Description

Technical Field

[0001] The present invention relates to the technical field of biogas slurry production, and particularly to an organic biogas slurry production device and process rich in organic matter. Background Art

[0002] Duck manure is the feces excreted by ducks. It usually contains rich organic substances and nutrients such as nitrogen, phosphorus, and potassium. A large amount of duck manure is produced every day in meat duck farms. How to efficiently treat duck manure is an important issue. The existing treatment methods generally utilize the organic substances in duck manure to generate biogas through an anaerobic fermentation process, and at the same time produce organic liquid fertilizer (i.e., organic biogas slurry). This organic biogas slurry contains rich nutrients and can be used as farmland fertilizer.

[0003] In the process of producing organic biogas slurry from duck manure, generally, steps such as raw material pretreatment (crushing), airtight fermentation, and solid-liquid separation are required. The liquid separated from the solid-liquid separation is the organic biogas slurry.

[0004] In the process of solid-liquid separation, generally, the organic biogas slurry is extracted by means of pressure filtration. The organic biogas slurry is stored in a storage tank after passing through the filter plate. Under long-term operation, solid particles may block the filter plate, resulting in difficult drainage, and at the same time, some liquid will still remain in the solid particles, with low production efficiency and unsatisfactory production effects.

[0022] Compared with the prior art, the present invention provides an organic biogas slurry production device rich in organic matter, having the following beneficial effects:

[0023] 1. For the organic biogas slurry production device rich in organic matter, the driving part drives the connecting rod to reciprocate horizontally on the separation box. The connecting rod drives the rubber hammer to move synchronously through the sliding seat and the guide rod. At the same time, driven by the connecting part, the guide rod reciprocates vertically on the sliding seat, thereby driving the rubber hammer to continuously strike the filter plate up and down, making the filter plate vibrate, preventing fixed particles from blocking the filter plate, making the drainage smoother, and improving the production efficiency and production effect.

[0024] 2. For the organic biogas slurry production device rich in organic matter, by setting an airbag, when the push plate and the baffle return to their original positions, the connecting rod connected to the baffle drives the pressing block to squeeze the airbag, and the gas therein blows from the multiple air outlets of the rubber hammer towards the bottom of the filter plate through the hose and the hollow plate, blowing up the fixed particles blocked in the filter plate, further preventing the filter plate from being blocked.

[0025] 3. For the organic biogas slurry production device rich in organic matter, by starting the second motor, driven by the first spline shaft, the gear, and the first rotating cylinder, the two crushing rollers and two groups of crushing teeth rotate in reverse. At the same time, driven by the second belt drive, the reciprocating lead screw, the slider, the fixed rod, the connecting frame, the limiting ring, the first rotating cylinder, and the first spline shaft, while the two groups of crushing teeth rotate, they also generate relative movement, making the raw materials crushed more thoroughly, reducing the particle size of the larger solid duck manure, ensuring the uniformity of the materials, and being beneficial to the subsequent anaerobic fermentation effect.

[0026] 4. For the organic biogas slurry production device rich in organic matter, by setting a rubber scraper, it can continuously scrape off the duck manure raw materials blocked between the crushing teeth and the crushing roller during crushing. At the same time, driven by the first spline shaft, the crank, the sliding block, the connecting plate, the second spline shaft, and the second rotating cylinder, the rubber scraper continuously swings, improving the effect of scraping off the duck manure raw materials, enabling the duck manure raw materials to be crushed in a timely manner, and having a better crushing effect.

[0038] Embodiment 1:

A hydraulic rod 10 is fixedly connected to the top of the separation box 4, and a pressing plate 7 for squeezing the solid-liquid mixture is fixedly connected to the telescopic end of the hydraulic rod 10. The pressing plate 7 is slidably connected to the inner wall of the separation box 4, and the pressing plate 7 is arranged above the filter plate 6. One side of the separation box 4 is provided with a push plate facing The discharge port 12 of 11 is used to discharge fixed waste. The solid waste can be used as compost raw material, processed by composting equipment, and further converted into decomposed organic fertilizer for use in farmland or other fields. The separation box 4 is provided with a water outlet pipe 21, which is used to discharge filtered organic biogas. The water outlet pipe 21 is connected to an external liquid storage tank. An exhaust pipe is provided on the top of the fermentation tank 1 to transport biogas to a gas storage tank, which can be used directly or for power generation, heat supply and other purposes after purification.

