4results about How to "Backwash thoroughly" patented technology

The utility model discloses an integrated water purifier for surface water treatment, which comprises a water purifier, the water purifier comprises a water purification tank, a reactor is arranged on the water purification tank, a filter tank is fixedly arranged in the water purification tank, a honeycomb filler layer is arranged at the top of the filter tank, the filter tank is communicated with the reactor, and an anthracite filter layer and a quartz sand filter layer are arranged at the bottom of the water purification tank. A back flushing pipe is arranged below the quartz sand filter layer, one side of the back flushing pipe is communicated with a water outlet pipe and a driving pipe, the driving pipe is provided with a flow rate adjusting device and a water pump, sewage in the reactor reacts with a flocculating agent and then enters the filter box, and large particles in the sewage enter the filter box under the action of the honeycomb filler layer. Filtered water is further filtered by the quartz sand filter layer and the anthracite filter layer and then is discharged through the backwashing pipe and the water outlet pipe, siphon backwashing is changed into a water pump, backwashing strength is high, backwashing is thorough and clean, and the filter effect is good.

This utility model relates to the field of wastewater treatment equipment, and more particularly to an anti-clogging multi-media filter suitable for high-viscosity, high-turbidity wastewater. It includes a filter tank, an upper inlet pipe, a lower connecting pipe, a support column, a shaking screening mechanism, and a tapping cleaning mechanism. The upper inlet pipe is fixedly connected to the upper surface of the filter tank. This utility model incorporates a shaking screening mechanism and a tapping cleaning mechanism on top of a conventional filtration and backwashing valve system. The shaking screening mechanism utilizes mechanical vibration to effectively break up stubborn contaminant layers. The tapping cleaning mechanism uses water-driven tapping plates to pre-disperse contaminants during filtration and enhance turbulence during backwashing. This forms a multi-level cleaning method combining hydraulic flushing with mechanical vibration and tapping. Compared to traditional filters, its backwashing is more thorough, effectively solving the clogging problem of high-viscosity, high-turbidity wastewater filtration, and improving the operational stability of the equipment and the service life of the filter media.

The utility model discloses a kind of efficient backwash walnut shell filters, including filter, the filter is provided with oil drain pipe, first pipeline and second pipeline, the oil drain pipe is welded in filter top side, the first pipeline is welded on filter outside top, first pipeline outer end is welded with first docking tee, the left end of first docking tee is connected with water inlet electric valve by flange, the right end of first docking tee is connected with backwash outlet electric valve by flange, the second pipeline is connected in filter bottom opening by flange, emptying and second docking tee are provided on second pipeline, the emptying is welded in second pipeline middle section, the second docking tee is welded in second pipeline outer end, the left end of second docking tee is connected with backwash inlet electric valve by flange, the right end of second docking tee is connected with water outlet electric valve by flange. The utility model is high in backwash efficiency, backwash is more thorough, reduce operating cost, improve equipment processing capacity.

The application discloses a variable-speed filter device, which comprises a filter tank body, a water distribution plate arranged horizontally in the filter tank body, a water collecting area below the water distribution plate, a water inlet baffle and a backwashing baffle arranged vertically from the upper portion of the water distribution plate to the top of the filter tank body, a double-ring type variable-speed water distributor arranged between the water inlet baffle and the backwashing baffle, a graded pad layer arranged above the water distribution plate between the water inlet baffle and the backwashing baffle, and graded filter material arranged in the graded pad layer; a water inlet is arranged on the upper portion of one side of the filter tank body, a backwashing side flushing port is arranged on the backwashing baffle; a water inlet electric adjusting mechanism is arranged at the water inlet and used for controlling water inlet and reverse side flushing. The variable-speed filter device is more reasonable in design of filter water inlet and backwashing filter speed, more stable in water outlet, and better in cleaning and backwashing effect.
