[0002] Plastic spraying is a surface treatment method that sprays plastic powder on parts. The advantages are that it does not require thinners, is environmentally friendly, and is non-toxic to humans. The plastic powder is charged by high-voltage electrostatic equipment, and the coating is sprayed onto the surface of the workpiece under the action of the electric field. The powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating, and the powdery coating will be leveled and solidified after high-temperature baking. The plastic particles will melt into a dense final protective coating with different effects. Plastic spraying powder mainly includes acrylic powder, polyester powder, etc. The curing furnace of the plastic spraying industry will produce a large amount of waste gas containing volatile organic compounds, which needs to be discharged in a timely manner.

[0003] The existing waste gas treatment equipment is easily affected by impurities during the waste gas spraying process, causing the spray port to be blocked, thus affecting the operation of the equipment. Secondly, after a long period of operation, the liquid has more internal impurities, which easily increases the probability of equipment blockage during the circulation operation. Therefore, a new design was made to address this situation. Summary of the invention

[0009] Preferably, the bottom of the processing shell is fixedly connected to a processing base, and the inner side of the processing base is slidably connected to a collecting shell.

[0014] The present invention provides a waste gas treatment device in an automatic plastic spraying device. It has the following beneficial effects:

[0015] 1. The exhaust gas treatment equipment in the automatic spraying equipment is designed with a composite mechanism. The exhaust gas enters the interior of the composite shell from one side of the input mechanism, and the liquid is sprayed from one side of the spray head from the water pipe, so that the liquid and the gas are fully in contact, so that the pollutants in the exhaust gas can be dissolved and adsorbed when they come into contact with the spray liquid, thereby promoting medium transfer. After the pollutants come into contact with the filler liquid, the exhaust gas can be purified, so that the pollutants in the exhaust gas are dissolved in the liquid or absorbed and attached to the liquid surface through contact with the droplets. The gas continues to move upward and diverges to the top of the composite shell through the demister plate. It can efficiently separate the droplets in the exhaust gas to prevent the liquid from being discharged with the purified gas, thereby ensuring the stable operation of the system and meeting the emission standards. The gas contacts the filling plate during the rising process, optimizes the gas-liquid contact mode and strengthens the mass transfer process, and significantly improves the exhaust gas treatment efficiency. When the liquid is sprayed and precipitated at the bottom of the inner wall of the composite shell, the water pump is connected to the water tank to cause the liquid to spray to the side of the spray head through the water pipe, so as to achieve the effect of circulating operation. When the liquid passes through the adapter block and the spray barrel, the pressure change causes the spray barrel to rotate inside the adapter block, so as to increase the spraying range through rotation, improve the spraying effect, and improve the exhaust gas purification efficiency.

[0016] 2. The exhaust gas treatment equipment in the automatic plastic spraying equipment is designed with a spray head. The rotating bracket is made of carbon fiber material, which is light and has high corrosion resistance. When the spray liquid enters the spray shell from the spray barrel, it impacts the rotating bracket, causing the rotating bracket to rotate on the outside of the connecting block, prompting the rotating bracket to drive the columnar block to rotate and rub on the surface of the orifice plate, so as to achieve the effect of cleaning impurities and avoid clogging of the holes after long-term operation of the components, thereby affecting the normal operation of the equipment. Therefore, the components are rotated and cleaned through liquid impact, thereby extending the service life of the components.

[0017] 3. The waste gas treatment equipment in the automatic plastic spraying equipment is designed with a filtering mechanism. A water pump is used to promote the liquid inside the water tank to enter the filter housing from the water inlet pipe. The liquid enters the water diversion pipe from the water outlet pipe through the filter cover, thereby achieving the effect of liquid circulation operation. The liquid is filtered through the filter cover to filter the impurities inside the liquid to avoid a large amount of internal impurities after long-term spraying. The impurities inside the liquid are reduced by filtering, and the blockage of the liquid during the spraying process is reduced, thereby ensuring the stable operation of the system, improving the processing efficiency and extending the life of the equipment. The impurities are blocked by the filter cover and retained inside the filter housing. When cleaning is required, the electric control valve is opened to drive the impurities out with the flow of part of the liquid, so as to facilitate recycling.

