Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding ventilation, and particularly to a filtering structure for a poultry breeding ventilation device. Background Art

[0002] Poultry breeding includes the breeding of various chickens, ducks, and geese, mainly for providing meat and eggs. During the breeding process, due to the intensive management of poultry and high density, ventilation of the breeding farm is required.

[0003] A filtering structure for a poultry breeding ventilation device with the publication number of CN218392719U in the prior art includes a breeding farm. One end of the inner top of the breeding farm is fixedly connected with a mounting plate. One end of the bottom of the mounting plate is fixedly connected with a telescopic pipe. The bottom of the telescopic pipe is fixedly connected with an air inlet pipe. A first filter layer is clamped inside the air inlet pipe. One end of the top of the mounting plate is provided with an air delivery pipe. A second filter layer is clamped inside the air delivery pipe. Compared with the prior art, the first filter layer is used to filter dust and fluff in the air, ozone is input into the second filter layer. The second filter layer is made of sponge material, which is convenient for the full mixing of ozone and waste gas, achieving the effect of filtering and deodorizing, so that the discharged air will not pollute the environment and meets the emission standards. By lowering the telescopic pipe, it is convenient to disassemble, assemble and clean the first filter layer at the bottom of the telescopic pipe.

[0004] For the above filtering structure, it needs to be disassembled later for cleaning, which increases the workload of the staff. When the breeding area, such as duck down and goose down, blocks the filtering structure, it needs to be manually cleaned regularly. If the cleaning is not timely, it will lead to a reduction in the subsequent filtering effect and also reduce the air exchange effect in the breeding area. Therefore, this application proposes a filtering structure for a poultry breeding ventilation device. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Automatic cleaning and continuous efficient filtration: The motor drives the dust filter screen to rotate cyclically and soak in clean water, combined with the negative pressure adsorption of impurities by the reciprocating suction pipe, realizing the dynamic cleaning of the dust filter screen and avoiding local blockage.

After the waste gas is mixed with ozone, it passes through the wet dust filter screen to adsorb dust and feathers (such as duck down and goose down), forming a dual treatment of "chemical purification + physical filtration". The discharged gas has high cleanliness, reducing environmental pollution, and no additional purification equipment needs to be installed, saving costs.

The user only needs to open the box door to quickly take out the filter screen for cleaning, solving the cumbersome problem of frequent disassembly in the traditional structure and greatly improving the maintenance convenience.

[0019] In summary, the present invention combines the movable dust filter screen with clean water to improve the dust suction ability, effectively filter the dust and floating objects in the air, avoid local blockage, and ensure the filtering effect; at the same time, through the design of the air supply mechanism and the suction pipe, the impurities on the dust filter screen are automatically cleaned, eliminating the need for manual disassembly and cleaning, reducing the labor intensity, and ensuring the continuous and efficient operation of the filtering structure.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1 - 5 , a filtering structure for a poultry farming ventilation device, including a support 1, and the support 1 is installed on the house or shed for poultry farming; a filter box 2 and a collection box 4 are installed on the support 1, an intake pipe 10 is installed on the filter box 2, and an ozone generator 34 is installed on the intake pipe 10. The ozone generator 34 emits ozone, and the waste gas and ozone are fully mixed to achieve the purpose of purification. A ventilation fan group 35 is installed at the bottom of the intake pipe 10, which can transport the air in the breeding area to the filter box 2 through the intake pipe 10.

[0024] An exhaust pipe 36 is installed at the upper end of the filter box 2, which can discharge the treated gas out of the breeding area; two shaft rods 25 distributed up and down are rotatably connected inside the filter box 2, drive rollers 23 are fixed on both of the two shaft rods 25, a mesh conveyor belt 24 is sleeved on the two drive rollers 23, and a dust filter net is fixed on the outside of the mesh conveyor belt 24; since there is clear water inside the filter box 2 and the lower drive roller 23 is located in the clear water, the dust filter net will enter the clear water, and the clear water can wet the dust filter net, increasing the dust suction capacity of the dust filter net and filtering dust better.

[0025] A motor 3 for driving the shaft rod 25 to rotate is installed on the filter box 2, a gas storage tank 5 is installed on the collection box 4, the gas storage tank 5 is connected to the collection box 4 through a delivery pipe 6, a pressure relief valve 7 is installed on the delivery pipe 6, and a hose 8 is installed on the delivery pipe 6, and the hose 8 penetrates through the filter box 2.

[0026] It further includes a gas supply mechanism for supplying gas into the gas storage tank 5. The gas supply mechanism includes a mounting block 32 fixed on the filter tank 2. A piston cylinder 12 is mounted on the mounting block 32. A moving piston 33 is slidably connected inside the piston cylinder 12. A connecting shaft 27 is fixed on the lower side shaft rod 25. A circular plate 19 is fixed on the connecting shaft 27. A connecting rod 26 is eccentrically hinged to the circular plate 19. The connecting rod 26 is hinged to the moving piston 33. When the circular plate 19 rotates, driven by the connecting rod 26, the moving piston 33 reciprocates up and down inside the piston cylinder 12.

[0027] An air outlet pipe 11 and an air suction pipe 13 are mounted on the piston cylinder 12. The air outlet pipe 11 is connected to the gas storage tank 5. An air outlet check valve 14 is mounted on the air outlet pipe 11. The air outlet check valve 14 only allows air to flow from the piston cylinder 12 into the air outlet pipe 11. An air inlet check valve 15 is mounted on the air suction pipe 13. The air inlet check valve 15 only allows air to enter the piston cylinder 12 through the air suction pipe 13.

