Description

Technical Field

[0001] This utility model belongs to the technical field of air purification equipment for livestock farming, specifically relating to a deodorizing device for chicken coops used in livestock farming. Background Technology

[0002] Currently, in large-scale egg-laying hen farming, chicken houses, as enclosed or semi-enclosed spaces where laying hens reside for extended periods, continuously produce irritating gases such as ammonia and hydrogen sulfide from hen manure through microbial decomposition. These gases not only have a strong odor but can also potentially affect the immunity and egg production rate of laying hens, and even trigger outbreaks of disease. Therefore, the internal environment of the chicken house directly affects the healthy growth and productivity of the flock, and is one of the most pressing issues to be addressed in large-scale farming.

[0003] Currently, the industry primarily uses ventilation to address odors in chicken houses. However, this method directly releases untreated exhaust gases, easily causing secondary pollution to the surrounding environment. Furthermore, ventilation equipment relies on data from fixed gas detection points for manual start-up and shutdown. Due to factors such as airflow disturbances within the chicken house and uneven distribution of chicken droppings, the concentration of irritating gases varies significantly across different areas. This makes it impossible to target high-concentration areas for purification, resulting in odor residue in some areas and ultimately affecting ventilation effectiveness.

[0004] Therefore, designing a mobile chicken coop deodorization device to effectively solve the odor problem in chicken coops is particularly important. This not only ensures that the air quality inside the chicken coop and the exhaust air meet standards, reducing environmental pollution, but also improves the scale of development of the poultry industry.

[0007] As a further explanation and limitation of the above technical solution, the electric moving seat includes a housing and a bolted base plate, and the lithium battery and controller are both installed inside the housing. Sliders corresponding to the track mounting plate are symmetrically arranged on both sides of the housing. A gear transmission mechanism is provided on the housing, and a rack is installed on the track mounting plate. The gear transmission mechanism is driven by a stepper motor and meshes with the rack.

[0008] As a further explanation and limitation of the above technical solution, the gear transmission mechanism includes a worm and a meshing worm wheel, a driving gear and a meshing driven gear. The worm wheel and the driving gear are mounted in the housing through a first rotating shaft, and the driven gear is mounted in the housing through a second rotating shaft and meshes with a rack. One end of the worm is fixedly connected to the output shaft of the stepper motor, and the other end is mounted on a support plate through a bearing support. The support plate is fixed in the housing.

[0010] As a further explanation of the above technical solution, rollers are provided on the housing, and the rollers are in contact with the plane of the track mounting plate.

[0011] As a further explanation and limitation of the above technical solution, the deodorizer includes a housing and protective nets installed on its front and rear sides via a panel frame. An exhaust fan is installed inside the housing. The motor of the exhaust fan is powered by a lithium battery and is controlled by a controller and an environmental sensor through signal interlocking. Activated carbon adsorption plates and zeolite adsorption plates are installed inside the housing via a plug-in frame, and all adsorption plates are located on the air inlet side of the exhaust fan.

The electric push rod is installed between the two connecting seats. The electric push rod is powered by a lithium battery and the extension and retraction of the push rod is controlled by a controller.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model utilizes the activated carbon adsorption plate and zeolite adsorption plate inside the deodorizer to adsorb and purify odorous gases such as ammonia and hydrogen sulfide. The treated air is then discharged by the ventilation fan, effectively solving the problem that the direct discharge of untreated waste gas by existing ventilation methods can easily cause secondary pollution to the surrounding environment.

[0016] 2. This utility model utilizes a track mounting plate and an electrically movable seat slidably connected to it. The electrically movable seat is driven by a rack and pinion mechanism and utilizes a slider in cooperation with the track mounting plate.

[0017] 3. This invention uses a lithium battery power supply, ensuring flexible equipment movement without being restricted by power cords. The controller receives signals from environmental sensors and interlocks to control the stepper motor to drive the electric moving base, the electric push rod to adjust the height of the deodorizer, and the start and stop of the ventilation fan, all without manual intervention. Therefore, it completely solves the problems of existing technologies that rely on manual start and stop of ventilation equipment, resulting in high labor intensity and difficulty in dynamically adjusting according to odor concentration.

