Abstract

The invention discloses a coal slime water solid-liquid separator and is characterized in that: the coal slime water solid-liquid separator includes a frame which is provided with drive rollers and corresponding driven rollers layer by layer, the drive roller and the driven roller at each layer are wound with filter screens which are in butt joint, the number of meshes of the filter screens is gradually reduced from the top layer to the bottom layer, and the drive rollers are dragged by a speed adjustable motor. When in work, solid particulate matter is gradually filtered layer by layer and falls from one side of the rotation advancing direction to be collected, the sewage which is filtered layer by layer and does not contain particulate matter flows away from under the screen and is recycled. The coal slime water solid-liquid separator of the invention has the advantages that coal slime water can be filtered by the device in time, no sedimentation tank is needed for precipitation, the occupy space is small, and the device has simple structure; generally, the filtering requirements can be met by arranging three rotating filter screens.

Description

Solid-liquid separator for slime water

Technical field

The application relates to the equipment of solid-liquid separating substances.

Background technology

With the enterprise of coal, in the coal washing process, produce a large amount of black waters at some,, mostly handle with sedimentation basin in order to isolate solid matter as raw material or fuel.General sedimentation basin floor space is bigger, and the processing time is longer, waste land resource.

Summary of the invention

The application is the deficiency that overcomes the precipitation method, provides a kind of floor space little solid-liquid separator for slime water.

For achieving the above object, the application's structure is: comprise a frame, the frame higher slice is furnished with drive roll and corresponding driven roll, is wound with the filter screen of butt joint on every layer of drive roll and the driven roll, the order number of filter screen reduces from top to bottom successively, and drive roll is dragged by buncher.

Described filter screen preferably adopts stainless steel filtering net.

During work, solid particulate matter is progressively filtered layer by layer, and falls to concentrating from rotating direction of advance one side, and the sewage that does not contain particle through filtering layer by layer recycles from off the net flowing away.

The application's good effect is: 1, black water can obtain timely filtration treatment by this equipment, and without the sedimentation basin precipitation, floor space is little; 2, simple in equipment is generally established three layers of rotation filter screen and can be satisfied the filtration requirement.

Description of drawings

Fig. 1 is the application's a schematic diagram.

Marginal data: 1-driven roll, 2-filter screen, 3-coal water pipe, 4-drive roll, 5-belt pulley, 6-V-belt, 7-buncher, 8-water leg, 9-spillplate, 10-frame.

The specific embodiment

As shown in Figure 1, the application's structure is: comprise a frame 10, frame 10 higher slices are furnished with drive roll 4 and corresponding driven roll 1, are wound with the filter screen 2 of butt joint on every layer of drive roll 4 and the driven roll 1, the order number of filter screen 2 reduces from top to bottom successively, and drive roll 4 is dragged by buncher 7.Belt pulley 5 is installed, by the transmission of V-belt 6 realizations with buncher 7 on drive roll 4.

In addition, be provided with spillplate 9, prevent that solid-liquid from mixing in the front lower place of driven roll 1 one sides.

During use, coal water pipe 3 is arranged in drive roll 4 tops, and the black water that leaches flows in the water leg 8 that is arranged on below the frame 10 by filter screen 2, concentrates at last to flow away.

Claims

1, a kind of solid-liquid separator for slime water is characterized in that, it comprises a frame, the frame higher slice is furnished with drive roll and corresponding driven roll, be wound with the filter screen of butt joint on every layer of drive roll and the driven roll, the order number of filter screen reduces from top to bottom successively, and drive roll is dragged by buncher.

2, solid-liquid separator for slime water as claimed in claim 1 is characterized in that, is provided with spillplate (9) in the front lower place of driven roll (1) one side.
