Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically to an anaerobic fermentation sealing device. Background Technology

[0002] Anaerobic fermentation is a process in which organic matter is converted into biogas (mainly composed of methane and carbon dioxide) and bio-fertilizer through the metabolic activities of microorganisms under anaerobic conditions. This technology is widely used in agricultural waste treatment, sewage treatment, and biomass energy development. The sealing device, as a core component of the anaerobic fermentation system, directly affects fermentation efficiency, gas production stability, and safety.

[0003] The related technology (publication number: CN208327865U) discloses an anaerobic fermenter. The disclosed technical solution is as follows: a heating device is installed inside the fermenter. The heating device generates heat. The heat can be prevented from dissipating quickly through the heat insulation layer of the tank body. The heat is also transferred into the interior of the fermenter through the tank wall. During fermentation, the temperature rises rapidly and can be maintained inside the fermenter, thereby reducing the composting production cycle and improving work efficiency.

[0004] The above-disclosed technical solutions reveal the following problems: In the anaerobic fermentation process, sealing is the core prerequisite for ensuring the success of the reaction. Its importance lies in its comprehensive impact on microbial activity, product efficiency, safety, and system stability. Therefore, to ensure the airtightness of the anaerobic fermentation vessel, we propose an anaerobic fermentation sealing device.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of fermentation sealing in the prior art, this utility model provides an anaerobic fermentation sealing device that uses a fermentation dish locking structure combined with a push-sealing structure to achieve the fermentation sealing effect. Its specific technical solution is as follows:

[0007] An anaerobic fermentation sealing device includes a base, a top frame fixed to the side wall of the base, a pushing assembly facing the base on the top frame, a sealing pressure member on the pushing end of the pushing assembly, a suction cup embedded in the bottom of the sealing pressure member, and an adsorption driving member on the sealing pressure member to create a negative pressure in the inner cavity of the suction cup. A sealing chamber is fixed to the top of the base, and sliding rods are uniformly arranged through the circumferential outer wall of the sealing chamber. A locking assembly is provided on the base to drive all sliding rods to retract and extend simultaneously.

[0008] In the above technical solution, the locking assembly includes a support column fixed between the sealed chamber and the base, a linkage gear sleeved on the outer wall of the support column, a support shaft located on the outer periphery of the sealed chamber and rotatably mounted on the top of the base, a transmission gear meshing with the linkage gear sleeved on the outer wall of the support shaft, a force-bearing member fixedly mounted on the end of the slide rod outside the sealed chamber, a cam sleeved on the outside of the support shaft and fitted against the outer side of the force-bearing member, and a drive gear meshing with the linkage gear on the base.

[0009] An elastic element is provided between the force-bearing component and the outer wall of the sealed chamber, and is sleeved on the outer wall of the slide rod.

[0010] A buffer block is fixed to the end of the slide rod located inside the sealed chamber.

[0011] Ball bearings are evenly arranged circumferentially between the linkage gear and the support column.

[0012] The adsorption driving component includes a support cylinder fixed to the top of the sealing pressure member, and the support cylinder is fixed to the top of the suction cup. A piston is slidably provided on the inner wall of the support cylinder. A threaded rod that is threadedly connected to the support cylinder is fixed to the top of the piston, and the threaded rod extends out of the outside of the support cylinder. An exhaust hole is provided at the top of the support cylinder.

[0013] The pushing assembly includes a threaded post that is threadedly connected to the top frame, with the bottom end of the threaded post rotatably disposed on top of the sealing pressure member.

[0014] The bottom end of the threaded column is fixedly connected to an outer cover, and the top of the sealing pressure member is fixedly connected to a movable member embedded in the inner cavity of the outer cover.

[0015] The top of the sealing pressure member is fixedly connected to a guide rod parallel to the threaded post, the guide rod passing through the inner cavity of the top frame and extending to the outside.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the anaerobic fermentation sealing device:

[0017] 1. After placing the fermentation vessel inside the sealed chamber, the locking assembly causes all the circumferential sliding rods to slide simultaneously toward the center. The position of the fermentation vessel is locked by the inner ends of the five circumferential sliding rods. The sliding position of the sliding rods can be adjusted according to the specifications of the fermentation vessel, thus making it suitable for fixing fermentation vessels of different specifications, ensuring the stability of the sealing process, and thus ensuring the airtightness of the fermentation process.

[0018] 2. The sealing cap of the fermentation vessel is attached to the bottom of the sealing pressure component. Then, the suction driving component creates a negative pressure in the inner cavity of the suction cup, fixing the sealing cap of the fermentation vessel to the bottom of the sealing pressure component. By attaching and fixing the sealing cap, the position of the sealing cap is prevented from shifting, thus ensuring the sealing performance when connected to the fermentation vessel.

