Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine exhaust gas treatment device. Background Technology

[0002] In the coating process of a coating machine, an electrically heated oven is used to dry and cure the coating of paint or adhesive on the material surface. Once coating is complete, the coating machine evenly applies the paint to the material to be treated and then sends it into the electrically heated oven for drying. Existing coating machine electrically heated ovens generate exhaust gases containing harmful substances during operation. These exhaust gases are released into the air, polluting the surrounding working environment and endangering the health of operators.

[0003] In existing technologies, treating coating machine exhaust gas requires filtering particulate matter through a filtration structure. However, after prolonged use, the filter element accumulates a large amount of particulate matter, causing blockage. Replacing the filter element requires stopping the treatment equipment and disassembling and installing the filtration structure, which affects the efficiency of exhaust gas treatment. Therefore, we propose a coating machine exhaust gas treatment device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A coating machine exhaust gas treatment device, such as Figures 1-5 As shown, it includes a tank 1, which is a 3 / 4 cylindrical structure; the tank 1 is equipped with a filter mechanism 2, which can treat the exhaust gas generated during the coating process of the coating machine and the subsequent drying process, thereby preventing the exhaust gas from being directly discharged into the air and causing pollution.

[0028] Specifically, the filtration mechanism 2 includes a drive disc 201, with a mounting bracket 202 fixedly connected to its outer side. The drive disc 201 can rotate inside the tank 1, thereby driving the mounting bracket 202 to rotate, facilitating the switching of the mounting bracket 202's position. An adsorption block 203 is movably connected to the mounting bracket 202, with a support pad 204 fitted over its outer side. The adsorption block 203 is filled with adsorption materials including, but not limited to, activated carbon, absorbent cotton, and polyurethane. The support pad 204 allows for easy installation of the adsorption block 203 onto the mounting bracket 202. Both the support pad 204 and the mounting bracket 202 have wavy protrusions on their sides to improve the stability of the adsorption block 203 installation. A storage rack 205 is fixedly connected to the top of the tank 1. The storage rack 205 allows for temporary storage of adsorption blocks 203 to be replaced, facilitating their installation onto the mounting bracket 202 or the removal of adsorption blocks 203 that have been in long-term use from the mounting bracket 202. A screw 206 is movably connected to the top of the storage rack 205, and a push block is rotatably connected to the bottom of the screw 206. The push block can move along the direction of the screw 206, so that the adsorption block 203 can be moved and replaced by pushing the push block.

[0029] It is worth noting that a filter cartridge 207 is fixedly connected inside the tank 1, and a spray pipe 208 is fixedly connected to the inner wall of the filter cartridge 207. The spray pipe 208 can spray water into the filter cartridge 207, thereby using water to remove easily soluble gases and particulate matter from the exhaust gas. At the same time, the structure of the filter cartridge 207 can collect the sprayed water and use the collected water to perform preliminary treatment on the exhaust gas, thereby improving the exhaust gas treatment effect. A liquid inlet pipe is fixedly connected to the spray pipe 208, and the liquid inlet pipe passes through the tank 1. The liquid inlet pipe structure can provide an external water source to the spray pipe 208.

[0030] Based on this, a baffle 209 is fixedly connected inside the tank 1, and the baffle 209 is fixedly connected to both sides of the filter cartridge 207. The structure of the baffle 209 and the filter cartridge 207 cooperate with each other to divide the interior of the tank 1 into two independent areas, facilitating the initial collection of waste gas and the separation of subsequent treatment steps. An electrocatalytic device is fixedly connected to one side of the tank 1. The electrocatalytic device can electrocatalyze the waste gas. Through the electrochemical reaction on the electrode, the harmful substances in the waste gas undergo oxidation-reduction reactions, thereby converting them into harmless substances. The sprayed water can not only remove particulate matter from the waste gas, but also humidify the waste gas, thereby increasing the generation of hydroxyl radicals during the electrocatalytic process. An exhaust gas pipe 210 is fixedly connected to the top of the tank 1. A turbine fan is connected inside the exhaust gas pipe 210. The turbine fan can provide power to guide the waste gas into the tank 1 and collect it inside the tank 1.

[0031] In addition, an air inlet pipe 212 is fixedly connected to one side of the filter cartridge 207, and an aeration pipe 213 is fixedly connected to the end of the air inlet pipe 212. The two ends of the air inlet pipe 212 are respectively located on the outside and inside of the filter cartridge 207. The air inlet pipe 212 can introduce the waste gas inside the tank 1 into the water of the filter cartridge 207, while the aeration pipe 213 can make the waste gas form microbubbles in the water, improving the contact effect between the waste gas and the water, thereby improving the adsorption of easily soluble gases and particulate matter in the waste gas by the water. An exhaust pipe 214 is fixedly connected to the other side of the filter cartridge 207. The exhaust pipe 214 can guide the waste gas that has undergone spray treatment into the interior of the tank 1, thereby facilitating subsequent electrocatalytic treatment.

