Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a container-type dry anaerobic fermentation device. Background Art

[0002] Biogas technology includes preparation and high-value utilization technology. Biogas preparation technology mainly includes wet fermentation technology and dry fermentation technology. Wet fermentation technology is a traditional technology and is widely used in European biogas projects. The representative process technology is the completely mixed anaerobic fermentation process (CSTR) of Envitec and MT in Germany. Dry anaerobic fermentation technology has the characteristics of strong raw material adaptability, large processing load, low equipment investment, low process energy consumption and no wastewater discharge. It has gradually become the main development direction of the industry in Europe. Representative processes include German Bioferm and GICON processes, French SPI company's leachate reflux dry anaerobic fermentation technology and VALORGA process and Swedish Kompogas process. Germany and some other European countries mainly use dry fermentation to treat urban organic waste. The technology of French SPI can adapt to a variety of materials such as aquaculture waste, straw and organic waste, which is more in line with my country's national conditions and is one of the key technologies of the domestic biogas industry. After investigation, small-scale dry anaerobic fermentation equipment has products abroad, but no mature industrial products have been seen in China. Foreign dry fermentation technology and equipment are mainly Laran process or Kompogas process, mostly horizontal drum continuous dry fermentation, and domestic small-scale anaerobic fermentation equipment is mainly wet anaerobic fermentation equipment and household concrete biogas tanks. The leachate reflux dry anaerobic fermentation technology and drum dry process of SPI of France are more advanced than the traditional wet process. Compared with the drum dry process, the garage type has higher convenience, lower cost, more stable operation and higher gas production rate. Although leachate reflux dry anaerobic fermentation has great advantages, the leachate reflux dry anaerobic fermentation technology of SPI of France is an engineering technology, which is characterized by large-scale and large-scale. It is applicable to large-scale farms, garbage treatment plants, and agricultural processing waste treatment. It cannot meet the needs of small-scale application scenarios of small-scale farms, township garbage, farms, reed straw treatment, large supermarkets, and schools.

[0003] For example, China's authorized patent, a containerized dry anaerobic fermentation device (application number: 202310797797.1), discloses a containerized dry anaerobic fermentation device, including an anaerobic fermentation system, a filtrate reflux system and a control system. The anaerobic fermentation system of the containerized dry anaerobic fermentation device is integrated in a closed box, and the control system is integrated in a control cabinet. The filtrate reflux system is an integrated device; the anaerobic fermentation system, the filtrate reflux system or the control system are connected by pipelines or circuits; the containerized dry anaerobic fermentation device includes at least one anaerobic fermentation system, through the integrated setting of the anaerobic fermentation system, the filtrate reflux system and the control system. During use, the anaerobic fermentation system, filtrate reflux system and control system can be transported to a designated location by vehicle, and then the various systems can be connected through pipelines and circuits. It does not require a lot of engineering construction and has the advantages of easy use and installation. The integrated system can be miniaturized, which meets the needs of miniaturized application scenarios. However, there is a problem that only a forklift is used to load and empty materials. The forklift is prone to miss materials scattered at the corners due to looseness. In addition, since the box is fixed, it is difficult to clean the materials in the corners, resulting in waste left in the box, which in turn forms sediment blocks, affecting the seepage reflux efficiency, and then affecting the fermentation efficiency. Therefore, a container-type dry anaerobic fermentation device is proposed to address the above problems. Summary of the invention

