Description

Technical Field

[0001] This invention relates to the transfer and pretreatment of manure, specifically to a multifunctional pretreatment and transfer vehicle for manure and a comprehensive treatment and transfer method, belonging to the field of environmental protection and governance technology in the livestock industry. Background Technology

[0002] my country's livestock and poultry industry generates approximately 3.05 billion tons of manure annually. This manure is rich in organic matter and nutrients such as nitrogen and phosphorus, making it a valuable resource that is beneficial when used and harmful when discarded. The "Guiding Opinions on Accelerating the Comprehensive Green Transformation of Agricultural Development and Promoting Rural Ecological Revitalization" issued by the Chinese government requires a significant improvement in the resource utilization level of waste by 2030, explicitly stating that the comprehensive utilization rate of livestock and poultry manure should reach over 85%. The first step affecting the comprehensive utilization rate of livestock and poultry manure is collection and transportation. The level of manure collection and transportation operations not only affects the comprehensive utilization rate and the corresponding resource disposal benefits but also has a significant impact on the environmental sanitation of farms and surrounding areas.

[0003] Large-scale farms in my country mainly consist of pig farms, poultry farms (chickens, ducks, geese, etc.), and cattle and sheep farms. The resulting manure typically includes pig manure, poultry manure, and cattle and sheep manure. Depending on their moisture content, the manure exhibits different states during collection and transportation. Cattle, sheep, and pig manure are generally classified as dry manure or wet manure. Dry manure is a mixture of feces and urine, with a high solid content, low moisture content, and poor fluidity. Wet manure is a mixture of feces, urine, and water, with high moisture content, low viscosity, and some fluidity. Poultry manure is viscous, generally in a semi-solid state, with a moisture content of approximately 85% or less, poor fluidity, high viscosity, and often contains poultry feathers and other substances, making it difficult to directly pump and transport. Therefore, the collection and transportation of manure from farms requires different operating methods for different states of manure, and it is difficult to use the same method to treat manure in different states.

[0004] Currently, livestock farms primarily collect manure using dry cleaning methods, employing manual or mechanical scrapers to move the manure to a centralized storage area outside the sheds. Transportation methods involve manually bagging or loading the manure into trucks for bulk transport, or filling collection pits with water and then using vacuum trucks to siphon it away. To promote rural revitalization and the resource utilization of livestock manure across the county, various regions have established county-level centralized manure resource treatment centers. Third-party organizations regularly collect manure from individual farms and transport it to these centers for centralized treatment.

[0005] However, the aforementioned existing methods of sewage transfer have the following problems:

[0006] 1. If manure is bagged manually or loaded into a wheelbarrow by a manually driven loader and then transported in an open, bulk manner, there are problems such as manure spillage causing environmental pollution, the spread of foul odors affecting the surrounding air, impacting the sanitary environment, and causing the spread of diseases.

[0007] 2. When using a vacuum truck for transportation, if the manure has a high solid content, a moisture content below 85%, and poor flowability (such as dry-cleaned pig manure, cow and sheep manure, or sticky poultry manure containing feathers), the vacuum truck will have difficulty suctioning it and is prone to clogging the pump. In this case, a large amount of water needs to be added to dilute the manure beforehand, usually more than 80% of the manure volume, until the manure moisture content reaches 90% and it has better flowability before the vacuum truck can function effectively. This results in an increased volume of manure, raising transportation costs; it also wastes water resources and increases the workload of subsequent wastewater treatment, leading to higher treatment costs and poor economic efficiency.

[0008] 3. Existing manure transport vehicles generally suffer from drawbacks such as limited functionality, low transport efficiency, narrow applicability, low water resource utilization, and high cost of manure resource treatment.

[0009] A search revealed that Chinese patent "A Transfer Device for Recycling Livestock Farm Manure" (authorization announcement number CN217197892 U, authorization announcement date 2022.08.16) discloses a manure transfer vehicle for loading, crushing, and transporting livestock farm manure to farmland for direct application. The vehicle includes a body, a compartment, an automatic feeding component, and a cutting component. The body is used for transportation, the compartment is used to hold the manure, the automatic feeding component is used to lift the manure on the ground and pour it into the compartment, and the cutting component is used to crush the manure.

[0010] The aforementioned existing technologies are only applicable to fecal waste with low moisture content and are difficult to adapt to watery fecal waste with high moisture content, thus their scope of application is relatively narrow. Secondly, they have limited functions, only able to crush and transport fecal waste without performing other treatments, and cannot make full use of the time to perform more pretreatment of fecal waste during transportation, especially during long transfer distances.

[0011] In summary, the existing sewage transport vehicles have the following shortcomings:

[0012] 1) Narrow scope of application - Existing transport vehicles are either suitable for dry cleaning of pig and poultry manure with low moisture content and poor flowability, or suitable for watery manure with high moisture content and good flowability. They cannot be used for transporting manure with various moisture contents at the same time.

[0013] 2) Single function - Existing transfer vehicles rarely have the function of loading and transporting manure, except for other pretreatment functions. Therefore, they become a low-efficiency link in the process of manure resource utilization.

[0014] 3) High water consumption – When treating sewage with low water content and high solid content, existing suction sewage trucks require a large amount of dilution water to improve the fluidity of the sewage, resulting in a waste of water resources.

