Summary of the invention
The purpose of this utility model just is being based on existing problem in the above-mentioned prior art and custom-designed a kind of pipe tobacco Dual-Phrase Distribution of Gas olid test unit, and this apparatus structure advantages of simple can be used for studying the flow characteristics of pipe tobacco under the air-flow effect under the cold conditions.Simultaneously, in conjunction with other dependence test technology, can be used for testing pipe tobacco conveying, fluidisation, motion, pipe tobacco and collide the relevant basic data of characteristics such as contact, reunion mutually.
The purpose of this utility model can be achieved through the following technical solutions: this pipe tobacco Dual-Phrase Distribution of Gas olid test unit comprises fluidized bed, wherein: the import and export at fluidized bed are communicated with circulation supply air system and pipe tobacco induction system respectively, and the circulation supply air system comprises blower fan, backwind tube, cyclone feeder return air elbow that is connected with fluidized bed and valve and the gas outlet that is arranged on the fan outlet end; The pipe tobacco induction system includes cyclone feeder, blanking gas lock feed pipe, blanking gas lock, sub-feed tube, drainage conduit, blanking gas lock discharge nozzle, feeder, the charging gas lock that is connected with fluidized bed successively; The transparent bed body of fluidized bed for ease of observing, be furnished with 3-8 instrument connection respectively at the differing heights place of fluidized bed, before bed body inlet, be reserved with a plurality of test probe mounting holes, the feeding quantity of feeder and systematic air flow respectively by frequency converter regulate (be described feeder and being used to circulate supply air system the wind-force source---blower fan inserts frequency converter in the mode that is electrically connected).
In the utility model, described fluidized bed body is to be processed by organic glass, and bed body xsect is a rectangle structure.The feeding quantity of described feeder makes it adjustable continuously at 0kg/h～300kg/h by the adjusting of frequency converter, and capable of circulation reinforced.Systematic air flow (being the air quantity of fluidized bed, cyclone separator) can make air quantity at 0m by the adjusting of frequency converter
3/ h～1700m
3/ h is adjustable continuously.
The basic functional principle of this test unit is, regulates fluidized bed inlet air quantity by frequency conversion fan, and feeding gas lock frequency converter is regulated trier amount material, and quantitative pipe tobacco is subjected to the air-flow of certain air quantity to act on the Dual-Phrase Distribution of Gas olid that forms different operating modes in the fluidized bed.
The main operating process of this test unit is, at first opens blower fan and transfers to default air quantity, mixes up each testing tool.Pack in feeder then certain pipe tobacco, feeding are simultaneously by changing the frequency adjustment feeding quantity of charging gas lock.Just can begin relevant test when system stability and when reaching test request.The test pipe tobacco is subjected to the bed that acts on fluidized bed of air-flow to form Dual-Phrase Distribution of Gas olid in the body, by fluidized bed body, through cyclone feeder pipe tobacco is separated with gas medium from top to bottom, and the test gas medium is an air.Gas medium by cyclone feeder return air elbow to backwind tube and reducing bend recycle.The test pipe tobacco then successively via blanking gas lock feed pipe, blanking gas lock to sub-feed tube, according to the test concrete condition, the test pipe tobacco is discharged from drainage conduit and is not re-used, or from blanking gas lock discharge nozzle to the feeder cyclically charging.
To the testing authentication of materials such as leaf silk, stem, equipment work is normal, any abnormal occurrence do not occur, proves absolutely the relevant research that utilizes the utility model can carry out the pipe tobacco Dual-Phrase Distribution of Gas olid by repeatedly.
Test unit of the present utility model has following advantage:
1. feeder and gas-solid fluidized bed bed body mainly process convenient observation, test with organic glass.
2. the feeding quantity of feeder and air quantity gas-solid fluidized bed, cyclone separator can be realized regulating continuously by frequency converter.
3. the feeder cyclically charging can reduce the test inventory.
4. install small and exquisitely, the test inventory is little, and each several part convenient disassembly, the also installation of convenient relevant testing tool simultaneously.
