Description

Technical Field

[0001] The present invention relates to the transfer and pretreatment of manure and sewage, and specifically to a multifunctional pretreatment transfer vehicle and an integrated treatment and transfer method for manure and sewage, belonging to the technical field of environmental protection governance in the breeding industry. Background Art

[0002] In China, the annual output of livestock and poultry manure and sewage in the breeding industry is about 3.05 billion tons. Livestock and poultry manure and sewage are rich in organic matter, nitrogen, phosphorus and other nutrients, which are utilizable resources. They are beneficial if used and harmful if discarded. In the "Guiding Opinions on Accelerating the Comprehensive Green Transformation of Agricultural Development and Promoting Rural Ecological Revitalization" issued by the Chinese government departments, it is required that by 2030, the level of waste resource utilization should be significantly improved, and it is clearly proposed that the comprehensive utilization rate of livestock and poultry manure and sewage should reach more than 85%. The first step affecting the comprehensive utilization rate of livestock and poultry manure and sewage is collection and transfer. The operation level of manure and sewage collection and transfer not only affects the comprehensive utilization rate of manure and sewage and the corresponding resource disposal benefits, but also has a greater impact on the environmental sanitation in and around the farms.

[0003] The large-scale farms in China are mainly pig farms, poultry farms such as chicken, duck and goose farms, cattle and sheep farms, etc. The manure and sewage generated usually include pig manure, poultry manure, cattle and sheep manure, etc. According to the different moisture contents, manure and sewage show different states during collection and transfer. Manure and sewage of cattle, sheep and pigs are generally divided into dry cleaning manure and flushing manure. Dry cleaning manure is a mixture of feces and urine, with a high content of solid substances, low moisture content and poor fluidity; flushing manure is a mixture of feces, urine and water, with a high moisture content, low viscosity and certain fluidity. Poultry manure is viscous and generally in a semi-solid state, with a moisture content of about 85% or less, poor fluidity, high viscosity, and accompanied by substances such as poultry feathers, and it is not easy to be directly pumped and transported by a pump. Therefore, different operation methods need to be adopted for the collection and transfer of manure and sewage in farms for different states of manure and sewage, and it is difficult to use the same method to treat different states of manure and sewage.

[0004] Currently, the main method for collecting manure and sewage in farms is the dry cleaning manure method, where manure and sewage are cleaned outside the house by artificial or mechanical use of scrapers and stored centrally; the transfer method is to manually bag or load the manure and sewage in bulk and pull it away by vehicle, or inject a large amount of water into the sewage collection pool and then pull it away by a manure suction vehicle after suction. To promote rural revitalization and the comprehensive utilization of livestock and poultry manure and sewage at the county level, county-level centralized disposal centers for manure and sewage resource utilization have been built everywhere. A third-party agency regularly collects manure and sewage from each farm household and transports it to the manure and sewage disposal center for centralized disposal of manure and sewage.

[0005] However, the above-mentioned current manure and sewage transfer methods have the following problems:

[0006] 1. When the fecal sewage is loaded into the trolley manually or by a forklift driven manually and then transported in an open bulk manner, there are problems such as fecal sewage scattering during transportation, causing environmental pollution, the diffusion of malodorous gases affecting the surrounding air, affecting the sanitary environment, and causing the spread of diseases.

[0007] 2. When using a fecal sewage suction truck for transportation, when the fecal sewage has a high solid content, a water content lower than 85%, and poor fluidity, such as dry-cleaned pig manure, cattle and sheep manure, and viscous poultry manure containing feathers, it is difficult for the fecal sewage suction truck to suck and is easy to block the pump. At this time, a large amount of water needs to be added to the fecal sewage for dilution in advance. The amount of added water is usually more than 80% of the fecal sewage volume until the water content of the fecal sewage reaches 90% and has good fluidity before the fecal sewage suction truck can play its role. The result of such treatment is an increase in the volume of fecal sewage, an increase in transportation costs; at the same time, it causes waste of water resources and an increase in the workload of subsequent wastewater treatment, resulting in an increase in treatment costs and poor economy.

[0008] 3. Existing fecal sewage transfer vehicles generally have defects such as single function, low transfer efficiency, small application range, low water resource utilization rate, and high proportion of fecal sewage resource disposal cost.

[0009] After retrieval, it is found that the Chinese patent "A Transfer Device for Recycling Fecal Sewage in a Farm" (authorization announcement number CN217197892 U, authorization announcement date August 16, 2022) discloses a fecal sewage transfer vehicle for loading, crushing and transporting fecal sewage in a farm to farmland for direct spraying, including a vehicle body, a carriage, an automatic discharging component and a cutting component; among them, the vehicle body is used for transportation, the carriage is used for accommodating fecal sewage, the automatic discharging component is used for lifting the feces on the ground and pouring them into the carriage, and the cutting component is used for crushing the feces.

