Description

Technical Field

[0001] This utility model relates to the field of oxygen generation equipment technology, and in particular to a skid-mounted oxygen generator. Background Technology

[0002] In many fields such as medical emergency, industrial smelting, and high-altitude operations, there is an urgent need for a stable supply of oxygen. Skid-mounted oxygen generators, with their integrated, easy-to-transport, and rapid-deployment features, have become important equipment to meet these needs. As a key upstream component of skid-mounted oxygen generators, the air filtration system directly affects the overall performance and service life of the oxygen generator.

[0003] In existing skid-mounted oxygen concentrator air filtration systems, filter plates are mostly cleaned manually on a regular basis. This not only consumes a lot of manpower and time, but also makes it difficult to accurately determine the cleaning time when the equipment is running continuously. Once too much dust accumulates on the filter plates, the airflow resistance increases significantly, and the oxygen production efficiency will decrease drastically. At the same time, dust may enter downstream equipment, causing accelerated wear on core components such as compressors and adsorption towers, shortening the overall service life of the equipment. In addition, traditional filter plates are often fixed by complex structures such as bolt connections, making the disassembly process cumbersome, increasing maintenance difficulty and downtime, and failing to meet the requirements of continuous industrial production and rapid maintenance of oxygen concentrators in medical emergency scenarios.

[0004] Therefore, those skilled in the art have provided a skid-mounted oxygen generator to solve the problems mentioned in the background section. Utility Model Content

The cleaning mechanism includes a mounting plate. One side of the mounting plate is fixedly connected to the filter box. A motor is fixedly connected to the top side of the mounting plate. A sector gear is fixedly connected to the output end of the motor. The other side of the sector gear is movably connected to the filter box via a bearing. A toothed plate meshes with the top of the sector gear. A movable frame is fixedly connected to one side of the toothed plate. One side of the movable frame is slidably connected to the filter box.

A first spring is provided on the surface of the fixed rod. One side of the first spring is fixedly connected to the filter box. A brush is fixedly connected to the bottom of the movable frame.

[0007] Optionally, the locking mechanism includes a locking block located on one side of the filter box.

A stop block is slidably connected to one side of the inner cavity of the housing. A second spring is provided on one side of the stop block, and the other side of the second spring is fixedly connected to the housing. A pull rod is provided on the top of the second spring, and one side of the pull rod is fixedly connected to the stop block. One side of the locking block is engaged with the stop block.

[0008] Optionally, an air outlet pipe is fixedly connected to the top of the filter box, and an air compressor is fixedly connected to the other end of the air outlet pipe. The bottom of the air compressor is fixedly connected to the base plate. A heat exchanger is fixedly connected to the other side of the air compressor via pipe fittings.

[0010] Optionally, a pull plate is slidably connected to the inner cavity of the filter box, and a connecting rod is fixedly connected to one side of the pull plate.

[0011] Optionally, a filter screen is provided at the bottom of the connecting rod, and both sides of the filter screen are slidably connected to the filter box.

[0013] Optionally, a slot is provided at the top of the housing, and one side of the abutment block is slidably connected to the slot. In summary, this utility model has the following beneficial effects:

[0014] 1. The cleaning mechanism of this utility model has toothed plates at the top and bottom of the sector gear, and connects the moving frame and the brush. When the sector gear rotates once, it can drive the toothed plates at the top and bottom to move back and forth at the same time, so as to achieve synchronous cleaning of the surfaces of the two filter plates in the filter box. Compared with the traditional single-direction cleaning method, this structure greatly improves the cleaning efficiency, avoids the problem of serious local dust accumulation on the filter plates due to cleaning dead corners, ensures that the cleanliness of all parts of the filter plates is consistent, and effectively maintains the efficient operation of the air filtration system. When the sector gear rotates and disengages from the toothed plates, the toothed plates quickly return to their original position under the action of the first spring, preparing for the next cleaning cycle.

[0015] 2. The locking mechanism of this utility model fixes the filter plate by locking the locking block and the abutment block. During installation, the locking block is slid into the housing and pushed until the abutment block automatically locks in place under the action of the second spring, thus fixing the filter plate. This structural design avoids the complex methods of traditional bolt connections, significantly shortens the filter plate disassembly and assembly time, and improves maintenance efficiency. Moreover, the locking structure of the locking block and the abutment block provides a continuous and stable clamping force under the action of the second spring, ensuring that the filter plate will not loosen due to vibration or airflow impact during the operation of the oxygen generator, thus ensuring the sealing and stability of the air filtration system, preventing unfiltered air from bypassing into the subsequent system, and ensuring the oxygen production quality of the oxygen generator.

