Description

Technical Field

[0001] This utility model relates to the field of livestock breeding ventilation technology, and in particular to a livestock breeding ventilation device. Background Technology

[0002] In modern animal husbandry, the air quality of the livestock rearing environment directly affects the livestock's growth rate, health status, and farming efficiency. Traditional livestock sheds typically rely on natural ventilation, exchanging air through windows or vents. However, this method has several problems in practice. For example, ventilation effectiveness is greatly affected by weather conditions, and it cannot effectively filter dust, bacteria, and harmful gases from the outside air, easily leading to respiratory diseases in livestock and even outbreaks of disease. Furthermore, while some farms are equipped with mechanical ventilation equipment, they often lack effective air purification devices, resulting in severe dust accumulation inside the equipment after long-term operation, affecting ventilation efficiency and increasing maintenance difficulty and costs. Therefore, there is an urgent need for a livestock rearing ventilation device with a reasonable structure, strong purification capacity, and easy maintenance to achieve effective filtration and stable delivery of air entering the shed, thereby improving the overall quality of the rearing environment. Therefore, we propose a livestock rearing ventilation device. Utility Model Content

[0003] The main purpose of this utility model is to provide a livestock feeding ventilation device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A livestock breeding ventilation device includes a ventilation pipe that is inserted and connected to the wall of the breeding shed. The upper and lower ends of the ventilation pipe are fixedly connected to a No. 1 triangular reinforcing steel and a No. 2 triangular reinforcing steel that are fixedly connected to the wall of the breeding shed. A fan hood is fixedly connected to the end of the ventilation pipe located inside the breeding shed. A filter assembly is detachably installed inside the ventilation pipe. Four No. 2 connectors for installing the filter assembly are provided on the ventilation pipe. A fan assembly is detachably installed at the end of the ventilation pipe away from the fan hood. Four No. 1 connectors for installing the fan assembly are provided at the end of the ventilation pipe away from the fan hood.

[0006] Preferably, the filter assembly includes a sealing plate, both ends of which are integrally formed with mounting brackets that can be detachably installed with the second connecting piece. One end of the sealing plate is fixedly installed with a first filter screen, a second filter screen, and an activated carbon adsorption screen, with the activated carbon adsorption screen located on the side closer to the hood.

[0007] By adopting the above technical solution, the structural design enables the filter assembly to have good sealing and stability. The sealing plate serves as a supporting base, integrating three different filter materials to achieve multi-stage purification of the incoming air. The activated carbon adsorption mesh is located near the hood, which helps to perform the final odor adsorption treatment before the air enters the breeding shed, thus improving the air purification effect. At the same time, the mounting bracket and the No. 2 connector facilitate the quick installation and disassembly of the entire filter assembly, improving equipment maintenance efficiency.

[0008] Preferably, the second connector includes a guide rod that is fixedly installed with the ventilation duct, and a clamping bolt is threaded through the middle of the guide rod.

[0009] By adopting the above technical solution, a stable and reliable connection method is provided for the filter assembly. The guide rod guides the sliding installation path of the filter assembly, while the tightening bolts adjust the locking force via threads, ensuring that the filter assembly will not loosen or shift during operation. This connection method not only improves installation accuracy but also allows users to easily disassemble the filter assembly for cleaning or filter media replacement as needed, making the operation simple, safe, and reliable.

[0010] Preferably, the mounting bracket has a U-shaped structure, and both the upper and lower parts of the mounting bracket are provided with guide grooves that are slidably connected to the guide rod, and the thickness of the guide grooves is greater than the thickness of the guide rod.

[0011] By adopting the above technical solution: the U-shaped mounting bracket combined with the widened guide groove design makes the installation process smoother, and makes it easier for the filter components to slide smoothly into or out of the ventilation duct along the guide rod, which is suitable for quick on-site installation and maintenance.

[0012] Preferably, the sealing plate has three sliding grooves on its end face inside the ventilation duct, and each of the three sliding grooves has an insertion hole on its upper wall; the lower ends of the No. 1 filter screen, the No. 2 filter screen and the activated carbon adsorption screen are all integrally formed with sliding strips that slide and connect with the sliding grooves, and the sliding strips are fixedly connected with insertion rods that engage with the insertion holes.

[0013] By adopting the above technical solution, a modular quick-installation connection between the filter screen and the sealing plate is achieved. Through the insertion of a sliding strip into the groove and the engagement of the insert rod with the insertion hole, each layer of filter media can be firmly fixed to the sealing plate, preventing it from falling off or shifting during use. Furthermore, this connection method allows for assembly and disassembly without the need for tools, greatly facilitating the regular cleaning and replacement of the filter media and reducing maintenance difficulty and costs.

