Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a device for fermenting and treating animal manure. Background Technology

[0002] Livestock manure fermentation technology is an environmentally friendly treatment method that uses microorganisms to transform organic waste into stable fertilizer. In the pretreatment stage, the moisture content of the manure needs to be adjusted, such as controlling the water content to 50%–60% (it should clump together when squeezed but not dripping water).

[0003] In related technologies, to facilitate solid-liquid separation of manure and reduce the drying cycle, for example, patent CN214360943U provides a livestock manure treatment device. This device can break up livestock manure by rotating turbine blades, and the broken manure falls into the fermentation tank, reducing the occurrence of manure accumulating into clumps. This facilitates solid-liquid separation of livestock manure. Furthermore, the piston rod can drive the piston to reciprocate inside the conveying pipe, thereby separating the solid and liquid of the livestock manure inside the fermentation tank. The liquid is pressurized and sent into the pipeline, and then transported to the storage tank. This can quickly complete the solid-liquid separation of livestock manure, further improving the efficiency of livestock manure treatment.

[0004] Although the existing technical solutions mentioned above can achieve the effect of sucking and separating the liquid inside the fermentation tank by setting a piston for reciprocating motion, only sucking to separate the liquid of the feces leaves the water content in the feces still relatively high, making it difficult to further dry the solid feces. This results in a long period of fecal moisture adjustment and reduces the processing efficiency of the feces before fermentation. Summary of the Invention

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0057] The present invention will be further described below with reference to embodiments.

[0058] Please see Figures 1-9 This invention provides a technical solution: a livestock manure fermentation treatment device, comprising a storage tank 1, a filtrate tank 2, a squeezing component 3, and a moving component 4. The filtrate tank 2 is positioned above the storage tank 1; the squeezing component 3 is located inside the filtrate tank 2 and is used to squeeze the manure for dehydration; the moving component 4 is positioned outside the filtrate tank 2 and is used to drive the squeezing component 3 to move along the length of the filtrate tank 2; wherein, a treatment box 11 is fixedly installed on the top of the storage tank 1, and a manure addition pipe 12 is fixedly installed on one end of the treatment box 11 corresponding to the filtrate tank 2; an air inlet pipe 13 and an air outlet pipe 14 are fixedly installed on both sides of the treatment box 11, respectively, for blowing hot air along the length of the filtrate tank 2.

[0059] After the solid-liquid mixture of feces is fed into the filtrate tank 2 through the manure filling pipe 12, the liquid is filtered through the filter cloth laid on the inside of the filtrate tank 2. The filtered liquid flows into the storage tank 1 through the through holes on the side wall and bottom of the filtrate tank 2 for collection. After most of the liquid is filtered, the squeezing component 3 is driven by the moving component 4 to move along the length direction inside the filtrate tank 2. During the movement, the liquid inside the filtrate tank 2 is squeezed separately. The squeezing method separates the liquid that cannot be filtered by itself. The squeezed liquid continues to enter the storage tank 1 through the through holes of the filtrate tank 2. After being connected to a fan through the air inlet pipe 13, hot air can be introduced into the processing box 11 to further dry the feces, thereby reducing the feces moisture adjustment cycle and improving the feces processing efficiency during fermentation.

[0060] The squeezing assembly 3 includes a mounting plate 31 connected to the moving assembly 4. The mounting plate 31 has symmetrically fixed mounting plates 32 at its bottom. A roller 311 is rotatably arranged between the two fixed plates 32. The roller 311 is driven by an external force to rotate and squeeze the feces to separate the liquid.

[0061] During the process of squeezing feces to separate liquid, the moving component 4 drives the mounting plate 31 to move, causing the roller 311 below the mounting plate 31 to rotate under external force, which has a crushing effect on the feces. While separating the liquid, it can help disperse the lumpy feces, which is convenient for subsequent drying work.

[0062] The extrusion assembly 3 also includes a rotating rod 316 arranged in a ring array on the outside of the roller 311. The outside of the roller 311 is provided with a storage groove 319 for storing the rotating rod 316. When the roller 311 is driven to reverse by an external force, the rotating rod 316 is triggered to unfold, which is used to turn the extruded feces.

[0063] In order to effectively improve drying efficiency, when the drum 311 is driven to reverse by external force, the turning rod 316 located outside the drum 311 and housed inside the storage groove 319 will automatically unfold, so as to turn the feces as the drum 311 reverses, preventing the feces from being compacted during liquid separation and affecting drying efficiency.

