Description

Technical Field

[0001] The present invention relates to the technical field of livestock and poultry breeding equipment, and particularly relates to a chicken manure drying device that utilizes the waste heat of a chicken coop in combination with a heat pump. Background Art

[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 farms. Chicken manure has a high moisture content and a large volume. If not treated in time, it will not only affect the environmental hygiene of the poultry house, but also easily breed germs, pollute the soil and water sources, causing serious ecological and public health problems. Traditional chicken manure treatment methods mainly rely on natural drying, which is greatly affected by the weather, has a long cycle, low efficiency, and is prone to generating odors, and cannot meet the high-efficiency and environmental protection manure treatment requirements of large-scale farms.

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

[0004] For example, a chicken manure drying device that utilizes the waste heat of chicken coop ventilation with the patent number CN113415971A includes a chicken coop and a controller. A heat source conversion mechanism is arranged on the left side of the chicken coop, a drying mechanism is arranged on the left side of the heat source conversion mechanism, a feeding mechanism is arranged above the drying mechanism, and a discharging mechanism is arranged on the left side of the drying mechanism; the present invention can realize drying chicken manure by using the exhaust gas discharged from the chicken coop, and at the same time switch the heat source according to the external environmental factors and the temperature and humidity parameters of the exhaust gas discharged from the chicken coop to dry the chicken manure, so as to make full use of the heat energy; two conveying mechanisms are arranged to make the chicken manure turn during drying, so that the chicken manure is dried more thoroughly. A cleaning mechanism is arranged to clean the conveying mechanism to prevent chicken manure from sticking to the conveying plate, resulting in blockage of the ventilation holes on the conveying plate and affecting drying; an automatic feeding mechanism is arranged to lay the chicken manure on the upper conveying mechanism, and a baffle is arranged to prevent a large amount of gas in the drying equipment from overflowing. Although the above technical solution can realize the drying of chicken manure, due to the high humidity in the chicken coop in summer, directly using the hot air in the chicken coop cannot better dry the chicken manure due to the high humidity. And when the outside air is pumped out of the chicken coop again in winter or when the weather temperature is low, it is easy to cause the temperature in the chicken coop to be too low, affecting the life of chickens. Moreover, the temperature in the chicken coop is low in winter, and the drying of chicken manure cannot be realized.

[0005] Therefore, we provide a chicken manure drying device that utilizes the waste heat of a chicken coop in combination with a heat pump, which can realize the combined drying of chicken manure by using the waste heat in the chicken coop and the heat pump. Summary of the Invention

[0006] The object of the present invention is to overcome the deficiencies in the prior art and provide a chicken manure drying device that utilizes the waste heat of a chicken coop in combination with a heat pump.

[0007] The object of the present invention is achieved as follows: A chicken manure drying device that utilizes the waste heat of a chicken coop in combination with a heat pump includes a chicken coop. A chicken manure drying mechanism is provided on the left side of the chicken coop, and the chicken manure drying mechanism dries the chicken manure. A heat exchanger is provided between the chicken coop and the chicken manure drying mechanism to cool the inside of the chicken coop and heat the inside of the chicken manure drying mechanism, which can kill two birds with one stone and effectively save energy. The heat exchanger includes an external unit mechanism one and an internal unit mechanism. The external unit mechanism one is located inside the chicken coop, and the internal unit mechanism is located inside the chicken manure drying mechanism. The external unit mechanism one and the internal unit mechanism are combined to transfer and exchange heat into the chicken manure drying mechanism. The heat exchanger also includes an external unit mechanism two, and the external unit mechanism two is located on the top of the chicken coop. The external unit mechanism two and the internal unit mechanism are combined to transfer and exchange heat into the chicken manure drying mechanism.