[0015] 4) Poor economic efficiency – The low utilization rate of transportation time due to the single function leads to low transfer efficiency; the increased transportation volume and subsequent wastewater treatment workload due to excessive water consumption leads to increased costs of sewage transfer and treatment; therefore, the existing transfer vehicles are very uneconomical. Summary of the Invention

[0016] To overcome the drawbacks of existing manure transportation technologies, this invention proposes a multi-functional pretreatment and transportation vehicle and a comprehensive treatment and transportation method for manure. It integrates multiple functions such as loading, transportation, mixing, pretreatment and cleaning, thereby improving transportation efficiency, conditioning the properties of manure, saving water resources and reducing costs. It achieves the effects of optimized process, convenient operation, wide applicability, energy saving, environmental protection and good economy.

[0017] Based on the above objectives, the technical solution of the present invention is as follows:

[0018] A multi-functional pretreatment transfer vehicle for manure, the manure including poultry manure, and including but not limited to dry-cleaned pig manure, water-fluffed pig manure, and cattle and sheep manure, wherein the moisture content of the poultry manure, dry-cleaned pig manure, and cattle and sheep manure is below 85%, and the moisture content of the water-fluffed pig manure is 85% or above; characterized in that: the pretreatment transfer vehicle integrates multiple functions such as loading, transportation, mixing, pretreatment, and cleaning, and includes:

[0019] The vehicle body is a movable basic carrier used to provide power for loading and transporting sewage;

[0020] The mixing component, fixed to the vehicle body component, is used for loading, mixing and unloading manure, and includes a fully enclosed mixing tank that can rotate around itself, and a variable pump, a metering motor and a reducer that are sequentially driven and connected to the mixing tank.

[0021] The feeding component, retractably mounted on the vehicle body component and connectable to the mixing component, is used to crush, mix, and collect fecal waste and then pump it into the mixing tank. It includes an auger pump, a suction hose, a baffle, and impellers. The auger pump is used to pump fecal waste. One end of the suction hose is connected to the auger pump, and the other end can enter the mixing tank. The baffle is fitted around the suction port at the bottom of the auger pump and can move up and down to switch between mixing and collecting functions. Two impellers are located on the left and right sides of the baffle and rotate in opposite directions to agitate, crush, collect, and mix the fecal waste.

[0022] A dosing component, fixed to the vehicle body and connected to the mixing component, is used to contain fecal matter conditioner and add the conditioner to the mixing tank to complete the pretreatment of fecal matter. It includes a dosing pump, a solenoid valve, a dosing pipe, and a dosing tank. The dosing tank is used to store the conditioner. One end of the dosing pump is connected to the dosing tank, and the other end is connected to the mixing tank through the solenoid valve and the dosing pipe to deliver the conditioner into the mixing tank.

[0023] A water circulation component, fixed to the vehicle body component and connected to the mixing component, is used to add water to the sewage, clean the mixing component, and recycle the cleaning water. It includes a circulation pump, a water supply pipeline, a return pipeline, and a water tank. The water tank is used to store water. The circulation pump is connected to the water tank and is used to provide power for transporting water. One end of the water supply pipeline is connected to the circulation pump, and the other free end can be connected to the mixing tank for injecting water into the mixing tank. One end of the return pipeline is connected to the water tank, and the other end is connected to the inner cavity of the mixing tank for recycling the cleaning water.

[0024] The control system is installed on the vehicle body component and is connected to the stirring component and the dosing component respectively. It has a pretreatment program installed inside to control the automated operation of the stirring component and the dosing component in order to achieve the pretreatment of manure.

[0025] The pretreatment refers to: conditioning the properties of fecal waste by stirring and adding property conditioning drugs, increasing the rate of water separation in fecal waste, destroying the stability of polysaccharides and protein colloidal substances on the surface of fecal waste, releasing interstitial water and bound water, thereby reducing the viscosity of fecal waste, increasing the hydrophobicity of fecal waste, and further improving the flocculation of solid particles therein, so as to improve the solid-liquid separation effect of fecal waste.

[0026] As a further improvement, the control system is connected to the variable pump of the stirring component and the dosing pump and solenoid valve of the dosing component, and signals are transmitted between them. The control system controls the start, stop and speed of the variable pump according to the built-in pretreatment program to control the rotation of the stirring tank, and at the same time controls the operating sequence and duration of the dosing pump and solenoid valve, thereby completing the automatic operation of stirring and dosing during the pretreatment process.

[0027] As a further improvement, the gathering function state of the feeding component refers to: the baffle moves down and its lower edge aligns with the edge of the suction port of the auger pump, so as to block the sewage from staying in the area next to the suction port and guide the sewage to gather towards the suction port. The two counter-rotating impellers collect the sewage towards the suction port, so that the sewage can be directly sucked into the suction port.

[0028] The stirring function of the feeding component refers to the following: the baffle moves up and retracts and moves away from the area around the suction port, making room for the impeller, thereby achieving full stirring of the sewage.

[0029] As a further improvement, the lower end of the impeller is fixedly equipped with blades, which are located at the same horizontal position as the suction port. The blades of the two impellers are installed in opposite directions, and the blades are sickle-shaped with their upper edges tilted outward at an angle.

[0030] As a further improvement, the tilt angle is 60° to ensure that the impeller achieves the best collection and aggregation effect on the sewage.

[0031] As a further improvement, the property-conditioning drug includes quicklime and cationic polyacrylamide solution.

