However, the device still has certain defects in actual use. For example, although the device can shake the box, when the impurities on the top of the filter screen are larger than the filter screen aperture, the impurities will still adhere to the top of the filter screen and cannot be cleaned, which will still affect the use effect of the filter screen. In addition, the filter plate of the device is installed inside the box through fixing bolts, and the excessive humidity inside the box will corrode the fixing bolts, thereby affecting the removal of the filter plate.

[0019] Embodiment:

[0020] Please refer to Figures 1-6 In the figure, a sewage filtering device provided in this embodiment includes: a filter box 1. A horizontal plate 101 is arranged inside the filter box 1. Both sides of the top of the horizontal plate 101 are connected with inclined filter plates 102. Collection components are arranged on both sides of the bottom of the horizontal plate 101 for collecting impurities on the top of the filter plates 102. The collection components include: a collection box 2, a filter net 201, and a return port 202. A disassembly and assembly component is arranged between the horizontal plate 101 and the filter box 1 for disassembling and assembling the horizontal plate 101. The disassembly and assembly component includes: a slide groove 5, a support rod 501, and a box door 502.

[0021] Among them, collection boxes 2 are arranged on both sides of the bottom of the horizontal plate 101. A filter net 201 is installed inside the collection box 2. Return ports 202 are opened on the inner sides of the two collection boxes 2. When sewage falls onto the top of the filter plates 102, the sewage can pass through the filter plates 102, and the impurities in the sewage will be filtered on the top of the filter plates 102. Since the two filter plates 102 are inclined towards the two collection boxes 2 respectively, the impurities on the top of the filter plates 102 can fall into the collection boxes 2, thus preventing the impurities from accumulating on the top of the filter plates 102 and affecting the filtering effect of the filter plates 102. After the impurities fall into the collection boxes 2, they will fall on the top of the filter net 201, and the sewage in the impurities can pass through the filter net 201 and be discharged out of the collection box 2 from the return port 202.

[0022] Among them, through openings 3 are provided on both sides of the outer end of the filtration box 1. One side of the outer ends of the two collection boxes 2 respectively protrudes from both sides of the outer end of the filtration box 1 through the two through openings 3. One side of the outer ends of the two filtration boxes 1 is connected with a handle 301. When it is necessary to clean the impurities inside the collection box 2, the insertion rod 404 is slid out from the jack 403 and the through hole, and then the handle 301 is used to slide the collection box 2 out of the filtration box 1 through the through opening 3, so that it is convenient to clean the impurities inside the collection box 2 after the collection box 2 is removed from the filtration box 1.

[0023] Among them, a vertical plate 4 is connected to one side of the top of each of the two collection boxes 2. A transverse base plate 401 is connected to the inner sides of the two vertical plates 4. Side plates 402 are connected to both sides of the outer end of the filtration box 1. A through hole is provided at the top of the side plate 402. A jack 403 is provided at the top of the transverse base plate 401. An insertion rod 404 slidably connected to the jack 403 is arranged inside the through hole. When installing the collection box 2, the collection box 2 is moved from the through opening 3 into the filtration box 1 until one end of the transverse base plate 401 on one side of the top of the collection box 2 abuts against the outside of the filtration box 1, so that the through hole is aligned with the jack 403, and then one end of the insertion rod 404 is inserted into the jack 403 through the through hole, thereby fixing the transverse base plate 401 and the collection box 2.

[0024] Among them, two sliding grooves 5 are provided on one side of the outer end of the cross plate 101. Two support rods 501 are connected to both sides of the inner wall of the filtration box 1. One end of the support rod 501 is located inside the sliding groove 5. A box door 502 is rotatably connected to one side of the outer end of the filtration box 1 through a hinge. When it is necessary to disassemble and clean the filter plate 102, the box door 502 is opened through the hinge, and then the cross plate 101 is slid outwards towards the outside of the filtration box 1 until the four support rods 501 completely slide out of the sliding groove 5, and then the filter plate 102 can be disassembled from the filtration box 1. When installing the filter plate 102, the cross plate 101 is moved into the filtration box 1, and the four support rods 501 are slid into the sliding groove 5, and the cross plate 101 and the filter plate 102 are supported by the support rods 501.

[0025] Among them, a water inlet pipe 6 is connected to the top of the filtration box 1, a drain pipe 601 is connected to the bottom of the filtration box 1, an opening 602 is provided at the top of the cross plate 101, and flow guide plates 603 are connected to both sides of the bottom of the cross plate 101. When using this device, sewage is introduced into the filtration box 1 through the water inlet pipe 6. The sewage will fall onto the top of the filter plate 102 and pass through the filter plate 102 and the opening 602 and be discharged from the drain pipe 601. The flow guide plates 603 are used to guide the sewage falling from the opening 602 to the drain pipe 601.

[0026] Among them, support seats 7 are connected to both sides of the bottom of the filtration box 1. An observation window 701 is inlaid on one side of the outer end of the box door 502. The support seats 7 are used to support the filtration box 1 to ensure the use of the drain pipe 601, and it is convenient for the staff to check the filtration situation of the filter plate 102 for sewage through the observation window 701.

[0027] Specific usage and functions of this embodiment:

[0028] When using this device, sewage is introduced into the filter box 1 through the water inlet pipe 6. The sewage will fall onto the top of the filter plate 102. The sewage can pass through the filter plate 102, while the impurities in the sewage will be filtered on the top of the filter plate 102. And since the two filter plates 102 are respectively inclined towards the two collection boxes 2, the impurities on the top of the filter plate 102 can fall into the collection boxes 2, thus preventing the impurities from accumulating on the top of the filter plate 102 and affecting the filtering effect of the filter plate 102. After the impurities fall into the interior of the collection boxes 2, they will land on the top of the filter net 201, and the sewage in the impurities can pass through the filter net 201 and be discharged out of the collection boxes 2 from the return port 202. The sewage that has passed through the filter plate 102 will then pass through the opening 602 and be discharged through the drain pipe 601. When it is necessary to disassemble the filter plate 102, open the box door 502 through the hinge, and then slide the cross plate 101 out of the filter box 1 until the four support rods 501 completely slide out of the sliding grooves 5, and then the filter plate 102 can be removed from the filter box 1. When installing the filter plate 102, move the cross plate 101 into the filter box 1 and make the four support rods 501 slide into the sliding grooves 5. The cross plate 101 and the filter plate 102 can be supported by the support rods 501.
