Description

Technical Field

[0001] This invention relates to the field of manure treatment, and more specifically, to an apparatus for the deep alkalization treatment of agricultural manure solid waste. Background Technology

[0002] Most livestock farms are large-scale, with livestock kept in pens where they eat and drink. Livestock excrement is directly discharged into the pens and then drained through slatted floors. The manure mainly contains large amounts of animal excrement and urine, and after treatment, it can be used as organic fertilizer.

[0003] However, existing equipment occupies a large area, and the wastewater requires feeding devices between different units, resulting in a long feeding time. The wastewater fermentation process is lengthy, requiring stirring several times throughout the process. The fermentation process must be carried out in a closed environment, necessitating excellent sealing of the fermentation equipment.

[0004] To address the aforementioned technical issues, Chinese Patent CN213623807U discloses a livestock manure treatment device. Manure is added to the fermentation tank through a first inlet, while mixed materials are added through a second inlet. After fermentation, the manure is pumped into a crushing drum for further crushing. After crushing, the manure is dried in a drying drum before being discharged. The overall structure is stacked vertically, saving space and shortening the manure feeding time, thus reducing the processing cycle. However, after crushing the manure, the lack of timely removal of internal moisture results in a high water content in the solid waste, diluting the alkaline reagent concentration. This necessitates a significant increase in reagent dosage to achieve the target pH value, significantly increasing treatment costs. Furthermore, the undehydrated product after alkalization fails to meet the requirements for organic fertilizer utilization. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a device for the deep alkalization treatment of agricultural manure solid waste.

[0010] Furthermore, the centrifugal assembly includes a support groove symmetrically opened inside the circular frame and a triangular block fixed in the middle of the inner surface of the alkalization treatment tank. A support slider is slidably connected inside the support groove. A centrifugal filter screen is fixedly connected to one side of the two support sliders that are close to each other. A drive rod is fixedly connected to the bottom of the outer surface of the centrifugal filter screen.

[0011] Furthermore, the centrifugal filter screen slides inside the circular frame, the drive rod slides relative to the hypotenuse of the triangular block, the bottom of the centrifugal filter screen is funnel-shaped, and a valve is provided at the bottom of the centrifugal filter screen.

[0012] Furthermore, a drain assembly is provided at the middle of the inner surface of the alkalization treatment tank. The drain assembly includes an annular groove fixed at the middle of the inner surface of the alkalization treatment tank and an L-shaped rod symmetrically fixed at the bottom of the outer surface of the alkalization treatment tank. A scraper is fixedly connected to the bottom of the L-shaped rod, and a drain pipe is fixedly connected to one side of the bottom of the L-shaped rod.

[0013] Furthermore, the L-shaped rod and the scraper are located inside the annular groove, the L-shaped rod is located below the drive rod, and the other end of the drain pipe is connected to the sewage tank.

[0014] Furthermore, a spray assembly is provided at the middle of the outer surface of the alkalization treatment tank. The spray assembly includes a water storage tank and a water pump fixed to the outer surface of the alkalization treatment tank, and a mixing assembly provided at the bottom of the alkalization treatment tank. A first conduit is fixedly connected to the bottom of the water storage tank, and a second conduit is fixedly connected to the output end of the water pump. An annular pipe is fixedly connected to one side of the second conduit. Water spray nozzles are evenly opened on the outer surface of the annular pipe. A circular ring is slidably fitted on the outer surface of the annular pipe. Grooves are evenly opened on the outer surface of the circular ring. A telescopic rod is fixedly connected to the top of the circular ring on an axisymmetrical basis.

[0015] Furthermore, the top of the telescopic rod is fixedly connected to the bottom of the centrifugal filter, one end of the first conduit is fixedly connected to one end of the water pump, and the water pump is located below the water storage tank.

[0016] Furthermore, the mixing assembly includes a second drive motor fixed to the bottom of the alkalization tank and a second annular rack fixed to the bottom of the inner surface of the alkalization tank. The output end of the second drive motor is fixedly connected to a stirring shaft. A stirring frame is fixedly connected to the outer surface of the third gear. A vertical rod is rotatably connected inside the stirring frame. A third gear is fixedly connected to the top of the vertical rod.

[0017] Furthermore, the top of the vertical rod extends into the interior of the stirring frame, the stirring shaft meshes with the second annular rack, and the transverse stirring blade is located inside the stirring frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution incorporates a pretreatment component and a centrifugal component, which can crush the solid waste into small particles, improving material homogeneity and reducing the risk of subsequent blockage. The crushed solid waste then enters the centrifugal component for dehydration, removing moisture from the solid waste. This prevents excessive moisture from diluting the alkaline reagent during subsequent alkalization, effectively increasing the reaction rate between the reagent and the solid waste. The integrated crushing and dehydration mode reduces the use of multiple devices, making the device more functional and reducing energy consumption.

