Description

Technical Field

[0001] The utility model relates to an esterification accelerating device, belonging to the field of stirring equipment. Background Art

[0002] Esterification reaction is a type of organic chemical reaction, which is the reaction between alcohol and carboxylic acid or oxygen-containing inorganic acid to produce ester and water. It is divided into three categories: reaction between carboxylic acid and alcohol, reaction between inorganic oxygen-containing acid and alcohol, and reaction between inorganic strong acid and alcohol. In order to increase the reaction speed, stirring is needed to accelerate the esterification reaction.

[0003] In the prior art, the stirring rod inside the esterification acceleration device is usually horizontal or vertical. During the stirring process of the liquid, a vortex is generated, which makes it impossible for the catalyst in the center of the vortex to be quickly and fully mixed with the liquid at the outer edge of the vortex. The spoiler rod installed inside the kettle body can only disrupt the large vortex into a small vortex, and cannot avoid the phenomenon of idling in the center of the liquid, thereby reducing the efficiency of the liquid esterification reaction.

[0004] In summary, the present invention provides an esterification acceleration device to solve the above problems. Utility Model Content

[0010] Furthermore, the acceleration mixer includes a connecting pipe and two stirring frames, the two stirring frames are respectively fixedly connected to the opposite ends of the two driving shafts, and the opposite sides of the two stirring frames are open. The connecting pipe is fixedly connected to the top of the transmission shaft and is located between the opposite sides of the two stirring frames. The top of the connecting pipe passes through the top of the inner wall of the esterification kettle body and extends to the top of the esterification kettle body. Both sides of the connecting pipe surface and the openings located on the opposite sides of the two stirring frames are connected with dosing pipes. The front sides of the two dosing pipes are evenly connected with multiple one-way valves from left to right. Stirring rods are fixedly connected to both sides of the connecting pipe and located directly above and directly below the two stirring frames.

[0011] Furthermore, the top end of the connecting tube is rotatably connected to the infusion tube, and the connecting tube is communicated with the infusion tube.

[0012] Furthermore, the connecting pipe is rotatably connected to the esterification kettle body, and the separated ends of the two dosing pipes extend into the interiors of the two stirring frames respectively through openings on opposite sides of the two stirring frames.

[0013] Beneficial effects of the utility model:

[0014] By starting the first motor and the two second motors, the first motor drives the connecting pipe, the two dosing pipes and the four stirring rods to rotate horizontally inside the esterification kettle body through the transmission shaft, thereby generating a longitudinal stirring vortex. The two second motors drive the two drive shafts to rotate, and the two drive shafts drive the two stirring frames to rotate between two upper and lower adjacent stirring rods respectively. The generated transverse stirring vortex will disrupt the longitudinal vortex generated by the rotation of the dosing pipes and the stirring rods, thereby avoiding the phenomenon of idling stirring of the liquid inside the esterification kettle body caused by the occurrence of a unidirectional stirring vortex, thereby effectively improving the efficiency of the liquid esterification reaction.

[0025] See also Figure 2-4The accelerating mixer 9 includes a connecting pipe 91 and two stirring frames 92. The two stirring frames 92 are respectively fixedly connected to the opposite ends of the two driving shafts 10. The opposite sides of the two stirring frames 92 are open. The connecting pipe 91 is fixedly connected to the top of the transmission shaft 6 and is located between the opposite sides of the two stirring frames 92. The top of the connecting pipe 91 passes through the top of the inner wall of the esterification kettle body 3 and extends to the top of the esterification kettle body 3. Both sides of the connecting pipe 91 and the openings on the opposite sides of the two stirring frames 92 are connected with dosing pipes 93. The front faces of the two dosing pipes 93 are evenly connected with multiple one-way valves 95 from left to right. Stirring rods 94 are fixedly connected to both sides of the connecting pipe 91 and located just above and just below the two stirring frames 92. The bottom end of the cavity inside 1 is located below the port of the dosing tube 93, so that the catalyst transported inside the connecting tube 91 can be fully transported to the interior of the two dosing tubes 93. The water pressure can open the one-way valve 95 and discharge the catalyst from the two dosing tubes 93 to the interior of the esterification kettle body 3 and mix with the liquid.

The separated ends of the two dosing tubes 93 extend to the interior of the two stirring frames 92 through the openings on the opposite sides of the two stirring frames 92.

[0026] Specific implementation method: By opening the liquid inlet pipe 11, the liquid that has not been esterified is pumped from the liquid inlet pipe 11 to the inside of the esterification kettle body 3, and then the catalyst is transported to the inside of the connecting pipe 91 through the liquid infusion pipe 14. The bottom end of the cavity inside the connecting pipe 91 is located below the port of the dosing pipe 93, so that the catalyst transported inside the connecting pipe 91 can be completely transported to the inside of the two dosing pipes 93. The water pressure can open the one-way valve 95, and the catalyst is discharged from the two dosing pipes 93 to the inside of the esterification kettle body 3 and mixed with the liquid, thereby avoiding the phenomenon of the catalyst floating on the water surface of the liquid inside the esterification kettle body 3, and accelerating the efficiency of the catalyst integrating into various parts of the liquid.

[0027] The first motor 5 and the two second motors 8 are started at the same time. The first motor 5 drives the connecting pipe 91 to rotate through the transmission shaft 6. The connecting pipe 91 can simultaneously drive the two dosing pipes 93 and the four stirring rods 94 to rotate horizontally inside the esterification kettle body 3, thereby generating a longitudinal stirring vortex and stirring the liquid inside the esterification kettle body 3 to accelerate the mixing of the catalyst. The two second motors 8 drive the two drive shafts 10 to rotate. The two drive shafts 10 simultaneously drive the two stirring frames 92 to rotate between the two upper and lower adjacent stirring rods 94, respectively. The generated transverse stirring vortex will disrupt the longitudinal vortex generated by the rotation of the dosing pipe 93 and the stirring rod 94, thereby avoiding the phenomenon of idling stirring of the liquid inside the esterification kettle body 3, effectively improving the efficiency of the liquid esterification reaction, and the bayonet between the opposite sides of the two stirring frames 92 does not affect the normal rotation of the two dosing pipes 93.

[0028] After the esterification reaction, the grease and water in the liquid will produce a water-oil separation phenomenon, and the grease will float on the water surface. The liquid is continuously transported to the interior of the esterification kettle body 3 through the liquid inlet pipe 11. As the water level inside the esterification kettle body 3 rises, the grease can be pushed upward. The valve on the discharge pipe 13 is opened to discharge the grease in a centralized manner. After the discharge is completed, the valve on the liquid outlet pipe 12 can be opened to discharge the wastewater containing residual grease for secondary filtration.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
