Abstract
The utility model discloses a special-shaped screen board, which relates to a sheet and a board or other similar elements. The special-shaped screen board is suitable for screening and filtering dissolving pulp with a finite concentration in a paper-making machine and a food machine. The special-shaped screen board is provided with concave pits with various dimensions, lug bosses with various dimensions and circular or seam-shaped screen meshes on a screen board surface. The special-shaped screen board which is a stainless steel thin board can be made into a flat board, or a cylinder, or various arc shapes and curved surfaces. The surface of the flat board is concave and convex. The special-shaped screen board can improve pulp density and production capacity and save water, and can also improve the quality of screening and filtering. For the paper pulp, the special-shaped screen board can intensify the fluffing function of pulp fibre.
Description
The utility model relates to sheet, plate; Or other likes.
Various pressurized screens, the screen centrifuge that uses at present in the pulp and paper industry machinery, the frame that shakes sieve, and round-hole punched plate, the slit sieve plate of adapted in other vibrating screens, two face is flat surface, and with the paper pulp of this sieve plate screening, it is all lower to advance to starch concentration, throughput (output), screening effeciency.
The purpose of this utility model is that a kind of raising of design advances to starch concentration, output and screening effeciency to improve the novel sieve plate of finished product paper quality, bump and the principle of turbulization effect and fluidization after entering the utility model Profile sieve plate according to paper pulp, because fiber, fibre bundle (lumps) and different specific weight that impurity has and weight in the paper pulp, under turbulent flow and fluidization, the effect that good slurry separates with impurity is strengthened, thereby improved output and screening effeciency, and aggravated the effect of discongesting of fiber because of the effect of boss pit.Between hole on the sieve plate face and seam, be processed into various ups and downs shapes, according to various characteristics of pulp and various uses, can select corresponding specification for use, to satisfy instructions for use.
Sieve plate is a sheet metal, and its hole, seam and pit boss are all made with punch process.
Accompanying drawing 1 is the cutaway view of the with holes and boss of the Profile sieve plate of utility model, pit.Fig. 2 and Fig. 3 be the A of Fig. 1 to launching view, Fig. 4 be the cutaway view of another kind of embodiment, Fig. 5 is that the A of Fig. 4 is to the expansion view.1 is that boss (pit), 2 is sieve aperture, sieve seam among the figure.
Provide embodiment of the present utility model in conjunction with the accompanying drawings.
Profile sieve plate is a stainless sheet steel, and material can be stainless sheet steels such as I Cr18N19Ti commonly used at present, and thickness is advisable with 1～2mm.Sieve plate can be made into concave-convex surface (the utility model Profile sieve plate as shown in Figure 1, be boss type when paper pulp flows out from top to bottom, when flowing out from bottom to top, be pit type) plate.Cylinder type, various arcs and curved surface.Sieve aperture and male and fomale(M﹠F) adopt cold-punching molding, polish after the punch process.Accompanying drawing 1 and accompanying drawing 2 have provided the Profile sieve plate of a kind of ball bumps type boss (pit) and round sieve, accompanying drawing 1 and accompanying drawing 3 have provided the Profile sieve plate of a kind of bar-shaped boss (pit) and seam shape sieve aperture, accompanying drawing 4 and accompanying drawing 5 provide the Profile sieve plate of a kind of zigzag boss (pit) and seam shape sieve aperture, one-tenth capable of being combined in addition bar-shaped or zigzag boss (pit) and circular hole, in conjunction with and spherical boss (pit) and sieve seam give the various Profile sieve plates that close, wherein the sieve aperture shape is mainly decided according to the characteristic and the length of paper pulp fiber.
Sieve aperture, sieve seam are decided according to the characteristic and the purposes of different paper pulp with the array format of pit, boss therebetween.Can be cross arrangement in a row, also can be alternate cross arrangement.
The utility model Profile sieve plate uses through reality, and positive effect is arranged, the advancing to starch concentration and can increase to 4% of paper pulp. (common sieve plate is about 2%) improved output, saved water, and kowtows Jie's degree because of what the aggravation of the effect of discongesting had improved paper pulp. From the screenings of discharging, detect, very starch content and obviously reduce, improved the yield of paper pulp and the quality of good slurry.
The utility model also can be applicable in the screening installation of food processing except using in pulp and paper industry.
Claims (3)
1. Profile sieve plate, it is formed by the stainless-steel sheet punch process, has round sieve, it is characterized in that making on the sieve plate face spherical or jagged pit of strip or boss, and sieve aperture circular or seam shape.
2. according to the said Profile sieve plate of claim 1, it is characterized in that pit, boss and hole, seam are cross arrangements in a row.
