Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a manure treatment system for pig farms. Background Technology

[0002] The manure treatment system of pig farms is an indispensable part of the sustainable development of modern animal husbandry. It is directly related to environmental protection, resource recycling, and the economic benefits and social image of the livestock industry. Its function is to effectively collect, classify, treat and utilize the large amount of manure and urine produced by pig farms, reduce environmental pollution and transform them into valuable by-products. Generally speaking, pig farm manure usually contains high concentrations of organic matter, nitrogen, phosphorus and microorganisms. If it is discharged directly without proper treatment, it will cause serious pollution to the environment.

[0003] Currently, the treatment of pig farm manure typically involves first collecting the manure, then separating it into solid and dry components. The solid portion is dried or mixed with straw, rice husks, etc., and then composted. Through the action of microorganisms, it is transformed into high-quality organic fertilizer for use in farmland, achieving nutrient recycling. The liquid portion is then fermented using anaerobic digestion to produce biogas (mainly methane), solving the manure treatment problem while obtaining clean energy. However, currently, the biogas fermentation of the separated liquid portion is mostly done by... When natural conditions permit, increasing the amount and intensity of sunlight in the biogas digester can raise the temperature inside, thereby promoting microbial activity and accelerating biogas fermentation in the liquid portion. However, in practice, this method still requires a relatively long time for the liquid portion to ferment, resulting in low efficiency. Although adding carbon sources (such as rice straw or corn stalks) or nitrogen sources (such as urea) to the liquid portion can also accelerate biogas fermentation, the liquid portion is generally in a sealed environment during biogas fermentation. Adding carbon or nitrogen sources manually is not only inconvenient but also prone to causing biogas leakage, which can harm the environment and people in the surrounding area. Summary of the Invention

[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0039] Example: Manure treatment system for pig farms, see [link / reference] Figures 1-10 As shown, it includes a treatment pool 1, a fixed frame 2, a rotating shaft 3, and a rotating column 4; the fixed frame 2 is connected to the upper side of the treatment pool 1; the rotating shaft 3 is rotatably connected to the inner side of the fixed frame 2 at intervals; the rotating column 4 is rotatably connected to the outer side of the rotating shaft 3, and the distance between two adjacent rotating columns 4 is greater than the distance between pig feet to prevent pig feet from getting stuck between two adjacent rotating columns 4. When raising pigs, the pigs are herded onto the rotating columns 4 for feeding. When the pigs defecate, the excreted feces can fall into the treatment pool 1 through the gaps between the rotating columns 4 for collection.

[0040] It also includes partitions 5, a feeding box 6, a discharge pipe 7, a sliding plate I 8, a sliding plate II 9, a corrugated pipe 10, a moving mechanism, a stirring and heating mechanism, a processing mechanism, and a sealing mechanism; the processing tank 1 is equipped with five partitions 5, namely one horizontal plate and four vertical plates. The horizontal plate is installed in the middle of the processing tank 1, with its left end connected to the left side wall of the processing tank 1 and its right end spaced a certain distance from the right side wall of the processing tank 1. The four vertical plates are connected at intervals to the bottom of the processing tank 1. The tops of the leftmost and rightmost vertical plates are connected to the bottom of the horizontal plate. The tops of the two middle vertical plates are spaced a certain distance from the bottom of the horizontal plate, and the two middle vertical plates have through holes. The rightmost vertical plate forms a manure collection space 51 between itself and the right side wall of the processing tank 1, so that... The feces that slide down the horizontal plate to the right fall into the feces collection space 51 for collection. Three sewage storage spaces 52 are formed between the four vertical plates, interconnected by through-holes in the vertical plates. These sewage storage spaces 52 collect the sewage after solid-liquid separation, allowing it to ferment and generate biogas. The biogas in the three sewage storage spaces 52 is interconnected through the distance between the tops of the two middle vertical plates and the bottom of the horizontal plate. Finally, a filtered water storage space 53 is formed between the leftmost vertical plate and the left side wall of the treatment tank 1, collecting the filtered sewage. Three feeding boxes 6 are spaced apart and installed at the rear of the treatment tank 1. The unit is equipped with a removable cover, and the feeding box 6 is used to add carbon or nitrogen sources; three discharge pipes 7 are connected to the inside of the treatment tank 1, with discharge ports spaced apart at the front of the bottom end of the discharge pipes 7, and the discharge ports are located within the filtered water storage space 53. The rear of the top end of the discharge pipes 7 is connected to the bottom end of the feeding box 6, so that the carbon or nitrogen sources in the feeding box 6 can fall into the discharge pipes 7; slide plate I 8 is slidably connected to the discharge pipes 7; slide plate II 9 is slidably connected to the discharge pipes 7, and slide plate II 9 is located in front of slide plate I 8; a corrugated pipe 10 is connected between slide plate I 8 and slide plate II 9, and the outer diameter of the corrugated pipe 10 is smaller than the inner diameter of the discharge pipe 7, so that the space between slide plate I 8 and slide plate II 9 can still store carbon or nitrogen sources after removing the corrugated pipe 10; a moving mechanism is used to drive... The sliding plate I8 moves so that the sliding plate I8, corrugated pipe 10 and sliding plate II9 can bring the carbon source or nitrogen source into the discharge port of the discharge pipe 7, so that the carbon source or nitrogen source falls into the sewage in the filtered water storage space 53 through the discharge port of the discharge pipe 7, thereby accelerating the biogas fermentation of the sewage; the stirring and heating mechanism is used to stir the manure and sewage in the manure collection space 51 and the filtered water storage space 53 and heat the sewage, thereby accelerating the biogas fermentation of manure and sewage; the treatment mechanism is used to separate the manure into solid and liquid and filter the separated sewage; the sealing mechanism is used to seal the manure and sewage in the manure collection space 51 and the sewage storage space 52 to prevent the leakage of biogas formed by the fermentation of manure and sewage.

