Energy-saving mechanical stirring device

By installing flow stabilizing components and guiding slopes on the inner wall of the reactor, the circumferential tangential motion of the fluid is disrupted, forcing the fluid to become a composite flow of axial and radial directions. This eliminates the central vortex and removes deposited materials, solving the problems of idling and high energy consumption caused by low liquid level at the center and high liquid level at the edge in the stirring device, and achieving an energy-saving mixing effect.

AI Technical Summary

Technical Problem

In existing mixing devices, the low center and high edge liquid level and gas-liquid vortex formed by mixing cause the blades to idle, reduce effective work, and increase unit mixing power consumption.

Method used

A flow stabilizing component is installed on the inner wall of the reactor, including mounting brackets and guide slopes distributed in a ring array. By disrupting the circumferential tangential motion of the fluid, the fluid is forced to switch to a combined axial and radial motion, eliminating the central vortex. The adaptive lifting and lowering of the guide slope removes deposited materials and reduces the flow dead zone.

Benefits of technology

It improves the effective work ratio of the stirring device, reduces the power consumption per unit of mixing effect, and reduces the ineffective energy consumption caused by liquid level difference and eddies, thus meeting the cost reduction and efficiency improvement needs of the high-energy-consuming chemical industry.

Abstract

This invention relates to the field of stirring device technology, specifically to an energy-saving mechanical stirring device. It includes a reaction vessel, with a stirring assembly at the center of the vessel for driving the rotation of materials inside. Several flow-stabilizing components are installed on the inner wall of the reaction vessel. These flow-stabilizing components are arranged in a ring array inside the reaction vessel. Each flow-stabilizing component includes a mounting frame fixed to the inner wall of the reaction vessel. The mounting frame includes several partition plates arranged sequentially along a height gradient. A guide slope is provided on the upstream side of the partition plates where the materials rotate inside the reaction vessel. The guide slope is slidably connected to the partition plates. The guide slope can adaptively rise and fall according to the material deposition, promptly removing surface deposits. Furthermore, the guide slope rises and falls using the fluid's own power, eliminating the need for additional driving components. This results in a simple structure and low operating losses, with more significant energy-saving effects during long-term continuous production, meeting the cost reduction and efficiency improvement needs of the high-energy-consuming chemical industry.
