Description

Technical Field

[0001] This utility model relates to the field of medical wastewater technology, and in particular to a disinfection and purification structure for medical wastewater. Background Technology

[0002] With the continuous development of the medical industry, the safe treatment of medical wastewater has become a crucial link in safeguarding public health and the ecological environment. Medical wastewater contains a large number of pathogens, chemical agents, heavy metals, and other pollutants. If discharged directly without effective treatment, it will pose a serious threat to aquatic ecosystems and human health.

[0003] Currently, common medical wastewater disinfection and purification equipment on the market has many limitations. In the disinfection stage of some traditional treatment equipment, it is difficult to control the amount of disinfectant added. Excessive addition not only wastes resources but may also cause new environmental problems due to the generation of disinfection byproducts.

[0004] In addition, existing equipment has certain deficiencies in terms of structural design and functional integration. For example, the stirring components of some equipment have a single function, only playing a mixing role and failing to fully utilize the stirring process to enhance the treatment effect; the adsorption and filtration components are often fixed as an integral part of the housing, making it difficult to replace or maintain them according to actual usage, thus increasing the operating cost of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disinfection and purification structure for medical wastewater.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base plate, with supporting legs welded to the four corners of the top surface of the base plate. A housing 1 is welded to the top of the four supporting legs. A cover plate is bolted to the top of the housing 1, and a metering component is connected to the top of the cover plate. A stirring and adsorption component is connected inside the housing 1. A housing 2 is bolted to the center of the top surface of the base plate. Two mounting frames are detachably connected to the housing 2. A filter screen and an activated carbon adsorption screen 2 are bolted to the two mounting frames respectively. Ultraviolet disinfection lamps are installed on the inner surfaces of both sides of the housing 2. A pipe 2 is fixedly connected to the bottom wall of the housing 1, and the bottom end of the pipe 2 penetrates the top wall of the housing 2 and extends into the housing 2.

[0008] The metering component includes two support plates welded to the top surface of the cover plate. A transparent cartridge is fixed to the top of the two support plates by bolts. A scale line is connected to one side of the transparent cartridge. A pipe is fixedly connected to the bottom wall of the transparent cartridge. The bottom end of the pipe penetrates the bottom wall of the cover plate and extends into the box body.

[0009] As a further description of the above technical solution:

[0010] The stirring and adsorption assembly includes a motor that is bolted to the outer surface of the housing. The output shaft of the motor passes through one side wall of the housing and extends into the bottom plate, where a rotating rod is welded. The end of the rotating rod away from the motor is rotatably connected to the inner surface of the housing. Two stirring frames are bolted to the outer surface of the rotating rod, and activated carbon adsorption mesh is bolted to each of the two stirring frames.

[0011] As a further description of the above technical solution:

[0012] The inner bottom surface of the second housing has two slots, and the bottom ends of the two mounting frames are respectively engaged in the two slots. The top wall of the second housing has two through holes, and the top ends of the two mounting frames pass through the two through holes and extend to the outside of the second housing, and are each fixed with a connecting plate by bolts. The two connecting plates are connected to the top surface of the second housing by connecting components.

[0013] As a further description of the above technical solution:

[0014] The connecting assembly includes a fixing block welded to the top surface of the housing, a plug rod slidably connected through the fixing block, a plug hole opened on the connecting plate, one end of the plug rod being inserted into the plug hole, a pull block welded to the other end of the plug rod, and a return spring sleeved on the outside of the plug rod, with the two ends of the return spring being welded to the side of the pull block and the side of the fixing block, respectively.

[0030] Reference Figures 1-4 An embodiment of this utility model includes a base plate 1, with support legs 11 welded to the four corners of the top surface of the base plate 1. A box body 2 is welded to the top of the four support legs 11. A cover plate 4 is fixed to the top of the box body 2 by bolts. A quantitative component is connected to the top of the cover plate 4. A stirring and adsorption component is connected in the box body 2. A box body 20 is fixed to the middle of the top surface of the base plate 1 by bolts. Two mounting frames 17 are detachably connected in the box body 20. A filter screen 26 and an activated carbon adsorption screen 27 are fixed to the two mounting frames 17 by bolts, respectively. Ultraviolet disinfection lamps 24 are installed on the inner surfaces of both sides of the box body 20. A pipe 29 is fixedly connected to the bottom wall of the box body 2. The bottom end of the pipe 29 penetrates the top wall of the box body 20 and extends into the box body 20.

