Description

Technical Field

[0001] This invention relates to the field of poultry farming technology, specifically to a poultry and livestock manure purification system. Background Technology

[0002] The poultry and livestock manure purification system is a comprehensive system for treating and purifying manure generated during livestock and poultry farming. Its purpose is to achieve the harmlessness, reduction, and resource utilization of manure, reduce environmental pollution, and create certain economic value. The system consists of a collection and pretreatment module, a sewage treatment module, a resource utilization module, and a control system.

[0003] Because feces are rich in organic matter, nitrogen, phosphorus and other nutrients as well as pathogens, if they are discharged or piled up directly without being dehydrated, the water will carry pollutants into the soil, flow into surface water or groundwater, and cause problems such as eutrophication (e.g., algal blooms), water quality deterioration, and even pollution of drinking water sources. Dehydration treatment can significantly reduce the possibility of pollutants spreading with water and effectively reduce the harm to the surrounding water environment. Therefore, feces must be dehydrated in the sewage treatment module.

[0004] Common dehydration centrifuges mainly rely on high-speed rotating screens to dehydrate feces. However, in practical applications, if the screen hole diameter is small and the feces contain long fibers such as straw bedding or large solid particles, these substances are easily stuck in the screen holes, causing equipment blockage. If the machine is stopped and cleaned, the dehydration efficiency of the feces will be reduced to some extent. Summary of the Invention

[0005] (1) Technical problems solved

[0006] To address the shortcomings of existing technologies, this invention provides a poultry and livestock manure purification system that solves the problem that common dehydration centrifuges are prone to screen blockage when processing manure containing long fibers such as straw bedding or large solid particles, leading to equipment shutdown for cleaning and thus reducing manure dehydration efficiency.

[0007] (2) Technical solution

A sealing groove and a connecting groove matching the sealing plate are opened inside the box. A vent pipe is fixedly connected inside the box. The inside of the sealing groove is connected to the inside of the connecting groove through the vent pipe. Two sealing rings are fixedly connected inside the connecting groove. The top end of the connecting pipe extends into the inside of the connecting groove, and the opening of the connecting pipe is located between the two sealing rings.

[0011] Furthermore, the dewatering assembly includes a screen cylinder fixedly connected to the end face of the connecting rod, a drive toothed ring fixedly sleeved on the outer surface of the screen cylinder, and a feed hood fixedly connected to the top of the screen cylinder;

[0012] The self-cleaning assembly includes a rotating rod rotatably connected to the inside of the housing via a bearing. A driven gear ring is fixedly sleeved on the outer surface of the rotating rod. The surface of the driven gear ring is meshed with the surface of the driving gear ring. Brush bristles are fixedly connected at equal intervals on the outer surface of the rotating rod. The surface of the brush bristles abuts against the surface of the dehydration assembly.

[0013] Furthermore, the interior of the box is provided with a connecting groove and a discharge hole. The interior of the box is connected to the interior of the liquid outlet pipe through the connecting groove. The top of the sealing disc two is sealed and fitted to the inner wall of the discharge hole. The bottom of the box is fixedly connected with a flow guide hood, the diameter of which is larger than the diameter of the discharge hole.

[0014] Furthermore, the interior of the connecting groove is connected to the top of the interior of the sealing cavity through a connecting pipe, and the outer surface of the annular sealing block is slidably connected to the interior of the sealing cavity. Both the retaining ring and the retaining groove are hexagonal.

[0015] Furthermore, the diameter of the annular sealing block is greater than the diagonal length of the retaining ring, and the outer surface of the sliding rod is non-sealed and slidably connected to the inside of the rotating shaft.

[0016] Furthermore, both the first and second sealing discs are conical. A sealing gasket is fixedly connected to the upper surface of the second sealing disc. An annular limiting groove is provided inside the first sealing disc. A rotating ring is rotatably connected inside the annular limiting groove. An annular top plate is fixedly connected to the top of the rotating ring. The annular top plate is rotatably connected to the surface of the first sealing disc through the annular limiting groove. The surface of the annular top plate is attached to the bottom of the mesh cylinder.

[0017] Furthermore, the top diameter of the feed hood is larger than the bottom diameter, and the output end of the feed port is located inside the feed hood.

[0018] Furthermore, the outer surface of the sealing plate is slidably connected to the inside of the sealing groove, and the top of the inside of the sealing groove is in a non-sealed state.

[0019] Furthermore, when the retaining ring is not engaged with the retaining groove, the sliding rod can rotate freely inside the rotating shaft.

