Reciprocating feeder (Coal Safety Certificate No.: C) is used in coal mines, dressing In the coal plant, the reciprocating feeder unloads raw coal or clean coal evenly from the coal bunker and coal storage hopper, and transfers it to the transportation equipment. The reciprocating feeder or directly discharges it to the screening equipment or other coal preparation equipment. superior.
: >Structure of reciprocating feeder
The reciprocating feeder is mainly composed of a bin funnel, a box, a gate, a bottom plate, a roller, a driving device, etc.
: >Working Principle of Reciprocating Feeder
The rollers in the reciprocating feeder are used to support the bottom plate. The bottom plate is driven by the driving device and makes regular reciprocating linear motion on the rollers. The movement of the bottom plate of the feeder along the direction of coal flow is called forward movement, and the movement of the bottom plate against the direction of coal flow is called retrograde movement. When the bottom plate of the reciprocating feeder moves forward, the coal in the coal bunker and the coal feeder box is transported to the front end of the box. When the bottom plate moves backward, the coal in the box is blocked by the inclined plate at the rear of the box. There is a gap between the bottom plate and the coal. Without relative sliding, the coal at the front end of the box falls on its own, and the reciprocating feeder achieves continuous and even feeding due to the reciprocating motion of the bottom plate.
: >Installation and use of reciprocating feeder
The reciprocating feeder is fixedly installed under the storage port. Before installation, the horizontal position of the reciprocating feeder needs to be determined and the frame Tighten it with the warehouse mouth with screws, and then place the transmission platform in the correct position. Weld the frame, frame, and transmission platform firmly. Align the reducer and motor for installation, adjust them appropriately, and tighten them with screws.
.After the reciprocating feeder is installed in place, start the motor without load to make the reciprocating feeder run without load. When no abnormality is found within minutes of idling, stop and check the temperature rise of the motor and reducer. If everything is normal, check and tighten the relevant bolts and nuts again, then restart and slowly open the coal bunker to make the coal flow flow from small to small. Enter the reciprocating feeder to the maximum, so that the reciprocating feeder can be put into normal operation.
.When adjusting the productivity according to the unloading requirements, pull out the pin of the crank part, loosen the nut, and rotate the position of the crank shell. Select fixed, insert the pin, connect the crank and crank shell, and tighten the pin and nut, and drive again after adjustment is completed.