[0032] As a further improvement, the concentration of the cationic polyacrylamide solution is 1-5‰, and the amount of quicklime added is 2-4% of the volume of the fecal matter.

[0033] As a further improvement, the feeding component also includes a traction rod and a limiting plate; the traction rod is arranged along the axial direction of the auger pump, with the lower end fixedly connected to the baffle and the upper end located above the feeding component, for operating the baffle to move up and down above the sewage; the limiting plate is arranged near the upper part of the feeding component, for limiting the upward stroke of the traction rod.

[0034] As a further improvement, the operating time of the dosing pump is determined based on the amount of fecal matter, the concentration of the dosing agent, and the operating frequency of the dosing pump. The value is adjustable and input into the control system. When the operating time of the dosing pump reaches the set value, the dosing component stops operating.

[0035] As a further improvement, the water circulation component also includes an external pipeline, one end of which is connected to the water tank, and the other end is connected to an external water source via an E-type quick connector to replenish water into the water tank. The lower part of the water tank is provided with a sludge removal port for periodically cleaning the sediment in the water tank.

[0036] Another technical solution of the present invention is as follows:

[0037] A comprehensive treatment and transportation method for fecal waste using the aforementioned multi-functional pretreatment transfer vehicle includes the following steps:

[0038] Step 1, Preparation Stage – Based on the morphology of the feces and sewage being transported, determine the pretreatment control parameters and input them into the control system, establish a pretreatment program for conditioning the feces and sewage characteristics, add water to the water tank, and add the corresponding feces and sewage characteristics conditioning drugs to the drug tank of the dosing component.

[0039] Step two, loading stage—Depending on the form of the transported manure, the manure is drawn into the mixing unit using different methods through the feeding component. After completion, the mixing tank is sealed.

[0040] For watery pig manure, place the auger pump into the manure and connect the suction hose to the mixing tank, then start the auger pump to pump the manure into the mixing tank.

[0041] For dry-cleaned pig manure and cow and sheep manure, first move the baffle down so that the lower edge is aligned with the edge of the suction port, adjust the feeding component to the collection function state, then put the auger pump into the manure, and at the same time, connect the suction hose to the mixing tank, then start the impeller to rotate, and then start the auger pump to transport the manure into the mixing tank.

[0042] For poultry manure, firstly, water is added to the manure through the water circulation component. Then, the baffle is moved up and the feeding component is adjusted to the stirring function state. Next, the auger pump is placed into the manure, and the suction hose is connected to the mixing tank. Then, the impeller is started to rotate to stir the manure and water. After stirring for 3 to 5 minutes, the auger pump is started to transport the manure into the mixing tank.

[0043] Step 3, Transfer and Pre-treatment Stage – The transfer vehicle embarks on the transfer route, and at the same time, the control system automatically controls the stirring and dosing components to operate in different programs according to the form of the transferred manure, so as to realize the automated pre-treatment of the transferred manure and complete the conditioning of the manure's properties.

[0044] Step 4, unloading stage—After the transfer vehicle reaches the destination and the pretreatment is completed, the mixing component is opened, and the mixing tank unloads the conditioned manure.

[0045] Step 5, Cleaning Stage – Open the water circulation component, start the circulation pump, and manually operate the water supply pipeline to rinse the inside and outside of the mixing tank, thus completing the cleaning of the mixing component.

[0046] As a further improvement, the automated pretreatment methods for different forms of fecal waste are as follows:

[0047] For watery pig manure, no pretreatment is required;

[0048] For dry-cleaned pig manure and cow and sheep manure, the mixing tank is controlled to rotate to mix the manure;

[0049] For poultry manure, first add quicklime to the mixing tank and control the mixing tank to rotate for 5-10 minutes. Then start the dosing pump and add cationic polyacrylamide solution to the manure in the mixing tank. After the amount of conditioning drug added reaches the predetermined value, turn off the dosing pump. The manure pretreatment is then complete.

[0050] As a further improvement, for dry-cleaned pig manure, the rotation speed of the mixing tank is 0.5-1 r / min; for poultry manure, the rotation speed of the mixing tank is 2-4 r / min, the amount of quicklime added is 2-4% of the manure volume, and the concentration of the cationic polyacrylamide solution is 1-5‰.

[0051] As a further improvement, in step two, the amount of water added is 20-30% of the amount of fecal waste.

[0052] Another technical solution of the present invention is as follows:

[0053] The above-mentioned integrated treatment and transfer method for manure is applied to the transfer of manure of various moisture contents, including but not limited to animal manure such as rabbit and mink manure, and organic solid waste such as kitchen waste treatment tailings and food processing waste.

[0054] Compared with the prior art, the present invention achieves the following beneficial effects:

[0055] (1) Automatic pretreatment of fecal waste was achieved, improving its properties and greatly enhancing the processing efficiency of subsequent solid-liquid separation processes. The transport vehicle is equipped with a stirring component and a dosing component, enabling the conditioning of fecal waste properties through stirring and the addition of chemicals. Stirring increases the rate of water separation in fecal waste through mechanical and centrifugal forces. The high temperature and alkaline environment generated by quicklime in the conditioning agents disrupt the stability of polysaccharides and protein-like colloidal substances on the surface of fecal waste, releasing bound water and interstitial water, thereby reducing the viscosity of fecal waste and improving its hydrophobicity. The cationic polyacrylamide solution (PAM) in the conditioning agents further enhances the flocculation of solid particles. The improvement in fecal waste properties creates favorable conditions for subsequent solid-liquid separation processes, greatly improving the effect of solid-liquid separation, increasing the solid-liquid separation efficiency by 12%, and reducing the water content of fecal waste to 65% after solid-liquid separation, thus promoting the overall efficiency of fecal waste resource utilization.

