Description

Technical Field

[0001] The utility model belongs to the technical field of adsorption tanks of oxygen generators, and more specifically, particularly relates to a highly sealed aluminum alloy adsorption tank for an oxygen generator. Background Technique

[0002] The adsorption tank of an oxygen generator is a key component in the oxygen generator, also known as an oxygen adsorbent tank or adsorbent column. It is generally an aluminum alloy tank body with an adsorption sieve cylinder inside. Its function is to adsorb non-oxygen components such as nitrogen in the air, so as to provide a pure oxygen supply.

[0003] For the existing adsorption tanks of oxygen generators, the adsorption sieve cylinder is generally pressed and installed by a threaded drive of a contact plate. After the adsorption sieve cylinder is pressed, it can squeeze the sealing gasket to seal the pipeline connection part between the adsorption sieve cylinder and the adsorption tank. This connection method cannot control the pressing force of the contact plate on the adsorption sieve cylinder. If the pressing force is too large, it is easy to cause excessive deformation and damage of the sealing gasket. If the pressing force is too small, the sealing gasket cannot play a sealing role, both of which will lead to the phenomenon of poor internal sealing performance of the adsorption tank, with poor stability and low practicality.

[0023] As shown in the attached Figure 1 to the attached Figure 6 figure:

[0024] Embodiment 1: The present utility model provides a highly sealed oxygen generator aluminum alloy adsorption tank, which includes an adsorption assembly 1. The adsorption assembly 1 includes a tank body 101, an adsorption cylinder 102 and a connecting gasket 103. The adsorption cylinder 102 is inserted into the interior of the tank body 101, and the connecting gasket 103 is arranged at the channel connection part between the adsorption cylinder 102 and the tank body 101. An intake pipe 1011 and an exhaust pipe 1012 are respectively arranged on the side and bottom of the tank body 101, and the exhaust pipe 1012 is communicated with the inner cavity of the adsorption cylinder 102; an installation assembly 2. The installation assembly 2 includes a contact pressure plate 201, an operation rotary block 202 and a limit seat 203. The bottom of the contact pressure plate 201 abuts against the top of the adsorption cylinder 102, and the contact pressure plate 201 is inserted into the interior of the tank body 101. The operation rotary block 202 is rotatably connected to the interior of the contact pressure plate 201, and the limit seat 203 is radially inserted into the interior of the operation rotary block 202

[0025] In the embodiment of the present disclosure, the side surface of the contact pressure plate 201 is provided with threads, and the contact pressure plate 201 is screwed onto the top of the tank body 101 through the threads. During use, the installation and disassembly operations of the adsorption cylinder 102 can be realized through the installation assembly 2. When it is necessary to install the adsorption cylinder 102, insert the adsorption cylinder 102 into the interior of the tank body 101 and align the internal channels of the adsorption cylinder 102 and the tank body 101. At this time, both sides of the connecting gasket 103 will be respectively squeezed by the adsorption cylinder 102 and the tank body 101. Then, screw the contact pressure plate 201 into the top of the tank body 101 through the threads and press the adsorption cylinder 102 tightly, and the installation operation can be completed. When it is necessary to disassemble the adsorption cylinder 102, just unscrew the contact pressure plate 201 from the interior of the tank body 101 and then disassemble the adsorption cylinder 102. The installation and disassembly are convenient and flexible

[0026] In the embodiment of the present disclosure, a transmission top spring 2031 is provided on the top of the limit seat 203, and the two ends of the transmission top spring 2031 respectively abut against the inside of the limit seat 203 and the inside of the operating rotary block 202, a rotation control groove is provided on the side of the operating rotary block 202, and a rotation control protrusion 2021 is provided inside the operating rotary block 202, and the rotation control protrusion 2021 is plugged into the inside of the rotation control groove, and the rotation control groove is composed of a spiral driving groove 2032 and a circular avoidance groove 2033, and the bottom of the driving groove 2032 is connected to the groove body of the avoidance groove 2033, and the upward rotation direction of the driving groove 2032 is opposite to the tightening direction of the contact pressure plate 201. In the embodiment, the mounting assembly 2 has the function of limiting the clamping force. By operating the rotary block 202, the contact pressure plate 201 can be screwed in and out of the top of the tank body 101. When the contact pressure plate 201 needs to be screwed into the top of the tank body 101, the operating rotary block 202 can be rotated forward. At this time, under the action of the transmission top spring 2031, when the operating rotary block 202 rotates forward, the rotation control protrusion 2021 will press against the inside of the driving groove 2032 and drive the limit seat 203 to rotate forward. When the limit seat 203 rotates forward, the synchronous gear 2034 can drive the contact pressure plate 201 to rotate synchronously forward through the synchronous tooth groove 2011 to realize the screwing-in operation, which is easy to operate.

