Description

Technical Field

[0001] This invention relates to the field of environmentally friendly water treatment equipment for livestock and poultry farming, specifically a device for the harmless treatment and recycling of wastewater from livestock farms. Background Technology

[0002] Large-scale livestock and poultry farming generates a large amount of wastewater containing manure, suspended solids, and organic matter. If this wastewater is discharged or reused directly without effective purification, it can easily cause environmental pollution and the spread of diseases in the farm. Therefore, wastewater filtration and purification, as well as the removal of impurities, are the core processes for the harmless and recyclable treatment of farm wastewater, and directly determine the quality of wastewater treatment water and the stability of equipment operation.

[0003] A search revealed Chinese Patent Publication No. CN220351932U, which discloses a recyclable livestock wastewater treatment device, comprising a treatment tank and a fermentation tank. This device uses a second motor to drive a suction pipe for height adjustment, allowing the pipe to slide up and down within the treatment tank. The upper layer of clean water is drawn from the treatment tank based on its water level. Simultaneously, a water pumping component draws the upper layer of clean water into a purification tank for treatment. A wastewater discharge component draws the lower layer of sediment into the fermentation tank for fermentation. Finally, a venting pipe releases biogas for utilization, thus achieving wastewater recycling. However, the existing technology described above has the following drawbacks: Firstly, the filtration structure lacks a dedicated impurity interception and collection structure. The filtration component can only simply intercept suspended impurities and particulate matter in the wastewater. The intercepted impurities directly accumulate and adhere to the inner side of the filter surface, without a centralized storage space. Under the continuous action of water flow impact and water fluctuations, the accumulated impurities... The wastewater is easily detached from the filter surface and re-mixed into the purified water, causing secondary pollution. This significantly reduces the precision of wastewater filtration and purification, leading to unstable effluent quality and severely impacting the harmless treatment effect and subsequent recycling safety of aquaculture wastewater. Furthermore, the existing equipment lacks an automated scraping and cleaning structure, requiring manual periodic cleaning of the filter surface and internal components. Due to the high impurity content and rapid buildup of wastewater in aquaculture, staff must frequently disassemble, clean, scrape, and descale the filter structure and equipment cavities. This high frequency and cumbersome process greatly increases the workload and labor intensity of manual maintenance. Frequent manual cleaning also necessitates equipment shutdown, interrupting the wastewater treatment process and hindering continuous and routine operation. This significantly reduces the overall efficiency of wastewater treatment and recycling in aquaculture farms, and the equipment lacks ease of use and practicality. Therefore, this paper proposes a wastewater harmless treatment and recycling device for aquaculture farms to address the aforementioned problems. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a device for the harmless treatment and recycling of wastewater from livestock farms, which has the following beneficial effects:

[0019] 1. This wastewater harmless treatment and recycling device for livestock farms constructs a stable impurity interception and collection structure through a filtration mechanism. After the wastewater enters the treatment tank, it flows through the inclined filter plates, which can efficiently intercept large-volume solid impurities such as livestock and poultry manure and feed residue mixed in the wastewater. The intercepted impurities are cleaned and pushed to the right by the cleaning mechanism and directly collected into the collection frame fixedly connected to the filter plates. There is no need for frequent manual cleaning of the filter surface. This not only avoids solid impurities clogging the filter plates, but also achieves centralized collection of impurities, greatly reducing the difficulty of subsequent solid waste cleaning operations and ensuring the continuous and smooth wastewater filtration process.

[0020] 2. This wastewater harmless treatment and recycling device for livestock farms uses a cleaning mechanism to create an adaptive scraping and cleaning structure. A servo motor drives a threaded rod to move the threaded block laterally, while a telescopic spring continuously applies downward pressure, ensuring that the cleaning roller brush remains in close contact with the top surface of the filter plate. During the lateral movement, stubborn impurities attached to the filter plate's pores are thoroughly brushed away. The brushed-off impurities are directly pushed into the collection frame. The entire process eliminates the need for manual cleaning of the filter surface, completely solving the pain points of traditional wastewater treatment devices such as easy clogging and difficult cleaning of filter plates. This effectively extends the continuous service life of the filter plates and significantly improves the operational efficiency of wastewater treatment. Attached Figure Description

[0032] A fixed handle is fixedly installed on the front side of the box door 9. The two box doors 9 are symmetrically distributed and fit together. An anti-slip pad is provided on the bottom of the base plate 1.

