Description

Technical Field

[0001] This utility model relates to the field of high-purity oxygen preparation technology, specifically to a high-purity oxygen preparation apparatus. Background Technology

[0002] High-purity oxygen is a colorless, tasteless, and odorless gas that is slightly soluble in water. Chemically, it has strong oxidizing properties and can react with many substances in an oxidation reaction.

[0003] In practical use, existing high-purity oxygen preparation devices require an air compressor to compress air. However, a filter membrane is installed at the air compressor's inlet. This filter membrane needs to be replaced after prolonged use, but the replacement method is quite cumbersome. In addition, there is a risk of leakage at the pipe connections after prolonged use, and it is impossible to check for leakage in time, which can lead to oxygen leakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-purity oxygen preparation apparatus that features easy filter membrane replacement and leakage alarm, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a high-purity oxygen preparation device, including an air compressor. A molecular sieve separation device and an absorption tube are fixedly installed on the outer wall of the air compressor. A drying chamber is fixedly installed on the outer wall of the molecular sieve separation device. One end of a connecting pipe is fixedly installed on the outer wall of the drying chamber, and a storage tank is fixedly installed on the other end of the connecting pipe. An installation shell is fixedly installed on the outer wall of the absorption tube. An installation plate is slidably connected to the inner wall of the installation shell. A filter membrane is fixedly assembled on the inner wall of the installation plate. A fixing block is fixedly installed at the bottom of the installation plate. A locking pin is slidably connected to the inner wall of the installation shell. A spring is provided on the inner wall of the installation shell, and a pull rod is fixedly installed on the outer wall of the locking pin. At one end of the pull rod, a horizontal plate is fixedly installed at the other end. A warning light is fixedly installed on the top of the drying oven. A fixed shell is fixedly installed on the outer wall of the drying oven. A sealing plate is provided on the outer wall of the fixed shell. A fixing bolt is slidably connected to the inner wall of the sealing plate. A first airtight ring and a second airtight ring are fixedly installed on the side of the sealing plate near the fixed shell. An extension shell is fixedly installed on the top of the fixed shell. A pressure sensor is fixedly installed on the top of the extension shell. A push plate is slidably connected to the inner wall of the extension shell. A limit block is fixedly installed on the outer wall of the push plate. A second spring is provided on the inner wall of the extension shell. A second spring is fixedly installed on the top of the push plate. A limit rod is fixedly installed on the inner wall of the extension shell.

[0006] As a preferred technical solution of this utility model: the outer wall of the mounting plate is the same size as the inner wall of the mounting shell, and the fixing block penetrates the bottom of the mounting shell.

[0007] As a preferred technical solution of this utility model: the height of the fixing block is the same as the height of the locking pin, and the inner wall of the fixing block is adapted to the shape of the locking pin.

[0008] As a preferred technical solution of this utility model: there are two second airtight rings, and the two second airtight rings are respectively located on the outer wall of the sealing plate and the inner wall of the fixing shell. The two second airtight rings are located on the outer wall of the connecting pipe, and the two second airtight rings are in contact with the outer wall of the connecting pipe.

[0009] As a preferred technical solution of this utility model: there are two limiting rods and two limiting blocks, and the two limiting rods and two limiting blocks are symmetrically arranged, with the two limiting rods passing through the two limiting blocks.

[0010] As a preferred technical solution of this utility model: the probe of the pressure sensor penetrates through the top of the extension shell, and the probe of the pressure sensor is located at the top of the pressure rod, and the pressure sensor is electrically connected to the warning light.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This high-purity oxygen preparation device, by pulling the horizontal plate, causes the horizontal plate to move the pull rod, which in turn moves the locking pin, causing the spring to contract. At this time, the locking pin moves to the inner wall of the mounting shell, thus separating the locking pin from the inner wall of the fixing block. At this time, the fixing relationship of the fixing block disappears, and the fixing block can be moved. Then, by pulling the mounting plate upward, the mounting plate causes the filter membrane and the fixing block to separate from the inner wall of the mounting shell, so that the filter membrane can be removed and replaced.