[0028] A moving block 30 reciprocates inside the filter tank 2. A dust suction pipe 31 opposite to the dust filter net is mounted at the bottom of the moving block 30. The flexible hose 8 is connected to the dust suction pipe 31. A reciprocating lead screw 28 is rotatably connected inside the filter tank 2. The reciprocating lead screw 28 passes through the moving block 30 and is in mating connection with it. A guide rod 29 is fixedly connected inside the filter tank 2. The guide rod 29 passes through the moving block 30 and is slidably connected with it. When the reciprocating lead screw 28 rotates, the guided moving block 30 reciprocates, thereby driving the dust suction pipe 31 to reciprocate.

[0029] It further includes a transmission mechanism. The transmission mechanism includes two short shafts 18. One of the short shafts 18 is fixedly connected to the shaft rod 25, and the other short shaft 18 is fixedly connected to the reciprocating lead screw 28. Synchronous wheels 16 are mounted on both short shafts 18. The two synchronous wheels 16 are connected by a synchronous belt 17. When the shaft rod 25 is driven to rotate by the motor 3, it will drive the short shaft 18 to rotate. Driven by the synchronous wheels 16 and the synchronous belt 17, the reciprocating lead screw 28 rotates.

[0030] For further explanation of the collection box 4: A box door is mounted on the collection box 4. A mesh exhaust window 9 is mounted on the box door. A magnetic rectangular frame 20 is fixed on the inner wall of the collection box 4. A magnetic frame 21 is adsorbed on the magnetic rectangular frame 20. The magnetic frame 21 is slidably abutted against the inner wall of the collection box 4, and a filter net 22 is mounted inside the magnetic frame 21. Among them, as Figure 4 shown, the conveying pipe 6 is located on the right side of the magnetic frame 21. [[ID=ID=16]]

[0031] When the present invention is in use, the ozone generator 34 and the ventilation fan group 35 work. Air enters the air inlet pipe 10. The ozone generator 34 works to generate ozone. During the process of conveying air, air can be mixed. The waste gas and ozone are fully mixed, and the waste gas can be purified. The purified waste gas enters the filter tank 2.

[0032] The motor 3 operates to drive the shaft rod 25 to rotate. With the cooperation of the transmission roller 23 and the mesh conveyor belt 24, the dust filter net rotates. The purified waste gas blows towards the movable and wet dust filter net, and dust, floating objects such as duck down and goose down can be adsorbed through the dust filter net, thus realizing the filtration of air. The filtered air is discharged outside the breeding area through the exhaust pipe 36. In this way, the discharged purified and filtered air will not affect the external environment.

[0033] Since the dust filter net is in a movable state, it will not cause local blockage of the dust filter net, so that the waste gas can be better filtered.

[0034] The rotation of the shaft rod 25 drives the rotation of the connecting shaft 27. The rotation of the connecting shaft 27 drives the rotation of the circular plate 19. The rotation of the circular plate 19 drives the movement of the connecting rod 26. In this way, the moving piston 33 guided by the piston cylinder 12 can move up and down. When the moving piston 33 moves downward, the inside of the piston cylinder 12 is in a negative pressure state, and the intake one-way valve 15 opens, and air enters the piston cylinder 12 through the suction pipe 13. When the moving piston 33 moves upward, the inside of the piston cylinder 12 is in an overpressure state, and the outlet one-way valve 14 opens, and the air can be transported to the air storage tank 5 through the outlet pipe 11.

[0035] In this way, the circular plate 19 continuously rotates, and can intermittently transport air into the air storage tank 5. When the pressure at the pressure relief valve 7 is greater than the threshold value of the pressure relief valve 7, the pressure relief valve 7 opens, and the high-pressure and high-speed air is discharged through the delivery pipe 6 and blows into the collection box 4; when the high-speed air passes through the hose 8, the air flow velocity at the port of the hose 8 is large and the pressure is small, while the air flow velocity at the port of the dust suction pipe 31 connected to the hose 8 is low and the pressure is large, and a negative pressure is formed at the port of the dust suction pipe 31. In this way, the impurities filtered on the dust filter net can be sucked away and transported into the delivery pipe 6 through the hose 8, and finally transported into the collection box 4.

[0036] The rotation of the shaft rod 25 drives the rotation of the synchronous pulley 16. Under the transmission of the synchronous belt 17, the synchronous pulley 16 and the reciprocating lead screw 28 rotate. The rotation of the reciprocating lead screw 28 makes the guided moving block 30 reciprocate, and then drives the dust suction pipe 31 to reciprocate. The movement of the dust suction pipe 31 can suck away the impurities filtered on the movable dust filter net, realizing the cleaning of the dust filter net. There is no need for manual cleaning, which can effectively treat the waste gas in the breeding area and is also beneficial to the ventilation and air exchange in the breeding area.

[0037] The air and the filtered impurities are transported into the collection box 4. The air is filtered through the filter net 22 to realize the collection of the cleaned impurities, and finally the air is discharged through the mesh exhaust window.

[0038] When it is necessary to clean the impurities inside the collection box 4, open the box door, and pull the magnetic frame 21 by hand to separate it from the magnetic rectangular frame 20, so that the filter screen 22 can be removed to clean the impurities on the collection box 4 and the filter screen 22.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