Compared with the single-side cleaning method, the cleaning blind spots are completely eliminated, and the surface of the filter plate 10 is fully covered. Each of the two movable frames 305 is fixedly connected to a partition on one side, and the two partitions are staggered to prevent the air inside the filter box 2 from leaking through the gaps when the movable frames 305 move. The staggered arrangement can also prevent the two movable frames 305 from colliding when they move.

[0027] Example 2:

[0028] Reference Figure 1-5The engaging mechanism 4 includes a locking block 401, which is located on one side of the filter box 2. A housing 402 is slidably connected to one side of the locking block 401, and one side of the housing 402 is fixedly connected to the filter box 2. A stop block 403 is slidably connected to one side of the inner cavity of the housing 402. A second spring 404 is provided on one side of the stop block 403, and the other side of the second spring 404 is fixedly connected to the housing 402. A pull rod 405 is provided on the top of the second spring 404, and one side of the pull rod 405 is fixedly connected to the stop block 403. One side of the locking block 401 is engaged with the stop block 403. An air outlet pipe 5 is fixedly connected to the top of the filter box 2, and an air compressor 6 is fixedly connected to the other end of the air outlet pipe 5. The bottom of the air compressor 6 is fixedly connected to the base plate 1, and a heat exchanger 7 is fixedly connected to the other side of the air compressor 6 via a pipe fitting. The bottom of heat exchanger 7 is fixedly connected to the base plate 1. On the other side of heat exchanger 7, an adsorption tower 8 is fixedly connected to the base plate 1. On the other side of adsorption tower 8, an oxygen buffer tank 9 is fixedly connected to the base plate 1. The bottom of oxygen buffer tank 9 is fixedly connected to the base plate 1. A filter plate 10 is slidably connected to the inner cavity of filter box 2. One side of filter plate 10 is fixedly connected to the locking block 401. A pull plate 11 is slidably connected to the inner cavity of filter box 2. A connecting rod 12 is fixedly connected to one side of pull plate 11. A filter screen 13 is provided at the bottom of connecting rod 12. Both sides of filter screen 13 are slidably connected to filter box 2. An air inlet pipe 14 is provided at the bottom of filter screen 13. The top of air inlet pipe 14 is fixedly connected to filter box 2. A slot 15 is opened at the top of shell 402. One side of abutment block 403 is slidably connected to slot 15.

[0029] In this embodiment: there are four locking blocks 401, each group of locking blocks 401 corresponds to a filter plate 10 and is located on both sides of the filter plate 10, so that the filter plate 10 obtains a more balanced and stable support force in the filter box 2. A mounting plate 301 is fixedly connected to one side of the heat exchanger 7, and a fan is fixedly connected to one side of the mounting plate 301, which can actively accelerate the air flow speed on the surface and inside of the heat exchanger 7. There are two filter plates 10, which can filter the air entering the inner cavity of the filter box 2. The cleaned dust will fall into the bottom of the inner cavity of the filter box 2. By pulling the connecting rod 12 to drive the pull plate 11, the dust in the inner cavity of the filter box 2 can be carried out. The filter screen 13 can prevent the fallen dust from entering the inner cavity of the air inlet pipe 14. An air pump is fixedly connected to one side of the air inlet pipe 14 for drawing external air into the filter box 2. The slot 15 provides precise guidance and limit for the locking blocks 401.

[0030] The implementation principle of this utility model is as follows: During use, air enters the filter box 2 through the air inlet pipe 14. The filtered air enters the air compressor 6 through the air outlet pipe 5 for compression, increasing the air pressure. Then, it enters the heat exchanger 7 through pipes to cool the compressed high-temperature air, lowering the air temperature to a suitable operating temperature range for the adsorption tower 8. The air then enters the adsorption tower 8, where, through the pressure swing adsorption principle, the molecular sieve adsorbent adsorbs impurities such as nitrogen from the air under high pressure, thus separating oxygen. The separated oxygen then enters the oxygen buffer tank 9. After prolonged use, excessive dust accumulates on the surface of the filter plate 10, at which point the motor 302 can be started. The motor 302 drives the sector gear 303 to rotate. 303 drives the toothed plate 304 to move, the toothed plate 304 drives the moving frame 305 to move, the moving frame 305 drives the brush 308 to move and compress the first spring 307. When the sector gear 303 disengages from the toothed plate 304, the first spring 307 extends and drives the moving frame 305 to reset. The toothed plate 304 follows the moving frame 305 to reset. When the filter plate 10 needs to be replaced, the pull rod 405 is pulled, the pull rod 405 drives the stop block 403 to move, the stop block 403 disengages from the locking state with the locking block 401 and compresses the second spring 404. At this time, the filter plate 10 can be pulled out. When the pull rod 405 is released, the second spring 404 extends and drives the stop block 403 to reset. The pull rod 405 follows the stop block 403 to reset.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
