Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane sewage treatment, in particular to an MBR membrane sewage treatment device which is easy to replace. Background Art

[0002] MBR, or membrane bioreactor, is a new type of sewage treatment process that combines membrane separation technology with biological treatment technology. In the MBR system, sewage first enters the bioreactor, where organic matter is degraded and converted by the action of microorganisms. Then, the mixed liquid is filtered through the MBR membrane assembly. The pore size of the membrane is very small, which can effectively intercept microorganisms and suspended matter, making the treated water clear and transparent. The filtering effect of the MBR membrane replaces the sedimentation effect of the traditional secondary sedimentation tank, thereby realizing mud-water separation and improving the effluent water quality.

[0003] The MBR membrane supports used in the industry require the installation of air inlet and outlet pipes for aeration, as well as water outlet pipes, etc. Therefore, the supports are heavy and complex, and use a large amount of stainless steel, which significantly increases the cost.

The utility model utilizes the support body to connect the water collecting pipe and the aeration pipe, making the MBR device structure more compact and the installation of the MBR membrane assembly more convenient and reliable; the symmetrically arranged air inlet pipes can realize alternating aeration, make the MBR membrane wires shake evenly, and reduce some energy consumption.

[0005] In view of the above problems, existing patents have provided solutions. However, when the MBR membrane is used for sewage filtration, periodic maintenance is required or the MBR membrane needs to be replaced or cleaned in time when the filter tube is blocked. The replacement or disassembly is troublesome and inconvenient to use.

[0006] Therefore, an MBR membrane sewage treatment equipment which is easy to replace is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] An MBR membrane wastewater treatment device that is easy to replace includes a frame 1, a membrane frame 2 is movably connected to the inside of the frame 1, a mounting pipe 3 is bolted to the top of the membrane frame 2, an MBR membrane 4 is installed on the inside of the membrane frame 2, an output pipe 5 is installed on the top of the frame 1, a connecting pipe 6 is provided on the outside of the mounting pipe 3, a quick-release assembly 7 is provided on the outside of the connecting pipe 6, an up-flow pipe 8 is bolted to the outside of the connecting pipe 6 on the side close to the output pipe 5, and a water flow assembly 9 is provided on the inside of the connecting pipe 6;

[0030] The quick-release assembly 7 includes an outer hoop 701 and a raised ring 702 fixedly connected to the outside of the connecting tube 6. A sealing gasket 703 is provided on the outside of the raised ring 702. The outside of the sealing gasket 703 contacts the outer hoop 701. A rubber ring 704 is provided between the two connecting tubes 6.

[0031] In this embodiment: a frame 1 is provided for supporting the structure, an MBR diaphragm 4 is provided for filtering the water passing through the inside, and a mounting pipe 3 connected to the MBR diaphragm 4 is connected to the output pipe 5. When the output pipe 5 is connected to the external pump equipment, a negative pressure is generated inside the connecting pipe 6, and water is drawn into the MBR diaphragm 4 and filtered out. The membrane frame 2 is used to flexibly assemble the MBR diaphragm 4 inside the frame 1. A quick-release assembly 7 is provided. When it is necessary to disconnect multiple membrane frames 2 and the mounting pipe 3 for replacement or maintenance, the outer hoop 701 can be opened, and the sealing gasket 703 and the rubber ring 704 can be removed to facilitate quick disassembly of a single group of membrane frames 2, the mounting pipe 3 and the MBR diaphragm 4. During installation, after the sealing gasket 703 and the rubber ring 704 are connected, the outer hoop 701 can be clamped on the outside of the raised ring 702 to complete the connection and installation of the structure.

[0032] Specifically, such as Figure 6 As shown, the water flow assembly 9 includes an inner frame 901, a tension spring 902 is bolted to the outer side of the inner frame 901, a baffle 903 is bolted to the side of the tension spring 902 away from the inner frame 901, a connecting rod 904 is bolted to the outer side of the inner frame 901, and a blocking frame 905 is bolted to the side of the connecting rod 904 away from the inner frame 901.