[0032] Example 2

[0033] like Figure 1 , Figure 4 , Figure 5 As shown, based on Embodiment 1, the tank 1 is equipped with a sewage discharge mechanism 3, which can discharge sewage from the filter cylinder 207, thereby keeping the water level in the filter cylinder 207 within a preset height range.

[0034] In this embodiment, the sewage discharge mechanism 3 includes a drain pipe 301. One end of the drain pipe 301 passes through the tank body 1 and is located at the bottom of the tank body 1. The drain pipe 301 is connected to the filter cylinder 207, which can discharge excess wastewater from the filter cylinder 207. A drain hole is provided at the end of the side of the drain pipe 301. A sealing cylinder 302 is fitted on the outside of the drain pipe 301. The drain hole can cooperate with the sealing cylinder 302. The opening and closing of the drain hole can be controlled by the up and down movement of the sealing cylinder 302.

[0035] Based on this, a connecting rope 305 is fixedly connected to the top of the sealing cylinder 302, and a float 306 is connected to the connecting rope 305. The connecting rope 305 and the float 306 can cooperate with each other. When the water level is higher than the preset height, the connecting rope 305 can automatically move the sealing cylinder 302 upward to open. A guide rope 307 is slidably connected to the float 306, and a magnet 308 is fixedly connected to the end of the guide rope 307. The top of the inside of the tank 1 is made of ferromagnetic material, so that the float 306 can be temporarily fixed when it moves to the top of the inside of the tank 1. At the same time, the end of the connecting rope 305 is fixedly connected to the magnet 308, thereby keeping the sealing cylinder 302 in an open state, so that the water inside the filter cylinder 207 can be continuously discharged outward.

[0036] It is worth noting that a gear ring 215 is fixedly connected to the side of the drive disc 201, and a driven gear 216 is meshed with the side of the gear ring 215. A support rod is fixedly connected to the driven gear 216. The driven gear 216 can drive the gear ring 215, causing the drive disc 201 to rotate continuously. A motor 217 is fixedly connected to the storage rack 205, and a drive gear 218 is fixedly connected to the end of the output shaft of the motor 217. The drive gear 218 has a residual gear structure. A liquid level sensor can be added inside the filter cartridge 207. When the liquid level reaches a preset height, the motor 217 can be started. The drive gear 218 is meshed with transmission gears 219 on both sides. The transmission gears 219 are respectively connected to the outside of the screw 206 and the top of the support rod. The transmission gears 219 mesh with the screw 206 and are fixedly connected to the support rod. The drive gear 218 can drive the drive disk 201 and the screw 206 in sequence by rotating one revolution at a time, so as to realize the automatic switching and automatic replacement of the adsorption block 203.

[0037] In operation, the waste gas treatment device for a coating machine according to this invention first starts the turbine fan, which then introduces the waste gas into the tank 1 through the waste gas pipe 210. The waste gas passes through the adsorption block 203, adsorbing particulate matter and some harmful gases within the waste gas. Since the aeration pipe 213 requires high gas pressure, the turbine fan enriches the waste gas after introducing it into the tank 1. When the gas pressure inside the aeration pipe 213 reaches the set pressure, the aeration pipe 213 aerates the waste gas into microbubbles and disperses them in the water. The waste gas rises from the bottom of the water to the filter cylinder 207. Simultaneously, an external water source sprays water into the filter cylinder 207 from the spray pipe 208, treating the waste gas that has risen to the filter cylinder 207. Subsequently, the waste gas, carrying a large amount of water vapor, flows along the exhaust pipe 214 to the electrocatalytic device, where it undergoes a catalytic reaction. The treated waste gas, after passing through the adsorption block 203 to adsorb excess water vapor, is discharged to the outside of the tank 1. Spray pipe 208 continuously sprays water into filter cylinder 207, causing the water level inside filter cylinder 207 to rise continuously. When magnet 308 at the top of float 306 moves close to the top of tank 1, magnet 308 on float 306 is attracted to the top of tank 1 by magnetism. The instantaneous short-distance movement of magnet 308 drives sealing cylinder 302 to move synchronously via connecting rope 305 and opens drain hole. Water inside filter cylinder 207 then continuously drops and is discharged outward along drain pipe 301. At the same time, motor 217 starts, causing drive gear 218 to rotate, which in turn drives drive disc 201 and screw 206 to rotate. Drive disc 201 then rotates adsorption block 203 to the outside of tank 1. Subsequently, screw 206 rotates and pushes adsorption block 203 downward. Adsorption block 203 at the bottom of storage rack 205 pushes adsorption block 203 on mounting rack 202 downward and separates it from mounting rack 202. At the same time, new adsorption block 203 is installed on mounting rack 202.
