Description

Technical Field

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

[0002] Pig farming in pens is the most common method of pig farming in modern times. It offers low costs, high standardization, and high yield, making it the choice of most pig farmers. However, this intensive farming method also brings many problems that cannot be ignored. To prevent the rapid spread of viruses caused by air pollution, ventilation facilities are crucial, requiring ventilation devices. Pig pen ventilation structures mainly include natural ventilation and mechanical ventilation, especially mechanical ventilation, which involves air inlets and exhaust outlets. Air inlets include air intake pipes and small roof ventilation windows. In summer, front-end air inlets are often used, while in winter, small roof ventilation windows are more common. The shape, installation location, and adjustment sensitivity of the air inlets affect the uniformity of airflow distribution within the pen. Exhaust outlets are usually created by drilling round holes in the pigpen and installing air guide pipes. Currently, these air guide pipes to the exhaust outlets are typically only fitted with filters, which require disassembly and cleaning over time, making operation inconvenient and difficult to effectively treat odors in the pigpen air.

[0003] Therefore, it is necessary to provide a new pigsty ventilation device to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pigsty ventilation device.

[0005] The pigsty ventilation device provided by this utility model includes an exhaust duct, in which a fixed exhaust fan is built into the front end of the exhaust duct, and a filter assembly and a spring for externally extending the filter assembly are also installed inside the exhaust duct. The filter assembly purifies and filters the odor and dust in the gas inside the pigsty.

[0006] The exhaust duct is equipped with a threaded sealing cap with a threaded connection at the tail end, and an air guide pipe is movably installed on the duct wall near the tail end of the exhaust duct. Multiple sets of air collection components are fixedly installed at the bottom of the air guide pipe.

[0007] The gas collecting device includes an elastic telescopic tube, and side pipes are fixedly installed on both sides of the elastic telescopic tube near the bottom. The elastic telescopic tubes in multiple sets of gas collecting devices are fixedly connected end to end in sequence.

[0008] Preferably, the filtration assembly includes a purification cylinder, on the front end face of which a filter cylinder is coaxially arranged and interconnected, and the diameter of the filter cylinder is smaller than the diameter of the purification cylinder. The purification cylinder contains an activated carbon column, and a filter screen is fixedly installed inside the filter cylinder.

[0009] Preferably, the purification cylinder is fixedly installed with an inner frame away from the cylinder opening of the filter cylinder, and the inner frame is fixedly installed with a filter cloth in the frame cavity.

[0010] Preferably, the activated carbon column is provided with a honeycomb hole with a large aperture.

[0011] Preferably, the exhaust cylinder is fixedly installed with an inner built-in abutting ring, one end of the spring is fixedly connected with the side wall of the inner built-in abutting ring away from the exhaust fan, and the other end of the spring is fixedly installed with a pressing ring.

[0012] Preferably, the inner ring diameter of the pressing ring is greater than the cylinder diameter of the filter cylinder, and the inner ring of the pressing ring is smaller than the cylinder diameter of the purification cylinder.

[0013] Preferably, the threaded sealing cover is threadedly connected with the rear threaded interface of the tail part of the exhaust cylinder, and the inner cover surface of the threaded sealing cover is fixedly installed with an abutting rod for abutting the purification cylinder.

[0014] Preferably, the lower cylinder body of the exhaust cylinder close to the tail part is installed with a connecting spiral pipe in communication with the exhaust cylinder, and the top of the air guide pipe is provided with a screw hole matched with the connecting spiral pipe.

[0015] Preferably, the exhaust cylinder is fixedly sleeved with a fixing frame.

[0016] Compared with the related art, the pig house ventilation device has the following beneficial effects:

[0017] 1. When the filter assembly is replaced, the threaded sealing cover is unscrewed, so that the abutting rod no longer abuts the purification cylinder from the inside, and therefore the purification cylinder is ejected out of the exhaust cylinder under the action of the spring, so that the staff can quickly replace the filter assembly.

[0018] 2. When the exhaust fan is started, the air in the pig house flows into the exhaust cylinder through the side connecting pipes on the air collecting member, and the activated carbon column in the purification cylinder adsorbs the peculiar smell, the air with the peculiar smell is filtered by the filter screen after entering the filter cylinder, and then is discharged out of the pig house through the front cylinder opening of the exhaust cylinder, so that the air pollution in the pig house to the surrounding air environment of the pig house is avoided. Since the elastic expansion pipes can be flexibly stretched or compressed, the side connecting pipes on the side edges of the elastic expansion pipes can be flexibly adjusted, so that the height of the side connecting pipes can be flexibly adjusted according to the needs.
