Description

Indoor circulating ventilation system for egg-laying chicken farms Technical Field

[0001] This invention relates to the field of ventilation technology, and more particularly to an indoor circulating ventilation device for laying hen farming. Background Technology

[0002] Laying hens are chickens raised specifically to produce eggs. Unlike broiler chickens, the main focus of raising laying hens is to improve egg quality and maintain or increase egg production, rather than improving chicken meat quality. Eggs are the primary source of income for laying hen farmers.

[0003] In egg-laying hen farming, ventilation is particularly important in high-density chicken houses. Maintaining fresh and well-ventilated air inside the house is essential. Poor ventilation allows large amounts of harmful gases such as ammonia, carbon dioxide, and hydrogen sulfide to be released, affecting the normal growth and egg production of chickens and causing various diseases. Therefore, ventilation devices need to be installed on the walls of the chicken house.

[0004] However, when existing ventilation equipment is in use, dust in the chicken coop enters the ventilation device along with the air. The air is then exhausted to the outside, while the dust remains on the filter plate inside the ventilation device. After long-term use, this dust will clog the mesh of the filter plate and affect the ventilation effect. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an indoor circulating ventilation device for egg-laying hen farming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an indoor circulating ventilation device for laying hen farming, comprising an outer shell and a mounting shell fixedly connected to the outer wall of the outer shell, a mounting frame fixedly installed inside the outer shell, a filter plate slidably installed inside the mounting frame, a cleaning component for cleaning the filter plate slidably installed inside the mounting frame, a cleaning component installed on the top of the outer shell, a control component disposed between the cleaning component and the cleaning component, a storage box installed on the bottom of the outer shell, a recycling component installed between the storage box and the cleaning component, an exhaust component installed inside the mounting shell, a fixing component installed inside the mounting shell and at the front end of the exhaust component, the filter plate being mounted on the top of the storage box via the mounting component, and a blocking component installed at the end of the mounting shell away from the outer shell.

The first stop block is fixedly connected to the inner wall of the water outlet pipe and located at the top of the baffle plate. The second stop block is fixedly connected to the inner wall of the water outlet pipe and located at the bottom of the baffle plate.

[0010] Further: The recycling component includes a return water pipe, a filter screen, a water pump, and a drainage trough. The return water pipe is connected to the storage box and the water tank. The filter screen is fixedly installed at one end of the return water pipe located in the storage box. The water pump is installed inside the return water pipe. The drainage trough is located at the bottom of the mounting frame.

[0011] Further: The exhaust assembly includes a mounting bracket, a protective shell, a drive motor, a drive shaft, and a fan. The mounting bracket is installed inside the mounting shell, the protective shell is fixed inside the mounting bracket, the drive motor is fixedly installed inside the protective shell, the drive shaft is fixedly installed at the output end of the drive motor, and the fan is fixedly installed at the output end of the drive shaft.

[0012] Further: The fixing assembly includes a movable rod, an annular fixing plate, a turntable, a movable groove, a movable column, and a handle. Multiple movable rods arranged in a ring are slidably installed inside the mounting housing. The movable rods are installed inside the mounting housing through grooves opened on the outer wall of the mounting housing. The annular fixing plate is fixedly connected to one end of the movable rod. A turntable is movably installed inside the mounting housing. Multiple movable grooves are arranged in a ring inside the turntable. The movable column is fixedly connected to the end of the movable rod away from the annular fixing plate and corresponds to the movable groove.

[0015] Furthermore, multiple demister plates are fixedly connected to the interior of the mounting bracket and at the end furthest from the filter plate.

[0016] The present invention has the following beneficial effects:

[0017] 1. By setting up a sliding rod, a first cleaning block, a second cleaning block, an electric push rod, a water outlet pipe, a first support block, and a second support block, when the filter plate needs to be cleaned, the electric push rod is activated. The electric push rod drives the first cleaning block to move downward along the sliding rod. When the first cleaning block moves downward, the second cleaning block can open simultaneously, so that when the first cleaning block moves downward, the two second cleaning blocks at the top of the first cleaning block open relative to each other at the same time. When the first cleaning block moves, the second support blocks, without the support of the first support blocks, will be pushed open downward by the gravity of the water flow, allowing the cleaning liquid to enter the top of the filter plate through the water outlet pipe. Then, the dust on the filter plate is cleaned by the brushes at the front of the first and second cleaning blocks. It can be realized that the filter plate can be cleaned by the cooperation of the cleaning liquid and the brushes.

