Introduce of belt conveyor protection features in mine

HONGKOU, China - June 20, 2013 - PRLog -- Introduce of belt conveyor protection features in mine

Belt Conveyor, also known as belt conveyors, belt friction drive principle according to which campaign for conveying bulk density 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 at ambient temperature -20 ℃ to 40 ℃ range, sent the material temperature is less than 60 ℃. Its captain and assembly forms can be determined according to user requirements, transmission can be electric drum can also be used with the drive rack drives.

Belt Conveyor Protection Features:

(A) mine belt conveyor speed protection. If the conveyor malfunction, such as electric motors burned, mechanical transmission part is damaged, pull off a belt or chain, belt slippage, mounted on the conveyor passive mechanical accident sensors magnetic switch can not be closed or not closed at normal speed, Then the control system will be inverse characteristics after a certain delay, speed protection circuit works, so that the operative part of moves to cut off the motor supply, in order to avoid accidents to expand.

(2) mine conveyor belt temperature protection. Friction roller and belt conveyor to a temperature gauge, close to the rollers mounted over-temperature detection device emits signals, the receiver receives a signal, after 3s delay, so that the operative part of moves to cut off the motor power supply, automatic conveyor stall, play temperature protection.

(3) mining of coal belt conveyor bit protected under the nose. If a conveyor operation or an accident can not be blocked or gangue coal bin is full due to reasons such parking heap of coal under the nose, then the corresponding position of the coal and coal contacting position sensor, coal bit immediate action to protect the circuit, so that after a conveyor stop immediately. Then continue to the coal face, behind the conveyor tail will occur sequentially one by one pile of coal, and make appropriate after a stop until the loader automatically stop running.

(4) mine belt conveyor coal bin coal level protection. Coal Bunker set high and low two bits of coal electrodes, due to no empty coal bunker can not put coal, the coal will gradually be increased, when coal rose to high electrode, coal-bit protected action, from the first stage belt conveyor start each conveyor tail pile of coal in turn due to parking.

(5) mine belt conveyor emergency stop atresia. Lower right corner of the front of the control box with emergency locking switch, use the switch left and right rotation, can this station or reception conveyor implement emergency lockout.

(6) mine belt conveyor deviation protection. If the belt during operation deviation phenomenon occurs, then the deviation from the normal operation of the track belt conveyor mounted on the edge of the next deviation sensing rod call back and immediately send alarm signals. To maintain the duration of the alarm signal according to need in the range of 3-30s it is set in advance. During an alarm if they can take timely measures to relieve the deviation, the conveyor can continue normal operation.

(7) mine belt conveyor at any point midway stop protection. If at any point along the conveyor needs to stop, they have to switch to the appropriate position in the stop position, the belt conveyor will stop immediately. Need to open, the first switch is reset, and then press the switch to signal to the signal.

(8) mine belt conveyor smoke protection. When the roadway due to friction and other causes smog belt occurs, smoke hanging in the roadway sensors sound an alarm function, and after 3s delay, the role of the protection circuit cut off the motor supply, play smoke protection.
