Sintering raw material air permeability detector

The utility model provides a sintering raw material air permeability detector. The sintering raw material air permeability detector comprises air source equipment, a pressure reducing valve, a regulating valve a, a regulating valve b, a pressure transmitter a, a temperature transmitter, a pressure transmitter b, an air chamber and an instrument panel and is characterized by further comprising a metal pipe flowmeter and a hopper; the air source equipment is communicated with the pressure reducing valve; the pressure reducing valve is communicated with the regulating valves a and b; the hopper is communicated with the air chamber at the lower part of the hopper; the metal pipe flowmeter is mounted on a pipeline through which the air chamber is communicated with the air source equipment; the pressure transmitter a, the pressure transmitter b and the temperature transmitter are connected between the pipeline and the instrument panel. The sintering raw material air permeability detector is also characterized in that the hopper takes the shape of a square cylinder with a widened contact surface and is designed according to a steel mill universal hopper by an equal proportion. The sintering raw material air permeability detector has the advantages that data inaccuracy caused by an edge effect during the detection of a laboratory device is effectively avoided, so that an accurate empirical data support is provided for actual application; the error between the measurement value and the actual value of the air permeability of a sintering raw material is small, and the measurement precision is high.
