The present invention discloses a kind of method using the standard testing built-in testing pneumatic separating device efficiency of separation, the testing piece is used as pneumatic separating measure of merit standard specimen, the testing piece is made using offal film-making poststaining, by standard specimen with material wind selection device during use, according to the standard specimen distribution results after sorting, the working status of wind sorting equipment is evaluated, by the evaluation to equipment state, indirect and accurate evaluation wind sorting equipment the efficiency of separation.
Description
Technical field
Present invention relates particularly to a kind of method using the standard testing built-in testing pneumatic separating device efficiency of separation.
Background technology
Wind sorting equipment is the common equipment of tobacco industry, includes the stalk leaf sorting separator of beating and double roasting, throwing
Stem, stalk label wind selecting separator, and cigarette machine stalk label selection by winnowing separation.
The pneumatic separating operation principle of wind sorting equipment, mainly using the air-flow of certain wind speed, by needing selection by winnowing
Material, utilize the density contrast exclusive or weight in material between tobacco leaf and offal, between stem and stalk label, between pipe tobacco and stalk label
Difference, during airflow blow, is separated according to material movement difference, achievees the purpose that pneumatic separating.
Different wind sorting equipments leads to because the difference on equipment poor designs xor operation, its separating effect are had nothing in common with each other
The common efficiency of separation is evaluated, the part isolated to needs, is sorted ratio in actual, is calculated its efficiency of separation.Divide at present
Select efficiency rating, mainly the material after selection by winnowing is sampled, then by manual sorting, calculate the ratio of its qualified component.
As described above, the current evaluation method of the efficiency of separation, which relies primarily on, manually carries out, it is necessary to take a certain number of samples
Product, by manual sorting, then calculate and judge, there are problems with：
1) cumbersome, the efficiency of separation judges to need sampling, manual sorting, detection, calculating, operates loaded down with trivial details, operation difficulty
Greatly.
2) standard disunity, different people judges difference to material, therefore, it is determined that standard disunity, with stem and obstructs label
Between judge exemplified by, to the thick stem of a bit, some judgements are signed for stalk, and some judgements are qualified stem, therefore, although in theory only
There is a standard, but actual perform varies with each individual, and causes standard disunity.
3) detection process takes, and according to requirement of the industry to detection method, has detailed rule to the sample size of sampling detection
Fixed, then manual sorting, whole sort process take general 60 minutes or so, occupy largely manually, also influence detection speed
Degree.
The content of the invention
The object of the present invention is to provide a kind of pneumatic separating using unified standard to test standard specimen, evaluates wind sorting equipment
Working status, and by the evaluation to equipment state, evaluates indirectly and accurately wind sorting equipment in the operating condition
The method using the standard testing built-in testing pneumatic separating device efficiency of separation of the efficiency of separation.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of making of standard test piece, comprises the following steps：
1) wind sorting equipment tested needs, with vertical pneumatic concentration, the material tested out respectively in selection by winnowing is averagely outstanding
Floating speed, the material under selection by winnowing are averaged floating velocity；
2) offal is used to make the stalk piece of different-thickness by silk cutting machine as making material, passing through high accuracy
Air classifier selects the stalk piece of different floating velocities and categorised collection.
3) floating velocity and the material in pneumatic separating device the selection by winnowing consistent stalk piece of floating velocity that is averaged are designated as a samples,
B samples are designated as equal or close to the be averaged stalk piece of floating velocity of the material under selection by winnowing；For ease of distinguishing, a samples are contaminated using food coloring
For blueness, b samples food coloring dye is red.
4) each 50 proportionings of a samples and b samples are packed, becomes the testing piece of the air classifier efficiency of separation.
Another technical problem to be solved by this invention is a kind of using standard testing built-in testing pneumatic separating device point to provide
The method for selecting efficiency, comprises the following steps：
1) in use, under the normal production status of wind sorting equipment, pneumatic separating is entered making standard specimen mix in material
Equipment；
2) standard specimen after selection by winnowing is collected, the efficiency that formula calculates its sorting is calculated as follows：
The efficiency of separation=ξ × (the b samples quantity under a samples quantity+selection by winnowing in selection by winnowing)/input standard specimen total amount
Wherein, ξ is correction factor, and computational methods are：
The selection by winnowing efficiency for the selection by winnowing efficiency that ξ=national standard detection method obtains/tested by standard specimen.
Principle explanation：
Root is it was found that any one wind sorting equipment, in the case of screening installation working status is constant, to equal state
Material, its efficiency of separation is stable, and in the case of screening installation working status changes, using identical material into
Row sorting, its efficiency of separation can also be affected, and screening installation working status is very aobvious with the actual efficiency of separation presence of air classifier
The linear corresponding relation of work, therefore, we can use the pneumatic separating test standard specimen of standard, test evaluation wind sorting equipment
Working status, by the evaluation to equipment state, indirect and accurate evaluation wind sorting equipment the efficiency of separation.
This programme is making and tests standard specimen, test evaluation wind sorting equipment work shape using the pneumatic separating of standard
State, by the evaluation to equipment state, indirect and accurate evaluation wind sorting equipment the efficiency of separation.Made by this method
With instead of current wind sorting equipment efficiency of separation sampling method of determination and evaluation.
The technology of the present invention effect major embodiment is in the following areas：Evaluation judges that result is more representative, since standard specimen has
Uniformity, is adapted to the similar pneumatic separating device test of different location, and test result is stronger with reference to property, comparativity；Operating procedure letter
Clean, operating method is simple, it is only necessary to standard specimen is mixed into production material, then tracks standard specimen distribution situation, you can calculates outlet air
The efficiency of separation of power screening installation；Standard is unified, and the efficiency of separation tested out using standard specimen, has universal representativeness；Behaviour
Make quickly, whole test process can be completed for 5 minutes or so.