[0013] 2. In this high-purity oxygen preparation device, when there is a leak at the connection point of the connecting pipe, gas will leak between the fixed shell and the sealing plate. At this time, the gas pressure in the fixed shell and the sealing plate will increase, which will cause the push plate to move upward under pressure. The push plate will drive the pressure rod to move upward, which will cause the pressure rod to come into contact with the probe of the pressure sensor. At this time, the pressure sensor will be triggered, which will send a signal to the warning light, causing the warning light to flash, thus alerting the operator that there is a leak in the connecting pipe.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 6The apparatus for preparing high-purity oxygen includes an air compressor 1. A molecular sieve separation device 2 and an absorption tube 6 are fixedly installed on the outer wall of the air compressor 1. A drying oven 3 is fixedly installed on the outer wall of the molecular sieve separation device 2. One end of a connecting pipe 5 is fixedly installed on the outer wall of the drying oven 3, and a storage tank 4 is fixedly installed on the other end of the connecting pipe 5. An installation shell 7 is fixedly installed on the outer wall of the absorption tube 6. An installation plate 8 is slidably connected to the inner wall of the installation shell 7. A filter membrane 9 is fixedly assembled on the inner wall of the installation plate 8. A fixing block 10 is fixedly installed at the bottom of the installation plate 8. A locking pin 11 is slidably connected to the inner wall of the installation shell 7. A spring 12 is provided on the inner wall of the installation shell 7. One end of a pull rod 13 is fixedly installed on the outer wall of the locking pin 11, and a horizontal bar is fixedly installed on the other end of the pull rod 13. A warning light 15 is fixedly installed on the top of the drying oven 3. A fixed shell 16 is fixedly installed on the outer wall of the drying oven 3. A sealing plate 17 is provided on the outer wall of the fixed shell 16. A fixing bolt 18 is slidably connected to the inner wall of the sealing plate 17. A first airtight ring 19 and a second airtight ring 20 are fixedly installed on the side of the sealing plate 17 near the fixed shell 16. An extension shell 21 is fixedly installed on the top of the fixed shell 16. A pressure sensor 22 is fixedly installed on the top of the extension shell 21. A push plate 23 is slidably connected to the inner wall of the extension shell 21. A limit block 27 is fixedly installed on the outer wall of the push plate 23. A second spring 25 is provided on the inner wall of the extension shell 21. A second spring 25 is fixedly installed on the top of the push plate 23. A limit rod 26 is fixedly installed on the inner wall of the extension shell 21.

[0023] In the above structure, the fixing bolt 18 is inserted from the outer wall of the sealing plate 17 to the inner wall of the fixing shell 16, and the fixing bolt 18 is rotated to fix the fixing shell 16 and the sealing plate 17.

[0024] In a preferred embodiment: the outer wall of the mounting plate 8 is the same size as the inner wall of the mounting shell 7, and the fixing block 10 penetrates the bottom of the mounting shell 7.

[0025] In the above structure, by inserting the mounting plate 8 into the inner wall of the mounting shell 7, the fixing block 10 enters the inner wall of the mounting shell 7, the mounting plate 8 is moved to the bottom of the inner wall of the mounting shell 7, and the fixing block 10 reaches the bottom of the mounting shell 7.

[0026] In a preferred embodiment, the height of the fixing block 10 is the same as the height of the locking pin 11, and the inner wall of the fixing block 10 is adapted to the shape of the locking pin 11.

[0027] In the above structure, when the fixing block 10 reaches the outside of the locking pin 11, the spring 12 pushes the locking pin 11 toward the fixing block 10, thereby causing the locking pin 11 to enter the inner wall of the fixing block 10, fixing the position of the inner wall of the fixing block 10, thereby fixing the position of the fixing block 10, and fixing the upper mounting plate 8 to the inner wall of the mounting shell 7.