[0018] 4. This utility model features an operating port with a heat dissipation perforation plate on the casing, facilitating the inspection and heat dissipation of internal components; an inspection door is provided on the side of the deodorizer, allowing for quick replacement of the activated carbon adsorption plate and zeolite adsorption plate, greatly improving maintenance efficiency. Furthermore, the heat dissipation perforation plate design effectively prevents overheating of the equipment, extending its service life. Attached Figure Description

[0030] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figure 1-6 We used 300m 2 Taking a chicken coop as an example, this utility model will be further explained through two embodiments based on actual conditions. Example 1

[0031] As attached Figures 1 to 4As shown, a chicken coop deodorization device for poultry farming mainly consists of a track mounting plate 1, an electric moving base 2, a telescopic component 3, a deodorizer 4, an electric push rod 5, and an environmental sensor 6. The track mounting plate 1 is fixed below the top steel beam along the length of the chicken coop. The electric moving base 2 specifically includes a housing 201 and a base plate 202 connected by bolts. A lithium battery 12 and a controller 13 are installed inside the housing 201. The lithium battery 12 powers the entire device, and the controller 13, as the core control unit, receives signals from the environmental sensor 6 and controls the operation of each component. Sliding blocks 7 are symmetrically arranged on both sides of the housing 201. The electric moving base 2 is slidably connected to the track mounting plate 1 via the sliding blocks 7, allowing it to move along the length of the track. Rollers 14 are also provided on the top of the housing 201, contacting the plane of the track mounting plate 1 to effectively reduce frictional resistance during movement. The housing 201 houses a gear transmission mechanism 9 and a stepper motor 10. A rack 8 is fixedly mounted on the track mounting plate 1. The gear transmission mechanism 9 meshes with the rack 8 to enable the electric moving seat 2 to move along the track mounting plate 1. Specifically, the gear transmission mechanism 9 consists of a worm 901, a worm wheel 902, a driving gear 904, and a driven gear 906. One end of the worm 901 is connected to the output shaft of the stepper motor 10, and the other end is mounted on a support plate 205 via a bearing support 11. The support plate 205 is fixed inside the housing 201. The worm wheel 902 and the driving gear 904 are coaxially arranged via a first rotating shaft 903. The worm wheel 902 meshes with the worm 901, and the driving gear 904 meshes with the driven gear 906. The driven gear 906 is mounted inside the housing 201 via a second rotating shaft 905 and meshes with the rack 8. When the stepper motor 10 starts, the power output of the stepper motor 10 is reduced by the worm gear 901 and worm wheel 902 and then transmitted to the drive gear 904. The drive gear 906 then drives the electric moving seat 2 to move along the track mounting plate 1 through the meshing of the driven gear 906 and the rack 8. The driver of the stepper motor 10 is electrically connected to the controller 13 through the wire and is controlled by the PWM signal of the controller 13. It can automatically adjust the start and stop according to the odor concentration in the chicken house and the preset program.

[0032] As attached Figure 5 and 6As shown, the main body of the deodorizer 4 is a box 401. Protective nets 403 are installed on the front and back sides of the box 401 via panel frames 402 to prevent debris from the chicken coop from entering the box 401. The protective nets 403, which are metal mesh structures, are fixed to the front and back sides of the box 401 via panel frames 402 to prevent debris from the chicken coop from entering the box 401. An exhaust fan 404 is fixed inside the box 401. The motor of the exhaust fan 404 is electrically connected to the lithium battery 12 and the controller 13 via wires, and its start and stop are controlled by the controller 13. An insert frame 405 is also provided inside the box 401. Activated carbon adsorption plates 406 and zeolite adsorption plates 407 are detachably installed on the insert frame 405. These plates are arranged sequentially along the air intake direction of the exhaust fan 404 and are both located on the air intake side of the exhaust fan 404. In the above implementation process, the activated carbon adsorption plate 406 was purchased from Jiahe Environmental Technology Co., Ltd. as the JAF-051 model, which has a specific surface area ≥1500m². 2 / g; The zeolite adsorption plate 407 was purchased from the SD-FZ01 model manufactured by Shandong Shendun Environmental Protection Technology Co., Ltd., with an adsorption capacity for ammonia ≥15mg / g. When those skilled in the art select other models of adsorption plates to replace the adsorption plate in this embodiment, it should be considered an equivalent solution and falls within the scope of protection of this invention.

[0033] Furthermore, an inspection door 408 is connected to the side of the housing 401 via a hinge. Opening the inspection door 408 allows for easy replacement of the activated carbon adsorption plate 406 and the zeolite adsorption plate 407, ensuring long-term purification performance.

