Description

Technical Field

[0001] This utility model relates to the technical field of membrane separators for nitrogen production, and specifically to a disassembly auxiliary device for a membrane separator for nitrogen production. Background Technology

[0002] Membrane separation nitrogen production technology utilizes the differences in permeability of hollow fiber membranes to different gases in the air to separate nitrogen from gases such as oxygen, thereby producing nitrogen. This technology can continuously produce nitrogen by connecting multiple membrane separators in parallel, depending on the required gas volume.

[0003] The membrane tubes of membrane separators used for nitrogen generation are cylindrical with hexagonal ends. These hexagonal ends are typically temporarily sealed with nuts to prevent dust intrusion. Before using the membrane separator, these temporary nuts must be removed. However, currently, there is a lack of clamping devices for disassembling the membrane separator, making nut removal inconvenient and lacking effective support points. Therefore, to improve the efficiency and convenience of nut removal from the membrane tubes, a disassembly auxiliary device for membrane separators used for nitrogen generation is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for disassembling a membrane separator used in membrane nitrogen production, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A disassembly auxiliary device for a membrane separator used in nitrogen production includes a worktable, a fixed back plate, a sliding groove, a slider, a clamping mechanism, and an adjusting mechanism. The fixed back plate is located at the rear end of the upper surface of the worktable. Two parallel sliding grooves are provided on the upper surface of the worktable, with a slider slidably disposed in each groove. The clamping mechanism includes two sets of clamping components and an auxiliary ejection component. Each clamping component includes a fixed clamping block, a movable clamping block, a first sliding rod, and a first spring. A movable clamping block is fixed above each slider, and the two movable clamping blocks are symmetrically arranged. The movable clamping blocks follow the slider along... The slide moves back and forth. A first slide rod is fixed horizontally on the rear end face of each movable clamping block. The other end of the first slide rod is slidably connected to the fixed back plate. A first spring is installed on the outside of each first slide rod. One end of the first spring is fixed to the rear end face of the movable clamping block, and the other end of the first spring is fixed to the front end face of the fixed back plate. A strip groove is provided in front of the two slides on the upper surface of the worktable. An auxiliary ejection component is provided in the strip groove. A fixed clamping block is fixed on the upper surface of the worktable in front of the auxiliary ejection component and at a position corresponding to the two movable clamping blocks.

[0007] The auxiliary ejection assembly includes a fixed base, two second slide rods, two second springs, and a top plate. The fixed base is fixed in a strip groove. A second slide rod is slidably connected to each end of the fixed base. A second spring is installed on the outside of each second slide rod. A top plate is horizontally fixed above the two second slide rods. One end of each second spring is fixed to the lower end face of the top plate, and the other end of each second spring is fixed to the upper surface of the fixed base.

[0008] The adjustment mechanism includes a base, a bottom plate, a toothed rod groove, several support rod grooves, a toothed rod, several support rods, a gear, two mounting plates, and a rotating rod. The base is placed below the worktable, and a bottom plate is fixed below the base. A toothed rod groove and several support rod grooves are vertically formed inside the base. The toothed rod and several support rods are respectively fixed vertically to the lower surface of the worktable, with the toothed rod slidably positioned in the toothed rod groove. Each support rod is slidably positioned in its support rod groove. Two spaced mounting plates are fixed to the outside of the toothed rod groove. The gear is rotatably mounted between the two mounting plates via the rotating rod. The gear meshes with the toothed rod. Rotating the gear via the rotating rod causes the toothed rod to move up and down within the toothed rod groove, and all the support rods to move up and down within their respective support rod grooves, thereby achieving the up and down movement of the worktable.

[0009] Furthermore, the fixed clamping block and the movable clamping block have the same structure, both including a rectangular block. The front end face of the rectangular block is provided with an inclined surface, a flat surface and a V-shaped groove from top to bottom. A side baffle is also provided on one side of the outer facade of the rectangular block along the length direction.

[0010] Furthermore, a working recess is provided in front of the workbench.

