Technical Field

[0001] This utility model relates to the field of paint spraying exhaust gas purification, and in particular to an exhaust gas treatment device for electrophoresis lines in paint spraying workshops. Background Technology

[0002] Electrophoretic coating is a coating technology in which the object to be coated is immersed in a water-soluble paint as the anode (anodic electrophoresis), and a corresponding cathode is provided. A direct current is passed between the two electrodes, and the paint is evenly applied to the object through the physicochemical action generated by the current. During the coating process, water-soluble paints emit a large amount of toxic and harmful gases and atomized dust particles, which affect the physical and mental health of the coating workers. Therefore, there is an urgent need for a waste gas treatment device for electrophoretic lines in paint spraying workshops.

[0004] Existing equipment uses several secondary filter plates for layer-by-layer filtration to remove harmful particulate matter from exhaust gas, but it cannot remove harmful particulate matter that covers and adsorbs on the surface of several secondary filter plates, resulting in a decrease in filtration performance.

[0005] Therefore, it is necessary to provide exhaust gas treatment equipment for electrophoresis lines in paint spraying workshops to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a waste gas treatment device for electrophoresis lines in paint spraying workshops.

[0007] The exhaust gas treatment device for the electrophoresis line in the paint spraying workshop provided by this utility model includes a paint spraying exhaust gas treatment box. A fine screen filter plate is provided on one side of the inside of the paint spraying exhaust gas treatment box, and a coarse screen filter plate is provided on the other side of the inside of the paint spraying exhaust gas treatment box. A dust removal structure is provided on one side of the fine screen filter plate and the coarse screen filter plate, and an air suction structure is provided on one side of the dust removal structure.

[0008] The dust removal structure includes two scrapers respectively placed close to one side of the fine screen filter plate and the coarse screen filter plate. Each scraper has a sleeve fixedly installed on its top. Each sleeve has a bidirectional lead screw inserted inside. Both ends of the bidirectional lead screw are rotatably installed in the paint spray exhaust gas treatment box. The interior of each sleeve is slidably installed in the threaded groove on the corresponding bidirectional lead screw through a rotatably installed arc-shaped guide block. The top of each sleeve is slidably installed in the guide groove on the paint spray exhaust gas treatment box through a fixed guide slider.

[0009] In order to achieve the effect of synchronous rotation, as a waste gas treatment device for electrophoresis line in paint spraying workshop provided by this utility model, preferably, one end of each of the two bidirectional lead screws extends through the paint spraying waste gas treatment box and is fixedly installed with pulleys. A transmission belt is provided between the two pulleys. A number of power fan blades are evenly provided at one end of the right pulley of the two pulleys. Two threaded grooves with opposite directions and connected at both ends are opened on the outside of the two bidirectional lead screws.

[0010] In order to provide power for the gas collection and dust removal processes, the exhaust gas treatment device for the electrophoresis line in the paint spraying workshop provided by this utility model preferably includes an air pump installed on one side inside the paint spraying exhaust gas treatment box. One end of the air pump is provided with an air inlet pipe, and the other end of the air pump passes through the paint spraying exhaust gas treatment box through a fixedly installed exhaust pipe and extends to several power fan blades.

[0011] In order to achieve the effect of collecting surrounding exhaust gas, as a waste gas treatment device for electrophoresis line in paint spraying workshop provided by this utility model, preferably, the end of the paint spraying exhaust gas treatment box away from the air intake structure is provided with an air collection structure.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the exhaust gas treatment device for an electrophoresis line in a paint spraying workshop provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the paint spray exhaust gas treatment box. Figure 3 for Figure 2 The diagram shows the structure of a bidirectional lead screw. Figure 4 for Figure 2 The diagram shows the structure of the box shown. Figure 5 for Figure 1 The schematic diagram of the gas collection structure shown includes a paint spray exhaust gas treatment box 1. A fine screen filter plate 2 is provided on one side of the interior of the paint spray exhaust gas treatment box 1, and a coarse screen filter plate 3 is provided on the other side of the interior of the paint spray exhaust gas treatment box 1. A dust removal structure 4 is provided on one side of the fine screen filter plate 2 and the coarse screen filter plate 3, and an air suction structure 5 is provided on one side of the dust removal structure 4.

[0026] The dust removal structure 4 includes two scrapers 401 that are respectively placed close to one side of the fine screen filter plate 2 and the coarse screen filter plate 3. The top of each scraper 401 is fixedly provided with a sleeve 402. A bidirectional lead screw 403 is inserted into the inside of each sleeve 402. Both ends of the bidirectional lead screw 403 are rotatably installed on the paint spray exhaust gas treatment box 1. The inside of each sleeve 402 is slidably installed on the threaded groove provided on the corresponding bidirectional lead screw 403 through a rotatably provided arc-shaped guide block 404. The top of each sleeve 402 is slidably installed on the guide groove 406 provided on the paint spray exhaust gas treatment box 1 through a fixedly provided guide slider 405.

