Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, specifically to a dehydration drying equipment for poultry and livestock manure used in animal husbandry. Background Technology

[0002] In the development of large-scale livestock farming, the resource-based treatment of livestock manure is a crucial link in integrating environmental governance in livestock farming with agricultural ecological development. Livestock includes poultry and livestock, and their manure, after proper treatment, can be applied to farmland on-site. This is an important way to improve soil structure and fertility, and also a high-quality raw material for producing organic fertilizer. Whether the manure is subsequently processed into bagged commercial organic fertilizer or applied directly to arable land, drying is an essential preliminary step. Currently, the mainstream drying method in the industry involves evenly spreading the manure on a mesh conveyor belt and using airflow to remove moisture from the manure, thus completing the drying process.

[0003] However, existing manure dryers have relatively simple functional designs and suffer from numerous technical defects in actual livestock manure treatment, making it difficult to meet the needs of large-scale and efficient processing. Firstly, traditional dryers lack the function of separating wet and dry manure. Wet manure with high moisture content enters the drying process directly without receiving targeted dehydration treatment, which not only significantly reduces the overall manure drying output but also increases the energy consumption of the drying operation. Secondly, during the manure drying process, traditional equipment lacks a suitable turning structure, making it impossible to perform timely and uniform turning operations according to the dryness of the manure. This results in inconsistent drying levels between the surface and inner layers of the manure on the mesh conveyor belt, leading to uneven drying effects. This seriously affects the quality of the manure after subsequent processing into organic fertilizer and reduces its fertilizer efficiency when applied directly, thus restricting the overall efficiency of livestock manure resource utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a dehydration and drying device for poultry and livestock manure in the aquaculture industry, so as to solve the problems in the prior art of poultry and livestock manure drying that cannot prioritize dehydration, have low drying output, and are not turned over during the air drying process, resulting in uneven drying.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dehydration and drying device for poultry and livestock manure used in animal husbandry, comprising a frame, several fans, and a mesh conveyor belt. The fans are installed from left to right on the front of the frame, and the mesh conveyor belt is installed horizontally on the inner side of the frame. The fans provide airflow from front to back to remove moisture from the manure and dry the poultry and livestock manure conveyed by the mesh conveyor belt. A support is installed on the top of the frame, and a sorting mechanism is installed horizontally on the top of the support. A dehumidification mechanism is installed on the left end of the upper surface of the frame, and the sorting mechanism is located directly above the dehumidification mechanism. The sorting mechanism separates the poultry and livestock manure into dry and wet parts, while the dehumidification mechanism compresses and dehydrates the wet manure. A turning mechanism is installed horizontally on the top of the inner side of the frame to turn the manure and ensure that the poultry and livestock manure is dried evenly.

[0006] Preferably, the sorting mechanism includes a material cylinder horizontally mounted on the top of a support. A filter plate is installed on the left end of the lower surface of the material cylinder, and the filter plate filters out wet manure through its own mesh. A hopper is installed on the left end of the top of the material cylinder for storing livestock manure to be processed. A first motor is installed on the left end of the material cylinder, and a screw conveyor is locked to the output end of the first motor through a coupling. Driven by the first motor, the screw conveyor rotates inside the material cylinder, causing the manure to move from left to right. The screw conveyor moves the manure from left to right inside the material cylinder, allowing the manure to pass through the filter plate for dry and wet separation, providing a prerequisite for subsequent targeted dehydration treatment of wet manure.

[0007] Preferably, the dehumidification mechanism includes a compression box installed on the left end of the upper surface of the frame. Two opposing mesh plates are installed on the lower surface of the compression box via pins. The mesh holes of the mesh plates allow water to drain from the feces. A pressure plate is inserted into the inner cavity of the compression box. A protective plate is installed on the rear side of the compression box. A support assembly and a drive assembly are respectively installed on the front and rear sides of the inner cavity of the protective plate. The drive assembly drives the support assembly to move, allowing the pressure plate to move left and right.

[0008] Preferably, the drive assembly includes a second motor installed at the rear end of the right side wall of the guard plate. The output end of the second motor is equipped with a rotating shaft, and the left end of the rotating shaft is installed with the left inner wall of the guard plate through a bearing. A roller and a turntable are respectively installed on the outer wall of the rotating shaft from left to right. The outer wall of the roller is provided with a first sliding groove, and the right side wall of the turntable is provided with a second sliding groove. This serves two purposes: first, to provide intermittent left and right movement power for the support assembly, allowing the pressure plate to compress and dehydrate the manure; and second, to allow the turning mechanism to circulate up and down, turning the manure periodically.

