Constant-temperature water heating device for biogas heat supplying delivery room

Abstract

The invention discloses a constant-temperature water heating device for a biogas heat supplying delivery room. The device comprises an excrement leaking hole, a wall, a supporting mechanism and a heat supplying mechanism, wherein the supporting mechanism comprises four plates, namely, a frame plate, an insulation layer, a heat transfer plate and a floor of the delivery room, wherein the four plates are arranged from top to bottom in a sequence; the excrement leaking hole is formed in the floor of the delivery room; the heat supplying mechanism comprises a coiled pipe, a water bath boiler and a water pump; the water bath boiler and the water pump form a loop through a first water feeding pipe, a second water feeding pipe, the coiled pipe and a water discharging pipe; a tap water pipe is connected to the water discharging pipe; the water bath boiler is connected with a biogas pipe; a temperature control sensor at the bottom part of the water bath boiler is interlocked to an electromagnetic flow rate adjusting valve on the biogas pipe; the water temperature can be adjusted to be within the constant range through the valve. The device is simple in structure and can be fully automatically operated; the indoor temperature can be reasonably adjusted according to the environmental temperature of different seasons and sows; meanwhile, the biogas produced by a breeding farm is fully utilized; the local resources are fully utilized; the national themes of the times of low carbon, energy conservation and environmental protection are met.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a constant temperature water heating device for a biogas heating delivery room. Background technique [0002] Pork is rich in protein, fat, carbohydrates, calcium, phosphorus, iron and other components. Pork is the main non-staple food in daily life. China is the largest producer and consumer of pork in the world, and its pork production has been the first in the world for the past five years. From 2007 to 2012, China's live pig stock accounted for 52% to 60% of the world's total, and the slaughter volume remained at the same level. Between 54% and 56%, the annual inventory in 2011 was 477.115 million heads, and the slaughter volume was 641.25 million heads. The pig breeding areas in China are mainly concentrated in coastal areas along the river, such as the Yangtze River Basin, North China, and southeast coastal areas. [0003] But at present, in the actual feeding of pig raisin...

Problems solved by technology

[0003] But at present, in the actual feeding of pig raising enterprises, the survival rate of pigs is quite low, especially for piglets produced by sows. Because the lives of piglets just born are particularly fragile, large temperature changes can easily cause death of piglets, so sows produce There must be a special delivery room to maintain a constant temperature environment. The well-known heating structure of the delivery room is composed of floor heating and heat preservation lamps. Turn on the floor heating and heat preservation lamps to control the temperature. Floor heating is provided by electricity or coal. When used, it will consume A large amount of electricity or coal does not meet the national low-carbon energy-saving and environmental protection theme of the times, and it cannot achieve the purpose of cooling in hot summer, and at the same time cannot make reasonable use of the biogas produced by the biogas digester in the farm