[0033] The base plate 1 serves as the supporting base for the entire wastewater treatment unit. Anti-slip pads are installed at the bottom to stably support and position all components, including the treatment tank 2 and purification tank 3, on the ground, preventing displacement and shaking during operation and ensuring the structural stability of the entire wastewater treatment process. The treatment tank 2, as the core pretreatment chamber, provides installation space for the filtration mechanism 7 and the mixing assembly 6. It receives the incoming raw wastewater from the farm, completes the initial solid-liquid filtration and flocculant mixing reaction, and provides pretreated wastewater for subsequent deep purification processes. The qualified wastewater is treated in the purification tank 3, which serves as a deep harmless treatment chamber for wastewater. It receives the pre-treated wastewater pumped in by the conveying component 5 and completes the deep purification of the wastewater through the internal supporting biochemical, disinfection and sedimentation components, finally producing recyclable and qualified clean water. The collection tank 4 is movably installed on the bottom wall of the treatment tank 2 and has an open design on the top to receive the fine sediment that falls from the gaps in the filter plate 73. It can be removed and emptied directly from the tank door 9 on a regular basis, realizing the centralized collection and cleaning of sediment at the bottom and preventing the sediment from accumulating and hardening at the bottom of the treatment tank 2.

[0034] The door 9 is hinged to the front of the inner wall of the treatment box 2, symmetrically distributed and closely fitted to each other. A fixing handle is set on the front. After opening, the collection box 4 and filter plate 73 can be directly removed from the inside of the treatment box 2, which is convenient for operators to quickly complete the internal solid waste cleaning and component maintenance.

[0036] The size and number of filter holes on filter plate 73 can be set according to requirements. The filter holes are designed in a matrix. The tilt angle of filter plate 73 can be set to eight to fifteen degrees.

[0037] The filtration unit 7, as the core unit for the initial solid-liquid filtration of raw wastewater from the farm, intercepts large solid impurities such as livestock and poultry manure and feed residue mixed in the wastewater through the inclined filter plate 73, achieving rapid solid-liquid separation and preventing large impurities from entering subsequent processes and clogging the pipeline. The right-angle support plate 71 is fixed to the top wall inside the treatment tank 2, providing movable support and positioning for the right side of the collection frame 74, limiting the installation position of the collection frame 74, and allowing the collection frame 74 to accurately receive solid impurities sliding off the filter plate 73. The support plate 72 is fixed to the left side of the inner wall of the treatment tank 2, providing support for the left side of the filter plate 73. The support positioning allows the filter plate 73 to be stably installed at an angle of 8 to 15 degrees, ensuring that impurities can slide to the right along the inclined surface. The filter plate 73 is installed at an angle between the support plate 72 and the collection frame 74, and the surface has a matrix distribution of filter holes. The diameter and number of filter holes can be adjusted as needed to efficiently intercept large solid impurities in the sewage, while allowing the filtered sewage to flow smoothly downwards. The collection frame 74 is fixedly connected to the right side of the filter plate 73 to receive solid impurities, realizing the centralized collection of intercepted impurities. It can be removed together with the filter plate 73 during cleaning, greatly improving the convenience of solid waste cleaning.

[0038] The cleaning mechanism 8 includes a top box 801. The top box 801 is fixedly installed on the top front side of the processing box 2. A servo motor 802 is fixedly installed on the left side of the inner wall of the top box 801. A threaded rod 803, which is rotatably connected to the right side of the inner wall of the top box 801, is fixedly installed at the output shaft of the servo motor 802. A threaded block 804 is threadedly connected to the outer side of the threaded rod 803. An outer frame 805 extending to the inner side of the processing box 2 is fixedly installed on the outer side of the threaded block 804. A fixed cylinder 806 located inside the processing box 2 is fixedly installed on the outer side of the outer frame 805. The bottom of the fixed cylinder 806 is opened. There is a circular groove 807. A sliding plate 808 is slidably installed between the front and rear sides of the inner wall of the outer frame 805. A telescopic spring 809 is fixedly installed on the top of the sliding plate 808 and fixedly connected to the inner side of the circular groove 807. A U-shaped frame 810 located below the outer frame 805 is fixedly installed between the left and right sides of the sliding plate 808. A rotating cylinder 811 extending to the rear side is rotatably connected to the front side of the U-shaped frame 810. A rotating rod 812 extending to the rear side is rotatably connected to the front side of the rotating cylinder 811. A cleaning roller brush 813 that fits against the top of the filter plate 73 is fixedly installed on the outer side of the rotating rod 812.

