Description
Technical Field
The invention relates to the technical field of cultivation facilities, in particular to a large-scale pig raising house in the north.
Background
Factors limiting the production of the pig industry can be summarized in two ways, namely genetics and environment. The genetic decision determines the potential for pig growth and development, while the environment determines how much the genetic potential of organisms can be achieved. Under the current good breeding and scientific management conditions, the environmental conditions become the most important links for further mining the production potential of the pig industry, especially under the large macroscopic regulation of the country, the large-scale pig raising is started in northern areas such as northeast, inner mongolia and the like, and the problems of pig house environmental control are particularly prominent.
In northern areas, the winter is severe and long, and the pigsty must be ventilated to ensure a proper environment, namely: ventilation and heat preservation heating of the pigsty are a pair of contradictions which are difficult to reconcile. After the current pigsty uses reliable insulation, approximately eight heating costs are consumed by ventilation. And if the fresh air outside the house directly enters the house, the fresh air cannot be fully preheated and falls on the bodies of pigs, so that the pigs can only generate cold stress. Therefore, how to reduce ventilation consumption and make the ventilation of the pig house unaffected is a current problem of pig raising in the north.
At present, some pig raising enterprises preheat fresh air by using a heater so as to avoid cold air directly connected into a house to generate cold stress on pigs. There are also some northern pig raising enterprises that use the heat of the ground source in the house to recycle and preheat the fresh air outside the house so as to raise the temperature of the fresh air entering the house and reduce the heating cost. The preheated fresh air enters from the front section of the house and is discharged by the fan. The fresh air is directly heated by the heater, and the temperature of the fresh air entering the house can be improved, but the phenomenon of freezing out of the heating plate can occur due to the lower temperature outside the house. The ground source heat in the house is directly utilized to preheat the fresh air, and although the fresh air has a preheating effect, the ground in the house is frozen due to the lower temperature of the air outside the house, and the ground is frozen.

When the average air temperature is below 0 ℃, the first ventilation window 100, the third ventilation window 300, the fourth ventilation window 400 and the under-eave ventilation window 500 are closed, the second ventilation window 200 is opened, the water curtain window 200' is not activated, and the heating device 9 is started.
The axial flow fan 600 is started, the turbid air exhaust fan 10 is started, the axial flow fan 600 extracts part of air in the house, so that the pressure of the air in the house is instantaneously lower than the atmospheric pressure, negative pressure is formed, and fresh air outside the house enters the preheating pipeline from one end of the preheating pipeline 1000 communicated with the atmosphere; the dirty air in the lower layer of the house is discharged after entering the dirty air trench 700 and the external trench 900 through the dirty air inlet by the dirty air exhaust fan 10, and the fresh air in the preheating pipeline 1000 is preheated for the first time because the preheating pipeline 1000 is positioned in the external trench 900 and the dirty air with higher residual temperature passes through the external trench 900; when the fresh air continues to flow to the fresh air trench 800 in the house, the temperature in the underground layer in the house is higher than the outside temperature because the temperature in the house is far higher than the outside temperature, and the fresh air is preheated for the second time by geothermal resources; the fresh air is preheated for the third time by the heating device 9 in the process of flowing upwards after exiting from the fresh air outlet 801 positioned in the middle corridor; the preheated fresh air enters the blast pipe 20 and is then blown evenly and gently into the pig house from the blast port 201. The turbid gas at the lower layer in the house enters the turbid gas trench 700 and the outer trench 900 from the turbid gas inlet and is discharged, and the preheating pipeline 1000 is preheated, so that circulation is formed.
Embodiment 2, see fig. 1-6,10-11, is different from embodiment 1 in that when the average air temperature is in the range of 0 degrees celsius to 10 degrees celsius, the ventilation requirement of the pig house is increased, so that the first ventilation window 100 and the fourth ventilation window 400 are closed, the second ventilation window 200 and the third ventilation window 300 are opened, the under-eave ventilation window 500 is also opened, the water curtain window 200' is not required to be started, but the heating device 9 is opened, and the heating device is a water heating device or a fuel oil or natural gas heating device.
Not only is a portion of fresh air subjected to three-stage preheating as in example 1, but also the fresh air is blown into the interior and exterior of the pig house uniformly and gently from the air supply port 201, and since the under-eave ventilation window 500 is opened, another portion of fresh air is introduced into the triangular space above the ceiling and below the sloping roof, i.e., the attic, from the under-eave ventilation window 500, and the "attic preheating" is performed with respect to the relatively high temperature in the attic, which corresponds to the first preheating, and then flows downward after entering the intermediate corridor from the third ventilation window 300, is preheated again by the heating device 9, and finally enters the air supply pipe 20 together with the fresh air after the previous portion of preheating, and is blown into the pig house uniformly and gently from the air supply port 201. The turbid gas at the lower layer in the house enters the turbid gas trench 700 and the outer trench 900 from the turbid gas inlet and is discharged, and the preheating pipeline 1000 is preheated, so that circulation is formed.
Embodiment 3, see fig. 1-6,12-13, with the difference that when the average air temperature is between 10 degrees celsius and 26 degrees celsius, the pigsty ventilation requirement is further increased, so that the first ventilation window 100 is closed, the second ventilation window 200, the third ventilation window 300, the fourth ventilation window 400 and the under-eave ventilation window 500 are all opened, the water curtain window 200' is not activated, and the heating device 9 is closed.
In addition to the fresh air intake mode of example 2, fresh air enters the middle corridor from the fourth ventilation window 400 and is then blown into the pig house uniformly and gently through the air supply port 201 after being converged with the other two fresh air parts. The turbid gas at the lower layer in the house enters the turbid gas trench 700 and the outer trench 900 from the turbid gas inlet and is discharged, and the preheating pipeline 1000 is preheated, so that circulation is formed.
Example 4, see fig. 1-6,14-15, otherwise identical to example 3, the water curtain 200' is activated when the average air temperature exceeds 26 degrees celsius, all ventilation windows are open except that the second ventilation window 200 is closed, and the heating means 9 is closed. All fresh air after converging enters the first outer corridor 57 and the second outer corridor 68 after being cooled by the water curtain window 200', the fresh air is divided into two parts, one part of the fresh air is uniformly blown into the pig house from the air supply port 201, the other part of the fresh air directly enters the pig house through the first ventilation window 200, the ventilation quantity is maximum at this time, air in the pig house is forcedly exchanged, and turbid air at the lower layer in the pig house enters the turbid air trench 700 and the external trench 900 from the turbid air inlet and is discharged and simultaneously preheated by the preheating pipeline 1000, so that circulation is formed, and the condition that pigs only grow properly is maintained.
