A vacuum device and activated carbon packaging machine in the process of packaging powdered activated carbon

Abstract

The invention discloses a vacuumizing method in the powdered activated carbon packaging process. The vacuumizing method comprises the steps that in the packaging process of an activated carbon packaging machine, when powdered activated carbon enters a material bin through a feeding mechanism, the powdered activated carbon in the material bin is weighed through a weighing device, then the weighed powdered activated carbon enters an activated carbon packaging bag, and then the powdered activated carbon in the activated carbon packaging bag is vacuumized through a vacuumizing device. The vacuumizing device comprises a vacuum pump, a vacuum tank, a vacuumizing control valve, a micro-porous pipe with micropores formed in the pipe wall and a lifting mechanism used for ascending and descending of the micro-porous pipe. An air inlet of the vacuum tank communicates with one end of an air conveying pipe through the vacuumizing control valve, and the other end of the air conveying pipe communicates with the micro-porous pipe. The vacuumizing method which is adjustable in air removal amount, high in bagging efficiency and good in finished product quality and is used for separating the activated carbon and air in the powdered activated carbon packaging process, the vacuumizing device and the activated carbon packaging machine are provided.

Description

technical field [0001] The invention relates to the packaging field of powder (solid) materials, in particular to a vacuuming method, a vacuuming device and an activated carbon packaging machine in the packaging process of powdery activated carbon. Background technique [0002] Packaging equipment is often used in people's lives and brings convenience to people's lives. For some powdered activated carbon, due to the low density, small particle size, and large gas content, in the existing conventional packaging, it is difficult to complete the rated packaging weight in standard bags within the normal packaging time, and the original packaging method of multi-step precipitation is usually used , This method usually takes a long time to pack, has low efficiency, and the labor intensity of the workers is high, and the dust spreads greatly, which seriously affects the working environment of the factory area and the health of the workers. In order to solve the packaging quality, ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme has improved some problems of the prior art to a certain extent, but this method has at least the following defects: this method is fixed for the extruded amount of unit air, and the unit vacuum degassing amount cannot be designed too large, or it is easy to As a result, the activated carbon sticks into blocks, which affects the packaging speed. At the same time, the degassing amount per unit time cannot be adjusted. For some activated carbons with a large gas content, it still cannot meet the packaging efficiency and volume requirements.