[0010] The above-mentioned existing technology can only be applicable to fecal sewage with a relatively low water content at first, and it is difficult to adapt to the waterlogged feces with a high water content, so the application range is relatively narrow; secondly, it has few functions and can only complete the crushing and transportation of fecal sewage without other treatments, and it is impossible to make more pretreatment of fecal sewage by making full use of time during transportation, especially during a relatively long transfer journey.

[0011] In short, the existing fecal sewage transfer vehicles have the following deficiencies:

[0012] 1) Narrow application range - Existing transfer vehicles can either adapt to pig manure and poultry manure with low water content and poor fluidity in dry-cleaned manure, or adapt to waterlogged feces with high water content and good fluidity, and cannot be applicable to the transfer of fecal sewage with various water contents at the same time.

[0013] 2) Single function - Except for the functions of loading and transporting fecal sewage, existing transfer vehicles rarely have other pretreatment functions for fecal sewage at the same time, so they become a link with low disposal efficiency in the process of fecal sewage resourceization.

[0014] 3) High water resource consumption - When dealing with fecal sewage with low moisture content and a large proportion of solid substances, the existing suction-type fecal sewage trucks need to consume a large amount of dilution water to improve the fluidity of the fecal sewage, resulting in a waste of water resources.

[0015] 4) Poor economy - The low utilization rate of transportation time caused by the single function leads to low transfer efficiency; the increase in transportation volume and subsequent wastewater treatment workload caused by excessive water resource consumption leads to an increase in the cost of fecal sewage transfer and treatment; therefore, the economy of the existing transfer trucks is very poor. Summary of the Invention

[0016] In order to overcome the drawbacks of the existing fecal sewage transfer technology, the present invention proposes a multi-functional pretreatment transfer truck and an integrated treatment transfer method for fecal sewage, which integrates functions such as loading, transportation, stirring, pretreatment, and cleaning, achieving the purposes of improving transfer efficiency, conditioning the properties of fecal sewage, saving water resources, and reducing costs, and obtaining the effects of optimizing the process, convenient operation, wide application range, energy conservation and environmental protection, and good economy.

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

[0018] A multi-functional pretreatment transfer truck for fecal sewage, where the fecal sewage includes poultry manure, and includes but is not limited to dry-cleaned pig manure, flushing pig manure, and livestock manure such as cattle and sheep manure. Among them, 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 flushing pig manure is 85% or above; it is characterized in that: the pretreatment transfer truck integrates functions such as loading, transportation, stirring, pretreatment, and cleaning, and includes:

[0019] A vehicle body component, which is a movable basic carrier for providing power to load and transfer fecal sewage;

[0020] A stirring component, fixed on the vehicle body component, for loading, stirring, and discharging fecal sewage, including a stirring tank that can rotate around itself and can be fully enclosed, and a variable pump, a fixed-displacement motor, and a speed reducer that are sequentially drivingly connected to the stirring tank;

[0021] A feeding component, which is detachably arranged on the vehicle body component and can be connected to the stirring component, for crushing, stirring, collecting, and gathering fecal sewage and then sucking and transporting the fecal sewage into the stirring tank, including an auger pump, a sewage suction hose, a baffle, and an impeller; the auger pump is used to suck fecal sewage, one end of the sewage suction hose is connected to the auger pump, and the other end can be inserted into the stirring tank. The baffle is sleeved around the sewage suction port at the bottom of the auger pump and can move up and down to realize the switching between the stirring function state and the gathering function state. Two impellers are arranged on the outer sides of the left and right of the baffle and rotate in opposite directions to disturb, crush, gather, and stir fecal sewage;

[0022] The chemical dosing component is fixed on the vehicle body component and connected to the stirring component, and is used to accommodate the drugs for fecal sewage property conditioning and add drugs into the stirring tank to complete the pretreatment of fecal sewage. It includes a chemical dosing pump, a solenoid valve, a chemical dosing pipe and a medicine barrel. The medicine barrel is used to store the drugs for property conditioning. One end of the chemical dosing pump is connected to the medicine barrel, and the other end is communicated with the stirring tank through the solenoid valve and the chemical dosing pipe in sequence, and is used to transport the drugs for property conditioning into the stirring tank;

[0023] The water circulation component is fixed on the vehicle body component and connected to the stirring component, and is used to add water to fecal sewage, clean the stirring component and complete the recycling of 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 the 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 stirring tank to inject water into the stirring 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 stirring tank for the recycling of cleaning water;

[0024] The control system is arranged on the vehicle body component and is respectively connected to the stirring component and the chemical dosing component. It has a pretreatment program implanted inside and is used to control the automatic operation of the stirring component and the chemical dosing component to achieve the pretreatment of fecal sewage;

[0025] The pretreatment refers to: conditioning the properties of fecal sewage by stirring and adding drugs for property conditioning, increasing the speed of water separation in fecal sewage, destroying the stability of polysaccharide and protein colloidal substances on the surface of fecal sewage, releasing interstitial water and bound water, thereby reducing the viscosity of fecal sewage, increasing the hydrophobicity of fecal sewage, and further increasing the flocculability of solid particles therein to improve the effect of solid-liquid separation of fecal sewage.

