Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

With reference to the accompanying drawings 1-3, the utility model provides a technical solution: a backwash type water filter, including a water filter housing 1, a partition 9 is arranged in the water filter housing 1, and the partition 9 filters The water housing 1 is divided into a lower water inlet chamber 7 and an upper filter chamber 3, and the lower part of the water filter housing 1 is provided with a water inlet 8 communicating with the lower water inlet chamber 7, and a water inlet 8 on the same center line as the water inlet 8. The water outlet 5 , the water inlet 8 and the water outlet 5 are symmetrically arranged on both sides of the water filter housing 1 . A water outlet chamber 6 communicating with the water outlet 5 is provided in the lower water inlet chamber 7 , and the water outlet chamber 6 communicates with the upper filter chamber 3 up and down.

A filter assembly 11 is provided in the upper filter chamber 3, and the filter assembly 11 is set in the upper filter chamber 3 on the side of the water inlet 8, and the filter assembly 11 includes a vertically arranged turret that deviates from the central axis of the water filter housing 1 10. The turret 10 deviates from the central axis of the water filter housing 1 by 100 mm. The top of the water filter housing 1 is provided with a motor 2 that drives the rotary frame 10 to rotate. The rotary frame 10 is equipped with a filter screen cylinder with an open lower end and a closed upper end. The filter screen cylinder is divided into 8 filter units 15 by a partition plate. The filter screen cylinder includes an upper cover plate and a cylindrical filter screen, the upper cover plate is connected with the turntable 10, and the filter unit 15 is a fan-shaped structure.

The partition 9 is provided with a water inlet area 16 and a sewage backwashing area 14 , and the surface area of the water inlet 16 accounts for 66% of the total surface area of the partition 9 . On the water inlet area 16, the partition plate 9 inside each filter unit 15 is provided with an upper water port 12 communicating with the lower water inlet chamber 7, and the upper water port 12 is fan-shaped; The partition 9 inside the unit 15 is provided with a sewage outlet 13 .

There are two kinds of sewage discharge schemes, one is: the sewage discharge port 13 is connected with a sewage discharge pipe, and the other end of the sewage discharge pipe protrudes from the water filter housing 1 .

The other is: the lower water inlet chamber 7 is provided with a sewage discharge chamber, the upper end of the sewage discharge chamber communicates with the sewage discharge port 13, and the sewage discharge pipe connected with the sewage discharge chamber is arranged on the water filter housing 1 .

An arc-shaped cover 4 is arranged on the outside of the water filter housing 1, the upper and lower ends of the arc-shaped cover 4 are closed, the lower end of the arc-shaped cover 4 is flush with the bottom of the water outlet chamber 6, and the arc-shaped cover 4 The upper end of the upper end of the filter chamber 3 is connected to the upper part, and the water outlet 5 is arranged on the central axis of the arc surface of the arc cover 4.
