Description

Technical Field

[0001] This utility model relates to the technical field of liquid oxygen preparation devices, and in particular to a liquid oxygen preparation condensation and evaporation device. Background Technology

[0002] Liquid oxygen is the liquid state of oxygen. It has important applications in aerospace, submarines, and the gas industry. Liquid oxygen is a light blue liquid. The preparation process of liquid oxygen mainly includes the following steps: compressed air, condensation, steam cooling, diffusion, and finally adsorption to remove other impurities to obtain high-concentration oxygen. The high-concentration oxygen is then heated to decompose it into oxygen molecules, which are then cooled to obtain high-purity liquid oxygen. Different processing steps require different processing equipment during the preparation process.

[0003] Announcement No. CN222877647U proposes a liquid oxygen preparation condensation and evaporation device. This device consists of a water collection plate, an outer frame, a baffle plate, and water-resistant bristles. When a fan is activated, air is discharged to the outside, while outside air continuously enters the chamber through louvers. During the air discharge process, water vapor passes through the water collection plate and, through the baffle plate within the plate, comes into contact with the flowing air and adheres to it, achieving a water vapor barrier effect. The water-resistant bristles further enhance the water vapor barrier effect without affecting the normal air discharge.

[0004] However, during the implementation of this device, the fan and louvers are used to draw air from inside the equipment, while outside air enters through the louvers to replace the air. However, due to the presence of dust particles in the air, and the fact that the device cools the equipment by atomizing water into a mist, the dust particles in the air entering the equipment come into contact with and mix with the sprayed water mist. Furthermore, the water is recycled, which leads to the clogging of the spray nozzles due to the dust particles mixed in the water over long-term use, affecting the subsequent use of the device. To address this issue, a liquid oxygen preparation condensation and evaporation device is proposed. Utility Model Content

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please see Figures 1-6 As shown, a liquid oxygen preparation condensation and evaporation device includes an outer shell 1, a fixed shell 4 fixedly connected inside the outer shell 1, a sliding frame 5 slidably connected inside the fixed shell 4, the sliding frame 5 and the fixed shell 4 being fixed together by bolts, a handle 7 fixedly connected to the surface of the sliding frame 5, a filter screen 8 disposed inside the sliding frame 5 for filtering water entering the water pump 2, a threaded sleeve 11 fixedly connected inside the sliding frame 5, a threaded rod 6 in contact inside the sliding frame 5, the threaded rod 6 penetrating into the interior of the sliding frame 5, the surface of the threaded rod 6 being threadedly connected to the interior of the threaded sleeve 11, a sliding rod 13 rotatably connected to the surface of the threaded rod 6 inside the sliding frame 5, and the sliding rod 13 being slidably connected to the interior of the sliding frame 5, a rack 14 fixedly connected to the surface of the sliding rod 13, a cover plate 10 rotatably connected to the interior of the sliding frame 5, a gear 15 fixedly connected to the surface of the mounting shaft of the cover plate 10, and the surface of the gear 15 meshing with the surface of the rack 14.

[0025] A spray plate 3 is fixedly connected inside the equipment casing 1. A water spray nozzle is provided at the lower end of the spray plate 3. A water pump 2 is fixedly connected to the surface of the equipment casing 1. The output end of the water pump 2 is connected to the spray plate 3, and the input end of the water pump 2 extends into the interior of the equipment casing 1. The fixed shell 4 is fixedly connected to the water pump 2. The water pump 2 draws cooling water from inside the equipment casing 1, allowing the water to enter the interior of the spray plate 3 and spray it onto the condenser tubes to cool them down. Therefore, its operation will not be explained further.

