Description

Technical Field

[0001] This utility model relates to the field of disc-type ceramic membrane technology, and in particular to a disc-type ceramic membrane that is easy to install and remove. Background Technology

[0002] The new ceramic membrane filtration technology uses disc-type ceramic membranes as filter elements. Through dynamic cross-flow filtration, it eliminates the concentration polarization layer on the membrane surface, significantly increases shear stress, and enhances the anti-fouling performance of the membrane surface, making it more conducive to the separation, concentration, and purification of high-concentration and high-viscosity materials.

[0003] In the production and installation of disc-type ceramic membranes, traditional installation methods involve assembling multiple components such as membranes, spacers, O-rings, and fastening screws into a filter element. This assembly comprises over 500 parts, making the process cumbersome. Each sealing point carries a risk of leakage, and the ceramic membranes are stacked one spacer on top of another on the main shaft. The large number of components often leads to microcracks and breakage of the ceramic membranes due to excessive stress. If problems occur during operation, the repair and disassembly work is extensive, requiring complete disassembly for inspection, replacement, and reinstallation, causing significant inconvenience, time-consuming, and labor-intensive work for on-site personnel, severely limiting the industrial application of disc-type ceramic membranes. Utility Model Content

[0004] The purpose of this utility model is to disclose a conveniently assembled disc-type ceramic membrane that allows for the rapid assembly of multiple components into a filter module unit. Multiple filter module units can then be assembled. This design is lightweight, quick to assemble, and allows for the rapid disassembly of faulty filter module units for on-site replacement with new ones. Damaged components can be repaired and reused offline, saving time and effort, significantly reducing the workload and maintenance time for on-site construction personnel, and improving work efficiency. Furthermore, the fewer components within the filter module unit reduce the probability of microcracks or breakage of the ceramic membrane, thus lowering costs.

[0005] To achieve the above objectives, this utility model provides a conveniently assembleable disc-type ceramic membrane, comprising a main shaft, several filter assembly units mounted on the main shaft, a fixed plate mounted at the head end of the main shaft, and a separable fixing ring mounted at the tail end of the main shaft; the several filter assembly units are held by the fixed plate and the separable fixing ring; each filter assembly unit includes a positioning plate, several spacers connected in sequence, and a ceramic membrane mounted on the spacers and pressed and fixed; the positioning plate and the spacers are connected, and both the positioning plate and the spacers are provided with through holes for the main shaft to pass through.

[0006] In some embodiments, the spacer ring has a boss, the boss has a plurality of openings and a plurality of mounting holes, the ceramic diaphragm is fitted on the boss with the openings facing the inner wall of the ceramic diaphragm, the spacer ring has a first groove on both the front and back, the first groove is provided with a first O-ring seal, and adjacent spacers are connected to each other by an elongated screw passing through the mounting holes so that the first O-ring seal and the ceramic diaphragm fit tightly together.

[0007] In some embodiments, the positioning disk has a plurality of mounting holes, the front side of the positioning disk has a plurality of positioning posts, the back side of the positioning disk has a second slot, the second slot has a second O-ring seal, and the positioning disk and the spacer are connected to each other by an extended screw passing through the mounting holes so that the second O-ring seal and the ceramic diaphragm fit tightly together.

[0008] In some embodiments, the fixed disk is fixedly connected to the head end of the spindle.

[0009] Compared with the prior art, the beneficial effects of this utility model are: multiple components are quickly assembled into a filter module unit, and then multiple filter module units are assembled. It is lightweight, quick to assemble, and allows for the rapid disassembly of faulty filter module units. New filter module units can be directly replaced on-site, and damaged components can be repaired and kept on-site.

[0016] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0017] like Figure 1-6 The illustrated easy-to-assemble disc-type ceramic membrane includes a main shaft 1, several filter assembly units 4 mounted on the main shaft 1, a fixed disk 2 mounted at the head end of the main shaft 1, and a separable fixing ring 3 mounted at the tail end of the main shaft 1.

