Pig breeding method with function of supplementing warm by extracting heat from waste treatment

Abstract

The invention provides a pig breeding method with a function of supplementing warm by extracting heat from waste treatment. The method is characterized in that a pig house is built, a structure with the upper layer being a pig raising fence and the lower layer being a fermentation bed is arranged in the pig house, the pig raising fence arranged on the upper layer is a pig living area, and the fermentation bed is arranged under the pig raising fence; the vertical projection of the pig raising fence completely falls on the fermentation bed, a rod structure with intervals is arranged at the bottom of the pig raising fence and is used for enabling waste on the pig raising fence to fall on the fermentation bed, the pig raising fence is further provided with a surrounding structure surrounding the periphery of the rod structure; a heat extraction and warm supplementation system is further arranged in the pig house; the air inlet of the heat extraction and warm supplementation system is opened in the breeding process, so that external fresh air enters the heat extraction and warm supplementation system and is heated by heat generated by fermentation in the fermentation bed to form hot air, and the hot air is emitted to a pig living area to supply heat and fresh air to pigs.

Description

technical field [0001] The application belongs to the technical field of heat extraction for pig breeding, and specifically relates to a pig breeding method for obtaining heat and replenishing temperature by processing waste. Background technique [0002] my country is a large agricultural country, and the planting and breeding industries are extremely developed, especially in the northern region of my country. The planting and breeding industries have solved the problem of food and work for a large number of people. [0003] However, the winter in northern my country is cold, and the growth of live pigs will be greatly affected under low temperature conditions. Therefore, the heating problem of winter breeding industry is an extremely important issue. At present, my country's aquaculture industry mainly uses electric or coal heaters for heating, which not only consumes a lot of energy, increases the cost of breeding, but also causes environmental pollution to a certain exte...

Problems solved by technology

[0003] However, the winter in northern my country is cold, and the low temperature will greatly affect the growth of pigs. Therefore, the heating problem of winter breeding industry is an extremely important issue.

At present, my country's aquaculture industry mainly uses electric or coal heaters for heating, which will not only consume a lot of energy, increase the cost of breeding, but also cause environmental pollution to a certain extent.
