Weighing Coal Feeder

Introduction to weighing coal feeder

The weighing coal feeder is used in coal mines and coal preparation plants to evenly discharge raw coal or refined coal from coal bunkers and coal storage funnels, transfer them to transportation equipment, or directly unload them to screening equipment or other coal preparation equipment. Achieve uniform feeding of bulk materials such as ore, sand, coal, and grain. The feeding chute of this series feeder is made of linear reciprocating motion by the driving device through the crank connecting rod device. When the feed chute moves forward, the material is removed by the action of inertia force and friction force, and the material in the hopper falls at this time so that it cannot retreat and is unloaded at the front end. The transmission device of this series feeder is suspended, which can be directly arranged under the hopper and is easy to install.

Feed amount adjustment method of the weighing coal feeder 

The feed rate can be controlled by changing the opening of the fan-shaped adjustment valve to control the thickness of the material layer.

Installation and use of the weighing coal feeder

1. The reciprocating feeder is fixed and installed under the storage silo. Before installation, it is necessary to determine the horizontal position, fasten the frame and the bin with bolts, and then place the transmission platform in the correct position. The H-shaped frame and the frame are welded firmly, and the reducer and the motor are aligned and installed, adjusted appropriately, and fastened with bolts.

2. After the feeder is installed in place, the motor is started with no load to make the feeder run without load. If everything is normal, check and tighten the relevant bolts and nuts, then restart and slowly open the coal bunker so that the coal flow enters the feeder from small to large and the feeder is put into normal operation.

3. When adjusting the productivity according to the unloading requirements, pull out the crank part of the boat, loosen the nut, rotate the position of the crank shell "1, 2, 3, 4" to select and fix, insert the pin, connect the crank and the crank shell, fasten the pin and nut, and then start after adjustment.

The working principle of the weighing coal feeder

The weighing and feeding system is a material handling and loading system that integrates multi-point batching and loading equipment into one continuous weighing and metering system and controls the flow rate. The weighing and control process is continuous and automatic.

When the material from the user's silo or other feeding equipment conveys the belt through the feeder, the weighing device installed at the bottom of the belt will detect its weight (load signal), and at the same time, the speed sensor installed on the belt reversing drum shaft will monitor the speed of the belt (speed signal), and the load signal and speed signal will be transmitted to the weighing controller for processing, and the flow, speed, accumulation, and other data will be calculated. The data is transmitted to the main controller through the communication link between the weighing controller and the main controller, and the main controller comprehensively analyzes and processes the uploaded data and user setting information and issues the corresponding control instructions according to the processing results to control the system.

The operating conditions of each piece of equipment.

The intrinsically safe touch screen installed on the main control panel is a human-computer interaction control platform, and the user needs to set the corresponding parameters through the touch screen operation interface, the parameter interface, and the purpose expected to be achieved.

Users can set and modify the key parameters, flow parameters, control parameters, material flow, target loading capacity, and other parameters of the weighing feeder through the humanized man-machine interface of the remote-control center host computer and the nearby intrinsically safe main controller, control and adjust the start-stop and running speed of the weighing feeder, query the system operation status, and read the system operation data.
