Abstract

The utility model relates to a pneumatic transport permeable belt. The utility model is characterized in that the number of the plain weave layer weaved by warp yarns and weft yarns is three to seven; the three to seven plain weave layers are knotted and weaved by hanging warp threads; the uppermost plain weave layer and the lowermost plain weave layer are all the glass fiber wire layers, and one to five plain weave layers between the uppermost plain weave layer and the lowermost plain weave layer are chemical fiber wire layers. The utility model is additionally weaved with the glass fiber wire layers on the original permeable belts which completely use the chemical fiber wire layers. The utility model overcomes the problem that under the general situation, the originally used chemical fiber materials are suitable for transporting the normal-temperature materials, and the chemical fiber yarn is easy to generate constriction or deformation to influence the permeable function when the temperature of the material is high.

Description

Pneumatic conveyer air permeable belt

Technical field

The utility model belongs to conveyer belt, especially a kind of Pneumatic conveyer air permeable belt.

Background technology

Air permeable belt has and transmits the characteristics steady, that efficient is high, cost is low as granular material and granule materials strength delivery vehicles, is widely used in the mass transport in fields such as metallurgy, building materials, electromechanics, chemical industry, boats and ships, food.Because the material that air permeable belt adopts is the filament fabric, so Pneumatic conveyer air permeable belt can only be applicable to the mass transport of normal temperature, as cement, grain, building materials material etc.; For the mass transport of high temperature, the chemical fiber fabric is met high temperature and is easy to generate the phenomenon of synerised or distortion, thereby has influenced permeability, has also just influenced mass transport.And existing high temperature resistant air permeable belt is to adopt metal material to make, and higher being difficult to of cost applies.By retrieval, also there is not resistant to elevated temperatures nonmetal Pneumatic conveyer air permeable belt at present.

Summary of the invention:

The purpose of this utility model provides a kind of simple and reasonable and resistant to elevated temperatures nonmetal Pneumatic conveyer air permeable belt.

The utility model solves its technical problem and takes following technical scheme to realize:

This Pneumatic conveyer air permeable belt, constitute the plain weave layer and tie braiding by warp thread and weft yarn by hanging through toe-in, it is characterized in that: the plain weave layer that warp thread and weft yarn braiding are constituted is 3～7 layers, these 3～7 layers of plain weave layers are by hanging through the braiding of toe-in knot, the plain weave layer of the superiors and the plain weave layer of lower floor are the glass fiber layer, and 1～5 layer of plain weave layer therebetween is for changing layer of filament.

And the warp thread of the plain weave layer of described plain weave layer that hangs the warp thread and the superiors and lower floor is the glass fiber of 1000D * 1 gang silk～1000D * 20 strands of silks, and weft yarn is the glass fiber of 1000D * 1 gang silk～1000D * 32 strands of silks.

And, can contain 0～10% chemical fibre silk in the glass fiber of described formation weft yarn.

Advantage of the present utility model and beneficial effect are:

1. braiding adds the glass fiber layer in original air permeable belt that adopts the chemical fibre silk fully, the fibers material that has overcome original employing is fit to carry the normal temperature material generally speaking, if being easy to generate, temperature of charge height, man-made fibre yarn shrink or distortion and influence the problem of airing function.

2. by plain weave layer and the whole air permeable belt that hangs the multilayer that warp constitutes, global tissue is tight, permeability is good, scientific structure, advantages of simple, can reach the purpose of carrying different high temperature granular materials, fully can the higher high-temperature metal conveyer belt of alternative cost, be the regeneration product of existing strength air permeable belt.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is further described:

Existing Pneumatic conveyer air permeable belt all is to adopt the braiding of chemical fibre silk to make, and the chemical fibre silk comprises terylene thread, nylon yarn, Fang Lunsi, polypropylene fibre silk etc.The Pneumatic conveyer air permeable belt 1 that the utility model is related also is to be constituted the plain weave layer and tied braiding by hanging warp 4 knots by warp thread 2 and weft yarn 3.Wherein, the plain weave layer that warp thread and weft yarn braiding are constituted is 3～7 layers, is 5 layers in the present embodiment, is respectively a, b, c, d, e layer, the plain weave layer e of the plain weave layer a of the superiors of these 5 layers of plain weave layers and lower floor is the glass fiber layer, and b therebetween, c, d layer plain weave layer are for changing layer of filament.

The plain weave layer of the superiors and the plain weave layer of lower floor are the resistance to elevated temperatures that the glass fiber layer can improve air permeable belt effectively.The warp thread that hangs the plain weave layer of the plain weave layer of the warp and the superiors and lower floor is the glass fiber of 1000D * 1 gang silk～1000D * 20 strands of silks, and weft yarn can adopt the glass fiber of 1000D * 1 gang silk～1000D * 32 strands of silks.

In addition, also can contain 0～10% chemical fibre silk in the glass fiber of weft yarn, this chemical fibre silk and glass fiber together weave, and also can play certain high-temperature resistant result.
