Description

Technical Field

[0001] This utility model relates to the field of pigsty air inlet technology, and in particular to a pigsty air inlet filter. Background Technology

[0002] Pigsties are agricultural buildings specifically designed for raising and managing pig herds. Depending on the production stage and feeding purpose, they can be divided into various functional areas, including breeding pigsties, gestation pigsties, farrowing pigsties, nursery pigsties, and finishing pigsties. In modern intensive farming models, these pigsties typically employ a fully enclosed building structure, relying on mechanical ventilation systems to maintain environmental parameters. To ensure air quality within the pigsty, the air inlet system needs to be equipped with multi-stage air filters to improve the pigsty environment, reduce the incidence of disease in pigs, and increase farming efficiency. However, existing pigsty air inlets still have problems such as the inability to replace filters without shutting down the system, the inability to effectively deliver air to all locations, and the inability to disinfect the pigsty.

[0003] Therefore, it is essential to invent a filter for the air inlet of a pigsty. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a pigsty air inlet filter, solving the issues that existing pigsty air inlets still cannot replace filter elements without shutting down the machine, cannot effectively deliver gas to various locations, and cannot disinfect the pigsty. A pigsty air inlet filter includes a purification air intake structure, a bearing bracket, a support base, a motor base, a drive motor, and an air distribution structure. The support base is fixedly installed below the bearing bracket and is then fixedly mounted on the ground via the support base. The bearing bracket is mounted on bearings on both sides of the purification air intake structure, and the motor base is fixedly mounted on the ground. The drive motor is fixedly mounted on the top of the motor base. The output shaft of the drive motor is connected to a shaft on one side of the purification air intake structure. The air distribution structure is fixedly installed at the air outlet of the purification air intake structure.

[0005] The purification air intake structure includes a supporting volute, an air intake chamber, an extension chamber, a filter element, and a blocking plate. The air intake chamber is fixedly installed on both sides of the supporting volute, and the extension chamber is fixedly installed on the top of the two sets of air intake chambers. The filter element is filled inside the extension chamber. The blocking plate is slidably installed on the front side of the top of the air intake chamber.

[0006] The gas distribution structure includes a connection port, a gas distribution chamber, a gas transmission pipe, and a gas distribution pipe. The connection port is fixedly installed on the outlet end of the purification air intake structure, and the gas distribution chamber is fixedly installed on the connection port. The gas transmission pipe is fixedly installed on the top of the gas distribution chamber, and the gas distribution pipe is fixedly installed on the gas transmission pipe and extends into the pig house.

[0007] The purification air intake structure is a centrifugal snail fan, and the air intake chamber is divided into two sets, which are mirror-distributed on both sides of the supporting volute. One set of the air intake chamber is closed by a blocking plate and is not put into use. The air intake chamber is closed when the filter element needs to be replaced, at which time the other set of air intake chambers is open. The filter element is a rectangular filter element, and the filter element completely fills the interior of the extended chamber.

[0008] The gas distribution chamber inside the gas distribution structure is connected to the purified air intake structure through a connection port, and the gas transmission pipeline is a hollow pipe. The gas distribution pipeline consists of several pipes. A one-way valve is installed inside the gas distribution pipeline, and a gas compensation pipe is installed on the outside of the gas outlet end of the one-way valve inside the gas distribution pipeline. High-pressure air is input into the gas distribution pipeline through an air pump at one end of the gas compensation pipe inside the pipeline.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The purification air intake structure of this utility model adopts a centrifugal snail fan and a dual-channel switchable design. Two sets of mirror-distributed air intake chambers and a sliding baffle plate enable non-stop maintenance, ensuring uninterrupted ventilation during filter replacement. The internal rectangular filter element completely fills the extension chamber, significantly increasing the filtration area and residence time, effectively removing dust, pathogens, and harmful gases. Combined with a rotating drive motor to optimize airflow distribution and a modular design to simplify maintenance, this structure, in conjunction with the air distribution structure, achieves clean and stable air delivery within the pigsty. This structure significantly improves filtration efficiency and equipment reliability while ensuring continuous ventilation in the farm.

[0011] 2. The gas distribution structure of this utility model achieves airflow pressure stabilization and eddy current elimination through the gas distribution chamber, ensuring that the airflow deviation in each area is <15% through the gas delivery pipeline and the gas distribution pipeline. The gas distribution pipeline inputs disinfectant gas through an air pump at one end of its internal gas compensation pipe, which can dynamically maintain a positive pressure environment and realize the function of disinfectant gas delivery. It supports rapid connection to an ozone generator for sterilization, meets biosafety requirements, and provides a stable, energy-saving, and disease prevention-safe airflow distribution for pig houses.
