DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1-Figure 7As shown, the present invention provides a cleaning device for a feed production waste gas purification tank, comprising a purification tank body 10, an adjustment component 20, a cleaning component 30 and a filter component 40. Through the setting of the filter component 40, the toxic gas generated in the feed production process can be effectively filtered and purified, so that the discharged gas meets the requirements. The cleaning component 30 and the filter component 40 are adjusted up and down by the adjustment component 20, so as to facilitate better filtering of the toxic gas; the purification tank body 10 is provided with a waste gas treatment section 10a and a waste liquid treatment section 10b, and the outer wall of the waste gas treatment section 10a near the waste liquid treatment section 10b is provided with an air inlet pipe 11, and the top of the waste gas treatment section 10a away from the air inlet pipe 11 is provided with an air outlet pipe 12, and the waste liquid treatment section 10b is provided with an air outlet pipe 12. A liquid inlet pipe 13 is arranged on the outer wall of the waste gas treatment section 10b close to the waste gas treatment section 10a, and a liquid outlet pipe 14 is arranged at the bottom of the waste liquid treatment section 10b. The waste liquid treatment section 10b is funnel-shaped, and a V-shaped slope is arranged on its inner wall. The V-shaped slope can guide the waste liquid to flow more smoothly inside the waste liquid treatment section 10b. Due to the inclination angle of the slope, the waste liquid will flow rapidly along the slope to the liquid outlet pipe 14 of the waste liquid treatment section 10b under the action of gravity, reducing the retention time of the waste liquid in the bucket, thereby improving the efficiency of waste liquid treatment. The V-shaped slope inside the waste liquid treatment section 10b also helps to balance the distribution of the waste liquid in the bucket, reduce the center of gravity deviation caused by the accumulation of waste liquid, thereby improving the overall stability of the equipment, and valves are arranged on both the liquid inlet pipe 13 and the liquid outlet pipe 14.

[0018] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the adjustment component 20 includes an annular base 21, a rotating cylinder 22, a main gear 23, a slave gear 24 meshing with the main gear 23, and a motor 25; an inner wall of the annular base 21 is provided with an internal thread, one side of the annular base 21 is fixedly connected to the top center of the purification tank body 10, and the other side of the annular base 21 is provided with a T-shaped groove, and a T-shaped slider 22a adapted to the T-shaped groove is provided at the bottom of the rotating cylinder 22. The rotating cylinder 22 is slidably connected to the annular base 21 through the T-shaped slider 22a and the T-shaped groove. By providing the T-shaped slider 22a and the T-shaped groove, the rotating cylinder 22 can be rotated on the top of the annular base 21 to prevent the rotating cylinder 22 from being separated from the annular base 21. A movable groove 22b is provided on the inner wall of the rotating cylinder 22, and the top of the rotating cylinder 22 is fixedly connected to one side of the slave gear 24, and the main gear 23 is fixedly connected to the output end of the motor 25.

[0019] like Figure 2 and Figure 6As shown, the cleaning assembly 30 includes a cleaning pipe 31, two rotating blocks 32, a limiting cross bar 33 and two scrapers 34; the cleaning pipe 31 is provided with a water inlet section 31a, a threaded section 31b and a water spraying section 31c in sequence, the threaded section 31b passes through the top center of the purification tank body 10 and is threadedly connected to the inner wall of the annular base 21, and the rotating blocks 32 are symmetrically fixedly installed on both sides of the water inlet section 31a close to the threaded section 31b. By providing the rotating blocks 32, the adjustment assembly 20 realizes the rotation of the cleaning pipe 31 by rotating the rotating blocks 32 while moving up and down. The rotating cylinder 22 is rotatably connected to the water inlet section 31a of the cleaning pipe 31 through the moving groove 22b and the rotating block 32. The rotating block 32 is slidably connected to the moving groove 22b as the cleaning pipe 31 moves. By providing the moving groove 22b, not only the rotation of the rotating cylinder 22 is realized, but also the movement of the rotating block 32 is provided. The cleaning tube 31 is then moved to the left of the cleaning tube 31 and the cleaning tube 31 is moved to the right of the cleaning tube 31. The cleaning tube 31 is then moved to the right of the cleaning tube 31 and the cleaning tube 31 is moved to the right of the cleaning tube 31.