[0056] (2) High degree of integration, which improves the efficiency of manure transfer operation - The transfer vehicle integrates multiple functions such as loading, transportation, mixing, pretreatment and cleaning. It not only has the usual loading and transportation functions, but also the functions of manure property conditioning and cleaning, which reduces the investment in manure disposal equipment. During the transportation of manure, the pretreatment process is run at the same time, which saves operation time, improves time utilization, and greatly improves the efficiency of transfer operation.

[0057] (3) It is economical, widely applicable, and capable of handling various forms of livestock manure. The feeding component, stirring component, dosing component, and control system of the transfer vehicle can perform different effective operations according to the different forms of manure. The feeding component has multiple functions such as feeding, stirring, and collecting, which can cope with various livestock manure conditions. The control system can be built into pretreatment programs for different forms of manure, thus greatly expanding the diversity of manure types that this invention can handle. This invention is not only applicable to pig manure and poultry manure with different moisture contents, but also to organic solid waste such as animal manure, animal manure, and kitchen waste residue, including cow manure, sheep manure, rabbit manure, mink manure, and kitchen waste residue with various moisture contents.

[0058] (4) High degree of automation, optimized operation process, simple operation, safe and reliable system, low operating cost - This invention controls the automatic operation of the stirring component, feeding component and dosing component through the built-in pre-processing program of the control system. No manual intervention is required during the transfer, which reduces manpower input, improves the reliability and safety of system operation, and effectively reduces operating costs.

[0059] (5) Low water consumption, clean water recycling, green and environmentally friendly - The feeding component has stirring and gathering functions, which not only effectively solves the problem of difficult suction of sticky fecal waste with low moisture content, but also reduces the amount of water added by 20-30% compared with the existing fecal suction method, thereby saving dilution water consumption; the water circulation component adopts recycling of clean water, thus reducing the amount of wastewater generated by more than 50%, thereby reducing the amount of transportation and the workload of subsequent wastewater treatment. Therefore, the present invention is not only green and environmentally friendly, but also effectively reduces the cost of fecal waste treatment.

[0060] (6) No environmental pollution, clean and hygienic - The feeding, transfer and other processes of this invention adopt closed measures, with no odorous gas emissions, effectively controlling the spread of disease.

[0061] (7) The bottom of the water tank of the water circulation component is equipped with a sludge removal port, which allows for manual cleaning of sediment, avoiding damage to the pump caused by sediment in the cleaning water and extending the service life of the equipment.

[0062] (8) When this invention is applied to large-scale farms, there is no need to build conventional facilities such as transportation pipeline systems and intermediate treatment ponds. The project achieves the effects of small footprint, low investment and short construction period. Attached Figure Description

Detailed Implementation

[0072] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the scope of protection of the present invention.

[0073] This invention is used for the comprehensive treatment and transportation of manure and wastewater from livestock farms.

[0074] Please refer to the following: Figure 1 and Figure 2 The multi-functional pretreatment transfer vehicle for manure integrates functions such as loading, transportation, mixing, pretreatment and cleaning, and includes: vehicle body component 1, mixing component 2, feeding component 3, chemical dosing component 5, water circulation component 6 and control system 4, etc.

[0075] Please see Figure 3The vehicle body component 1 serves as the power source and carrier for the entire transfer vehicle, providing power for loading and transferring manure. It also houses the mixing component 2, the feeding component 3, the control system 4, the dosing component 5, and the water circulation component 6, performing the manure treatment function during manure transfer.

[0076] The mixing component 2 is fixed on the vehicle body component 1 and can rotate around itself. It is used to contain and mix the sewage at the same time. When the transport vehicle arrives at the destination and the mixing is completed, the sewage is unloaded.

[0077] The feeding component 3 is retractably mounted on the vehicle body component 1 and connected to the mixing component 2. It is used to crush, collect and mix the sewage in the sewage collection tank and then pump the sewage into the mixing component 2. After the transport vehicle arrives at the sewage collection tank, the feeding component 3 is placed into the sewage collection tank and the sewage is transported to the mixing component 2.

[0078] The dosing component 5 is fixed to the vehicle body component 1 and connected to the mixing component 2. It is used to contain conditioning drugs and add drugs to the feces in the mixing component 2 to complete the conditioning of the feces.

[0079] The water circulation component 6 is fixed to the rear of the vehicle body component 1 and connected to the stirring component 2. It is used to add water to the sewage in the sewage collection tank to improve the fluidity of the sewage, as well as to clean the stirring component 2 and complete the recycling of cleaning water.

[0080] The control system 4 is located at the front of the vehicle body component 1 and is connected to the mixing component 2 and the dosing component 5 respectively. The control system 4 has a pretreatment program installed inside to control the automated operation of the mixing component 2 and the dosing component 5 so as to achieve pretreatment of the transported manure on the way of transport.

