Description

Technical Field

[0001] This invention relates to the field of coating machine exhaust gas treatment technology, specifically a dual-tower treatment structure for coating machine exhaust gas. Background Technology

[0002] When a coating machine is in use, the generated exhaust gas needs to be collected and treated to prevent the exhaust gas from affecting the air. In the process of treating the exhaust gas, the filter structure and neutralization with the solvent are used to form pollution-free gas, which effectively improves the safety of the coating machine during use and the safety of exhaust gas discharge. However, the existing coating machine exhaust gas treatment devices still have some problems in use.

[0003] In the prior art, the patent publication (announcement) number CN215233036U, entitled "A Waste Gas Treatment Device for a Coating Machine," includes a body, a water tank, a treatment chamber, an exhaust fan, and a treatment mechanism. The water tank is fixedly installed on the top of the body, and the treatment chamber is fixedly installed inside the body. An exhaust fan is fixedly installed on the inner wall of the treatment chamber. Waste gas is introduced into the device through an air inlet pipe. The water tank then performs dust suppression on the introduced waste gas. Heating elements heat and evaporate the dust-suppressed wastewater. The exhaust fan then conducts the evaporated waste gas through an air inlet pipe to the treatment mechanism for purification and filtration. The waste gas undergoes multi-layer purification and filtration through layers of filter elements. The treated waste gas is then treated with ozone by an ozone generator and discharged through an exhaust pipe, effectively improving the waste gas treatment effect and enhancing the device's practicality. However, in actual use, relying solely on filter elements can easily lead to incomplete waste gas purification, and frequent filter element replacements result in material waste.

[0004] In addition, in the prior art, the authorized publication (announcement) number: CN216878345U, "a waste gas treatment device for a coating machine", includes a drying box, a purification barrel fixedly connected to one end of the exhaust pipe, a guide pipe fixedly connected to the top of the purification barrel, a filter pipe provided on the guide pipe, a fixing strip and a sealing groove respectively provided on the outer side of the filter pipe, a groove is opened on the rear surface of the fixing strip, a slot is symmetrically opened on the inner side of the groove, a sealing cover is hinged to the inner side of the sealing groove, a U-shaped elastic element that engages with the groove is fixedly installed on the outer side of the sealing cover, and a locking block that engages with the slot is fixedly installed on both sides of the U-shaped elastic element;

[0005] During the operation of the above-mentioned device, when it is necessary to open the sealing cover, first squeeze the opening of the U-shaped elastic element to make it elastically deform, so that the locking block connected to it disengages from the slot opened by the fixing strip, and then the sealing cover is opened from the inside of the sealing slot. When it is necessary to remove the dust screen, first move the L-shaped stop bar to make the torsion spring elastically deform, so that one end of the L-shaped stop bar disengages from the restriction of the connecting block position, and then the connecting block is taken out from the inside of the connecting slot, and the dust screen is taken out from the inside of the exhaust hood. However, during use, the filtration and purification methods used are prone to clogging after long-term operation, which affects the purification effect and requires frequent replacement. When replacing, the coating machine is inconvenient to work normally, which affects the work efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a dual-tower treatment structure for exhaust gas from a coating machine, in order to solve the problems mentioned in the background art, such as the incomplete purification of exhaust gas caused by using only filter cartridges, the waste of materials due to the need for frequent filter cartridge replacement, the clogging of the filtration and purification methods after long-term operation, the impact on the purification effect, the inconvenience of frequent replacement of the filter cartridges, and the resulting inefficiency of the coating machine.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dual-tower treatment structure for coating machine exhaust gas, wherein an absorption tower is provided to facilitate the conveying of coating machine exhaust gas at the end of the pipe;

[0008] Includes: an air inlet component 1, installed on the lower side of the inner surface of the absorption tower 1, and a conveying component installed on the outer surface of the air inlet component 1, and an aluminum profile bracket installed on the lower surface of the conveying component; a level gauge is connected to the lower side of the outer surface of the absorption tower 1, and an observation port is installed on the side of the outer surface of the absorption tower 1.

[0009] A support is installed on the lower middle side of the first absorption tower, and a spray pipe is installed on the lower surface of the support. A spray head is installed on the lower surface of the spray pipe, and a liquid replenishment pipe is provided on the upper surface of the spray pipe. Thus, a tray is connected through the outer surface of the liquid replenishment pipe.

[0010] A support frame is installed on the lower middle side of the first absorption tower and on the upper surface of the first spray pipe. A tray is installed on the upper surface of the support frame. A nesting groove is opened on the outer surface of the tray, and a nesting member is nested on the inner surface of the nesting groove.

