Description

Technical Field

[0001] The utility model relates to the technical field of pressure swing adsorption devices, in particular to a pressure swing adsorption device. Background Art

[0002] Pressure swing adsorption device is a device that uses the difference in the amount of gas adsorbed on solid adsorbents at different pressures to achieve gas separation and purification through periodic pressure changes. It usually consists of multiple adsorption beds filled with different adsorbents, and the flow of gas between the adsorption beds is controlled by valves to achieve gas separation and purification.

[0003] The existing authorization announcement number is CN220779625U, which discloses a pressure swing adsorption device for hydrogen purification including a purification component and a support component. The purification component includes a purification tower and a tower body connecting pipe installed on one side of the purification tower. A positioning plate is installed in the utility model. When the staff puts the device bracket into the base along the installation groove, when the bracket moves to the positioning plate, the cylinder installed at the bottom of the positioning plate drives the positioning plate to move downward until the bracket penetrates into the positioning groove to complete the limit. When the bracket enters the positioning groove, the device moves downward as a whole, and the buffer installed at the bottom of the purification tower and the adsorption tower contacts the sponge and squeezes it downward during movement. The buffer spring installed at the bottom can drive the support member and the sponge to shrink, cooperate with the installation groove and the positioning plate to increase the positioning installation effect, and can provide convenience for the staff during installation. The device can be quickly installed and provide limit and support without being fixed, thereby increasing the work efficiency of the staff.

[0004] The above technical solution can provide convenience for the workers during installation, and the device can be quickly installed and provided with limit and support without being fixed, but a cylinder is set in each positioning groove, which is expensive. At the same time, the device is not fixed and limited after positioning and installation, which may cause the device to shake or fall when it is in working state or impacted by the outside world, thus causing safety hazards to the surrounding environment and equipment. Therefore, we provide a pressure swing adsorption device. Utility Model Content

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] The present utility model provides a technical solution: As Figures 1-5As shown in the figure, in this embodiment, a pressure swing adsorption device includes: a fixing mechanism 1, the fixing mechanism 1 includes a mounting base 11, two mounting grooves 12 are opened at the top of the mounting base 11, a pressure swing adsorption device 13 is arranged on the top of the mounting base 11, a plurality of support columns 14 are arranged at the bottom of the adsorption device, threaded holes 15 are opened on one side of the plurality of support columns 14 facing each other, fixing members 16 are arranged in the clamping grooves opened on both sides of the mounting base 11, a plurality of positioning holes 17 are annularly arranged outside the plurality of fixing members 16, threaded portions 18 are opened at one ends of the plurality of fixing members 16 close to the support columns 14, a plurality of support columns 14 are fixedly connected to the bottom of the adsorption device, one end of the fixing member 16 close to the threaded portion 18 penetrates through the clamping groove opened on one side of the mounting base 11 and is threadedly connected to the inner wall of the threaded hole 15, a plurality of wrench blocks 110 are arranged on both sides of the top of the mounting base 11, grooves 19 are opened on both sides of the top of the mounting base 11 close to the wrench blocks 110, movable rods 111 are arranged inside the plurality of grooves 19, the bottom of the wrench block 110 is in contact with the top of the mounting base 11, the top of the movable rod 111 is movably connected to the inside of the wrench block 110, springs 112 are arranged outside the plurality of movable rods 111, positioning blocks 113 are arranged at one ends of the plurality of movable rods 111 far from the wrench blocks 110, the bottom end of the movable rod 111 passes through the clamping groove opened on the top of the mounting base 11 and the inner ring of the spring 112 and is fixedly connected to the top end of the positioning block 113, the bottom end of the positioning block 113 is clamped with the inner wall of the positioning hole 17, the top end of the spring 112 is fixedly connected to one side of the inner wall of the groove 19 close to the wrench block 110, and the bottom end of the spring 112 is fixedly connected to one end of the positioning block 113 close to the movable block. A positioning mechanism 2 is arranged on the bottom side of the inner wall of the mounting groove 12.

[0025] In this embodiment, when the pressure swing adsorption device 13 needs to be positioned and installed, the staff needs to move the device to the positioning plate 21 inside the mounting groove 12, position the device through the positioning mechanism 2, and then the staff can accordingly move the wrench block 110 upward. Therefore, when the wrench block 110 is subjected to a force, it will pull the movable rod 111 and the positioning block 113 upward. The positioning block 113 will sink into the groove 19. At the same time, when the spring 112 is pushed upward by the positioning block 113, it will generate a compressive deformation. The staff penetrates one end of the fixing member 16 close to the threaded portion 18 through the clamping groove opened on one side of the mounting base 11 and threadedly connects the threaded portion 18 with the threaded hole 15. Therefore, the support column 14 and the pressure swing adsorption device 13 will be fixed and limited, avoiding the phenomenon of shaking or toppling when the device is impacted by the outside world. The staff releases the wrench block 110, and then the spring 112 will release the elastic force to push the positioning block 113 to be clamped in the corresponding positioning hole 17 opened outside the fixing member 16, thereby limiting and fixing the fixing member 16 and preventing loosening between the threaded portion 18 and the threaded hole 15.

[0026] Such as Figures 1-5As shown, the positioning mechanism 2 includes a positioning plate 21, the bottom of the positioning plate 21 is fixedly connected to the top of the buffer spring 24, a plurality of positioning grooves 22 are provided on the bottom side of the inner wall of the two mounting grooves 12, the bottom end of the buffer spring 24 is fixedly connected to the bottom side of the inner wall of the positioning groove 22, and sponge pads 23 are embedded in the plurality of positioning grooves 22.

[0027] In this embodiment, due to the weight of the pressure swing adsorption equipment 13 itself, when the bottom of the support column 14 moves to the positioning plate 21, the positioning plate 21 will drop into the positioning groove 22, and the sponge pad 23 and the buffer spring 24 will shrink and deform due to pressure. Therefore, the positioning plate 21 and the positioning groove 22 will achieve the positioning effect of the support column 14, ensuring that the support column 14 can be accurately installed in the predetermined position.

[0028] The utility model provides a pressure swing adsorption device, and the specific working principle is as follows:

[0029] When the pressure swing adsorption device 13 needs to be positioned and installed, the staff moves the device to the positioning plate 21 in the installation groove 12. Since the pressure swing adsorption device 13 itself is heavy, when the device is placed on the positioning plate 21, the positioning plate 21 will drop into the positioning groove 22 due to gravity. At this time, the sponge pad 23 and the buffer spring 24 under the positioning plate 21 will be subjected to pressure, thereby shrinking and deforming. Therefore, the device will have a limiting effect. Subsequently, the staff can push the block 110 upward so that the block 110 is subjected to a certain force. Under the action of this force, the block 110 will pull the movable rod 111 and the positioning block 113 connected thereto to move upward. As the block 113 moves upward, it will gradually sink into the groove 19. At the same time, the spring 112 connected to the positioning block 113 will also be squeezed, resulting in contraction deformation. Next, the staff will bring one end of the fixing part 16 close to the threaded portion 18 and pass it through the slot opened on one side of the mounting seat 11. The purpose of this is to thread the threaded portion 18 with the threaded hole 15. Once the threaded connection is completed, the support column 14 and the pressure swing adsorption device 13 will be fixed and limited. By loosening the pull block 110, the spring 112 will lose the squeezing force and release the elastic force to push the positioning block 113 to be clamped in the corresponding positioning hole 17 opened on the outside of the fixing part 16, and the fixing part 16 will be limited and fixed.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
