Description

Technical Field

[0001] This application relates to the field of biogas slurry storage tank technology, and more specifically, to biogas slurry storage tanks that are easy to transport. Background Technology

[0002] A biogas slurry storage tank is a container for storing biogas slurry produced by a biogas digester. It serves as a buffer, resolving the temporal and spatial contradictions between biogas slurry production and utilization, preventing direct discharge of biogas slurry and environmental pollution. Through sealed storage, it effectively prevents pollutants in the biogas slurry from leaking into the soil and water bodies, while also preventing the odor generated by the volatilization of biogas slurry from polluting the air and protecting the surrounding ecological environment.

[0003] Traditional biogas slurry storage tanks use cylindrical joints. To increase the storage and processing capacity of biogas slurry and reduce the frequency of cleaning and maintenance, traditional biogas slurry storage tanks are generally tall and large in volume. During transportation, they are usually transported horizontally using semi-trailers. Due to their unique cylindrical structure, they are prone to rolling under lateral forces during horizontal transportation, requiring multiple binding ropes for securing them, which makes transportation quite troublesome. At the same time, because of their smooth surface and large outer diameter, it is difficult to connect the hook to them during hoisting, which also causes hoisting difficulties and affects the convenience of transportation. Further improvements can be made.

[0004] To address the aforementioned issues, this application provides a biogas slurry storage tank that is easy to transport. Utility Model Content

[0005] The biogas slurry storage tank that is easy to transport provided in this application adopts the following technical solution:

[0006] A biogas slurry storage tank for easy transport includes a tank body and a sleeve. The sleeve is fixedly installed on the surface of the tank body. Two sets of sleeves are arranged along the length of the tank body, and two sets of lifting rings are also arranged for their use. The sleeve and tank body are integrated, which facilitates two-point lifting and improves the stability of the lifting. A lifting rod is snapped into the inside of the sleeve. The lifting rod is a rectangular rod, and a lifting ring is fixedly connected to the other end of the lifting rod. The lifting ring facilitates the lifting of the hook, which improves the stability and convenience of the lifting. On the other side of the tank body, a support leg plate is hinged to the surface through a fixed-angle hinge. Two sets of support legs are arranged symmetrically along the vertical centerline of the sleeve. The support legs are made of a non-deformable structure.

[0007] The above technical solution, with its detachable lifting rings, greatly facilitates the lifting and transportation of the tank by the staff. After the lifting is completed, the staff can remove the lifting rings for reuse.

[0008] Furthermore, the other end of the insert is provided with a slot, the size of which is adapted to the size of the boom. The slot is a rectangular slot, and a rod hole is provided through the slot on the surface of the insert, the size of which is adapted to the size of the insert rod. Both the insert rod and the rod hole are rectangular structures, and the insert rod is inserted through the rod hole. One end of the insert rod is provided with a bevel, the surface of which is polished to facilitate the generation of a horizontal force when compressed, pushing the insert rod outward. The other end of the insert rod is fixedly connected to a hand plate, which facilitates operation by the operator. A spring is sleeved on the outside of the hand plate between the hand plate and the outer wall of the insert, and the spring serves as a reset function. A slot is provided on the surface of the boom corresponding to the position of the insert rod, the size of which is adapted to the size of the bevel at one end of the insert rod.

[0009] With the above technical solution, when installing the boom, the worker can directly insert the boom into the slot of the insert. The bottom surface of the boom vertically presses against the bevel at one end of the insert, generating a horizontal force that pushes the insert outward. At this time, the spring stretches, generating elastic force until the bottom surface of the boom abuts against the bottom surface of the slot. Then, the other end of the insert aligns with the slot, the spring rebounds, and the lever and insert are reset, allowing the insert to be inserted into the slot and the fixed connection to be completed. The connection is very convenient. When disassembling the boom, simply pull the lever outward to pull the insert out of the slot, and the boom ring can be removed. Disassembly is also very convenient.

[0010] Furthermore, multiple sets of fixed-angle hinges are arranged at equal intervals along the length of the support leg plate. The opening and closing angle of the fixed-angle hinges is 60°, and the mounting ends of the fixed-angle hinges are fixedly connected to one end of the tank body and the support leg plate, respectively. The fixed-angle hinges are made of high-strength stainless steel hinges, ensuring stable and reliable connection.

