Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a water distribution frame unit. Background Technology

[0002] In the field of externally pressurized hollow fiber column membrane modules, membrane fibers are fixed to the water distribution frames at both ends of the hollow fiber column membrane module by resin casting. During the fiber loading process, a thin mesh is used to wrap the membrane fibers before they are inserted into the membrane shell to prevent them from collapsing. Casting is done horizontally and centrifugally. Without the thin mesh to wrap the membrane fibers, they would collapse and deviate during casting. This type of hollow fiber column membrane module, with the thin mesh fixing the membrane fibers during operation, can lead to incomplete cleaning during the cleaning process. Furthermore, the tightly adhering thin mesh can obstruct the removal of contaminants, affecting the cleaning effect and service life of the hollow fiber membrane module. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a water distribution frame unit, which includes two water distribution frames, an upper and a lower, and a central tube connecting the two water distribution frames. The water distribution frame includes an annular body that matches the central tube and a partition plate that is fixedly connected to the annular body. The partition plate extends radially along the outer ring of the annular body and is evenly distributed along the circumference of the outer ring of the annular body. The feature is that the partition plate is a partition plate with a clamping function, and plastic mesh is clamped between two corresponding partition plates of the upper and lower water distribution frames.

[0004] The further technical features of the utility model are: The separator is a U-shaped groove structure, wherein elastic clamps matching the mesh size of the plastic mesh are provided on both sides of the U-shaped groove.

[0005] The separator consists of a fixed clamping piece fixedly connected to the annular body and a movable clamping piece rotatably connected to the fixed clamping piece. The fixed clamping piece is provided with an elastic clamping body that matches the mesh size of the plastic mesh, and the movable clamping piece is provided with a fastening hole that matches the elastic clamping body at the corresponding position.

[0006] The separator consists of a fixed clamping piece fixedly connected to the annular body and a movable clamping piece rotatably connected to the fixed clamping piece. The movable clamping piece is provided with an elastic clamping body that matches the mesh size of the plastic mesh, and the fixed clamping piece is provided with a fastening hole that matches the elastic clamping body at the corresponding position.

[0007] The separator is a split structure, consisting of a fixed plate fixedly connected to the annular body and a movable plate that matches the fixed plate. The fixed plate has an elastic clamp that matches the mesh size of the plastic mesh on one side, and the movable plate has a corresponding fastening hole that matches the elastic clamp.

[0008] The separator is a split structure, consisting of a fixed plate fixedly connected to the annular body and a movable plate that matches the fixed plate. The movable plate has an elastic clamp that matches the mesh size of the plastic mesh on one side, and the fixed plate has a corresponding fastening hole that matches the elastic clamp.

[0009] A support frame is also provided on the central pipe between the upper and lower water distribution frames. The support frame includes a support frame body and a support arm fixedly connected to the support frame body. The number of support arms is the same as the number of partition plates of the water distribution frame. One side of each support arm is provided with an elastic clamp that matches the mesh size of the plastic mesh. Each support arm is also equipped with a clamping plate that matches the support arm. The clamping plate is also provided with a corresponding snap-fit ​​hole that matches the elastic clamp.

With the support of the plastic mesh, after the water distribution frame unit is installed into the membrane shell, the membrane fibers can be directly inserted between the separators for casting. There is no need for thin mesh to wrap the membrane fibers, and there will be no problem of membrane fiber collapse or deviation. Moreover, during the cleaning process, it is easy to remove dirt from the surface of the membrane fibers through the plastic mesh, achieving a good cleaning effect and extending the service life of the hollow fiber column membrane module.

Example 2

[0015] A water distribution frame unit is the same as other parts in Embodiment 1, except that the structure of the partition plate 12 in the water distribution frame is different, such as... Figure 3 The separator 12 shown consists of a fixed clamping piece 5 fixedly connected to the annular body 11, and a movable clamping piece 6 rotatably connected to the fixed clamping piece. The fixed clamping piece 5 is provided with an elastic clamping body 4 that matches the mesh size of the plastic mesh 3, and the movable clamping piece 6 is provided with a corresponding fastening hole 7 that matches the elastic clamping body 4.

Example 3

[0016] A water distribution frame unit is the same as other parts in Embodiment 1, except that the structure of the partition plate 12 in the water distribution frame 1 is different, such as... Figure 4 The partition plate 12 shown is a split structure, consisting of a fixed plate 8 fixedly connected to the annular body 11 of the water distribution frame and a movable plate 9 matching the fixed plate 8. One side of the fixed plate 8 is provided with an elastic clamp 4 matching the mesh size of the plastic mesh 3, and the movable plate 9 has corresponding fastening holes 7 matching the elastic clamp 4.

Each support arm 14 is also equipped with a clamping plate 15, and the clamping plate 15 is also provided with corresponding fastening holes 7 that match the elastic clamp 4. Since the support frame 10 is also provided on the central tube 3 between the upper and lower water distribution frames 1, this effectively prevents the membrane fibers from becoming tangled in the middle. In practical applications, the support frame 10 can also be configured by placing the elastic clamp 4 on the clamping plate 15, with corresponding fastening holes 7 on the support arms 14.

[0018] In this invention, since the separator 12 is a separator with a clamping function, plastic mesh 3 is clamped between the two corresponding separators 12 of the upper and lower water distribution frames 1. With the support of plastic mesh 3, after the water distribution frame unit is installed into the membrane shell, the membrane fibers can be directly inserted between the separators 12 for pouring.
