[0027] A frame 11 is supported on the base 1, and a secondary filter barrel 8 is supported on the frame 11;
[0028] An internal filter assembly 9 is supported inside the secondary filter barrel 8; the internal filter assembly 9 includes a mounting frame 91 disposed inside the secondary filter barrel 8, an optical axis 92 is vertically supported on the mounting frame 91, an internal filter barrel 93 is sleeved outside the optical axis 92, the internal filter barrel 93 is opened at the upper and lower sides and an activated carbon filter plate 94 is disposed at the opening, and the internal filter barrel 93 is filled with a particle filter layer 95.
[0029] In this embodiment, in actual use, the large impurities in the sewage can be filtered and blocked by the metal filter plate 4, and the sand and gravel filter layer 5 can effectively remove pollutants in the hospital sewage and reduce pollution to the surrounding environment. The sewage after preliminary filtration will be pumped into the inner filter component 9 by the pump 81, and filtered for the second time through the activated carbon filter plate 94 and the particle filter layer 95. At this time, the drug residues, chemical substances and organic waste in the hospital sewage can be further strengthened. Filtration; compared with the single use of activated carbon for filtration treatment in the cited document, the disinfection device of the present application is through the primary filtration of the metal filter plate 4 and the sand and gravel filter layer 5, and the secondary filtration treatment of the activated carbon filter plate 94 and the particle filter layer 95, so that the hospital sewage can be thoroughly filtered and disinfected. At the same time, the ultraviolet disinfection lamp 83 is set, so that the ultraviolet disinfection lamp 83 can disinfect and sterilize the hospital sewage, thereby more effectively removing pollutants in the hospital sewage.
[0030] It should be noted that, during use, the mounting frame 91 and the optical axis 92 can be used to support the inner filter barrel 93, the activated carbon filter plate 94 can be installed on the optical axis 92 using a shaft sleeve, and the mounting frame 91 can ensure stable support for the inner filter barrel 93 to prevent tipping over after the particle filter layer 95 is filled in the inner filter barrel 93, thereby ensuring stable filtration of hospital sewage. The particle filter layer 95 can use a variety of different types of particles, and the specific selection depends on the sewage composition to be filtered and the treatment target. Preferably, sand and gravel particles, activated carbon particles, silica gel particles and fiber particles can be selected; among them, sand and gravel particles can effectively filter suspended matter and solid particles in sewage, and activated carbon particles can be used in the filtration process to remove odor and organic matter.
[0031] Specifically, refer to Figure 1-3 The base 1 also supports a collecting pipe 7 , and the bottom of the primary filter barrel 3 is connected to a flow pipe 6 , and the other end of the flow pipe 6 extends into the collecting pipe 7 and is connected to the collecting pipe 7 .
[0032] In this embodiment, in actual use, the provided circulation pipe 6 can be used to connect the primary filter barrel 3 and the collection pipe 7, and the provided collection pipe 7 can be used to store sewage. When the sewage enters the primary filter barrel 3, due to the filtration treatment of the metal filter mesh plate 4 and the sand and gravel filter layer 5, the sewage will stay in the primary filter barrel 3, and the provided collection pipe 7 can collect the sewage after the first filtration is completed, so as to facilitate the extraction into the secondary filter barrel 8 through the pump 81 for secondary filtration.
[0033] Specifically, refer to Figure 1-3 A pump 81 is mounted on the secondary filter barrel 8 , an input end of the pump 81 is connected to a hose and extends to the collecting pipe 7 , and an output end of the pump 81 penetrates the secondary filter barrel 8 and extends into the secondary filter barrel 8 .
[0034] In this embodiment, the pump 81 is used to extract the sewage in the collection pipe 7, so that the sewage can enter the secondary filter barrel 8 from the collection pipe 7 for secondary filtering treatment.
[0035] Specifically, refer to Figure 1-3 An ultraviolet disinfection lamp 83 is installed in the secondary filter barrel 8, and a controller is installed on the outer wall of the secondary filter barrel 8, and the controller is used to control the start and stop of the ultraviolet disinfection lamp 83.
[0036] In this embodiment, during use, when the pump 81 draws the hospital sewage in the collection pipe 7 into the secondary filter barrel 8, the sewage will be initially blocked by the activated carbon filter plate 94, and the sewage waiting to be filtered in the secondary filter barrel 8 can be disinfected by the ultraviolet disinfection lamp 83. The ultraviolet disinfection lamp 83 can emit ultraviolet radiation to kill pathogens, bacteria, viruses and other microorganisms in the sewage; at the same time, ultraviolet radiation can destroy the nucleic acid structure of the microorganism, causing it to lose its biological activity, thereby achieving the disinfection effect.
[0037] Specifically, refer to Figure 1-3 A sedimentation tank 10 is provided on one side of the base 1, and the bottom of the secondary filter barrel 8 is connected to the sedimentation tank 10 through a conduit.
[0038] In this embodiment, the settling tank 10 can be used to collect hospital sewage, so that users can recycle and reuse the sewage.
[0039] Specifically, refer to Figure 1-3 A valve 82 is installed at the bottom of the secondary filter tank 8 , and the valve 82 is used to control the opening and closing of the connection between the secondary filter tank 8 and the sedimentation tank 10 .
[0040] In this embodiment, after the hospital sewage is disinfected by the ultraviolet disinfection lamp 83 and filtered through the activated carbon filter plate 94 and the particle filter layer 95, the user opens the valve 82 so that the disinfected and precipitated hospital sewage can enter the sedimentation tank 10 through the secondary filter barrel 8 to complete collection and re-sedimentation treatment.
[0041] The utility model of hospital sewage collection and disinfection device:
[0042] Step 1: When the user treats hospital sewage, the sewage to be treated is poured into the primary filter barrel 3. At this time, the sewage will be preliminarily filtered through the metal filter plate 4 to remove large impurities contained in the sewage, so as to facilitate subsequent disinfection treatment. Then, the sewage passes through the metal filter plate 4 and enters the gravel filter layer 5. At this time, under the preliminary filtration of the gravel filter layer 5, the solid particles and suspended matter in the hospital sewage can be preliminarily filtered;
[0043] Step 2: After the hospital sewage is filtered through the gravel filter layer 5, it will be filtered again through the metal filter plate 4 at the bottom of the gravel filter layer 5, and then enter the circulation pipe 6 and enter the collection pipe 7 through the circulation pipe 6. At this time, the user turns on the pump 81, and the pump 81 pumps the sewage in the collection pipe 7 to be pumped into the secondary filter barrel 8 for secondary filtration. At this time, the sewage entering the secondary filter barrel 8 can enter the particle filter layer 95 through the activated carbon filter plate 94. At this time, under the secondary filtration of the activated carbon filter plate 94 and the particle filter layer 95, the drug residues, chemical substances and organic wastes in the hospital sewage can be further filtered. At the same time, with the filtration of the metal filter plate 4 and the gravel filter layer 5, the hospital sewage can be thoroughly filtered and sterilized. At the same time, with the ultraviolet disinfection lamp 83 set in the secondary filter barrel 8, the ultraviolet disinfection lamp 83 can disinfect and sterilize the hospital sewage, thereby more effectively removing pollutants in the hospital sewage.
[0044] Step 3: After the hospital sewage is disinfected by the ultraviolet disinfection lamp 83 and filtered through the activated carbon filter plate 94 and the particle filter layer 95, the user opens the valve 82 so that the disinfected and precipitated hospital sewage can enter the sedimentation tank 10 through the secondary filter barrel 8 to complete collection and re-precipitation treatment.
