Device and method for preparing electrolyte standard sample on site

Abstract

The invention provides a device and a method for preparing an electrolyte standard sample on site, an electrolyte contained in a standard sample box is pressed into the electrolyte standard sample by adopting a pressing die handle, the standard sample box comprises a bottom die with a limiting table, and a spring and a standard sample ring are sleeved on the bottom die; an opening space jointly defined by the inner wall of the standard sample ring and the top face of the bottom die is used for containing electrolyte, the upper end of the spring abuts against the standard sample ring, the lower end of the spring abuts against the limiting table, the standard sample ring can move downwards along the bottom die after being pressed, and after pressure applied to the standard sample ring is removed, the standard sample ring is reset under the elastic force effect of the spring. The method comprises the following steps: placing a standard sample box on a movable tray, pouring fluid or semi-fluid electrolyte into an open space of the standard sample box, moving the movable tray to the position under a pressing die handle, and pressing a standard sample ring of the standard sample box by adopting the pressing die handle. According to the invention, the technical problems of high cost, complex standard sample preparation process, dust pollution and the like of the traditional electrolyte standard sample preparation method are solved by using an extremely simple and ingenious technical route and device.

Description

technical field [0001] The invention belongs to the technical field of preparation of electrolyte standard samples, and in particular relates to a device for preparing electrolyte standard samples on site and a method for preparing electrolyte standard samples. Background technique [0002] There are usually two technical routes for the preparation of electrolyte standard samples in electrolytic aluminum production units: one is that the operator scoops up the sample preparation melt (electrolyte) one by one in the production workshop and puts it into the sample box, and waits for the sample preparation melt to solidify in the holding box Then transfer it to the testing center and grind it into powder, and then take the powder according to the amount and press it into tablets (the compressed electrolyte tablet is called the electrolyte standard sample); the second is to use automatic sample preparation and testing equipment to take samples in the production workshop and grind...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a device for preparing electrolyte standard samples on site and a method for making electrolyte standard samples, which not only fundamentally solve the problem of dust pollution generated when preparing electrolyte standard samples, but also greatly reduce the required labor force. It also has the advantages of simple procedure for preparing electrolyte standard samples, high efficiency, good flexibility, etc.
