Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and specifically relates to a waste gas treatment device for paint production. Background Technology

[0002] Paint is a viscous liquid applied to the surface of an object to be protected or decorated, forming a firmly adhering continuous film. It is typically based on resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, formulated with organic solvents or water. The paint production process generates a large amount of harmful gases, and direct emission of these gases would cause significant environmental damage. Therefore, waste gas treatment equipment is necessary to treat these harmful gases during paint production.

[0003] The existing method generally uses activated carbon adsorption boxes to treat the waste gas generated during paint production. The activated carbon is used to remove harmful substances from the waste gas. However, after the activated carbon in the existing drawer-type activated carbon adsorption box becomes saturated, the machine needs to be shut down to replace the activated carbon before it can be restarted. The process of replacing the activated carbon wastes a lot of time and seriously affects the efficiency of waste gas treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a waste gas treatment device for paint production that is simple in structure and reasonably designed in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A waste gas treatment device for paint production includes a gas collection assembly. A partition is fixedly connected inside the gas collection assembly. A diversion plate is fixedly installed on the inner side wall of the gas inlet end of the gas collection assembly. Two diversion holes are opened on the diversion plate. A sealing plate is provided on the side of the diversion plate away from the gas inlet end of the gas collection assembly. Each sealing plate has a support frame fixedly connected to both ends, extending into the gas collection assembly. One end of the support frame inside the gas collection assembly is inserted into the partition plate. A set of drive shafts is rotatably connected between the two support frames. A sealing belt ring is drivenly connected to the drive shaft. A through hole is opened on the sealing belt ring on both sides of the drive shaft, which is aligned with the diversion hole. A filter screen is fixedly connected in the through hole. An adjustment mechanism is installed inside the gas collection assembly. A treatment component is installed on both sides of the gas collection assembly. A vibration mechanism is installed below the treatment component. An anti-misoperation mechanism is also installed inside the gas collection assembly.

[0007] As a further optimization of the present invention, the gas collection assembly includes a box, a partition fixedly connected inside the box, and gas collection hoods connected to both ends of the box. An air inlet pipe connector is fixedly inserted through one of the gas collection hoods, and an exhaust pipe connector is fixedly inserted through the other gas collection hood.

[0008] As a further optimization of the present invention, mounting holes are provided on the side walls of the box on both sides of the partition. The free end of the support frame extends through the mounting holes into the box body. The sealing belt ring is attached to the side of the diverter plate near the diverter plate.

[0009] As a further optimization of the present invention, the adjustment mechanism includes a lower gear fixedly installed at the bottom end of one of the transmission shafts, a servo motor fixedly installed on the bottom wall of the housing inside the lower gear, a drive gear fixedly connected to the output end of the servo motor, and when the sealing plate is in contact with the outer wall of the housing, the lower gear and the drive gear mesh with each other.

[0010] As a further optimization of the present invention, a dust cover is fixedly connected to the inner wall of the sealing plate, and a receiving groove is opened on the side of the dust cover near the sealing belt ring. A scraper is fixedly installed in the receiving groove, and a collection box is fixedly connected to the bottom of the dust cover.

[0011] As a further optimization of the present invention, sliding holes are provided on both sides of the outer wall of the box, and a set of support rails are provided below each sliding hole. The two ends of the support rails are fixedly connected to the inner wall of the box and the partition, respectively. The processing component includes a drawer slidably connected above the support rails. A handle is fixedly connected to one end of the drawer outside the box, and a breathable mesh plate is rotatably connected to the bottom of the other end of the drawer through a hinge. A first guide plate is fixedly connected to the support rail near the air inlet end of the box, and a second guide plate is fixedly connected to the support rail near the exhaust end of the box.

[0012] As a further optimization of the present invention, the vibration mechanism includes a rotating shaft arranged between each set of support rails, with support rollers integrally formed at both ends of the rotating shaft, and multiple annularly distributed protrusions fixedly installed on the periphery of each of the two support rollers, and multiple metal springs fixedly connected to the rotating shaft.

