Abstract
The utility model discloses a pig house pipeline malleation ventilation unit in winter, the device include PVC pipeline, malleation fan and fine and close cloth cover, connect malleation fan and PVC pipeline with fine and close cloth cover, and malleation fan impresses fresh air PVC pipeline through the cloth cover, realizes giving pig house long distance air supply through the pipeline, and the PVC pipeline other end seals, is equipped with the air outlet on the PVC pipeline, and the air gets into the pig house through the air outlet in the PVC pipeline, and the air outlet prevents that the cold air from directly blowing to the pig on one's body up. The utility model has the advantages that: when the positive pressure fan works, fresh air outside the pigsty is blown into the pipeline, the fresh air in the pipeline enters from the upper part of the pigsty through the hole at the upper part, and exchanges heat with original hot air in the pigsty in the process of slowly descending, so that cold stress to the pigs is avoided when the fresh air reaches the body surface of the pigs.
Description
Technical Field
The utility model belongs to the technical field of the livestock feeding equipment technique and specifically relates to a pig house pipeline malleation ventilation unit in winter.
Background
The fattening pig house has larger span and length, the span is mostly more than 16 meters, the length is more than 50 meters (some are even more than 100 meters), and a trench fan is not considered during construction, so that the existing construction is inconvenient. The pigsty without the negative pressure fan is completely opened by rolling the curtain and the window in summer, and the aim of ventilation and cooling is fulfilled by utilizing natural ventilation. The pigsty provided with the negative pressure fan and the water curtain is opened for a long time in summer by utilizing the fan water curtain, and the purposes of ventilation and cooling are achieved by utilizing longitudinal ventilation. However, in winter, the temperature is low, and most of the roller shutters and the windows need to be sealed to meet the heat preservation requirement. Under the condition, ventilation and air exchange of the pigsty are not enough, a large amount of harmful gas and pathogen remain in the pigsty to cause air pollution, the health of the pigs is not facilitated, the feed conversion rate is reduced, and even more, diseases are caused to cause large loss. The negative pressure fan can solve the problem of ventilation of the pigsty in winter after being started for a long time, but causes excessive temperature loss in the pigsty, and when the fan is started, wind at the position close to the fan and the position close to the air inlet can directly blow on the pig body, so that cold stress of the pig is caused, and the pigsty is not good for health; the negative pressure fan is started for a short time, and the ventilation volume is not enough due to poor tightness and overlong length of the pigsty. The positive pressure fan is used for blowing air to the pigsty in winter, the pig which is close to the end of the fan can be caused to be cold stressed, the temperature difference in the pigsty is large, the effective air distance of the positive pressure fan is short, and the ventilation effect is limited.
Disclosure of Invention
An object of the utility model is to provide a pig house pipeline malleation ventilation unit in winter has solved the not enough problem of pig house ventilation volume in winter. Fresh air is sent into the pigsty through a pipeline by utilizing positive pressure fan blowing, long-distance conveying is realized, fresh cold air enters the pigsty through an air hole in the upper part of the pipeline, the density of the cold air is high, the cold air slowly descends from the upper part of the pigsty, and the temperature is raised by completing heat exchange with hot air in the pigsty in the descending process. The purposes of ventilation and air exchange are realized, and cold stress to swinery is avoided.
The technical scheme of the utility model is that: the utility model provides a pig house pipeline malleation ventilation unit in winter, the device include the PVC pipeline, malleation fan and fine and close cloth cover, connect malleation fan and PVC pipeline with fine and close cloth cover, malleation fan impresses fresh air PVC pipeline through the cloth cover, realize giving pig house long distance air supply through the pipeline, PVC pipeline other end seals, is equipped with the air outlet on the PVC pipeline, the air gets into the pig house through the air outlet in the PVC pipeline, the air outlet prevents that the cold air from directly blowing to the pig on one's body up.
The utility model has the advantages that: when the positive pressure fan works, fresh air outside the pigsty is blown into the pipeline, the fresh air in the pipeline enters from the upper part of the pigsty through the hole at the upper part, and exchanges heat with original hot air in the pigsty in the process of slowly descending, so that cold stress to the pigs is avoided when the fresh air reaches the body surface of the pigs. The fresh air continuously blown in increases the air pressure in the pigsty to promote the foul air in the pigsty to be discharged out of the pigsty. The positive pressure fans with different powers are selected according to the size of the actual space in the pigsty, so that the aim of ventilation and air exchange is fulfilled, and the temperature of the pigsty is not reduced too much, thereby fundamentally solving the contradiction between ventilation and temperature of the pigsty in winter.

Detailed Description
The utility model provides a pigsty pipeline malleation ventilation unit in winter, the device include the PVC pipeline 2 of an upper portion trompil diameter 30cm, pipeline fixing device 7, positive pressure fan 3, fine and close cloth cover 4. Erect the direct 30 cm's of an upper portion trompil PVC pipeline 2 in the overhead 1 of column in the pig house, single pipeline length is no longer than 50 meters, and the pipeline leaves ground 2m-2.5m, fixes PVC pipeline 2 with pipeline fixing device 7, can not let PVC pipeline 2 remove, roll, and 2 one ends of PVC pipeline are blind end 6, and positive pressure fan 3 is connected to 2 one end of PVC pipeline. Positive pressure fan 3 installs outside the pig house or in the wall, and 3 air outlets of positive pressure fan are entangled with fine and close cloth cover 4 and are tied up with the rope, and fine and close cloth cover 4 other one end is connected PVC pipeline 2 and is tied up equally. When the positive pressure fan works, fresh air outside the pigsty is blown into the pipeline, the fresh air in the pipeline enters from the upper part of the pigsty through the hole at the upper part, and exchanges heat with original hot air in the pigsty in the process of slowly descending, so that cold stress to the pigs is avoided when the fresh air reaches the body surface of the pigs.
