Description

Technical Field

[0002] With the rapid development of industrialization, paint spraying rooms, as an indispensable part of modern industrial production, have become increasingly prominent in terms of waste gas emissions. During the painting process, the organic solvents in the paint evaporate at high temperatures to form a large amount of volatile organic compounds. These substances not only pose a serious threat to human health, but also cause serious pollution to the environment. Therefore, the research and development and application of waste gas treatment mechanisms in paint spraying rooms are particularly important.

[0003] In the existing technology, the traditional exhaust gas treatment mechanism of the paint spraying room usually adopts the method of sucking out the indoor exhaust gas and filtering it through the filter net fixed in the filter box, and then discharging the treated exhaust gas to the outside. However, the filter net is usually fixed in the filter box and cannot be disassembled and replaced. As time goes by and the exhaust gas treatment continues, the pollutants on the filter net gradually accumulate, resulting in the filtering effect of the filter net gradually decreasing, which not only affects the efficiency of the exhaust gas treatment, but may also cause the exhaust gas treatment emission quality to fail to meet the standards, causing pollution to the environment.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-Figure 5As shown, the utility model provides an exhaust gas treatment mechanism for a paint spraying room, comprising a paint spraying room body 1, the outer surface of the paint spraying room body 1 is provided with a filter disassembly mechanism 2, the top of the paint spraying room body 1 is provided with a spraying mechanism 3, the filter disassembly mechanism 2 comprises a mounting plate 201 and a first air pump 203, a plurality of dust suction heads 202 are fixedly installed at an equal distance on the bottom of the mounting plate 201, the top of the mounting plate 201 is fixedly connected to the inner top of the paint spraying room body 1, the first air pump 203 is installed on the top of the paint spraying room body 1, the outer surface of the first air pump 203 is provided with a first ventilation duct 204, one end of the first ventilation duct 204 is provided with a filter box 205, the outer surfaces of both sides of the filter box 205 are provided with connecting grooves 206, the first air pump 203 is connected to the dust suction head 202, and the inner surface wall of the filter box 205 is slidably connected to two filter boxes. Filter plate 207, triangular grooves 208 are provided on the outer surfaces of both sides of the two filter plates 207, and the inner walls of the multiple triangular grooves 208 are provided with triangular blocks 209. The outer surfaces of the multiple triangular blocks 209 are fixedly connected with connecting rods 210, and the outsides of the multiple connecting rods 210 are provided with springs 211. The inner walls of the multiple connecting grooves 206 are fixedly connected with fixed plates 212, and the outer surfaces of the multiple connecting rods 210 are slidingly connected to the inner walls of the fixed plates 212. The bottom of the filter box 205 is fixedly connected to the second ventilation duct 213, and the outer surface of the second ventilation duct 213 is provided with a second air pump 214. The bottom of the second air pump 214 is provided with a base 215. The outer surface of the base 215 is fixedly connected to the outer surface of the paint spraying room body 1, and the outer surface of the filter box 205 is fixedly installed to the outer surface of the paint spraying room body 1.

[0024] The effect achieved by the entire embodiment 1 is that, when in use, the first air pump 203 is first started, and the exhaust gas in the room is sucked into the first ventilation duct 204 through the dust suction head 202 under the mounting plate 201, and then transported to the filter box 205 through the first ventilation duct 204. At this time, the filter plate 207 in the filter box 205 will filter the exhaust gas. The filter plate 207 is made of paint-blocking cotton and activated carbon respectively. The paint-blocking cotton effectively captures the paint mist in the exhaust gas and reduces the particulate matter in the exhaust gas through its special fiber structure and surface characteristics, and the activated carbon has adsorption capacity and can effectively adsorb organic matter in the exhaust gas. Then the second air pump 214 is started, and the filtered air is discharged through the second ventilation duct 213. When the filter plate needs to be cleaned or replaced due to long-term use, the triangular block 209 restricted on the filter plate is separated from the triangular groove 208 by pulling the connecting rods 210 on both sides. When the triangular block 209 is removed from the triangular groove 208, When the filter plate 207 is removed from the filter box 205, the block 209 is disengaged from the triangular groove 208, so that the filter plate 207 can be taken out of the filter box 205. After the filter plate 207 is taken out, it is cleaned to remove the accumulated pollutants and restore its filtering effect. After cleaning is completed, the cleaned filter plate 207 is put into the filter box 205 again. During the loading process, as the filter plate 207 slides, it will gradually squeeze the triangular block 209. At this time, under the action of the spring 211, the triangular block 209 enters the connecting groove 206. When the triangular block 209 contacts the triangular groove 208, the spring 211 will immediately return to its original shape, ensuring that the triangular block 209 is in the groove, providing the necessary restriction for the filter plate 207. Under the action of the filter disassembly mechanism 2, the filter screen can be disassembled and cleaned to avoid the accumulation of pollutants on the filter screen and the reduction of the filtering effect, thereby ensuring the efficiency of the exhaust gas treatment, ensuring that the exhaust gas treatment meets the standards, and reducing the pollution to the environment.

[0025] Example 2, as Figure 1-Figure 5 As shown, the spraying mechanism 3 includes a liquid storage tank 301, a liquid delivery pipe 302 is provided on the outer surface of the liquid storage tank 301, a connecting plate 303 is provided at one end of the liquid delivery pipe 302, a plurality of mist nozzles 304 are fixedly installed on the bottom of the connecting plate 303, a water pump 305 is provided on the outer surface of the liquid delivery pipe 302, and the bottom of the liquid storage tank 301 is fixedly installed on the top of the paint spraying room body 1.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, first add appropriate air freshener to the liquid storage tank 301. When the exhaust gas is discharged from the room, start the water pump 305, and draw the air freshener in the liquid storage tank 301 through the infusion pipe 302 and transport it to the mist nozzle 304 at the bottom of the connecting plate 303. The air freshener is sprayed in the form of mist through the mist nozzle 304. Under the action of the spraying mechanism 3, the air freshener can be sprayed into the room, further preventing the residual paint smell in the room, thereby protecting the health of the staff.

[0027] Working principle: When in use, first start the first air pump 203, and suck the indoor exhaust gas into the first ventilation duct 204 through the dust collector head 202 and transport it to the filter box 205. At this time, the filter plate 207 in the filter box 205 will filter the exhaust gas, and then start the second air pump 214 to discharge the filtered air through the second ventilation duct 213. When cleaning or replacing the filter plate, pull the connecting rods 210 on both sides to disengage the triangular block 209 from the triangular groove 208. When the triangular block 209 is out of the triangular groove 208, the filter plate 207 can be taken out of the filter box 205. After taking out the filter plate 207, clean it. Finally, the cleaned filter plate 207 is loaded into the filter box 205 again. During the loading process, as the filter plate 207 slides, it will gradually squeeze the triangular block 209. At this time, under the action of the spring 211, the triangular block 209 enters the connecting groove 206. When the triangular block 209 contacts the triangular groove 208, the spring 211 will immediately return to its original shape, ensuring that the triangular block 209 is in the groove, providing necessary restrictions for the filter plate 207. By starting the water pump 305, the air freshener in the liquid storage tank 301 is extracted through the infusion pipe 302 and transported to the mist nozzle 304 at the bottom of the connecting plate 303, and the air cleanser is sprayed out in the form of mist through the mist nozzle 304.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
