[0031] As Figure 1 - Figure 7 shown: The drum hydraulic screen for sewage treatment includes a treatment tank 1, and a screening mechanism 2 is arranged inside the treatment tank 1;

[0032] The sieving mechanism 2 includes: a protection box 201, a motor 202, and a collection tank 208. The left side wall of the protection box 201 is fixedly connected to the right side wall of the processing box 1. The motor 202 is fixedly connected inside the protection box 201. The protection box 201 is provided to protect the internal motor 202 and to fix the motor 202 to the right side wall of the processing box 1 to drive the devices inside the processing box 1 to rotate.

The left end of the filter cylinder 205 is fixedly connected to the right end of the support ring 207. The left end of the transfer pipe 206 is connected to external pipes and equipment to transfer sewage through the transfer pipe 206 into the inside of the filter cylinder 205 for treatment. When the filter cylinder 205 rotates, the support ring 207 at the left end of the filter cylinder 205 rotates on the outside of the transfer pipe 206 to support the left end of the filter cylinder 205. The right side wall of the collection tank 208 is arranged on the right inner wall of the support ring 207. The top of the rear side wall of the collection tank 208 is fixedly connected to a support plate 209. A scraper 210 is threadedly connected to the top of the support plate 209. After sewage enters the inside of the filter cylinder 205, the filter cylinder 205 drives the sewage and impurities to rotate, causing the impurities to adhere to the inner wall of the filter cylinder 205. When rotating, the support plate 209 on the collection tank 208 is connected to the scraper 210, and the scraper 210 scrapes the impurities on the inner wall of the filter cylinder 205 and falls into the inside of the collection tank 208 for collection. The top of the scraper 210 is arranged corresponding to the inner wall of the filter cylinder 205. A sewage discharge pipe 211 penetrates through the left side of the collection tank 208. The bottom end of the sewage discharge pipe 211 penetrates through the bottom wall of the transfer pipe 206 and is fixedly connected to the rear side wall of the processing box 1. When the impurities fall into the inside of the collection tank 208, a small amount of sewage will enter the inside of the collection tank 208 to drive the impurities to be discharged from the inside of the processing box 1 through the sewage discharge pipe 211.

[0033] Such as Figure 1 - Figure 9As shown in the figure, a control panel 3 is fixedly connected to the right side wall of the processing tank 1. The entire device is controlled through the set control panel 3. A guide plate 4 is fixedly connected to the inner bottom wall of the processing tank 1. A drain port 5 penetrates through the front side wall of the processing tank 1. The sewage flowing out from the holes of the filter cylinder 205 is guided through the set guide plate 4 and discharged from the processing tank 1 through the drain port 5. A first fixing plate 6 is fixedly connected to the rear side wall of the processing tank 1. A pumping pump 7 is arranged on the upper side wall of the first fixing plate 6. The first fixing plate 6 is used to support and fix the pumping pump 7 at the top. A connecting pipe 8 is fixedly connected to the input end of the pumping pump 7, and a delivery pipe 9 is fixedly connected to the output end of the pumping pump 7. The connecting pipe 8 at the input end of the pumping pump 7 is connected to an external water tank, water pipe, etc. to transfer water to the pumping pump 7 and then transfer it to the inside of the spray pipe 10 through the delivery pipe 9 at the output end.

[0034] As Figure 1 - Figure 9 As shown in the figure, the top end of the delivery pipe 9 is connected to the spray pipe 10 in a communicating manner. A spray head 11 is connected to the front side wall of the spray pipe 10 in a communicating manner. After the water is transferred to the spray pipe 10 through the delivery pipe 9, the water will be sprayed out through the spray head 11 to spray water on the rotating filter cylinder 205. Second fixing plates 12 are fixedly connected to both the left and right ends of the spray pipe 10. The rear side walls of the two second fixing plates 12 are fixedly connected to the inner rear side wall of the processing tank 1. The spray pipe 10 is fixed to the inner rear side wall of the processing tank 1 through the second fixing plates 12 at both the left and right ends of the spray pipe 10.

