Description

Technical Field

[0001] This utility model relates to the field of double-membrane gas storage tank technology, and in particular to an explosion-proof biogas double-membrane gas storage tank that is easy to maintain. Background Technology

[0002] Double-membrane gas holders are devices used to store neutral gases such as biogas. The double-membrane gas holder is 3 / 4 spherical in shape and is fixed to a cement base or the top of an anaerobic tank by steel rails. The main body is made of specially processed polyester material (the main components are red mud soft composite membrane and red mud soft mesh cloth). The tank consists of an outer membrane, an inner membrane, a bottom membrane (above-ground tank) and auxiliary equipment. It has the ability to resist ultraviolet rays and various microorganisms, is highly fireproof and meets the standards.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing double-membrane gas storage tanks are all fixed to the cement base by steel rails, and most of the steel rails are integral structures, which are inconvenient to disassemble, thus making it inconvenient to maintain the double-membrane gas storage tank. In addition, the gas connection pipes of the outer membrane are mostly fixed directly by bolts, which are inconvenient to install and disassemble, thus making it inconvenient to maintain the whole and reducing the overall practicality. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof biogas double-membrane gas storage tank that is easy to install and disassemble and maintain.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An explosion-proof biogas double-membrane gas storage tank that is easy to maintain includes a base membrane laid on the ground, an inner membrane laid on top of the base membrane, and an outer membrane of the gas storage tank laid outside the inner membrane. A clamping plate structure for pressing the base membrane, inner membrane, and outer membrane of the gas storage tank is detachably connected to the outer membrane of the gas storage tank. An exhaust pipe for venting the outer membrane of the gas storage tank is fixedly connected to the outer membrane of the gas storage tank. A ventilation device for venting the outer membrane is detachably connected to the end of the exhaust pipe away from the outer membrane of the gas storage tank. A pipe clamp is fixedly connected to the end of the exhaust pipe near the ventilation device. A pipe plug fitting adapted to the pipe clamp is fixedly connected to the side of the ventilation device near the exhaust pipe.

[0007] By adopting the above technical solutions, the pipe clamps and pipe plugs are easy to install and disassemble, which facilitates the replacement of the ventilation equipment and the cleaning of the pipes, ensuring normal overall use. At the same time, the outer membrane of the gas storage tank is fixed by the split-type pressure plate structure, which facilitates the full compression of the outer membrane of the gas storage tank and reduces the overall maintenance workload.

[0008] Furthermore, the clamping plate structure is a split structure, and the clamping plate structure includes annularly spaced arc-shaped card seats inside. One side of the arc-shaped card seat is provided with a fixing slot, and the other side of the arc-shaped card seat is fixedly connected with a fixing block that matches the fixing slot.

[0009] By adopting the above technical solution, the split-structure arc-shaped bracket is easy to splice and fix, and the whole is easy to install and disassemble, which increases the overall fixing speed and disassembly speed, and increases the overall flexibility.

[0010] Furthermore, the fixed insert has a positioning screw hole inside, and the arc-shaped card seat has a positioning screw threaded inside, which passes through the arc-shaped card seat and is threadedly connected to the positioning screw hole.

[0011] By adopting the above technical solution, the positioning screw passes through the arc-shaped bracket and is threadedly connected to the positioning screw hole, which can fully press and position the arc-shaped bracket of the split structure, making it convenient for the whole to be stably installed and fixed, and convenient for the whole to be installed and dismantled, thus increasing the overall practicality.

[0012] Furthermore, the arc-shaped bracket is internally fixedly connected with a pressure strip for pressing the edges of the bottom membrane, inner membrane, and outer membrane of the gas storage tank. The upper end face of the arc-shaped bracket is threaded with a mounting screw, which passes through the upper end face of the arc-shaped bracket, the bottom membrane, the inner membrane, and the outer membrane of the gas storage tank and is fixed to the ground.

[0013] By adopting the above technical solution, the pressure strip can fully compress the bottom membrane, inner membrane, and outer membrane of the gas storage tank, preventing the openings of the bottom membrane, inner membrane, and outer membrane of the gas storage tank from not being fully sealed, thus increasing the overall sealing effect.

[0014] Furthermore, the pipe clamp includes a mating inner tube, and a clamping outer tube is fixedly connected to the outside of the mating inner tube. A insertion groove is reserved between the clamping outer tube and the inside of the mating inner tube, and a positioning locking hole is opened on the side wall of the clamping outer tube, which communicates with the inside of the insertion groove.

[0015] By adopting the above technical solution, the snap-fit ​​outer tube and the connecting inner tube can be easily installed and disassembled, and the snap-fit ​​outer tube and the connecting inner tube are fixed and disassembled by snap-fit, ensuring good overall flexibility.

[0016] Furthermore, the pipe connector includes a connector fixed to the air inlet of the ventilation equipment. The inner wall of the connector is movably connected to a positioning button that matches the positioning hole. The connector has a movable groove for the positioning button to move inside. A mounting spring is fixedly connected inside the movable groove. The side of the mounting spring away from the movable groove is fixedly connected to the positioning button.

[0017] By adopting the above technical solution, the spring drives the positioning button to engage with the positioning hole, thereby facilitating the stable fixing of the outer tube and the inner tube, and ensuring a good fixing effect between the outer tube and the inner tube.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. The outer membrane of the gas storage tank is fixed by a split-type fixing seat, which makes it easy to install and fix the outer membrane of the gas storage tank. When disassembling, it is not necessary to remove the whole thing together, which reduces the amount of work required for overall disassembly and produces the effect of easy overall assembly and disassembly.

[0020] 2. A spring is used to engage the positioning button with the positioning hole, which facilitates stable fixing of the outer pipe and the inner pipe, ensuring a good fixing effect and making the pipe easy to install and remove.

[0021] 3. The positioning blocks and positioning slots are used to fully press and seal the bottom edge of the outer membrane of the gas tank, preventing air leakage that could lead to an imbalance in the internal pressure. This reduces the risk of an explosion due to pressure imbalance, increases overall safety, and provides an explosion-proof effect. Attached Figure Description

After the base membrane 1 is fixed, the inner membrane 2 is laid on top. Then, the outer membrane 3 of the gas storage tank is placed on top of the inner membrane 2. At the same time, the arc-shaped brackets 41 are spliced ​​to form a pressing plate structure 4, ensuring that the pressure strip 46 at one end of the arc-shaped bracket 41 presses the outer membrane 3 of the gas storage tank. Simultaneously, the pressure strip 46 presses the edges of the base membrane 1, the inner membrane 2, and the outer membrane 3 of the gas storage tank into the fixing slot 42 to form a sealed pressing structure. At the same time, the positioning screws 45 pass through the outer side of the arc-shaped bracket 41 and are threaded to the positioning screw holes 44 to ensure that each arc-shaped bracket is properly sealed. The mounting bracket 41 provides a stable installation effect, and the clamping plate structure 4, bottom membrane 1, inner membrane 2 and outer membrane 3 of the gas storage tank are fixed by the mounting screws 47 and sealed with sealant, which increases the overall installation stability. During the overall installation process, the pipe connector 8 is inserted through the insertion groove 73 between the inner pipe 71 and the outer pipe 72, and the mounting spring 84 drives the positioning button 82 to engage with the positioning hole 74, ensuring quick installation and disassembly of the pipe connector 7 and the pipe connector 8, facilitating overall maintenance and increasing overall practicality.