[0018] 2. By setting up a storage box, return water pipe, filter screen, water pump and drain tank, the cleaning solution after cleaning enters the storage box through the drain tank during use. Then, the water pump is turned on to draw the cleaning solution from the storage box into the water tank. When the cleaning solution enters the return water pipe, the filter screen filters out the dust and impurities in the cleaning solution, which can realize the filtration and recycling of the used cleaning solution for reuse, saving resources.

[0032] Referring to Figures 1-11, the indoor circulating ventilation device for laying hen farming provided by the present invention includes an outer shell 1 and an installation shell 2 fixedly connected to the outer wall of the outer shell 1. An installation frame 3 is fixedly installed inside the outer shell 1. A filter plate 4 is slidably installed inside the installation frame 3. A cleaning component 5 for cleaning the filter plate 4 is slidably installed inside the installation frame 3. A cleaning component 6 is installed on the top of the outer shell 1. A control component 7 is provided between the cleaning component 5 and the cleaning component 6. A storage box 8 is installed at the bottom of the outer shell 1. A recycling component 9 is installed between the storage box 8 and the cleaning component 6. An exhaust component 10 is installed inside the installation shell 2. A fixing component 11 is installed inside the installation shell 2 and at the front end of the exhaust component 10. The filter plate 4 is installed on the top of the storage box 8 through the installation component. A blocking component 13 is installed at the end of the installation shell 2 away from the outer shell 1.

[0033] First, the device is fixedly installed on the wall of the chicken coop using the fixing component 11. Then, when in use, the exhaust component 10 is turned on to draw air from the chicken coop into the device. The air enters the outer casing 1, where dust is blocked by the filter plate 4, and the air is discharged to the outside through the mounting casing 2. When the filter plate 4 needs to be cleaned, the cleaning component 5 is turned on. While the cleaning component 5 is operating, the washing component 6 is turned on by the control component 7. The washing component 6 sprays water onto the filter plate 4, working in conjunction with the cleaning component 5 to clean the dust off the filter plate 4. The wastewater used during use is filtered and recycled by the recycling component 9 for reuse. When the device is turned off, the blocking component 13 prevents external debris from entering the device and causing damage.

[0034] The cleaning assembly 5 includes a slide bar 501, a first cleaning block 502, a second cleaning block 503, a slide groove 504, a slider 505, a support rod 506, a first spring 507, a support plate 508, an electric push rod 509, and a brush 510. Two symmetrically distributed slide bars 501 are fixedly connected inside the mounting bracket 3. The first cleaning block 502 is slidably mounted on the outer wall of the slide bar 501 through sliding holes at both ends. Two second cleaning blocks 503 are symmetrically distributed and movably mounted on top of the first cleaning block 502. Two symmetrically distributed slide grooves 504 are also present. Furthermore, a slider 505 is slidably mounted inside the first cleaning block 502, a support rod 506 is movably mounted on the top of the slider 505, a first spring 507 is mounted inside the slide groove 504 and located at the rear end of the slider 505, the top of the support rod 506 is movably mounted on the end of the second cleaning block 503 away from the first cleaning block 502, a support plate 508 is fixedly connected to one side of the first cleaning block 502, and an electric push rod 509 is fixedly mounted on the top of the support plate 508. The top of the support plate 508 is fixedly mounted on... On the inner wall of the outer casing 1, brushes 510 are fixedly installed at the front ends of the first cleaning block 502 and the second cleaning block 503. In use, the electric push rod 509 is activated, causing the first cleaning block 502 to move downwards along the slide rod 501. As the first cleaning block 502 moves downwards, the top of the second cleaning block 503 is no longer obstructed by the mounting bracket 3, allowing the first spring 507 to push the slider 505 forward in the slide groove 504. Through the cooperation of the slider 505 and the support rod 506, one end of the second cleaning block 503 is pushed upwards. This allows the two second cleaning blocks 503 at the top of the first cleaning block 502 to simultaneously unfold relative to each other when the first cleaning block 502 moves downward. When the first cleaning block 502 moves upward, the second cleaning blocks 503 contact the top of the mounting bracket 3 and then continue to move upward to press the second cleaning blocks 503 back to their pre-use state. When the first cleaning block 502 and the second cleaning block 503 move on the outer wall of the filter plate 4, the dust on the filter plate 4 is cleaned by the brushes 510 at the front ends of the first cleaning block 502 and the second cleaning block 503.