[0009] Preferably, the first groove is elliptical in shape and distributed on the outer wall of the roller, with straight lines at both ends.

[0010] Preferably, the second groove is distributed in a butterfly shape on the right side wall of the turntable, and is divided into an inner arc and an outer arc.

[0011] Preferably, the support assembly includes two guide rods horizontally installed at the front end of the inner cavity of the guard plate. A movable frame is sleeved on the outer wall of the guide rods. The top of the movable frame is installed on the outer wall of the pressure plate. A guide wheel is installed on the rear side of the movable frame and inserted into the inner cavity of the first slide groove. The guide wheel rolls in the first slide groove to reduce the mechanical wear of driving the movable frame to move left and right. A stop bar is horizontally installed at the bottom end of the movable frame.

[0012] Preferably, when the stop bar moves horizontally, it can cause the mesh plate to flip upward.

[0013] Preferably, the turning mechanism includes a slide rail installed on the top of the front and rear inner walls of the frame, a slider slidably connected to the outer wall of the slide rail, a frame horizontally installed on the inner side of the slider, a vertical rod installed on the left rear corner of the upper surface of the frame, a pin installed on the top of the vertical rod to be inserted into the inner cavity of the second slide groove, and multiple rows of plows installed from left to right on the lower surface of the frame; by utilizing the different positions of the plows, the manure is turned over regularly and evenly, so that the manure is dried evenly.

[0014] Preferably, the plow blades are in the shape of an inclined triangle, and the positions of each row of plow blades are staggered.

[0015] The present invention provides a dehydration and drying device for poultry and livestock manure used in animal husbandry, which has the following advantages: 1. This invention uses a first motor to drive the spiral conveyor to rotate, which in turn transports the feces in the material cylinder from left to right. After being filtered by the filter plate, the wet feces fall directionally into the compression box of the dehumidification mechanism, while the dry feces fall directly onto the mesh conveyor belt to enter the air drying stage. This not only achieves effective separation of wet and dry feces, but also optimizes the process connection of feces treatment, provides convenience for targeted dehydration treatment of wet feces, and improves the orderliness of the overall feces treatment process.

[0016] 2. This invention synchronously drives the drum to rotate using a second motor. The first groove on the outer wall of the drum, in conjunction with the guide wheel, drives the moving frame to move intermittently left and right along the guide rod. This, in turn, causes the pressure plate to compress the wet manure in the compression box. The pause at the maximum compression point achieves stable pressure dehydration, effectively increasing the water output of the compressed manure. Simultaneously, the stop bar linked to the moving frame synchronously controls the opening and closing of the screen plate, ensuring precise feeding of the dehydrated manure. After dehydration, the wet manure enters the air-drying stage, significantly increasing the overall drying output of the manure while avoiding energy waste caused by directly air-drying wet manure, thus reducing energy consumption in the air-drying operation.

[0017] 3. This invention relies on the rotation of a turntable driven by a second motor. The height of the frame is changed by the cooperation of the second sliding groove and pin on the turntable, which drives the plow at the bottom of the frame to repeatedly turn the manure on the mesh conveyor belt. This achieves timed and uniform turning of the manure, ensuring that all parts of the manure can fully contact the airflow of the blower, guaranteeing uniform drying of the manure, effectively improving the product quality of the manure after subsequent processing into bagged organic fertilizer, and improving the fertilizer effect when the manure is applied directly on site, further promoting the overall efficiency of the resource utilization of poultry and livestock manure.

[0018] 4. This invention can adjust the compression and dehydration frequency of the pressure plate on the wet manure and the turning frequency of the plow on the manure by simply changing the speed of the second motor according to the actual dry-wet ratio of the poultry and livestock manure to be treated. This allows the equipment to flexibly adapt to the drying and treatment needs of poultry and livestock manure with different dry-wet ratios, meet the manure treatment requirements of different application scenarios such as large-scale farms and organic fertilizer production enterprises, and greatly improve the applicability of the equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8 This invention provides a technical solution: a dehydration and drying device for poultry and livestock manure in the livestock industry, comprising a frame 1, several fans 2, and a mesh conveyor belt 3. The fans 2 are installed from left to right on the front of the frame 1, and the mesh conveyor belt 3 is installed horizontally on the inner side of the frame 1. The fans 2 provide airflow from front to back to remove moisture from the manure and dry the poultry and livestock manure conveyed by the mesh conveyor belt 3. A support 4 is installed on the top of the frame 1, and a sorting mechanism 5 is installed horizontally on the top of the support 4. A dehumidification mechanism 6 is installed on the left end of the upper surface of the frame 1, and the sorting mechanism 5 is located directly above the dehumidification mechanism 6. The sorting mechanism 5 separates the poultry and livestock manure into dry and wet parts, while the dehumidification mechanism 6 compresses and dehydrates the wet manure. A turning mechanism 7 is installed horizontally on the top inner side of the frame 1 to turn the manure and make the poultry and livestock manure dry evenly.

