[0022] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the following will further describe the present application in combination with specific drawings.
[0023] Referring to Figures 1 to 3 A Y-shaped drainage vertical pipe filter shown in the drawing, comprising a drainage vertical pipe body 10 detachably connected at the intersection of the vertical pipe main pipe and the horizontal pipe main pipe, the pipe thickness of the drainage vertical pipe body 10 in the embodiment is 4.0-4.5mm. The inside of the drainage vertical pipe body 10 is respectively provided with a first spiral single blade 20 and a second spiral single blade 30, the first spiral single blade 20 and the second spiral single blade 30 are integrally connected with the inner wall of the drainage vertical pipe body 10, the first spiral single blade 20 and the second spiral single blade 30 are spirally distributed at the top and bottom of the inner wall of the drainage vertical pipe body 10, the cross section of the first spiral single blade 20 and the second spiral single blade 30 in the embodiment is an isosceles triangle.
[0024] The side of the drainage vertical pipe body 10 is communicated with a collecting pipe 11, the drainage vertical pipe body 10 and the collecting pipe 11 in the embodiment are integrally provided and have a "Y" shape structure. And the drainage vertical pipe body 10 and the collecting pipe 11 are both made of HDPE material. Specifically, the drainage vertical pipe body 10 and the collecting pipe 11 made of high-density polyethylene material have good wear resistance, electrical insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvent under room temperature conditions, resistant to acid, alkali and corrosion of various salts.
[0025] A filter structure 40 is arranged inside the collecting pipe 11 to filter large impurities and dirt, and is arranged between the first spiral single blade 20 and the second spiral single blade 30. The filter structure 40 in the embodiment includes a first filter screen plate 41 arranged inside the collecting pipe 11 to filter large impurities, and a second filter screen 42 arranged inside the drain vertical pipe body 10 to filter fine dirt.
[0026] The first filter screen plate 41 is arranged obliquely inside the collecting pipe 11. In order to prevent the first filter screen plate 41 from being washed away by strong water flow, a clamping block 11a is arranged inside the collecting pipe 11 to fix the first filter screen plate 41, and a protrusion 41a is arranged on the first filter screen plate 41 to cooperate with the clamping block 11a. When water flow flows from the top to the bottom of the drain vertical pipe body 10, large impurities in the water flow are intercepted by the first filter screen plate 41, preventing pipe blockage.
[0027] The second filter screen 42 is arranged transversely inside the drain vertical pipe body 10 and close to one side of the second spiral single blade 30, and an annular edge 10a is arranged inside the drain vertical pipe body 10 and close to one side of the second spiral single blade 30 to fix the second filter screen 42. During installation, the second filter screen 42 is clamped into the annular edge 10a, and then when water flow with fine particle-shaped dirt passes through the second filter screen 42, the fine particle-shaped dirt is filtered by the second filter screen to prevent the fine particle-shaped dirt from accumulating in the pipe and causing pipe blockage.
[0028] In order to facilitate the observation of impurities on the first filter screen plate, a through hole 12 is formed in the side wall of the collecting pipe 11, and a transparent observation plate 12a is fixedly arranged in the through hole 12.
[0029] A plurality of reinforcing ribs 20a are arranged inside the first spiral single blade 20 and the second spiral single blade 30. The mechanical strength of the first spiral single blade 20 and the second spiral single blade 30 is greatly improved by arranging the plurality of reinforcing ribs 20a. In the embodiment, a gap is also left between the first spiral single blade 20 and the second spiral single blade 30 and the drain vertical pipe body 10, and the gap is filled with soundproof cotton 50. The soundproof cotton 50 improves the quietness of the drain vertical pipe body 10 by its sound insulation effect. It is detected that when cooperating with a special pipe fitting, the drain capacity of the drain vertical pipe body is increased to more than 12.0 L / s, and the noise is less than 37 dB.
[0030] The top and bottom of the drain vertical pipe body 10 are respectively provided with an upper inspection cover 1 and a lower inspection cover 2, which are connected with the vertical pipe main and the horizontal pipe main through threads.
[0031] The first spiral single blade 20 and the second spiral single blade 30 can dredge the airflow in the pipe, and the filter structure 40 can filter the large impurities and dirty things in the drain vertical pipe body 10, so that the intersection of the vertical pipe main and the horizontal pipe main is prevented from being blocked.

The skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
