Description

Technical Field

[0001] This utility model relates to the field of oxygen supply technology, and discloses an electric-free oxygen supply machine for civil defense projects. Background Technology

[0002] A non-electric oxygen supply system is a device that adds oxygen to water without requiring electricity. This type of device is particularly useful in locations where a stable power supply is unavailable. In civil defense projects, non-electric oxygen supply systems are primarily used to ensure the breathing needs of personnel in underground spaces during power outages or other emergencies. The design of these devices must overcome the challenges of the lack of electrical support to ensure a continued supply of necessary oxygen in emergencies.

[0003] Chemical oxygen generators are a common type of non-electric oxygen supply equipment used in civil defense projects. They generate oxygen through chemical reactions produced by specific chemical substances. However, while these generators are small in size, the amount of oxygen they produce is limited, making continuous oxygen production difficult. They may also generate heat and byproducts. To address this, manual operation, such as using a hand-cranked pump, is employed to force fresh outside air into the enclosed space. Then, molecular sieves adsorb nitrogen and other gaseous components, thus achieving a prolonged oxygenation effect.

[0004] Therefore, there is a need for an electric oxygen supply machine that can continuously produce oxygen for use in civil defense projects. Utility Model Content

[0005] In order to overcome the shortcomings of existing technology, such as small size but limited oxygen production, difficulty in achieving continuous oxygen production, and potential generation of heat and byproducts, this utility model provides an electric-free oxygen supply machine for civil defense projects that can continuously produce oxygen.

[0006] This utility model provides the following technical solution: A non-electric oxygen supply machine for civil defense projects, comprising a support plate, a first adsorption tower, a hand-cranked pump, an air inlet pipe, a rocker arm, a first connecting pipe, a sealing ring, an air inlet valve, an oxygen outlet pipe, an air outlet valve, and an adsorbent bed. The first adsorption tower is placed on the support plate, and the hand-cranked pump is installed on the support plate. The air inlet pipe is connected to and communicates with the hand-cranked pump. A rocker arm is rotatably installed on the left side of the hand-cranked pump, and the first connecting pipe is connected to and communicates with the right side of the hand-cranked pump. One end of the first connecting pipe is connected to the bottom of the first adsorption tower. A sealing ring is provided, which contacts the hand-cranked pump. An air inlet valve is provided on the first connecting pipe. An oxygen outlet pipe is connected and communicated to the top of the first adsorption tower, and an air outlet valve is provided on the oxygen outlet pipe. An adsorbent bed is provided inside the first adsorption tower. It also includes a second adsorption tower and a second connecting pipe. The second adsorption tower is placed on the support plate. The second adsorption tower is also provided with an oxygen outlet pipe and an adsorbent bed. The second connecting pipe is connected and communicated to the first connecting pipe. One end of the second connecting pipe is connected to the bottom of the second adsorption tower. An air inlet valve is also provided on the second connecting pipe.

[0007] As a further preferred embodiment, it also includes a guide frame, a fixed frame, a limiting frame, a connecting plate, and a pull rod. The guide frame is fixedly connected to both the front and rear sides of the bearing plate. The fixed frame is provided on the rocker arm. The limiting frame is slidably provided on both the front and rear sides of the fixed frame. Two pull rods are fixedly connected to each limiting frame. The connecting plate is slidably provided on the guide frame, and the pull rod passes through the connecting plate.

[0008] As a further preferred embodiment, it also includes a filter box, a filter, a cover plate, a pull rod, and a fixing pipe. The filter box is fixedly connected to the support plate, the filter box contains a filter, the top of the filter box is covered with a cover plate, two pull rods are fixedly connected to the cover plate, and the right side of the filter box is connected to and communicates with the fixing pipe, which is connected to the air intake pipe.

[0009] As a further preferred option, comfort cotton is also included, with comfort cotton provided on the joystick.

[0010] As a further preferred option, a silicone sleeve is also included, with each pull rod fitted with a silicone sleeve.

[0011] As a further preferred option, an anti-slip sleeve is also included, with the pull rod fitted with an anti-slip sleeve.

[0012] Compared with the prior art, this utility model provides an electric-free oxygen supply machine for civil defense projects, which has the following beneficial effects: 1. By rotating the air inlet valve on the first connecting pipe, air is prevented from entering the first adsorption tower. Then, by rotating the air inlet valve on the second connecting pipe, air is allowed to enter the second adsorption tower through the second connecting pipe, thereby achieving the purpose of continuous oxygen production and improving the efficiency of oxygen production.

[0013] 2. By having multiple people simultaneously hold the pull rod and move it back and forth, the connecting plate and the limiting frame move accordingly. The movement of the limiting frame causes the fixed frame to rotate the rocker arm up and down, thus enabling multiple people to work together and making the operation more efficient.

