Description

Technical Field

[0001] This utility model relates to the field of sodium cyanide preparation technology, and in particular to a temperature control device for sodium cyanide production equipment. Background Technology

[0002] Sodium cyanide production requires an evaporation and crystallization process. This is typically achieved by adjusting the temperature of the sodium cyanide solution to crystallize it, as disclosed in utility model patent CN207259166U and utility model patent CN207253780U.

[0003] However, during use, it was found that the existing crystallization equipment has a relatively simple structure, high energy consumption, and inconvenient sodium cyanide discharge after crystallization, resulting in poor practicality. Therefore, there is an urgent need for a temperature control device for sodium cyanide production equipment to improve the above problems.

[0004] In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a temperature control device for sodium cyanide production equipment to overcome the problems existing in the prior art. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a temperature control device for sodium cyanide production equipment. The device involves pouring a sodium cyanide solution into a heating mechanism to heat the solution, while simultaneously regulating the pressure within the heating mechanism to create a negative pressure environment. A recovery mechanism also recovers the distilled water generated during heating. After the sodium cyanide crystallizes, the crystallized sodium cyanide is discharged through the pressure regulation mechanism, thereby improving the practicality of the equipment.

[0006] This utility model discloses a temperature control device for sodium cyanide production equipment, which includes a heating mechanism; it also includes a pressure regulating mechanism and a recovery mechanism, both of which are installed on the heating mechanism; The heating mechanism stores and heats the sodium cyanide solution, the pressure regulating mechanism regulates the pressure inside the heating mechanism, and the recovery mechanism recovers the distilled water. The sodium cyanide solution is poured into the heating mechanism, which heats the solution. Simultaneously, the pressure inside the heating mechanism is regulated to create a negative pressure environment. The distilled water generated during heating is recovered by the recovery mechanism. After the sodium cyanide crystallizes, the crystallized sodium cyanide is discharged through the pressure regulation mechanism, thereby improving the practicality of the equipment.

[0007] Furthermore, the heating mechanism includes a base, a heating cylinder, a feed pipe, a feed valve, and a feed hopper. The heating cylinder is mounted on the base, and a heating element is provided in the side wall of the heating cylinder. The feed valve is mounted on the top of the heating cylinder through the feed pipe, and the feed hopper is mounted on the top of the feed valve. When the feed valve is opened, the sodium cyanide solution is poured into the feed hopper, so that the sodium cyanide solution flows sequentially through the feed valve and the feed pipe into the heating cylinder, where the heating cylinder heats the sodium cyanide solution.

[0008] Furthermore, the pressure regulating mechanism includes two sets of hydraulic cylinders, two sets of fixed brackets, and two sets of pistons. A discharge port is provided on the bottom side of the heating cylinder. Both sets of fixed brackets are installed on the heating cylinder, and the two sets of hydraulic cylinders are respectively fixedly installed on the two sets of fixed brackets. Both sets of pistons are slidably installed in the heating cylinder, and one end of each set of hydraulic cylinders is connected to the side end of the two sets of pistons. After the sodium cyanide solution is poured into the heating cylinder, the feed valve is closed. The two sets of hydraulic cylinders contract, causing the two sets of pistons to slide in opposite directions, thereby creating a negative pressure environment inside the heating cylinder. After the sodium cyanide in the heating cylinder has crystallized, one set of hydraulic cylinders contracts and the other set of hydraulic cylinders extends, causing the two sets of pistons to slide in the same direction, pushing the crystallized sodium cyanide to the discharge port of the heating cylinder, and discharging the crystallized sodium cyanide through the discharge port.

[0009] Furthermore, annular scrapers are provided on the opposing surfaces of the two sets of pistons; the annular scrapers scrape off the residue on the inner wall of the heating cylinder.

[0010] Furthermore, an electrically controlled pressure relief valve is installed on the feed pipe; after the sodium cyanide crystallization is completed, the electrically controlled pressure relief valve is opened to restore the internal pressure of the heating cylinder to normal.

[0011] Furthermore, the recycling mechanism includes a guide channel, a water collection tank, a guide pipe, and a drain valve. The guide channel is installed in the feed pipe, the water collection tank is installed on the top of the heating cylinder, and the water collection tank is connected to the interior of the guide channel through the guide pipe. The drain valve is installed on the water collection tank. The distilled water condensed in the feed pipe is collected through the guide channel, and the distilled water in the guide channel is introduced into the water collection tank through the guide pipe. After the equipment is stopped, the distilled water in the water collection tank is discharged by opening the drain valve.

[0012] Furthermore, it also includes multiple sets of rotating shafts, two sets of conveyor belts, and two sets of drive motors. The multiple sets of rotating shafts are rotatably mounted on the base, the two sets of conveyor belts are respectively fitted onto the multiple sets of rotating shafts, and the two sets of drive motors are fixedly mounted on the base. The output shafts of the two sets of drive motors provide power to the multiple sets of rotating shafts. By turning on the two sets of drive motors, the two sets of conveyor belts are driven to run through the multiple sets of rotating shafts, thus sending out the crystallized sodium cyanide discharged from the heating cylinder.

[0013] Compared with the prior art, the present invention has the following advantages: The sodium cyanide solution is poured into the heating mechanism, which heats the solution. Simultaneously, the pressure inside the heating mechanism is regulated to create a negative pressure environment. The distilled water generated during heating is recovered by the recovery mechanism. After the sodium cyanide crystallizes, the crystallized sodium cyanide is discharged through the pressure regulation mechanism, thereby improving the practicality of the equipment.

The sodium cyanide solution flows sequentially through the feed valve 4 and the feed pipe 3 into the heating cylinder 2. Then close the feed valve 4 and heat the sodium cyanide solution through the heating cylinder 2. The two sets of hydraulic cylinders 6 contract, causing the two sets of pistons 8 to slide in opposite directions, thereby creating a negative pressure environment inside the heating cylinder 2, which accelerates the evaporation rate of water. The distilled water condensed in the feed pipe 3 is collected through the guide channel 12 and guided into the water collection tank 13 through the guide pipe 14. After the sodium cyanide in the heating cylinder 2 has crystallized, one set of hydraulic cylinders 6 contracts and the other set of hydraulic cylinders 6 extends, causing the two sets of pistons 8 to slide in the same direction. At the same time, the annular scraper 10 scrapes off the residue on the inner wall of the heating cylinder 2 and pushes the crystallized sodium cyanide to the discharge port 9 of the heating cylinder 2. The crystallized sodium cyanide is discharged through the discharge port 9, thereby improving the practicality of the equipment.

Afterward, close the feed valve 4. The heating cylinder 2 heats the sodium cyanide solution. The contraction of two sets of hydraulic cylinders 6 causes two sets of pistons 8 to slide in opposite directions, creating a negative pressure environment inside the heating cylinder 2. This accelerates the evaporation of water. The distilled water condensed in the feed pipe 3 is collected through the guide channel 12 and guided into the water collection tank 13 through the guide pipe 14, ready for further processing. After the sodium cyanide crystallizes in the heating cylinder 2, one set of hydraulic cylinders 6 contracts while another set extends, causing the two sets of pistons 8 to slide in the same direction. At the same time, the annular scraper 10 scrapes off the residue on the inner wall of the heating cylinder 2, pushing the crystallized sodium cyanide to the discharge port 9 of the heating cylinder 2.
