Abstract

The utility model relates to a multiporous dewatering roller with end face vacuum pumping, which is a dewatering device for fiber serial production lines of industries such as textile industry, papermaking industry, etc. The dewatering roller is provided with a supporting cylinder, wherein grooves are evenly distributed on the circumference of the cylinder, a multiporous outer ring is sheathed on the outer side of the multi-groove supporting cylinder, baffle plates are assembled on both ends of the multiporous dewatering roller, and a suction nozzle seat and a suction nozzle are assembled and are tightly clung on the corresponding parts of the plans of the baffle plates on the end faces. After the multi-groove supporting cylinder and the multiporous outer ring are assembled, each groove can be an independent vacuum pumping passage. The dewatering roller has two dewatering functions of roller squeeze and vacuum pumping.

Description

Multi-aperture dewatering roller with vacuuming end-face

What the utility model end face vacuum draw porous dehydration roll related to is a kind of industry fiber tinuous production dewater units such as weaving, papermaking that are applicable to.

At present the fiber dewatering roll generally is to be encapsulate at top and bottom rolls, also has below the top encapsulate to enclose for the outer garden of metal roll to be processed with aperture, but owing to does not have the water absorber effect undesirable.Current production devices can't make the fibrage thickness that enters roll dehydration even, thin place roll less than fibrage moisture height, make it the oven dry difficulty, as increase the drying plant that output just needs to increase some, investment is high like this, and the transformation time is long, and floor space need increase.

The purpose of this utility model is to have weak point at present fiber dewatering roll, a kind of end face suction porous dehydration roll is provided, have roll squeezing and two kinds of dehydrating functions of vacuum draw, make the fibrage moisture after the dehydration low and even, very favourable to back operation oven dry, can improve the quality of products by a relatively large margin.

End face vacuum draw porous dehydration roll takes following scheme to realize: end face vacuum draw porous dehydration roll primary structure is made of multiple-grooved support tube, roll mandrel, porous outer ring, space collar, baffle plate, suction nozzle seat, suction nozzle.Support tube is uniform some grooves on the multiple-grooved support tube circumference, and multiple-grooved support tube outer cover is equipped with the porous outer ring, is densely covered with on the porous outer ring to make every groove become independently vacuum draw passage after assemble through hole, multiple-grooved support tube and porous outer ring.Roll mandrel is equipped with at multiple-grooved support tube two ends, and baffle plate is assemblied in porous dehydration roll two ends, and the irregularly-shaped hole number of locations that forms after being processed with some irregularly-shaped holes on the baffle plate and assembling multiple-grooved support tube and porous outer ring is identical.The assembling of suction nozzle seat and suction nozzle is close on the end face baffle plane relevant position with the form of automatic compensation, and the suction nozzle seat is connected with vacuum line.

When end face vacuum draw porous dehydration roll enters the roll press dewatering after to the water treatment of fiber process, at the roll end face with vacuum draw (with the fibrage fabric width fixed one or biend suction), to space between the fiber and fibrage became uneven, as thin place roll roll less than the part fibrage in institute's water content further aspirate, dewater, this is reasonable approach, make fibrage before entering drying plant, reduce moisture and even, very favourable to back operation oven dry, can improve the quality of products by a relatively large margin.Need to change the present patent application roll to only modernizing and expanding the existing factory on original equipment and get final product, relatively invest lowly with increasing drying plant, need not enlarge the place, the time lacks, and cuts down the consumption of energy by a relatively large margin, can reduce equipment investment and factory building area to newly founding the factory.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is an end face vacuum draw porous dehydration roll structural representation.

Fig. 2 is an end face vacuum draw porous dehydration roll cutaway view.

Has multiple-grooved support tube (5) with reference to accompanying drawing end face vacuum draw porous dehydration roll primary structure, the garden of multiple-grooved support tube is evenly equipped with some grooves (10) on week, space collar also is equipped with in the outer garden of multiple-grooved support tube on week, be convenient to from the roll two ends vacuum draw moisture content respectively.Porous outer ring (4) is sleeved on the outside of multiple-grooved support tube (5), and several through holes that gather on the porous outer ring make every groove (10) of multiple-grooved support tube all become independently vacuum draw passage after multiple-grooved support tube and the assembling of porous outer ring.Roll mandrel (11) is assemblied in multiple-grooved support tube two ends, and baffle plate (3) is installed in porous dehydration side, roll two ends, and the irregularly-shaped hole number of locations that forms after being processed with some irregularly-shaped holes on the baffle plate (3) and assembling multiple-grooved support tube and porous outer ring is identical.Suction nozzle (2) is assemblied on the suction nozzle seat (1), and the form with automatic compensation after two assemblings is close on the end face of baffle plate (3), and suction nozzle seat (1) is connected with vacuum line by pipeline.During with reference to accompanying drawing 2 work, when entering end face vacuum draw porous dehydration roll and add, fiber to be drained off (7) carries out pressurizing and dehydrating between the knobbling rolls, aspirate drying zone (9) through vacuum draw fiber water content in the roll squeezing, because fibrage became uneven, particularly fiber thin place roll less than the part fibrage in institute's water content further aspirate dehydration, be convenient to drying plant, oven dry is accelerated to reduce drying plant quantity, accelerates drying time.This roll has roll squeezing and two kinds of dehydrating functions of vacuum draw.

Claims