[0026] A movable rod 12 is slidably connected inside the sliding frame 5. The movable rod 12 passes through both sides of the sliding frame 5, and both ends of the movable rod 12 are trapezoidal. A limiting groove 17 is opened inside the filter screen 8. The inner wall of the limiting groove 17 is slidably connected to the surface of the movable rod 12. The end of the movable rod 12 inside the limiting groove 17 is trapezoidally vertical, and the end of the movable rod 12 outside the sliding frame 5 is trapezoidally horizontal. A return spring 16 is movably sleeved on the surface of the movable rod 12. The two ends of the return spring 16 are fixedly connected to the movable rod 12 and the sliding frame 5, respectively. The position of the movable rod 12 is controlled by the return spring 16. When the sliding frame 5 is inside the fixed shell 4, the return spring 16 is in a compressed state.

[0027] A rubber pad 9 is fixedly connected to the surface of the sliding frame 5. The surface of the rubber pad 9 is in contact with the inside of the fixed shell 4. The rubber pad 9 fills the gap between the fixed shell 4 and the sliding frame 5, thereby reducing the possibility of leakage.

[0028] Working principle: When installing and using the filter screen 8, the sliding bracket 5 is inserted into the fixed housing 4. Then, the threaded rod 6 is rotated, and with the setting of the threaded sleeve 11, the threaded rod 6 slides into the threaded sleeve 11 as it rotates. The threaded rod 6 drives the sliding rod 13 to slide, and the sliding rod 13 is slidably connected to the inside of the sliding bracket 5. This causes the sliding rod 13 to drive the rack 14 to move. The rack 14 slides and drives the gear 15. The gear 15 then drives the cover plate 10 and its mounting shaft to flip. At this time, the cover plate 10 is in contact with the inner wall of the fixed housing 4 and no longer covers the filter screen 8, allowing the filter screen 8 to be used. When it is necessary to remove the sliding bracket 5, the threaded rod 6 is rotated again, and the threaded rod 6 drives the sliding rod 13 to move upward. The movement of the sliding rod 13 causes the rack 14, gear 15, and cover plate 10 to rotate and reset. The cover plate 10 rotates to cover the side of the filter screen 8 that is being filtered.

[0029] When the sliding frame 5 is inserted, the inner wall of the fixed shell 4 presses against the inclined surface of the moving rod 12, causing the moving rod 12 to slide under force. The sliding of the moving rod 12 compresses the return spring 16, causing the moving rod 12 to be inserted into the limiting groove 17, thereby locking the filter screen 8. When the sliding frame 5 is removed, the fixed shell 4 no longer obstructs the moving rod 12. Under the elastic force of the return spring 16, the moving rod 12 slides inside the limiting groove 17, and the inclined surface of the moving rod 12 inside the limiting groove 17 contacts it. When the filter screen 8 is separated from the sliding frame 5, the filter screen 8 is pressed, and the limiting groove 17 presses against the inclined surface of the moving rod 12 inside it. The moving rod 12 then slides into the sliding frame 5 and separates from the limiting groove 17, making it easier for the staff to disassemble the filter screen 8.

[0030] In actual use, the equipment is placed in a suitable position. After the air is compressed by the compressor to form high-pressure gas, the gas is introduced into the condenser coil through the air inlet. During this process, the water pump 2 is started to draw water from the bottom of the equipment casing 1 and introduce it into the spray plate 3. During this process, the filter screen 8 filters the water entering the water pump 2, and then sprays it downwards evenly through the nozzles at the bottom of the spray plate 3. The sprayed water will fall to the bottom of the equipment casing 1. During this process, the sprayed water mist contacts the outside of the condenser coil and cools the medium flowing through the condenser coil. Meanwhile, the fan starts to exhaust the air. At the same time, outside air continuously enters the equipment casing 1 through the louvers. During the air exhaust process, water vapor passes through the water collection plate and the baffle plate in the water collection plate, which contacts the flowing air and attaches to the water vapor, achieving the effect of blocking water vapor. The water-resistant baffle further enhances the water vapor blocking effect in the air without affecting the normal exhaust of the air. After the high-pressure air is condensed, it is finally discharged from the liquid outlet and enters the next processing step. This has been described in detail in the comparative document, so it will not be discussed in detail here.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
