Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically a self-cleaning biological deodorization tower. Background Technology

[0002] Biological deodorization towers are devices that utilize microorganisms for deodorization. Pollutants in the exhaust gas come into contact with water, dissolving into molecules or ions in the liquid phase. The malodorous components in the exhaust gas solution are then decomposed by the microorganisms, transferring from the water into the microorganisms. The organic matter within the microbial cells is oxidized and decomposed by various enzymes, thus achieving the goal of odor control. Pig farm exhaust typically contains ammonia, hydrogen sulfide, and other malodorous gases, which are the main sources of odor in pig farms. Livestock farms generally use biological deodorization towers to deodorize the air inside the farm, significantly improving the air quality around the pig farm.

[0003] Chinese patent CN217568012U discloses a biological deodorization tower, comprising a tower body with a water tank at the bottom. The tower body contains a humidification zone, a biological deodorization zone, and an adsorption deodorization zone. The water tank is connected to the main water outlet pipe at the top of the humidification zone and the biological deodorization zone via a lifting water pipe. The main water outlet pipe has several branch pipes, each with several vertical pipes connected to nozzles at their bottoms. The main water outlet pipe is connected to an external structure via several sets of connecting rods and fixing clamps, and is located within the fixing clamps. The tower body is divided into interconnected humidification, biological deodorization, and adsorption deodorization zones by a first partition connected to the top of the water tank and a second partition connected to the top of the tower body. The humidification zone has an air inlet pipe on its side. The biological deodorization zone has several layers of biological packing material arranged from top to bottom. The adsorption deodorization zone has several layers of activated carbon arranged from top to bottom. The adsorption deodorization zone has an outlet at the top. The lifting water pipe has a pump body and is connected to the main water outlet pipe via a bend.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent does not allow for the periodic repositioning of the packing material, enabling microorganisms on the packing material to uniformly treat the malodorous components in the solution, nor does it allow for continuous cleaning of sludge deposits on the inner wall of the cylinder.

[0006] Therefore, those skilled in the art have provided a self-cleaning biological deodorization tower to solve the above problems. Utility Model Content

[0010] Furthermore, the displacement drive assembly includes: a servo motor, a worm gear, a worm wheel, and a retainer. The servo motor is fixedly mounted on both ends of the cylinder via a motor bracket. The worm gear is fixedly mounted on the output shaft of the servo motor. A worm wheel is fixedly mounted on one end of the inner shaft and the other end of the outer shaft. The worm wheel and the worm gear mesh with each other. The two retainers are fixedly mounted on the left and right sides of the cylinder, respectively.

[0011] Furthermore, the cleaning device includes: an arc-shaped plate, a connecting plate, and a scraper. Two arc-shaped plates are disposed on the lower side of the cylinder, two connecting plates are fixedly installed between the two arc-shaped plates, and multiple scrapers are fixedly installed on the arc-shaped plates.

[0012] Furthermore, the cleaning device also includes: left and right moving components, with two left and right moving components respectively installed on the front and rear sides inside the cylinder;

[0013] Furthermore, the left and right moving component includes: a rack, a vertical plate, gears, and a stepper motor. The rack is fixedly installed on the inner wall of the cylinder, the vertical plate is fixedly installed on the upper side of the connecting plate, the two gears are rotatably connected to the vertical plate through a rotating shaft, the gears and the rack mesh with each other, the stepper motor is fixedly installed on the vertical plate, and the output shaft of the stepper motor is fixedly connected to the rotating shaft of one of the gears.

[0014] Furthermore, the left and right moving component also includes: an auxiliary sewage discharge component, which is installed on the cylinder body and includes: a sewage discharge port and an observation window. The sewage discharge port is fixedly installed on the lower right side of the cylinder body, and the observation window is fixedly installed on the right side wall of the cylinder body.

[0015] Furthermore, the circulation device includes: hollow tubes, nozzles and a water pump.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses the servo motor output shaft of the displacement drive component to rotate the worm gear, which in turn rotates the worm wheel. The worm wheel rotates the rear rotating frame 180 degrees and stops rotating. The worm wheel rotates the front rotating frame 90 degrees and stops rotating. At this time, the packing material on the lower side of the front rotating frame is transferred to the upper side. The worm wheel rotates the rear rotating frame and then rotates it 90 degrees and stops rotating. At this time, the packing material on the lower side of the rear rotating frame is transferred to the upper side. This allows the packing material on the upper and lower sides of the rotating frame to be alternately displaced, which is beneficial for the microorganisms on the packing material to uniformly treat the malodorous components in the solution.

