AI Technical Summary
In existing chemical reactors, the catalyst is not added in time, which affects the reaction efficiency; the discharge pipeline is prone to blockage, affecting the discharge performance.
A high-efficiency emulsion reactor was designed, using a rotary joint to connect the catalyst dropper tube and the feed tube. The catalyst dropper tube was set obliquely, combined with the vortex center of the agitator to ensure the uniform action of the catalyst. A thimble valve is installed at the bottom of the discharge pipe to prevent raw materials from remaining and clogging.
The rapid and even addition of catalyst is achieved, and the reaction efficiency is improved. Through the design of the thimble valve, the discharge pipeline is avoided and the stability of the discharge is ensured.

Abstract
Description
Technical Field
[0001] The utility model relates to a chemical reaction kettle, in particular to a high-efficiency emulsion reaction kettle. Background Art
[0002] In the existing reaction kettles for chemical production, most of the catalysts are added by flowing along the wall and into the kettle. The catalyst cannot flow into the raw materials in the first time, and the functions of catalyzing and stabilizing the reaction are greatly affected. In addition, for the bottom pipeline discharging of the reaction kettle, after the cut-off valve is opened for discharging and then closed, the emulsion remains in the discharging pipeline, which is extremely easy to polymerize in the pipeline and even block the pipeline, affecting the discharging performance and normal discharging. Summary of the Invention
[0003] The utility model provides a high-efficiency emulsion reaction kettle with simple structure, which can effectively ensure the efficient addition of catalyst and stable discharging.
[0004] The technical scheme adopted by the utility model is as follows: a high-efficiency emulsion reaction kettle, including a kettle body, a stirrer is arranged in the center of the kettle body. It is characterized in that: a rotary joint is hermetically penetrated through the upper end of the kettle body, the rotary joint is connected with a catalyst dropping pipe into the kettle body, the catalyst dropping pipe is obliquely arranged towards the center of the kettle body, the rotary joint is connected with a catalyst feeding pipe outside the kettle body, and a flowmeter is arranged on the catalyst feeding pipe; a discharging pipe with a thimble valve is arranged at the bottom of the kettle body.
[0005] Inner and outer marks corresponding to the catalyst dropping pipe facing the center of the kettle body or facing the outside of the kettle body are arranged on the upper end of the kettle body around the rotary joint.
[0006] An electric actuator for driving the rotary joint to rotate is externally connected to the upper end of the kettle body.
[0007] A feed cut-off valve is further arranged on the catalyst feeding pipe in front of the flowmeter.
[0008] A Venturi tube section is arranged on the catalyst dropping pipe.
[0009] The beneficial effects of the utility model are as follows:
[0010] 1. The catalyst dropping pipe is obliquely arranged towards the center, and the catalyst outlet corresponds to the center of the vortex formed by the stirring of the stirrer. Adding the catalyst at the center of the vortex is beneficial to ensure the rapid and uniform action of the catalyst. And a flowmeter is added, and the dropping is more stable, changing from manual metering to automatic. Combining the feed cut-off valve on the catalyst feeding pipe and the Venturi tube structure helps to control the catalyst flow rate and accelerate the rapid feeding and dropping of the viscous catalyst liquid.
[0011] 2. By adopting the thimble valve, when the discharging pipe is opened and closed for discharging, the thimble is stuck, and the raw materials will not remain in the discharging pipeline, and it is not easy to cause blockage.
[0012] 3. The catalyst dropping pipe is provided with a rotary joint, and the rotary joint can be rotated manually or electrically controlled by an electric actuator, so that the catalyst dropping pipe can be rotated inwards or outwards. The orientation of the catalyst dropping pipe can be adjusted, so that the catalyst falls at different positions of the stirring vortex in the kettle, meeting the dropping requirements of different catalysts, and it can be folded outwards, which is convenient for the placement and removal of the internal stirrer. With the internal and external markings on the rotary joint, the orientation of the catalyst dropping pipe in the kettle can be visually seen. Brief Description of the Drawings
