Abstract

The invention discloses an automatic control method and system for a powder feeding system. The method comprises the steps: the fluidization automatic adjustment of a powder bin is carried out, and the operation of a fluidizing device disposed on the powder bin is controlled according to the obtained wall surface pressure of the powder bin; and / or the pressure in a mixer is automatically adjusted, and the air flow entering a mixing chamber from the communicating position of an air phase pipeline and the mixing chamber is adjusted according to an average pressure value y in the mixing chamber of the mixer and the set outlet pressure range [a, b] of quantitative conveying equipment; and / or the conveying capacity of the quantitative conveying equipment is automatically adjusted, an optimal powder flow monitoring system on the mixer is determined according to the working frequency of the quantitative conveying equipment, and the working frequency of the quantitative conveying equipment is adjusted according to the powder flow Q monitored by the optimal powder flow monitoring system and the preset powder flow Q setting.

Description

technical field [0001] The invention relates to an automatic control method and system for a powder feeding system, which belongs to the field of powder, in particular to the field of powder quantitative delivery. Background technique [0002] A conventional powder feeding system usually consists of three parts: a powder bin, a quantitative conveying device and a mixer. Among them, the powder bin is used to store the powder. In order to ensure the fluidity of the powder, it is usually equipped with a gas fluidization or mechanical stirring device. Quantitative conveying equipment is used to control the conveying rate of powder, and at the same time, it plays the role of blocking pressure difference. Common conveying equipment includes air lock valve, impeller powder feeder, etc. The mixer is used for mixing powder and conveying air. [0003] When the general equipment is running, the powder delivery rate is only controlled by adjusting the motor frequency of the quantitati...
