Description

A kind of Separator of heavy medium shallow slot

Technical field

The utility model relates to coal preparation plant's field of mechanical technique more particularly to a kind of Separator of heavy medium shallow slot.

Background technique

Coal is the main energy sources in China, 70% or more is accounted in non-renewable energy consumption, in quite long one period Interior, coal will not change as the status of main energy sources.For thermal coal selective ratio in 2010 less than 800,000,000 tons, selective ratio is about 35%, With the development of national economy, the increasingly improvement of people's lives, scientific and technical is constantly progressive, and energy-saving and emission-reduction are carried forward vigorously, To the clean and effective of coal using being increasingly taken seriously, " the clean coal technology plan " that China is carrying out be then meet the tendency of and It is raw.Coal preparation is undoubtedly the basis of clean coal technology, he can fundamentally improve and improve Coal Quality, drop Pollution brought by low coal burning, reduces energy consumption, improves transport power, increases the performance of enterprises, and current driving force coal selective ratio is about 14.7 hundred million tons, selective ratio has reached 53.5%.

Heavy media coal separation method is tested since mid-term the 1950s in China.Since heavy media coal separation is with many excellent Point, especially its sharpness of separation height, selected particle size range are again wide, so its application range in coal preparation technique is very wide It is general.In recent years, with the further development of coal market economy, the requirement of environment and user to Coal Quality is higher and higher, essence The superiority of degree sink float is more and more obvious, and most of newly-built or reconstruction coal preparation plant all uses part dense medium or full weight Jie's stream Journey.So far, the selected specific gravity of the heavy media coal separation method in China will have reached 70% or more.

It is sorted at present using dense media shallow slot using coal preparation plant's sorting lump coal of dense-medium separation method, the equipment point Select accuracy height.The working principle of Separator of heavy medium shallow slot are as follows: suspension feeds sorting machine by two positions in sorting machine Groove body in, fed from lower part be rise medium flow field, entered in slot by cloth flowing plate with holes, it can be made to be uniformly dispersed, Rise medium flow field effect be to maintain effect suspension stabilization, uniformly, while play the role of disperse pan feeding.Feed from side is level Medium flow field can be made horizontal media stream overall with, be uniformly entered in the groove body of sorting machine by the counterattack and limitation of cloth hopper. The density of suspending liquid that the effect of horizontal media stream is to maintain groove body top is stablized, and the level from feeding inlet to discharge port is formed simultaneously Medium flow field starts shipment upper floating cleaned coal defeated effect.After feed coal feeds sorting groove, all soaked under the action of controllable register Enter in suspension.Start to be layered under the action of buoyancy at this time.The low-density object such as cleaned coal floats on upper layer, the high density such as spoil Object sinks to groove body bottom.During sinking, the low-density object mixed with spoil is filled due to rising the effect of medium flow field After dispersion, continue to float.Under the action of horizontal media stream, float on the low-density object on suspension top by discharge port discharge at For head coal product.Under the action of scraper plate, the high density object for sinking to slot bottom becomes spoil product by head chute discharge, thus complete At the assorting room of raw coal.

The suitable particle size range of Separator of heavy medium shallow slot sorting is 13mm~200mm, but with 8 meters~9 meters of underground The appearance of high working face, coarse coal is more in raw coal, and yield is higher, in actual assorting room, due to large particle coal, especially The close and coal cinder more than 200mm is difficult to overflow by overflow part under the action of horizontal media stream, gets lodged in overflow often In portion, the separating effect of shallow slot is seriously affected, causes spoil coal carrying rate high, while overflow part blocking causes dense media shallow slot to handle Amount reduces, and failure increases, and prolonged overflow is frequent at scraper plate chain rupture.In order to reduce the stifled influence of overflow part, guarantee that shallow slot overflows Stream portion is unimpeded, and a post is specially arranged at shallow slot overflow part, periodically carries out unimpeded with iron hook.It is periodically used by live post work Iron hook carries out unimpeded to discharge port, not only increases the staff of coal preparation plant, increases cost of labor, and the labour of post work Intensity, frequent hooked scarf bring larger security risk to the personal safety of post work.
