[ Flat belt conveyor manufacturers] PUR polyurethane belt cleaner usage
The PUR polyurethane belt cleaner is installed at the driving roller of the belt conveyor. Its scraper is made of polyurethane composite material, which is integrally processed and formed with a mold. The scraper surface is flat and straight, with low friction, high wear resistance, and high strength. It has a very stable scraping effect, which can effectively remove the fine particles and wet sticky materials on the remaining belt. The pre-pressure regulator ensures the stable contact pressure between the scraper and the belt.
The scraper can generally be used for 1 to 3 years without hurting the belt. The use of high-molecular-weight polyurethane, combined with better comprehensive mechanical properties, extends the product's service life. The design has a compact structure, reasonable preparation, and the product is light, beautiful, and easy to operate. Spare parts are interchangeable and adjustable, making installation, commissioning, replacement and maintenance easier.
2) Carbide scraper cleaner
The alloy cleaner mainly cleans small particles and their media. The humidity of the conveyed materials can be cleaned when the humidity is above 5%. Carbide scraper cleaner is installed on the head of the belt conveyor. The scraper material is made of hard alloy. There are two types of single sheet and double sheet. The weight of the scraper on the conveyor belt can be changed by adjusting the weight to achieve a complete The effect of cleaning materials.
It has a novel structure, a unique buffer compensation device, good resistance to shock and vibration of the conveyor belt, good cleaning effect, and is not easy to damage the conveyor belt. It is also equipped with a high-functional standard component system, including a system support tube, a support tube extension, and an elastic buffer device. The adjustment mechanism facilitates the adjustment of the contact pressure between the scraper and the conveyor belt, and adjusts the direction of the metal scrapers on both sides after the scraper wears. The outer shape is a downward arc, which effectively prevents the edge of the scraper from damaging the smooth PE blade guard of the belt surface, which can prevent material accumulation and scaling.
3) Empty section cleaner
The empty section cleaner uses a rubber plate or a wear-resistant liner as the cleaning plate, which can be made into a "herringbone" shape or a "/" shape, and is installed on the return branch of the conveyor belt, on the upper side of the conveyor belt, near the tail roller or vertically pulled The tightening device is turned towards the drum. In order to compensate for the wear of the cleaning plate, a spring is often used to automatically adjust the contact between the cleaning plate and the conveyor belt to ensure the cleaning quality.
4) Rotary roller brush cleaner
Rotary roller brush cleaner is a new product, which has only been put into use in China in recent years. It can effectively clean the surface of the roller and the bottom of the conveyor belt. The cylindrical nylon brush is driven by the motor, and the tip of the brush slightly contacts the belt surface. The rotation direction of the nylon brush is opposite to the running direction of the return conveyor belt, so that the particulate material stuck on the surface of the belt is brushed to achieve the purpose of thorough cleaning. It has been widely used in coal conveyor belts in power plants, chemical industry, sugar manufacturing, pharmaceuticals, ports and terminals.
The rotary roller brush cleaner is composed of a motor, a reducer, a cleaning roller, a coupling, a bearing seat, and an adjustment frame. Its performance characteristics are as follows: ① Integrated design, easy installation and adjustment, and strong applicability. ②During the cleaning process, the deviation of the tape will not be caused. ③ Safe and reliable, long service life and low maintenance cost. ④ When the cleaner is in operation, the cleaning points are in continuous contact, and the cleaning is powerful and the cleaning effect is good. ⑤ Nylon brush is processed by special process, without sticking or scaling. ⑥ No wear on the tape, prolong the service life of the tape.
5) Alloy rubber cleaner
The alloy rubber cleaner is installed at the head roller. It mainly uses the elasticity of the rubber rod. At the same time, the scraper material is changed from rubber to hard alloy. After the material and the conveyor belt are separated, they are close to the surface of the conveyor belt. materials.
The gold rubber cleaner is mainly composed of multiple alloy scrapers, scraper frames, rubber elastic bodies, beams, adjustable fixing frames, etc., and its structure is simple and compact. The fixing frame can be adjusted to adjust the distance between the scraper and the driving roller. And then turn the beam shaft to lock the bolt after the contact pressure between the scraper and the driving roller reaches 100 ~ 150N.
The material cleaned by the alloy rubber cleaner will directly fall into the head cone of the continuous conveyor, and be transported together with other materials, there is no problem of accumulation of materials and material spilling on the return belt.
To achieve better cleaning results, the more mature experience is to increase the number of cleaners at the head drum and use them in combination. Such as alloy rubber cleaner P, H type combined use. Add a hard alloy scraper cleaner; when the return conveyor enters the lower idler, the lower idler uses a comb idler or a spiral idler or a V-shaped idler, which can achieve better cleaning results.
