Description

Technical Field

[0001] The utility model relates to the technical field of acid-removing devices, in particular to an acid-removing device used for digestion experiments. Background Art

[0002] Acid removal is a sample pretreatment technique used in chemical analysis, primarily to remove excess acid or solvent from a sample to facilitate subsequent analysis and testing. The primary purpose of acid removal is to remove excess acid or solvent from the sample through heating and evaporation, rendering the sample suitable for analysis. This method is widely used in heavy metal and trace element analysis of samples such as food, pharmaceuticals, and soil.

[0003] Traditional acid-removing equipment generally places the solution in the holes of an aluminum alloy plate by placing the digestion tube, and uses heating of the aluminum alloy plate to remove the acid. The aluminum alloy plate is generally evenly provided with multiple groups of tube holes. Although multiple groups of digestion tubes can be heated simultaneously, the entire aluminum alloy plate still needs to be heated when heating a single digestion tube, resulting in energy waste. It is also impossible to achieve different heating times for digestion tubes at different positions. In actual use, there is still a certain inconvenience. Therefore, there is an urgent need for an acid-removing device for digestion experiments to solve the above problems. Utility Model Content

[0006] The air extraction mechanism is arranged on the top of the lifting plate.

[0007] To implement the above technical solution, resin insulation boards are used to insulate each heating aluminum alloy plate segment. In combination with electric heating plates, different segments can be heated separately, so that the device can heat specific positions of the heating aluminum alloy plate. Compared with the existing technology, the device can heat a single digestion tube separately, reduce capacity loss, and allow different digestion tubes to obtain different heating times.

[0008] Furthermore, a mounting groove is provided at the top of the acid remover, and the electric heating plate is located at the bottom of the mounting groove. The heating aluminum alloy plate is inserted into the mounting groove, and when the bottom of the heating aluminum alloy plate is in contact with the electric heating plate, the bottom of the lifting plate is in contact with the acid remover.

[0009] The implementation of the above technical solution makes it easier to clean the heating aluminum alloy plate from the top of the acid remover.

[0010] Furthermore, a clamping bar is connected to the top of the acid remover, and the number of the clamping bar is at least one, and a clamping groove adapted to the clamping bar is provided on the lifting plate at the top of the clamping bar.

[0011] Implementing the above technical solution facilitates improving the stability of the lifting plate.

[0012] Furthermore, both sides of the lifting plate are connected to handles, and the surfaces of the handles are covered with rubber.

[0013] Implementing the above technical solution makes it easier to lift the lifting plate.

[0014] Furthermore, the exhaust mechanism includes a rubber ring strip, and the rubber ring strip is connected to the outer side of the top of the lifting plate.

When the shielding sleeve with ventilation holes on the surface is placed on the lifting plate, the outer side of the shielding sleeve with ventilation holes on the surface is attached to the inner side of the rubber ring strip. The top of the shielding sleeve with ventilation holes on the surface is connected to a bellows, which is connected to an external exhaust device.

[0015] The above technical solution is implemented to facilitate the extraction of the gas generated during the digestion.

[0016] Furthermore, a rubber sleeve is connected to the exhaust end of the bellows for adapting to different exhaust equipment interfaces.

[0017] Implementing the above technical solution can improve the applicability of the bellows.
