhaust gas and the filter plate.

[0011] Preferably, a flow resistance component is arranged in the flow equalizing pipe close to the intake pipe.

[0012] By adopting the above technical solution, the setting of the flow resistance component further increases the resistance of the exhaust gas entering the flow equalizing pipe close to the intake pipe, thereby further improving the dispersion effect of the flow equalizing component on the exhaust gas.

[0013] Preferably, the flow resistance component includes flow resistance rods arranged in the flow equalizing pipe, and the two flow resistance rods are arranged crosswise.

[0014] By adopting the above technical solution, the crosswise arranged flow resistance rods reduce the ventilation area of the flow equalizing pipe, which is beneficial to improving the dispersion degree of the gas.

[0015] Preferably, a limiting sliding groove is formed on the inner wall of the filter box. The dust removal component includes a driving motor connected to the filter box, a cam fixedly connected to the transmission shaft of the driving motor, and a return spring arranged in the limiting sliding groove. The cam abuts against the filter plate, the filter plate is slidably connected to the limiting sliding groove, one end of the return spring is connected to the filter plate, and the other end is connected to the filter box.

[0016] By adopting the above technical solution, the driving motor drives the cam to rotate. The cam and the return spring drive the filter plate to move reciprocally, thereby forming vibration to shake off the dust particles accumulated on the filter plate, and further realizing the cleaning of the filter plate.

[0017] Preferably, a sealing gasket is arranged on the side surface of the filter plate close to the inner wall of the filter box, and the sealing gasket abuts against the inner wall of the filter box.

[0018] By adopting the above technical solution, the setting of the sealing gasket increases the tightness of the connection between the filter plate and the filter box, reduces the situation that the exhaust gas is discharged from the filter box without being filtered by the filter plate, and thus improves the filtering effect on the exhaust gas.

[0019] Preferably, the dust removal pipe is arranged below the filter plate. One end of the dust removal pipe close to the filter box is provided with a dust removal inclined surface, and a valve is arranged on the dust removal pipe.

[0020] By adopting the above technical solution, the provision of the dust removal inclined plane facilitates the sliding of the dust particles shaken off by the filter plate into the dust removal pipe. When it is necessary to clean the dust particles, opening the valve can discharge the dust particles from the filter box.

[0021] Preferably, a wind guiding plate is arranged in the filter box. The wind guiding plate is arranged between the flow equalizing component and the dust removal pipe. The wind guiding plate is inclined, and one end of the wind guiding plate far from the inner wall of the filter box inclines in the direction away from the flow equalizing component.

[0022] By adopting the above technical solution, the inclined wind guiding plate guides the waste gas, reducing the phenomenon that the waste gas blows the dust particles falling into the dust removal pipe, thereby reducing the phenomenon that the dust particles are re-brought onto the filter plate, and further improving the dust removal effect on the filter plate.

[0023] In summary, the present application has the following beneficial technical effects:

[0024] 1. The present application adopts a flow equalizing component to disperse and process the waste gas, enabling the waste gas to fully contact the filter plate, thereby improving the filtering effect and efficiency of the waste gas. By arranging a flow blocking rod in the flow equalizing pipe, the dispersion effect on the waste gas is improved, further enhancing the filtering effect and efficiency of the waste gas;

[0025] 2. The stepped filter plate increases the effective filtering area of the waste gas, improves the filtering effect and efficiency of the waste gas, and the stepped filter plate promotes the natural sedimentation of the dust particles, thereby reducing the phenomenon of filter plate blockage and further enhancing the filtering efficiency of the waste gas;

[0026] 3. The dust removal component drives the filter plate to reciprocate through a cam and a return spring, thereby forming vibrations to shake off the dust particles, and further realizing the cleaning of the filter plate, further enhancing the filtering efficiency and effect of the waste gas.

[0032] The following further describes the present application in conjunction with the Figures 1-4 accompanying drawings.

[0033] An embodiment of the present application discloses a coating waste gas treatment device.

