The material conveyed by the belt conveyor is often sticky, such as coal dust, mud, powdery materials. After the material is unloaded at the head position of the drum, there will still be material stuck on the working surface of the conveyor belt (belt) during the return journey, which cannot be completely removed. At this time, the adhered material will enter the empty section of the conveyor belt. On the idler, the rollers are soiled, and the attachments can also be adhered to the rollers, so the use of a cleaner on the head of the conveyor belt prevents the belt from being thrown along the way during the return journey. In addition, during the operation of the conveyor belt, the material of the load-bearing section will also fall on the non-working surface. As the conveyor belt runs forward, the uncleaned material will not only get stuck between the drum and the conveyor belt, or even the drive roller. There will be adhesion, damage to the drum surface and the conveyor belt, so that the conveyor belt is deflected or damaged. Therefore, it is better to assemble the empty section cleaner at the tail of the drum to make the conveyor belt achieve better cleaning effect. The operation of the cleaner is normal and the effect is good, and the service life of the belt conveyor and the conveying equipment of the belt conveyor can be prolonged. In addition, since the conveyor belt is generally long, the dust is scattered or bonded, which will also affect the environment. Proper use can also reduce environmental pollution.

Choosing the right cleaner?

       Conveyor belt cleaners come in a variety of styles, so be sure to choose a cleaner that is suitable for the material properties. At the same time, after the cleaner is installed, it is necessary to make timely adjustments to adapt to the performance of the material.

        Before a coal mine, an alloy rubber cleaner was used to clean the working surface of the conveyor belt. The cutter body was pressed for 200m, and there was no connection between the two. When the cleaner was installed, the cutter head was difficult to be close to the conveyor belt surface, and the cutter head suspension was easy to be Bounce, the effect is not good.
        When the material to be conveyed contains a block (such as agglomerate of mature gypsum) or has large particles (such as broken or damaged mesh, large particles can pass), the suspension will be opened, and the suspension has poor elastic compensation and cannot be restored. If the upper cutter head is not in contact with the conveyor belt, the material adhering to the conveyor belt will not be removed through the gap. Especially when the materials conveyed, such as clinker, moisture-bearing coal, etc., have a large static accumulation angle and a large viscosity, where the dropped material will accumulate to a certain height, and the working surface of the return conveyor belt will be renewed. Stick to the material, some will be brought to or out of the rack outside the funnel, manual cleaning is difficult. If the suspension is changed to a whole steel plate, but it still cannot change the deformation of the tool holder, it will not rebound, and the cutter head cannot contact the conveyor belt, which may cause the working surface to be cleaned. In addition, the maintenance of the alloy cleaner is troublesome. It is necessary to regularly check whether the contact and the force of the cleaning plate meet the requirements, and the adhered material must be cleaned in time, otherwise the blade frame will be deformed and the elastomer will be affected. The vibration absorption effect.
        Changyi Company recommended Changyi H-type head-mounted polyurethane cleaner. The material of the cutter head has uniform polymerization degree and hardness of 80-90 degrees in Shore. The special additive is added to the cutter head during the synthesis process to increase the degree of molecular polymerization. In addition, there is a special lubricant in the additive, which ensures a good melting effect on the contact surface of the cleaner and the belt, and effectively protects the belt. At the same time, its material has better wear-resisting effect than other domestic counterparts.

II.

       Improper installation of the cleaner can also cause problems. A cement factory in Huizhou, Guangdong Province has been using Changyitou Road Polyurethane Cleaner. In October 2018, customers reported that one of the conveyor belts was running for less than 2 months, but the polyurethane polymer head equipped with it was worn 1/3. The same model and cutter head are used normally on other conveyor belts. Changyi engineers visited the scene to find out the cause and analysis. Finally, the frame of the cleaner was locked too tightly, and the spring was adjusted too much. When the cleaner was running, the cutter head was dragged backward in the running direction. In the remote, its installation angle is too large, which will cause the friction between the cutter head and the conveyor belt to be large, and the cutter head wears fast. In this case, it is only necessary to adjust the nut or bolt to make the cutter head properly tighten the conveyor belt.

       In summary, although the cleaner is only a small part on the belt conveyor, as a production and sales manufacturer, when recommending the customer to choose the cleaner, the customer must choose the appropriate cleaner according to the material characteristics and the use environment. It is not only for the purpose of selling and making money; as a manufacturer, it is also necessary to remind the customer that after the installation of the cleaner, it is necessary to check whether the cutter heads are in a straight line, and whether the pressing force of the conveyor belt is in an appropriate range, whether the installation is correct? In addition, customers should be reminded to pay special attention to the quality of the vulcanized joint. If there is a bubble in the vulcanization position, after running for a period of time, the vulcanized knot will stratify and squash, and the joint needs to be re-vulcanized. Otherwise, the cleaner may scrape the conveyor belt, which is serious. If the alloy cleaner head also tears the conveyor belt. Therefore, when running at full load, it is also necessary to patrol the conveyor belt for the position of the vulcanized joint.
