Description

Technical Field

[0001] The present invention relates to the technical field of livestock excrement treatment, and in particular to a excrement treatment device for livestock and poultry breeding. Background Art

[0002] Livestock and poultry manure treatment is a key component of environmental protection and resource recycling in the livestock industry, encompassing five main approaches: physical treatment, biological treatment, chemical treatment, energy utilization, and resource utilization. Currently, in practice, manure is typically separated into solid and liquid forms using a dry-wet separator. The solid portion is used for composting, while the separated manure liquid is directly introduced into subsequent sewage treatment systems for continuous purification until it meets discharge standards.

[0003] However, existing dry-wet separators mostly use mechanical extrusion combined with filter interception for separation. Although this method can effectively remove most solid matter, there are still many fine particles and suspended matter remaining in the separated manure water. When a large amount of manure water enters the subsequent treatment system, the impact of the water flow can easily produce a large amount of foam. These foams float on the water surface, covering and blocking the further collection and treatment of light solid residues, seriously affecting the removal efficiency of residual impurities in the manure water. In addition, the accumulation of foam will also reduce the working efficiency of subsequent treatment equipment, increase the difficulty and cost of operation and maintenance, and thus affect the stability and sustainability of the overall manure treatment system.

[0004] Therefore, in response to the above problems, there is an urgent need to develop a manure treatment device for livestock and poultry farming that can effectively remove suspended matter and fine particle impurities in manure, optimize the manure pretreatment process, and improve the overall efficiency of sewage treatment.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0031] Example: A manure treatment device for livestock and poultry breeding, such as Figure 1-Figure 5 Shown, including:

[0032] Bracket 1, serving as the basic supporting structure of the entire livestock and poultry manure treatment device to provide a stable installation platform;

[0033] The screw extruder 2 is fixedly mounted on the bracket 1. The discharge port of the screw extruder 2 is located at the left end, and the feed port of the screw extruder 2 is connected to the feed hopper 21. The screw extruder 2 squeezes the incoming fecal sewage by means of spiral propulsion, thereby effectively separating the solid matter (feces) and liquid (feces water) in the fecal sewage. This is a prior art and will not be described in detail.

[0034] The support cylinder 3 is fixedly arranged between the left and right inner sides of the bracket 1. The support cylinder 3 is a structure with a hollow interior and through-holes at both ends. A processing cylinder 31 is rotatably arranged in the support cylinder 3. The processing cylinder 31 fits tightly against the inner wall of the support cylinder 3 to ensure the sealing between the two. Three transfer chambers 32 are spaced apart circumferentially on the processing cylinder 31. The transfer chamber 32 is used to collect the liquid part separated from the screw extruder 2, allowing the feces and water to settle in a relatively closed space, so that the heavier particles naturally settle to the bottom, while the lighter suspended matter can be removed by the subsequent froth removal component. A driving motor 33 is fixedly installed on the bracket 1, and the output end is connected to the axial end of the processing cylinder 31. The rotation of the processing cylinder 31 is controlled by the driving motor 33, so that the rotation use of multiple transfer chambers 32 can be realized, thereby realizing a continuous feces and water treatment process, greatly improving the working efficiency and processing capacity of the equipment;

[0035] The pushing component 4 for reducing the floating foam includes a winch 41 fixedly arranged on the upper part of the support cylinder 3. The number of the winches 41 is two, and the two winches 41 are arranged in a left-right symmetrical layout to achieve synchronous lifting control. A through hole is also opened on the upper part of the support cylinder 3. A floating plate 42 connected to the rope end of the winch 41 slides inside the support cylinder 3. The floating plate 42 is slidably embedded in the interior of the support cylinder 3 through the through hole, and the floating plate 42 is adapted to the opening size of each transfer chamber 32. Driven by the double winches 41, the floating plate 42 can automatically adjust up and down as the manure liquid level in the transfer chamber 32 changes. Thereby, the surface of the manure in the transfer chamber 32 is effectively covered, and contact with the liquid surface is always maintained, which effectively suppresses the fluctuation of the liquid level caused by the impact of the water flow, and improves the stability of the manure treatment process. The floating plate 42 is provided with through grooves symmetrically on the left and right sides, and each through groove is provided with a vertical frame 421, which serves as the installation basis for the subsequent froth collection structure. A telescopic tube 43 is connected between the left and right sides of the floating plate 42 and the bottom of the screw extruder 2. The lower end of the telescopic tube 43 is aligned with the vertical frame 421 on the same side to ensure that the manure flowing through the telescopic tube 43 can enter the transfer chamber 32 through the through groove of the floating plate 42 and the vertical frame 421;

[0036] The defoaming assembly 5 for removing floating foam is arranged in the vertical frames 421 on both sides.