[0031] The metering component includes two support plates 7 welded to the top surface of the cover plate 4. A transparent cartridge 6 is bolted to the top of each support plate 7. A graduation line 16 is connected to one side of the transparent cartridge 6. The transparent cartridge 6 is used to store disinfectant. The transparent material, combined with the graduation line 16, allows operators to easily observe and control the amount of disinfectant stored. A pipe 8 is fixedly connected to the bottom wall of the transparent cartridge 6. The bottom end of the pipe 8 penetrates the bottom wall of the cover plate 4 and extends into the housing 2. The stirring and adsorption component includes a motor bolted to the outer surface of the housing 2. 3. The output shaft of motor 3 passes through the side wall of housing 2 and extends into the bottom plate 1, where a rotating rod 13 is welded. The end of the rotating rod 13 away from motor 3 is rotatably connected to the inner surface of housing 2. Two stirring frames 14 are fixed to the outer surface of the rotating rod 13 by bolts. Activated carbon adsorption mesh 15 is fixed to each of the two stirring frames 14 by bolts. Two slots 25 are opened on the inner bottom surface of housing 20. The bottom ends of two mounting frames 17 are respectively locked into the two slots 25. Two through holes are opened on the top wall of housing 20. The top of 17 passes through two through holes and extends to the outside of the second housing 10, and is fixed with connecting plates 22 by bolts. Connecting components are connected between the two connecting plates 22 and the top surface of the second housing 10. Each connecting component includes a fixing block 18 welded to the top surface of the second housing 10. A rod 21 is slidably connected through the fixing block 18. A hole 23 is provided on the connecting plate 22. One end of the rod 21 is inserted into the hole 23, and a pull block 19 is welded to the other end of the rod 21. A return spring 20 is sleeved on the outside of the rod 21. The return spring 20 provides a restoring force to ensure the stability of the connection. The two ends of the return spring 20 are welded to the side of the pull block 19 and the side of the fixing block 18, respectively. A water outlet pipe 12 is fixedly connected to the lower side wall of the second box 10. Valves are connected to the second pipe 9, the first pipe 8, and the water outlet pipe 12. A water inlet pipe 5 is connected to the cover plate 4. By opening the bolts on the cover plate 4, the cover plate 4 can be removed from the first box 2. Then, the activated carbon adsorption net 15, which is bolted to the stirring frame 14, can be disassembled and replaced.

[0032] Working principle: First, medical wastewater is poured into tank 2 through inlet pipe 5. Disinfectant is poured into transparent medicine container 6. Observe the scale line 16. When the disinfectant reaches the appropriate level, stop pouring. Then, open the valve on pipe 8 so that the disinfectant flows into tank 2 through pipe 8. This can control the amount of disinfectant added and avoid problems such as resource waste, by-product pollution and incomplete disinfection caused by excessive or insufficient disinfectant.

[0033] Next, the wastewater comes into contact with the disinfectant in tank 2. The motor 3 is then started, causing the rotating rod 13 to rotate. The rotating rod 13 drives the two stirring frames 14 and the activated carbon adsorption net 15 on the stirring frames 14 to rotate. This not only mixes the wastewater and disinfectant but also, with the help of the activated carbon adsorption net 15, which moves with the stirring frames 14 during the mixing process, increases the contact area with the wastewater. Through physical adsorption, some organic pollutants, odor substances, and some heavy metal ions in the wastewater are quickly removed. At the same time, the mixing effect of the wastewater and disinfectant is enhanced, accelerating the disinfection reaction process.

[0034] Subsequently, the wastewater, after preliminary disinfection and adsorption treatment, flows into tank 10 by opening the valve on pipe 29. In tank 210, activated carbon adsorption mesh 27 further exerts its deep adsorption effect, removing remaining small molecule organic matter, pigments, and some residual chemical agents from the wastewater, further purifying the water quality. Filter mesh 26 intercepts and filters larger particulate impurities remaining in the wastewater. Finally, ultraviolet disinfection lamp 24 is turned on, using ultraviolet light to destroy the DNA or RNA structure of pathogens (such as bacteria, viruses, fungi, etc.) in the wastewater, rendering them unable to reproduce and infect, thus completing the final disinfection treatment of the medical wastewater. The valve on outlet pipe 12 is then opened, and the treated medical wastewater that meets the standards can be discharged from outlet pipe 12.

[0035] Pull the lever 19 to move the insertion rod 21, causing the insertion rod 21 to move out of the insertion hole 23 on the connecting plate 22 and release the fixation. Then, pull the connecting plate 22 upwards, causing the connecting plate 22 to move the mounting frame 17 out of the housing 10. The filter screen 26 and activated carbon adsorption screen 27 can then be removed, making it easy to replace them flexibly according to actual use, reducing the maintenance cost and difficulty of the equipment.