[0035] As Figure 1 - Figure 11 As shown in the figure, a connecting plate 13 is fixedly connected to the rear side wall of the collection tank 208. A first brush 14 is threadedly connected to the other side of the connecting plate 13. The connecting plate 13 is used to connect with the first brush 14, and the inner wall of the filter cylinder 205 after being scraped by the scraper 210 is cleaned through the first brush 14 to prevent fine impurities, etc. from remaining on the inner wall of the filter cylinder 205, so that the impurities fall off from the holes of the filter cylinder 205 and flow into the inside of the filter cylinder 205 and are cleaned again by the scraper 210. The first brush 14 is arranged corresponding to the inner wall of the filter cylinder 205. An inclined plate 15 is fixedly connected to the inner rear side wall of the processing tank 1. The inclined plate 15 is arranged at the bottom of the spray pipe 10. By arranging the inclined plate 15 at the bottom of the spray pipe 10, the falling water is guided to contact the surface of the filter cylinder 205. A concave plate 16 is threadedly connected to the outer side of the front side wall of the inclined plate 15. A second brush 17 is fixedly connected to the other side of the concave plate 16. The second brush 17 is arranged on the outer surface of the rear part of the filter cylinder 205. The concave plate 16 on the inclined plate 15 is used to connect with the second brush 17 to clean the outer surface of the filter cylinder 205.

[0036] It should be noted that the present utility model is a drum hydraulic screen for sewage treatment. First, the motor 202, the pumping pump 7, and the control panel 3 are connected to an external power source to supply power to the device.

[0037] When the sewage treatment work starts, the sewage is first connected to external equipment pipelines through the adapter pipe 206, and the sewage is introduced into the treatment tank 1. Then, the sewage flows into the interior of the filter cylinder 205 through the adapter pipe 206. The motor 202 is started, and the output end of the motor 202 drives the rotating shaft 203 to rotate. The rotating shaft 203 rotates stably within the fixed column 204, and the filter cylinder 205 connected to its left end also rotates accordingly, thereby driving the sewage and impurities inside to rotate through the filter cylinder 205.

[0038] As the filter cylinder 205 continues to rotate, impurities will gradually accumulate on the inner wall of the filter cylinder 205. When the filter cylinder 205 rotates to the position where it contacts the scraper 210, the scraper 210 will scrape the impurities accumulated and adhered to the inner wall of the filter cylinder 205. The impurities scraped off by the scraper 210 will fall into the collection tank 208. When the impurities in the collection tank 208 accumulate to a certain extent, the impurities are discharged from the interior of the treatment tank 1 through the sewage discharge pipe 211. At the same time, the filtered sewage will flow into the interior of the treatment tank 1 through the holes of the filter cylinder 205, be collected, and be guided by the flow guide plate 4 inside the treatment tank 1, and the sewage is discharged through the drain port 5 on the front side wall of the treatment tank 1.

[0039] During the sewage treatment process, after preliminary treatment by the sieving mechanism 2, the pumping pump 7 is connected to external water pipes and water tanks through the connecting pipe 8 to pump water, and then the water is transported to the spray pipe 10 through the delivery pipe 9 at the output end. The spray pipe 10 is stably fixed on the rear inner wall of the treatment tank 1 under the support of two second fixing plates 12. Water sprays out from the nozzles 11 on the front side wall of the spray pipe 10 to form a certain spraying effect to spray and wash the outside and inside of the filter cylinder 205.

[0040] When the filter cylinder 205 rotates, the first brush 14 can clean the inner wall of the filter cylinder 205 to prevent impurities from accumulating excessively on the inner wall of the filter cylinder 205 and affecting the filtering effect. At the same time, the water sprayed out from the nozzles 11 can also assist the first brush 14 in the cleaning work, flushing away the impurities cleaned by the brush and the fine particles remaining on the inner wall of the filter cylinder 205.

[0041] Outside the filter cartridge 205, the inclined plate 15 fixedly connected to the rear inner wall of the processing box 1 functions as a diversion and support. The concave plate 16 threadedly connected to the outer side of the front side wall of the inclined plate 15 is fixedly connected with a second brush 17, and the second brush 17 is arranged on the outer surface of the rear part of the filter cartridge 205. When the filter cartridge 205 rotates, the second brush 17 cleans the outer surface of the filter cartridge 205 and scrapes off the impurities attached to the outside. The water sprayed by the nozzle 11 also flows onto the inclined plate 15, and part of the water flows along the inclined plate 15 to the contact position between the filter cartridge 205 and the second brush 17, further enhancing the cleaning effect and washing away the scraped impurities.
