Description

Technical Field

[0001] This invention relates to the field of condenser technology, and in particular to a condenser. Background Technology

[0002] The working principle of the iodine-based electric propulsion equipment is as follows: In the vacuum working chamber, the iodine source is ionized by high energy to generate iodine plasma flame, which generates propulsion in the vacuum. Iodine vapor is in a low-pressure and low-temperature environment in the vacuum pipeline. Due to the low pressure, the condensation effect is poor. Once it enters the vacuum pump, the iodine vapor enters the high-pressure and low-temperature environment, which accelerates the condensation of iodine and damages the vacuum pump. Summary of the Invention

[0003] The purpose of this invention is to provide a condenser that allows iodine vapor to undergo pressure boosting before entering the vacuum pump, achieving efficient condensation at low temperature and high pressure, and effectively protecting the vacuum pump.

[0004] To achieve the above objectives, the present invention provides the following solution:

[0005] The present invention provides a condenser, including a housing and a compression structure. The housing is provided with a cooling channel, and the compression structure is located in the housing. The compression structure includes a drive structure and a plurality of rotating blades. The housing is provided with an intake port and an exhaust port, both of which are connected to the interior of the housing. As the drive structure drives the rotating blades to move, the space between adjacent rotating blades gradually decreases from the intake port to the exhaust port.

[0006] Preferably, the compression structure further includes an eccentric rotor, and a plurality of the rotating blades are arranged circumferentially along the eccentric rotor.

[0007] Preferably, one end of each of the rotating blades is in contact with the inner wall of the housing.

[0008] Preferably, an elastic element is provided between the other end of each of the rotating blades and the eccentric rotor.

[0009] Preferably, the elastic element is a spring.

[0010] Preferably, the air intake and the air exhaust are arranged opposite to each other.

[0011] Preferably, the housing is further provided with an oil inlet and an oil outlet, both of which are in communication with the interior of the housing.

[0012] Preferably, the oil inlet and the oil outlet are arranged opposite to each other.

[0013] Preferably, the housing has a double-layer structure, and the cooling channel is located in the double-layer structure.

[0014] The present invention achieves the following technical effects compared to the prior art:

[0015] The condenser in this invention uses a volume compression method, which increases the pressure of iodine vapor in the vacuum pipe between the condenser and the vacuum pump. This allows iodine to be pressurized in advance before entering the vacuum pump, achieving efficient condensation at low temperature and high pressure. The iodine is then captured and collected by the condenser, greatly improving the iodine recovery efficiency and effectively protecting the vacuum pump system. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide a condenser that allows iodine vapor to undergo pressure boosting before entering the vacuum pump, achieving efficient condensation at low temperature and high pressure, and effectively protecting the vacuum pump.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1As shown: This embodiment provides a condenser, including a shell 1 and a compression structure. The shell 1 has a double-layer structure, with a cooling channel 2 located within the double-layer structure. The cooling channel 2 is used to introduce a cooling medium. The compression structure is located within the shell 1 and includes a drive structure and several rotating blades 3. The drive structure can be a motor. The shell 1 is provided with an intake port 5 and an exhaust port 6, which are arranged opposite to each other and are both connected to the interior of the shell 1. As the drive structure drives the rotating blades 3 to move, the space between adjacent rotating blades 3 gradually decreases from the intake port 5 to the exhaust port 6. Gas enters between adjacent rotating blades 3 through the intake port 5. As the rotating blades 3 move, the space formed between adjacent rotating blades 3 and the shell 1 gradually decreases, pressurizing the gas during this process. The pressurized condensation of the gas is also achieved through contact cooling between the gas and the shell 1.

[0023] Specifically, in this embodiment, the compression structure also includes an eccentric rotor 9, and a plurality of rotating blades 3 are arranged along the circumference of the eccentric rotor 9. The driving structure drives the eccentric rotor 9 to rotate. During the rotation, one end of each rotating blade 3 contacts the inner wall of the housing 1, so that adjacent rotating blades 3 and the housing 1 between them form a sealed environment. An elastic element 4 is provided between the other end of each rotating blade 3 and the eccentric rotor 9. The elastic element 4 is a spring.

[0024] In this embodiment, the housing 1 is also provided with an oil inlet 7 and an oil outlet 8, which are arranged opposite to each other. The oil outlet 8 is located at the bottom of the housing 1, and both the oil inlet 7 and the oil outlet 8 are connected to the interior of the housing 1. Vacuum oil or silicone oil is selected as the lubricating grease. The lubricating grease enters the housing 1 through the oil inlet 7 to reduce the friction when the rotating blade 3 rotates, and can be discharged with the condensate.

[0025] In this embodiment, the condenser uses a volume compression method to increase the pressure of iodine vapor in the vacuum pipeline. This allows iodine to be pressurized before entering the vacuum pump, achieving efficient low-temperature, high-pressure condensation. The iodine is then captured and collected by the condenser, greatly improving the iodine recovery efficiency and effectively protecting the vacuum pump system.

[0026] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