[0019] Third, the sealing pressure component causes the sealing cap at the bottom to move towards the fermentation vessel through the pushing component. During the application of pressure, the sealing cap is fixed to the fermentation vessel with bolts, thereby ensuring the sealing of the inner cavity of the fermentation vessel and preventing air leakage from the fermentation vessel during the fermentation process.

[0020] Fourth, after the fermentation vessel is covered with a sealing cap, the output shaft of the motor, which can be adjusted to rotate in both directions, drives the drive gear to rotate in the opposite direction, causing the cam to move away from the surface of the force-bearing component along with the support shaft. At this time, the elastic force of the elastic component is used to reset the slide bar, making the operation of removing the fermentation vessel more convenient. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0028] An anaerobic fermentation sealing device includes a base 1, a top frame 2 fixedly connected to the side wall of the base 1, and a top frame 2 parallel to the base 1, fixedly installed on the circumferential outer wall of the base 1 via a longitudinal frame. A pushing assembly facing the base 1 is provided on the top frame 2, and a sealing pressure member 3 is provided at the pushing end of the pushing assembly. The pushing assembly is longitudinally oriented towards the sealing chamber 5, ensuring that the sealing pressure member 3 and the sealing chamber 5 are on the same vertical line. A suction cup 4 is embedded in the bottom of the sealing pressure member 3, and an adsorption driving member is provided on the sealing pressure member 3 to create a negative pressure inside the suction cup 4. Two through holes penetrating the inner cavity are opened at the bottom of the sealing pressure member 3, and the suction cup 4 is fixedly embedded in the through holes, with the bottom of the suction cup 4 and the bottom of the sealing pressure member 3 on the same plane.

[0029] A sealing chamber 5 is fixedly attached to the top of the base 1. Sliding rods 6 are evenly distributed through the circumferential outer wall of the sealing chamber 5, and a locking assembly is provided on the base 1 to simultaneously retract all the sliding rods 6. The sealing chamber 5 is securely fixed to the top of the base 1, and five sliding rods 6 are arranged circumferentially around the center of the sealing chamber 5. The sliding rods 6 slide within the through holes in the side wall of the sealing chamber 5. After the fermentation vessel is placed inside the sealing chamber 5, the locking assembly causes all the circumferential sliding rods 6 to slide simultaneously towards the center. The inner ends of the five circumferential sliding rods 6 lock the position of the fermentation vessel. The sliding position of the sliding rods 6 can be adjusted according to the specifications of the fermentation vessel, thus adapting to the fixing of fermentation vessels of different sizes, ensuring the stability of the sealing process, and consequently ensuring the sealing of the fermentation process.

[0030] Then, the sealing cap of the fermentation vessel is attached to the bottom of the sealing pressure component 3. Then, the suction driving component creates a negative pressure in the inner cavity of the suction cup 4, which fixes the sealing cap of the fermentation vessel to the bottom of the sealing pressure component 3. By attaching and fixing the sealing cap, the position of the sealing cap is prevented from shifting, thus ensuring the sealing performance of the connection with the fermentation vessel.

[0031] Then, the sealing pressure component 3 is pushed by the pushing component to move the bottom sealing cover towards the fermentation vessel. During the application of pressure, the sealing cover is fixed to the fermentation vessel by bolts, thereby ensuring the sealing of the inner cavity of the fermentation vessel and preventing air leakage from the fermentation vessel during the fermentation process.

[0032] The locking assembly includes a support column 22 fixed between the sealed chamber 5 and the base 1. A linkage gear 15 is sleeved on the outer wall of the support column 22. A support shaft 27 is rotatably mounted on the top of the base 1, located on the outer periphery of the sealed chamber 5. A transmission gear 14, meshing with the linkage gear 15, is sleeved on the outer wall of the support shaft 27. The top of the support column 22 is vertically fixed to the bottom of the sealed chamber 5, and the bottom of the support column 22 is vertically fixed to the top of the base 1. The linkage gear 15 is sleeved on the outer wall of the support column 22, allowing it to rotate on the outer wall of the support column 22. Bearings are sequentially embedded circumferentially on the top of the base 1, and the bottom of the support shaft 27 is embedded in the bearings. The transmission gears 14 are fixedly sleeved on the outer wall of the support shaft 27 through a centrally located mounting hole, so that all five circumferential transmission gears 14 simultaneously mesh with the linkage gears 15.

