Technical Field

[0001] The utility model relates to the technical field of sewage pretreatment, in particular to a sewage pretreatment structure for municipal water supply and drainage. Background Art

[0002] Municipal water supply and drainage projects refer to urban water supply and drainage systems (both municipal and building water supply and drainage). These systems use underground pipe networks to discharge urban sewage to treatment plants, where it is then treated and discharged into the sea. Currently, pre-treatment devices are often used to filter wastewater to prevent debris from clogging the underground pipe networks.

[0003] A search revealed an existing patent (Announcement No. CN221513773U) that discloses a municipal sewage pretreatment structure, comprising a treatment tank and a filter tank. The key technical features are: a horizontal partition is provided within the treatment tank, two filter tanks are arranged on the horizontal partition, a first matrix of filter holes is formed on the bottom surface of the filter tank, and a second matrix of filter holes is formed on the horizontal partition, communicating with the first matrix of filter holes. Horizontal push-pull cylinders are fixed to the left and right side walls of the treatment tank, with their rods connected and fixed to the outer wall of the filter tank. Removable water inlet pipes are provided on the upper portions of the left and right side walls of the treatment tank, with the inner ends of the movable water inlet pipes inserted into the upper side walls of the filter tank. A hollow cleaning port is provided on the lower portion of the rear side wall of the filter tank, and the filter tank is provided with a longitudinal insert corresponding to the hollow cleaning port. The rear side wall of the treatment tank is provided with a clearance opening corresponding to the hollow cleaning port. This structure eliminates the need for manual lifting or the use of additional lifting equipment to lift the filter assembly, saving time and effort when cleaning the filtered material while ensuring the continuity of the pretreatment process.

The medicine inside the medicine box 6 is sprayed into the sewage through the nozzle 7 to disinfect the sewage. When spraying water, the screw 4 can be controlled to rotate by the first servo motor 3, so as to drive the medicine box 6 to slide along the frame 2 through the connecting block 5 to spray medicine at different positions.

[0031] In this embodiment, two groups of baffles 8 are symmetrically arranged with respect to the nozzle 7 and are parallel to each other. The length of the two groups of baffles 8 is consistent with the length of the frame 2. The baffles 8 can prevent the medicine from spraying everywhere and play a limiting role.

[0032] In this embodiment, the connecting rod 13 and the winding rod 10 are parallel to each other, and the pull rope 11, the connecting rod 13 and the winding rod 10 are all arranged vertically. The second servo motor 9 is turned on to control the winding rod 10 to rotate. When the winding rod 10 rotates, the pull rope 11 can be wound up.

The baffle 8 can prevent the medicine from spraying everywhere and play a limiting effect. Then turn on the second servo motor 9 to control the winding rod 10 to rotate. When the winding rod 10 rotates, the pull rope 11 can be reeled in. When the pull rope 11 is reeled in, an upward pulling force can be applied to the connecting rod 13, so that the connecting rod 13 drives the salvage plate 15 to rise, so as to salvage the debris in the sewage.
