The utility model discloses a pipeline filter, which comprises a shell, wherein one side of the shell is provided with a water inlet, and the other side of the shell is provided with a water outlet; a backflushing opening is formed above the shell and is positioned on one side close to the water outlet; the middle position in the shell is provided with a filtering device which comprises a bracket and a filter screen arranged in the bracket, the bracket is obliquely arranged, and the upper end and the lower end of the bracket are welded with the inner surface of the shell; an upper cover is arranged at the joint of the upper end of the bracket and the shell, the upper cover is connected with the shell through a screw, and a sealing gasket is arranged between the upper cover and the shell; the casing below is provided with support frame, first drain and second drain are located filter equipment's both sides respectively.

Preferably, the included angle formed between the support and the horizontal ground is 80 degrees.

Preferably, the bottom surface of the housing is a conical surface.

Preferably, the connecting pipelines of the water inlet, the water outlet, the backflushing port and the sewage draining port are all provided with valves.

Preferably, the housing is a stainless steel housing.

Preferably, the support frame is an angle steel support frame.

Compared with the prior art, the beneficial effects of the utility model are that:

1. when the filter is normally used, the valves of the water inlet and the water outlet are opened, and the backflushing port and the two sewage outlets are closed; when the filter needs to be cleaned, the water inlet, the water outlet and the second sewage draining port are closed, and the backflushing port and the first sewage draining port are opened, so that the sewage and the slag on the liquid outlet side can be cleaned; the water inlet, the water outlet and the first sewage draining port are closed, the backflushing port and the second sewage draining port are opened, and sewage residues on the filter screen and on the water inlet side can be cleaned.

2. Through the structural design of filter equipment, casing and upper cover, when the filter screen blockked up, removable filter screen cleared up, easy operation just can also satisfy the requirement that the filtration contains different granularity filth sediment media.