[0008] Furthermore, two transfer pipes one are provided between the external unit mechanism one and the external unit mechanism two. The upper and lower ends of the transfer pipe one are respectively connected to the external unit mechanism two and the external unit mechanism one. A valve two and a valve one are respectively provided at the upper and lower ends of the transfer pipe one. The middle part of the transfer pipe one is connected to two transfer pipes two. The rear ends of the transfer pipes two are connected to the internal unit mechanism, and a valve three is provided on the transfer pipes two.

[0009] Furthermore, a sealing plate is provided on the top of the chicken coop. The sealing plate is made of heat-insulating material. A solar heating mechanism is provided at the upper end of the sealing plate. The solar heating mechanism and the sealing plate cooperate with the top of the chicken coop to form a placement bin. The sealed structure of the placement bin can prevent external cold air from entering the placement bin. A ventilation opening is provided on the top of the chicken coop. The ventilation opening is located inside the placement bin, and the external unit mechanism two is located inside the placement bin. The solar heating mechanism supplies heat to the inside of the placement bin.

[0010] Furthermore, the solar heating mechanism includes a solar water heater. A heat dissipation box is provided at the rear end of the solar water heater. The heat dissipation box and the solar water heater are connected by two water pipes. A valve four is provided on the water pipes. A water pump (heat pump, that is, to circulate the hot water in the solar water heater) is provided on one of the water pipes. The water in the solar water heater and the water in the heat dissipation box are circulated through the water, and the heat dissipation box dissipates the heat in the water into the placement bin.

[0011] When this application is in use, when drying chicken manure in summer, since the temperature inside the chicken coop is relatively high, by connecting the external unit mechanism one and the internal unit mechanism (closing the valve two and opening the valve one and the valve three), the external unit mechanism one absorbs the heat inside the chicken coop, which can accelerate the heat absorption of the external unit mechanism one, and at the same time can reduce the temperature inside the chicken coop. The internal unit mechanism transfers the heat to the drying box.

[0012] When drying chicken manure in winter, since the temperature in the chicken coop is slightly lower, in order to avoid the external unit mechanism affecting the temperature in the chicken coop, the external unit mechanism one is closed, and the external unit mechanism two is connected to the internal unit mechanism. (Close valve one, open valve two and valve three;) The water is heated by the solar water heater, (open valve four) and then the hot water in the water heater is circulated through the radiator by the water pump for heat dissipation, so that the heat dissipation box dissipates the heat in the water into the placement bin. The external unit mechanism two is quickly heated up by the heat in the placement bin; for the heat in the placement bin that cannot be utilized in time, the heat can be transferred into the chicken coop through the ventilation opening to increase the temperature in the chicken coop.

[0013] The internal unit mechanism dissipates heat in the drying box, and there is no technical limitation on the heat dissipation form. The external unit mechanism one, the external unit mechanism two and the internal unit mechanism are all existing technologies, and a technical solution similar to air-conditioning heating can be adopted to transfer heat. And according to needs, the internal unit mechanism can transfer heat by means of external air intake (supplying air from outside the drying box), and the specific structure is not technically limited.

[0014] The hot air moves upward from the bottom in the drying box to gradually heat and dry the chicken manure on the conveying mechanism; the chicken manure is supplied from the feed inlet to the conveying mechanism in the drying box through the feeding mechanism. The feeding mechanism is an existing technology and will not be elaborated technically, as long as it can achieve the functions required by this application; the conveying mechanism is driven by the driving mechanism two to drive the conveying mechanism to rotate, and the conveying mechanisms distributed up and down move in opposite directions respectively (for example, the chicken manure on the top layer moves from right to left, and the chicken manure below moves from left to right, and the chicken manure is moved left and right in turn). When the chicken manure is conveyed on the conveyor belt, ventilation holes are provided on the conveyor plates on the conveyor belt, which is more conducive to the hot air penetration of the chicken manure; (the dilution or viscosity of the chicken manure does not affect the function of the ventilation holes, that is, if the chicken manure is diluted, the chicken manure adheres or falls to the lower conveying mechanism through the ventilation holes, and the drying of the chicken manure can still be achieved, and the amount of the falling chicken manure is small and hardly affects the entire drying process of the chicken manure;) When the chicken manure at the topmost end moves to the left end, the conveyor plate rotates (flips) downward to drop the chicken manure onto the lower conveying mechanism. The chicken manure moves on the lower conveying mechanism and is dried again.