[0035] The cleaning component 6 includes a water tank 601, a water inlet 602, a water outlet 603, a spray block 604, and spray heads 605. The water tank 601 is installed on the top of the housing 1. The water inlet 602 is located on the top of the water tank 601. The water outlet 603 is fixedly installed on the bottom of the water tank 601. The spray block 604 is installed inside the mounting bracket 3 by bolts. Multiple spray heads 605 are linearly distributed on the bottom of the spray block 604. First, cleaning fluid enters the water tank 601 through the water inlet 602. During use, the control component 7 opens the water outlet 603, and the cleaning fluid in the water tank 601 enters the spray block 604 from the water outlet 603 due to gravity. Then, the cleaning fluid is sprayed onto the top of the filter plate 4 through the spray heads 605. At the same time, the cleaning component 5 cleans the dust on the filter plate 4.

[0036] The control component 7 includes a first support block 701, a rotating shaft 702, a baffle plate 703, a second support block 704, a first stop block 705, and a second stop block 706. The first support block 701 is fixedly connected to the top of the support plate 508. The rotating shaft 702 is installed inside the water outlet pipe 603. One end of the rotating shaft 702 is fixedly connected to the baffle plate 703. The second support block 704 is fixedly connected to the end of the rotating shaft 702 away from the baffle plate 703. The first stop block 705 is fixedly connected to the inner wall of the water outlet pipe 603 and located on top of the baffle plate 703. The second stop block 706 is fixedly connected to the inner wall of the water outlet pipe 603 and located on top of the baffle plate 703. At the bottom, when the cleaning component 5 is closed, the first cleaning block 502 is located at the top of the mounting bracket 3, and the first support block 701 at the top of the support plate 508 is supported at the bottom of the second support block 704. At the same time, the water baffle 703 is placed horizontally through the connection of the rotating shaft 702, so that the cleaning fluid in the water outlet pipe 603 cannot fall. When the cleaning component 5 is opened, the first cleaning block 502 moves downward, and the second support block 704, without the support of the first support block 701, will be pushed downward by the gravity of the water flow, so that the cleaning fluid can pass through the water outlet pipe 603. The first baffle 705 and the second baffle 706 can restrict the position of the water baffle 703.

[0037] The recycling component 9 includes a return water pipe 901, a filter screen 902, a water pump 903, and a drain trough 904. The return water pipe 901 is connected between the storage box 8 and the water tank 601. The filter screen 902 is fixedly installed at one end of the return water pipe 901 located in the storage box 8. The water pump 903 is installed inside the return water pipe 901. The drain trough 904 is located at the bottom of the mounting bracket 3. In use, the cleaning fluid after cleaning enters the storage box 8 through the drain trough 904. Then, the water pump 903 is turned on to draw the cleaning fluid from the storage box 8 into the water tank 601. When the cleaning fluid enters the return water pipe 901, the filter screen 902 filters out the dust and impurities in the cleaning fluid.

[0038] The exhaust assembly 10 includes a mounting frame 1001, a protective shell 1002, a drive motor 1003, a drive shaft 1004, and a fan 1005. The mounting frame 1001 is installed inside the mounting shell 2, and the protective shell 1002 is fixed inside the mounting frame 1001. The drive motor 1003 is fixedly installed inside the protective shell 1002, the drive shaft 1004 is fixedly installed at the output end of the drive motor 1003, and the fan 1005 is fixedly installed at the output end of the drive shaft 1004. In use, the drive motor 1003 is turned on, and the fan 1005 is driven to rotate through the drive shaft 1004. When the fan 1005 rotates, the air inside the chicken coop is drawn into the equipment, filtered by the filter plate 4, and then discharged to the outside.