[0011] Furthermore, a horizontal tie rod is fixed between the two movable clamping blocks.

[0012] Furthermore, limit slots are provided at corresponding positions on the two mounting plates. A pin is inserted into the limit slot to lock the gear and prevent it from rotating.

[0013] Furthermore, the number of support rod grooves and support rods are both three.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model is equipped with a sliding groove, a sliding block and a clamping mechanism on the workbench, which can be used to clamp the membrane separator when disassembling the nuts at both ends. The operator can use tools to disassemble the nuts at both ends of the membrane separator.

[0016] 2. This utility model is equipped with an auxiliary pop-out component. After the nuts at both ends of the membrane separator are disassembled, the horizontal pull rod is pulled backward to separate the movable clamping block from the fixed clamping block. At this time, the membrane separator is unrestrained, and the top plate of the auxiliary pop-out component is also freed from the pressure of the membrane separator. The top plate is subjected to the action of the second spring and moves upward, and the auxiliary membrane separator pops out, making it convenient for the operator to pick it up.

[0017] 3. This utility model features an adjustment mechanism located below the worktable. A toothed rod groove and a support rod groove are incorporated into the base. Through the meshing of gears with the toothed rod, rotating the rotating rod causes the gear to move up and down within the toothed rod groove. Simultaneously, the support rod also moves up and down within the support rod groove, thus adjusting the height of the worktable for the convenience of different operators. When the clamping mechanism reaches the appropriate height, a pin is inserted into the limiting slot. The pin locks the gear, preventing its rotation and thus fixing the toothed rod, thereby securing the worktable and improving the adaptability of the device. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0025] Example

[0026] like Figures 1-5 As shown, a disassembly auxiliary device for a membrane separator used in nitrogen production includes a worktable 1, a fixed back plate 2, a slide groove 3, a slider 4, a clamping mechanism 5, and an adjusting mechanism 6. The fixed back plate 2 is located at the rear end of the upper surface of the worktable 1. The upper surface of the worktable 1 has two parallel slide grooves 3, in which a slider 4 is slidably disposed. The clamping mechanism 5 includes two sets of clamping components and an auxiliary ejection component. The clamping components include a fixed clamping block 51, a movable clamping block 52, a first slide rod 53, and a first spring 54. A movable clamping block 52 is fixed above each slider 4, and the two movable clamping blocks 52 are symmetrically arranged. The movable clamping blocks 52 follow the slider 4. The slide bar 52 moves back and forth along the slide 3. A first slide bar 53 is fixed horizontally on the rear end face of each movable clamping block 52. The other end of the first slide bar 53 is slidably connected to the fixed back plate 2. A first spring 54 is installed on the outside of each first slide bar 53. One end of the first spring 54 is fixed to the rear end face of the movable clamping block 52, and the other end of the first spring 54 is fixed to the front end face of the fixed back plate 2. A strip groove 11 is provided in front of the two slide bars 3 on the upper surface of the worktable 1. An auxiliary ejection component is provided in the strip groove 11. A fixed clamping block 51 is fixed on the upper surface of the worktable 1 in front of the auxiliary ejection component and at a position corresponding to the two movable clamping blocks 52.

[0027] Reference Figure 5 As shown, the auxiliary pop-out assembly includes a fixed base 55, two second slide rods 56, two second springs 57, and a top plate 58. The fixed base 55 is fixed in the strip groove 11. A second slide rod 56 is slidably connected to each end of the fixed base 55. A second spring 57 is installed on the outside of each second slide rod 56. A top plate 58 is horizontally fixed above the two second slide rods 56. One end of each second spring 57 is fixed to the lower end face of the top plate 58, and the other end of each second spring 57 is fixed to the upper surface of the fixed base 55.

