外文资料Bucket elevatorBucket type lifting machine is a fixed device of mechanical conveying equipment, mainly used in powdery, granular and small block materials for vertical lifting, can be widely used in various size of feed mill, flour mill, rice mill, refineries, starch factory and grain depot, port and dock bulk material.Bucket elevator for vertical lifting through the crusher limestone, coal, gypsum, clinker, dry clay block granular material as well as raw material, cement, coal and other powder materials. According to the different speed of hopper, the bucket elevator can be divided into three types: centrifugal discharge, gravity discharge and mixed type discharge. Centrifugal type unloading material bucket speed faster, for conveying powdery, granular and small shape grinding material cut small; gravity discharge material slow speed of the bucket for bulk transport, the proportion of larger, grinding Zhuo materials, such as limestone, clinker, etc. The traction component of the bucket elevator has several kinds of chain, plate chain and adhesive tape. Ring chain structure and manufacture of relatively simple, is also very strong connection with the hopper, conveyor mill Zhuo of material, wear a small chain, but the larger self. Chain plate structure of a solid, lighter weight, applicable to a large quantity of hoist lifting, but articulated joint is easy to wear out, the tape has the advantages of simple structure, but not suitable conveyor mill cut large materials, the ordinary belt material temperature does not exceed 60 DEG C, steel cord belt clip allows the temperature of the material up to 80 DEG C, heat-resistant tape allows material temperature of 120 DEG C, ring chain, plate chain conveying material temperature of up to 250 DEG.Scope of applicationThis series bucket elevator is suitable for conveying powdery, granular and small shape of grinding Zhuo and grinding Zhuo small materials, such as coal, cement, stone, sand, clay, iron ore and other, because the elevator traction mechanism is a circular chain, thus allowing transport of high temperature materials (material temperature of not more than 250 DEG C). General conveying height up to 40 meters.functionThe lifting equipment with large conveying capacity, high lifting height, stable and reliable operation, long life advantages, its main properties and parameters with the vertical bucket type lifting machine (jb3926-85) (the standard equivalent with reference to the international standards and foreign advanced standards), ring chain traction with the mining high strength ring chain MT36-80, the lifting machine is suitable for conveying powder, thus allowing higher temperature of the material conveying.characteristicDriving powerDrive power is small, the inflow type feeding, induction type unloading material, large capacity hopper intensive layout. The material lifting almost no feed back and dig material phenomenon and is therefore invalid less power.Lifting rangeLifting range, this type of hoist the kinds of materials, performance requirements, not only can improve the general powdery, granular materials and improve grinding Zhuo of larger material. Good sealing performance and environmental pollution.Operation abilityGood operating reliability, advanced design principles and processing methods to ensure the reliability of the whole operation, no failure time more than 20 thousand hours. The lifting height is high, and the lifting machine runs stably, so the height of the lifting height can be achieved.service lifeThe use of long life, enhance the feeding machine to take into the type, without the need to use a bucket material, material rarely occur extrusion and collision phenomenon. This machine in the design to ensure the materials in the feeding and unloading is less scattered, reduces the mechanical wear.working principleHopper to material from below the storage scooping up, along the conveyor belt or chain ascension to the top, bypassing the top wheel turned downward, bucket hoist material poured into the receiving groove. Belt conveyor belt conveyor belt generally used rubber belt, installed in the bottom or above the driving drum and the upper and lower on the roller. Chain drive bucket elevator is generally equipped with two parallel transmission chain, on or below a pair of transmission chain wheel, or above is a pair of wheel. Bucket elevator is generally equipped with a chassis, in order to prevent the dust in the bucket elevator.structureAirplane partsThe upper casing, shaft parts, reducer, coupling and motor assembled together.Middle casingAccording to the height of lifting, configured with different number of middle casing combined is able to meet the needs of.Lower partBy the bottom casing, driven shaft parts and tensioning device to form a whole. The side door of the cabinet can be opened, and the inner side of the casing can be checked for cleaning.Chain and hopper
