First, accurate installation and maintenance to ensure that the specifications of the scraper chain are the same, the rolling position is flexible. To ensure the straightness of the inner wall of the casing, it is not allowed to have the upper and lower misalignment of the interface flange and the guide rail, and the connection should be smooth and without steps. In addition, the interface flange should be straight and the verticality of the interface should not exceed 1mm to ensure that the scraper chain does not cause scratches during operation, which is conducive to normal operation and reduce wear and power consumption.

Second, adjust the appropriate gap between the scraper and the bottom plate of the machine. This is an important issue, which affects the service life and delivery efficiency of the equipment. Obviously, the gap is too small, and the clinker is easily caught between the scraper and the machine slot, causing damage to the scraper or the bottom of the machine slot, and even a chain break accident occurs in severe cases. If the gap is too large, the conveying efficiency is lowered. The size of the gap depends on the particle size of the clinker and is generally determined by the following formula: A>D/2+5 where A represents the gap between the squeegee and the bottom plate (mm); D represents the maximum particle size (mm) of the clinker. The clinker calcined by the rotary kiln is cooled by a grate cooler. The maximum particle size of the hammer crusher after crushing is about 25 mm, and the gap between the control scraper and the bottom trough plate is above 17.5 mm, which can reduce the bottom trough plate and the scraper. Wear and extend its service life.

3. Accurate, fair and timely maintenance and inspection. Strengthen the inspection and check whether the scraper chain is deformed or broken. The pin on the pin should be repaired or replaced in time. When the scraper chain is loose, it should be adjusted in time, so that the scraper chain often works under the proper tension condition, find the problem, deal with it in time, and prevent it from happening.

4. Fair design and good manufacturing quality The scraper is a load-bearing member made of 16Mn steel and welded directly perpendicular to the chain. The scraper chain is a traction member, which is designed as a double-plate chain. It is stamped and formed by two steel plates and welded into a chain rod, which is then connected by a pin. Evergreen is characterized by its reliability, simplicity of manufacture and low price. In the working process, the scraper chain has to overcome a large frictional resistance and bears a large dynamic load and static load. Therefore, the scraper chain is heat-treated after manufacturing and welding, so that it has high strength, toughness and resistance. Grinding.
