Description

TECHNICAL FIELD

[0001] The utility model relates to livestock and poultry breeding equipment technical field, especially utilize a chicken coop waste heat combined heat pump's chicken manure drying device. BACKGROUND

[0002] With the continuous improvement of the scale and intensification level of the breeding industry, the treatment of poultry house manure has become one of the key factors restricting the sustainable development of the breeding farm. Chicken manure has high moisture content and large volume. If not treated in time, it not only affects the environmental hygiene of the poultry house, but also easily breeds bacteria, pollutes the soil and water sources, and causes serious ecological and public health problems. The traditional chicken manure treatment method is mainly natural airing, which is greatly affected by the weather, has a long cycle, low efficiency, and easily produces odors, and cannot meet the efficient and environmentally friendly manure treatment needs of large-scale breeding farms.

[0003] In recent years, heat pump drying technology has been widely used in agricultural waste treatment due to its advantages of high efficiency, energy saving, and environmental friendliness. However, the direct use of heat pump drying devices in poultry houses often has problems such as high energy consumption, high operating cost, and difficulty in controlling the temperature of the poultry house environment. Therefore, how to efficiently utilize the waste heat resources generated by the poultry house itself, reduce energy consumption, and simultaneously achieve rapid drying of chicken manure and temperature regulation of the poultry house, has become a technical problem that needs to be solved urgently.

[0004] For example, patent number CN113415971A, a chicken manure drying device utilizing poultry house exhaust heat, includes a poultry house, a controller, a heat source conversion mechanism on the left side of the poultry house, a drying mechanism on the left side of the heat source conversion mechanism, a feeding mechanism above the drying mechanism, and a discharge mechanism on the left side of the drying mechanism. The utility model can realize the drying of chicken manure using the exhaust gas from the poultry house, and can switch the heat source according to the environmental factors and the temperature and humidity parameters of the exhaust gas from the poultry house to dry the chicken manure, so as to fully utilize the heat energy. The two conveying mechanisms can make the chicken manure turn over during drying, making the drying of chicken manure more thorough. The cleaning mechanism can clean the conveying mechanism to prevent the chicken manure from sticking to the conveying plate and blocking the air holes on the conveying plate, affecting drying. The automatic feeding mechanism can lay chicken manure on the upper conveying mechanism, and the baffle can prevent the gas in the drying equipment from overflowing. The above technical solution can dry chicken manure, but due to the high humidity in the poultry house in summer, the use of hot air in the poultry house cannot better dry the chicken manure due to the high humidity. In winter or when the temperature is low, the hot air in the poultry house is extracted again, which can easily cause the temperature in the poultry house to be too low to affect the life of the chickens. In winter, the temperature in the poultry house is too low to dry the chicken manure.

[0005] In order to achieve the above purposes, the present application provides a chicken manure drying device using chicken house waste heat combined with heat pump. Content of the utility model

[0006] The present application aims at overcoming the shortcomings of the prior art and provides a chicken manure drying device using chicken house waste heat combined with heat pump.

[0007] The present application is implemented as follows: a chicken manure drying device using chicken house waste heat combined with heat pump, comprising a chicken house, wherein a chicken manure drying mechanism is arranged on the left side of the chicken house, the chicken manure drying mechanism dries chicken manure, a heat exchanger is arranged between the chicken house and the chicken manure drying mechanism, the heat exchanger cools down the inside of the chicken house and heats up the inside of the chicken manure drying mechanism, so that two purposes are achieved at one time; the heat exchanger effectively saves energy; the heat exchanger comprises an outer mechanism one and an inner mechanism; the outer mechanism one is located in the chicken house, the inner mechanism is located in the chicken manure drying mechanism, and the outer mechanism one and the inner mechanism are combined to deliver and exchange heat into the chicken manure drying mechanism; the heat exchanger further comprises an outer mechanism two, the outer mechanism two is located at the top of the chicken house, and the outer mechanism two and the inner mechanism are combined to deliver and exchange heat into the chicken manure drying mechanism.

[0008] Further, two conveying pipes one are arranged between the outer mechanism one and the outer mechanism two, the upper and lower ends of the conveying pipe one are connected with the outer mechanism two and the outer mechanism one respectively, valve two and valve one are arranged at the upper and lower ends of the conveying pipe one respectively, two conveying pipes two are connected to the middle of the conveying pipe one, the rear end of the conveying pipe two is connected with the inner mechanism, and valve three is arranged on the conveying pipe two.

