A conveying experimental device for measuring the pneumatic conveying performance of expanded graphite bulk materials

Abstract

The invention relates to a conveying experimental device for pneumatic conveying performance measurement of an expanded graphite loose material. The conveying experimental device comprises a hopper, a gas-solid separator, a negative pressure fan and a conveying pipeline and an adjusting detection device. The conveying pipeline is connected to the hopper and the gas-solid separator, a mixing proportional valve and a first negative pressure gauge are arranged in a position where the hopper is connected, a second negative pressure gauge is arranged on the right side, connected to the inlet of the gas-solid separator, of the conveying pipeline, and the right air outlet of the gas-solid separator is connected to the negative pressure fan through the adjusting detection device; in the gas-solid separator, a rotating screen with a minigroove metal net and a fixed sleeve in clearance fit form a gas-solid separating structure; the gas-solid separator comprises a sealed box body, the fixed sleeve, the minigroove metal net, the rotating screen, a star discharger, a rotating shaft and a bearing pedestal. The conveying experimental device provided by the invention solves the problems that the expanded graphite is liable to block the pipeline and the material is broken by means of an existing vacuum sucking and feeding mode, and meanwhile, the conveying experimental device can collect pneumatic conveying performance parameters of the expanded graphite particles in real time, thereby providing test equipment and method for researching pneumatic conveying basic data of ultralight loose materials.

Description

technical field [0001] The invention relates to a negative pressure pneumatic conveying device, in particular to a conveying experimental device for measuring the pneumatic conveying performance of expanded graphite bulk material. Background technique [0002] Expanded graphite particle material is a highly efficient adsorption material suitable for emergency cleaning of offshore oil spills. It has excellent adsorption performance for crude oil. It is currently found to be the material for offshore oil spill cleaning with the highest oil absorption ratio and oil absorption efficiency. Based on the characteristics of expanded graphite, such as small density, large volume, large space occupation, loose and porous structure, and easy to fly and scatter with the movement of airflow, its transportation method mostly adopts pipeline pneumatic transportation to realize the centralized delivery of materials from several points to one. place, or distributed from one place to several ...
