Heavy apron feeder is a common feeding device, with its strong impact resistance, wear and durability, long service life and other advantages, can be widely used in coal, cement, chemical industry, mining, metallurgy and other industries, so how to ensure its safe production and stable operation of equipment in normal use, reduce the damage rate of equipment, apron feeder Here are some general safety tips on apron feeder to give you the answer. 1. This procedure applies to heavy duty apron feeder.
Second, check before starting
1. Check whether the oil quantity and oil quality of the reducer meet the standard. If there is insufficient or deterioration, fill and change the oil in time. To lubricate the part with waste oil, it is necessary to ensure that the amount of waste oil is sufficient and the lubrication pipeline is smooth.
2. Oil is injected once per shift for each head and tail bearing, sprocket wheel and support wheel bearing.
3. Check whether bolts are loose and firm in time.
4. Check the tightness and consistency on both sides, and adjust in time if there is loosening or inconsistency in tightness.
5. Check whether the parts of the mechanism are in good condition. If there is damage, welding or crack, it should be dealt with in time.
Third, boot:
1. After receiving the central control boot command, the post shall conduct a comprehensive safety check, confirm the safety of the site, notify the central control boot, and both parties shall make a call record (including time, call content, and names of both parties).
2. Start the machine on site. Before starting the machine, the post must carry out safety check to confirm the safety before starting the machine.
3. During production, the switch on and off signal should be contacted accurately and operated according to the switch on and off sequence stipulated by the overall crushing system.
4. Check during operation
1. Check the temperature and temperature rise of bearings everywhere. Under normal circumstances, the temperature rise of bearings shall not exceed 30 ° C, and the maximum temperature shall not exceed 60 ° C.
2. Check the operation of the chain plate, especially if the link bolt is loose, if it is loose and firm, keep the chain tightness moderate, such as deviation is found in time through the tension device to adjust.
3. Check whether the support wheel and sprocket are flexible in rotation. If there are abnormal noises and faults during operation, the machine should be shut down for inspection and timely treatment.
4. Always pay attention to observe the display value of each instrument and instrument control panel during operation. If it is found that the value exceeds the specified range, stop the machine in time to find out the cause.
5, in the production process, the chain plate should always maintain a certain thickness of the material, generally should not be less than 500 mm, never allowed to unload directly to the chain plate in the unloaded state, so as to avoid stone impact damage to the chain plate.
6. When the bulk material is blocked, it should be handled according to the actual situation, and notify the next process in time, and it is not allowed to forcibly start.
Five, shutdown
Before stopping, there should be a certain thickness of stone on the apron feeder heavy plate before stopping, so as to avoid stone emptying and stone stopping during production.
The heavy plate feeder must ensure that there is enough stone on the chain plate at the bottom of the chute to stop, and it is forbidden to empty the chute to stop.
6. Troubleshooting:
When the discharge port of the plate feeder and the chamber plate feeder is stuck by a large block, the method of drilling and blasting should be used to remove the large block, or the crane should be used to lift the large block, and the large block should not be forced to use manpower to avoid collapsing stones.
Safety precautions should be taken when handling large blocks of material. One is to use the diving board across the hanging area, with the drill drilling blasting; The second is to use the head of the gun rod to process the charge, and to blast loose across the hanging area; Third, if the conditions can be used to lift out the large pieces of crane. Personnel are prohibited from entering the overhanging dangerous area.
7. Safety precautions
Wear labor protection articles according to regulations before starting work.
It is forbidden to work after drinking.
Check that the inspection route is free of obstacles to ensure that the inspection route is smooth and safe of apron feeder.
Check that safety facilities and lighting facilities are in good condition to ensure personal safety.
It is strictly forbidden to stand, stay or walk under the hanging objects and near the hoisting holes.
When you hear the power bell ring, immediately evacuate to a safe position.
