The coating can drop under the effect of ambient pressure. The utility model discloses a coating coarse cotton cloth is equipped with the coating, can make coarse cotton cloth in that to operate the computer the initial stage air permeability lower, makes coarse cotton cloth reduce the phase of taming, the later stage in -process, the coating drops, makes the air permeability of coarse cotton cloth maintain a stable level.

Description

A kind of coating felt

Technical field

This utility model relates to pulp technology for making paper, is specifically related to a kind of coating felt.

Background technology

The profit of paper-making industry constantly reduces, and improving paper machine speed becomes raising production efficiency, reduces life Produce an important step of cost.And felt machine initial stage on firm, the mesh of base net is in open shape State, the more stiff straight elevator of fibre fluff, on performance felt, machine state is that air permeability is higher, vacuum Low, dehydrating amount is less.There is the problem taming phase length in the felt of upper machine, thus for a long time can not Reach design speed, the performance of limit paper machine production capacity.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of coating felt, existing to solve The problem that in technology, phase length tamed by felt.

The coating felt that this utility model provides includes:

Base net, described base net has three layers, has for ventilative mesh between described base net, described Base net has supporting role；

Coating, described coating is wrapped in described base net surface, covers the part mesh of described base net； And

Fibre fluff, described fibre fluff is implanted in described base net, fills up the mesh of described base net.

Preferably, described coating can come off under the effect of ambient pressure.

The coating felt that this utility model provides is in one layer of coating of described base net surface smear, thus subtracts The mesh of few felt, the implantation of the most described fibre fluff, make the mesh portion of described base net by institute State fibre fluff to fill up, reduce the effect of air permeability, reduce the taming phase of felt, make simultaneously Felt is more solid.It addition, described coating can come off under the effect of ambient pressure.Running During, under the effect of water under high pressure, described coating gradually comes off, until completely falling off.Institute State coming off of coating and expose the part mesh of described base net 1.Two felt can be subject in running To extruding and the pollution of foul, felt is made gradually to close.Coming off of described coating compensate for felt Gradually close, make the permeability of felt maintain a preferable state.

Accompanying drawing explanation

By description to this utility model embodiment referring to the drawings, of the present utility model above-mentioned And other objects, features and advantages will be apparent from, in the accompanying drawings:

Fig. 1 illustrates structural representation of the present utility model.

Detailed description of the invention

It is more fully described various embodiment of the present utility model hereinafter with reference to accompanying drawing.Attached at each In figure, identical element uses same or similar reference to represent.For the sake of clarity, Various piece in accompanying drawing is not necessarily to scale.

As it is shown in figure 1, coating felt of the present utility model includes: base net 1, be wrapped in described base The coating 2 on net 1 surface and implant the fibre fluff 3 of described base net 1.

Specifically, described base net 1 has three layers, has for ventilative mesh between described base net 1, Described base net 1 has supporting role, is provided that again ventilative mesh.

Described coating 2 is wrapped in described base net 1 surface, covers the part mesh of described base net 1, Felt is made to close in the comparison that the upper machine initial stage shows.

Described fibre fluff 3 maos is implanted in described base net 1, fills up the mesh of described base net 1. Described fibre fluff 3 has protective effect to described base net 1, can reduce dirty, make felt simultaneously Air permeability reach requirement level.It addition, described base net 1 is more tied by described fibre fluff 3 Link together on the spot.

Coating felt of the present utility model is in described one layer of coating 2 of base net 1 surface smear, thus subtracts The mesh of few felt, the implantation of the most described fibre fluff 3, make the mesh portion of described base net 1 Filled up by described fibre fluff 3, reduce the effect of air permeability, make felt more solid simultaneously.

It addition, described coating 2 can come off under the effect of ambient pressure.During running, Under the effect of water under high pressure, described coating 2 gradually comes off, until completely falling off.Described coating 2 Come off and expose the part mesh of described base net 1.Two felt can be squeezed in running With the pollution of foul, felt is made gradually to close.Coming off of described coating 2 compensate for felt gradually Close, make the permeability of felt maintain a preferable state.

It should be noted that, in this article, the relational terms of such as first and second or the like is only It is used for separating an entity or operation with another entity or operating space, and not necessarily requires Or imply relation or the order that there is any this reality between these entities or operation.And, Term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, So that include that the process of a series of key element, method, article or equipment not only include that those are wanted Element, but also include other key elements being not expressly set out, or also include for this process, The key element that method, article or equipment are intrinsic.In the case of there is no more restriction, by statement " include one ..., " key element that limits, it is not excluded that include the process of described key element, method, Article or equipment there is also other identical element.

Last it is noted that obvious, above-described embodiment is only new for clearly demonstrating this practicality Type example, and not restriction to embodiment.Ordinary skill people for art For Yuan, can also make other changes in different forms on the basis of the above description. Here without also cannot all of embodiment be given exhaustive.And thus amplified out aobvious and easy The change seen or variation still in protection domain of the present utility model among.