[0015] When the conveyor plate on the uppermost conveyor mechanism rotates to the left end and then moves downward, due to the fitting effect between the limiting plate and the limiting wheel, when the conveyor plate is located below the roller at the left end, the limiting plate is in a horizontal position, thereby realizing the horizontal placement of the conveyor plate. When continuing to drive to the right, the limiting plate is restricted by the second limiting strip to prevent it from rotating. Thus, under the limiting action of the second limiting strip, multiple conveyor plates restricted by the second limiting strip are kept parallel to the conveyor plate. The cleaning roller is driven to rotate by the first driving mechanism. The outer side of the cleaning roller is a convex strip structure, which can realize the rolling cleaning of the outer side of the conveyor plate. At the same time, it can clean the chicken manure in the ventilation holes of some blocked conveyor plates and clean the chicken manure adhering to the outer side of the conveyor plate.

[0016] When the cleaned conveyor plate continues to drive to the right, the conveyor plate is disengaged from the limiting action of the second limiting strip; both ends of the conveyor plate and the limiting plate are provided with inclined surface structures, resulting in unequal weights at the left and right ends of the conveyor plate. Therefore, the conveyor plate rotates around the rotating shaft under the action of its own gravity, and a gap is formed between adjacent conveyor plates, which can facilitate the hot air at the bottom to pass through and increase the ventilation and drying effect of the chicken manure on the upper conveyor plate (or the hot air heating effect on the conveyor plate, which will also increase the drying efficiency of the chicken manure).

[0017] The conveyor plate continues to move to the right, and the upper part of the limiting plate is squeezed by the limiting wheel below (at the middle position) and rotates obliquely to the left. When the conveyor plate is located below the limiting wheel at the lower part (at the middle position), the limiting plate is horizontally placed, and at the same time, the conveyor plate is horizontally placed; when continuing to move to the right, the limiting plate is restricted by the fourth limiting strip to keep parallel to the conveyor belt at the corresponding position; at this time, the conveyor plate restricted by the fourth limiting strip realizes turning over (inside and outside turning over), and then the cleaning roller cleans the inner side of the conveyor plate.

[0018] The conveyor plate continues to move to the right, and the limiting plate is disengaged from the limiting action of the fourth limiting strip. The conveyor plates form a gap under the action of gravity, which is convenient for the hot air to move upward; when the conveyor plate moves to the position of the third limiting strip on the right, the third limiting strip squeezes and restricts the limiting plate, causing the limiting plate to rotate. When the conveyor plate moves to the right, the outer side of the conveyor plate is still on the outside, and at the same time, the conveyor plate is parallel to the conveyor belt at the corresponding position. It is convenient for the roller shaft on the right to drive the lower conveyor plate to rotate upward around the roller. Thus, the conveyor plate follows the entire rotation action function of the conveyor belt.

[0019] When the conveyor belt on the uppermost conveyor mechanism drives the chicken manure to rotate to the left end, the chicken manure falls onto the lower conveyor mechanism. The lower conveyor mechanism drives the chicken manure to move to the right, increasing the formation of chicken manure in the drying box and realizing the continuous drying of the chicken manure. Finally, the chicken manure falls onto the lower discharging mechanism through the lowermost conveyor mechanism and is discharged outside the drying box.

[0020] Beneficial effects:

[0021] 1. Energy efficient utilization: By setting up a heat exchanger to transfer the waste heat in the chicken coop to the chicken manure drying device, the dual purposes of cooling the chicken coop and heating the chicken manure are achieved, significantly improving the energy utilization efficiency and reducing energy consumption.

