DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example

[0028] like Figure 1-3 As shown, the utility model provides a waste gas purification device for paint production, including: a device bin 1, a collecting tank 2, and a purification mechanism 3. The front end of the device bin 1 is provided with an inlet 100, and the rear end is provided with an outlet 110. The collecting tank 2 is provided at the outlet 110 of the device bin 1, and the purification mechanism 3 is provided on the collecting tank 2. The purification mechanism 3 includes: a filter box 300, a suction fan 310, a filter plate 320, and a first spray rod. The filter box 300 is transverse to the collecting tank 2. A plurality of suction ports 301 are provided on the side of the filter box 300 close to the inlet 100; an openable and closable sewage outlet 302 is provided at the bottom of the filter box 300, the suction fan 310 is connected to the side of the filter box 300 away from the suction port 301, and the filter plates 320 are arranged at intervals in the filter box 300. The first spray rod is provided at the top of the filter box 300, and the water outlet of the first spray rod is aligned with the filter plate 320. The sewage outlet 302 is closed, and the filter box 300 is a sealed structure. When using the device, the operator walks into the device warehouse 1 through the entrance 100 and starts the suction fan 310. The operator sprays paint on the objects to be painted at the front end of the purification mechanism 3. The paint mist and other waste gases generated by the paint spraying are directed toward the purification mechanism 3. The suction port 301 sucks the waste gas into the filter box 300. The filter box 300 is provided with a filter plate 320 and a first spray rod, which can collect the waste gas collected in the filter box 300 through water. The paint will form a thin film on the surface of the water. By opening the sewage outlet 302, the waste water in the filter box 300 enters the collection tank 2, and the paint film on the upper surface of the water in the collection tank 2 is cleaned in time. The device can purify the waste gas generated during the painting process.

[0029] In this embodiment, the bottom of the filter box 300 is configured as a concave structure. A plurality of baffles are spaced along the upper edge of the concave structure. The bottom surfaces of the filter plates 320 contact the baffles. A plurality of slide rails 303 are provided on the top of the filter box 300. The upper edges of the filter plates 320 can pass through the slide rails 303 and enter the filter box 300. The slide rails 303 facilitate the spacing of the filter plates 320. An opening window 304 is provided on one side of the filter box 300. A sealing strip is provided along the edge of the opening window 304. The opening window 304 allows the filter plates 320 to be removed by opening the opening window 304 when it is necessary to replace them. The sealing strip of the opening window 304 ensures that, when the sewage outlet 302 and the opening window 304 remain closed, the suction port 301 can improve the efficiency of exhaust gas absorption when the suction fan 310 is activated.

[0030] In this embodiment, a plurality of air suction ports 301 on the filter box 300 are evenly spaced at the edge of the filter box 300. A connecting block extends from one side of the filter box 300 provided with the air suction ports 301. The connecting block is connected to a water curtain mechanism 4. The water curtain mechanism 4 includes: a connecting seat 400, a second spray bar 410, and a nozzle 420. One side of the connecting seat 400 is connected to the connecting block. Support seats are provided at both ends of the connecting seat 400. Both ends of the second spray bar 410 are provided on two support seats. One end of the second spray bar 410 is externally connected to pressurized water. Each nozzle 420 is connected to the lower surface of the second spray bar 410. Preferably, the water curtain mechanism 4 is detachably provided on the filter box 300. The water curtain mechanism 4 can set a water curtain in front of the filter box 300 to preliminarily absorb waste gas such as paint mist. The water curtain generated by the second spray bar 410 can fall into the collection tank 2.

[0031] It should be noted that in order to further save water resources, a drain pipe is preferably provided on the side of the collection tank 2 near the bottom, the drain pipe is connected to the water pump, and the water pump is connected to the second spray rod 410. When a certain height of water accumulates in the collection tank 2, the pressure water is turned off and the water pump is started so that the water in the collection tank 2 can form a water curtain through the second spray rod 410 again. Since a paint film will form on the upper surface of the water in the collection tank 2 and paint residue will accumulate at the bottom, opening a drain pipe on the side of the collection tank 2 near the bottom can obtain water with relatively fewer impurities.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