[0041] See Figure 5 As shown, the moving mechanism includes a geared motor 11 and a lead screw I 12; the geared motor 11 is connected to the rear end of the discharge pipe 7; the lead screw I 12 is rotatably connected to the eccentric part inside the discharge pipe 7, and the rear end of the lead screw I 12 is connected to the output shaft of the geared motor 11 so that the geared motor 11 can drive the lead screw I 12 to rotate, and the lead screw I 12 is threaded through the slide plate I 8 so that the slide plate I 8 can be moved when the lead screw I 12 rotates, the lead screw I 12 slides through the slide plate II 9, and the lead screw I 12 passes through the bellows 10 without contact. By rotatably setting the lead screw I 12 to the eccentric part inside the discharge pipe 7, the lead screw I 12 and the bellows 10 can be prevented from being located directly below the center of the feeding box 6, thereby avoiding the lead screw I 12 and the bellows 10 from blocking the carbon source or nitrogen source falling into the feeding box 6.

[0042] See Figure 6 As shown, the stirring and heating mechanism includes a servo motor 13, a stirring frame 14, and a heating rod 15. Five servo motors 13 are installed on the rear side of the treatment tank 1. The output shafts of the five servo motors 13 are all connected to stirring frames 14. The two stirring frames 14 on the right are located in the fecal collection space 51 so that the two stirring frames 14 on the right can stir the fecal matter in the fecal collection space 51 when they rotate. The remaining three stirring frames 14 are located in the sewage storage space 52 so that the remaining three stirring frames 14 can stir the sewage in the sewage storage space 52 when they rotate. A heating rod 15 is installed on each of the three stirring frames 14 in the sewage storage space 52 so that the heating rod 15 can heat the sewage in the sewage storage space 52.

[0043] See Figure 7 and Figure 8As shown, the treatment unit includes a collection tank 16, a solid-liquid separator 17, a sludge pump 171, a biogas discharge pipe 19, and a wastewater purifier 20. The collection tank 16 is connected to the front of the treatment tank 1. The solid-liquid separator 17 is installed on the upper right side of the collection tank 16. The solid-liquid separator 17 is used to separate the solid and liquid of the fecal wastewater, and the liquid discharge end of the solid-liquid separator 17 is connected to the wastewater storage space 52 so that the solid-liquid separator 17 can discharge the separated wastewater into the wastewater storage space 52. The sludge pump 171 is installed... The solid-liquid separator 17 is installed at the bottom of the treatment tank 1, and the sludge pump 171 is located within the fecal collection space 51. The feed end of the solid-liquid separator 17 is connected to the sludge pump 171, so that the sludge pump 171 can pump the fecal matter in the fecal collection space 51 into the solid-liquid separator 17 for solid-liquid separation. A solid collection space 18 is provided on the right front side of the collection tank 16, and the solid discharge end of the solid-liquid separator 17 is located within the solid collection space 18, so that the solid-liquid separator 17 can discharge the separated fecal matter into the solid collection space 18 for further processing. The biogas collection system is as follows: A biogas discharge pipe 19 is installed on the upper front of the treatment tank 1, and the two inlet ends of the biogas discharge pipe 19 are connected to the manure collection space 51 and the middle sewage storage space 52, respectively, so that the biogas in the manure collection space 51 and the sewage storage space 52 can be discharged through the biogas discharge pipe 19; A sewage purifier 20 is installed on the left side of the collection tank 16. The sewage purifier 20 is used to filter sewage, and the inlet end of the sewage purifier 20 is connected to the leftmost sewage storage space 52, so that the sewage in the sewage storage space 52 can be drawn into it by the sewage purifier 20. The outlet end of the sewage purifier 20 is connected to the filtered water storage space 53, so that the sewage purifier 20 can discharge the filtered sewage into the filtered water storage space 53 for storage; A waste residue collection space 21 is provided on the left front side of the collection tank 16. The slag discharge port of the sewage purifier 20 is located in the waste residue collection space 21, so that the sewage purifier 20 can discharge the waste residue filtered from the sewage into the waste residue collection space 21 for collection.