[0011] The second replenishment pipe is connected to the lower inner surface of the first absorption tower. The second spray pipe is installed on the upper surface of the second replenishment pipe. The second tray is provided on the upper outer surface of the second spray pipe. The first tray is provided on the lower outer surface of the second spray pipe. The third spray pipe is provided on the upper surface of the second tray. A gas delivery pipe is installed on the upper outer surface of the first absorption tower.

[0012] A tap water storage tank is connected to the right side of the outer surface of the absorption tower one, and the inner surface of the tap water storage tank is divided into water tank one, water tank two, water tank three and water tank four, and level gauges are installed on the front and rear sides of the outer surface of the tap water storage tank respectively.

[0013] Absorption tower two is installed on the right side of the outer surface of the gas conveying pipe, and an air inlet two is installed on the lower side of the inner surface of absorption tower two. The inner surface of absorption tower two is assembled from bottom to top with tray three, tray four and demister support, and demister packing is installed on the upper surface of the demister support. Furthermore, an exhaust port is opened on the upper surface of absorption tower two.

[0014] Preferably, the absorption tower and the air inlet form an integrated structure, and the upper surface of the air inlet is arc-shaped. The absorption tower, the level gauge, and the observation port form an integrated structure, while the conveying component and the aluminum profile bracket form a supporting structure.

[0015] The above structure effectively discharges exhaust gas during use, facilitating the formation of a stable mixed spray liquid with the arc-shaped air intake structure for initial purification.

[0016] Preferably, the support member is embedded in the lower inner surface of the absorption tower, and the support member and the spray pipe form a limiting nested structure, and the spray pipe and the spray head form an integrated structure, with the spray pipe set at an angle to the central axis of the inner surface of the absorption tower.

[0017] The above structure facilitates stable support and positioning during use, preventing detachment.

[0018] Preferably, the replenishment pipe and the tray form a through structure, and the tray, support frame and absorption tower form an integrated structure. The tray and the nesting member form a limiting nesting structure through the nesting groove and the nesting member, and the nesting member is evenly arranged on the outer surface of the tray.

[0019] The above structure allows for effective and stable support during use, and works in conjunction with the replenishment pipe to control the liquid storage level on the upper side of the tray.

[0020] Preferably, the upper surface of the nesting component has a slot, and a locking component is installed on the inner surface of the slot. A bolt is connected through the inner surface of the locking component, and a cylindrical tension spring is nested on the outer surface of the bolt. An overflow cover is attached to the upper surface of the cylindrical tension spring, and the overflow cover is nested on the outer surface of the nesting component. An overflow groove is provided on the outer surface of the overflow cover.

[0021] The above structure facilitates stable assembly during use and prevents detachment.

[0022] Preferably, the engaging member forms a limiting engaging structure with the nesting member through the engaging groove, and the engaging member and the bolt form a through structure. The engaging member and the overflow cover are elastically threaded together through the bolt and the cylindrical tension spring. Meanwhile, the overflow grooves are evenly distributed on the lower side of the outer surface of the overflow cover, and the lower end of the overflow cover is higher than the upper end of the tray.

[0023] The above structure allows for effective nested assembly during use, thereby controlling the stability of the rising gas and enabling gas to pass through the overflow channel to form a water seal. It also facilitates the pressure boosting of the rising gas at the bottom.

[0024] Preferably, the second replenishment pipe and the second spray pipe form a through structure with the first absorption tower, and the second spray pipe and the second replenishment pipe are located on the upper and lower sides of the first tray. The second tray is embedded in the upper side of the inner surface of the first absorption tower, and the third spray pipe is located on the upper surface of the second tray.

[0025] With the above structure, the lower inner surface of the absorption tower one can be automatically replenished with liquid during use. In conjunction with the use of spray pipe two and spray pipe three, the mixed gas can be gradually sprayed onto the upper surface of tray one and tray two.

[0026] Preferably, the tap water storage tank is assembled with spray pipe one, replenishment pipe one, replenishment pipe two, spray pipe two and spray pipe three respectively, and the tap water storage tank is divided into water tank one, water tank two, water tank three and water tank four.

[0027] The above structure allows for effective assembly during use. Combined with the grouped internal storage structure, it forms independent delivery positions, preventing mixing and ensuring different concentrations of liquid in different locations. Furthermore, the internal liquid concentration is gradually reduced by the use of water tanks one, two, three, and four.

[0028] Preferably, the second absorption tower is integrated with the first absorption tower via a gas delivery pipe, and the third and fourth trays and the demister support are embedded in the inner surface of the second absorption tower from bottom to top, and the demister support and the demister packing form a nested structure.

