Reaction kettle for suspension stirring type chemical engineering

Abstract

The invention discloses a suspension stirring type reaction kettle for chemical industry, which comprises a kettle body, a motor, a feeding hopper and a liquid outlet pipe; A horizontal turntable is fixed, and a vertical feeding hole is opened on the turntable. The bottom of the feeding box is provided with a feeding opening. The suspension stirring structure includes guide rails, sliding sleeves, limit grooves, suspension stirring blades, and floating balls. and a limit ring; the stirring mechanism includes a support frame, a liquid guiding cylinder, a helical stirring blade, a driven gear and a driving gear; the bottom of the kettle directly below the liquid guiding cylinder is provided with a downwardly recessed turbulence cavity. The powder falling on the upper surface of the liquid can be stirred by the suspension stirring blade, so that the powder can quickly enter the liquid, improve the mixing efficiency of the powder, and adapt to the rapid progress of different reaction materials; the spiral stirring blade in the guide tube rotates , so that the liquid above flows rapidly downward and spreads outward from the bottom.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a suspension stirring type chemical reaction kettle. Background technique [0002] The reaction kettle is a kind of equipment widely used in chemical production. It can stir and mix various chemical reagents, so that different raw materials can be evenly mixed and fully reacted. The existing chemical reaction kettle is generally equipped with a feed port, and the raw material liquid is directly poured into the tank body through the feed port. When one raw material is poured into another raw material for mixing or reaction, this equipment cannot The feed liquid poured in last is quickly and uniformly dispersed, and the feed liquid that enters last is collected in the area corresponding to the feed inlet of the inner cavity of the reaction kettle, and then stirred by the stirring device. In this way, the raw materials enter too fast and cannot be uniformly dispersed, which can easily lead to ...

AI Technical Summary

Problems solved by technology

The existing chemical reaction kettle is generally equipped with a feed port, and the raw material liquid is directly poured into the tank body through the feed port. When one raw material is poured into another raw material for mixing or reaction, this equipment cannot Quickly and evenly disperse the feed liquid that is poured in last, and collect the feed liquid that enters in the area corresponding to the feed port of the inner cavity of the reactor, and then stir it through the stirring device

In this way, the raw materials enter too fast and cannot be uniformly dispersed, which can easily lead to the local raw material mixing ratio is too high, the raw materials are united and agglomerated, or the local reaction speed is too fast, especially in some processes, such as adding acid, adding In the alkali reaction, if the local addition is too fast and cannot be quickly dispersed, it is easy to cause local acid and alkali excess, resulting in product quality degradation, failure to achieve the expected reaction effect, and product performance changes; in addition, when powdered raw materials are added When the raw material is light, it is suspended on the surface of the liquid, and the agitation of the liquid cannot make the powder mix quickly, which affects the reaction efficiency; therefore, it is necessary to improve the existing reaction kettle to solve the above problems
