DETAILED DESCRIPTION
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings. Example
[0022] Reference Figures 1 to 7 The utility model discloses a disassembly tool for the end cover and membrane shell 10 of a CDRO membrane module, comprising a first fixing plate 1 and a plurality of guide posts 2 fixedly connected to one side of the first fixing plate 1, and a second fixing plate 3 is slidably connected to the outer circumference of the plurality of guide posts 2. A guide sleeve 4 is fixedly connected to the side of the second fixing plate 3 close to the first fixing plate 1, and an opening is provided at the inside of the guide sleeve 4 corresponding to the side of the second fixing plate 3 away from the first fixing plate 1.
[0023] A central shaft 5 is movably provided on one side of the first fixing plate 1, and the central shaft 5 passes through the guide sleeve 4, and the central shaft 5 is threadedly connected to the guide sleeve 4. A clamping portion 6 is provided on one side of the first fixing plate 1, and a limiting portion 7 is provided on one side of the second fixing plate 3.
[0024] In this embodiment, a plurality of guide posts 2 are arranged in a rectangular shape. The central shaft 5 is connected to the first fixed plate 1 through a travel linear bearing, so that the central shaft 5 can rotate relative to the first fixed plate 1 and can also slide linearly relative to the first fixed plate 1 .
[0025] The CDRO membrane assembly includes an upper end cover 9, a membrane shell 10, a lower end cover 11 and a central tie rod 12. The upper end cover 9 and the lower end cover 11 are respectively installed on the top and bottom surfaces of the membrane shell 10. The central tie rod 12 passes through the upper end cover 9, the membrane shell 10 and the lower end cover 11. This is the prior art.
[0026] When the membrane assembly needs to be disassembled, the lower end cover 11 is first fitted with the second fixing plate 3 , at which time the central tie rod 12 is partially inserted into the guide sleeve 4 , and the end face of the central tie rod 12 is fitted with the end face of the central shaft 5 .
[0027] In a further preferred embodiment of the present invention, Figure 1 As shown, the clamping portion 6 includes two third fixing plates 61 fixedly connected to one side of the first fixing plate 1 , one side of the third fixing plate 61 is threadedly connected to an adjusting rod 62 , and one end of the adjusting rod 62 is fixedly connected to a fixing block 63 .
[0028] In this embodiment, the adjusting rod 62 is rotated to drive the adjusting rod 62 and the fixing block 63 to move toward the membrane shell 10 until both fixing blocks 63 are in contact with the membrane shell 10, thereby clamping and fixing the membrane shell 10. The fixing block 63 is made of rubber to avoid damage to the membrane shell 10 during the disassembly process. The fixing block 63 pre-tightens the membrane shell 10 through the adjusting rod 62, and can be applied to various types of CDRO membrane modules, with a wide range of applications, simple operation, and high work efficiency.
[0029] In a further preferred embodiment of the present invention, Figure 7 As shown, the limiting part 7 includes a plurality of fixing columns 71 fixedly connected to one side of the second fixing plate 3, and the side of the fixing column 71 away from the second fixing plate 3 is rotatably connected to a claw 72 through a rotating pin 73. A fixing pin 74 is slidably penetrated through the outer wall of the rotating pin 73, and a part of the fixing pin 74 is slidably inserted into the corresponding fixing column 71.
[0030] In this embodiment, in the initial state, the fixing pin 74 is pulled out, and the claw 72 and the rotating pin 73 can rotate freely. After the membrane assembly is placed on the second fixing plate 3, the claw 72 is rotated so that the claw 72 fits the top surface of the lower end cover 11, and then the fixing pin 74 is inserted to connect the rotating pin 73 with the fixing column 71. At this time, the rotating pin 73 and the claw 72 can no longer rotate.
[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, one end of the central shaft 5 away from the guide sleeve 4 is fixedly connected to a rocker 8 .
[0032] In this embodiment, the rocker 8 facilitates the operator to rotate the central axis 5 .
[0033] The implementation principle of the above embodiment is:
[0034] First, fit the lower end cover 11 with the second fixed plate 3. At this time, the central pull rod 12 is partially inserted into the guide sleeve 4 and contacts the end face of the central shaft 5. Rotate the adjustment rod 62 to drive the adjustment rod 62 and the fixed block 63 to move toward the membrane shell 10 until both fixed blocks 63 fit with the membrane shell 10 to clamp and fix the membrane shell 10. Rotate the claw 72 so that the claw 72 fits with the top surface of the lower end cover 11, then insert the fixing pin 74, and connect the rotating pin 73 with the fixing column 71. At this time, the rotating pin 73 and the claw 72 can no longer rotate.
[0035] Then, the rocker 8 is rotated to drive the central shaft 5 to rotate, and the guide sleeve 4 is threadedly connected to the central shaft 5, so that the guide sleeve 4 and the second fixed plate 3 move toward the direction of the first fixed plate 1, and the second fixed plate 3 drives the lower end cover 11 to move through the limiting portion 7, and the membrane shell 10 is fixed by the clamping portion 6, so the lower end cover 11 can move relative to the mold shell until the lower end cover 11 is separated from the membrane shell 10, at which time the guide sleeve 4 is in contact with the first fixed plate 1.
[0036] Continue to rotate the rocker 8 to drive the central axis 5 to rotate. Since the guide sleeve 4 is in contact with the first fixed plate 1, the second fixed plate 3 can no longer move relative to the first fixed plate 1. Therefore, when the central axis 5 rotates, the second fixed plate 3 drives the first fixed plate 1 to move synchronously in the direction away from the membrane shell 10. The first fixed plate 1 drives the membrane shell 10 to move through the clamping portion 6, and the end face of the central pull rod 12 is in contact with the end face of the central axis 5. Since the central axis 5 does not move horizontally, the central pull rod 12 and the upper end cover 9 cannot move synchronously with the membrane shell 10. Therefore, the upper end cover 9 can move relative to the membrane shell 10 until the upper end cover 9 is separated from the membrane shell 10, and the disassembly of the upper end cover 9 and the lower end cover 11 is completed.
[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