[0033] A force-bearing component 12 is fixedly connected to the end of the slide rod 6 located outside the sealed chamber 5. A cam 13, which is sleeved on the outside of the support shaft 27, is fitted against the outer side of the force-bearing component 12. A drive gear 18, which meshes with the linkage gear 15, is provided on the base 1. One end of the slide rod 6 is located inside the cavity of the sealed chamber 5, and the other end of the slide rod 6 extends outward through the side wall of the sealed chamber 5 and is vertically fixed to the surface of the force-bearing component 12. The other side surface of the force-bearing component 12 is fitted against the cam 13, and the cam 13 is fixedly sleeved on the outside of the support shaft 27 through a longitudinally opened mounting hole. A motor with self-locking control is fixed on the top of the base 1 by a cover. The drive gear 18 is fixedly sleeved on the outer wall of the motor's output shaft, and the motor is electrically connected to an external power source through wires.

[0034] After the motor is connected to the power supply through the wire, the output shaft of the motor drives the drive gear 18 to rotate, which in turn drives the linkage gear 15 that meshes with the drive gear 18 to rotate. This causes the five transmission gears 14 that mesh with the linkage gear 15 in the circumferential direction to drive the support shaft 27 to rotate, which in turn drives the cam 13 to rotate. As the cam 13 rotates, it pushes the slide rod 6 to slide in the through hole through the force-bearing component 12. The six slide rods 6 in the circumferential direction converge towards the center, thereby locking the fermentation vessel in the sealed chamber 5.

[0035] It is worth noting that an elastic element 11 is provided between the force-bearing component 12 and the outer wall of the sealed chamber 5, and is sleeved on the outer wall of the slide rod 6. The elastic element 11 can be a compression spring, and its two ends are respectively fixed to the opposite surfaces of the force-bearing component 12 and the sealed chamber 5.

[0036] After the fermentation vessel is covered with a sealing cap, the output shaft of the motor, which can be adjusted to rotate in both directions, drives the drive gear 18 to rotate in the opposite direction. This causes the cam 13 to move away from the surface of the force-bearing component 12 along with the support shaft 27. At this time, the elastic force of the elastic component 11 is used to reset the slide bar 6, making the operation of removing the fermentation vessel more convenient.

[0037] In addition, a buffer block 7 is fixedly connected to the end of the slide rod 6 located inside the sealed chamber 5. The buffer block 7 is made of rubber, which protects the surface of the fermentation vessel.

[0038] In addition, ball bearings 23 are evenly arranged circumferentially between the linkage gear 15 and the support column 22. A sleeve 24 is fixedly embedded in the central mounting hole of the linkage gear 15. A sliding groove 26 is opened circumferentially on the inner wall of the sleeve 24, and movable grooves 25 are evenly opened circumferentially on the outer wall of the support column 22. Ball bearings 23 are movably embedded in the movable cavity formed by each movable groove 25 and the sliding groove 26. The stability of the linkage gear 15 during rotation is ensured by the multiple circumferential ball bearings 23.

[0039] Furthermore, the adsorption driving component includes a support cylinder 8 fixed to the top of the sealing pressure member 3, and the support cylinder 8 is fixed to the top of the suction cup 4. The support cylinder 8 is fixed to the top of the through hole where the suction cup 4 is located by a transverse frame, and the inner cavity of the support cylinder 8 is connected to the inner cavity of the suction cup 4. A piston 19 is slidably provided on the inner wall of the support cylinder 8, and a threaded rod 20 that is threadedly connected to the top of the piston 19 is fixedly connected to the support cylinder 8, and the threaded rod 20 extends out of the outside of the support cylinder 8. An exhaust hole 21 is provided on the top of the support cylinder 8.

[0040] The sealing cap of the fermentation vessel is attached to the bottom of the sealing pressure component 3. Then, the threaded rod 20 is turned so that the threaded rod 20 drives the piston 19 to rotate and move on the inner wall of the support cylinder 8, so that the air in the inner cavity of the suction cup 4 is discharged to the outside through the exhaust hole 21, and the sealing cap is adsorbed by the negative pressure in the inner cavity of the suction cup 4.

[0041] The pushing assembly includes a threaded post 16 that is threadedly connected to the top frame 2, with the bottom end of the threaded post 16 rotatably positioned on top of the sealing pressure member 3. A threaded through hole penetrating the inner cavity is longitudinally formed on the top frame 2.

[0042] The bottom end of the threaded column 16 is fixedly connected to an outer cover 9, and the top of the sealing pressure member 3 is fixedly connected to a movable member 10 embedded in the inner cavity of the outer cover 9. The movable member 10 is a spherical member, and the movable member 10 can rotate freely within the spherical cavity opened on the outer cover 9.

[0043] A guide rod 17 parallel to the threaded post 16 is fixed to the top of the sealing pressure member 3. The guide rod 17 passes through the inner cavity of the top frame 2 and extends to the outside. Tightening the threaded post 16 on the top frame 2 causes the threaded post 16 to drive the outer cover 9 to slide against the outer wall of the movable member 10. As the threaded post 16 rotates and moves, the sealing pressure member 3 moves longitudinally toward the sealing chamber 5.
