Technical Field

[0001] This utility model relates to the field of filtration devices, and more particularly to a filtration device for water supply and drainage. Background Technology

[0002] With rapid industrialization and urbanization, water pollution has become increasingly serious. Large quantities of industrial wastewater, domestic sewage, and agricultural non-point source pollution are discharged, resulting in water bodies containing various impurities and pollutants, such as suspended solids, organic matter, heavy metal ions, and bacteria. This poses a significant challenge to the utilization and treatment of water resources.

[0003] Existing traditional filtration devices typically use simple filter screens or sieves to intercept larger particles of impurities, or use filters to filter out tiny suspended solids and fine impurities.

[0004] However, existing water supply and drainage filtration devices are usually built-in filters, which require the removal of multiple sets of bolts for disassembly. This makes it impossible to quickly disassemble and replace the filter, greatly increasing maintenance costs and workload. Therefore, a water supply and drainage filtration device is proposed to solve the above problems. Utility Model Content

A limiting groove is formed in the middle of the outer wall of the limiting frame.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the filter is slidably connected to the inner wall at the top of the filter box.

[0013] As a further description of the above technical solution:

[0014] The end of the diversion pipe is fixedly connected to the left outer wall of the filter box, and the top of the diversion pipe is fixedly connected to the end of the outlet pipe.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the flow limiting plate is slidably connected to the inner wall of the diversion pipe.

[0017] As a further description of the above technical solution:

[0018] One end of the limiting spring is fixedly connected to the top of the inner wall of the limiting frame, and the other end of the limiting spring is in contact with the middle of the top of the limiting rod.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a water supply and drainage filtration device, including an inlet pipe 1 for connecting to a water supply and drainage pipe, with water entering a branch pipe 2. The branch pipe 2 is fixedly connected to the end of the inlet pipe 1, and has two obliquely arranged sections for connecting to two sets of filter boxes 3 respectively. The filter boxes 3 are fixedly connected to the end of the branch pipe 2. The top protruding part of the filter box 3 can be disassembled with bolts for easy cleaning of water stains and impurities adhering to the inner wall after long-term use. A filter grid 5 is fixedly connected to the inner wall of the filter box 3. The filter grid 5 is provided in two bidirectional sets for filtering larger particles and impurities. The filter 6 is slidably connected to the inner wall of the filter grid 5. The filter 6 is a prior art filter that can use activated carbon particles wrapped with cotton material to filter fine suspended solids and impurities. The top and rear end of the filter box 3 is hinged to a cover plate 7. There are two sets of cover plates 7, which are connected at the hinge point to allow simultaneous opening of both sets of cover plates 7 to replace the filter 6. The top of the filter box 3 is provided with a limit component, and the outer wall of the filter 6 is slidably connected to the inner wall of the top of the filter box 3.

[0032] Reference Figures 1-3The left side wall of the filter box 3 is connected to the outlet pipe 4 via the diversion pipe 2. The outlet pipe 4 is used to connect to the other end of the water supply and drainage pipe to output the filtered water source. The top of the outer wall of the diversion pipe 2 is rotatably connected to the valve switch 8. The valve switch 8 is existing technology and is set with two sets on one side to close the filter box 3 on one side so that no water source enters. It also achieves the effect of preventing the water source from flowing back through the outlet diversion pipe 2. The bottom of the valve switch 8 is fixedly connected to the flow limiting plate 9. The flow limiting plate 9 is used to open or close the water inlet of the filter box 3 and can also achieve the effect of adjusting the water flow. The end of the diversion pipe 2 is fixedly connected to the left outer wall of the filter box 3, and the top of the diversion pipe 2 is fixedly connected to the end of the outlet pipe 4. The outer wall of the flow limiting plate 9 is slidably connected to the inner wall of the diversion pipe 2.

[0033] Reference Figures 2-4 The limiting assembly includes a limiting frame 10, which is used to keep the limiting rotating rod 13 moving stably up and down. The bottom of the limiting frame 10 is fixedly connected to the top center of the filter box 3. The top of the inner wall of the limiting frame 10 is elastically connected to a limiting rod 12 through a limiting spring 11. The limiting rod 12 is used to engage with the top of the cover plate 7, limiting the opening of the cover plate 7. The top of the limiting rod 12 is fixedly connected to the limiting rotating rod 13, which is used for external manual release of the limiting position, facilitating manual operation. A limiting groove 14 is opened in the middle of the outer wall of the limiting frame 10. Two sets of limiting grooves 14 are provided, one set for limiting the cover plate 7 and the other set for... When the cover plate 7 is released from its limiting position, one end of the limiting spring 11 is fixedly connected to the top of the inner wall of the limiting frame 10, and the other end of the limiting spring 11 is in contact with the middle of the top of the limiting rod 12. Through the opposing pressing force between the limiting spring 11 and the limiting frame 10, the limiting rod 12 is always locked onto the inner wall of the limiting groove 14 without being affected by external force. The outer wall of the limiting rod 12 is slidably connected to the inner wall of the limiting frame 10, and the middle of the outer wall of the limiting rod 12 is locked onto the inner wall of the limiting groove 14. The outer wall of the limiting rotating rod 13 is slidably connected to the top inner wall of the limiting frame 10, and the end of the limiting rod 12 is locked onto the top of the outer wall of the cover plate 7.

[0034] Working principle: When it is necessary to disassemble and replace the filter 6, manually pull up the limiting rod 13 to drive the limiting rod 12 out of the limiting groove 14 to release the limit. Then rotate the limiting rod 13 to drive the limiting rod 12 out of the top of the cover plate 7 to release the limit. At the same time, the limiting spring 11 will spring the limiting rod 12 back into another set of limiting grooves 14 to lock it. Then manually lift the cover plate 7 to take out the filter 6, realizing quick disassembly and installation of the filter 6, which improves the filtration quality and maintenance efficiency.

[0035] When replacing filter 6, manually rotate the two sets of valve switches 8 on one side. The valve switches 8 will cause the flow limiting plate 9 to close the diversion pipe 2 on one side. Manually pull up the limit rod 13 to cause the limit rod 12 to disengage from the limit groove 14 and release the limit. Then rotate the limit rod 13 to cause the limit rod 12 to disengage from the top of the cover plate 7 and release the limit. At the same time, the limit spring 11 will cause the limit rod 12 to spring back into the other set of limit grooves 14 and lock in place. Then manually lift the cover plate 7 to take out filter 6 for replacement. Then rotate the valve switch 8 on the same side to turn on the water source for filtration. Then rotate the valve switch 8 on the other side to close the diversion pipe 2. This allows filter 6 to be replaced without affecting the filtration operation, thus improving filtration efficiency.