[0023] As a preferred embodiment, the sorting mechanism 5 further includes a material cylinder 51 horizontally mounted on the top of the support 4. A filter plate 52 is installed on the left end of the lower surface of the material cylinder 51. The filter plate 52 filters out wet manure through its own mesh. A hopper 53 is installed on the top left end of the material cylinder 51. The hopper 53 is used to store the poultry and livestock manure to be processed. A valve is provided at the outlet of the hopper 53 to control the amount of manure discharged. A first motor 54 is installed on the left end of the material cylinder 51. The output end of the first motor 54 is locked with a screw conveyor 55 through a coupling. Driven by the first motor 54, the screw conveyor 55 rotates inside the material cylinder 51, allowing the manure to move from left to right, ensuring that the manure is preferentially filtered by the filter plate 52 to achieve the purpose of dry and wet separation. The directional conveying of the screw conveyor 55 ensures that the manure passes fully through the filter plate 52, guaranteeing the orderliness and thoroughness of dry and wet separation, and providing good preconditions for the subsequent targeted dehydration treatment of wet manure.

[0024] As a preferred embodiment, the dehumidification mechanism 6 further includes a compression box 61 installed on the left end of the upper surface of the frame 1. Two opposing mesh plates 62 are installed on the lower surface of the compression box 61 via pins. The mesh of the mesh plates 62 allows water to be discharged from the feces, thus achieving fecal dehydration. A pressure plate 63 is inserted into the inner cavity of the compression box 61. A protective plate 64 is installed on the rear side of the compression box 61. A support assembly 66 and a drive assembly 65 are respectively installed on the front and rear sides of the inner cavity of the protective plate 64. The drive assembly 65 drives the support assembly 66 to run, causing the pressure plate 63 to move left and right. The pressure plate 63 compresses the feces and squeezes out the water from the feces, thus achieving the effect of fecal dehydration.

[0025] As a preferred embodiment, the drive assembly 65 further includes a second motor 651 installed at the rear end of the right side wall of the guard plate 64. A rotating shaft 652 is installed at the output end of the second motor 651, and the left end of the rotating shaft 652 is mounted to the left inner wall of the guard plate 64 via a bearing. A roller 653 and a turntable 654 are respectively installed on the outer wall of the rotating shaft 652 from left to right. Changing the rotation speed of the rotating shaft 652 driven by the second motor 651 controls the frequency of manure dewatering and turning. A first groove 655 is provided on the outer wall of the roller 653. The first groove 655 is elliptical in shape and has straight ends. When the rotation direction of the roller 653 remains unchanged, the first groove 655... If one side of the curved surface presses the guide wheel 663 to the right, the other side of the curved surface will press the guide wheel 663 to the left. When the guide wheel 663 is at the straight end of the first slide groove 655, the guide wheel 663 remains stationary, thereby realizing the intermittent left and right movement of the moving frame 662. The right side wall of the turntable 654 is provided with a second slide groove 656. The second slide groove 656 is distributed in a butterfly shape on the right side wall of the turntable 654, and is divided into an inner arc and an outer arc. When the pin 75 enters the inner arc of the second slide groove 656, the pin 75 rises and stays at the current height. When the pin 75 enters the outer arc of the second slide groove 656, the pin 75 falls and stays at the current height, thereby realizing the lifting and lowering of the frame 73, which serves as the power for the manure circulation and turning. The second motor 651 drives the rotating shaft 652 to coaxially drive the drum 653 and the turntable 654 to rotate. At the same time, it provides power for the compression and dehydration of the dehumidification mechanism and the cyclic turning of the turning mechanism. There is no need to set up a separate power source for the two mechanisms, which reduces the configuration of power components in the equipment, reduces the energy consumption and manufacturing cost of the equipment, and the coaxial drive ensures the synchronization of the two mechanisms. The movable frame 662 enables intermittent left and right movement with pauses, providing pressure stabilization time for the press plate 63 to compress the manure and increasing the dewatering output. The unique design of the second chute 656 of the turntable 654 enables the frame 73 of the turning mechanism 7 to pause after lifting and lowering, allowing the plow shovel 76 to fully contact the manure to complete the turning, avoiding excessive or insufficient turning action and improving the turning effect. By changing the rotation speed of the second motor 651, the compression and dehydration frequency of the pressure plate 63 and the turning frequency of the plow shovel 76 can be adjusted synchronously. This allows for flexible adjustment based on the dry-to-wet ratio and moisture content of the manure to be treated, meeting the treatment needs of different types of poultry and livestock manure and adapting to the diverse treatment scenarios of large-scale farms.