[0020] 2. This solution incorporates a triangular block and a drive rod. During the circular motion of the drive rod, it first contacts and slides against the hypotenuse of the triangular block, raising the height of the centrifugal filter screen. After passing the triangular block, the centrifugal filter screen falls back to its original position under gravity. This continuous up-and-down shaking of the centrifugal filter screen within the circular frame dislodges solid waste adhering to its inner surface, preventing clogging of the filter pores, increasing the dehydration rate, and effectively ensuring that the pretreatment time is controlled within a reasonable range, thus avoiding excessive time that could reduce the efficiency of the alkalization treatment device.

[0021] 3. This solution incorporates a wastewater discharge component. The scraper can push wastewater away from the discharge pipe, moving it to the discharge pipe for outflow. Even when the centrifugal filter screen rotates, it may be lifted slightly by the triangular block and drive rod, but most of the time the scraper slides inside the annular groove and does not affect the water flow. This prevents wastewater from remaining inside the annular groove, thus avoiding wastewater fermentation and gas generation that could impact the surrounding environment. Attached Figure Description

[0039] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 8 A device for deep alkalization treatment of agricultural manure solid waste includes a support leg 3, an alkalization treatment tank 1 is provided on the top of the support leg 3, a top plate 4 is fixedly connected to the top of the alkalization treatment tank 1, a feed inlet 2 is provided inside the top plate 4, and a pretreatment component 5 for crushing solid waste is provided on the inner surface of the alkalization treatment tank 1.

[0041] like Figure 2-3 As shown, the pretreatment component 5 includes two first drive motors 51 fixed to the outer surface of the alkalization tank 1, a first annular rack 53 slidably connected to the top of the inner surface of the alkalization tank 1, and two rotating shafts 54 rotating on the top of the inner surface of the alkalization tank 1. The output end of the first drive motor 51 is fixedly connected to a first gear 52. A crushing roller 55 is fixedly connected to the middle of the outer surface of the rotating shaft 54. A second gear 59 is fixedly connected to one side of the outer surface of the rotating shaft 54. A circular frame 58 is fixedly connected to the bottom of the first annular rack 53. A centrifugal component 56 is arranged inside the circular frame 58.

[0042] The output end of the first drive motor 51 extends into the interior of the alkalization treatment tank 1. The first gear 52 meshes with the first ring rack 53, and the second gear 59 meshes with the first ring rack 53. The two second gears 59 are arranged in a centrally symmetrical manner.

[0043] Feces and solid waste are poured into the alkalization treatment tank 1 through the feed inlet 2. Simultaneously, two first drive motors 51 are turned on. The first drive motors 51 drive the first gear 52 to rotate. The two first gears 52 drive the circular frame 58 to rotate in a circular motion through the first ring rack 53. When the first ring rack 53 rotates, it drives the rotating shaft 54 ​​to rotate through the two second gears 59. The two rotating shafts 54 crush the feces and solid waste into small particles, improving the homogeneity of the material and reducing the risk of subsequent blockage. The crushed solid waste enters the centrifugal component 56 for dehydration treatment, which removes the water from the solid waste. This avoids excessive water from diluting the alkaline reagent during subsequent alkalization, effectively improving the reaction rate between the reagent and the solid waste. By using the integrated crushing and dehydration mode, the use of multiple devices can be reduced, making the device more functional and reducing energy consumption.

[0044] like Figure 3-4 As shown, the centrifugal assembly 56 includes a support groove 562 symmetrically opened inside the circular frame 58 and a triangular block 564 fixed in the middle of the inner surface of the alkali treatment tank 1. A support slider 563 is slidably connected inside the support groove 562. A centrifugal filter screen 561 is fixedly connected to one side of the two support sliders 563 that are close to each other. A drive rod 565 is fixedly connected to the bottom of the outer surface of the centrifugal filter screen 561.

[0045] The centrifugal filter screen 561 slides inside the circular frame 58. The drive rod 565 slides against the hypotenuse of the triangular block 564. The bottom of the centrifugal filter screen 561 is funnel-shaped and a valve is provided at the bottom of the centrifugal filter screen 561.

