Online monitoring of material flow switch

1Product Introduction

Online monitoring of material flow switchIt is based on the physical principle of Doppler effect and can be installed in pipelines, conveyor belts, feeding baffles, bucket elevators, chutes, wind conveyors, vibration troughs or similar conveying facilities for material flow/Detection of no material flow. This device can detect flow problems during the transportation or feeding process of powder, debris, small spherical, granular materials in advance，Helps to avoid various serious problems caused by pipeline blockage, material loss, or other technical issues in the system.

Application fields:The feed industry, glass industry, synthetic materials industry, construction industry, metallurgical industry, textile industry, ceramic industry, pharmaceutical industry, sewage treatment, chemical industry, power industry, environmental protection industry, food industry, rubber industry, etc.

Typical applications:

Pneumatic chute cement flow detection;

Monitor the transportation of raw material preheaters in cement plants;

Monitor the flow of free fall feed;

Monitoring of secondary fuel flow in gas rising pipelines;

Monitor the feeding situation of the spiral feeder in the gypsum plant;

Measurement of coal powder flow during blast furnace injection;

Free fall sugar beet pulp dust flow monitoring, etc.

IIworking principle

Online monitoring of material flow switch，Based on the principle of microwave Doppler, monitor coal powder concentration and pipe blockage. During the transmission and reception of microwaves, the transmitted microwaves pass through the measured medium and cause losses, which are proportional to the concentration of the measured medium; Due to the flow velocity of the measured medium, there is a Doppler shift between the transmitted and received waves. The greater the microwave loss, the higher the coal powder concentration; So the calculation of the medium flow rate automatically compensates for the influence of flow rate on concentration.