[0040] During operation, the solid-liquid mixture in the fermentation tank 1 is introduced into the separation tank 4 by starting the pump body 9. At this time, the solid-liquid mixture falls on the filter plate 6, and the organic biogas slurry is discharged from the water outlet pipe 21 through the filter plate 6 and enters the storage tank. The hydraulic rod 10 is started, and its telescopic end drives the pressing plate 7 to descend. The pressing plate 7 squeezes the solid-liquid mixture to squeeze out the liquid remaining in the solid particles. Then, the solid fertilizer is discharged from the feeding port 12. After that, the above steps are repeated to finish processing the solid-liquid mixture in the fermentation tank 1. The driving part drives the connecting rod 201 to reciprocate horizontally on the separation tank 4. The connecting rod 201 drives the rubber hammer 303 to move synchronously through the sliding seat 301 and the guide rod 302. At the same time, driven by the connecting part, the guide rod 302 reciprocates vertically on the sliding seat 301, thereby driving the rubber hammer 303 to continuously strike the filter plate 6 up and down, causing the filter plate 6 to vibrate, preventing the fixed particles from blocking the filter plate 6, making the drainage smoother, and improving the production efficiency and production effect.

[0041] The driving part includes a first motor 202 fixedly connected to the outside of the separation tank 4. A threaded rod 203 is rotatably installed on the outside of the separation tank 4 through a bearing. The threaded rod 203 is connected to the output end of the first motor 202 through a first belt drive 204. The first belt drive 204 is mainly composed of a belt and a pulley that cooperate with each other. Among them, a first threaded block 205 is threadedly connected to the threaded rod 203, and the connecting rod 201 is fixedly connected to the first threaded block 205. The connecting part includes a ring 304 fixedly connected to the circumferential surface of the guide rod 302. The ring 304 is used to prevent the guide rod 302 from slipping off the sliding seat 301. The ring 304 is slidably installed inside the sliding seat 301. A spring 305 is fixedly installed between the top of the ring 304 and the inner wall of the sliding seat 301. A bracket 306 is fixedly connected to the guide rod 302. Among them, a roller 307 is rotatably installed on the bracket 306. A fixed plate 308 is fixedly connected between the inner walls of the separation tank 4. The roller 307 is in contact with the top of the fixed plate 308. That is, when the bracket 306 moves, the roller 307 rolls on the fixed plate 308. A protrusion 309 is fixedly connected to the top of the fixed plate 308 and is arranged on the moving path of the roller 307. The number of protrusions 309 is set to 8 - 10, preferably 9. The protrusion 309 is arc-shaped.

[0042] During operation, the first motor 202 is started. The output end thereof drives the threaded rod 203 to rotate through the first belt drive 204. The threaded rod 203 drives the first threaded block 205 to move. The first threaded block 205 drives the connecting rod 201 to slide horizontally on the separation box 4. The connecting rod 201 drives the sliding seat 301 to move synchronously, thereby driving the guide rod 302 and the rubber hammer 303 to move synchronously. The guide rod 302 drives the support 306 to move synchronously. The support 306 drives the roller 307 to roll on the fixed plate 308. After the roller 307 contacts the protrusion 309 and is squeezed by it, the roller 307 moves upward, thereby driving the guide rod 302 to slide upward. The guide rod 302 drives the ring 304 to slide upward and compress the spring 305. After that, the roller 307 leaves the protrusion 309, and the spring 305 resets, causing the ring 304 to drive the guide rod 302 to slide downward. The guide rod 302 continuously slides longitudinally back and forth, thereby driving the rubber hammer 303 to continuously move up and down, so that the rubber hammer 303 continuously moves up and down when moving horizontally to impact the filter plate 6.

[0043] Embodiment 2:

[0044] Referring to Figures 1 - 6 , it is basically the same as Embodiment 1. Furthermore, the specific implementation schemes for discharging the fixed waste from the separation box 4 and blowing air to the bottom of the filter plate 6 are specifically disclosed.