[0026] As a further improvement, the control system is respectively connected to the variable pump of the stirring component and the chemical dosing pump and solenoid valve of the chemical dosing component, and signal transmission is carried out between them. The control system controls the start-stop and rotation 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 operation sequence and duration of the chemical dosing pump and the solenoid valve, so as to complete the automatic operation of stirring and chemical dosing operations during the pretreatment process.

[0027] As a further improvement, the gathering function state of the feeding component refers to: the baffle moves downwards and the lower edge is aligned with the edge of the sewage suction port of the screw pump to block the fecal sewage from staying in the area beside the sewage suction port and guide the fecal sewage to gather towards the sewage suction port. Two reversely rotating impellers collect and gather the fecal sewage towards the sewage suction port, so that the fecal sewage can be directly sucked into the sewage suction port;

[0028] The stirring function state of the feeding component means that the baffle moves upward and retracts, disengaging from the area around the sewage suction port, creating space for the impeller, thereby achieving full stirring of the fecal sewage.

[0029] As a further improvement, blades are fixedly installed at the lower end of the impeller. The blades are located at the same horizontal position as the sewage suction port. The blades of the two impellers are installed in the opposite direction. The blades are sickle-shaped, with the upper edge inclined outward at an angle.

[0030] As a further improvement, the inclination angle is 60°, so as to achieve the best collection and gathering effect of the impeller on the fecal 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 addition amount of quicklime is 2-4% of the volume of the fecal sewage.

[0033] As a further improvement, the feeding component further includes a towing rod and a limit plate; the towing rod is arranged along the axial direction of the screw pump, the lower end is fixedly connected to the baffle, and the upper end is located at the upper part of the feeding component, and is used to operate the up and down movement of the baffle above the fecal sewage. The limit plate is arranged near the upper part of the feeding component and is used to limit the upward travel of the towing rod.

[0034] As a further improvement, the running time of the dosing pump is determined according to the amount of fecal sewage, the dosing concentration and the running frequency of the dosing pump. The value is adjustable and input into the control system. When the running time of the dosing pump reaches the set value, the dosing component stops running.

[0035] As a further improvement, the water circulation component further includes an external pipeline, one end is connected to the water tank, and the other end is connected to an external water source through an E-type quick connector to supplement water into the water tank. A slag cleaning port is arranged at the lower part of the water tank for regularly 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 sewage realized by the above-mentioned multifunctional pretreatment transport vehicle, which includes the following steps:

[0038] Step 1, preparation stage - according to the form of the fecal sewage of the transportation object, determine the pretreatment control parameters and input them into the control system, establish a pretreatment program for fecal sewage property conditioning, inject water into the water tank, and add the property conditioning drugs for the corresponding fecal sewage to the medicine barrel of the dosing component;

[0039] Step 2, Loading Stage - According to the form of the transported manure, the manure is sucked into the mixing component in different ways through the feeding component. After completion, the mixing tank is sealed:

[0040] For the bubble manure of pigs, place the screw pump into the manure, insert the sewage suction hose into the mixing tank, and directly start the screw pump to suck and discharge the manure into the mixing tank;

[0041] For the dry-cleaned manure of pigs and the manure of cattle and sheep, first lower the baffle so that its lower edge aligns with the edge of the sewage suction port, adjust the feeding component to the gathering function state, then place the screw pump into the manure, insert the sewage suction hose into the mixing tank at the same time, then start the impeller to rotate, and then start the screw pump to transport the manure into the mixing tank;

[0042] For poultry manure, first add water to the manure through the water circulation component, then raise the baffle, adjust the feeding component to the mixing function state, then place the screw pump into the manure, insert the sewage suction hose into the mixing tank, then start the impeller to rotate to mix the manure and water. After mixing for 3 - 5 minutes, start the screw pump to transport the manure into the mixing tank;

[0043] Step 3, Transfer and Pretreatment Stage - The transfer vehicle drives onto the transfer route. At the same time, the control system automatically controls the mixing component and the dosing component to operate in different programs according to the form of the transported manure, realizing the automatic pretreatment of the transported manure and completing the conditioning of the properties of the manure;

[0044] Step 4, Discharging Stage - After the transfer vehicle reaches the destination and the pretreatment is completed, open the mixing component, and the mixing tank unloads the manure after the property conditioning treatment;

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

[0046] As a further improvement, the automatic pretreatment method for manure of different forms is as follows:

[0047] For the bubble manure of pigs, no pretreatment is performed;

[0048] For the dry-cleaned manure of pigs and the manure of cattle and sheep, control the mixing tank to rotate to mix the manure;

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

[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 addition amount of quicklime is 2 - 4% of the volume of the manure, and the concentration of the cationic polyacrylamide solution is 1 - 5‰.

