DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present utility model with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0020] As Figures 1 to 4As shown in the figure, a water treatment device based on MBR includes an MBR membrane tank 1. Two U-shaped moving frames 2 are slidably connected to the MBR membrane tank 1. Mounting seats 3 are fixedly connected to the top sides of the two U-shaped moving frames 2. Guide rails 4 are fixedly installed on one side of each of the two mounting seats 3. Sliding seats 5 are slidably connected to the outer surfaces of the two guide rails 4. Rack bars 6 are fixedly installed on the sides of the two sliding seats 5 away from the guide rails 4. Motor seats 7 are fixedly installed on one side of each of the two mounting seats 3. Driving motors 8 are fixedly installed on one side of each of the two motor seats 7. Output ends of the two driving motors 8 are fixedly connected to gears 9 that mesh with the rack bars 6. U-shaped mounting frames 10 are fixedly connected to the sides of the two rack bars 6 away from the sliding seats 5. Connecting plates 11 are clamped inside the two U-shaped mounting frames 10. An MBR membrane structure 12 is fixedly installed on the bottom sides of the two connecting plates 11. Fixing jacks 13 are formed on one side of each of the two connecting plates 11. Fixing springs 14 are fixedly connected to one side of each of the two U-shaped mounting frames 10. Fixing plug rods 15 are fixedly connected to the ends of the two fixing springs 14 away from the U-shaped mounting frames 10. A driving mechanism 16 for adjusting the position of the U-shaped moving frame 2 is arranged on the MBR membrane tank 1. When installing or disassembling the MBR membrane structure 12, first pull the fixing plug rod 15 to separate it from the U-shaped mounting frame 10. At this time, the fixing spring 14 is in a stretched state. Then, insert the connecting plate 11 into the inside of the U-shaped mounting frame 10. At this time, the positions of the fixing plug rod 15 and the fixing jack 13 correspond to each other. Then, slowly release the fixing plug rod 15. Under the reaction force of the fixing spring 14, the fixing plug rod 15 is inserted into the inside of the fixing jack 13, thus completing the operation of connecting the MBR membrane structure 12 and the connecting plate 11. Then, start the driving motor 8 to rotate the gear 9, so that the rack bar 6 drives the sliding seat 5 to move downward. At this time, the MBR membrane structure 12 moves downward and enters the inside of the MBR membrane tank 1, thereby placing the MBR membrane structure 12 into the inside of the MBR membrane tank 1, making the operation of placing the MBR membrane structure 12 relatively simple. Similarly, it is convenient for the MBR membrane structure 12 to be removed from the inside of the MBR membrane tank 1 and for the MBR membrane structure 12 to be separated from the connecting plate 11.

[0021] As an optional technical solution of the present invention, the MBR membrane structure 12 includes a mounting bracket 1201, an MBR membrane 1202, and moving wheels 1203. The bottom end of the connecting plate 11 is fixedly connected to the mounting bracket 1201. A plurality of MBR membranes 1202 are arranged on the mounting bracket 1201. The bottom end of the mounting bracket 1201 is fixedly installed with the moving wheels 1203. When it is necessary to adjust the position of the MBR membrane structure 12, the mounting bracket 1201 can move smoothly inside the MBR membrane tank 1 through the moving wheels 1203.

[0022] As an alternative technical solution of the present utility model, the driving mechanism 16 includes a mounting plate 1601, a lead screw 1602, a belt pulley 1603, a crank 1604 and a connecting block 1605. Mounting plates 1601 are fixedly connected to two opposite sides of the MBR membrane tank 1601. One lead screw 1602 is rotatably connected to one side of the two mounting plates 1601 through bearings. One end of the lead screw 1602 is fixedly connected to a belt pulley 1603. One end of one lead screw 1602 is fixedly connected to a crank 1604. There are two belt pulleys 1603, and the two belt pulleys 1603 are connected by a belt drive. A connecting block 1605 fixedly connected to the U-shaped moving frame 2 is threadedly connected to the outer surface of the lead screw 1602. When it is necessary to adjust the position of the MBR membrane structure 12, one lead screw 1602 is rotated by the crank 1604. At this time, under the drive of the belt pulley 1603 and the belt, the other lead screw 1602 rotates simultaneously. At this time, the connecting block 1605 will drive the U-shaped moving frame 2 to move, and at this time, the MBR membrane structure 12 will move accordingly, so that the MBR membrane structure 12 can be adjusted to a suitable position.

[0023] As an alternative technical solution of the present utility model, the MBR membrane structure 12 is located inside the MBR membrane tank 1. The width of the MBR membrane structure 12 is smaller than the width of the internal dimension of the MBR membrane tank 1, so that the MBR membrane structure 12 can smoothly enter the inside of the MBR membrane tank 1.

[0024] As an alternative technical solution of the present utility model, the length of the rack 6 is greater than the height of the MBR membrane structure 12, so that the MBR membrane structure 12 can be completely removed from the inside of the MBR membrane tank 1.

[0025] As an alternative technical solution of the present utility model, a part of the fixed plug 15 is located inside the fixed spring 14. The fixed plug 15 penetrates through the U-shaped mounting bracket 10, and the fixed plug 15 is slidably connected to the U-shaped mounting bracket 10. The fixed plug 15 is adapted to the size of the fixed socket 13, so that the fixed plug 15 can smoothly move and be inserted into the inside of the fixed socket 13.

[0026] A water treatment device based on MBR, and the working principle of placing the MBR membrane structure 12 inside the MBR membrane tank 1 is as follows:

[0027] 1) Pull the fixed plug 15 to separate it from the U-shaped mounting bracket 10. At this time, the fixed spring 14 is in a stretched state;

[0028] 2) Make the connecting plate 11 snap into the inside of the U-shaped mounting bracket 10. At this time, the positions of the fixed plug 15 and the fixed socket 13 correspond to each other;

[0029] 3) Slowly release the fixed insertion rod 15, and under the reaction force of the fixed spring 14, insert the fixed insertion rod 15 into the inside of the fixed insertion hole 13, thereby completing the operation of connecting the MBR membrane structure 12 and the connecting plate 11;

[0030] 4) Start the drive motor 8 to rotate the gear 9, so that the rack 6 drives the sliding seat 5 to move downward. At this time, the MBR membrane structure 12 moves downward and enters the inside of the MBR membrane tank 1.

[0031] In summary, for the water treatment device based on MBR, through the cooperative setting of the U-shaped moving frame 2, the mounting seat 3, the guide rail 4, the sliding seat 5, the rack 6, the motor seat 7, the drive motor 8, the gear 9, the U-shaped mounting frame 10, the connecting plate 11, the MBR membrane structure 12, the fixed insertion hole 13, the fixed spring 14, the fixed insertion rod 15 and the drive structure 16, it can not only adjust the position of the MBR membrane structure 12, but also adjust the height of the MBR membrane structure 12, which is convenient for removing the MBR membrane structure 12 from the inside of the MBR membrane tank 1 and for installing and disassembling the MBR membrane structure 12, reducing the labor intensity of the operator for lifting the height of the MBR membrane structure 12 and improving the efficiency of installing and disassembling the MBR membrane structure 12.
