Description

Technical Field

[0001] This utility model relates to the field of ceramic membranes, and in particular to a ceramic membrane filtration device. Background Technology

[0002] Ceramic membranes, also known as inorganic ceramic membranes, are asymmetric membranes formed from inorganic ceramic materials through a special process. They are divided into tubular ceramic membranes and flat-sheet ceramic membranes. Commercially available ceramic membranes typically have a three-layer structure (a porous support layer, a transition layer, and a separation layer), with pore sizes ranging from 0.8 nm to 1 μm, and filtration precision covering microfiltration, ultrafiltration, and nanofiltration levels. Ceramic membranes primarily use inorganic ceramic materials such as alumina, zirconium oxide, titanium dioxide, and silicon dioxide of different specifications as supports, and are manufactured through surface coating and high-temperature firing. They can be used for separation, concentration, and purification purposes.

[0003] A ceramic membrane filtration device is a water treatment device that uses ceramic membrane elements. A ceramic membrane is a separation membrane made by using inorganic ceramic materials as a support, through high-temperature firing and surface coating. It possesses many excellent properties such as good chemical stability, high mechanical strength, and high-temperature resistance, making it a current hot topic in the field of separation membranes.

[0004] Ceramic membrane filters are precision superfiltration and purification devices widely applicable in various fields. Their core component, the inorganic ceramic membrane, possesses excellent thermal and pore stability, exhibiting high strength, resistance to chemical corrosion, and good cleaning and regeneration performance, combining the advantages of both high-efficiency and precision filtration. Application number CN202321457699.5 discloses a ceramic membrane filtration device that, through the combined use of a cleaning plate and a pusher plate, can clean the ceramic membrane without additional manual labor. However, during use, this device cannot continue filtering wastewater or other substances while the ceramic membrane is being cleaned or replaced, resulting in a downtime during cleaning and reducing the filtration device's efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of a ceramic membrane filtration device provided by this utility model; Figure 2 for Figure 1 The diagram shows a frontal sectional view of the filter box section. Figure 3 for Figure 2 The diagram shows a partial structure of the partition plate. A ceramic membrane filtration device includes: a filter box 1, and a filter assembly 2 is provided on the inner side of the filter box 1.

[0022] The filter assembly 2 includes a pump 21 located on the left side of the filter box 1. The outlet of the pump 21 is connected to an inlet pipe 22. Two diversion pipes 23 are located at the bottom of the inlet pipe 22 and at the top of the filter box 1. Solenoid valves are provided on the front of the two diversion pipes 23.

[0023] In actual use, when one side of the ceramic membrane body 26 is removed for cleaning or replacement, the solenoid valve on its top can be closed, so that all the water drawn by the inlet pipe 22 enters the ceramic membrane body 26 that is in normal use on the other side. When both ceramic membrane bodies 26 are in normal use, the filtration speed can also be increased.

[0024] The bottom ends of the two diversion pipes 23 penetrate the top of the filter box 1 and extend into its interior. The bottom ends of the two diversion pipes 23 are provided with a first quick connector 24. The bottom of the two first quick connectors 24 is provided with a second quick connector 25. The bottom of the two second quick connectors 25 is provided with a ceramic membrane body 26.

[0025] The ceramic membrane body 26 can be sealed to the shunt tube 23 by using two quick connectors.

[0026] A partition plate 27 is vertically arranged at the bottom of the inner wall of the filter box 1. Support plates 28 are slidably arranged on the left and right sides of the partition plate 27 and inside the filter box 1. A docking flange 29 is provided on the top of each of the two support plates 28. The top of the two docking flanges 29 are respectively fixedly connected to the bottom of the two ceramic membrane bodies 26.

[0027] A sealed connection between the two ceramic membrane bodies 26 and the bottom hose 7 is achieved through the mating flange 29.

[0028] The bottom of the left and right sides of the partition plate 27 is provided with a two-way threaded screw 3 that can be rotatably arranged laterally. The two two-way threaded screws 3 are provided with threaded sleeves 4 that can move left and right along their length direction on their peripheral sides. The top of the two sets of threaded sleeves 4 are provided with connecting plates 5 that can be rotatably arranged. The top of the two sets of connecting plates 5 are respectively rotatably connected to the bottom of the two support plates 28.

[0029] When it is necessary to disassemble, clean and replace the ceramic membrane body 26 on one side, separate the two quick connectors, then turn the corresponding handwheel 6 to drive the bidirectional threaded screw 3 to rotate, thereby driving the threaded sleeve 4 on this side to move away from each other, thereby lowering the support plate 28. Finally, remove the docking flange 29 for replacement or cleaning. During cleaning or replacement, the ceramic membrane body 26 on the other side can still work normally.

[0030] The ends of the two bidirectional threaded screws 3 that are far apart from each other both penetrate the inner wall of the filter box 1 and extend to its left and right sides respectively. Each end of the two bidirectional threaded screws 3 that is far apart from each other is equipped with a handwheel 6.

[0031] Both connecting flanges 29 are equipped with flexible hoses 7 at their bottom ends, and the bottoms of the two flexible hoses 7 are connected to discharge pipes 8. A controller 9 is installed on the right side of the filter box 1.

[0032] The flexible hose 7 allows the support plate 28 to remain connected to the docking flange 29 even when it is lowered.

[0033] The working principle of the ceramic membrane filtration device provided by this utility model is as follows:

[0034] Step 1: During use, the sewage or other substances are drawn by the pump 21 and discharged into the two diversion pipes 23 through the inlet pipe 22. The diversion pipes 23 discharge the sewage or other substances into the ceramic membrane body 26 through quick connectors. After the substances are filtered by the ceramic membrane body 26, they are discharged through the bottom hose 7 and the discharge pipe 8, thus realizing the filtration work.

[0035] Step 2: When it is necessary to remove one side of the ceramic membrane body 26 for cleaning or replacement, the solenoid valve on its top can be closed, so that all the water drawn by the inlet pipe 22 enters the ceramic membrane body 26 that is in normal use on the other side. When both ceramic membrane bodies 26 are in normal use, the filtration speed can be increased. When disassembling, first separate the two quick connectors, then turn the corresponding side handwheel 6 to drive the bidirectional threaded screw 3 to rotate, thereby driving the threaded sleeve 4 on this side to move away from each other, thereby lowering the support plate 28. Finally, remove the docking flange 29 for replacement or cleaning.

[0036] Compared with related technologies, the ceramic membrane filtration device provided by this utility model has the following beneficial effects:

[0037] When it is necessary to remove one side of the ceramic membrane body 26 for cleaning or replacement, the solenoid valve on its top can be closed, so that all the water drawn by the inlet pipe 22 enters the ceramic membrane body 26 that is in normal use on the other side. During disassembly, first separate the two quick connectors, then turn the corresponding side handwheel 6 to drive the bidirectional threaded screw 3 to rotate, thereby driving the threaded sleeve 4 on this side to move away from each other, thereby lowering the support plate 28. Finally, remove the docking flange 29 for replacement or cleaning. The structure is simple and practical, and can maintain filtration during the maintenance of the ceramic membrane body 26, thereby ensuring the efficiency of the filtration device.