[0022] 2. Strong adaptability: The device combines the external machine mechanism I, external machine mechanism II and the solar heating system, corresponding to the operation requirements under different environmental temperature conditions in summer and winter respectively, ensuring that the chicken manure drying process can be carried out stably and efficiently in each season.

[0023] 3. High drying efficiency: The multi-layer conveyor structure design enables the chicken manure to be repeatedly flipped and moved on multiple horizontal planes. Combined with the hot air rising from the bottom and the breathable hole conveyor plate, the hot air penetration efficiency is greatly improved, and the drying uniformity and speed are enhanced.

[0024] 4. Intelligent control and cleaning and maintenance: An automatic limit and conveyor plate flipping structure is set up, combined with the automatic cleaning function of the cleaning roller, which can effectively prevent the chicken manure from blocking the breathable holes and ensure the stability and cleanliness of the long-term operation of the equipment.

[0025] 5. Good sealing and environmental protection performance: A sealed storage bin is set at the top to block the entry of external cold air, avoid heat loss at the same time, improve the heat preservation effect and reduce environmental heat pollution.

[0026] Reasonable structure, suitable for promotion: The whole set of device has a compact structure and high functional integration, which is convenient for centralized control and batch promotion, and has good economic and ecological benefits. Brief description of the drawings

[0041] Example 1, as Figures 1-12 shown, the object of the present invention is achieved as follows: A chicken manure drying device using the waste heat of a chicken coop in combination with a heat pump includes a chicken coop 1. A chicken manure drying mechanism is provided on the left side of the chicken coop 1. The chicken manure drying mechanism dries the chicken manure. A heat exchanger is provided between the chicken coop 1 and the chicken manure drying mechanism to cool the inside of the chicken coop 1 and heat the inside of the chicken manure drying mechanism, which can kill two birds with one stone and effectively save energy. The heat exchanger includes an outer machine mechanism one 20 and an inner machine mechanism 18. The outer machine mechanism one 20 is located inside the chicken coop 1, and the inner machine mechanism 18 is located inside the chicken manure drying mechanism. The outer machine mechanism one 20 and the inner machine mechanism 18 are combined to transfer and exchange heat into the chicken manure drying mechanism. The heat exchanger further includes an outer machine mechanism two 19. The outer machine mechanism two 19 is located on the top of the chicken coop 1. The outer machine mechanism two 19 and the inner machine mechanism 18 are combined to transfer and exchange heat into the chicken manure drying mechanism.

[0042] There are two first transfer pipes 16 arranged between the first external machine mechanism 20 and the second external machine mechanism 19. The upper and lower ends of the first transfer pipe 16 are respectively connected to the second external machine mechanism 19 and the first external machine mechanism 20. A second valve 13 and a first valve 15 are respectively arranged at the upper and lower ends of the first transfer pipe 16. Two second transfer pipes 17 are connected to the middle of the first transfer pipe 16. The rear ends of the second transfer pipes 17 are connected to the internal machine mechanism 18. A third valve 14 is arranged on the second transfer pipes 17.

[0043] A sealing plate 5 is arranged on the top of the chicken coop 1. The sealing plate 5 is made of heat-insulating material. A solar heating mechanism is arranged at the upper end of the sealing plate 5. The solar heating mechanism and the sealing plate 5 cooperate with the top of the chicken coop 1 to form a placement bin. The sealed structure of the placement bin can prevent external cold air from entering the placement bin. A ventilation opening 22 is opened on the top of the chicken coop 1. The ventilation opening 22 is located inside the placement bin. The second external machine mechanism 19 is located inside the placement bin. The solar heating mechanism supplies heat to the placement bin.

[0044] The solar heating mechanism includes a solar water heater 4. A heat dissipation box is arranged at the rear end of the solar water heater 4. The heat dissipation box and the solar water heater 4 are connected by two water pipes. A fourth valve is arranged on the water pipes. A water pump is arranged on one of the water pipes. The water in the solar water heater 4 and the water in the heat dissipation box are circulated through the water. The heat dissipation box dissipates the heat in the water into the placement bin.