[0020] (3) Beneficial effects

[0021] The present invention has the following beneficial effects:

[0022] (1) The poultry and livestock manure purification system achieves automatic cleaning of the dewatering component through the self-cleaning component. When the screen in the dewatering component rotates, the drive gear ring drives the driven gear ring to rotate, which in turn drives the brush to rotate. The brush inserts into the filter holes on the surface of the dewatering component, which can effectively prevent long fibers such as straw bedding or large solid particles from getting stuck in the screen holes and causing equipment blockage. There is no need to stop the machine for cleaning, which improves the manure dewatering efficiency.

[0023] (2) The system achieves automated switching between dehydration and unloading through the cooperation of the drive component and the unloading component. During dehydration, the retaining ring does not engage with the slot, the sliding rod does not rotate, and the sealing disc seals the unloading hole to ensure the smooth progress of the dehydration process. After dehydration, the electric telescopic rod drives the sealing plate to slide, and the high pressure in the sealing groove enters the sealing cavity through the air pipe and connecting pipe, causing the annular sealing block and other components to drive the sealing disc to slide down and open the unloading hole. At the same time, the retaining ring engages with the slot, and the motor drives the sliding rod and other components to rotate, using centrifugal force to throw out the dehydrated feces, thus achieving automatic unloading. The operation is convenient and efficient.

[0024] (3) The system improves the dehydration and unloading effect through the structural design of each component. Both sealing disc one and sealing disc two are conical, which makes it easy for the feces to be thrown out under the action of centrifugal force. The annular top plate is rotatably connected to sealing disc one through an annular limiting groove, which reduces the friction between the screen cylinder and sealing disc one, making the screen cylinder rotate more smoothly. The setting of the guide hood can guide the feces discharged from the unloading hole to fall vertically and collect it, avoiding the feces from scattering. At the same time, its diameter is larger than the diameter of the unloading hole, which can better receive and guide the feces.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0039] Please see Figure 1-10 This invention provides a technical solution: a poultry and livestock manure purification system, including a box 1, a motor 2 fixedly installed on the top of the box 1, a feed inlet 3 opened on the top of the box 1, a liquid outlet pipe 31 fixedly connected to the bottom side of the box 1, an exhaust pipe 4 fixedly connected to the top inside the box 1, a drive assembly 7 installed at the output end of the motor 2, a dehydration assembly 5 installed outside the drive assembly 7, a discharge assembly 6 installed at the connection between the drive assembly 7 and the box 1, and a self-cleaning assembly 8 installed inside the box 1 on the side of the dehydration assembly 5.

[0040] Specifically, the drive assembly 7 includes a rotating shaft 71 fixedly connected to the output end of the motor 2. Connecting rods 72 are fixedly connected at equal intervals on the outer surface of the rotating shaft 71. A sealing cavity 711 is opened inside the rotating shaft 71. A sliding rod 73 is longitudinally slidably connected at the center of the sealing cavity 711. An annular sealing block 712 and a retaining ring 713 are fixedly sleeved on the outer surface of the sliding rod 73. A retaining groove 714 matching the retaining ring 713 is provided at the bottom of the sealing cavity 711. A connecting rod 74 is fixedly connected to the end of the sliding rod 73. A sealing disc 1 75 and a sealing disc 2 76 are fixedly sleeved on the outer surface of the connecting rod 74. A connecting pipe 78 is fixedly connected inside the rotating shaft 71.

[0041] The unloading assembly 6 includes an electric telescopic rod 61 fixedly installed on the top of the housing 1. The output end of the electric telescopic rod 61 is fixedly connected to a sealing plate 62. The inside of the housing 1 is provided with a sealing groove 63 and a connecting groove 65 that match the sealing plate 62. A vent pipe 64 is fixedly connected inside the housing 1. The inside of the sealing groove 63 is connected to the inside of the connecting groove 65 through the vent pipe 64. Two sealing rings 66 are fixedly connected inside the connecting groove 65. The top end of the connecting pipe 78 extends into the inside of the connecting groove 65, and the opening of the connecting pipe 78 is located between the two sealing rings 66.

[0042] In this embodiment, the rotating shaft 71, connecting rod 72 and other structures in the drive assembly can drive the dewatering assembly 5 to rotate, thereby achieving fecal dewatering. The electric telescopic rod 61, sealing plate 62 and other structures in the unloading assembly 6 can control the air pressure in the sealing groove 63, and then control the movement of the sliding rod 73 through the connecting pipe 78 and other structures to achieve the sealing and opening of the unloading hole 102, as well as the engagement and disengagement of the retaining ring 713 and the retaining groove 714, thereby achieving automated switching between dewatering and unloading, which is convenient and efficient to operate.

