Abstract

The utility model discloses a turbine pulverizer screen sheet which comprises a circular arc metal plate and meshes arranged on the metal plate, wherein the concave surface of the metal plate is further provided with mill knives which are vertically distributed at intervals, the meshes are located between the mill knives, are distributed in longitudinal grouping, and are arranged in transverse and longitudinal cross, the outlets of the meshes are bigger than the inlets, and the outlets are in a truncated cone shape. As adopting the structural design of the utility model, disintegrated materials leak from the outlets of the meshes after the materials are screened out through the inlets of the meshes after reaching certain grain sizes, thereby shortening the screening stroke, and preventing the meshes from jamming, the opportunities for exchanging and cleaning screen sheet are few, and the discharging rate is high. Furthermore, the bar-shaped mill knives are added on the screen sheet, which enable the screen sheet to have the function of shearing materials, and improve disintegrating efficiency.

Description

The turbine grinder screen stencil sheet

Technical field

The utility model relates to a kind of screen stencil sheet of turbine grinder, be widely used in the discharging of sieving of materials such as the dryness material of various low, the middle hardness in the industry production such as food, chemical industry, medicine, agricultural chemicals, feed, pottery and plastics and thermal sensitivity, belong to size reduction machinery and make the field.

Background technology

So far, the screen stencil sheet that turbine grinder is used, it is a curved steel plate with sieve aperture, this steel plate has certain durability through after the Quenching Treatment, sieve aperture is to arrange along circular arc line in the horizontal, and vertically be staggered and form, the both sides of 6 screen stencil sheets be plugged on that 6 abrading block sides offer groove in, each end of 6 abrading blocks all fixes by screw with a sieve circle, thereby constitutes a sieve spare, and sieve spare is positioned at casing, be fixed in by the installing hole on the sieve circle on the rear wall in the casing of turbine grinder, so when material is ground into certain particle, just spill by passing in the sieve aperture, still unsifted material is proceeded to pulverize.And the turbine grinder of the thin material of pulverizing; the screen stencil sheet that needs corresponding little sieve aperture is suitable; this sieve aperture is the less cylindrical hole of diameter; stop up easily; thereby make the material that should sift out still be trapped in the pulverizing chamber and can't in time pass through; in case screen stencil sheet stops up then needs frequent clean and even replacing; need shut down 1-2 hour and change, clean screen stencil sheet; have a strong impact on production; not only consumptive material but also consume power; and material is slower by the speed of sieve aperture, and the mass output rate of pulverizer is lower, wastes the part electric energy simultaneously also meaninglessly.

Again, conventional screen stencil sheet function singleness does not possess the material of shearing and only used as filter material.

The utility model content

The utility model is at above-mentioned the deficiencies in the prior art, and the screen stencil sheet that provides a kind of mass output rate height, not susceptible to plugging turbine grinder to use makes this screen stencil sheet also have the effect of shearing material.

For reaching above-mentioned purpose, solution of the present utility model is as follows:

The turbine grinder screen stencil sheet, the metallic plate and the sieve aperture that is opened on the metallic plate that comprise circular arc, also has the sharpening that longitudinal separation distributes on the concave surface of metallic plate, sieve aperture be vertically distribute in groups and laterally, vertically be staggered between whetting a knife, the outlet of sieve aperture is greater than inlet, and outlet is round table-like.

Above-mentioned sharpening is the triangle strip, and the inlet of sieve aperture is cylindrical.

The utility model is relative with prior art, and the beneficial effect that the fact has is as follows:

(1) outlet of sieve aperture is designed to round table-like structure, and after just the inlet by sieve aperture sifts out when making the material of having pulverized reach certain particle, i.e. outlet by sieve aperture spills, the stroke that sieves like this shortens, prevent sieve pore blockade, screen stencil sheet transposing, cleaning machine can lack, and mass output rate is higher.

(2) have additional the triangle strip-like-shaped on the screen stencil sheet and whet a knife, make it also have the effect of shearing material, improved crush efficiency.

Description of drawings

Be described further with regard to the utility model below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model screen stencil sheet;

Fig. 2 is the schematic diagram that the utility model screen stencil sheet is erectility;

Fig. 2 A is the sieve aperture partial enlarged drawing among Fig. 2;

Fig. 3 is the structural representation that screen stencil sheet and abrading block are combined into sieve spare.

The specific embodiment

See also Fig. 1, Fig. 2, Fig. 2 A and Fig. 3, it is preferred embodiment of the present utility model, turbine grinder screen stencil sheet 1, the metallic plate 2 and the sieve aperture 4 that is opened on the metallic plate that comprise circular arc, also has the sharpening 3 that longitudinal separation distributes on the metallic plate 2, sieve aperture 4 vertically distributes in groups and laterally, vertically is staggered whetting a knife between 3 and be, and the outlet 4.2 of sieve aperture 4 is greater than inlet 4.1, and exports 4.2 and be round table-like.

Length is 264mm, highly is the metallic plate 2 of 8mm for 165mm, thickness, the inlet 4.1 of sieve aperture 4 is a cylindrical hole, its aperture is 2mm, hole depth is 2.5mm, be positioned at the concave side of metallic plate 2, correspondingly, the outlet 4.2 of sieve aperture is positioned at the convex side of metallic plate 2, sharpening 3 is the triangle strip, is positioned at the concave side of metallic plate 2.

See also Fig. 2 A, chamfer design is carried out in the outlet 4.2 of sieve aperture 4, and forming the degree of depth is the round table-like structure of 1.5mm, outlet 4.2 its angles of sieve aperture are 70 °, fines directly spills through exporting 4.2 after being sifted out by inlet 4.1, has reduced the stroke that sieves of fines, is difficult for plug-hole.

The sharpening of a screen stencil sheet 1 has 11, and sieve aperture 4 has 10 groups, and screen stencil sheet 1 is provided with strip and whets a knife, and makes it also have the effect of shearing material, has improved crush efficiency.

See also Fig. 3 and Fig. 2 A, after screen stencil sheet 1 machines, the both sides of every screen stencil sheet 1 are inserted in the groove 6.1 that adjacent two abrading block 6 sides offer, the two ends up and down of abrading block 6 are fixed together by two screws 7 with each sieve circle 8 respectively, thereby constitute a sieve spare 5, a sieve spare 5 is by 6 screen stencil sheets 1,6 abrading blocks 6, two sieve circles 8 constitute, sieve spare 5 is positioned at the casing of pulverizer, and 4 installing holes 8.1 by sieve circle 8 are fixed on the rear wall in the turbine grinder casing, after the material after the pulverizing reaches certain fineness, inlet 4.1 by the sieve aperture 4 of screen stencil sheet 1 sifts out, and spill through exporting 4.2, prevent sieve pore blockade, reduced the screen stencil sheet transposing, the chance of cleaning, both guarantee to pulverize quality, improved mass output rate again.