[0045] A push plate 11 is fixedly connected to the connecting rod 201. In the initial state, that is, before the pressing plate 7 presses the solid-liquid mixture, the push plate 11 is on the side away from the feeding port 12 and is in contact with the inner wall of the separation box 4. At this time, the push plate 11 and the pressing plate 7 are misaligned, and no movement interference will occur between them. The push plate 11 is slidably connected to the inner wall of the separation box 4. The bottom of the push plate 11 is in contact with the top of the filter plate 6. A second threaded block 13 is threadedly connected to the threaded rod 203. A connecting rod 14 is fixedly connected to the second threaded block 13. A baffle 15 for blocking the feeding port 12 is fixedly connected to the connecting rod 14. An airbag 17 is installed at the rear side of the separation box 4. Among them, a hose 18 is connected between the airbag 17 and the guide rod 302, and the hose 18 is fixedly connected to the separation box 4. A pressing block 16 for squeezing the airbag 17 is fixedly connected to the connecting rod 14. A hollow plate 19 is fixedly connected between the guide rod 302 and the rubber hammer 303. An air duct communicating with the hose 18 and the hollow plate 19 is opened on the guide rod 302. An air outlet 20 communicating with the hollow plate 19 is opened on the rubber hammer 303. Each rubber hammer 303 is provided with seven air outlets 20, including one vertically arranged air outlet 20 and six inclined and annularly equally spaced air outlets 20.

[0046] During operation, when the rubber hammer 303 moves and impacts the filter plate 6, that is, during the rotation of the threaded rod 203, the connecting rod 201 drives the push plate 11 to push out the fixed waste on the filter plate 6. At the same time, the threaded rod 203 drives the second threaded block 13 to move horizontally. The second threaded block 13 drives the connecting rod 14 to move synchronously, and the connecting rod 14 drives the baffle 15 to move synchronously, opening the material outlet 12. The fixed waste is discharged from the material outlet 12. At the same time, the connecting rod 14 drives the pressing block 16 away from the airbag 17, and the airbag 17 starts to inflate. Then, the first motor 202 is controlled to reverse, and the push plate 11 and the baffle 15 are reset. At this time, the connecting rod 14 drives the pressing block 16 to squeeze the airbag 17, and the gas therein is blown from the multiple air outlets 20 of the rubber hammer 303 to the bottom of the filter plate 6 through the hose 18 and the hollow plate 19, blowing up the fixed particles blocked in the filter plate 6 and further preventing the filter plate 6 from being blocked.

[0047] Embodiment 3:

[0048] Referring to Figures 1 - 2 and Figures 7 - 8 , it is basically the same as Embodiment 2. Further, a specific implementation scheme for crushing duck manure raw materials is specifically disclosed.

[0049] An inlet and an outlet are respectively opened at the top and bottom of the crushing box 5. The crushing box 5 is communicated with the fermentation tank 1 through the outlet. Two symmetrically arranged crushing rollers 23 are rotatably installed inside the crushing box 5 through the first rotating cylinder 22. A set of crushing teeth 24 are arranged on the circumferential surface of the crushing roller 23. The two sets of crushing teeth 24 are arranged staggeredly, and each set of crushing teeth 24 is arranged at equal intervals. Among them, a second motor 25 is fixedly connected to the outside of the crushing box 5. Two first spline shafts 26 are rotatably installed on the crushing box 5. One of the first spline shafts 26 is fixedly connected to the output end of the second motor 25. The two first rotating cylinders 22 are respectively slidably connected to the two first spline shafts 26. Gears 27 are fixedly connected to both of the two first spline shafts 26. The two gears 27 are meshed and connected. Two horizontally arranged reciprocating lead screws 28 are rotatably installed on the crushing box 5. The two reciprocating lead screws 28 are respectively connected to the two first spline shafts 26 through the second belt drive 29. The second belt drive 29 is mainly composed of a pulley and a belt that cooperate with each other. A slider 30 is threadedly connected to the reciprocating lead screw 28. A fixed rod 31 is fixedly connected to the slider 30. Among them, the fixed rod 31 is slidably connected to the crushing box 5. A connecting frame 32 is fixedly connected to the fixed rod 31. The first rotating cylinder 22 and the second rotating cylinder 34 are both rotatably connected to the connecting frame 32. Limiting rings 35 are fixedly connected to both the first rotating cylinder 22 and the second rotating cylinder 34. The limiting rings 35 are rotatably installed inside the connecting frame 32. If the moisture content of the duck manure is too high, the humidity can be adjusted by adding dry matter (such as straw, straw, etc.) to make it reach the suitable range for anaerobic fermentation (usually between 60% and 75%).

