Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figure 1-6 , an embodiment provided by the present utility model: a solid-liquid separation device for domestic sewage, comprising a separation cylinder 1, a top end of the separation cylinder 1 is detachably connected with an end cover 2, a middle part of a top end of the end cover 2 is fixedly connected with a water injection port 3, both left and right sides of the inner wall top end of the end cover 2 close to the water injection port 3 are fixedly connected with connecting rods 11, a bottom end of the connecting rod 11 is fixedly connected with a flow dividing table 12, both front and rear sides of the inner wall top end of the end cover 2 are fixedly connected with fixing rods 15, an upper side of an outer wall of the fixing rod 15 is fixedly connected with a filter screen plate 16. Insert the water inlet pipe into the top of the water injection port 3, and then discharge sewage into the separation cylinder 1. When the sewage passes through the flow dividing table 12, it will flow into the four sides of the filter screen plate 16 in the inclined direction of the flow dividing table 12. A plurality of mounting rings 17 are fixedly connected to a lower side of the outer wall of the fixing rod 15. A top end of an upper mounting ring 17 is detachably connected with a quartz sand filter plate 19, and a top end of a lower mounting ring 17 is detachably connected with an activated carbon plate 18. When the sewage passes through the filter screen plate 16, solid stains will stay on the top of the filter screen plate 16, and the sewage will flow downward and pass through the quartz sand filter plate 19 and the mounting ring 17 to achieve a primary filtering effect on the sewage. Then the sewage will gather in the inner cavity at the bottom of the separation cylinder 1. Both left and right sides of the top end of the mounting ring 17 are fixedly connected with clamping plates 22, and the inner end radius sizes of the clamping plates 22 are the same as the outer wall radius sizes of the activated carbon plate 18 and the quartz sand filter plate 19.

[0027] Specifically, a transfer rod 20 is rotatably connected to the middle of the inner wall of the filter screen plate 16 and penetrates through the upper and lower sides. Brush plates 21 are installed at both the left and right ends of the transfer rod 20. Slots 24 are formed in the inner walls at both the left and right ends of the transfer rod 20. Plug bolts 25 are fixedly connected to the opposite ends of the brush plates 21. The shapes of the outer walls of the plug bolts 25 are all fitted with the shapes of the inner walls of the slots 24. A motor 7 is fixedly connected to the middle of the bottom end of the separation cylinder 1. The driving end of the motor 7 penetrates through the inner wall of the separation cylinder 1 and is fixedly connected to a transmission rod 13. A number of stirring rods 14 are fixedly connected to the lower sides at both the left and right ends of the transmission rod 13. A square rod 23 is fixedly connected to the top end of the transmission rod 13. The shape of the outer wall of the square rod 23 is fitted with the shape of the inner wall of the bottom end of the transfer rod 20. A discharge pipe 8 is fixedly connected to the right side of the bottom end of the separation cylinder 1. The deodorant and disinfectant are put in through the feeding hole on the front side of the separation cylinder 1. Then the motor 7 is started, so that the transmission rod 13 drives the stirring rods 14 on both sides to rotate, thereby mixing and stirring the sewage, deodorant and disinfectant. For the fully mixed and treated sewage, the valve on one side of the discharge pipe 8 is directly opened to discharge the sewage. Arc-shaped plates 9 are fixedly connected to the lower parts of the through grooves on the outer sides of the filter screen plate 16 near the front and rear ends of the separation cylinder 1. Arc-shaped receiving boxes 10 are detachably connected to the top ends of the arc-shaped plates 9. During the stirring process of the sewage, due to the shape of the inner wall of the bottom end of the transfer rod 20 being fitted with the shape of the outer wall of the square rod 23, the transfer rod 20 drives the brush plates 21 on both sides to rotate, thereby scraping the solid stains on the surface of the filter screen plate 16. With the conical shape at the top of the filter screen plate 16, the stains are discharged into the arc-shaped receiving boxes 10 through the through grooves on both sides of the separation cylinder 1.

