Description

New energy-saving water treatment filter device

technical field

The invention relates to a filter, in particular to a novel energy-saving water treatment filter device.

Background technique

The quartz sand filter uses quartz sand as the filter medium. Under a certain pressure, the water with high turbidity is filtered through a certain thickness of granular or non-granular quartz sand to effectively intercept and remove suspended solids, organic matter, and glue in the water. It is a high-efficiency filtration equipment that can reduce the turbidity of water and purify water quality by removing particulate matter, microorganisms, chlorine, smell and taste, and some heavy metal ions. The existing filter structure has a tank body, a sieve plate is arranged in the tank body, a support layer of pebble material is arranged above the sieve plate, and a quartz sand layer is arranged above the support layer. The filtered water enters the upper part of the tank body through the valve and the water pipe, then goes down and passes through the quartz sand layer and the supporting layer, and then is discharged through the drain pipe under the tank body. During the filtration process, since the pollutants in the water body are not uniform in particle size, it is easy to block the upper quartz sand filter material first, thereby hindering the circulation of filtered water and affecting the water production efficiency. In order to overcome the blockage of the filter material, frequent reactions are required. Flushing the filter to remove the dirt on the upper layer of the filter material will also increase the workload of complex operations. Manually operating multiple valves to control water inlet, outlet, and backwash is very cumbersome and causes a lot of waste of water resources.