[0018] The fixed disk 2 is fixedly connected to the first end of the main shaft 1, and the detachable fixing ring 3 is movably connected to the last end of the main shaft 1, facilitating the assembly and disassembly of the filter assembly units 4. The plurality of filter assembly units 4 are clamped by the fixed disk 2 and the detachable fixing ring 3, so that they can rotate synchronously with the main shaft 1.

[0019] During replacement, it is only necessary to first check which filter component unit 4 is leaking or has a microcrack during disassembly, remove the split fixing ring 3, and the problematic filter component unit 4 can be quickly disassembled. A new filter component unit 4 can be directly replaced on site. Damaged components can be repaired and kept on standby offline, saving time and effort, greatly reducing the workload of on-site construction personnel and maintenance time, and improving work efficiency.

[0020] The filter assembly unit 4 includes a positioning disk 7, ten spacers 5 connected in sequence, and a ceramic membrane 6 mounted on and fixed by compression on the spacers 5. The positioning disk 7 is connected to the spacers 5 and is located at the tail of the filter assembly unit 4. Multiple components can be quickly assembled into the filter assembly unit 4, and then multiple filter assembly units 4 can be assembled, resulting in a lightweight, fast assembly and disassembly efficiency. Furthermore, the fewer components within the filter assembly unit 4 reduces the probability of microcracks or breakage of the ceramic membrane 6, thus lowering costs.

[0021] The positioning disk 7 is provided with a through hole 70 for the main shaft 1 to pass through, and the spacer 5 is provided with a through hole 50 for the main shaft 1 to pass through.

[0022] The spacer ring 5 has a boss 51 on its front side, and the boss 51 has six openings 52 and six mounting holes 53. Three of the mounting holes 53 are used to connect with the adjacent spacer ring 5, and the other three mounting holes 53 are used to connect with another adjacent spacer ring 5 or the positioning plate 7.

[0023] The ceramic diaphragm 6 is annular and has six channels inside. The ceramic diaphragm 6 is fitted onto the boss 51, with openings 52 corresponding to the channels. The main shaft 1 has holes corresponding to the openings 52. Liquid filtered by the ceramic diaphragm 6 flows into the main shaft 1 through the channels, openings 52, and holes. This is prior art, therefore no structural diagram is provided.

[0024] The spacer ring 5 has a first groove 54 on both sides. The first groove 54 is provided with a first O-ring seal. Adjacent spacer rings 5 ​​are connected to each other by an extended screw (not shown) passing through the mounting hole 53 so that the first O-ring seal and the ceramic diaphragm 6 fit tightly together. This not only ensures the sealing performance, allowing liquid to enter the opening 52 only through the channel of the ceramic diaphragm 6, but also effectively protects the transmission of friction and torque between the first O-ring seal and the ceramic diaphragm 6.

[0025] The positioning disk 7 has a second slot 73 on its reverse side, and a second O-ring seal is provided in the second slot 73. The positioning disk 7 has three mounting holes 72. The positioning disk 7 and the spacer 5 are connected to each other by an extended screw passing through the mounting holes 72 and 53 to ensure that the second O-ring seal and the ceramic diaphragm 6 are tightly fitted. This not only ensures the sealing performance, allowing liquid to enter the opening 52 only through the channel of the ceramic diaphragm 6, but also effectively protects the transmission of friction and torque between the second O-ring seal and the ceramic diaphragm 6.

[0026] The positioning disk 7 has three positioning posts 71 on its front side. The positioning posts 71 are inserted into the mounting holes 53 of the spacer ring 5 at the first end of the adjacent filter component unit 4 to achieve positioning. The positioning post 71 of the positioning disk 7 at the last end is inserted into the split fixing ring 3. The three mounting holes 72 and the three positioning posts 71 are arranged alternately at intervals.

[0027] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
