1. Introduction Carbon separation screen, as an indispensable equipment in the industrial field, especially in the coal processing process, its performance directly affects the efficiency and quality of coal separation. In order to ensure that the carbon screen can run stably for a long time, improve its service life and reduce the failure rate, it is particularly critical to carry out regular maintenance and maintenance. In this paper, the working principle of the carbon screen, the importance of maintenance, maintenance steps and precautions, etc., are described in detail the maintenance work of the carbon screen.
The working principle of the 2. carbon screen The carbon screen, as the name suggests, is mainly used to separate impurities in coal and coal of different particle sizes. Its working principle mainly depends on the vibration of the screen surface and the design of the screen hole. When the coal passes through the screen surface, due to the vibration of the screen surface, the impurities in the coal and the coal with smaller particle size will be screened out, while the coal with larger particle size will continue to move forward, so as to realize the classification of coal.
The importance of 3. maintenance in the long-term use of carbon screen, due to the friction, impact and corrosion of coal and other factors, the screen surface will gradually wear, the screen hole will be blocked, resulting in a decline in screening efficiency, and even cause equipment failure. Therefore, regular maintenance of the carbon screen can effectively extend its service life, improve screening efficiency, reduce failure rate, and ensure the continuity and stability of production.
4. maintenance steps 1. check the screen surface first, you need to stop the machine to check the screen surface wear. For the screen surface with serious wear, it should be replaced in time. At the same time, but also to check whether the screen surface is flat, there is no convex or concave defects, if any, should be repaired.
2. Clean up the screen hole The blockage of the screen hole is one of the main factors affecting the screening efficiency. Therefore, it is necessary to clean the sieve holes regularly to ensure the smoothness of the sieve holes. When cleaning, special cleaning tools or high-pressure gas can be used for purging.
3. Check the vibration device vibration device is the core component of the carbon screen, its performance directly affects the screening effect. Therefore, it is necessary to regularly check the vibration frequency, amplitude and other parameters of the vibration device to ensure that it meets the requirements. At the same time, but also to check whether the connection parts of the vibration device is tight, whether there is a loose phenomenon.
4. Lubrication and maintenance The transmission parts and bearings of the carbon screen need regular lubrication and maintenance. The selection of lubricating oil should meet the equipment requirements and be replaced in accordance with the specified cycle. During lubrication, ensure the cleanliness of the lubricating oil and prevent impurities from entering the lubrication system.
5. Check the electrical system The electrical system is the power source of the carbon screen, and its stability and reliability are essential to the normal operation of the equipment. Therefore, it is necessary to regularly check whether the wiring of the electrical system is firm, whether the switch is flexible, and whether the motor is operating normally. At the same time, but also to do a good job of electrical system waterproof, dustproof and other protective measures.
5. precautions 1. Before maintenance, stop the machine and cut off the power supply to ensure that the equipment is in a safe state.
2. When cleaning the screen hole and checking the screen surface, protective gloves and glasses should be worn to avoid injury.
3. When replacing the screen surface and vibration device, the accessories matching the original equipment should be selected and installed according to the specified installation steps.
4. During lubrication and maintenance, ensure the cleanliness of the lubricating oil to avoid impurities entering the lubrication system.
5. When checking the electrical system, pay attention to safe use of electricity to avoid electric shock accidents.
6. conclusion The maintenance of carbon screen is an important measure to ensure its normal operation and prolong its service life. Through regular inspection and maintenance of the screen surface, screen holes, vibration devices, lubrication systems and electrical systems, the screening efficiency and service life of the carbon screen can be effectively improved, the failure rate can be reduced, and the continuity and stability of production can be ensured. Therefore, in actual work, we should attach great importance to the maintenance of the carbon screen to ensure the normal operation of the equipment.