[0013] As a further optimization of the present invention, the anti-misoperation mechanism includes a magnetic plate fixedly connected to one end of the drawer inside the box, an electromagnet fixedly installed on the partition plate and aligned with the magnetic plate, and a connecting seat fixedly installed on the top wall of the inner cavity of the box via an ear plate, with a positive terminal and a negative terminal electrically connected to the electromagnet installed on the connecting seat.

[0014] As a further optimization of the present invention, an upper gear is fixedly connected to the top of the transmission shaft near the sealing plate, a reduction gearbox is fixedly installed on the top wall of the housing above the upper gear, a reduction gear set is installed inside the reduction gearbox, a linkage gear that meshes with the upper gear is fixedly connected to the input end of the reduction gearbox, and a conductive plate that is electrically connected to an external power source is fixedly connected to the output end of the reduction gearbox through an insulating shaft.

[0015] The beneficial effects of this invention are as follows:

[0016] The chamber is divided into two independent treatment compartments by a partition. The diversion plate has diversion holes that connect to the two treatment compartments respectively. Each diversion hole has a sealing belt ring with a filter screen installed in the middle section. When the activated carbon particles in the treatment compartment are saturated and need to be replaced, the user can first drive the sealing belt ring to rotate via the servo motor to close one of the diversion holes and replace the activated carbon particles in that treatment compartment. Then, the user can open the previously closed diversion hole and close the other diversion hole to replace the activated carbon particles in the second treatment compartment. This allows for the replacement of the activated carbon particles filling the drawer without stopping the machine, greatly improving the efficiency of waste gas treatment.

[0017] When the filter screen rotates to the drive shaft position along with the sealing belt ring, the dust clogging the filter screen holes will be squeezed to the outside of the filter screen due to the compression of the drive shaft and the bending action of the filter screen itself. At this time, the scraper can scrape off the dust attached to the filter screen as the filter screen rotates. The scraped dust falls into the collection box for storage under its own gravity, eliminating the need for users to frequently disassemble the filter screen for cleaning, making it convenient for users.

[0018] Through the coordinated arrangement of components such as magnetic plates, electromagnets, positive terminals, negative terminals, and conductive plates, when the sealing belt rotates and the two filter screens align with the diversion holes, the two ends of the conductive plates respectively come into contact with the positive and negative terminals, energizing the electromagnet and firmly attracting the drawer. When the sealing belt rotates and the two filter screens are misaligned with the diversion holes, the conductive plates rotate 90 degrees, de-energizing the electromagnet. At this point, the drawer can be opened to replace the activated carbon granules, preventing accidental opening of the drawer by the user without closing the corresponding diversion holes, which could lead to the leakage of untreated exhaust gas.

[0019] When the user pushes the drawer into the cabinet, the protrusions on the side of the support roller can drive the rotating shaft to rotate. Multiple metal springs are fixedly connected to the rotating shaft. When the rotating shaft rotates, the metal springs rotate synchronously and strike the breathable mesh plate. When the drawer filled with activated carbon particles is pushed into the cabinet, the metal springs can strike the breathable mesh plate to generate vibration, which compacts the activated carbon particles in the drawer and improves the adsorption effect of the activated carbon particles.

Detailed Implementation

[0033] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] like Figures 1-3 As shown, a waste gas treatment device for paint production includes a box 101 for treating waste gas. A support leg 102 is installed at the bottom of the box 101. The support leg 102 is used to support the box 101 to a suitable height to isolate the ground moisture from corroding the box 101 and extend the service life of the box 101.

[0035] Both ends of the housing 101 are connected to a gas collection hood 104. One gas collection hood 104 is fixedly equipped with an air inlet pipe connector 105, and the other gas collection hood 104 is fixedly equipped with an exhaust pipe connector 106. When treating exhaust gas, the exhaust pipe of the exhaust gas can be connected to the air inlet pipe connector 105, so that the exhaust gas enters the housing 101 through the air inlet pipe connector 105 for treatment. The treated exhaust gas is then discharged through the exhaust pipe connector 106 and its connected pipe.