[0081] The purpose of the pretreatment is to: adjust the properties of fecal waste by stirring and adding conditioning drugs, thereby disrupting the stability of polysaccharides and proteins or colloids on the surface of the fecal waste, reducing the viscosity of the fecal waste, releasing some interstitial water and bound water, improving the hydrophobicity of the fecal waste, and thus improving the flocculation of solid particles therein, so as to improve the efficiency of the subsequent solid-liquid separation process in the transfer operation.

[0082] The specific structural descriptions of each component of the multi-functional pretreatment transfer vehicle are as follows:

[0083] Please see Figure 1 The vehicle body component 1 adopts a Class II general-purpose chassis provided by existing vehicle manufacturers, and uses oil drive, electric drive or oil-electric hybrid drive.

[0084] Please see Figure 2The mixing component 2 includes a mixing tank 2-1, a reducer 2-2, a hydraulic system 2-3, a support 2-4, and an operating mechanism. The mixing tank 2-1 is a sealable hollow cylinder, mounted on the vehicle body component 1 at an angle and rotatably via the support 2-4 and bolts. An inlet / outlet is located at the top rear side. A tank cover seals the interior of the mixing tank 2-1 into a closed space for containing manure. This fully sealed mixing tank 2-1 effectively solves the problems of odor diffusion and waste spillage during manure transportation, ensuring cleanliness and hygiene during the transfer process and effectively controlling the potential spread of diseases during manure transportation. The hydraulic system 2-3 includes a variable displacement pump and a metering motor connected to each other. The variable displacement pump is connected to the vehicle body component 1, and the metering motor is connected to the reducer 2-2. The power from the vehicle body component 1 drives the variable displacement pump, converting mechanical energy into hydraulic energy, which is then transmitted to the metering motor. The metering motor drives the reducer 2-2, which in turn drives the mixing tank 2-1 to rotate, thus mixing the manure. The variable pump is connected to the control system 4 and transmits signals to it. The control system 4 controls the start, stop, and speed of the variable pump according to a built-in preprocessing program to control the rotation of the mixing tank 2-1, ensuring the mixing and conditioning effect of the manure. The operating mechanism is used to control the direction of the mixing tank 2-1. During transportation, the mixing tank 2-1 rotates forward to mix the manure, and during unloading, the mixing tank 2-1 reverses to push the manure out of the tank.

[0085] The feeding component 3 is disposed in a fixing groove on the vehicle body component 1. Please refer to Figure 4The system includes an auger pump 3-1, a suction hose 3-2, a baffle 3-4, a traction rod 3-5, a limiting plate 3-6, and an impeller 3-7. The auger pump 3-1 is located below the feeding component 3 and is used to suck up sewage. The auger pump 3-1 is driven by an auger pump motor 3-3 at its upper end, and its lower end has a suction port 3-10 for inserting sewage. One end of the suction hose 3-2 is connected to the auger pump 3-1, and the other end can pass through the inlet / outlet of the mixing tank 2-1 to input the sewage sucked by the auger pump 3-1 into the mixing tank 2-1. The baffle 3-4 is a circular plate with a central hole, fitted around the suction port 3-10 at the bottom of the auger pump 3-1, with its lower edge aligned with the edge of the suction port 3-10. It prevents sewage from accumulating and remaining in the area surrounding the side of the suction port 3-10, thereby guiding the sewage to be directly sucked into the suction port 3-10. The traction rod 3-5 is arranged along the axial direction of the auger pump 3-1, with its lower end fixedly connected to the baffle 3-4 and its upper end located at the upper auger pump motor 3-3. It is used to pull the baffle 3-4 up and down along the side wall of the auger pump 3-1. When the traction rod 3-5 pulls the baffle 3-4 upwards to retract and disengage from the area surrounding the suction port 3-10, it creates space for the impeller 3-7 to agitate the waste. When the traction rod 3-5 pushes the lower edge of the baffle 3-4 downwards to align with the edge of the suction port 3-10, it guides the waste directly into the suction port 3-10. The limiting plate 3-6 is located near the upper auger pump motor 3-3 and is used to limit the upward stroke of the traction rod 3-5. Two impellers 3-7 are symmetrically arranged on the outer side of the baffle 3-4 to agitate, crush, and mix the fecal sludge in the collection tank; these two impellers 3-7 are driven by the upper impeller motor 3-9 and rotate in opposite directions. (See also...) Figure 5 The lower end of the impeller 3-7 is fixedly equipped with a blade 3-8, which is located at the same horizontal position as the suction port 3-10. The blades 3-8 of the two impellers 3-7 are installed in opposite directions. The blades 3-8 are sickle-shaped and installed vertically. The upper edge of the blades 3-8 is inclined outward at an angle. Preferably, the angle is 60° so that the disturbance of the impeller 3-7 can achieve the best collection and gathering effect of the feces and sewage.

[0086] The specific operating principle of the suction feeding device 3 for different forms of fecal waste is as follows:

[0087] For watery pig manure, the sludge collection tank contains a mixture of manure, urine, and water with a water content of over 85% and good fluidity. After the transport vehicle arrives at the sludge collection tank of the farm, the auger pump 3-1 at the bottom of the feeding component 3 is put into the manure, and the outlet end of the suction hose 3-2 is connected to the mixing tank 2-1. The auger pump motor 3-3 is started directly to drive the auger pump 3-1 to suck the manure into the mixing tank 2-1.

