[0041] The flow guiding component 4 includes a water guide frame 42, in which water baffles 41 are evenly arranged inside, and a drain outlet 43 is provided on the bottom side of the water guide frame 42.

[0042] The water inlet 11 is aligned with the groove 110 via the bottom water guide pipe 19, allowing the filtered water inside the filter chamber 111 to be drawn for recycling under the action of an external water pump. The drive motor 15 is connected to one end of the drive shaft 12 via a helical gear 14, thereby controlling the rotation of the drive shaft 12. Fastening screws are attached to the outer surface of the conveyor belt 18. The cleaning plate 32 is fastened to the fastening screws on the outer surface of the conveyor belt 18 via threaded holes 33, ensuring the stability of the connection between the cleaning plate 32 and the conveyor belt 18. The bottom of the cleaning plate 32 slides against the inner surface of the wedge-shaped filter plate 17, enabling... When the cleaning plate 32 slides, it scrapes away the paint residue on the surface of the wedge-shaped filter plate 17. The cleaning shaft 36 is connected to the transmission gear 112 on the inner surface of the wedge-shaped filter plate 17 through the transmission gear 35. When the cleaning plate 32 slides, it can drive the cleaning shaft 36 to rotate and clean the wedge-shaped filter plate 17. The cleaning plate 32 is slidably engaged with the drain outlet 43 through the water-blocking slide strip 31, which can block the drain outlet 43 corresponding to the position where the cleaning plate 32 moves. The connection point between the outer surface of the water-blocking slide strip 31 and the cleaning plate 32 is 7:3, with the shorter dimension on the side closer to the cleaning shaft 36, to prevent water flow from washing away the scraping surface of the cleaning plate 32.

[0043] The drain outlet 43 at the bottom of the guide component 4 is parallel to the conveyor belt 18, allowing the water-blocking slide strip 31 to slide back and forth normally driven by the slag-cleaning plate 32.

[0044] A method for treating and purifying paint mist in a spray painting workshop includes:

[0045] Step one, first install the purification device in the paint spray workshop paint mist water curtain cabinet behind the bottom, and make the water curtain cabinet extraction paint mist water through the flow member 4 discharge to the inside of the wedge-shaped filter plate 17;

[0046] Step two, control the drive motor 15 through the transmission shaft 12 and transmission belt 18 drive cleaning component 3 in the inside of the wedge-shaped filter plate 17 sliding, scraping the wedge-shaped filter plate 17 filtered paint slag, and the wedge-shaped filter plate 17 itself is in an inclined state, can avoid the unfiltered paint water overflow to the inside of the collection component 2;

[0047] Step three, the cleaning component 3 will deliver the paint slag to the inside of the collection component 2 for collection, and the slag removal plate 32 will drive the cleaning shaft 36 to clean the surface of the wedge-shaped filter plate 17, to ensure the normal filtration of the inside of the wedge-shaped filter plate 17, wherein the slag removal plate 32 moves, drives the water blocking slide 31 to slide outside the drain port 43, thereby cutting off the water at the slag removal position of the slag removal plate 32.

[0048] The working principle of the present application: first, connect the purification device with the paint spray workshop paint mist water curtain cabinet behind the bottom, and make the water curtain cabinet extraction paint mist water through the flow member 4 discharge to the inside of the wedge-shaped filter plate 17, the wedge-shaped filter plate 17 will filter the paint slag, because the wedge-shaped filter plate 17 is in an inclined state in the inside of the water tank 16, the paint water discharged from the drain port 43 will not overflow to the inside of the collection component 2, and in the long-term filtration of the wedge-shaped filter plate 17 to the paint water, the paint slag in the inside of the wedge-shaped filter plate 17 needs to be cleaned, first start the drive motor 15 to run, and drive the transmission shaft 12 to rotate through the bottom bevel gear 14, at the same time, the transmission shaft 12 will drive the outer surface of the transmission belt 18 to drive the outer surface of the slag removal plate 32 to slide in the inside of the wedge-shaped filter plate 17, because the outer periphery of the bottom of the slag removal plate 32 is adapted to abut against the inner surface of the wedge-shaped filter plate 17, the slag removal plate 32 slides in the inside of the wedge-shaped filter plate 17, which will scrape off the paint slag filtered by the wedge-shaped filter plate 17, and the wedge-shaped filter plate 17 itself is in an inclined state, the transmission belt 18 will drive the slag removal plate 32 to move from the bottom end to the highest end of the wedge-shaped filter plate 17, and with the mechanical rotation of the transmission belt 18, the slag removal plate 32 will deflect the scraped paint slag upward, and finally the upward deflected surface of the slag removal plate 32 will contact the slag scraping plate 25, and with the continuous upward turning of the slag removal plate 32, the slag scraping plate 25 will be pressed to deflect upward, and the second traction spring 27 will pull the slag scraping plate 25 to reset, so that the slag scraping plate 25 will scrape off the paint slag adhered to the surface of the slag removal plate 32, so that the paint slag falls into the inside of the slag collection tank 21 for collection, when the slag removal plate 32 and the slag scraping plate 25 are separated, the second traction spring 27 will pull the limiting strip 26 to reset and vibrate to deflect downward, to ensure that the paint slag falls off;

