An air separation device with air pressure control

Abstract

The invention relates to an air separation device controlled by air pressure, which belongs to the technical field of detection and regulation of air separation machines for leaf threshing and redrying production and processing in the tobacco production industry. The air separation device controlled by air pressure includes an upper box body, a middle box body, Lower box, feeder, pressure sensor Ⅰ, pressure sensor Ⅰ ， , throwing roller, pressure sensor Ⅱ, pressure sensor Ⅱ ， , conveying mesh belt, regulating valve Ⅰ, air pipe Ⅰ, air pipe Ⅱ, pressure sensor Ⅲ, pressure sensor Ⅲ ， , air regulating valve II, and discharge conveying pipe; the present invention respectively detects the wind pressure in the three boxes of the air sub-machine through three pairs of pressure sensors, and feeds back the signals to the corresponding fan inverters respectively, so that the air field in the air sub-machine is uniform and the material Suspension is uniform, without material deviation, vortex and material accumulation, to achieve the best air distribution effect. Avoid using parameters to control the air splitter at the present stage, the control is not flexible, and there is a large room for improvement of the product air split quality index.

Description

technical field [0001] The invention belongs to the technical field of detection and regulation of an air separator for leaf threshing and redrying production and processing in the tobacco production industry, and in particular relates to an air pressure-controlled air separator. Background technique [0002] The control of the existing air separator is to adjust the frequency of the air separator motor according to the parameters such as the large and medium slice rate of the material after the air separation, and the leaf stem. However, the result of the material detection has a delay, and the control parameters of the air separator are According to different level modules and experience parameter settings. Generally, when the processing module of this level is stable, the frequency of the motor is no longer adjusted, and the air volume and air pressure of the fan are constant. However, in the actual processing process, due to the different weights of the mixture of tobacc...

Problems solved by technology

Generally, when the processing module of this level is stable, the frequency of the motor is no longer adjusted, and the air volume and air pressure of the fan are constant. However, in the actual processing process, due to the different weights of the mixture of tobacco sheets, tobacco stems and leaves with stems, the suspension speed is different. Improper setting of the air guide door, supplementary air door, air inlet valve and upper air valve of the dust removal air pipe, the material conveying pipe of the air separator is easy to be blocked. It increasingly does not meet the requirements of factory lean management, product quality and equipment management