[0028] Specifically, bottom plates 4 are fixedly connected to both the left and right ends of the separation cylinder 1. Hydraulic rods 5 are fixedly connected to the top ends of the bottom plates 4. The driving ends of the hydraulic rods 5 are fixedly connected with top plates 6. The opposite ends of the top plates 6 are respectively fixedly connected to both the left and right ends of the end cover 2. The shapes of the outer walls of the filter screen plate 16 and the mounting ring 17 are both fitted with the shape of the inner wall of the separation cylinder 1. The shapes of the middle parts of the inner walls of the activated carbon plate 18 and the quartz sand filter plate 19 are both fitted with the shape of the outer wall of the transmission rod 13. The two hydraulic rods 5 are started to push the top plates 6 to drive the end cover 2 to move upward, so that the fixing rods 15 on both sides drive the filter screen plate 16 and the mounting ring 17 to extend towards the top of the separation cylinder 1. At the same time, the bottom end of the transfer rod 20 also disengages from the outer wall of the square rod 23. The plug bolts 25 are directly pulled out of the slots 24 and the brush plates 21 are separated from the top of the filter screen plate 16, so as to clean the brush plates 21, avoid excessive stains on the surface of the brush plates 21 and affect the subsequent cleaning effect of scraping the stains. When the quartz sand filter plate 19 and the activated carbon plate 18 are used multiple times, they can be respectively lifted out from the top of the mounting ring 17 for flushing or replacement, so as to avoid excessive accumulation of stains in the quartz sand and activated carbon, which affects the sewage filtration and flow effect.

[0029] Working principle: First, insert the water inlet pipe into the top of the injection port 3, and then discharge sewage into the separation cylinder 1. When the sewage passes through the diversion table 12, it will flow into the four sides of the filter screen plate 16 in the inclined direction of the diversion table 12. When the sewage passes through the filter screen plate 16, solid stains will remain on the top of the filter screen plate 16, while the sewage will flow down and pass through the quartz sand filter plate 19 and the mounting ring 17 to achieve the primary filtration effect on the sewage. After that, the sewage will accumulate in the inner cavity at the bottom of the separation cylinder 1, and then deodorant and disinfectant are put in through the feeding holes on the front side of the separation cylinder 1. Then, start the motor 7 to drive the transmission rod 13 to drive the stirring rods 14 on both sides to rotate, so as to mix and stir the sewage, deodorant and disinfectant. After the sewage is fully mixed and treated, directly open the valve on one side of the discharge pipe 8 to discharge the sewage. During the process of stirring the sewage, due to the shape of the inner wall at the bottom of the adapter rod 20 fitting the outer wall shape of the square rod 23, the adapter rod 20 drives the brush plates 21 on both sides to rotate, so as to scrape the solid stains on the surface of the filter screen plate 16. With the conical shape on the top of the filter screen plate 16, the stains are discharged into the arc-shaped material receiving box 10 through the through grooves on both sides of the separation cylinder 1. In addition, the stains on both sides will be scraped to the through grooves on both sides by the brush plates 21. Then, start the hydraulic rods 5 on both sides to push the top plate 6 to drive the end cover 2 to move up, so that the fixed rods 15 on both sides drive the filter screen plate 16 and the mounting ring 17 to extend out of the separation cylinder 1. At the same time, the bottom of the adapter rod 20 also disengages from the outer wall of the square rod 23. Pull out the bolt 25 directly from the slot 24 and separate the brush plate 21 from the top of the filter screen plate 16, so as to clean the brush plate 21 and avoid too much stains on the surface of the brush plate 21, which affects the cleaning effect of scraping stains in the follow-up. When the quartz sand filter plate 19 and the activated carbon plate 18 are used many times, they can be lifted out from the top of the mounting ring 17 respectively for flushing or replacement.
