Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for cleaning livestock manure. Background Technology

[0002] As my country's livestock farming industry transforms towards large-scale and intensive operations, the treatment of the large amount of manure generated daily by farms has become a major challenge in the environmental protection field. Livestock and poultry manure is extremely complex, containing a large amount of fine fibers, undigested proteins, oils, and viscous colloids. Before entering the subsequent biochemical treatment unit, it is necessary to remove large particulate suspended solids through a solid-liquid separation process to reduce the organic load and realize the resource utilization of manure residue.

[0003] However, most of the mainstream preliminary treatment equipment on the market currently uses static filter technology (such as fixed bar screens, static inclined screens, or gravity sedimentation tanks). When actually treating high-viscosity substances like livestock manure, this existing technology reveals the following technical shortcomings: Because static filters lack an active cleaning mechanism, sticky fecal sludge will quickly be physically adsorbed and accumulated on the surface of the mesh after contacting the filter under the action of gravity or water flow. As filtration proceeds, the fecal sludge layer will evolve into a dense "mud cake", completely blocking the outflow path of the filtrate, resulting in an exponential decrease in filtration efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wastewater treatment device for cleaning livestock manure, which can perform preliminary solid-liquid separation on the initially sticky manure residue while reducing the probability of clogging.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This type of sewage treatment device for cleaning livestock manure, by setting up a first screw conveyor and a second screw conveyor in conjunction with a funnel-shaped mesh, can generate a continuous downward squeezing force on the tangentially entering sewage. This active mechanical propulsion method not only forces solid-liquid separation, but also effectively avoids the physical adsorption of sticky manure residue on the mesh surface through the rotational shearing action of the screw surface, greatly reducing the probability of filter clogging. This wastewater treatment device for cleaning livestock manure utilizes the preset elastic force of the first spring and the second column to form an adaptive unloading structure. When solid manure accumulates to a certain weight, it automatically overcomes the elastic force and is discharged. After discharge, it immediately resets and seals. This design of "blocking manure with manure and discharging under constant pressure" not only ensures that the manure is fully mechanically pressed and dehydrated before discharge, reducing the moisture content of the waste residue, but also realizes unmanned automatic circulation operation of the equipment. This wastewater treatment device for cleaning livestock manure utilizes the residual pressure of wastewater to drive an impeller to generate electricity. This not only feeds back the power to the system but also prevents scaling in the pipes through the generated electrostatic field. At the same time, by using a force-bearing component to sense the flow rate and automatically adjust the valve of the fourth pipe, it achieves adaptive dosing of "more medicine when there is more water and less medicine when there is less water," ensuring the scientific nature of the drug ratio and the stability of the treatment effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1-12 A wastewater treatment device for cleaning livestock manure, comprising: The separation mechanism 1 has a second cavity 101 inside which is capable of separating livestock manure into solid and liquid components. The unloading mechanism 2 can discharge the solid feces to the outside of the second cavity 101 after the solid feces have accumulated to a certain extent in the second cavity 101. The unloading mechanism 2 can also reseal the second cavity 101 after the solid feces have been discharged to the outside of the second cavity 101. The thrust mechanism 6 can drive the solid feces separated in the second cavity 101 to deposit at the bottom of the second cavity 101, and the thrust mechanism 6 can also drive the solid feces that have accumulated to a certain extent in the second cavity 101 to be discharged to the outside of the second cavity 101. The power mechanism 3 can drive the thrust mechanism 6 to drive the solid feces separated in the second cavity 101 to be deposited at the bottom of the second cavity 101, and the power mechanism 3 can also drive the thrust mechanism 6 to discharge the solid feces that have accumulated to a certain extent in the second cavity 101 to the outside of the second cavity 101. It also includes a power recovery mechanism 4, through which the separated wastewater in the second chamber 101 can generate electricity, and the power recovery mechanism 4 can change the power generation power according to the flow rate of the separated wastewater in the second chamber 101. The dosing unit 5 is capable of adding chemicals to the wastewater discharged into the power recovery unit 4, and the dosing unit 5 can also change the dosing amount according to the flow rate of the wastewater in the power recovery unit 4.

