The previous article has mentioned the types of conveyor belt cleaners, because there are many, and it is impossible to use all of them on the conveyor, so this article only analyzes the common cleaners with a wide range of applications.
1. Alloy rubber cleaner
The alloy rubber cleaner is an ideal cleaner used in the conveyor industry since the 1980s. It is installed at the head drum. It mainly relies on the elasticity of the rubber bar, and the scraper material is changed from rubber to hard alloy. , close to the surface of the conveyor belt after the material and the conveyor belt are separated. Clean the material stuck on the conveyor belt.
The alloy rubber cleaner is mainly composed of a plurality of alloy scrapers, scraper frames, rubber elastic bodies, beams, adjustable fixing frames, etc., and its structure is simple and compact. The working pressure should be moderate, and at the same time, the line contact between the cleaning plate and the driving drum should be uniform, so as to achieve the best cleaning effect. The material cleaned by the alloy rubber cleaner will directly fall into the head cone of the continuous conveyor, and be conveyed together with other materials. There is no problem of material accumulation and material spilling on the return belt. To achieve a better cleaning effect, the more mature experience is to increase the number of cleaners at the head drum and use them together. Such as alloy rubber cleaner P, H type and use. Add a cemented carbide scraper cleaner; when the return conveyor belt enters the lower idler, the lower idler adopts a comb-shaped idler or a spiral idler or a V-shaped comb idler, which can achieve a better cleaning effect.
2. PUR polyurethane belt cleaner
The PUR polyurethane belt cleaner is installed at the drive roller of the belt conveyor. Its scraper is made of polyurethane composite material and is integrally formed with a mold. The scraper has a flat surface, good straightness, low friction, high wear resistance and high strength. , It has a fairly stable scraping effect, which can effectively remove the fine particles and wet sticky materials on the residual belt.
Its characteristics are: excellent scraping effect, no risk of scraper jumping; scraper and fixed seat are combined in the form of a dovetail groove, and there is a top tightening device to eliminate clearance; three-layer scraper set, with detachable fixed seat, can It is very easy to install or maintain by pulling and replacing on the side of the hopper; the replacement of the knife seat is simple and fast, and the contact pressure is pushed and stabilized by the side of the hopper, and can be fine-tuned if necessary; long service life: low and stable scraper and belt The contact pressure can not only maintain the excellent scraping effect, but also effectively improve the service life. Generally, it can be used for 1 to 3 years without damaging the belt. The use of high-molecular polyurethane, coupled with better comprehensive mechanical properties, prolongs the service life of the product.
3. Tungsten Carbide Scraper Cleaner
The alloy cleaner mainly cleans small particles of machine media, which can effectively ensure the cleanliness of the conveyor belt. Its novel structure, unique buffer compensation device, good anti-shock vibration performance of conveyor belt, the cleaning effect is good, and it is not easy to damage the conveyor belt. It also comes with a high-performance standard component system, including system support tubes, support tube extensions and elastic buffers, from specially crafted high-quality carbide scrapers for extra long service life. The patented design of the adjusting mechanism is convenient for the adjustment of the contact pressure between the scraper and the conveyor belt, and after the scraper is worn, the metal scrapers on both sides are adjusted to form a circular arc outward, which can effectively prevent the edge of the scraper from damaging the belt surface. Guard plate, which can well prevent material accumulation and scaling.
Its characteristics are: excellent cleaning effect, optional conversion mechanical parts to be assembled outside the conveyor belt frame, suitable for the installation and adjustment of the two-way running conveyor belt, easy maintenance, small maintenance workload, and the humidity of transported materials is 5% The above will also be cleaned up.
4. Empty segment cleaner
In the process of conveying the material on the conveyor belt, it is inevitable that the material will be withdrawn due to the deviation of the conveyor belt, so that the material will fall on the return section of the conveyor belt, be brought to the tail of the machine, and be drawn into the tail redirecting roller, sticking to the conveyor belt. It is connected to the surface of the roller, which causes uneven tension of the conveyor belt and damages the conveyor belt. Therefore, an empty section cleaner must be installed at the tail of the continuous conveyor, and the return conveyor belt is adjacent to the tail turning roller. The empty section cleaner can use rubber plate or wear-resistant lining plate as the cleaning plate, which can be made into "herringbone" shape and "/" shape. After adjusting the contact between the cleaning plate and the non-bearing surface of the conveyor belt, place the two ends Fixed on the rack of the equipment. In order to compensate for the wear of the cleaning plate, springs are often used to automatically adjust the contact between the cleaning plate and the conveyor belt to ensure the quality of cleaning.
The Tungsten Carbide Secondary Conveyor Belt Scraper Cleaner that we produced has high corrosion resistance, high wear resistance and a longer service life.
