Mine belt conveyor
Belt Conveyor , also known as belt conveyors, conveyor belt according to the friction drive principle and exercise , for conveying bulk density of less than 1.67 / t / cubic meter, easy to dig a powder, granular, small block of low- abrasive materials and bagged materials such as coal , gravel , sand , cement , fertilizer , food and so on.Belt conveyor in the ambient temperature range -20 ℃ to +40 ℃ use , sent the material temperature is less than 60 ℃. Its captain and assembly forms can be determined according to user requirements ,
power transmission roller can also be used with a driving device frame .Belt Conveyor Protection Features:( 1 ) Mining protective belt conveyor speed. If the conveyor malfunction , such as motor burned, damaged mechanical transmission parts , belt or chain to pull off , belt slippage , accidents sensor is mounted on the conveyor passive parts of the magnetic switch can not be closed or not closed at normal speed , then the control system will be inverse time characteristics after a certain delay , the speed protection circuit works , so the operative part of the action , cutting off the motor power supply in order to avoid accidents expand.( 2 ) mine conveyor belt temperature protection . Belt conveyor roller and friction when its temperature gauge , close detection device installed in the drum over-temperature signal is issued after the receiver receives the signal, after 3s delay, so that the operative part of the action , cutting off the motor power supply, automatic conveyor stopped, the temperature play a protective role.( 3 ) mine protection under the coal belt conveyor head position . If a conveyor or an accident can not operate due to obstruction or gangue and coal bunker full stop under the heap of coal and other reasons make the nose , the corresponding position of coal and coal -contact position sensor , coal bit immediate action to protect the circuit , so that the a conveyor stop immediately . Then continue to the coal face , behind the conveyor tail will occur followed by Taiwan pile of coal , and make appropriate after a stop until it automatically makes loader stopped running.( 4 ) protecting mine coal bunker coal belt conveyor bit . Coal Bunker set the level of the two electrodes coal bit , coal bunker is not empty when due without caving coal will gradually be increased, when the level rises to the upper electrode of coal , coal -bit protected action, from the beginning of the first sets of belt conveyor each conveyor tail due to the heap of coal in order to stop.( 5 ) mine belt conveyor emergency stop atresia. In the lower right corner of the front of the control box with emergency stop latching switch , use the left and right of the rotary switch , latching emergency stop can be implemented on this station or reception conveyor.( 6 ) mine conveyor belt deviation protection.
If the deviation phenomenon conveyor happened during the run , then the deviation from the normal operation of the belt edge of the track deviation sensor mounted on the side of the conveyor lever to pour and an alarm signal immediately. Alarm signal to maintain the length of time may need to pre- set at the 3-30s range. During the alarm if they can take timely measures to lift the deviation, the conveyor can continue normal operation.( 7 ) mine conveyor belt at any point midway stop protection. If at any point along the conveyor need to stop , they have to switch to the corresponding position in the stop position, the belt conveyor will stop immediately . Need to re- open, the first switch is reset , and then press the switch signal to the signal .( 8 ) mine protection belt conveyor smoke. When the roadway due to other causes smog belt friction occurs, smoke hanging in the roadway sensors play an alarm sound , and after 3s delay protection circuit action , cut off the motor power play smoke protection.
