Technical Field

[0001] The invention relates to the technical field of concentrated reaction condensation reflux for fluoride production, in particular to a concentrated reaction condensation reflux device for fluoride production. Background Art

[0002] In the production process of fluoride, a concentration process is required to evaporate the excess water in the fluoride solvent to increase the concentration of fluoride. There are many concentration processes, and the general concentration is achieved by heating.

[0003] The patent with the patent announcement number CN219764508U relates to the technical field of concentrated reaction condensation reflux for fluoride production, including a shell, a reaction chamber fixedly installed inside the shell, a support fixedly installed on one side of the outer surface of the shell, a base fixedly installed below the support, a feed pipe fixedly installed above the shell, a water tank fixedly installed inside the base, a water pump fixedly installed on one side above the water tank, a water inlet pipe fixedly connected above the water pump, a heating component fixedly connected to one end of the water inlet pipe, a steam pipe fixedly installed above the heating component, a valve fixedly installed on one side of the steam pipe, an exhaust pipe fixedly installed below one side of the shell, a solenoid valve fixedly installed above the exhaust pipe, and a heating chamber fixedly installed inside the heating component. The patent makes the utilization rate of steam higher by installing thermal insulation cotton on the inner wall of the steam pipe and a round pipe installed around the inside of the shell, thereby reducing waste.

[0004] The above patent makes steam utilization more efficient by installing heat-insulating cotton on the inner wall of the steam pipe and installing a meandering pipe around the inside of the outer shell, thereby reducing waste. However, when fluoride is put into the reactor for reaction, the amount of fluoride entering at one time may be too much. Too much fluoride entering at one time will cause the ratio of fluoride to catalyst to be too large, which may cause incomplete reaction of fluoride and catalyst. Summary of the invention

The intermittent opening of the cover plate will allow the fluoride in the feed trough to intermittently enter the reactor. The intermittent entry of fluoride into the reactor can effectively avoid excessive amount of fluoride entering at one time. Excessive amount of fluoride entering at one time will make the ratio of fluoride to catalyst too large, which may cause incomplete reaction of fluoride.

The downward movement of the hydraulic rod will push the catalyst inside the hydraulic cylinder to be discharged. Since the opening and closing plate will be opened intermittently, the hydraulic rod will push the catalyst to be discharged intermittently. Slowly adding the catalyst to the reactor can avoid the catalyst being completely consumed when reacting with fluoride, so that the ratio of fluoride to catalyst is too large, resulting in incomplete reaction of fluoride.

[0012] According to the above technical solution, the stirring device also includes a lower pressure rod, a cylinder, a long rod, a ring, a stirring plate and a scraper rod.

[0014] The present invention provides a concentrated reaction condensation reflux device for fluoride production, which has the following beneficial effects: (1) In the present invention, the rotation of the gear shaft drives the cover plate to rotate. Since the push rod intermittently pushes the push block to move, the cover plate will be intermittently opened. The intermittent opening of the cover plate will allow the fluoride in the feed trough to intermittently enter the reactor. The intermittent entry of fluoride into the reactor can effectively avoid excessive fluoride entering at one time. Excessive fluoride entering at one time will cause the ratio of fluoride to catalyst to be too large, which may cause incomplete reaction of fluoride and catalyst. The sliding rod will contact the inclined surface of the trapezoidal plate to push the trapezoidal plate to move. The movement of the trapezoidal plate will push the push plate to move away from the sliding groove. Pre-pressing the fluoride will increase the contact portion between the fluoride and the catalyst, which is beneficial to accelerate the reaction of the fluoride.

[0015] (2) In the present invention, when the fluoride slides out of the feed chute, it will enter the interior of the rolling frame. The rotation of the shaft will drive the scraper to move. The movement of the scraper will push and disperse the fluoride inside the rolling frame, making it easier to roll the fluoride. The downward movement of the protrusion will push the pressure plate to slide downward. The downward movement of the pressure plate will crush the fluoride inside the rolling frame. The crushing of the fluoride will increase the contact portion between the fluoride and the catalyst, thereby improving the efficiency of the fluoride reaction. When the pressure plate slides downward, it will push the short rod to move downward. The downward movement of the short rod will push the opening and closing plate to rotate. The rotation of the opening and closing plate will pour fluoride of sufficient size into the catalyst for reaction. Intermittently introducing fluoride into the reactor can effectively avoid excessive amount of fluoride entering at one time and avoid excessive difference in the ratio of fluoride to catalyst, which will result in incomplete reaction of the fluoride.

[0016] (3) In this invention, the downward movement of the hydraulic rod will push the catalyst inside the hydraulic cylinder to be discharged. Since the opening and closing plate will be opened intermittently, the hydraulic rod will push the catalyst to be discharged intermittently. Slowly adding the catalyst to the reactor can prevent the catalyst from being completely consumed when reacting with the fluoride, so that the ratio of fluoride to catalyst is too large, resulting in incomplete reaction of fluoride. The long rod will intermittently push the stirring plate to rotate downward, and when the long rod returns to its original position, the stirring plate will be pulled back to its original position by the No. 4 torsion spring, and the stirring plate will stir the fluoride in the process of reaction to speed up the reaction efficiency.
