Description

A laboratory desktop waste liquid treatment device

technical field

The utility model relates to a waste liquid treatment device, in particular to a laboratory table waste liquid treatment device.

Background technique

In the laboratory, according to different classification standards of waste liquid, it can be divided into organic solution and inorganic solution, acid solution and alkaline solution, etc.; the existing waste liquid treatment is generally collected first, and then transported to a unified place for treatment; That is to say, the waste liquid is collected in the laboratory first. During the collection process, some waste liquid will inevitably volatilize, causing pollution to the laboratory, and cannot be effectively and timely treated.

Utility model content

The purpose of the utility model is to consider the above problems and provide a laboratory desktop waste liquid treatment device that can process waste liquid in time.

In order to achieve the above purpose, the technical solution of the utility model is: a laboratory desktop waste liquid treatment device, including a liquid collection bottle and a filter bottle, the liquid collection bottle and the filter bottle are connected by a rubber tube, and the filter bottle is set There are a filter layer, an activated carbon layer, and a chromatographic silica gel layer. The outlet of the filter bottle is provided with a suction pump; layer; a chromatographic silica gel layer is provided above the activated carbon layer. The liquid collection bottle is used to collect waste liquid during the test. The waste liquid collected in the liquid collection bottle flows into the filter bottle through the rubber hose, and the waste liquid is sucked from the bottom of the filter bottle to the outlet by the suction pump at the outlet of the filter bottle. At the place, pass through the filter layer, activated carbon layer, and chromatographic silica gel layer in turn; the filter layer can filter out solid particles such as waste residue in the waste liquid; the activated carbon layer can remove the color in the waste liquid; the chromatographic silica gel layer can absorb residual Substances in waste streams. The filter layer is set at 1/4 height of the bottom of the filter bottle, that is to say, there is enough space at the bottom of the filter bottle to buffer the waste liquid and retain the waste residue.

As an improvement to the above technical solution, the mesh size of the chromatographic silica gel layer is 320-390 mesh.

As an improvement to the above technical solution, both the liquid collection bottle and the filter bottle are made of tempered glass. Due to the characteristics of the waste liquid, the liquid collection bottle and the filter bottle are made of tempered glass, which can resist acid, alkali and high temperature.

As an improvement to the above-mentioned technical scheme, the thickness of the activated carbon layer is 1/5 of the height of the filter bottle. In order to ensure the filtering effect of the activated carbon layer, there are certain requirements for the thickness of the activated carbon layer. The activated carbon layer is too thin for insufficient filtration. The activated carbon layer is too thick to affect the filtration efficiency.

As an improvement to the above technical solution, the rubber hose is an acid and alkali resistant, high temperature silicone rubber hose.

Compared with the prior art, the utility model has the following effects:

1. The waste liquid treatment device can conduct preliminary treatment of the waste liquid in time, reducing the pollution of the waste liquid to the laboratory;

2. The waste liquid inlet and outlet of the waste liquid treatment device are respectively set at the bottom and upper part of the filter bottle, which prolongs the exchange time between the waste liquid and the filter layer, activated carbon layer, and chromatographic silica gel layer, and the waste liquid is purified more thoroughly;

3. The structure of the waste liquid treatment device is simplified, which is conducive to the development of miniaturization of products and does not occupy laboratory space.