[0027] It should be noted that: the two bidirectional lead screws 403 rotate, and the two threaded grooves on their outer surfaces that are opposite in direction and connected at both ends drive the arc-shaped guide block 404 to move back and forth, thereby controlling the corresponding sleeve 402 to slide back and forth along the guide groove 406. The two scrapers 401 are powered to scrape off the harmful particulate matter attached to one side of the fine screen filter plate 2 and the coarse screen filter plate 3, thus achieving the purpose of dust removal.

[0028] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, one end of each of the two bidirectional lead screws 403 extends through the paint spray exhaust gas treatment box 1 and is fixedly installed with a pulley 407. A transmission belt is provided between the two pulleys 407. Several power fan blades 408 are evenly provided at one end of the right pulley 407. Two threaded grooves with opposite directions and connected at both ends are opened on the outside of each of the two bidirectional lead screws 403.

[0029] It should be noted that: several power fan blades 408 obtain the kinetic energy of the gas discharged from the exhaust pipe 501, control the corresponding pulley 407 to drive the other pulley 407 to rotate in the same direction, and then control the two bidirectional lead screws 403 to rotate, which facilitates the subsequent dust removal.

[0030] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, the air intake structure 5 includes an air pump 502 located inside the paint spray exhaust gas treatment box 1. One end of the air pump 502 is provided with an air inlet pipe 503, and the other end of the air pump 502 passes through the paint spray exhaust gas treatment box 1 through a fixedly provided exhaust pipe 501 and extends to several power fan blades 408.

[0031] It should be noted that: when the air pump 502 is running, it controls the external gas to move towards the air inlet pipe 503, so that the exhaust gas passes through the fine screen filter plate 2 and the coarse screen filter plate 3 in sequence for filtration. Then the cleaned and purified gas is sprayed through the exhaust pipe 501 onto several power fan blades 408 to provide power for the dust removal structure 4.

[0032] In the specific implementation process, refer to Figure 2 and Figure 5 As shown, a gas collection structure 6 is provided at the end of the paint spray exhaust gas treatment box 1 away from the air intake structure 5. The gas collection structure 6 includes a gas collection pipe 601 that is inserted through and connected to one end of the paint spray exhaust gas treatment box 1. A gas collection hood 602 is inserted at the other end of the gas collection pipe 601. A control handle 603 is fixedly provided on the top of the gas collection hood 602.

[0033] It should be noted that the airflow generated by the air pump 502 is transmitted to the gas collection hood 602, and the control handle 603 controls the position of the gas collection hood 602 to facilitate large-area collection of exhaust gas. The collected exhaust gas is transported to the paint spray exhaust gas treatment box 1 through the gas collection pipe 601 for purification treatment.

[0034] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, each of the four corners of the bottom of the paint spray exhaust gas treatment box 1 is fixedly equipped with a movable roller 7, and two control handles 8 are symmetrically arranged at one end of the paint spray exhaust gas treatment box 1.

[0035] It should be noted that: using two control handles 8 to control four moving rollers 7 to move the paint spray exhaust gas treatment box 1 to a different position improves the equipment's mobility.

[0036] In the specific implementation process, refer to Figure 2 As shown, the fine sieve filter plate 2 is made of activated carbon particles and the coarse sieve filter plate 3 is made of woven fiber.

[0037] It should be noted that: the coarse sieve filter plate 3, made of woven fiber, is used to initially adsorb harmful particles in the exhaust gas, and then the fine sieve filter plate 2, made of activated carbon particles, is used for secondary filtration to completely remove impurities from the exhaust gas.

[0038] The working principle of the exhaust gas treatment device for the electrophoresis line in the paint spraying workshop provided by this utility model is as follows:

[0039] In use, two control handles 8 control four moving rollers 7 to move the paint spray exhaust gas treatment box 1 to any position. The control handle 603 controls the movement of the gas collection hood 602 to the location containing exhaust gas. The air pump 502 is activated, and the resulting suction draws harmful exhaust gas from outside the gas collection hood 602 through the gas collection pipe 601 into the paint spray exhaust gas treatment box 1. The gas then passes through the coarse filter plate 3 and the fine filter plate 2, and is subsequently transported through the exhaust pipe 501 to several powered fan blades 408, where it is discharged. The kinetic energy of the gas discharged from the duct 501 controls the corresponding pulley 407 to drive the other pulley 407 to rotate in the same direction, thereby controlling the two bidirectional lead screws 403 to rotate. The two threaded grooves on the outside of the lead screws, which are in opposite directions and connected at both ends, drive the arc-shaped guide block 404 to move back and forth, thereby controlling the corresponding sleeve 402 to slide back and forth along the guide groove 406. The two scrapers 401 are powered to scrape off the harmful particulate matter attached to one side of the fine screen filter plate 2 and the coarse screen filter plate 3, thus completing the purpose of dust removal.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
