A conveyor is a material handling machine that continuously transports materials on a certain line, also known as a continuous conveyor. The conveyor can be transported horizontally, obliquely and vertically, or it can form a space conveyor line, which is generally fixed. The conveyor has a large conveying capacity and a long transportation distance, and can also complete several process operations simultaneously in the conveying process, so the application is very extensive.
Guangzhou Hansen automated conveyor belt equipment - conveyor belt introduction
In the 17th century, the United States began to use aerial ropeways to transport bulk materials; in the mid-19th century, various modern conveyor belt conveyors appeared one after another.
In 1868, belt conveyors appeared in the United Kingdom; in 1887, screw conveyors appeared in the United States; in 1905, steel belt conveyors appeared in Switzerland; in 1906, inertial conveyors appeared in the United Kingdom and Germany. Since then, the conveyor belt conveyor has been affected by technological advances in machinery manufacturing, electrical machinery, chemical industry and metallurgical industry, and has been continuously improved. It has gradually evolved from the completion of the interior of the workshop to the completion of material handling within the enterprise, between enterprises and even between cities. An integral part of the mechanization and automation of material handling systems.
Conveyor belts are generally classified by the presence or absence of a tractor.
A conveyor belt having a traction member generally includes a traction member, a carrier member, a driving device, a tensioning device, a redirecting device, a support member, and the like. The traction member is used for transmitting the traction force, and the conveyor belt, the traction chain or the steel wire rope can be used; the bearing member is used for receiving the material, and the hopper, the bracket or the spreader; the driving device powers the conveyor, generally by the electric motor, the speed reducer and Brake (stopper) and other components; the tensioning device generally has two types of screw type and heavy hammer type, which can maintain the tension and sag of the traction piece to ensure the normal operation of the conveyor belt; the support member is used to support the traction member or load For the components, rollers, rollers, and the like can be used.
The structural feature of the conveyor belt device with the traction member is that the conveyed material is installed in the bearing member coupled with the traction member, or directly on the traction member (such as the conveyor belt), and the traction member bypasses each roller or the sprocket Connected to form a closed loop comprising a loaded branch carrying material and a unloaded branch that does not carry material, the material being conveyed by continuous motion of the traction member.
There are many types of conveyor belts, such as belt conveyors, slab conveyors, trolley conveyors, escalators, moving walkways, scraper conveyors, buried scraper conveyors, bucket conveyors, bucket elevators. , hanging conveyors and aerial ropeways.
The conveyor belt equipment without the traction members has a different structural composition, and the working members for conveying the materials are also different. Their structural features are: the use of the rotary motion or reciprocating motion of the working member, or the use of the flow of the medium in the pipeline to transport the material forward. For example, the working member of the roller conveyor is a series of rollers, and the roller rotates to convey the material; the working member of the screw conveyor is a spiral, and the spiral rotates in the trough to push the material along the trough; the work of the vibrating conveyor The member is a trough, and the trough reciprocates to transport the material placed therein.
Future conveyor belt equipment will develop towards large-scale development, expanding the scope of use, automatic material sorting, reducing energy consumption, and reducing pollution.
Large-scale includes several aspects such as large conveying capacity, large single machine length and large conveying inclination. The length of the hydraulic conveying device has reached 440 km. The length of the belt conveyor has been nearly 15 kilometers, and there have been a number of "belt conveyors" that link the two sides. Many countries are exploring a more complete conveyor structure for long-distance, large-volume continuous conveying of materials.
Expanding the scope of use of conveyors refers to the development of conveyor belts that can work in environments with corrosive, radioactive, and flammable substances under high temperature and low temperature conditions, as well as conveyor belts that can transport hot, explosive, agglomerated, and viscous materials. .
