Mechanical filter

Abstract

The invention discloses a mechanical filter, which comprises a cylinder body, a water inlet pipe, a water inlet, a water outlet pipe, a water outlet, a backwash inlet, a backwash outlet and a manhole. There is a water inlet pipe, one end of the water inlet pipe extends into the inside of the cylinder, the other end of the water inlet pipe is provided with a water inlet and a backwash outlet, the lower part of the outer wall of the cylinder is provided with a backwash inlet, and the inside of the cylinder is A filtering device is arranged below, and a water outlet pipe is arranged at the bottom of the cylinder, and a backwash inlet and a water outlet are arranged at one end of the water outlet pipe. The invention uses gas to flush from bottom to top, and it is easier to flush the filter layer without disturbing the water surface, thereby ensuring easier removal of oil stains and suspended matter, reducing recoil time, and ensuring recoil efficiency.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to a mechanical filter. Background technique [0002] Today's mechanical filters usually have a backwash function to flush the oil stains and suspended solids on the filter layer. The current mechanical filters usually install a motor on the top of the cylinder to drive the stirring shaft inside the cylinder to rotate. Suspended solids can be washed better, but in the specific operation of this recoil method, the water surface will be disturbed during stirring, causing oil stains and suspended solids to float down and not easily discharged, the recoil time will increase, and the recoil effect will become worse. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a mechanical filter. [0004] In order to achieve the above object, the present invention includes a cylinder body, a water inlet pipe, a water inlet, a water outlet pipe, a water ...

[0002] Today's mechanical filters usually have a backwash function to wash the oil stains and suspended solids on the filter layer. The current mechanical filter usually installs a motor on the top of the cylinder to drive the stirring shaft inside the cylinder to rotate, so that the oil stains and suspended solids Suspended solids can be washed better, but this recoil method will disturb the water surface when stirring, causing oil stains and suspended solids to float down and make it difficult to discharge. The recoil time will increase and the recoil effect will deteriorate.
