Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage technology, specifically a water supply and drainage filtration device. Background Technology

[0002] In the operation of water supply and drainage systems, in order to ensure that water quality meets standards, it is usually necessary to install filtration devices in the pipeline to filter the water flow. Most common water supply and drainage filtration devices rely on a single filtration pipeline to achieve the filtration function. Their core components include filter elements for intercepting impurities and the pipeline body that carries the filter elements. Through the contact between the filter elements and the water flow, the removal of pollutants such as suspended impurities and particulate matter in the water is achieved. They are widely used in scenarios such as residential water supply and industrial wastewater pretreatment, and are important equipment to ensure the stable operation of water supply and drainage systems and water quality safety.

[0003] However, existing water supply and drainage filtration devices have obvious defects in actual use. Since most devices adopt a single filter pipeline design, when the filter element needs to be cleaned or replaced, the operation of the entire water supply and drainage system must be stopped. This will lead to water interruption and seriously affect the normal domestic water use of residents or the continuity of industrial production. It is difficult to meet the requirements of system stability and ease of operation in practical applications. Therefore, we propose a water supply and drainage filtration device.

[0008] Preferably, the first pipeline is disconnected in the middle, and the two ends of the first pipeline are a fitting pipe and a filter pipe, respectively. The fitting pipe is welded to one side wall of the distribution box. The fitting pipe has a telescopic cavity inside, and two concentrically distributed annular cylinders are provided on the shaft end of the corresponding opening side of the telescopic cavity.

[0016] 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.

[0017] Please see Figure 1-6 This utility model provides a technical solution; A water supply and drainage filtration device, comprising: The drain pipe body 1, motor 4, and motor 5 are provided at both ends of the drain pipe body 1. Motor 4 and motor 5 have the same structure. The quick-change assembly is located inside the drain pipe body 1. The two quick-change assemblies are symmetrically distributed and include a telescopic tube 2 and a filter cylinder 3. The telescopic tube 2 is slidably fitted inside the drain pipe body 1 and can communicate with the inside of the drain pipe body 1. The filter cylinder 3 is located inside the drain pipe body 1 and is attached to the shaft end of the telescopic tube 2. It is used to filter the water flowing inside the drain pipe body 1. The quick-change assembly can quickly replace the internal filter cylinder 3.

[0018] Furthermore, the drain pipe body 1 includes a first diversion box 6, a second diversion box 7, and a support frame 8. The bottoms of the first diversion box 6 and the second diversion box 7 are welded to both ends of the support frame 8. Both the first diversion box 6 and the second diversion box 7 are Y-shaped structures. The first diversion box 6 has a telescopic cavity 13 inside. The side wall of the first diversion box 6 has an inlet pipe 23. The drain pipe body 1 receives water through the inlet pipe 23. The direction of the water flow is controlled by the first motor 4, so that the water can flow to the first pipe 9 or the second pipe 10.

[0019] Furthermore, the side wall of the drain pipe body 1 is provided with two axially symmetrically distributed pipes 9 and 10. Pipes 9 and 10 have the same structure, and both ends of pipes 9 and 10 are connected to the interior of the distribution box 6 and the distribution box 7, respectively. One of pipes 9 and 10 is in working state and the other is in idle state. This facilitates the replacement of the filter cartridge 3 in the overall pipeline by switching the flow direction of the water inside the drain pipe through motors 4 and 5 without affecting the normal operation of the whole. After switching, the idle pipe can be used to replace the filter cartridge 3 inside, while the connected pipe performs normal filtration.

[0020] Furthermore, the middle of pipe 9 is disconnected, and the two ends of pipe 9 are respectively fitting pipe 11 and filter pipe 12. Fitting pipe 11 is welded to the side wall of distribution box 6. Fitting pipe 11 has a telescopic cavity 13 inside, and the telescopic cavity 13 has two concentrically distributed annular cylinders 15 at the shaft end corresponding to the opening side, and the annular cylinders 15 have sealing rings 16 on their sides.

[0021] Furthermore, the filter tube 12 has a cylindrical cavity 14 inside, and a flange is provided at the shaft end corresponding to the opening side of the filter tube 12.

