Description

Technical Field

[0001] This utility model relates to the field of sewage filtration technology, and in particular to a filtration structure for domestic sewage treatment. Background Technology

[0002] Kitchen sinks are one of the places that generate the most wastewater in daily life. These sinks accumulate various vegetable scraps, rice grains, mud, and other debris. If this debris is directly discharged into the sewer, it will inevitably cause blockages over time. Existing kitchen sinks often have a removable filter basket installed at the bottom to filter and trap this debris.

[0003] During use, vegetable washing sinks often accumulate a large amount of vegetable scraps and other residue. When these scraps fill the filter basket, drainage efficiency drops significantly. Sufficient time must be waited for the wastewater to drain completely before the filter basket can be cleaned, which disrupts the entire washing process. In such situations, users often simply lift the filter basket upwards to quickly remove the residue before replacing it. However, this process negates the purpose of intercepting some residue, creating a potential blockage in the sewer system. Therefore, this paper proposes an improved filtration structure for domestic wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a filtration structure for domestic sewage treatment to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a filter structure for treating domestic sewage, including a filter basket and a frame. The filter basket is inserted into the frame, a lifting rod is provided inside the filter basket, a first magnetic block is fixedly connected to the bottom surface of the filter basket, and a first water outlet is provided on the filter basket.

[0007] A mounting plate is fixedly connected to the bottom of the frame, and a plurality of multi-stage damping telescopic rods evenly arranged in a circle within the frame are fixedly connected to the mounting plate. A tray is fixedly connected to the top of each multi-stage damping telescopic rod, and a second magnetic block is provided inside the tray. A second water outlet is provided on the tray.

[0008] Preferably, in any of the above embodiments, the top of both the filter basket and the frame is fixedly connected with a placement ring, and the lifting rod adopts a U-shaped structure.

[0009] Preferably, in any of the above embodiments, the two ends of the lifting rod are rotatably connected inside the filter basket, and the first magnetic block adopts a ring structure.

[0010] The above technical solution employs the following: A filter basket is placed at the drain of the kitchen sink to filter wastewater discharged from the sink, preventing vegetable scraps and other residue from clogging the drain pipe. A sleeve is fitted onto the outside of the filter basket, providing a platform for mounting plates and other structures. A placement ring is provided at the top of the filter basket and sleeve, which can be secured at the drain of the sink to prevent the filter basket and sleeve from falling into the drain pipe. A lifting rod allows the user to easily lift and remove the filter basket from the sink. The lifting rod is rotatably connected inside the filter basket, allowing for easy rotation when needed.

[0011] Preferably, in any of the above embodiments, the filter basket has a first water outlet hole on both its bottom and side surfaces, and the mounting plate adopts a ring structure.

[0012] Preferably, in any of the above embodiments, the multi-stage damping telescopic rod includes a primary rod, a secondary rod inserted into the primary rod, a final rod inserted into the secondary rod, and damping blocks disposed at the inner ends of the secondary rod and the final rod.

[0013] The above technical solution employs the following: A first magnetic block is installed inside the filter basket, which, in conjunction with a second magnetic block, connects the tray to the filter basket. A first water outlet is provided on the filter basket to drain domestic wastewater from the sink. First water outlets are also provided on the side and bottom of the filter basket to facilitate rapid drainage of wastewater from these surfaces. The mounting plate provides an installation platform for the multi-stage damping telescopic rods. Several multi-stage damping telescopic rods are evenly arranged circumferentially on the mounting plate. These rods can intercept vegetable scraps and other debris, preventing them from falling into the drain pipe. Damping blocks are installed inside the multi-stage damping telescopic rods to facilitate locking their length after adjustment.

[0014] Preferably, in any of the above solutions, the damping block is made of rubber, and the inner diameter of the tray is larger than the outer diameter of the filter basket.

[0015] Preferably, in any of the above schemes, the second magnetic block adopts a ring structure, and the second water outlet is set in a one-to-one correspondence with the first water outlet at the bottom of the filter basket.

[0016] The above technical solution involves installing a tray at the top of the multi-stage damping telescopic rod. This tray provides a platform for the second magnetic block and also space for the filter basket. The second magnetic block works in conjunction with the first magnetic block to connect the filter basket to the tray, maintaining this connection even without external force. A second water outlet is provided on the tray, allowing wastewater passing through the filter basket to drain through, ensuring proper drainage.

In use, the frame 2 is placed in the drain of the sink, and then the filter basket 1 is placed inside the frame 2. The first magnetic block 4 and the second magnetic block 9 attract each other, connecting the filter basket 1 to the tray 8. During drainage, wastewater is discharged through the first outlet hole 5 and the second outlet hole 10. When the filter basket 1 is filled with vegetable scraps or other residue, the filter basket 1 is lifted upwards by holding the lifting rod 3. During this process, the first magnetic block 4 at the bottom of the filter basket 1, in conjunction with the second magnetic block 9, pulls the tray 8 upwards, and the multi-stage damping telescopic rod 7 gradually extends. When the multi-stage damping telescopic rod 7 is stretched to its maximum length, the tray 8 is exposed above the drain of the sink, and wastewater continues to flow out between the multi-stage damping telescopic rods 7. Vegetable scraps and other residue are blocked by the multi-stage damping telescopic rods 7. The filtration effect is maintained even during the cleaning of filter basket 1, without having to wait for the sewage to drain completely, making it more convenient to use.
