Description

Technical Field

[0001] This invention relates to the field of livestock and poultry breeding technology, specifically to a deodorization adsorption device and treatment method for the ventilation opening of livestock and poultry breeding houses. Background Technology

[0002] Livestock and poultry mainly refer to various animals that have been domesticated through long-term labor to meet human needs for meat, eggs, milk, fur, etc. They are very different from wild animals, mainly in the following four aspects: they have been artificially raised for a long time and widely used in production; their phenotypes have undergone essential changes from wild animals, and they have stable economic traits selected by artificial selection; they have formed a stable disease prevention and control system; and they conform to international practices.

[0003] With the increasing intensification of livestock and poultry farming, the emission of livestock and poultry manure and odors has increased significantly, making traditional manure treatment technologies unsuitable for the current high-speed development of the livestock and poultry farming industry. The air inside the pens is an indispensable environmental factor for the survival, growth, and production of livestock and poultry, and the quality of the air has a direct or indirect impact on the survival status, growth process, and production performance of livestock and poultry. At the same time, the odor emitted by livestock and poultry farms affects the quality of the surrounding ecological environment.

[0004] Currently, in the process of livestock and poultry farming, workers install ventilation fans above the livestock sheds to extract air from the sheds and vent it to the outside, maintaining air circulation and providing a comfortable living environment for the animals. However, the animals defecate in the sheds, which easily leads to foul odors. The fans extract these odors without deodorizing or absorbing them, causing unpleasant smells around the sheds, polluting the surrounding environment, and affecting the daily work of the workers. Even if workers clean the livestock and poultry sheds, the odors remain inside the fans after passing through them, and the fans will still expel the odors when they are turned on, making it inconvenient to deodorize and clean the inside of the fans. Summary of the Invention

[0005] The purpose of this invention is to provide a deodorizing adsorption device for the ventilation outlet of livestock and poultry breeding houses, so as to solve the problems mentioned in the background art.

The first motor is fixed to the top of the housing, and the output shaft of the first motor extends into the interior of the housing. The rotating rod is disposed inside the housing, and its left and right ends extend into the outside of the housing and are rotatably connected to the housing. The first bevel gear is fixed to the bottom end of the first motor output shaft, and the second bevel gear is fixed to one side of the rotating rod surface, with the first and second bevel gears meshing together. The connecting rod is fixed to the left and right sides of the rotating rod surface, and the rotating block is fixed to the end of the connecting rod away from the rotating rod.

[0010] Preferably, guide grooves are provided on the lower part of the left and right surfaces of the movable frame, and guide blocks are slidably connected inside the guide grooves. One side of the rotating block is rotatably connected to the guide block.

[0011] Preferably, the lifting structure includes a second motor, a threaded rod, a threaded sleeve, and a through groove. The second motor is fixed to the top of the inner wall of the fixed box. The threaded rod is rotatably connected to the inside of the fixed box, and the top end of the threaded rod is fixedly connected to the output shaft of the second motor.

[0014] Preferably, a mounting plate is bolted to the front side of the movable frame, and the mounting bracket and the mounting plate are slidably connected, with an exhaust fan fixed inside the mounting plate.

[0015] A method for treating odors using a deodorizing adsorption device at the ventilation outlet of a livestock and poultry breeding shed, the method comprising the following steps:

[0016] A: When the fan is turned on for daily ventilation of the livestock and poultry shed, the fan inside the fan draws in the air. The air then comes into contact with the deodorization structure inside the mounting frame. The filter at the rear first filters out impurities in the air, while the activated carbon filter layer adsorbs and purifies the odor in the air. When the air comes into contact with the photocatalytic filter layer, the photocatalytic filter layer effectively treats bacteria in the air. The purified air then passes through the deodorization structure and is discharged outdoors. During the purification process, staff can also turn on the exhaust fan to speed up the exhaust of air from the livestock and poultry shed, thereby completing the exhaust and deodorization purification of the air inside the livestock and poultry shed.