[0045] The chicken manure drying mechanism includes a drying box 2. A multi-layer transfer mechanism is arranged inside the drying box 2. The external machine mechanism is located at the bottom of the drying box 2. The external machine mechanism heats the gas inside the box. A heat dissipation plate 7 is arranged on the top of the drying box 2. Heat dissipation holes are evenly opened on the heat dissipation plate 7. An inlet is arranged between the upper right part of the drying box 2 and the heat dissipation plate 7. Chicken manure enters the transfer mechanism through the inlet. A discharge mechanism 3 is arranged at the lower part of the drying box 2. The discharge mechanism 3 discharges the dried chicken manure out of the drying box 2. The discharge mechanism 3 is a prior art and can be a conveyor belt 33 structure, etc., as long as it can discharge the dried chicken manure out of the drying box 2. The discharge mechanism 3 penetrates through the lower right part of the box body. A discharge port is opened on the right side of the drying box 2. A curtain 24 is arranged at the discharge port. The discharge mechanism 3 penetrates through the discharge port. The curtain 24 can reduce the overflow of hot air inside the drying box 2 when discharging at the discharge port. The curtain 24 is a flexible and bendable structure and can automatically bend according to the thickness of the chicken manure on the discharge mechanism 3 to avoid excessive opening of the discharge port and causing a large amount of hot air to overflow.

[0046] A plurality of the conveying mechanisms are vertically distributed in the drying oven 2. The conveying mechanism includes a plurality of roller shafts 28 and two conveyor belts 33. The roller shafts 28 are connected by the conveyor belts 33. Roller wheels 29 are fixedly arranged at the front and rear ends of the roller shafts 28 respectively. The conveyor belts 33 are distributed front and rear on the roller wheels 29 on the roller shafts. A plurality of conveying plates 27 are evenly arranged on the two conveyor belts 33. The front and rear ends of the conveying plates 27 are respectively connected to the conveyor belts 33. There is a clearance fit between adjacent conveying plates 27. The conveying plates 27 and the conveyor belts 33 are rotatably connected. A connecting seat 3435 is arranged between the conveying plates 27 and the conveyor belts 33. Rotating shafts are fixedly arranged in the middle of the front and rear ends of the conveying plates 27. The rotating shafts are rotatably connected to the connecting seat 3435.

[0047] A limiting plate 31 is fixedly arranged at the outer end of the rotating shaft. Bevel structures are respectively arranged at the lower part of the right end of the conveying plate 27 and the lower part of the left end of the limiting plate 31. A limiting wheel 30 is fixedly arranged at the outer end of the roller wheel 29. The inner side surface of the limiting plate 31 is attached to the outer side surface of the limiting wheel 30.

