Dampness removing and fresh air integrated machine system for breeding sheds in cold region

Abstract

The invention relates to a dampness removing and fresh air integrated machine system for breeding sheds in a cold region, and belongs to animal husbandry raising facilities. The dampness removing andfresh air integrated machine system is formed by the assembling of an outdoor self-cooling tank (1), an integrated machine housing (2), a thermal compensation device (3), a wind inlet fan (4), a surface cold dampness removing device (6), a fresh air discharging pipe (8), a connecting hose (10), a wind amount automatic regulation plate (11) and a circulation pump (13). The dampness removing and fresh air integrated machine system disclosed by the invention is especially adapted for breeding sheds in the cold region in north in winter, so that the humidity in the sheds is reduced, the entry of fresh air is increased, the wind exhaust capacity outside the shed is reduced, the heating cost is reduced, and the control of the humidity in the shed of pig sheds in cold region in north in winter isrealized. The dampness removing and fresh air integrated machine system disclosed by the invention has the characteristics of being novel, scientific and reasonable in structure, high in degree of automation and high in applicability.

Description

technical field [0001] The invention mainly relates to a dehumidification and fresh air integrated machine system for breeding houses in cold regions, belonging to the field of animal husbandry facilities. Background technique [0002] In winter, the average outdoor temperature of the breeding houses in the northern cold region is generally more than ten or twenty degrees Celsius below zero. The breeding houses need to be sealed and heated to ensure the normal operation of the breeding process. However, in a relatively closed space, in a large In intensive breeding production, the humidity in the house will be particularly high, which will seriously affect the health and quality of farmed animals. A large amount of ventilation can reduce the humidity in the breeding house and reduce the humidity value in the breeding house, but this requires a large amount of gas exchange. Heat preservation and ventilation are a pair of contradictions. A large amount of ventilation in winter...

Problems solved by technology

[0002] In winter, the average outdoor temperature of the breeding houses in the northern cold region is generally more than ten or twenty degrees Celsius below zero. The breeding houses need to be sealed and heated to ensure the normal operation of the breeding process. However, in a relatively closed space, in a large In intensive breeding production, the humidity in the house will be particularly high, which seriously affects the health and quality of farmed animals

A large amount of ventilation can reduce the humidity in the breeding house and reduce the humidity value in the breeding house, but this requires a large amount of gas exchange. Heat preservation and ventilation are a pair of contradictions. A large amount of ventilation in winter is the key to introducing fresh air outside the breeding house. At the same time, it will seriously reduce the temperature in the breeding house, and more heating equipment is needed to ensure the temperature in the breeding house is stable, which will increase the cost of breeding, otherwise it will not only reduce the temperature in the breeding house, but also increase the humidity in the breeding house due to the intersection of cold and hot air , increase the cold and heat stress effect of farmed animals, which has a very adverse impact on production and breeding. During the large-scale ventilation process, due to the low temperature outside the breeding house, the moisture discharged from the house will quickly freeze at the air outlet to form ice. , affecting the service life of ventilation and ventilation equipment; the existing dehumidification equipment in the house is expensive and consumes a lot of power, which is a considerable investment for farmers
