Description

Sump automatic dredging system
Technical field
It the utility model is related to a kind of desilting equipment, more particularly to a kind of sump automatic dredging system.
Background technology
Sump is an indispensable part in Mine Drainage System, and it mainly has two effects:When water, second, heavy Form sediment.Containing impurity based on coal slime and sandstone in mineral water, into sump after precipitate.Sediment in sump needs clear in time Dig out, otherwise can reduce the dischargeable capacity of sump, when running into unexpected water burst, the water of sump, which can overflow, causes shaft station quilt The risk flooded;When sediment product becomes silted up excessive, debris can enter absorbing well, absorption well, be then drawn into water pump, the mistake of unstable wear water pump Stream unit;Water-drawing tap can be also blocked when absorbing well, absorption well mud is excessive, causes draining difficult or can not draining.Therefore, how efficiently It is to improve one of Mine Drainage System security and economy important channel that ground, which digs clearly sump,.
Traditional sump dredging method has following several:
1st, artificial Dredging method:Manually mud is dug out, loads mine car and transports.Feature is that method is simple, but worker's labor Fatigue resistance is big, speed is slow, work efficiency is low, and last pasty state mud cleaning difficulty is big, and processing is difficult.
2nd, mechanical dredging desilting method:It is standby using special digging installing, mud loading mine car is transported into sump.Feature is to drop The labor intensity of low worker, but device structure is complicated, and cleaning effect is poor, digs the standby difficulty in walking in sump of installing.
3rd, plunger dredge pump desilting method:Using special plunger dredge pump, mud dilution heel row is dealt with again to ground. Advantage is that labor intensity is low, and cleaning efficiency is high.Shortcoming has:First, ground sewage processing system need to be built;2nd, during plunger pump work Caused pulsatile impact is to drainage pipeline system well damage;3rd, main drainpipe blocking is easily caused, pipeline inner wall is hung dirt, drop Low drainage efficiency.
Above method generally existing problems with:The cleaning of pasty state mud is not thorough, and moisture is big in mud, easily pollutes ring Border.
During sump desilting, the cleaning of pasty state mud is more difficult.The reason for producing pasty state mud is mud reclaimed water Divide content too big, separated the water in mud by filter press, the less mud of moisture and the water separated are distinguished Transport and processing, cleaning that can be to pasty state mud are more thorough.It is small that this method can be used for slime content, cleaning more frequently ore deposit Well, but for the larger large-scale mine of slime content, the disposal ability of filter press can not meet to require, and filter press can only typically be located Manage particle diameter<0.5mm debris.
Utility model content
It is automatic that technical problem to be solved in the utility model is to provide a kind of sump that can efficiently clear up pasty state sludge Desilting system.
The utility model is that solve above-mentioned technical problem by the following technical programs:Sump automatic dredging system, including Mud scraper, submersible sewage pump, vibratory sieve and filter press, the mud scraper are located in sump, and the submersible sewage pump is located at the mud scraper and scraped Go out the storeroom of mud, the submersible sewage pump connects the vibratory sieve by pipeline, and the outlet of the vibratory sieve connects the press filtration Machine.
