Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to environmentally friendly waste gas treatment equipment for coatings. Background Technology

[0002] During the production and application of paints, waste gases containing particulate matter (such as paint mist, pigment and filler particles), water-soluble VOCs (such as alcohols and amines), and some gaseous pollutants are generated. Direct emission of these gases will cause air pollution, harming the environment and human health. Currently, the pretreatment of such waste gases often employs spray absorption, which involves contacting the treated liquid with the waste gas to capture particulate matter and absorb soluble pollutants. This is a commonly used, economical, and efficient technology in environmental waste gas treatment.

[0003] However, existing spray absorption equipment has certain shortcomings in long-term use: the treated liquid after spraying needs to be filtered through a filter plate to separate impurities, but particulate matter and undissolved paint residue in the exhaust gas easily adhere to the filter pores, causing them to gradually become clogged. Clogged pores hinder the downward flow of the treated liquid, reducing spray circulation efficiency; they also increase the upward resistance of the exhaust gas, affecting the contact between the exhaust gas and the treated liquid, leading to a decrease in purification efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an environmentally friendly waste gas treatment device for coatings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The paint coating environmental waste gas treatment equipment includes a suction hood and a treatment tank, wherein the suction hood is connected to the treatment tank via a gas supply pipe, and further includes: The filter plate is fixedly connected in the treatment tank; An infusion pipe is fixedly connected to the top of the treatment tank, and a spray pipe is fixedly connected to the bottom of the infusion pipe. The spray pipe is located directly above the filter plate. A slide bar is fixedly connected in the processing tank, and the slide bar is fixedly connected to the filter plate; A float plate is slidably connected to a slide rod, and multiple sets of top rods are fixedly connected to the float plate. The multiple sets of top rods are located directly below the filter holes on the filter plate.

[0006] Preferably, the top of the float plate has a liquid guiding slope.

[0007] Preferably, the processing tank is provided with an installation groove, and a baffle is detachably connected to the installation groove, the baffle being located above the filter plate.

[0008] Preferably, a first magnet is fixedly connected to the processing tank, and a second magnet is fixedly connected to the baffle, wherein the first magnet and the second magnet attract each other.

[0009] Furthermore, a handle is fixedly connected to the baffle.

[0010] Furthermore, both the first magnet and the second magnet are strong magnets.

[0011] Compared with the prior art, this utility model provides an environmentally friendly waste gas treatment device for coatings, which has the following beneficial effects: 1. This utility model, through the cooperative structure of a float plate, a top rod, and a filter plate, allows the float plate to rise with the liquid level when the liquid accumulation at the bottom of the treatment tank increases. This causes the top rod to insert into the filter holes of the filter plate, pushing the impurities blocked in the filter holes back to the surface of the filter plate. This achieves automatic unblocking of the filter holes, effectively avoiding the problems of poor flow of the treatment liquid and increased resistance of the exhaust gas caused by filter hole blockage. It ensures the continuous and stable operation of the equipment and improves the continuity of exhaust gas treatment.

[0012] 2. This utility model achieves detachable connection of the baffle through magnetic adsorption. Workers can quickly remove the baffle using the handle to clean impurities from the filter plate surface, making operation simple and convenient. Simultaneously, the inclined design of the float plate guides the treated liquid to quickly slide to the bottom, reducing liquid residue accumulation and lowering the difficulty of cleaning the inside of the equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1: Reference Figures 1-5 The environmental protection waste gas treatment equipment for coatings includes an air suction hood 1 and a treatment tank 2. The air suction hood 1 is connected to the treatment tank 2 through an air supply pipe 201. It also includes: Filter plate 206 is fixedly connected in processing tank 2; A liquid infusion pipe 202 is fixedly connected to the top of the treatment tank 2, and a spray pipe 2021 is fixedly connected to the bottom of the liquid infusion pipe 202. The spray pipe 2021 is located directly above the filter plate 206. The slide bar 207 is fixedly connected in the processing tank 2, and the slide bar 207 is fixedly connected to the filter plate 206; The float plate 208 is slidably connected to the slide rod 207. Multiple sets of top rods 2081 are fixedly connected to the float plate 208, and the multiple sets of top rods 2081 are located directly below the filter holes on the filter plate 206.

