Abstract
The utility model provides a paper pulp washing device, more particularly a modified paper pulp washing device capable of squeezing with alternative double rollers. The device comprises two press rollers, a scraper, an ace-shaped plate, a soleplate shaped like the Chinese character 'shan', a sieve plate and a hydraulic cylinder. A plurality of support partitions are arranged axially inside the two press rollers, and a grid plate is arranged longitudinally on the outer circumference of the plurality of support partitions and connected with the partitions by a plurality of grid plate positioning pieces. An isolating gate is also arranged inside the paper pulp inlet passage. The device has the advantages of simple structure, high accuracy and strength of press rollers, and increased production efficiency.
Description
The utility model relates to a kind of papermaking washing device, particularly a kind of improved pair of roller displacement squeezing wash engine.
The paper industry of present China; its washing device is drum-type vacuum pulp washing machine and horizontal belt vacuum pulp washing machine; its floor space is big; many and the narrow application range of operation; two roll-ins press for extracting juice wash engines of Sweden are introduced in 98 years Jiamusi; although collecting one section concentrates; two sections displacement washings; three sections extruding are one; make multiple operation and be a machine; volume is little; but there is a big difference for the actual conditions of it and China's paper-making pulping industry; can not wash thick slurry, and because workspace pressure is generally 0.08～0.1Mpa more greatly, the intensity of pressure roller and precision are all not high; easily cause to shut down to stop production, reduce its production efficiency.
The purpose of this utility model just is to solve the problem of above-mentioned existence, provides a kind of scope of application wider, the improved pair of roller displacement squeezing wash engine that pressure roller intensity and precision are higher.
The technical solution of the utility model is to realize like this, this machine is made up of pressure roller, scraper, arc, chevron base plate, sieve plate and hydraulic cylinder, be axially arranged with a plurality of supporting clapboards along mandrel in two pressure rollers, on the periphery of a plurality of supporting clapboards, vertically be provided with screen, screen and dividing plate are connected as a single entity by a plurality of screen locating pieces, also are provided with barrier in the runner advancing to starch.
This utility model project organization is simple, and pressure roller intensity and precision are higher, and be applied widely, is difficult for causing shutting down the stopping production phenomenon, and production efficiency improves greatly.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the schematic diagram of pressure roller shown in Figure 1;
Fig. 3 is that A-A shown in Figure 2 is to cutaway view;
As shown in the figure: this machine is by sealing scraper 12 arcs 5 on sealing scraper 3 under 11, two groups of fixedly pressure roller 1 and the mobile pressure rollers and two groups, chevron base plate 7, and sieve plate 15, hydraulic cylinder 9 is formed.Roller 1 and 11 all is installed on the middle casing by bearing block, the axis of roller 1 is fixed, roller 10 can move along horizontal slideway, one end of roller is equipped with hydraulic motor, the other end then is equipped with the gear of forced synchronism rotation, do not show synchromesh gear among Fig. 1, the rotation of rotor drives by the large torque low speed fluid motor; Mobile roller move horizontally and two rollers between square determine finish by moving horizontally four fluid cylinders, the upper end of arc 5 is fixed on the middle casing by rotary pin joint, its top and chevron base plate 7 overlap naturally, regulate bolt 10 arc is moved, and it is fixed.
Advance to starch the slurry that runner 4 enters from the machine both sides, at first by barrier 14, thicker impurity is blocked, and by at first arriving enrichment region, it is a space section that can change that is formed by arc 5 and roll surface to slurry smoothly, and changing size can adjust.The slurry that is concentrated enters the displacement washing district with the rotation and the interior shell pressure of roller, from the spray mouth of pipe penetrate high pressure by two washings import 6 of chevron base plate factory this moment, and (0.3～0.4Mpa) worker's shower water washs the slurry layer, thereby reach the effect of washing displacement, then the chevron base plate pushes pressed zone to slurry, up to 30-40%, the square size is adjusted and controlled between rotating speed that the concentration of slurry can be by roller and two rollers through the slurry concentration after the squeezing.
Because in the wash engine course of work, all the time be in and be closed with pressure condition, pressure is 0.08～0.1Mpa, thereby roller need bear the pressure of 35g～45kgf/cm, therefore pair of rollers intensity proposes higher requirement, we axially are provided with a plurality of supporting clapboards 16 along mandrel 18 in two rollers for this reason, improve roller intensity, on the periphery of a plurality of supporting clapboards 16, vertically be provided with screen 20, and dividing plate and screen are connected as a single entity by a plurality of screen locating pieces 19, this has not only improved positioning accuracy, has improved the intensity of roller again, improves the production efficiency of complete machine greatly.
