Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a waste recycling device for cattle farms. Background Technology

[0002] With the rapid development of my country's animal husbandry, especially the shift towards intensive and large-scale dairy and beef cattle farming, the amount of waste generated by cattle farms has increased dramatically. This waste mainly consists of cattle manure, urine, leftover feed, and flushing wastewater, which is a difficult-to-treat high-concentration organic wastewater with high organic matter, ammonia nitrogen, suspended solids, and pathogenic bacteria content. If this waste is not treated promptly and effectively, it will not only occupy a large amount of land resources but also cause serious pollution to the surrounding soil, water bodies, and air (such as leading to eutrophication, breeding mosquitoes and flies, and producing foul odors), while also hindering the sustainable development of livestock farms.

[0003] Chinese patent CN114735858B discloses a solid-liquid separation device for catering wastewater, belonging to the technical field of catering wastewater treatment equipment. It includes a mobile support mechanism, a base plate, and a solid-liquid separation mechanism on the upper surface of the base plate. The solid-liquid separation mechanism includes a main tank, a wastewater collection tank at the bottom of the inner wall of the main tank, and an installation cavity in the side wall of the wastewater collection tank. A solidification pressurization mechanism is located near the main tank, including a secondary tank and a multi-stage quantitative dosing component located within the installation cavity. This invention achieves multiple dosing and pressurization of food residue during the solid-liquid separation process, with the amount of chemical added gradually increasing each time. This effectively prevents the food residue from spoiling and rotting in a short period. Furthermore, the pressurized food residue becomes material blocks, facilitating transportation, eliminating odors from spoilage, and retaining some nutritional value, making it suitable for use as fertilizer and feed. However, this device cannot perform multi-directional, multi-stage compression and dewatering of waste; the waste is only subjected to pressure from a single direction, resulting in low dewatering efficiency.

A conical column 716 is fitted with and fixedly connected to a spiral blade 717 on its outer side, and one end of the conical column 716 is fixedly connected to the output end of a drive motor 718.

[0021] The bottom of the feed pipe 74 extends into the interior of the first conical cylinder 71 and communicates with the first conical cylinder 71. The top of the discharge pipe 715 extends into the interior of the second conical cylinder 79 and communicates with the second conical cylinder 79. The discharge pipe 715 is provided in two sets. The first resistance bar 77 and the second resistance bar 712 are each provided in multiple sets. The extrusion device 78 is located between the first annular plate 76 and the second annular plate 713.

[0022] Two sets of tapered columns 716 are provided, which pass through the top cover 72 and the bottom cover 711 respectively. The two sets of tapered columns 716 are rotatably connected to the top cover 72 and the bottom cover 711 respectively through sealed bearings. Two sets of drive motors 718 are provided, which are fixedly connected to one side of the top cover 72 and the bottom cover 711 respectively.

[0023] The extrusion device 78 includes a movable plate 781. Both sides of the movable plate 781 are provided with storage grooves 782. Multiple sets of movable plates 781 are provided, and the multiple sets of movable plates 781 are slidably connected to each other by rubber sealing plates 783. An arc-shaped extrusion plate 784 is fixedly connected to one side of the movable plate 781. Water permeable holes 785 are evenly provided on the arc-shaped extrusion plate 784.

[0025] In operation, the operator discharges the waste to be processed into the first conical cylinder 71 through the feed pipe 74. Then, the drive motor 718 is turned on, causing the conical column 716 to rotate. The conical column 716 drives the spiral blades 717 to rotate. As the spiral blades 717 rotate, they push the waste downwards, squeezing it and expelling wastewater from the waste, which then flows out through the first filter hole 73. With the continuous rotation of the spiral blades 717, the waste is pushed into the extrusion device 78 for further dehydration. Subsequently, the waste... When the waste enters the second conical cylinder 79, the drive motor 718 on one side of the bottom cover 711 drives the spiral blades 717 to rotate, which pushes and squeezes the waste. Due to the setting of the first resistance bar 77 and the second resistance bar 712, the first resistance bar 77 and the second resistance bar 712 prevent the waste from rotating and generate a kneading effect until the waste is dehydrated and discharged from the discharge pipe 715. The wastewater is discharged into the treatment cylinder 1 from the second filter hole 710 and is promptly pumped away by the water pump 6. After repeated dehydration, the solid-liquid separation of the waste is more thorough.

[0026] When the waste enters the moving plate 781 from the first conical cylinder 71, the electric telescopic rod 786 is activated to push the moving plate 781. Multiple sets of moving plates 781 move towards the center at the same time. When the moving plates 781 move, they drive the rubber sealing plate 783 to slide into the storage groove 782. Multiple sets of moving plates 781 and rubber sealing plate 783 simultaneously squeeze the waste towards the center, squeezing the wastewater out of the water permeable hole 785. The waste is subjected to squeezing force from different directions, which further improves the dehydration efficiency.

[0027] For the second embodiment, please refer to...

[0031] In use, the water pump 6 is turned on to pump the wastewater into the discharge pipe 82, and then through the discharge pipe 82 into the outlet pipe 81. The wastewater is discharged through the outlet 83 on the outlet pipe 81. At the same time as turning on the water pump 6, the liquid pump 810 is turned on. The liquid pump 810 draws the flocculant inside the external storage mechanism into the delivery pipe 89. The flocculant enters the arc-shaped pipe 84 from the delivery pipe 89 through the delivery pipe 88 and the branch pipe 87, and then enters the diversion pipe 85. Finally, the flocculant is sprayed through the nozzle 86 into the water flowing out of the outlet 83, ensuring that every stream of wastewater entering the dosing cylinder 4 comes into contact with fresh flocculant the moment it enters the dosing cylinder 4.

[0032] When the wastewater falls vertically from the outlet 83, it carries gravitational potential energy. When this water flow and the flocculant impact the mixing grid 8112 below, it will generate violent hydraulic turbulence, which can disperse and mix the injected flocculant into the entire water body, avoiding the problem of local overdose or uneven mixing of the agent.
