DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] As Figures 1-7As shown, the present application provides a cleaning device for feed production exhaust gas purification tank, which comprises a purification tank body 10, an adjusting assembly 20, a cleaning assembly 30 and a filtering assembly 40. The filtering assembly 40 can effectively filter and purify the toxic gas generated in the feed production process, so that the discharged gas meets the requirements. The adjusting assembly 20 adjusts the position of the cleaning assembly 30 and the filtering assembly 40, which facilitates 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. The outer wall of the waste gas treatment section 10a close to the waste liquid treatment section 10b is provided with an air inlet pipe 11. The top of the waste gas treatment section 10a away from the air inlet pipe 11 is provided with an air outlet pipe 12. The outer wall of the waste liquid treatment section 10b close to the waste gas treatment section 10a is provided with a liquid inlet pipe 13. The bottom of the waste liquid treatment section 10b is provided with a liquid outlet pipe 14. The waste liquid treatment section 10b is funnel-shaped and has a V-shaped slope 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 residence time of the waste liquid in the bucket and 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 waste liquid in the bucket, reducing the center of gravity deviation caused by waste liquid accumulation and improving the overall stability of the equipment. The liquid inlet pipe 13 and the liquid outlet pipe 14 are both provided with valves.

[0026] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 7 , the adjusting assembly 20 comprises a ring base 21, a rotating cylinder 22, a main gear 23, a slave gear 24 meshing with the main gear 23 and a motor 25.

The rotating cylinder 22 is slidingly connected to the ring base 21 through the T-shaped sliding block 22a and the T-shaped sliding groove. The T-shaped sliding block 22a and the T-shaped sliding groove allow the rotating cylinder 22 to rotate on the top of the ring base 21, preventing the rotating cylinder 22 from detaching from the ring base 21. The inner wall of the rotating cylinder 22 is provided with a moving groove 22b. The top of the rotating cylinder 22 is fixedly connected to one side of the slave gear 24. The main gear 23 is fixedly connected to the output end of the motor 25.

[0027] As shown in Figure 2 and Figure 6As shown, the cleaning assembly 30 comprises a cleaning pipe 31, two rotating blocks 32, a limiting cross rod 33 and two scrapers 34; the cleaning pipe 31 is sequentially provided with a water inlet section 31a, a threaded section 31b and a water spraying section 31c, the threaded section 31b penetrates the top center of the purification tank body 10 and is threadedly connected with the inner wall of the annular base 21, the rotating blocks 32 are respectively and symmetrically fixedly installed on the two sides of the water inlet section 31a close to the threaded section 31b, by arranging the rotating blocks 32, the adjusting assembly 20 realizes the rotation and the up-and-down movement of the cleaning pipe 31 by rotating the rotating blocks 32, the rotating cylinder 22 is rotationally connected with 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 with the moving groove 22b along with the movement of the cleaning pipe 31, by arranging the moving groove 22b, the rotation of the rotating cylinder 22 is realized, and the movement space of the rotating block 32 and the limiting during the movement are provided, the T-shaped sliding block 22a and the T-shaped sliding groove are further arranged to assist the moving groove 22b to drive the rotating block 32 to rotate and further drive the cleaning pipe 31 to rotate, the center of the limiting cross rod 33 is fixedly connected with the bottom of the cleaning pipe 31, one side of the scraper 34 is respectively and fixedly installed on the two ends of the limiting cross rod 33, the side of the scraper 34 close to the inner wall of the purification tank body 10 is adapted to the inner wall of the purification tank body 10, the scraper 34 closely abuts and scrapes the inner wall of the purification tank body 10, so that the particulate matters, oil stains, scale and other impurities possibly deposited on the tank wall during the waste gas treatment process are effectively removed, the cleaning of the inner wall of the purification tank body 10 is maintained, and the influence of the accumulation of the impurities on the purification effect is avoided, the scraper 34 is provided with a scraping slope, by arranging the scraping slope, the scraping effect of the scraper 34 when scraping the inner wall of the purification tank body 10 is better.