[0064] Two fixed plates 32 are each fixedly mounted with a fixed shaft 33 on one side close to each other. The extrusion assembly 3 also includes a second disc 310 and a first disc 312 rotatably mounted outside the fixed shaft 33. The second discs 310 are symmetrically arranged outside the two fixed shafts 33. The end faces of the second discs 310 are provided with guide holes 313 in an annular array. The first disc 312 is provided with a sliding groove 321 in an annular array on the side close to the second disc 310. A sliding rod 314 is slidably arranged between the second disc 310 and the first disc 312. The two ends of the sliding rod 314 are respectively slidably arranged inside the guide hole 313 and the sliding groove 321. A push rod 315 is fixedly mounted on the outer side of the sliding rod 314 parallel to the sliding groove 321. A flipping rod 316 is fixedly mounted on the other end of the push rod 315. The inner side of the roller 311 is provided with a sliding hole 318 corresponding to the push rod 315. The two symmetrically arranged second discs 310 are driven to rotate synchronously by external force. The first disc 312 is fixedly mounted on the inner side of the roller 311.

[0065] When the two symmetrically arranged second discs 310 rotate in opposite directions, the second discs 310 drive the slide rod 314 to slide along the slide groove 321 through the guide hole 313 on the end face. This causes the slide rod 314 to push the outer push rod 315 to slide along the slide hole 318, and the push rod 315 to push the flipping rod 316 to move to the outside of the storage groove 319. After the two ends of the slide rod 314 move from one end of the guide hole 313 and the slide groove 321 to the other end, the second discs 310 continue to rotate, which can drive the first disc 312 to rotate together. This, in turn, drives the outer roller 311 to rotate through the first disc 312, thus achieving the effect of turning over the feces during the movement driven by the moving component 4.

[0066] Specifically, flanges 34 are fixedly installed at the ends of the fixed shafts 33 that are close to each other. A first power component 35, which is a drive motor, is fixedly installed between the flanges 34. A first gear 36 is fixedly installed at both output ends of the first power component 35. A second gear 39 is meshed on the outer side of the first gear 36. The fixed shafts 33 and the flanges 34 are connected by connecting blocks 37 arranged in a ring array. A short shaft 38 for installing the second gear 39 is fixedly installed on the side of the flange 34 that is close to the connecting block 37. The second gear 39 is meshed on the inner side of the corresponding second disc 310. The second disc 310 is a disc-shaped body with an internal gear ring.

[0067] When the drive roller 311 rotates, the first power component 35 fixed between the two fixed shafts 33 drives the two first gears 36 to rotate. The first gears 36 drive the second gear 39 outside the short shaft 38 to rotate through the gap between the connecting blocks 37. The second gears 39 synchronously drive the two symmetrically arranged second discs 310 to rotate. By driving the second discs 310 to rotate in both directions, the work of squeezing, dehydrating and turning the feces is realized.

[0068] The push rod 315 is fixedly connected to the flipping rod 316 through the tapered connecting sleeve 317. The tapered connecting sleeve 317 is slidably disposed inside the sliding hole 318, and the shape of the sliding hole 318 matches that of the tapered connecting sleeve 317.

[0069] To prevent fecal liquid from entering the interior of the drum 311 during the squeezing and separation process, when the second disc 310 drives the slide rod 314 to pull the flipping rod 316 into the receiving groove 319 for storage, the slide rod 314 drives the push rod 315 to slide into the sliding hole 318. The sliding hole 318 and the tapered connecting sleeve 317 at the end of the push rod 315 cooperate with each other to seal the sliding hole 318 and prevent fecal liquid from entering the interior of the drum 311 through the sliding hole 318.

[0070] The livestock manure fermentation treatment device disclosed in this application embodiment also includes a support frame 5. A trough door 22 is fixedly installed on the outside of the support frame 5. The trough door 22 is movably installed at the discharge end of the filtrate tank 2. The other end of the support frame 5 is rotatably installed inside the filtrate tank 1. The support frame 5 is driven by external force to open and close the trough door 22.

[0071] To facilitate the discharge of dried and conditioned feces from the filtrate tank 2, a detachable gate 22 is installed at the discharge end of the filtrate tank 2. During discharge, the gate 22 is automatically opened by the support frame 5, thus achieving automated discharge.