[0039] The fixing assembly 11 includes a movable rod 1101, an annular fixing plate 1102, a turntable 1103, a movable groove 1104, a movable column 1105, and a handle 1106. Multiple movable rods 1101 arranged in a ring are slidably installed inside the mounting housing 2. The movable rods 1101 are installed inside the mounting housing 2 through grooves opened in the outer wall of the mounting housing 2. The annular fixing plate 1102 is fixedly connected to one end of the movable rod 1101. The turntable 1103 is movably installed inside the mounting housing 2. Multiple movable grooves 1104 are arranged in a ring inside the turntable 1103. The movable column 1105... The handle 1106 is fixedly connected to the end of the moving rod 1101 away from the annular fixed plate 1102 and corresponding to the moving groove 1104. The handle 1106 is fixedly connected to the front end of the turntable 1103. When in use, the mounting shell 2 is installed in the wall. Then, the handle 1106 is rotated downwards. When rotating, the turntable 1103 is rotated. Through the rotation of the turntable 1103, multiple moving rods 1101 slide outwards at the same time, and at the same time, the annular fixed plate 1102 is moved together to fix the equipment in the wall. At the same time, through the weight of the handle 1106 itself, the annular fixed plate 1102 can be continuously opened.

[0040] The mounting assembly includes a fixing groove 1201. The storage box 8 has a fixing groove 1201 inside for mounting the filter plate 4. The filter plate 4 is mounted inside the storage box 8 by bolts. The storage box 8 is mounted to the bottom of the outer casing 1 by bolts. When the filter plate 4 needs to be replaced or installed, the filter plate 4 is installed in the fixing groove 1201 inside the storage box 8, and then the filter plate 4 is fixed inside the storage box 8 by bolts. Then the bottom of the storage box 8 is removed.

[0041] The blocking assembly 13 includes a baffle 1301, a hinge 1302, and a second spring. Two symmetrically distributed baffles 1301 are installed at the air outlet end of the mounting housing 2. The hinge 1302 is installed between the mounting housing 2 and the baffles 1301. The second spring is installed inside the mounting hole on the outer wall of the mounting housing 2 and is connected to the baffles 1301. When the exhaust assembly 10 is closed, the baffles 1301 are closed at the air outlet end of the mounting housing 2 by the second spring. When the exhaust assembly 10 is opened, the baffles 1301 are blown open by the wind force, which can prevent foreign objects from entering the equipment and damaging the equipment when it is not in use.

[0042] Multiple demisting plates 14 are fixedly connected inside the mounting bracket 3 and at the end away from the filter plate 4. When the exhaust assembly 10 and the cleaning assembly 6 are turned on during use, the suction of the exhaust assembly 10 will draw the cleaning liquid in the filter plate 4 toward the exhaust assembly 10. This demisting will block the cleaning liquid and prevent it from falling into the exhaust assembly 10 and causing damage to the equipment.

[0043] Working principle: First, install the mounting shell 2 in the wall. Then, rotate the handle 1106 downwards. This rotation drives the turntable 1103 to rotate, causing multiple moving rods 1101 to slide outwards simultaneously, moving the annular fixing plate 1102 to fix the equipment in the wall. Next, turn on the drive motor 1003, driving the fan 1005 to rotate, drawing air from the chicken coop into the equipment. The air enters the outer shell 1, where dust is blocked by the filter plate 4, while the air is discharged to the outside through the mounting shell 2. When cleaning the filter plate 4 is needed, activate the electric push rod 509. The electric push rod 509 drives the first cleaning block 502 to move downwards along the slide rod 501. When the first cleaning block 502 moves downward, the second cleaning block 503 can open simultaneously, so that when the first cleaning block 502 moves downward, the two second cleaning blocks 503 at the top of the first cleaning block 502 open relative to each other at the same time. When the first cleaning block 502 moves, the second support block 704, without the support of the first support block 701, will be pushed downward by the gravity of the water flow, so that the cleaning liquid can pass through the outlet pipe 603 and enter the top of the filter plate 4. Then, the dust on the filter plate 4 is cleaned by the brush 510 at the front end of the first cleaning block 502 and the second cleaning block 503. The wastewater during use is filtered by the filter screen 902 and then pumped into the return pipe 901 by the water pump 903, and then re-injected into the water tank 601.
