A water pool 13 for receiving the spray water is provided below the spray device 1. The water pool 13 is used to receive the waste water generated during the spraying process, including the captured particulate matter and other components in the waste gas. A scraping assembly 2 for scraping off the floating foam on the surface of the pool 13 is installed in the pool 13. The automatic scraping function of the scraping assembly 2 ensures the cleanliness of the surface of the pool 13 and avoids the potential damage of the floating foam to the equipment. At the same time, it also reduces the frequency and labor intensity of manual cleaning and improves the automation level of the equipment. An elastic component 3 for ejecting the floating foam attached to the scraping assembly 2 is installed on the scraping assembly 2. This design avoids the accumulation of floating foam on the scraping assembly 2 and ensures the continuous and effective operation of the scraping assembly 2. The introduction of the elastic component 3 enables the scraping assembly 2 to automatically clean itself while scraping the floating foam, thereby maintaining the continuity and stability of the scraping effect. A containing box 4 for containing floating foam is connected to one side of the pool 13. The containing box 4 is located at the outlet of the pool 13 and is used to contain the scraped floating foam.

[0034] In this embodiment: the scraping assembly 2 includes a power motor 21 fixedly installed on one side of the pool 13, the power output end of the power motor 21 passes through the side wall of the pool 13 and is fixedly connected to the first sprocket 22, the power motor 21 serves as the power source of the scraping assembly 2, drives the first sprocket 22 to rotate, the first sprocket 22 is transmission-connected with a chain 23, one end of the chain 23 is transmission-connected with a second sprocket 24, through the transmission of the chain 23, the rotational power of the power motor 21 is transmitted to the second sprocket 24, thereby driving the entire scraping assembly 2 to circulate on the side wall of the pool 13, the outlet of the pool 13 is at the end of the second sprocket 24, and the second sprocket 24 is connected to the pool The side wall of the pool 13 is rotatably connected, a fixed mounting block 25 is fixedly mounted on the chain 23, a sliding plate 26 is fixedly mounted on the fixed mounting block 25, a scraping plate 27 for scraping off floating foam on the water surface is slidably connected to the sliding plate 26, and directly contacts the floating foam on the surface of the pool 13, and scrapes off the floating foam and pushes it to the edge of the pool 13 through its sliding movement, and pushes it into the containing box 4, the fixed mounting block 25 provides a stable mounting base for the scraping plate 27, and allows the scraping plate 27 to slide on the sliding plate 26, and through the drive of the power motor 21 and the transmission of the chain 23, the scraping plate 27 can continuously and stably perform a scraping operation on the surface of the pool 13.

[0035] In this embodiment: a guide track 14 is opened on the side wall of the water pool 13, and the guide track 14 is located on the outside of the chain 23. A slope 15 is provided on the guide track 14, and the slope 15 is inclined toward the side wall of the water pool 13. This design improves the movement stability of the scraping component 2 and reduces the risk of reduced scraping effect or equipment damage due to shaking or deviation from the track. This design not only improves the movement stability and scraping effect of the scraping component 2 and the elastic component 3, but also extends the service life of the equipment and reduces maintenance costs, which is beneficial to improving the overall performance and environmental protection effect of the equipment.

[0036] In this embodiment: an inclined track 28 is installed above the chain 23, and the inclined track 28 is fixedly installed on the side wall of the pool 13 to form an inclined upward sliding path. A resisting block 29 is slidably connected to the inclined track 28, and the resisting block 29 is used to resist the scraping plate 27. A steel spring 210 is fixedly installed on one side of the resisting block 29, and the steel spring 210 is used to drive the resisting block 29 to return to its original position. The steel spring 210 is fixedly installed in the inclined track 28. The existence of the steel spring 210 enables the resisting block 29 to quickly return to its original position after each collision with the scraping plate 27, and to prepare for the next collision. This automatic reset mechanism ensures the continuity and stability of the scraping process. As the scraping plate 27 moves, it will conflict with the resisting block 29. When the scraping plate 27 is resisted to a fixed position, the resisting block 29 slides on the inclined track 28. A rack 211 is provided below the inclined track 28, and the rack 211 is fixedly installed on the side wall of the pool 13.

