Abstract
The utility model discloses an arc-shaped screen mesh which comprises an arc-shaped screen mesh frame (1) and a plurality of screen bars (2). The screen bars (2) are evenly inclined to the bottom end of the arc-shaped screen mesh frame and are welded on the arc-shaped screen mesh frame (1), and an included angle ranging from 5 degrees to 10 degrees is formed between the bottom surface (21) of each screen bar and a tangent surface of a corresponding welding spot (3) on the arc-shaped screen mesh frame (1). The arc-shaped screen mesh is simple in structure, porosity is increased, shaper scrap edges are formed, material cutting capacity is enhanced, high separation rate can be obtained, and screen gaps can be furthest prevented from being blocked.
Description
Technical field
The utility model relates to the parts on the screening plant, and what be specifically related to is to the curved screen 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.Traditional smooth unanimity of curved screen compass screen surface, percent opening is low, and the sieve seam is inhomogeneous, and the separation rate of material is lower, and the sieve seam is prone to stop up.
Summary of the invention
The utility model purpose is to solve the aforementioned problems in the prior, and a kind of curved screen is provided.
The utility model is for achieving the above object; The technological means that is adopted is; A kind of curved screen; Comprise curved screen framework and grating, many said gratings tilt and are welded on the said curved screen framework to curved screen framework bottom direction uniformly, and the tangent plane of the solder joint on each grating bottom surface and the corresponding said curved screen framework is 5 and spends the angle of spending to 10.
As preferably, said grating selects for use no magnetic abrasion-proof stainless steel to process.
The utility model beneficial effect is: simple in structure; Grating tilts and is welded on the curved screen framework to curved screen framework bottom uniformly; Increased percent opening, and formed sharper side cut, strengthened cutting power material; Can obtain higher separation rate, can avoid the sieve seam to stop up again to greatest extent.
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 structural representation of conventional arched screen cloth.
Among the figure: 1, curved screen framework, 11, curved screen framework bottom, 2, grating, 21, the grating bottom surface, 3, solder joint.
The specific embodiment
A kind of embodiment as the utility model; A kind of curved screen as shown in Figure 1; Comprise curved screen framework 1 and grating 2; Many said gratings 2 tilt and are welded on the said curved screen framework 1 to curved screen framework bottom 11 directions uniformly, and the tangent plane of the solder joint 3 on each grating bottom surface 21 and the corresponding said curved screen framework 1 is 5 and spends to the angle of 10 degree.
Said grating 2 selects for use no magnetic abrasion-proof stainless steel to process, and makes the sieve seam be difficult for stopping up.
Grating 2 tilts and is welded on the curved screen framework 1 to curved screen framework bottom 11 uniformly, has increased percent opening, and has formed sharper side cut, strengthens the cutting power to material, can obtain higher separation rate, can avoid the sieve seam to stop up again to greatest extent.
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 (2)
1. curved screen; Comprise curved screen framework (1) and grating (2); It is characterized in that: many said gratings (2) tilt and are welded on the said curved screen framework (1) to curved screen framework bottom (11) direction uniformly, and the tangent plane of the solder joint (3) on each grating bottom surface (21) and the corresponding said curved screen framework (1) is 5 and spends to the angle of 10 degree.
2. curved screen according to claim 1 is characterized in that: said grating (2) selects for use no magnetic abrasion-proof stainless steel to process.