[0020] Furthermore, in order to enable the separation mechanism 1 to separate livestock manure into solid and liquid components, as a preferred embodiment of the present invention, the separation mechanism 1 includes a housing 12, a filter assembly 13, and a plurality of first columns 11. The upper ends of the plurality of first columns 11 are fixedly connected to the lower ends of the housing 12. The second cavity 101 is located inside the housing 12. The filter assembly 13 is located inside the second cavity 101 of the housing 12. The lower ends of the plurality of first columns 11 are all connected to the unloading mechanism 2. More specifically, the outer shell 12 includes a first shell 121, a second shell 122, a third shell 123, a first tube 124, and a second tube 125. The upper ends of a plurality of first columns 11 are fixedly connected to the lower ends of the first shell 121. The upper ends of the first shell 121 are fixedly connected to the lower ends of the second shell 122. The upper ends of the second shell 122 are fixedly connected to the lower ends of the third shell 123. One side of the upper end of the third shell 123 is fixedly connected to one end of the second tube 125. One side of the lower end of the first shell 121 is fixedly connected to one end of the first tube 124. The other end of the first tube 124 is connected to the power recovery mechanism 4. More specifically, the filter assembly 13 includes a fifth tube 131, a mesh 132, and a ring 133. The outer wall of the ring 133 is fixedly connected to the upper end of the second cavity 101. The bottom surface of the ring 133 is connected to the upper end of the mesh 132. The lower end of the mesh 132 is fixedly connected to the upper end of the fifth tube 131. The lower end of the fifth tube 131 passes through the middle of the first housing 121 and is fixedly connected to the through point of the first housing 121. The inner wall of the fifth tube 131 is connected to the unloading mechanism 2. More specifically, the cross-section of the mesh 132 on the first surface is funnel-shaped, and the first surface is perpendicular to the horizontal plane; Specifically, such as Figures 1-5 As shown, firstly, the end of the second pipe 125 furthest from the third housing 123 is connected to an external sewage source (such as a sewage pipe in the breeding room). (Currently, sewage discharge from breeding rooms is mostly driven by pumps or other equipment, which is existing technology and will not be described in detail here.) When the wastewater is first processed, it first enters the third housing 123 through the second pipe 125. Since the second pipe 125 is located on one side of the third housing 123, the wastewater entering the third housing 123 enters the funnel-shaped mesh 132 tangentially. Also because of the tangential entry, the wastewater will form a vortex. At this time, the solid feces trapped in the wastewater will be blocked by the mesh 132, while the finer wastewater will pass through the mesh of the mesh 132 and then be discharged from the first pipe 124 of the first housing 121 into the power recovery mechanism 4 for subsequent steps. Furthermore, as the amount of solid feces inside the net body 132 increases, the weight accumulated on the surface of the unloading mechanism 2 increases until the weight of the feces reaches the maximum support value of the unloading mechanism 2. Then the unloading mechanism 2 automatically opens, and the accumulated feces can be discharged to the outside. After the feces are discharged, the weight above the unloading mechanism 2 becomes lighter, and the unloading mechanism 2 resets again, and then the above steps are repeated.

[0021] Furthermore, in order to enable the unloading mechanism 2 to discharge the solid feces to the outside of the second cavity 101 after the solid feces have accumulated to a certain extent in the second cavity 101, and to reseal the second cavity 101 after the solid feces have been discharged to the outside of the second cavity 101, as a preferred embodiment of the present invention, the unloading mechanism 2 includes a first frame 21, a shielding member 22, a second column 23, a first spring 24, and a telescopic rod 25. The outer wall of the first frame 21 is fixedly connected to the lower ends of several first columns 11. The upper surface of the middle part of the first frame 21 is fixedly connected to the lower ends of the shielding member 22, the first spring 24, and the telescopic rod 25. The upper ends of the shielding member 22, the first spring 24, and the telescopic rod 25 are fixedly connected to the lower ends of the second column 23. The upper end of the second column 23 penetrates into the interior of the fifth tube 131, and the outer wall of the second column 23 is slidably connected to the inner wall of the fifth tube 131. More specifically, the shield 22 is an organ pipe, and the shield 22 is located outside the first spring 24 and the telescopic rod 25; More specifically, the end of the second column 23 located inside the fifth tube 131 is conical; Specifically, such as Figures 2-4 as well as Figure 8 and Figure 9 As shown, initially, as solid residues continue to accumulate, the vertical load applied to the top of the second column 23 increases daily, and the thrust mechanism 6 continuously drives it downwards. Once the total load exceeds the elastic threshold of the first spring 24, the column, along with the deposits, settles below the port of the fifth tube 131, opening the drainage passage between the inner cavity and the outside, and the solid waste slides down and is discharged along the conical guide surface.

