Description
Technical field
The utility model relates to the tobacco field, is that a kind of pipe tobacco is carried test unit specifically, utilizes this device can realize that the short distance pipe tobacco is continuous, stablize, carry uniformly and feeding, and gathers relevant Key Experiment parameter.
Background technology
In cigarette serialization production run, the connection of inter process generally adopts belt conveying, vibrating transportation, cart transport and strength to carry this four kinds of mode of movements.Because belt is carried the material that should not carry big moisture and higher temperature, and it is serious to run material, the fed distance of vibrating transportation is short, transporting velocity is slower, the cart transport investment is big, control system complexity etc., therefore in actual production, the use occasion of these three kinds of mode of movements all has been subjected to certain restriction.Characteristics such as air-transport system has flexible arrangement, convenient management, is applicable to the level of various distances, vertical and curve conveying, and in course of conveying, can also reach technology purposes such as loose, removal of impurities, dehydration, cooling, dedusting.Pipe tobacco moves in closed pipeline simultaneously, and tobacco dust can not be dispersed into the workshop, avoids destroying workshop condition.Thereby air-transport system is widely used in the production of cigarettes, become the indispensable important device of domestic and international cigarette production line.But, air-transport system all is to realize long this single purpose of distance conveying at present, if and the design and use of total system are improper, just may cause the especially fibrous and foliated material fragmentation of some materials, thereby influence is transported to the tobacco quality that respectively rolls board.In actual production process this type of Study on Problems is had numerous inconvenience and not enough, for example pipe tobacco strength Conveying Theory is still immature, equipment is got material observational study etc. for opaque material inconvenience.In view of ubiquity and the importance of pipe tobacco strength conveying in the production of cigarettes process, can design a kind of special testing equipment, be specifically designed to short distance conveying and realization to continuous, stable, the uniform feeding of next stage processing apparatus, problem to be solved in the utility model just.
Summary of the invention
The purpose of this utility model is just at above-mentioned existing in prior technology problem and custom-designed a kind of pipe tobacco is carried test unit, this apparatus structure advantages of simple, and what emphasis solved is that pipe tobacco is in intrasystem flow characteristics control problem; This device can reach stable, even feeding and broken purpose is made in minimizing simultaneously.The amplification that this test unit can be next step hot experiment and following engineering lays the foundation.
The purpose of this utility model can be achieved through the following technical solutions: this pipe tobacco carries test unit to comprise box body, box chamber body is divided into feed chamber and returning charge chamber by the slotting dividing plate that extends straight down, and the bottom of described feed chamber and returning charge chamber is communication type structure (a U-shaped connected chamber), in the bottom of feed chamber and returning charge chamber and the following side of feed chamber, be provided with loosening air compartment by air distribution plate is corresponding respectively, fluidisation air compartment and side-blown air compartment, the bottom of these three air compartments is connected with three road blowpipes respectively, be provided with operation valve and speed measuring point in three road blowpipes, top in the feed chamber is provided with feed pipe, is connected with refeed line above the side of returning charge chamber.
In the utility model, three road blowpipes are connected with blower fan by the blast main, and described blower fan is regulated air quantity by frequency converter, and air quantity is at 0m
3/ h～2500m
3Adjustable continuously in the/h scope.The refeed line endpiece is connected with the material collector that matches with measuring apparatus.Described feed pipe is provided with the valve that is used to control mass flow, i.e. a horizontally disposed baffle plate.The plug-in mounting position of inserting dividing plate in the box chamber body is adjustable up and down.
This device corresponding component all adopts transparent organic glass to be made, and can conveniently observe, test.
The principle of work of test unit of the present utility model is: after the gas that is produced by fan blower enters trunk line, pipeline by three parallel connections, enter fluidisation air compartment, loosening air compartment, side-blown air compartment respectively, above each air compartment or under the effect of the air distribution plate of side, form uniform three strands of air-flows continuously; Simultaneously, the pipe tobacco that adds from hopper enters the feed chamber, under the acting in conjunction of fluidized wind, loosening wind, cross air blow, forms the Dual-Phrase Distribution of Gas olid of different operating modes in the U-shaped connected chamber.Wherein, it is to change the indoor material concentration of returning charge that fluidized wind mainly acts on, the concentration difference of formation and feed chamber, thus for entering the returning charge chamber smoothly, material provides power; Become flexible wind to the material inflation of bottom, feed chamber, it is expanded, the concentration difference of generation and the indoor material of returning charge also eats dishes without rice or wine to provide expulsive force for material by level simultaneously; Cross air blow obtains higher speed by the side direction spout, for pipe tobacco provides main drive by the aperture, and can effectively eliminate dead band bottom the feed chamber.
The operating process of this test unit is: at first fill up pipe tobacco by hopper in the charging standpipe, open blower fan then and transfer to default air quantity, mix up each testing tool.Just can begin the collection of relevant data when system stability and when reaching test request.The test pipe tobacco is acted on by air-flow and forms Dual-Phrase Distribution of Gas olid in the U-shaped connected chamber, enters the gatherer of cloth-bag type structure at last, does not just re-use after the test pipe tobacco enters gatherer, and the test gas medium is the air under the normal temperature.
This device is by repeatedly to the testing authentication of tobaccos such as leaf silk, stem, expansion thread, install working properlyly, any abnormal occurrence do not occur, proves absolutely the relevant research that utilizes the utility model device can carry out the pipe tobacco conveying.
The utility model test unit has following advantage:
1. this device adopts transparent organic glass to process, convenient observation, test.
2. this device adopts the independent experiment system, and the test pipe tobacco does not circulate, and can effectively reduce and make the influence that the broken tobacco structure of bringing changes.
3. agent set is small and exquisite, and the test inventory is little, the installation testing of convenient relevant instrument.
4. this device can be realized that the short distance pipe tobacco is stable, carry and feeding uniformly, various correlation parameters, Study of indexes when helping pipe tobacco and carrying.
