Phase-change fire resistant conveyer belt

Abstract

The invention belongs to the technical field of conveyer belts, in particular to a phase transition high-temperature resistant conveyer belt. The section of the conveyer belt is characterized in that side adhesives are arranged at the two ends of a fabric core layer or a steel wire rope layer; the steel wire rope layer is formed by enwrapping coil adhesive in the space outside the steel wire rope; a non-working surface adhesive is arranged at the lower end of the side adhesive and fabric coil layer or the steel wire rope layer; and a working surface adhesive is arranged at the upper end of the side adhesive and fabric coil layer or the steel wire rope layer. The invention realizes the adjustable heat-resistance temperature of an adhesive belt, and also realizes 250 to 500 DEG C temperature resistance performance. The invention has the advantages of simple production process, simple structure, and lower cost; can be popularized to the fields of the metallurgy industry, the electrical power industry and the building materials industry, and the application range is wide.

Description

Technical field: [0001] The invention belongs to the technical field of conveyor belts, in particular to a phase-change 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 transport materials, not only the power consumption is large, the heat loss is large, and it is easy to cause personal injury, it is very difficult to operate. Inconvenient, therefore, the conveyor belt with light weight and good strength is more and more favored by the industry. However, the temperature resistance of the current conveyor belts is generally not good. The main reason is that the skeleton material cannot withstand high temperatures, and the rubber surface itself has poor temperature resistance and heat insulation performance.

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 transport materials, not only the power consumption is large, the heat loss is large, and it is easy to cause personal injury, it is very difficult to operate. Inconvenient, therefore, conveyor belts with light weight and good strength are more and more favored by the industry

However, the temperature resistance of the current conveyor belts is generally not good. The main reason is that the skeleton material cannot withstand high temperatures, and the rubber surface itself has poor temperature resistance and heat insulation performance. Cracks, because the cracks are large and form gaps, the heat of high-temperature materials is easily and quickly transferred to the skeleton layer with cores. Excessive temperature of the skeleton layer will cause its strength to 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 steel wire and a layer of ceramic fiber wire or glass fiber is wound on the outside. The belt of this belt Although the body frame has high strength and certain high temperature resistance, it is complicated to manufacture, and the cost of manufacturing and use is quite high, and special equipment is required to process the body frame

In addition, due to the harsh environment during 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

Patent No. 200810069236.5 Chinese patent discloses a tear-resistant and high-temperature-resistant conveyor belt, which includes a skeleton layer, a working surface cover rubber layer, a non-working surface cover rubber layer, and a transverse reinforcement layer and a buffer rubber layer. Anti-tear and high temperature performance, but the production process is still relatively complicated
