Embodiment Construction

[0011] In the tank-type anaerobic and aerobic fermentation to produce biogas and organic fertilizer, one end of the reinforced concrete structure of the fermentation tank is closed, and the other end is open, that is, the top and one end of the tank are open. Using the continuous process of anaerobic fermentation and aerobic fermentation, the upper surface of the tank and one end surface must be sealed for anaerobic fermentation and open for aerobic fermentation. The problem can be solved by adopting the present invention.

[0012] figure 1 , figure 2 It is a schematic diagram of the present invention, a U-shaped groove 1-1 is provided in the rigid container 1, and the edge of the flexible covering material 2 is put in close to the U-shaped groove 1-1, and the hose 3 is embedded in the U-shaped groove 1-1, and pressed against the U-shaped groove 1-1. Flexible cover material 2 on. Close the hose deflation valve 3-2 tightly, fill the hose 3 with a certain pressure of gas fro...

Abstract

In the invention, there is a closed U-shaped groove on the interface of a rigid container and close to the U-shaped groove is put flexible covering material. A hose filled certain pressure gases inside is built-in the flexible material. The pressure produced because of the hose channel expansion makes the flexible material and the interface of the rigid container seal. The hose can be gas-filled and air-released quickly, so as to realize the sealing and seal-removing quickly between the flexible material and the interface of the rigid container.

Description

Technical field: [0001] The invention belongs to static sealing technology. Background technique: [0002] In order to prevent the leakage of gas or other media, a seal is required at the joint between the flexible covering material and the rigid container. Generally, the rope is wound and tightened. For example, in anaerobic fermentation to produce biogas, the cylindrical tank made of reinforced concrete or steel plate and the upper air bag are usually sealed with a cable belt with a tensioning device. This sealing method has poor reliability, and frequent disassembly may easily cause damage to the flexible covering material; the sealing interface is generally circular or outer polygonal in the same plane, and is not suitable for the case where the sealing interface is an inner polygon or has a three-dimensional space shape. [0003] The purpose of the present invention is to provide a simple and reliable sealing method suitable for frequent disassembly, the sealing inter...
