The digestion colorimetric pool with the 'gourd' -shaped structure has the functions of adjusting volume, buffering and removing bubbles, so that the digestion colorimetric pool can be normally used in a bumpy environment.
Description
Technical Field
The utility model relates to the field of chemical analysis instruments, in particular to a gourd-shaped digestion colorimetric pool.
Background
The digestion colorimetric pool used on most of the existing analytical instruments is of a straight tube type, in order to ensure enough optical path, the diameter of the straight tube is usually 15-20 mm, the total volume of a sample and a reagent required by the digestion tube is usually 4-10 ml, and the problems of large reagent consumption and large waste liquid amount exist.
ZL2012206488509 patent discloses a cross type integral digestion cuvette. The device specifically comprises a vertical upper pipe, a vertical lower pipe and a transverse pipe which are connected and communicated in a cross shape, wherein the transverse pipe is also used as an optical channel, the left end and the right end of the transverse pipe are respectively sealed with a plane light-transmitting window, the total capacity of samples and reagents required by a digestion pipe is reduced, but the transition of the joint of the transverse pipe and the vertical lower pipe is too small, and when analysis and detection are carried out, residual liquid at the transverse pipe due to large tension is not easy to empty, so that the cleaning is difficult, and the photometric analysis and detection are affected.
When detecting in wave motion or shaking, the optical channel may be not filled with the detection liquid due to the inclination of the digestion tank, thereby affecting photometric detection.
Disclosure of Invention
In order to solve the defects of the existing digestion colorimetric pool, the digestion colorimetric pool which has the functions of adjusting the volume, buffering and removing bubbles and can be normally used in a bumpy environment is provided, wherein an outlet pipe, an upper ball cavity, a vertical upper pipe, a lower ball cavity, a vertical lower pipe and an inlet pipe are communicated from top to bottom; the lower ball cavity is also used as an optical channel; the diameters of the vertical upper pipe and the vertical lower pipe are smaller than the diameters of the upper ball cavity and the lower ball cavity, and the pipe orifices of the outlet pipe and the inlet pipe of the digestion colorimetric pool are provided with threaded sticky interfaces; the vertical upper pipe and the vertical lower pipe are connected with the upper ball cavity and the lower ball cavity in a connecting mode with smooth inner walls; a temperature measuring groove is arranged in the lower ball cavity; and heating wire fixing points are arranged on the peripheries of the vertical upper pipe, the lower ball cavity and the vertical lower pipe.
Further, the diameter of the upper ball cavity is not smaller than 10mm.
Further, the diameter optical path of the lower ball cavity is 10-90 mm.
Further, the digestion colorimetric pool is made of glass or quartz materials.
The utility model has the beneficial effects that:
the digestion colorimetric pool with the calabash structure has the functions of adjusting the volume, buffering and removing bubbles, and particularly can prevent liquid from being sprayed out when being heated. When detecting under the environment of jolting, like pontoon, mobile vehicle monitoring, this vertical upper tube structure of clearing up pond can effectively avoid the optical path detection department of air admission colorimetric pond. Meanwhile, the design of no wedge angle in the cavity of the digestion tank of the calabash structure can drain the liquid in the cavity during cleaning; no bubbles remained during the measurement.

Description of the embodiments
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, but the described embodiments are only some, but not all embodiments of the present invention. All other embodiments, which can be made by a person skilled in the art based on the embodiments of the invention without any inventive effort, fall within the scope of the protection of the invention.
1-2, The digestion colorimetric pool is composed of an outlet pipe (1), an upper ball cavity (2), a vertical upper pipe (3), a lower ball cavity (4), a vertical lower pipe (5) and an inlet pipe (6) which are communicated from top to bottom; the lower ball cavity (4) is also used as an optical channel; the diameters of the vertical upper pipe (3) and the vertical lower pipe (5) are smaller than the diameters of the upper ball cavity (2) and the lower ball cavity (4), and the pipe orifices of the outlet pipe (1) and the inlet pipe (6) of the digestion colorimetric pool are provided with threaded sticky interfaces; a temperature measuring groove (8) is arranged in the lower ball cavity (4); the periphery of the vertical upper pipe (3), the lower ball cavity (4) and the vertical lower pipe (5) is provided with a heating wire fixing point (7); the vertical upper pipe (3) and the vertical lower pipe (5) are connected with the upper ball cavity (2) and the lower ball cavity (4) in a connecting mode with smooth inner walls, so that liquid in the cavities is discharged when the upper ball cavity and the lower ball cavity are cleaned; no bubbles remained during the measurement.
As shown in fig. 3-4, in actual field application, when the digestion cuvette of the utility model tilts leftwards or rightwards under a bumpy environment condition, the liquid level in the digestion cuvette is still higher than the lower sphere light channel, and the situation that the digestion cuvette is not fully filled with detection liquid can not occur, so that photometric analysis detection is affected.
