Abstract

The utility model discloses a specific gravity stone separator, which is composed of a feed tube, a feed box, two stone separating screen bodies, an air draft cover and a vibration system. Via refining grading plates arranged in the two stone separating screen bodies, materials are separated in circulation by a first stone separating screen surface and a second stone separating screen surface, and stones in cleaned grains and grains among stones are both decreased to the lowest degree. Thus, stone separating efficiency and technological stability are enhanced. Meanwhile, one wind source and one vibration source are adopted to compact the structure of the separator and save energy.

Description

Specific gravity stone separator

The utility model relates to cereal cleaning equipment, is a kind of stone remover specifically.

Its main frame of existing stone remover has feed hopper, removes the stone sieve nest, rack support mechanism, and the longitudinal angle elevating lever is going that two vibrating motors are set on the stone sieve nest.Material drops on the crimped wire woven mess from feed hopper, the effect of vibrating motor exciting force make sieve nest directed move back and forth and the effect of from bottom to top wind-force under form automatic classification, the grain grain that is suspended in the upper strata is under deadweight and compass screen surface vibration effect, outside the downslide discharge machine, be sunken to sandstone that lower floor is close to compass screen surface the frictional resistance of compass screen surface and upwards under the inertia force effect to the operation of selected district.The grain grain that is mixed in the sandstone is gone back to the Disengagement zone by wind.Because the charging aperture flow is uncontrollable, and the uniformity of charging and poor stability cause classification bad, the stone effect is gone in influence in addition, and the stone amount that contains of grain grain exceeds standard.

The purpose of this utility model is to adopt two layers of stone remover structure, feed rate control etc., goes the stone effect to improve classification.

Be the realization the purpose of this utility model, the double-deck stone remover that provides, it comprises feed pipe and the air draught adjustable pipe that is positioned at support frame, feed box is fixed on the framework by suspended hood.Two roads go the stone sieve nest to hang over below the framework, and one end and framework fix, and the other end is fixed on the longitudinal angle elevating lever and is fixed on the stand by rubber shock absorber.Between feed pipe and the feed box, all adopt between air draught adjustable pipe and the suspended hood to be flexible coupling.Go in two roads that one crimped wire woven mess has the air uniform plate that links with it in the stone sieve nest, link with framework around compass screen surface and the air uniform plate, two roads go the airduct of stone sieve to enter the suspended hood middle part by volume adjusting apparatus to communicate with the air draught adjustable pipe.In feed pipe, be provided with automatic flow control system and vibrating motor connects.The utlity model has characteristics such as stone efficient high technology stable performance.

Fig. 1 structure chart of the present utility model.

Fig. 2 fundamental diagram of the present utility model.

Fig. 3 side view of the present utility model.

With reference to Fig. 1,3, the specific-gravity stoner structure comprises feed pipe (6) and air draught adjustable pipe (7), automatic control box (22), U type manograph (14) are fixed on the support frame (15), feed box (5) is fixed on the suspended hood (4), be distributed with observation window (8) on the suspended hood (4), hand hole (16) hand hole (17) and discharging opening (19).Screen frame (18) is fixed on framework (3) and is fixed on the support (11) through rubber shock absorber (10) by vibrational system (9) and longitudinal angle elevating lever (2).The middle part is hung two roads and is removed stone sieve nest (1) below the framework (3).Two road crimped wire woven messes (26) change angular dimension and fixation by two road crimped wire woven mess (26) longitudinal angle governor motions (12).Two roads go the stone sieve nest also to be provided with stone outlet hole (20), return sieve mouthful (21).

With reference to Fig. 2, the operation principle of specific-gravity stoner: after material enters feed pipe (6) and reaches some, by feed position automatic control box (22), the entry into service of control vibrating motor (9), produce exciting force and wind-force, wind-force enters in the suspended hood (4) by air uniform plate (25) and volume adjusting apparatus, and material enters feed box (5) back and controls its stability and uniformity by flow control board (27).The material that drops on the refining graded plate (23) forms classification for the first time under the effect of vibration force and wind-force, be that heavy sandstone mixture sinks to lower floor and contacts upwards operation with refining classification (23) plate, directly enter in the two road crimped wire woven messes (26) by adjustment doors and separate; Upper materials glides and enters one crimped wire woven mess (24) continuation separation, material on one crimped wire woven mess (24) is under the effect of vibration force and wind-force, clean grain is discharged by discharging opening (19), the stone mixture upwards runs to selected district, its China Oil and Food Import and Export Corporation's grain is gone back to the Disengagement zone by wind, the sandstone mixture enters two road crimped wire woven messes (26) and continues to separate from the isolated sandstone mixture of refining graded plate, isolated pure stone is discharged by stone outlet hole (20), and the grain mixture is sent this machine back to by time sieve mouthful (21) and handled.

Double-deck compass screen surface specific-gravity stoner has compact conformation, and volume is little, and treating capacity is big, and the feed separation circuit is long, and the separative efficiency high also can be according to the promotion angle and the inclination angle of removing the stone sieve nest of the difference change bobbing machine that contains the stone amount in the raw grain. Because the double-deck compass screen surface of this machine adopts same wind regime and vibration source, a body. Therefore energy consumption is low.