[0051] As a further improvement, in the second step, the water addition amount is 20 - 30% of the amount of the manure.

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

[0053] An application of the above - mentioned comprehensive treatment and transportation method for manure in the transportation operation of various moisture - content manures including but not limited to livestock manure such as rabbit manure and mink manure, and organic solid wastes including but not limited to the tailings of food waste treatment and food processing wastes.

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

Mixing improves the speed of water segregation in manure through mechanical force and centrifugal force; the high temperature and alkaline environment generated by quicklime in the conditioning drug destroy the stability of polysaccharide and protein - like colloidal substances on the surface of manure, releasing bound water and interstitial water, thereby reducing the viscosity of manure and increasing its hydrophobicity; the cationic polyacrylamide solution (PAM) in the conditioning drug further improves the flocculation of solid particles therein. The improvement of manure properties creates favorable conditions for the subsequent solid - liquid separation process, greatly enhancing the effect of solid - liquid separation, increasing the solid - liquid separation efficiency by 12%, and reducing the moisture content of manure after solid - liquid separation to 65%, thus promoting the improvement of the overall efficiency of manure resource disposal.

[0056] (2) High degree of integration, improving the efficiency of manure transportation operation - the transport vehicle integrates functions of loading, transporting, mixing, pretreatment, and cleaning. It not only has the usual loading and transporting functions, but also has the functions of manure property conditioning and cleaning, reducing the investment in manure disposal equipment; during the transportation of manure, the pretreatment process is simultaneously carried out, saving operation time, improving time utilization rate, and greatly enhancing the transportation operation efficiency.

[0057] (3) Good economy and wide application range, capable of treating manure and sewage from various forms of farms - the feeding component, stirring component, medicine adding component and control system of the transfer vehicle can perform different effective operation operations according to different forms of manure and sewage of the treatment object: the feeding component has multiple functional states such as feeding, stirring, collecting and gathering, etc., and can cope with various manure and sewage conditions of farms. The control system can be built-in with pretreatment programs for different forms of manure and sewage, so the diversity of manure and sewage types treated by the present invention is greatly expanded; the present invention can not only be applied to pig manure and poultry manure with different moisture contents, but also be applied to organic solid wastes such as cow manure, sheep manure, rabbit manure, mink manure, tailings from kitchen waste treatment, food processing waste, etc. including various moisture contents of livestock manure, animal manure, tailings from kitchen waste, etc.

[0058] (4) High degree of automation, optimized operation process, simple operation, safe and reliable system, and low operation cost - the present invention controls the automatic operation of the stirring component, feeding component and medicine adding component through the built-in pretreatment program of the control system, without manual intervention during transportation, reducing labor input, improving the reliability and safety of system operation, and effectively reducing the operation cost.

[0059] (5) Less water resource consumption, clean water recycling, green and environmental protection - the feeding component has the functions of stirring and gathering, which not only effectively solves the problem of difficult suction of viscous manure and sewage with low moisture content, but also reduces the water addition by 20 - 30% compared with the existing manure pumping method, thus saving dilution water consumption; the water circulation component recycles the clean water, so the wastewater generation amount is reduced by more than 50%, thus reducing the transportation volume and the workload of subsequent wastewater treatment. Therefore, the present invention is not only green and environmental protection, but also effectively reduces the manure and sewage treatment cost.

[0060] (6) No pollution to the environment, clean and hygienic - the present invention takes sealing measures in the feeding, transportation and other links, without odor gas emission, effectively controlling the spread of diseases.

[0061] (7) The bottom of the water tank of the water circulation component is provided with a slag cleaning port, which can manually clean the sediment, avoiding the damage of the sediment in the cleaning water to the pump and extending the service life of the equipment.

[0062] (8) When the present invention is applied to large-scale farms, there is no need to build conventional facilities such as transportation pipeline systems and intermediate treatment ponds, and the project realizes the effects of small floor area, small investment and short construction period.

[0082] The specific structures of the components of the multifunctional pretreatment transporter are described as follows:

[0083] Please refer to Figure 1 , the vehicle body component 1 adopts a type II general chassis provided by existing vehicle manufacturers, and uses oil drive, electric drive or hybrid drive.

