Description
Technical field
The present invention relates to Nitrogen evaporator technical field, refer in particular to a kind of drawer that automatically nitrogen blow needle can be inserted concentration test tube
Device.
Background technology
Nitrogen evaporator（Termovap Sample Concentrator）It is widely used in farming residual analysis, commodity inspection, food, ring
Industries such as border, pharmacy, biological products and in the sample preparation in liquid phase, gas phase and mass spectral analysis.Nitrogen evaporator generally by plus
Thermal, sample positioning device and feeder three part composition.Nitrogen or through feeder adjustment flow after, blown by nitrogen
Needle blow enters to be fixed in the shuttle being placed in heater on sample positioning device, makes having in sample in shuttle
Machine solvent volatilizees rapidly, thus realizing the concentration to sample.
In prior art, nitrogen blow needle is usually fixed, needs to shift onto below nitrogen blow needle concentrating test tube, nitrogen blows when nitrogen blows
The syringe needle of pin has a segment distance from the mouth of pipe, and the distance in the syringe needle chaotropic face of nitrogen blow needle is farther, has a disadvantage in that：Due to syringe needle away from
So that nitrogen blows, effect is poor farther out in chaotropic face, and when nitrogen blows, inboard wall of test tube easily produces condensation.
In view of this, for overcoming the described defect of prior art, the present invention develops one kind and automatically can insert nitrogen blow needle
Concentrate the drawer of test tube, this case thus produces.
Content of the invention
It is an object of the invention to provide a kind of can insert, by nitrogen blow needle, the drawer concentrating test tube automatically, to reduce nitrogen
The consumption of gas, improves nitrogen and blows efficiency, shortens concentration time, and reduces the condensation of test tube wall.
For reaching above-mentioned purpose, the solution of the present invention is：
A kind of automatically nitrogen blow needle can be inserted the drawer concentrating test tube, include there is the bearing of crane and there is locating rack
Drawer, drawer sliding horizontal on bearing, concentrate test tube be placed on installing rack, crane moves up and down on bearing, and nitrogen blows
Pin is arranged on crane, drawer related concentration test tube with respect to bearing near nitrogen blow needle slide when, synchronously order about crane phase
Bearing is moved down, and the insertion of nitrogen blow needle concentrates in test tube.
Further, bearing arranges guide holder, crane arranges the axis of guide, on guideway is connected in guide holder
Lower movement, axis of guide upper end connects crane, and roller is installed in axis of guide lower end；Track is correspondingly arranged on drawer, the axis of guide
Roller sliding horizontal in orbit, when pull drawer orders about the roller of the axis of guide and slides to drawer surface by track, the axis of guide moves down
Related crane moves down, and the insertion of nitrogen blow needle concentrates in test tube.
Further, track is more than the syringe needle of nitrogen blow needle and concentration test tube when roller is located on track with respect to the height of drawer
The distance between the mouth of pipe.
Further, the two ends of track are respectively provided with slope, and roller slides to track, roller through wherein one slope by drawer surface
Through another slope, drawer surface is slided to by track.
After such scheme, the related concentration test tube of drawer of the present invention near nitrogen blow needle relative seat slide when, synchronous drive
So that crane relative seat is moved down, and the insertion of nitrogen blow needle concentrates in test tube.Therefore, the present invention pushes concentrating test tube under nitrogen blow needle
Fang Shi, nitrogen blow needle is automatically inserted in concentration test tube, and its structure is simple, without driven by power, improves nitrogen and blows efficiency and reduce nitrogen
Consumption, improves thickening efficiency.Meanwhile, the syringe needle chaotropic face of nitrogen blow needle is nearer, is effectively reduced condensation.

Nitrogen blow needle 4.
Specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Refer to described in Fig. 1 to Fig. 3, a kind of drawer dress that automatically nitrogen blow needle can be inserted concentration test tube that the present invention discloses
Put, including the bearing 1 with crane 11 and the drawer 2 with locating rack 21.
Drawer 2 sliding horizontal on bearing 1, that is, pull drawer 2 it is slided with respect to level on bearing 1.Concentrate examination
Pipe 3 is placed on installing rack 21, as shown in figure 1, concentrating test tube 3, to be set to a row multiple.Crane 11 on bearing 1 on move down
Dynamic, nitrogen blow needle 4 is arranged on crane 11, as shown in figure 1, nitrogen blow needle 4 be correspondingly arranged multiple for a row.
The related concentration test tube 3 of drawer 2 with respect to bearing 1 near nitrogen blow needle 4 slide when, synchronously order about crane 11 relatively
Seat 1 moves down, and nitrogen blow needle 4 insertion concentrates in test tube 3.Nitrogen blow needle 4 is automatically inserted in concentration test tube 3, improves nitrogen and blows efficiency and subtract
Few nitrogen use level, improves thickening efficiency.Meanwhile, the syringe needle chaotropic face of nitrogen blow needle 4 is nearer, is effectively reduced condensation.
In the present embodiment, bearing 1 arranges guide holder 12, the axis of guide 13,13 sets of the axis of guide are arranged on crane 11
It is connected in guide holder 12 and moves up and down, the axis of guide 13 upper end connects crane 11, roller 14 is installed in the axis of guide 13 lower end.In drawer
It is correspondingly arranged track 22 on 2, sliding horizontal in roller 14 in rail 22 below the axis of guide 13, pull drawer 2 orders about the axis of guide
When roller 14 below 13 slides to drawer 2 surface by track 22, the axis of guide 13 moves down related crane 11 and moves down, and nitrogen blow needle 4
Insertion concentrates in test tube 3.
Be preferably, track 22 with respect to drawer 2 height be more than roller 14 be located at track 22 on when nitrogen blow needle 4 syringe needle with
