Abstract
The utility model discloses a sieve bend with a double-layer screen. The sieve bend with the double-layer screen comprises a sieve framework and the screen fixedly arranged on the sieve framework, wherein the screen is of a combined structure, and consists of a large-screen cut screen and a small-screen cut screen; the large-screen cut screen and the small-screen cut screen are vertically arranged; the large-screen cut screen is arranged above the small-screen cut screen, and the large-screen cut screen and the small-screen cut screen are respectively and fixedly arranged on the sieve framework. According to the sieve bend, by skillfully utilizing a space structure, supplied materials are layered, and therefore, the sieving area is increased, the process effect is improved, and the service life of the screen is prolonged.
Description
Technical field
The utility model relates to a kind of sieve bend, particularly relates to a kind of for improving sieve bend disposal ability and extending the screen cloth Double-layer screen sieve bend in service life.
Background technology
In dense-medium separation industry, de-mediated sieve bend is very important equipment in dense-medium separation system, and it carries out pre-de-mediated to the pan feeding of de-mediated linear vibrating screen, and Jie that lets out of sieve bend measures the 50-70% that reaches systemic circulation amount, and effect reaches more than 80% preferably.The result of use of arc sieve net, directly affects the economic benefit of coal preparation plant.Curved screen runs and is situated between, and has a strong impact on the production cost of coal preparation plant.The screen cloth of the sieve bend of current whole industry is single layer structure, and screen cloth is short service life, frequently changes not only cost rising of screen cloth, and time-consuming, effort.
Summary of the invention
The purpose of the present utility model is short service life for background technology single-deck screen web frame, frequent replacing screen cloth cost is high, time-consuming, the deficiency of effort, and a kind of screen clothes that two kinds of different sieve seams are installed on screen frame are provided, increase the processing area of sieve bend with two kinds of screen clothes
Improve de-medium effectiveness, extend the screen cloth Double-layer screen sieve bend in service life.
Realize above-mentioned purpose by the following technical solutions:
A kind of Double-layer screen sieve bend, comprises screen frame, is fixed on the screen cloth on screen frame, described screen cloth is fabricated structure, is made up of shaker screen slotted screen and little sieve slotted screen, and shaker screen slotted screen and little sieve slotted screen are arranged up and down, shaker screen slotted screen is upper, little sieve slotted screen under, be separately fixed on screen frame.
Adopt technique scheme, shaker screen slotted screen is positioned at top, large granular materials is falling into landing rapidly after the screen cloth of upper strata, little sieve slotted screen is positioned at bottom, pass through on little sieve slotted screen between the material between two-layer screen cloth partition size, screenings is discharged by screen frame, and above-mentioned two-layer screen cloth is all fixed on screen frame.Compared with prior art, the utility model compact conformation, save space, be convenient to technology arrangement.The processing area that is equivalent to increase sieve bend, has improved de-medium effectiveness, has extended again screen cloth service life.There is significant economic benefit and social benefit.
As preferred version:
The sieve seam of described shaker screen slotted screen is 3～10mm.
The sieve seam of described little sieve slotted screen is 0.5～1.5mm.
This sieve bend has utilized space structure cleverly, and by supplied materials layering, the sieving area having increased, has improved technological effect.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Mark in figure: screen frame 1, large slotted screen 2, crack screen cloth 3, sieve bottom outlet 4.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
The utility model design philosophy is: the sieve bend that a kind of Double-layer screen structure is provided, the structure of this sieve bend is shown in Fig. 1, Double-layer screen is that the large slotted screen 2 of 3～10mm and sieve seam are that 0.5～1.5mm crack screen cloth 3 forms by sieving seam, and large slotted screen 2 and crack screen cloth 3 are commercially available prod.Slotted screen 2 is arranged up and down with crack screen cloth 3 greatly, and large slotted screen 2 is positioned at the top of crack screen cloth 3, is fixed by bolts to respectively on screen frame 1.
The course of work of the present utility model:
When sieve bend supplied materials, shaker screen slotted screen 2 is positioned at top, large granular materials is by the landing fast above of large slotted screen 2, little sieve slotted screen 3 is positioned at bottom, material between large slotted screen 2 and crack screen cloth 3 partition sizes passes through on crack screen cloth 3, the granularity requirements that ensures screenings, the screenings of crack screen cloth 3 is discharged by screen frame outlet at bottom 4.
Claims (1)
