The comprehensive protection of belt conveyor is designed by the Ministry of Coal for the protection of underground belt conveyors. The comprehensive protection device of the belt conveyor generally has two control modes: centralized control and single machine control. When multiple units are centrally controlled, it has the function of interlocking and the function of extending the sequence of starting against the coal flow, and the extension time is 10 seconds and 5 seconds, and the centralized control cannot exceed eight units.

When manually controlled, it is equipped with a start-stop sensor to realize the delay sequence start and stop. The inherent functions of Shandong Zhongmei Belt Conveyor Comprehensive Insurance: starting delay, voice alarm, fault self-locking, fault stopping, system status display, and intercom function.

The belt conveyor comprehensive protection is composed of an explosion-proof cavity and an intrinsically safe shell, which is used as a comprehensive protection for the belt conveyor, such as skidding, low speed, over-temperature, coal stacking, deviation smoke, etc., and for centralized control and dot communication between multiple belt systems, and is equipped with an independent over-temperature automatic sprinkler device.

Technical parameters of comprehensive protection of belt conveyor:

Overcurrent protection setting value.

Centralized control signal less than 5mA;

Rated input voltage: AC127V or 36V;

Maximum allowable voltage: AC140V or 40V;

Intrinsically safe output maximum open-circuit voltage: DC12V;

Relay output contact capacity; ac250v 5a；

Intrinsically safe output maximum short-circuit current: DC400mA;

Intrinsically safe output external allowable branch inductance: 1MH km;

Maximum open-circuit voltage of intrinsically safe circuit: +12V short-circuit current;

Intrinsically safe output external allowable subcapacitance: 0 1 F km;

Working voltage: 5V, current 70mA, output power less than 2W;

The maximum length of the cable ALI11 connected between each sensor and the host shall not exceed 1500m.

Belt conveyor comprehensive protection combination parameters: 12V 350mA (smoke sensor, speed sensor, temperature sensor);

The connection between the sensor and the host is 1500 meters, the connection between the host is not more than 1500 meters, and the capacitance and inductance of the division are 1mh;

Anti-skid, temperature, smoke, and belt-controlled sensors are active accessories, with a rated voltage of 12V, a quiescent current of less than 115mA, and a maximum action current of less than 150mA, and the rest of the sensors are passive devices, and the maximum working current is 5mA when acting;

If it is used in the slitting production line, there is no national standard and industry standard. Belt tensioning machines are used to compress steel plates on slitting lines, resulting in counter-tension.

The belt conveyor used in coal mine is generally GB10595 and MT821

1. The belt conveyor for coal mine is generally GB10595 and MT821.

2. Belt conveyor is the abbreviation of belt conveyor, with fixed and mobile type, simple structure and high efficiency. Continuous conveying machinery with flexible conveyor belt as material bearing and traction components. An unended conveyor belt surrounds the drive pulley and the reversing pulley.

The upper and lower branches between the two rollers are each supported by a number of idlers. The material is placed on the upper branch, and the friction between the drive pulley and the belt is used to pull the conveyor belt and the material to run. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions, and can also be used for assembly lines for certain process operations.

The structure is simple, the work is stable and reliable, the adaptability to materials is strong, the conveying capacity is large, the power consumption is small, and the application is wide.

1] The characteristics of the belt conveyor: The belt conveyor can convey a wide variety of materials, not only can transport all kinds of bulk materials, but also can convey a variety of cartons, packaging bags and other pieces of goods with a small single weight, and has a wide range of uses. The structure is diverse, there are trough belt conveyors, flat belt conveyors, climbing belt conveyors, tilt belt conveyors, turning belt conveyors and other forms, and the conveyor belt can also add push plates, side baffles, skirts and other accessories, which can meet various process requirements.

The conveyor belt is made of rubber, canvas, PVC, PU and other materials, which are not only used for the transportation of ordinary materials, but also meet the transportation of materials with special requirements such as oil resistance, corrosion resistance, and anti-static. The special food-grade conveyor belt is used to meet the requirements of food, pharmaceutical, daily chemical and other industries. The conveying is smooth, and there is no relative movement between the material and the conveyor belt, which can avoid damage to the conveyed goods.

Compared with other conveyors, the noise is smaller, and it is suitable for occasions where the working environment is relatively quiet. Simple structure and easy maintenance; Low energy consumption and low cost of use.
