Description

Technical Field

[0001] The utility model relates to a water bath heating device, in particular to a water bath heating device used for soil heavy metal detection. Background Art

[0002] When testing for heavy metals in soil, you first need to use mixed acid to reduce the soil. In order to improve the reduction efficiency, water bath heating is usually used. Because it is a strong acid reduction, foam overflow often occurs during the reaction process. Although the lid on the top of the existing heating box has the function of collecting overflowed liquid, its role is to serve as an insurance. All overflows will gather on the lid, so it is impossible to distinguish and recycle for testing, which will affect the best detection accuracy. In addition, the beaker specifications supported by different water bath heating devices are fixed, and the sample size is different for different heavy metal tests, so the beaker specifications used are also inconsistent, so it is necessary to configure water bath devices of various specifications. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a water bath heating device for soil heavy metal detection, so as to solve the technical problems in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A water bath heating device for soil heavy metal detection comprises a heating box, a cover plate and a water receiving tray. An open water bath is installed in the heating box, and a cover plate is arranged on the top of the water bath. The cover plate is provided with a plurality of notches, and a protruding positioning ring is arranged on the upper side of the notch. The water receiving tray is buckled on the outer edge of the positioning ring through a sleeve ring at the bottom thereof. An insertion hole is provided in the center of the water receiving tray, and a support ring is arranged on the upper side of the insertion hole for supporting the flange of a beaker. The water receiving tray has various specifications, and the inner diameter of the support ring of each specification of the water receiving tray matches the outer diameter of a beaker of the same specification.

[0006] Furthermore, the cover plate is provided with a buckling portion around the edge of the cover plate to buckle with the water bath box, and the cover plate is concave except for the buckling portion and the positioning ring.

[0007] Furthermore, a plurality of pressure relief pipes are dispersedly arranged on the cover plate.

[0008] The utility model is beneficial in that:

[0009] The utility model adds a water receiving tray, which corresponds to the beaker one by one. When the reaction in the beaker is more intense, resulting in overflow of foam, the water receiving tray can collect the overflowed foam. The foam is basically a substance produced after soil reduction, which can be subsequently measured together with the residual substance in the beaker to avoid affecting the accuracy of the detection. Secondly, due to the different sample sizes, the sizes of the beakers are also different. The matching water receiving tray can realize water bath heating of various beakers, which is lower in cost than preparing water bath heating devices of multiple specifications.

[0014] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0015] As shown in the figure:

[0016] A water bath heating device for soil heavy metal detection comprises a heating box body 1, a cover plate 3 and a water receiving tray, wherein an open water bath box 2 is installed in the heating box body 1, and a cover plate 3 is arranged on the top of the water bath box 2; the cover plate 3 is provided with a plurality of notches, and a protruding positioning ring 32 is arranged on the upper side of the notch, and a water receiving tray 4 is buckled on the outer edge of the positioning ring 32 through a sleeve ring 41 at its bottom, and an insertion hole is provided in the center of the water receiving tray 4, and a support ring 42 is arranged on the upper side of the insertion hole for supporting a flange 51 of a beaker 5, wherein the water receiving tray 4 has a plurality of specifications, and the inner diameter of the support ring 42 of each specification of the water receiving tray 4 matches the outer diameter of a beaker 5 of the same specification.

[0017] In the utility model, both the heating box body 1 and the water tank adopt the existing technology, and the main improved part is the cover plate 3, which is consistent with the existing technology. The cover plate 3 of the utility model is also provided with several notches, but the notches are not directly used to install the beaker 5. Instead, a positioning ring 32 is provided on the upper side of the notches for installing the water receiving tray 4, and then the beaker 5 is installed on the support ring 42 of the water receiving tray 4. The water receiving tray 4 has various specifications, and the inner diameter of the support ring 42 of each specification of the water receiving tray 4 matches the outer diameter of the beaker 5 of the same specification.

[0018] The advantages of the above structure are that firstly, a water receiving tray 4 is added, and the water receiving tray 4 corresponds to the beaker 5 one by one. When the reaction in the beaker 5 is more intense, resulting in overflow of foam, the water receiving tray 4 can collect the overflowed foam. The foam is basically a substance produced after soil reduction, which can be subsequently measured together with the residual substance in the beaker 5 to avoid affecting the accuracy of the detection. Secondly, due to the different sample sizes, the sizes of the beakers 5 are also different. The matching water receiving tray 4 can realize water bath heating of various beakers 5, which is lower in cost than preparing water bath heating devices of multiple specifications.

[0019] As an optimized technical solution, a buckling portion 31 is arranged around the edge of the cover plate 3 to buckle with the water bath box 2. Except for the buckling portion 31 and the positioning ring 32, the cover plate 3 is concave, which can serve as a final insurance. Once the water receiving tray 4 overflows, the overflowed material can be collected to avoid damage to the equipment by strong acid. In order to facilitate the exhaust of water vapor, a plurality of pressure relief pipes can be dispersedly arranged on the cover plate 3.

[0020] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
