Abstract
An adjustable power reversing device of a movable sieve jig belongs to the technical field of coal washing equipment and aims to solve the problems, such as low probability of adjustment to quick return motion of the movable sieve and poor separating effect, in the prior mechanical movable sieve jig. The utility model adopts the technical scheme that the adjustable power reversing device comprises a power offset crank disc, a movable sieve offset crank dick, a shaft and a bolt; a power transmission component of a motor is connected with the power offset crank disc; the movable sieve offset crank disc is connected with a movable sieve body; the big end of the power offset crank disc shares the same shaft with the big end of the movable sieve offset crank disc, and crank disc surfaces of two offset crank discs are connected through a flange. By adjusting a connecting bolt of the flange for connecting the offset crack discs, the utility model enables an included angle between the offset crank discs to be adjusted, thereby adjusting the sieve body to output ideal motion curves and serve perfect quick-return effect and adjusting the quick-return property according to the coal quality of the field. Furthermore, the utility model has the advantages of simple structure, convenient operation and low operating failure rate.
Description
Technical field
The utility model relates to a kind of actuating unit of mechanical type movable-sieve jig, belongs to the wash coaling equipment technical field
Background technology
Movable-sieve jig is that a kind of direct outer power driving sieve nest moves up and down in aqueous medium, causes material periodically loose, realizes the screening installation by density stratification, is widely used in the ideal equipment of piece raw coal discharge refuse and steam coal separation.Movable-sieve jig divides fluid pressure type to drive and mechanical type drives two kinds, the driving force of hydraulic pressure movable-sieve jig is provided by hydraulic system, good separation effect, and the hydraulic system adjusting range is wide, easy to operate, but hydraulic-driven part cost height, frequent speed change transformation work are to the requirement harshness of Hydraulic Elements, and diagnosis when breaking down and eliminating be difficulty relatively, the maintenance cost height, also high to the technical level of operators requirement, cause the hydraulic pressure movable-sieve jig to be not easy to popularize, range of application is narrow.The present mechanical type movable-sieve jig that uses, driving force is provided by mechanical component, and it is simple, reliable to have an attended operation, and cost is low, and advantage easy to maintenance receives praises from customers, but separating effect is not ideal enough.Trace it to its cause, find that existing machinery formula movable-sieve jig adopts simple toggle to drive the sieve nest motion, the characteristics of motion that this type of drive produced is undesirable, and quickreturn characteristics is not obvious, thereby causes the separating effect of lump coal good not as the fluid pressure type jigging machine.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of by regulating the arm of force angle of offset crank, reach suddenly time effect of the moving sieve of improvement and adjusting, the adjustable power reversing arrangement of the movable-sieve jig of the difficult adjusting of the anxious do that reverses of the motor-driven sieve of the existing old-fashioned mechanical type vibro-assisted jigging of solution, separating effect difference.
The technical scheme that solves the problems of the technologies described above is:
A kind of adjustable power reversing arrangement of movable-sieve jig, it is made up of power offset crank dish, moving sieve offset crank dish, axle, bolt, the power driving module of motor is connected with power offset crank dish, moving sieve offset crank dish connects moving sieve sieve nest, the big end of power offset crank dish is coaxial with the big end of moving sieve offset crank dish, and their card connects by flange.
The adjustable power reversing arrangement of above-mentioned movable-sieve jig, the big end of described moving sieve offset crank dish are symmetrical two disk structures, and gapped in the middle of two cards, the big end plate face of the shape in gap and width and power offset crank dish is complementary.
The adjustable power reversing arrangement of above-mentioned movable-sieve jig is evenly distributed a plurality of connecting bolts hole on the circumference in the center of circle with coaxial axle center on two cards of the symmetry of described moving sieve offset crank dish, and the position of the bolt hole of two cards is corresponding one by one.
The adjustable power reversing arrangement of above-mentioned movable-sieve jig is a plurality of connecting bolts of circumferential arrangement holes with coaxial axle center on the card of described power offset crank dish, and the position of bolt hole is corresponding one by one with bolt hole on the moving sieve offset crank dish card.
The utility model can be by adjusting the connecting bolt of two offset crank dish flanges, two angles between the offset crank dish are changed, adjust the desirable curve movement of sieve nest output and good urgency is returned effect with this, and can be according to ature of coal situation Field adjustment quickreturn characteristics.Advantage simple in structure, easy to operate, that the operation troubles rate is extremely low that the utility model also has is compared with the moving screen device of the hydraulic pressure of same treatment ability and also to be had tangible price advantage, is specially adapted to technologies such as jigging discharge refuse, has broad application prospects.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Be labeled as among the figure: power offset crank dish 1, moving sieve offset crank dish 2, axle 3, moving sieve sieve nest 4, bolt 5
The specific embodiment
As seen from the figure, the utility model is made up of power offset crank dish 1, moving sieve offset crank dish 2, axle 3, bolt 5.The power of motor is delivered to power offset crank dish 1 through transmission component.Power offset crank dish 1 and moving sieve offset crank dish 2 are connected by flange, after their connect together around axle 3 rotations.The moving sieve of moving sieve offset crank dish 2 connections sieve nest 4 and the moving sieve of final lifting sieve nest 4 are done reciprocal jigging motion.
Show among the figure that the big end of described moving sieve offset crank dish 2 is symmetrical two disk structures, gapped in the middle of two cards, the big end plate face of power offset crank dish 1 is clipped between two cards of moving sieve offset crank dish 2.Evenly distributed a plurality of connecting bolts hole on the circumference that on two cards of these two offset crank dishes is the center of circle with the axle center of axle 3, the position of these bolts hole is corresponding one by one, and connecting bolt 5 is fastenedly connected two offset crank dishes by these bolts hole.
Adjust the connecting bolt 5 of two offset crank dish flanges, two angles between the offset crank dish are changed, adjust the desirable curve movement of sieve nest output and good urgency is returned effect with this, and can be according to ature of coal situation Field adjustment quickreturn characteristics.
The utility model is used for mechanical movable-sieve jig, and its course of work is as follows: when movable-sieve jig was worked, moving sieve sieve nest was done upper and lower reciprocal jigging motion under the effect of adjustable power reversing arrangement.After feed coal feeds, on sieve nest, form bed.Moving sieve offset crank dish hauls from sieve nest and moves upward, and material is held up by whole layer; Sieve nest descends fast under the impetus of moving sieve offset crank dish again, and the particle of different densities is just with the sedimentation in water of different speed like this.Through moving up and down for several times repeatedly, material is realized by density stratification, and is moved forward with the sieve nest that tilts.The light material in upper strata is discharged through different outlets respectively with the lower floor spoil, reaches the purpose of discharge refuse sorting.
