Adsorption stirring kettle

Abstract

The invention relates to the field of stirring kettles and in particular relates to an adsorption stirring kettle. The adsorption stirring kettle comprises a tank body, a drive motor, a transmission shaft, a resin feeding pipe, an adsorption liquid feeding pipe and stirring blades, wherein the drive motor is mounted at the upper end of the tank body; the transmission shaft is connected to the lower end of the drive motor; a stirring shaft is connected to the lower end of the transmission shaft; the stirring shaft runs through the tank body and extends into the tank body; the stirring blades are mounted in the middle and at the lower end of the stirring shaft in the tank body respectively; the resin feeding pipe and the adsorption liquid feeding pipe are mounted on one side of the upper end of the tank body; a manhole is formed in the other side of the upper end of the tank body; the manhole is covered with a manhole cover; an outlet valve is mounted at the lower end of the tank body; a spiral guide vane is mounted on the inner wall of the tank body. The adsorption stirring kettle has the advantages that the design is simple and skillful, the production cost is low, and the working efficiency is high; due to the design of the spiral guide vane on the inner wall of the tank body, a solution can float up and down within a large range during stirring, well mixed reaction is realized, the effect is remarkably improved, and the mixing time is shortened; the stirring blades are firm in design structure and convenient to mount and maintain; due to the design of reinforcement ribs, the service life of the kettle is prolonged.

Description

technical field [0001] The invention relates to the field of stirred tanks, in particular to an adsorption stirred tank. Background technique [0002] The stirred tank is used for stirring and mixing chemical materials. It mainly includes a tank body and a stirring shaft extending into the tank body. The stirring shaft is driven by a motor to achieve stirring. At present, the stirring effect of ordinary stirring tanks is not good, and it takes a long time to stir to meet the requirements, and the efficiency is low. Some high-efficiency stirring tanks have high design and production costs, and the structure is relatively complicated. [0003] The resin adsorption step is the least efficient step in the whole heparin production process, and the average adsorption rate is only about 80%. The resin adsorption rate directly determines the yield of heparin. Generally, the volume of the adsorption stirring tank is relatively large (up to hundreds of tons), and it is solid-liquid s...

AI Technical Summary

Problems solved by technology

Generally, the volume of the adsorption stirring tank is relatively large (up to hundreds of tons), and it is solid-liquid stirring, and the viscosity is relatively large. The ordinary stirring tank can easily make the resin and the adsorption liquid in a relatively static state, and the adsorption efficiency is low; on the tank wall Set the baffle, which often damages the resin and affects the service life of the resin; due to the large volume, eccentric stirring also has a certain macroscopic instability
