Embodiment 1

[0039] Such as Figure 1-Figure 2 As shown, the nitrogen blowing instrument includes a base 20 and a test tube mounting base 10, a water bath is provided in the base 20, and the test tube mounting base 10 can be equipped with test tubes 90 in a matrix distribution in a detachable manner, and the test tube mounting base 10 is detachable. Installed on the base 20 in the same way, the test tube mounting base 10 is provided with a ventilation pipeline network 11 inside, and the ventilation pipeline network 11 has an air inlet 14, and the air inlet 14 is used to communicate with the gas source 40, and the ventilation pipeline network 11 is connected with multiple A blowing pipe 12 communicates, and each blowing pipe 12 is used for cleaning a test tube 90, and each blowing pipe 12 is connected with a control valve. Wherein, each test tube mounting seat 10 can be provided with 8*10=80 positions for installing test tubes 90 . The test tube 90 can be installed in the manner of clampin...

Embodiment 2

[0050] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the air inlet 14 is arranged on the side of the test tube mounting seat 10, and the control valve is a manual control valve 13. As the distance between the blowing pipe 12 and the air inlet 14 increases , the position of the control valve on each blowing pipe 12 gradually decreases.

[0051] By setting the height of the manual valve to be positively or negatively related to the distance from the air inlet 14 of the air blow pipe 12, the characteristics of high air pressure and large air volume of the air blow pipe 12 that is closer to the inlet can be used to dry part of the test tubes 90 first, and can be closed first. This part blows air tube 12, thus concentrates the wind volume of remaining air blowing tube 12 to the air blowing tube 12 that has not yet dried up corresponding test tube 90, to improve the operation efficiency of drying up all test tubes 90 on the...

Embodiment 3

[0059] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the air inlet 14 is arranged on the top of the test tube mounting seat 10, the control valve is installed on the top of the test tube mounting seat 10, and the control valve has a hole that can go deep into the blowing pipe 12. The valve core, and the air blowing pipe 12 has different ventilation areas when the valve core is in different positions.

[0060] By installing the air inlet 14 and the control valve on the top of the test tube mounting seat 10, the blowing pipe 12 of the test tube 90 that has been dried earlier can be closed by the operator above, so as to save the air flow, and the remaining air can be applied to the test tube. In the remaining test tube 90 that has not been blown dry, thereby saving the air consumption.

[0061] Specifically, on the outside of each blowing pipe 12, the test tube mount 10 is provided with a test tube 90 clamping device, and the test t...

Abstract

The invention provides a nitrogen blowing instrument and a nitrogen blowing instrument test tube mounting seat and relates to the technical field of food detection devices. The nitrogen blowing instrument includes a base and a test tube mounting base. The test tube mounting base is detachably provided with test tubes in a matrix. The test tube mounting base is detachably mounted on the base. A ventilation pipe network is arranged in the test tube mounting base and is provided with an air inlet. The air inlet is communicated with a gas source. The ventilation pipe network is communicated with multiple gas blowing pipes. Each one of the gas blowing pipes is used for cleaning one test tube. Each one gas blowing pipe is connected to a control valve. The nitrogen blowing instrument solves the technical problem that a large number of test tubes in the existing nitrogen blowing instrument cannot be fast replaced.

Description

technical field [0001] The invention relates to the technical field of food testing equipment, in particular to a nitrogen blowing instrument and a test tube mounting seat for the nitrogen blowing instrument. Background technique [0002] Nitrogen blowing instrument is also called nitrogen blowing dry instrument, automatic fast concentrator, etc. This instrument blows nitrogen gas to the surface of the heated sample quickly, continuously and controllably, so that the water in the sample to be treated can be evaporated and separated quickly, so as to realize the sample At the same time, the instrument can maintain the purity of the sample, so as to achieve the effect of rapid separation and purification. The nitrogen blowing instrument is easy to operate, so it has been widely used, but the capacity of the test tube plate of the existing nitrogen blowing instrument is limited. Only a limited number of samples can be processed, and the test tubes can only be replaced one by on...