[0088] For dry-cleaned pig and cow / sheep manure, the manure and urine in the collection tank are mixed, with a water content of less than 85% and poor fluidity. After the transport vehicle arrives at the collection tank, the auger pump 3-1 at the bottom of the feeding component 3 is used to put the manure into the collection tank. Then, the traction rod 3-5 is pushed down to move the baffle 3-4 down, so that the lower edge of the baffle 3-4 is aligned with the edge of the suction port 3-10 to block and guide the manure. The outlet end of the suction hose 3-2 is connected to the mixing tank 2-1. Then, the impeller motor 3-9 is started to drive the impeller 3-7 to rotate. Since the two impellers 3-7 rotate in opposite directions, they are in a collecting state, thereby collecting the manure towards the suction port 3-10. Then, the auger pump motor 3-3 is started to drive the auger pump 3-1, which transports the manure into the mixing tank 2-1.

[0089] For poultry manure removed from poultry houses, the manure in the collection tank is generally in a semi-solid state, with a water content of less than 85%, poor fluidity, viscous texture, and contains poultry feathers and other substances. After the transport vehicle arrives at the collection tank, water is first added to the manure, with the amount of water being 20-30% of the manure volume. Then, the traction rod 3-5 is pulled up to move the baffle 3-4 upwards. Next, the feeding component 3 is placed into the manure, and the outlet end of the suction hose 3-2 is connected to the mixing tank 2-1. Then, the impeller motor 3-9 is started to drive the impeller 3-7 to rotate. The impeller 3-7 is in the stirring function state, stirring the manure and water in the collection tank, thereby improving the fluidity of the manure. After the impeller 3-7 rotates and stirs for 3-5 minutes, the auger pump motor 3-3 is started to drive the auger pump 3-1 to transport the manure into the mixing tank 2-1.

[0090] Please see Figure 2The dosing component 5 includes a dosing pump 5-1, a solenoid valve 5-3, a dosing pipe 5-4, and a medicine tank 5-5. The medicine tank 5-5 is mounted on the vehicle body component 1 and is used to store medicines for treating manure. The dosing pump 5-1 is connected to the upper part of the medicine tank 5-5, and the dosing pump 5-1 is connected to the inlet and outlet of the mixing tank 2-1 through the solenoid valve 5-3 and the dosing pipe 5-4. A manual shut-off valve 5-2 is connected to the pipeline between the dosing pump 5-1 and the solenoid valve 5-3 for manually opening and closing the dosing pipeline. The dosing pump 5-1 and the solenoid valve 5-3 are respectively connected to the control system 4 and transmit signals. According to the needs of fecal pretreatment, the control system 4 first opens the solenoid valve 5-3 according to the logic of the built-in pretreatment program, and then opens the dosing pump 5-1 after 1 minute to pump the medicine in the medicine tank 5-5 into the fecal matter in the mixing tank 2-1. The running time of the dosing pump 5-1 is controlled by the program and the value is adjustable. The running time is determined according to the amount of fecal matter, the concentration of medicine, and the operating frequency of the dosing pump 5-1. After the running time of the dosing pump 5-1 reaches the set value, the dosing pump 5-1 is turned off, and the solenoid valve 5-3 is turned off after 1 minute, thereby completing the automatic control dosing program for fecal matter property conditioning during the pretreatment process.

[0091] Please refer to the following: Figure 2 and Figure 6 The water circulation component 6 includes a circulation pump 6-1, a manual valve 6-2, a water supply pipe 6-3, a return pipe 6-4, an external pipe 6-6, and a water tank 6-9. The water tank 6-9 is fixedly mounted on the vehicle body component 1 and is used to store water. A sludge removal port 6-5 is provided at the bottom for periodically cleaning the sediment inside the water tank 6-9, preventing sediment from entering the circulation pump 6-1 and the water circuit, causing pump wear or pipe blockage. The circulation pump 6-1 is fixedly connected to the lower part of the water tank 6-9, and can also be an internal pump, used to provide power for water delivery. The circulation pump 6-1 is connected to the water supply pipe 6-3 through the manual valve 6-2. The water supply pipe 6-3 is a flexible hose, with its free end able to connect to the inlet / outlet of the mixing tank 2-1 of the stirring component 2, for injecting water into the mixing tank 2-1. A jet port 6-8 is provided at the free end of the water supply pipe 6-3. The circulation pipe 6-4 is connected at one end to the water tank 6-9 and at the other end to the inner cavity of the mixing tank 2-1, for the recycling of clean water. (See...) Figure 2 The external pipeline 6-6 is a flexible hose, with one end connected to the water tank 6-9 and the other end equipped with an E-type quick connector 6-7 for connecting to an external water source to replenish water into the water tank 6-9.

[0092] When water needs to be drawn from the outside, the external water source pipeline is quickly connected using the E-type quick connector 6-7 to fill the water tank 6-9; the operation is simple and quick. When water needs to be added to sewage, the manual valve 6-2 is opened, the circulation pump 6-1 is started, and water is added to the sewage through the water filling pipeline 6-3. After adding water, the circulation pump 6-1 is turned off. When the mixing tank 2-1 needs to be cleaned after the vehicle has finished unloading, the water filling pipeline 6-3 is manually removed, the circulation pump 6-1 is turned on, and the mixing tank 2-1 is rinsed inside and out. The rinsing water is returned to the water tank 6-9 through the circulation pipeline 6-4 for recycling. When sediment appears at the bottom of the water tank 6-9, the debris is removed through the sludge removal port 6-5.