[0017] B: When the blower body needs deodorization and cleaning after a period of use, the operator first turns on the first motor on top of the box, causing the output shaft of the first motor to drive the first bevel gear to rotate. Because the first bevel gear meshes with the second bevel gear, the rotating rod begins to rotate. The connecting rod drives the rotating block to move. While the guide block slides inside the guide groove, the rotating block causes the movable frame to flip, thus opening the front of the fixed frame. Then, the operator can turn on the second motor inside the fixed box, causing the output shaft of the second motor to drive the threaded rod below to rotate. Because the threaded sleeve and the threaded rod are connected by threads... Next, the threaded sleeve rises on the surface of the threaded rod, driving the connecting frame to rise. The mounting box slowly moves upward on the front side of the fixed frame. At the same time, the staff turns on the water pump on one side, so that the water pump draws the deodorant inside the water tank into the water hose and into the interior of the mounting box. Then the nozzle discharges the deodorant water mist, which is sprayed into the interior of the blower body. The staff controls the rotation direction of the output shaft of the second motor, so that the mounting box moves back and forth in the up and down direction to deodorize and clean the blower itself. After a period of time, the staff lowers the mounting box to its original position and flips the movable frame back to its original position to complete the deodorization and cleaning operation of the blower itself.

[0018] C: When the staff needs to clean and replace the deodorizing material of the device, the staff first turns on the first motor on the box again, causing the movable frame to flip. Then, the staff uses tools to remove the fixing bolts on both sides of the movable frame. After disassembly, the staff can pull the mounting frame to remove it from the inside of the movable frame. After removing the mounting frame, the staff can remove the filters on the front and back sides of the mounting frame, replace the filling inside the mounting frame, and clean the removed filters. After replacing the deodorizing material and cleaning the filters, the staff can put the mounting frame back into the movable frame and turn on the first motor, causing the movable frame to flip back to its original position. Then, the staff can turn on the fan body to continue the ventilation and deodorization operation in the livestock and poultry breeding house.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention can deodorize and adsorb air in livestock and poultry sheds, purifying the emitted odors before release to prevent pollution of the surrounding environment. Furthermore, the device has a cleaning function, automatically cleaning the inside of the blower to further improve its deodorization effect and increase its practicality. The device also allows for convenient periodic disassembly and replacement of the deodorizing adsorption material, providing convenience for staff. It not only solves the problem of existing livestock and poultry shed blowers directly emitting air into the shed, easily causing environmental pollution, but also addresses the issue of odors easily adhering to the inside of the blower when extracting air, affecting its subsequent use.

[0035] The adjustment structure 8 includes a first motor 81, a rotating rod 82, a first bevel gear 83, a second bevel gear 84, a connecting rod 85, and a rotating block 86. The first motor 81 is fixed to the top of the box 7, and the output shaft of the first motor 81 extends through the interior of the box 7. The rotating rod 82 is located inside the box 7, and its left and right ends extend through the outside of the box 7 and are rotatably connected to the box 7. The first bevel gear 83 is fixed to the bottom end of the output shaft of the first motor 81. The second bevel gear 84 is fixed to one side of the surface of the rotating rod 82, and the first bevel gear 83 and the second bevel gear 84 mesh with each other. The connecting rod 85 is fixed to the left and right sides of the surface of the rotating rod 82. The rotating block 86 is fixed to the end of the connecting rod 85 away from the rotating rod 82. In this embodiment, the movable frame 3 on the front side of the fixing frame 2 can be flipped, thereby adjusting the position of the movable frame 3 so that the mounting box 9 can be moved up and down to perform deodorization operation inside the fan.

[0036] Guide grooves 16 are provided on the lower part of the left and right sides of the movable frame 3. Guide blocks 17 are slidably connected inside the guide grooves 16. One side of the rotating block 86 is rotatably connected to the guide block 17. In this embodiment, during the flipping of the movable frame 3, the position of the rotating block 86 will change, and the guide block 17 can slide inside the guide groove 16 so as to adjust the movable frame 3 to the correct position.