[0014] 3. Air is drawn in through the filter and filtered to remove impurities, thus preventing impurities from clogging the intake pipe. The filtered air is then delivered to the intake pipe through a fixed pipe. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Example 1: A non-electric oxygen supply machine for civil defense projects. Please refer to [link / reference]. Figures 1-7 The system includes a support plate 1, a first adsorption tower 2, a hand-cranked pump 4, an inlet pipe 5, a rocker arm 6, a first connecting pipe 7, a sealing ring 8, an inlet valve 9, an oxygen outlet pipe 11, an outlet valve 12, and an adsorbent bed 13. The first adsorption tower 2 is placed on the support plate 1. The hand-cranked pump 4 is bolted to the support plate 1. The inlet pipe 5 is connected to and connected to the hand-cranked pump 4. A rocker arm 6 is rotatably mounted on the left side of the hand-cranked pump 4, and a first connecting pipe 7 is connected to and connected to the right side of the hand-cranked pump 4. One end of the first connecting pipe 7 is connected to the bottom of the first adsorption tower 2, and a sealing ring 8 is mounted on one end of the first connecting pipe 7. The sealing ring 8 contacts the hand-cranked pump 4. An air inlet valve 9 is provided on the first adsorption tower 2. An oxygen outlet pipe 11 is connected to and communicates with the top of the first adsorption tower 2. An air outlet valve 12 is provided on the oxygen outlet pipe 11. An adsorbent bed 13 is provided inside the first adsorption tower 2. A second adsorption tower 3 is placed on the support plate 1. An oxygen outlet pipe 11 and an adsorbent bed 13 are also provided on the second adsorption tower 3. A second connecting pipe 10 is connected to and communicates with the first connecting pipe 7. One end of the second connecting pipe 10 is connected to the bottom of the second adsorption tower 3. An air inlet valve 9 is also provided on the second connecting pipe 10. Comfort cotton 24 is provided on the rocker arm 6 to increase hand comfort and avoid hand redness and swelling caused by turning the rocker arm 6 for a long time.

[0025] When the non-electric oxygen supply machine is needed, first hold the crank 6 and turn it downwards, then turn the crank 6 upwards. Repeating the above operation will draw outside air into the hand pump 4 through the air inlet pipe 5, compress it through the hand pump 4, and deliver it into the first connecting pipe 7. After the air enters the first connecting pipe 7, it enters the first adsorption tower 2 through the first connecting pipe 7, where the adsorbent bed 13 adsorbs nitrogen and other gaseous components, allowing oxygen to pass through, thereby achieving the purpose of oxygen production. When oxygen is needed, turn the outlet valve 12 to discharge oxygen through the oxygen outlet pipe 11. When the adsorbent bed 13 in the first adsorption tower 2 is saturated, turn the inlet valve 9 on the first connecting pipe 7 to prevent air from entering the first adsorption tower 2. Then turn the inlet valve 9 on the second connecting pipe 10 to allow air to enter the second adsorption tower 3 through the second connecting pipe 10, thereby achieving the purpose of continuous oxygen production and improving the efficiency of oxygen production. At the same time, the adsorbent is heated to accelerate the nitrogen desorption process, and the desorbed nitrogen is discharged into the air outside the civil defense project, thus completing the regeneration cycle.

[0026] Example 2: Based on Example 1, please refer to... Figure 6 The bearing plate 1 is fixedly connected to the front and rear sides of the guide frame 1. The rocker arm 6 is provided with a fixed frame 15. The fixed frame 15 is slidably provided with limit frames 16 on the front and rear sides. Two pull rods 18 are fixedly connected to each limit frame 16. The guide frame 14 is slidably provided with a connecting plate 17. The pull rods 18 pass through the connecting plate 17. Each pull rod 18 is fitted with a silicone sleeve 25. The silicone sleeve 25 is relatively soft and can reduce the pressure between the pull rod 18 and the hand.

[0027] When it is necessary to rotate the rocker arm 6, two or four workers simultaneously hold the pull rod 18 and move the pull rod 18 back and forth, causing the connecting plate 17 and the limiting frame 16 to move accordingly. The movement of the limiting frame 16 causes the fixed frame 15 to rotate the rocker arm 6 up and down, thereby enabling multi-person collaboration and allowing multiple workers to apply force at the same time, thus making the operation more efficient.

[0028] Please see Figure 1 and Figure 7 A filter box 19 is fixedly connected to the support plate 1. A filter 20 is installed inside the filter box 19. The top of the filter box 19 is covered with a cover plate 21. When it is necessary to clean the filter 20, the filter box 19 can be opened by pulling the cover plate 21 upward. Two pull rods 22 are fixedly connected to the cover plate 21. A fixed pipe 23 is connected and communicated to the right side of the filter box 19. The fixed pipe 23 is communicated with the air inlet pipe 5. An anti-slip sleeve 26 is fitted on the pull rod 22. The anti-slip sleeve 26 increases the friction between the hand and the pull rod 22 to prevent the hand from slipping when pulling the cover plate 21 upward.

[0029] When using the non-electric oxygen supply machine, the gas is drawn into the filter box 19 by the hand pump 4. The air passes through the filter 20, which filters the air and removes impurities, thereby preventing impurities from clogging the air inlet pipe 5. The filtered air is then delivered to the air inlet pipe 5 through the fixed pipe 23.

[0030] 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.
