[0034] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0035] As Figures 1-4 shown, a filtering component for a waste water purifier proposed in this implementation manner includes a bottom plate 1, and further includes,

[0036] An installation base 2, which is installed at the top end of the bottom plate 1, and a second connecting seat 14 is arranged inside the installation base 2;

[0037] A sewage discharge structure 9, which is arranged at the bottom end of the second connecting seat 14 and is used for discharging foreign matters inside the second connecting seat 14;

[0038] A precision ceramic layer 3, which is installed at the top end of the sealing ring 13, an activated carbon layer 10 is arranged inside the sealing ring 13, a stainless steel filter screen 11 is arranged inside the activated carbon layer 10, and a first connecting seat 12 is fixed at the top end of the precision ceramic layer 3;

[0039] A top plate 4, which is arranged at the top end of the first connecting seat 12. A sealing ring 13 is installed at the connection position between the top plate 4 and the first connecting seat 12. A connecting column 5 connected to the bottom plate 1 is inserted inside the top plate 4, and a locking bolt 6 is threadedly connected to the outside of the connecting column 5. Lifting handles 7 are installed on both sides of the top end of the top plate 4;

[0040] A cleaning structure 8, which is arranged inside the stainless steel filter screen 11. Among them, the cleaning structure 8 includes a transmission component installed inside the stainless steel filter screen 11, a rotating shaft 802 inserted inside the transmission component, a connecting plate 805 fixed to the outside of the rotating shaft 802, and a first scraping strip 803 fixed to one side of the connecting plate 805.

[0041] As Figure 1 , Figure 2 and Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the transmission assembly includes a top support base 806 installed at the top end inside the stainless steel filter screen 11, a bottom support base 804 installed at the bottom end inside the stainless steel filter screen 11, and a water wheel 801 fixed to the top end of the rotating shaft 802. The rotating shaft 802 passes through the top support base 806 and is connected to the water wheel 801. A rotating structure is formed between the rotating shaft 802 and the top support base 806. A plurality of groups of connecting plates 805 are arranged on the outer side of the rotating shaft 802, and the plurality of groups of connecting plates 805 are spirally distributed on the outer side of the rotating shaft 802. Waste water rushes into the inside of the stainless steel filter screen 11 through the first connecting seat 12. At the same time, the waste water flow drives the water wheel 801 to rotate, so that the water wheel 801 drives the first scraping strip 803 and the connecting plate 805 to rotate through the rotating shaft 802. Then, the rotating connecting plate 805 scrapes the foreign objects attached inside the stainless steel filter screen 11, keeping the holes on the surface of the stainless steel filter screen 11 unobstructed. At the same time, the scraped foreign objects precipitate to the bottom of the second connecting seat 14 along the inclined surface of the first scraping strip 803. The positions of the rotating shaft 802 are restricted by the bottom support base 804 and the top support base 806.

[0042] As Figure 2 , Figure 3 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the sewage discharge structure 9 includes a sewage discharge port 902 fixed to the bottom end of the second connecting seat 14, a sewage discharge cover 901 installed at the bottom end of the sewage discharge port 902, a brush rod 905 fixed to the top end of the sewage discharge cover 901, brush filaments 906 fixed to the outer side of the brush rod 905, a plastic strip 903 fixed to the outer side of the top end of the sewage discharge cover 901, a second scraping strip 904 installed on one side of the plastic strip 903, and an auxiliary ring 907 sleeved on the outer side of the plastic strip 903. External threads are provided on the outer side wall of the sewage discharge cover 901, and internal threads matching the external threads are provided inside the sewage discharge port 902. When too many foreign objects accumulate inside the device, rotate the sewage discharge cover 901 to open the sewage discharge port 902, so that the sludge flushes out along with the water flow. At the same time, during the rotation of the sewage discharge cover 901, the plastic strip 903 and the brush filaments 906 disperse the accumulated sludge, making it difficult for the sludge to agglomerate and block. At the same time, the foreign objects on the inner wall of the second scraping strip 904 can be scraped off. Pull the auxiliary ring 907 upward to make the auxiliary ring 907 squeeze the plastic strip 903 to bend and deform, so as to facilitate putting the plastic strip 903 into the inside of the sewage discharge port 902.

[0043] Specifically, when the filter component of this wastewater purifier is in use: the device is installed inside the purifier by holding and lifting the handle 7, so that the sewage enters the inside of the filter cylinder through the holes at the top of the top plate 4. The large particulate suspended solids in the wastewater are initially removed by the stainless steel filter screen 11. Immediately afterwards, the activated carbon layer 10 removes harmful substances such as organic matter and heavy metal ions in the wastewater through physical adsorption. Most of the dissolved ions, organic matter and microorganisms are intercepted by the precision ceramic layer 3, thereby filtering the sewage. The sewage discharge structure 9 discharges the foreign matters accumulated inside the device, and at the same time, the cleaning structure 8 cleans the foreign matters on the inner wall of the stainless steel filter screen 11.

[0044] The wastewater surges into the inside of the stainless steel filter screen 11 through the first connecting seat 12. At the same time, the wastewater flow drives the water wheel 801 to rotate, so that the water wheel 801 drives the first scraping strip 803 and the connecting plate 805 to rotate through the rotating shaft 802. Immediately afterwards, the connecting plate 805 is rotated to scrape the foreign matters attached inside the stainless steel filter screen 11, so that the holes on the surface of the stainless steel filter screen 11 remain unblocked. At the same time, the scraped foreign matters settle to the bottom of the second connecting seat 14 along the inclined surface of the first scraping strip 803. The position of the rotating shaft 802 is restricted by the bottom support seat 804 and the top support seat 806;

[0045] When too many foreign matters accumulate inside the device, the sewage discharge cover 901 is rotated to open the sewage discharge port 902, so that the sludge is washed out along with the water flow. At the same time, during the rotation of the sewage discharge cover 901, the plastic strip 903 and the brush filaments 906 disperse the accumulated sludge, so that the sludge is not easy to agglomerate and block. At the same time, the foreign matters on the inner wall of the second scraping strip 904 can be scraped off. The auxiliary ring 907 is pulled upwards, so that the auxiliary ring 907 can squeeze the plastic strip 903 to bend and deform, so as to facilitate putting the plastic strip 903 into the inside of the sewage discharge port 902.

[0046] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