[0050] During operation, the second motor 25 is started, and raw materials are put into the crushing box 5. The output end of the second motor 25 drives the first spline shaft 26 connected thereto to rotate, and drives the two first rotating cylinders 22 to rotate reversely through the transmission of the gear 27, thereby driving the two crushing rollers 23 and the two groups of crushing teeth 24 to rotate reversely. At the same time, the reciprocating lead screw 28 is driven to rotate under the transmission of the second belt drive 29. The reciprocating lead screw 28 drives the slider 30 to slide horizontally, and the slider 30 drives the fixed rod 31 to slide horizontally on the crushing box 5. The fixed rod 31 drives the first rotating cylinder 22 to slide horizontally on the first spline shaft 26 through the connecting frame 32 and the limiting ring 35, so that the two groups of crushing teeth 24 generate relative movement while rotating, making the raw material crushing more thorough, reducing the particle size of the larger solid duck manure, ensuring the uniformity of the material, and being beneficial to the subsequent anaerobic fermentation effect.

[0051] Example 4:

[0052] Referring to Figures 7 - 8 , which is basically the same as Example 3. Further, a specific implementation scheme for cleaning the duck manure blocked on the crushing roller 23 is specifically disclosed.

[0053] Two groups of rubber scrapers 39 respectively contacting the two crushing rollers 23 are rotatably installed inside the crushing box 5 through the second rotating cylinder 34. The side of the rubber scraper 39 contacts the crushing teeth 24. The rubber scraper 39 is located above the crushing teeth 24, and the duck manure raw material scraped off by it can continue to be crushed. Two second spline shafts 33 are rotatably installed on the crushing box 5. The two second rotating cylinders 34 are respectively slidably connected to the two second spline shafts 33. A crank 36 is fixedly connected to the first spline shaft 26. A sliding block 37 is rotatably installed on the crank 36. A connecting plate 38 is fixedly connected to the second spline shaft 33. The sliding block 37 is slidably connected to the connecting plate 38.

[0054] During operation, during the process of crushing raw materials, that is, when the crushing teeth 24 and the crushing roller 23 rotate, the rubber scraper 39 continuously scrapes off the duck manure raw materials blocked between the crushing teeth 24 and the crushing roller 23, so that this part of the raw materials can continue to be crushed. At the same time, the first spline shaft 26 drives the crank 36 to rotate, and the crank 36 drives the sliding block 37 to slide on the connecting plate 38, and the connecting plate 38 continuously swings. Then, the rubber scraper 39 is driven to continuously swing through the second spline shaft 33 and the second rotating cylinder 34, improving the effect of scraping off the duck manure raw materials, enabling the duck manure raw materials to be crushed in time, and having a better crushing effect. And through the transmission of the connecting frame 32 and the limiting ring 35, the second rotating cylinder 34 and the rubber scraper 39 are driven to continuously slide on the second spline shaft 33, so that the rubber scraper 39 can move synchronously with the crushing roller 23, avoiding movement interference between the rubber scraper 39, the crushing roller 23 and the crushing teeth 24.

[0055] An organic biogas slurry production process rich in organic matter has the following operating steps:

[0056] Step 1: Put the duck manure raw material into the crushing box 4, and crush the duck manure through two groups of crushing teeth 24 in the crushing box 4;

[0057] Step 2: After being crushed, the duck manure falls into the fermentation tank 1 for anaerobic fermentation to produce biogas and organic biogas slurry;

[0058] Step 3: Pass the solid-liquid mixture into the separation box 5 through the pump body 9, and carry out solid-liquid separation by using the pressing plate 7 and the filter plate 6. The organic biogas slurry is collected in the storage tank through the water outlet pipe 21;

[0059] Step 4: Open the feeding port 12 through the baffle 15, and push the fixed particles out of the separation box 5 through the push plate 11 from the feeding port 12;

[0060] Step 5: Continuously hit the filter plate 6 with the rubber hammer 303, and pass gas into the rubber hammer 303 through the air bag 17 and blow it towards the filter plate 6.

