Abstract
The invention discloses a screening basket for coal classification, and in particular discloses a screening basket of a centrifugal dehydrator which is used for dehydrating classified products in a wet method coal classification plant. According to the screening basket, screening bars are perpendicular to an axis of the screening basket and are supported by using support bars; the arranging direction of the support bars is the same as the axis direction; and the screening basket formed by welding the screening bars with the support bars is an overall conical structure. Due to the unique arrangement direction of the screening bars and the support bars, the defects that cutting resistance is generated from opposite motion of screening bar edges and a scrapping knife and the screening seam is shielded are reduced, and the aperture ratio is improved; and meanwhile the screening surface of the screening basket is integrally shaped without splicing, so that the precision is improved, the seam between a screening surface and a scarper is reduced, the remaining on the screening surface is reduced, the screening seam has less block, the dehydration efficiency is improved, and the load is reduced; and meanwhile the corrosion of the screening basket surface is reduced, and the service life of the screening basket is prolonged.
Description
Technical field
The present invention relates to a kind of coal separation basket, the centrifugal dehydrator basket that product dehydrate is used after selecting especially for wet coal preparation factory.
Background technology
The structure of existing centrifugal dehydrator basket is seen Fig. 4-5, this rich axle center revolution of taper basket with compass screen surface.Product feeds the top of basket after the choosing, is subjected to centrifugal action, and the moisture that product is taken sees through compass screen surface and discharges, and product is then scraped in the centrifuge lower hopper by epitrochanterian scraper, realizes Separation of Solid and Liquid.The basket of the Multiple Type of reality production usefulness, all adopt and will weld that good stainless steel mesh cylinder launches, cutting, splice after again welding fabrication be conical basket, the grating of this basket is all arranged along axis, support bar is arranged perpendicular to axis.
Can find out from the existing basket production process of Fig. 4-5, existing basket is the sieve spicing forming type of six perpendicular gratings.Its weak point is: splicing place is because welding and strain, can not reach the circularity that requires of basket, the fit clearance part of working face and scraper is inhomogeneous at work to cause basket, dehydrated material retains uneven thickness on basket, to adhere to the material that one deck does not fall on the compass screen surface, the material of dehydration can only slide along the residue bed of material, has increased resistance, load is increased, and power consumption is large.Cause simultaneously the fragmentation of material, because the scraper local influence has blocked the draining of basket bar seam, reduced the percent opening of basket, thereby reduced dehydrating effect, and because existing basket making is complicated, and operation is many, so production cost also significantly increases.
Summary of the invention
Goal of the invention of the present invention is large for existing basket resistance, and load increases, power consumption
Greatly, costs and poor dehydration results is made complicatedly, and the defectives such as production cost height provide a kind of centrifugal dehydrator basket of whole conical structure of continuous welding.
Realize the foregoing invention purpose by the following technical solutions:
A kind of centrifugal dehydrator basket, comprise grating, support bar, screen frame, grating, support bar are arranged according to the order of sequence and are positioned at screen frame, the axis of described grating and basket is perpendicular, support with support bar, the support bar arragement direction is identical with axis direction, and the basket behind grating and the support bar welding fabrication is whole conical structure.
As preferred version, described grating is laterally arranged, and support bar is vertically arranged, and places in the screen frame, and each intersection point of grating and support bar all is solder joint.
As preferred version, described grating is equidistantly laterally arranged, and support bar is equidistantly vertically arranged.
As preferred version, the grating diameter is 2.4-3.2 ㎜, and the support bar diameter is 3.2-5.3 ㎜.
Adopt technique scheme, compared with prior art, the grating direction of basket of the present invention is horizontal (perpendicular to the axle center), and support bar is vertical, this arranging reduced Edge of screen bar and scraper the relative motion Cutting Drag that produces and the shortcoming of blocking the sieve seam, improved percent opening.Simultaneously, the basket compass screen surface is global formation, without splicing, has improved precision, has dwindled the slit of compass screen surface and scraper, has reduced the compass screen surface retentate, the sieve seam is blocked few, and dewatering efficiency improves, and has reduced load.Reduce simultaneously the wearing and tearing of basket face, improved service life.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
A kind of centrifugal dehydrator basket, the structure of this basket is seen Fig. 1, Fig. 2, be comprised of screen frame 1, grating 2, support bar 3, grating 2 is equidistantly laterally arranged with the axis of basket is perpendicular, supports with support bar 3, the arragement direction of support bar 3 is identical with axis direction, support bar 3 is equidistantly vertically arranged along axis direction, places in the screen frame 1, and grating 2 all is solder joint with each intersection point of support bar 3.Firm supporting, pulling force is large.See Fig. 3, the basket behind grating 2 and support bar 3 welding fabrications is whole conical structure 4.The transverse and longitudinal arragement direction of grating 2, support bar 3 has reduced Edge of screen bar and scraper the relative motion Cutting Drag that produces and the shortcoming of blocking the sieve seam, has improved percent opening.
It is the steel wire of 2.4-3.2 ㎜ that grating 2 of the present invention is selected diameter, and it is the steel wire of 3.2-5.3 ㎜ that support bar 3 is selected diameter.The grating 2 of the present embodiment is selected the steel wire of 2.8 ㎜, and support bar 3 is selected the steel wire of 4.4 ㎜.Grating 2 is reasonable with support bar 3 collocation, and the sieve seam is arranged evenly.
The basket of whole conical structure 4 has overcome such as Fig. 4, prior art shown in Figure 5 and has welded the complicated procedures of forming such as expansion, cutting, splicing, moulding, has realized goal of the invention.
The present invention has applied for utility model patent on the same day with identical theme.