[0036] like Figures 2-3 As shown, a partition 103 is fixedly connected inside the housing 101. The partition 103 is made of magnetic shielding material. The partition 103 is used to divide the housing 101 into two independent processing compartments. A diverter plate 201 is fixedly installed on the inner side wall of the air inlet end of the housing 101. Two diverter holes 202 are opened on the diverter plate 201, and the two diverter holes 202 are respectively connected to the two processing compartments.

[0037] like Figures 3-5As shown, a mounting hole 203 is provided on the side wall of the housing 101 away from the intake pipe connector 105 of the splitter plate 201. A sealing plate 204 is provided outside the mounting hole 203. Each sealing plate 204 has a support frame 205 fixedly connected to both ends. The support frame 205 extends through the mounting hole 203 through the side wall of the housing 101 into the processing compartment. The end of the support frame 205 located in the processing compartment is inserted into the partition plate 103. A set of drive shafts 206 is rotatably connected between the two support frames 205. A sealing belt ring 207 is drivenly connected to the drive shaft 206. One side of the sealing belt ring 207 is in contact with the splitter plate 201 to control the splitter plate 201. The flow divider hole 202 on the drive shaft 206 is sealed. The sealing belt rings 207 on both sides of the drive shaft 206 are provided with through holes. Filter screens 208 are fixedly connected in the through holes. When the sealing belt rings 207 rotate and the two filter screens 208 rotate to coincide with the flow divider hole 202, the exhaust gas can pass through the filter screens 208 and enter the corresponding treatment chamber. The filter screens 208 are used to perform preliminary filtration of the exhaust gas and remove large particulate impurities in the exhaust gas. When the sealing belt rings 207 rotate and the two filter screens 208 rotate to be misaligned with the flow divider hole 202, the flow divider hole 202 is blocked by the sealing belt rings 207, thus sealing the flow divider hole 202.

[0038] like Figure 5 and Figure 7 As shown, a lower gear 301 is fixedly installed at the bottom of one of the drive shafts 206. A servo motor 302 is fixedly installed on the bottom wall of the housing 101 inside the lower gear 301. The output end of the servo motor 302 is fixedly connected to a drive gear 303. The drive gear 303 is set inside the lower gear 301 to facilitate the removal of the support frame 205 through the mounting hole 203 and disassembly of the support frame 205. When the side of the sealing plate 204 connected to the support frame 205 slides to fit against the outer wall of the housing 101, the lower gear 301 and the drive gear 303 mesh with each other. At this time, the servo motor 302 can drive the lower gear 301 to rotate through the drive gear 303, thereby driving the sealing belt ring 207 connected to the drive shaft 206 to rotate and adjusting the position of the filter screen 208.

[0039] like Figure 5 and Figure 8As shown, a dust cover 304 is fixedly connected to the inner wall of the sealing plate 204. A receiving groove is provided on the side of the dust cover 304 near the sealing belt ring 207. The dust cover 304 is sleeved on one end of the sealing belt ring 207 through the receiving groove. A scraper 306 is fixedly installed in the receiving groove. A collection box 305 is fixedly connected to the bottom of the dust cover 304. When the filter screen 208 rotates with the sealing belt ring 207 to the position of the drive shaft 206, the dust clogging the mesh of the filter screen 208 will be squeezed to the outside of the filter screen 208 by the squeezing of the drive shaft 206 and the bending action of the filter screen 208 itself. At this time, the scraper 306 can scrape off the dust attached to the filter screen 208 when the filter screen 208 rotates. The scraped dust falls into the collection box 305 installed at the bottom of the dust cover 304 under its own gravity for storage. Users do not need to frequently disassemble the filter screen 208 for cleaning, which is convenient for users.

[0040] like Figures 1-3 As shown, sliding holes 401 are provided on both outer walls of the box 101. The sliding holes 401 are connected to the treatment chambers on both sides of the partition 103. A set of support rails 402 is provided below each sliding hole 401. The two ends of the support rails 402 are fixedly connected to the inner wall of the box 101 and the partition 103, respectively. A drawer 403 for filling activated carbon particles is slidably connected above the support rails 402. The activated carbon particles filled in the drawer 403 adsorb harmful substances in the exhaust gas, thereby achieving the purpose of treating harmful substances.

