As shown in fig. 1-2, the nitrogen blowing instrument comprises a base 20 and a test tube mounting seat 10, wherein a water bath is arranged in the base 20, test tubes 90 can be mounted on the test tube mounting seat 10 in a detachable mode in a matrix distribution mode, the test tube mounting seat 10 is mounted on the base 20 in a detachable mode, a ventilation pipeline network 11 is arranged inside the test tube mounting seat 10, the ventilation pipeline network 11 is provided with an air inlet 14, the air inlet 14 is used for being communicated with an air source 40, the ventilation pipeline network 11 is communicated with a plurality of air blowing pipes 12, each air blowing pipe 12 is used for cleaning one test tube 90, and each air blowing pipe 12 is connected with a control valve. Each test tube mount 10 may be provided with 8×10=80 positions for mounting test tubes 90. The test tube 90 may be mounted by clamping the test tube 90 by a clamping device in the drawings of the present embodiment, or may be mounted on the test tube mounting base 10 in other manners.
This nitrogen blows appearance is through being connected test tube mount pad 10 with detachable mode and base 20 to test tube mount pad 10 can detachable installation test tube 90, can utilize a test tube mount pad 10 to install test tube 90 when blowing the appearance on nitrogen and wash the drying, utilize other test tube mount pad 10 to install test tube 90 again, treat that test tube 90 in the last test tube mount pad 10 all washs the drying after, can directly install new test tube mount pad 10 on base 20, directly washs to a large amount of auxiliary man-hours of equipment have been practiced thrift.
Moreover, by providing a control valve for each of the air-blowing pipes 12, the control valve can be closed immediately after the test tube 90 cleaned by the air-blowing pipe 12 is found to be dried, thereby reducing the air consumption of the test tube 90 that has been dried and concentrating the residual air in the residual test tube 90 that needs to be blown for cleaning. The use efficiency of the cleaning gas is improved. While also reducing the overall cleaning operation time of the test tube 90.
Specifically, the test tube mount 10 is plate-shaped, and the air inlet 14 is provided on the top surface of the test tube mount 10.
Specifically, the base 20 has a slide bar 21, and the cuvette holder 10 is capable of sliding on the slide bar 21. More specifically, the test tube mounting base 10 is provided with a positioning clamp 32, the positioning clamp 32 is provided with two positioning parts, one positioning part is provided with a threaded hole, the other positioning part is provided with a through hole, and the positioning bolt 31 passes through the through hole and is in threaded connection with the threaded hole.
Through setting up base 20 and test tube mount pad 10 into sliding connection, can be to the test tube 90 of difference, the height of different test tube mount pad 10 is selected and fixed to the cleaning needs of different types of test tubes 90 have been adapted. By providing the positioning bolts 31, after the test tube mount 10 is moved to a desired position, the test tube mount 10 can be fixed to the slide rod 21 by screwing the bolts.
The action principle of the embodiment is as follows:
before use, a plurality of test tubes 90 are mounted on the test tube mount 10, then the test tube mount 10 is inserted from the top of the slide bar 21, and the positioning bolts 31 of the positioning clamps 32 of the test tube mount 10 are tightened so that the positioning clamps 32 clamp the slide bar 21. And the air inlet 14 of the test tube mounting seat 10 is connected with the air tube, and specifically, the air inlet can be a quick plug connector so as to improve the connection speed.
The gas source 40 is started, nitrogen in the gas source 40 enters the ventilation pipeline network 11 through the gas inlet 14, specifically, the ventilation pipeline network 11 comprises 10 transverse pipes and 8 longitudinal pipes in the embodiment, the 10 transverse pipes and the 8 longitudinal pipes intersect to form 80 intersection points, and a vertical pipe is arranged at each intersection point to be communicated with the gas blowing pipe 12. Then enters the air blowing pipe 12 through the air pipe network 11, and blows the mounted test tube 90 through the air blowing pipe 12. Since the outside of the test tube 90 is immersed in the heated hot water, the test tube 90 is also heated, and the moisture in the test tube 90 absorbs heat to evaporate into water vapor, and is carried out by the nitrogen gas blown into the test tube 90 by the gas blowing pipe 12.
