LFD-227/229-Y Powder Impulse Flow Meter

Fresh alumina enters this system through a pneumatic chute. The material is divided into two paths by the distributor and enters the sand removal device respectively. After sand removal, it flows into the collector and enters the aggregate box, where slag is removed. The gas is led out from the exhaust port, and when the material accumulates to the material level, the switch controls the feeder to feed. The punch flow meter starts measuring, and the flow accumulator displays the instantaneous flow rate and cumulative flow rate. The flow rate can be set through a flow regulator according to actual production needs, and the feeder can be automatically adjusted. When the aggregate bin is empty, the level switch controls the feeder to automatically close. This process eliminates the influence of high-pressure air on the flow meter of the baffle. After being measured by the flow meter, the material enters the lower chute until it reaches the purification system. When there is a blockage in the current chute and the material accumulates to the discharge level, the material level switch controls the feeder to close, avoiding the material from piling up more and more in the lower chute, keeping the chute smooth, and ensuring effective and balanced production.

The multifunctional LFD-XXX-Y series metering control and processing system is designed specifically for the measurement of concentrated phase pneumatic conveying of aluminum oxide in electrolytic aluminum purification systems. Different types of punch flow meters are selected according to the flow rate.

1. This system has sand and slag removal functions to ensure smooth flow of the chute channel. By controlling, monitoring and alerting for blockages and shortages can be implemented to prevent equipment from running idle and causing resource waste.
2. On site, there are instantaneous and cumulative flow rates, and flow control can be adjusted according to actual production needs. Remote operation can also be achieved in the control room.
3. When there is no material in the upper chute, that is, when the material discharge port of the silo is not smooth; Send an alarm signal to remind the operator to handle it in a timely manner and control the feeder to automatically shut down, ensuring the accuracy of the material
Measurement. After the reply, the feeder will automatically start.
4. When the chute is blocked, an alarm signal is issued to remind the operator to handle it in a timely manner and control the feeder to automatically shut down, facilitating the operator's handling and ensuring accurate material measurement. reply
The rear feeder automatically starts.
5. This system is equipped with an emergency channel. In the event of a malfunction in the flow meter, the emergency channel will be opened to facilitate maintenance of the flow meter while ensuring production.
6. During calibration and maintenance of this system, the flow regulator box door does not need to be opened. It can be operated manually to prevent dust from entering and causing damage to the instrument.
7. This system is equipped with multiple windows, which can observe the operation of materials in the system at any time, in order to discover problems and solve them in a timely manner.
8. When the pipeline is completely sealed, it can measure oxidizing and reducing substances in a completely isolated dust pollution state from the atmosphere, and prevent environmental pollution.