[0048] There are three rollers 28. Two rollers 28 are horizontally distributed, and the other roller 28 is located below the other two rollers 28. On both the front and rear sides between the two upper rollers 28, there are first limiting strips 32 which are horizontally distributed, and the lower surface of the first limiting strip fits with the outer surface of the limiting plate 31. On both the front and rear sides between the left roller 28 and the lower roller 28, there are second limiting strips 36 which are parallel to the conveyor belt 33 between the left roller 28 and the lower roller 28. The upper surface of the second limiting strip fits with the outer surface of the limiting plate 31, and the second limiting strip 36 is located near the left roller 28. On both the front and rear sides between the right roller 28 and the lower roller 28, there are third limiting strips 38 which are parallel to the conveyor belt 33 between the right roller 28 and the lower roller 28. The upper surface of the third limiting strip fits with the outer surface of the limiting plate 31, and the third limiting strip 38 is located near the right roller 28. On both the front and rear sides between the right roller 28 and the lower roller 28, there are fourth limiting strips 37 which are parallel to the conveyor belt 33 between the right roller 28 and the lower roller 28. The upper surface of the fourth limiting strip fits with the outer surface of the limiting plate 31, and the fourth limiting strip 37 is located near the lower roller 28. On the inner sides of both ends of the first limiting strip 32, the second limiting strip 36, the third limiting strip 38 and the fourth limiting strip 37, there are inclined surface structures, which can facilitate the limiting and guiding of the limiting plate 31. The first limiting strip 32, the second limiting strip 36, the third limiting strip 38 and the fourth limiting strip 37 are all fixed on the drying oven 2 to avoid structural movement interference. The rollers 28 are all rotatably connected to the drying oven 2; the second driving mechanism 12 drives the upper and lower conveyor mechanisms to rotate, that is, the driving mechanism 12 drives the driving wheel at its output end to rotate, and the driving wheel drives one roller 28 of one conveyor mechanism to rotate; there is a driving gear 26 on the roller 28, and on the side of the drying oven 2, there are rotatable driven gears 10 and a first driven wheel 11 which rotate synchronously. There is a second driven wheel 25 on one roller 28 of the other conveyor mechanism. The driving gear 26 meshes with the driven gear 10, and the first driven wheel 11 drives the second driven wheel 25 to rotate. The connection method between them is not limited technically as long as the driving function can be realized.

[0049] Below both the second limiting strip 36 and the third limiting strip 38, there are cleaning rollers 23. Driving the cleaning rollers 23 to rotate through the first driving mechanism 6 can clean the upper and lower sides of the conveyor plate 27. The rotation mode of the first driving mechanism 6 driving the cleaning rollers 23 is not limited technically as long as the rotation driving of the cleaning rollers 23 can be realized.

[0050] When this application is in use and drying chicken manure in summer, since the temperature in the chicken coop 1 is relatively high, by connecting the external unit mechanism 20 and the internal unit mechanism 18, (closing valve 13 and opening valve 15 and valve 14), the external unit mechanism 20 absorbs the heat in the chicken coop 1, which can accelerate the heat absorption of the external unit mechanism 20 and at the same time reduce the temperature in the chicken coop 1. The internal unit mechanism 18 transfers the heat to the drying box 2;

[0051] When drying chicken manure in winter, since the temperature in the chicken coop 1 is slightly lower, in order to avoid the external unit mechanism affecting the temperature in the chicken coop 1, the external unit mechanism 20 is closed, and the external unit mechanism 19 is connected to the internal unit mechanism 18, (closing valve 15 and opening valve 13 and valve 14;). The water is heated by the solar water heater 4, (opening valve 4), and then the hot water in the water heater is circulated in the radiator 21 by the water pump for heat dissipation, so that the heat dissipation box dissipates the heat in the water into the placement bin. The external unit mechanism 19 is quickly heated up by the heat in the placement bin; for the heat in the placement bin that cannot be utilized in time, the heat can be transferred to the chicken coop 1 through the ventilation opening 22 to increase the temperature in the chicken coop 1.

[0052] The internal unit mechanism 18 dissipates heat in the drying box 2, and the heat dissipation form is not technically restricted. The external unit mechanism 20, the external unit mechanism 19 and the internal unit mechanism 18 are all existing technologies, and a technical solution similar to air-conditioning heating can be adopted to transfer heat. And according to needs, the internal unit mechanism 18 can transfer heat by means of external air intake (supplying air from outside the drying box 2), and the specific structure is not technically restricted.

