Slurry extraction equipment with pre-filtering function, and using method thereof

Abstract

The invention relates to the technical field of extraction equipment, particularly to slurry extraction equipment with pre-filtering function, and a using method thereof. The equipment comprises a machine body, a dustproof device, a cleaning device and a filtering device, wherein the top end of the left end surface of the machine body communicates with a light-phase liquid inlet pipe, the top endof the right end surface of the machine body communicates with a heavy-phase liquid inlet pipe, the bottom end of the left end surface of the machine body is communicated with a heavy-phase liquid outlet pipe, and the bottom end of the right end surface of the machine body communicates with a light phase liquid outlet pipe. In the present invention, the arrangement of a filter screen box is matched with the fixed connection of the filter screen box and a sliding frame, the sliding connection of the sliding frame and a positioning frame and the sliding connection of a rotating rod and the sliding frame; when the equipment is used, extraction can achieve pre-filtration, and the filtering effect is good, so that the concentration of an extracted solution is guaranteed; and the filter screen box can be automatically replaced under the control of a controller, and the replacement efficiency is high, so that the extraction efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of extraction equipment, in particular to an extraction equipment for slurry with a pre-filtering function and a use method thereof. Background technique [0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is also called extraction. It is a mass transfer separation process that uses a liquid extractant to treat a two-component or multi-component solution that is immiscible with it to achieve component separation. A widely used unit operation, the common extraction machines include ultrasonic extraction machine, microwave extraction machine, centrifugal extraction machine, the extraction machine uses the difference in solubility or partition coefficient of the compound in two immiscible solvents to make the compound from one solvent to another solvent. [0003] In the field of extraction equipment, some extraction equipment currently in use cannot filter the extracted solution ...

AI Technical Summary

Problems solved by technology

[0003] In the field of extraction equipment, some extraction equipment currently in use cannot filter the extracted solution in advance, which will affect the concentration of the extracted solution. Although there are some extraction equipment that can be filtered, the filtering effect is poor. Moreover, it is particularly time-consuming when replacing and cleaning the filter mechanism, which greatly reduces the extraction efficiency. In addition, the automatic cleaning of the filter mechanism and the automatic collection of foreign matter cannot be realized, which greatly increases the labor intensity of the staff. When not in use, the connecting pipelines cannot be well protected, so that dust and foreign matter will enter the extraction equipment, affecting the normal use of the device. Although there are some protective measures, the protective mechanism is inconvenient to use and easy to lose