[0072] The movable component 4 includes a movable seat 41, which is driven by an external force to slide along the channel steel 24. The channel steel 24 is fixedly installed on both sides of the filtrate tank 2 by a baffle 23. A flow gap is left between the baffle 23 and the filtrate tank 2. The movable seat 41 is installed at the bottom of the mounting plate 31.

[0073] Specifically, a surrounding plate 21 is fixedly installed at the bottom of the filtrate tank 2, and the surrounding plate 21 is fixedly connected to the baffle 23. A fixed sleeve 46 is fixedly installed at the top of the movable seat 41, and a sliding column 47 is slidably installed inside the fixed sleeve 46. A support plate 48 is fixedly installed at the top of the sliding column 47, and the support plate 48 is fixedly installed to the mounting plate 31. A lifting assembly 49 for driving the support plate 48 to rise and fall is fixedly installed at the top of the movable seat 41, which is used to drive the roller 311 to adjust the height, thereby adjusting the squeezing depth of the feces. A toothed plate 25 is fixedly installed at the top of the channel steel 24, and a third gear 44 is rotatably installed on one side of the movable seat 41. The third gear 44 is meshed on the top of the toothed plate 25. A second power component 45 for driving the third gear 44 to rotate is fixedly installed on the outside of the movable seat 41. The second power component 45 is a drive motor. This drives the movable seat 41 to slide along the outside of the channel steel 24, so that the movable seat 41 drives the squeezing assembly 3 to move inside the filtrate tank 2.

[0074] A side plate 15 is fixedly installed on the top of the liquid storage tank 1, and a support 16 is fixedly installed on the top of the side plate 15. The support 16 is located in the middle of both sides of the filter tank 2 and is used to rotatably install the filter tank 2. A top plate for supporting the support 16 is fixedly installed on the side of the side plate 15 away from the discharge end of the filter tank 2. The length of the channel steel 24 is greater than the length of the filter tank 2, and the excess length is located at the discharge end of the filter tank 2. A strip-shaped hole 26 is opened on the inner side of the channel steel 24 for the excess length. The strip-shaped hole 26 is close to the discharge end of the filter tank 2. A limiting groove 27 is provided at the top of one end of the movable seat 41; a connecting shaft 51 is fixedly provided inside the support frame 5, and a sliding sleeve 52 is rotatably provided at both ends of the connecting shaft 51. The sliding sleeve 52 is slidably installed inside the strip hole 26 and is in a vertical state when it is engaged inside the limiting groove 27; an annular plate 42 is fixedly provided outside the movable seat 41, and a stop block 43 is fixedly provided inside the annular plate 42, which is used to push the sliding sleeve 52 out of the limiting groove 27 when the movable seat 41 moves to the discharge end of the filtrate tank 2.

[0075] During material feeding, the second power component 45 drives the movable seat 41 to move along the channel steel 24 towards the feeding end of the filtrate tank 2. Simultaneously, it drives the stop block 43 on the inner side of the annular plate 42 to move closer to the sliding sleeve 52 until the stop block 43 pushes the sliding sleeve 52 out of the limiting groove 27 and into the inner side of the strip hole 26. At this time, the support frame 5 changes from a vertical state to an inclined state. Furthermore, because the movable seat 41 drives the extrusion assembly 3 to the feeding end of the filtrate tank 2, the feeding end of the filtrate tank 2 loses its support and balance, causing the feeding end of the filtrate tank 2 to automatically rotate downwards around the support 16. The frame 5 moves the gate 22 away from the discharge end of the filtrate tank 2, so that the feces inside the filtrate tank 2 can be automatically tilted downwards for discharge. After the discharge is completed, the moving seat 41 drives the squeezing assembly 3 to move away from the discharge end of the filtrate tank 2. During the movement, the annular plate 42 drives the sliding sleeve 52 to move closer to the limiting groove 27. When the moving seat 41 moves to the end, the annular plate 42 drives the sliding sleeve 52 to be located inside the limiting groove 27 to support the filtrate tank 2 again, so as to maintain the stability of the filtrate tank 2, and automatically install the gate 22 at the discharge end of the filtrate tank 2, making it more convenient to use.

[0076] An inclined plate 17 is fixedly installed on each side of the side plates 15 that are close to each other. An elastic buffer assembly is provided on the top of the inclined plate 17 to buffer and prevent the filtrate tank 2 from impact when it is tilted. A counterweight 320 is fixedly installed on the inner side of the roller 311. When it is driven to rotate by an external force, it vibrates and is used to discharge the dried feces inside the filtrate tank 2. In order to prevent the filtrate tank 2 from impacting the side plates 15 or the support frame 5 when it tilts downward, an elastic buffer assembly is provided on the top of the inclined plate 17 on the outer side of the side plates 15 to buffer the impact generated when the filtrate tank 2 rotates downward.