[0084] Please refer to Figure 2, the stirring component 2 includes a stirring tank 2-1, a speed reducer 2-2, a hydraulic system 2-3, a bracket 2-4 and a control mechanism. The stirring tank 2-1 is a closable hollow cylinder, which is obliquely and rotatably mounted on the vehicle body component 1 through the bracket 2-4 and bolts. The top of the rear side is provided with a feeding and discharging port, and the inside of the stirring tank 2-1 is sealed by a tank cover to form a closed space for accommodating fecal sewage. The fully sealed stirring tank 2-1 effectively solves the problems of odor diffusion and dirt scattering during the transportation of fecal sewage, ensures the cleanliness and hygiene during the transfer process, and effectively controls the spread of diseases that may occur during the fecal sewage transfer process. The hydraulic system 2-3 includes a variable pump and a fixed-displacement motor that are connected to each other. The variable pump is connected to the vehicle body component 1, and the fixed-displacement motor is connected to the speed reducer 2-2; the power of the vehicle body component 1 drives the variable pump, converts mechanical energy into hydraulic energy and transmits it to the fixed-displacement motor, and the fixed-displacement motor then drives the speed reducer 2-2, and further the speed reducer 2-2 drives the stirring tank 2-1 to rotate to stir the fecal sewage. The variable pump is connected to the control system 4 and signals are transmitted therebetween. The control system 4 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 2-1 and ensure the stirring and property conditioning effects of the fecal sewage. The control mechanism is used to control the steering of the stirring tank 2-1. During transportation, the stirring tank 2-1 rotates forward to stir the fecal sewage, and during unloading, the stirring tank 2-1 rotates backward to push the fecal sewage out of the tank.

The screw pump 3-1 is located at the lower part of the feeding component 3 and is used for sucking manure. The screw pump 3-1 is driven by a screw pump motor 3-3 at its upper end, and a sewage suction port 3-10 capable of inserting into manure is provided at the lower end. One end of the sewage suction hose 3-2 is connected to the screw pump 3-1, and the other end can lead into the inlet and outlet of the mixing tank 2-1 to input the manure sucked by the screw pump 3-1 into the mixing tank 2-1. The baffle 3-4 is a circular plate with a central hole, sleeved around the sewage suction port 3-10 at the bottom of the screw pump 3-1, and the lower edge is aligned with the edge of the sewage suction port 3-10, and is used to block the manure from gathering and staying in the surrounding area on the side of the sewage suction port 3-10, so as to guide the manure to be directly sucked into the sewage suction port 3-10. The towing rod 3-5 is arranged along the axial direction of the screw pump 3-1, the lower end is fixedly connected to the baffle 3-4, and the upper end is located at the screw pump motor 3-3 in the upper part, and is used to pull the baffle 3-4 to move up and down along the side wall of the screw pump 3-1; when the towing rod 3-5 pulls the baffle 3-4 upwards to retract and disengage from the surrounding area of the sewage suction port 3-10, a space for stirring the manure is created for the impeller 3-7, and when the towing rod 3-5 pushes the lower edge of the baffle 3-4 downwards to align with the edge of the sewage suction port 3-10, the manure can be directly guided to be sucked into the sewage suction port 3-10. The limit plate 3-6 is arranged near the screw pump motor 3-3 in the upper part and is used to limit the upward stroke of the towing rod 3-5. Two impellers 3-7 are symmetrically arranged on the outer side of the baffle 3-4 and are used to disturb, crush, and stir the manure in the sewage collection tank; the two impellers 3-7 are driven by an impeller motor 3-9 in the upper part and rotate in opposite directions. Please refer to Figure 5 , a blade 3-8 is fixedly installed at the lower end of the impeller 3-7. The blade 3-8 is located at the same horizontal position as the sewage suction port 3-10. The blades 3-8 of the two impellers 3-7 are installed in the opposite direction. The blade 3-8 is in a sickle shape and is vertically installed. The upper edge of the blade 3-8 is inclined outwards at an inclination angle. Preferably, the inclination angle is 60°, so that the disturbance of the impeller 3-7 can achieve the best collection and gathering effect on the manure.

[0086] For different forms of manure, the specific action principle of the suction feeding of the feeding component 3 is as follows:

[0087] For the bubble manure of pigs, the sewage collection tank contains a mixture of manure, urine, and water, with a moisture content of over 85% and good fluidity; after the transfer vehicle arrives at the sewage collection tank of the farm, the screw pump 3-1 at the lower part of the feeding component 3 is placed into the manure, and the outlet end of the sewage suction hose 3-2 is led into the mixing tank 2-1, and the screw pump motor 3-3 is directly started to drive the screw pump 3-1 to suck and discharge the manure into the mixing tank 2-1.

[0088] For dry-cleaned pig manure and cattle and sheep manure, the feces and urine are mixed in the sewage collection tank, with a water content of less than 85%, and poor fluidity. After the transport vehicle arrives at the sewage collection tank, the auger pump 3-1 at the lower part of the feeding component 3 is placed into the fecal sewage, and then the towing rod 3-5 is pushed down to move the baffle 3-4 downward, so that the lower edge of the baffle 3-4 is aligned with the edge of the sewage suction port 3-10, which is used to block and guide the fecal sewage, and the outlet end of the sewage suction hose 3-2 is led into 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 and are in the gathering function state, the fecal sewage is collected and gathered towards the sewage suction port 3-10. Then the auger pump motor 3-3 is started to drive the auger pump 3-1, and the auger pump 3-1 transports the fecal sewage into the mixing tank 2-1.