[0093] The control system 4 includes a control box and its internal PLC control module, signal transmission device, and control panel. Before the transfer of sewage, the operator inputs control parameters into the PLC control module through the control panel according to the different forms of sewage to be treated, forming a built-in pretreatment program. Then, on the transfer route, the control system 4 controls the mixing component 2 and the chemical dosing component 5 to operate automatically, completing the pretreatment of the transferred sewage without placing an extra burden on the driver or affecting driving safety.

[0094] The pretreatment procedures for adding chemicals and stirring vary depending on the form of fecal waste in the control system 4. The control logic is as follows: Figure 7 .

[0095] For watery pig manure, which is a mixture of feces, urine and water with a water content of over 85%, it has good fluidity and good solid-liquid separation effect, so no pretreatment is required during transportation.

[0096] For dry-cleaned pig manure and cow and sheep manure, which are mixtures of feces and urine with a water content of less than 85% and poor fluidity, during transportation, the variable pump of the hydraulic system 2-3 in the stirring component 2 is controlled to make the stirring tank 2-1 rotate at a speed of 0.5 to 1 r / min to slowly stir the manure. The mechanical force of stirring and the centrifugal force of rotation increase the speed of water separation in the manure.

[0097] For poultry manure from farms, which is in a semi-solid state with a water content below 85%, poor fluidity, viscous texture, and contains poultry feathers and other substances, quicklime is manually added to the mixing tank 2-1 during transport. The mixing tank 2-1 of the mixing component 2 is controlled to rotate at a speed of 2-4 r / min for 5-10 minutes to perform preliminary treatment of the manure. The amount added is 2-4% of the manure volume. The high temperature and alkaline environment generated by the quicklime destroys the sticky substances on the surface of the manure and releases bound water and interstitial water, thereby improving the hydrophobicity of the manure. Then, the control system 4 opens the solenoid valve 5-3 on the dosing pipe 5-4 of the dosing component 5 according to the pretreatment program. After 1 minute, the dosing pump 5-1 is started to add a cationic polyacrylamide solution (PAM) with a concentration of 1-5‰ to the manure in the mixing tank 2-1 to further improve the flocculation effect of solids in the manure. After the amount of conditioning drug added reaches the predetermined value, the dosing pump 5-1 and the solenoid valve 5-3 are closed in sequence, and the pretreatment program is completed.

[0098] In summary, the integrated treatment and transportation method for fecal waste described in this invention includes the following steps, please refer to [link / reference]. Figure 8 :

[0099] Step 1, Preparation Stage – Based on the form of the feces and sewage to be transferred and treated, determine the pretreatment control parameters and input them into the control system 4, establish a pretreatment program for fecal and sewage condition conditioning, inject water into the water tank 6-9 through the water circulation component 6, and add the corresponding fecal and sewage condition conditioning drugs to the drug tank 5-5 of the dosing component 5.

[0100] The manure is classified into poultry manure with a moisture content of less than 85%, dry-cleaned pig manure with a moisture content of less than 85%, and water-soaked pig manure with a moisture content of 85% or more.

[0101] Step two, loading stage—Depending on the form of the transported manure, the manure is drawn into the mixing unit 2 by the feeding component 3 using different methods. After completion, the mixing tank 2-1 is sealed.

[0102] For watery pig manure, place the auger pump 3-1 at the bottom of the feeding component 3 into the manure in the sludge collection tank, and connect the outlet end of the suction hose 3-2 into the mixing tank 2-1. Directly start the auger pump motor 3-3 to drive the auger pump 3-1 to suck the manure into the mixing tank 2-1. After completion, seal the mixing tank 2-1.

[0103] For dry-cleaned pig manure and cow and sheep manure, first push down the traction rod 3-5 so that the lower edge of the baffle 3-4 is aligned with the edge of the suction port 3-10. Adjust the feeding component 3 to the collection function state. Then put the auger pump 3-1 at the bottom of the feeding component 3 into the manure in the collection tank. At the same time, connect the outlet end of the suction hose 3-2 into the mixing tank 2-1. Then start the impeller motor 3-9 to drive the impeller 3-7 to rotate. Then start the auger pump motor 3-3 to drive the auger pump 3-1 to transport the manure into the mixing tank 2-1. After completion, seal the mixing tank 2-1.

[0104] For poultry manure, firstly, water is added to the manure through the water circulation component 6, with the water volume being 20-30% of the manure volume. Then, the traction rod 3-5 is pulled up to move the baffle 3-4 upward, adjusting the feeding component 3 to the stirring function state. Next, the auger pump 3-1 at the bottom of the feeding component 3 is placed into the manure in the collection tank, and the outlet end of the suction hose 3-2 is connected to the mixing tank 2-1. Then, the impeller motor 3-9 is started to drive the impeller 3-7 to rotate, stirring the manure and water in the collection tank. After stirring for 3-5 minutes, the auger pump motor 3-3 is started to drive the auger pump 3-1 to transport the manure into the mixing tank 2-1. After completion, the mixing tank 2-1 is sealed.