[0004] In order to make up for the shortcomings of the prior art and solve the problem that when only a forklift is used to load and empty materials, the forklift is prone to miss materials scattered at the corners due to looseness. In addition, since the box is fixed, it is also difficult to clean the materials in the corners, resulting in waste materials left in the box, which further forms sediment blocks, affects the seepage reflux efficiency, and further affects the fermentation efficiency. The present invention proposes a containerized dry anaerobic fermentation device.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: a container-type dry anaerobic fermentation device described in the present invention comprises a container body; a gate is arranged on one side of the container body, a water spray pipe is fixedly installed on the inner wall at the top of the container body, a biogas collection pipe is fixedly installed on one side of the water spray pipe, the biogas collection pipe is fixedly installed on the inner wall of the container body, the inner wall at the bottom of the container body is evenly provided with filtering and draining ports, and a transport component is arranged on one side of the container body; through the provided transport component and scraping component, when filling and emptying materials, the materials can be placed in the bucket, the materials are transported into and out of the container body through the transport component, and the fallen materials are removed through the scraping component The dust at the bottom of the container body is scraped off to prevent the formation of lumps at the bottom of the container body, and the filling and emptying of materials by a forklift is avoided. The forklift is easy to miss the materials scattered at the corners due to looseness. In addition, because the box body is fixed, it is difficult to clean the materials in the corners, which will leave waste in the box and form sediment blocks, affecting the efficiency of the seepage return and the fermentation efficiency. The scattered dust will not accumulate in the corners of the container body and the bottom of the container body will not clump, which improves the fermentation effect of the device during long-term operation. In addition, the use of a truck to carry materials in and out can also simplify the loading process, make the material laying more even, improve the penetration effect of the return liquid, and thus increase the biogas production.

[0006] Preferably, the transport component includes a motor, a bucket, a first sliding groove, a first sliding block and a screw rod, a motor is fixedly mounted on one side of the container body, a screw rod is fixedly mounted on the output end of the motor, the screw rod is embedded in the inner wall of the first sliding groove, the first sliding groove is opened on the inner wall of the container body, the outer wall of the screw rod is threadedly connected with the first sliding block, the first sliding block is embedded in the inner wall of the first sliding groove, and the first sliding block is slidably connected with the first sliding groove, a bucket is fixedly mounted on one side of the first sliding block, a separation component is arranged at the bottom end of the bucket, and a scraping component is arranged on the side of the bucket close to the filter and sewage outlet; by arranging the transport component, when biogas fermentation starts, the material is evenly filled in the bucket The inner wall of the container is started, and the motor is started. The motor drives the screw rod to rotate, and the screw rod drives the first sliding block to move away from the gate. The first sliding block drives the bucket to move, and the material is sent into the container. The gate is closed again to start fermentation. After the biogas production is completed, the gate is opened, and the motor is started to drive the bucket to move toward the gate to bring the material out of the container. This avoids the problem that when only a forklift is used to transport materials, the loose materials are easily scattered and the soil is sunk in the corners of the container. The soil is not easy to clean and will gradually form lumps, affecting the subsequent fermentation process. The material is placed in the bucket for transportation, and dust will not be scattered at the corners of the container, so that no residual material will appear in the container, which improves the subsequent fermentation efficiency. In addition, it can also make the filling and transportation of materials easier.

[0007] Preferably, the separation component includes a first fence plate, a second fence plate, a blocking plate, a first spring, a support plate and a through hole, the first fence plate is installed at the bottom end of the vehicle bucket, the second fence plate is slidably installed at the bottom end of the first fence plate, the top of the second fence plate is opened with a through hole, the bottom end of the inner wall of the through hole is provided with an anti-stuck component, the bottom end of the second fence plate is installed with a support plate, the support plate is fixedly installed on the inner wall of the vehicle bucket near the gate, the first spring is evenly installed on one end of the second fence plate near the gate, and the end of the first spring away from the second fence plate is installed on the inner wall of the vehicle bucket near the gate; by setting the separation component, when the vehicle bucket completes carrying and stops moving, the blocking plate abuts against the second fence plate and blocks the movement of the second fence plate, so that the second fence plate A gap is created between the guardrail and the first fence plate, so that the filtrate produced by the microorganisms can penetrate and flow out. When the truck bed starts to move toward the gate, the second fence plate is no longer blocked by the blocking plate, and the first spring releases its elastic potential energy to push the second fence plate to reset, thereby forming a closed structure between the second fence plate and the first fence plate, preventing loose materials from falling into dust and passing through the first and second fence plates to fall into the bottom of the container body, thereby avoiding the problem that the liquid produced during the fermentation and production of biogas by microorganisms is deposited at the bottom of the truck bed, affecting the growth of microorganisms and causing a decrease in biogas output. The liquid produced by the microorganisms can seep out of the bottom of the truck bed and flow down to the bottom of the container body, so that the growth of the microorganisms is not affected by the liquid, thereby increasing the biogas production.

