Description

Technical Field

[0001] The utility model belongs to a cleaning device for a glass measuring vessel, in particular to an acid box for chemical experiments. Background Art

[0002] In the daily testing environment of chemical laboratories, some glass measuring vessels, such as volumetric flasks of various specifications and models, are often frequently used. These glass measuring vessels are often used to dissolve some materials in chemical laboratories, and some concentrated acid is often added during the dissolution process to ensure the full dissolution of the sample. After the sample is completely dissolved, the laboratory staff will send the glass measuring vessels with acid solution to the corresponding equipment for component detection and analysis. After the glass measuring vessels in the laboratory are used, if they are used for routine element detection, they are often repeatedly cleaned with tap water after use. Generally speaking, they can be reused after being cleaned. However, for the determination of the content of trace elements in some materials, there are higher requirements for the cleanliness of the glass measuring vessels. The requirements for all links in the whole process in the experiment become very strict, and even slight influences cannot be brought into the experiment. Therefore, it is impossible to clean the glass measuring vessel directly by rinsing it with water. At present, a method recognized by the laboratory is to soak the glass measuring vessel in acid for several hours, and then remove the impurities in the bottle that are difficult to clean with acid before using it. However, if the glass measuring vessel is directly placed in the acid tank for soaking, it is not only inconvenient for the experimenter to operate, but also he has to reach into the acid tank to take out the glass measuring vessel, which may cause potential safety hazards. Therefore, it is very necessary for the laboratory to design a device that allows the operator to safely and conveniently take out the glass measuring vessel soaked in acid. Utility Model Content

[0003] The utility model aims to provide an acid box for chemical experiments, which can facilitate operators to safely and conveniently take out and put glass measuring vessels after acid washing in the box.

[0004] The technical solution is as follows:

[0005] The invention discloses an acid box for chemical experiments, comprising: a box body, a circular sliding button, a lifting rod, a porous acid-proof sandwich plate, an acid-base tie, an acid-proof polytetrafluoroethylene packing rope, and a fixing plate; the top of the box body is open, and mounting holes are respectively arranged on the upper parts of the outer walls on both sides; the ends of two fixing plates are respectively connected to the outer walls on both sides of the box body, a collar is arranged on the top of the fixing plate, and the circular sliding button is installed on the fixing plate; the porous acid-proof sandwich plate is placed inside the box body, and the porous acid-proof sandwich plate is provided with a plurality of grids; the acid-base tie is connected to the outer walls on both sides of the porous acid-proof sandwich plate, the polytetrafluoroethylene packing rope is passed through the mounting hole and the collar, one end of the polytetrafluoroethylene packing rope is connected to the acid-base tie, and the other end passes through the circular sliding button and is connected to one end of the lifting rod.

[0006] Furthermore, the end of the fixing plate is connected to the corner of the box.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] The utility model is easy to use and can help operators to safely and conveniently take out and put the pickled glass measuring device in the box.

[0009] The utility model is easy to operate and can be operated with one hand, and the glass measuring vessel soaked in concentrated acid can be directly taken and placed.

[0010] The device puts an acid-base tie on the middle position of both sides of the acid-proof sandwich plate and uses an acid-proof PTFE packing rope to firmly cover it. The PTFE packing rope extends to the edge of the box and is connected to a fixed plate. At the same time, a round sliding button is installed at the front end of the fixed plate and a lifting rod is vertically installed on its side. The operator pulls the lifting rod outside the box to drive the sandwich plate with holes placed in the box to raise it to a certain position. The sandwich plate is designed to stop at a height of 10 cm from the bottom of the box. At this time, the concentrated acid reagent and the soaked glass measuring vessel will be separated from each other due to gravity, so that the operator can use the glass measuring vessel safely and conveniently.
