Abstract
The utility model discloses a full automatic pressure blowing concentrator which comprises a heater, an air supply device and a singlechip, wherein the air supply device comprises a draft tube, a gas guide tube, a needle and a liquid level sensor, the liquid level sensor is fixed with the needle together and used for detecting the liquid level of a sample test tube and feeding the liquid level back to the singlechip, and the singlechip controls the heater and the air supply device to be switched on and off. According to the full automatic pressure blowing concentrator, the liquid level of the sample can be located accurately, so that the heater and the air supply device can be controlled to be switched on and off, the consumption is reduced, and the cost is lowered.
Description
Technical field
The utility model relates to a kind of full-automatic Nitrogen evaporator, belongs to food inspection device technique field.
Background technology
Usually, Nitrogen evaporator is comprised of heating arrangement, sample positioning device and feeder three parts.Nitrogen or air be through behind the feeder, is blown into by wireway and is fixed on the sample positioning device and places sampling receptacle on the heating arrangement, makes that the organic solvent in the sample volatilizees rapidly in the sampling receptacle, thereby realize concentrated to sample.Nitrogen evaporator in the market, its feeder design is reasonable not, can't accurately locate the concentrating degree of sample, heating arrangement and feeder will work on, cause the waste of resource, and each root wireway can not independently control opening and closing, when the laboratory sample negligible amounts, and the waste source of the gas.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of full-automatic Nitrogen evaporator, it is simple and reasonable, have one can test sample test tube liquid level liquid level sensor, it feeds back to single-chip microcomputer with information, the switch of Single-chip Controlling heating arrangement and feeder, economize on resources, reduce cost.
In order to address the above problem, the technical solution of the utility model is as follows: full-automatic Nitrogen evaporator, formed by heating arrangement, feeder and single-chip microcomputer, it is characterized in that, feeder is comprised of mozzle, wireway, syringe needle and liquid level sensor, liquid level sensor and syringe needle are fixed together, for detection of the sample tube liquid level and feed back to single-chip microcomputer, the switch of Single-chip Controlling heating arrangement and feeder.
Above-mentioned sample tube is fixed on the heating arrangement.
Above-mentioned heating arrangement can be electric heater unit or water bath heating device.
Above-mentioned heating arrangement, feeder are provided with solenoid valve, and single-chip microcomputer is by switch control heating arrangement and the feeder of control solenoid valve.
Described liquid level sensor should be used contactless liquid level sensor, when nitrogen blows, syringe needle can not be contacted liquid level.
Nitrogen evaporator generally is provided with a plurality of wireways, and requirement that can be is per sample controlled respectively each wireway nitrogen flow by solenoid valve.
The utility model beneficial effect: the full-automatic Nitrogen evaporator of the utility model, simple and reasonable, liquid level sensor wherein can accurately be responded to the sample tube liquid level, and information fed back to single-chip microcomputer, switch by Single-chip Controlling heating arrangement and feeder, can reduce like this being blown into of unnecessary nitrogen and scattering and disappearing of heat, save the energy, reduce cost.
Description of drawings
Fig. 1 is structural representation of the present utility model (1, feeder, 2, wireway, 3, syringe needle, 4, sample tube, 5, heating arrangement, 6, liquid level sensor, 7, mozzle)
Embodiment
Below in conjunction with Figure of description the utility model is further specified.
A kind of full-automatic Nitrogen evaporator comprises heating arrangement 5, feeder 1 and single-chip microcomputer.
As shown in Figure 1, described feeder comprises that mozzle 7, syringe needle 3, wireway 2 and liquid level sensor 6 form, described liquid level sensor 6 is fixed together with syringe needle 3, for detection of the sample tube liquid level and feed back to single-chip microcomputer, the switch of Single-chip Controlling heating arrangement 5 and feeder 1.When nitrogen passes through mozzle 7, shunted by the venthole on the mozzle 7, enter in each wireway 2, be blown into sample tube 4 by syringe needle 3 again, the liquid level that level sensor 6 on the syringe needle 3 can accurately be responded in the sample tube changes, and level sensor 6 can feed back to single-chip microcomputer with this information, by the switch of Single-chip Controlling heating arrangement and feeder solenoid valve, make it to close, in order to avoid waste gas.
