Abstract
A novel digestion device is characterized in that: comprises a base, a porous heating furnace and a large-flow fan; the utility model discloses a digestion device's porous heating furnace is last to set up the insulating layer, can effectual isolation porous heating furnace to the first half thermal radiation of sample cell, dispose large-traffic fan simultaneously and blow towards design ground air-blast cold trap in, destroy the first half thermal effect that produces by steam of sample cell and go out the heat from the gas vent area, the uniformity of the sample evaporation condition between the different hole sites of porous heating furnace has been ensured, thereby realized that the sample clears up the parallelism of surplus volume, and then improved iodine analysis's mark curvilinearity, the sample accuracy of testing ground has been improved.
Description
Technical Field
The utility model relates to a novel clear up device.
Background
The purpose of digestion treatment is to destroy organic matter, dissolve suspended solids, oxidize various valence states of the element to be measured into single high valence state or convert into inorganic compounds which are easy to separate. When iodine analysis is carried out, iodine with different forms needs to be converted into iodine with single form through digestion for analysis. The existing digestion device usually adopts a multi-hole graphite furnace to carry out digestion, so that the residual volume of a plurality of samples after digestion is easy to have larger difference due to the difference between hole positions. Thereby bringing certain influence to the test data.
Disclosure of Invention
An object of the utility model is to provide a novel digestion device aims at reducing the volume difference of clearing up between the different hole positions of digestion device, improves the parallelism of clearing up the back sample volume, improves the standard curve nature and the sample inspection degree of accuracy of iodine analysis.
The technical scheme of the invention is as follows: a novel digestion device is characterized in that: comprises a base, a porous heating furnace and a large-flow fan; the porous heating furnace is arranged on the base; the porous heating furnace is provided with a plurality of heating holes for placing sample tubes; a heat insulation layer is arranged above the heating hole and is positioned in the middle of the sample tube; a clapboard is arranged above the heat insulation layer; the clapboard is arranged on the base, is positioned at the upper part of the sample tube and surrounds the heat insulation layer to form an air-blowing cold trap; the large-flow fan is arranged on the base and positioned at one end of the air-blowing cold trap, and the other end of the air-blowing cold trap is provided with an exhaust port.
The utility model has the advantages that: the utility model discloses a set up the insulating layer on digestion unit's the porous heating furnace, can keep apart the heat radiation of porous heating furnace to the first half of sample cell effectively, dispose simultaneously large-traffic fan and blow towards blowing in the air-blast cold trap of design, destroy the first half of sample cell by the heat effect that steam produced, and take away the heat from the gas vent, the uniformity of the sample evaporation condition between the different hole sites of porous heating furnace has been ensured, thereby realized that the sample clears up the parallelism of surplus volume, and then improved iodine analysis's mark curvilinearity, the degree of accuracy that has improved sample detection.

Detailed Description
As shown in the figure: a novel digestion device is characterized in that: comprises a base 1, a porous heating furnace 2 and a large-flow fan 3; the porous heating furnace 2 is arranged on the base 1; the porous heating furnace 2 is provided with a plurality of heating holes 21 for placing the sample tubes 4; a heat insulation layer 22 is arranged above the heating hole 21 and is positioned in the middle of the sample tube 4; a partition plate 5 is arranged above the heat insulation layer 22; the partition plate 5 is arranged on the base 1, is positioned at the upper part of the sample tube 4, and forms an air-blowing cold trap 6 with the heat insulation layer 22 in an enclosing manner; the large-flow fan 3 is arranged on the base 1 and located at one end of the air-blowing cold trap 6, and an exhaust port 8 is formed in the other end of the air-blowing cold trap 6.
The utility model discloses ground theory of operation: the method is characterized in that a porous heating furnace 2 is adopted to heat and digest batch sample tubes 4 filled with samples, the lower half parts of the sample tubes 4 are inserted into heating holes 21 of the porous heating furnace 2, and a heat insulation layer 22 is arranged in the middle of the sample tubes 4, so that heat radiation of the porous heating furnace 2 to the upper half parts of the sample tubes 4 can be effectively isolated. The heating effect produced in the upper half of the sample tubes 4 thus leaves the vapour produced by evaporation of the sample in each sample tube 4. At this time, the temperature of the central position of the porous heating furnace 2 is higher than that of the surrounding, and if the sample is not processed, the central position of the digestion residual volume of the sample in the sample tube 4 is less than that of the surrounding. In order to enable the digestion residual volume in each sample tube 4 to be consistent, a partition plate 5 is arranged at the upper part of each sample tube 4, an air-blowing cold trap 6 is enclosed between the partition plate 5 and a heat insulation layer 22, air is blown into the air-blowing cold trap 6 through a large-flow fan 3 arranged at one end of the air-blowing cold trap 6, the upper half part of each sample tube 4 can be damaged by the heat effect generated by steam through cold air at room temperature, heat is taken out from an air outlet 8, the evaporation amount of samples in the sample tubes 4 at the center position and the periphery is close to each other, and therefore the volume parallelism after multiple samples are digested is achieved.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
