[0024] The utility model provides a technical solution: Figure 1-Figure 6As shown, in the present embodiment, a hospital sewage purification treatment device with a multi-stage filtering function comprises a middle-layer filter box 1, the top of the middle-layer filter box 1 is fixedly connected with an upper-layer screening box 2, a screening plate 5 is slidably connected between the inner walls of the upper-layer screening box 2, a lifting component is arranged on the outer side of the upper-layer screening box 2, and the lifting component is used to drive the screening plate 5 to move, an embedding groove 17 is provided on one side of the middle-layer filter box 1, a filter plate 14 is slidably connected between the inner walls of the embedding groove 17, a card slot 16 is provided on one side of the filter plate 14, a cavity 19 is provided inside the middle-layer filter box 1, a card block 18 is slidably connected inside the cavity 19, one end of the card block 18 extends to the inside of the card slot 16, and the inside of the cavity 19 is provided with a card slot 16. A displacement component is provided, and the displacement component is used to drive the block 18 to move. The bottom of the middle filter box 1 is fixedly connected to the lower purification box 4, and the outer side of the lower purification box 4 is fixedly connected to the water outlet 26. A purification component is arranged inside the lower purification box 4, and the output end of the purification component extends to the outer side of the lower purification box 4 and is fixedly connected to the water outlet 26. The purification component includes an ultrafiltration membrane 24 and a reverse osmosis membrane 25, and the ultrafiltration membrane 24 and the reverse osmosis membrane 25 are both fixedly installed inside the lower purification box 4. A water pump 3 is fixedly installed inside the middle filter box 1, and a connecting water pipe 27 is connected in series between the water pump 3, the ultrafiltration membrane 24, the reverse osmosis membrane 25 and the water outlet 26, and an activated carbon filter 15 is arranged inside the filter plate 14.

[0025] When performing sewage treatment operations, the sewage is first introduced into the upper screening box 2, and the large stains in the sewage are screened by the screening plate 5, so that the large stains remain above the screening plate 5, and the screened water flows into the middle filter box 1 through the opening at the bottom of the upper screening box 2. While falling, the sewage will contact the activated carbon filter 15 inside the filter plate 14, and the activated carbon filter 15 will absorb organic matter in the sewage, remove chlorine and odor in the water, so that the filtered water flows into the bottom of the middle filter box 1, and finally the filtered water is pressurized by the water pump 3 so that the water passes through the ultrafiltration. The deep filtration of the membrane 24 and the reverse osmosis membrane 25 removes microorganisms such as bacteria and viruses in the water, so that the purified water flows out from the water outlet 26. During the sewage treatment process, the sieve plate 5 can be lifted by the lifting component, so that the sieve plate 5 can remove the stains remaining on the surface from the water surface, so that the staff can clean it and prevent blockage. After the sewage treatment is completed, the displacement component drives the block 18 to disengage from the inside of the card slot 16, so that the filter plate 14 is unlocked and the filter plate 14 is in an active state, so that the staff can remove it from the inside of the embedded slot 17 and replace it quickly.

[0026] like Figure 1-Figure 6As shown, the lifting assembly includes a first fixed plate 8 and a second fixed plate 9, which are respectively fixedly connected to the two sides of the upper screening box 2, and the top of the first fixed plate 8 is rotatably connected to a threaded rod 10, and the outer side of the threaded rod 10 is threadedly connected to a first L-shaped connecting plate 6, one end of the first L-shaped connecting plate 6 is fixedly connected to the screening plate 5, and a servo motor 11 is fixedly installed at the bottom of the first fixed plate 8, and the output end of the servo motor 11 passes through the first fixed plate 8 and is fixedly connected to the threaded rod 10, and the top of the second fixed plate 9 is fixedly connected to a guide rod 12, and the outer side of the guide rod 12 is slidably connected to a second L-shaped connecting plate 7, one end of the second L-shaped connecting plate 7 is fixedly connected to the screening plate 5, and the guide rod 12 and the top of the threaded rod 10 are both fixedly connected to a limiting plate 13.

[0027] The threaded rod 10 is driven to rotate by the servo motor 11, and the rotation of the threaded rod 10 causes the first fixed plate 8 to drive the screening plate 5 to move up and down under the guidance of the guide rod 12, so that large stains in the upper screening box 2 can be removed from the water surface through the screening plate 5, making it convenient for the staff to quickly clean it.

[0028] like Figure 1-Figure 6 As shown, the displacement assembly includes a slide plate 20, which is slidably connected between the inner walls of the cavity 19, one side of the slide plate 20 is fixedly connected to the block 18, and the other side of the slide plate 20 is fixedly connected to a connecting rod 21, and a spring 22 is fixedly connected to the outside of the connecting rod 21 and located between the slide plate 20 and the inner wall of the cavity 19, and one end of the connecting rod 21 extends to the outside of the middle-layer filter box 1 and is fixedly connected to a pulling block 23.

[0029] By pulling the pulling block 23, the connecting rod 21 is used to drive the slide plate 20 to slide between the inner walls of the cavity 19, so that the block 18 moves accordingly and disengages from the inside of the slot 16, thereby facilitating the release of the lock on the filter plate 14 by driving the block 18 to disengage from the inside of the slot 16, so that the staff can remove the filter plate 14 from the inside of the embedding groove 17 and quickly replace it.

[0030] The utility model provides a hospital sewage purification treatment device with a multi-stage filtering function, and the specific working principle is as follows: when performing sewage treatment operations, the sewage is first introduced into the upper screening box 2, and the screening plate 5 is used to screen the large stains in the sewage, so that the large stains remain above the screening plate 5. At this time, the threaded rod 10 is driven to rotate by the servo motor 11, and the first fixed plate 8 drives the screening plate 5 to be lifted upward under the guidance of the guide rod 12 through the rotation of the threaded rod 10, and the large stains in the sewage are taken away from the water surface, and the staff quickly cleans them, and the screened water flows into the middle filter box 1 through the opening at the bottom of the upper screening box 2. When the sewage falls, it will contact the activated carbon filter 15 inside the filter plate 14, The activated carbon filter 15 absorbs organic matter in the sewage, removes chlorine and odor in the water, and allows the filtered water to flow into the bottom of the middle filter box 1. Finally, the filtered water is pressurized by the water pump 3, so that the water passes through the ultrafiltration membrane 24 and the reverse osmosis membrane 25 for deep filtration to remove microorganisms such as bacteria and viruses in the water, so that the purified water flows out from the water outlet 26. After the sewage treatment is completed, by pulling the pulling block 23, the connecting rod 21 is used to drive the slide plate 20 to slide between the inner walls of the cavity 19, so that the block 18 moves accordingly and disengages from the inside of the card slot 16, so that the filter plate 14 is unlocked, and the filter plate 14 is in an active state, so that the staff can remove it from the inside of the embedded slot 17 and replace it quickly.
