Abstract
The utility model provides a screening basket for coal selection and particularly provides a screening basket of a centrifugal dehydrator for dehydration of selected products in a wet method coal preparation plant. Screening strips are perpendicular to the axis of the screening basket and are supported through support strips, the arrangement direction of the support strips is identical to the axis direction, and the screening basket formed by welding the screening strips and the support strips is of an integral cone structure. Due to the unique arrangement direction of the screening strips and the support strips, cutting resistance and screen gap blocking produced by relative movement of grate bar edges and a scraper are reduced, the opening percentage is improved. In addition, the screening face of the screening basket is integrally formed and free of splicing, the accuracy is improved, a gap between the screening face and the scraper is reduced, retentate on the screening face is decreased, blocked screen gaps are decreased, the dehydration efficiency is improved, and the load is reduced. Furthermore, abrasion of the screening basket face is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of coal separation basket, especially for the centrifugal dehydrator basket of wet coal preparation factory choosing back product dehydration usefulness.
Background technology
The structure of existing centrifugal dehydrator basket is seen Fig. 3-4, this taper basket rich axle center revolution that has compass screen surface.Choosing back product feeds the top of basket, 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 model 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.
From the existing basket production process of Fig. 3-4 as can be seen, existing basket is the sieve sheet 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 big.Cause the fragmentation of material simultaneously, 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 utility model is big at existing basket resistance, and load increases, and power consumption is big, and costs and poor dehydration results is made complicatedly, and 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 the utility model basket is horizontal (perpendicular to the axle center), and support bar is vertical, this arranging reduced grating arris and scraper relative motion the cutting resistance that produces and the shortcoming of blocking the sieve seam, improved percent opening.Simultaneously, the basket compass screen surface is global formation, does not have splicing, has improved precision, has dwindled the slit of compass screen surface and scraper, has reduced the compass screen surface retentate, and it is few that the sieve seam is blocked, and dewatering efficiency improves, and has reduced load.Reduce the wearing and tearing of basket face simultaneously, improved service life.

Among the figure, screen frame 1, grating 2, support bar 3, cone structure 4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of centrifugal dehydrator basket, the structure of this basket is seen Fig. 1, Fig. 2, be made up 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 big.The transverse and longitudinal arragement direction of grating 2, support bar 3 has reduced grating arris and scraper relative motion the cutting resistance that produces and the shortcoming of blocking the sieve seam, has improved percent opening.See Fig. 3, the basket compass screen surface that is welded to form by grating 3 and support bar 3 is structure as a whole, and the basket behind grating 2 and support bar 3 welding fabrications is whole conical structure 4.
It is the steel wire of 2.4-3.2 ㎜ that grating 2 of the present utility model is selected diameter for use, and it is the steel wire of 3.2-5.3 ㎜ that support bar 3 is selected diameter for use.The grating 2 of present embodiment is selected the steel wire of 2.8 ㎜ for use, and support bar 3 is selected the steel wire of 4.4 ㎜ for use.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 complicated procedures of forming such as prior art welding expansion as shown in Figure 3, Figure 4, cutting, splicing, moulding, has realized goal of the invention.
The utility model has been applied for patent of invention on the same day with identical theme.
