Description

Sensitive Liquid Filters

technical field

The utility model relates to the technical field of preparation of special instruments for chemical experiments, in particular to a novel filter device used for filtering sensitive liquids under the protection of inert gas or sensitive liquids involved in the reaction process.

Background technique

In chemical experiments, it is often encountered that some substances are sensitive to air and water vapor. Such substances are stored in an inert atmosphere. At the same time, chemical experiments involving such substances sensitive to air and water vapor are usually carried out in an inert atmosphere. Usually A chemical experiment will involve multi-step chemical reactions, and the previous chemical reaction steps will generate some substances that do not participate in the subsequent chemical reactions, and even residues or raw materials will make the subsequent chemical reactions difficult to occur or the yield will be low; The chemical reaction uses some raw materials that have not been reacted and are not suitable for subsequent reactions. They need to be removed by filtration and separation. If they are not separated, they may affect the subsequent chemical reactions. This is often very troublesome. The usual method is In the deposition method, the reaction solution is settled for a certain period of time, and the supernatant is taken with a syringe or a double needle tip for the next chemical reaction. At this time, several major disadvantages will be faced: loss of reaction raw materials; inaccurate measurement of reaction raw materials; transfer of reaction raw materials The introduction of air and water vapor in the process may even lead to safety accidents such as spontaneous combustion or explosion of the reaction system.

Utility model content

The purpose of this utility model is to make up for the shortcomings of the existing sensitive liquid filtration technology under the protection of inert gas, and provide a new type of sensitive liquid filtration device under the protection of inert gas. It is convenient, quick and effective, and the device will not bring oxygen and water vapor in the air into the reaction system in the process of filtering sensitive liquids.

The utility model is achieved through the following technical solutions:

The utility model provides a sensitive liquid filtering device, which comprises a buffer bottle, a liquid inlet pipe and a liquid outlet pipe. A filter plate, the filter plate separates the buffer bottle into the front buffer chamber and the rear buffer chamber, the middle part of the liquid inlet pipe is provided with a front suction joint, the middle part of the liquid outlet pipe is provided with a rear suction joint, and the middle part of the liquid inlet pipe is provided with a rear suction joint. The mouth of the liquid pipe is provided with a threaded rubber plug.

As a preferred solution, the liquid inlet pipe is connected to the front two-neck bottles through a conduit, the mouth of the two front two-necked bottles is provided with a threaded plug, and two ends of the conduit are respectively provided with a double-pointed needle.

As a preferred solution, the mouth of the liquid outlet pipe is connected with the rear two-necked bottles.

As a preferred solution, the filter plate is a sand core baffle.

As a preferred solution, the front buffer bin and the rear buffer bin are detachably connected.

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

1. The salient features of this utility model are safer and quicker than traditional sensitive liquid filtering devices under the protection of inert gas. The filtering process is completed in an inert atmosphere without contact with oxygen and water vapor in the air. The entire filtering process is within a few minutes. It can be completed, which greatly facilitates the filtration of sensitive liquids under the protection of inert gas;

2. The sensitive liquid filtering device under the protection of inert gas makes full use of gravity, and can determine the speed of filtering liquid by changing the mesh number of the sand core baffle according to the requirements of different filter object particle diameters;
