Description

Technical Field

[0001] The utility model relates to the field of activated carbon particle transportation, in particular to a sealed transportation device for activated carbon particles. Background Art

[0002] Activated carbon is a highly porous adsorption material with a large specific surface area and adsorption capacity. After the activated carbon is saturated with adsorption, it can be desorbed and regenerated for recycling; therefore, the activated carbon adsorption and desorption system is a technology widely used in environmental governance, industrial production, chemical laboratories and other fields.

[0003] Activated carbon particles are generally stored in a silo and can be transported by a screw conveyor when needed. Currently, the discharge port of the silo and the feed port of the screw conveyor are usually directly connected by a flange, or connected by a flange after adding an expansion joint. For example, a closed-type activated carbon storage and transportation system disclosed in Chinese Patent CN211643906U is like this. An insertion valve, an electric rotary valve and an expansion joint are arranged between the activated carbon storage bin and the screw conveyor. It is relatively common to use this flange connection method with one discharge port corresponding to one feed port. The company applied for Patent CN217534656U, a uniform and controllable blanking system for granular materials, in 2022. This patent discloses that a perforated plate is arranged at the bottom of the stacking chamber, and a perforated blanking valve plate is arranged below the perforated plate, that is, this application can achieve multi-point blanking, which requires the screw conveyor to be able to feed at multiple points. If the flange connection method is still used between the two, a large number of bolts need to be installed, which is time-consuming, and it is not convenient for subsequent maintenance of opening the cover of the screw conveyor.