[0017] The top of the float plate 208 has a liquid guiding slope.

[0018] Reference Figure 5 An exhaust pipe 203 and a drain pipe 204 are fixedly connected to the side wall of the treatment tank 2. The drain pipe 204 is located below the filter plate 206.

[0019] Reference Figure 5 The end of the gas supply pipe 201 away from the suction hood 1 is fixedly connected to the bottom of the processing tank 2, and there is a gap between the gas supply pipe 201 and the bottom of the floating plate 208 at the connection part between the gas supply pipe 201 and the processing tank 2, so as to ensure that the gas can be stably input into the processing tank 2 when the gas supply pipe 201 is supplying gas.

[0020] When in use, the suction hood 1 draws the waste gas to be treated into the treatment tank 2 and simultaneously through the liquid inlet pipe 202. At this time, the liquid inlet pipe 202 sprays the treatment liquid into the treatment tank 2 through the spray pipe 2021. The treatment liquid will come into contact with the waste gas input into the treatment tank 2 and react, thereby effectively absorbing particulate matter and gaseous pollutants in the waste gas.

[0021] During processing, the sprayed treatment liquid flows through the filter plate 206 and into the bottom of the treatment tank 2. As the treatment liquid at the bottom of the treatment tank 2 gradually increases, the float plate 208 will slide upward. The upward movement of the float plate 208 will push the top rod 2081 upward in sync. After the float plate 208 has floated a certain distance, the top rod 2081 will be inserted into the filter holes on the filter plate 206 in the opposite direction, thereby pushing the impurities that may be blocked in the filter holes onto the surface of the filter plate 206. At this time, the operator can stop the gas supply pipe 201 and stop the liquid supply pipe 202 from supplying treatment liquid. Then, manually opening the baffle 3 can effectively push out the impurities pushed onto the filter plate 206, solving the problem of long-term blockage of the filter holes on the filter plate 206 and affecting the filtration of exhaust gas.

[0022] It should be noted that, in practice, after the staff manually cleans the impurities on the filter plate 206, they can manually open the valve on the drain pipe 204. At this time, the treatment liquid in the treatment tank 2 can be discharged through the drain pipe 204. After the treatment liquid is discharged, the float plate 208 will slide down and reset under its own weight and the weight of the top rod 2081.

[0023] After the treatment liquid in the treatment tank 2 is fully discharged, the waste gas can be extracted again through the gas supply pipe 201, and then the liquid can be supplied and sprayed again through the liquid supply pipe 202 to treat the extracted waste gas again.

[0024] Reference Figure 5 The liquid is guided by the inclined surface on the float 208, which facilitates the liquid to slide down quickly when it flows through the float 208 and then be discharged through the drain pipe 204.

[0025] The treatment tank 2 has an installation groove 205, and a baffle 3 is detachably connected to the installation groove 205. The baffle 3 is located above the filter plate 206.

[0026] A first magnet 209 is fixedly connected to the processing tank 2, and a second magnet 302 is fixedly connected to the baffle 3. The first magnet 209 and the second magnet 302 attract each other.

[0027] Reference Figure 3 , Figure 4 When the baffle 3 is installed, the second magnet 302 on the baffle 3 will attract the first magnet 209 on the processing tank 2. The attraction between the first magnet 209 and the second magnet 302 can effectively ensure the installation stability of the baffle 3 and prevent the baffle 3 from falling off during the processing.

[0028] It should be noted that, in order to ensure the sealing of the connection between the baffle 3 and the treatment tank 2 during implementation, a sealing ring can also be set in the mounting groove 205, and when the baffle 3 is installed in the mounting groove 205, the sealing ring and the baffle 3 are in contact.

[0029] A handle 301 is fixedly connected to the baffle 3.

[0030] Reference Figure 2 , Figure 3 The handle 301 installed on the baffle 3 makes it easy for staff to pull the baffle 3.

[0031] Both the first magnet 209 and the second magnet 302 are strong magnets.

[0032] By setting the first magnet 209 and the second magnet 302 as strong magnets, the installation stability of the baffle 3 can be further improved, preventing the baffle 3 from falling off after installation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