[0046] When manure and solid waste are crushed and dehydrated, the uniformity of the material can be improved, and the moisture content of the material can be effectively reduced. During centrifugation, due to the huge centrifugal force, the solid waste adheres to the surface of the centrifugal filter screen 561, causing blockage of the filter pores inside the centrifugal filter screen 561 and greatly reducing the dehydration rate. Therefore, when the centrifugal filter screen 561 rotates at high speed inside the alkali treatment tank 1, it synchronously drives the drive rod 565 to rotate. When the drive rod 565 moves to the triangular block 564, the drive rod 565 first contacts the hypotenuse of the triangular block 564 and slides against it, so that the height of the centrifugal filter screen 561 is raised, and the two support sliders 563 slide synchronously inside the support groove 562. When the drive rod 565 passes the triangular block 564, the centrifugal filter screen 561 falls and resets under the action of gravity. As a result, the centrifugal filter screen 561 continuously shakes up and down inside the circular frame 58, which can shake off the solid waste attached to the inner surface of the centrifugal filter screen 561, avoid clogging of the filter holes of the centrifugal filter screen 561, improve the dewatering rate, and effectively ensure that the pretreatment time is controlled within a reasonable range, avoiding the low working efficiency of the alkalization treatment device due to excessive time.

[0047] like Figure 3-4 As shown, a drain assembly 57 is provided in the middle of the inner surface of the alkalization treatment tank 1. The drain assembly 57 includes an annular groove 571 fixed in the middle of the inner surface of the alkalization treatment tank 1 and an L-shaped rod 572 fixed symmetrically to the bottom of the outer surface of the alkalization treatment tank 1. A scraper 573 is fixedly connected to the bottom of the L-shaped rod 572, and a drain pipe 574 is fixedly connected to one side of the bottom of the L-shaped rod 572.

[0048] The L-shaped rod 572 and the scraper 573 are located inside the annular groove 571. The L-shaped rod 572 is located below the drive rod 565, and the other end of the drain pipe 574 is connected to the sewage tank.

[0049] When the centrifugal filter 561 dehydrates solid waste, the wastewater also needs to be treated. At this time, the wastewater is thrown onto the inner wall of the alkalization treatment tank 1 and flows into the annular trough 571 for collection. A portion of the wastewater is transferred to the wastewater pool through the drain pipe 574. However, the wastewater far from the drain pipe 574 cannot flow into the drain pipe 574. Therefore, while the centrifugal filter 561 rotates, it drives two scraper blades 573 to rotate inside the annular trough 571. The scraper blades 573 can push the wastewater and move it to the drain pipe 574 for discharge. Even though the centrifugal filter 561 is lifted slightly by the triangular block 564 and the drive rod 565 when it rotates, the scraper blades 573 slide inside the annular trough 571 most of the time and do not affect the flow of water. This can prevent the wastewater from staying inside the annular trough 571 and prevent the wastewater from fermenting and producing gas, which would affect the surrounding environment.

[0050] like Figure 5-7 As shown, a spray assembly 6 is provided in the middle of the outer surface of the alkalization treatment tank 1. The spray assembly 6 includes a water storage tank 61 and a water pump 63 fixed to the outer surface of the alkalization treatment tank 1, and a mixing assembly 66 provided at the bottom of the alkalization treatment tank 1. A first conduit 62 is fixedly connected to the bottom of the water storage tank 61, and a second conduit 65 is fixedly connected to the output end of the water pump 63. An annular pipe 64 is fixedly connected to one side of the second conduit 65. Spray nozzles 69 are evenly opened on the outer surface of the annular pipe 64. A circular ring 67 is slidably fitted on the outer surface of the annular pipe 64. Grooves 610 are evenly opened on the outer surface of the circular ring 67. A telescopic rod 68 is fixedly connected to the top of the circular ring 67 axially symmetrically.

[0051] The top of the telescopic rod 68 is fixedly connected to the bottom of the centrifugal filter screen 561, and one end of the first conduit 62 is fixedly connected to one end of the water pump 63, which is located below the water storage tank 61.

[0052] After the pretreatment of crushing and dewatering of feces and solid waste, the material falls into the alkalization treatment tank 1 through a valve. During the falling process, the water pump 63 is started to transport the alkaline reagent in the water storage tank 61 to the second conduit 65 through the first conduit 62. The reagent then enters the annular pipe 64 through the second conduit 65 and is sprayed out through the spray nozzle 69 on the annular pipe 64. The spray nozzle 69 can spray the solid waste in all directions, which can increase the contact area between the alkaline reagent and the solid waste, avoid a large amount of high-concentration alkaline solution being concentrated in one place, which can easily cause a sudden increase in local pH, causing protein denaturation and clumping in the feces. At the same time, it shortens the alkalization time and improves work efficiency.

[0053] While the alkaline reagent is sprayed from the nozzle 69, the centrifugal filter 561 simultaneously performs dehydration. The telescopic rod 68 drives the ring 67 to rotate on the outer surface of the annular tube 64. The ring 67 drives the slot 610 to rotate. When the slot 610 and the nozzle 69 are misaligned, the nozzle 69 can be sealed to stop spraying the alkaline reagent. When the nozzle 69 and the slot 610 overlap, the nozzle 69 continues to spray the alkaline reagent. This allows for intermittent spraying, increases the contact area between the reagent and solid waste, avoids excessive use of the reagent, and reduces costs.