[0041] like Figures 7-9 As shown, a handle 404 is fixedly connected to one end of drawer 403 outside the box 101, which makes it convenient to pull drawer 403 out of the box 101 when replacing activated carbon granules. A ventilated mesh plate 405 is rotatably connected to the bottom of the other end of drawer 403 via hinge 406. Ventilation holes are provided on the ventilated mesh plate 405 so that gas can flow through the ventilation holes and enter the drawer 403.

[0042] like Figure 2 As shown, a first guide plate 407 is fixedly connected to the support rail 402 near the air inlet end of the housing 101, and a second guide plate 408 is fixedly connected to the support rail 402 near the exhaust end of the housing 101. The first guide plate 407 and the second guide plate 408 are set to guide the exhaust gas, so that after the exhaust gas enters the housing 101, it first enters the treatment chamber between the upper and lower drawers 403. At this time, the exhaust gas is blocked by the second guide plate 408 and cannot be directly discharged through the exhaust end of the housing 101. It needs to enter the drawer 403 and be adsorbed by the activated carbon particles filled in the drawer 403, and then be discharged through the exhaust pipe joint 106.

[0043] like Figures 2-3 , Figure 9 and Figure 11 As shown, a rotating shaft 501 is provided between a set of support rails 402 at the bottom of each drawer 403. Both ends of the rotating shaft 501 are integrally formed with support rollers 502. The ends of the support rollers 502 are rotatably connected to the side walls of the support rails 402. Multiple annularly distributed protrusions 503 are fixedly installed on the periphery of the two support rollers 502. The protrusions 503 are aligned with the ventilation holes opened on the ventilation mesh plate 405. When the user slides the drawer 403 and drives the ventilation mesh plate 405 to slide, it can drive the support rollers 502 and the rotating shaft 501 to rotate. Multiple metal springs 504 are fixedly connected to the rotating shaft 501. When the rotating shaft 501 rotates, the metal springs 504 rotate synchronously and tap the ventilation mesh plate 405. When the drawer 403 filled with activated carbon particles is pushed into the box 101, the metal springs 504 can tap the ventilation mesh plate 405 to generate vibration, which compacts the activated carbon particles filled in the drawer 403 and improves the adsorption effect of the activated carbon particles.

[0044] like Figure 3 , Figure 6 , Figure 10 and Figure 12As shown, a magnetic plate 601 is fixedly connected to one end of drawer 403 inside the housing 101. An electromagnet 602, aligned with the magnetic plate 601, is fixedly installed on the partition 103. A connecting seat 604 is fixedly installed on the top wall of the inner cavity of the housing 101 via an ear plate 603. A positive terminal 605 and a negative terminal 606, electrically connected to the electromagnet 602, are installed on the connecting seat 604. An upper gear 701 is fixedly connected to the top of the drive shaft 206 near the sealing plate 204. A reduction gearbox 702 is fixedly installed on the top wall of the housing 101 above gear 701. A reduction gear set is installed inside the reduction gearbox 702. A linkage gear 703 that meshes with the upper gear 701 is fixedly connected to the input end of the reduction gearbox 702. A conductive plate 705 electrically connected to an external power source is fixedly connected to the output end of the reduction gearbox 702 via an insulating shaft 704. A sealing cover 706 made of insulating material is fixedly installed on the insulating shaft 704. The opening end of the sealing cover 706... The conductive sheet 705 slides in contact with the connecting seat 604 for dust prevention. When the servo motor 302 drives the sealing belt ring 207 to rotate, causing the two filter screens 208 to rotate until they coincide with the diversion hole 202, the two ends of the conductive sheet 705 are respectively attached to the positive terminal 605 and the negative terminal 606, supplying power to the electromagnet 602. At this time, the magnetism of the electromagnet 602 and the adjacent end of the magnetic plate 601 are opposite, and the magnetic force tightly attracts the drawer 403, making it impossible to open the drawer 403. When the servo motor 302 drives the sealing belt ring 207 to rotate in the opposite direction, causing the two filter screens 208 to rotate until they are misaligned with the diversion hole 202, the upper gear 701, in conjunction with the linkage gear 703 and the reduction gearbox 702, drives the conductive sheet 705 to rotate 90 degrees. At this time, the electromagnet 602 is de-energized, and the drawer 403 can be opened to replace the activated carbon granules. This avoids the problem of untreated exhaust gas leakage caused by the user accidentally opening the drawer 403 without closing the corresponding diversion hole 202.

