Problems solved by technology
Due to the long-distance high-pressure transportation, both of them require a relatively large material intermediate warehouse for material measurement and prevention of material return. It is difficult to achieve continuous transportation of a single device, and it is impossible to control the amount of material conveyed.

The invention discloses a powder / granule conveying device with the adjustable conveying amount. The powder / granule conveying device with the adjustable conveying amount consists of a Venturi feeder, a check valve, a pressure reducing valve, a proportional adjusting solenoid valve, a negative pressure meter, a wind material measurement sensor and a controller, wherein a feeding opening of a feeding tube of the Venturi feeder is of a bent structure; the check valve and the negative pressure meter are successively arranged between the bent position of the feeding tube and a Venturi tube of the Venturi feeder; an air spraying branch tube of which the direction is the same as that of the feeding tube is arranged at the bent position of the feeding tube; the pressure reducing valve and the proportional adjusting solenoid valve are successively arranged on the air spraying branch tube in the air feeding direction; the wind material measurement sensor is arranged at a discharging opening of the Venturi tube; and the proportional adjusting solenoid valve, the negative pressure meter and the wind material measurement sensor are connected with the controller through cables. The powder / granule conveying device with adjustable conveying amount has the advantages of simple structure, maintenance easiness and production safety, and can adjustably, continuously and efficiently convey powder / granules by a long distance.
Description
technical field [0001] The invention relates to the field of pneumatic conveying of powder materials, in particular to a powder / grain conveying device with adjustable conveying volume. Background technique [0002] At present, common powder / granule pneumatic conveying devices are mainly divided into suction-type pneumatic conveying systems and pressure-feeding pneumatic conveying systems. The former installs air source equipment at the end of the system. When the fan or compressor is running, a negative pressure is formed in the entire system, and the material is sucked into the delivery pipeline by the pressure difference between the inside and outside of the pipeline; while the latter installs the air source equipment in the system. At the feed end, when the material enters the conveying system, it is pressed by the power from the air source and advances along the conveying pipeline. Due to the long-distance high-pressure transportation, both of them require a relatively ...