[0037] like Figure 4 and Figure 5 As shown, the defoaming component 5 includes a through frame 51 fixedly arranged in the vertical frames 421 on both sides, and a duct 52 is connected to the through frame 51. In addition, an electric dragon 53 is symmetrically installed in the vertical frame 421. The electric dragon 53 pushes the floating foam generated in the water flow to the through frame 51 through continuous rotation, thereby realizing automatic collection and transfer of the floating foam. The duct 52 can be further connected to an external negative pressure fan or other suction equipment to form a multi-stage floating foam removal mechanism, thereby improving the defoaming efficiency and significantly improving the cleanliness of the manure pretreatment stage.

[0038] It can be seen that the pushing component 4 and the foam removal component 5 work together to build a complete integrated control structure of "liquid level stabilization + foam removal". This structure realizes the reduction, centralized collection and efficient discharge of suspended solids in the manure treatment process through the linkage operation of multiple components such as the winch 41 controlling the lifting and lowering of the floating plate 42 and the electric dragon 53 pushing the foam in a directional manner. The stable liquid level state can provide a good working environment for subsequent processes such as agent addition and sedimentation separation; the efficient foam removal mechanism helps to reduce the interference of suspended impurities on the treatment process, improve the cleanliness and stability of the manure pretreatment stage, and improve the common problems of violent liquid level fluctuations and difficult foam removal in traditional manure treatment equipment, thereby improving the water purification effect and overall treatment efficiency; at the same time, it further guarantees the feasibility of resource utilization of manure and water and standard discharge.

[0039] In summary, this integrated control structure plays a key role in improving the operational stability, degree of automation, and sewage treatment capacity of the entire device. It can effectively remove suspended matter and fine particle impurities in manure, optimize the pretreatment process, and meet the high standards of environmental protection and resource recycling in the modern livestock and poultry farming industry.

[0040] like Figure 4 and Figure 5 As shown, it also includes a circulation ring 44 and a suction pipe 45. The circulation ring 44 is fixedly arranged in the middle of the floating plate 42. The bottom of the circulation ring 44 is in a closed state. A water inlet 441 is opened circumferentially on the circulation ring 44. The height of the water inlet 441 is lower than the floating plate 42, ensuring that the sewage can smoothly enter the circulation ring 44 during the rising process of the liquid level, effectively avoiding the foam layer on the surface of the sewage, and only extracting the relatively clear middle layer of liquid. The bottom end of the circulation ring 44 is connected to the suction pipe 45. After the suction pipe 45 is connected to the external extraction equipment, the pumping operation can be started according to the processing requirements.

[0041] like Figure 6 As shown, it also includes a dosing component 6, which includes a mounting frame 61 arranged inside the two telescopic tubes 43, and a delivery pipe 62 is provided on the mounting frame 61. The end of the delivery pipe 62 passes through the corresponding telescopic tube 43 and is exposed, and a valve 63 is provided at the outer end of the delivery pipe 62. The delivery pipe 62 is located at the end of the telescopic tube 43 and is rotatably provided with a propeller 64. The propeller 64 can rotate under the impact of the flow of manure, thereby achieving uniform dispersion of the agent.

[0042] like Figure 8 As shown, a scraping assembly 7 is also included. The scraping assembly 7 includes multiple groups of winding drums 71 arranged on the supporting drum 3. The two winding drums 71 of each group are respectively located at the left and right ends of the corresponding transfer chamber 32, and a pull rope 72 is wound between the two winding drums 71 of the same group. The pull rope 72 slides through the left and right ends of the processing drum 31 and is exposed at the inner bottom of the corresponding transfer chamber 32. A scraper 73 is connected to one side of the pull rope 72, and the scraper 73 is slidably connected to the other side of the pull rope 72 to realize the reciprocating motion of the scraper 73, and one end of the processing drum 31 is equipped with a driving motor 2 74 adapted to the number of groups of winding drums 71. The output end of the driving motor 2 74 is connected to the corresponding adjacent winding drum 71. Under the driving action of the driving motor 2 74 and the winding drum 71, the pull rope 72 drives the scraper 73 thereon to slide along the bottom of the transfer chamber 32 to scrape up the deposited feces and push it centrally.