[0039] The inner bottom wall of the top box 801 and the inner top wall of the processing box 2 are both provided with strip-shaped holes that are adapted to the moving trajectory of the outer frame 805, and the inner side of the fixing cylinder 806 is provided with fixing holes that are adapted to the outer frame 805.

[0040] The cleaning mechanism 8, acting as an automatic unclogging unit for the filter plate 73, uses an adaptive, elastically fitting cleaning roller brush 813 to thoroughly remove stubborn impurities adhering to the filter holes of the filter plate 73. This eliminates the need for manual cleaning by opening the cover, preventing clogging of the filter plate 73 and ensuring a long-term stable filtration flow rate. The top box 801, fixed to the front top of the treatment box 2, provides a sealed installation space for transmission components such as the servo motor 802 and the threaded rod 803, preventing sewage and moisture from entering the transmission components and causing corrosion, thus extending their service life. The servo motor 802 provides precise rotational power for the lateral movement of the cleaning mechanism 8, accurately controlling the forward and reverse rotation and the number of rotations of the threaded rod 803, driving the cleaning roller brush 813 to complete a reciprocating cleaning action on the top surface of the filter plate 73. The threaded rod 803 is rotatably mounted between the two ends of the top box 801, converting the rotational motion of the servo motor 802 into the lateral linear motion of the threaded block 804. This provides stable transmission support for the lateral sweeping of the cleaning roller brush 813. The threaded block 804 is threadedly connected to the outside of the threaded rod 803 and moves laterally synchronously with the rotation of the threaded rod 803, driving the outer frame 805 to complete the lateral displacement synchronously and transmitting the power of the sweeping action. The outer frame 805 extends to the inside of the processing box 2, providing sliding installation space for the slide plate 808, and transmitting the lateral movement power of the threaded block 804 to the sweeping components below, ensuring synchronous and smooth sweeping action. The fixed cylinder 806 is fixed to the outside of the outer frame 805, and a circular groove 807 is opened at the bottom for the extension spring 80. The top of the 9 provides a fixed positioning and a mounting carrier for the elastic pressure structure. The circular groove 807 is opened at the bottom of the fixed cylinder 806 to provide a space for the top of the telescopic spring 809 to accommodate and position it, preventing the telescopic spring 809 from shifting laterally when compressed. The sliding plate 808 is slidably installed between the front and rear sides of the inner wall of the outer frame 805, and its top is fixedly connected to the telescopic spring 809. It can move up and down synchronously with the extension and retraction of the telescopic spring 809, driving the U-shaped frame 810 below to adaptively adjust its height. The two ends of the telescopic spring 809 are fixedly connected to the inner wall of the circular groove 807 and the top of the sliding plate 808, respectively, continuously applying elastic pressure downwards to ensure that the cleaning roller brush 813 always fits tightly against the top surface of the filter plate 73, even if there are slight protrusions on the surface of the filter plate 73. To ensure complete contact and effective unclogging, the U-shaped frame 810 is fixed to the bottom of the slide plate 808, providing a rotating mounting carrier for the rotating drum 811 and the rotating rod 812. It stably transmits the downward pressure of the slide plate 808 to the cleaning roller brush 813. The rotating drum 811 is rotatably connected between the front and rear sides of the U-shaped frame 810, providing rotational support and positioning for the rotating rod 812, allowing it to smoothly drive the cleaning roller brush 813 to rotate adaptively. The rotating rod 812 is rotatably mounted inside the rotating drum 811, providing a rotating mounting carrier for the cleaning roller brush 813, allowing it to rotate adaptively according to the resistance of impurities during cleaning, avoiding hard scraping and damage to the filter plate 73 surface. The outer side of the cleaning roller brush 813 is densely covered with wear-resistant bristles, tightly adhering to the top surface of the filter plate 73.During the lateral movement, stubborn impurities embedded in the filter pores can be thoroughly brushed away, effectively unclogging the filter pores and restoring the filtration flux of filter plate 73.

[0041] The conveying assembly 5 includes a pump body 51. The pump body 51 is fixedly installed on the top of the purification box 3.