[0027] In the embodiment of the present disclosure, a synchronous gear 2034 is provided at the bottom of the limit seat 203, and a synchronous tooth groove 2011 is provided inside the contact pressure plate 201, and the synchronous gear 2034 is inserted into the inside of the synchronous tooth groove 2011. During use, as the contact pressure plate 201 is screwed into the depth, the clamping force exerted on the adsorption cylinder 102 will also increase, the deformation of the connecting sealing gasket 103 will also increase, and the rotational resistance of the contact pressure plate 201 will also increase. Until the rotational resistance of the contact pressure plate 201 is greater than the force of the transmission top spring 2031 on the limit seat 203, since the upward rotation direction of the driving groove 2032 is opposite to the tightening direction of the contact pressure plate 201, the rotation control protrusion 2021 will be poured into the inside of the avoidance groove 2033 by the driving groove 2032. In this process, the limit seat 203 will move up and compress the transmission top spring 2031. After the limit seat 203 moves up, the synchronous gear 2034 will fall out of the synchronous tooth groove The interior of 2011 makes it impossible for the contact pressure plate 201 to continue to be driven by the limit seat 203 and the operating rotary block 202 to rotate forward, thereby realizing the function of limiting the clamping force of the adsorption cylinder 102, ensuring that the connecting sealing gasket 103 is always in a stable deformation amount to seal the connection part of the adsorption cylinder 102 and the tank body 101 channel, and the sealing performance is extremely strong and stable. The operating rotary block 202 can always drive the contact pressure plate 201 to reverse and screw it out of the tank body 101 when reversing. No matter where the rotary control protrusion 2021 is located, when the operating rotary block 202 is reversed, the rotary control protrusion 2021 can always enter the interior of the driving groove 2032 under the action of the transmission top spring 2031, so that the synchronous gear 2034 is in a state of being inserted into the synchronous tooth groove 2011, so that the operating rotary block 202 can realize the operation of reversing and screwing the contact pressure plate 201 out of the tank body 101 when reversing, which is flexible and convenient to use.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In the present invention, the installation and removal operation of the adsorption cylinder 102 can be realized through the installation component 2. When the adsorption cylinder 102 needs to be installed, the adsorption cylinder 102 is inserted into the interior of the tank body 101 and the internal channels of the adsorption cylinder 102 and the tank body 101 are aligned. At this time, the two sides of the connecting sealing gasket 103 will be squeezed by the adsorption cylinder 102 and the tank body 101 respectively. Thereafter, the contact pressure plate 201 is screwed into the top of the tank body 101 through a thread and the adsorption cylinder 102 is pressed tightly to complete the installation operation. When the adsorption cylinder 102 needs to be removed, it is only necessary to unscrew the contact pressure plate 201 out of the interior of the tank body 101 and then remove the adsorption cylinder 102. The installation component 2 has the function of limiting the pressing force. By operating The rotary block 202 can realize the screwing in and screwing out operation of the resistance pressure plate 201 on the top of the tank body 101. When the resistance pressure plate 201 needs to be screwed into the top of the tank body 101, the rotary block 202 can be rotated forward. At this time, under the action of the transmission top spring 2031, when the operating rotary block 202 rotates forward, the rotation control protrusion 2021 will contact the inside of the driving groove 2032 and drive the limit seat 203 to rotate forward. When the limit seat 203 rotates forward, the synchronous gear 2034 can drive the resistance pressure plate 201 to rotate forward synchronously through the synchronous tooth groove 2011 to realize the screwing in operation. As the resistance pressure plate 201 is screwed into a deeper depth, the clamping force on the adsorption cylinder 102 will also increase, and the deformation of the connecting sealing gasket 103 will be increased. The rotational resistance of the contact pressure plate 201 will also become larger, and the rotational resistance of the contact pressure plate 201 will also become larger, until the rotational resistance of the contact pressure plate 201 is greater than the force of the transmission top spring 2031 on the limit seat 203. Since the upward rotation direction of the driving groove 2032 is opposite to the tightening direction of the contact pressure plate 201, the rotation control protrusion 2021 will be poured into the inside of the avoidance groove 2033 by the driving groove 2032. In this process, the limit seat 203 will move up and compress the transmission top spring 2031. After the limit seat 203 moves up, the synchronous gear 2034 will disengage from the inside of the synchronous tooth groove 2011, and then the contact pressure plate 201 can no longer be driven by the limit seat 203 and the operating rotary block 202 to continue to rotate forward, thereby achieving the limit of the clamping force of the adsorption cylinder 102. The function of the position ensures that the connecting sealing gasket 103 is always in a stable deformation amount, and the connection part of the sealing adsorption cylinder 102 and the channel of the tank body 101 has extremely strong and stable sealing performance. The operating rotary block 202 can always drive the resistance pressure plate 201 to reverse and screw it out of the tank body 101 when it is reversed. No matter where the rotary control protrusion 2021 is located, when the operating rotary block 202 is reversed, the rotary control protrusion 2021 can always enter the interior of the driving groove 2032 under the action of the transmission top spring 2031, so that the synchronous gear 2034 is in a state of being inserted into the interior of the synchronous tooth groove 2011, thereby realizing the operation of the resistance pressure plate 201 to reverse and screw it out of the tank body 101 when the operating rotary block 202 is reversed.
