Description
Technical Field
The utility model relates to a solvent bottle mouth purifying and filtering device, and belongs to the technical field of bottle mouth filtering pieces.
Background
The solvent is usually stored in a solvent bottle, and when needed, the solvent is extracted and conveyed to a corresponding instrument for use. For precision instruments using solvents, the solvents are filtered by pouring them out, and the impurities are filtered before use. Thus, the device has a protective effect. For example, when using chromatographic solvents in a chromatograph, the chromatographic solvents need to be decanted for filtration and then used in the chromatograph. Thus, the complicated working procedure and the low working efficiency are caused.
Disclosure of Invention
The utility model aims to provide a solvent bottle mouth purifying and filtering device which can realize real-time filtering in the process of extracting a solvent.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
a purifying and filtering device for a solvent bottle mouth comprises a container cover, an air inlet valve and a filter; the air inlet valve is arranged on the container cover, so that air enters the inner side of the bottle in one direction; a liquid outlet port of a filter is also embedded and arranged on the container cover; the inner side of the liquid outlet port is connected with a filter.
The technical scheme of the utility model is further improved as follows: the air inlet valve is an annular air inlet valve which is embedded in the container cover; the liquid outlet port is inlaid and installed in the middle of the annular air inlet valve.
The technical scheme of the utility model is further improved as follows: one end of the filter is communicated with the liquid outlet port through a connecting pipe, and the other end of the filter is connected with a one-way valve.
The technical scheme of the utility model is further improved as follows: the purification and filtration device is arranged at the container mouth of the chromatographic solvent.
By adopting the technical scheme, the utility model has the following technical effects:
the annular air inlet valve and the liquid outlet port are arranged on the container cover, the liquid outlet port is communicated with the filter, and the annular air inlet valve is arranged to enable air to enter in one direction to keep air pressure balance when solvent is extracted; meanwhile, the filter can realize real-time filtration in the process of extracting the solvent, so that trouble and time are saved.
The purification and filtration device of the present utility model is particularly suitable for being installed at the container mouth of a chromatographic solvent, and when the chromatographic solvent is used, filtration is simultaneously achieved while being drawn out through the container lid. The staff does not need to additionally carry out chromatographic solvent filtration work.
The utility model has reasonable structure arrangement, is simple and feasible, and can improve the working efficiency.

FIG. 1 is a perspective view of the present utility model;
wherein, 1, container lid, 2, admission valve, 3, filter, 4, liquid outlet port, 5, check valve.
Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be configured and operated in the specific direction, and thus should not be construed as limiting the present utility model.
The utility model relates to a solvent bottle mouth purifying and filtering device which is arranged at a solvent bottle mouth and can filter solvent discharged from the solvent bottle.
As shown in fig. 1, the device mainly comprises a container cover 1, and an air inlet valve 2 and a filter 3. Wherein, air inlet valve 2 inlay and set up on container lid 1, air inlet valve 2 can make the air unidirectional access bottle inboard, keeps the air pressure balance in the bottle, guarantees that the solvent can be smoothly extracted. A liquid outlet port 4 of the filter 3 is also embedded on the container cover 1, and the liquid outlet port 4 connects the liquid delivery pipe with the filter 3. The liquid outlet 4 is connected to the outside of the container cover 1 via a liquid pipe, and is connected to the inside of the container cover 1 via a filter 3. The filter 3 is a component for filtering the solvent.
In a specific implementation of the present utility model, the air inlet valve 2 is provided as an annular air inlet valve, and the annular air inlet valve is embedded in the container cover 1. The annular inlet valve is concentric with the container cover. Then, the liquid outlet port 4 is fitted in the middle of the annular intake valve.
Further, the utility model may also be provided with a non-return valve 5 inside the filter 3. That is, one end of the filter 3 is communicated with the liquid outlet 4 through a connecting pipe, the other end of the filter is connected with a one-way valve 5, and the one-way valve 5 is arranged to ensure that the solvent can only flow out through the filter 3 without flowing back, thereby ensuring safety.
The filter of the utility model can be disassembled for cleaning and replaced.
The purification and filtration device can be installed at the container mouth of the chromatographic solvent, and when the chromatographic solvent is used, the purification and filtration device can realize filtration when the chromatographic solvent is extracted outwards through the container cover. The additional filtering process is omitted, and the use efficiency is improved.
According to the utility model, the annular air inlet valve and the liquid outlet port are arranged on the container cover, and then the liquid outlet port is communicated with the filter, so that the real-time filtration during solvent extraction is realized, and the problems, time and labor are saved.