[0008] Preferably, the positions of the first fence plate and the second fence plate are staggered with each other; by arranging the positions of the first fence plate and the second fence plate to be staggered with each other, when the truck bed moves, the first fence plate and the second fence plate form a closed structure, thereby preventing loose materials from dropping dust, passing through the first fence plate and the second fence plate and falling into the bottom of the container body, and forming lumps at the bottom of the container body under the influence of the material liquid, thereby affecting the seepage reflux efficiency. The dust that falls when the truck bed moves will not fall to the bottom of the container body, thereby improving the seepage reflux efficiency and thereby improving the efficiency of biogas production.

[0009] Preferably, the anti-stuck component includes a rotating groove, a rotating plate and a second spring, a rotating groove is opened at the bottom end of the inner wall of the through hole, the rotating groove is opened on the outer wall of the second fence plate, the inner wall of the rotating groove is installed with a second spring, and the rotating plate is installed at one end of the second spring; by setting the anti-stuck component, when particles hinder the closing of the first fence plate and the second fence plate, the rotating plate is pushed by the particles and rotates toward the rotating groove, so that the particles fall to the bottom of the bucket, and after the particles fall, the rotating plate is no longer pushed by the particles, and the second spring releases elastic potential energy to push the rotating plate to reset, thereby avoiding the first fence plate and the second fence plate from closing. When the second fence plates cannot be closed due to particles, the first fence plates and the second fence plates maintain a staggered structure and move toward the gate, so that the loose materials continue to scatter dust, and the dust passes through the first fence plates and the second fence plates and falls to the bottom of the container body, forming lumps, affecting the flow rate of the seepage liquid, affecting the subsequent seepage liquid return efficiency, and further affecting the growth of microorganisms, resulting in a reduction in biogas production. When the first fence plates and the second fence plates cannot be closed due to particles, the particles can pass through, thereby completing the closed structure and preventing dust from falling, thereby improving the subsequent seepage liquid return efficiency and further increasing the biogas production.

[0010] Preferably, the scraping assembly comprises a rotating scraping block, a rotating rod, a lifting block, a lifting slot, and a fixed scraping block. The lifting slot is evenly opened on one side of the bucket near the filter and sewage outlet, and the lifting block is slidably installed on the inner wall of the lifting slot. The bottom ends of both ends of the lifting block are provided with fixed scraping blocks, and rotating scraping blocks are evenly arranged between the fixed scraping blocks. The middle part of the rotating scraping block and the top of the fixed scraping block are fixedly installed with a rotating rod, and the top of the rotating rod is rotatably installed on the lower end of the lifting block. A sliding assembly is arranged on one side of the fixed scraping block, and a filtering assembly is arranged on the top of the rotating scraping block. By arranging the scraping assembly, when there is soil and dust When the soil lumps scattered on the bottom of the container body are formed, the bucket is moved, the bucket drives the lifting block to move, the lifting block drives the rotating rod to move, and the rotating rod drives the rotating scraper block and the fixed scraper block to move, so that the rotating scraper block and the fixed scraper block scrape off the lumps attached to the bottom of the container body, thereby avoiding the problem of continuous accumulation of lumps on the bottom of the container body due to long-term use of the device, affecting the seepage return efficiency, and then affecting the microbial growth rate, resulting in a decrease in biogas output. The bucket can be moved while driving the scraper assembly to scrape off the soil lumps on the bottom of the container body, thereby improving the seepage return efficiency, thereby increasing the microbial growth rate, and then increasing the biogas output.

