Abstract
The utility model discloses a kind of head coal sculpingscreen, comprise sieve plate, described sieve plate is provided with sieve aperture, wherein: described sieve aperture is diamond hole; Described sieve plate is square plate, described head coal sculpingscreen comprises feed end and discharge end, the major axis two ends of described diamond hole point to described feed end and described discharge end respectively, and described head coal sculpingscreen is linear vibrating screen, and the coal on diamond mesh and head coal sculpingscreen sieve plate flows away to being arranged in parallel.The head coal sculpingscreen that the utility model provides, by the sieve aperture on sieve plate is set to diamond hole, solves the problem of coal cinder blocking of the prior art, improves screening efficiency, improve the treating capacity of head coal sculpingscreen, reduces the medium loss because blocking causes.
Description
Technical field
The utility model relates to coal preparation technology, particularly relates to a kind of head coal sculpingscreen.
Background technology
In the process of coal preparation, usually need product after sorting to carry out to dewater, de-mediated, classification process, head coal sculpingscreen is the common equipment of dressing of coal by washing.
Existing head coal sculpingscreen comprises sieve plate, and sieve plate is provided with sieve aperture, and sieve aperture 12 ' is strip, as shown in Figure 1.Because the ature of coal of coal cinder is softer, easily locate blocking occurs at sieve aperture 12 '.Along with the vibration of sculping screen, coal cinder understands the more and more tighter of blocking, until blocked completely by sieve aperture.
Above-mentioned head coal sculpingscreen is at normal band coal one hours, and sieve aperture just has 90% to be blocked, and screening efficiency reduces, and the sieve aperture of blocking hinders the speed of travel of coal stream, and the local of compass screen surface there will be the phenomenon of coal cinder accumulation.
Utility model content
The utility model provides a kind of head coal sculpingscreen, to solve the problem of coal cinder blocking in prior art, enhances productivity.
The utility model provides a kind of head coal sculpingscreen, comprises sieve plate, and described sieve plate is provided with sieve aperture, wherein: described sieve aperture is diamond hole.
Head coal sculpingscreen as above, wherein, preferably: described sieve plate is square plate, and described head coal sculpingscreen comprises feed end and discharge end, the major axis two ends of described diamond hole point to described feed end and described discharge end respectively.
Head coal sculpingscreen as above, wherein, preferably: the minor axis dimension of described diamond hole is 13-200mm.
Head coal sculpingscreen as above, wherein, preferably: the minor axis dimension of described diamond hole is 50mm.
Head coal sculpingscreen as above, wherein, preferably: described sieve plate is corrosion resistant plate.
Head coal sculpingscreen as above, wherein, preferably: described head coal sculpingscreen is linear vibrating screen.
The head coal sculpingscreen that the utility model provides, by the sieve aperture on sieve plate is set to diamond hole, solves the problem of coal cinder blocking of the prior art, improves screening efficiency, improve head coal sculpingscreen treating capacity, reduces the medium loss because blocking causes.
Accompanying drawing explanation

The sieve-plate structure schematic diagram of the head coal sculpingscreen that Fig. 2 provides for the utility model embodiment;
Fig. 3 is structure and the scale diagrams of diamond hole.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in detail.
The sieve-plate structure schematic diagram of the head coal sculpingscreen that Fig. 2 provides for the utility model embodiment.As shown in Figure 2, the utility model embodiment provides a kind of head coal sculpingscreen 1, comprises sieve plate 11, sieve plate 11 is provided with sieve aperture 12, and sieve aperture 12 is diamond hole, and this sieve aperture 12 can carry out processing and manufacturing by punching technology.
In the present embodiment, head coal sculpingscreen 1 is linear vibrating screen, coal cinder enters into sieve plate 11 from the feed end of head coal sculpingscreen 1, walk in plate face again along sieve plate 11, in the process of walking, along with the vibration of sieve plate 11, the coal cinder being less than sieve aperture 12 size is screened out, and remaining coal cinder flows out from the discharge end of head coal sculpingscreen 1 again.
The material of sieve plate 11 can be corrosion resistant plate, preferably, sieve plate 11 is square plate, and described head coal sculpingscreen comprises feed end and discharge end, the major axis two ends of the sieve aperture 12 of rhombus point to above-mentioned feed end and discharge end respectively, that is, diamond mesh 12 flows away to being arranged in parallel with the coal on head coal sculpingscreen sieve plate.
The size of the sieve aperture 12 of rhombus can be arranged according to concrete block particle diameter to be screened coal, and as shown in Figure 3, be less than 50mm for coal cinder particle diameter to be sieved, the major axis dimension that can arrange diamond hole is 100-250mm, and minor axis dimension is 13-200mm.Be preferably, major axis dimension is 100mm, and the minor axis dimension of diamond hole is 50mm.Different according to the situation of coal cinder blocking, the size of major axis can be adjusted, therefore at this, concrete restriction is not done to the size of major axis.
It will be appreciated by those skilled in the art that: diamond hole can be arranged to different sizes according to the coal cinder granule size of required classification, as long as the minor axis dimension meeting diamond hole is greater than coal cinder particle diameter to be screened out.
Compared with prior art, when using head coal sculpingscreen of the prior art to carry out clean fine coal grading, if coal cinder particle diameter to be sieved is less than 50mm, the sieve aperture minor axis dimension that therefore can arrange strip is 50mm, and major axis dimension is 100mm.The shape majority of coal cinder is irregular, when coal cinder is walked and is dropped in sieve aperture on compass screen surface, inside the arc surface that can drop to strip sieve aperture time most, its bond area is larger, because ature of coal is softer, at sieve aperture place, spring is just stuck, along with the meeting of the vibrations blocking of sieve plate is more and more tighter coal cinder several times.
Fig. 2 shows structure and the size of diamond hole, as shown in Figure 2, in the present embodiment, the shape of sieve aperture is diamond hole, when coal cinder is walked at compass screen surface and is fallen to diamond hole, and the coal cinder close with screen size, its most of drop point is at the shadow region A of Fig. 2, compare in prior art, the contact area of coal cinder and sieve aperture is less, therefore solves the problem of coal cinder blocking.
Those skilled in the art it will also be appreciated that: sieve aperture can also be set to the punchings such as rectangle, circle, square, but, through verification experimental verification repeatedly, diamond hole for the phenomenon reducing coal cinder blocking, its best results.
The head coal sculpingscreen that the utility model embodiment provides is by being set to diamond hole by the sieve aperture on sieve plate, solve the problem of coal cinder blocking of the prior art, improve screening efficiency, avoid because blocking causes compass screen surface coal stream to pile up, improve treating capacity, avoid unnecessary medium and run off.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
