Description

Technical Field

[0001] This invention relates to the field of sewage lifting equipment technology, specifically to a sewage lifting equipment with anti-clogging function. Background Technology

[0002] Currently, sewage lifting stations are the latest equipment to replace the "one pit, two pumps" method for discharging underground sewage, completely solving the historical problems of easy clogging and difficult cleaning associated with the "one pit, two pumps" method. They are applicable to sewage discharge sites in the basements of various buildings. Chinese patent application number 202221890641.5 discloses "an anti-clogging sewage lifting station, comprising a main body, a top seat structure, a connecting shaft, a guide hinge layer, a storage tank, and an outlet pipe. The top seat structure is fixedly connected to the top of the main body, the connecting shaft is embedded inside the main body, the guide hinge layer and the connecting shaft are fixedly connected, the storage tank is fixedly connected to the outside of the main body, and the outlet pipe is fixedly connected to the outside of the bottom end of the main body. The top seat structure includes an inlet pipe, an outlet pipe, a docking shaft, and a conveying hinge. While sewage is being discharged, if impurities accumulate inside the main body, the connecting shaft and docking shaft drive the guide hinge layer on its surface to rotate. At this time, the rotating guide hinge layer conveys the docking impurities inside the main body downwards and discharges them. Simultaneously, it breaks and separates some easily entangled impurities. The docking shaft and connecting shaft can also rotate in opposite directions."

[0003] Existing technology only addresses the issue that debris remains inside the sealed box and is difficult to remove, requiring manual cleaning. Furthermore, as debris accumulates, it can clog the debris separator, affecting water pump intake. This results in poor anti-clogging and debris removal performance. During the use of the lifter, wastewater typically contains a large amount of dirt. If only the dirt in the wastewater is separated and filtered without further treatment, the efficiency of subsequent wastewater flow will be affected over time, potentially leading to blockages that require manual intervention. When blockages occur, the system cannot continue to operate until the blockages are cleared, which is neither quick nor convenient, reducing efficiency during use. Summary of the Invention

[0039] The switching sealing mechanism 7 also includes a small electric push rod 701 and a mounting recess 704. The mounting recess 704 is located at the bottom left side of the inner cavity of the commonly used lifting channel 301. The small electric push rod 701 is mounted on the top right side of the inner cavity of the mounting recess 704 via a hinge.

[0040] The abnormal start mechanism 6 also includes a moving block 601, a mounting spring 602, a touch switch 603, and a contraction airbag 605. The contraction airbag 605 is glued to the top of the inner cavity of the movable recess 604. The moving block 601 is bolted to the bottom of the contraction airbag 605. Several ball bearings are movably mounted around the outside of the moving block 601. The touch switch 603 is bolted to the bottom of the inner cavity of the movable recess 604. The mounting spring 602 is bolted to the bottom of the moving block 601. A compression block is bolted to the bottom of the moving block 601. The touch switch 603 is electrically connected to the small electric push rod 701 and the small electric telescopic rod 504 on the right side, and the control circuit of the small electric telescopic rod 504 on the right side is reversed.

[0041] Working Principle: When lifting, the small electric telescopic rod 504 on the right side is activated first, causing the movable mounting block 503 to move downwards. This moves the movable guide block 502 downwards, bringing its bottom end into contact with the top of the connecting guide ring 501. This energizes the surrounding electromagnetic blocks 406, generating magnetism, which in turn magnetizes the surrounding metal guide rings. Simultaneously, the single-phase motor 401 is activated, driving the rotating ring frame 404 to rotate via the rotating rod 402. This, in turn, rotates the permanent magnet ring 405. Due to the magnetic attraction between the permanent magnet ring 405 and the metal guide rings, the stabilizing slip ring 407 rotates within the stabilizing ring groove 408. The stabilizing slip ring 407 then rotates the mounting ring 302, which in turn rotates the lifting screw 303. The lifting screw 303 also avoids... To prevent clogging during the later stages of sewage lifting, the rotating rod 307 drives the crushing blade head 306 to rotate. During lifting, the separation filter plate 304 separates and lifts solid dirt from the sewage, and the crushing blade head 306 crushes the accumulated solid dirt. The rotating movable brush strip 305 cleans and scrapes the bottom of the separation filter plate 304, increasing the efficiency of sewage lifting. It can also crush the solid dirt accumulated after separation. Once the solid dirt is crushed, the sewage can continue to be lifted and transported. This avoids the accumulation of a large amount of solid dirt after prolonged separation and filtration during the later stages of lifting, which could cause clogging during the later stages of sewage lifting and prevent the sewage from being lifted again.

[0042] Furthermore, when the commonly used lifting channel 301 can no longer lift, but sewage is still being transported, the water pressure inside the double-hole conveying channel 10 will increase, causing liquid water to be transported into the contraction airbag 605. This causes the contraction airbag 605 to expand, pushing the moving block 601 downwards. This causes the squeezing block to contact the touch switch 603. Simultaneously, the touch switch 603 closes the small electric telescopic rod 504 on the right side, and activates the small electric push rod 701 to push the lever 702 to the lower left end. Using the hinge as the axis, it drives the movable blocking plate 703 to move towards the side of the commonly used lifting channel 301, so that the movable blocking plate 703 contacts and seals the bottom end of the commonly used lifting channel 301. This will cause the interior of the double-hole conveying channel 10 to be through-flow. In the open state, the small electric telescopic rod 504 on the left is activated, which moves the movable guide block 502 on the left downward to contact the connecting guide ring 501 on the left. This energizes the electromagnetic block 406 on the left, generating magnetism and creating a magnetic attraction between it and the permanent magnet ring 405. This causes the lifting screw 303 on the left to rotate and perform the lifting operation. The spare lifting channel 308 can increase the stability of the sewage during the lifting process and the efficiency of the sewage lifting. If one of the lifting channels malfunctions, the spare lifting channel will be used immediately to lift the sewage, preventing the need for maintenance and delays caused by the failure of one of the lifting channels during use.
