Tearing-proof high temperature resisting conveyer belt

Abstract

The invention discloses an anti-tear and high temperature resistant conveyor belt, including a skeleton layer, a working face glue-covering layer, a non-working face glue-covering layer, a transverse reinforcement layer and a buffer glue layer. The transverse reinforcement layer is arranged between the skeleton layer and the buffer glue layer and is adjacent to the skeleton layer. The buffer glue layer is arranged between the transverse reinforcement layer and the working face glue-covering layer and is adjacent to the working face glue-covering layer. The skeleton layer adopts low hear shrinkage polyester canvas and the transverse reinforcement adopts polyester curtain net or metal wire. The material of the working face glue-covering layer is made by mixing ethylene propylene diene monomer with other filers with proper proportion. The material of the buffer glue layer is made by mixing the blend glue of ethylene-propylene-diene rubber and natural glue with other fillers of proper proportion. The invention improves the anti-tear and high temperature resistant performances and is widely applied to convey high temperature materials in such industrial enterprises as steelmaking plants, thermal power plants, cement plants, etc.

Description

technical field [0001] The invention relates to the technical field of conveying engineering, in particular to a tear-resistant and high-temperature-resistant conveyor belt. Background technique [0002] Because in steel mills, thermal power plants, cement plants and other factories and mines, the materials transported by the conveying machinery are all high-temperature materials. If metal crawlers are used to carry materials, not only the power consumption is large, the heat transfer is large, and it is easy to cause personal injury, it is very difficult to operate. Convenience, therefore, the conveyor belt with light weight and good strength (conveyor belt with rubber material on the belt surface) is more and more favored by the industry. However, the temperature resistance of the current conveyor belt is generally poor.

AI Technical Summary

Problems solved by technology

[0002] Because in steel mills, thermal power plants, cement plants and other factories and mines, the materials transported by the conveying machinery are all high-temperature materials. If metal crawlers are used to carry materials, not only the power consumption is large, the heat transfer is large, and it is easy to cause personal injury, it is very difficult to operate. Convenience, therefore, the conveyor belt with light weight and good strength (conveyor belt with rubber material on the belt surface) is more and more favored by the industry

However, the temperature resistance of the current conveyor belt is generally poor. The main reason is that the skeleton material cannot withstand high temperature and the rubber surface itself has poor heat resistance and heat insulation performance. Under high temperature environment, the rubber surface of the conveyor belt forms cracks due to carbonization and sintering. , due to the large gaps formed by the cracks, the heat of the high-temperature material is easily transferred to the skeleton layer with the core quickly. If the temperature of the skeleton layer is too high, its strength will decrease, thereby reducing the life of the conveyor belt.

The Chinese patent No. 02261969.0 discloses a conveyor belt, which adds a layer of heat insulation such as asbestos between the covering glue and the skeleton to prevent high temperature transmission to the canvas skeleton, but its temperature resistance is only 200 degrees Celsius It still cannot meet the industry's requirements for high temperature resistance of conveyor belts

The patent number is 200510005288.2. The Chinese patent also announced a high-temperature-resistant belt for belt conveyors. The belt frame of this belt is made of stainless steel fiber wire and a layer of ceramic fiber wire or glass fiber is wound on the outside, and several strands are used as warps. The weft thread is a ceramic canvas made of stainless steel fiber threads and warp threads interlaced at intervals of several pitches. Although the belt body skeleton of this type of belt has high strength and certain high temperature resistance, it is complicated to manufacture and expensive to manufacture and use. Quite high, requiring special equipment to process the belt frame

In addition, during use, due to the harsh environment of use, when the temperature-resistant and wear-resistant rubber conveyor belt is not strong enough, it is easy to tear, which will increase the cost of use due to repair or replacement, and will also cause loss of working hours.