[0044] See Figure 9 and Figure 10As shown, the sealing mechanism includes a belt conveyor 22, a rotating rod 23, a guide column 24, an arc plate 25, and a gear set 26. The belt conveyor 22 is installed inside the treatment tank 1. The right end of the horizontal plate in the partition 5 presses against the right side of the bottom end of the belt of the belt conveyor 22, so that the right side of the bottom end of the belt of the belt conveyor 22 is tightly pressed against the right end of the horizontal plate in the partition 5, thereby blocking the outside air at this contact point. The rotating rod 23 is rotatably connected to the right side inside the treatment tank 1. The guide column 24 is connected to the rotating rod 23. The leftmost end of the guide column 24 presses against the belt of the belt conveyor 22, so that the right end of the belt of the belt conveyor 22 is tightly pressed against the leftmost end of the guide column 24, thereby blocking the outside air at this contact point. The outside air is blocked; the arc plate 25 is connected to the right side of the treatment tank 1, and the guide column 24 is in contact with the inner wall of the arc plate 25, thereby blocking the outside air at this contact point. In this way, the belt conveyor 22, the guide column 24 and the arc plate 25 are used to seal the manure collection space 51 and the sewage storage space 52 to prevent biogas leakage in the manure collection space 51 and the sewage storage space 52; the gear set 26 consists of two full gears, which are respectively installed on the rotating rod 23 and the drive shaft of the belt conveyor 22, and the two full gears mesh with each other so that the belt conveyor 22 can drive the rotating rod 23 to rotate through the gear set 26 when it is running.

[0045] In use, a fence can be installed on the fixed frame 2, and then pigs can be herded onto the rotating columns 4 for feeding. When the pigs defecate, the excreted manure can fall into the treatment tank 1 through the gaps between the rotating columns 4. When the manure in the treatment tank 1 falls onto the belt of the belt conveyor 22, the belt conveyor 22 will transport the manure to the right to the guide column 24. During this period, the belt conveyor 22 will use the transmission of the gear set 26 to drive the rotating rod 23 and the guide column 24 to rotate, so that the guide column 24 will guide the manure into the manure collection space 51 for collection, so that the manure can undergo biogas fermentation in the manure collection space 51. During this period, the servo motor 13 drives the stirring frame 14 to rotate, so that the stirring frame 14 stirs the manure in the manure collection space 51, thereby accelerating the biogas fermentation of the manure.

[0046] Subsequently, the manure in the manure collection space 51 is periodically pumped into the solid-liquid separator 17 by the sludge pump 171. The solid-liquid separator 17 then separates the manure into solid and liquid components, allowing the separated wastewater to flow into the wastewater storage space 52, while the separated manure falls into the solid collection space 18 for collection. This allows the farmers to remove the manure from the solid collection space 18 and convert it into high-quality organic fertilizer. During this process, the servo motor 13 drives the stirring frame 14 to rotate, causing the stirring frame 14 to agitate the wastewater in the wastewater storage space 52, thereby accelerating the process. Biogas fermentation is carried out, and the sewage in the sewage storage space 52 is heated by the heating rod 15 to raise the temperature to a suitable temperature for biogas fermentation, thereby accelerating the biogas fermentation process. Then, the cover of the feeding box 6 is removed, and a carbon source or nitrogen source is added to the feeding box 6, causing the carbon source or nitrogen source to fall into the discharge pipe 7 and be positioned between the sliding plate I8 and the sliding plate II9. Then, the cover of the feeding box 6 is replaced, and the screw I12 is driven to rotate by the reduction motor 11, causing the sliding plate I8 to move forward, thereby pushing the sliding plate I8... The carbon or nitrogen source, corrugated pipe 10, and slide plate II 9 move forward, causing the carbon or nitrogen source to move within the sealed space between slide plate I 8 and slide plate II 9. When the carbon or nitrogen source reaches the outlet of the discharge pipe 7, it falls downwards into the wastewater storage space 52, thus maintaining a suitable carbon-to-nitrogen ratio in the wastewater and improving the gasification efficiency. When slide plate II 9 contacts the innermost tip of the discharge pipe 7, the innermost tip of the discharge pipe 7 blocks slide plate II 9 from moving forward. At this time, slide plate I 8 continues to push the carbon or nitrogen source and the corrugated pipe... When the bellows 10 moves forward, it is compressed until the slide plate I8 pushes all the carbon or nitrogen source into the discharge port of the discharge pipe 7 and drops it. Then, the screw I12 is reversed and reset by the reduction motor 11, so that the slide plate I8 moves backward and resets. During this period, the bellows 10 gradually returns to its original state. After the bellows 10 returns to its original state, the slide plate I8 will pull the bellows 10 and the slide plate II9 to move backward and reset. In this way, the carbon or nitrogen source can be automatically added to the sewage in a closed environment. It is not only simple to operate and saves time and effort, but also prevents the biogas in the sewage storage space 52 from leaking.