[0037] In this embodiment, the elastic component 3 includes a torsion spring 31 which is respectively fixedly connected to the two sections of the sliding plate 26. The two-stage rotation of the sliding plate 26 is realized by the driving action of the torsion spring 31. No additional driving mechanism is required, which simplifies the structure of the entire scraping component 2, reduces the manufacturing cost and maintenance difficulty. This design enables the sliding plate 26 to generate relative rotation when it is acted upon by the internal torsion spring 31, so that one end of the sliding plate 26 is bounced, which is more conducive to flicking off the floating foam attached to the scraping plate 27. A plurality of elastic blocks 35 for returning to the original position are fixedly connected, a gear rod 32 is rotatably connected in the middle of the torsion spring 31, a gear 33 is fixedly connected to one end of the gear rod 32, the gear 33 is used to mesh with the rack 211, and a round protrusion 34 is fixedly installed on the other end of the gear rod 32, the round protrusion 34 is used to contact with the elastic block 35, after the torsion spring 31 returns to the original position, when the round protrusion 34 is still in contact with the elastic block 35, the elastic block 35 will be squeezed and deformed after being contacted, and the round protrusion 34 can slide over the position of the elastic block 35, and the round protrusion 34 can slide over the position of the elastic block 35. After the block 34 slides over, the elastic block 35 returns to its original position under the action of elasticity, so that the gear rod 32 can continue to rotate. The gear rod 32 is rotatably connected to the sliding plate 26. One side of the gear rod 32 is provided with a control rod 38 on the sliding plate 26. The control rod 38 is used to abut against one side of the scraping plate 27. The scraping plate 27 can be prevented from sliding in the sliding plate 26 through the abutment of the control rod 38 against the scraping plate 27. The control rod 38 is slidably connected to the sliding plate 26. One end of the control rod 38 is fixedly connected to a sliding ball 39. The sliding ball 39 is fixed to the guide The track 14 and the slope 15 are slidably connected, and the design of the sliding ball 39 can prevent jamming during the sliding process. Through the design of the elastic component 3, when there is too much foam attached to the scraper plate 27, the foam attached to the scraper plate 27 can be bounced off by elastic force, thereby ensuring the continuity and efficiency of the scraping work. The design of the elastic component 3 plays a key role in the equipment, which not only improves the scraping efficiency and prolongs the service life of the equipment, but also simplifies the operation and maintenance process, providing a strong guarantee for the stable operation of the equipment.

[0038] In this embodiment, a slide groove 36 is provided in the sliding plate 26, and the scraper plate 27 is slidably connected to the slide groove 36. The slide groove 36 provided on the sliding plate 26 allows the scraper plate 27 to slide therein and provides a fixed sliding range for the sliding plate 26. This design enables the scraper plate 27 to slide according to actual conditions. A spring 37 is fixedly connected to one side of the scraper plate 27, and the spring 37 is fixedly installed in the sliding plate 26. When the scraper plate 27 is not interfered by the control rod 38, the scraper plate 27 is driven to slide on the slide groove 36 of the sliding plate 26 by the action of the spring 37. Due to the elastic force of the spring 37, the scraper plate 27 can slide quickly in the slide groove 36, so that the floating foam attached to the scraper plate 27 can be ejected, and the scraper plate 27 slides on the sliding The bouncing on the movable plate 26 can reduce the range of the space in front of the sliding plate 26, and can reduce the residual foam on the scraper plate 27, and can bounce off the residue on the scraper plate 27. At the same time, when the sliding plate 26 is rotated by the chain 23, while the scraper plate 27 ejects the residue, the sliding plate 26 drives the scraper plate 27 to swing downward together through the two-stage design of the sliding plate 26 and under the action of the torsion spring 31, which is more conducive to further throwing away the residual foam on the scraper plate 27 into the packaging box 4. The spring 37 is used to drive the scraper plate 27 to slide in the sliding plate 26. The elasticity of the spring 37 is less than the elasticity of the steel spring 210. This design enhances the adaptability and stability of the scraper plate 27, and is also conducive to improving the efficiency and performance of the entire scraper assembly 2.

