Belt Type Coal Feeder

Overview of the belt type coal feeder

The power of the belt-type coal feeder adopts the motor cycloidal pin wheel reducer, which has a compact structure, stable operation, a large speed regulation range, and can realize stepless speed regulation. Annular rubber belt transmission: the annular rubber belt can adjust the tightness and deviation of the belt through the adjustment of the tensioning device of the reversing expansion wheel because of the use of the annular mechanism to realize continuous coal feeding, which is different from the one-way coal feeding of the K-type reciprocating coal feeder and greatly improves work efficiency. The use of a 16Mn alloy cast chain link as the working surface also improves the service life of the equipment, and with a nylon rod pin connection, this structure has a strong impact resistance. Large feeding range (0~500mm) This equipment is widely used in the coal feed of the raw coal end. Due to its high production efficiency and stable working performance, its market share is very high.

The GLD series A belt coal machine is widely used in coal, metallurgy, electric power, and other industries of various silo feeding. For the rotation of continuous feeding mode, the user in the production can be adjusted (manual adjustment or hydraulic cylinder adjustment) without stopping the machine according to the need. A belt coal machine makes the feeding system more efficient, energy-saving, meets environmental protection requirements, and is more durable than the belt feeder.

 In addition to the production of the GLD series standard armor belt coal machines, our company also produces non-standard, extended-type, and other armor belt coal machines.

The main features of the belt type coal feeder

1. Large feeding capacity, 200∽4000t/h, stepless speed regulation, continuously adjustable according to specific working conditions (manual or electrical stepless speed regulation);

The annular belt is a new type of belt with a special steel core mesh conveyor, which is made of 16MN alloy or 45# steel, which has the characteristics of high braiding density, wear resistance, impact resistance, strong penetration resistance, and good elasticity and has the functions of anti-deviation and anti-skidding; it overcomes the old-fashioned belt with easy coal trapping, which leads to the separation of the belt from the belt, slippage, belt breakage, etc., resulting in high maintenance labor intensity and high cost; The lining tape adopts an anti-deviation structure, and a trapezoidal rib is added in the middle of the annular belt, which has a strong function of anti-deviation, which greatly overcomes the problem of belt deviation in the past.

2. When the equipment is overhauled, the electro-hydraulic or manual plate gate can automatically cut off the coal flow in the silo.

3. Detachable connection between each component, light weight, easy installation and maintenance, and long service life;

4. The joint of the new belt feeder adopts a special lap buckle method, which does not need to be disassembled and installed as a whole, which overcomes the problems of high labor intensity, long time, and affecting production of the old-fashioned belt replacement;

5. It can replace the vibrating feeder, reciprocating feeder, and old-fashioned belt feeder, and the original installation foundation can be basically unchanged;

The speed regulation mode can adopt manual stepless speed change and frequency conversion speed regulation, which can realize on-site and remote centralized control, which is convenient for remote monitoring and speed regulation.

The working principle of the belt type coal feeder

The material in the silo enters the guide groove through the connecting section and falls on the first belt, and when the first belt is stationary, the material finally stops moving by internal friction and forms a static accumulation at a certain angle at the discharge port. When the driving drum starts to rotate under the drive of the driving device, the belt is driven to move, the belt on the belt is driven to move, the belt is driven to guide the material on it to the discharge port, the running belt is turned to the return stroke after the discharge port, and the material is continuously discharged from the discharge port so as to complete the feeding process; The sealing device provides a seal for the material leaking from the gap between the guide trough and the tape. Changing the feeding amount can be achieved by adjusting the speed-regulating handwheel of the reducer to change the speed of the output shaft and the size of the running speed of the belt, or by adjusting the frequency of the inverter and changing the speed of the motor.

Installation instructions of the belt type coal feeder

The conveyor can be installed separately on site or as a whole. When the split is installed, the funnel frame is installed at the mouth of the coal bunker first, and then the box is installed, and then other components such as the base frame are installed. During the overall installation, the funnel frame is installed at the mouth of the coal bunker, and then all the other components are assembled, and the overall hoisting and connection section are connected with bolts.

Product features of belt type coal feeder
