Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of hydrogen production units, specifically relating to a purification column fixing structure for hydrogen production units. Background Technology
[0002] In the 0.6 Nm³ / h PEM hydrogen production unit, the purification column is connected to the frame only by two ordinary clamps. This single-point fixing method lacks axial restraint, making the clamping force insufficient to offset the vibration and pipeline stress during equipment operation, causing the column to move vertically. Since the purification column is directly and rigidly connected to the water tank cover via a 1 / 2 steel pipe, when the column moves, the steel pipe will transfer the displacement to the water tank cover, causing it to be unable to fit tightly with the water tank body. This will eventually create a gap between the water tank cover and the tank body, affecting the pressure inside the tank and ultimately leading to a deterioration of the hydrogen content in the oxygen.
[0003] In view of this, the present invention provides a purification column fixing structure for hydrogen production units to solve the above problems. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution: a purification column fixing structure for a hydrogen production unit, comprising:
[0005] The guide rail unit includes an inner guide rail for connecting to the frame of the hydrogen production unit, an outer guide rail slidably sleeved on the periphery of the inner guide rail, and a spring buckle disposed between the inner guide rail and the outer guide rail to limit the relative sliding between the two.
[0006] The support unit includes a purification column support container disposed on its surface along the sliding direction of the outer guide rail; and
[0007] The limiting unit includes a purification column clamp located above the purification column support barrel and connected to the outer guide rail.
[0008] Preferably, the spring buckle includes an elastic element disposed within the inner guide rail, and a positioning head connected to the extended end of the elastic element;
[0009] At least one opposite surface of the inner guide rail and the outer guide rail are respectively provided with a matching telescopic hole and a positioning hole, and the positioning head is movably inserted into the telescopic hole and the positioning hole through an elastic element.
[0010] Preferably, the surface of the outer guide rail is further threaded with a guide rail positioning bolt.
[0011] Preferably, the purification column support tank and the outer guide rail are detachably connected by fasteners;
[0012] The purification column support container includes a first purification column support container and a second purification column support container that are connected in parallel.
[0013] Preferably, the purification column clamp and the outer guide rail are detachably connected by fasteners;
[0014] The purification column clamp includes a connecting part, and a first clamp and a second clamp respectively connected to both ends of the connecting part. The first clamp and the second clamp are coaxially arranged with the first purification column support barrel and the second purification column support barrel respectively.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The present invention provides a purification column support bucket to support the bottom of the purification column, thereby providing good axial support. In addition, the purification column clamps can be used to radially restrict the purification column, so as to effectively limit the movement of the purification column.
[0017] 2. This utility model, through the sliding positioning design between the outer guide rail and the inner guide rail, allows the height of the purification column support bucket to be adjusted. This allows the position of the purification column support bucket to be adjusted according to the actual steel pipe length, so as to realize the connection between the purification column and the water tank. At the same time, it also facilitates the assembly of purification columns and water tanks of different heights. Attached Figure Description

[0024] 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.
[0025] This utility model relates to a purification column fixing structure for hydrogen production units, such as... Figures 1-4 As shown, it includes: a guide rail unit 1, and a support unit 2 and a limiting unit 3 connected to the guide rail unit 1.
[0026] The guide rail unit 1 includes an inner guide rail 12 for connecting to the hydrogen production unit frame, an outer guide rail 11 slidably sleeved around the inner guide rail 12, and a spring clip 13 disposed between the inner guide rail 12 and the outer guide rail 11 to limit their relative sliding. The spring clip 13 allows the outer guide rail 11 to slide to a specific position on the inner guide rail 12 and then be fixed, thus adjusting the relative position of the inner and outer guide rails.
[0027] Specifically, such as Figure 4 As shown, the spring buckle 13 includes an elastic element 131 disposed within the inner guide rail 12, and a positioning head 132 connected to the extended end of the elastic element 131. At least one opposing surface of the inner guide rail 12 and the outer guide rail 11 are respectively provided with a matching telescopic hole 121 and a plurality of positioning holes 111. The positioning head 132 is movably inserted through the elastic element 131 into the telescopic hole 121 and the positioning holes 111. In this embodiment, the elastic element 131 is a spring. In its natural state, it is horizontally placed within the inner guide rail 12, with one end fixedly connected to the inner wall of the inner guide rail 12, and the other end (i.e., the extended end) connected and fixedly connected to the positioning head 132 penetrating the telescopic hole 121. A plurality of positioning holes 111 are spaced apart along the height direction of the outer guide rail 11. In use, pressing the positioning head 132 axially compresses the elastic element 131, causing it to contract and retract the end face of the positioning head 132 into the telescopic hole 121. By sliding the outer guide rail 11 to a suitable position, the telescopic hole 121 aligns with the positioning hole 111 on the outer guide rail 11. Under the elastic reset action of the elastic element 131 itself, the positioning head 132 can extend into the positioning hole 111, thereby restricting the sliding between the inner and outer guide rails and achieving fixation.
[0028] Furthermore, a guide rail positioning bolt 14 is threaded through the surface of the outer guide rail 11 to improve the stability after the inner and outer guide rails are fixed. In use, after the inner and outer guide rails slide relative to each other and are fixed, the guide rail positioning bolt 14 is threadedly connected to the outer guide rail 11. With continuous rotation, the end of the guide rail positioning bolt 14 continuously extends into the outer guide rail 11 and presses against the surface of the inner guide rail 12, thereby increasing the maximum static friction between the inner and outer guide rails and making them less prone to slippage. It should be noted that, to ensure that the guide rail positioning bolt 14 can press well against the inner guide rail 12, the guide rail positioning bolt 14 should be connected near the top periphery of the outer guide rail 11 or near the end of the outer guide rail 11.
[0029] The support unit 2 includes a purification column support barrel disposed on its surface along the sliding direction of the outer guide rail 11.
[0030] Specifically, through holes 23 and threaded holes 112 are respectively provided on the opposing surfaces between the purification column support barrel and the outer guide rail 11. By inserting fasteners (such as bolts) into the through holes 23 and threading them into the threaded holes 112, the purification column support barrel can be detachably installed on the surface of the outer guide rail 11.
[0031] Furthermore, the purification column support includes a first purification column support 21 and a second purification column support 22 connected in parallel. Purification columns can be inserted into the first purification column support 21 and the second purification column support 22 respectively, so that multiple purification columns can be supported simultaneously. It should be noted that more support pods can be arranged in parallel according to actual purification column requirements, such as a third, fourth, or fifth purification column support pod.
[0032] The limiting unit 3 includes a purification column clamp located above the purification column support barrel and connected to the outer guide rail 11; the connection method between the purification column clamp and the outer guide rail 11 can be the same as the connection method between the purification column support barrel and the outer guide rail 11, which will not be described again here.
[0033] Specifically, the purification column clamp includes a connecting part 31, and a first clamp 32 and a second clamp 33 respectively connected to both ends of the connecting part 31. The first clamp 32 and the second clamp 33 are coaxially arranged with the first purification column support tank 21 and the second purification column support tank 22, respectively. The diameters of the first clamp 32 and the second clamp 33 are slightly smaller than the diameter of the purification column, so that the purification column can be effectively radially clamped through its elasticity. In use, the purification column is first inserted into the clamp, and then the purification column is pressed down into the corresponding support tank for bottom support, so as to form axial support for the purification column. It is best to connect the top of the purification column to the water tank through a steel pipe, so as to effectively limit the movement of the purification column by restricting the radial and axial movement of the purification column.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