[0105] Step 3, Transfer and Pre-treatment Stage—The transfer vehicle embarks on the transfer route, and simultaneously, the control system 4 automatically controls the stirring component 2 and the dosing component 5 to operate according to different programs based on the form of the transferred manure, thereby achieving automated pre-treatment of the transferred manure and completing the conditioning of the manure's properties:

[0106] For watery pig manure, no pretreatment is required;

[0107] For dry-cleaned pig manure and cattle and sheep manure, the mixing tank 2-1 of the mixing component 2 is controlled to rotate at a speed of 0.5 to 1 r / min to mix the manure;

[0108] For poultry manure, first add quicklime to the mixing tank 2-1, the amount of which is 2-4% of the manure volume. Control the mixing tank 2-1 of the mixing component 2 to rotate at a speed of 2-4 r / min for 5-10 minutes. Then start the dosing pump 5-1 and add a cationic polyacrylamide solution (PAM) with a concentration of 1-5‰ to the manure in the mixing tank 2-1. After the amount of conditioning drug added reaches the predetermined value, turn off the dosing pump 5-1. The manure pretreatment is complete.

[0109] Step 4, unloading stage—After the transfer vehicle reaches the transfer endpoint and the pretreatment is completed, the stirring component 2 is opened, and the stirring tank 2-1 unloads the conditioned manure into the solid-liquid separation device.

[0110] Step 5, Cleaning Stage – After unloading, open the manual valve 6-2 of the water circulation component 6, start the circulation pump 6-1, and manually operate the water supply pipeline 6-3 to rinse the inside and outside of the mixing tank 2-1, thus completing the cleaning of the mixing component 2; remove the debris from the water tank 6-9 through the slag removal port 6-5.

[0111] The following are embodiments of the present invention.

[0112] Example 1

[0113] In large-scale chicken farms, each chicken house has a waste collection pond. Chicken manure is highly viscous, with a moisture content of approximately 80%-85%, and poor flowability. After the transport vehicle arrives at the waste collection pond, the feeding component 3 is placed into the pond. The water circulation component 6 adds a small amount of water to the pond, and then the feeding component 3 is turned on to enter the stirring function. The impeller 3-7 stirs for 5 minutes. After stirring, the push plate 3-4 is lowered, and the auger pump 3-1 is turned on to transport the manure to the mixing tank 2-1. After completion, the tank is sealed with a lid. After the manure is fed, the pretreatment program of the control system 4 is started, and the transport vehicle moves to transport the manure. According to the pretreatment program settings, 2% quicklime is first added to the manure and stirred for 5 minutes, with the stirring component 2 working synchronously. Then, the dosing component 5 is started to add a 2‰ concentration of cationic PAM (cationic polyacrylamide solution) to the mixing tank 2-1 and stir for 20 minutes at a stirring speed of 2-4 r / min. After the transport arrives at the destination, the pretreatment process ends. The mixing unit 2 unloads the pretreated manure into the high-efficiency solid-liquid separation device. The moisture content of the manure after solid-liquid separation can reach 65%-70%. After unloading, the water circulation unit 6 is started, the circulation pump 6-1 is turned on, and the water supply hose 6-3 is held by hand to rinse the inside and outside of the mixing tank 2-1. The rinsing water returns to the water tank 6-9 for temporary storage through the return pipe 6-4. The sludge removal port 6-5 at the bottom of the water tank 6-9 is opened periodically to clean the sediment in the sludge collection trough, preventing sediment from entering the circulation pump 6-1 and causing pump wear and blockage.

[0114] Example 2

[0115] In large-scale pig farms using a dry manure cleaning system, each pigpen has a collection pit outside. The pig manure has low moisture content and lacks fluidity. After the transport vehicle arrives at the collection pit, the feeding unit 3 is placed inside, and the baffle 3-4 is pushed down to activate the collection function. The impeller 3-7 in the feeding unit 3 is opened to collect and gather the manure. Then, the auger pump 3-1 is turned on to transport the manure to the mixing tank 2-1, which is then sealed with a lid. After the manure loading is complete, the mixing unit 2 is started at a speed of 0.5-1 r / min. Upon arrival at the destination, the mixing stops, and the pretreatment process ends. The mixing unit 2 unloads the pretreated manure into a high-efficiency solid-liquid separator, where the separated manure has a moisture content of approximately 65%. After unloading, the water circulation unit 6 is started, the circulation pump 6-1 is turned on, and the water inlet hose 6-3 is used to flush the inside and outside of the mixing tank 2-1. The flushing water returns to the water tank 6-9 via the return pipe 6-4 for temporary storage. Regularly open the bottom sludge removal port 6-5 of the water tank 6-9 to clean the sludge in the sludge collection trough, and prevent the sludge from entering the circulating pump 6-1 and causing pump wear and blockage.

[0116] Example 3

[0117] For small-scale farms, the operation steps are basically the same depending on the type of farm, the type of manure, and the transportation distance and time.

[0118] This invention is applicable to farms of all sizes, including large-scale farms and smaller farms. Furthermore, this invention is not only applicable to pig and poultry manure, but also to various organic solid wastes including cow manure, sheep manure, rabbit manure, mink manure, and kitchen waste residue, as well as other organic wastes with varying moisture contents such as food waste residue and other food processing waste.

[0119] This invention provides a closed-loop transportation system for livestock farm manure after mechanical feeding. During the journey, the manure is simultaneously sorted and pre-treated automatically. The process is clean and environmentally friendly, increasing the efficiency of subsequent solid-liquid separation by at least 12%, thus improving the efficiency of manure resource utilization and effectively reducing costs.

[0120] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made in accordance with the content of this application should be considered within the technical scope of the present invention.