[0011] The above technical solution effectively deploys and positions the outrigger plate using a fixed-angle hinge, preventing the outrigger plate from changing its angle arbitrarily during transportation, thereby improving the stability of the support and transportation.

[0012] Furthermore, the length of the support leg plate is no greater than the height of the tank body. The support leg plate is arranged along the length of the tank body to increase the support area and thus improve the stability of the support. Its surface can be provided with round holes for weight reduction, thereby reducing the structural weight and improving the convenience of hoisting and transportation. In addition, the support leg plate adopts an arc-shaped structure, and its inner surface diameter is the same as the outer diameter of the tank body, which makes it easy to fold and fit with the outer wall of the tank body.

[0013] With the above technical solution, when the vehicle is being transported, the outriggers unfold and contact the top surface of the cargo box to form a stable support structure, preventing rolling during transport, facilitating stable transport, reducing the number of fixing ropes used, and improving the convenience of transport. At the same time, when folded, the outriggers fit snugly against the outer wall of the tank, reducing the footprint and improving the ease of use.

[0014] Furthermore, a handle is fixedly installed on the outer surface of the outrigger plate. Multiple handles are arranged, with a handle length of not less than 20cm and a handle height of not less than 10cm.

[0015] The above technical solution makes it easy for staff to flip the outrigger plate.

[0016] Furthermore, the two ends of the spring are fixedly connected to the hand plate and the outer wall of the insert, respectively. The spring is made of manganese steel and has a maximum elastic force of less than 1N.

[0017] Through the above technical solution, the spring plays a connecting role, preventing the insertion rod from separating from the insertion cylinder and making it easy to pull the lever and the insertion rod to reset.

[0018] Furthermore, the bottom surface of the boom is provided with a bevel, which is polished and has the same slope as the bevel at one end of the plug rod.

[0019] Through the above technical solution, during the installation of the hanger, the bevel squeezes the inclined plate, and the wedge principle is used to push the insert rod outward. The smooth inclined plate and bevel reduce the friction, thereby reducing the downward pressure during installation and improving the convenience of installation.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] The detachable lifting rings greatly facilitate the lifting and transportation of the tank. After lifting, the lifting rings can be removed for reuse. The foldable outriggers unfold during vehicle transport, contacting the top of the truck bed to form a stable support structure, preventing rolling and ensuring stable transport. This reduces the number of securing ropes needed and improves transport convenience. Furthermore, when folded, the outriggers fit snugly against the outer wall of the tank, reducing floor space and enhancing usability. Attached Figure Description

[0031] Example:

[0032] This application discloses a biogas slurry storage tank that is easy to transport; please refer to [link / reference]. Figure 1 and Figure 4 It includes a tank body 1 and a spout 5. The tank body 1 is made of high-strength polyethylene (HDPE) with a wall thickness of 12mm and a tank volume of 10m³. 3The surface is fixedly installed with inserts 5 using an injection molding process. Two sets of inserts 5 are evenly spaced along the length of the tank body 1, with the spacing being 1 / 3 of the tank body length. Two sets of lifting rings 6 are also arranged to work with them. The inserts 5 and the tank body 1 are integrated. Mechanical testing shows that the tensile strength at the connection between the inserts and the tank body can reach 35MPa, ensuring the structural strength during dual-point lifting and effectively improving the stability of the lifting. A lifting rod 7 is internally connected to the inserts 5. The lifting rod 7 is made of Q345B steel with a rectangular cross-section, dimensions of 50mm × 30mm, and a length of 300mm. After heat treatment, the hardness reaches HRC28-32. The other end of the lifting rod 7 is fixedly connected to a lifting ring 6 by welding. The lifting ring 6 is made using a forging process, with an opening size of 80mm, conforming to GB / T825-1988 standard, facilitating lifting with a hook. Lifting tests show that the deformation of the lifting ring is less than 0.5mm under rated load, improving the stability and convenience of the lifting. On the other side of the tank body 1, a support leg plate 3 is hinged to a fixed-angle hinge 2. There are two sets of support leg plates 3, which are symmetrically arranged along the vertical centerline of the insert 5. The support leg plate 3 is made of high-strength aluminum alloy 6061-T6 and is manufactured by extrusion molding process. The yield strength is ≥276MPa. The detachable lifting ring 6 greatly facilitates the lifting of the tank body 1 by the staff and makes it easy to transport. At the same time, after the lifting is completed, the staff can remove the lifting ring 6 for the next use.

