Abstract
A mechanical movable-sieve jig movable-sieve device belongs to the solid separating equipment technology field, which is used to solve problems of unclearness of quick-return characteristic of a mechanical movable-sieve jig and lack of effects of lump coal sorting. The movable-sieve device comprises a power mechanism and a sieve body, both of which are motion-transmitting connected. The power mechanism comprises a motor, a belt transmission assembly, a chief shaft, a cam assembly and a retraction spring after improvement, wherein the cam assembly comprises a cam and a roller follower. The motor is drivingly connected with the chief shaft through the transmission assembly, the cam is fixedly arranged on the chief shaft, the roller follower is situated upon the sieve body, the cam contacts and presses the roller follower, and the retraction spring is connected with the sieve body and the stand frame. The power mechanism of the utility model has a clear quick-return characteristic under the joint effect of the lifting of the cam and the quick-return of the retraction spring, produces an ideal moving curve, realizes effective stratification of the material layer under the basis of guaranteeing the thickness of the bed used in a movable-sieve jig and has a good sorting effect. The utility model also has the advantages of simple conformation, convenient operation, and extreme low error rate or the like.
Description
Technical field
The utility model relates to a kind of wash coaling equipment, is a kind of moving screen device of mechanical type movable-sieve jig specifically, belongs to the solid separation equipment technical field.
Background technology
Movable-sieve jig is that a kind of external force driving sieve nest that utilizes moves up and down in aqueous medium, causes material periodically loose, realizes the screening installation by density stratification, is widely used in the sorting of coal washery to raw coal.The core component of movable-sieve jig is screen device, and moving screen device comprises actuating unit and sieve nest, and wherein actuating unit rises the cycle movement that plunges for sieve nest is slow driving force is provided.Actuating unit has fluid pressure type and mechanical type, the actuating unit of hydraulic pressure movable-sieve jig is operated 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, actuating unit adopts 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, the actuating unit of finding existing machinery formula movable-sieve jig adopts 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
The utility model is used to overcome the defective of prior art and provides a kind of is that actuating unit, quickreturn characteristics are obvious, the moving screen device that is used for movable-sieve jig of good separation effect with the cam extension spring.
The alleged problem of the utility model is solved by following technical scheme:
A kind of moving screen device that is used for mechanical movable-sieve jig, constitute by actuating unit and sieve nest, both move to transmit and connect, its special feature is: described actuating unit comprises motor 6, band transmission component 4, main shaft 3, cam pack and return spring 8, wherein cam pack is made up of cam 2 and roller driven member 7, described motor is connected with spindle drive through the band transmission component, cam is installed on the main shaft, the roller driven member is positioned at sieve nest 5 tops, cam presses the roller driven member, and described return spring connects sieve nest 5 and frame 9.
The above-mentioned moving screen device that is used for mechanical movable-sieve jig is set up eccentrically mounted weight piece 1, and the eccentric direction of eccentrically mounted weight piece is opposite with the eccentric direction of cam to be provided with.
The above-mentioned moving screen device that is used for mechanical movable-sieve jig, described cam are positioned at the main shaft middle part, and described eccentrically mounted weight piece is two, and they lay respectively at the main shaft two ends.
The utility model improves the not good enough problem of lump coal discharge refuse effect at the moving screen device of existing machinery formula movable-sieve jig, adopted the actuating unit of cam extension spring for moving screen device, it is as follows to improve the back main feature: 1. the actuating unit of described device is under cam lift and the anxious acting in conjunction of returning of extension spring, quickreturn characteristics is obvious, the curve movement ideal that produces, can realize the effectively layering of bed of material ground on the basis that guarantees thickness of bed layer, performance indications are near fluid pressure type movable-sieve jig level; 2. be provided with the eccentrically mounted weight wheel in the actuating unit, power is carried out certain compensation, make transmission more steady effectively, also can reduce power consumption; 3. simple in structure, easy to operate, the operation troubles rate is extremely low, compares with the moving screen device of the hydraulic pressure of same treatment ability to have tangible price advantage.Based on above-mentioned advantage, the utility model be specially adapted to heavily be situated between discharge refuse and bradford breaker, artificial dirt extraction etc. have broad application prospects.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Number in the figure is expressed as follows: 1. eccentrically mounted weight piece; 2. cam; 3. main shaft; 4. band transmission component; 5. sieve nest; 6. motor; 7. roller driven member; 8. return spring; 9. frame.
The specific embodiment
Referring to Fig. 1, the utility model is made of actuating unit and sieve nest 5, and actuating unit is a mechanical device.Described actuating unit adopts the cam extension spring to drive the sieve nest motion, under the acting in conjunction of cam lift and return spring, and the desirable and good quickreturn characteristics of exportable desirable curve movement.As seen from the figure, actuating unit comprises motor 6, band transmission component 4, main shaft 3, cam pack and return spring 8, cam pack is made up of cam 2 and roller driven member 7, the power of motor is delivered to and main shaft 3 through the band transmission component, cam is installed on the main shaft, the roller driven member is positioned at sieve nest 5 tops, and cam presses the roller driven member, and return spring connects sieve nest 5 and frame 9.Actuating unit also is provided with eccentrically mounted weight piece 1, and the eccentric direction of eccentrically mounted weight piece is opposite with the eccentric direction of cam to be provided with, and the eccentrically mounted weight piece is two, and they lay respectively at the main shaft two ends.This setting can be carried out certain compensation to power, makes transmission more steady effectively, also can reduce power consumption.
It is as follows that the utility model is used on the mechanical movable-sieve jig its course of work: transfer when eliminating machine work at moving sieve, sieve nest swings up and down under the actuating unit effect.After feed coal feeds, on sieve nest, form bed.Sieve nest moves upward during the cam rise, and material is held up by whole layer; During the cam backhaul under the return spring effect sieve nest descend fast, the particle of different densities is with the sedimentation in water of different speed.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.
