Description

Technical Field

[0001] The utility model relates to a sand filter layer replacement mechanism, in particular to a sand filter layer replacement mechanism with a discharging component. Background Technique

[0002] The shallow sand filter, also known as a side filter, is mainly used for filtering circulating water, feed water, and wastewater in the industrial field. The medium filtration system of HGBMF uses deep media and can effectively remove particulate matter and reduce turbidity. If specific filter media, such as activated carbon, zeolite, etc., are installed, corresponding organic matters, ions, etc. can also be adsorbed and removed. The fluidization device (bottom drainage device) in the system can fluidize the filter media, remove the pollutants intercepted on the media, and discharge them to obtain thorough cleaning.

[0003] Although the existing shallow sand filters have automatic normal washing and backwashing functions, during backwashing, the water flow impact generated by backwashing cannot effectively drive the circulation of impurities inside the filter sand. Under the layer-by-layer accumulation of impurities in the filter sand, they cannot flow out completely with the backwashing water. Moreover, when using the filter sand for filtration work, when the filter sand needs to be replaced, the tank body often needs to be inverted to pour out the filter sand for replacement, resulting in a relatively high labor intensity. Content of the Utility Model