[0034] like Figure 1 , 4 As shown in Figure 5, the telescopic assembly 3 includes two upper connecting rods 301 and two lower connecting rods 302. The four connecting rods are divided into two groups. One end of each group of upper connecting rods 301 and lower connecting rods 302 is hinged to each other through a connecting seat 303. The other end of each group of upper connecting rods 301 is fixed to the base plate 202 through a first hinge seat 15. The other end of each group of lower connecting rods 302 is fixed to the top of the box 401 through a second hinge seat 16. The electric push rod 5 is installed between the two connecting seats 303, powered by a lithium battery 12, and its extension and retraction are controlled by a controller 13. This drives the relative movement of the upper connecting rods 301 and lower connecting rods 302 or keeps them stationary, thereby realizing the height adjustment of the deodorizer 4 to adapt to the height requirements of different chicken houses and ensure the best purification effect.

[0035] In this embodiment, the environmental sensor 6 is an MQ-135 air quality sensor with a detection range of 10ppm-10000ppm and a sensitivity of ≥10ppm for gases such as ammonia and hydrogen sulfide; the controller 13 is an STM32F103C8T6 microcontroller with a built-in 12-bit ADC module, which can convert the analog signal from the environmental sensor 6 into a digital signal and output a control signal according to a preset threshold. The circuit connection method in the specific implementation is as follows: The positive output terminal of the lithium battery 12 is electrically connected to the VCC pin of the controller 13, the power input terminal of the stepper motor driver, the positive terminal of the motor of the ventilation fan 404, and the positive power terminal of the electric push rod 5, respectively; the negative output terminal of the lithium battery 12 is electrically connected to the GND pin of the controller 13, the ground terminal of the stepper motor driver, the negative terminal of the motor of the ventilation fan 404, and the ground terminal of the electric push rod 5, forming a common ground loop; the signal output terminal of the environmental sensor 6 is electrically connected to the PA0 pin of the controller 13; the PB0-PB3 pins of the controller 13 are electrically connected to the control signal input terminal of the stepper motor driver through wires; the PC0 pin of the controller 13 is connected in series with the motor of the ventilation fan 404 through a relay module; the PC1 pin of the controller 13 is connected in series with the control terminal of the electric push rod 5 through a relay module.

[0036] It should be noted that, in order to adapt to the driving force requirements of longer connecting rods and extend the adjustment range of telescopic component 3 to 0.8m~1.5m, we can replace the electric push rod 5 with a model with a thrust ≥2000N. However, a 5Ω current-limiting resistor needs to be connected in series between the electric push rod 5 and the controller 13 to match the working current of the model and ensure that the deodorizer 4 can effectively purify the air in different height environments.

[0037] Its working principle is as follows: The controller 13 outputs a control signal according to a preset program, starts the stepper motor 10 to move the electric moving seat 2 along the track mounting plate 1, and stops at different detection points. Then, according to the program, the electric push rod 5 drives the telescopic component 3 to adjust the deodorizer 4 to a preset height. The environmental sensor 6 detects the odor concentration in the chicken house in real time and transmits the detection signal to the controller 13. When the detected value exceeds the preset threshold of 50ppm, the ventilation fan 404 is started. Air enters the box 401 through the protective net 403 under the action of the ventilation fan 404, and is purified by adsorption through the activated carbon adsorption plate 406 and the zeolite adsorption plate 407 before being discharged, thus removing odors. When the environmental sensor 6 detects that the odor concentration is below 50ppm, the controller 13 controls the ventilation fan 404 to stop working. The stepper motor 10 is started again to move the electric moving seat 2 to the next detection point, and the above process is repeated to ensure that the odor concentration in the chicken house is always controlled within a safe range. Example 2

[0038] As attached Figure 2As shown, we have an operation port 203 on the housing 201, and a heat dissipation plate 204 is installed at the operation port 203. This facilitates the maintenance of the internal components of the housing 201 and enables air convection inside and outside the housing 201 through the heat dissipation plate 204, thus preventing the lithium battery 12 and controller 13 from having their service life affected by excessive temperature rise.

[0039] The foregoing has shown and described the main features and advantages of this utility model. It will be apparent to those skilled in the art that the specific embodiments of this utility model are not limited to the details of the exemplary embodiments described above.
