Chicken house circulating heat supply system

Abstract

The invention belongs to the technical field of livestock and poultry farming and relates to a chicken house circulating heat supply system. The chicken house heat supply system adopts a water heater to substitute for a hot-blast stove for circulating heat supply, a group or a plurality of groups of single circulating floor heating type hot water pipes are arranged below a bottom grating of each layer of coops, single circulating floor heating type hot water inlet pipes are connected with hot-blast stove water circulating water outlet pipes respectively, single circulating floor heating type hot water return pipes are connected with hot-blast stove water circulating water inlet pipes. Each circulating water inlet pipe is provided with a water replenishing port controlled by a combined sectional valve, and a plurality of groups of independent water heating circulating pipelines form the chicken house circulating heat supply system. A thermosensitive probe is arranged at a starting end of each water circulating water outlet pipe and connected with a temperature controller through a data line to form a temperature control system matched with the chicken house circulating heat supply system. The chicken house circulating heat supply system changes conventional hot-blast stove heat supply patterns, saves fire coal by about 60% and is quick in heat supply, balanced in temperature, appropriate in air humidity and low in production cost, so that chicken flocks are normal in growth, high in growing speed and low in disability rate.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding. Background technique [0002] At present, domestic and foreign chicken houses are mostly heated by hot air stoves in cold seasons, and fans are used to send air to the chicken house through the air supply pipe; since the outlets of the air supply pipes in the chicken house are all set on the top of the chicken house, and hot air is lighter than cold air. Air, usually the hot air fills the top and upper part of the chicken house first and then spreads downwards. It is difficult to reach the middle and lower parts of the chicken house. To achieve normal heating in the middle and lower parts of the chicken house, the heat supply must be increased, and the power and fuel of the heater must be increased. The consumption increases the cost of breeding. Because the heating and warm air in the prior art is output from the top of the chicken house, the hot air sinks slowly, the tem...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a chicken house circulation heating system to solve the problem of using a fan to send air to the chicken house through the air supply pipe in the prior art. The heating air is output from the top of the chicken house, and the hot air sinks slowly. The temperature difference between the upper and lower layers of the chicken house is significant, the upper layer of chicken cages is overheated, and the temperature of the lower layer of chicken cages is low, which cannot meet the optimal environmental conditions required for the normal growth and development of poultry, resulting in abnormal development of chicken flocks, slow growth, and high disability rates , poor meat and egg quality, low economic returns, in order to achieve normal heating in the middle and lower parts of the chicken house, it is necessary to increase the heat supply, increase the power of the heater and fuel consumption, and increase the cost of breeding, etc.