[0077] Specifically, the elastic buffer assembly includes a limiting rod 18 slidably disposed inside the inclined plate 17, an anti-collision block 19 fixedly disposed on the top of the limiting rod 18, and a spring 110 disposed on the outside of the limiting rod 18 between the anti-collision block 19 and the inclined plate 17; furthermore, in order to make it easier to discharge material after the filtrate tank 2 is tilted, the roller 311 is driven to rotate during material discharge, so that the roller 311 drives the counterweight block 320 installed on the inner wall to rotate, thereby applying a vibration force to the filtrate tank 2 through the roller 311. Combined with the elastic buffer assembly at the bottom of the filtrate tank 2, it is in a vibrating state during material discharge, which is more conducive to the discharge of feces inside the filtrate tank 2.

[0078] The principle and advantages of livestock manure fermentation treatment devices:

[0079] First, the solid-liquid mixture of feces is fed into the filtrate tank 2 through the manure feeding pipe 12. The liquid is then filtered through the filter cloth laid on the inside of the filtrate tank 2. The filtered liquid flows into the storage tank 1 through the through holes on the side wall and bottom of the filtrate tank 2 for collection.

[0080] After most of the liquid is filtered, the third gear 44 is driven to rotate by the second power component 45, which in turn drives the movable seat 41 to slide along the channel steel 24. This causes the movable seat 41 to move the mounting plate 31 mounted on the top. During the movement of the mounting plate 31, the first power component 35, which is fixed between the two fixed shafts 33, drives the two first gears 36 to rotate. The first gears 36 drive the second gear 39 on the outside of the short shaft 38 to rotate through the gap between the connecting blocks 37. The second gears 39 synchronously drive the two symmetrically arranged second discs 310 to rotate in the forward direction. The height of the mounting plate 31 is adjusted by the lifting component 49 fixed on the top of the movable seat 41. The pressure can be adjusted during repeated squeezing to achieve different degrees of squeezing.

[0081] After the liquid is squeezed and separated, the second disc 310 is reversed by the first power component 35, causing the second disc 310 to drive the slide rod 314 to slide along the slide groove 321 through the guide hole 313 on the end face. This causes the slide rod 314 to push the outer push rod 315 to slide along the slide hole 318, and the push rod 315 to push the flipping rod 316 to move to the outside of the receiving groove 319 (i.e., the first working state). When the two ends of the slide rod 314 move from one end of the guide hole 313 and the slide groove 321 to the other end, the second disc 310 continues to rotate, which can drive the first disc 312 to rotate together (i.e., the second working state). This causes the outer roller 311 to rotate through the first disc 312, thus achieving the effect of turning over the feces during the movement driven by the moving component 4.

[0082] To prevent fecal liquid from entering the interior of the drum 311 during the squeezing and separation process, when the second disc 310 drives the slide rod 314 to pull the turning rod 316 into the receiving trough 319 for storage, the slide rod 314 drives the push rod 315 to slide into the sliding hole 318. The sliding hole 318 and the tapered connecting sleeve 317 at the end of the push rod 315 cooperate with each other to seal the sliding hole 318, preventing fecal liquid from entering the interior of the drum 311 through the sliding hole 318. At this time, after connecting the blower through the air inlet pipe 13, hot air can be input into the interior of the processing box 11 to further dry the feces, thereby reducing the feces moisture adjustment cycle and improving the feces processing efficiency during fermentation.

[0083] It is worth noting that the above-mentioned fecal-liquid separation method has the following advantages:

[0084] Firstly, after natural filtration through the filter cloth inside the filtrate tank 2, the liquid inside the filtrate tank 2 can be separated by squeezing component 3. The squeezing component 3 is driven by moving component 4 to move and squeeze, so as to ensure the initial separation effect of the fecal liquid and to crush the feces. While separating the liquid, it can help disperse the lumpy feces, which is convenient for subsequent drying work.

[0085] Secondly, by connecting a fan to the air inlet pipe 13, hot air can be introduced into the processing box 11, which can further dry the feces, thereby reducing the feces moisture adjustment cycle and improving the feces processing efficiency during fermentation.

