Sampling device of mixing and clarifying tank

Abstract

The invention relates to a sampling device of a mixing and clarifying tank. The device comprises a plurality of sampling tubes (5) connected with the mixing and clarifying tank, a sampling box (1) connected with the plurality of sampling tubes (5), a sampling box pedestal (14) and a vacuum buffer tank (8); the sampling box (1) is arranged in the sampling box pedestal (14), and the vacuum buffer tank (8) is connected with the inner cavity of the sampling box pedestal (14); and the top board (1-1) of the sampling box (1) is provided with a plurality of holes, a position corresponding to each of the holes is connected with a vertical downward hard sleeve tube (2), all the sampling tubes (5) traverse through all hard sleeve tubes (2) and stretch to the bottleneck of a sampling bottle arranged in the sampling box pedestal (14), and the outer walls of the sampling tubes (5) are in sealed contact with the inner walls of the hard sleeve tubes (2). The sampling device has the advantages of compact structure, operating convenience, easy maintenance and strong durability.

Description

technical field [0001] The invention belongs to the technical field of mixing and settling tanks, in particular to a sampling device for mixing and settling tanks. Background technique [0002] In the chemical production or experiment where the mixing and settling tank is used as the extractor, it is often necessary to extract the liquid in the tanks of each level of the mixing and settling tank separately. Manipulators operate it from a distance. In the early stage, the inventor developed a sampling device for various levels of miniature mixing and clarification tanks used in hot chamber experiments. Its main structure includes a sampling box and a sampling box base. The base is made of plexiglass, and a glass sampling bottle is placed in the base of the sampling box, and a flexible thin tube is inserted into each clarification chamber of the mixing and clarifying tank, so that the other end of the flexible thin tube penetrates the cover of the sampling box, and the mouth ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned sampling method at all levels of the mixing and settling tank has certain limitations: 1) The material of the sampling box cover and the bottom box is bonded plexiglass, and the sealing is not good, so that it is relatively difficult to take samples by the manipulator, and the durability is not good at the same time ; 2) The flexible tube passes through the box cover and is prone to bending, which causes the sample to fail to flow into the corresponding sample bottle or even enter other sample bottles during sampling, causing sample contamination; Mixing and settling tank, each mixing and settling tank sampling box cover is equipped with a bottom box, and the equipment should be simplified in the radiochemical experiment; 4) In the hot room with strong radioactivity, when personnel cannot enter, the movement and maintenance of the equipment are difficult. can not complete