[0022] Furthermore, the filter cartridge 3 slides against the inner wall of the cavity 14, allowing the filter cartridge 3 to effectively filter the flowing water.

[0023] Furthermore, a slider 17 is provided on one side of the telescopic tube 2, which slides in conjunction with the telescopic cavity 13. A flange 19 is provided on the other side of the telescopic tube 2, which is connected to the flange on the shaft end of the filter tube 12 by adapter bolts. A top cylinder 20 is provided on the end face of the flange 19, and the shaft end of the top cylinder 20 mates with the shaft end of the filter cylinder 3. Two concentric annular grooves 18 are provided on the side of the slider 17 corresponding to the flange 19. The annular grooves 18 mate with the annular cylinder 15, and the annular grooves 18 and the annular cylinder 15 form a curved seal. The side of the slider 17 corresponding to the flange 19 is in contact with the sealing ring 16. The first motor 4 and the second motor 5 rotate, controlling the output shaft 21. Rotation causes the flow divider 22 on the outside of the output shaft 21 to close both ends of the first pipe 9. At this time, the second pipe 10 is connected and performs water filtration. Inside the first pipe 9, the flange connection between the flange 19 and the corresponding open side of the filter pipe 12 can be disconnected. At this time, the telescopic pipe 2 can slide into the telescopic cavity 13. The filter cylinder 3 can then be pulled out from the cylinder cavity 14 for cleaning or replacement. After completion, the connection is restored, and the top cylinder 20 axially fixes the replaced filter cylinder 3 to prevent it from moving and ensure positional stability. At the same time, the curved sealing ring 16 formed by the annular groove 18 and the annular cylinder 15 effectively ensures the sealing of the pipeline.

[0024] Furthermore, motor 4 is fixedly connected to the top of the diversion box 6 by adapter screws, and the bottom of motor 4 is provided with an output shaft 21. The output shaft 21 is rotatably engaged with the telescopic cavity 13. The side wall of the output shaft 21 is provided with a diversion plate 22, which controls the direction of water flow.

Liquid inlet pipe 23: Located on the side wall of the distribution box 6, it is connected to the inside of the drain pipe body 1. It can introduce external water into the distribution box 6 to provide water to be filtered for the entire water supply and drainage filtration device.

[0026] Working Principle: The water supply and drainage filtration device is installed correctly according to the diagram. Water enters the distribution box 6 through the inlet pipe 23 on the drain pipe body 1. At this time, motor 4 controls its output shaft 21 to drive the distribution plate 22 to rotate, determining the water flow direction to either pipe 9 or pipe 10. One is always in working condition, and the other is always idle. If flowing to pipe 9, the water first passes through the connecting pipe 11 connected to the distribution box 6, enters the telescopic cavity 13 within the connecting pipe 11, and then flows through the telescopic pipe 2 into the cylindrical cavity 14 of the filter pipe 12. The filter cylinder 3, which slides within the cylindrical cavity 14, filters the water. After filtration, the water is discharged through the distribution box 7. When the filter cylinder 3 needs to be replaced, motors 4 and 5 synchronously control the distribution plate 22 to switch the water flow direction. With pipeline 2 (10) idle, pipeline 1 (9) is shut off from water flow, while pipeline 2 (10) is filled with water. The operator releases the bolts connecting flange 19 to the flange at the shaft end of filter tube 12, slides telescopic tube 2 into telescopic cavity 13, and then pulls out filter tube 3 from cylinder cavity 14 for replacement or cleaning. After replacement, telescopic tube 2 is reset, and filter tube 12 is reconnected through flange 19. Top cylinder 20 axially fixes filter tube 3, and at the same time, the annular cylinder 15 of pipe 11 and the annular groove 18 of telescopic tube 2 form a curved seal. The sealing ring 16 ensures pipeline sealing. At this time, the original pipeline can be switched back to operation as needed, or it can be used as preparation for the next cleaning or replacement of the internal filter components of pipeline 2 (10), reducing the impact of maintenance and repair downtime on normal filtration operation.