[0033] Specifically, such as Figure 6As shown, a side of the blocking frame 905 close to the blocking piece 903 and a side of the blocking piece 903 close to the blocking frame 905 are both bolted with a matching ring 906 , and a rubber ring 907 is provided between the two matching rings 906 .

[0034] Specifically, such as Figure 6 As shown, a limiting ring 908 is bolted to the inner wall of the connecting pipe 6 , and the limiting ring 908 is clamped to the inner frame 901 on one side close to the inner frame 901 .

[0035] In this embodiment: when liquid enters the interior of the connecting tube 6, the liquid under negative pressure will push the baffle 903 along the blocking frame 905. At this time, the tension spring 902 will be pressed and stretched, so there is a gap between the blocking frame 905 and the baffle 903 for the liquid to enter the interior of the ascending tube 8. The provided connecting rod 904 cooperates with the inner frame 901. When the water flow component 9 needs to be installed or disassembled, the inner frame 901 and the blocking frame 905 can be connected to remove the entire structure together. When liquid is not needed to pass through, the matching ring 906 and the internal rubber ring 907 can improve the sealing of the structure. When there is no liquid flowing, the tension spring 902 is reset to pull the structure to reset for subsequent operations.

[0036] Specifically, such as Figure 1 As shown, a plug-in frame 10 is bolted to the inner side of the frame 1 , and the inner side of the plug-in frame 10 is clamped to the membrane frame 2 .

[0037] Specifically, such as Figure 1 and Figure 3 As shown, a three-way valve 11 is installed at the bottom of the output pipe 5, and the bottom of the three-way valve 11 and the upward pipe 8 are connected through a flange.

[0038] In this embodiment, by providing a plug-in rack 10, the membrane rack 2 can be quickly connected or disassembled. The three-way valve 11 can be quickly switched to the other side when the membrane rack 2, the mounting pipe 3 and the MBR diaphragm 4 on one side cannot be used, so that maintenance and disassembly can be carried out during operation.

[0039] Specifically, such as Figure 5 As shown, the outer hoop 701 is made of two metal arc-shaped half hoops, and a buckle 12 and a hook are respectively installed on the outside of the half hoops. The buckle 12 and the hook are clamped together, and the two half hoops are rotatably connected through a hinge joint.

[0040] Specifically, such as Figure 6 As shown, a pull ring 14 is bolted to the outer side of the blocking frame 905, and the outer side of the pull ring 14 is provided with anti-slip grooves.

[0041] In this embodiment: by setting up two arc-shaped half-hoops supported by the buckle 12 and the hook, when the two half-hoops rotate along the intersecting page, the structure can be quickly disassembled or installed by the buckle 12 or the hook, and the pull ring 14 can facilitate the entire disassembly of the water flow component 9 when disassembling it.

[0042] Working principle: When water is treated through the MBR membrane, when the output pipe 5 is connected to the external pump equipment, negative pressure is generated inside the connecting pipe 6, and water is pumped into the MBR membrane 4 and filtered out. The membrane frame 2 is used to flexibly assemble the MBR membrane 4 inside the frame 1. The quick-release component 7, when it is necessary to disconnect multiple membrane frames 2 and the installation pipe 3 for replacement or maintenance, the outer hoop 701 can be opened through the buckle 12 and the hook, and the sealing gasket 703 and the rubber ring 704 can be removed to facilitate the rapid disassembly of the single group of membrane frames 2 and the installation pipe 3 and the MBR membrane 4. When installing, connect the sealing gasket 703 and the rubber ring 704. Then the outer hoop 701 can be clamped on the outside of the raised ring 702 to complete the connection and installation of the structure. When the liquid enters the connecting pipe 6, the negative pressure liquid will push the baffle 903 along the blocking frame 905. At this time, the tension spring 902 will be pressed and stretched, so there is a gap between the blocking frame 905 and the baffle 903 for the liquid to enter the interior of the ascending pipe 8. The provided connecting rod 904 cooperates with the inner frame 901. When the water flow component 9 needs to be installed or disassembled, the inner frame 901 and the blocking frame 905 can be connected to remove the entire structure together. When the membrane frame 2, installation pipe 3 and MBR diaphragm 4 on one side cannot be used, it can be quickly switched to the other side for use.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
