Description

Technical Field

[0001] This invention relates to the field of deuterium gas preparation technology, and more particularly to a heavy water recovery device for a deuterium gas generator. Background Technology

[0002] Deuterium is a colorless, odorless, and non-toxic combustible gas that can be used in the chemical and biochemical fields to produce compounds containing deuterium. Deuterium generators are commonly used equipment for preparing deuterium.

[0003] According to the public announcement (CN113883912A), the existing device has the following problem: some gas forms a water film on the inner wall of the condenser tube, which adheres to the inner wall. This water film cannot condense into water droplets and fall off due to surface tension, resulting in gas waste and making it difficult for the device to fully recover heavy water. Therefore, it is necessary to improve upon the above-mentioned problems in the existing technology and to redesign a heavy water recovery device for a deuterium generator. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing devices are difficult to fully recover heavy water, and to propose a heavy water recovery device for a deuterium generator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The cooling box is provided with a positioning hole, and a drive motor is provided on the positioning rod. A drive gear is rotatably provided on the upper end face of the cooling box. The drive motor is connected to the drive gear through a snap-fit ​​mechanism. A screw is rotatably provided on the cooling box through a support plate. The screw is connected to the drive gear through a rotation mechanism. A scraper ring is provided inside the condenser tube. The scraper ring is connected to the screw through a connecting mechanism.

[0008] Preferably, the upper lifting mechanism includes an upper lifting spring disposed in the upper lifting groove, and the two ends of the upper lifting spring are elastically connected to the outer wall of the positioning rod and the bottom wall of the upper lifting groove, respectively.

[0014] The beneficial effects of this invention are:

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1-5 A heavy water recovery device for a deuterium generator includes a cooling tank 1, a collection tank 2, a heat exchange device 8, and a condenser tube 19. The heat exchange device 8 is connected to the cooling tank 1. The cooling tank 1 and the collection tank 2 are connected by a support rod 3. The condenser tube 19 and the collection tank 2 are connected by a collection pipe 4. The liquid finally enters the collection tank 2 through the collection pipe 4 to complete the collection.

[0026] The cooling box 1 is provided with a mounting groove 9, and a mounting rod 10 is provided in the mounting groove 9. The mounting rod 10 is provided with an upper top groove 21. A positioning rod 12 is provided in the upper top groove 21 through an upper top mechanism. The cooling box 1 is provided with a positioning hole 11. A drive motor 13 is provided on the positioning rod 12. A drive gear 14 is rotatably provided on the upper end face of the cooling box 1. The drive motor 13 is connected to the drive gear 14 through a snap-fit ​​mechanism. A screw 17 is rotatably provided on the cooling box 1 through a support plate. The screw 17 is connected to the drive gear 14 through a rotation mechanism. A scraper ring 20 is provided in the condenser pipe 19. The scraper ring 20 is connected to the screw 17 through a connecting mechanism.

[0027] The upper lifting mechanism includes an upper lifting spring 22 disposed in the upper lifting groove 21. The two ends of the upper lifting spring 22 are elastically connected to the outer wall of the positioning rod 12 and the inner bottom wall of the upper lifting groove 21, respectively. The upper lifting spring 22 realizes the upper lifting operation of the positioning rod 12 and can push it into the positioning hole 11.

[0028] The snap-fit ​​mechanism includes a snap-fit ​​rod 15 connected to the output shaft of the drive motor 13, and a snap-fit ​​groove 16 corresponding to the snap-fit ​​rod 15 on the drive gear 14. Both the snap-fit ​​rod 15 and the snap-fit ​​groove 16 have rectangular cross-sectional views.

[0029] The rotating mechanism includes a transmission gear 18 connected to the screw 17, a drive gear 14 meshing with the transmission gear 18, and both the drive gear 14 and the two transmission gears 18 are bevel gears.

[0030] The connecting mechanism includes a threaded sleeve 5 that is threadedly connected to the screw 17. The threaded sleeve 5 is connected to the scraper ring 20 through the fixing plate 6 and the connecting rod 7. The connecting rod 7 slides through the condenser pipe 19 and the cooling box 1 and is connected to the fixing plate 6, which makes the threaded sleeve 5 have a limiting function to prevent it from rotating with the screw 17.

[0031] In use, the electrolytic gas is introduced into the condenser tube 19, the circulation pump assembly in the heat exchange device 8 is started, the cooling tank 1 is filled with cooling water, the circulation pump assembly in the heat exchange device 8 draws out the water in the cooling tank 1, and the cooling is completed by the heat exchanger assembly in the heat exchange device 8. Then the circulation pump assembly in the heat exchange device 8 pumps the low-temperature water flow into the cooling tank 1 to realize the circulation of water flow. When the low-temperature water flow flows around the condenser tube 19, it can carry away the heat on the surface of the condenser tube 19, ensuring the cooling effect of the condenser tube 19 on the gas, so that the electrolytic gas is liquefied inside the condenser tube 19, and then collected into the collection tank 2 through the collection pipe 4.

[0032] The drive motor 13 can drive the drive gear 14 to rotate via the snap-fit ​​rod 15. The drive gear 14 can drive the screw 17 to rotate via the transmission gear 18. When the screw 17 rotates, the threaded sleeve 5 can work with the fixing plate 6 and the connecting rod 7 to drive the scraper ring 20 to move inside the horizontal part of the condenser tube 19, which can scrape off the water film for collection.

[0033] Pressing the positioning rod 12 inside the positioning hole 11 can separate the two, thereby releasing the fixed installation of the mounting rod 10 relative to the mounting groove 9. Moving the mounting rod 10 laterally can drive the drive motor 13 assembly to complete the disassembly operation, making it convenient for inspection, maintenance and replacement.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
