[0035] The inner wall length of the sliding frame 804 is the same as the diameter length of the row pipe 7. A positioning groove 809 is provided on one side of the outer plate 2 relative to the inner wall of the sliding frame 804. The inner wall of the sliding frame 804 rotates to one side of the positioning groove 809. The positioning groove 809 achieves the effect of positioning the rotation angle of the sliding frame 804. Arc blocks 810 are fixedly connected on both sides of the support plate 807. The inner wall of the arc block 810 abuts against the row pipe 7. The support plate 807 drives the arc block 810 to fit the arc surface of the row pipe 7. The arc block 810 prevents the row pipe 7 from moving. The arc surface of the fixing rod 801 is fixedly connected with a clamping plate 811. One side of the clamping plate 811 abuts against the sliding frame 804. The sliding frame 804 moves between the outer plate 2 and the clamping plate 811. The clamping plate 811 achieves the effect of preventing the sliding frame 804 from moving horizontally.

[0036] like Figure 5 As shown, the shielding structure 9 includes two connecting plates 91, one side of the two connecting plates 91 is fixedly connected to the base 1, the upper surfaces of the two connecting plates 91 are fixedly connected with support rods 92, the arc surface of the support rods 92 is rotatably connected to the rotating cylinder 93, the arc surface of the rotating cylinder 93 is fixedly connected to an extension plate 94, and the side of the extension plate 94 away from the rotating cylinder 93 is fixedly connected to a baffle 95, one side of the two connecting plates 91 is fixedly connected to an L-shaped rod 96, and the long arms of the two L-shaped rods 96 are fixedly connected to a magnet 97, the baffle 95 is an iron plate, the baffle 95 rotates and engages with the magnet 97, the magnet 97 plays a role in further limiting the baffle 95, the surface of the baffle 95 is provided with a groove 98, the groove 98 is located at the position of the baffle 95 close to the two sides of the extension plate 94, the baffle 95 is pulled with the help of the groove 98, and the groove 98 has the effect of facilitating personnel to pull the baffle 95 away from the magnet 97.

[0037] Working principle: when it is necessary to perform electrically driven membrane separation on a high-salt water body, the water body is first discharged into the ion exchange membrane 3 through the discharge pipe 7 with the help of the suction pipe 6, and then direct current is input into the direct current plate 4 through the wire 5. The direct current plate 4 transmits electricity to the ion exchange membrane 3. Under the action of the direct current electric field in the ion exchange membrane 3, the ion exchange membrane 3 has selective permeability to anions and cations, so that the anions and cations in the water body migrate in a directional manner, so that the ions in the water body between the ion exchange membranes 3 are separated, thereby achieving the purpose of separation, purification and concentration of the electrolyte solution. Subsequently, the high-salt water body separated in the ion exchange membrane 3 is discharged through the discharge pipe 7 again with the help of the suction pipe 6. During the disassembly and cleaning process of the discharge pipe 7 after long-term use, the personnel first removes the connecting piece between the lower discharge pipe 7 and the suction pipe 6 with the help of tools. At this time, the arc block 810 supports the discharge pipe 7 with the help of the support plate 807, so that the discharge pipe 7 can be effectively supported during the disassembly process to reduce the use of personnel. After the tube 7 is moved out, the opening of the extraction tube 6 is covered by the shielding structure 9, and then the screw 803 is rotated to the side away from the outer plate 2 by the driving ball 808 with the help of the inner groove. The driving ball 808 plays a role in better rotating the screw 803, and the screw 803 is separated from the inner wall of the limiting hole 805 through the top plate 802. Then the sliding frame 804 is rotated, and the sliding frame 804 rotates and moves between the outer plate 2 and the card plate 811. The card plate 811 prevents the sliding frame 804 from moving horizontally until When the inner wall of the sliding frame 804 rotates from the arc surface of the fixing rod 801 to be aligned with the positioning groove 809 and then stops rotating, the positioning groove 809 achieves the effect of positioning the rotation angle of the sliding frame 804. At this time, the sliding frame 804 is lifted, and the connecting rod 806 drives the arc block 810 to press against the arc surface of the upper row pipe 7 through the sliding frame 804 with the help of the support plate 807. The arc block 810 prevents the row pipe 7 from moving. At this time, the upper row pipe 7 is supported, so that the upper row pipe 7 can be disassembled and cleaned.

[0038] When it is necessary to cover the pipe opening of the lower suction tube 6, the baffle 95 is first rotated with the help of the groove 98. The groove 98 makes it convenient for personnel to pull the baffle 95 to separate from the magnet 97. The extension plate 94 drives the rotating drum 93 to rotate from the arc surface of the support rod 92 through the baffle 95 until the baffle 95 rotates and fits with the magnet 97. The magnet 97 plays a role in further limiting the baffle 95. The magnet 97 is attracted to the baffle 95 by magnetic force. At this time, the baffle 95 is attracted and limited above the pipe opening of the suction tube 6, so as to cover the pipe opening of the suction tube 6 and prevent debris from falling into the suction tube 6.
