Method and device for separating tobacco gas materials

Abstract

The invention discloses a method for separating tobacco gas material, which comprises that first using horizontal deposit tube to dynamically horizontally deposit the material in forward process, to move most material along the bottom of the deposit tube and uses airflow to feed the deposited material into the separating box, and the material via self weight in the separating box is separated from airflow to be discharged via the outlet under the separating box, and the airflow is discharged after passing through the baffle plate above the separating box. The invention has high separating accuracy and resource utilization or the like.

Description

technical field [0001] The invention relates to a technical method of tobacco processing, in particular to a method for realizing the separation of air and material during the pneumatic conveying process of tobacco. Background technique [0002] In the tobacco production process, a large number of pneumatic conveying methods are used to transport or lift tobacco materials over a long distance. At a predetermined location, the air material separation device is used to separate the tobacco materials from the air flow. In many cases, pneumatic conveying has obvious advantages. Simple, with a small footprint, it is irreplaceable. In the existing pneumatic conveying system, commonly used air-material separation devices include cyclone blanking devices and tangential blanking devices, etc. These blanking devices generally use centrifugal force to achieve air-material separation. The material obtains a relatively high speed, and the tobacco material often needs to change direction...

AI Technical Summary

Problems solved by technology

In the existing pneumatic conveying system, commonly used air-material separation devices include cyclone blanking devices and tangential blanking devices, etc. These blanking devices generally use centrifugal force to achieve air-material separation. The material obtains a relatively large speed, and the tobacco material often needs to change direction sharply during the separation process. The tobacco material bears a large impact force, and there is inevitably a large amount of crushing, resulting in waste.

Moreover, the separation accuracy of the existing air-material separation device is low, and a large amount of usable tobacco materials are not separated, and are brought into the dust removal system with the air flow, causing waste again.

Another major defect in the existing gas-material separation method is that the pressure loss of the gas-material separation device is large, which means that the system consumes a lot of energy, and the existing gas-material separation device often has the problem that the higher the separation accuracy, the greater the pressure loss. great feature

[0003] Pneumatic conveying in other fields besides the tobacco industry also has the defects of high energy consumption and large losses. Moreover, due to the long-term scouring of materials, the gas-material separation device is prone to failure and has a short service life.
