Abstract
The utility model relates to a fine grain grading apparatus of an ore dressing industry, which is composed of a sieve frame, and sieve strips which are arranged in the sieve frame in parallel, wherein, the length direction of the sieve strips is provided with rib strips in an equidistant mode. The utility model is characterized in that two corresponding sides of the length direction of the sieve frame are respectively provided with tension ribs; the tension rib at one side of the two corresponding tension ribs is provided with a connecting hole, and the position of the tension rib at the other side corresponding to the connecting hole is provided with a buckled self-lock element; the surface of each sieve strip is provided with a convex-concave face. The utility model has the advantages of simple structure and convenient connection, and prolongs the viscous flow time of sieved materials on a sieve plate, reduces the content of qualified grains in materials on the sieve, and furthermore, enhances sieving efficiency.
Description
The utility model relates to a kind of ore dressing industry fine grading equipment, but especially a kind of sieve sheet that is used for the fixed or tilt adjustable oscillatory type screening plant in inclination angle.
Close-mesh screen sheet is the critical piece in the ore dressing industry fine grading screening plant, Chinese patent 97227094.7 discloses a kind of novel close-mesh screen sheet, this sieve sheet has solved " willow leaf shape " slit that occurs between the grating effectively, screening efficiency is improved, and the employing of buckle has solved connecting hole gap problem between the sieve sheet, but because buckle is outer monomer buckle, need other machine-shaping, the cost height, and connect also cumbersome.
The purpose of this utility model provides a kind of sieve sheet anti-bending strength that increases, and improves service life, assembles the more material viscous flow self-locking close-mesh screen sheet of simple and fast.
Another purpose of the present utility model provides a kind of the prolongation and is sized material viscous flow time on the sieve sheet, further improves the material viscous flow self-locking close-mesh screen sheet of screening efficiency.
The utility model is to realize like this, it is made up of screen frame and the grating that is set in parallel in the screen frame, the equidistant rib that is provided with of the length direction of grating, it is characterized in that on two corresponding edge of length direction of screen frame, being respectively equipped with lacing wire, on a layback muscle of two corresponding lacing wires, be provided with connecting hole, be provided with the buckle self-locking body in the opposite side lacing wire position corresponding with connecting hole, the surface of grating is a male and female face.
The utility model has the advantages that increase is sized the viscous flow time of material at compass screen surface, has reduced the content of qualified particle in the oversize material, has further improved screening efficiency because sieve sheet surface design becomes male and female face.Buckle self-locking body and connecting hole are processed into an integrated member with the sieve sheet respectively in addition, have not only overcome the distortion of sieve sheet, improve service life, have also reduced cost simultaneously, and it is simpler and easy quick that the sieve sheet is linked and packed.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a floor map of the present utility model.
Fig. 3 is the A-A generalized section of the utility model Fig. 2.
Fig. 4 is the schematic perspective view of the utility model grating surface for convex-concave point.
Fig. 5 is that the utility model grating surface is choked flow weir and choked flow ditch schematic perspective view arranged in a crossed manner.
Referring to Fig. 1,2,3, it shows a horizontal screen sheet according to the utility model design, it is made up of screen frame and the grating that is set in parallel in the screen frame, at the equidistant rib 5 that is provided with of the length direction of grating, it is characterized in that on two corresponding edge of length direction of screen frame, being respectively equipped with lacing wire 1, on a layback muscle of two corresponding lacing wires 1, be provided with connecting hole 3, be provided with buckle self-locking body 2 in opposite side lacing wire and connecting hole 3 corresponding positions, whole sieve sheet adopts single injection-molded, as long as after buckle self-locking body 2 being inserted the connecting hole 3 of another piece sieve sheet, just can rapidly the sieve sheet be connected into sieve plate as required.Assemble more simple and fast thereby make, cost is also low.
To be sized material viscous flow time on compass screen surface in order prolonging, further to improve screening efficiency, the surface design of the utility model grating 4 becomes male and female face.Its male and female face can be convex-concave point 6, sees Fig. 4; Also can be designed to the male and female face on choked flow weir 7 and the male and female face of band choked flow ditch 8, can also be designed to male and female face arranged in a crossed manner, see Fig. 5 by choked flow weir 7 and choked flow ditch 8.This scraggly surface texture, increase the roughness on sieve sheet surface, make 4 pairs of gratings on the compass screen surface be sized layering " cutting " effect of material ore pulp bottom generation greater than 90 ° of angles, prolong the viscous flow time of material that is sized relatively at compass screen surface, reduce the content of qualified particle in the oversize material, further improve screening efficiency.
The utility model is simple in structure, and is easy to connect, the screening efficiency height, and long service life can be widely used in the ore dressing industry.
