Description

Technical Field

[0001] This utility model belongs to the field of metal cleaning agent production technology, and specifically relates to a waste gas purification mechanism for metal cleaning agent production. Background Technology

[0002] The production process of metal cleaning agents generates a large amount of waste gas containing various harmful components. This waste gas usually contains acidic or alkaline harmful gases, solid impurity particles, and other pollutants that are difficult to treat. If these waste gases are directly discharged into the atmosphere, they will cause serious pollution to the surrounding environment, harm the ecological balance, and also pose a great threat to human health, potentially causing respiratory diseases, cardiovascular diseases, and other health problems.

[0003] Traditional waste gas treatment methods typically involve simple spraying equipment. Due to unreasonable spray structure design, the contact area between the cleaning liquid and the waste gas is limited, making it impossible to fully remove harmful components from the waste gas. Furthermore, it lacks effective treatment for residual microparticles and unreacted harmful components in the waste gas. When filtering impurities, the filter device is prone to clogging, and the collection and cleaning of filtered impurities is not convenient, requiring the equipment to be disassembled for cleaning, which is difficult and affects the normal operation and processing efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste gas purification mechanism for the production of metal cleaning agents.

[0005] To achieve the above objectives, this utility model provides a waste gas purification mechanism for the production of metal cleaning agents, including a spray cylinder. An air inlet pipe is connected to the lower part of one side of the spray cylinder, and a liquid pump is connected to the lower part of one side of the spray cylinder. The input end of the liquid pump extends through into the interior of the spray cylinder, and the output end of the liquid pump is connected to a delivery pipe. A spray pipe is connected to the upper end of the delivery pipe, and one end of the spray pipe extends through into the interior of the spray cylinder. The spray pipe is located above the inner wall of the spray cylinder and is arranged in a cross shape. An adsorption plate is connected to the upper end of the inner wall of the spray cylinder, and an air outlet pipe is connected to the middle of the upper end of the spray cylinder. A filter assembly is connected to the inner wall of the spray cylinder below the air inlet pipe, and a cleaning assembly is connected to the lower part of one side of the spray cylinder.

[0006] In the above technical solution, the filter assembly further includes a filter plate, the filter plate is V-shaped, a feed cylinder is connected to the middle of the lower end of the filter plate, a housing is connected to the upper part of one side of the spray cylinder, a motor is connected to the middle of the lower end of the housing, the output end of the motor extends through into the interior of the housing, a gear is connected to the middle of the outer wall of the motor output end, and the gear is located inside the housing.

[0007] In the above technical solution, one end of the gear extends through into the interior of the spray cylinder, and a gear ring is meshed with one side of the gear. Scrapers are connected to both sides of the inner wall of the gear ring, and the lower ends of the two scrapers respectively contact the upper sides of the filter plate.

[0008] In the above technical solution, a stabilizing ring is further connected to the inner wall of the spray cylinder above the toothed ring, and stabilizing blocks are connected to both sides of the upper end of the toothed ring. A stabilizing groove is opened at the lower end of the stabilizing ring corresponding to the two stabilizing blocks. The two stabilizing blocks slide inside the stabilizing groove, and the upper end of the stabilizing ring is inclined.

[0009] In the above technical solution, the cleaning component further includes a cylinder, one end of which extends through into the interior of the spray cylinder, and a movable block is connected to one end of the cylinder. A guide rod is connected to one side of the inner wall of the spray cylinder corresponding to the side of the movable block, and the movable block slides on the outer wall of the guide rod.

[0010] In the above technical solution, the upper end of the movable block is rotatably connected to a support rod, the upper end of the support rod is rotatably connected to a movable plate, and the upper middle part of the movable plate is threaded with a collecting cylinder, which is a mesh-like structure.

[0011] In the above technical solution, a threaded ring is further connected to the upper end of the movable plate corresponding to the collecting cylinder, the lower part of the outer wall of the collecting cylinder is threaded, and the collecting cylinder is threadedly connected to the threaded ring.

[0012] In the above technical solution, a connecting rod is further connected to the middle of the lower end of the inner wall of the collecting cylinder. The connecting rod is located inside the feeding cylinder. A scraper ring is connected to the upper end of the connecting rod. The lower end of the scraper ring is inclined. The shape of the outer wall of the scraper ring is adapted to the shape of the inner wall of the feeding cylinder.