[0018] 4. The waste gas treatment equipment in the automatic plastic spraying equipment is designed with a treatment mechanism. The waste gas enters the treatment shell from one side of the input mechanism. The waste gas moves upward inside the treatment shell and is guided by the baffle. Then, the larger particle impurities in the waste gas are blocked by the grille cover, so as to achieve the role of pretreatment, remove large particles of dust, paint mist and other impurities in the waste gas, and prevent these impurities from clogging subsequent treatment equipment or affecting the treatment effect. The pretreated waste gas contacts the adsorption mechanism during the rising process, so as to achieve the role of secondary treatment. Finally, the gas moves from the outlet pipe to the inside of the composite mechanism, which is convenient for subsequent treatment. With the blockage or equipment stopping, the particles are deposited at the bottom of the treatment shell, and the particles enter the collection shell, so as to achieve the role of storing waste gas particles, which is convenient for cleaning and keeps the equipment in continuous operation.

[0019] 5. The waste gas treatment equipment in the automatic spraying equipment is designed with an input mechanism. The waste gas enters the input shell from one side of the guide mechanism, and the waste gas is collected and circulated through the input shell. After the waste gas passes through the input shell, the gas pushes the elliptical bracket to rotate. The elliptical bracket can be made of engineering plastics or composite materials, which are light in weight and easy to rotate. The friction column is driven to rotate by the elliptical bracket, causing the friction column to rub the inner wall of the input shell, so as to achieve the effect of cleaning the inner wall of the equipment, reduce the adsorption of waste gas particles on the inner wall of the equipment, and reduce the agglomeration of surface impurities affecting the ventilation effect. The particles are moved again by scraping and enter the interior of the treatment shell for subsequent cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: an exhaust gas treatment device in an automatic spraying device, comprising a composite mechanism 1, a treatment mechanism 2 is connected to a pipe on one side outside the composite mechanism 1, an input mechanism 3 is fixedly connected to a side of the treatment mechanism 2 away from the composite mechanism 1, a filling plate 4 is fixedly connected to the inner wall of the composite mechanism 1, and a defogger plate 5 is fixedly connected to the upper side of the inner wall of the composite mechanism 1;

[0033] The composite mechanism 1 includes a composite shell 11, a water tank 12 is fixedly connected to one side of the outside of the composite shell 11, a water pump 13 is fixedly connected to one side of the top of the water tank 12, a water diversion pipe 14 is fixedly connected to the middle of the top of the water tank 12, a conversion block 15 is fixedly connected to the side of the outside of the water diversion pipe 14 away from the water tank 12, a spray barrel 16 is rotatably connected to the inner side of the conversion block 15, an external pipe 17 is fixedly connected to the outer side of the spray barrel 16, a spray head 18 is fixedly connected to the outer side of the external pipe 17, and a filtering mechanism 19 is fixedly connected to the outer side of the water diversion pipe 14. The exhaust gas enters the interior of the composite shell 11 from one side of the input mechanism 3, and the liquid is sprayed from the water pipe 14 from one side of the spray head 18, so that the liquid and the gas are fully in contact, so that the pollutants in the exhaust gas can be dissolved and adsorbed when they come into contact with the spray liquid, thereby promoting medium transfer. After the pollutants come into contact with the filler liquid, the exhaust gas purification can be achieved, so that the pollutants in the exhaust gas are dissolved in the liquid or absorbed and attached to the surface of the liquid through contact with the droplets. The gas continues to move upward and diverges to the top of the composite shell 11 through the demister plate 5, which efficiently separates the droplets in the exhaust gas and prevents the liquid from being purified. After that, the gas is discharged, thereby ensuring the stable operation of the system and meeting the emission standards. During the rising process, the gas contacts the filling plate 4, optimizing the gas-liquid contact mode and strengthening the mass transfer process, which significantly improves the waste gas treatment efficiency. When the liquid is sprayed and precipitated at the bottom of the inner wall of the composite shell 11, the water pump 13 is connected through the water tank 12 to prompt the liquid to spray to the side of the spray head 18 through the water pipe 14, so as to achieve the effect of circulating operation. When the liquid passes through the adapter block 15 and the spray barrel 16, the spray barrel 16 is rotated inside the adapter block 15 due to the pressure change, so as to increase the spraying range through rotation, improve the spraying effect, and improve the waste gas purification efficiency.

