Convenient-to-clean reaction kettle with valve pipe for chemical production

Abstract

The invention discloses a convenient-to-clean reaction kettle with a valve pipe for chemical production. The reaction kettle comprises a cleaning device, wherein a jacket (8) is arranged outside a kettle body (6); a feeding opening is formed in the top of the kettle body (6); a discharging pipe (19) is arranged at the bottom of the kettle body (6); a feeding opening (3) is formed in the top of thekettle body; a stirring shaft (15) is arranged in the kettle body; a sealing sleeve device (16) is sleeved on the upper part of the stirring shaft (15); the stirring shaft (15) is of a tubular structure, and is provided with an inner cavity (150); the bottom end of the stirring shaft (15) is provided with a bearing seat (190); the sealing sleeve device comprises an outer cover (51); the outer cover (51) is sleeved on the stirring shaft (15); the upper and lower ends of the outer cover are fixedly provided with sealing bearing assemblies (18). The cleaning device has the advantages that the two sealing bearing assemblies are arranged at the upper and lower ends inside the outer cover, a water inlet hole is formed in the lateral part of the outer cover, so that when the stirring shaft rotates in the outer cover; the outer cover is fixed; during chemical reaction, materials, chemicals and the like can pass through an acceleration reaction hole, a pressure difference and a water flow difference are formed, so that the contact of reactants can be more uniform and thorough, so that the chemical reaction speed is higher.

Description

technical field [0001] The invention belongs to the related technical field of chemical equipment, and in particular relates to a reaction kettle with a valve pipe for easy cleaning in chemical production. Background technique [0002] The broad understanding of the reaction kettle is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. [0003] The prior art has the following problems: 1. The stirring rod of the existing reactor has a single function, and cannot provide the functions of spraying liquid or air, accelerating or decelerating the reaction. [0004] After the existing reactor is used, it is simply cleaned by injecting water into the feed port, or by shaking, which leads to the fact that it can only clean the dirt with weak adhesion, which is relatively stubborn. 2. The environment in the e...
