DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figures 1-5 As shown, a water supply and drainage filtration device includes: an inlet pipe 100 and an outlet pipe 200; a filtration mechanism 300, the filtration mechanism 300 including a fixed box 310, the opposite ends of the inlet pipe 100 and the outlet pipe 200 being installed at the top and bottom ends of the fixed box 310 respectively, a filter cover 320 being fixedly connected to the inner bottom wall of the fixed box 310, a first filter plate 330 being fixedly connected to the surface of the filter cover 320, the first filter plate 330 having an overall shape of a flat-topped conical ring, a ring 340 being fixedly connected to the bottom end of the first filter plate 330, two fixed plates 341 being fixedly connected to the surface of the ring 340, the fixed plates 341 being inclined, and collection boxes 350 being fixedly connected to both sides of the fixed box 310, the lower ends of the two fixed plates 341 penetrating into the corresponding collection boxes 350.

[0025] In this embodiment, the inlet pipe 100 is installed to the top of the fixed box 310 via a flange, and the outlet pipe 200 is installed to the bottom of the fixed box 310 via a flange. After installation, the outlet pipe 200 is connected to the filter cover 320. The centers of the inlet pipe 100, the outlet pipe 200, and the filter cover 320 coincide. A sealing plate is installed on one side of the fixed box 310 via bolts. When it is necessary to clean the inside of the fixed box 310, the sealing plate can be opened.

[0026] Both sides of the two fixing plates 341 are fixedly connected to the inner wall of the fixing box 310, so there is no gap between the fixing plates 341 and the inner wall of the fixing box 310.

[0027] A sealing plate is bolted to the bottom of the collection box 350. When it is necessary to clean the inside of the collection box 350, the sealing plate can be removed to carry out the cleaning operation.

[0028] like Figure 5 As shown, the filtration mechanism 300 also includes a second filter plate 351 fixedly connected to the inner wall of the collection box 350. The second filter plate 351 is inclined. Multiple uniformly distributed collection frames 352 are embedded in the inner wall of the second filter plate 351. A sealing plate 353 is installed at the bottom of the collection frame 352. Multiple through holes 354 distributed in a rectangular array are opened on the surface of the sealing plate 353.

[0029] In this embodiment, the mesh diameter of the first filter plate 330 and the mesh diameter of the second filter plate 351 are smaller than the mesh diameter of the filter cover 320, and the diameter of the through hole 354 is smaller than the mesh diameter of the second filter plate 351. When the fixed plate 341 introduces the filtered impurities into the collection box 350, the impurities will fall above the higher end of the inclined surface of the second filter plate 351.

[0030] like Figure 4 As shown, a guide plate 360 ​​is fixedly connected to the lower end of the surface of the filter cover 320. The overall shape of the guide plate 360 ​​is a flat-topped conical ring, and the top of the guide plate 360 ​​is fixedly connected to the inner surface of the first filter plate 330.

[0031] In this embodiment, the opening of the guide plate 360 ​​gradually decreases from top to bottom, and the connection position between the guide plate 360 ​​and the first filter plate 330 is located at the lower end of the inclined surface of the first filter plate 330. As a result, the aqueous solution filtered by the first filter plate 330 will flow into the guide plate 360, and the guide plate 360 ​​will guide the aqueous solution to pass through the filter cover 320 better.

[0032] like Figure 2 and Figure 5 As shown, a three-way pipe 210 is installed on the surface of the water outlet pipe 200, and a connecting pipe 355 is connected to the bottom end of the collection box 350. The other end of the connecting pipe 355 is installed with the three-way pipe 210.

[0033] In this embodiment, after the outlet pipe 200 is installed with the fixed box 310, the other ends of the two connecting pipes 355 are respectively installed with the other ends of the tee pipe 210 through flanges, so that the connecting pipes 355 are connected to the outlet pipe 200. The bottom of the collection box 350 forms an angle with the horizontal plane. The horizontal height of the end of the connecting pipe 355 inside the collection box 350 is higher than the horizontal height of the lowest point of the bottom wall inside the collection box 350. Therefore, when the horizontal height of the water solution retained on the bottom wall inside the collection box 350 is the same as the horizontal height of the end of the connecting pipe 355, the connecting pipe 355 will discharge part of the water solution, and smaller impurities will precipitate on the bottom wall inside the collection box 350.

[0034] like Figure 5 As shown, a filter screen is fixedly connected to one end of the connecting pipe 355, and a one-way valve is installed on the surface of the connecting pipe 355.

[0035] In this embodiment, the connecting pipe 355 can only drain water in one direction under the action of the check valve. It should be noted that the check valve is a relatively mature device in the prior art.

[0036] like Figure 3 As shown, a transparent plate 356 is embedded at one end of the collection box 350. Workers can observe the collection status of impurities inside the collection box 350 through the transparent plate 356.

[0037] like Figure 3 As shown, a fixing ring 331 is fixedly connected to the lower end of the surface of the first filter plate 330, and the surface of the fixing ring 331 is inclined. This facilitates the thorough filtration of the aqueous solution flowing over the surface of the first filter plate 330.

[0038] In use, this invention involves installing the inlet pipe 100 and outlet pipe 200 with the filter mechanism 300. When the aqueous solution enters the fixed box 310 through the inlet pipe 100, the filter cover 320 filters the solution. The filtered solution then passes through the filter cover 320 into the outlet pipe 200 and is discharged. Impurities retained on the filter cover 320 flow to the inclined surface of the first filter plate 330 under the action of the water flow. The first filter plate 330 then separates the aqueous solution from the impurities, and the separated solution flows onto the guide plate 360 ​​and through the filter cover 320 into the outlet pipe 200. Simultaneously, impurities retained on the first filter plate 330 slide down into the corresponding collection box 350 under the action of the inclined surface of the first filter plate 330 and the inclined surface of the fixed plate 341, landing above the higher end of the inclined surface of the second filter plate 351. During this process, the second filter plate 351 filters the falling impurities again, causing the aqueous solution in the impurities to fall into the bottom of the collection box 350. At the same time, the impurities on the second filter plate 351 slide towards the lower part of the inclined surface of the second filter plate 351 under the action of its inclined surface. When the impurities coincide with the first collection frame 352 on the moving path, the impurities will fall into the first collection frame 352 and the aqueous solution entering the collection frame 352 will be discharged through the through hole 354. When the aqueous solution at the bottom of the collection box 350 reaches a certain level, the connecting pipe 355 will guide the aqueous solution into the outlet pipe 200. When the impurities in the first collection frame 352 reach a certain amount and the impurities can no longer enter, the impurities will continue to slide down and enter the second collection frame 352 on the path, and so on. When the impurities in multiple collection frames 352 all reach a certain amount, the device is cleaned.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