[0043] The conveying assembly 5 serves as the power unit for conveying pretreated wastewater to the purification tank 3. It can automatically adjust the insertion depth of the movable tube 55 to stably extract and convey the wastewater that has completed the flocculation reaction at the bottom of the treatment tank 2 into the purification tank 3, avoiding the extraction of large solid impurities above the filter plate 73. The pump body 51 provides suction power for wastewater conveyance, extracting wastewater from the treatment tank 2 through the connecting pipe 52 and the movable tube 55, and then pushing it into the purification tank 3 through the output pipe 54, ensuring a stable and smooth wastewater conveyance process. The connecting pipe 52 serves as the fixed conveying pipeline at the input end of the pump body 51, and its outer side is provided with positioning support by the support base 53, providing a guide track for the up and down sliding of the movable tube 55, ensuring that the movable tube 55 will not shift laterally during the lifting and lowering process. The support base 53 is fixed to the top of the purification tank 3 and fits over the outside of the connecting pipe 52, providing rigid support and positioning for the connecting pipe 52, and preventing the connecting pipe 52 from shaking due to long-term impact from the water flow in the pipeline. The deformation enhances the structural stability of the conveying pipeline. The output pipe 54 is fixed to the output end of the pump body 51 and extends to the inside of the purification tank 3, accurately guiding the sewage pumped by the pump body 51 into the purification tank 3, completing the delivery and docking of pre-treated sewage to the deep purification chamber. The movable pipe 55 is slidably installed on the outside of the connecting pipe 52 and can be raised and lowered synchronously with the connecting plate 56. It can be inserted below the sewage surface inside the treatment tank 2 as needed to flexibly adjust the suction position and avoid sucking in surface scum or bottom sediment. The connecting plate 56 is fixed to the outside of the movable pipe 55 and is fixedly connected to the output end of the electric push rod 57, synchronously transmitting the extension and retraction power of the electric push rod 57 to the movable pipe 55, driving the movable pipe 55 to complete a stable raising and lowering action. The electric push rod 57 is fixed on the left side of the purification tank 3, and its output end drives the connecting plate 56 to move up and down, providing power for the raising and lowering adjustment of the movable pipe 55. The depth position of sewage suction can be automatically adjusted without manual operation.

[0044] The mixing assembly 6 includes a mixing drum 61. The mixing drum 61 is fixedly installed on the top of the processing tank 2. A top cover 62 is movably installed on the top of the mixing drum 61. A mixing motor 63 is fixedly installed on the top of the top cover 62. A mixing shaft 64 extending to the inside of the mixing drum 61 is fixedly installed at the output shaft of the mixing motor 63. A mixing blade 65 is fixedly installed on the outside of the mixing shaft 64. A feed pipe 66 extending to the inside of the mixing drum 61 is fixedly installed on the left side of the mixing drum 61. A discharge pipe 67 extending to the inside of the processing tank 2 is fixedly installed on the inner bottom wall of the mixing drum 61.

[0045] The stirring assembly 6 serves as the stirring unit for the wastewater treatment flocculant. It thoroughly mixes the added solid or liquid flocculant into a uniform solution, which is then quantitatively added to the treatment tank 2. This allows the flocculant to fully contact and react with the wastewater, improving the flocculation and sedimentation treatment effect. The stirring drum 61 serves as the mixing chamber for the flocculant, providing installation space for components such as the stirring motor 63 and the stirring shaft 64. It receives the flocculant and clean water added from the feed pipe 66, completing the uniform mixing and preparation of the flocculant. The top cover 62 is movably installed on the top of the stirring drum 61, providing a mounting and positioning carrier for the stirring motor 63, while simultaneously sealing the top opening of the stirring drum 61 to prevent the solution from splashing out during the stirring process. The stirring motor 63 provides rotational power for the mixing of the flocculant and wastewater, driving the stirring shaft 64 and the stirring blades 65 to rotate at high speed, allowing the interior of the stirring drum 61 to rotate smoothly. The agent and water are quickly and evenly mixed. The stirring shaft 64 receives the rotational power of the stirring motor 63, which drives the outer stirring blades 65 to rotate synchronously, and evenly transmits the rotational power to all areas of the stirring drum 61, ensuring that the agent and sewage are mixed without dead corners. The stirring blades 65 rotate synchronously with the stirring shaft 64, which fully agitates the agent and sewage inside the stirring drum 61, quickly breaking up the agglomerates of the agent, allowing the agent to completely dissolve and disperse to form a uniform flocculant solution. The feed pipe 66 is fixed on the left side of the stirring drum 61, serving as the channel for adding flocculant and sewage. Operators can directly add materials into the stirring drum 61 through the feed pipe 66 without frequent opening of the lid. The discharge pipe 67 is fixed on the inner bottom wall of the stirring drum 61 and extends to the inner side of the treatment tank 2, uniformly discharging sewage and flocculant solution into the treatment tank 2.