[0037] The lifting structure 13 includes a second motor 131, a threaded rod 132, a threaded sleeve 133, and a through groove 134.

In this embodiment, it can automatically spray deodorant into the interior of the blower, thereby effectively deodorizing the interior of the blower.

[0040] The front side of the movable frame 3 is bolted with a mounting plate 21, and the mounting bracket 4 is slidably connected to the mounting plate 21. An exhaust fan 22 is fixed inside the mounting plate 21. In this embodiment, when the fan body 1 is turned on, the exhaust fan 22 can also perform air extraction from the outside, which facilitates the rapid exhaust of air from the livestock and poultry breeding house.

[0041] A method for treating odors using a deodorizing adsorption device at the ventilation outlet of a livestock and poultry breeding shed, the method comprising the following steps:

[0042] A: When the blower body 1 is turned on for daily ventilation of the livestock and poultry breeding house, the fan inside the blower body 1 draws in the air from the livestock and poultry breeding house. The air then comes into contact with the deodorization structure 5 inside the mounting frame 4. The filter screen 51 at the rear first filters the impurities in the air, while the activated carbon filter layer 52 adsorbs and purifies the odor in the air of the livestock and poultry breeding house. When the air comes into contact with the photocatalytic filter layer 53, the photocatalytic filter layer 53 effectively treats the bacteria in the air. Then, the purified air passes through the deodorization structure 5 and is discharged to the outside. During the purification process, the staff can also turn on the exhaust fan 22 to speed up the exhaust speed of the air in the livestock and poultry breeding house, thereby completing the exhaust and deodorization purification operation of the air inside the livestock and poultry breeding house.

[0043] B: When the blower body 1 needs to be deodorized and cleaned after a period of use, the operator first turns on the first motor 81 above the box 7, causing the output shaft of the first motor 81 to drive the first bevel gear 83 to rotate. Since the first bevel gear 83 meshes with the second bevel gear 84, the rotating rod 82 starts to rotate. The connecting rod 85 drives the rotating block 86 to move. While the guide block 17 slides inside the guide groove 16, the rotating block 86 drives the movable frame 3 to flip, thereby opening the front side of the fixing frame 2. Then the operator can turn on the second motor 131 inside the fixing box 12, causing the output shaft of the second motor 131 to drive the threaded rod 132 below to rotate. Since the threaded sleeve 133 and the threaded rod 132 rotate, the second motor 131 can be turned on. The threaded connection between the two is such that the threaded sleeve 133 rises on the surface of the threaded rod 132, driving the connecting frame 14 to rise. The mounting box 9 slowly moves up in front of the fixed frame 2. At the same time, the staff turns on the water pump 152 on one side, so that the water pump 152 draws the deodorant inside the water tank 151 into the water hose 153 and into the interior of the mounting box 9. Then the nozzle 11 discharges the deodorant water mist, which is sprayed into the interior of the blower body 1. The staff controls the rotation direction of the output shaft of the second motor 131, so that the mounting box 9 moves back and forth in the up and down direction to deodorize and clean the blower itself. After a period of time, the staff lowers the mounting box 9 to its original position and flips the movable frame 3 back to its original position to complete the deodorization and cleaning operation of the blower itself.

[0044] C: When the staff needs to clean and replace the deodorizing material of the device, the staff first turns on the first motor 81 on the box 7 again, causing the movable frame 3 to flip. Then, the staff uses tools to remove the fixing bolts 63 on both sides of the surface of the movable frame 3. After disassembly, the staff can pull the mounting frame 4 to pull it out from the inside of the movable frame 3. After removing the mounting frame 4, the staff can remove the filter screens 51 on the front and back sides of the mounting frame 4, replace the filling inside the mounting frame 4, and clean the removed filter screens 51. After the deodorizing material is replaced and the filter screens 51 are cleaned, the staff can put the mounting frame 4 back into the movable frame 3 and turn on the first motor 81 to make the movable frame 3 flip back to its original position. Then, the staff can turn on the fan body 1 to continue the ventilation and deodorization operation of the air in the livestock and poultry breeding house.