[0022] In this alternating instant, the bottom edge of the first spiral conveyor 61 continuously performs high-speed rotary cutting on the cone apex area at extremely close range, forcibly breaking up the surrounding flocculent colloids. As the material is discharged and the elastic backlash occurs, the second column 23 rapidly rebounds and retracts. During this upward stroke, the annular hard scraping blade on the inner edge of the fifth tube 131 acts like a microscopic peeler, directly removing the sticky proteins and lipids that attempt to adhere to the side of the column. Meanwhile, the remaining trace amounts of liquid phase fibers are forcibly squeezed and guided to the lower end for freeing through the slag discharge micro-grooves on the side wall. The multi-dimensional mechanical shearing and surface anti-adhesion mechanism work together to destroy the physical link of foreign matter clamping on the sealing surface, giving the system the inevitability of smooth reciprocating operation in harsh two-phase flow environments.

[0023] Furthermore, in order to enable the thrust mechanism 6 to drive the solid feces separated in the second cavity 101 to deposit at the bottom of the second cavity 101, and the thrust mechanism 6 to also drive the solid feces accumulated in the second cavity 101 to be discharged to the outside of the second cavity 101, as a preferred embodiment of the present invention, the thrust mechanism 6 includes a first spiral conveyor 61 and a plurality of second spiral conveyors 62. The main bodies of the first spiral conveyor 61 and the plurality of second spiral conveyors 62 are all located inside the mesh body 132. The upper ends of the first spiral conveyor 61 and the plurality of second spiral conveyors 62 all penetrate to the outside of the third housing 123 and are connected to the power mechanism 3. The first spiral conveyor 61 is located between the plurality of second spiral conveyors 62. The lower end of the first spiral conveyor 61 faces the center of the fifth tube 131. The spiral surfaces of the plurality of second spiral conveyors 62 abut against the inner sidewall of the mesh body 132. Specifically, such as Figure 3 , Figure 6 and Figure 7 As shown, during use, as sewage enters the net body 132, the first screw conveyor 61 and several second screw conveyors 62 will continuously rotate due to the drive of the power mechanism 3, thus continuously providing a downward thrust to the sewage entering the net body 132. Since liquid sewage will preferentially leak out from the mesh of the net body 132, more and more solid feces will be pushed into the fifth tube body 131 by the first screw conveyor 61 and several second screw conveyors 62 until the total weight of these feces reaches the maximum elastic force of the first spring 24, at which point the bottom opening of the fifth tube body 131 is opened, thereby discharging these feces.

[0024] Furthermore, in order for the power mechanism 3 to drive the thrust mechanism 6 to deposit the solid feces separated in the second cavity 101 at the bottom of the second cavity 101, and for the power mechanism 3 to also drive the thrust mechanism 6 to discharge the solid feces accumulated in the second cavity 101 to the outside of the second cavity 101, as a preferred embodiment of the present invention, the power mechanism 3 includes a transmission motor 31, a second frame 32, a first transmission assembly 33, a plurality of second transmission assemblies 34, and a plurality of first rods 35. The lower ends of the plurality of first rods 35 are all fixedly connected to the upper surface of the third housing 123, and the upper ends of the plurality of first rods 35 are all fixedly connected to the upper surface of the second housing 123. The frame 32 is fixedly connected. The upper surface of the middle part of the second frame 32 is fixedly connected to the outer wall of the drive motor 31. The output shaft of the drive motor 31 passes through the second frame 32 and is connected to the upper surface of the first transmission assembly 33. The bottom surface of the first transmission assembly 33 is fixedly connected to the upper end of the first screw conveyor 61. The outer wall of the first transmission assembly 33 is connected to several second transmission assemblies 34. The other end of several second transmission assemblies 34 is connected to the upper end of several second screw conveyors 62 respectively. The second frame 32 is located outside the first transmission assembly 33. The output shaft of the drive motor 31 is rotatably connected to the through-hole of the second frame 32 through the first bearing. More specifically, the first transmission assembly 33 includes a gear ring 331, a third frame 332, and a plurality of spur gears 333. The upper surface of the middle part of the third frame 332 is fixedly connected to the output shaft of the transmission motor 31, the bottom surface of the middle part of the third frame 332 is fixedly connected to the upper end of the first screw conveyor 61, the outer wall of the third frame 332 is fixedly connected to the inner wall of the gear ring 331, the gear ring 331 meshes with the plurality of spur gears 333, and the plurality of spur gears 333 are respectively connected to a plurality of second transmission assemblies 34. More specifically, the second transmission assembly 34 includes a first bevel gear 341, a second bevel gear 342, and a second rod 343. The lower end of the second rod 343 is rotatably connected to the third housing 123 via a first bearing. The upper end of the second rod 343 passes through the spur gear 333 and the first bevel gear 341 and is fixedly connected to both the spur gear 333 and the first bevel gear 341. The second bevel gear 342 is sleeved on and fixedly connected to the upper end of the second screw conveyor 62. The first bevel gear 341 and the second bevel gear 342 mesh. Specifically, such as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, when the separation of solid and liquid feces begins, the drive motor 31 is turned on first. The output shaft of the drive motor 31 drives the third frame 332 to rotate. Then the third frame 332 drives the first screw conveyor 61 and the toothed ring 331 to rotate synchronously. The rotation of the gear ring 331 will cause several spur gears 333 to rotate together. The rotation of the spur gears 333 will cause the first bevel gear 341, which is also connected to the second rod 343, to rotate. Then the first bevel gear 341 will cause the second bevel gear 342 to rotate. The second bevel gear 342 will cause the second screw conveyor 62 to rotate. As the first screw conveyor 61 and the second screw conveyor 62 rotate, the solid feces entering the net body 132 will be pushed into the fifth tube body 131 as mentioned above.

