Problems solved by technology

[0003] 1. The sewage treated by the equipment is high turbidity sewage, and its filter element needs to be replaced frequently;
[0004] 2. When the equipment is processing high-turbidity sewage, a large amount of suspended matter will directly cover the surface of the filter element to prevent the sewage from passing through the filter element, reducing the efficiency of sewage treatment

Embodiment 1

[0027] like figure 1 As shown, a sewage filtering device includes a cylinder body 1 and a filter cover 9 . A support plate 2 is provided at the lower end of the cylinder body 1 . A water production chamber 4 is formed between the cylinder base 3 and the support plate 2 , and the water production chamber 4 is provided with a water outlet 5 . A water inlet 6 is arranged on the cylinder body 1 , and an annular support 10 is provided on the inner wall of the cylinder body 1 below the water inlet 6 , and the filter cover 9 is placed on the annular support 10 . The support plate 2 is provided with a plurality of hollow filter elements 7 , and the support plate 2 is provided with a drain hole 8 connecting the hollow of the filter elements 7 with the water production chamber 4 .

[0028] The filter cover 9 includes a cylindrical support and a filter membrane, and the filter membrane is fixed on the inner wall of the cylindrical support. The filter membrane is made of polypropylene ...

Embodiment 2

[0031] like figure 2 , image 3 As shown, the filter element 7 is provided with a hollow filter element support tube 12 , and a plurality of filter element water permeable holes 13 are provided on the side wall of the filter element support tube 12 . A filter element cap 14 is fixedly arranged on the filter element 7 . The filter element 7 includes a skeleton 18 and a polypropylene layer 19 , and the polypropylene layer 19 is located outside the skeleton 18 . A plurality of water filtering holes 20 are distributed on the skeleton 18 , and the outer surface of the filter element support tube 12 is closely connected to the inner surface of the skeleton 18 . A cap (not shown) is fixed on the filter support tube 12, a screw 15 is fixed on the cap, the filter cap 14 is set on the screw 15, and the filter cap 14 is fixed on the filter element 7 with a nut 16. The setting of the tube cover can prevent untreated water from entering from the upper end of the filter element support ...

Embodiment 3

[0036] see figure 2 and image 3 , This embodiment is the same as Embodiment 2 except for the structure of the filter core. The outer surface of the filter element in this embodiment is wrapped with a hollow filter element support tube, and a plurality of filter element water permeable holes are arranged on the side wall of the filter element support tube. A filter element cap is fixedly arranged on the filter element, and the filter element cap is movably connected with the filter element support pipe. The filter element includes a skeleton and a polypropylene layer, the polypropylene layer is located outside the skeleton, and a plurality of water filtering holes are distributed on the skeleton, and the outer surface of the polypropylene layer is close to the inner surface of the filter element support tube.

Abstract

The invention provides a sewage filtering device which comprises a barrel body, wherein a support plate is arranged on the lower end of the barrel body, a water generating chamber is formed between a base of the barrel body and the support plate, a water outlet is formed in the water producing chamber, a water inlet is formed in the barrel body, a plurality of hollow filtering elements are arranged on the support plate, and drain holes for communicating the hollow filtering elements with the water generating chamber are formed in the support plate. The filtering device also comprises a filtering cover, an annular support member is arranged on the inner wall of the barrel body below the water inlet, and the filtering cover is arranged on the annular support member. The sewage filtering device is also capable of carrying out secondary filtering, and has a relatively good effect for sewage treatment; and meanwhile, the filtering cover is movably connected with the barrel body, so that the filtering cover can be lifted for being cleaned at any time thus being simple and convenient.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage filtering device. Background technique [0002] In sewage treatment, we often encounter devices that need to filter high-turbidity sewage.
