Description

Technical Field

[0001] The utility model relates to the field of municipal technology, in particular to a filtering device for municipal water supply and drainage. Background Art

[0002] Municipal facilities refer to various buildings, structures, equipment, etc. that provide paid or free public products and services within the scope of planning and construction. Various public infrastructure construction supporting urban life falls within the scope of municipal engineering. Water supply and drainage generally refers to urban water supply systems and drainage systems. In related technologies, municipal water supply and drainage operations will lay interconnected drainage pipes underground to divert sewage from various locations for overall treatment, and a filter will be installed in the drainage pipe. The filter is blocked in the inner cavity of the drainage pipe to intercept garbage carried in the sewage. The filtered sewage is discharged into the collection pool to await subsequent sewage cleaning operations.

[0003] The existing technical solution has the following defects: when the device is in use, the filter net is easily clogged. Due to the high content of powder in the wastewater of the cement production line, the powder easily clogs the holes on the surface of the filter net after long-term use, affecting the filter net's filtration of sewage and hindering the flow of sewage, which is not conducive to the normal operation of the device.

The hydraulic push rod drives the scrubbing brush to move through the guide rod to clean the sludge on the surface of the filter screen, while the spring pushes the scrubbing brush to adhere to the surface of the filter screen.

[0007] Preferably, a guide rod is installed at the bottom end of the hydraulic push rod, a connecting frame is inserted into the interior of the guide rod, a spring is sleeved on the outer side of the connecting frame, and a scrubbing brush is fixed to one side of the connecting frame.

[0008] Preferably, a sliding structure is formed between the spring and the guide rod, and the connecting frames are evenly distributed on one side of the scrub brush.

[0009] Preferably, the sludge discharge structure includes a motor, a stirring blade, a connecting shaft, a spiral blade, and a support frame. The motor is fixed to one side of the sludge discharge pipe, and one side of the motor is connected to the connecting shaft. The motor drives the connecting shaft to rotate, so that the stirring blade disperses the agglomerated sludge, and the spiral blade pushes the sludge to move, thereby facilitating the sludge discharge.

[0010] Preferably, a stirring blade is fixed to the outer side of the connecting shaft, a spiral blade is provided on one side of the stirring blade, and a support frame is sleeved on one side of the connecting shaft.
