Description

Tubular conveyer belt

Technical Field

The utility model relates to a tubulose conveyer belt, especially an aramid fiber tubulose conveyer belt, but wide application in the transport of industry bulk cargo material.

Background

The conveying belt is a large composite material part consisting of a rubber covering rubber material, a framework material and an interface bonding material, is widely applied to material transportation in the fields of mining, steel smelting, building material cement, ports and docks, thermal power generation and the like, and has an important supporting effect on the development of important national economy. In traditional belt conveyor, the material is open operation, and the problem that the material scatters, dust flies, pollutes the environment or the material is polluted easily appears in the operation process. The tubular conveyer belt as one kind of environment protecting continuous conveyer apparatus has the advantages of opened and grooved conveyer belt in the material conveying area and the material unloading area, circular conveyer belt rolled with finger pressing roller, and sealed pipe maintained. Compared with the traditional open material conveying, the tubular conveying belt has the following advantages: the closed conveying can effectively prevent the materials from being scattered, avoid the pollution of the materials and protect the working environment; the bending transportation is easier to realize, and more complex workplaces are met; the large-inclination conveying can be completed; high-speed and large-capacity transportation can be realized.

Compared with the traditional groove type conveyor belt, the tubular conveyor belt has high requirements on the rubber layer and the framework layer of the conveyor belt. The transverse rigidity value is too large or too small due to improper structural design or material selection, too large causes too large pressure to the carrier roller, and causes too large running resistance or even incapability of running; the undersize results in poor pipe forming performance, pipe collapse and other problems, and influences material transportation. The fiber fabric is adopted as a framework layer in the market at present to prepare the tubular conveying belt, but the traditional fiber fabric has low strength, weak warp bearing capacity and limitation on the aspect of the tubular belt with high strength level; in addition, the fiber fabric and the rubber can have stress relaxation to a certain degree in the using process, so that the transverse rigidity of the tubular belt is obviously reduced after the tubular belt is used for a period of time, and the problems of pipe collapse and the like are caused.

The aramid fiber has the characteristics of small density, high strength, low elongation and the like, has remarkable advantages in the aspect of preparing light-weight, high-strength and energy-saving conveying belts, and has attracted more and more attention in recent years. Chinese patent CN 102658952 a discloses a tubular flame-retardant conveyer belt of aramid fabric laminated layer for coal mine, chinese patent CN 207684309U discloses a tubular conveyer belt with aramid fiber as skeleton, and the aramid fiber skeleton in the conveyer belt disclosed by the two patents adopts aramid fiber in both warp and weft directions. On one hand, the aramid fiber has high strength in structure, is not easy to deform in the stress process, and is easy to generate stress concentration to cause damage; on the other hand, in cost, the price of the aramid fiber is higher and is 5-10 times higher than that of the conventional polyester or nylon, so that the cost of the aramid fiber conveying belt is higher, and the market popularization of the product is influenced.
