Automatic acid cleaning device and method for glassware

Abstract

The invention discloses an automatic acid cleaning device and method for glassware. The automatic acid cleaning device comprises an acid steaming cleaner and a condensation bin, the acid steaming cleaner comprises a cleaning chamber and an acid steam generating chamber arranged below the cleaning chamber, the cleaning chamber is arranged in the condensation bin, a cleaning frame is fixedly arranged in the cleaning chamber, the cleaning frame comprises a supporting plate and a plurality of cleaning pipes arranged above the supporting plate, each cleaning pipe comprises a long cleaning pipe and a short cleaning pipe arranged on the long cleaning pipe in a sleeved mode, an electric heating plate is arranged on the inner bottom surface of the acid steam generating chamber, the bottom of one side of the acid steam generating chamber respectively communicates with an acid liquor conveying pipe, a water conveying pipe and a hot air conveying pipe, the water conveying pipe communicates with the long cleaning pipe, the condensation bin is divided into a cold supply area and a condensation area, and the bottom of one side of the cold supply area sequentially communicates with a second fan and a compressor through a cold air conveying pipe. The device is an automatic device integrating pure water flushing, acid steaming cleaning, ultrapure water flushing and drying, and the workload of operators can be reduced.

Description

technical field [0001] The invention belongs to the technical field of laboratory cleaning, and in particular relates to an automatic acid cleaning device and method for glassware. Background technique [0002] Cleaning glassware is a prerequisite for correct results in experiments, especially cleaning various glassware used for trace analysis is a prudent and important experimental procedure. Because the results of retesting heavy metals are often trace content in mg / kg, and glassware has a certain adsorption effect on heavy metal elements, which will contaminate the sample solution after being adsorbed by glassware, resulting in high or even doubled measured values. Therefore, before trace analysis, it is necessary to clean the impurities of trace metal elements on the glassware. The traditional cleaning method is soaking in hot acid for several hours or cleaning with ultrasonic waves. In order to avoid cross-contamination, the acid needs to be replaced regularly. This me...

AI Technical Summary

Problems solved by technology

The traditional cleaning method is soaking in hot acid for several hours or cleaning with ultrasonic waves. In order to avoid cross-contamination, the acid needs to be replaced regularly. This method not only has low efficiency and high acid consumption, but also requires manual operation. Exposure poses certain safety hazards to operators

[0003] At present, there are also special acid steam cleaning devices available, but they are all non-circulating acid steam structures, and the acid consumption is still large

And before the acid steam cleaning operation, it is necessary to manually wash off the water-soluble substances and adhered dust on the glassware one by one with pure water; Drying glassware in advanced drying equipment is cumbersome and inefficient, and it is easy to bring certain safety hazards to operators during the operation process.

In addition, when drying in a traditional blast drying oven, it is often necessary to open and close the box door to dry utensils for other purposes, and the incoming air is not strictly filtered and purified, and it often faces secondary problems caused by other utensils or unclean air. secondary pollution
