The movable sieve jig is characterized in that, via the movable sieve mechanism (5) under drive of the hydraulic oil cylinder (6), the movable sieve jig performs up and down reciprocating motion around the pin shaft (13) and in water, material bed layers on the sieve plate (3) are delaminated according to density after periodic lossening, substances through delaminating are lifted by the lifting wheel and discharged from each chute; the beneficial effects of the movable sieve jig are: simple process, high sorting efficiency, convenient installation and maintenance, good reliability, and wide suitable scope.
Description
Technical field
The utility model relates to a kind of coal washing, cleaning unit, is specially a kind of movable-sieve jig that is used for coal washing.
Background technology
Coal separation is rationally to utilize coal resources, protection environment most economical and otherwise effective technique.Processing charges is low, is that coal deep processing, clean coal are produced requisite basis and key, and it can optimize the coal product structure on the one hand, increases operation rate, and is front-seat except that a large amount of spoils in transportation on the other hand, practices thrift transport power, reduced the coal cost.Thus, washing appliance has become the capital equipment of coal production, and its productivity effect index counts for much to programing in coal preparation.In numerous ore dressing field, jigging machine is in occupation of consequence very, and jigging machine is a kind of gravity beneficiation equipment, utilizes the medium of water as ore dressing, carries out sorting according to the proportion of mineral.Along with the raising of coal mining mechanization degree and the continuous development of science and technology; Plunger type washbox, diaphragm jig, air pulsating jig, hydraulic pulse jigging machine, movable-sieve jig etc. have appearred in jigging machine also corresponding variation and the development that the property changed occurs in succession.But all there is selected little, the problem such as particle size fraction is narrow, water consumption is big of reaching the standard grade in present jigging machine; Simultaneously because the raising of mining machinesization at present increases the spoil amount and the coal amount of sneaking in the raw coal; And the discharge refuse mode that most of movable-sieve jig adopted is mainly jigging discharge refuse, heavily be situated between discharge refuse, the broken machine discharge refuse that selects of selectivity; Its system complex, investment are greatly, the scope of application is narrow, noise is big, can not adapt to the requirement of new situations.
Summary of the invention
The purpose of the utility model is to provide a kind of selected movable-sieve jig that is used for coal washing big, that auxiliary equipment is few, water consumption is little of reaching the standard grade.
A kind of movable-sieve jig that is used for coal washing of the utility model is made up of discharge refuse wheel 1, flashboard 2, sieve plate 3, cell body 4, screen plate moving mechanism 5, hydraulic jack 6, buoy 7, downflow weir 8, lifting wheel, cleaned coal chute 11, slate chute 12, bearing pin 13, driving-chain 14, discharge gate 15, slope 16; It is characterized in that: described cell body 4 is the casing that a two bottom sides is respectively equipped with slope 16; The intersection on slope 16 is provided with discharge gate 15; One end of cell body 4 is provided with lifting wheel, and the other end is provided with screen plate moving mechanism 5; Described lifting wheel is divided into lifting wheel leading portion 9 and lifting wheel back segment 10, and its upper end is respectively equipped with slate chute 12 and cleaned coal chute 11; The middle part of said screen plate moving mechanism 5 is provided with downflow weir 8 and flashboard 2, and described flashboard 2 is fixed on the below of downflow weir 8; Screen plate moving mechanism 5 bottoms are provided with sieve plate 3 and driving-chain 14, and described sieve plate 3 is connected through discharge refuse wheel 1 with driving-chain 14, and the other end of described driving-chain 14 is fixed on the lifting wheel through bearing pin 13; Described hydraulic jack 6 is positioned at a side of screen plate moving mechanism 5 and is installed on the cell body; An opposite side and an end that described buoy is positioned at screen plate moving mechanism 5 are positioned at cell body 4.
A kind of principle that is used for the movable-sieve jig of coal washing of the utility model is that the screen plate moving mechanism 5 that is in water is under the driving of hydraulic jack 6; In aqueous medium, do upper and lower reciprocating motion around bearing pin 13; It is periodically loose that material bed on sieve plate 3 is obtained, and through behind the jigging repeatedly, realizes that this material bed is by density stratification; The different densities material of layering is discharged through cleaned coal chute 11, slate chute 12 and discharge gate 15 respectively the most, realizes optimizing the purpose of coal separation.Its beneficial effect is, technology is simple, the efficiency of separation is high, convenient for installation and maintenance, good reliability, the scope of application is wide and do not produce leakage phenomenon.
Description of drawings
Accompanying drawing is a kind of structural representation that is used for the movable-sieve jig of coal washing
In the accompanying drawing: discharge refuse wheel 1, flashboard 2, sieve plate 3, cell body 4, screen plate moving mechanism 5, hydraulic jack 6, buoy 7, downflow weir 8, lifting wheel leading portion 9, lifting wheel back segment 10, cleaned coal chute 11, slate chute 12, bearing pin 13, driving-chain 14, discharge gate 15, slope 16
The specific embodiment
The utility model relates to the industrial machinery technical field, is specially a kind of movable-sieve jig that is used for coal washing, shown in accompanying drawing; Form by discharge refuse wheel 1, flashboard 2, sieve plate 3, cell body 4, screen plate moving mechanism 5, hydraulic jack 6, buoy 7, downflow weir 8, lifting wheel, cleaned coal chute 11, slate chute 12, bearing pin 13, driving-chain 14; Be specially: in cell body 4, be full of the water of certain altitude, the screen plate moving mechanism 5 that is in water pumps around bearing pin 13 under the driving of hydraulic jack 6; Feed coal feeds screen plate moving mechanism 5 backs and on sieve plate 3, forms certain thickness bed; Screen plate moving mechanism 5 aqueous medium when rising moves downward with respect to material, and screen plate moving mechanism 5 is when downward, and aqueous medium forms the upwelling with respect to screen plate moving mechanism 5; Material is made hindered settling in aqueous medium, realize by density stratification.Light product after the layering is crossed downflow weir 8, falls into the rear end 10 of lifting wheel, is mentioned by lifting wheel and pours into outside the slate chute 12 lower floors discharge body; Heavy product is discharged by discharge refuse wheel 1, falls into the front end 9 of lifting wheel, is mentioned by lifting wheel and pours into outside the slate chute 12 lower floors discharge body; Sieving fine thoroughly falls on the slope 16 of cell body 4 bottoms and is discharged outside the bodies by discharge gate 15.At work, during shatter value by the kinetic characteristic decision of screen plate moving mechanism 5.
