Abstract
The utility model discloses a papermaking belt negative-pressure efficient abrasion-resistant dehydrating device which comprises a groove body (1). A negative-pressure pipe (2) and a water discharging pipe (5) are arranged at two ends of the groove body (1). Negative-pressure supporting plates (4) are arranged on the groove body (1), the negative-pressure supporting plates (4) are abrasion-resistant supporting plates, negative-pressure gaps are formed among the plates, and blocking plates (3) are arranged at two ends of the negative-pressure gaps. An abrasion-resistant strip plate is used as a negative-pressure carrying plate of the negative-pressure groove body so that a negative-pressure dehydrating groove is durable. The problem that dehydrating efficiency is reduced and a papermaking dehydrating effect is affected due to air leakage caused by supporting plate abrasion is solved. The papermaking belt negative-pressure efficient abrasion-resistant dehydrating device is simple in structure, durable and abrasion-resistant and good in sealing effect and improves paper product quality.
Description
Technical field
The utility model belongs to the paper making equipment technical field, is specifically related to a kind of simple in structurely, is easy to implement, and stable and reliable operation is copied paper tape negative pressure high-efficiency abrasion-proof dewater unit.
Background technology
Papermaking technology is one of four inventions of China, and along with development of technology, papermaking has become automatic production line production by the production of handicraft workshop formula, has improved production efficiency greatly.Prior art is all finished by belt conveyor automatically continuously from copying the paper operation to the paper tape drying.In order to improve the quality of paper, reduce the dehydration intensity of drying process, cut down the consumption of energy, improve the compactedness of paper simultaneously, the starting stage after copying paper is carried out roll extrusion and dehydration.Prior art papermaking dehydration has multiple mode, and its main mode has roll extrusion, negative pressure, oven dry etc., and wherein the negative pressure dehydration is easy to implement with its efficient height, has become to copy the indispensable link of paper drying process.The negative pressure dehydration of prior art is to adopt the slot type structure, and smooth surface supporting plate and negative pressure crack are set on the notch, because the specific (special) requirements of negative-pressure sealing usually because the supporting plate wearing and tearing cause the negative pressure deficiency, influences dehydrating effect.For this reason, develop a kind of simple in structure, durable wear, good sealing effect to copy paper tape negative pressure high-efficiency abrasion-proof dewater unit be the key that overcomes the prior art deficiency, help to improve paper quality.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, durable wear, good sealing effect copy paper tape negative pressure high-efficiency abrasion-proof dewater unit.
The purpose of this utility model is achieved in that and comprises cell body that described cell body two ends arrange negative pressure pipe and drainpipe, the negative pressure supporting plate is set on the described cell body, described negative pressure supporting plate is wear-resisting supporting plate, constitutes the negative pressure crack between plate, and two ends, described negative pressure crack arrange the shutoff plate.
The utility model takes wear-resisting batten as the negative pressure bearing plate of negative pressure cell body, makes that the negative pressure drench pit is durable in use, prevents from leaking gas because of the supporting plate abrasion, causes dewatering efficiency to descend, and the paper dehydrating effect is copied in influence.The utility model is simple in structure, durable wear, sealing effectiveness, the quality of raising paper products.

Among the figure: 1-cell body, 2-negative pressure pipe, 3-shutoff plate, 4-negative pressure supporting plate, 5-drainpipe, the moisture paper tape of 6-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in drawings, the utility model comprises cell body 1, and described cell body 1 two ends arrange negative pressure pipe 2 and drainpipe 5, on the described cell body 1 negative pressure supporting plate 4 is set, described negative pressure supporting plate 4 is wear-resisting supporting plate, constitutes the negative pressure crack between plate, and two ends, described negative pressure crack arrange shutoff plate 3.
Described negative pressure supporting plate 4 is corrosion-resistant bright and clean lath.
Described negative pressure supporting plate 4 two ends and shutoff plate 3 are sealed and matched.
Described negative pressure supporting plate 4 is whole bright and clean smooth consistent with shutoff plate 3 surfaces.
Described negative pressure supporting plate 4 is ceramic wafer and whole bright and clean smooth consistent with shutoff plate uniform thickness and surface.
The bright and clean slyness of the side of the ceramic wafer of described negative pressure supporting plate 4.
Described negative pressure supporting plate 4 is distributed on the notch and is suitable with the width of shutoff plate.
Described negative pressure supporting plate 4 be nylon sheet or polyethylene board and with shutoff plate uniform thickness.
The utility model operation principle and the course of work:
The utility model takes wear-resisting batten as the negative pressure bearing plate of negative pressure cell body, makes that the negative pressure drench pit is durable in use, prevents from leaking gas because of the supporting plate abrasion, causes dewatering efficiency to descend, and the paper dehydrating effect is copied in influence.
During work, the utility model placed copy under the paper tape, with copy the paper tape tensioned fit, the negative pressure pipe is inserted vacuum system, start vavuum pump, open drainpipe and control drainage speed, keep cell body that the water yield that can seal water discharge outlet is arranged, the moisture of copying in the paper tape flows in the groove under suction function, and discharges slowly from drainpipe.According to the gait of march of copying paper tape, control negative pressure intensity reaches best dehydrating effect, to improve the quality of paper products.
