Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment in breeding farms, and particularly to a wastewater treatment device for beef cattle breeding farms. Background Art

[0002] A wastewater treatment device for beef cattle breeding farms refers to a series of equipment and systems specifically used to treat the wastewater generated by beef cattle breeding farms. These wastewaters usually contain high concentrations of organic matter, suspended solids, ammonia nitrogen, pathogens and other pollutants. If directly discharged without treatment, they will cause serious pollution to the environment. Therefore, it is particularly important to use an appropriate wastewater treatment device to treat the wastewater of beef cattle breeding farms.

[0003] For example, the publication number is CN117886458A. This invention relates to the technical field of sewage treatment, specifically to a wastewater treatment device for beef cattle breeding farms, including an aeration tank for treating wastewater. The bottom surface inside the aeration tank is paved with an air distribution pipeline, and several aeration components are arranged on the air distribution pipeline. An air adding component for supplying air to the air distribution pipeline is arranged outside the aeration tank; the aeration component includes an air connection pipe threadedly connected to the air distribution pipeline. A ventilation pipe is circumferentially swingably arranged at the top of the air connection pipe, and a jet hood is fixedly installed at one end of the ventilation pipe away from the air connection pipe. By setting the aeration component and the air control component, the effect of improving the coverage area of the air jet holes by the circumferential swing of the jet hood is achieved, ensuring that oxygen is fully mixed into the wastewater, so that one jet hood can replace multiple existing aeration nozzles. At the same time, the size of the air jet holes can be changed to ensure that oxygen is fully mixed into the wastewater. By using the change of the air pressure inside the jet hood, it is possible to avoid the blockage of the air jet holes by suspended solids and particles.

[0004] In the above-mentioned prior art, wastewater is added to the treatment tank, and the air pump is started. The air pump transports oxygen into the air adding component, and then it is sprayed out through multiple aeration nozzles. During the jetting process, the jetting nozzles perform multi-directional movement with the force generated by the jetting, ensuring full mixing of oxygen. However, there are pollution particles in the wastewater, and the fine pollution particles will fill the gaps at the aeration nozzles, thus affecting the deflection of the aeration nozzles. Moreover, the gas sprayed out by the aeration nozzles will quickly rise in the wastewater, a large amount of oxygen cannot be absorbed, and the too-fast rising speed of oxygen will wash away the microorganisms. Therefore, it will affect the oxygen absorption of the microorganisms and the activity of the microorganisms. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art that there are pollution particles in the wastewater, the fine pollution particles will fill the gaps at the aeration nozzles, thus affecting the deflection of the aeration nozzles, and the gas sprayed out by the aeration nozzles will quickly rise in the wastewater, a large amount of oxygen cannot be absorbed, and the too-fast rising speed of oxygen will wash away the microorganisms.

At this time, the movement of the moving frame can drive the leveling scraper to scrape the garbage on the treatment tank and discharge it from the other side of the water inlet pipe, so as to facilitate cleaning.

[0019] 3. In the present invention, when the motor is started, the motor drives the rotating shaft to rotate, the rotating shaft drives the irregular gear to rotate, the irregular gear drives a rack to move, the rack drives the sliding plate to move, and the rack also drives the first gear to deflect. The first gear drives the deflecting air pipe to deflect, and the deflecting air pipe drives the atomizing nozzle to deflect, thereby spraying oxygen in multiple directions. Therefore, it can avoid the obstruction of the deflection of the atomizing nozzle caused by a large amount of accumulated sediment. After the engagement between the irregular gear and one rack ends, it engages with another rack. Therefore, the two racks move reciprocally and alternately, enabling the atomizing nozzle to deflect continuously. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 8 , the present invention provides a technical solution: a wastewater treatment device for beef cattle farms, including a treatment tank 1, a plurality of filter plates 11 are fixedly connected inside the treatment tank 1, fixed baffles 12 are fixedly connected on both sides of the filter plates 11, an air adding component is arranged at the bottom end of the treatment tank 1, an oxygen rising buffer structure is arranged at the top end of the treatment tank 1, the oxygen rising buffer structure includes an oxygen blocking component and a spreading and discharging component, the oxygen blocking component includes a moving frame 31, the moving frame 31 is slidably connected inside the treatment tank 1, and the middle part of the moving frame 31 is hollow and is slidably connected on both sides of the filter plate 11.

[0032] Such as Figure 1 - Figure 8As shown, on one side of the top end of the moving frame 31, a first screw rod 311 is threadedly connected. On the other side of the top end of the moving frame 31, a limiting rod 3111 is slidably connected. At both ends of the first screw rod 311 and the limiting rod 3111, support blocks 312 are provided, and the support blocks 312 are fixed to the top end of the treatment tank 1. At equal intervals at the bottom end of the moving frame 31, dispersion scraping teeth 317 are arranged, and the dispersion scraping teeth 317 are slidably connected to the bottom end inside the treatment tank 1. One end of the first screw rod 311 is fixedly connected to a second runner 313, and a belt 314 is drivingly connected to the middle of the second runner 313. A plurality of moving baffles 315 are slidably connected to the middle of the moving frame 31. The moving baffles 315 are arranged at intervals, and both ends of the moving baffles 315 are slidably connected to both sides inside the treatment tank 1. The moving baffles 315 are slidably connected to the bottom end of the filter plate 11, and fixed dispersion blades 316 are fixedly connected at equal intervals at the bottom end of the moving baffles 315.