[0009] Further, a sealing plate is arranged at the top of the chicken house, the sealing plate is made of heat insulation material, a solar heat supply mechanism is arranged at the upper end of the sealing plate, the solar heat supply mechanism cooperates with the sealing plate to form a placing bin at the top of the chicken house, the sealing structure of the placing bin can prevent external cold air from entering the placing bin; a ventilation opening is formed at the top of the chicken house, the ventilation opening is located in the placing bin, the outer mechanism two is located in the placing bin, and the solar heat supply mechanism supplies heat into the placing bin.

[0010] Further, the solar heat supply mechanism comprises a solar water heater, a heat dissipation box is arranged at the rear end of the solar water heater, the heat dissipation box is connected with the solar water heater through two water pipes, valve four is arranged on the water pipes, and a water pump (heat pump) is arranged on one of the water pipes to circulate hot water in the solar water heater, the water in the solar water heater and the water in the heat dissipation box are circulated through the water pipes, and the heat dissipation box dissipates heat in the water into the placing bin.

[0011] When the summer season, the chicken manure drying, due to the temperature in the chicken house is higher, through the communication of the outer machine mechanism one and the inner machine mechanism, (close valve two, open valve one and valve three) through the outer machine mechanism one absorbs the heat in the chicken house, can speed up the heat absorption of the outer machine mechanism one, at the same time can reduce the temperature in the chicken house, through the inner machine mechanism to transfer the heat to the drying box;

[0012] When the winter season, the chicken manure drying, due to the temperature in the chicken house is slightly lower, in order to avoid the influence of the outer machine mechanism on the temperature in the chicken house, close the outer machine mechanism one, the outer machine mechanism two and the inner machine mechanism are communicated, (close valve one, open valve two and valve three; ) through the solar water heater to heat the water, (open valve four) and then through the water pump to circulate the hot water in the radiator to realize the heat dissipation of the heat dissipation box to the heat dissipation box. The outer machine mechanism two realizes rapid heating through the heat in the storage bin; the heat in the storage bin which can not be used in time can be transferred to the chicken house through the ventilation port to realize the temperature increase of the chicken house.

[0013] The inner machine mechanism dissipates heat in the drying box, and the heat dissipation is not technically limited. The outer machine mechanism one, the outer machine mechanism two and the inner machine mechanism are prior art, which can adopt a similar air conditioning heating technical scheme to transfer heat. And according to the need, the inner machine mechanism can realize the transfer of heat by external air inlet (supply air from the outside of the drying box). The specific structure is not technically limited.

[0014] The hot air moves upward in the drying box, and the chicken manure on the conveying mechanism is gradually heated and dried. The feeding mechanism supplies the chicken manure from the feeding port to the conveying mechanism in the drying box, and the conveying mechanism drives the conveying mechanism to rotate. The upper and lower conveying mechanisms move oppositely (for example, the uppermost chicken manure moves from the right side to the left side, the lower chicken manure moves from the left side to the right side, and the chicken manure moves left and right in turn), and the hot air in the drying box dries the chicken manure on the conveying belt.

[0015] When the conveying belt on the uppermost conveying mechanism drives the chicken manure to rotate to the left end, the chicken manure falls onto the lower conveying mechanism, which drives the chicken manure to move to the right, increasing the formation of chicken manure in the drying box and realizing continuous drying of chicken manure. Finally, the chicken manure falls into the lower discharging mechanism through the lowermost conveying mechanism and is discharged out of the drying box.

[0016] Advantages:

[0017] This application utilizes a combined heat pump system with waste heat from the chicken coop to dry chicken manure. This effectively recovers excess heat from inside the chicken coop, allowing for simultaneous cooling and manure drying, significantly improving energy efficiency and reducing energy consumption. By incorporating an outdoor unit and an indoor unit, the system absorbs high-temperature air from inside the chicken coop during summer, accelerating heat transfer to the drying mechanism. This not only effectively dries the manure but also improves the internal environment of the chicken coop. In winter, a solar heating system, in conjunction with the outdoor unit, introduces solar heat into the storage chamber, which is then transferred to the drying chamber by the indoor unit. This simultaneously raises the temperature of the chicken coop, meeting the needs for both insulation and drying in winter.

[0018] By incorporating a switchable multi-valve system, the heat source path can be flexibly switched according to different seasons and needs, demonstrating strong adaptability. The drying mechanism employs a multi-layer conveyor structure and bottom heating, resulting in high drying efficiency and uniform heating of the chicken manure. The overall structural design is rational and multifunctional, significantly reducing reliance on external energy sources in traditional chicken manure drying processes, thus possessing excellent economic benefits and application potential.

A discharging port is arranged on the right side of the drying box 2, a curtain is arranged at the discharging port, the discharging mechanism 3 penetrates the discharging port, and the curtain can reduce the overflow of hot air in the drying box 2 during discharging.
