DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0020] Example

[0021] like Figure 1-Figure 4 As shown: A phosphorus trichloride condensation recovery device, including: A cooling body 1 for providing cold air is an efficient and stable cooling device, and a bearing plate 2 is arranged below it to enhance the stability of the device. A fixed bracket 3 is arranged on the top of the bearing plate 2. The bracket has a strong structure and can effectively support the cooling body 1 and its auxiliary components to ensure the stable operation of the entire system.

[0022] A connecting bracket 4 is provided inside the fixed bracket 3, and the bracket is connected to the moving wheel 5 by a rotational connection. This design enables the cooling body 1 to be flexibly moved, and is convenient for the user to adjust the position as needed. At the same time, a rotating handle 6 is also rotatably connected to one end of the connecting bracket 4, and the moving wheel 5 can be easily controlled by rotating the handle 6, thereby realizing the convenient movement of the cooling body 1.

[0023] A ventilation pipe 7 is provided on one side of the cooling body 1, and one end of the ventilation pipe 7 is fixedly connected to a sealed chamber 8. A storage chamber 9 is provided inside the sealed chamber 8 for storing cooling medium or other related items. A plurality of groups of U-shaped ventilation pipes 10 for gas circulation are provided inside the storage chamber 9, and these U-shaped ventilation pipes 10 can effectively promote the circulation of gas and improve the cooling efficiency.

[0024] A rotating impeller 11 is disposed on one side of the plurality of U-shaped ventilation pipes 10, and one end of the rotating impeller 11 is fixedly connected to the output shaft of the motor 13. When the motor 13 is started, it drives the rotating impeller 11 to rotate at a high speed, thereby generating a strong airflow. The airflow is guided by the U-shaped ventilation pipe 10 to form an efficient gas circulation inside the storage bin 9, effectively taking away the heat and achieving the purpose of rapid cooling.

[0025] It can be understood that: a sealing cover 801 is provided on the top of the sealed chamber 8. The main function of this sealing cover 801 is to ensure the sealing inside the sealed chamber 8, prevent any external impurities or gas from entering, thereby ensuring the purity of the cooling medium or gas. At the same time, the top of the sealing cover 801 is also fixedly connected to the motor 13. This design not only enables the motor 13 to stably provide power for the cooling system, but also ensures that the motor 13 will not be affected by the external environment during operation, thereby extending its service life.

[0026] Inside the sealed bin 8, there is a limit block 802. The limit block 802 is fixedly connected to the storage bin 9 and mainly plays a role of positioning and supporting. Through the limit block 802, the storage bin 9 can be stably placed inside the sealed bin 8 and will not move or tilt due to external vibration or impact. This design ensures the stability of the cooling medium during storage and circulation, and improves the cooling efficiency.

[0027] An air inlet pipe 14 is provided on one side of the sealed chamber 8, and a liquid outlet pipe 15 is provided on the other side. The main function of the air inlet pipe 14 is to transport the gas required for cooling into the sealed chamber 8, while the liquid outlet pipe 15 is responsible for discharging the cooled liquid. The design of these two pipes enables the cooling medium to form a complete circulation path inside the sealed chamber 8, thereby realizing an efficient and continuous cooling process.

[0028] It is understood that a sealing gasket 12 is specially designed at one end of the ventilation pipe 7 near the sealing chamber 8. The main function of the sealing gasket 12 is to ensure that the connection between the ventilation pipe 7 and the sealing chamber 8 is highly sealed to prevent any gas or liquid leakage. By ensuring the tightness of the connection, the sealing gasket 12 not only ensures the safe and stable operation of the system, but also effectively improves the cooling efficiency.

[0029] The air intake pipe 14 is another important component of the cooling system, one end of which passes through the sealed bin 8 and is fixedly connected to the storage bin 9. This design ensures that the gas required for cooling can smoothly enter the storage bin 9 and undergo necessary cooling treatment therein. The close connection between the air intake pipe 14 and the storage bin 9 also effectively prevents gas leakage during transmission, ensuring the stability and efficiency of the cooling system.

[0030] The top of the storage bin 9 is provided with a storage bin sealing cover 901, which is designed to ensure that the cooling medium inside the storage bin will not be disturbed or contaminated by external factors. The storage bin sealing cover 901 can provide a closed environment to ensure the purity and stability of the cooling medium during storage and processing.

[0031] A rotating impeller 11 is provided at the central axis of the storage bin sealing cover 901. This design enables the rotating impeller 11 to directly contact the gas or liquid inside the storage bin, thereby generating a strong airflow through high-speed rotation, effectively removing heat from the cooling medium. One end of the rotating impeller 11 is located below the air inlet end of the U-shaped ventilation pipe 10. This layout ensures that the airflow generated by the rotating impeller 11 can smoothly enter the U-shaped ventilation pipe 10 and form an efficient gas circulation therein, further improving the cooling efficiency.

[0032] The working process of the utility model is as follows: the cooling body is the core part of the device, which is responsible for providing cold air to cool the phosphorus trichloride gas. The cooling body is connected to the sealed chamber through a ventilation pipe to form a complete cooling cycle path. A sealing gasket is provided at one end of the ventilation pipe close to the sealed chamber to ensure the sealing of the connection and prevent gas leakage.

[0033] A storage bin is provided inside the sealed bin for cooling phosphorus trichloride and storing the condensed phosphorus trichloride liquid. The storage bin is fixedly connected to the inside of the sealed bin through a limit block to ensure its stability during operation. At the same time, a sealing cover is provided on the top of the sealed bin to ensure the sealing of the bin and prevent external impurities or gas from entering.

[0034] The motor is fixed on the top of the sealing cover, and its output shaft is fixedly connected to one end of the rotary impeller. When the motor is started, it drives the rotary impeller to rotate at high speed. The rotary impeller is located at the central axis of the storage bin sealing cover, and the strong airflow generated by its rotation can effectively make the airflow pass through the U-shaped ventilation pipe to circulate and cool inside.

[0035] One end of the air inlet pipe passes through the sealed bin and is fixedly connected to the storage bin. The main function of the air inlet pipe is to introduce the phosphorus trichloride gas to be condensed into the storage bin. When the gas enters the storage bin, it will meet the airflow generated by the rotating impeller, transfer heat to the airflow through heat exchange and be condensed into liquid.

[0036] The liquid outlet pipe is located at the other side of the sealed bin and is used to discharge the condensed phosphorus trichloride liquid from the storage bin. In this way, through the cyclic operation of the entire device, the phosphorus trichloride gas can be effectively condensed and recovered as a liquid state.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
