Description

Technical Field

[0001] The present invention relates to the field of raw water purification, and in particular to a high-turbidity raw water purification device based on a PTFE modified membrane and a preparation method thereof. Background Art

[0002] At present, when purifying raw water, the existing technology uses a hollow fiber membrane module with a PTFE modified membrane to purify the raw water. During the purification process, impurities in the raw water easily adhere to the surface of the hollow fiber membrane module. After a period of use, the surface of the hollow fiber membrane module is clogged with impurities. Therefore, the hollow fiber membrane module needs to be disassembled and cleaned. In addition, when disassembling the hollow fiber membrane module in the existing technology, the water in the treatment pool needs to be drained before the hollow fiber membrane module immersed in it can be cleaned, which is relatively inconvenient and will affect the treatment efficiency of the raw water.

[0003] Therefore, it is necessary to invent a high-turbidity raw water purification device based on PTFE modified membrane and a preparation method to solve the above problems. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] The present invention provides Figure 1-3The high turbidity raw water purification device based on PTFE modified membrane and its preparation method shown in the figure include a support base 1, a support plate 2 is fixedly connected to the top of the support base 1, two sets of mounting frames 3 are arranged between the two support plates 2, and multiple sets of membrane bundles 4 are arranged at the bottom of each set of mounting frames 3. The upper and lower sides of each set of membrane bundles 4 are respectively fixedly connected to the upper mounting block 5 and the lower mounting block 6. The side walls of each set of mounting frames 3 are fixedly connected to multiple fixing blocks 7. The top of the fixing block 7 is provided with a first mounting groove corresponding to the upper mounting block 5, and the bottom of the first mounting groove is provided with a plurality of fixing blocks 7. An opening corresponding to the lower mounting block 6 is provided, and a second mounting groove corresponding to the lower mounting block 6 is provided on the top of the support seat 1. The installation of the membrane bundle 4 is completed by passing the lower mounting block 6 through the opening at the bottom of the first mounting groove, installing the lower mounting block 6 on the support seat 1, and installing the upper mounting block 5 in the first mounting groove. The top of the support seat 1 is rotatably connected to two threaded rods 8 through waterproof bearings, and the side wall of the mounting frame 3 is provided with threaded holes corresponding to the threaded rods 8. A cavity is provided in the support seat 1, and a drive assembly 9 is provided in the cavity.

[0014] The left and right sides of the two sets of mounting frames 3 are connected with limiting sliders 10, and the opposite sides of the two support plates 2 are provided with limiting sliding grooves corresponding to the limiting sliders 10, which can facilitate the position limiting of the two sets of mounting frames 3.

[0015] The driving assembly 9 includes a dual-axis motor 91 fixedly connected to the cavity, and the two output ends of the dual-axis motor 91 are fixedly connected to the driving rod 92 through a coupling. The other end of the driving rod 92 is fixedly connected to the first bevel gear 93. The bottom end of the threaded rod 8 extends into the cavity and is fixedly connected to the second bevel gear 94. The second bevel gear 94 is meshed with the first bevel gear 93. By using the dual-axis motor 91 to drive the two driving rods 92 to rotate, the driving rod 92 drives the first bevel gear 93 to rotate, the first bevel gear 93 drives the two second bevel gears 94 to rotate, and the second bevel gear 94 drives the two threaded rods 8 to rotate. Because the two first bevel gears 93 and the two second bevel gears 94 are set, the two first bevel gears 93 rotate in the same direction, which can make the two second bevel gears 94 rotate in opposite directions. Therefore, the two threaded rods 8 rotate in opposite directions, causing one of the two sets of mounting frames 3 to move up and the other to move down, moving the blocked membrane bundle 4 up and the unused membrane bundle 4 down, so that the raw water can be continuously filtered, thereby improving the treatment efficiency of the raw water.

[0016] Two support cylinders 11 are fixedly connected in the cavity. Bearings are connected in the support cylinders 11, and the inner walls of the bearings are fixedly connected to the outer walls of the driving rod 92, which can conveniently improve the stability of the driving rod 92 during rotation.

[0017] Working principle of the present invention: The membrane bundle 4 is installed by passing the lower mounting block 6 through the opening at the bottom of the first mounting groove, installing the lower mounting block 6 on the support seat 1, and installing the upper mounting block 5 in the first mounting groove. The installation of the membrane bundle 4 is completed by using a dual-axis motor 91 to drive the two drive rods 92 to rotate, the drive rod 92 drives the first bevel gear 93 to rotate, the first bevel gear 93 drives the two second bevel gears 94 to rotate, and the second bevel gear 94 drives the two threaded rods 8 to rotate. Because the two first bevel gears 93 and the two second bevel gears 94 are set, the two first bevel gears 93 rotate in the same direction, which can make the two second bevel gears 94 rotate in opposite directions. Therefore, the two threaded rods 8 rotate in opposite directions, so that one of the two sets of mounting frames 3 moves up and the other moves down, the blocked membrane bundle 4 is moved up, and the unused membrane bundle 4 is moved down, so that the raw water can be continuously filtered, thereby improving the treatment efficiency of the raw water.