[0043] Specifically, the dewatering assembly 5 includes a screen cylinder 51 fixedly connected to the end face of the connecting rod 72, a drive toothed ring 52 fixedly sleeved on the outer surface of the screen cylinder 51, and a feed hood 53 fixedly connected to the top of the screen cylinder 51.

[0044] The self-cleaning assembly 8 includes a rotating rod 81 rotatably connected inside the housing 1 via a bearing. A driven gear ring 83 is fixedly sleeved on the outer surface of the rotating rod 81. The surface of the driven gear ring 83 is meshed with the surface of the driving gear ring 52. Brush bristles 82 are fixedly connected at equal intervals on the outer surface of the rotating rod 81. The surface of the brush bristles 82 abuts against the surface of the dehydration assembly 5.

[0045] In this embodiment, the rotation of the screen cylinder 51 in the dewatering component 5 can dewater the feces, and the drive toothed ring 52 meshes with the driven toothed ring 83 in the self-cleaning component 8, driving the rotating rod 81 and the brush 82 to rotate. The brush 82 abuts against the surface of the dewatering component 5 and can be inserted into the filter holes for cleaning, avoiding long fibers such as straw bedding or large solid particles from getting stuck in the screen holes and causing equipment blockage. There is no need to stop the machine for cleaning, thus improving the dewatering efficiency.

[0046] Specifically, the interior of the housing 1 is provided with a connecting groove 101 and a discharge hole 102. The interior of the housing 1 is connected to the interior of the liquid outlet pipe 31 through the connecting groove 101. The top of the sealing disc 76 is sealed and attached to the inner wall of the discharge hole 102. The bottom of the housing 1 is fixedly connected with a flow guide 103, the diameter of which is larger than the diameter of the discharge hole 102.

[0047] In this embodiment, the connecting groove 101 inside the box 1 can guide the water that has been shaken out to the outlet pipe 31 for discharge; the discharge hole 102 is sealed by the sealing plate 76 during dehydration and is opened after dehydration to discharge the dehydrated feces; the guide hood 103 has a larger diameter than the discharge hole 102, which can guide the feces to fall vertically and collect them to avoid scattering.

[0048] Specifically, the interior of the connecting groove 65 is connected to the top of the interior of the sealing cavity 711 through the connecting pipe 78, the outer surface of the annular sealing block 712 is slidably connected to the interior of the sealing cavity 711, and both the retaining ring 713 and the retaining groove 714 are hexagonal.

[0049] In this embodiment, the connecting groove 65 is connected to the sealing cavity 711 through the connecting pipe 78, which can transmit the air pressure in the sealing groove 63 to the sealing cavity 711, pushing the annular sealing block 712 structure to move. The annular sealing block 712 is slidably connected in the sealing cavity 711, which can ensure the stability of air pressure transmission. The retaining ring 713 and the retaining groove 714 are hexagonal. When engaged, the sliding rod 73 can rotate with the rotating shaft 71 to realize centrifugal unloading.

[0050] Specifically, the diameter of the annular sealing block 712 is greater than the diagonal length of the retaining ring 713, and the outer surface of the sliding rod 73 is non-sealed and slidably connected to the inside of the rotating shaft 71.

[0051] In this embodiment, the diameter of the annular sealing block 712 is larger than the diagonal length of the retaining ring 713. Under air pressure, the retaining ring 713 can be moved first to ensure that the retaining ring 713 and the retaining groove 714 are accurately engaged. The sliding rod 73 is non-sealed and slidably connected in the rotating shaft 71, and can rotate freely when the retaining ring 713 is not engaged, ensuring the sealing performance of the sealing disc 76 during dehydration.

[0052] Specifically, both sealing disc 1 75 and sealing disc 2 76 are conical. A sealing gasket is fixedly connected to the upper surface of sealing disc 2 76. An annular limiting groove 751 is opened inside sealing disc 1 75. A rotating ring 752 is rotatably connected inside the annular limiting groove 751. An annular top plate 753 is fixedly connected to the top of the rotating ring 752. The annular top plate 753 is rotatably connected to the surface of sealing disc 1 75 through the annular limiting groove 751. The surface of the annular top plate 753 is attached to the bottom of the mesh cylinder 51.

