Background technology
At present, photoelectric colorimetry is widely used in chemical analysis, and is particularly in the water quality monitoring field, easy and simple to handle, rapid, reliable.This method adopts chemical reagent that solution is developed the color, after the irradiation of specific wavelength monochromatic light, measure the absorbance of digestion solution with the photoelectric color comparator device, then with the contrast of pre-rendered standard working curve, obtain as calculated concentration or the content of the tested component of sample.In order to raise the efficiency and to reduce the error that operating process brings, the monoblock types that adopt are cleared up colorimetric pool more at present, clear up reaction and During Illumination and complete in clearing up colorimetric pool same.The main body that existing monoblock type is cleared up colorimetric pool mostly is the consistent clear glass straight tube of diameter, clear up reaction in sample and reagent mixed liquor access tube, generation along with reactant, solution develops the color gradually, reaction is completed, the monochromatic light of certain wavelength is radially injected the glass straight tube, and incident light sees through the colored solutions in pipe, then records the concentration data of tested component by photoelectric color comparator.Because the light path of sample solution illumination is generally 12～20 mm, it is consistent with light path that straight pipe type is cleared up the whole caliber of colorimetric pool, the volume that causes clearing up colorimetric pool is very large, the needed reagent total amount of unitary determination is at least more than 4 mL, many persons can reach 10 mL, not only waste reagent, and the waste liquid of discharging after analyzing also causes larger secondary pollution.In addition, stir because digestion process need adopt air-blowing, some reaction needs heat temperature raising, and the steam after the microgas that blasts and solution heating constantly increases the interior pressure of airtight colorimetric pool.For tubular body, its bear pressure be proportional to the pipe inside radius square; So the colorimetric pool internal diameter is larger, withstand voltage properties is lower, and the possibility that explosion occurs is higher, in case explosion occurs, consequence is quite serious.In order to take the problem of withstand voltage of straight pipe type digestion pool main body into account, generally can reduce the diameter of body, so that effectively light path is not enough as far as possible, impact detects the degree of accuracy of data.
Summary of the invention
Clear up for present straight tube-like the defects that colorimetric pool exists, the purpose of this utility model is to provide a kind of high pressure resistant, low reagent consumption, highly sensitive cross integral body to clear up colorimetric pool.
The cross integral body of the utility model is cleared up colorimetric pool, by vertically upper pipe, vertical lower pipe are " ten " font and are connected and communicate with transverse pipe; Described transverse pipe is held concurrently and is optical channel, and the plane light-transmission window has been sealed respectively at two ends, transverse pipe left and right; The diameter of described vertically upper pipe and vertically lower pipe is all much smaller than the length of transverse pipe.
Suitable for reading and the end opening vertical lower pipe of described vertically upper pipe is complementary with internal diameter and the external pipeline that dwindles.
Suitable for reading and the end opening vertical lower pipe of described vertically upper pipe is equipped with obstruction, obstruction is provided with the jack of small-bore, vertically lower pipe is pegged graft with feed tube by the jack that stops up and is connected, and vertically upper pipe is pegged graft with gas outlet by the jack that stops up and is connected, and gas outlet is connected with vent valve.
Suitable for reading and the end opening vertical lower pipe of described vertically upper pipe is internal diameter and dwindles and be respectively equipped with screw thread, vertically goes up pipe thread to be connected with gas outlet, and gas outlet is connected with vent valve; Vertically lower pipe is connected with feed tube by screw thread.
Described vertical lower pipe and transverse pipe join the position towards transverse pipe direction flaring, and inwall is the cambered surface transition.
Described vertical lower pipe is connected with the temperature sensor intubate.
The outer wall of described lower pipe is provided with the heating wire cable clamping interface.
The outer wall of lower pipe and upper pipe is equipped with the fixedly binding ring of heating wire termination.
Cross integral body is cleared up colorimetric pool and is made by glass or quartz material.
Originally clear up in colorimetric pool, except the transverse pipe inner length as optical channel need satisfy the light path needs, other each several part internal diameter all can obviously reduce, this reduces the total measurement (volume) of clearing up colorimetric pool, for detection of sample size and reagent consumption significantly reduce, be approximately routine clear up colorimetric pool 1/3～1/6; And, after the caliber of clearing up colorimetric pool reduces, withstand voltage properties also significantly improves, the pressure that bear inside can reach routine and clear up more than 4 times of colorimetric pool, when originally clearing up the colorimetric pool design, needn't reduce the due length of optical channel in order to take the main body problem of withstand voltage into account, Decrepitation Phenomena can not occur, both safety can be guaranteed again effective light path of incident light, and the colorimetric pool of clearing up that the sensitivity of detection is more conventional improves a lot 15～20%.
