Online blowing dust removal system and control method thereof

Abstract

The invention discloses an online blowing dust removal system. The online blowing dust removal system comprises a foreign matter removal machine bin, a screen arranged above the foreign matter removalmachine bin and used for screening dust and blades, a dust removal device arranged above the screen and used for dust absorption, a movable blowing device used for blowing the screen downwards, an adjusting device used for adjusting the dust absorption strength of the dust removal device, a detection device used for detecting the inner pressure of the foreign matter removal machine bin and a control device. The blowing device, the detection device and the adjusting device are connected with the control device. The control device is used for receiving pressure signals of the detection device,used for controlling adjusting operation of the adjusting device and used for controlling moving and blowing of the blowing device. By means of the system, the phenomenon that the dust removal screenis blocked can be effectively reduced, the device dust removal effect can be improved, the impurity removal effect of the foreign matter removal machine bin can be improved, and the online blowing dust removal system is simple in device structure and convenient to use and can be used and popularized; and in addition, the invention provides a control method applied to the above online blowing dustremoval system.

Description

technical field [0001] The invention relates to the technical field of dust removal, and more specifically relates to an online purging and dust removal system. In addition, it also relates to a control method applied to the above online purging and dust removal system. Background technique [0002] In the tobacco industry, it is necessary to use a foreign object removal machine to remove non-tobacco impurities in tobacco. Its working principle is: when the material passes through the camera viewing area, the light illuminates the material, and the camera can detect the color, shape and texture of the material. At the same time, High-speed image processing cards and software programs can distinguish debris that does not conform to the sorting color table, so the camera imaging effect is very important. The foreign matter rejecting machine generally uses transparent glass to isolate the material, so the cleanliness of the transparent glass directly affects the removal effect...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there is a large amount of dust accumulated in the reject chamber of the foreign body rejecting machine, and the visibility of the light-transmitting glass is low, which will also lead to high labor intensity for employees to maintain the foreign matter rejecting machine, and due to the large dust in the working environment, the health and safety of employees cannot be guaranteed. Guaranteed

The reason for the poor dust removal effect of the foreign body removal machine is that a large amount of tobacco leaves adhere to the surface of the dust removal screen during the production process, causing the dust removal screen to be blocked, making it impossible for the dust to be discharged in time, resulting in a large amount of dust accumulation in the removal bin and low visibility of the transparent glass. As a result, the removal effect of the foreign matter rejecting machine is low, and when non-tobacco debris is found in the subsequent process, it needs to be stopped for picking, which will eventually affect the stability and continuity of tobacco production and cause certain hidden dangers to product quality.