[0028] In a preferred embodiment: there are two second airtight rings 20, and the two second airtight rings 20 are respectively located on the outer wall of the sealing plate 17 and the inner wall of the fixing shell 16. The two second airtight rings 20 are located on the outer wall of the connecting pipe 5, and the two second airtight rings 20 are in contact with the outer wall of the connecting pipe 5.

[0029] In the above structure, the contact surfaces of the connecting pipe 5 with the sealing plate 17 and the fixed shell 16 are sealed by two second airtight rings 20, thereby forming a sealed space between the fixed shell 16 and the sealing plate 17. When the connecting pipe 5 leaks, the gas leaking from the connecting pipe 5 leaks between the fixed shell 16 and the sealing plate 17, thereby increasing the air pressure between the fixed shell 16 and the sealing plate 17, causing the push plate 23 to move upward under pressure.

[0030] In a preferred embodiment, there are two limiting rods 26 and two limiting blocks 27, and the two limiting rods 26 and the two limiting blocks 27 are symmetrically arranged, with the two limiting rods 26 passing through the two limiting blocks 27.

[0031] In the above structure, the two limiting rods 26 limit the two limiting blocks 27, so that the two limiting blocks 27 will not tilt when moving, and thus the push plate 23 will not tilt when moving.

[0032] In a preferred embodiment: the probe of pressure sensor 22 penetrates the top of extension housing 21, and the probe of pressure sensor 22 is located on top of pressure rod 24, and pressure sensor 22 is electrically connected to warning light 15.

[0033] In the above structure, the upward movement of the push plate 23 drives the pressure rod 24 to move upward, thereby causing the top of the pressure rod 24 to come into contact with the probe of the pressure sensor 22, thus causing the probe of the pressure sensor 22 to be pressed. At this time, the pressure sensor 22 sends an electrical signal to the warning light 15, thereby causing the warning light 15 to flash.

[0034] Working Principle: When using this equipment, the air compressor 1 is started. The air compressor 1 draws in air through the absorption pipe 6 and compresses it to form compressed air. The air compressor 1 transmits the compressed air to the molecular sieve separation device 2, where it separates and purifies the compressed air, separating substances other than oxygen to form pure oxygen. The molecular sieve separation device 2 transmits the pure oxygen to the drying chamber 3 for drying. The dried pure oxygen is then transmitted to the storage tank 4 through the connecting pipe 5 for storage. When the filter membrane 9 needs to be replaced, the horizontal plate 14 is pulled, which in turn moves the pull rod 13. The pull rod 13 moves the locking pin 11, causing the spring 12 to contract. At this time, the locking pin 11 enters the mounting shell 7, thus establishing the connection between the locking pin 11 and the fixing block 10. When the filter membrane 9 and the fixing block 10 are moved upwards, the mounting plate 8 disappears. At this time, the mounting plate 8 moves upwards, causing the mounting plate 8, the filter membrane 9, and the fixing block 10 to move out from the inner wall of the mounting shell 7, so that the filter membrane 9 can be replaced. After replacement, the structure can be reset for use. When a leak occurs at the connection of the connecting pipe 5, the leaking gas from the connecting pipe 5 leaks between the fixing shell 16 and the sealing plate 17, thereby increasing the air pressure between the fixing shell 16 and the sealing plate 17. This causes the push plate 23 to be pressed upwards, which in turn causes the push plate 23 to move the pressure rod 24 upwards. This causes the top of the pressure rod 24 to come into contact with the probe of the pressure sensor 22, thereby pressing the probe of the pressure sensor 22. At this time, the pressure sensor 22 sends an electrical signal to the warning light 15, causing the warning light 15 to flash. The flashing of the warning light 15 alerts the staff that there is a leak in the connecting pipe 5.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
