Abstract
The utility model belongs to the technical field of solid-liquid separation, and particularly discloses a solid-liquid separation system. The solid-liquid separation system comprises a dewatering screen and a deep-cone thickener, wherein an underflow port of the deep-cone thickener is connected with the dewatering screen via a hose pump, a filtrate port of the dewatering screen is in return connection to a feeding port of the deep-cone thickener, and an overflow port of the deep-cone thickener is connected with a circulating water return pool. The solid-liquid separation system disclosed by the utility model adopts the deep-cone thickener which is separated from the dewatering screen, so that needed power is small, and the cost is low; and after the thickening and dehydration of the deep-cone thickener, a filter cake with water content of not more than 15wt% and overflow water with solid content of not more than 200 mg/l are obtained, the filter cake can be directly piled up in a dry method, the overflow water does not need to be dehydrated, clarified and precipitated by a press filter again, automatically flows to the circulating water return pool and can be directly recycled as water of productive use, and the process flow of solid-liquid separation is simplified.
Description
Technical field
The utility model belongs to the solid-liquid separation technique field, is specifically related to a kind of solid-liquid separation system.
Background technology
At present, the dewatering screen dewatering process is usually concentrated with cyclone with ore pulp (solid weight concentration 25～30%) first, and cyclone underflow (solid weight concentration 45～50%) enters the dewatering screen dehydration, and oversize is the filter cake dry piling; It is concentrated that the dewatering screen screenings is that filtrate is returned cyclone circulation, the filter press filter-press dehydration is adopted in the cyclone overflow, the filter press filtrate water just can be returned production cycle and use after the clarification precipitation, Main Problems is that cyclone and dewatering screen are typically designed to one, cyclone feed pump equipment dynamic is large, cost is high, and technological process is complicated.
The utility model content
At the bottom of the purpose of this utility model is to provide a kind of cost, the simple solid-liquid separation system of technological process.
For achieving the above object, the technical scheme taked of the utility model is as follows:
A kind of solid-liquid separation system, comprise dewatering screen, described solid-liquid separation system also includes deep cone thickener, the underflow opening of deep cone thickener is connected with dewatering screen by peristaltic pump, the filtrate port of dewatering screen is returned the charging aperture (filtrate is from flowing to deep cone thickener) that is connected to deep cone thickener, and the overfall of deep cone thickener is connected with and loops back the pond.
Preferably, the filtrate port of dewatering screen is returned the charging aperture that is connected to deep cone thickener by reservoir, slag stock pump successively.Like this, the filtrate behind the dewatering screen can be delivered to deep cone thickener by means of the slag stock pump and circulates and to process.
The utility model adopts deep cone thickener, and deep cone thickener and dewatering screen minute are arranged, and required drive is little, and cost is low; After the deep cone thickener thickening, obtain the filter cake of moisture content≤15wt% and the overflow water of solid content≤200mg/l, filter cake is dry piling directly, overflow water need not again through filter press dehydration and clarification precipitation, loop back the pond by flowing automatically to, can directly recycle for industrial water, simplify the solid-liquid separation process flow process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of solid-liquid separation system, comprise dewatering screen 3, described solid-liquid separation system also includes deep cone thickener 1, the underflow opening of deep cone thickener 1 is connected with dewatering screen 3 by peristaltic pump 2, the filtrate port of dewatering screen 3 is returned the charging aperture that is connected to deep cone thickener 1 by reservoir 4, slag stock pump 5 successively, and the overfall of deep cone thickener 1 is connected with and loops back pond 6.
Running: ore pulp A(solid weight concentration 5～40%) be transported to deep cone thickener 1 with the slag stock pump, through deep cone thickener 1 thickening, concentrated underflow ore pulp B(solid weight concentration 60～70%) be transported to dewatering screen 3 with peristaltic pump 2, dewatering screen 3 adopts high-frequency, high oscillation intensity dehydration, oversize is filter cake D(moisture content≤15%), filter cake D directly dry piling to tailings stack, screenings is that filtrate water is delivered to deep cone thickener 1 through reservoir 4 usefulness slag stock pumps 5, (solid content≤200mg/l) flows automatically to and loops back pond 6 deep cone thickener 1 overflow water C, and overflow water C can recycle for industrial water.