[0011] Preferably, an inclined slope is provided at the bottom of the container body, and one end of the inclined slope close to the filter sewage outlet is set as a horizontal part, and one end of the inclined slope close to the gate is set as an inclined part; by providing the inclined slope at the bottom of the container body, when microorganisms produce biogas and liquid, the liquid permeates the material, passes through the first fence plate and the second fence plate, falls on the inclined slope, and is collected at the horizontal part of the inclined slope through the inclined part of the inclined slope, and flows out from the filter sewage outlet, thereby preventing the infiltrated liquid from being deposited at the bottom of the container body and the seepage liquid outflow rate from being low, resulting in a decrease in the seepage liquid reflux efficiency, thereby affecting the biogas output, and increasing the liquid outflow rate, thereby increasing the seepage liquid reflux efficiency, and increasing the biogas output. In addition, the horizontal part of the inclined slope also provides a rotating space for the rotating scraper block, so that the rotating scraper block can form a screen structure.

[0012] Preferably, the sliding assembly includes a second sliding groove and a second sliding block, and one side of the fixed scraper block is fixedly installed with a second sliding block, and the second sliding block is slidably installed on the inner wall of the second sliding groove, and the second sliding groove is opened on the inner wall of the container body, and the inclination angle of the second sliding groove is the same as the inclined slope. By setting the sliding assembly, when the scraper assembly scrapes and cleans the bottom of the container body, the second sliding groove limits the second sliding block, and the second sliding block limits the scraper assembly again, so that the rotating scraper block and the bottom end of the fixed scraper block are always in contact with the inclined slope when facing a relatively firm agglomeration, so that the scraper assembly is prevented from lifting up and sweeping over the agglomeration when facing a relatively firm agglomeration, leaving the agglomeration residual, thereby affecting the subsequent seepage reflux rate, affecting the growth of microorganisms, and causing the problem of reduced biogas production efficiency, so that the lower ends of the rotating scraper block and the fixed scraper block are always in contact with the inclined slope for movement, so that the scraper assembly can better scrape off the agglomeration at the bottom of the container body, thereby improving the seepage reflux efficiency, and thus improving the biogas production.

[0013] Preferably, the filter assembly includes a gear and a rack, a gear is fixedly installed on the top of the lifting block, the gear is fixedly installed on the outer wall of the rotating rod, a rack is meshingly installed on one side of the gear, and the end of the rack away from the gear is fixedly installed on the inner wall of the container body; by setting the filter assembly, when the first fence plate and the second fence plate form a fence structure, the rack can drive the gear to rotate, and the gear then drives the rotating rod to rotate, and the rotating rod drives the rotating scraper block to rotate, so that the rotating scraper block forms a screen structure, which avoids the rotating scraper block blocking the collected liquid from flowing out of the filter outlet, so that the seepage cannot flow back, resulting in a slow growth rate of microorganisms and causing low biogas output. The scraper assembly can form a screen filter structure during biogas production, so that the liquid formed during biogas production can flow out through the filter outlet, and the seepage can flow back, thereby increasing the growth rate of microorganisms and thus increasing the output of biogas.

[0014] Preferably, the distance between adjacent rotating rods is greater than the distance between the two sides of the rotating scraper block; by setting the spacing between adjacent rotating rods to be greater than the distance between the two sides of the rotating scraper block, a gap can be left for the slurry to flow through when the rotating scraper block forms a screen structure.

[0015] The present invention is beneficial in that:

[0016] 1. The present invention sets a transport component. When biogas fermentation starts, the material is evenly filled on the inner wall of the bucket, the motor is started, the motor drives the screw rod to rotate, the screw rod drives the first sliding block to move away from the gate, the first sliding block drives the bucket to move, the material is sent into the container, the gate is closed, the fermentation starts, and after the biogas production is completed, the gate is opened, the motor is started to drive the bucket to move toward the gate, and the material is taken out of the container. This avoids the problem that when only a forklift is used to transport materials, the loose materials are easily scattered and the soil is sunk in the corners of the container. The soil is not easy to clean and will gradually form agglomerates, which affects the subsequent fermentation process. When the materials are placed in the bucket for transportation, dust will not be scattered at the corners of the container, and residual materials will not appear in the container, thereby improving the subsequent fermentation efficiency. In addition, the filling and transportation of materials can be made simpler.

