Abstract
The utility model discloses a pulverized coal slime dehydration system, and relates to a coal preparation plant coal slime washing system. The pulverized coal slime dehydration system mainly solves the problems that in an existing pulverized coal slime dehydration system, the number of used equipment is large, the system is difficult to control, product losses are large, and coal quality is low. The pulverized coal slime dehydration system comprises a classifying screen which is respectively connected with a mixing box and a coal slime barrel. The mixing box is sequentially connected with a heavy medium cyclone, a dehydration sculping screen and a horizontal type centrifuge. The coal slime barrel is sequentially connected with a classifying cyclone, a spiral sorting machine, a pulverized clean coal barrel, a cyclone and a vertical type centrifuge. The spiral sorting machine is further connected with a high-frequency screen. The pulverized coal slime dehydration system is simple in structure and convenient to operate. Additionally, compared with the prior art, the pulverized coal slime dehydration system reduces utilization of equipment, enables the whole system to be easy to control, reduces losses of product, and improves coal quality.
Description
Technical field
The utility model relates to coal preparation plant's coal slime washing system, is specifically related to a kind of smalls mud dewatering system.
Background technology
At present, the main cyclone that adopts of spiral spoil section dehydration concentrates+the high-frequency screen dewatering process, wherein, must use pump to provide the pressure material to cyclone, and use equipment is more, and system is difficult to control; General belt feeder is through directly discarding or retrieval system with the smalls under the device cleaning clearly, the product belt of washing especially, and this just causes product loss or ature of coal problem.
Summary of the invention
The utility model is many in order to solve existing smalls mud dewatering system use equipment, the difficult control of system, and product loss and the low problem of ature of coal, and a kind of smalls mud dewatering system is provided.
The utility model is achieved through the following technical solutions:
A kind of smalls mud dewatering system, comprise classifying screen, classifying screen connects respectively mixer and coal slime bucket, wherein said mixer connects the cyclone that heavily is situated between, dehydration sculping screen, horizontal centrifuge successively, described coal slime bucket connects classifying cyclone, spiral, fine cleaned coal bucket, cyclone, vertical centrifugal machine successively, and described spiral also connects high-frequency screen.
During work, in coal preparation plant's washing process, lump coal (+13mm) adopting the dense-medium shallow-tank separator sorting, smalls (13-1.4mm) uses dual medium cyclone dressing, and smalls mud (1.4mm) uses the spiral sorting.
Wash smart last technological process: last raw coal is beaten to classifying screen, carried out desliming screening, after oversize is sent into mixer, sub-elect by the cyclone that heavily is situated between, dehydration sculping screen, horizontal centrifuge and to wash the essence end; Screenings is delivered to classifying cyclone by the coal slime bucket, and underflow sub-elects fine cleaned coal and last spoil by spiral, and fine cleaned coal becomes by cleaned coal bucket, cyclone, vertical centrifugal machine dehydration washes the essence end, and last spoil becomes the sieve end by the high-frequency screen dehydration.
The utility model is simple in structure, and is easy to operate, compared to existing technology, reduced the use of equipment, so that whole system is more easy to control, alleviated the loss of product, improved the quality of coal.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1-classifying screen, 2-mixer, 3-coal slime bucket, 4-heavily be situated between cyclone, 5-dehydration sculping screen, 6-horizontal centrifuge, 7-classifying cyclone, 8-spiral, 9-fine cleaned coal bucket, 10-cyclone, 11-vertical centrifugal machine, 12-high-frequency screen.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of smalls mud dewatering system as shown in Figure 1, comprise classifying screen 1, classifying screen 1 connects respectively mixer 2 and coal slime bucket 3, wherein said mixer 2 connects the cyclone 4 that heavily is situated between, dehydration sculping screen 5, horizontal centrifuge 6 successively, described coal slime bucket 3 connects classifying cyclone 7, spiral 8, fine cleaned coal bucket 9, cyclone 10, vertical centrifugal machine 11 successively, and described spiral 8 also connects high-frequency screen 12.
