Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0025] like figure 1 , figure 2 As shown, an acid rushing device includes a heater 1 , a digestion tube support frame 2 , a suction device 4 , a number of digestion tubes 3 and a number of adaptive heating isolation devices 5 . The digestion tube is a flat-bottomed straight tube.

[0026] The suction device includes an exhaust duct, an outer cover 4.1 with an open lower end, a suction port arranged on the top surface of the outer cover, a suction fan 4.2 arranged on the suction port, and an exhaust duct 4.3 connected to the exhaust port of the suction fan. The cover is a transparent cover. One end of the exhaust duct is connected with the exhaust port of the exhaust fan, and the other end of the exhaust duct is communicated with the outside. The heater and digestion tube support frame are located in the housing.

Abstract

The invention discloses an acid removal device. The acid removal device solves the problem that a solution in a digestion tube is evaporated or coked because of the negligence of an experimenter so that the experiment is failed. The acid removal device comprises multiple digestion tubes, a heater comprising a heating flat plate of which the upper surface is provided with multiple vertical heatingholes, a digestion tube support frame provided with digestion tube vertical guide sleeves corresponding to the multiple vertical heating holes, wherein the digestion tube vertical guide sleeves are located above the corresponding vertical heating holes, and multiple self-adaptive heating isolation devices which are corresponding to the vertical heating holes, wherein the self-adaptive heating isolation device comprises a guide slide block sliding in the vertical heating hole, a reset compression spring between the bottom surface of the vertical heating hole and the guide slide block, a thermalinsulation support plate for supporting the digestion tubes above the guide slide block and a connection rod connecting the guide slide block and the thermal insulation support plate.

Description

technical field [0001] The invention relates to an experimental device, in particular to an acid rushing device. Background technique [0002] Catching acid is an important step in the process of heavy metal detection in samples. The acid rush experiment usually needs to rush the acid solution in the digestion tube to 10~20% of the original volume. The acid rush process usually takes 3-4 hours, which takes a long time, and the acid rush time often varies among multiple digestion tubes. , so the experimenter needs to pay attention to the acid rush process at all times to avoid the digestion tube solution from being evaporated to dryness; but in the actual acid rush process, often due to the negligence of the experimenter, the digestion tube solution is evaporated to dryness or coke, which makes the experiment fail. [0003] On the other hand, the acid vapor volatilized in the process of chasing the acid will also permeate the laboratory, which not only pollutes the laborato...
