Wind distributing device controlled by wind pressure

Abstract

The invention relates to a wind distributing device controlled by wind pressure, belonging to the technical field of detection and regulation of wind distributing machines during threshing, redrying,production and processing in the tobacco production industry. The wind distributing device controlled by wind pressure comprises an upper box body, a middle box body, a lower box body, a feeder, a pressure sensor I, a pressure sensor I', a material throwing roll, a pressure sensor II, a pressure sensor II', a material conveying net belt, an adjusting valve I, a wind pipe I, a wind pipe II, a pressure sensor III, a pressure sensor III', an air regulating valve II and a material discharge delivery pipe. Wind pressure in three boxes of a wind distributing machine is detected through three pairs of pressure sensors. Additionally, signals are fed back to corresponding fan frequency converters. Therefore, the wind field in the wind distributing machine is uniform. Material is uniformly suspended. Material deviation, spirals and material accumulation do not occur. The best wind pressure effect is achieved. In the present stage, the wind distributing machine is prevented from being controlledby parameter control. Control is not flexible. There is an improvement space for wind distributing quality indices of products.

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
