I. Scraper conveyor
1. Working principle
Scraper conveyor is a kind of continuous conveying equipment, mainly composed of frame, chain, scraper, driving device and pallet. Its working principle is to drive the chain to rotate through the electric motor, the scraper is fixed on the chain, when the chain rotates, the scraper shovels up and pushes the material to move forward, realizing the continuous conveying of the material.
2. Precautions in the process of using
Choose appropriate loading capacity: follow the rated capacity of the Scraper conveyor and avoid overloading, so as not to affect the performance and service life of the equipment.
Check the status of the equipment: Before using, check the main parts such as chain, scraper, transmission device, etc. to make sure they are intact.
Pay attention to material uniformity: uniform distribution of materials is very important, and overloading on one side should be avoided as much as possible.
Supervise the operation status: Continuously monitor the sound, vibration and temperature changes during the operation, and recognize the abnormal situation in time.
Do safety protection: During operation, non-staff should stay away from the equipment and wear appropriate personal protective equipment.
3. Daily maintenance
Lubrication and maintenance: Regularly lubricate the chain, bearings and other moving parts to reduce wear and tear.
Clean up the equipment: Clean up the material residue and keep the equipment clean, especially the chain and scraper part.
Check fasteners: regularly check whether the connecting parts are loose and tighten them in time to prevent the failure brought by loose equipment.
Regularly check the wear and tear: monitor the wear and tear of the scraper and chain, especially the tension of the chain, and replace the damaged parts in time.
Record maintenance logs: Form regular maintenance records to facilitate tracking the maintenance history and performance status of the equipment.
Second, coal conveyor
1. Working Principle
coal conveyor is mainly used for transporting coal and other granular materials, through the movement of motor-driven belt conveyor or chain, the coal will be transported along the track of the conveyor to the designated position. There are many kinds of conveyors, such as belt conveyor, Scraper conveyor and so on.
2. Precautions during use
Reasonable installation: Make sure the installation of the coal conveyor is in accordance with the manufacturer's recommendations, including the angle of inclination, levelness and support structure.
Control the conveying speed: According to the nature of coal and transportation distance, control the conveying speed reasonably to avoid material breakage or accumulation.
Keep clean: Ensure the area around the coal conveyor is clean to prevent coal dust from accumulating and affecting the normal operation of the equipment.
Monitor the load: Do not exceed the rated load of the equipment to prevent the equipment from being damaged due to the accumulation of too much material.
Troubleshooting in time: If you find abnormal noise and overheating phenomenon during operation, you should stop the machine immediately for inspection.
3. Daily maintenance
Adjustment and cleaning: Regularly adjust the tension of the conveyor belt to ensure that it will not slide during operation. At the same time, clean the tape and roller of the conveyor belt to prevent materials from sticking.
Check the electrical system: Check the motor and transmission system regularly to make sure all electrical connectors are intact and wires are not damaged.
Replacement of worn parts: Replace worn rollers, pulleys and belts in time to maintain conveying efficiency.
Lubrication Maintenance: Regularly lubricate all moving parts (such as bearings and reducers) to ensure smooth operation.
Record usage: Keep records of equipment work to facilitate later analysis and decision-making and enhance maintenance effectiveness.
With the above information, it can be seen that Scraper conveyor and coal conveyor have different working principles, but the precautions to be taken during use and routine maintenance have similarities. Ensuring that these standards are followed in use and maintenance can improve the efficiency of the equipment, extend its service life, and reduce the risk of failure.
