Description

Separation and collection device for mixtures of insoluble liquids of different densities

technical field

The utility model relates to a separation and collection device for a mixture of insoluble liquids with different densities, in particular to a separation and collection device for separating dichloromethane extract containing water.

Background technique

The dichloromethane used for extraction will dissolve a small amount of paraffin oil after extraction, and the dichloromethane extract containing paraffin oil enters the collection tank. In this process, due to low-temperature condensation, leakage and other reasons, a certain amount of water will be mixed in the extract solution. A certain level of water layer appears, because the density of dichloromethane is higher than that of water, in the storage tank, the water layer is in the upper layer, so the water in the storage tank cannot be easily discharged.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide a separation and collection device for a mixture of insoluble liquids of different densities, which is convenient for separation.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A separation and collection device for a mixture of insoluble liquids of different densities, comprising a collection tank and a float level gauge installed in the collection tank, the liquid in the collection tank is divided into upper and lower layers, and a useful In the liquid inlet connected with the mixture generating device and the overflow port for discharging the upper liquid, the float level gauge has a float, and the density of the float is higher than that of the upper liquid and smaller than that of the lower liquid.

Preferably, the separation and collection device further includes a waste liquid tank, and the waste liquid tank communicates with the overflow port through an overflow pipeline for collecting the upper liquid.

More preferably, at least one overflow valve is arranged on the overflow pipeline.

Further, two overflow valves are arranged on the overflow pipeline.

The utility model adopts the above technical scheme, and has the following advantages compared with the prior art: the insoluble liquid in the upper layer in the storage tank can be discharged or collected very conveniently.

Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly .

Figure 1 shows a separation and collection device for a mixture of insoluble liquids of different densities according to the present invention, specifically a separation and collection device for a dichloromethane extract mixed with water.

As shown in FIG. 1 , the separation and collection device includes a collection tank 1 and a float level gauge 2 arranged in the collection tank 1 . The dichloromethane extract mixed with water in the collection tank 1 is left to stand and then layered according to the density, the water layer 11 is on top, and the dichloromethane layer 12 is on the bottom. A liquid inlet (not shown) and an overflow port 3 are provided on the collection tank 1, wherein the liquid inlet is connected with a mixture generating device (in this embodiment, an extraction device for paraffin oil) to allow dichloromethane to extract The liquid enters the collection tank 1 to be collected, and the overflow port 3 is used to discharge the upper water layer 11 .

The separation and collection device also includes a waste liquid tank 6, which communicates with the overflow port 3 through an overflow pipeline 4 for collecting the upper liquid. At least one overflow valve 5 is arranged on the overflow pipeline 4 . Specifically in this embodiment, two overflow valves 5 are provided on the overflow pipeline 4 to avoid leakage caused by damage to one of the overflow valves 5 . In other embodiments, a pump can also be directly used to draw out the upper layer liquid from the overflow port 3 .

The density of the float 21 of the float liquid level gauge 2 is greater than the upper liquid (water) and less than the lower liquid (methylene chloride). The liquid level, and then draw the height of water layer 11. When the liquid level of the dichloromethane layer 12 in the collection tank 1 reached a certain value x, the height of the water layer 11 was h, and at this moment, the height y of the overflow valve 5 just met the following conditions: x<y<(x+h ), the relief valve 5 can be opened after the above conditions are met. The water is collected in the waste liquid tank 6 from the overflow valve 5 through the overflow pipe, while the dichloromethane is still in the collection tank 1, thereby separating and collecting the two layers of liquid respectively.

The above-mentioned embodiment is only to illustrate the technical concept and characteristics of the present utility model. It is a preferred embodiment, and its purpose is to allow those familiar with this technology to understand the content of the present utility model and implement it accordingly, and it cannot be used to limit it. Protection scope of the present utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
