Description

Technical Field

[0001] This utility model relates to the field of filter membrane frames, and more particularly to a movable and modular filter membrane frame. Background Technology

[0002] In the environmental wastewater treatment industry, MBR membrane bioreactors have been widely used due to their excellent membrane separation and retention capabilities. The core component is the MBR filter membrane, and among the MBR filter membrane series products, the MBR flat sheet filter membrane has the best overall performance. N MBR flat sheet filter membranes must be assembled in a rectangular support to be used. In the industry, this rectangular support is collectively referred to as a "membrane support", and the combination of it and the MBR flat sheet filter membrane is called a "membrane module".

[0003] Chinese patent CN215102253U discloses a movable, modular filter membrane frame for wastewater treatment. It includes a rectangular water collection pipe, a rectangular lower support, and a rectangular aeration pipe. The rectangular water collection pipe is detachably connected to the top of four supporting mechanisms, while the rectangular lower support and the rectangular aeration pipe are fixed to the bottom of the four supporting mechanisms. For transport, the second internal threaded sleeve is first removed, then the rectangular water collection pipe is taken off. The first internal threaded sleeve is then rotated until it is detached from the column, and the column is swung. The column swings along the connecting plate to a horizontal position and rotates according to the other columns, ensuring that the four columns do not interfere with each other. When the column is rotated to a horizontal position, the second screw on it is vertical. The mounting plate on the rectangular water collection pipe is then fitted onto the four second screws. At this point, the frame occupies relatively little space and is easy to transport. However, it uses a large number of threads and threaded sleeves for connection, which can easily cause the threaded sleeves to loosen over time, affecting the stability of use. Assembly is also time-consuming, and the spacing between the filter membranes cannot be adjusted, failing to meet the needs of different wastewater filtration applications.

[0004] Therefore, it is necessary to provide a movable, modular filter membrane holder to solve the above-mentioned technical problems. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the movable and modular filter membrane holder provided by this utility model; Figure 2 A half-sectional structural diagram of the positioning and locking mechanism provided by this utility model; Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. The movable assembly filter membrane frame includes an upper frame 7, a lower frame 5, casters 4 located at the bottom of the lower frame 5, and four support rods 2 arranged in a rectangle. The support rods 2 are connected to the upper frame 7 and the lower frame 5 through a positioning locking mechanism 1.

[0030] The positioning and locking mechanism 1 includes a positioning structure and a locking structure. The positioning structure includes two oblique fixing pins 17. The oblique fixing pins 17 are set on both sides of the groove 19. The groove 19 is symmetrically set on both sides of the outer surface of the support rod 2. The support rod 2 is snapped into the positioning hole 11. The positioning hole 11 is respectively set at the corner of the upper frame 7 and the lower frame 5. The locking structure is used to fix the two oblique fixing pins 17.

[0031] Positioning plates are provided on both sides of the support rod 2 to limit the assembly position of the upper frame 7 and the lower frame 5, which can limit the assembly of the upper frame 7 and the lower frame 5.

[0032] A reset spring 16 is provided on one side surface of the groove 19. One end of the reset spring 16 is connected to the inclined fixing pin 17, which enables the inclined fixing pin 17 to be reset and moved.

[0033] The locking structure includes a threaded hole 13, which is located at the end of the support rod 2. An adjusting bolt 12 is located in the threaded hole 13. A main conical block 14 is located at the end of the adjusting bolt 12. The main conical block 14 fits against a secondary conical block 15. The secondary conical block 15 is located at one end of a crossbar 18. The crossbar 18 is located on one side surface of the inclined fixing pin 17, which can lock and fix the two inclined fixing pins 17.

[0034] Adjustable fixing feet 3 are provided on both sides of the lower frame 5 to position the device.

[0035] The working principle of the movable, modular filter membrane holder provided by this utility model is as follows:

[0036] During assembly, the support rod 2 is first inserted into the positioning holes 11 in the upper frame 7 and the lower frame 5. When the oblique fixing pin 17 enters the positioning hole 11, the oblique fixing pin 17 moves into the groove 19 and compresses the return spring 16. When the oblique fixing pin 17 moves out of the positioning hole 11, the upper frame 7 and the lower frame 5 are respectively attached to the positioning plate. At this time, the return spring 16 drives the oblique fixing pin 17 to move back to its original position. The oblique fixing pin 17 moves out of the groove 19 and positions the upper frame 7 and the lower frame 5. Then, the adjusting bolt 12 is rotated, and the adjusting bolt 12 drives the main conical block 14 to move downward. When the main conical block 14 and the secondary conical block 15 are attached, the main conical block 14 fixes the secondary conical block 15, thereby providing auxiliary fixation for the oblique fixing pin 17.

[0037] Compared with related technologies, the movable and modular filter membrane holder provided by this utility model has the following advantages:

[0038] It can quickly assemble and position the upper frame 7 and the lower frame 5, and lock the assembled upper frame 7 and lower frame 5 to prevent them from coming loose and ensure their stability in use.

[0039] Second Embodiment

[0040] Please refer to the following: Figure 1 , Figure 4 and Figure 5 Based on the movable assembly filter membrane holder provided in the first embodiment of this application, the second embodiment of this application proposes another movable assembly filter membrane holder. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the movable assembly filter membrane frame provided in the second embodiment of this application differs in that, in the movable assembly filter membrane frame, multiple sets of adjustable upper membrane fixing frames 8 and lower membrane fixing frames 6 are respectively arranged in the upper frame 7 and the lower frame 5. Limiting sliders 75 are symmetrically arranged on both sides of the upper membrane fixing frames 8 and the lower membrane fixing frames 6. One end of the limiting slider 75 is arranged in the guide groove 72. The guide groove 72 is symmetrically arranged on both sides of the upper frame 7 and the lower frame 5, which ensures the guiding nature of the movement of the upper membrane fixing frames 8 and the lower membrane fixing frames 6.

[0042] One end of the limiting slider 75 is provided with an adjusting screw 74, which is located in the adjusting port 71. The adjusting port 71 is located on one side surface of the upper frame 7 and the lower frame 5 respectively, and the adjusting port 71 is connected to the guide groove 72, so that the adjusting screw 74 can be guided to move within the adjusting port 71.

First, the two ends of the biofiltration membrane are installed in the upper membrane fixing frame 8 and lower membrane fixing frame 6 respectively. Then, the upper membrane fixing frame 8 and lower membrane fixing frame 6 are pushed, and the upper membrane fixing frame 8 and lower membrane fixing frame 6 simultaneously drive the limiting slider 75 to move in the guide groove 72. The limiting slider 75 drives the adjusting screw 74 to move in the adjusting port 71. The spacing of multiple sets of upper membrane fixing frames 8 and lower membrane fixing frames 6 is adjusted in sequence. After the adjustment is completed, the adjusting screw 74 is locked and fixed by the threaded locking cap 73, thereby adjusting and fixing the spacing position of multiple sets of biofiltration membranes.

[0045] Both the upper film fixing frame 8 and the lower film fixing frame 6 have locking holes 77 on one side surface. Connecting rods 76 are installed in the locking holes 77. During assembly, the two ends of the connecting rods 76 are respectively inserted into the locking holes 77 of the upper film fixing frame 8 and the lower film fixing frame 6, which allows the upper film fixing frame 8 and the lower film fixing frame 6 to be spliced. Through the connection of the connecting rods 76, the upper film fixing frame 8 and the lower film fixing frame 6 can move simultaneously, which facilitates the adjustment of their spacing.