[0026] As a preferred embodiment, the support assembly 66 further includes two guide rods 661 horizontally installed at the front end of the inner cavity of the guard plate 64. A movable frame 662 is sleeved on the outer wall of the guide rods 661, which allows the movable frame 662 to move horizontally left and right. The top of the movable frame 662 is installed on the outer wall of the pressure plate 63. A guide wheel 663 is installed on the rear side of the movable frame 662 and inserted into the inner cavity of the first slide groove 655. The guide wheel 663 rolls in the first slide groove 655 to reduce the mechanical wear of driving the movable frame 662 to move left and right. A stop bar 664 is horizontally installed at the bottom of the movable frame 662. When the stop bar 664 moves horizontally, it can flip the mesh plate 62 upward, allowing the mesh plates 62 on the left and right sides to switch back and forth between opening and closing.

[0027] As a preferred embodiment, the turning mechanism 7 further includes a slide rail 71 installed on the top of the inner wall of the front and rear of the frame 1. A slider 72 is slidably connected to the outer wall of the slide rail 71. The slide rail 71 and the slider 72 cooperate to give the frame 73 the ability to lift. The frame 73 is horizontally installed on the inner side of the slider 72. A vertical rod 74 is installed on the left rear corner of the upper surface of the frame 73. A pin 75 is installed on the top of the vertical rod 74 and is inserted into the inner cavity of the second slide groove 656. The pin 75 is cylindrical. Multiple rows of plows 76 are installed from left to right on the lower surface of the frame 73. The plows 76 are inclined triangles. The inclined surfaces of the plows 76 are used to turn the manure, which has the effect of turning the manure. The positions of each row of plows 76 are staggered, turning the manure at different positions, so that the manure can be dried evenly. The pin 75 adopts a cylindrical structure, which greatly reduces the sliding friction between it and the inner wall of the second slide groove 656, reduces the loss in the power transmission process, improves the power utilization rate, and at the same time reduces component wear and extends the service life of the mechanism; the multi-row plow shovels 76 are staggered, and the turning operation areas complement each other to achieve full coverage of manure and eliminate dead corners in turning.

[0028] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0029] Step 1: Livestock manure falls from hopper 53 into cylinder 51. First motor 54 drives screw conveyor 55 to rotate. Screw conveyor 55 moves the manure from left to right. Wet manure passes through the mesh of filter plate 52 and falls into compression box 61, while dry manure falls onto mesh conveyor belt 3 through the opening on the right side of cylinder 51, thus separating the manure into wet and dry parts. Step 2: The second motor 651 drives the roller 653 and turntable 654 on the rotating shaft 652 to rotate. The first slide groove 655 rotates with the roller 653. The upper and lower sides of the first slide groove 655 are inclined in opposite directions. If one side of the slide groove 655 presses the guide wheel 663 to the right while the rotation direction of the first slide groove 655 remains unchanged, then the other side of the slide groove 655 will press the guide wheel 663 to the left. In addition, the two sides of the first slide groove 655 can limit the guide wheel 663 to stay in the current position. Therefore, the moving frame 662 can move back and forth intermittently. Step 3: When the moving frame 662 drives the pressure plate 63 to move left and right, the stop rod 664 pushes the mesh plate 62 in the compression direction to flip upward, creating a compression space. The pressure plate 63 gradually squeezes the feces. When the pressure plate 63 reaches the maximum compression of the feces, it stabilizes the pressure, allowing excess water in the wet feces to flow down from the mesh plate 62. When the pressure plate 63 switches the compression direction, the stop rod 664 also changes its limiting direction, allowing the mesh plate 62 to flip downward under the gravity of the feces, releasing the feces and dehumidifying the wet feces. Step four: The second chute 656 rotates with the turntable 654. When the pin 75 is in the inner arc position, the upright 74 rises and stops. When the pin 75 is in the outer arc position, it falls and stops. With the cooperation of the slide rail 71 and the slider 72, the frame 73 rises and falls back and forth. When the plow shovel 76 falls, it comes into contact with the manure and turns the manure over, which not only prevents the manure from accumulating, but also allows the manure to dry evenly. Step 5: Adjust the speed of the second motor 651 according to the moisture content of the wet manure, thereby controlling the compression frequency of the wet manure, and adjust the turning frequency of the plow shovel 76 according to the dehumidification efficiency of the wet manure, so as to achieve uniform drying of manure with different moisture contents.
