Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hot air circulation heating and hot water supply in livestock and poultry farms, especially a hot air circulation heating and hot water supply device for livestock and poultry farms. BACKGROUND

[0002] Livestock and poultry breeding refers to the agricultural production activities of humans through artificial feeding, breeding and management of livestock (such as pigs, cows, sheep, horses, etc.) and poultry (such as chickens, ducks, geese, etc.) to obtain their economic products such as meat, eggs, milk, wool, and skin, or to use them as labor (such as draft animals), fertilizer (manure), and biological energy sources. It is an important part of agriculture, belonging to the primary industry category, and has the functions of economic production, ecological circulation and social service.

[0003] The hot air circulation heating and hot water supply device for livestock and poultry farms is an integrated environmental control and energy utilization system, mainly used to meet the temperature control, air circulation and hot water demand of farms (such as pig houses, chicken houses, cowsheds, etc.) in different seasons (especially in winter). Its core function is to achieve uniform heating of the breeding space through hot air circulation technology, while also considering the supply of hot water for daily use (such as staff cleaning, feed processing, disinfection, etc.), with the characteristics of high efficiency, energy saving, strong controllability, etc. It is a key equipment for ensuring the healthy growth and production efficiency of animals in modern large-scale breeding. The device is usually composed of a hot air circulation heating subsystem and a hot water supply subsystem, and energy can be collaboratively utilized through heat source sharing or waste heat recovery.

[0004] The existing hot air circulation heating and hot water supply device for livestock and poultry farms generally uses a centrifugal fan to deliver hot air into the breeding box. However, the hot air produced by the centrifugal fan enters the breeding house in the form of high-speed jet, following the free jet decay law (axial speed is inversely proportional to the square of the range). Experimental data shows that when the initial wind speed is 8 m / s, the wind speed at 10 meters away drops to below 2.5 m / s, and the heat carrying capacity decreases significantly. At this time, the internal temperature of the breeding box will not be uniform, which may cause the air temperature near the air outlet area to exceed the upper limit of the livestock and poultry comfort zone, leading to a decrease in feed intake, rapid breathing, and even heatstroke.

[0005] The present application aims to provide a hot air circulation heating and hot water supply device for livestock and poultry farms to solve the problems raised in the background art. SUMMARY

In other instances, well-known techniques are not described in detail in order to avoid obscuring the present application.

[0034] Unless the context clearly requires otherwise, throughout the description, the terms "comprise", "comprising", "include", "including", and the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".

[0035] The connection mode can adopt existing modes such as bonding, welding, bolt connection, etc., and the actual needs are for reference.

[0036] Please refer to Figures 1 to 8 As shown in the figure, the present application provides a hot air circulation heating and hot water supply device for livestock and poultry farms, which comprises a breeding box 1, which is used to breed livestock and poultry. The lower end of the breeding box is provided with a collecting box 3. One side of the collecting box 3 is provided with a water purifier 4, which is used to purify the water source passing through the filter screen. The side of the water purifier 4 away from the collecting box 3 is provided with a water tank 5, which is used to store the heatable water source. The water tank 5 is provided with a heater 6, which is used to heat the water source in the water tank 5. The collecting box 3 is provided with a centrifugal fan 13 inside, which is used to convey the hot air in the water tank 5 into the breeding box 1. The centrifugal fan 13 and the water tank 5 are connected through an air inlet pipe 12;

[0047] Working principle: when it is necessary to ensure that the hot air delivered into the breeding box 1 can be uniformly distributed, the centrifugal fan 13 first makes the hot air in the water tank 5 delivered into the breeding box 1 through the air inlet pipe 12.

[0050] When the flusher 8 cleans the breeding box 1, the hydraulic telescopic rod 1701 should be started to make the baffle 1702 connected therewith move downward until the baffle 1702 is completely closed with the support frame 1401. At the same time, the drain plate 1703 can also avoid the accumulation of the washing water stains on the centrifugal fan 13.
