Description
Technical field
Present invention relates generally to the gathering and processing apparatus field of material sample, and in particular to one kind is used for sample pneumatic conveying
The power cabinet of system.
Background technology
For material（Such as ore, coal）The sampling of sample, sample preparation, chemical examination work, every country have pressure standard, must
The chemical industry of gathering and processing that sample must be carried out in accordance with standard is made.The sampling of sample, sample preparation, the criterion of the chemical examination course of work are not destroy sample
Under the premise of product are representational, the sample granularity for collecting is gradually reduced, quality is also gradually reduced, until meeting laboratory assay
To the granularity and quality of sample（Weight）Required precision, then carries out the assay of correlation to satisfactory sample.
Such as gathered and processed with the sample of coal and turn to example, actually a kind of process of sampling analysis, coal samling and sample preparation
Purpose, is that can represent the experiment coal sample for being sampled coal by the gross to obtain its experimental result.Coal is a kind of uneven
Material（Granularity, mass property distribution etc.）, the quality of coal is sampled typically all than larger（Tens tons are arrived tens of thousands of tons）, from quilt
The process of representative part of coal is taken " sampling " in sampling coal, there is mechanical sampling, artificial sample, half machinery at present
The various ways methods such as sampling.After adopting sample by standard, next process is " sample preparation ", sample making course typically have broken, mixing,
The processes such as division, drying.Sample carries out the sample " chemical examination " of next step after making, sample is analyzed.Whether " adopt
Sample ", " sample preparation " or " chemical examination ", can not there is the loss of sample during this, it is impossible to enough make sample occur some physics or
Chemical change, will otherwise impact to final result of the test.
In material（Such as ore, coal）, it is necessary to the sample that will be gathered and processed is from originally in sampling, sample preparation, the chemical examination work of sample
The station of link（Laboratory）Transhipment is delivered to the station of next link（Laboratory）To carry out next stage work.In turning for sample
Transport is given during this, and the precision control of quality of sample, transhipment transporting velocity are particularly important.The transhipment conveying work of existing sample
In work, partly by the way of Pneumatic pipe conveying, Pneumatic pipe induction system includes power cabinet, from power cabinet to pneumatic conveying
Blowing in pipeline, the sample bottle blown in malleation mode in pipeline is transmitted, or from power cabinet to being taken out in air conveying line
Wind, the sample bottle inhaled with negative pressure mode in dynamic pipeline is transmitted.There is following technical problem：
（1）Existing power cabinet uses two blower fans to blow, exhausting operation, the setting of two blower fans cause equipment overall compared with
Greatly, it is necessary to larger space is laid, cause the use requirement to place high.
（2）Two fans set and cause that the pipeline connection inside high cost, cabinet is complicated, inconvenient maintenance maintenance operation.
（3）Two fans are set causes fan vibration big, and the air-tightness for pneumatic transmission pipeline produces destruction, simultaneously because
Two fans noise is big, causes not environmentally.
（4）Part uses two power cabinets, a power cabinet to be only equipped with hair-dryer, another outfit air exhauster, two
Individual power cabinet connects Pneumatic pipe simultaneously.This is to cause high cost, and equipment is big.Two is whether two designs or of cabinet
The design of individual cabinet two fans, in production operation, two blower fans are likely to occur conflict, i.e., the blowing when another but also same
When exhausting, this has a strong impact on the security of pneumatic transfer, is likely to result in pipeline and sample bottle breakage, has a strong impact on sample physical
And precision.Two states of blower fan can not especially be adjusted flexibly according to the real-time pressure situation in air flue transmission pipeline, make
Obtain risk big.Energy loss is big.
The content of the invention
Technical problem solved by the invention is：For the problem that prior art is present, there is provided a kind of simple structure is tight
Gather, low cost, Environmental Safety, be easily installed the good power cabinet for sample pneumatic conveyer system of maintenance, pneumatic conveying effect.