[0039] The locking cam 312 is provided on one end of the locking cam 314 so as to enable the locking cam 312 to be unlocked and the locking cam 314 to be unlocked can be easily broken.

[0040] In this embodiment: the spraying device 1 includes a first spraying chamber 16 connected to the air inlet 11, so that the exhaust gas can smoothly enter the first spraying chamber 16, which provides a prerequisite for the subsequent treatment process. A plurality of spraying heads 17 for spraying water are installed above the first spraying chamber 16. The water sprayed by the spraying head 17 is used to capture particulate matter in the exhaust gas. The water mist sprayed by the spraying head 17 can fully contact with the incoming exhaust gas, and the particulate matter in the exhaust gas is captured by the adsorption effect of water droplets, thereby achieving the purpose of purifying the exhaust gas. A spiral blade 18 for driving the exhaust gas flow is provided below the spraying head 17. The design of the spiral blade 18 can drive The exhaust gas generates a rotating flow in the first spray chamber 16, which not only enhances the mixing effect of the exhaust gas and the spray water and improves the efficiency of capturing particulate matter, but also helps to distribute the particulate matter in the exhaust gas more evenly in the water mist. The first spray chamber 16 is connected to a transfer chamber 19 above. The design of the transfer chamber 19 enables the exhaust gas that has undergone preliminary treatment to smoothly enter the subsequent treatment stage, thereby ensuring the continuity of the entire treatment process. A water outlet 110 for discharging water is provided below the first spray chamber 16. The water outlet 110 can discharge the water accumulated in the first spray chamber 16 in time to prevent the water level from being too high and affecting the exhaust gas treatment effect.

[0041] In this embodiment: the transfer bin 19 is connected to an air pipe 111 for guiding the flow of exhaust gas below, and one end of the air pipe 111 is fixedly connected to a second spray bin 112. The second spray bin 112 has the same structure as the first spray bin 16, and the exhaust gas is guided to the next treatment stage through the air pipe 111. This design ensures the continuous flow of the exhaust gas and allows the exhaust gas to smoothly enter the second spray bin 112 for further treatment. The second spray bin 112 is configured to perform a secondary spray treatment on the exhaust gas to further remove the remaining particulate matter in the exhaust gas, which enhances the purification effect of the exhaust gas and ensures that the exhaust gas reaches a certain degree of cleanliness before subsequent treatment. An activated carbon block 113 for absorbing and filtering the exhaust gas is provided above the second spray bin 112. The activated carbon block 113 is located below the air outlet. The powerful adsorption capacity of the activated carbon block 113 can further absorb harmful substances in the exhaust gas, especially those trace gas components that are difficult to treat by spraying.

[0042] Working principle: First, turn on the spraying device 1 to guide the paint exhaust gas generated during the painting of the ammunition box into the first spray chamber 16 through the air inlet 11, and then spray the exhaust gas through the spray head 17, so that the particles in the paint exhaust gas are adsorbed by water and fall off, and at the same time, the spiral blades 18 drive the paint exhaust gas to rotate, so that the paint exhaust gas can be sprayed more fully, which can enhance the mixing effect of the paint exhaust gas and the spray water, so that the particles in the paint exhaust gas can be more evenly distributed in the water mist. After the water mist comes into contact with the particles in the paint exhaust gas, it will be discharged into the water pool 13 through the water outlet 110.

[0043] The paint exhaust gas after spraying will flow into the transfer bin 19, and then under the guidance of the air pipe 111, the paint exhaust gas will enter the second spray bin 112, and the paint exhaust gas will be sprayed for the second time to further remove the remaining particulate matter in the paint exhaust gas, which enhances the purification effect of the exhaust gas. The paint exhaust gas after the second spraying will then pass through the activated carbon block 113. The powerful adsorption capacity of the activated carbon block 113 can further absorb harmful substances in the exhaust gas, especially those trace gas components that are difficult to treat by spraying. The paint exhaust gas adsorbed by the activated carbon block 113 is then discharged through the exhaust port 12.

