a filter dispenser

Abstract

The invention relates to a filter liquid separator which comprises a cup body with a material inlet formed in the top end and a liquid outlet formed in the bottom, a filter net group which is located in the cup body and separates the material inlet from a material outlet, a transparent pipe which extends from the liquid outlet to a direction deviating from the material inlet, and a valve mounted on the transparent pipe, wherein a filtrate cavity for containing filtrate is formed between the filter net group and the bottom of the cup body in the cup body. By the adoption of the filter liquid separator for filtering and liquid separation operations, the total time length for filtering and liquid separation is shortened; furthermore, the filtration and the liquid separation are both realized in the filter liquid separator; the filtrate is low in loss; and an obtained test result is more accurate.

Description

technical field [0001] The invention relates to an experimental device, in particular to a filter separator. Background technique [0002] Filters are commonly used solid-liquid separation devices in laboratories, and can be divided into gravity filters, centrifugal filters, etc. according to their principles. Among them, the gravity filter uses the solid-liquid mixture to be discharged through the filter medium under the action of its own gravity. The common normal pressure filtration method is to use an ordinary glass funnel as a filter, use a filter screen as a filter medium, and filter the mixture to obtain the filtrate and Solid particles remaining on the filter. A separatory funnel is a separatory device commonly used in laboratories to separate two immiscible liquids. . [0003] In many experiments, two steps of filtration and liquid separation are included. For example, when a solid-liquid mixture containing water, oil and rock powder needs to be separated in a t...

AI Technical Summary

Problems solved by technology

In this way, filtration and liquid separation usually need to be carried out in filters and separatory funnels, and the operation is complicated and time-consuming.

At the same time, the mixture will remain on the inner wall of the filter, and the mixed liquor will remain on the inner wall of the separatory funnel. Although the residue on a single device may be less, the accumulation of residue from the two devices will still be greater. affect test results
