[0002] The container VPSA device (Vakuum Pressure Swing Adsorption, VPSA) is a device that uses adsorbents to separate and purify gases. It is mainly used to separate and purify nitrogen and oxygen in the air to achieve the required purity. The VPSA device is usually composed of multiple containers, each of which contains an adsorbent bed, a compressed air intake system, an adsorbent bed regeneration system, and a product gas collection system.

DETAILED DESCRIPTION

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] The utility model provides a container VPSA device which is easy to transport, comprising a box body 1 and an oxygen production device 2 arranged inside the box body 1, characterized in that support plates 101 are vertically arranged on both sides of the bottom of the box body 1, two groups of limit components 3 are arranged at the bottom of the box body 1, the limit components 3 are connected by connecting plates 4, a driving mechanism 5 is arranged between the limit components 3, the driving mechanism 5 is connected to the connecting plates 4, the top of the limit components 3 is slidably connected to the box body 1, and the driving mechanism 5 pushes the limit components 3 to move outside the box body 1.

[0028] The support plate 101 forms a specific space between the bottom of the box body 1 and the standing surface of the box body 1. The driving mechanism 5 is arranged in the middle of the specific space, and the limit assemblies 3 are symmetrically distributed on both sides of the driving mechanism 5, so that the driving mechanism 5 can drive the two limit assemblies 3 to work at the same time. When the container VPSA device is placed on the transport vehicle, the driving mechanism 5 is started. When the driving mechanism 5 works, the limit assemblies 3 extend from the bottom of the box body 1 until they fit with the side plate, thereby fixing the container VPSA device on the transport vehicle. The limit assemblies 3 can be extended and retracted arbitrarily from the bottom of the box body 1 by power drive, and only extend and fix the box body 1 during transportation, thereby improving transportation efficiency.

[0029] The limiting assembly 3 includes limiting rods 301 arranged in pairs at the bottom of the box body 1, brackets 302 located at the ends of the limiting rods 301, and moving blocks 303 slidably connected to the brackets 302. The brackets 302 are provided with at least two groups, each group is provided with two, and are connected to the two ends of the limiting rod 301. The side ends of the moving blocks 303 are fixedly connected to the connecting plate 4. The limiting rod 301 is connected to the driving mechanism 5 through the moving blocks 303 and the connecting plate 4. The connecting plate 4 is arranged on the side of the limiting rod 301 and connects the moving blocks 303 at both ends of the limiting rod 301 to realize motion transmission. The bracket 302 is fixed at the bottom of the box body 1 and is provided with a moving slide rail. The driving mechanism 5 moves to push the connecting plate 4 and the moving block 303 to move. The top of the moving block 303 is connected to the bracket 302 through the slide rail, thereby pushing the limiting rod 301 to move. The slide rails at both ends of the limiting rod 301 bidirectionally control the moving direction of the limiting rod 301 to ensure that the limiting rod 301 accurately extends from the bottom of the box body 1.

[0030] The driving mechanism 5 includes a protective shell 501 fixedly connected to the bottom of the box body 1, and a transmission mechanism 502 disposed in the protective shell 501, and the connecting plate 4 extends to connect with the transmission mechanism 502. The transmission mechanism 502 is disposed at the bottom of the box body 1 through the protective shell 501, and through holes are provided on both sides of the protective shell 501, and the output end of the transmission mechanism 502 is connected to the connecting plate 4 through the through holes. The specific transmission mechanism 502 includes a driving motor 5021 fixed outside the protective shell 501, a worm mechanism 5022 connected to the output end of the driving mechanism 5, a transmission gear set 5023 meshing with each other, and a push plate 5025 fixedly connected to the side end of the rack 5024, wherein a transmission gear set 5023 is connected to the worm wheel in the worm mechanism 5022, and the transmission gear sets 5023 are respectively connected to the racks 5024, and the push plate 5025 on the rack 5024 is fixedly connected to the connecting plate 4, which can be fixedly connected by bolts or the like; a limit groove 5026 is provided under the push plate 5025, and the push plate 5025 is linearly displaced along the limit groove 5026. The worm mechanism 5022 is composed of a worm wheel and a worm, the driving motor 5021 is connected to the worm, the worm wheel is coaxially connected to one of the transmission gear sets 5023, the two transmission gear sets 5023 are meshed with each other, and rotate in opposite directions, thereby driving the corresponding rack 5024 to move, and the rack 5024 moves in opposite directions, pushing the limit rod 301 to move forward and backward or left and right toward the box body 1.

[0031] The transmission gear set 5023 includes an external meshing transmission gear 5023a, a sector gear 5023b coaxially connected to the external meshing transmission gear 5023a, the external meshing transmission gear 5023a is connected to the protective housing 501 through a connecting shaft, the external meshing transmission gear 5023a is located below the rack 5024, and the sector gear 5023b is meshed with the rack 5024 for transmission. The external meshing transmission gears 5023a in the two transmission gear sets 5023 are meshed with each other, the external meshing transmission gear 5023a rotates synchronously with the sector gear 5023b, and the sector gear 5023b is meshed for transmission, pushing the rack 5024 to move linearly. The sector gear 5023b realizes intermittent pushing of the limit rod 301 to move, so that personnel can observe the distance between the limit rod 301 and the side railing of the transport vehicle in time, and conveniently control the drive motor 5021 to stop working.

[0032] Working principle: The hammock hoists the container VPSA device as a whole and places it on the transport vehicle. The drive motor 5021 is started, and the driving force is transmitted to the external meshing transmission gear 5023a and the fan gear 5023b in sequence through the worm mechanism 5022. The external meshing transmission gear 5023a and the fan gear 5023b rotate synchronously, respectively pushing the rack 5024 to move linearly. The rack 5024 pushes the limit rod 301 to move through the connecting plate 4 and the moving block 303. When the limit rod 301 is at the extreme position on the transport vehicle, the drive motor 5021 stops working. The limit rods 301 at both ends of the box body 1 are tightly fitted with the side railings of the transport vehicle to limit the shaking direction of the box body 1.

[0033] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