The rotating bracket 184 is made of carbon fiber material, which is light and has high corrosion resistance. When the spray liquid enters the inside of the spray shell 181 from the spray barrel 16, it impacts the rotating bracket 184, causing the rotating bracket 184 to rotate on the outer side of the connection block 183, prompting the rotating bracket 184 to drive the columnar block 186 to rotate and rub on the surface of the hole plate 182, so as to achieve the effect of cleaning impurities and avoid the components from clogging the holes after long-term operation, thereby affecting the normal operation of the equipment. Therefore, the components are rotated and cleaned by liquid impact, thereby extending the service life of the components.

[0035] The filter mechanism 19 includes a filter shell 191, a water inlet pipe 192 is fixedly connected to one side of the outside of the filter shell 191, a water outlet pipe 193 is fixedly connected to the top of the filter shell 191, a filter cover 194 is fixedly connected to the top of the inner wall of the filter shell 191, and an electric control valve 195 is fixedly connected to the bottom of the filter shell 191. The water pump 13 is used to cause the liquid inside the water tank 12 to enter the filter housing 191 from the water inlet pipe 192, and the liquid enters the water diversion pipe 14 from the water outlet pipe 193 through the filter cover 194, thereby achieving the effect of liquid circulation operation. The liquid is filtered through the filter cover 194, and the impurities inside the liquid are filtered to avoid a large amount of internal impurities after the spraying liquid is sprayed for a long time. The impurities inside the liquid are reduced by filtering, and the blockage of the liquid during the spraying process is reduced, thereby ensuring the stable operation of the system, improving the processing efficiency and extending the life of the equipment. The impurities are blocked by the filter cover 194 and retained in the filter housing 191. When cleaning is required, the electric control valve 195 is opened, and the impurities are driven out as part of the liquid flows, so as to facilitate recycling.

The exhaust gas enters the treatment shell 21 from one side of the input mechanism 3, and the exhaust gas moves upward inside the treatment shell 21, is guided by the baffle plate 22, and then the larger particles of impurities in the exhaust gas are blocked by the grille cover 23, so as to achieve the effect of pretreatment, remove large particles of dust, paint mist and other impurities in the exhaust gas, and prevent these impurities from clogging subsequent treatment equipment or affecting the treatment effect.

The exhaust gas contacts the adsorption plate 275, and the receiving column 274 rotates outside the columnar block 273 as the gas flushes, so that it is easy to rotate with the movement of the gas, thereby further improving the adsorption effect. The adsorption plate 275 can be made of activated carbon or fiber materials, so as to achieve the adsorption of particulate impurities and further treat the exhaust gas. Secondly, the handle 272 is pulled to remove the circular top plate 271, which is convenient for replacing the adsorption plate 275, thereby reducing the difficulty of operation and allowing the equipment to operate continuously.

[0039] The third embodiment is based on the first and second embodiments.

The exhaust gas enters the input shell 31 from one side of the guide mechanism 39, and is collected and circulated through the input shell 31. After passing through the input shell 31, the exhaust gas is pushed by the gas to rotate the elliptical bracket 35, which can be made of engineering plastics or composite materials, which are light in weight and easy to rotate. The friction column 37 is driven to rotate by the elliptical bracket 35, so that the friction column 37 rubs the inner wall of the input shell 31, thereby achieving the effect of cleaning the inner wall of the equipment, reducing the adsorption of exhaust gas particles on the inner wall of the equipment, and the agglomeration of surface impurities affecting the ventilation effect.

