Description

Quick analytical equipment of chemistry titration Technical Field The utility model relates to the field of chemical titration devices, in particular to a chemical titration rapid analysis device. Background The accurate determination of the content of heavy metals in soil is a key link for evaluating the pollution degree of soil and making a scientific treatment scheme. Chemical titration analysis plays an important role in heavy metal soil pollution detection as a classical and widely applied quantitative analysis method. Through chemical titration, the concentration of various heavy metal ions in a soil sample can be accurately measured, key data support is provided for soil pollution control and environmental protection, and the method has great significance in maintaining ecological balance and guaranteeing agricultural sustainable development. Currently, there are a number of problems with conventional chemical titration devices used in the detection of heavy metal soil pollution. In terms of titration accuracy, due to the fact that the soil sample detection environment is complex, laboratory space is limited, personnel and equipment are frequent to move, and a traditional device lacks an effective container fixing structure. During titration, the container is extremely susceptible to vibration interference, such as normal operation vibration of instruments and equipment, ground vibration generated by walking of personnel and the like. These vibrations can cause deviations in the position of the drops of titration into the container, thereby affecting accurate determination of the endpoint of the titration. For example, when detecting the content of heavy metals such as lead and cadmium in a soil sample, a small error in determining the titration end point may cause misdetermination of the soil pollution degree, so that the follow-up treatment measures are not targeted. In terms of titration efficiency, the operation flow of the traditional device is complex. The inspector needs to manually squeeze the dropper or operate the complicated separating funnel to control the flow rate and the flow of the titration liquid, so that the operation is inconvenient, and quick titration is difficult to realize. When facing a large amount of soil sample detection tasks, the inefficiency of manual operation can seriously delay the detection progress, can not in time provide data support for soil pollution treatment, influences the timeliness of treatment work, and from the durability, most of chemical reagents for heavy metal soil pollution detection have corrosiveness. Parts of conventional titration apparatuses which are in contact with these reagents, such as pistons, valves, etc. made of metal, are extremely susceptible to corrosion during long-term use. Once the parts are rusted and worn, the tightness of the device is reduced, so that reagent leakage and titration accuracy are further reduced, and even the device cannot be used normally. This not only increases maintenance costs and replacement frequency of the apparatus, but may also cause interruption and inaccuracy of the detection data. Therefore, it is urgent to develop a chemical titration rapid analysis apparatus for heavy metal soil pollution detection with high accuracy, high efficiency and durability.