[0034] Referring to Figure 1 and Figure 2 , a coating waste gas treatment device includes a filter box 1, an air inlet pipe 11, an air outlet pipe 12, a filter assembly 2 disposed in the filter box 1, a dust removal assembly 3 connected to the filter assembly 2, a flow equalizing assembly 4, and a dust removal pipe 5. The air inlet pipe 11 and the air outlet pipe 12 are both fixedly communicated with the filter box 1. The filter assembly 2 is disposed between the air inlet pipe 11 and the air outlet pipe 12. The flow equalizing assembly 4 includes a flow equalizing housing 41 fixedly communicated with the air inlet pipe 11. A plurality of flow equalizing pipes 42 are uniformly disposed at one end of the flow equalizing housing 41 away from the air inlet pipe 11. The flow equalizing pipes 42 are fixedly communicated with the flow equalizing housing 41. The filter assembly 2 includes a filter plate 21 having a stepped structure. The filter box 1 is fixedly connected with a support rod 13.

[0035] The dust removal pipe 5 is disposed below the filter plate 21. The dust removal pipe 5 is fixedly communicated with the filter box 1. A dust removal inclined plane 51 is disposed at one end of the dust removal pipe 5 close to the filter box 1. A valve 52 is fixedly disposed on the dust removal pipe 5. An air guiding plate 6 is fixedly disposed in the filter box 1. The air guiding plate 6 is disposed between the flow equalizing assembly 4 and the dust removal pipe 5. The air guiding plate 6 is inclined. One end of the air guiding plate 6 away from the inner wall of the filter box 1 is inclined in a direction away from the flow equalizing assembly 4.

[0036] A limit chute 14 is opened on the inner wall of the filter box 1. The dust removal assembly 3 includes a driving motor 31 fixedly connected to the filter box 1, a cam 32 fixedly connected to the transmission shaft of the driving motor 31, and a return spring 33 disposed in the limit chute 14. The cam 32 abuts against the filter plate 21. The filter plate 21 is slidably connected to the limit chute 14. One end of the return spring 33 is fixedly connected to the filter plate 21, and the other end is fixedly connected to the filter box 1. A sealing gasket 22 is fixedly disposed on the side surface of the filter plate 21 close to the inner wall of the filter box 1. The sealing gasket 22 abuts against the inner wall of the filter box 1.

[0037] Referring to Figure 3 and Figure 4, the diameter of the flow equalizing pipe 42 close to the intake pipe 11 is smaller than that of the flow equalizing pipe 42 far from the intake pipe 11. A flow blocking assembly 7 is provided in the flow equalizing pipe 42 close to the intake pipe 11. The flow blocking assembly 7 includes a flow blocking rod 71 fixedly arranged in the flow equalizing pipe 42. In the embodiment of the present application, two flow blocking rods 71 are arranged in one flow equalizing pipe 42, and the two flow blocking rods 71 are vertically and crosswise arranged.

[0038] The implementation principle of a paint waste gas treatment device in an embodiment of the present application is as follows: The waste gas enters the flow equalizing shell 41 through the intake pipe 11. The waste gas flows towards the flow equalizing pipe 42 far from the intake pipe 11 under the flow blocking action of the flow blocking rod 71, so that the waste gas flows to the flow equalizing pipes 42 at different positions and is fully dispersed through the flow equalizing pipes 42. The dispersed waste gas enters the filter box 1 and comes into full contact with the filter plate 21 to achieve efficient filtration. The stepped filter plate 21 increases the effective filtration area of the waste gas, so that the dust particles in the waste gas are fully intercepted and adsorbed, thereby improving the filtration efficiency and effect of the waste gas. At the same time, the stepped filter plate 21 is beneficial to promoting the natural settlement of the dust particles, thereby reducing the phenomenon of blockage of the filter plate 21. When the filter plate 21 needs to be cleaned, the driving motor 31 drives the cam 32 to rotate, and the cam 32 and the return spring 33 drive the filter plate 21 to reciprocate, thereby forming vibration and shaking off the dust particles on the filter plate 21. The dust particles fall on the dust removal inclined surface 51 and then slide into the dust removal pipe 5. The air guiding plate 6 protects the dust particles falling into the dust removal pipe 5 and reduces the phenomenon that the waste gas brings the falling dust particles back to the filter plate 21, thereby improving the dust removal effect of the filter plate 21. Opening the valve 52 can discharge the dust particles from the filter box 1.

[0039] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