[0025] Furthermore, in order to enable the separated wastewater in the second chamber 101 to generate electricity through the power recovery mechanism 4, and for the power recovery mechanism 4 to change the power generation power according to the flow rate of the separated wastewater in the second chamber 101, as a preferred embodiment of the present invention, the power recovery mechanism 4 includes a generator 41, a fourth housing 42, a third pipe 43, an impeller 44, and a third rod 45. One side of the upper end of the fourth housing 42 is fixedly connected to the end of the first pipe 124 away from the first housing 121. The lower end of the fourth housing 42 is fixedly connected to one end of the third pipe 43. The other end of the third pipe 43 is connected to the dosing mechanism 5. The impeller 44 is located inside the upper end of the fourth housing 42. The upper surface of the impeller 44 is fixedly connected to one end of the third rod 45. The upper end of the third rod 45 extends through to the outside of the fourth housing 42 and is fixedly connected to the input end of the generator 41. More specifically, generator 41 is electrically connected to drive motor 31 via wiring harness; More specifically, a metal ring electrode is provided between the outer structural layer and the inner insulating and anti-corrosion layer of the second housing 122. The generator 41 outputs DC high voltage through the rectifier module. The positive output terminal of the generator 41 is grounded to the fourth housing 42 and forms zero potential contact with the sewage inside the fourth housing 42 through the conductive flange. The negative output terminal of the generator 41 passes through the insulating sleeve and is electrically connected to the metal ring electrode that is coaxially sealed and embedded in the second housing 122. Specifically, such as Figure 3 , Figure 4 and Figure 10 As shown, when the preliminarily separated sewage enters the fourth housing 42 from the first pipe 124, and because the first pipe 124 is located on one side of the fourth housing 42, the sewage flowing out from the first pipe 124 forms a "tangent angle" with the impeller 44 located in the fourth housing 42, so the impeller 44 can be forcibly pushed to rotate. After the impeller 44 rotates, it can drive the generator 41 to generate electricity through the third rod 45. After the generator 41 generates electricity, it can supply power to the drive motor 31. In this way, as long as sewage passes through, the drive motor 31 can be automatically powered without the need for an additional power source (of course, if the generator 41 has a large power, a battery can be added to store the electricity, but there is no specific limitation). In addition, a small portion of the power generated by the generator 41 can be separated and connected to a metal ring electrode between the outer structural layer and the inner insulating and anti-corrosion layer of the second housing 122. This allows a radial high-voltage repulsive electrostatic field to be formed across the inner insulating and anti-corrosion layer between the grounded sewage and the ring electrode with negative high voltage, thereby reducing the probability of negative pressure electrons in the sewage adhering and adsorbing into the second housing 122 and reducing the cleaning frequency.