When the tube 90 is found to have been dried. The control valve of the blowing pipe 12 of the test tube 90 which has been dried is closed, so that the gas is concentrated in the blowing pipe 12 of the test tube 90 which has not been dried, thereby shortening the overall time of drying the test tube 90 and improving the working efficiency.
Example two
As shown in fig. 3 and 4, this embodiment is different from embodiment 1 in that an air inlet 14 is provided at the side of the test tube mount 10, a control valve is a manual control valve 13, and the position of the control valve on each of the air blowing pipes 12 gradually decreases as the distance between the air blowing pipe 12 and the air inlet 14 increases.
Through setting the height of manual valve to be positive and negative with the air inlet 14 distance of blowing pipe 12, can utilize the characteristics that the high amount of wind of blowing pipe 12 atmospheric pressure that is nearer to the import is big, blow-dry partial test tube 90 earlier to can close this partial blowing pipe 12 earlier, thereby concentrate the amount of wind of remaining blowing pipe 12 to the blowing pipe 12 that has not blow-dried corresponding test tube 90 yet, in order to improve the operating efficiency who weathers all test tubes 90 on the test tube mount pad 10.
Specifically, at the outside of each of the air blowing pipes 12, the test tube mount 10 is provided with a test tube 90 holding device, the test tube 90 holding device includes a plurality of holding pieces, the holding pieces are elastic holding pieces 15, the elastic holding pieces 15 can generate an acting force that makes the elastic holding pieces 15 move toward the air blowing pipe 12 when being deformed, a plurality of elastic holding pieces 15 for holding each test tube 90 are detachably connected with a test piece 16, and one side of the test piece 16 facing the test tube 90 is coated with a test reagent. The test strip 16 may have a slot extending from the center of the circle in a direction to form a notch that allows the test strip 16 to be placed over the outside of the lance 12. The width of the slot may be the same as the outer diameter of the lance 12 so that the notch of the test strip 16 can be snapped onto the outside of the lance 12. At the same time, the test strip 16 also has a protruding ear that can be used to hold the test strip 16 by the operator's hand to place it into the mouth of the test tube 90.
By providing the test piece 16, the test piece 16 can be placed in the elastic holding pieces 15 when the test tube 90 is to be dried or is considered to be possibly dried, thereby judging whether the test tube 90 held by the set of elastic holding pieces 15 is dried. The test piece 16 may be used to detect whether the test tubes 90 close to the air inlet 14 are blown dry, and if so, the control valve for the air blowing pipe 12 for blowing these test tubes 90 may be closed to pull the test tubes 90 that have been blown dry out of the elastic holding piece 15.
The operation principle of this embodiment differs from that of embodiment 1 in that:
because the distance between each of the air-blowing pipes 12 and the air inlet 14 is different, the air-blowing pipes 12 closer to the air inlet 14 blow the water in the corresponding test tube 90 to be dried first because the air flow has small flow loss, small air pressure drop and high air pressure when reaching the closer air-blowing pipes 12 when flowing through the ventilation management network, so that the air flow through each air-blowing pipe 12 has large air flow.
When it is required to determine whether to blow dry exactly, the test piece 16 can be placed at the nozzle of the test tube 90, and since the anhydrous copper sulfate is attached to the lower surface of the test piece 16, when the water vapor in the test tube 90 encounters the test piece 16, the lower surface of the test piece 16 turns blue or green, so that it can be determined that the water in the test tube 90 is not completely blown dry.
Because the heights of the manual control valves 13 in this embodiment are different, after the test tubes 90 that are closer to each other are blown dry, the manual control valves 13 of the air blowing pipes 12 of the test tubes 90 are closed, and the test tube mounting base 10 is moved upward, so that the test tubes 90 that are blown dry first can be detached from the test tube 90 clamping device. Then, the test tube mounting seat 10 is moved back to the original height at which the test tubes 90 are immersed, and after those test tubes 90 which are closer to the test tubes 90 in the test tubes 90 at this time have been dried, the manual control valve 13 of the air blowing pipe 12 of the test tubes 90 can be closed. Since a portion of the test tube 90 has been removed before, it is convenient to close the manual control valve 13 a second time. This is repeated until all of the test tubes 90 are blow-dried. The new tube mount 10 is replaced.