[0089] For poultry manure cleared from poultry houses, the fecal sewage in the sewage collection tank is generally in a semi-solid state, with a water content of less than 85%, poor fluidity, viscosity and accompanied by substances such as poultry feathers. After the transport vehicle arrives at the sewage collection tank, first add water to the fecal sewage, and the amount of added water is 20-30% of the amount of fecal sewage. Then pull up the towing rod 3-5 to move the baffle 3-4 upward, then place the feeding component 3 into the fecal sewage, and lead the outlet end of the sewage suction hose 3-2 into the mixing tank 2-1. After that, start the impeller motor 3-9 to drive the impeller 3-7 to rotate. The impeller 3-7 is in the mixing function state to mix the fecal sewage and water in the sewage collection tank, so as to improve the fluidity of the fecal sewage. After the impeller 3-7 rotates and mixes for 3-5 minutes, start the auger pump motor 3-3 to drive the auger pump 3-1 to transport the fecal sewage into the mixing tank 2-1.

[0090] Please refer to Figure 2, the chemical dosing component 5 includes a chemical dosing pump 5-1, a solenoid valve 5-3, a chemical dosing pipe 5-4, and a medicine barrel 5-5. The medicine barrel 5-5 is installed on the vehicle body component 1 and is used to store the medicine for conditioning the fecal sewage; the chemical dosing pump 5-1 is connected to the upper part of the medicine barrel 5-5, and the chemical dosing pump 5-1 communicates with the inlet and outlet of the mixing tank 2-1 through the solenoid valve 5-3 and the chemical dosing pipe 5-4; a manual stop valve 5-2 is connected to the pipeline between the chemical dosing pump 5-1 and the solenoid valve 5-3, which is used to manually switch the chemical dosing pipeline. The chemical dosing pump 5-1 and the solenoid valve 5-3 are respectively connected to the control system 4 and conduct signal transmission. According to the needs of fecal sewage 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 chemical dosing pump 5-1 after 1 minute, and pumps the medicine in the medicine barrel 5-5 into the fecal sewage in the mixing tank 2-1. The running duration of the chemical dosing pump 5-1 is controlled by the program and is adjustable. The running duration is determined according to the fecal sewage volume, the chemical dosing concentration, and the running frequency of the chemical dosing pump 5-1; after the running duration of the chemical dosing pump 5-1 reaches the set value, the chemical dosing pump 5-1 is closed, and the solenoid valve 5-3 is closed after 1 minute, thereby completing the automatic control chemical dosing program for conditioning the fecal sewage properties during the pretreatment process.

[0091] Please refer to 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 circulation pipe 6-4, an external pipe 6-6, and a water tank 6-9. The water tank 6-9 is fixedly arranged on the vehicle body component 1 and is used to store water. A slag cleaning port 6-5 is arranged at the lower part for regularly cleaning the sediment in the water tank 6-9 to prevent the sediment from entering the circulation pump 6-1 and the water circuit, causing pump wear or pipeline blockage. The circulation pump 6-1 is fixedly connected to the lower part of the water tank 6-9, or it can be an in-built pump, which is used to provide the power for transporting water. 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 pipe, and the free end can be connected to the inlet and outlet of the mixing tank 2-1 of the mixing component 2 for injecting water into the mixing tank 2-1. A jet port 6-8 is arranged at the end of the free end of the water supply pipe 6-3. One end of the circulation pipe 6-4 is connected to the water tank 6-9, and the other end is connected to the inner cavity of the mixing tank 2-1 for the recycling of the cleaning water, as shown in Figure 2 . The external pipe 6-6 is a flexible pipe. One end is connected to the water tank 6-9, and the other end is provided with an E-type quick connector 6-7 for connecting to an external water source to supplement water into the water tank 6-9.

[0092] When external water intake is required, use the E-type quick connector 6-7 to quickly connect to the external water source pipeline and fill the water tank 6-9. The operation is simple and fast. When adding water to the fecal sewage, open the manual valve 6-2, start the circulation pump 6-1, and add water to the fecal sewage through the water addition pipeline 6-3. After the water addition is completed, turn off the circulation pump 6-1. When it is necessary to clean the mixing tank 2-1 after the vehicle unloading is completed, manually remove the water addition pipeline 6-3, turn on the circulation pump 6-1, and flush the inside and outside of the mixing tank 2-1. The flushing water returns 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, remove the sundries through the slag cleaning port 6-5.