[0054] like Figure 5 and Figure 8 As shown, the mixing component 66 includes a second drive motor 661 fixed to the bottom of the alkalization tank 1 and a second annular rack 667 fixed to the bottom of the inner surface of the alkalization tank 1. The output end of the second drive motor 661 is fixedly connected to a stirring shaft 664. A stirring frame 663 is fixedly connected to the outer surface of the third gear 662. A vertical rod 665 is rotatably connected inside the stirring frame 663. The top of the vertical rod 665 is fixedly connected to the third gear 662. A transverse stirring blade 666 is fixedly connected to the outer surface of the vertical rod 665.

[0055] The top of the vertical rod 665 extends out of the interior of the stirring frame 663, the stirring shaft 664 meshes with the second annular rack 667, and the transverse stirring blade 666 is located inside the stirring frame 663.

[0056] When solid waste enters the bottom of the alkali treatment tank 1, the second drive motor 661 is started to drive the stirring shaft 664 to rotate. The stirring shaft 664 drives the two stirring frames 663 to rotate. The stirring frames 663 drive the third gear 662 to rotate in a circular motion. When the third gear 662 moves, it rotates on the inner surface of the second ring rack 667, which in turn drives the transverse stirring blade 666 to rotate through the vertical rod 665. This causes the transverse stirring blade 666 to rotate in a circular motion, which can fully stir the solid waste, mix the alkaline reagent with the waste, and improve the alkali treatment rate.

[0057] Instructions for use: Pour the feces and solid waste into the alkalization treatment tank 1 through the feed inlet 2. Simultaneously turn on the two first drive motors 51. The first drive motors 51 drive the first gears 52 to rotate. The two first gears 52 drive the circular frame 58 to rotate in a circular motion through the first ring rack 53. When the first ring rack 53 rotates, it drives the rotating shaft 54 ​​to rotate through the two second gears 59. The two rotating shafts 54 crush the feces and solid waste.

[0058] The crushed solid waste enters the centrifugal filter 561 for dehydration. When the centrifugal filter 561 rotates at high speed inside the alkalization tank 1, it synchronously drives the drive rod 565 to rotate. When the drive rod 565 moves to the triangular block 564, it first contacts the inclined side of the triangular block 564 and slides against it, which raises the height of the centrifugal filter 561. The two support sliders 563 slide synchronously inside the support groove 562. When the drive rod 565 passes the triangular block 564, the centrifugal filter 561 falls back to its original position under the action of gravity. Thus, the centrifugal filter 561 shakes up and down continuously inside the circular frame 58, which can shake off the solid waste attached to the inner surface of the centrifugal filter 561 and avoid clogging the filter holes of the centrifugal filter 561.

[0059] While the centrifugal filter screen 561 is rotating, it drives the two scraper blades 573 to rotate inside the annular groove 571. The scraper blades 573 can push the sewage and move it to the drain pipe 574 to flow out. Even if the centrifugal filter screen 561 is lifted slightly under the action of the triangular block 564 and the drive rod 565 when it is rotating, the scraper blades 573 slide inside the annular groove 571 most of the time and will not affect the flow of water.

[0060] The water pump 63 is started to transport the alkaline reagent inside the water storage tank 61 through the first conduit 62 to the inside of the second conduit 65, and then into the inside of the annular pipe 64 through the second conduit 65. The reagent is then sprayed out through the spray nozzle 69 on the annular pipe 64. The spray nozzle 69 can spray the solid waste in all directions, which can increase the contact area between the alkaline reagent and the solid waste.

[0061] While the alkaline reagent is being sprayed from the nozzle 69, the centrifugal filter 561 simultaneously performs dehydration. The telescopic rod 68 drives the ring 67 to rotate on the outer surface of the annular tube 64. The ring 67 drives the slot 610 to rotate. When the slot 610 and the nozzle 69 are misaligned, the nozzle 69 can be sealed to stop spraying the alkaline reagent. When the nozzle 69 and the slot 610 overlap, the nozzle 69 continues to spray the alkaline reagent, thus achieving intermittent spraying.

[0062] The second drive motor 661 is started to drive the stirring shaft 664 to rotate. The stirring shaft 664 drives the two stirring frames 663 to rotate. The stirring frames 663 drive the third gear 662 to rotate in a circular motion. When the third gear 662 moves, it rotates on the inner surface of the second ring rack 667, which in turn drives the transverse stirring blade 666 to rotate through the vertical rod 665. This causes the transverse stirring blade 666 to rotate in a circular motion, which can fully stir the solid waste, mix the alkaline reagent with the waste, and improve the alkali treatment rate.

[0063] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