Example III
As shown in fig. 5, this embodiment is different from embodiment 1 in that the air inlet 14 is provided at the top of the test tube mount 10, the control valve is mounted at the top of the test tube mount 10, the control valve has a valve core that can penetrate into the air blowing pipe 12, and the air blowing pipe 12 has different ventilation areas when the valve core is in different positions.
By installing both the air inlet 14 and the control valve on the top of the test tube mounting base 10, the air blowing pipe 12 of the test tube 90 which is dried first can be closed by an operator above to save ventilation, and the rest air is applied to the rest test tube 90 which is not dried yet, so that the air consumption is saved.
Specifically, at the outside of each of the air blowing pipes 12, the test tube mount 10 is provided with a test tube 90 holding device, the test tube 90 holding device includes a plurality of holding pieces, the holding pieces are elastic holding pieces 15, the elastic holding pieces 15 can generate an acting force that makes the elastic holding pieces 15 move toward the air blowing pipe 12 when being deformed, a plurality of elastic holding pieces 15 for holding each test tube 90 are detachably connected with a test piece 16, and one side of the test piece 16 facing the test tube 90 is coated with a test reagent. The shape and configuration of the test piece 16 are the same as those of the test piece 16 in the second embodiment.
By providing the test piece 16, the test piece 16 can be placed in the elastic holding pieces 15 when the test tube 90 is to be dried or is considered to be possibly dried, thereby judging whether the test tube 90 held by the set of elastic holding pieces 15 is dried. If the test pieces 16 are placed on the test tubes 90 held by the elastic holding pieces 15 at the edges, it can be verified whether the test tubes 90 are dried, and since the air blowing pipe 12 for cleaning the test tubes 90 is farthest from the air inlet 14, the air pressure is greatly reduced, so that the air flow rate is low, and theoretically the drying speed is the slowest and the time is the longest. When the test tubes 90 furthest from the air inlet 14 are blown dry, it can be determined that all of the test tubes 90 are also blown dry.
The difference between the operation principle of this embodiment and embodiment 2 is that:
when some test tubes 90 are dried, the manual control valve 13 at the top of the test tube mounting seat 10 can be closed to close the corresponding air blowing pipes 12 of the test tubes 90, so that the air flow is saved.

(1) In the embodiment 2 and the embodiment 3, the description is made of the case where the test piece is placed based on the specific arrangement of the air inlet and the air blowing pipe, and in practice, the test piece may not be based on the two cases, that is, as long as the test tube is mounted on the test tube mounting seat by the clamping device outside the test tube, the case where the paper sheet or the like can be placed inside the clamping device, and the test piece can be used to detect whether the moisture in the test tube is blown dry.
(2) In embodiment 1, the clamping device is used to detachably connect the test tube and the test tube mounting seat, in practice, the test tube and the test tube mounting seat may be detachably connected in the form of a plug, that is, the plug is made of an elastic material, and when the plug is not deformed, the outer diameter of the plug is larger than the inner diameter of the test tube port, but the lower end of the plug is smaller than the inner diameter of the test tube port, so that the test tube can be allowed to be sleeved on the plug. Meanwhile, the stopper does not completely seal the test tube port in the whole circumferential range, but is provided with a gap locally so that liquid in the test tube can be discharged together with gas.
(3) In embodiment 1, the control valve on the row of air-blowing pipes closest to the air inlet is the highest, the air-blowing pipe on the row of air-blowing pipes farthest from the air inlet is the lowest, and actually the air inlet can be arranged at the corner of the test tube mounting seat, and the distribution rule of the positions of the control valves is as follows: the control valve closest to the air inlet is highest, the heights of the two control valves closest to the control valve are inferior, then the heights of the 3 control valves which are obliquely arranged are again, then the heights of the 4 control valves which are obliquely arranged are again, and so on until the control valve farthest from the corner of the air inlet is lowest.
Such modifications and substitutions do not depart from the spirit of the invention.
