Embodiment 1

[0070] An embodiment of the present disclosure provides an automatic control method for a powder feeding system, including:

[0071] like figure 2 As shown, the fluidization automatic adjustment of powder bin 1 is carried out,

[0072] Control the operation of the fluidizing device 5 arranged on the powder silo 1 according to the obtained powder silo wall pressure;

[0073] and / or, perform automatic adjustment of the pressure in the mixer 3,

[0074] According to the average value y of the pressure in the mixing chamber 31 of the mixer 3 and the set outlet pressure range [a, b] of the quantitative conveying device 2, it is adjusted to enter the mixing chamber 31 from the communication position of the wind phase pipeline 32 and the mixing chamber 31 air flow;

[0075] And / or, perform automatic adjustment of the delivery volume of the quantitative delivery device 2,

[0076] Determine the optimal powder flow monitoring system on the mixer 3 according to the working frequenc...

Embodiment 2

[0123] The above embodiment 1 provides an automatic control method for a powder feeding system, and correspondingly, this embodiment provides an automatic control system for a powder feeding system. The automatic control system provided in this embodiment can implement the automatic control method for the powder feeding system in Embodiment 1, and the system can be implemented by software, hardware or a combination of software and hardware. For example, the system may include integrated or separate functional modules or functional units to perform corresponding steps in each method of Embodiment 1. Since the evaluation system of this embodiment is basically similar to the method embodiment, the description process of this embodiment is relatively simple, and the relevant part may refer to the partial description of Embodiment 1, and the evaluation system of this embodiment is only schematic.

Abstract

The invention discloses an automatic control method and system for a powder feeding system, including automatic adjustment of powder silo fluidization, and controlling the operation of a fluidization device arranged on the powder silo according to the obtained powder silo wall pressure; and / or performing The pressure in the mixer is automatically adjusted. According to the average pressure y in the mixing chamber of the mixer and the set outlet pressure range [a, b] of the quantitative conveying equipment, the pressure entering the mixing chamber from the connecting position of the air phase pipeline and the mixing chamber is adjusted. and / or automatically adjust the conveying volume of the quantitative conveying equipment, determine the optimal powder flow monitoring system on the mixer according to the working frequency of the quantitative conveying equipment, and monitor the obtained powder according to the optimal powder flow monitoring system Flow Q and preset powder flow Q 设定 , adjust the working frequency of the quantitative conveying equipment.

Description

technical field [0001] The invention relates to an automatic control method and system for a powder feeding system, belonging to the field of powder, in particular to the field of quantitative powder conveying. Background technique [0002] The conventional powder feeding system usually consists of three parts: powder silo, quantitative conveying equipment and mixer. The powder silo is used to store the powder. In order to ensure the fluidity of the powder, a gas fluidization or mechanical stirring device is usually provided. Quantitative conveying equipment is used to control the conveying rate of powder, and at the same time play the role of blocking the 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 conveying rate is only controlled by adjusting the motor frequency of the quantitative conveying equipment...
