Abstract
The invention provides a gap-adjustable pollution-discharging backwashing filter. The filter comprises a housing, a water inlet pipe, a water outlet pipe, and two layers of built-in movable filter cylinders, and an inner filter cylinder is connected with a sewage discharging port via a non-return valve. The inner filter cylinder and an outer filter cylinder of the gap-adjustable pollution-discharging backwashing filter are cooperated in a conical-surface cooperation manner, also gaps generated by position cooperation inner annular grooves and outer annular grooves are taken as filter gaps, and the filter precision is adjusted by adjusting the relative positions of the inner filter cylinder and the outer filter cylinder; backwashing is performed when the inner annular grooves and the outer annular grooves are opposite, and an annular shoulder formed by the inner annular grooves and the outer annular grooves helps to remove dirt on a filter surface, so that backwashing is relatively thorough; and the gap-adjustable pollution-discharging backwashing filter has the advantages of being adjustable in filtering precision, free of obstruction, thorough in backwashing and simple in operation, and is beneficial for popularization and usage. The gap-adjustable pollution-discharging backwashing filter solves the problems that a well-mouth filter is constant in filtering precision and cannot adapt to all stratum gaps, backwashing is not thorough and the workload is heavy.
