Problems solved by technology

[0004] Ordinary screw system has short stroke, poor mixing effect, insufficient response, and heavy production load on later equipment
It is only suitable for conveying dry powder, not suitable for conveying slurry. The dust raised during dry powder conveying is very large, the system is easy to be blocked, causing mechanical failure, and the equipment is difficult to operate continuously.
Most of the materials used are common materials for overall processing and manufa

Abstract

The invention discloses a double-support prereactor for hydrogen fluoride. A main shaft consists of a front shaft head, a hollow shaft and a rear shaft head, wherein the front shaft head, the rear shaft head and the hollow shaft are welded into a whole; the front section of the hollow shaft corresponds to a main bearing section, the middle section of the hollow shaft corresponds to a fluorite feeding section and a reaction section, and the rear section of the hollow shaft corresponds to an extension expansion section. A spiral main shaft is made of a 40CrMoNiA thick-wall pipe and a 40CrMoNiA forging piece after welding and quenching and tempering treatment. Spiral components with different materials and shapes are installed on the main shaft to not only improve the corrosion resistance ofdifferent sections of the prereactor, but also solve the welding problem between different alloys and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reactor. Background technique [0002] The hydrogen fluoride pre-reactor is a screw conveying device with mixing control and heating reaction. [0003] The main shaft screw system of the hydrogen fluoride pre-reactor adopts a 5-meter-long hollow cantilever shaft screw-type stirring propeller. Driven by a frequency conversion motor and a reducer, it has the function of combining continuous rotation and axial reciprocation. The equipment is reciprocated and interspersed, with multiple functions such as mixing, kneading, and evenly conveying materials. The stirring motion of the spiral system, the blade on the shaft sleeve stirs the fluorite, prevents the powdery fluorite from settling, and makes the reaction go smoothly. The by-product of the reaction between fluorite and sulfuric acid is gypsum. During the process, a gypsum film will be formed on the surface of fluo...