[0013] In the above technical solution, further, the upper end of the movable plate is evenly provided with guide holes, and the number of guide holes is three sets. The inner wall of the guide holes is connected with a sliding rod, and the lower end of the multiple sliding rods is connected to the lower end of the inner wall of the spray cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The motor drives the gear to rotate, and the gear meshes precisely with the gear ring, causing the gear ring to rotate smoothly. This, in turn, drives the scrapers on both sides of the inner wall to operate synchronously. This transmission method ensures that the scrapers can clean the filter plate accurately and efficiently, completely scraping the impurities intercepted on the filter plate into the feed cylinder, which facilitates the cleaning of the filter plate and the collection of impurities at the cleaning point.

[0016] When it is necessary to clean the accumulated impurities in the feed cylinder, the cylinder pulls the moving block to slide smoothly along the guide rod. The moving block cleverly drives the moving plate to move through the support rod, so that the collecting cylinder moves below the feed cylinder. During the movement, the scraper ring inside the collecting cylinder thoroughly scrapes off the impurities attached to the inner wall of the feed cylinder. The impurities fall into the collecting cylinder, which can process and collect the impurities inside the feed cylinder. The collecting cylinder and the moving plate are connected by threads, which makes it easy to install and disassemble the collecting cylinder, greatly saving the time of cleaning impurities, improving the efficiency of the overall cleaning work, and ensuring that the equipment can be quickly restored to normal operation.

[0025] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-7The exhaust gas purification mechanism for a metal cleaning agent production shown includes a spray cylinder 1, an air inlet pipe 2 connected to the lower part of one side of the spray cylinder 1, a liquid pump 3 connected to the lower part of one side of the spray cylinder 1, the input end of the liquid pump 3 extending through into the interior of the spray cylinder 1, the output end of the liquid pump 3 connected to a delivery pipe 4, the upper end of the delivery pipe 4 connected to a spray pipe 5, one end of the spray pipe 5 extending through into the interior of the spray cylinder 1, the spray pipe 5 being located above the inner wall of the spray cylinder 1, the spray pipe 5 being arranged in a cross shape, an adsorption plate 6 connected to the upper end of the inner wall of the spray cylinder 1, an air outlet pipe 7 connected to the middle of the upper end of the spray cylinder 1, a filter assembly connected to the inner wall of the spray cylinder 1 below the air inlet pipe 2, and a cleaning assembly connected to the lower part of one side of the spray cylinder 1.

[0027] A liquid inlet pipe is connected to one side of the spray cylinder 1, and a liquid outlet pipe is connected to the same side of the spray cylinder 1. The liquid pump 3 draws out the cleaning liquid from the bottom of the spray cylinder 1 and delivers it to the inside of the spray pipe 5 through the delivery pipe 4. The spray pipe 5 sprays the cleaning liquid evenly inside the spray cylinder 1, allowing it to come into full-range and large-area contact with the rising exhaust gas, significantly improving the efficiency and effect of the purification reaction. The exhaust gas continues to rise and is adsorbed by the adsorption plate 6. The gas is then discharged through the exhaust pipe 7, which is usually equipped with an exhaust gas concentration monitor, flow control valve, and other equipment to monitor the exhaust gas emission indicators in real time and accurately control the emission flow rate to ensure that the exhaust gas emission is under effective monitoring throughout the process. A connecting door is opened at the bottom of one side of the spray cylinder 1 to facilitate the cleaning of the collection cylinder 20.

[0028] The filter assembly includes a filter plate 8, which is V-shaped. A feed cylinder 9 is connected to the middle of the lower end of the filter plate 8. A housing 10 is connected to the upper part of one side of the spray cylinder 1. A motor 11 is connected to the middle of the lower end of the housing 10. The output end of the motor 11 extends through into the interior of the housing 10. A gear 12 is connected to the middle of the outer wall of the output end of the motor 11. The gear 12 is located inside the housing 10. One end of the gear 12 extends through into the interior of the spray cylinder 1. A gear ring 13 is meshed with one side of the gear 12. Scrapers 14 are connected to both sides of the inner wall of the gear ring 13. The lower ends of the two scrapers 14 contact the upper sides of the filter plate 8 respectively. A stabilizing ring is connected to the inner wall of the spray cylinder 1 above the gear ring 13. Stabilizing blocks are connected to both sides of the upper end of the gear ring 13. Stabilizing grooves are opened at the lower end of the stabilizing ring corresponding to the two stabilizing blocks. The two stabilizing blocks slide inside the stabilizing grooves. The upper end of the stabilizing ring is inclined.

