Description

Plate link chain bucket conveyer

The utility model relates to the solid material load transfer device.

In the industries such as metallurgy, chemical industry, building materials, the load transfer device of being made up of hard ware is all adopted in high temperature, the heavy conveying of decreasing piece granular solids material, as bucket elevator, skirt-type conveyer etc.The characteristics of these equipment are that structure is complicated, from great, and the cost height, service conditions is abominable, is the important operation of continuity production technology.Because structure is outmoded, there are many problem demanding prompt solutions aborning in these equipment: in the chain bucket systematic part life-span short (1～1.5 year), maintenance is frequent, and the labor intensive financial resources are many, and production threatens bigger to continuity; It is serious that equipment leaks material, pollutes surrounding environment, and it is big that the workman clears up the labour power of Lou expecting, even can cause equipment breakdown; In addition, be difficult to keep normal quality of fit, noise and vibration aggravation have more quickened the damage of equipment; Also have, high position in storehouse and remote conveying task unit can not be finished, and can only the multimachine relay carry, and it is big to form investment, the situation of difficult management.

The purpose of this utility model provides a kind of plate chain bucket carrier of new structure, can eliminate the defective of original bucket elevator and skirt-type conveyer, equipment performance is greatly improved, the chain bucket systematic part life-span can reach more than 5 years, but abatement apparatus leaks material, can keep normal quality of fit for a long time, abate the noise and vibrate, make equipment steady, safety, failure-free operation; Can significantly reduce power consumption; Unit can be finished high position in storehouse and remote conveying task, and new construction is applicable to level, angle and vertical angle conveying arbitrarily.

Plate chain bucket carrier of the present utility model is by motor, reductor, drive sprocket, constituted by movable sprocket, conduction chain, hopper and frame, when motor drags drive sprocket when rotating through reductor, to drive the chain bucket system that forms by conduction chain and hopper along moving on the track of frame, with the purpose of realization convey materials.The on line of drive sprocket and passive centre of sprocket and the angle β between the horizon are called the equipment stagger angle.Major technique characteristics of the present utility model are that the hopper otic placode is arranged at the two sides of hopper respectively and near the chain line of centers, is equipped with 2 studs on otic placode, to gain in strength.Below the chain line of centers, be provided with the hopper of trapezoidal cross-section, front strickle and back angle α=360 between the strickle °/Z ± 5 °, wherein Z be main, by the number of teeth of movable sprocket.For anti-leak-stopping material, can be provided with skirtboard on the two end side panels top of hopper, the skirtboard of adjacent skips both sides overlaps mutually, and is provided with striker plate at the front end of front strickle.For the hopper of equipment stagger angle β≤35 °, both sides are straight skirtboard, and its striker plate is parallel and downward with the back strickle.For the hopper of equipment stagger angle β＞35 °, both sides are trapezoidal skirtboard, and its striker plate becomes 10 °～15 ° angles with front strickle.The roller of conduction chain can separate and be arranged at the chain link position intermediate with bearing pin, sleeve pipe, roller does not participate in the transmission engagement of sprocket wheel and chain.Can be provided with antifriction-bearing box in the roller, the antifriction-bearing box endoporus is contained on the hollow shaft sleeve, and nationality makes the bolt that tightly passes inner plate hole and hollow shaft sleeve endoporus the two ends of hollow shaft sleeve compress mutually and can not relatively rotate with the inner plate side, and the roller both sides are provided with labyrinth packing.The tooth of sprocket wheel is preferably made to insert by the high strength anti alloy steel and is assemblied on the wheel hub, has not only reduced cost but also easy access.

The utility model can bring tangible economy and society benefit than original load transfer device: because the improvement of structure and stressing conditions makes the chain bucket systematic part life-span of carrying material improve 2～4 times than original, save a large amount of financial resources and manpower; Because equipment can long-term safety, the failure-free operation, has prolonged the period of inspection and repair, guaranteed balanced and stable production will bring huge process efficiency; The equipment of having eliminated leaks material, will improve environmental sanitation, and eliminates the heavy cleaning work of workman, also helps equipment safety operation; Because part life is long, can keep normal quality of fit for a long time, has eliminated noise and vibration, the high position in storehouse that unit can be finished more than hundred meters is carried with remote, has avoided the multimachine relay to carry, and invests convenient management thereby save; Roller has reduced resistance of motion after using antifriction-bearing box instead by plain bearing significantly, and actual measurement shows can reduce power consumption 30～35%(under identical traffic capacity); Because the increase of hopper bearing material section is for the wide traffic capacity that increases of identical bucket.For certain traffic capacity, can reduce the wide and specification of equipment of bucket, thereby reduce weight of equipment and investment; Structure of the present utility model both can be used for horizontal feed, also can be used for the inclination transportation of any apparatus stagger angle, until vertical transport; Not only can be used for the design of new installation, also can be used for the technological change of the fixed old factory of equipment disposition.Do local the transformation in conjunction with maintenance with less fund, can obtain brand new equipment performance and considerable benefit.
