technical field

The utility model relates to a two-way stirring type reaction kettle.

Background technique

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. Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors, reaction pots, decomposition pots , polymerization kettle, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.

In the actual production and application of the reaction kettle, the requirements for the stirring impeller are comprehensive and multifaceted. For example, the propeller type agitator mainly causes the axial liquid flow and produces a large circulation volume, but the difference in the density of various reaction materials When it is larger, the mixing effect of the traditional propeller agitator is not good, which affects the reaction speed.

It is characterized in that: the other end of the stirring shaft is connected to the reducer through a steering controller, and the stirring shaft includes an inner shaft and the outer shaft, the inner shaft fixes the output shaft of the reducer, the inner shaft and the outer shaft are fixed with a propeller-type stirring paddle, the inner shaft is installed in the outer shaft, and the steering controller includes a connecting sleeve, a planetary gear, Planetary support, planetary bearing, first one-way bearing, internal gear and internal ring gear, the connecting sleeve is fixed on the upper end of the outer shaft, the internal ring gear is fixed inside the connecting sleeve, and the planetary support is installed on the inner shaft through the rotation of the planetary bearing. The inner gear is rotatably installed on the inner shaft through the first one-way bearing, and the planetary gear is rotatably installed on the planet carrier, and the planetary gear meshes with the inner gear and the ring gear. The stirring working mode of the two-way stirring reactor of the utility model is as follows: the motor rotates forward, drives the reducer to rotate, and the reducer drives the inner shaft to rotate, so that the propeller type stirring paddle on the inner shaft rotates forward, so that the reaction raw materials at the bottom are upward flow, the inner shaft rotates forward, and the first one-way bearing is in the locked direction at this time, so the inner shaft drives the inner ring gear through the first one-way bearing, thereby driving the inner ring gear through the planetary gear, thereby driving the outer shaft to rotate in the reverse direction , so that the propeller-type stirring paddle on the outer shaft rotates in reverse, so that the reaction raw materials at the top flow down, so that the reaction raw materials of different layers can meet in the middle, which accelerates the mixing speed, the mixing effect is better, and the reaction speed is improved. After the motor rotates in reverse, the propeller-type stirring paddle on the inner shaft rotates in reverse, so that the reaction raw materials flow downward, and the reverse rotation of the inner shaft, at this time, the first one-way bearing is in the direction of free rotation, so the propeller The stirring paddle does not rotate.

As a preference, a fixed outer ring is fixed on the upper end of the connection jacket, a fixed inner ring is fixed on the inner wall of the upper end of the tank body, and an upper deep groove ball bearing and a lower deep groove ball bearing are arranged between the upper inner wall of the tank body and the outer wall of the connection jacket. The jacket is rotatably mounted on the upper end of the tank through the upper deep groove ball bearing and the lower deep groove ball bearing, and the inner ring of the upper deep groove ball bearing is against the lower end of the fixed outer ring, and the outer ring of the lower deep groove ball bearing is against the lower end of the fixed outer ring. Fix the upper end of the inner ring.

Preferably, the upper end of the connecting sleeve is mounted on the inner shaft through a second one-way bearing, and the locking directions of the first one-way bearing and the second one-way bearing are oppositely set. With this structure, when the motor reverses, the inner shaft and the outer shaft rotate at the same time, thereby realizing the effect of the double-propeller agitating blades rotating in the same direction.

Preferably, the second one-way bearing is located above the first one-way bearing.

Compared with the prior art, the utility model has the following advantages and effects: the utility model bidirectional stirring type reactor can make the inner shaft and the outer shaft turn in the opposite direction when the motor is rotating forward, so the two propeller type stirring paddles Turn to the opposite, so that the reaction raw materials of different layers can meet in the middle, accelerate the mixing speed, the mixing effect is more effective, and the reaction speed is improved.