[0017] 2. The present invention sets a scraper assembly. When dust is scattered on the bottom of the container body and forms lumps, the bucket is moved, the bucket drives the lifting block to move, the lifting block drives the rotating rod to move, and the rotating rod drives the rotating scraper block and the fixed scraper block to move, so that the rotating scraper block and the fixed scraper block scrape off the lumps attached to the bottom of the container body, thereby avoiding the problem that the bottom of the container body accumulates lumps continuously due to long-term use of the device, affecting the seepage reflux efficiency, and further affecting the microbial growth rate, resulting in a decrease in biogas output. The bucket can be moved while driving the scraper assembly to scrape off the soil lumps at the bottom of the container body, thereby improving the seepage reflux efficiency, thereby improving the microbial growth rate, and further improving the biogas output.

[0040] See also Fig.10 As shown, an inclined slope 27 is provided at the bottom of the container body 1, and one end of the inclined slope 27 close to the filter sewage outlet 5 is set as a horizontal part, and one end of the inclined slope 27 close to the gate 2 is set as an inclined part; by providing the inclined inclined slope 27 at the bottom of the container body 1, when microorganisms produce biogas and liquid, the liquid penetrates the material, passes through the first fence plate 11 and the second fence plate 12, falls on the inclined slope 27, and is collected at the horizontal part of the inclined slope 27 through the inclined part of the inclined slope 27, and flows out from the filter sewage outlet 5, thereby preventing the infiltrated liquid from being deposited at the bottom of the container body 1, and the seepage liquid outflow rate is low, resulting in a decrease in the seepage liquid reflux efficiency, thereby affecting the biogas output, and increasing the liquid outflow rate, thereby increasing the seepage liquid reflux efficiency, and increasing the biogas output. In addition, the horizontal part of the inclined slope 27 also provides a rotating space for the rotating scraper block 21, so that the rotating scraper block 21 can form a screen structure.

[0041] See also Figure 7 , 8As shown in Figure 10, the sliding assembly includes a second sliding groove 19 and a second sliding block 20. The second sliding block 20 is fixedly installed on one side of the fixed scraping block 28. The second sliding block 20 is slidably installed on the inner wall of the second sliding groove 19. The second sliding groove 19 is opened on the inner wall of the container body 1. The inclination angle of the second sliding groove 19 is the same as the inclined slope 27. By setting the sliding assembly, when the scraping assembly scrapes and cleans the bottom of the container body 1, the second sliding groove 19 limits the second sliding block 20, and the second sliding block 20 then moves the scraping assembly. The limit position makes the bottom ends of the rotating scraper block 21 and the fixed scraper block 28 always abut against the inclined slope 27, avoiding the problem that when the scraper assembly faces a relatively firm agglomerate, the scraper assembly is lifted up and passes over the agglomerate, causing the agglomerate to remain, thereby affecting the subsequent seepage return rate, affecting the growth of microorganisms, and causing a decrease in biogas production efficiency. The lower ends of the rotating scraper block 21 and the fixed scraper block 28 are always moved in contact with the inclined slope 27, so that the scraper assembly can better scrape off the agglomerates at the bottom of the container body 1, thereby improving the seepage return efficiency and further increasing the biogas production.