[0029] The above structure allows for effective interconnection and assembly during use, and gradually purifies the demister mesh filler within the demister mesh support, effectively controlling the purification intensity of the device and preventing exhaust from affecting the air.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. The coating machine exhaust gas dual-tower treatment structure is equipped with absorption tower one and absorption tower two for convenient dual-tower purification. By assembling the inclined air inlet components one and two, the use of the spray head installed with spray pipe one is improved, effectively mixing and purifying the exhaust gas with atomized liquid. In conjunction with the collection at the bottom of absorption tower one and recycling, the liquid can be replaced when it becomes unusable under monitoring conditions. The liquid level gauge is used to replenish the liquid when the liquid remaining at the bottom decreases, in conjunction with the replenishment pipe two.

[0032] 2. The coating machine's dual-tower exhaust gas treatment structure is equipped with positioning and assembly support components, a stable assembly of the spray pipe, and a support frame connected to its upper side, which in turn assembles the tray. The position of the locking components is controlled by the nesting components connected to its upper side. An overflow cover is connected through the use of a cylindrical tension spring, and the assembled overflow trough can effectively form a liquid layer at the upper end of the tray, and direct excess liquid to the lower side of the absorption tower and upward from the bottom of the tray, thereby improving the ventilation and purification stability of the device through the overflow trough. The purified liquid is replenished to the upper side through the replenishment pipe.

[0033] 3. The coating machine's dual-tower exhaust gas treatment structure is equipped with a gas delivery pipe for easy connection, effectively transporting the liquid after two purifications to absorption tower two, as well as tower trays three and four assembled in conjunction with absorption tower two for further purification. The purified liquid is discharged through the exhaust port via the demister mesh packing on the demister mesh support. The tap water storage tanks used in the machine are respectively assembled into water tank one, water tank two, water tank three, and water tank four, which correspond to different purification positions, forming a liquid replenishment and transportation system. The liquid level is measured by level gauges, thereby automatically increasing the supply. Attached Figure Description

[0047] The support frame 11 is installed on the middle and lower side of the absorption tower 1 and is located on the upper surface of the spray pipe 8. The upper surface of the support frame 11 is equipped with a tray 12, and the outer surface of the tray 12 is provided with a nesting groove 13. The inner surface of the nesting groove 13 is nested and connected with a nesting piece 14.

[0048] A second liquid supply pipe 15 is connected to the lower inner surface of the first absorption tower 1. A second spray pipe 16 is installed on the upper surface of the second liquid supply pipe 15. A second tray 17 is provided on the upper outer surface of the second spray pipe 16. A first tray 12 is provided on the lower outer surface of the second spray pipe 16. A third spray pipe 18 is provided on the upper surface of the second tray 17. A gas delivery pipe 19 is installed on the upper outer surface of the first absorption tower 1.

[0049] The absorption tower 1 and the air inlet 2 form an integrated structure, and the upper surface of the air inlet 2 is arc-shaped. The absorption tower 1, the level gauge 5, and the observation port 6 form an integrated structure, while the conveying component 3 and the aluminum profile bracket 4 form a supporting structure.

[0050] The support member 7 is embedded in the lower part of the inner surface of the absorption tower 1, and the support member 7 and the spray pipe 8 form a limiting nested structure. The spray pipe 8 and the spray head 9 form an integrated structure. The spray pipe 8 is set at an angle to the central axis of the inner surface of the absorption tower 1.

[0051] The replenishment pipe 10 and the tray 12 form a through structure, and the tray 12, support frame 11 and absorption tower 1 form an integrated structure. The tray 12 and the nesting member 14 form a limiting nesting structure through the nesting groove 13. At the same time, the nesting member 14 is evenly arranged on the outer surface of the tray 12.

[0052] The upper surface of the nesting member 14 is provided with a slot 1401, and a locking member 1402 is engaged with the inner surface of the slot 1401. A bolt 1403 is connected through the inner surface of the locking member 1402. Meanwhile, a cylindrical tension spring 1404 is nested and connected to the outer surface of the bolt 1403. Furthermore, an overflow cover 1405 is attached to the upper surface of the cylindrical tension spring 1404 and nested on the outer surface of the nesting member 14. An overflow groove 1406 is provided on the outer surface of the overflow cover 1405.