[0046] When using the equipment, first place the base plate 1 stably near the sewage collection point of the farm, ensuring that the anti-slip pad on the bottom of the base plate 1 is completely in contact with the ground to prevent the machine from shifting during operation. Inject a measured amount of sewage treatment flocculant into the mixing drum 61 through the feed pipe 66, close the top cover 62, and start the mixing motor 63 to drive the mixing shaft 64 and mixing blades 65 to rotate, thoroughly mixing and uniformly mixing the flocculant to complete the pre-mixing of the agent. Then, guide the sewage to be treated from the farm into the treatment tank 2. The sewage flows downward through the inclined filter plate 73, which filters out large-volume solids such as livestock and poultry manure and feed residue mixed in the sewage. Impurities are intercepted and collected inside the collection frame 74. The pre-filtered wastewater falls downwards into the bottom temporary storage area of ​​the treatment tank 2. The control valve of the discharge pipe 67 is opened, and the flocculant prepared inside the mixing drum 61 is uniformly added to the wastewater in the treatment tank 2. After the agent and wastewater are fully mixed, the fine suspended pollutants in the wastewater will quickly flocculate into clumps, completing the flocculation reaction pretreatment of the wastewater. The electric push rod 57 of the conveying component 5 is activated. The electric push rod 57 drives the connecting plate 56 to move downwards, pushing the movable pipe 55 below the wastewater surface at the bottom of the treatment tank 2. The pump body 51 is activated, and the pump body 51 is activated through the connecting pipe 52 and the movable pipe 55. The pretreated wastewater is extracted and transported to the purification tank 3 through the output pipe 54. Inside the purification tank 3, it undergoes deep biochemical degradation, sedimentation, and disinfection for deep harmless treatment. When impurities on the surface of the filter plate 73 increase and the filter holes become clogged, causing the filtration flow rate to slow down, the servo motor 802 of the cleaning mechanism 8 is activated. The servo motor 802 drives the threaded rod 803 to rotate, driving the threaded block 804 to move laterally along the outer frame 805. The telescopic spring 809 applies downward pressure to ensure that the cleaning roller brush 813 remains tightly attached to the top surface of the filter plate 73. During the lateral movement, the cleaning roller brush 813 thoroughly removes stubborn impurities from the gaps in the filter holes of the filter plate 73. The brushed-off impurities are directly pushed into the collection box 74. No manual cleaning is required throughout the process. The clean water that has undergone harmless treatment inside the purification box 3 can be directly discharged through the discharge pipe 10 for irrigation of farmland around the farm and washing of the pen floor, realizing the recycling of water resources. Periodically open the two boxes 9 on the front side of the treatment box 2, remove the collection box 4 from the bottom wall of the treatment box 2, pour out the small amount of sediment accumulated in the box, and at the same time remove the filter plate 73 from the support plate 72 to empty the solid impurities accumulated in the collection box 74. After cleaning, reset all components and restart the device to continue the sewage treatment operation.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0048] In summary, this wastewater harmless treatment and recycling device for livestock farms uses the base plate 1 as the supporting base for the entire machine, integrating the treatment tank 2 and the purification tank 3 into an integrated treatment unit. Through the full-process design of pre-solid-liquid separation, chemical mixing reaction, and deep purification, coupled with the automatically unclogging filter mechanism 7 and the self-adaptive scraping cleaning mechanism 8, it achieves harmless treatment of livestock farm wastewater to meet standards. The treated clean water can be directly used for irrigation and pens cleaning in the livestock farm. This not only solves the pain point of direct discharge of wastewater from traditional livestock farms polluting the surrounding water and soil, but also completes the recycling of water resources, thus achieving both good environmental and economic benefits.
