Abstract

The utility model discloses a screen plate which comprises a screen plate frame (1) and a screen mesh (2) fixedly arranged on the screen plate frame (1). The screen mesh (2) is formed by welding longitudinal screen bars (3) and transverse screen bars (4) in a 90-degree meshed arrangement manner, the cross section of each of the longitudinal screen bars (3) and the transverse screen bars (4) is formed by combining a lower trapezoid with an upper arch. When the screen plate is used, screen gaps of the screen mesh are slowly changed, separation precision of materials is ensured, use cycle is prolonged, maintenance and replacement costs are reduced, and the labor intensity of workers is relieved.

Description

A kind of sieve plate

Technical field

The utility model relates to the parts on the screening plant, and what be specifically related to is to the sieve plate on the screening installation of materials such as ore, coal and building materials.

Background technology

Screening operation is the important step of some material processing, and it is widely used in industries such as coal, chemical industry, metallurgy, and material is carried out grading, dehydration, desliming and de-mediated.Material to be drained off is applied to the screen surface of sieve plate during work, and frictional force is very big, and traditional sieve plate wearing and tearing are mainly the wearing and tearing of grating; The grating transverse shape is a triangle, causes the sieve seam between adjacent two gratings to increase comparatively fast after the wearing and tearing, has reduced the separation accuracy of material; Cause the life cycle of basket shorter; Change frequently, both increased production cost, increased the weight of working strength of workers again.

Summary of the invention

The utility model purpose is to solve the aforementioned problems in the prior, and a kind of sieve plate of long service life is provided.

The utility model is for achieving the above object; The technological means that is adopted is; A kind of sieve plate comprises sieve plate framework and screen cloth, is fixed with said screen cloth on the said sieve plate framework; To be vertical grating be 90 ° of netted arrangements with horizontal grating to said screen cloth is welded to form, and the arch that the cross section of said vertical grating and said horizontal grating is the trapezoidal and top of bottom combines.

As preferably, said vertical grating and said horizontal grating all select for use no magnetic abrasion-proof stainless steel to process.

As preferably, said sieve plate framework selects for use polyurethane material to process.

The utility model beneficial effect is: simple in structure; The arch that the cross section of vertical grating and horizontal grating is the trapezoidal and top of bottom combines; Make the variation of sieve seam of sieve plate screen cloth in the process of using slower, guarantee the separation accuracy of material, and prolong life cycle; Reduce maintenance and replacement cost, also alleviated working strength of workers simultaneously.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the utility model structural representation;

Fig. 2 is the cross-sectional view in the utility model.

Fig. 3 is the vertical grating and the horizontal cross-sectional configuration sketch map of grating in the utility model.

Among the figure: 1, sieve plate framework, 2, screen cloth, 3, vertical grating, 4, horizontal grating, 5, the sieve seam.

The specific embodiment

A kind of embodiment as the utility model; Like Fig. 1, Fig. 2 and a kind of sieve plate shown in Figure 3; Comprise sieve plate framework 1 and screen cloth 2; Be fixed with said screen cloth 2 on the said sieve plate framework 1, said screen cloth 2 is welded to form for vertical grating 3 is 90 ° of netted arrangements with horizontal grating 4, and the arch that the cross section of said vertical grating 3 and said horizontal grating 4 is the trapezoidal and top of bottom combines.

Said vertical grating 3 all selects for use no magnetic abrasion-proof stainless steel to process with said horizontal grating 4, makes sieve seam 5 be difficult for stopping up.

Said sieve plate framework 1 selects for use polyurethane material to process, and polyurethane material has light weight, good springiness, damping capaicty is strong and anti-wear performance is good advantage.

Material to be drained off is applied to screen cloth 2 surfaces of sieve plate during work, and the arch that the cross section of vertical grating 3 and horizontal grating 4 is the trapezoidal and top of bottom combines, the material elder generation to be drained off and the trapezoidal portions friction of the bottom of vertical grating 3; Worn and torn up to trapezoidal portions, sieve seam 5 can not become big, further uses again; Can may wear to the top arcuate part in the cross section of vertical grating 3, may wear to a certain degree after, sieve seam 5 just can obviously become greatly; Thereby the variation of sieve plate sieve seam 5 in the process of using is slower, guarantees the separation accuracy of material, and prolongs life cycle; Reduce maintenance and replacement cost, also alleviated working strength of workers simultaneously.

The above; Be merely the specific embodiment of the utility model, be not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses; Can expect easily changing or replacement, all should be encompassed within the protection domain of the utility model.

Claims

1. sieve plate; Comprise sieve plate framework (1) and screen cloth (2); Be fixed with said screen cloth (2) on the said sieve plate framework (1); Said screen cloth (2) is welded to form for vertical grating (3) and horizontal grating (4) are 90 ° of netted arrangements, and it is characterized in that: the arch that the cross section of said vertical grating (3) and said horizontal grating (4) is the trapezoidal and top of bottom combines.

2. sieve plate according to claim 1 is characterized in that: said vertical grating (3) all selects for use no magnetic abrasion-proof stainless steel to process with said horizontal grating (4).
