Abstract
The utility model discloses a flowing solution mixing and heating device, in particular to a mixing and heating apparatus of sample and reagent in the flow injection analysis. The device is composed of a shell body, a temperature sensing sensor, a heating element, a control circuit board, a solution flow channel composed of a solution transfer pipe, a mixed liquid transfer pipe and a tee mixing tank, a sealing plate, a pressing plate and a temperature-sensing cover. The control circuit board controls the opening of the heating element after acquiring the information of the temperature sensing sensor so as to satisfy the temperature needed by the reaction. The sample solution to be tested is input from the solution transfer pipe and enters the tee mixing tank via the solution transfer pipe, meanwhile, the chemical reagent flows in from the middle end of the tee mixing tank and flows out through the output end of the mixed liquid transfer pipe after mixing and reaction. The utility model can be mounted on a testing apparatus, and is suitable for the on-site online analysis and detection.
Description
Technical field:
The utility model relate to that a kind of fluent solution mixes and heater, especially Flow Injection Analysis in the mixing and the device of heating of sample and reagent.
Background technology:
Flow Injection Analysis (FIA) is a kind of alternative manual operations, realizes the automatic control technology of on-line automatic analysis, sample introduction.For using spectrophotometer to carry out the FIA system of signal detection, usually need be in flow process, make one or more chemical reagent that contain sample solution and injection, produce physical mixed and chemical reaction, and generate the compound that can quantitatively be detected by spectrophotometer, thereby finish mensuration.In this process,, need the sample that flow be mixed with reagent solution usually for the chemical reaction velocity that improves solution system and the stability of analytic signal, heating or constant temperature handles, and makes it make chemical reaction and finish mensuration under the temperature environment of setting.Now to the sample that flows mix with reagent solution, heating or constant temperature processing, two devices of general employing are realized, one of them device is that sample solution is mixed with one or more chemical reagent of injection, and another device is that the solution and the chemical reagent that will mix are done heating or constant temperature processing.During use, need to install connecting line between the stream oriented device, last device device after mixed solution can be delivered to by pipeline does heating or constant temperature is handled, to finish the chemical reaction to solution system.Though adopt this method also can carry out Flow Injection Analysis, in use have the following disadvantages: the first is made troubles to use owing to also connecting line need be installed in the separate use between the stream oriented device; It two is that temperature control device can only be the open type device generally, be unfavorable for carrying, and thermal losses is big, and heat transfer efficiency is low, has increased analysis time; It three is that the combined volume of stream oriented device is bigger, can not be installed in the analytical instrument, detects so be not suitable for on-the-spot on-line analysis.
Summary of the invention:
The purpose of this utility model is that a kind of fluent solution mixes and heater, and this device can be installed in the analytical instrument, has the advantage that compact conformation, pipeline connect simple, little, the easy carrying of volume, efficiency of heating surface height and temperature-controlled precision height.
For achieving the above object, the utility model comprises: housing, the temperature-sensitive sensor, heating element heater, control circuit board, housing is formed a rectangular-shaped cavity body by holder and case, control circuit board is installed on the outer holder of housing, heating element heater is installed on the interior holder of housing, it is characterized in that: also be included in one group of test solution flow channel is housed in the housing at least, the test solution flow channel is by the solution transfer tube, mixed liquor transfer tube and threeway mixing channel are formed, the output of solution transfer tube connects the threeway mixing channel, the input of mixed liquor transfer tube connects the threeway mixing channel, the input of solution transfer tube, the intermediate ends of the output of mixed liquor transfer tube and threeway mixing channel passes housing and stretches out, sealing plate and pressing plate are housed respectively outside housing, the temperature-sensitive cover is housed on the holder of housing, and the temperature-sensitive sensor is positioned at housing and is fixed on temperature-sensitive outward and puts.
For making the test solution thermally equivalent, the intermediate ends of above-mentioned solution transfer tube and mixed liquor transfer tube is curled into spring-like.
The utility model is integrated the original stream oriented device that needs to mix, heat owing to adopted said structure, compares with original device to have the following advantages: 1) avoided the pipeline between the former stream oriented device to be connected, easy and simple to handle being difficult for made mistakes; 2) compact conformation, volume is little, can be installed in easily in the analytical instrument, is fit to on-the-spot on-line analysis and detects; 3) Feng Bi heating system can improve the thermal efficiency, shortens preheating time, makes analytical equipment can enter normal operating conditions as early as possible.In addition, also has the advantage of accuracy of temperature control height through trying out.
Description of drawings:
Fig. 1, be cutaway view of the present utility model.
The specific embodiment:
By shown in Figure 1, housing 1 is formed a rectangular-shaped cavity body by holder 11 and case 14, and control circuit board 13 is installed on the outer holder 11 of housing 1, and heating element heater 12 is installed on the interior holder 11 of housing 1.In housing 1, one or more groups test solution flow channel can be installed according to actual needs, the test solution flow channel is made up of solution transfer tube 2, mixed liquor transfer tube 3 and threeway mixing channel 9, the output of solution transfer tube 2 connects threeway mixing channel 9, the input of mixed liquor transfer tube 3 connects threeway mixing channel 9, and the intermediate ends 6 of the input 4 of solution transfer tube 2, the output 5 of mixed liquor transfer tube 3 and threeway mixing channel 9 passes housing 1 and stretches out.The intermediate ends of solution transfer tube 2 and mixed liquor transfer tube 3 is curled into spring-like.Sealing plate 8 and pressing plate 7 are housed respectively outside housing 1, temperature-sensitive cover 15 is housed on the holder 11 of housing 1, temperature-sensitive sensor 10 is positioned at housing 1 outer being fixed on the temperature-sensitive cover 15.Holder 11 is connected on the tester.During use, sample solution is from input 4 inputs of solution transfer tube 2, enter threeway mixing channel 9 through solution transfer tube 2, simultaneously, one or more chemical reagent enter from the intermediate ends 6 of threeway mixing channel 9, sample solution mixes with chemical reagent in threeway mixing channel 9, enters in the mixed liquor transfer tube 3 through the input of mixed solution by mixed liquor transfer tube 3, and the output 5 from mixed liquor transfer tube 3 flows out at last.Fill with heat transfer medium in the cavity of housing 1, control circuit board 13 receives the temperature signal of temperature-sensitive sensor 10, and according to the temperature conditions in housing 1 cavity, the switch of control heating element heater 12 is to satisfy the needs of chemical reaction.
