Description

A belt conveyor equipped with a cleaning device

technical field

The utility model relates to a belt conveyor, in particular to a belt conveyor provided with a cleaning device, which belongs to the technical field of conveying equipment.

Background technique

Belt conveyors, also known as belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, etc., for the assembly, testing, debugging, packaging and transportation of objects. The belt conveyor has strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can conveniently implement programmed control and automatic operation. When the existing belt conveyor transports materials, it is inevitable that a small amount of material will adhere to the belt and move together with the belt, especially in the belt conveyor used to transport coal, this situation is particularly obvious. During the operation of the belt conveyor used to transport coal, the coal dust generated when the coal falls from a high place through the coal drop pipe during the crushing and transfer process increases the air dust content of the air around the drop point. Large, but also in the process of operation, the return belt of the belt conveyor often occurs due to serious coal accumulation, causing the belt to deviate, causing unstable operation and precision of the belt conveyor, low conveying efficiency, and also causing wear and damage to the belt , so that the adhesive tape needs to be frequently glued or replaced, which increases the production cost.

For example, the Chinese utility model patent "New self-cleaning multifunctional two-way conveyor belt conveyor", the application number is 201120175001.1, discloses a new self-cleaning multifunctional two-way conveyor belt conveyor, the new self-cleaning multifunctional two-way conveyor belt conveyor The conveyor includes a driving device, idler rollers, belts, cleaning and drying system, a belt turning device, and a cleaning monitoring device. head and tail.
