Reaction kettle bottom agitation system

Abstract

The invention discloses a stirring system at the bottom of a reaction kettle, which can be widely applied to the processes of shearing, emulsification and homogenizing in media of petroleum trade, chemical industry, pharmaceuticals industry, food service industry, etc. The reaction kettle is internally provided with an air guide sleeve the upper end and the lower end of which are both open. The lower part of a stirring device in the air guide sleeve is provided with a transmission device which is fixed at the bottom of the reaction kettle. Cartridge and combined mechanical seals are arranged between the bottoms of the transmission device and the reaction kettle, and the transmission device is connected with a power output shaft of a speed reducer while a power input shaft of the speed reducer is connected with a motor. With the respect to the problem of the over-length of stirring shafts in the general jacking structure adopted, the stirring system of the invention can greatly shorten the length of the stirring shaft and ensure the stable operation and that a rotating shaft bears small subsidiary stress, thus providing comparatively favorable application environment for sealing.

Description

technical field [0001] The invention can be widely used in the processes of shearing, emulsification and homogenization of media in industries such as petroleum, chemical industry, medicine and food. Background technique [0002] With the development of modern industry, chemical equipment is gradually becoming large-scale, and the reaction kettle is also showing a trend of large-scale. For large-scale reactors, most of them are installed vertically. In the prior art, the top-entry structure is mostly used. In this top-entry structure, the stirring shaft needs to extend from the top of the kettle to the bottom of the kettle, so there is a stirring shaft The problem of too long, and too long agitator shaft will cause many problems. For example, in order to ensure the torsional strength of the agitator shaft, the shaft diameter needs to be thickened. If the shaft diameter is thickened, the support must be strengthened, which will increase the weight and processing costs. Cont...

Problems solved by technology

For large-scale reactors, most of them adopt the vertical installation method. In the prior art, the top-entry structure is mostly used. In this top-entry structure, the stirring shaft needs to extend from the top of the kettle to the bottom of the kettle, so there is a stirring shaft The problem of too long, and too long agitator shaft will cause many problems, such as in order to ensure the torsional strength of the agitator shaft, it is necessary to increase the diameter of the shaft, and the thicker the diameter of the shaft, the support must be strengthened, which will increase the weight, processing costs, etc.
