Abstract

The utility model relates to a sparge water filter field especially relates to a filter equipment that can carry out back flush on line, including filter screen, casing, inlet tube and drain pipe, its characterized in that, 45 ~ 55 slopes settings are become to the relative casing bottom of filter screen, and the inlet tube is established at the top of casing, the perpendicular filter screen of inlet tube outlet direction, and the drain pipe is established in the bottom of casing. The water inlet pipe is connected with a water outlet pipe of the flushing water pump through a water inlet valve, and a drain valve is arranged on the drain pipe. Compared with the prior art, the beneficial effects of the utility model are that: the washing of the filter screen can be realized on line, the shutdown and water drainage are not needed, the shutdown times and the shutdown time of the unit are reduced, the unit operation rate is improved, and the time and the labor are saved.

Description

A kind of can the online filter that carries out backwash

Technical field

The utility model relates to the flushing water art of filters, relate in particular to a kind of can the online filter that carries out backwash.

Background technology

The frequent blockage phenomenon of flushing water section filter of pickling associating unit needs after the obstruction to shut down and discharges water, and screen pack is taken out carry out thoroughly clearly, influences the operating rate of unit, and labour intensity is bigger.

Summary of the invention

The purpose of this utility model be to provide a kind of can the online filter that carries out backwash, can on-line cleaning, reduce shutdown number of times and the downtime of unit, improve the unit operation rate.

For achieving the above object, the technical solution of the utility model is:

A kind of can the online filter that carries out backwash, comprise screen pack, housing, water inlet pipe and drainpipe, screen pack becomes 45～55 ° to be obliquely installed with respect to housing bottom, and water inlet pipe is located at the top of housing, water inlet pipe Way out vertically passing filter screen, drainpipe is located at the bottom of housing.

Described water inlet pipe links to each other with the outlet pipe of flush water pump by water intaking valve, and drainpipe is provided with draining valve.

Compared with prior art, the beneficial effects of the utility model are: but the flushing of canbe used on line screen pack need not to shut down and discharge water, reduced shutdown number of times and the downtime of unit, improved the unit operation rate, more time saving and energy saving.
