Description

Spherical supports for microfilters

technical field

The utility model relates to the field of filters in which filter elements move during filtering operations, in particular to a spherical support device for a microfilter.

Microfilter is a screen filter device, mostly used for mechanical equipment for solid-liquid separation in the early stage of sewage treatment system.

The drum is attached with a filter screen. When the drum is placed in water to work, 2/5 of the filter screen is submerged in the water. The treated wastewater enters the drum along the axial direction and flows out through the screen. Impurities in the water are trapped on the drum for filtration. inside the net. When the impurity trapped on the screen is brought to the upper part by the drum, the backwash water outside the screen is washed into the sewage tank and flows out to realize the separation of solid and liquid phases. The backwash is controlled by a timer or a liquid level sensor. The filtered water is returned to the pool for recycling. The rotation of the microfiltration machine is driven by hydraulic power, and it operates continuously and automatically. Due to the working nature of the microfiltration machine, during the working process, waste water to be treated will continuously flow in from the front of the drum and filter out from both sides, so the water flow will continue to produce a certain amount of pressure on the drum. impact effect.