[0042] See also Figure 7-11 As shown, the filtering assembly includes a gear 22 and a rack 23, the top of the lifting block 25 is fixedly installed with a gear 22, the gear 22 is fixedly installed on the outer wall of the rotating rod 24, one side of the gear 22 is meshingly installed with a rack 23, and the end of the rack 23 away from the gear 22 is fixedly installed on the inner wall of the container body 1; by setting the filtering assembly, when the first fence plate 11 and the second fence plate 12 form a fence structure, the rack 23 can drive the gear 22 to rotate, and the gear 22 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the rotating scraper block 21 to rotate, so that the rotating scraper block 21 forms a screen structure, avoiding the rotating scraper block 21 blocking the collected liquid from flowing out of the filtering sewage outlet 5, so that the seepage cannot flow back, resulting in a slow growth rate of microorganisms and causing low biogas output. The scraper assembly can form a screen filtering structure during biogas production, so that the liquid formed during biogas production can flow out through the filtering sewage outlet 5, and the seepage can flow back, thereby increasing the growth rate of microorganisms and thus increasing the output of biogas.

[0043] See also Figure 7-11 As shown, the distance between adjacent rotating rods 24 is greater than the distance between the two sides of the rotating scraper block 21; by setting the spacing between adjacent rotating rods 24 to be greater than the distance between the two sides of the rotating scraper block 21, a gap can be left for the liquid to flow through when the rotating scraper block 21 forms a screen structure.

[0044] Working principle: when starting dry anaerobic fermentation, fill the material evenly into the bucket 7, start the motor 6, the motor 6 drives the screw 10 to rotate, the screw 10 drives the first sliding block 9 to move toward the filter sewage outlet 5, and the first sliding block 9 drives the bucket 7 to move. When the bucket 7 is completely placed inside the container body 1, turn off the motor 6, close the gate 2, form a closed fermentation space, fermentation is carried out, and the generated biogas is collected by the biogas collection pipe 4.

[0045] When the microorganisms produce biogas and liquid, and the liquid needs to seep out of the material, the blocking plate 13 abuts against the second fence plate 12 to block the movement of the second fence plate 12, so that a gap is generated between the second fence plate 12 and the first fence plate 11, allowing the filtrate produced by the microorganisms to seep out.

[0046] When the slurry flows down to the bottom of the container body 1 and needs to flow out of the container body 1 through the filter drain port 5, the slurry is collected on one side of the rotating scraper block 21 through the inclined slope 27. At the same time, the rack 23 drives the gear 22 to rotate, and the gear 22 drives the rotating rod 24 to rotate. The rotating rod 24 drives the rotating scraper block 21 to rotate, so that the rotating scraper block 21 forms a screen structure, so that the slurry can flow out of the container body 1 through the filter drain port 5, and the filtrate is refluxed, and the material is sprayed through the water spray pipe 3 to replenish the moisture required for the growth of microorganisms.

[0047] When the biogas production is completed and the materials need to be transported out for clearing, the gate 2 is opened and the motor 6 is started, so that the motor 6 drives the screw rod 10 to rotate, and the screw rod 10 drives the first sliding block 9 to move toward the gate 2, and the gate 2 drives the bucket 7 to move. At this time, the blocking plate 13 cancels the blocking of the second fence plate 12, and the first spring 14 releases the elastic potential energy to push the second fence plate 12 to reset, so that a closed structure is formed between the second fence plate 12 and the first fence plate 11 to prevent the loose materials from falling into the dust and scattering on the container body 1. The bottom of the container body 1 is formed by the rack 23 driving the gear 22 to rotate, the gear 22 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the rotating scraper block 21 to rotate, so that the rotating scraper block 21 and the fixed scraper block 28 form a closed structure, and the second sliding block 20 is limited by the second sliding groove 19, and the second sliding block 20 limits the scraping assembly, so that the lower ends of the rotating scraper block 21 and the fixed scraper block 28 always fit the inclined slope 27 to move, so as to remove the dust and lumps scattered on the bottom of the container body 1.

[0048] When particles appear and hinder the closing of the first fence plate 11 and the second fence plate 12, the rotating plate 17 is pushed by the particles and rotates toward the rotating groove 16, causing the particles to fall to the bottom of the bucket 7. After the particles fall, the rotating plate 17 is no longer pushed by the particles, and the second spring 18 releases its elastic potential energy, pushing the rotating plate 17 to return to its original position, so that the first fence plate 11 and the second fence plate 12 can successfully complete the closing structure.