[0033] In this embodiment, in the present invention, the staff starts the motor 211 to drive the first runner 212 to rotate. The first runner 212 drives the first screw rod 311 to rotate through the belt 314. The first screw rod 311 drives the moving frame 31 to slowly reciprocate inside the treatment tank 1. The moving frame 31 drives the moving baffle 315 and the dispersion scraping teeth 317 to move. The moving baffle 315 drives the fixed dispersion blade 316 to move. The moving baffle 315 and the filter plate 11 cooperate to block the bubbles, increasing the residence time of the bubbles in the treatment tank 1, reducing the bubble flow rate, increasing the dissolved oxygen concentration in the wastewater, enabling the microorganisms to have enough time to absorb more oxygen, thus accelerating the metabolic activities of the microorganisms, thereby improving the treatment efficiency. Moreover, the reciprocating movement of the moving baffle 315 and the fixed dispersion blade 316 can stir the wastewater and the bubbles, enabling the microorganisms to be evenly distributed and fully absorb oxygen to decompose the wastewater. Among them, when the moving baffle 315 moves to one end, it will be in pressing contact with the treatment tank 1, and after the moving baffle 315 is subjected to pressure, it will slide to the other side of the moving frame 31, thereby further blocking the bubbles.

[0034] As Figure 1 - Figure 8As shown in the figure, the flattening and discharging component includes a fixing frame 32, which is fixed to the top end of the moving frame 31. The middle part of the bottom end of the fixing frame 32 is rotatably connected to a second screw rod 321. The top end of the second screw rod 321 penetrates through the fixing frame 32. The bottom end of the second screw rod 321 is threadedly connected to a leveling scraper 322. The leveling scraper 322 slidably penetrates through the moving frame 31. The bottom end of the leveling scraper 322 is slidably connected to the top end of the filter plate 11. One end of the second screw rod 321 located inside the fixing frame 32 is fixedly connected to a second gear 323. A third gear 324 is meshed with one side of the second gear 323. One side of the third gear 324 away from the second gear 323 is fixedly connected to a rotating rod 325. The rotating rod 325 penetrates through the fixing frame 32 and is rotatably connected to the fixing frame 32. One end of the rotating rod 325 located outside the fixing frame 32 is fixedly connected to a turntable 326.

[0035] In this embodiment, the topmost filter plate 11 filters the incoming wastewater. After stopping adding wastewater, the moving frame 31 is moved to one side of the water inlet pipe and the turntable 326 is rotated. The turntable 326 drives the rotating rod 325 to rotate. The rotating rod 325 drives the third gear 324 to rotate. The third gear 324 drives the second gear 323 to rotate. The second gear 323 drives the second screw rod 321 to rotate. The rotation of the second screw rod 321 drives the leveling scraper 322 to move downward. The leveling scraper 322 gradually approaches the filter plate 11 and stops after descending to a certain distance above the filter plate 11. At this time, the moving frame 31 drives the fixing frame 32 to move, and the fixing frame 32 drives the leveling scraper 322 to flatten the garbage filtered on the treatment tank 1. The flattened garbage can cover the top end of the filter plate 11, thereby blocking the discharged oxygen and reducing the oxygen discharge speed, which helps the absorption of oxygen. After the wastewater treatment is completed and the moving frame 31 is located on one side of the water inlet pipe, the turntable 326 is continuously rotated to make the leveling scraper 322 contact the filter plate 11. At this time, the movement of the moving frame 31 can drive the leveling scraper 322 to scrape the garbage on the treatment tank 1 and discharge it from the other side of the water inlet pipe, so as to facilitate cleaning.

[0036] As Figure 1 - Figure 8As shown in the figure, the gas injection component includes an air pump 21. One side of the air pump 21 is fixedly connected to an air inlet pipe 22. The end of the air inlet pipe 22 far from the air pump 21 is fixedly connected to a diverging pipe 23. The diverging pipe 23 is located on one side of the treatment tank 1. Rotatingly connected to the side of the diverging pipe 23 close to the treatment tank 1 at equal intervals are deflecting air pipes 24. The deflecting air pipes 24 penetrate through the bottom end of the treatment tank 1 and are rotatably connected to the treatment tank 1. At the top of the deflecting air pipes 24, atomizing nozzles 25 are fixedly connected at equal intervals. The end of the deflecting air pipe 24 close to the diverging pipe 23 and located outside the treatment tank 1 is fixedly connected to a first gear 26. At the top and bottom of the first gear 26, there are racks 27 engaged therewith. On the side of the rack 27 far from the first gear 26, there is a sliding plate 28 fixedly connected. On the side of the sliding plate 28 close to the treatment tank 1, there is a limiting block 281 fixedly connected. The limiting block 281 is slidably connected to the treatment tank 1. At the end of the rack 27 far from the first gear 26, there is an irregular gear 29 engaged therewith. In the middle of the irregular gear 29, there is a rotating shaft 210 fixedly connected. In the middle of the rotating shaft 210, there is a first runner 212 fixedly connected. The first runner 212 is in transmission connection with a belt 314. At the end of the rotating shaft 210 far from the irregular gear 29, there is a motor 211 in transmission connection.