[0053] The hot air moves upward from the bottom in the drying box 2 to gradually heat and dry the chicken manure on the conveying mechanism; the chicken manure is supplied from the feeding port to the conveying mechanism in the drying box 2 through the feeding mechanism 8. The conveying mechanism is driven by the driving mechanism 12 to drive the conveying mechanism to rotate. The upper and lower conveying mechanisms move in opposite directions respectively (for example, the chicken manure on the top layer moves from right to left, and the chicken manure below moves from left to right, and the chicken manure is moved left and right in turn). When the chicken manure is conveyed on the conveyor belt 33, ventilation holes are provided on the conveyor plate 27 on the conveyor belt 33, which is more conducive to the hot air penetration of the chicken manure; (the dilution or viscosity of the chicken manure does not affect the function of the ventilation holes, that is, if the chicken manure is diluted, the chicken manure adheres or falls to the lower conveying mechanism through the ventilation holes, and the drying of the chicken manure can still be achieved, and the falling chicken manure is in a small amount and hardly affects the entire drying process of the chicken manure;). When the chicken manure at the topmost end moves to the left end, the conveyor plate 27 rotates (flips) to the lower part to drop the chicken manure onto the lower conveying mechanism. The chicken manure moves on the lower conveying mechanism and is dried again.

[0054] When the conveyor plate 27 on the uppermost conveyor mechanism rotates to the left end and then moves downward, due to the fitting action between the limit plate 31 and the limit wheel 30, when the conveyor plate 27 is below the roller 29 at the left end, the limit plate 31 is in a horizontal position, thus realizing the horizontal placement of the conveyor plate 27. When continuing to be driven to the right, the limit plate 31 is restricted by the second limiting strip 36 and prevented from rotating. Thus, under the limiting action of the second limiting strip 36, multiple conveyor plates 27 restricted by the second limiting strip 36 are kept parallel to the conveyor plate 27. The driving mechanism one 6 drives the cleaning roller 23 to rotate. The outer side of the cleaning roller 23 is a convex strip structure, which can realize the rolling cleaning of the outer side of the conveyor plate 27. At the same time, it can clean the chicken manure in the ventilation holes of some blocked conveyor plates 27 and clean the chicken manure adhering to the outer side of the conveyor plate 27.

[0055] When the cleaned conveyor plate 27 continues to be driven to the right, the conveyor plate 27 is disengaged from the limiting action of the second limiting strip 36; inclined surface structures are provided at one ends of both the conveyor plate 27 and the limit plate 31, resulting in unequal weights at the left and right ends of the conveyor plate 27. Therefore, the conveyor plate 27 rotates around the rotating shaft under the action of its own gravity, and a gap is formed between adjacent conveyor plates 27, which can facilitate the hot air at the bottom to pass through and increase the ventilation and drying effect of the chicken manure on the upper conveyor plate (or the hot air heating effect on the conveyor plate 27, which will also increase the drying efficiency of the chicken manure).

[0056] The conveyor plate 27 continues to move to the right, and the upper part of the limit plate 31 is squeezed by the lower (middle position) limit wheel 30 and rotates obliquely to the left. When the conveyor plate 27 is below the lower (middle position) limit wheel 30, the limit plate 31 is horizontally placed, and at the same time, the conveyor plate 27 is horizontally placed; when continuing to move to the right, the limit plate 31 is restricted by the fourth limiting strip 37 and kept parallel to the conveyor belt 33 at the corresponding position; at this time, the conveyor plate 27 restricted by the fourth limiting strip 37 is turned over (the inner and outer surfaces are turned over), and then the inner side of the conveyor plate 27 is cleaned by the cleaning roller 23.

[0057] The conveyor plate 27 continues to move to the right, and the limit plate 31 is disengaged from the limiting action of the fourth limiting strip 37. A gap is formed between the conveyor plates 27 under the action of gravity, facilitating the upward movement of the hot air; when the conveyor plate 27 moves to the position of the third limiting strip 38 on the right, the third limiting strip 38 squeezes and limits the limit plate 31, causing the limit plate 31 to rotate. When the conveyor plate 27 moves to the right, the outer side of the conveyor plate 27 is still on the outside, and at the same time, the conveyor plate 27 is parallel to the conveyor belt 33 at the corresponding position. It is convenient for the roller shaft 28 on the right to drive the lower conveyor plate 27 to rotate upward around the roller 29. Thus, the conveyor plate 27 follows the entire rotation action function of the conveyor belt 33.

