Mixing shaft lower positioner with small blade

Abstract

The invention provides a mixing shaft lower positioner with a small blade and the mixing shaft lower positioner is used in the mixing and reaction system of a chemical reaction tank. As the volume of the mixing shaft lower positioner is large and the structure takes up much space, a large regional dead angle exists at the lower end of the mixing shaft in the reaction tank, the blade can not enter the region for mixing and a great number of chemical materials can not react completely owning to the existence of the region. In order to overcome the disadvantage, the small blade is arranged in the mixing shaft lower positioner, thus two mixing spaces are formed in the reaction tank and the completeness of reaction of the chemical materials is greatly increased.

Description

Technical field: [0001] The invention relates to a lower positioner for a stirring shaft with small blades, which is used in a stirring reaction system of a chemical reaction kettle. Background technique: [0002] In the chemical industry, the stirring system of the reactor is an extremely important system in the structure of the entire reactor. Some of the stirring systems of the reactor are due to the high viscosity of the chemical materials to be processed, or the complex structure of the stirring system and the heavy weight of the stirring system. It is easy to shake when the load is too large. At this time, it is necessary to install the lower locator of the stirring shaft at the lower end of the stirring shaft; however, because the lower locator of the stirring shaft is large in size and takes up a lot of space in the structure, a large piece of stirring system appears at the lower end of the stirring shaft in the reactor. The paddles cannot enter the dead corner of th...

At this time, it is necessary to install the lower locator of the stirring shaft at the lower end of the stirring shaft; however, because the lower locator of the stirring shaft is large in size and takes up a lot of space in the structure, a large piece of stirring system appears at the lower end of the stirring shaft in the reactor. The blades cannot enter the dead corner of the stirring area. Due to the existence of this area, a considerable part of the chemical materials cannot be completely reacted. This is especially true when dealing with high-viscosity chemical materials. It is extremely unfavorable for many chemical reactions
