Description

Hydraulic drive cleaning runner type screen filtering device

Technical Field

The utility model relates to the field of surface water treatment filtering equipment, in particular to a hydraulic drive cleaning runner type screen filtering device.

Background

The conventional equipment for treating and filtering surface water silt and other pollutants mainly comprises a sand filter, a screen filter and a lamination filter.

(1) The sand filter is used for intercepting impurities in water when sewage passes through a quartz sand filter material, mainly has the function of resistance interception and is mainly used for removing suspended matters in water. After water flow enters from the water inlet of the filter and flows through the filter layer, suspended impurities in the water flow are adsorbed and filtered by the filter layer, and then the water flows to the water outlet from the water filtering cap. The cleaning of the filter can be completed by back flushing, the water flow at the moment reversely flows upwards from the water filtering cap to cause turbulent disturbance of the filtering layer, the adsorbed impurities are released and discharged through the discharge valve, and pollutants such as dirt and the like are quickly flushed away. The device has the disadvantages of high requirement on working pressure, high hydraulic loss, more labor consumption for manual cleaning, easy occurrence of water blocking and flow breaking events, and more water resources caused by frequent automatic cleaning;

(2) the screen filter is used for intercepting and retaining impurities with particle sizes larger than the size of a filter mesh in water on the surface of the filter screen when sewage passes through the filter screen, and filtered water flows out through the water outlet. The filter screen of the filter is cleaned by two types, namely manual cleaning and automatic cleaning, wherein firstly, the filter screen is cleaned manually, water is directly cut off, then the filter screen is taken out, and a manager cleans the filter screen by clean water; and secondly, automatic cleaning is carried out, impurities on the surface of the filter screen can be adsorbed by an adsorption device on the cleaning equipment and are discharged by a drain valve to finish cleaning, or the impurities adsorbed by the filter screen are released by the disturbance of the brush and are discharged by a discharge valve. The device has the disadvantages of high requirement on working pressure, high hydraulic loss, more labor consumption for manual cleaning, easy occurrence of water blocking and flow breaking events, and more water resources caused by frequent automatic cleaning;

(3) the lamination filter intercepts and retains impurities with particle sizes larger than the size of the lamination stacking hole opening in water on the surface of the water inlet side when sewage passes through the filter screen, and filtered water flows out through the water outlet. The filter screen of the filter is cleaned by two types, namely manual cleaning and automatic cleaning, wherein firstly, the filter element is directly taken out after water is cut off, and a manager cleans the filter element by clean water; and secondly, automatic cleaning is realized, and impurities on the surface of the filter element can be cleaned through backwashing of purified water and are discharged by a drain valve to finish cleaning. The defects of the method are that the requirement on working pressure is high, hydraulic loss is high, manual cleaning consumes more labor, water blocking and flow breaking are easy to happen, and water resources are wasted due to frequent automatic cleaning.

The existing filtering equipment for sand and other dirt removing devices in a grit chamber, such as a sand filter, a net filter, a laminated filter and the like, is simple in structure, is easy to block water under the condition of not timely cleaning, and can cause water overflow in the grit chamber when the water is blocked seriously, so that the foundation of the grit chamber is eroded, and the grit chamber is damaged.
