Description

Technical Field

[0001] This invention belongs to the field of environmental protection technology, and in particular relates to a windbreak and dust suppression device for aquaculture farms. Background Technology

[0002] Currently, with the development of the livestock industry, environmental pollution from farms is becoming increasingly serious. To ensure animal health, various ventilation systems, such as tunnel systems, have been widely used in livestock farms. The polluted air discharged from livestock farms not only contains a large amount of dust particles but also many harmful gases produced by feces, such as hydrogen sulfide, ammonia, and methane. Harmful gases adhere to dust particles, forming microbial aerosols that enter the human body through respiration, causing a series of respiratory diseases. Therefore, it is necessary to reduce the dispersion of dust particles and harmful gases from livestock farms into adjacent areas.

[0003] Existing windbreak and dust suppression devices mainly use filter meshes to block particulate matter, allowing gas to pass through the mesh and achieve gas-solid separation. However, most of these devices suffer from poor filtration efficiency and high pressure drop; furthermore, the mechanical properties of the filter devices are poor, making them prone to breakage in strong winds, thus reducing their lifespan; in addition, general windbreak and dust suppression devices cannot adjust their angle according to wind direction, resulting in inefficient removal of dust particles and harmful gases.

[0004] In recent years, inspired by nature, many scholars have conducted extensive research on the structures of plants and animals. Studies have found that the hair-like structures and grooves on the surface of cacti can effectively adsorb dust particles, and these adsorbed particles are not easily resuspended. Furthermore, rainwater can wash away the dust particles on the surface, restoring its dust-trapping function. In addition, honeycomb structures exhibit excellent performance in terms of fracture toughness, impact resistance, heat dissipation, vibration reduction, and noise reduction. Introducing a triangular configuration at each vertex of a regular dodecagonal honeycomb can further enhance the material's mechanical properties. Summary of the Invention

[0005] The purpose of this invention is to provide a windbreak and dust suppression device for aquaculture farms. The device can automatically adjust its angle according to the wind direction, effectively regulate the airflow trajectory, enhance the removal effect on particles of all levels, and also have good mechanical properties and stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A windbreak and dust suppression device for a farm includes a filtration mechanism, a rotating mechanism for driving the filtration mechanism to rotate, and a base 4. The filtration mechanism includes a filter wall and a housing 2. The filter wall is formed by multiple tubular channels 6 with dodecagonal outer walls and circular inner walls arranged axially in parallel. One tubular channel 6 and six adjacent tubular channels 6 form six equilateral triangles. Multiple radially staggered filter baffles 7 are arranged inside the tubular channels 6. The width of the surface of the arc is greater than the width of the chord surface. The surface of the arc is fixedly connected to the inner wall of the tubular channel 6. The chord surfaces of the filter baffles 7 are all parallel. Multiple biomimetic cactus cones 8 with circular top surfaces and square bottom surfaces are arranged on the filter baffles 7. Multiple biomimetic cactus spines 3 are arranged on the top surface of the biomimetic cactus cones 8. An exhaust hole 5 is opened behind the filter wall on the housing 2. The lower surface of the housing 2 is connected to the rotating mechanism, which is installed inside the base 4.

[0007] As a preferred technical solution of the present invention, the rotating mechanism includes a motor 13, which is connected to the driving bevel gear 12 through a reducer. The driven bevel gear 11 is sleeved on the rotating shaft 10. The rotating shaft 10 is connected to the slewing bearing 9 on the base 4 through a gear drive. The slewing bearing 9 is fixedly connected to the lower surface of the housing 2.

[0008] As a more preferred technical solution of the present invention, the biomimetic cactus cone 8 is covered with the surface of the filter baffle 7.

[0009] As a preferred technical solution of the present invention, a wind direction sensor 1 is installed on the upper surface of the housing 2.

[0010] As a preferred technical solution of the present invention, the side length of the equilateral triangle is 15-20cm.

[0011] As a preferred technical solution of the present invention, the regular dodecagon has a side length of 15 cm and the inner diameter of the tubular channel is 60 cm.

[0012] As a preferred technical solution of the present invention, the number of filter baffles 7 is 6-10.

[0013] As a preferred technical solution of the present invention, the side length of the square is 3 cm and the diameter of the circle is 2 cm.

[0014] As a more preferred technical solution of the present invention, the biomimetic spike 3 is covered with the circular top surface of the biomimetic cactus cone 8. The biomimetic spike 3 is a cone with an angle of 15° between the generatrix and the axis, and the base radius is 1.5mm.

[0015] As a more preferred technical solution of the present invention, the exhaust hole 5 occupies 30% of the rear side area of ​​the housing 2.

[0016] As a preferred technical solution of the present invention, the filter baffle 7, the bionic cactus cone 8 and the bionic cactus spine 3 are made of hard plastic or metal.

[0017] As a preferred technical solution of the present invention, the space of the triangle is filled with an adsorbent material.

[0018] Compared with existing technologies, the following beneficial effects can be achieved: The device provided by this invention has good impact resistance, vibration reduction, and noise reduction performance, and can operate stably even in strong winds. It enhances the turbulent motion of dust-laden airflow in the filtration channel, increases the effective collision between particles and filter baffles, and improves the overall filtration effect of the device. It retains particles more efficiently and reduces secondary entrainment of particles by the airflow. It is easier to remove internally retained particles and quickly and completely restores the dust retention capacity of the device. The triangular connection can be filled with reusable modified activated carbon, which more effectively adsorbs harmful gases in the dust-laden airflow to achieve multi-stage filtration. The wind direction is monitored in real time by a wind speed sensor, and the rotation device turns the filter wall so that it is always facing the wind, thereby enhancing the filtration and windproof effect of the device.

Multiple biomimetic cactus spines 3 are arranged on the top surface of the biomimetic cactus cones 8. An exhaust hole 5 is opened behind the filter wall on the housing 2. The lower surface of the housing 2 is connected to the rotating mechanism, which is installed inside the base 4.

[0048] The filtration efficiency of individual filter mechanisms constituting the filter wall in the device in the above embodiments was tested. The PM 2.5 and PM 10 filtration efficiencies of the individual filter mechanism sample in Embodiment 1 were 91.7% and 89.4% respectively (dust-laden airflow velocity 3m / s), which were 28.1% higher than those of the comparative embodiment and 39.3% higher than those of the comparative embodiment.
