Abstract

The utility model discloses a sandstone separator provided with an internal and external spiral screening filter screen with taper scale holes. The sandstone separator is smoother in sandstone separation, and ensures that the cleanliness of sandstone cleaned by the sandstone separator is improved and sand content of slurry at a drain outlet is reduced. The sandstone separator comprises a frame and is characterized in that a motor is arranged on the frame; a roller filter screen (3) is arranged in the frame; an internal spiral blade (1) is arranged inside the roller filter screen (3); an external spiral blade (2) is arranged outside the filter screen (3); the internal spiral blade (1), the external spiral blade (2) and the roller filter screen (3) are connected with a driving shaft of the motor respectively; filter holes (6) formed in the filter screen (3) are changed into taper holes which have small inside and large outside.

Description

Internal and external screw screening adds the sand-stone separator of tapering fish scale hole filter screen
Technical field
The utility model belongs to sand-stone separator structure field, the sand-stone separator that especially a kind of minute sandstone is more smooth and easy, internal and external screw screening that improved the cleannes of the sandstone that sand-stone separator cleans out and reduced sewage draining exit pulp-water sand content adds tapering fish scale hole filter screen.
Background technology
In the process of social develop rapidly, economize on resources, protection of the environment, maintains the concern that social sustainable development is subject to the whole society day by day.As the also fast development of commerical ready-mixed concrete that builds social infrastructure construction.In fast-developing process, the re-using of sand, stone and the zero-emission of pulp-water become the ultimate aim of manufacturing enterprise.
Sand-stone separator is the nucleus equipment of concrete recycle system, is mainly used in the sewage and the sandstone in residual concrete that clean tank car to clean separation and recycling.At present, the screen cloth of conventional sand-stone separator is the slotted hole of parallel yi word pattern, by adding one group of pinch roller, the stone being stuck on filter screen is compressed into, and guarantees the area that shakes out of filter screen.The screen cloth of design has two drawbacks like this, one, and the slotted hole of yi word pattern, in the rotation process of screen cloth, is unfavorable for the cleaning of stone.It is changed into chevron shaped fish scale hole, and water will enter the inside of screen cloth along the direction of screen cloth rotation from fish scale hole, stone is cleaned, and the stone cleannes that come out are like this high.Its two, pinch roller assembly belongs to consumable accessory, have more than is neededly must change for a long time, will cause stone and the cement mortar that screen surface is blocked to seal if do not changed, just cannot separated stone and sand.Therefore the problem existing is: (1) has some setbacks while making sand-stone separator divide sandstone, easily stops up; (2) cleannes of the sandstone that sand-stone separator cleans out are low; (3) sand content of sand-stone separator sewage draining exit plasma discharge water is high.
Utility model content
The purpose of this utility model is to provide the sand-stone separator that a kind of minute sandstone is more smooth and easy, internal and external screw screening that improved the cleannes of the sandstone that sand-stone separator cleans out and reduced sewage draining exit pulp-water sand content adds tapering fish scale hole filter screen:
The technical solution of the utility model is: internal and external screw screening adds the sand-stone separator of tapering fish scale hole filter screen, comprise frame, it is characterized in that being provided with motor in frame, in frame, be provided with cylinder filter screen (3), in the inside of described cylinder filter screen (3), be provided with internal helical blades (1), outer setting at filter screen (3) has external spiral blade (2), and described internal helical blades (1), external spiral blade (2) and cylinder filter screen (3) are connected with motor driving shaft respectively; The upper filter bores (6) arranging of filter screen (3) changes inner small and outside big tapered hole into.
In frame, near the position of end, be provided with overflow groove (4), in the arranged outside of overflow groove (4), have stone outlet hole (5).
Effect of the present invention is: internal and external screw screening adds the sand-stone separator of tapering fish scale hole filter screen, in frame, be provided with motor, in frame, be provided with cylinder filter screen, inside at described cylinder filter screen is provided with internal helical blades, outer setting at filter screen has external spiral blade, and described internal helical blades, external spiral blade and cylinder filter screen are connected with motor driving shaft respectively; The filter bores arranging on filter screen changes inner small and outside big tapered hole into.
The utlity model has following features: the design of the filter screen tapering fish scale hole of (1) sand-stone separator, the problem of well having avoided filter screen to stop up, when making the rotary screen mesh screen of sand-stone separator inside divide sandstone, more smooth and easy, be difficult for stopping up; (2) cleannes of the sandstone that sand-stone separator cleans out have been improved; (3) greatly reduce the sand content that sand-stone separator sewage draining exit ejects pulp-water.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of screen cloth in Fig. 1;
Fig. 3 is I place enlarged drawing in Fig. 2;
Fig. 4 be in Fig. 3 A-A to profile.
The specific embodiment
In Fig. 1, internal and external screw screening adds the sand-stone separator of tapering fish scale hole filter screen, comprise frame, in frame, be provided with motor, in frame, be provided with cylinder filter screen 3, in the inside of described cylinder filter screen 3, be provided with internal helical blades 1, in the outer setting of filter screen 3, have external spiral blade 2, described internal helical blades 1, external spiral blade 2 and cylinder filter screen 3 are connected with motor driving shaft respectively; The filter bores 6 arranging on filter screen 3 changes inner small and outside big tapered hole (referring to Fig. 2, Fig. 3 and Fig. 4) into.In frame, near the position of end, be provided with overflow groove 4, in the arranged outside of overflow groove 4, have stone outlet hole 5.
Operation principle of the present utility model is: the effect of the filter screen of sand-stone separator is diameter to be less than to the sand of 6mm, small opening by screen cloth is separated, and diameter is greater than the stone of 6mm, by the helical blade of cylinder screen cloth inside, enter stone outlet hole, separate, and the sand spilling, the helical blade by cylinder screen cloth outside and carry sand hopper, has pulled all sands washings of separating out.
After the hole of filter screen is changed into inner small and outside big tapered hole, seldom there is stone can be stuck on screen cloth, so just do not need to have filled pinch roller assembly, even if there is handstone to be seldom stuck in hole, also can to it, process by the high pressure spray shower pipe of automatic control, make its Automatic-falling.
The Position Design of sand-stone separator stone outlet hole, overflow groove, makes sand-stone separator bottom 1/3rd full water all the time, because overflow groove design is in the end of sand-stone separator, like this, overflows the pulp-water coming and is not easy to take out of sand.
