Abstract
The purpose of this utility model is to provide a kind of high-precision vibrating screen, can accurately control screen size, has higher screening efficiency, and has advantages of that the compass screen surface life-span is long, sieve nest weight is less, it is less to consume electric energy.The utility model is exactly that double-deck different compass screen surfaces is set in sieve nest, and upper compass screen surface is elasticity bar screen surface, and lower floor's compass screen surface is broach compass screen surface.Utilize efficient elasticity bar screen surface that material is carried out to just classification fast, then lower floor's broach compass screen surface carries out high-precision classification.Under identical volume and power, can greatly improve efficiency and the precision of screening.Drapery panel is not the plane of prior art, but a raised structures is arranged at axis bottom therein, and it is large that its height and width become downwards gradually.Material is separated to both sides, make thinner fast, improve the utilization rate of top compass screen surface.
Description
Technical field
The utility model relates to vibratory sieve, particularly relates to a kind of high-precision vibrating screen.
Background technology
Industrial production widely applies vibratory sieve to carry out the classification of various materials, all generally to drive sieve nest to vibrate by vibrator, compass screen surface is installed in sieve nest, material is by motion from top to bottom on compass screen surface, the material that is greater than sieve aperture moves to compass screen surface front end exit always and falls into the transporter of feed bin or sealing-tape machine one class, and the material that is less than compass screen surface is fallen the transporter of another one feed bin or another one sealing-tape machine one class through compass screen surface.Varigrained material completes classification thus.Main compass screen surface has three kinds at present: plate hole formula compass screen surface, broach compass screen surface, elasticity rod formula compass screen surface.Plate hole formula compass screen surface has advantages of that precision is high and the life-span is long, but easy plug-hole and the low shortcoming of screening efficiency; Broach compass screen surface is slightly higher than plate hole formula compass screen surface efficiency, be not easy the advantage of plug-hole, but the compass screen surface life-span is short, and screening efficiency is lower than elasticity bar screen surface; Flexible rod bar grizzl(e)y mask has the advantage that screening efficiency is very high, be difficult for plug-hole, but its precision is the poorest, has the more material that is greater than gradational boundary to fall into screenings through compass screen surface.
In order to improve screening efficiency in the confined space, occurred a lot of double-deck screen shale shakers, but its upper and lower two-layer compass screen surface is same compass screen surface, effect is general.Apply comparatively limited.
Summary of the invention
The purpose of this utility model is to provide a kind of screening efficiency high, simultaneously precision very high vibratory sieve again.And have advantages of that the compass screen surface life-span is long, sieve nest weight is less, it is less to consume electric energy.
The cardinal principle of this utility model is exactly that double-deck different compass screen surfaces is set in sieve nest, and upper compass screen surface is elasticity bar screen surface, and lower floor's compass screen surface is broach compass screen surface.Utilize efficient elasticity bar screen surface that material is carried out to just classification fast, then lower floor's broach compass screen surface carries out high-precision classification.Under identical volume and power, can greatly improve efficiency and the precision of screening.
In order to realize above-mentioned object, a kind of scheme of the present utility model is:. a kind of high-precision vibrating screen, mainly includes sieve nest 1, exciting device 3 and damping supporting device 5.Exciting device 3 can be any type of device that can produce exciting force, is arranged on sieve nest 1.Sieve nest 1 is arranged on damping supporting device 5.Drapery panel 6 is arranged on charging aperture place.Upper strata compass screen surface 2 and lower floor's compass screen surface compass screen surface 4 are arranged on sieve nest inside, and upper strata compass screen surface 2 is bar screen surface, and lower floor's compass screen surface 4 is broach compass screen surface.
Further, described described drapery panel 6 is not the plane of prior art, but a raised structures is arranged at axis bottom therein, and it is large that its height and width become downwards gradually.Its effect is: the material flow to be sieved that charging aperture gets off concentrates on axis portion on drapery panel top, causes compass screen surface top utilization rate not high, increases after improved projection, and material is separated to both sides, makes thinner fast, improves the utilization rate of top compass screen surface.

Detailed description of the invention
As shown in Figure 1, a kind of scheme of the present utility model is:. a kind of high-precision vibrating screen, mainly includes exciting device and the damping supporting device of sieve nest, driven by motor eccentric block.Exciting device is arranged on sieve nest.Sieve nest is arranged on damping supporting device.Drapery panel is arranged on charging aperture place.Upper strata compass screen surface and lower floor's compass screen surface compass screen surface are arranged on sieve nest inside, and upper strata compass screen surface is bar screen surface, and lower floor's compass screen surface is broach compass screen surface.
Drapery panel is to have a raised structures at middle part, and it is large that its height and width become downwards gradually.
Disclosed technology is only good embodiment of the present utility model above; can not limit interest field of the present utility model with this example; any equivalence of doing according to the utility model claim changes; for example change mode, sieve nest shape, support pattern, sieve plate installing structure of exciting device etc., still belong to protection domain of the present utility model.
