A leak-proof high-viscosity fluid mixing reactor

Abstract

The invention belongs to the technical field of chemical mechanical equipment and discloses a leakage-preventing high-viscosity fluid mixing reaction kettle. An oil leakage preventing structure is arranged on the reaction kettle, and the reaction kettle is simple in structure, reliable in work and capable of meeting the usage requirements of oil leakage forbidding. An air guide device is arranged inside the reaction kettle, can ensure sufficient air circulation volume and can also ensure the operating strength of a stirring shaft. A cyclic cooling device is arranged in a magnetic driving device of the reaction kettle, it can be ensured that the driving device can operate smoothly and stably, and impurities can be effectively prevented from entering the device, and the reaction kettle is easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of chemical machinery equipment, in particular to the field of high-performance fluid mixing and separation machinery manufacturing, and relates to a leak-proof high-viscosity fluid mixing reactor. Background technique [0002] The reaction kettle or stirring tank is a common equipment in chemical production. The stirring device of the reaction kettle or stirring tank is a device for forced convection and uniform mixing of solid, liquid or gas medium. The stirring device adopts mechanical seal or magnetic seal. Once the shaft seal leaks, the oil in the stirring device will enter the reaction kettle or stirring tank system, which will affect the product quality. For example, in reaction kettles with high-viscosity materials (such as polyphenylene sulfide, polyether ether ketone, polysulfone, etc.), oil leakage at the seal of the stirring device often occurs, resulting in product quality degradation or product...

AI Technical Summary

Problems solved by technology

But the above-mentioned oil leakage prevention structure has the following disadvantages: 1. Poor versatility, the shape and size of the cover plate and the movable cover plate are suitable for the mouth size of the reaction kettle or the mixing tank used together

This design is not suitable for non-open reactors, otherwise it will change the structure of the original reactor and affect the sealing of the reactor, etc.

2. The structure is relatively complex and consumes a lot of materials, so it is difficult to modify the existing reactor or stirring tank

The existing cooling method mostly adopts the method of adding cooling coils on the rotating shaft, which is inconvenient to maintain during use, and the cooling is uneven and the effect is poor
