Abstract
The utility model relates to a kind of gravity flow screen with triangle line screen cloth, comprise the frame being formed by sieve upper plate, sieve side plate, vertical support plate and bottom screening plate, be arranged on feed pipe, material-dividing groove in frame, be arranged on the front retainer plate of frame lower and be arranged on the screen cloth in frame, it is characterized in that: equidistantly in described frame be provided with one group of horizontal support plate, described screen cloth is triangle line screen cloth, and the lower edge of one group of described horizontal support plate is cemented on the slope of vertical support plate; The upper edge of horizontal support plate withstands on the top interior angle of triangle line of triangle line screen cloth.The utility model has the advantages that: the open-work area that is greater than ordinary flat screen cloth due to the open-work area of triangle line net is 1/3rd, therefore, compares the screening efficiency that can improve 1/3rd with equal equal-sized sieve bend.
Description
Technical field
The utility model relates to a kind of mine mechanism technical field, especially relates to a kind of gravity flow screen with triangle line screen cloth.
Background technology
At present; known arc gravity flow screen comprises the frame being comprised of sieve upper plate, sieve side plate, vertical support plate and bottom screening plate; be arranged on feed pipe, material-dividing groove in frame; be arranged on the front retainer plate of frame lower; compass screen surface becomes level install or tilt to be arranged on; its screen cloth adopts ganoid arc compass screen surface; because ore pulp longitudinally directly flows by curved surfaces; in screening process; some thoroughly the fine sand of sieve aperture sneak among coarse sand granule, emit, so wasted widely the energy; reduce screening efficiency, this is the problem in ore pulp screening.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, and convenient operation can improve a kind of gravity flow screen with triangle line screen cloth of screening efficiency.
The purpose of this utility model realizes by following technical proposals:
A kind of gravity flow screen with triangle line screen cloth of the present utility model, comprise the frame being formed by sieve upper plate, sieve side plate, vertical support plate and bottom screening plate, be arranged on feed pipe, material-dividing groove in frame, be arranged on the front retainer plate of frame lower and be arranged on the screen cloth in frame, it is characterized in that: equidistantly in described frame be provided with one group of horizontal support plate, described screen cloth is triangle line screen cloth, and the lower edge of one group of described horizontal support plate is cemented on the slope of vertical support plate; The upper edge of horizontal support plate withstands on the top interior angle of triangle line of triangle line screen cloth.
The quantity of one group of described horizontal support plate is identical with the number of triangle line screen cloth triangle line.
The utility model has the advantages that: in ore pulp flows into feed pipe and material-dividing groove, the rectangular opening of ore pulp below material-dividing groove front side board, eject, ore pulp moves through the domatic of triangle line of screen surface, the open-work area that is greater than ordinary flat screen cloth due to the open-work area of triangle line net is 1/3rd, therefore, compare the screening efficiency that can improve 1/3rd with equal equal-sized sieve bend.
Accompanying drawing explanation
Fig. 1 is to be structural representation of the present utility model.
Fig. 2 be Fig. 1 top view.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.
As shown in Figure 1-Figure 3, a kind of gravity flow screen with triangle line screen cloth of the present utility model, comprise the frame being formed by sieve upper plate 3, sieve side plate 4, vertical support plate 7 and bottom screening plate 9, be arranged on feed pipe 1, the material-dividing groove 2 of upper rack, be arranged on the front retainer plate 8 of frame lower and be arranged on the screen cloth 5 in frame, it is characterized in that: equidistantly in described frame be provided with one group of horizontal support plate 7, described screen cloth 5 is triangle line screen cloth, and the lower edge of described horizontal support plate 7 is cemented on the slope of vertical support plate 6; The upper edge of horizontal support plate 7 withstands on the top interior angle of triangle line of triangle line screen cloth.The quantity of one group of horizontal support plate 7 described in the utility model is identical with the number of triangle line screen cloth triangle line.In the time of in ore pulp flows into feed pipe and material-dividing groove, the rectangular opening of ore pulp below material-dividing groove front side board, eject, ore pulp moves through the domatic of triangle line of screen surface, because the open-work area of triangle line net is greater than the open-work area 1/3rd of flat screen, with existing with treating that the identical sieve bend of size compares, triangle line screen cloth can improve 1/3rd screening efficiency, and also can save on year-on-year basis electric energy is 1/3rd.
Claims (2)
1. the gravity flow screen with triangle line screen cloth, comprise the frame being formed by sieve upper plate, sieve side plate, vertical support plate and bottom screening plate, be arranged on feed pipe, material-dividing groove in frame, be arranged on the front retainer plate of frame lower and be arranged on the screen cloth in frame, it is characterized in that: equidistantly in described frame be provided with one group of horizontal support plate, described screen cloth is triangle line screen cloth, and the lower edge of one group of described horizontal support plate is cemented on the slope of vertical support plate; The upper edge of horizontal support plate withstands on the top interior angle of triangle line of triangle line screen cloth.
2. the gravity flow screen with triangle line screen cloth according to claim 1, is characterized in that the quantity of one group of described horizontal support plate is identical with the number of triangle line screen cloth triangle line.