[0093] The control system 4 includes a control box body and its internal PLC control module, signal transmission device, control panel, etc. Before the fecal sewage transportation operation, according to the different forms of the fecal sewage to be processed, the operator inputs control parameters to the PLC control module through the control panel to form a built-in pretreatment program. Then, on the way of transportation, the control system 4 controls the automatic operation of the mixing component 2 and the chemical addition component 5 to complete the pretreatment of the transported fecal sewage, without causing an extra burden on the driver and not affecting driving safety.

[0094] For fecal sewage in different forms, the pretreatment programs for chemical addition and mixing of the control system 4 are different. The control logic is shown in Figure 7 .

[0095] For the pig manure of the flushing manure type, since it is a mixture of feces, urine and water, with a moisture content of more than 85%, good fluidity and good solid-liquid separation effect, no pretreatment is done during transportation.

[0096] For the pig manure of the dry cleaning manure type and cattle and sheep manure, which are mixtures of feces and urine with a moisture content of less than 85% and poor fluidity; during transportation, control the variable pump of the hydraulic system 2-3 in the mixing component 2 to make the mixing tank 2-1 rotate at a speed of 0.5 - 1 r / min, slowly stir the fecal sewage, and improve the speed of water separation in the fecal sewage through the mechanical force of stirring and the centrifugal force of rotation.

[0097] For the poultry manure in the farm, which is in a semi-solid state, with a water content of less than 85%, poor fluidity, viscous and accompanied by substances such as poultry feathers; during transportation, quicklime is manually added into the mixing tank 2-1, and 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 min for preliminary treatment of the manure. The addition amount is 2-4% of the manure volume. The high temperature and alkaline environment generated by the quicklime destroy the viscous substances on the manure surface, release the bound water and interstitial water, thereby improving the hydrophobicity of the manure. After that, the control system 4, according to the pretreatment program, sequentially opens the solenoid valve 5-3 on the medicine adding pipe 5-4 of the medicine adding component 5. After 1 min, the medicine adding pump 5-1 is started, and a cationic polyacrylamide solution (PAM) with a concentration of 1-5‰ is added to the manure in the mixing tank 2-1 to further improve the flocculation effect of the solids in the manure. After the conditioning drug addition amount reaches the predetermined value, the medicine adding pump 5-1 and the solenoid valve 5-3 are sequentially closed, and the pretreatment program is completed.

[0098] In summary, the comprehensive treatment and transportation method for manure described in the present invention includes the following steps. Please refer to Figure 8 :

[0099] Step 1, preparation stage - According to the form of the manure to be transported and processed, determine the pretreatment control parameters and input them into the control system 4, establish a pretreatment program for manure property conditioning, inject water into the water tank 6-9 through the water circulation component 6, and add the manure property conditioning drugs corresponding to the manure to the medicine barrel 5-5 of the medicine adding component 5;

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

[0101] Step 2, loading stage - According to the form of the manure to be transported, the manure is sucked into the mixing component 2 in different ways through the feeding component 3. After completion, the mixing tank 2-1 is sealed:

[0102] For waterlogged pig manure, the auger pump 3-1 at the lower part of the feeding component 3 is placed in the manure in the sewage collection tank, and the outlet end of the sewage suction hose 3-2 is led into the mixing tank 2-1. The auger pump motor 3-3 is directly started to drive the auger pump 3-1, and the manure is sucked and discharged into the mixing tank 2-1. After completion, the mixing tank 2-1 is sealed;

[0103] For dry-cleaned manure such as pig manure and cattle and sheep manure, first push down the towing rod 3-5 to align the lower edge of the baffle 3-4 with the edge of the sewage suction port 3-10, adjust the feeding component 3 to the gathering function state, then place the auger pump 3-1 at the lower part of the feeding component 3 into the manure in the sewage collection tank, and at the same time, insert the outlet end of the sewage suction hose 3-2 into the stirring tank 2-1. Then start the impeller motor 3-9 to drive the impeller 3-7 to rotate, and then start the auger pump motor 3-3 to drive the auger pump 3-1 to transport the manure to the stirring tank 2-1. After completion, seal the stirring tank 2-1.

[0104] For poultry manure, first add water to the manure through the water circulation component 6, and the water addition amount is 20-30% of the manure amount. Then pull up the towing rod 3-5 to move the baffle 3-4 upward, adjust the feeding component 3 to the stirring function state, then place the auger pump 3-1 at the lower part of the feeding component 3 into the manure in the sewage collection tank, and insert the outlet end of the sewage suction hose 3-2 into the stirring tank 2-1. After that, start the impeller motor 3-9 to drive the impeller 3-7 to rotate and stir the manure and water in the sewage collection tank. After stirring for 3-5 minutes, start the auger pump motor 3-3 to drive the auger pump 3-1 to transport the manure to the stirring tank 2-1. After completion, seal the stirring tank 2-1.

[0105] Step 3, transfer and pretreatment stage - The transporter drives onto the transfer route. At the same time, the control system 4 automatically controls the stirring component 2 and the chemical addition component 5 to operate in different programs according to the form of the transferred manure, realizing the automatic pretreatment of the transferred manure and completing the conditioning of the manure properties.