[0086] Thirdly, by driving the roller 311 to rotate in the reverse direction, the flipping rod 316 stored on the outside of the roller 311 can be unfolded. Under the rotation of the roller 311, the flipping rod 316 flips the extruded and dehydrated manure, allowing the manure to quickly and fully contact the hot air inside the processing box 11, and facilitating subsequent material feeding.

[0087] Fourthly, the second disc 310, which is symmetrically arranged inside the drum 311, drives the flipping rod 316 to perform the storage and unfolding actions. The second disc 310 rotates under the drive of the first power component 35. The overall structure is compact, which reduces the space occupied by the drum 311. The outer side of the drum 311 is set close to the inner wall of the filtrate tank 2 to ensure the efficiency of squeezing and dewatering.

[0088] Fifthly, to prevent fecal liquid from entering the interior of the drum 311 during the squeezing and separating process, when the second disc 310 drives the slide rod 314 to pull the flipping rod 316 into the receiving groove 319 for storage, the slide rod 314 drives the push rod 315 to slide into the sliding hole 318. Through the cooperation between the sliding hole 318 and the tapered connecting sleeve 317 at the end of the push rod 315, the sliding hole 318 can be sealed to prevent fecal liquid from entering the interior of the drum 311 through the sliding hole 318.

[0089] In the livestock manure fermentation treatment device of this application, when the filtrate tank 2 is being fed, the second power component 45 drives the moving seat 41 to move along the channel steel 24 towards the feeding end of the filtrate tank 2. At the same time, it drives the stop block 43 on the inner side of the annular plate 42 to move closer to the sliding sleeve 52 until the stop block 43 pushes the sliding sleeve 52 away from the limiting groove 27 and into the inner side of the strip hole 26. At this time, the support frame 5 changes from a vertical state to an inclined state. And because the moving seat 41 drives the squeezing component 3 to be located at the feeding end of the filtrate tank 2, the feeding end of the filtrate tank 2 loses its support and also loses its balance. As a result, the feeding end of the filtrate tank 2 automatically rotates downward around the support 16. At the same time, the support frame 5 drives the tank door 22 away from the feeding end of the filtrate tank 2 so that the manure inside the filtrate tank 2 can automatically tilt downward and be fed.

[0090] When discharging, the drive roller 311 rotates, causing the roller 311 to drive the counterweight 320 installed on the inner wall to rotate, thereby applying vibration force to the filtrate tank 2 through the roller 311. In conjunction with the elastic buffer component at the bottom of the filtrate tank 2, it is in a vibrating state when discharging, which is more conducive to the discharge of feces inside the filtrate tank 2.

[0091] After the material is fed, the moving seat 41 drives the extrusion assembly 3 to move away from the material feeding end of the filtrate tank 2. During the movement, the annular plate 42 drives the sliding sleeve 52 to move closer to the limiting groove 27. When the moving seat 41 moves to the end, the annular plate 42 drives the sliding sleeve 52 to be located inside the limiting groove 27 to support the filtrate tank 2 again, so as to maintain the stability of the filtrate tank 2. The tank door 22 is automatically installed at the material feeding end of the filtrate tank 2, making it more convenient to use.

[0092] It is worth noting that the above-mentioned material feeding method has the following advantages:

[0093] Advantage 1: By driving the support frame 5 through the movable seat 41 to change the support state of the filtrate tank 2, the filtrate tank 2 becomes unbalanced and automatically rotates and tilts to the side where it is discharging. At the same time, the support frame 5 drives the tank door 22 away from the discharge end of the filtrate tank 2, so that the feces inside can be discharged.

[0094] Secondly, during the tilting and rotation of the filtrate tank 2, the elastic buffer assembly at the top of the inclined plate 17 buffers the impact generated when the filtrate tank 2 rotates downward, and the roller 311 applies vibration force to the filtrate tank 2, so that the filtrate tank 2 is tilted and vibrating when discharging, which is more conducive to the discharge of feces inside the filtrate tank 2.

[0095] Thirdly, by opening a limiting groove 27 on the inner side of the channel steel 24 to limit the support frame 5, the support frame 5 is in a vertical state to support the discharge end of the filtrate tank 2. During discharge, the moving seat 41 drives the stop block 43 to push the sliding sleeve 52 away from the limiting groove 27, triggering the discharge action. After discharge, the moving seat 41 drives the annular plate 42 to move synchronously, which can pull the sliding sleeve 52 back to the inner side of the limiting groove 27 for limiting, so as to facilitate the reuse of the treatment device.
