[0002] With the rapid development of industrial technology, the performance requirements of pipe materials for gas conveying systems in high temperature environments are increasing. Air pipe is a pipe system used for air conveying and distribution. In pneumatic conveying devices, air pipe is the conveying channel. It utilizes the energy of air flow to convey materials (such as powder, particles, etc.) in a suspended state in the pipe. The shape, size and internal smoothness of the air pipe directly affect the efficiency and stability of material conveying. Smooth air pipe inner wall can reduce the friction between the material and the pipe wall, avoid material accumulation and blockage, and ensure smooth flow of the material in the pipe.
[0003] Most existing air pipes are flexible pipes of single structure and material, which not only have relatively low mechanical strength and poor high temperature resistance, but also cannot adjust the length of the air pipe according to needs, and can only be cut to make the air pipe more wasteful. Therefore, the present application provides a telescopic silica gel air pipe. SUMMARY

[0005] To solve the above technical problems, the utility model provides a technical scheme of a telescopic silica gel air pipe, which comprises an air pipe body, the air pipe body is composed of two layers of fiber cloth and spring reinforced steel wire, a first silica gel layer is pressed and extended on both sides of the fiber cloth on the outside, a second silica gel layer is pressed and extended on one side of the fiber cloth on the inside, and waterproof and oil-repellent paint is coated on the other side, the spring reinforced steel wire is located between the first silica gel layer and the second silica gel layer, and high temperature glass fiber wire is wound outside the silica gel layer on the surface of the fiber cloth on the outside.
[0006] Preferably, the fiber cloth and the silica gel layer are shaped by being wound obliquely.
[0007] Preferably, the spring reinforced steel wire is arranged in a spiral shape as a whole.
[0008] Preferably, the waterproof and oil-repellent paint is one of fluorocarbon paint, asphalt waterproof paint and organic silicon paint.
[0009] Preferably, the high temperature glass fiber wire is located on both sides of the spring reinforced steel wire, and the high temperature glass fiber wire is embedded in the silica gel layer.
[0010] The utility model has the advantages compared with the prior art:
[0011] 1、The wind pipe can work stably at high temperature environment by setting silica gel layer, can withstand certain degree of high temperature gas or cold and hot air transportation, suitable for various high temperature operation scene;
[0012] 2、The spring reinforced steel wire is spirally arranged in the wind pipe, so that the wind pipe can be freely bent and stretched, has strong mechanical strength, can adapt to various complex installation environment and space layout, can be easily installed and used in narrow and curved space, and is not easy to be damaged in the bending process.
