Description
Technical Field
The invention belongs to the technical field of domestic sewage discharge, and particularly relates to a sewage filter at a sewage discharge outlet, which is particularly suitable for filtering indoor domestic sewage.
Background
The existing sewage filter sieve (usually, a filter screen and a long hole filter sieve) can be blocked after being used for a period of time, the filter sieve needs to be frequently turned over for cleaning, most of the blocking objects are fine flexible dirt such as noodles, Chinese chives and hair, and the fine flexible dirt can not block a sewage discharge pipeline, so that the sewage discharge pipeline can be discharged from the filter sieve, but the flexible dirt can be hung on the filter sieve, so that the flexible dirt cannot be discharged, and the consequence is that the flexible dirt can block the filter sieve after being accumulated much, so that the filter sieve needs to be frequently turned over for cleaning, and the cleaning is very troublesome. In order to solve the problem that the filtering screen is easy to block, CN203080643U discloses a floor drain, which comprises an upper metal plate and a vertical filtering device (vertical filtering net and lower metal plate are collectively called vertical filtering device) arranged below the upper metal plate, and attempts to prolong the time to block by a four-side sewage filtering method (actually, any floor drain or filtering screen, sewage enters from four sides first under the action of gravity), but the filtering net is still required to be taken out and cleaned after being blocked by flexible dirt, and the fine flexible dirt is hung on the filtering net, and the cleaning is still troublesome.
Disclosure of Invention
Aiming at the defect that the sewage filter sieve and the floor drain are difficult to clean after being blocked by flexible dirt, the invention aims to provide a novel sewage filter for a sewage draining outlet, which can easily wash away the flexible dirt hung on the filter and can be cleaned without taking out the filter.
The invention is realized by the following steps: a sewage filter for a sewage draining exit comprises a circular base plate (1) and a vertical filtering device arranged below the circular base plate (1), wherein the vertical filtering device filters sewage from four sides, and is characterized in that the vertical filtering device is a plurality of filtering sheets (2) which are fixedly connected with the bottom surface of the circular base plate (1), are vertical to the base plate and point to the axis of the base plate, the outer end surfaces (3) of the filtering sheets (2) incline inwards and downwards, the filtering sheets (2) are uniformly distributed along the circumference of the circular base plate (1) by taking the axis of the circular base plate (1) as a symmetric center, a cylinder (4) which is coaxial with the circular base plate (1) is fixedly connected with the bottom surface of the circular base plate (1), the height of the cylinder (4) is more than 2 times of the height of the filtering sheets (2), 3 to 4 wing plates (5) which can be inserted into the sewage draining exit are fixedly connected between the cylinder (4) and, the height of pterygoid lamina (5) equals the height of drum (4), and the length of pterygoid lamina (5) + the radius of drum (4) slightly is less than the radius of drain, and under the blowdown state, pterygoid lamina (5) of drain filter insert in the drain, and cassette (2) card is on the peripheral subaerial of drain, and cassette (2) constitute the filtration pore of crossing that can the manual work opened the lower part with the peripheral ground of drain.
For a sewage filter with a smaller sewage discharge outlet, the cylinder (4) can be made into a solid cylinder.