[0043] like Figure 7 As shown, it also includes a collecting frame 8, and outlets are opened on both sides of the support cylinder 3. The support cylinder 3 is provided with a collecting frame 8 located below the outlets on both sides of the support cylinder 3, which is used to receive the solid feces scraped off by the scraping component 7, so as to facilitate centralized collection and subsequent resource processing of feces.

[0044] like Figure 7 As shown, an air pump 81 and a nozzle 82 are also included. The support cylinder 3 is further provided with a nozzle 82 located above the outlet on both sides of the support cylinder 3. The nozzle of the nozzle 82 is directed toward the corresponding collection frame 8, and an air pump 81 connected to the nozzle 82 on the same side is also installed on the support cylinder 3. The air pump 81 is connected to the nozzle 82 through a pipeline and is used to spray compressed air into the feces in the collection frame 8. The blown air flow dries the feces, reduces the moisture content, and facilitates the storage and transportation of the feces.

[0045] During operation, after ensuring the device is horizontal, the fecal wastewater to be treated is introduced into the feed hopper 21. The screw extruder 2 is then activated to squeeze and push the wastewater, transporting it from right to left. During this process, the solid feces are gradually dehydrated and formed due to the squeezing, ultimately being discharged from the left end of the screw extruder 2. The separated liquid (i.e., fecal waste) flows downward into the telescopic tubes 43 on both sides of the device.

[0046] Guided by telescopic tubes 43, the manure enters the corresponding transfer chamber 32 below, where it is collected and concentrated within the treatment drum 31. At this point, the winch 41 is activated to release the rope, driving the attached floating plate 42 to slowly descend along the inner wall of the transfer chamber 32, maintaining contact with the manure surface. The design of the floating plate 42 helps to suppress water surface fluctuations and improve the stability of subsequent treatment.

[0047] Since foam is easily generated when water flows through the slots on the floating plate 42 and enters the transfer chamber 32, in order to effectively control the impact of the foam, it is first ensured that the two side pipes 52 are connected to the negative pressure fan, and then the electric dragon 53 is activated to directional transport the foam formed by the impact of the water flow, so that it is concentrated into the corresponding passage frame 51. Subsequently, the negative pressure fan is activated and, through its connection with the two side pipes 52, the wind force is used to suck and transfer the accumulated foam, thereby maintaining the cleanliness of the manure liquid surface.

[0048] In addition, a defoaming agent can be added to the manure water through the dosing assembly 6 to further reduce foam generation. After opening the valve 63, the agent flows into the telescopic tube 43 through the delivery pipe 62. Under the impact of the manure water flow, the propeller 64 is driven by the water pressure to rotate, thereby achieving uniform dispersion of the agent in the manure water and improving the defoaming effect.

[0049] As the feces accumulate, the water level in the transfer chamber 32 gradually rises, and the solid matter within it gradually settles to the bottom due to gravity. When the sediment reaches a certain thickness, the floating plate 42 is raised to prepare for the next operation of the treatment drum 31. Drive motor 1 33 is then activated, rotating the treatment drum 31 within the support drum 3, moving the transfer chamber 32 with accumulated feces to a side outlet position. Simultaneously, the other empty transfer chamber 32 is adjusted directly below the floating plate 42 to receive the next stage of feces treatment.

[0050] Next, the second drive motor 74 is activated, driving the winding drum 71 to rotate. Pulling the pull rope 72 causes the scraper 73 to slide along the bottom of the transfer chamber 32, loosening and removing the deposited feces, causing them to fall into the collection frame 8 provided below. Then, the air pump 81 is turned on, delivering compressed air to the nozzle 82, which blows towards the collection frame 8 loaded with feces to achieve preliminary air drying of the feces.

[0051] Through the cyclic execution of the above process, continuous and efficient treatment of fecal sewage can be achieved, including the entire process of solid-liquid separation, foam control, chemical addition, fecal residue collection and drying, which overall improves the treatment efficiency and degree of automation.

[0052] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