[0028] The adjusting mechanism 6 includes a base 61, a base plate 62, a toothed rod slide groove 63, several support rod slide grooves 64, a toothed rod 65, several support rods 66, a gear 67, two mounting plates 68, and a rotating rod 69. The base 61 is placed below the workbench 1, and the base plate 62 is fixed below the base 61. The base 61 has a toothed rod slide groove 63 and several support rod slide grooves 64 vertically opened inside. The toothed rod 65 and several support rods 66 are respectively fixed vertically to the lower surface of the workbench 1, and the toothed rod 65 slides. Each support rod 66 is slidably placed in the support rod groove 64 within the toothed rod groove 63. Two spaced mounting plates 68 are fixed on the outside of the toothed rod groove 63. A gear 67 is rotatably mounted between the two mounting plates 68 via a rotating rod 69. The gear 67 meshes with the toothed rod 65. By rotating the gear 67 via the rotating rod 69, the toothed rod 65 moves up and down within the toothed rod groove 63, and all the support rods 66 move up and down within the support rod groove 64, thereby realizing the up and down movement of the worktable 1.

[0029] Reference Figure 4 As shown, the fixed clamping block 51 and the movable clamping block 52 have the same structure, both including a rectangular block 7. The front end face of the rectangular block 7 is provided with an inclined surface 71, a flat surface 72 and a V-shaped groove 73 from top to bottom. A side baffle 74 is also provided on one side of the outer facade of the rectangular block 7 along the length direction.

[0030] A working recess 12 is also provided in front of the workbench 1. The working recess 12 facilitates the operation of the membrane separator 9 by the operator.

[0031] A horizontal pull rod 59 is fixed between the two movable clamping blocks 52. Pulling the horizontal pull rod 59 can cause the movable clamping blocks 52 to move back and forth along the slide groove 3 via the slider 4.

[0032] Reference Figure 2 As shown, limit slots 8 are also provided at corresponding positions on the two mounting plates 68. A pin (not shown in the figure) is inserted into the limit slot 8 to lock the gear 67 and prevent it from rotating.

[0033] In this embodiment, there are three support rod grooves 64 and three support rods 66, which are distributed in a triangular shape. The arrangement of the toothed rods 65 and the support rods 66 can improve the stability of the worktable 1 during the rising and falling process.

[0034] In use, this utility model can first rotate the rotating rod 69 to drive the gear 67 to rotate, thereby causing the toothed rod 65 to move up and down in the toothed rod slide groove 63. At the same time, the support rod 66 will also move up and down in the support rod slide groove 64, thereby driving the worktable 1 to move up and down, which can adjust the height of the worktable 1 and facilitate the use of different operators. When the height of the clamping mechanism 5 is appropriate, a pin (not shown in the figure) is inserted into the limit slot 8. The pin will lock the gear 67 to prevent it from rotating, thereby fixing the toothed rod 65 and fixing the worktable 1 at the appropriate height.

[0035] The membrane separator 9 is placed between the movable clamping block 52 and the fixed clamping block 51 and pressed down. The movable clamping block 52 and the fixed clamping block 51 of the clamping mechanism 5 are separated by the cooperation of the slider 4 and the slide groove 3, so that the membrane separator 9 falls into it and is placed above the auxiliary ejection assembly. At this time, the slider 4 loses pressure and returns to its original position under the elastic force of the first spring 54, clamping the membrane separator 9. The V-shaped grooves 73 on the movable clamping block 52 and the fixed clamping block 51 match the hexagonal ends at both ends of the membrane separator 9, so that the top plate 58 of the auxiliary ejection assembly moves down to be flush with the upper surface of the worktable 1. At this time, the membrane separator 9 is clamped and fixed by the movable clamping block 52 and the fixed clamping block 51. The side baffles 74 on the movable clamping block 52 and the fixed clamping block 51 play a role in blocking the membrane separator 9 and preventing the membrane separator 9 from detaching from both sides. At this time, the operator can use tools to disassemble the nuts at both ends of the membrane separator 9.

[0036] After the disassembly is completed, pull the horizontal lever 59 to the rear of the workbench 1. At this time, the movable clamp 52 and the fixed clamp 51 separate. Under the action of the second spring 57, the top plate 58 pops up and pushes out the membrane separator 9 so that the membrane separator 9 can be picked up.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