[0018] 2. By synchronously rotating the two rotating frames 180 degrees, they are positioned on the upper side of the cylinder. The stepper motor output shaft of the left-right moving component of the cleaning device rotates, driving the gear to rotate. The gear rotates, causing it to move left and right on the rack. This movement of the gear on the rack drives the vertical plate to move left and right, which in turn drives the connecting plate to move left and right. This movement of the connecting plate then drives multiple scrapers on the arc-shaped plate to move left and right. The scrapers scrape off sludge and other deposits from the inner wall of the cylinder. The sludge and other deposits fall into the solution at the bottom of the cylinder. The drain port is then opened to discharge the waste liquid from the cylinder, facilitating continuous left-right cleaning of sludge and other deposits from the inner wall of the cylinder.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9A self-cleaning biological deodorization tower includes a base plate 1, and further includes: a deodorization device 2, a cleaning device 3, and a circulation device 4. The deodorization device 2 is installed on the upper side of the base plate 1, the cleaning device 3 is installed inside the deodorization device 2, and the circulation device 4 is installed on the left side of the base plate 1. The deodorization device 2 includes: a cylinder 21, an outer shaft 22, an inner shaft 23, a rotating frame 24, and a baffle 25. The cylinder 21 is fixedly installed on the upper side of the base plate 1. An air inlet 26 is fixedly installed on the upper left side of the cylinder 21, and an air outlet 27 is fixedly installed on the upper right side of the cylinder 21. The two outer shafts 22 are rotatably and sealingly connected to the left and right sides of the cylinder 21, and the inner shaft 23 is rotatably and sealingly connected to the outer shaft 25. On the middle side of shaft 22, both the outer shaft 22 and the inner shaft 23 are coaxial with the cylinder 21. Two rotating frames 24 are arranged on the front and rear sides of the lower part of the cylinder 21. The front rotating frame 24 is fixedly installed on the inner shaft 23, and the rear rotating frame 24 is fixedly installed on the outer shaft 22. Each rotating frame 24 is hinged to a baffle 25 at one end near the center of the cylinder 21. The lower side of the baffle 25 is fixedly connected to the rotating frame 24 by fixing screws. Multiple openings are provided on the rotating frame 24 and the baffle 25. Multiple fillers are placed inside the rotating frame 24. The deodorization device 2 also includes a displacement drive assembly. Two displacement drive assemblies are installed on the left and right sides of the cylinder 21.

[0032] The deodorization device 2 deodorizes the gas, the cleaning device 3 cleans the sludge and other impurities from the inner wall of the equipment, and the circulation device 4 circulates and sprays the solution inside the equipment to improve the adsorption effect on the gas.

[0033] like Figure 6 , Figure 8 , Figure 9 As shown, rotate the rotating frame 24 of the deodorizing device 2 to a suitable position, unscrew the screws on the lower side of the baffle 25, open the baffle 25, and place a suitable number of packing materials inside the rotating frame 24. The packing materials can be set as multi-faceted hollow sphere packing materials, and suitable microorganisms are pre-cultured on the packing materials. After the packing materials are placed, close the baffle 25, tighten the screws on the lower side of the baffle 25, place a suitable amount of solution inside the cylinder 21, and let the gas to be treated enter through the air inlet 26 of the deodorizing device 2. The malodorous components in the gas to be treated are absorbed by the solution, and the microorganisms decompose the malodorous components in the solution to achieve the purpose of deodorization.

[0034] The displacement drive assembly includes a servo motor 28, a worm gear 29, a worm wheel 210, and a retainer 211. The servo motor 28 is fixedly mounted on both ends of the cylinder 21 via motor brackets. The worm gear 29 is fixedly mounted on the output shaft of the servo motor 28. The worm wheel 210 is fixedly mounted on one end of the inner shaft 23 and the other end of the outer shaft 22. The worm wheel 210 and the worm gear 29 mesh with each other. The two retainers 211 are fixedly mounted on the left and right sides of the cylinder 21.

[0035] like Figure 1 , Figure 6 As shown, the servo motor 28 of the displacement drive assembly rotates, driving the worm gear 29 to rotate. The worm gear 29 rotates, driving the worm wheel 210 to rotate. The worm wheel 210 rotates, driving the rear rotating frame 24 to rotate 180 degrees and then stop rotating. The worm wheel 210 rotates, driving the front rotating frame 24 to rotate 90 degrees and then stop rotating. At this time, the packing material on the lower side of the front rotating frame 24 is transferred to the upper side. The worm wheel 210 rotates, driving the rear rotating frame 24 to rotate 90 degrees and then stop rotating. At this time, the packing material on the lower side of the rear rotating frame 24 is transferred to the upper side, so that the packing material on the upper and lower sides of the rotating frame 24 can be alternately displaced, allowing the microorganisms on the packing material to uniformly treat the malodorous components in the solution.

[0036] Example 2: In some embodiments, such as Figures 1-9 In a preferred embodiment of the present invention, the cleaning device 3 includes: an arc-shaped plate 31, a connecting plate 32, and a scraper 33. Two arc-shaped plates 31 are disposed on the lower side of the cylinder 21, two connecting plates 32 are fixedly installed between the two arc-shaped plates 31, and a plurality of scrapers 33 are fixedly installed on the arc-shaped plates 31.

