Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage treatment, in particular to a rainwater and sewage treatment device. Background Art

[0002] The current drainage system is to separate rainwater from sewage, which means to separate rainwater from the dirt in it. Rainwater is discharged into the river through the rainwater pipe network, and sewage is sent to the sewage treatment plant through the sewage pipe network for treatment. In the early stage of rainwater discharge into the pipe network, it is necessary to filter the rainwater. At present, centrifugal rainwater filters are widely used, and their structure can be referred to CN210934009U. The shell of the existing centrifugal rainwater filter is generally formed in one piece by PE material. The position of the rainwater inlet and the filtered water outlet cannot be adjusted. Usually, the two face the same side, but the rainwater pipe network is complicated, which makes the installation and piping of the filter more troublesome and needs to be improved.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0016] like Figure 1-Figure 2 As shown, a rainwater and sewage treatment device includes an upper cylinder 1, a lower cylinder 2, a cylindrical filter 3 and an arc-shaped rainwater gutter 4. The upper cylinder 1 and the lower cylinder 2 are arranged up and down, and the top opening of the lower cylinder 2 is rotatably connected to the bottom opening of the upper cylinder 1. The cylindrical filter 3 and the arc-shaped rainwater gutter 4 are fixed inside the lower cylinder 2 from top to bottom. The side of the upper cylinder 1 is provided with a rainwater inlet 11 along its own tangential direction, and the side of the lower cylinder 2 is provided with a filtered water outlet 21 along its own tangential direction. The filtered water outlet 21 corresponds to the cylindrical filter 3, and the bottom of the lower cylinder 2 is provided with a waste outlet 22 corresponding to the arc-shaped rainwater gutter 4.

[0017] The working principle of this device is as follows: rainwater is guided to enter the upper cylinder 1 along the tangent direction of the inner wall of the upper cylinder 1. Under the action of hydraulic force, gravity, etc., the rainwater swirls downward close to the inner wall of the upper cylinder 1, and the rainwater generates centrifugal force to pass through the cylindrical filter 3, filter out clean rainwater, and then discharge from the filtered water outlet 21; solid impurities, leaves, mud and sand in the rainwater settle downward under the action of gravity, and when they are deposited on the conical surface of the rainwater arc-shaped rainwater gutter 4, the swirl is accelerated downward, and then discharged from the dirt outlet 22.

[0018] In actual installation, since the upper cylinder 1 and the lower cylinder 2 can rotate relative to each other, the angles of the rainwater inlet 11 and the filtered water outlet 21 can be changed. While reducing various pipe joints, it can also cope with complex pipe networks, thereby improving the convenience of piping work.

[0019] In this embodiment, a cylinder cover 5 is detachably connected to the top of the upper cylinder body 1 to prevent rainwater from overflowing.

[0020] In this embodiment, the bottom opening of the upper cylinder 1 and the top opening of the lower cylinder 2 are fixed by a clamp 6. Specifically, the bottom opening of the upper cylinder 1 and the top opening of the lower cylinder 2 are respectively protruding outward and provided with an upper flange 12 and a lower flange 23. The top of the cylindrical filter 3 is formed with a flange 31, and the flange of the cylindrical filter 3 is clamped between the upper flange 12 and the lower flange 23. The inner wall of the hoop of the clamp 6 is formed with an annular groove 61. The upper flange 12, the flange of the cylindrical filter 3 and the lower flange 23 are clamped together in the groove 61 on the inner wall of the hoop. The design is reasonable. While ensuring the stability of the structure, the upper cylinder 1 and the lower cylinder 2 can be flexibly rotated.

[0021] In this embodiment, a second flange 41 is formed on the top of the arc-shaped rain gutter 4 , and the outer diameter of the second flange 41 corresponds to the inner diameter of the lower cylinder 2 , thereby limiting the radial direction of the arc-shaped rain gutter 4 .

[0022] In this embodiment, an inner flange 24 is formed below the inner wall of the lower cylinder 2, and the second flange 41 is placed on the inner flange 24 to improve the stability of the installation of the arc-shaped rain gutter 4.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the protection scope of the present invention.