[0047] Then, the sewage in the sewage storage space 52 is periodically extracted by the sewage purifier 20 and filtered by the sewage purifier 20. The filtered sewage is then discharged into the filtered water storage space 53 for storage so that the filtered water can be reused later, thereby saving water resources. The waste residue filtered from the sewage is discharged into the waste residue collection space 21 for collection so that the breeding personnel can centrally process the waste residue from the waste residue collection space 21 later.

[0048] When it is necessary to discharge the biogas in the manure collection space 51 and the sewage storage space 52, the biogas can be discharged through the biogas discharge pipe 19.

[0049] See Figure 11 and Figure 12 As shown, it also includes a cleaning mechanism, which includes a water pump 27, an electric three-way valve 28, a connecting pipe II 29, and a spray pipe I 30. The water pump 27 is connected to the bottom left rear side of the treatment tank 1, and the water inlet of the water pump 27 is connected to the filtered water storage space 53. The electric three-way valve 28 is installed on the water pump 27 and has three ports: upper, right, and lower. The water outlet of the water pump 27 is connected to the lower port of the electric three-way valve 28. One end of the connecting pipe II 29 is connected to the right port of the electric three-way valve 28, and the other end of the connecting pipe II 29 is connected to two spray pipes I 30. The nozzle of the right spray pipe I 30 faces the guide column 24 so that the water sprayed from the right spray pipe I 30 can clean the guide column 24. The nozzle of the left spray pipe I 30 faces the bottom of the belt of the belt conveyor 22 so that the water sprayed from the left spray pipe I 30 can clean the belt of the belt conveyor 22.

[0050] In use, the electric three-way valve 28 can be controlled to connect the lower port with the right port. Then, the water pump 27 draws the filtered water from the filtered water storage space 53 into the electric three-way valve 28, connecting pipe II 29 and spray pipe I 30. The spray pipe I 30 sprays the filtered water onto the feed column 24 and the belt of the belt conveyor 22, thereby rinsing the feed column 24 and the belt of the belt conveyor 22. This not only makes it easier for farmers to clean the feed column 24 and the belt of the belt conveyor 22 to prevent a large amount of manure from adhering to the belt, but also allows the filtered water to be reused.

[0051] See Figures 13-18As shown, it also includes a rotating mechanism, which includes an electric push rod I 31, a rack 32, an electric push rod II 33, a connecting plate 34, a T-block 35, and a torsion spring 36; the upper parts of both the front and rear sides of the treatment tank 1 are connected to the electric push rod I 31; the rack 32 is connected to the telescopic rod of the electric push rod I 31; the front and rear ends of the rotating shaft 3 are both provided with toothed grooves, the front rack 32 meshes with the toothed groove on the front side of the rotating shaft 3, and the rear rack 32 meshes with the toothed groove on the rear side of the rotating shaft 3; the four electric push rods II 33 are symmetrically arranged. It is placed inside the fixed frame 2; a connecting plate 34 is connected between the telescopic rods of the two electric push rods II 33 on the front side, and a connecting plate 34 is also connected between the telescopic rods of the two electric push rods II 33 on the rear side; movable grooves 341 are opened at both the front and rear ends of the rotating column 4; T-shaped blocks 35 are slidably connected at both the front and rear ends of the rotating shaft 3, the T-shaped block 35 on the front side is rotatably connected to the connecting plate 34 on the front side, and the T-shaped block 35 on the rear side is rotatably connected to the connecting plate 34 on the rear side; the two ends of the torsion spring 36 are respectively connected to the rotating shaft 3 and the rotating column 4.