The invention has the positive effects that: as the filter sheet (2) of the sewage filter at the sewage draining outlet and the ground at the periphery of the sewage draining outlet form a filter hole which can be manually opened at the lower part, when the flexible sewage hung on the filter sheet (2) is accumulated to a certain degree and needs to be cleaned, the sewage draining outlet filter can be slightly lifted, so that the filter sheet (2) is away from the ground at the periphery of the sewage draining outlet (equivalent to the lower part of the filter hole is opened), and because the outer end surface (3) of the filter sheet (2) is inclined downwards along the water flow direction, the flexible sewage can be separated from the filter sheet (2) along the inclined direction under the action of gravity and the driving of the water flow and flows into a sewage draining pipe from the lower part of the filter sheet (2), the cleaning is very convenient. The sewage filter of the sewage draining outlet of the invention is generally matched with the trap for use, and can be applied to sewage draining of bathroom ground, toilet ground, kitchen ground, sink and the like.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Figures 1 to 3 show the concrete structure of the sewage filter of the sewage draining exit of the invention, which is formed by plastic injection molding, the main structure of the sewage filter of the sewage draining exit of the invention is that a plurality of filter sheets (2) which are vertical to the base plate and point to the axis of the base plate are fixedly connected with the bottom surface of the circular base plate (1), the outer end surfaces (3) of the filter sheets (2) are inwards and downwards inclined, the filter sheets (2) are uniformly distributed along the circumference of the circular base plate (1) by taking the axis of the circular base plate (1) as the symmetrical center, on the basis, the bottom surface of the circular base plate (1) is fixedly connected with a cylinder (4) which is coaxial with the circular base plate (1), the height of the cylinder (4) is more than 2 times of the height of the filter sheets (2), 3 to 4 wing plates (5) which can be inserted into the sewage draining exit are fixedly connected between the cylinder (4) and the filter sheets (2), the, the length of the wing plate (5) and the radius of the cylinder (4) are slightly smaller than the radius of the sewage draining outlet. Under the state of sewage discharge (see figure 4), a wing plate (5) of a sewage discharge outlet filter is inserted into a sewage discharge pipe (sewage discharge outlet) (7), a filter sheet (2) is clamped on the ground (6) at the periphery of the sewage discharge outlet, the filter sheet (2) and the ground (6) at the periphery of the sewage discharge outlet form a filter hole with the lower part opened manually, when flexible dirt (such as hair, noodles, Chinese chives and the like) hung on the filter sheet (2) is accumulated to a certain degree and needs to be cleaned, the sewage discharge outlet filter can be lifted slightly, the filter sheet (2) is separated from the ground at the periphery of the sewage discharge outlet (equivalent to the lower part of the filter hole), because the outer end surface (3) of the filter sheet (2) inclines downwards along the water flow direction, the flexible dirt can be separated from the outer end surface (3) of the filter sheet (2) along the inclined direction under the action of gravity and the drive of water flow, and flows into the sewage discharge pipe from the lower part of the filter sheet (2) (if larger dirt which possibly blocks the sewage discharge . Secondly, if the overlong slender solid matters such as chopsticks, toothpicks, plant branches and the like enter the filtering holes, the slender solid matters are blocked by the wing plates (5) and the cylinder (4) and are prevented from entering the sewage discharge pipe. The blocked elongated solids are manually cleaned.
The number of the filter sheets (2) is determined by the size of the sewage filter of the sewage draining exit and the requirement on the width of the filter hole, and the larger the size of the sewage filter of the sewage draining exit is, the more the number of the filter sheets (2) is; the smaller the sewage filter at the sewage outlet is, the fewer the number of the filter sheets (2) is; the narrower the width of the filter holes is, the more the number of the filter sheets (2) is; the wider the width of the filter hole, the fewer the number of the filter sheets (2), for example, the width of the filter hole is designed to be about 10 mm in a sewage filter of a sewage discharge outlet matched with a sewage discharge pipe (sewage discharge outlet) with the diameter of 75 mm, so the number of the filter sheets (2) is designed to be about 21.
The height of the cylinder (4) and the wing plate (5) is based on the principle that long and thin solid matters with the length being 0.6 times larger than the diameter of the sewage discharge pipe (sewage discharge outlet) can be prevented from entering the sewage discharge pipe, so that the height of the cylinder (4) and the wing plate (5) is generally more than 2 times of the height of the filter (2).
For a sewage filter with a smaller sewage discharge outlet, the cylinder (4) can be made into a solid cylinder.
The thickness of the filter sheet (2) and the wing plate (5) can be between 1.5 and 2.5 millimeters.
The embodiment shown in figures 1 to 3 may also be provided without the cylinder (4) and still not affect the ease of cleaning the waste filter but reduce the effectiveness of filtering elongated solids.
