Embodiment 1

[0029] refer to Figure 1-5 , a sewage treatment ultrafiltration device, comprising a box body 1 and an upper cover 2, the upper cover 2 is mounted on the opening at the top of the box body 1 by hinge rotation, the upper cover 2 is fixedly provided with a sewage inlet 3, and the bottom of the box body 1 A purified water outlet 4 is fixedly installed, and the box body 1 is fixedly provided with an annular support plate 5 below the opening at the top thereof. The annular support plate 5 supports a rotating support frame 6, and one side of the rotating support frame 6 passes through the rotating shaft and the box. The inner wall of the top opening of the body 1 is connected by rotation, the ultrafiltration mechanism 7 is detachably installed on the rotation support frame 6, and the cleaning mechanism 8 is installed in the middle of the upper cover 2, and the cleaning mechanism 8 is close to the ultrafiltration mechanism 7 to clean it .

[0030] In the present invention, sealing ...

Embodiment 2

[0038] refer to Figure 6-7 , the present embodiment differs from the first embodiment in that the implementation of the rotating support frame 6, the ultrafiltration mechanism 7 and the cleaning mechanism are different. In this embodiment, the box body 1 and the upper cover 2 are rectangular hollow structures, and the rotating support frame 3 It includes a support frame 61 in a rectangular structure, a support plate 63 of a rectangular frame structure, and a post 64. One side of the support frame 61 is rotationally connected with the inner wall of the top opening of the box body 1 through a rotating shaft. The upper side of the support frame 61 is provided with a rectangular The collection tank 64, the support plate 63 is fixedly arranged on the lower side of the inner wall of the support frame 61, and the support plate 63 is fixedly provided with post posts 64 equidistantly.

[0039] The ultrafiltration mechanism 7 comprises a fixed frame 71 of a rectangular frame structure,...

Embodiment 3

[0043] refer to Figure 1-2 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a backwash pipeline 11 is added in the box body 1. In this embodiment, the backwash pipeline 11 is fixedly installed in the inner cavity of the box body 1 through a bracket. Below the support plate 5 , the backwash pipeline 11 is provided with a plurality of spray holes facing the ultrafiltration mechanism 7 , and the backwash pipeline 11 is connected with a high-pressure water pipe. The backwashing pipeline 11 can reversely flush water toward the ultrafiltration membrane 73 , wash away the impurities on the other side of the ultrafiltration membrane 73 by water pressure, and cooperate with the cleaning mechanism 8 to clean the ultrafiltration membrane 73 .

[0044] The present invention is novel in design, simple in structure, and convenient to use. The ultrafiltration membrane 73 can be replaced and cleaned conveniently through the detachable ultrafiltration mechanism...

Abstract

The invention discloses a sewage treatment ultrafiltration device, and belongs to the field of sewage treatment. The sewage treatment ultrafiltration device comprises a box body and an upper cover, anannular supporting plate is fixedly arranged below an opening in the top of the box body; a rotary supporting frame is supported on the annular supporting plate, one side of the rotary supporting frame is rotatably connected with the inner wall of the opening in the top of the box body through a rotary shaft, an ultrafiltration mechanism is detachably installed on the rotary supporting frame, a cleaning mechanism is installed in the middle of the upper cover, and the cleaning mechanism is close to the ultrafiltration mechanism to clean the ultrafiltration mechanism. The device is novel in design, simple in structure and convenient to use, the ultrafiltration membrane can be conveniently replaced and cleaned through the detachable ultrafiltration mechanism and the rotary supporting frame,the ultrafiltration membrane can be directly cleaned through the cleaning mechanism and the backwashing pipeline in the using process of the device, the working effect of the ultrafiltration membraneis ensured, and the service life of the ultrafiltration membrane is prolonged.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an ultrafiltration device for sewage treatment. Background technique [0002] The ultrafiltration device is an advanced membrane separation technology. The solvent and various small solutes contained in the feed liquid pass through the filter membrane from the high-pressure feed liquid side to the low-pressure side, thereby obtaining the permeate or ultrafiltrate. The micropores of the filter membrane can reach less than 0.01 micron (one hundred thousandth of a millimeter), which can effectively remove particles, colloids, and bacteria in water. [0003] The existing ultrafiltration devices have the following defects: 1. The internal ultrafiltration film is inconvenient to replace. After long-term filtration, particles, colloids and bacteria in the water will block the micropores on the ultrafiltration membrane, thereby affecting the water purification efficiency. ; 2 The ultrafi...