[0049] The slag removal plate 32 slides inside the wedge-shaped water filter plate 17, and the transmission gear 35 at one end of the cleaning shaft 36 is engaged with the transmission gear slot 112 on the surface of the wedge-shaped water filter plate 17. When the slag removal plate 32 moves inside the wedge-shaped water filter plate 17, the cleaning shaft 36 rotates synchronously, thereby cleaning the inner surface of the wedge-shaped water filter plate 17 and ensuring normal filtration. When the slag removal plate 32 moves, the water-blocking slide 31 slides outside the drain port 43, thereby blocking the water at the slag scraping position of the slag removal plate 32. The water-blocking slide 31 at the end of the slag removal plate 32 in the forward direction blocks the water flow in the forward direction of the slag removal plate 32 in real time, thereby avoiding the impact of the water flow on the paint slag scraped by the slag removal plate 32. When the slag removal plate 32 is deflected along the transmission belt 18, the water-blocking slide 31 is at the center of the transmission belt 18. When the slag removal plate 32 is deflected at the end of the transmission belt 18, the connection point between the slag removal plate 32 and the water-blocking slide 31 is coaxial with the transmission shaft 12. When the slag removal plate 32 is flipped upward and then moves back, the water-blocking slide 31 slides reversely at the end of the drain port 43 until the slag removal plate 32 is flipped downward again and abuts against the inside of the wedge-shaped water filter plate 17, thereby cleaning the paint slag inside the wedge-shaped water filter plate 17. The water-blocking slide 31 is uniformly arranged inside the water guide frame 42, which can make the paint water uniformly drain through the drain port 43 without being affected by the inclined drain port 43. Most of the water flow is drained through the lowest end of the drain port 43. When the inside of the slag collection box 21 is full of paint slag, the end surface of the slag collection box 21 can be separated from the water tank 16. When the inside of the slag collection box 21 needs to be cleaned, the positioning insert 24 can be pulled up to separate the two ends of the positioning insert 24 from the top of the blocking plate 22, and then the blocking plate 22 is flipped. The paint slag in the slag collection box 21 can be removed. Then, the magnetic plate at the end of the slag collection box 21 is aligned with the end of the water tank 16, the end of the slag collection box 21 is attracted and connected to the end of the water tank 16, and the wedge-shaped port 28 is aligned with the end of the wedge-shaped water filter plate 17. Through the cooperation between the filter component 1, the collection component 2, the cleaning component 3, and the flow guide component 4, the paint mist water can be filtered in time, the paint slag can be automatically cleaned, the continuous and normal operation of the paint mist treatment and purification device in the spraying workshop can be ensured, and the labor intensity of the workers is reduced.

[0050] The above describes one embodiment of the present application in detail, but the content is only the preferred embodiment of the present application and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent scope of the present application.

Step 2: Control the drive motor (15) to drive the cleaning component (3) to slide inside the wedge-shaped filter plate (17) through the transmission shaft (12) and the transmission belt (18), scrape off the paint residue filtered by the wedge-shaped filter plate (17), and the wedge-shaped filter plate (17) itself is in an inclined state, which can prevent unfiltered paint from overflowing into the collection component (2). Step 3: The cleaning component (3) will transport the paint residue to the collection component (2) for collection. At the same time, the cleaning plate (32) will drive the cleaning shaft (36) to clean the surface of the wedge filter plate (17) to ensure normal filtration inside the wedge filter plate (17). When the cleaning plate (32) moves, it will drive the water blocking strip (31) to slide outside the drain outlet (43), thereby blocking water at the scraping position of the cleaning plate (32).
