[0042] See also Figure 1-5 , the utility model provides a new technical solution: a self-cleaning hollow fiber membrane column, comprising a cylinder 1, the cylinder 1 is hollow inside;

[0043] Wherein, a filter element is arranged in the cylinder 1;

[0044] The outer surface of the cylinder 1 is fixedly sleeved with two first flanges 3;

[0045] Among them, two sealing covers 2 are arranged on the left and right sides of the cylinder 1;

[0046] Among them, a mounting mechanism is arranged on the cylinder 1, and the mounting mechanism includes a second flange 4, a fixing block 5, a rotating shaft 6, a worm 7, a handle 8, a self-cleaning mechanism 9, a connecting groove 10, a connecting block 11, a worm wheel 12 and an inner groove 13.

[0047] Furthermore, the two second flanges 4 are fixedly connected to the two sealing covers 2;

[0048] Among them, two fixing blocks 5 are fixedly connected to the outer surface of the cylinder 1;

[0049] The two fixing blocks 5 are arranged in a mirror image.

[0050] Furthermore, two rotating shafts 6 are rotatably sleeved on two fixed blocks 5 through bearings;

[0051] Among them, two inner grooves 13 are provided on two fixing blocks 5;

[0052] Among them, the two worms 7 are rotatably connected between the upper and lower inner walls of the two inner grooves 13;

[0053] The upper ends of the two worm gears 7 rotate and penetrate the upper surfaces of the two fixing blocks 5 .

[0054] Further, two handles 8 are fixedly connected to the upper ends of the two worm screws 7;

[0055] The two worm gears 12 are fixedly sleeved on the outer surfaces of the two rotating shafts 6;

[0056] Among them, the two worm gears 12 are located in the two inner grooves 13;

[0057] The two connection grooves 10 are both formed on the outer surfaces of the first flange 3 and the second flange 4 .

[0058] Furthermore, the two connection slots 10 are arranged in a mirror image;

[0059] The inner walls of the two adjacent sides of the front and rear connecting grooves 10 are arc surfaces;

[0060] The two rotating shafts 6 are slidably connected to the connecting grooves 10 on the front and rear sides;

[0061] The cylinder 1 and the sealing cover 2 are provided with a self-cleaning mechanism 9, which includes an inlet, a tap water outlet, a purified water outlet and the like.

[0062] Furthermore, four connecting blocks 11 are fixedly connected to the outer surfaces of the two rotating shafts 6;

[0063] The outer surfaces of the two adjacent sides of the left and right connecting blocks 11 are inclined surfaces;

[0064] The two opposite outer surfaces of the two first flanges 3 are slidably connected to the two adjacent outer surfaces of the left and right connecting blocks 11;

[0065] Wherein, rubber pads are provided on the adjacent outer surfaces of the two first flanges 3 .

[0066] Furthermore, the filter element is made of hollow fiber ultrafiltration membrane filter material, and the working materials and installation methods of the filter element and the self-cleaning mechanism 9 are the prior art in the existing public patent: integrated ultrafiltration membrane water purifier CN201721177134.6, and will not be elaborated.

[0067] Furthermore, when the handle 8 is rotated, the handle 8 rotates to drive the worm 7 to rotate, and the worm 7 synchronously drives the worm wheel 12 and the rotating shaft 6 to rotate, thereby synchronously driving the connecting blocks 11 on the left and right sides to rotate;

[0068] As mentioned above, in the initial state, the connecting block 11 is in a horizontal state, at this time, the second flange 4 can be covered with the first flange 3, and during the covering process, the second flange 4 is close to the first flange 3. In this process, the rotating shaft 6 and the connecting block 11 will pass through the connecting groove 10 until the two first flanges 3 are covered with the two second flanges 4. At this time, the handle 8 is turned to drive the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 synchronously drives the connecting block 11 to rotate around the rotating shaft 6. During the rotation of the connecting blocks 11 on the left and right sides, the inclined surfaces thereof contact and slide with the outer surfaces on both sides of the two second flanges 4 opposite to each other, and are connected in a sliding manner. During the rotation of the connecting block 11, the two second flanges 4 are given a thrust to approach each other, so that the two second flanges 4 are more closely fitted with the two first flanges 3, thereby achieving the sealing of the cylinder 1, and then achieving the sealing of the hollow fiber membrane column. The installation is convenient and quick, and it is also convenient for the disassembly and replacement of the hollow fiber membrane column, and the disassembly does not require the use of tools, which saves effort and makes the hollow fiber membrane column more flexible, thereby increasing the practicality of the hollow fiber membrane column.

[0069] Furthermore, in the present solution, the worm 7 is meshed with the worm wheel 12 and the self-locking principle of the worm gear meshing is used, so that only the worm can drive the worm wheel to rotate, and the worm wheel cannot drive the worm to rotate, so as to achieve the positioning of the connecting block 11 and avoid the connection block 11 from rotating without turning the handle 8, thereby increasing the stability of the installation of the hollow fiber membrane column.

[0070] Working principle: When the device is used, by turning the handle 8, the handle 8 rotates to drive the worm 7 to rotate, and the worm 7 synchronously drives the worm wheel 12 and the rotating shaft 6 to rotate, thereby synchronously driving the connecting blocks 11 on the left and right sides to rotate;

[0071] As mentioned above, in the initial state, the connecting block 11 is in a horizontal state, at this time, the second flange 4 can be covered with the first flange 3, and during the covering process, the second flange 4 is close to the first flange 3. In this process, the rotating shaft 6 and the connecting block 11 will pass through the connecting groove 10 until the two first flanges 3 are covered with the two second flanges 4. At this time, the handle 8 is turned to drive the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 synchronously drives the connecting block 11 to rotate around the rotating shaft 6. During the rotation of the connecting blocks 11 on the left and right sides, the inclined surfaces thereof contact and slide with the outer surfaces on both sides of the two second flanges 4 opposite to each other, and are connected in a sliding manner. During the rotation of the connecting block 11, the two second flanges 4 are given a thrust to approach each other, so that the two second flanges 4 are more closely fitted with the two first flanges 3, thereby achieving the sealing of the cylinder 1, and then achieving the sealing of the hollow fiber membrane column. The installation is convenient and quick, and it is also convenient for the disassembly and replacement of the hollow fiber membrane column, and the disassembly does not require the use of tools, which saves effort and makes the hollow fiber membrane column more flexible, thereby increasing the practicality of the hollow fiber membrane column.
