Tracer chain detection method and device for tracking flow track and speed of bulk material

Abstract

The invention relates to a tracer chain detection device for tracking the flowing track and speed of a bulk material. The device is characterized by comprising a vertical bulk material device for loading a bulk material, a tracer chain transmission system for tracking the flowing of the bulk material, and a tracer chain detection system, wherein the vertical bulk material device comprises a stock bin, a distributing mechanism and a discharging hopper, the distributing mechanism is arranged at the top of the stock bin, the discharging hopper is arranged at the lower end of the stock bin, the bulk material is distributed by the distributing mechanism to enter the stock bin and then discharged by the discharging hopper from the bottom of the stock bin, in the tracer chain transmission system, a front-end tracer and a tail-end marker are connected through a pulley block and a lifting rope, the front-end tracer is arranged in a stock bin, the tail-end marker is arranged outside the stock bin, the motion direction of a tail end marker in the tracer chain transmission system is changed through a pulley block, and the motion change of the tail end marker forms real-time flow parameters, and the real-time flow parameters are transmitted to a flow field calculation unit through an information transmission unit for measurement and calculation of a flow track, speed distribution, residence time and a moving distance.

Description

technical field [0001] The invention relates to a tracer chain detection method and device for tracking the flow trajectory and speed of bulk materials. Background technique [0002] Different from solid, gas and liquid, bulk is a special form of existence of matter, which mainly involves mineral mining and processing, metallurgy, coal, coking, petrochemical, medicine, food, agriculture and other fields. The research objects are sinter, ball Lump ore, steel scrap, slag, coke, ore, limestone, dolomite, medicine, food, grain, etc. The flow characteristics of bulk materials and their detection methods have always been difficult problems to be solved in the field of bulk science and engineering. The flow of bulk material in the closed chamber under the action of gravity is prone to a series of bad material flow conditions such as funnel flow and segregation flow, resulting in poor discharge of bulk material, blockage, drop in bulk material flow rate, and bulk material flow in t...

Problems solved by technology

This method is suitable for the basic experiment of measuring the velocity distribution of particles in a fluidized bed in the laboratory or for the study of the velocity distribution of a limited number of visible tracer particles in an open space. It is not suitable for the pilot test of the flow characteristics of the bulk material bed in a non-transparent device. or industrial test