[0020] like Figure 6As shown, the cleaning assembly 30 also includes a movable ring 35 and a limiting ring 36. A water flow channel is provided in the cleaning pipe 31. The movable ring 35 is provided in the water inlet section 31a and is slidably connected to the inner wall of the water inlet section 31a. A water pipe is fixedly connected to the movable ring 35. A plurality of atomizing nozzles 31d are provided near the bottom of the water spraying section 31c. The limiting ring 36 is fixedly sleeved at the position of the water spraying section 31c near the threaded section 31b. By providing the limiting ring 36, the cleaning pipe 31 can be prevented from being separated when rising, and the filter assembly 40 can also be limited. The filter assembly 40 includes a connecting ring 41, a sliding ring 4 2. A plurality of baffles 43, a plurality of connecting plates 44 and a conical filter cloth 45. The inner walls of the connecting ring 41 and the sliding ring 42 are slidably sleeved with the outer surface of the water spray section 31c. One end of the baffle 43 is fixed on the connecting ring 41, and the other end of the baffle 43 is fixed on the sliding ring 42. The baffle 43 corresponds to the atomizing nozzle 31d. The baffle 43 effectively blocks the atomizing nozzle 31d to avoid waste of water. One end of the connecting plate 44 is evenly fixed on the side of the connecting ring 41 adjacent to the baffle 43, and the other end of the connecting plate 44 is fixedly connected to the large end of the conical filter cloth 45. By setting the conical filter cloth 45 into a conical shape, the contact area between the conical filter cloth 45 and the toxic gas is effectively increased, and the toxic gas generated in the feed production process can be effectively filtered and purified, so that the discharged gas meets the requirements. The atomizing nozzle 31d is located in the concave area of ​​the conical filter cloth 45, which can ensure that the flushing water flow can directly act on the surface of the conical filter cloth 45 and the concave part below it, ensuring that all parts of the conical filter cloth 45 can be fully flushed, preventing local blockage or reduced filtration efficiency due to inadequate flushing. The design of the atomizing nozzle 31d makes the water flow It is sprayed in the form of mist. This atomized flushing method can cover the surface of the conical filter cloth 45 more evenly and improve the flushing effect. At the same time, the mist water flow can more effectively penetrate into the fiber gaps of the conical filter cloth 45 to remove trapped impurities. Adjacent connecting plates 44 form fan-shaped flow areas. The fan-shaped flow areas can make the exhaust gas contact more fully when passing through the conical filter cloth 45, which helps to more effectively adsorb harmful substances in the exhaust gas, thereby improving the purification effect and facilitating better discharge of the exhaust gas after filtration. The small mouth end of the conical filter cloth 45 is provided with a bottom ring 45a that is slidably sleeved with the water spray section 31c.

[0021] When the present invention is in use, the dusty waste gas generated in the feed production process is sent into the purification tank body 10 through the air inlet pipe 11. During the rising process, the waste gas is filtered through the conical filter cloth 45. The clean gas filtered by the conical filter cloth 45 is discharged from the air outlet pipe 12 at the top of the purification tank body 10, so as to achieve the purpose of purifying the waste gas. When there is no or a small amount of impurities in the conical filter cloth 45, the waste gas can be filtered through the conical filter cloth 45, and the bottom ring 45a at the lower end of the conical filter cloth 45 contacts the upper surface of the limiting cross bar 33. At this time, the baffle plate 43 blocks the atomizing nozzle 31d, and the water flow cannot be sprayed out through the atomizing nozzle 31d. When the conical filter cloth 45 adsorbs impurities and there are too many impurities, the conical filter cloth 45 adsorbs impurities. The conical filter cloth 45 will slide upward under the action of the exhaust gas, so that the connecting plate 44 drives the connecting ring 41 and the baffle 43 on the connecting ring 41 and the sliding ring 42 fixedly connected to the baffle 43 to slide upward as a whole, thereby releasing the restriction of the baffle 43 on the atomizing nozzle 31d, and the water flow cleans the conical filter cloth 45 through the atomizing nozzle 31d until the impurities at the filter holes of the conical filter cloth 45 are cleaned up. After the impurities at the filter holes of the conical filter cloth 45 are cleaned up, the overall gravity of the filter assembly 40 is greater than the force of the exhaust gas, thereby causing the filter assembly 40 to slide downward as a whole until the baffle 43 blocks the atomizing nozzle 31d again, thereby filtering and purifying the exhaust gas again.

[0022] However, if the inner wall of the purification tank body 10 is not cleaned regularly, the filtering effect of the exhaust gas will be affected over time. In order to regularly clean the conical filter cloth 45 and the impurities on the inner wall of the purification tank body 10, the main gear 23 is driven by the motor 25, and then the slave gear 24 and the rotating cylinder 22 are driven to rotate. The moving groove 22b opened on the inner wall of the rotating cylinder 22 drives the rotating block 32 to rotate, and the internal thread of the inner wall of the annular base 21 is threadedly connected with the threaded section 31b on the cleaning tube 31, so that the cleaning tube 31 rotates and moves upward as a whole, thereby driving the scraper 34 at the bottom of the cleaning tube 31 to scrape the inner wall of the purification tank body 10, and at the same time driving the conical filter cloth 45 to move up and down, so that the conical filter cloth 45 is cleaned more cleanly, ensuring that the conical filter cloth 45 and the inside of the purification tank body 10 are clean and tidy, preventing blockage and reducing the purification efficiency, and facilitating the subsequent filtering and purification of toxic gases.

[0023] The present invention is also provided with a liquid inlet pipe 13, which can inject clean water into the purification tank body 10, and can effectively wash the impurities scraped off the purification tank 10 and the impurities washed off the conical filter cloth 45 into the waste liquid treatment section 10b. Through the waste liquid treatment section 10b, the impurities scraped off the purification tank body 10 and the waste water generated when cleaning the conical filter cloth 45 can be effectively discharged in time through the liquid outlet pipe 14, avoiding the accumulation of waste water, ensuring the clean environment inside the purification tank body 10, and improving the effect of exhaust gas purification to a certain extent.

[0024] like Figure 1 As shown, the cleaning equipment also includes a mounting bracket 50, which includes a plurality of fixing columns 51 and a fixing ring 52. The inner wall of the fixing ring 52 is fixedly sleeved on the outer surface of the purification tank body 10, and the side of the fixing ring 52 adjacent to the purification tank body 10 is fixedly mounted on one end of the plurality of fixing columns 51 to facilitate the fixation of the purification tank body 10.