[0014] Preferably, the fan assembly includes a mounting plate, which is detachably installed to the ventilation duct via four No. 1 connectors. A frame is fixedly installed on the end face of the mounting plate inside the ventilation duct, and a fan is fixedly installed in the middle of the frame.

[0015] By adopting the above technical solution: the fan assembly adopts an integrated structural design, with the mounting plate serving as the load-bearing platform for the fan system, and a secure connection to the ventilation duct is achieved through the No. 1 connector. The fan is fixed by the frame, resulting in low vibration and low noise during operation, effectively improving ventilation efficiency. In addition, the overall detachable structure facilitates daily maintenance, cleaning, or replacement of motor components, ensuring long-term stable operation of the system.

[0016] Preferably, the first connecting component includes a positioning rod fixedly installed with the ventilation pipe, and a clamping nut threadedly connected to the positioning rod.

[0017] By adopting the above technical solution, a stable mechanical fixing method is provided. The positioning rod is used to accurately define the installation position of the fan assembly, while the clamping nut applies pressure by tightening the thread to ensure that the mounting plate is firmly attached to the end face of the ventilation pipe. This method has the advantages of simple structure, quick installation and strong connection. At the same time, it is easy to disassemble and maintain later, and is suitable for aquaculture environments with frequent maintenance needs.

[0018] Preferably, the mounting plate has mounting holes at each of its four corners that correspond to the positions of the positioning rods and are of the same size. The mounting holes are fitted onto the positioning rods and the mounting plate is fixedly installed on one side of the ventilation pipe by tightening with a clamping nut. The mounting plate has a number of ventilation holes that communicate with the inside of the ventilation pipe.

[0019] By adopting the above technical solutions, the structural design ensures the stability of the fan assembly installation while also taking into account the air circulation requirements. The precise matching of the mounting holes and positioning rods improves the installation accuracy, and the tightening nut further enhances the connection reliability. Meanwhile, the evenly distributed ventilation holes effectively increase the air intake area, reduce wind resistance, improve air intake efficiency, ensure efficient and stable operation of the fan, and improve the overall ventilation performance.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By installing multi-stage filtration components in the ventilation ducts, including a primary filter, a secondary filter, and an activated carbon adsorption screen, the air entering the barn can be efficiently purified. The primary filter intercepts large dust particles, the secondary filter further removes fine suspended matter, and the activated carbon adsorption screen effectively adsorbs harmful gases such as ammonia and hydrogen sulfide, as well as odor molecules, thereby significantly improving the air quality inside the barn. This multi-layer filtration mechanism not only effectively reduces the concentration of pollutants in the air but also reduces the risk of respiratory diseases in livestock caused by inhaling polluted air, helping to improve livestock immunity and growth performance, and thus enhancing breeding efficiency.

[0022] 2. The structural design of this device fully considers the convenience of later maintenance and replacement. All key components adopt modular and detachable connection methods. For example, the filter assembly slides with the mounting bracket and guide rod and is fixed by clamping bolts, allowing the entire filter assembly to be quickly disassembled and assembled, facilitating regular cleaning or replacement of filter media. Simultaneously, each layer of filter screen is secured to the sealing plate via sliding strips and insert rods, allowing for individual replacement of damaged or saturated filter screens without the need for complete replacement. The fan assembly also achieves quick disassembly and assembly via positioning rods and clamping nuts, facilitating fan maintenance or motor component replacement. This flexible structural design not only reduces equipment downtime and improves system continuity but also avoids the problem of traditional equipment being scrapped due to partial damage, significantly reducing maintenance and replacement costs, extending equipment lifespan, and demonstrating good economic viability and promotional value.

[0035] Through the above scheme: after air enters the ventilation duct 1, it first flows through the filter assembly 5 installed inside the ventilation duct. The filter assembly 5 includes a sealing plate 51, a first filter screen 53, a second filter screen 54, and an activated carbon adsorption screen 55. They sequentially perform multi-stage purification treatment on the air. Specifically, the first filter screen 53 is used to intercept large particulate impurities in the air; the second filter screen 54 further removes fine suspended particles in the air; and the activated carbon adsorption screen 55 is used to adsorb harmful gases and odor molecules in the air, improving air quality. After being filtered layer by layer, the air continues to flow forward and finally flows out from the end of the ventilation duct 1 near the inside of the breeding house. It is then evenly delivered into the breeding house through the fixedly connected fan hood 4, achieving a good ventilation effect. In addition, the filter assembly 5 is slidably connected to the guide rod 81 via the U-shaped mounting brackets 52 at both ends. By tightening or loosening the clamping bolts 82, the entire filter assembly 5 can be quickly installed or removed, facilitating daily maintenance and cleaning.

[0036] In this embodiment, the fan assembly 6 includes a mounting plate 61, which is detachably installed on the ventilation pipe 1 via four No. 1 connectors 7.