[0026] Furthermore, in order to enable the dosing mechanism 5 to add chemicals to the wastewater discharged into the power recovery mechanism 4, and to enable the dosing mechanism 5 to change the dosage according to the wastewater flow rate in the power recovery mechanism 4, as a preferred embodiment of the present invention, the dosing mechanism 5 includes a medicine tank 51, a reset component 52, a fourth pipe 53, and a force-bearing component 54. A valve is provided inside the fourth pipe 53. The lower end of the force-bearing component 54 is located inside the third pipe 43, and the upper end of the force-bearing component 54 extends through to the outside of the third pipe 43 and is connected to one end of the reset component 52 and the valve stem of the valve inside the fourth pipe 53. The other end of the reset component 52 is connected to the outer wall of the third pipe 43. The two ends of the fourth pipe 53 are fixedly connected to and communicate with the medicine tank 51 and the third pipe 43, respectively. The medicine tank 51 is fixedly connected to the outer wall of the third pipe 43 through a bracket. More specifically, the force-bearing component 54 includes a first plate 541, a fourth rod 542, and a second plate 543. The lower end of the fourth rod 542 is located inside the third tube 43. One end of the fourth rod 542 inside the third tube 43 is fixedly connected to one side of the second plate 543. The upper end of the fourth rod 542 extends through to the outside of the third tube 43 and is fixedly connected to the inner wall of the first plate 541 and the valve stem of the valve inside the fourth tube 53. The bottom surface of the first plate 541 is connected to the reset component 52. The penetration point of the fourth rod 542 and the third tube 43 is rotatably connected by a sealed bearing. More specifically, the reset assembly 52 includes a third column 521, a plurality of second springs 522 and a plurality of blocks 523. The upper surface of the third column 521 is provided with a plurality of first cavities 524. One end of each of the plurality of second springs 522 is fixedly connected to one end of each of the plurality of first cavities 524. The other end of each of the plurality of second springs 522 is fixedly connected to the lower end of each of the plurality of blocks 523. The upper end of each of the plurality of blocks 523 is fixedly connected to the bottom surface of the first plate 541. The outer wall of each of the plurality of blocks 523 is slidably connected to the inner wall of each of the plurality of first cavities 524. Specifically, such as Figure 3 , Figure 4 , Figure 11 and Figure 12 As shown, during use, when sewage is discharged from the fourth housing 42 into the third pipe 43, this portion of sewage moves from left to right (as shown in the diagram). Figure 3(From the perspective), the second plate 543 will be actuated and rotate to a certain extent with the fourth rod 542 as the axis. As the fourth rod 542 rotates, the valve stems of the first plate 541 and the fourth tube 53 valve, which are connected to the fourth rod 542 outside the third tube 43, will rotate to a certain extent together. As the valve stem of the fourth pipe 53 rotates, the amount of liquid medicine flowing out of the fourth pipe 53 increases. Because several second springs 522 push the block 523, the rotation angle of the fourth rod 542 is limited. As the flow rate of sewage in the third pipe 43 increases and the flow velocity increases, the deflection angle of the second plate 543 can be larger, resulting in more liquid medicine flowing out, thus ensuring that the ratio of liquid medicine to sewage is always more appropriate.

[0027] Working principle: When put into use, the sewage is first pumped tangentially from the second pipe 125 into the third shell 123 by an external pump. The sewage forms a vortex in the funnel-shaped mesh 132, where the solid manure is trapped by the mesh 132, while the liquid passes through the mesh and collects at the bottom of the first shell 121. During the separation process, the drive motor 31 starts and drives the thrust mechanism 6 through the first transmission component 33 and the second transmission component 34. At this time, the central first spiral conveyor 61 and several peripheral second spiral conveyors 62 rotate synchronously. The spiral surface guides the sludge and continuously pushes it downward, forcibly pushing it to the bottom fifth tube 131. When the weight of the sludge accumulated in the fifth tube 131 overcomes the preset elastic force of the first spring 24, the second column 23 moves down and the solid sludge is automatically discharged from the gap. Then, under the rebound force of the first spring 24, the second column 23 resets and seals again. The initially separated liquid wastewater enters the fourth housing 42 through the first pipe 124. The fluid kinetic energy impacts the impeller 44 to rotate, thereby driving the generator 41 to generate electricity. The generated electricity is fed back to the drive motor 31 through the wiring harness or used to establish an anti-scaling electrostatic field on the wall of the second housing 122. Subsequently, the wastewater flows into the third pipe 43 and washes the second plate 543. The force-bearing component 54 synchronously adjusts the opening angle of the valve in the fourth pipe 53 according to the flow rate to achieve adaptive quantitative dosing of the agent, and finally completes the entire wastewater cleaning and purification process.
