Pig raising house

Abstract

The invention discloses a pig raising house. The pig raising house comprises a shed body used for raising swinery, an air inlet is formed in one end of the shed body, an air outlet is formed in the other end of the shed body, an exhaust fan is arranged at the air outlet, air circulation in the shed body is achieved through the exhaust fan, and a first filtering device is arranged at the air inlet. Air entering the shed body is filtered through the first filtering device, dust, germs and the like in the air are filtered out to guarantee freshness and cleanness of the air in the shed body, reduce the sick probability of swinery and improve the pig breeding quality, a second filtering device is arranged at the air outlet, waste gas exhausted to the outside from the shed body is filtered out through the second filtering device, and the waste gas is prevented from polluting the environment.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a pig house. Background technique [0002] With the development of economy and society, people's demand for pork is also increasing. In order to meet people's large demand for pork, my country's pig breeding industry is developing in the direction of scale and intensification, and a large number of factory pig farms have been built. [0003] In order to ensure the quality of pig breeding, it is necessary to carry out good ventilation on the pig house, but at present, most of the pig breeding adopts the tunnel ventilation mode, that is, the air enters from one end of the pig house, and a fan is installed at the other end to draw out the wind in the house , this ventilation mode has the following disadvantages: 1) The outside air directly enters the pig house, and the dust particles with germs in the air may infect the pigs, causing disease and death of the pigs; 2) The ...

Problems solved by technology

[0003] In order to ensure the quality of pig breeding, it is necessary to carry out good ventilation on the pig house, but at present, most pig breeding adopts the tunnel ventilation mode, that is, the air enters from one end of the pig house, and a fan is installed on the other end to draw out the wind in the house , this ventilation mode has the following disadvantages: 1) The outside air directly enters the pig house, and the dust particles with germs in the air may infect the pigs, causing disease and death of the pigs; 2) The air always flows from the front of the pig house. To the back end of the pig house, only the pigs in the front pen of the pig house can breathe fresh air, and the breathing air quality of the pigs in the back pen is poor, and the growth rate of the pigs is slow; 3) Once the front pigs get sick, the disease will It will spread rapidly and infect the entire pig house in a short time, causing greater economic losses; 4) In the hot summer mode, the purpose of cooling is achieved through large air volume and high wind speed. Due to the high temperature inside and outside the house, the newly entered air reaches the pig The group surface is limited, usually directly drawn away by the terminal fan, resulting in ineffective ventilation; 5) The large ventilation volume requires a large number of fans, high energy consumption, and high operating costs; 6) The exhaust gas in the pig house is directly discharged into the external environment, causing air pollution
