Description

Technical Field

[0001] This utility model relates to the field of pesticide production technology, specifically to a multi-stage filtration and adsorption device for CCMP waste gas treatment. Background Technology

[0002] In the process of pesticide production, the generation of CCMP exhaust gas is a common problem that needs to be solved. CCMP exhaust gas usually contains a variety of harmful substances. If it is directly discharged into the atmosphere, it will cause serious pollution to the environment and may also harm human health.

[0003] Currently, existing CCMP exhaust gas treatment devices have some shortcomings in actual operation. Among them, the exhaust fan, as a key component in the exhaust gas treatment process, needs to work continuously to ensure the effective extraction and transportation of exhaust gas. However, CCMP exhaust gas is usually high-temperature gas, and long-term high-temperature operation can easily lead to damage to the exhaust fan. This not only increases the maintenance cost and replacement frequency of the equipment, but may also affect the normal operation of the entire exhaust gas treatment system, resulting in a decrease in exhaust gas treatment efficiency. Utility Model Content

[0004] In view of the problems existing in the current multi-stage filtration and adsorption devices for CCMP exhaust gas treatment, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a multi-stage filtration and adsorption device for CCMP waste gas treatment, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-stage filtration and adsorption device for CCMP exhaust gas treatment includes vertical plates and a fixed shell. The fixed shell is fixedly disposed between two vertical plates. A first filter plate and a second filter plate are arranged sequentially from bottom to top on the lower inner side of the fixed shell. A first adsorption plate and a second adsorption plate are arranged sequentially from bottom to top on the upper inner side of the fixed shell. An air inlet is opened on the lower side of the fixed shell, and an air inlet shell is fixedly disposed below the air inlet. An air outlet is opened on the upper side of the fixed shell, and an air outlet shell is fixedly disposed above the air outlet. An exhaust fan is slidably disposed on the inner side of both the air inlet shell and the air outlet shell. A transmission mechanism for driving the exhaust fan is disposed on both sides of the fixed shell. An opening is opened on the front side of the fixed shell, and a closing mechanism is disposed on the outer side of the opening.

[0008] Preferably, the transmission mechanism includes a push plate and a hydraulic cylinder. The two hydraulic cylinders are fixedly disposed on the upper and lower sides of the fixed housing. The push plate is fixedly disposed at the end of the piston rod of the hydraulic cylinder. The exhaust fan is fixedly disposed on both sides near the push plate with a first sealing plate and a second sealing plate respectively. The push plate is fixedly disposed on the side near the first sealing plate with two connecting rods. One end of the plurality of connecting rods extends into the interior of the corresponding air inlet housing and air outlet housing respectively. One end of the plurality of connecting plates is fixedly connected to the corresponding first sealing plate respectively.

[0009] Preferably, the closing mechanism includes a cover plate and a limiting frame. The cover plate is abutted on the outside of the opening. Both sides of the lower end of the cover plate are hinged to the fixed shell. The limiting frame is movably sleeved on the outside of the fixed shell. The inner wall of the limiting frame abuts against the side of the cover plate away from the fixed shell. A side plate is fixedly provided on one side of the upper end of the fixed shell. A threaded rod is threaded into the inside of the side plate. The lower end of the threaded rod is rotatably connected to the fixed frame.

[0010] Preferably, a limiting block is fixedly provided on the outer wall of the fixed shell on the side away from the side plate, and a sliding rod is movably sleeved inside the limiting block, with the lower end of the sliding rod fixedly connected to the fixed frame.

[0011] Preferably, the walls of the plurality of connecting rods are movably fitted with bellows, and the two ends of the plurality of bellows are respectively fixedly connected to the outer wall of the corresponding air inlet shell, the outer wall of the air outlet shell, and the side wall of the push plate.

[0012] Preferably, a sealing ring is provided on the side of the cover plate near the fixed shell.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model employs two exhaust fans that work alternately, with the transmission mechanism driving the exhaust fans to switch working states. This avoids a single exhaust fan operating in a high-temperature exhaust gas environment for an extended period of time, effectively reducing the probability of exhaust fan damage due to high temperature, extending the service life of the exhaust fans, reducing equipment maintenance costs and replacement frequency, and ensuring the continuous and stable operation of the exhaust gas treatment system.

[0015] 2. This utility model, by setting up a multi-stage filtration and adsorption structure, has a first filter plate and a second filter plate inside the fixed shell that can filter large particulate impurities and some small particulate pollutants in CCMP exhaust gas. The first adsorption plate and the second adsorption plate can further adsorb harmful substances in the exhaust gas. The multi-stage treatment method improves the efficiency and quality of exhaust gas treatment, making the emitted exhaust gas more in line with environmental protection standards.