[0053] In this embodiment, sealing disc 1 75 and sealing disc 2 76 are conical, which facilitates the ejection of feces under centrifugal force. The sealing gasket on sealing disc 2 76 can enhance the sealing performance of discharge hole 102. The annular limiting groove 751, rotating ring 752 and annular top plate 753 in sealing disc 1 75 can make the annular top plate 753 fit against the bottom of the mesh cylinder 51 and rotate, reducing the friction between the mesh cylinder 51 and sealing disc 1 75, and making the mesh cylinder 51 rotate more smoothly.

[0054] Specifically, the top diameter of the feed hood 53 is larger than the bottom diameter, and the output end of the feed inlet 3 is located inside the feed hood 53.

[0055] In this embodiment, the top diameter of the feed hood 53 is larger than the bottom diameter, which can guide the feces smoothly into the mesh cylinder 51. The feed inlet 3 is located inside the feed hood 53, which can ensure that the feces fall accurately into the mesh cylinder 51 and avoid scattering.

[0056] Specifically, the outer surface of the sealing plate 62 is slidably connected to the inside of the sealing groove 63, and the top of the inside of the sealing groove 63 is in a non-sealed state.

[0057] In this embodiment, the sealing plate 62 is slidably connected in the sealing groove 63, which can ensure the stability of the air pressure in the sealing groove 63. The top of the sealing groove 63 is not sealed, which facilitates the transmission of air pressure through the vent pipe 64 and other structures.

[0058] Specifically, when the retaining ring 713 is not engaged with the retaining groove 714, the sliding rod 73 can rotate freely inside the rotating shaft 71.

[0059] In this embodiment, when the retaining ring 713 is not engaged with the retaining groove 714, the sliding rod 73 can rotate freely within the rotating shaft 71, ensuring that the sealing disc 76 is fixedly sealed to the unloading hole 102 during dehydration. When engaged, the sliding rod 73 rotates with the rotating shaft 71, driving the sealing disc 75 and the sealing disc 76 to rotate, and unloading is achieved by using centrifugal force.

[0060] In use, the feces are placed into the mesh cylinder 51 through the feed port 3. The motor 2 is started, and the motor 2 drives the mesh cylinder 51 to rotate through the rotating shaft 71 and the connecting rod 72. Since the retaining ring 713 is not engaged with the retaining groove 714 at this time, the sliding rod 73 will not rotate when the rotating shaft 71 rotates, thus ensuring the sealing performance of the sealing disc 2 76 to the discharge hole 102. When the mesh cylinder 51 rotates, the mesh cylinder 51 drives the annular top plate 753 and the rotating ring 752 to rotate, reducing the friction between the mesh cylinder 51 and the sealing disc 1 75. Through the rotation of the mesh cylinder 51, the water in the feces is thrown out and falls into the bottom of the box 1 and is discharged through the connecting groove 101 and the liquid outlet pipe 31.

[0061] When the screen cylinder 51 rotates, the drive gear ring 52 meshes with the driven gear ring 83, which drives the rotating rod 81 to rotate. The rotating rod 81 drives the brush bristles 82 to rotate and inserts the brush bristles 82 into the filter holes on the surface of the dewatering assembly 5, which can prevent the mesh holes on the surface of the dewatering assembly 5 from becoming clogged.

[0062] After the feces are dehydrated, the electric telescopic rod 61 is activated to slide the sealing plate 62 downwards, pressurizing the inside of the sealing groove 63. The high pressure inside the sealing groove 63 then enters the connecting groove 65 through the vent pipe 64, and then enters the sealing cavity 711 through the connecting pipe 78. This pressure causes the annular sealing block 712, sliding rod 73, and retaining ring 713 to slide downwards. Simultaneously, the sliding rod 73 drives the first sealing disc 75 and the second sealing disc 76 to slide downwards. When the retaining ring 713 slides into the retaining groove 714, the second sealing disc 76 slides down into the guide shroud 103. At this time, the discharge hole 102 is open, and as the first sealing disc 75 slides down, it opens the bottom of the mesh cylinder 51. Turn on the motor 2, which drives the screen cylinder 51 to rotate through the sealing cavity 711 and the connecting rod 72. This causes the dehydrated feces inside the screen cylinder 51 to fall from the bottom of the screen cylinder 51 and land on the surface of the sealing disc 75. When the rotating shaft 71 rotates, it will drive the sliding rod 73, the sealing disc 75 and the sealing disc 76 to rotate through the engagement of the retaining ring 713 and the retaining groove 714. Due to centrifugal force, the feces on the surface of the sealing disc 75 can be thrown out and fall onto the surface of the sealing disc 76 through the discharge hole 102. Then, due to the centrifugal force, the feces are thrown out by the rotation of the sealing disc 76 and finally fall vertically and are collected by the obstruction of the guide shroud 103.