When the friction column 37 rubs against the inner wall of the equipment, it rotates to make the friction column 37 and the friction plate 384 frictionally fit, and the friction plate 384 rubs against the friction column 37, so as to clean the surface of the component, reduce dust on the surface of the component, avoid affecting the subsequent friction effect, and cause particles to fall off through friction, so that the particles are discharged from the inside of the beveled groove 385, making the particles easy to handle later. Secondly, when the friction plate 384 and the friction column 37 frictionally fit, friction amplitude is easily generated, so that the sliding rod 383 slides inside the cylindrical shell 381 to squeeze the first spring 382, ​​so as to achieve the effect of shock absorption and buffering, reduce the amplitude of the component, and improve the stability of equipment operation.

[0041] The guide mechanism 39 includes a funnel shell 391, a spiral plate 392 is fixedly connected to the middle of the inner side of the funnel shell 391, an external frame 393 is fixedly connected to the side of the funnel shell 391 near the spiral plate 392, a second spring 394 is fixedly connected to the inner side of the external frame 393, and a side of the external frame 393 away from the funnel shell 391 is fixedly connected to a side of the inner wall of the input shell 31. The exhaust gas is guided by the funnel shell 391 to promote centralized gas transmission, contact with the spiral plate 392, and make the gas rotate. The spiral plate 392 forces the exhaust gas to rotate along the inner wall of the pipeline to form a vortex. The solid particles, liquid droplets or mist droplets in the exhaust gas are thrown to the pipeline wall due to the centrifugal force, and are deposited or collected after separation from the gas. The funnel shell 391 is supported by the external frame 393 and the second spring 394, so as to reduce the amplitude of the components, improve the stability of equipment operation, reduce pipeline vibration, reduce component fatigue, and reduce equipment noise.

[0042] When in use, the exhaust gas enters from one side of the guide mechanism 39 inside the input mechanism 3, and is guided by the guide mechanism 39 to rotate the exhaust gas. The spiral plate 392 forces the exhaust gas to rotate along the inner wall of the pipe to form a vortex. The solid particles, liquid droplets or mist droplets in the exhaust gas are thrown to the pipe wall due to the centrifugal force, and are deposited or collected after separation from the gas. After the exhaust gas enters the input shell 31, the inner wall is scraped and cleaned by the input mechanism 3 to clean the impurities attached to the inner wall, so that the impurities flow again and enter the interior of the treatment mechanism 2. The grille cover 23 inside the treatment mechanism 2 blocks the impurities with larger particles to avoid entering the subsequent equipment and preventing the subsequent equipment from being affected, so that the particles are deposited at the bottom of the treatment shell 21, so as to facilitate the temporary storage of impurities and subsequent cleaning. The gas is guided by the baffle plate 22 to make the exhaust gas contact with the adsorption mechanism 27, and the adsorption mechanism 27 further adsorbs the particles inside the exhaust gas, thereby reducing the difficulty of subsequent treatment and facilitating replacement. The treated waste gas enters the composite mechanism 1, and the waste gas is brought into contact with the spray liquid through the composite mechanism 1, so as to purify the waste gas and make the liquid and gas fully contact, so that the pollutants in the waste gas can be dissolved and adsorbed when they come into contact with the spray liquid, thereby promoting medium transfer. After the pollutants come into contact with the filler liquid, the waste gas can be purified, so that the pollutants in the waste gas are dissolved in the liquid or absorbed and attached to the surface of the liquid through contact with the droplets, thereby achieving the waste gas treatment operation. Secondly, the spray liquid inside the composite mechanism 1 adopts a circulating operation to reduce the operating cost. When the spray liquid circulates, it is easy to cause excessive impurities in the liquid, causing blockage to the spraying operation inside the equipment. Therefore, a side of the water pipe 14 is set through the filtering mechanism 19 to promote the liquid to enter the filtering mechanism 19 and then re-circulate and spray. The impurities in the liquid are filtered by the filtering mechanism 19 to reduce the impurities from entering the circulation system and avoid impurities from blocking the spray, thereby maintaining the normal operation of the equipment.