[0016] 3. This utility model, through the design of the closed mechanism, facilitates the replacement and maintenance of the filter plate and adsorption plate inside the fixed shell. By rotating the threaded rod, the limiting frame can be moved up and down, thereby realizing the limiting and unlocking of the cover plate. The operation is simple and convenient. At the same time, the sealing ring on the cover plate and the bellows on the connecting rod improve the sealing performance of the device, prevent exhaust gas leakage, and ensure the safety of the working environment.

[0024] This utility model discloses a multi-stage filtration and adsorption device for treating CCMP exhaust gas.

[0025] Reference Figure 1-3A multi-stage filtration and adsorption device for treating CCMP exhaust gas includes a vertical plate 1 and a fixed shell 2. The fixed shell 2 is fixedly disposed between two vertical plates 1. A first filter plate 3 and a second filter plate 4 are arranged sequentially from bottom to top on the lower inner side of the fixed shell 2. A first adsorption plate 5 and a second adsorption plate 6 are arranged sequentially from bottom to top on the upper inner side of the fixed shell 2. An air inlet is opened on the lower side of the fixed shell 2, and an air inlet shell 7 is fixedly disposed below the air inlet. An air outlet is opened on the upper side of the fixed shell 2, and an air outlet shell 8 is fixedly disposed above the air outlet. An exhaust fan 11 is slidably disposed on the inner side of both the air inlet shell 7 and the air outlet shell 8.

[0026] Reference Figure 1-3 The fixed shell 2 is provided with a transmission mechanism on both sides to drive the exhaust fan 11 to move. The transmission mechanism includes a push plate 10 and a hydraulic cylinder 9. The two hydraulic cylinders 9 are fixedly installed on the upper and lower sides of the fixed shell 2. The push plate 10 is fixedly installed at the end of the piston rod of the hydraulic cylinder 9. The exhaust fan 11 is fixedly installed with a first sealing plate 13 and a second sealing plate 12 on both sides near the push plate 10. Two connecting rods 14 are fixedly installed on the side of the push plate 10 near the first sealing plate 13. One end of the multiple connecting rods 14 extends into the interior of the corresponding air inlet shell 7 and air outlet shell 8. One end of the multiple connecting rods 14 is fixedly connected to the corresponding first sealing plate 13. The rod walls of the multiple connecting rods 14 are movably sleeved with bellows 15. The two ends of the multiple bellows 15 are fixedly connected to the outer wall of the corresponding air inlet shell 7, the outer wall of the air outlet shell 8 and the side wall of the push plate 10, respectively, to improve the sealing between the connecting rods 14 and the fixed shell 2.

[0027] Reference Figure 1-3 The front side of the fixed shell 2 has an opening, and a closing mechanism is provided on the outside of the opening. The closing mechanism includes a cover plate 16 and a limiting frame 17. The cover plate 16 is abutted on the outside of the opening. Both sides of the lower end of the cover plate 16 are hinged to the fixed shell 2 by hinges. The limiting frame 17 is movably sleeved on the outside of the fixed shell 2. The inner wall of the limiting frame 17 abuts against the side of the cover plate 16 away from the fixed shell 2. A side plate 18 is fixedly provided on one side of the upper end of the fixed shell 2. A threaded rod 19 is threaded inside the side plate 18. The lower end of the threaded rod 19 is rotatably connected to the limiting frame 17. A limiting block 21 is fixedly provided on the outer wall of the fixed shell 2 on the side away from the side plate 18. A sliding rod 20 is movably sleeved inside the limiting block 21. The lower end of the sliding rod 20 is fixedly connected to the limiting frame 17, so that the limiting frame 17 can slide stably. A sealing ring is provided on the side of the cover plate 16 near the fixed shell 2 to improve the sealing between the cover plate 16 and the fixed shell 2.

[0028] In this invention, during use, CCMP exhaust gas enters the fixed shell 2 through the inlet shell 7. It first passes through the first filter plate 3 and the second filter plate 4, where large particles and some small particles are filtered, resulting in preliminary purification. Next, the exhaust gas continues to rise, passing through the first adsorption plate 5 and the second adsorption plate 6, where harmful substances are further adsorbed. During the exhaust gas treatment process, one of the exhaust fans 11 is activated to discharge the treated exhaust gas through the outlet shell 8. After the exhaust fan 11 has been operating for a period of time, the hydraulic cylinder 9 is activated, and the piston rod of the hydraulic cylinder 9 pushes the push plate 10 to move. The push plate 10 drives the exhaust fan 11 to move via the connecting rod 14, causing the working exhaust fan 11 to exit the working position and another exhaust fan 11 to enter the working position and start working, realizing the alternating operation of the two exhaust fans 11. When it is necessary to replace or maintain the filter plate and adsorption plate inside the fixed shell 2, rotate the threaded rod 19 to move the limit frame 17 upward, release the limit on the cover plate 16, and then open the cover plate 16 to carry out the operation. After the operation is completed, close the cover plate 16, rotate the threaded rod 19 in the opposite direction to move the limit frame 17 downward, and re-limit the cover plate 16 to ensure the sealing of the device.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
