Reverse back stopping mechanism and rotary reaction equipment for external-free driving propeller

Abstract

The invention discloses a reverse back stopping mechanism and rotary reaction equipment for an external-free driving propeller. The reverse back stopping mechanism comprises at least one limiting connecting rod, a positioning disc, a bearing and a rocker connecting rod, wherein the positioning disc is positioned in the center of the limiting connecting rod and is fixedly connected with the limiting connecting rod; the bearing is embedded to the center of the positioning disc; one end of the rocker connecting rod is arranged inside the bearing in a penetration manner; the other end of the rocker connecting rod is propped against a side end surface of the external-free driving propeller, and forms point contact with the side end surface of the external-free driving propeller. The rotary reaction equipment comprises a reactor cylinder, the external-free driving propeller and the reverse back stopping mechanism. By adopting the reverse back stopping mechanism and the rotary reaction equipment, precise coaxial movement of the external-free driving propeller and the cylinder of the rotary reaction equipment is achieved, so that axial limiting, axial parallel, equal linear velocity and the like of the external-free driving propeller on an inner wall surface of the reactor cylinder can be maintained, and a stable operation state can be achieved.

Description

technical field [0001] The invention relates to a rotary reaction device, in particular to a reverse anti-retraction mechanism and a rotary reaction device for no externally driven helical roller. Background technique [0002] In the prior art, the rotary reactors used roughly include two types: [0003] One is the traditional horizontal continuous rotary reactor, the spirals in the horizontal continuous rotary reactor are all fixed on the inner wall of the reactor or driven by external power, so that the materials are pushed by the friction of the spiral blades Movement to complete quantitative continuous production. [0004] The other is the traditional unpowered internal helical roller rotary reactor. Under the reaction force of the reaction material, the unpowered internal helical roller rotary reactor causes collision and friction between the inner helical roller shaft and the blade and the reactor cylinder, causing the spiral The axial and angular phase displacement ...
