Description
Technical field
The present invention relates to a kind of conveyer, particularly a kind of long-service life high-efficiency safety-type chain band pellet type conveyer.
Background technology
In the steel industry iron-making production, pig machine equipment becomes iron block smelting the high temperature liquid iron continuous pouring that, and the iron block that falls is transported to the iron block stack-up-yard by the iron block delivery system and stores, and production and the later stage of being convenient to iron block are used.
Present iron block delivery system has that automobile directly transports, locomotive directly transports and roller moves the rotation apron conveyor.The automobile directly working process of transportation is: the iron block that falls from pig machine directly lands, and utilizes forklift to be loaded into and transports to heap iron field on the automobile.The locomotive directly working process of transportation is: the iron block that falls from pig machine falls in the locomotive, and locomotive moves to heap iron field by the traction of winch equipment, unloads by lifting magnet crane.The fall place of iron of the direct transportation request of automobile is larger; Locomotive directly transports and adopts winch to drive, and drives locomotive, is generally two trains, and every train 6-8 joint compartment needs to lay track, and also needs to arrange lifting magnet crane etc. in heap territory, iron place, and output investment ratio is larger, is difficult for adopting.
In Cast Iron Production zone hour, need to transport out the iron block of producing, then main at present what adopt is that roller moves the rotation apron conveyor.The working process that roller moves the rotation apron conveyor is: the receiving hopper that the iron block that falls from pig machine moves the rotation apron conveyor by fixedly iron block chute and roller is fallen roller and is moved on the supporting plate that rotates apron conveyor, the actuator drives drive sprocket apparatus rotates, drive sprocket drives portable chain operation, chain rotates with supporting plate, and the iron block on the supporting plate falls in the drive sprocket apparatus position.In use there is following problem in this equipment:
The constructional feature that roller moves the rotation apron conveyor is that roller is installed on the chain, and roller clip is in the centre of two carrier bars, and its space is very limited.Because roller need to snap in the driving that the drive sprocket gear teeth are realized the chain band, need to be reserved with certain space between two carrier bars, in carrying the iron block process, the little iron block that sputters is easily filled in this space, and when running to the drive sprocket position, the gear teeth also need to snap in simultaneously this space, push mutually with the little iron block of having filled in, cause carrier bar distortion, even carrier bar broken, caused the generation of conveyer accident.
Roller moves the supporting plate (connecting panel) that the rotation apron conveyor transports iron block and is slab construction, is difficult for storing little iron block and the scum of whereabouts.In carrying the iron block process, little iron block and scum easily snap between former and later two connecting panels, cause the connecting panel extrusion, and the equipment that affects normally moves, and increase the working service work capacity, and reduce the service life of equipment widely.And the supporting plate of slab construction is subjected to design space limit, and rigidity is little, and easily distortion affects the conveyer safe and reliable operation.Also have, the iron block limited amount that the slab construction supporting plate is carried, production efficiency is low.
Because roller moves the link plate structure of rotation apron conveyor and limits, driven sprocket also must adopt toothing, and after operation a period of time, chain wear easily takes off tooth after elongating, and causes conveyer to work.
In roller mobil slat conveyor production process, the portable chain band of roller mobil slat conveyor continuous movement is easily filled in little iron block or little mineral or the little lump material that sputters, push mutually with the drive sprocket gear teeth, make carrier bar distortion, sideslip or break.And the structure of roller mobil slat conveyor connecting panel also easily snaps in by little iron block or little mineral or little lump material, causes the distortion of chain band, sideslip or breaks.And the flower wheel that toothing is arranged easily makes the chain band take off tooth in using.These defectives have all affected normal operation and the use of roller mobil slat conveyor equipment.