8. A method for treating odors at the ventilation openings of livestock and poultry breeding sheds using a deodorizing adsorption device, comprising the deodorizing adsorption device for the ventilation openings of livestock and poultry breeding sheds as described in any one of claims 1-7, characterized in that: The processing method includes the following steps: A: When the fan body (1) is turned on and daily ventilation is carried out in the livestock and poultry breeding house, the fan inside the fan body (1) draws in the air in the livestock and poultry breeding house. The air in the livestock and poultry breeding house then comes into contact with the deodorization structure (5) inside the mounting frame (4). The filter screen (51) located at the rear first filters the impurities in the air, while the activated carbon filter layer (52) adsorbs and purifies the odor in the air of the livestock and poultry breeding house. When the air comes into contact with the photocatalytic filter layer (53), the photocatalytic filter layer (53) will effectively treat the bacteria in the air. Then the purified air passes through the deodorization structure (5) and is discharged to the outside. During the purification process, the staff turns on the exhaust fan (22) to speed up the exhaust speed of the air in the livestock and poultry breeding house, so as to complete the exhaust and deodorization purification operation of the air inside the livestock and poultry breeding house. B: When the blower body (1) needs to be deodorized and cleaned after a period of use, the staff first turns on the first motor (81) above the box (7), so that the output shaft of the first motor (81) drives the first bevel gear (83) to rotate. Since the first bevel gear (83) meshes with the second bevel gear (84), the rotating rod (82) starts to rotate. The connecting rod (85) drives the rotating block (86) to move. While the guide block (17) slides inside the guide groove (16), the rotating block (86) drives the movable frame (3) to flip, thereby opening the front side of the fixed frame (2). Then the staff turns on the second motor (131) inside the fixed box (12), so that the output shaft of the second motor (131) drives the threaded rod (132) below to rotate. Since the threaded sleeve (133) and the thread The rods (132) are connected by threads, and the threaded sleeve (133) rises on the surface of the threaded rod (132), driving the connecting frame (14) to rise. The mounting box (9) slowly moves up in front of the fixed frame (2). At the same time, the staff turns on the water pump (152) on one side, so that the water pump (152) draws the deodorant inside the water tank (151) into the water hose (153) and into the interior of the mounting box (9). Then the nozzle (11) discharges the deodorant water mist, and the water mist sprays into the interior of the blower body (1). The staff controls the rotation direction of the output shaft of the second motor (131), so that the mounting box (9) moves back and forth in the up and down direction to deodorize and clean the blower itself. After a period of time, the staff moves the mounting box (9) down to its original position and flips the movable frame (3) back to its original position to complete the deodorization and cleaning operation of the blower itself. C: When the staff needs to clean and replace the deodorizing material of the device, the staff first turns on the first motor (81) on the box (7) again, so that the movable frame (3) flips over. Then the staff uses tools to remove the fixing bolts (63) on both sides of the surface of the movable frame (3). After disassembly, the staff pulls the mounting frame (4) and pulls the mounting frame (4) out of the movable frame (3). After the staff removes the mounting frame (4), the staff removes the filter screens (51) on the front and back sides of the mounting frame (4), replaces the filling material inside the mounting frame (4), and cleans the removed filter screens (51). After the deodorizing material is replaced and the filter screens (51) are cleaned, the staff puts the mounting frame (4) back into the movable frame (3) and turns on the first motor (81) so that the movable frame (3) flips back to its original position. Then the staff can turn on the fan body (1) and continue to ventilate and deodorize the air in the livestock and poultry breeding house.
