Abstract

The invention relates to a pressurization back-washing and recharging fine filter unit, which comprises a primary filter, one-stage filters and second-stage filters, wherein a main water inlet pipe is arranged on the primary filter; the primary filter is respectively communicated with the one-stage filters through water branch pipes; the water outlet branch pipes of the one-stage filters are communicated with the second-stage filters; the water outlet branch pipes of the second-stage filters are communicated with a main water outlet pipe; the first-stage filters and the second-stage filters are respectively provided with waste water pipes; the first-stage filters and the second-stage filters are all horizontally arranged; a back-washing pipe is communicated near the water branch pipe of the primary filter; and a recharging pipe is arranged at the bottom end of a back-washing vertical pipe forward. Filtering, back-washing and recharging are organically combined together in the filter unit, and the filtering, back-washing and recharging of the unit are realized through scientifically arranged pipelines by adopting only one (or one set of) booster pump, so that the unit is compact in the whole unit structure, small in occupied space and low in cost while multiple functions are realized.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a filter, in particular to a pressurized recoil and refill fine-effect filter unit. Background technique [0002] No matter it is surface water, ground water or geothermal water, it needs to be filtered during use to filter out suspended solids and harmful substances in the water. The equipment used for filtering is a filter. Since different filter elements of the filter filter different substances, different filter elements need to be used according to the difference in water quality, so a combination of multiple filters is required to achieve the purpose of filtering. At present, although this type of filter unit has appeared, the structure is relatively complicated, the volume is huge, and the space occupied is large, and even cannot be used in some occasions. [0003] During the use of the filter element, the filter holes will inevitably be blocked by the filtrate, so that the f...
