Description

Belt-type powder conveyor cleaner and conveyor using the cleaner

technical field

The invention relates to the technical field of belt cleaning equipment, in particular to a cleaner for a belt-type powder conveyor and a conveyor using the cleaner.

Background technique

The material conveyed by the belt conveyor is often viscous, and part of it will stick to the working surface of the conveyor belt. It cannot be removed during unloading and enters the lower idler roller of the unloaded section. Material sticking to the idler shell will tear and roughen the surface rubber of the conveyor belt, which will accelerate the wear and damage of the conveyor belt; if the material enters the idler shell, the bearing will wear quickly. If the sticky material enters the tail redirecting roller or the vertical tensioning roller and sticks to the surface of the roller, it will cause the conveyor belt to deviate, increase the wear of the conveyor belt, and even tear the rubber layer of the roller, causing serious consequences. If the cleaning device is good, the service life of idler rollers, conveyor belts, rollers, etc. can be extended. Therefore, the cleaning ability of the cleaner is very important, and it plays a decisive role in improving the operating efficiency and reliability of the belt conveyor and reducing the failure rate and maintenance cost of the conveying equipment.

At present, most of the types of belt conveyor cleaners in China are mainly mechanical and electric according to their working principles. According to the structure, there are mainly: scraper type, rotary type, water spray type, brush type, etc. According to the materials used, there are mainly: polyester ammonia cleaner, nickel-titanium aluminum alloy, alloy rubber cleaner, etc.

Among them, the alloy rubber cleaner is widely used. It uses rubber block as the elastic body to press the cleaning block onto the surface of the conveyor belt. And on the elastic body, it affects the compression force of the elastic body, resulting in unsatisfactory cleaning effect. If the use time is a little longer, the performance of the elastomer will decrease, and phenomena such as aging, glue opening, and falling off will appear. In addition, with the wear and tear of the cleaner in use, its contact point with the conveyor will slowly move down to its limit position, and the cleaning block will be easily rolled to the other side by the conveyor, losing its cleaning ability. Will tear the tape. Moreover, due to the high frequency of replacement of the cleaner, multiple shutdowns will reduce the working efficiency of the conveyor.

Contents of the invention
