Product introduction
A-belt feed, also known as A-belt coal feeder, is a kind of raw coal feed equipment, which is that equipment in the clean coal production line. The modified machine has the advantages of stable operation, high speed, low noise and good explosion-proof performance, belongs to an environment-friendly product, has high efficiency, energy saving, low cost and large feeding capacity, can reach thousands of tons per hour, and is a common model. A belt feeder adopts the principle of belt conveyor. The conveying power is a combined stepless speed reducer motor. The belt speed can be adjusted manually or by frequency converter as required.
A belt feeder is a new type of product developed, which has the advantages of small operating power, light weight, large feeding amount, stable feeding amount, convenient adjustment, low noise, small amount of maintenance, and strong versatility of components, and can be used to replace the feeder currently in use. The invention overcomes the defects of the reciprocating type and vibrating type feeders which are widely used in the feeding system at present, changes the discontinuous feeding mode into the continuous feeding mode, changes the constant feeding amount into the dynamic continuous adjustable feeding amount according to the requirements of users, and enables the feeding system to better meet the requirements of high efficiency, energy saving and environmental protection.
How it works
The material in the storage bin enters the guide chute through the connecting section and falls on the belt a, and when the belt a is static, the material finally stops moving by internal friction,
When the driving roller starts to rotate under the drive of external power, the driving roller drives the rubber belt to move, the rubber belt drives the belt a on the rubber belt to move, the belt a drives the material on the belt a to be guided to the discharge hole, the belt a in operation turns to return after discharging at the discharge hole, and the material is continuously discharged from the discharge hole, thereby completing the feeding process; A secondary seal device is used for seal that material leaked from the gap between the material guide groove and the adhesive tape; To change the feeding amount, the speed of the output shaft can be changed by adjusting the speed regulating hand wheel of the planetary friction-type stepless speed changer of the tumbler, and the running speed (high or low) of the belt A can be changed, so as to change the feeding amount; to change the feeding amount, the speed of the motor can also be changed by selecting the frequency converter, so as to change the feeding amount. During the operation of belt a feeder, the main load of the system is supported by rolling bearings, so the operation resistance is small, the driving power required by the equipment is small, and the working life of each part of the system is long.
Product advantages
(1) Low operating power (coal feed rate 4400 t/H — 11 KW), low energy consumption and good operating economy;
(2) The feeding amount is large and stable, and the adjustment is convenient (manual or variable frequency stepless speed regulation);
(3) Stable operation, low noise and environmental protection;
(4) that abrasion is small, the maintenance quantity is small and the service life is long;
(5) The parts have strong universality and are easy to install and maintain;
(6) It can replace other types of existing feeders.
