Automatic settling kettle for extraction separation and control method

Abstract

The invention discloses an automatic settling kettle for extraction separation and a control method. The automatic settling kettle comprises a kettle body, a kettle cover covering an opening of the kettle body, a feeding assembly, a stirring assembly and a pressure material transferring assembly. An electromagnetic liquid level meter connected with a control system is fixed on the kettle cover andis used for detecting the heights of a gas-liquid interface and a solid-liquid interface in the kettle body. The pressure material transferring assembly comprises a pressure material transferring pipe, a telescopic corrugated pipe, a buoy, a rotational flow preventer and a supporting plate, one opening of the pressure material transferring pipe extends into the kettle body and is fixedly connected with one end of the telescopic corrugated pipe, the other end of the telescopic corrugated pipe is connected with the rotational flow preventer, the buoy is fixed to the rotational flow preventer, the supporting plate is fixed to the lower end of the rotational flow preventer, and the buoy is slidably connected with a guide rail inside the kettle body through a pulley. A conductivity meter connected with the control system is fixed at the part, positioned outside the kettle body, of the pressure material transferring pipe. The device is simple in structure and convenient to operate, automatic continuous operation of the extraction separation process can be achieved, solvent consumption is reduced, and the extraction separation efficiency is improved.

Description

technical field [0001] The invention relates to a reaction kettle, in particular to an automatic settling kettle for extraction and separation and a control method. Background technique [0002] In the process of chemical production, it is often necessary to perform extraction and solid-liquid separation operations on the mixture. Usually, a solvent is added to the reaction kettle for extraction, and then the purpose of solid-liquid separation of the medium in the reaction kettle is achieved by means of pressure filtration. This method is easy to operate, and the equipment Simple, but there are problems such as low degree of automation, long operation process, large amount of subsequent solid material washing solvent, low efficiency, and non-continuous operation. Contents of the invention [0003] The object of the present invention is to provide an automatic settling tank and control method for extraction and separation, which has a simple structure and convenient operati...
