A kind of extraction and separation equipment with siphon structure

Abstract

The invention provides extraction and separation equipment with a siphon structure, and belongs to the field of extraction equipment. The equipment comprises an extraction main body, a siphon, a control device and a scanning device; a liquid outlet pipe communicating with the interior of the extraction main body is arranged at the bottom of the extraction main body; a liquid valve is arranged in the liquid outlet pipe; a scale line is arranged on the side wall of the extraction main body; the side wall of the part where the scale line is located is made of a transparent material; the siphon isof a U-shaped structure; one end of the siphon extends into the extraction main body from the top of the extraction main body, and is inserted into a liquid in the extraction main body; the other endof the siphon is located on the outer side of the extraction main body, and the port of the end locating on the outer side of the extraction main body is located below the port of the end extending into the extraction main body; the siphon is arranged on a sliding driving device; the control device is electrically connected with the sliding driving device and the scanning device; the scanning part of the scanning device directly faces the part where the scale line of the extraction main body is located; and the scanning device is in sliding connection with the extraction main body. Accordingto the invention, various layered liquids can be automatically obtained, and the precision is high.

Description

technical field [0001] The invention relates to the field of extraction equipment, in particular to an extraction and separation equipment with a siphon structure. Background technique [0002] Solution extraction is a method of transferring a solvent substance from one solvent to another by using the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents. It is widely used in Chemical, metallurgical, food and other industries. Among them, the equipment used for extraction is an extraction and separation device. When the existing extraction and separation devices obtain the extraction layered liquid, they usually use the liquid pipe and liquid valve installed at the bottom of the extraction and separation device to separate and obtain the upper layer liquid. With the outflow of the lower layer liquid, it will fall and be confused with the lower layer liquid attached to the inner wall of the extraction and separ...

Problems solved by technology

Among them, the equipment used for extraction is an extraction and separation device. When the existing extraction and separation devices obtain the extraction layered liquid, they usually use the liquid pipe and liquid valve installed at the bottom of the extraction and separation device to separate and obtain the upper layer liquid. With the outflow of the lower layer liquid, it will fall and be confused with the lower layer liquid attached to the inner wall of the extraction and separation device. At the same time, if you are not careful, the mixed layer will flow out with the lower layer liquid, thereby affecting the purity of the lower layer liquid; It is necessary to manually check and operate. The accuracy of the layered liquid obtained by this method is not high. If you do not pay attention, the two layered liquids will be taken out together. Therefore, it is difficult to obtain the layered liquid by manual operation, and the accuracy not tall
