It should be understood that the implementation of the utility model is not limited to the following embodiments, and any form of modification and / or change made to the utility model will fall within the scope of protection of the utility model.

The methods in the following examples are conventional methods in the art unless otherwise specified. The components or equipment in the following examples are general standard components or components known to those skilled in the art unless otherwise specified.

[0027] The embodiments of the utility model will be described in detail below in conjunction with the drawings. In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments of the utility model. However, one or more embodiments can be implemented by those skilled in the art without these specific details.

[0028] As shown in Figure 1 and Figure 2 , the device comprises a liquid separation tank 1, a limiting cylinder 2, a cover body 3 and a suspension member 4. Among them, the liquid separation tank 1 is mainly used for containing and separating liquid, and the outer upper end is detachably installed with the cover body 3, the cover body 3 below is provided with the suspension member 4, and the two are detachably connected, so that the user can replace the suitable suspension member 4 according to the liquid system with different densities.

[0029] As shown in Figure 3 and Figure 4As shown in the drawings, the suspending member 4 comprises a connecting portion 401, a wire body 402 and a suspending ball 403. The connecting portion 401 is used to realize detachable connection of the suspending member 4 and the cover body 3; the wire body 402 connects the suspending ball 403 and the connecting portion 401, thereby facilitating the user to extract the suspending ball 403 from the liquid separation tank 1; and the suspending ball 403 is used to position and identify the interface position of the two kinds of liquids. The suspending ball 403 is provided with a plurality of through holes 11 on the surface, which helps liquid circulation and prevents the suspending ball 403 from blocking the lower liquid discharge pipeline 7.

[0030] The liquid separation tank 1 is internally provided with a limiting cylinder 2, which is composed of a plurality of rod bodies 201 arranged at equal intervals in the circumferential direction and fixedly connected with the liquid separation tank 1, and together forms a guide channel for the suspending member 4 to move up and down, thereby effectively preventing the suspending member 4 from deviating or being stuck.

[0031] In addition, the suspending ball 403 is internally provided with a fixedly connected magnet 5, and the liquid separation tank 1 is provided with a dry reed tube 6 at the bottom. When the suspending ball 403 descends with the lower liquid surface to the bottom of the liquid separation tank 1, the magnet 5 approaches the dry reed tube 6 and triggers the dry reed tube 6 to be conductive. The dry reed tube 6 is electrically connected with an electric three-way valve 9 arranged at the bottom of the liquid separation tank 1, and the three-way valve is used to control the switching of the liquid discharge path. Specifically, the liquid separation tank 1 is provided with a liquid discharge pipeline and two liquid separation pipelines 8 at the bottom. One end of the liquid discharge pipeline is communicated with the liquid separation tank 1, and the other end is communicated with the two liquid separation pipelines 8 of the upper and lower liquids through the electric three-way valve 9, respectively. When the dry reed tube 6 receives the signal of the magnet 5, the three-way valve automatically switches the liquid discharge direction according to the control signal, thereby realizing the sequential separation and discharge of the upper and lower liquids.

[0032] In order to ensure that the liquid can be fully and stably layered in the tank body, the upper part of the liquid separation tank 1 is further provided with an electromagnetic valve 10 communicated with the tank body, which is used to control the opening and closing state of the liquid separation tank 1 during the liquid separation process, and guarantee the smooth progress of the subsequent liquid discharge process.

[0033] The implementation principle of the novel liquid-liquid separator for extraction is as follows:

[0034] Based on the characteristics of the natural layering of liquids with different densities in the static state. By setting a replaceable suspending member 4 and selecting a suspending ball 403 with appropriate density according to the density difference of the liquid system, the suspending ball 403 is stably suspended at the interface of the two liquids, thereby realizing automatic identification of the liquid-liquid interface.

[0035] The inside of the liquid separation tank 1 is provided with a limiting cylinder 2, which is composed of a plurality of rod bodies 201 arranged at equal intervals, forming a guide channel for guiding the up-down movement of the floating member 4. After the cover body 3 is installed, the floating member 4 naturally vertically extends into the limiting cylinder 2 and floats up and down with the change of the liquid interface. When the liquid surface drops to a certain position, the magnet 5 contained in the floating member 4 approaches the dry reed tube 6 installed at the bottom of the liquid separation tank 1, triggering the conduction of the dry reed tube 6, and then sending a control signal.

[0036] The control signal is used to drive the electric three-way valve 9 to switch the liquid discharge path, so that the upper and lower liquids in the liquid separation tank 1 can be discharged from the corresponding liquid separation pipelines 8 in sequence and accurately, avoiding mixed pollution. The surface of the floating ball 403 is provided with a through hole 11 structure, which helps the normal flow of liquid and prevents the ball from blocking the liquid discharge.

[0037] The principle and implementation mode of the present application are described by using specific examples in the present application. The above examples are only used to help understand the method and core idea of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
