Abstract
The utility model discloses a kind of waste collection box of vacuum extractor, especially device when utilizing vacuum extractor to extract furfural, waste liquid collected is related to, comprise the outer handle of housing, inward recess, groove and disposable box, housing is placed in the bottom of vacuum extractor; The corresponding vacuum extractor in the inward recess position of housing bottom side vacuumize interior hole site; Have air can the groove of free flow above inward recess, housing both sides be provided with outer handle.Groove in this device can make the endoporus locational space that vacuumizes of vacuum extractor upper space and extractor circulate unimpeded; In the process of collecting waste liquid, do not need to change test tube, simple to operate, can raise the efficiency, the quality of SPE can be ensured simultaneously.
Description
Technical field
The utility model relates to device during furfural extraction in a kind of transformer oil, especially relates to the device collected waste liquid when utilizing vacuum extractor to extract furfural.
Background technology
In transformer oil, furfural is a kind of main compound that in transformer, the degraded of solid insulation paper generates.Generally have employed the higher high performance liquid chromatography of operability at present both at home and abroad and detect furfural content in oil, by furfural content in test oil, to assess the paper insulated degree of aging of transformer, but utilize high performance liquid chromatography to detect in oil before furfural content, first furfural will be extracted from transformer oil sample.Solid phase extraction is a kind of extracting process that efficiently can extract furfural in transformer oil rapidly of rising in recent years.
When utilizing solid phase extraction to extract furfural in transformer oil, oil samples used and reagent are by after solid-phase extraction column, and waste liquid is flowed out by the end opening of solid-phase extraction column.Usually, the end opening of solid-phase extraction column is connected to the tubule of a water conservancy diversion, is furnished with test tube fixed mount in vacuum extractor, after the test tube fixed mount being provided with test tube is put into vacuum extractor, water conservancy diversion tubule can insert in test tube, can be collected from the waste liquid after solid-phase extraction column by test tube.
By the height of vacuum extractor and the restriction of inner space, for collecting the maximum 20mL of test tube capacity of waste liquid.A test tube cannot be realized install, collect the waste liquid holding single extraction process and produce.Need to change test tube, so operate not only complicated operation, lose time, need operating personnel's energy high concentration, and in the process not completing extraction, mobile solid-phase extraction column, easily affects SPE quality.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of waste collection box of vacuum extractor, once can collect the waste liquid holding single extraction process and produce.
For achieving the above object, the utility model adopts following technical proposals:
A kind of waste collection box of vacuum extractor, comprise the outer handle of housing, inward recess, groove and disposable box, housing is placed in the bottom of vacuum extractor, the corresponding vacuum extractor of the inward recess of housing bottom side vacuumize interior hole site, have the groove of free air circulation above inward recess, housing both sides are provided with outer handle.
Described housing should be transparent material.
Described housing and vacuum extractor wall tight.
What described inward recess avoided vacuum extractor vacuumizes endoporus.
The beneficial effects of the utility model are,
Groove in this device can make the endoporus locational space that vacuumizes of vacuum extractor upper space and extractor circulate unimpeded; In the process of collecting waste liquid, do not need to change test tube, simple to operate, can raise the efficiency, the quality of SPE can be ensured simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein 1. housings, 2. outer handle, 3. inward recess, 4. groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A waste collection box for vacuum extractor, as shown in Figure 1, comprise housing 1, outer handle 2, inward recess 3, groove 4, described groove 4 extends to housing 1 top, and housing 1 is placed in the bottom of vacuum extractor; Bottom housing 1, the corresponding vacuum extractor in inward recess 3 position of side vacuumizes interior hole site; Have air can the groove 4 of free flow above inward recess 3, housing 1 both sides be provided with outer handle 2.
Described housing 1 should be the transparent material of acid/alkali-corrosion-resistant, can observe the amount of liquid in housing 1;
Described housing 1 and vacuum extractor wall tight, but housing 1 can propose vacuum extractor by the outer handle 2 of lift;
Described inward recess 3 can make the endoporus that vacuumizes of vacuum extractor carry out normal work;
Described groove 4 should not touch the mozzle that vacuum extractor top is installed;
Described groove 4 can make the endoporus locational space that vacuumizes of vacuum extractor upper space and extractor circulate unimpeded;
Described outer handle 2 highly should not touch the bottom of the upper cover of vacuum extractor;
Described outer handle 2 should with the housing at place at same plane;
Described outer handle 2 should bear weight time housing full liquid (in water).
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