[0053] The engaging component 1402 forms a limiting engaging structure with the nesting component 14 through the slot 1401, and the engaging component 1402 forms a through structure with the bolt 1403. The engaging component 1402 forms an elastic threaded assembly with the overflow cover 1405 through the bolt 1403 and the cylindrical tension spring 1404. Meanwhile, the overflow groove 1406 is evenly distributed on the lower side of the outer surface of the overflow cover 1405, and the lower end of the overflow cover 1405 is higher than the upper end of the tray 12.

[0054] The replenishment pipe 215 and the spray pipe 216 form a through structure with the absorption tower 11. The spray pipe 216 and the replenishment pipe 215 are located on the upper and lower sides of the tray 12. The tray 217 is embedded in the upper side of the inner surface of the absorption tower 11. Meanwhile, the spray pipe 318 is located on the upper surface of the tray 217.

[0055] In use, the waste gas generated by the coating machine is conveyed to the lower inner surface of the absorption tower 1 by the conveying component 3 installed on the aluminum profile bracket 4 and the air inlet component 2 installed. The gas is dispersed at the bottom of the absorption tower 1 by the arc-shaped structure of the outer surface of the air inlet component 2. The amount of purified liquid retained is controlled by the liquid level gauge 5. After purification by the circulation structure, the purified liquid is retained at the bottom of the absorption tower 1 again. When the amount of purified liquid retained is insufficient, the liquid is replenished by the liquid replenishment pipe 15. When the gas is evenly dispersed, the spray head 9 assembled by the spray pipe 8 installed on the support component 7 effectively mixes the atomized liquid with the gas for purification.

[0056] After purification, the gas flows through the nested groove 13 of the tray 12 assembled on the support frame 11, and the nested member 14 embedded in the nested groove 13, to the space between tray 12 and tray 2 17. In conjunction with the replenishment pipe 10 penetrating tray 12, it automatically replenishes the liquid when the liquid remaining on the upper side of tray 12 decreases. It also works with the locking member 1402 assembled with the slot 1401 provided in the nested member 14, and the overflow cover 1 assembled with the bolt 1403 connected to the locking member 1402 passing through the cylindrical tension spring 1404. 405, effectively cooperating with the nesting part 14 to form a water seal, can effectively bring the rising gas and liquid into contact, and with the overflow trough 1406 set in the overflow cover 1405, the excess liquid can also be left at the bottom of the absorption tower 1 to retain purified liquid for use. After the rising gas comes into contact with the liquid, it is used in conjunction with the use of the spray pipe 2 16 for purification. Thus, the spray pipe 3 18 on the tray 2 17 is used for purification in the same way, and with the help of the gas conveying pipe 19, the passing gas is transported to the absorption tower 2 26.

[0057] Water storage tank 20 is connected to the right side of the outer surface of absorption tower 1. The inner surface of water storage tank 20 is divided into water tank 1 21, water tank 22, water tank 3 23 and water tank 4 24. Liquid level gauges 5 are installed on the front and rear sides of the outer surface of water storage tank 20.

[0058] Absorption tower 26 is installed on the right side of the outer surface of the gas delivery pipe 19. An air inlet 25 is installed on the lower side of the inner surface of absorption tower 26. The inner surface of absorption tower 26 is assembled from bottom to top with tray 3 27, tray 4 28 and demister support 29. At the same time, demister packing 30 is installed on the upper surface of demister support 29. An exhaust port 31 is opened on the upper surface of absorption tower 26.

[0059] The tap water storage tank 20 is assembled with the spray pipe 1 8, the replenishment pipe 1 10, the replenishment pipe 2 15, the spray pipe 2 16 and the spray pipe 3 18 respectively, and the tap water storage tank 20 is divided into water tank 1 21, water tank 2 22, water tank 3 23 and water tank 4 24.

[0060] Absorption tower 26 is integrated with absorption tower 1 through gas delivery pipe 19. Tray 3 27, tray 4 28 and demister support 29 are embedded in the inner surface of absorption tower 26 from bottom to top, and demister support 29 and demister packing 30 form a nested structure.

[0061] When the gas passes through the gas delivery pipe 19 after secondary purification, the tap water storage tank 20 connected to the lower outer surface of the assembled absorption tower 1, together with the internally separated water tanks 21, 22, 23, and 24, provides water replenishment or water recycling to the purification location. The installation of the gas inlet 25 on the gas delivery pipe 19 and the absorption tower 26, as well as the trays 27 and 28 on the absorption tower 26, effectively purify the gas step by step as in the absorption tower 1. In conjunction with the demister mesh packing 30 assembled on the demister mesh support 29, the mixture of gas and liquid is prevented from generating bubbles, thus effectively discharging the purified gas through the exhaust port 31.

[0062] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