[0044] When the water in the paint exhaust gas is captured and flows into the pool 13, the water will generate foam when entering the pool 13, and the first sprocket 22 is driven to rotate by the power motor 21, and the second sprocket 24 is driven to rotate under the action of the chain 23, so that the fixed mounting block 25 fixedly mounted on the chain 23 moves together, and the sliding plate 26 and the scraping plate 27 fixedly mounted on the fixed mounting block 25 move together, and the floating foam on the surface of the pool 13 is scraped by the movement of the scraping plate 27, and the sliding ball 39 on the sliding plate 26 is driven to slide on the guide track 14 together with the control rod 38 when the movement, when the scraping plate 27 moves from one side of the pool 13 to the side close to the container 4, the fixed mounting block 25 is driven by the second sprocket 24 to move. The fixed mounting block 25 and the sliding plate 26 are tilted, and the floating foam scraped by the scraping plate 27 is pushed to the outlet of the pool 13 by the tilt of the sliding plate 26, and then pushed into the container 4. As the chain 23 continues to rotate, the sliding ball 39 on the control rod 38 enters the slope 15 on the guide track 14. Due to the design of the slope 15, the sliding ball 39 drives the control rod 38 to slide, so that the control rod 38 slides outside the sliding plate 26, so that the control rod 38 loses the resistance to the scraping plate 27. After the scraping plate 27 is no longer resisted by the control rod 38, the scraping plate 27 is driven by the spring 37 to bounce through the slide groove 36 in the sliding plate 26, so that the floating foam attached to the scraping plate 27 is bounced into the container 4.

[0045] When the scraper plate 27 bounces to the other end of the sliding plate 26 and contacts the resistance block 314, the resistance block 314 drives the resistance rod 311 to slide together, and at the same time causes the elastic spring 313 to deform. The elasticity of the elastic spring 313 is much smaller than the elasticity of the spring 37. When the resistance rod 311 slides, it drives the clamping strip 312 to slide out of the clamping groove 310. After the clamping strip 312 slides out of the clamping groove 310, the sliding plate 26 is bounced under the action of the torsion spring 31. Through the rebound again, the floating foam on the scraper plate 27 can be further bounced into the packaging box 4.

[0046] When the chain 23 drives the sliding plate 26 to move to the rack 211 through the fixed mounting block 25, the gear 33 meshes with the rack 211, and at the same time, the gear 33 drives the toothed rod 32 and the round protrusion 34 to rotate together through the gear 33, and the round protrusion 34 resists the elastic block 35, so that the torsion spring 31 rotates back and drives the two sections of the sliding plate 26 to return to their original positions. When the torsion spring 31 returns to its original position, the gear 33 is still rotating at this time. The elastic block 35 is resisted by the round protrusion 34, and the elastic block 35 is squeezed and deformed after being resisted. At this time, the round protrusion 34 can slide over the position of the elastic block 35, and the two sections of the sliding plate 26 produce a smaller vibration, so that the resistance rod 311, under the action of the elastic spring 313, drives the card strip 312 to be inserted into the card slot 310 to fix the two sections of the sliding plate 26.

[0047] As the chain 23 drives the fixed mounting block 25 to continue to move, the scraper plate 27 and the resisting block 29 are resisted. Since the elastic force of the steel spring 210 is greater than the elastic force of the spring 37, the scraper plate 27 is gradually resisted and the spring 37 is deformed. When the scraper plate 27 slides back to the normal position, when the spring 37 has been deformed to the limit position, as the sliding plate 26 continues to move, the resisting block 29 begins to slide in the inclined track 28, causing the steel spring 210 to deform. At the same time, as the sliding plate 26 continues to move, the sliding ball 39 slides back into the guide track 14. At this time, the sliding ball 39 drives the control rod 38 to slide back into the interior of the sliding plate 26, so that the control rod 38 is restored to the state of resisting the scraper plate 27. As the resisting block 29 slides obliquely upward, the resisting block 29 no longer resists the scraping plate 27. At this time, the scraping plate 27 slides over the resisting block 29. After the resisting block 29 is no longer resisted, it returns to its original position under the action of the steel spring 210. At this time, the scraping plate 27 continues to move under the action of the chain 23, thereby achieving the next scraping of the floating foam on the surface of the pool 13.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