[0037] In this embodiment, the air pump 21 generates negative pressure to convey it into the deflecting air pipes 24, and finally sprays out fine bubbles through the atomizing nozzles 25. Start the motor 211. The motor 211 drives the rotating shaft 210 to rotate. The rotating shaft 210 drives the irregular gear 29 to rotate. The irregular gear 29 drives one rack 27 to move. One rack 27 drives the sliding plate 28 to move, and one rack 27 drives the first gear 26 to deflect. The first gear 26 drives the deflecting air pipe 24 to deflect. The deflecting air pipe 24 drives the atomizing nozzle 25 to deflect, so as to spray oxygen in multiple directions. Therefore, it can avoid the obstruction of the deflection of the atomizing nozzle 25 caused by too much accumulated sediment. After the irregular gear 29 finishes meshing with one rack 27, it meshes with the other rack 27. Therefore, the two racks 27 reciprocate alternately, making the atomizing nozzle 25 deflect continuously.

[0038] Working principle: First, add wastewater into the interior of treatment tank 1 through the water inlet pipe. The top filter plate 11 filters the incoming wastewater. After stopping adding wastewater, start the motor 211 and the air pump 21. The air pump 21 generates negative pressure and transports it into the deflection air pipe 24, and finally sprays fine bubbles through the atomizing nozzle 25. The motor 211 starts to drive the rotating shaft 210 to rotate. The rotating shaft 210 drives the first runner 212 and the irregular gear 29 to rotate. The irregular gear 29 drives a rack 27 to move. A rack 27 drives the slide plate 28 to move, and a rack 27 drives the first gear 26 to deflect. The first gear 26 drives the deflection air pipe 24 to deflect. The deflection air pipe 24 drives the atomizing nozzle 25 to deflect, so as to spray oxygen in all directions. Therefore, it can avoid the blockage of the deflection of the atomizing nozzle 25 caused by too much accumulated sediment. After the engagement between the irregular gear 29 and a rack 27 ends, it engages with another rack 27. Therefore, the two racks 27 reciprocate alternately, enabling the atomizing nozzle 25 to deflect continuously. The first runner 212 drives the first lead screw 311 to rotate through the belt 314. The first lead screw 311 drives the moving frame 31 to move slowly back and forth inside the treatment tank 1. When the moving frame 31 moves to one side of the water inlet pipe, it stops. Rotate the turntable 326. The turntable 326 drives the rotating rod 325 to rotate. The rotating rod 325 drives the third gear 324 to rotate. The third gear 324 drives the second gear 323 to rotate. The second gear 323 drives the second lead screw 321 to rotate. The rotation of the second lead screw 321 drives the leveling scraper 322 to move downward. The leveling scraper 322 gradually approaches the filter plate 11. When it descends to a certain distance above the filter plate 11, it stops. Then the moving frame 31 continues to move. At this time, the moving frame 31 drives the fixed frame 32, the moving baffle 315 to move, and the dispersing scraping teeth 317 to move. The fixed frame 32 drives the leveling scraper 322 to level the garbage filtered on the treatment tank 1. The leveled garbage can cover the top of the filter plate 11, thereby blocking the discharged oxygen and reducing the oxygen discharge speed, which helps the absorption of oxygen. The moving baffle 315 drives the fixed dispersing leaf 316 to move. The moving baffle 315 and the filter plate 11 cooperate to block the bubbles, increase the residence time of the bubbles in the treatment tank 1, reduce the bubble flow speed, and increase the dissolved oxygen concentration in the wastewater, enabling microorganisms to have enough time to absorb more oxygen. Therefore, it accelerates the metabolic activities of microorganisms, thereby improving the treatment efficiency. Among them, when the moving baffle 315 moves to one end, it will be in extrusion contact with the treatment tank 1. After the moving baffle 315 is subjected to pressure, it slides to the other side of the moving frame 31, further blocking the bubbles. And the reciprocating movement of the moving baffle 315 and the fixed dispersing leaf 316 can stir the wastewater and the bubbles, enabling the microorganisms to be evenly distributed and fully absorb oxygen to decompose the wastewater. When the wastewater treatment is completed and the moving frame 31 is located on one side of the water inlet pipe, continue to rotate the turntable 326 so that the leveling scraper 322 contacts the filter plate 11.At this time, the movement of the moving frame 31 can drive the leveling scraper 322 to scrape the garbage on the treatment tank 1 and discharge it from the other side of the water inlet pipe, so as to facilitate cleaning.

[0039] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