[0058] The chicken manure drying device proposed in this application combines the waste heat recovery of the ventilation in chicken coop 1 and heat pump technology, achieving multiple technical effects of high energy efficiency, intelligent operation, automatic cleaning, and four-season adaptability. The specific manifestations are as follows: 1. Efficient heat recovery and recycling: Through the external machine mechanism 20 installed in chicken coop 1, the waste heat inside chicken coop 1 is transported to the internal machine mechanism 18 through a transmission pipeline to heat the chicken manure drying box 2, achieving the dual goals of cooling chicken coop 1 and heating drying box 2. In the high-temperature season, the temperature inside chicken coop 1 is effectively reduced, the living environment of poultry is improved, the dependence of the heat pump system on electric energy is reduced, and the energy utilization efficiency is significantly improved.

[0059] 2. Design of a season-adaptive drying system: The device can automatically switch the heat source path according to the season: in summer, it uses the waste heat of chicken coop 1, and in winter, the water circulation is heated by the solar water heater 4 and sent to the heat dissipation box to form a closed thermal storage bin. Then, the external machine mechanism 2 transfers the heat in the bin to the drying box 2, avoiding directly extracting the heat inside chicken coop 1 in winter, ensuring the stable temperature of the poultry house, and taking into account both the drying efficiency and the welfare of livestock and poultry. The winter (cold days) and summer (hot days) mentioned in this application are set for most weather conditions. In spring and autumn, it can also be switched according to the change of weather temperature; it can be switched according to the above scheme when the weather temperature is high or low to save energy.

[0060] 3. Multi-level dynamic drying structure: The inside of the drying box 2 adopts a multi-layer conveyor structure. The chicken manure falls layer by layer, flips, and the hot air rises from the bottom and penetrates through the ventilation holes on each layer of conveyor belt 33, realizing uniform heating and drying layer by layer, solving the problems of low drying efficiency and easy caking in traditional single-layer drying, and improving the drying uniformity and efficiency.

[0061] 4. Intelligent limit and flipping structure design: Each layer of conveyor plate 27 realizes controllable flipping and gap formation through limit bars and limit wheels 30, automatically adjusts its angle to ensure that the hot air fully penetrates the chicken manure layer, effectively improving the heat exchange efficiency. At the same time, it realizes automatic turning during the movement of the plate body, avoiding the formation of drying dead corners caused by the accumulation of chicken manure.

[0062] 5. Automatic cleaning and anti-blocking structure: A cleaning roller 23 is added below the limit bar, which cooperates with the rolling rib structure to periodically clean the outer wall of the conveyor plate 27, especially having a significant effect on cleaning the ventilation holes, effectively preventing a large number of blockages in the holes, ensuring the long-term efficient operation of the equipment, and reducing the need for manual maintenance.

[0063] 6. High tightness and heat insulation: The top of chicken coop 1 adopts a heat-insulating sealing plate 5 and a closed storage bin structure, with concentrated heat storage and difficult heat dissipation. External cold air cannot enter the drying system, thereby improving the heat utilization rate, reducing energy consumption, and enhancing the energy-saving and environmental protection characteristics of the device.

[0064] 7. Flexible anti-leakage structure design: A flexible and bendable baffle curtain 24 is provided at the discharge port of the second row of the drying oven 2, which can automatically adapt to the thickness of the discharged material, achieving a good air flow blocking effect. While ensuring the smooth discharge of the material, it avoids a large amount of hot air from escaping during the discharging process, improves the heat utilization rate, and reduces the system energy consumption.

[0065] In summary, the present invention not only greatly improves the drying efficiency of chicken manure, but also realizes energy consumption reduction, stable operation of the system, and a drying strategy adaptable to different climate conditions, effectively solving the problems of high energy consumption, low efficiency, and poor environmental adaptability of traditional poultry manure treatment devices, and having significant practical value and promotion prospects.