[0037] The cleaning device 3 further includes: left and right moving components, two of which are respectively installed on the front and rear sides inside the cylinder 21.

[0038] like Figure 7 As shown, the left and right moving assembly includes: a rack 34, a vertical plate 35, a gear 36, and a stepper motor 37. The rack 34 is fixedly installed on the inner wall of the cylinder 21, the vertical plate 35 is fixedly installed on the upper side of the connecting plate 32, the two gears 36 are rotatably connected to the vertical plate 35 through a rotating shaft, the gears 36 and the rack 34 mesh with each other, the stepper motor 37 is fixedly installed on the vertical plate 35, and the output shaft of the stepper motor 37 is fixedly connected to the rotating shaft of one of the gears 36.

[0039] The two rotating frames 24 are rotated 180 degrees synchronously, so that the two rotating frames 24 are rotated to the upper side of the cylinder 21. The output shaft of the stepper motor 37 of the left and right moving component of the cleaning device 3 rotates, which drives the gear 36 to rotate. The rotation of the gear 36 causes the gear 36 to move left and right on the rack 34. The left and right movement of the gear 36 on the rack 34 drives the vertical plate 35 to move left and right. The left and right movement of the vertical plate 35 drives the connecting plate 32 to move left and right. The left and right movement of the connecting plate 32 drives the multiple scrapers 33 on the arc plate 31 to move left and right. The left and right movement of the multiple scrapers 33 scrapes off the sludge and other attachments on the inner wall of the cylinder 21. The sludge and other attachments fall into the solution on the lower side of the cylinder 21.

[0040] The left and right moving component also includes an auxiliary sewage discharge component, which is installed on the cylinder 21. The auxiliary sewage discharge component includes a sewage discharge port 38 and an observation window 39. The sewage discharge port 38 is fixedly installed on the lower right side of the cylinder 21, and the observation window 39 is fixedly installed on the right side wall of the cylinder 21.

[0041] like Figure 2 , Figure 4 , Figure 6 As shown, sludge and other attached substances fall into the solution on the lower side of the cylinder 21. The drain port 38 can be opened to discharge the waste liquid from the cylinder 21, and the cleaning status inside the cylinder 21 can be observed through the observation window 39.

[0042] The circulation device 4 includes: hollow tubes 41, nozzles 42 and water pump 43. Multiple hollow tubes 41 are fixedly installed on the upper side of the cylinder 21. Multiple nozzles 42 are fixedly installed on each hollow tube 41. The water pump 43 is fixedly installed on the left side of the base plate 1. One end of each of the multiple hollow tubes 41 is fixedly connected to the output end of the water pump 43.

[0043] like Figure 1 , Figure 4 , Figure 6 As shown, the circulation device 4 further includes: a buffer tank 44, a connecting pipe 45, and a filter screen 46. The buffer tank 44 is fixedly installed on the left side of the base plate 1. One end of the connecting pipe 45 is fixedly connected to the left side of the cylinder 21, and the other end of the connecting pipe 45 is fixedly connected to the right side of the buffer tank 44. The input end of the water pump 43 is fixedly connected to the left side of the buffer tank 44, and multiple filter screens 46 are fixedly installed inside the buffer tank 44 on the right side.

[0044] The solution inside the cylinder 21 flows into the buffer tank 44 of the circulation device 4 through the connecting pipe 45 on the left side of the cylinder 21. After being filtered by the filter screen 46, the solution enters the left side of the buffer tank 44. The water pump 43 pumps the filtered solution from the lower left side of the buffer tank 44 into multiple hollow tubes 41. The filtered solution is sprayed out from the nozzles 42 of the hollow tubes 41 to spray the space on the upper side of the cylinder 21, so that the gas to be treated is continuously sprayed when it passes through the upper side of the cylinder 21, which helps to improve the deodorization effect of the gas to be treated.

[0045] Furthermore, the stepper motor 37 is positioned above the solution inside the cylinder 21, and the liquid level inside the cylinder 21 is level with the top of the rotating frame 24. The solution is only used to soak the filler inside the rotating frame 24. Since the stepper motor 37 is higher than the top of the rotating frame 24, the stepper motor 37 will not be immersed in the solution. Of course, a waterproof stepper motor available on the market can be used for the stepper motor 37 to avoid malfunctions caused by water ingress during use.

[0046] like Figure 6As shown, there is a certain space between the rotating frame 24 and the inner wall of the cylinder 21, and the stepper motor 37 is installed in this space. Therefore, there is a gap between the rotating frame 24 and the stepper motor 37, so as to avoid interference between the rotating frame 24 and the stepper motor 37 when the rotating frame 24 rotates.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
