Abstract
The utility model relates to a pulp pressure pre-dehydration device for a double-net washing engine, which comprises a transmission device and a pulp inlet port. The bottom surface of the pre-dehydration device is a bottom net which is supported by a supporting roller, and the top surface of the pre-dehydration device is a top net, the upper surface of which is connected with a pressure roller. Closed plates are respectively connected between the end faces of pulp inlets on the top net and the bottom net and between both side end faces of the top net and the bottom net. A closed port is formed in the position of pulp outlets of the top net and the bottom net. When the utility model is used, after pulp enters a closed drying zone, the pulp is dewatered simultaneously under the gravity and the squeezing action of the top net and the bottom net. The utility model has a favorable dewatering effect, and has no need of using elements, such as a vacuum pump. Therefore, the service life of the nets can be prolonged, and the utility model does not have any lower limit demand on the concentration of pulp.
Description
Technical field
The utility model relates to papermaking equipment equipment, specifically a kind of double-screen pulp-washing machine pulp pressure pre-dehydration device.
Background technology
Paper industry needs paper pulp is dewatered in pulping process.Present dewatering of pulp device mostly is to rely on many two rollers to be carried out press dewatering to the paper pulp in two nets, this dewatering type is higher to advancing to starch concentration requirement owing to there is not to solve pair sealing problem of the interior slurry of net, generally can not be lower than 2%, otherwise can cause a large amount of losses of slurry or declining to a great extent of output; And pulp concentration is lower, and general being difficult to surpasses 30%; Power consumption is higher; The device structure complexity; Hard block in the slurry very easily damages shortcomings such as pressure roller and net.And another kind of newer dewater unit is that upper and lower net is installed in a wedge area, by power suction dehydration, though this device has improved dehydrating effect, and there is not the lower limit requirement to advancing to starch concentration, but power consumption is big, complex structure, service life of net is short, and the variation of advancing to starch concentration is to shortcomings such as the influence of output and pulp concentration are too big.
Summary of the invention
The purpose of this utility model is to design a kind of simple in structure, and dehydrating effect is good, and advancing to starch concentration can be very low, without vavuum pump, so the extremely low a kind of double-screen pulp-washing machine pulp pressure pre-dehydration device of power consumption.
The utility model is finished as follows: a kind of double-screen pulp-washing machine pulp pressure pre-dehydration device, comprise actuating unit, stock inlet (1) and bottom surface are off line (3) and the online of being supported by carrying roller (2) (4), it is characterized in that the online (4) above be connected with pressure roller (5), horizontal end face that described online (4) and off line (3) form in charging aperture (1) place and two upright end faces of both sides all be connected with and surf the Net (4), the sealing plate (6) that off line (3) directly contact, described sealing plate is " [" type, " two horizontal flexibility plates on [" type sealing plate are under slurry pressure, can fit to online up and down automatically, thereby the slurry in two nets is formed sealing, described online (4), off line (3) are left sealing plate (6) at slurry and are located to rely on backing roll (8) to form seal (7).
The utility model in use, after slurry is pressed into by stock inlet (1), in online (4), " [" type and online (4) that off line (3) formed charging aperture end face and both sides end face are provided with, off line (3) directly contact sealing plate (6) and in the slurry of online (4) and off line (3) clamping leaves the seal-off pressure chamber of the seal (7) that sealing plate (6) forms, dewater by (4) and off line (3) the two-sided pressure of surfing the Net, its dehydrating effect is good, and it is simple in structure, do not need to use dewatering elements such as vavuum pump, power consumption is extremely low, it only is the less than 1/10 of like product, and there is not the lower limit requirement to advancing to starch concentration, and service life that can prolong net more than three times, easy to use.
