Abstract
The utility model provides a vibrating screen for coal dressing for in the coal picker that the shale shaker slope set up, filter clean coal, characterized by in the follow raw coal: set up the delay device on the shale shaker, guarantee that the raw coal is detained on the shale shaker for a long time to fully filter the raw coal, this vibrating screen for coal dressing, the coal effect that not only stagnates is strong, can make the raw coal carry out abundant screening on the shale shaker and distinguish, and degree of automation is high in addition, and some coal picker cooperations of easily cooccurrencing only need can make the coal picker last efficient work through control stoking frequency and electric putter's flexible frequency, are convenient for adapt to the development of coal dressing modernization, reduce workman's work burden.
Description
Technical field
This utility model relates to technical field of coal mine equipment, particularly a kind of coal separation vibrosieve.
Background technology
Coal separation, also referred to as coal washing, sub-elects the process meeting the cleaned coal that user quality requires from raw coal.Ash, sulphur content all be there are certain requirements by coal for coking, it is necessary to use with the cleaned coal through washing.The petrofacies composition of coal and the quantity of minerals in coal, kind, character and distribution, be all the factor of the washability affecting coal.For the complexity of raw coal washability, the technique that coal preparation plant commonly uses has jigging, dense medium cyclone, dense-medium shallow-tank, vibro-assisted jigging, flotation etc..Other coal preparation method also has selecting crude drugs with winnower, spiral separating etc..
But, existing coal picker is when coal separation, due to raw coal directly from landing vibrosieve, holdup time is short, fully it cannot be selected screening, so could thoroughly distinguishing through multipass screening possibly with a collection of raw coal, thus causing, coal preparation technique process cost is high, efficiency is low, increase asking of workman's work burden.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of coal separation vibrosieve, it is possible to effectively increase the raw coal holdup time on the vibrating, raw coal screens differentiation fully, thus reducing coal separation cost, improves coal separation efficiency, reduces workman and works burden.
In order to realize solving the purpose of above-mentioned technical problem, this utility model adopts the technical scheme that
A kind of coal separation vibrosieve of the present utility model, for, in the coal picker that vibrosieve is obliquely installed, screening cleaned coal, it is characterized in that: arrange arresting device on the vibrating, it is ensured that raw coal is stranded in vibrosieve for a long time, thus raw coal is fully screened from raw coal；
Described arresting device includes framework, suitable shelves, crosspiece, electric pushrod and connecting plate；Along shelves with crosspiece is orthogonal is arranged in framework, framework region is divided into multiple Zhi Mei district；Being connected along shelves and framework are fixing, crosspiece is through frame facet and can extract out from framework；Connecting plate is positioned at outside framework, is connected with the prominent frame part of each crosspiece；Electric pushrod is vertically set on framework lateral surface, and its piston rod is fixing with connecting plate to be connected；Electric pushrod can drive connecting plate to move by piston rod, thus driving crosspiece extract out from frame facet or insert；The stroke of electric pushrod is equal with the width of framework；Arresting device is arranged on above vibrosieve, and it is connected by framework and vibrosieve are fixing.
Concrete: the electric pushrod in described arresting device can substitute with hydraulic cylinder or cylinder.
Concrete: being provided with location sheath with transverse slat joint outside described framework, transverse slat inserts in framework after the sheath of location.Arranging location sheath is to make transverse slat when extracting out from framework with electric pushrod, will not rock or come off.
Using method: during use, transporter is utilized to be trickled down by raw coal in the Zhi Mei district of arresting device, start coal picker and make shaker vibration coal separation, when, after shaker vibration a period of time, starting electric pushrod, then the piston rod of electric pushrod stretches out and drives crosspiece to extract out from the side of arresting device, make the raw coal block in raw coal along vibrosieve landing to the least significant end of vibrosieve, and then outside discharge vibrosieve, then make the piston rod of electric pushrod shrink and drive crosspiece reduction, then carry out next ripple raw coal screening；Utilizing this vibrosieve, in practical operation, the stretching frequency that only need to control stoking frequency and electric pushrod can make this coal picker continue to work efficiently.
These technical schemes, the technical scheme including the technical scheme improved and improvement further can also combine mutually or combine, thus reaching superior technique effect.
By adopting technique scheme, this utility model has following beneficial effect:
A kind of coal separation vibrosieve of the present utility model, not only stagnant coal effect is strong, raw coal can be made to screen differentiation on the vibrating fully, and automaticity is high, be prone to compared with coal picker coordinate, only coal picker need to can be made to continue to work efficiently by the stretching frequency of control stoking frequency and electric pushrod, it is simple to adapt to the modern development of coal separation, reduce the work burden of workman.