[0061] For this organic biogas slurry production equipment rich in organic matter, start the second motor 25, put the raw material into the crushing box 5. The output end of the second motor 25 drives the first spline shaft 26 connected to it to rotate, and drives two first rotating cylinders 22 to reverse through the transmission of the gear 27, thereby driving two crushing rolls 23 and two groups of crushing teeth 24 to reverse. At the same time, drive the reciprocating lead screw 28 to rotate under the transmission of the second belt drive 29. The reciprocating lead screw 28 drives the slider 30 to slide horizontally. The slider 30 drives the fixed rod 31 to slide horizontally on the crushing box 5. The fixed rod 31 drives the first rotating cylinder 22 to slide horizontally on the first spline shaft 26 through the connecting frame 32 and the limiting ring 35, thereby driving the two groups of crushing teeth 24 to rotate and generate relative movement at the same time, making the raw material crushing more thorough, reducing the particle size of the larger solid duck manure, and at the same time, the rubber scraper 39 continuously scrapes off the duck manure raw material blocked between the crushing teeth 24 and the crushing roll 23, so that this part of the raw material continues to be crushed. At the same time, the first spline shaft 26 drives the crank 36 to rotate, the crank 36 drives the sliding block 37 to slide on the connecting plate 38, the connecting plate 38 continuously swings, and then drives the rubber scraper 39 to continuously swing through the second spline shaft 33 and the second rotating cylinder 34, improving the effect of scraping off the duck manure raw material, enabling the duck manure raw material to be crushed in time, and having a better crushing effect;

[0062] The crushed raw materials fall into the fermentation tank 1 for anaerobic fermentation. In an anaerobic environment, microorganisms begin to decompose the organic matter in the duck manure, producing methane (biogas) and organic liquid. The fermentation process can last for several weeks. After the fermentation is completed, the pump body 9 is started to introduce the solid-liquid mixture in the fermentation tank 1 into the separation box 4. At this time, the solid-liquid mixture falls on the filter plate 6, and the organic biogas slurry is discharged from the water outlet pipe 21 through the filter plate 6 and enters the storage tank. The hydraulic rod 10 is started, and its telescopic end drives the pressing plate 7 to descend. The pressing plate 7 squeezes the solid-liquid mixture to squeeze out the liquid remaining in the solid particles. Then, the pressing plate 7 is controlled to rise, and the first motor 202 is started. The output end of the first motor 202 drives the threaded rod 203 to rotate through the first belt drive 204. The threaded rod 203 drives the first threaded block 205 to move. The first threaded block 205 drives the connecting rod 201 to slide horizontally on the separation box 4. The connecting rod 201 drives the push plate 11 to push out the fixed waste on the filter plate 6. At the same time, the threaded rod 203 drives the second threaded block 13 to move horizontally. The second threaded block 13 drives the connecting rod 14 to move synchronously. The connecting rod 14 drives the baffle 15 to move synchronously to open the feeding port 12. The fixed waste is discharged from the feeding port 12. At the same time, the connecting rod 201 drives the sliding seat 301 to move synchronously, thereby driving the guide rod 302 and the rubber hammer 303 to move synchronously. The guide rod 302 drives the bracket 306 to move synchronously. The bracket 306 drives the roller 307 to roll on the fixed plate 308. After the roller 307 contacts the protrusion 309 and is squeezed by it, the roller 307 moves upward, thereby driving the guide rod 302 to slide upward. The guide rod 302 drives the ring 304 to slide upward and compress the spring 305. Then, the roller 307 leaves the protrusion 309, and the spring 305 resets, causing the ring 304 to drive the guide rod 302 to slide downward. The guide rod 302 continuously slides longitudinally back and forth, thereby driving the rubber hammer 303 to move up and down continuously, so that the rubber hammer 303 moves up and down continuously when moving horizontally and impacts the filter plate 6. Then, the first motor 202 is controlled to rotate in the reverse direction, and the push plate 11 and the baffle 15 are reset. At this time, the connecting rod 14 drives the pressing block 16 to squeeze the airbag 17, and the gas in it passes through the hose 18 and the hollow plate 19 and is blown from the plurality of air outlets 20 of the rubber hammer 303 to the bottom of the filter plate 6 to blow up the fixed particles blocked in the filter plate 6, further preventing the filter plate 6 from being blocked.
