Abstract
The utility model discloses a nitrogen blowing instrument preheating distribution device which structurally comprises a bracket, a base and a sample test tube, wherein the base is arranged at the bottom of the bracket, a heating block is arranged at the top of the bracket, the plurality of sample test tubes are arranged on the heating block uniformly and are correspondingly matched with blowing needles arranged at the bottom of a manifold block, and the upper part of the manifold block is communicated with an air inlet connector. Compared with the prior art, the nitrogen blowing instrument preheating distribution device has characteristics of compact structure, uniform and reasonable air distribution, high controllability on preheating temperature, and less heat loss, solves the problems of uneven airflow distribution and inaccurate preheating temperature, and improves the test accuracy.
Description
Technical field
The utility model relates to and a kind of the sample organic solvent is carried out fast the equipment that concentrates, the air distributing device of Nitrogen evaporator preheating specifically.
Background technology
Being used for fields such as agricultural residual evaluation, medicine, public security in the market mainly is to realize distribution and preheating as follows to the fixed air pin type Nitrogen evaporator that the sample organic solvent carries out concentrating fast: nitrogen advances an air chamber to gas delivery by gas piping again through preheating earlier, be uniform-distribution with venthole on the air chamber and connecting air tube, such design has following shortcoming: 1) nitrogen arrives the blow needle outlet again from preheating very big thermal loss, the temperature of preheating shows and the actual temperature of blow needle outlet nitrogen has very big error, causes distortion; 2) to enter behind the air cavity be not to be evenly distributed on air chamber to nitrogen, and the result who causes is exactly that the size of the airshed of each air tube has very big difference, makes sample in the process that heating nitrogen blows, and the evaporate to dryness speed difference of sample is unfavorable for that last result detects.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides a kind of distribution evenly reasonable, the Nitrogen evaporator preheating air distributing device that the preheat temperature controllability is high.
The technical scheme that its technical matters that solves the utility model adopts is: this preheating air distributing device comprises support, base and sample tube, the bottom of support is provided with base, the top of support is provided with heat block, evenly be placed with a plurality of sample tubes on the heat block, sample tube and the blow needle corresponding matching that is installed in the manifold blocks bottom, the top of manifold blocks is communicated with inlet suction port.
S shape air flue is set in the described manifold blocks, in the air flue on manifold blocks top heating tube is installed.
Nitrogen evaporator preheating air distributing device of the present utility model is compared with prior art, has compact conformation, and distribution is evenly reasonable, preheat temperature controllability height, the characteristics that thermal loss is few, it is inhomogeneous to have solved distribution of air flow, the problem of preheat temperature distortion has improved the degree of accuracy of experiment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of Nitrogen evaporator preheating air distributing device.
Among the figure: 1, manifold blocks, 2, inlet suction port, 3, blow needle, 4, sample tube, 5, heat block, 6, support, 7, base, 8, heating tube, 9, air flue.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Nitrogen evaporator preheating air distributing device of the present utility model, its structure comprises support 6, base 7 and sample tube 4, the bottom of support 6 is provided with base 7, the top of support 6 is provided with heat block 5, evenly be placed with a plurality of sample tubes 4 on the heat block 5, sample tube 4 and blow needle 3 corresponding matching that are installed in manifold blocks 1 bottom, the top of manifold blocks 1 is communicated with inlet suction port 2, S shape air flue 9 is set in the manifold blocks 1, in the air flue 9 on manifold blocks 1 top heating tube 8 is installed.
Nitrogen enters into manifold blocks 1 from inlet suction port 2, nitrogen flows from top to bottom along the S shape air flue 9 in the manifold blocks 1, nitrogen is in air flue 9 flow process, constantly be heated pipe 8 preheatings, when air-flow arrived foot passage, nitrogen reached desired temperature substantially, and air-flow blows out along blow needle 3, enter in the sample tube 4, realize that sample dries up concentrated in batches.
Its processing and fabricating of Nitrogen evaporator preheating air distributing device of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.The material of manifold blocks 1 is an aluminum or aluminum alloy.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
