How to install the comprehensive protection device of the mining belt conveyor and its supporting eq

Belt conveyor is the abbreviation of belt conveyor, there are fixed and mobile, simple structure, high efficiency. Continuous conveying machinery with flexible conveyor belt as material bearing and traction components. The characteristics of the mining belt conveyor protection device are suitable for the comprehensive protection and control of the belt conveyor in the mine with the highest gas and coal dust.

It can also be used for centralized control and protection of chain machines.

The comprehensive protection instrument of the mining belt conveyor is designed according to the requirements of the Ministry of Coal on improving the protection of the underground belt conveyor, after a large number of underground field investigations and tests, the existing comprehensive protection device of the belt conveyor has been optimized and improved, and a new type of intelligent single-chip microcomputer with high reliability has been listened to, and a large number of user feedback has been listened to, so that the intelligence, reliability, advancement and ease of operation of this product have been greatly improved compared with similar products.

The main engine of the belt comprehensive protection device is composed of an explosion-proof cavity and an intrinsically safe shell, and there are intrinsically safe actuator power supply, intrinsically safe control unit, display operation unit and various intrinsically safe sensors inside China Coal.

The mining belt conveyor protection device is designed by using dual bus control mode, and the network communication technology is used to design the ALI11 that can monitor and control the operation and fault state of the belt conveyor in the underground coal mine on the ground; The advancedness, reliability, ease of operation, and energy saving of the belt conveyor comprehensive insurance have been greatly improved compared with the comprehensive protection of similar belt conveyors.

The power supply actuator is flameproof and intrinsically safe, with a rectangular shape and a 36V (127V) power supply introduction and relay control contact outlet at the left end; The right end is the outlet of the over-temperature automatic sprinkler control point; The upper right is the 12V 1A intrinsically safe power supply and control signal outlet.

4. What are the brands of the eight major protection devices of the belt conveyor?

1.Overload protection: An overload protection device installed to prevent the main power supply line from overheating and damage to the protector due to overload.

2.Overcurrent protection: When the current exceeds the set current, the device will automatically power off to protect the device.

3.Two-way rope switch protection: It is a kind of protection device for the on-site emergency shutdown of the belt conveyor.

4.Speed switch protection: When an electric shock occurs, the neutral point is offset to generate a voltage to the ground, so as to cut off the power supply.

5.Longitudinal tear protection: Using the principle of electromagnetic induction, the receiver receives the electromagnetic pulse signal generated by the generator through the sensing coil.

6.Two-stage deviation switch protection: according to the degree of deviation of the belt, it can realize automatic alarm and shutdown.

7.Coal flow signal protection: It can provide alarm signals such as belt coal flow, coal breakage, coal blockage, and chain breakage.

8.Coal plugging switch protection: use the change of the contact opening and closing in the coal plugging switch to judge the working condition of the protection equipment, and take timely measures to achieve the purpose of safety protection.