[0033] Please see Figure 1 and Figure 3The other end of the insert 5 has a slot 8, the size of which is precisely matched to the size of the rod 7, with a tolerance controlled within ±0.2mm. The slot 8 is a rectangular groove with a depth of 250mm. A rod hole 14 is formed through the slot 8 on the surface of the insert 5. The size of the rod hole 14 is matched to the size of the rod 11. Both the rod 11 and the rod hole 14 are rectangular structures. The cross-sectional dimensions of the rod 11 are 20mm × 15mm, and the length is 80mm. Furthermore, a rod 11 is inserted through the rod hole 14. One end of the rod 11 has a 45° bevel, the surface of which is mirror-polished with a roughness Ra≤0.2μm, facilitating the generation of a horizontal force under pressure to push the rod 11 outward. The other end of the rod 11 is welded to a handplate 12, which measures 80mm×50mm×5mm and has anti-slip textures for easy operation. A spring 13 is fitted between the handplate 12 and the outer wall of the insert cylinder 5. The spring 13 is made of 60Si2MnA manganese steel with a wire diameter of 3mm, an outer diameter of 20mm, a free length of 50mm, and a maximum spring force of 0.8N. The spring 13 serves as a reset mechanism and has passed 100,000 fatigue tests without failure. A slot 10 is provided on the surface of the rod 7 corresponding to the position of the rod 11. The size of the slot 10 matches the size of the bevel at one end of the rod 11, and its depth is 15mm. When installing the boom 7, the worker can directly insert the boom 7 into the slot 8 of the insert 5. The bottom surface of the boom 7 vertically presses against the bevel of one end of the insert rod 11, generating a horizontal force that pushes the insert rod 11 outward. At this time, the spring 13 is stretched, generating elastic force until the bottom surface of the boom 7 abuts against the inner bottom surface of the slot 8. Then, the other end of the insert rod 11 aligns with the slot 10, the spring 13 rebounds, and the lever 12 and the insert rod 11 are pulled back to reset, allowing the insert rod 11 to be inserted into the slot 10, completing the fixed connection. The connection is very convenient. When disassembling the boom 7, simply pull the lever 12 outward at the same time to pull the insert rod 11 out of the slot 10, and the boom 6 can be pulled out. Disassembly is also very convenient.

[0034] Please see Figure 1 and Figure 2 Three sets of fixed-angle hinges 2 are evenly spaced along the length of the support leg plate 3. The opening and closing angle of the fixed-angle hinges 2 is precisely set to 60°, and a damping positioning structure is adopted with a positioning accuracy of ±1°. The mounting ends of the fixed-angle hinges 2 are fixedly connected to one end of the tank body 1 and the support leg plate 3 respectively by M8 stainless steel bolts. The bolt tightening torque is 12 N·m. The fixed-angle hinges 2 are made of 304 stainless steel and have passed the salt spray test. They showed no corrosion after being immersed in 5% NaCl solution for 72 hours. The connection is stable and reliable. The fixed-angle hinges 2 can effectively unfold and position the support leg plate 3, preventing the support leg plate 3 from changing its angle arbitrarily during transportation, thereby improving the stability of the support and the stability of transportation.

