Conveyor history and multi-faceted presentation

Conveyor history and multi-faceted presentation
   In a certain line of material handling machinery continuous transport of materials, also known as continuous gravity conveyor. Conveyor can be horizontal, inclined and vertical

conveyor can also be composed space transmission line. Transmission lines are generally fixed. Conveyor conveying capacity, long distance, also in the transportation over

Simultaneously process a number of process operations, widely used.
   Chinese ancient high drum dumper trucks and put water in the modern scraper bucket elevators and conveyors prototype. 17th century, began to apply ropeway transport bulk

materials. Mid-19th century, a variety of modern structural conveyor has emerged. In 1868, the band appeared in the UK lose

Sending machine. In 1887, in the United States appeared screw conveyor. In 1905, appeared in Switzerland steel belt conveyor. In 1906, in the United Kingdom and Germany appeared

inertia conveyor. After conveyors manufactured by mechanical, electrical, chemical and metallurgical industries impact of technological advances, constantly

Improved gradually from the workshop to complete the development of the internal transport within the enterprise to accomplish, even between enterprises between cities material

handling, mechanized and automated material handling systems become an indispensable component.
  Classification and structure of the conveyor is generally based on whether the pulling elements to be classified.
  ① conveyor having a traction member generally include traction, bearing components, drive means, tensioning means, such as redirecting means and the support member. Tractor

parts used to pass traction, can be used conveyor, drag chain or rope. Order to put the material carrying member, a hopper, bracket, or

Spreader, carrying personnel have rung. Conveyor drive unit to be power, generally consists of motor, reducer and brake (stopper) and other components. Tensioning devices

generally have two kinds of screw and a hammer, can maintain a certain tension pulling pieces and dip, in order to ensure the normal conveyor

Operation. Supporting member for supporting the tractor parts or carrying member, can be idlers, rollers, etc. A conveyor having a traction member structure is characterized by:

the material to be transported to the traction member mounted on the bearing member are joined together, or in directly mounted on the pulling element (such as belt), the

traction member around

Over the drum or sprocket connected end to end, including the transportation of materials to form branches and non-load transportation of materials unloaded branch closed loop,

continuous motion using the pulling element conveying materials. Such a wide range of conveyors, are: belt conveyors, slat conveyors, trolley conveyors

Machine, escalators, moving walkways, scraper conveyor, buried scraper conveyor, bucket conveyor, bucket elevator, overhead conveyors and overhead lifts, etc. (see figure).
  ② conveyor without pulling element different structure and composition, working member for transporting the material is not the same. Their structure is characterized by: the

use of rotational movement of the work member or reciprocating motion, or by the medium flowing in a pipe conveying the material forward. Roller conveyor

The working member of a series of rollers, the roller rotates to deliver material. Working member of the spiral screw conveyor, spiral chute rotates in order to push the

material along the trough. Vibrating conveyor working member is trough, the trough is reciprocated to convey disposed therein

Materials. Pneumatic conveying equipment, hydraulic conveying device and the container-type devices to piped gas or liquid as the medium in the pipeline transportation of

materials.
  Most uses electric drive conveyor, there is also an internal combustion engine driven, pneumatic or hydraulic driven.
  The main parameters are generally based on the requirements of material handling systems, material handling location of a variety of conditions, the production process and

material characteristics to determine the main parameters. ① Transmission capacity: conveyor transport capacity per unit time is the amount of material transported. In transport bulk materials, transportation of materials per hour mass or volume calculations; during transportation into items, the number of pieces

per hour transport calculations. ② Conveyor speed: increase transmission speed can increase transmission capacity. In order to make conveyor belt retractor

Cited pieces and feed length is large, the conveying speed increasing day by day. But high-speed operation of the belt should pay attention to vibration, noise, and start

braking and other issues. For chains as traction element conveyor, conveyor speed should not be too large to prevent increased dynamic loads. Work simultaneously

Arts operated conveyors, conveyor speed production process requirements should be determined. ③ component size: scantling including conveyor belt width, belt width, hopper

volume, pipe diameter and vessel size. These have a direct impact scantlings conveyor conveying capacity. ④ lose

Delivery length and angle: transfer line length and inclination conveyor directly affect the size of the total resistance and the power required.
  Development trend towards the development of the conveyor are: ① continue to large-scale development. Large transmission capacity, including large-scale, large single length

and large transmission angle and other aspects. Hydraulic conveyor length reached 440 km or more. Belt conveyor length of nearly 15 km single,

And has appeared composed by a number of Taiwan Contact B two places "belt conveyor path." Many countries are exploring long-distance, large-capacity transport of materials

better continuous conveyor structure. ② to expand the use of the conveyor. Developments in high temperature, low temperature, corrosive, radioactive

Sex, flammable substances in the work environment, as well as capable of delivering fiery, explosive, Pellet, sticky material conveyor. ③ the conveyor structure to meet the

automated material handling system to control stand-alone asked for. As used in automated sorting post office parcel trolley conveyor

Sorting machine should be able to meet the requirements of such action. ④ reduce energy consumption in order to save energy, the field of conveyor technology has become an

important aspect of research. Has one ton material handling energy consumed by one kilometer conveyor selection as one important indicator. ⑤ reduce all kinds of conveyors

Generated during operation of dust, noise and emissions.