[0106] For water-immersed manure such as pig manure, no pretreatment is required.

[0107] For dry-cleaned manure such as pig manure and cattle and sheep manure, control the stirring tank 2-1 of the stirring component 2 to rotate at a speed of 0.5-1 r / min to stir the manure.

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

[0109] Step 4, discharging stage - After the transporter reaches the transfer end point and the pretreatment is completed, open the stirring component 2, and the stirring tank 2-1 discharges the manure after property conditioning treatment into the solid-liquid separation device.

[0110] Step 5, cleaning stage - after discharging, 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 flush the inside and outside of the mixing tank 2-1 to complete the cleaning of the mixing component 2; remove the sundries in the water tank 6-9 through the slag removal port 6-5.

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

[0112] Embodiment 1

[0113] In a large-scale chicken farm, sewage collection pools are distributed outside each chicken coop. The chicken manure has high viscosity and a water content of about 80%-85%, with poor fluidity. After the transport vehicle arrives at the sewage collection pool, put the feeding component 3 into the sewage collection pool. After the water circulation component 6 adds a small amount of water into the sewage collection pool, turn on the feeding component 3 to enter the mixing function state, and the impeller 3-7 mixes. After mixing for 5 minutes, push down the baffle 3-4, turn on the screw pump 3-1, and transport the manure and sewage into the mixing tank 2-1, and then seal it with the tank cover after completion. After completing the manure and sewage feeding, start the pretreatment program of the control system 4, and the transport vehicle drives for transportation. According to the settings of the pretreatment program, first add 2% quicklime to the manure and sewage and mix for 5 minutes, and the mixing component 2 works synchronously for mixing; then start the dosing component 5 and add cationic PAM (cationic polyacrylamide solution) with a concentration of 2‰ to the mixing tank 2-1 and mix for 20 minutes, with a mixing speed of 2-4 r / min. After the transport arrives at the destination, the pretreatment program ends, and the mixing component 2 discharges the pretreated manure and sewage into the high-efficiency solid-liquid separation device. The water content of the manure and sewage after solid-liquid separation can reach 65%-70%. After completing the discharging, start the water circulation component 6, turn on the circulation pump 6-1, hold the hose of the water supply pipeline 6-3, and flush the inside and outside of the mixing tank 2-1. The flushing water returns to the water tank 6-9 for temporary storage along the circulation pipeline 6-4. Regularly open the slag removal port 6-5 at the bottom of the water tank 6-9 to clean the sediment in the sedimentation tank to prevent the sediment from entering the circulation pump 6-1 and causing pump wear and blockage.

[0114] Embodiment 2

[0115] Large-scale pig farms adopt the dry and clear manure removal mode. There are sewage collection ponds distributed outside each pigsty. The moisture content of pig manure is low and it lacks fluidity. After the transporter arrives at the sewage collection pond, the feeding component 3 is placed into the sewage collection pond, and the baffle 3-4 is pushed down to enter the gathering function state. The impeller 3-7 in the feeding component 3 is turned on to collect and gather the manure and sewage, and then the screw pump 3-1 is turned on to transport the manure and sewage into the mixing tank 2-1. After that, it is sealed with the tank cover. After the manure and sewage feeding during transportation is completed, the mixing component 2 is started, and the mixing speed is 0.5-1 r / min. When it arrives at the destination, the mixing stops, and the pretreatment program ends. The mixing component 2 unloads the pretreated manure and sewage into the high-efficiency solid-liquid separation device. After separation, the moisture content of the manure and sewage can reach about 65%. After unloading, the water circulation component 6 is started, the circulation pump 6-1 is turned on, and the hose of the water supply pipeline 6-3 is held to flush the inside and outside of the mixing tank 2-1. The flushing water returns to the water tank 6-9 for temporary storage along the return pipeline 6-4. The slag cleaning port 6-5 at the bottom of the water tank 6-9 is regularly opened to clean the sediment in the slag collection tank to prevent the sediment from entering the circulation pump 6-1 and causing pump wear and blockage.

[0117] For farms below a certain scale, according to the type of large-scale farms, the type of manure and sewage, the operation steps are basically the same, but the transportation distance and duration increase.

[0118] The present invention is applicable to farms of various scales, including large-scale farms and farms below a certain scale; at the same time, the present invention is not only applicable to pig manure and poultry manure, but also applicable to various livestock manures, animal manures, organic solid wastes such as kitchen waste tailings, food processing wastes, etc. with various moisture contents, including cow manure, sheep manure, rabbit manure, mink manure, and kitchen waste treatment tailings.

[0119] The present invention transports the manure and sewage of farms in a sealed manner after mechanical feeding, and synchronously conducts automated pretreatment of the manure and sewage by category during transportation.