[0029] When the water mist carries the captured impurity particles and some of the cleaning fluid downwards, the V-shaped structure greatly expands the contact area between the filter plate 8 and the falling material, which greatly improves the interception efficiency. Furthermore, the impurities can naturally and smoothly slide down the inclined slope of the filter plate 8 into the feed cylinder 9 connected to the lower middle part of the filter plate 8. The feed cylinder 9 can collect the impurities.

[0030] When it is necessary to clean the filter plate 8, the motor 11 in the middle of the lower end of the upper shell 10 on one side of the spray cylinder 1 starts to run. The motor 11 drives the gear 12 to rotate, and the gear ring 13 starts to rotate under the drive of the gear 12. The scraper 14 rotates synchronously with the gear ring 13, scraping the impurities intercepted on both sides of the upper end of the filter plate 8 down to the feed cylinder 9. The stabilizing ring set on the inner wall of the spray cylinder 1 above the gear ring 13 works in coordination with the stabilizing blocks connected to both sides of the upper end of the gear ring 13. The stabilizing blocks slide smoothly in the stabilizing groove opened at the lower end of the stabilizing ring, ensuring that the gear ring 13 rotates smoothly without shaking.

[0031] The cleaning assembly includes a cylinder 15, one end of which extends into the interior of the spray cylinder 1. A movable block 16 is connected to one end of the cylinder 15. A guide rod 17 is connected to one side of the inner wall of the spray cylinder 1, corresponding to the side of the movable block 16. The movable block 16 slides on the outer wall of the guide rod 17. A support rod 18 is rotatably connected to the upper end of the movable block 16. A movable plate 19 is rotatably connected to the upper end of the support rod 18. A collection cylinder 20 is threadedly connected to the middle of the upper end of the movable plate 19. The collection cylinder 20 is mesh-like. A threaded connection is made to the upper end of the movable plate 19 corresponding to the collection cylinder 20. The lower part of the outer wall of the collection cylinder 20 is threaded, and the collection cylinder 20 is threadedly connected to the threaded ring. A connecting rod 21 is connected to the middle of the lower end of the inner wall of the collection cylinder 20. The connecting rod 21 is located inside the feeding cylinder 9. A scraper ring 22 is connected to the upper end of the connecting rod 21. The lower end of the scraper ring 22 is inclined. The shape of the outer wall of the scraper ring 22 is adapted to the shape of the inner wall of the feeding cylinder 9. Guide holes are evenly opened at the upper end of the moving plate 19. There are three sets of guide holes. A sliding rod 23 is connected to the inner wall of the guide hole. The lower ends of the multiple sliding rods 23 are connected to the lower end of the inner wall of the spray cylinder 1.

[0032] The guide rod 17 provides stable guidance for the sliding of the moving block 16, ensuring that the moving block 16 can move along the predetermined trajectory. The support rod 18 rotating at the upper end of the moving block 16 can convert the linear motion of the moving block 16 into the up-and-down motion of the moving plate 19. The upper middle part of the moving plate 19 is threadedly connected to the collecting cylinder 20, which is a mesh structure. This mesh structure can ensure that impurities can enter the collecting cylinder 20 smoothly. The collecting cylinder 20 is threadedly connected to the threaded ring. This threaded connection method makes the installation and disassembly of the collecting cylinder 20 very convenient and facilitates the periodic cleaning of impurities. When the scraper ring 22 moves, it can completely scrape off the impurities on the inner wall of the feeding cylinder 9. Multiple sliding rods 23 further ensure the stability of the moving plate 19 and prevent it from shaking and deviating during the movement.

