Abstract
The utility model relates to a paper pulp washing and dewatering device in paper making industry, in particular to a paper pulp washing and dewatering evacuation device of sheet paper, wherein the bottom part of a compressing paper pulp receiving groove is connected with a vacuum pump. When the paper pulp liquid is driven into the filtering net board, a large quantity of water is filtered by the filtering net board, the residual water is absorbed in the paper pulp by the vacuum pump, and more than 70% water can be desiccated without expression, thereby the effect of the paper surface's natural irregularity can be kept. And the filter net board with paper pulp is took out to dry and dewater with hot wind, the dewatering efficiency is high and the speed is fast, the filter net board can be changed according to the net hole size. The utility model is simple in structure and low in costs, which is applicable for paper making industry.
Description
Technical field:
The utility model relates to paper-making industry pulp washing dehydration equipment, specifically refers to a kind of sheet paper pulp washing vacuum hydroextractor.
Technical background:
In pulp and paper industry, the pulp washing dehydration equipment of prior art generally is with power-actuated cylinder thickener, Kamyr filter etc., its filter mesh is generally 40 orders, the electric energy height that this kind equipment not only consumes, and the efficient of dehydration is low, to use a large amount of clear water to clean the paper pulp filter screen simultaneously, therefore all there is bigger waste aspect electric energy and the water resource, and the said equipment is in order to reach better dehydrating effect, tend to so just destroy the molding effect of paper surface by squeezing this operation.In addition, these equipment can not adapt to the condition that has a large amount of staple fibres and paper pulp composition complexity in the paper pulp, be in operation cause mesh to stop up easily or fiber loss excessive, therefore just can't use when shared ratio reaches 50% in paper pulp fiber when waste paper fibre, can not be suitable for the various types of paper of manufacturing.And drainage rate is slow, is unfavorable for the raising of paper-making industry output, also is unfavorable for the running of next step operation.
The utility model content:
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and provide a kind of sheet paper pulp washing vacuum hydroextractor, this Water Extraction Machinery does not need the water consumption flushing, need not be by squeezing, reach dehydration more than 70%, and can not destroy the surface forming effect of paper, be applicable to make and contain the higher paper of waste paper fibre ratio.
In order to achieve the above object, the utility model adopts following technical scheme:
Sheet paper vacuum hydroextractor of the present utility model comprises support body, screen pack, thicken pulp receiving slit, and it is characterized in that: the bottom of thicken pulp receiving slit is provided with water discharge outlet, and water discharge outlet is connected with vavuum pump by water pipe; Screen pack is located at the top that matches the thicken pulp receiving slit with it.
The filter mesh of described screen pack is 50 orders～120 orders.
Described thicken pulp receiving slit is the hollow back taper.
From technique scheme as can be seen, sheet paper vacuum hydroextractor of the present utility model, bottom at the thicken pulp receiving slit is connected with vavuum pump by water pipe, when the paper pulp dope is poured on the screen pack, screen pack filters a large amount of moisture content, vavuum pump siphons away moisture content remaining in the paper pulp again, just can not reach dehydration more than 70% by squeezing like this, has kept the rough naturally effect in surface of paper; Can take out the screen pack of band paper pulp then and carry out hot-air seasoning dehydration, dewatering of pulp efficient height, speed is fast, the mesh size that screen pack can be as required and changing.The utility model is simple in structure, the cost cost is low, can be widely used in paper-making industry.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a schematic appearance of the present utility model.
The specific embodiment:
See shown in Figure 1ly, be the utility model one embodiment, comprise support body, screen pack 10, thicken pulp receiving slit 11, the bottom of described thicken pulp receiving slit 11 is provided with water discharge outlet 111, and water discharge outlet 111 is connected with vavuum pump 12 by water pipe; Screen pack 10 is located at the top that matches thicken pulp receiving slit 11 with it.This Water Extraction Machinery saves energy, the paper pulp dope relies on the gravity of self to fall by screen pack 10, in this process, most of water in the paper pulp falls into thicken pulp receiving slit 11 together with contained fine impurities by mesh, simultaneously, the wind-force moisture content that paper pulp on the screen pack 10 is residual that vavuum pump 12 runnings produce also siphons away major part, just can not reach dehydration more than 70% like this by squeezing, the rough naturally effect of final maintenance paper surface, thus reach purpose high-speed, high-efficiency dehydration.
If the aperture of screen pack 10 mesh is less than 120 orders, then moisture content is slow excessively through the speed of screen pack 10, the requirement that does not reach dehydration and go out impurity; If greater than 40 orders, then the loss of paper pulp fiber is too much with the aperture of mesh.Therefore the pore size with screen pack 10 is defined as between 50 orders～120 orders, preferred 80 orders～100 orders, and the papery of creating like this is solid, durable, meets people's demand.
Described thicken pulp receiving slit 11 is the hollow back taper, and the quick row who is beneficial to paper pulp dope moisture content leads, and this structure is saved manufacturing cost.
Certainly; the above embodiment only is preferred embodiment of the present utility model; therefore do not limit protection domain of the present utility model,, all should be covered by in the protection domain of the present utility model so the equivalence that all shapes according to the utility model, structure and principle are done changes.