[0052] See Figures 19-21 As shown, it also includes a rinsing mechanism, which includes a drive motor 37, a lead screw II 38, a nozzle II 39, a connecting block 40, a double-layer hollow winding drum 41, a spring 42, and a connecting pipe I 43. The drive motor 37 is installed inside the treatment tank 1. The lead screw II 38 is connected to the output shaft of the drive motor 37. The nozzle II 39 is threadedly connected to the lead screw II 38 and is slidably connected to the treatment tank 1 so that when the drive motor 37 drives the lead screw II 38 to rotate, it can drive the nozzle II 39 to move. The nozzle II 39 is located directly below the rotating column 4, and the nozzle II 39 sprays... The nozzle of the nozzle II 39 faces the rotating column 4 so that the nozzle can concentrate water and spray it onto the rotating column 4 for rinsing; the two connecting blocks 40 are distributed vertically and connected to the inner wall of the treatment tank 1; the double-layer hollow winding drum 41 is rotatably connected between the two connecting blocks 40, and the bottom end of the double-layer hollow winding drum 41 is connected to the upper port of the electric three-way valve 28; the two ends of the spring 42 are respectively connected to the bottom end of the double-layer hollow winding drum 41 and the connecting block 40 on the lower side; two connecting pipes I 43 are wound on the double-layer hollow winding drum 41, and the two ends of the connecting pipes I 43 are respectively connected to the double-layer hollow winding drum 41 and the nozzle II 39.

[0053] In use, the connecting plate 34 can be moved to the side furthest from each other by the electric push rod II 33, thereby moving the T-block 35 to the side furthest from each other, so that the T-block 35 enters the movable groove 341 in the rotating column 4. Then, the rack 32 is moved to the right by the electric push rod I 31 (the rack 32 is moved to the left for the next use, and this process is repeated). The rack 32 drives the rotating shaft 3 and the T-block 35 to rotate 180 degrees. If the pig is not on the rotating column 4, the rotating shaft 3 will drive the rotating column 4 to rotate 180 degrees synchronously by the torsion spring 36. If the pig is on the rotating column 4, the rotating shaft 3 does not need to drive the rotating column 4 to rotate synchronously at that point by the torsion spring 36. The rotation is turned 180 degrees, causing the torsion spring 36 to deform. The pig is then driven away from the rotating column 4. After the pig leaves the rotating column 4, the torsion spring 36 returns to its original state, causing the rotating column 4 to rotate 180 degrees. Then, the electric push rod II 33 drives the connecting plate 34 to move closer together to reset, thereby moving the T-block 35 closer together to reset. This causes the T-block 35 to leave the movable groove 341 inside the rotating column 4, thus locking the rotating column 4 (because the rack 32 jams the rotating shaft 3, the rotating shaft 3 cannot rotate, thus preventing the T-block 35 and the rotating column 4 from rotating), preventing the rotating column 4 from rotating and affecting the pig's entry. After the operation, the electric three-way valve 28 is controlled to connect the lower port to the upper port. Then, the water pump 27 draws the filtered water from the filtered water storage space 53 into the electric three-way valve 28, the double-layer hollow winding drum 41, the connecting pipe I 43, and the spray pipe II 39. This causes the nozzle of the spray pipe II 39 to concentrate the filtered water onto the bottom and sides of the rotating column 4, thereby rinsing the bottom and sides of the rotating column 4. Then, the drive motor 37 drives the screw II 38 to rotate intermittently in both directions, causing the spray pipe II 39 to move back and forth. This allows the filtered water sprayed from the spray pipe II 39 to rinse the bottom and sides of the entire rotating column 4, making it convenient for the aquaculture personnel to rinse the bottom and sides of the rotating column 4. The process involves washing the pigs, and by setting the nozzles on the spray pipe II 39 to face the rotating column 4, it avoids spraying large amounts of filtered water onto the pigs, preventing them from getting cold and becoming sick. During this process, when the spray pipe II 39 moves back and forth, it pulls or releases the connecting pipe I 43. When the spray pipe II 39 pulls the connecting pipe I 43, the connecting pipe I 43 pulls the double-layer hollow winding drum 41 to rotate, and the spring 42 deforms. When the spray pipe II 39 releases the connecting pipe I 43, the spring 42 returns to its original shape, and the spring 42 drives the double-layer hollow winding drum 41 to reverse and reset, so that the double-layer hollow winding drum 41 winds up the connecting pipe I 43 to prevent the connecting pipe I 43 from scattering on the ground.
