Structure of the pig house
The pig house is one of the three important components of the “modelâ€. When building a pig house, the unit matching between the pig house, biogas digester and solar greenhouse must be considered in order to achieve effective utilization of logistics and energy flow. At the same time, consideration should also be given to measures such as temperature increase, insulation, and summer cooling in the pig house, so as to be suitable for pig growth and development throughout the year.
The pig house is located on the top of the biogas tank and one end of the solar greenhouse. The construction sequence is to build the biogas digester first, and then build the pig house and solar greenhouse after the pool body reaches the maintenance standard. The construction of the pig house and the solar greenhouse is best carried out at the same time, because the choice, direction, back wall, gable, height and span of the pig house site should be consistent with the solar greenhouse. In addition, supporting facilities such as gables, toilets, railings, overflow sinks, feed inlets, and pig beds should be built in the piggery to ensure normal operation of the biogas digesters, pig breeding, and solar greenhouses.

Inside the gable of masonry
In order to ensure that there is a suitable environment for the production of pigs and vegetables in order to facilitate the regulation of temperature, humidity and harmful gases, and also to facilitate production management, there must be a gable separation between the solar greenhouse and the pig house. When the width of the pig house is constant from north to south, the position of the gable will determine the area of ​​the pig house. It is generally calculated on the basis of 1 square meter per pig, such as the number of pigs raised, the movement to the solar greenhouse when building a gable, but the length of the thing must not be less than 4 meters. The gable base is built of brick or stone and is 24 cm wide, 70 cm high and 12 cm wide at the top.
Length from the north wall to the south shed. The top height should be consistent with the shape of the arched greenhouse in the solar greenhouse. In the inner gable near the north to stay as a gateway to the solar greenhouse. There are two vent holes in the middle of the gable. The orifice is 24 centimeters and 24 centimeters. The bottom of the high hole is 1.6 meters from the ground. The bottom of the low hole is 70 centimeters away from the ground. The high holes are oxygen exchange holes and the low holes are carbon dioxide exchange holes. Because the specific gravity of carbon dioxide is greater than the specific gravity of oxygen, the two holes exchange the carbon dioxide of the pig house with the oxygen of the solar greenhouse. The top of the gable is plastered with cement mortar.