[0033] Working principle: The waste gas generated during the production of metal cleaning agent enters the spray cylinder 1 through the inlet pipe 2. After entering the spray cylinder 1, the waste gas moves upward. The cleaning liquid is stored at the lower end of the spray cylinder 1. The liquid pump 3 starts to work, drawing the cleaning liquid inside the spray cylinder 1 from its input end and transporting it to the spray pipe 5 through the delivery pipe 4. The spray pipe 5 has a cross-shaped structure and is located above the inner wall of the spray cylinder 1. The cleaning liquid is sprayed out from the spray pipe 5, forming a mist or droplets. The rising waste gas comes into full contact with the sprayed cleaning liquid, and the harmful components in the waste gas react physically or chemically with the cleaning liquid.

[0034] After being sprayed, some harmful components of the exhaust gas have been removed, but some tiny particles or unreacted harmful components may still remain. At this time, the exhaust gas continues to flow upward and rises to the adsorption plate 6 connected to the upper end of the inner wall of the spray cylinder 1. The adsorption plate 6 will further adsorb the residual harmful components or tiny particles in the exhaust gas. Through physical adsorption or chemical adsorption, these substances are attached to the surface of the adsorption plate 6, so that the exhaust gas is more thoroughly purified. After a series of purification treatments such as spraying and adsorption, the exhaust gas is discharged from the exhaust pipe 7 connected to the middle of the upper end of the spray cylinder 1 and enters the subsequent emission or treatment stage to ensure that the discharged exhaust gas meets the relevant environmental protection standards.

[0035] When the water mist comes into contact with the upward-flowing exhaust gas, on the one hand, the harmful components in the exhaust gas will undergo physical or chemical reactions with the cleaning liquid. For example, acidic or alkaline harmful gases may neutralize with the corresponding components in the cleaning liquid, thereby being removed or absorbed. On the other hand, the water mist has a certain degree of adhesion and can capture solid impurity particles in the exhaust gas. These impurity particles, which are adhered to by the water mist, increase in weight and begin to fall under the action of gravity. The falling impurities move downward along with some of the cleaning liquid. The filter plate 8 can effectively intercept the falling impurities. The impurities will slide down the inclined surface of the filter plate 8 into the feed cylinder 9 connected to the middle of the lower end of the filter plate 8. The cleaning liquid can flow back to the bottom of the spray cylinder 1 through the gaps or holes of the filter plate 8 so that the liquid pump 3 can extract and reuse it again.

[0036] When it is necessary to clean the impurities on the filter plate 8, the motor 11 is started. The output end of the motor 11 rotates, which drives the gear 12 connected to the middle of the outer wall of its output end to rotate. One end of the gear 12 extends through into the interior of the spray cylinder 1, and a gear ring 13 is meshed on one side of the gear 12. Therefore, the rotation of the gear 12 will drive the gear ring 13 to rotate. The scrapers 14 connected to both sides of the inner wall of the gear ring 13 will rotate with the rotation of the gear ring 13. The lower end of the scraper 14 contacts the upper sides of the filter plate 8, thereby scraping the impurities intercepted on the filter plate 8 into the feed cylinder 9. The setting of the stabilizing ring and the stabilizing block ensures the stability of the gear ring 13 when it rotates. The upper end of the stabilizing ring is set in an inclined shape, so that the scraped impurities can slide more smoothly into the feed cylinder 9.

[0037] After a certain amount of impurities accumulate in the feed cylinder 9, the cleaning liquid inside the spray cylinder 1 is discharged. The cylinder 15 is activated, and the cylinder 15 pulls the moving block 16 to slide on the guide rod 17. The moving block 16 drives the moving plate 19 to move through the support rod 18, so that the collecting cylinder 20 sleeved on the outer wall of the feed cylinder 9 is moved to a suitable position, so that the connecting rod 21 is located inside the feed cylinder 9. The scraper ring 22 at the upper end of the connecting rod 21 scrapes the impurities off the inner wall of the feed cylinder 9. The impurities fall into the collecting cylinder 20 through the lower opening of the feed cylinder 9. After cleaning, the connecting door is opened, and the collecting cylinder 20 is rotated to separate it from the threaded ring. The collecting cylinder 20 is taken out and the impurities inside are cleaned. After cleaning, the collecting cylinder 20 is reinstalled, and the moving plate 19 is reset under the action of the cylinder 15. The guide hole and slide rod 23 on the moving plate 19 ensure the stability of the movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
