Description

Technical Field

[0001] This utility model relates to the field of liquid carbon dioxide injection technology, specifically to a liquid carbon dioxide injection device. Background Technology

[0002] Liquid carbon dioxide injection plays a crucial role in many fields. In chemical production, it participates in reactions as a raw material to synthesize a variety of important products. In the metallurgical industry, it can be used as a reducing agent to extract and refine metals.

[0003] For example, a high-pressure liquid carbon dioxide injection system with authorization publication number "CN116734171A" controls the inlet conditions of the high-pressure liquid carbon dioxide injection equipment to improve its pressurization efficiency. The system employs a novel pump cooling process, utilizing oil cooling, a leak detection system, and a fully sealed, leak-free process to ensure the pump operates at the correct temperature. However, traditional liquid carbon dioxide injection devices can only inject liquid carbon dioxide into one receiving container at a time. In industrial production, if a large number of receiving containers need to be injected with liquid carbon dioxide, the process of injecting each container individually is cumbersome, requiring repeated connection, injection, and disassembly steps. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional liquid carbon dioxide injection devices can only inject liquid carbon dioxide into one receiving container at a time, and to propose a liquid carbon dioxide injection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a liquid carbon dioxide injection device, including a housing and an outlet pipe. The lower end of the housing is fixedly connected to multiple outlet pipes. A solenoid valve is installed inside the outlet pipe. A liquid carbon dioxide injection structure is provided on the outer wall of the outlet pipe. A shell is fixedly connected to the upper end of the housing. A liquid carbon dioxide mixing structure is provided inside the shell.

[0007] Preferably, the liquid carbon dioxide injection structure includes a first thread, the outer wall of the outlet pipe is machined with a first thread, the first thread is connected to a second thread, the inner wall of the circular pipe is provided with a second thread, the lower end of the circular pipe is fixedly connected to a bellows, and a first valve is installed on the inner wall of the bellows.

[0008] Preferably, support legs are fixedly connected to both sides of the lower end of the box.

[0009] Preferably, the liquid carbon dioxide mixing structure includes a servo motor, the outer wall of which is threadedly connected to the housing by bolts, the output shaft of which is fixedly connected to the rotating shaft of the first gear, the upper end of the rotating shaft of the first gear is rotatably connected to the housing by a bearing, the first gear and the second gear are meshed together, and the lower ends of the rotating shafts of the first gear and the second gear are both fixedly connected to a stirring rod, the upper side of the outer wall of the stirring rod being rotatably connected to the housing by a sealed bearing.

[0012] The present invention provides a liquid carbon dioxide injection device with the following advantages: By cooperating with the liquid carbon dioxide injection structure and the outlet pipe, the first valve is opened, the corrugated pipe is inserted into the collection container, and the solenoid valve is opened. The liquid carbon dioxide in the tank flows through the outlet pipe, the round pipe and the corrugated pipe due to gravity, and finally flows into the collection container. The corrugated pipe has extensibility to ensure that the corrugated pipe can be smoothly inserted into the collection container.

Liquid carbon dioxide can be injected into multiple collection containers at one time. Attached Figure Description

A housing 5 is fixedly connected to the upper end of the housing 1. A maintenance door is installed at the front end of the housing 5. A liquid carbon dioxide mixing structure 6 is provided inside the housing 5. Support legs 9 are fixedly connected to both sides of the lower end of the housing 1. The right end of the housing 1 is fixedly connected to an inlet pipe 7. A second valve 8 is installed inside the inlet pipe 7. The second valve 8 can prevent foreign objects from entering the inlet pipe 7 when it is not in use.

[0022] See attached document Figure 1 , Figure 3 and Figure 4 The liquid carbon dioxide injection structure 4 includes a first thread 401. The outer wall of the outlet pipe 2 is machined with the first thread 401. The first thread 401 is threadedly connected to the second thread 403. The inner wall of the round pipe 402 is provided with the second thread 403. The lower end of the round pipe 402 is fixedly connected to the bellows 404. The inner wall of the bellows 404 is equipped with a first valve 405. The first valve 405 can prevent foreign objects from entering the bellows 404.

[0023] See attached document Figure 1 , Figure 2 and Figure 5 The liquid carbon dioxide mixing structure 6 includes a servo motor 601. The outer wall of the servo motor 601 is threadedly connected to the housing 5 by bolts. The servo motor 601 is mounted on the housing 5 by bolts. The output shaft of the servo motor 601 is fixedly connected to the rotating shaft of the first gear 602. The upper end of the rotating shaft of the first gear 602 is rotatably connected to the housing 5 by a bearing. The rotating shaft of the first gear 602 rotates inside the housing 5 by the bearing. The first gear 602 is meshed with the second gear 603. The lower ends of the rotating shafts of the first gear 602 and the second gear 603 are fixedly connected to a stirring rod 604.

[0024] Working principle

[0025] When using a liquid carbon dioxide injection device:

[0026] During storage, liquid carbon dioxide may exhibit uneven composition due to factors such as temperature and pressure changes. When the external power supply to the servo motor 601 is connected, the servo motor 601 is started, and the output shaft of the servo motor 601 rotates, driving the first gear 602 to rotate (e.g., ...). Figure 2 The rotation of the first gear 602 drives the rotation of the second gear 603. To further explain, the two gears rotate in opposite directions. The rotation of the two gears drives the stirring rod 604 to rotate. The rotation of the stirring rod 604 ensures that the liquid carbon dioxide in the chamber is fully mixed, thus avoiding concentration differences.

[0027] Injection of liquid carbon dioxide:

[0028] The collection container is placed below the bellows 404. The first valve 405 is opened, and the bellows 404 is inserted into the collection container. The solenoid valve 3 is opened, and the liquid carbon dioxide in the tank 1 flows by gravity through the outlet pipe 2, the circular pipe 402, and the bellows 404, finally flowing into the collection container. Furthermore, the bellows 404 is extendable, ensuring that it can be smoothly inserted into the collection container. A sealing rubber ring is installed at the connection between the first thread 401 and the second thread 403 to prevent leakage of liquid carbon dioxide. The amount injected into the collection container each time is controlled by the number of times the solenoid valve 3 is opened, thereby achieving the purpose of diversion. The device can inject liquid carbon dioxide into multiple collection containers at once. After the liquid carbon dioxide injection is completed, the solenoid valve 3 is closed, the bellows 404 is removed from the collection container, and the first valve 405 is inserted into the bellows 404. The first valve 405 can prevent the entry of foreign objects. The collection container is then removed. To further explain, liquid carbon dioxide can be supplied to the tank 1 through the liquid inlet pipe 7. The second valve 8 can prevent foreign objects from entering the liquid inlet pipe 7 when it is not in use. Operators can periodically inspect the equipment inside the housing 5 through the maintenance door at the front of the housing 5. The amount of liquid carbon dioxide in the tank 1 can be viewed through the observation window at the front of the tank 1.