[0045] It should be noted that, in the use of this waste gas treatment equipment for paint production, activated carbon granules are first filled into drawer 403, and then drawer 403 is pushed into housing 101. Since support rollers 502 and rotating shafts 501 are installed on the support rails 402 below drawer 403, and the support rollers 502 are provided with protrusions 503 on their periphery that are aligned with the ventilation holes opened in the ventilation mesh plate 405, when the user pushes drawer 403 into housing 101, the protrusions 503 can drive the rotating shaft 501 to rotate. Multiple metal springs 504 are fixedly connected to the rotating shaft 501. When the rotating shaft 501 rotates, the metal springs 504 rotate synchronously and strike the ventilation mesh plate 405. When drawer 403 filled with activated carbon granules is pushed into housing 101, the metal springs 504 strike the ventilation mesh plate 405 to generate vibration, which compacts the activated carbon granules filled in drawer 403 and improves the adsorption effect of activated carbon granules.

[0046] After pushing drawer 403 into housing 101, the user first drives drive shaft 206 to rotate via servo motor 302, adjusting the position of sealing belt ring 207 so that the two filter screens 208 installed on sealing belt ring 207 rotate to align with the corresponding diversion holes 202. Then, the user connects exhaust pipe to intake pipe connector 105. After preliminary filtration by filter screen 208, exhaust gas enters treatment chamber and is treated by activated carbon granules filled in drawer 403. When the activated carbon granules in treatment chamber are saturated and need to be replaced, the user can first... The servo motor 302 drives the sealing belt ring 207 to rotate, closing one of the diversion holes 202 and replacing the activated carbon particles in the drawer 403 of the treatment chamber connected to the diversion hole 202. After replacement, the closed diversion hole 202 is opened, and the servo motor 302 drives the sealing belt ring 207 to close the other diversion hole 202, thereby replacing the activated carbon particles in the drawer 403 of the other treatment chamber. This allows for the replacement of the activated carbon particles filling the drawer 403 without stopping the machine, greatly improving the efficiency of waste gas treatment.

[0047] When the filter screen 208 rotates with the sealing belt ring 207 to the position of the drive shaft 206, the dust clogging the mesh of the filter screen 208 will be squeezed to the outside of the filter screen 208 by the squeezing of the drive shaft 206 and the bending of the filter screen 208 itself. At this time, the scraper 306 can scrape off the dust attached to the filter screen 208 when the filter screen 208 rotates. The scraped dust falls into the collection box 305 for storage under its own gravity, eliminating the need for users to frequently disassemble the filter screen 208 for cleaning, making it convenient for users.

[0048] Since a magnetic plate 601 is installed on drawer 403 and an electromagnet 602 is installed on partition 103, when the sealing belt ring 207 rotates and causes the two filter screens 208 to rotate until they coincide with the diversion hole 202, the two ends of the conductive sheet 705 are respectively attached to the positive terminal 605 and the negative terminal 606, supplying power to the electromagnet 602. At this time, the magnetism of the electromagnet 602 and the adjacent ends of the magnetic plate 601 are opposite, and the magnetic field force tightly attracts the drawer 403, making it impossible to open the drawer 403. When the sealing belt ring 207 rotates and causes the two filter screens 208 to rotate until they are misaligned with the diversion hole 202, the upper gear 701, in conjunction with the linkage gear 703 and the reduction gear set installed in the reduction gearbox 702, drives the conductive sheet 705 to rotate 90 degrees. At this time, the electromagnet 602 is de-energized, and the drawer 403 can be opened to replace the activated carbon granules. This avoids the problem of untreated exhaust gas leakage caused by the user accidentally opening the drawer 403 without closing the corresponding diversion hole 202.

[0049] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
