Scraper conveyor is also called slipper; electric slipper; chain conveyor. It is a conveyor that uses a scraper chain to pull and transport bulk material in the tank. Scraper conveyor coal mines, chemical mines, metal mines and power plants and other important means of transport for transport of materials. It consists of a central trough, chain, scraper and traction system. Among them, the central trough is the main part of the scraper conveyor. The steel central trough has a history of nearly one hundred years. In the long-term use process, it has the following disadvantages: 1 heavy, installation and handling time and labor; 2 central trough is generally Made of 6-15mm steel plate, it is easy to deform when subjected to large impact, and it is difficult to repair; 3 poor corrosion resistance; 4 poor wear resistance; 5 material and central groove have large friction coefficient, and the scraper conveyor has high power Partially consumed by the friction between the material and the central trough, resulting in excessive energy consumption and increased investment.
Scraper conveyor operating procedures:
1. Dress neatly and hold a valid certificate.
2. Conscientiously implement the safety regulations of the coal preparation plant, familiarize yourself with the process flow of the post and the upper and lower ranks, and the sequence of starting and stopping of the equipment, and clarify the centralized control signals.
3. Before starting the car, you must carefully check whether the mechanical equipment and the screws of each part are normal.
4. During the inspection process, personnel should stand in a safe position, and it is forbidden to penetrate all parts of the body into the scraper and the box.
5. During operation, carefully check the operation of the chain plate, the tightness of the chain, and whether the chain and the head wheel are meshed properly.
6. The first round of sundries or the goods in the box must be cleaned up.
7. If it is found that the chain is broken or the goods are pressed, stop immediately. When handling, the personnel stand on both sides of the machine body. It is strictly forbidden to handle the fault during operation.