[0028] As Figure 6As shown, the cleaning assembly 30 further comprises a movable ring 35 and a limiting ring 36, the cleaning pipe 31 is provided with a water flow channel, the movable ring 35 is arranged in the water inlet section 31a and is in sliding connection with 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 arranged at a position close to the bottom of the water spraying section 31c, and the limiting ring 36 is fixedly sleeved at a position close to the threaded section 31b of the water spraying section 31c. By arranging the limiting ring 36, the cleaning pipe 31 can be prevented from being separated during the rising process, and the filter assembly 40 can also be limited. The filter assembly 40 comprises a connecting ring 41, a sliding ring 42, 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 in sliding sleeve connection with the outer surface of the water spraying section 31c. One end of each baffle 43 is fixed to the connecting ring 41, and the other end of each baffle 43 is fixed to the sliding ring 42. The baffles 43 correspond to the atomizing nozzles 31d and effectively block the atomizing nozzles 31d to avoid water waste. One end of each connecting plate 44 is fixed to the side adjacent to the baffle 43 of the connecting ring 41, and the other end of each connecting plate 44 is fixedly connected to the large end of the conical filter cloth 45. By arranging the conical filter cloth 45 in a conical shape, the contact area between the conical filter cloth 45 and the toxic gas is effectively increased, which can effectively filter and purify the toxic gas generated during the feed production process, so that the discharged gas meets the requirements. The atomizing nozzles 31d are located in the recessed area of the conical filter cloth 45, which can ensure that the washing water flow directly acts on the surface of the conical filter cloth 45 and the recessed part below, ensuring that each part of the conical filter cloth 45 can be fully washed to prevent local blockage or reduced filtering efficiency due to incomplete washing. The design of the atomizing nozzles 31d makes the water flow spray in a mist form. This atomizing washing method can more evenly cover the surface of the conical filter cloth 45, improving the washing effect. At the same time, the mist water flow can more effectively penetrate into the fiber gap of the conical filter cloth 45 to remove trapped impurities. The adjacent connecting plates 44 form a fan-shaped flow area, which can make the waste gas contact more fully when passing through the conical filter cloth 45, helping the harmful substances in the waste gas to be more effectively adsorbed, thereby improving the purification effect and facilitating better discharge of the filtered waste gas. The small end of the conical filter cloth 45 is provided with a bottom ring 45a in sliding sleeve connection with the water spraying section 31c.

[0029] In use, the dust exhaust gas generated in the feed production process is sent into the inside of the purification tank body 10 through the air inlet pipe 11. In the process of rising, the exhaust gas is filtered through the conical filter cloth 45. The clean gas filtered through the conical filter cloth 45 is discharged from the air outlet pipe 12 at the top end of the purification tank body 10, achieving the purpose of purifying the exhaust gas. When the conical filter cloth 45 has no or a small amount of impurities, the exhaust gas can be filtered through the conical filter cloth 45. The bottom ring 45a at the lower end of the conical filter cloth 45 is in contact with the upper surface of the limiting cross rod 33. At this time, the baffle 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 the impurities are too much, 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, the baffle 43 on the connecting ring 41 and the sliding ring 42 fixedly connected with the baffle 43 to slide upward as a whole, thereby removing the limitation of the baffle 43 on the atomizing nozzle 31d. The water flow cleans the conical filter cloth 45 through the atomizing nozzle 31d. Until the impurities at the filter hole position of the conical filter cloth 45 are cleaned, the gravity of the filtering assembly 40 as a whole is greater than the force of the exhaust gas, so that the filtering assembly 40 as a whole slides downward until the baffle 43 reblocks the atomizing nozzle 31d, and then the exhaust gas is filtered and purified again.

[0030] 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 after a long time. In order to clean the impurities on the conical filter cloth 45 and the inner wall of the purification tank body 10 regularly, the main gear 23 is driven by the motor 25, thereby driving the pinion 24 and the rotating cylinder 22 to rotate. The rotating block 32 is driven to rotate by the moving groove 22b formed in the inner wall of the rotating cylinder 22. The inner thread on the inner wall of the annular base 21 is threadedly connected with the threaded segment 31b on the cleaning pipe 31, so that the cleaning pipe 31 as a whole rotates and moves upward, thereby driving the scraper 34 at the bottom of the cleaning pipe 31 to scrape the inner wall of the purification tank body 10, and driving the conical filter cloth 45 to move up and down, so that the conical filter cloth 45 is cleaned more thoroughly, 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 filtration and purification of the toxic gas.

[0031] The application also provides the liquid inlet pipe 13, which can inject clean water into the inside of the purification tank body 10. The impurities scraped off the purification tank body 10 and the impurities washed off the conical filter cloth 45 can be effectively flushed into the waste liquid treatment section 10b. The waste water generated when the impurities scraped off the purification tank body 10 and the conical filter cloth 45 is cleaned can be effectively discharged through the liquid outlet pipe 14 in time, avoiding the accumulation of waste water, ensuring a clean environment inside the purification tank body 10, and improving the exhaust gas purification effect to a certain extent.

[0032] AsFigure 1 As shown, the cleaning device further comprises a mounting bracket 50, the mounting bracket 50 comprises 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 fixing ring 52 is fixedly installed on one end of the plurality of fixing columns 51 on the side adjacent to the purification tank body 10, so as to facilitate the fixation of the purification tank body 10.

The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the description given above, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