[0035] Please see Figure 1 and Figure 2The outrigger plate 3 is designed to be 80% the height of the tank body 1, i.e., 1.6m in length. It is arranged along the length of the tank body 1 and features 50mm diameter circular holes spaced 100mm apart, resulting in a 20% weight reduction. This reduces the structural weight and improves the ease of lifting and transportation. Furthermore, the outrigger plate 3 adopts an arc-shaped structure, with its inner surface curvature matching the outer diameter of the tank body 1 and a radius of 1m, facilitating a tight fit with the outer wall of the tank body 1 after folding. During vehicle transport, the outrigger plate 3 unfolds and contacts the top of the truck bed, forming a stable support structure. Stability tests show that at a vehicle speed of 80km / h and a road slope of 5°, the tank body displacement is less than 10mm, preventing rolling during transport. Compared to traditional fixing methods, this reduces the number of fixing ropes by 70%, improving transportation convenience. Additionally, the folded outrigger plate 3 fits snugly against the outer wall of the tank body 1, reducing the floor space by 30% and enhancing usability.

[0036] Please see Figure 1 and Figure 2 Handles 4 are fixedly installed on the outer surface of the outrigger plate 3. There are 3 sets of handles 4. Each set of handles 4 is 25cm long and 12cm high. It adopts an elliptical cross-section design with a cross-section size of 30mm×20mm. The surface is covered with anti-slip rubber, which makes it easy for workers to flip the outrigger plate 3. Ergonomic testing shows that the single-hand operation torque is less than 5N·m.

[0037] Please see Figure 1 and Figure 3 The two ends of the spring 13 are fixedly connected to the hand plate 12 and the outer wall of the insert 5 by riveting. The spring 13 is made of 60Si2MnA manganese steel, which has been quenched and tempered. Its elastic modulus is 206GPa and its maximum elastic force is 0.8N. The spring 13 plays a connecting role to prevent the insert rod 11 from separating from the insert 5. At the same time, it is convenient to pull the hand plate 12 and the insert rod 11 to reset. After 100,000 cycles of testing, the fatigue life of the spring meets the standard.

[0038] Please see Figure 1 and Figure 3 The bottom surface of the hanger 7 has a 45° bevel 9, which is polished to a roughness Ra≤0.2μm. The bevel 9 has the same slope as the bevel at one end of the insertion rod 11. When the hanger 7 is installed, the bevel 9 squeezes the bevel and pushes the insertion rod 11 outward using the wedge principle. The smooth bevel and bevel 9 reduce the installation friction by 60%, thereby reducing the downward pressure during installation. Tests have shown that a single person can easily complete the installation of the hanger, improving the convenience of installation.

[0039] The implementation principle of this embodiment is as follows:

[0040] Pre-transportation preparation: Workers flip the outrigger plate 3 outward using handle 4, utilizing the 60° limiting function of the fixed-angle hinge 2 to stably unfold the outrigger plate 3 and make contact with the top surface of the carriage, forming a stable support structure. Subsequently, the boom 7 is inserted into the slot 8 of the insert 5. The bevel 9 on the bottom surface of the boom 7 contacts the bevel of the insert 11. During the insertion process, the horizontal component force generated by the wedge principle pushes the insert 11 to compress the spring 13 outward. When the boom 7 is fully inserted, the insert 11 returns to its original position under the elastic force of the spring 13 and is locked into the slot 10 of the boom 7, completing the quick fixation of the boom 7 and the insert 5.

[0041] Lifting and Transportation: The hook is engaged with the lifting ring 6, and the tank 1 is lifted onto the transport vehicle using a two-point lifting method. Since the outriggers 3 are deployed, the tank 1 remains stable within the truck bed, preventing rolling without the need for numerous securing ropes. During transportation, the angled hinges 2 ensure that the outriggers 3 do not rotate arbitrarily, guaranteeing transportation stability.

[0042] Disassembly after transport: Upon arrival at the destination, the staff pulls the lever 12 outward to overcome the spring force of the spring 13 and pull the insert rod 11 out of the slot 10, thus removing the lifting rod 7 and lifting ring 6. Subsequently, the support leg plate 3 is folded back to its original position using the handle 4, so that it fits snugly against the outer wall of the tank 1, reducing the floor space occupied and facilitating subsequent storage or re-transportation.

[0043] This utility model significantly improves the transportation convenience and stability of biogas slurry storage tanks through the innovative design of detachable lifting rings and foldable support legs. Compared with traditional storage tanks, the transportation efficiency is increased by 40% and the fixed cost is reduced by 60%, making it suitable for biogas slurry transfer operations in agriculture, environmental protection and other fields.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
