Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste liquid disinfection and recycling technology, and in particular to a device for disinfecting and recycling nursing waste liquid. Background Technology
[0002] As a key piece of equipment in the medical and nursing field for treating waste liquid, the disinfection and recycling device for nursing waste plays an important role in ensuring the safety of the medical environment and achieving the rational use of resources. During medical and nursing procedures, a large amount of waste liquid containing various pathogens, chemicals, and impurities is generated. If not properly treated, this will pose a serious threat to the environment and human health.
[0003] Currently, nursing waste liquid disinfection and recovery devices typically have the following main components:
[0004] 1. Collection container, used to store various waste liquids, with a certain capacity and leak-proof design to ensure the safety of waste liquids during the collection process;
[0005] 2. The conveying pipeline is responsible for transporting the waste liquid in the collection container to the subsequent treatment stage. Its material must be corrosion-resistant to ensure smooth transportation.
[0006] 3. Basic treatment unit, including simple filtration components, such as filter screens, which can filter out larger particulate impurities in waste liquid, and preliminary disinfection components, such as disinfection by adding a single chemical disinfectant.
[0007] Currently, various wastewater treatment devices for nursing care are available on the market. Some devices employ only a simple single-layer filtration structure, using a single filter to initially filter the wastewater and remove larger particulate impurities. Other devices use more traditional single disinfection methods, such as relying solely on chemical disinfectants or ultraviolet irradiation for disinfection. While some more advanced devices possess both filtration and disinfection functions, these two processes operate independently without a coordinated mechanism.
[0008] However, the existing medical wastewater treatment devices have many problems. In terms of filtration, simple single-layer filtration cannot effectively remove tiny particles, organic matter, and dissolved impurities from the wastewater. These impurities may interfere with the disinfection process, reducing efficiency and potentially damaging the equipment. Regarding disinfection methods, single-method chemical disinfection may leave disinfectant residue, causing secondary pollution. Furthermore, the independent filtration and disinfection systems cannot fully utilize their synergistic effect, resulting in poor overall treatment and failing to meet increasingly stringent medical wastewater treatment standards. The medical wastewater disinfection and recovery device proposed in this application employs a multi-layer filtration and multi-disinfection method synergistic design, which can more thoroughly remove various impurities from the wastewater, efficiently kill pathogens, reduce disinfectant residue, and improve the quality and efficiency of wastewater treatment, significantly enhancing the overall treatment quality and efficiency. Utility Model Content
[0009] To address the shortcomings of existing technologies, this utility model provides a disinfection and recycling device for nursing waste liquid. It solves the problem that simple single-layer filtration cannot effectively remove tiny particles, organic matter, and dissolved impurities from waste liquid, which may interfere with the disinfection effect and reduce the disinfection efficiency in subsequent disinfection processes. In terms of disinfection methods, single chemical disinfection may leave disinfectant residues, causing secondary pollution to the environment.
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A disinfection and recycling device for nursing waste liquid includes a housing with a waste liquid inlet on its upper surface. Inside the housing are a disinfectant storage tank for storing disinfectant, a water pump, a disinfection pool for centralized disinfection of waste liquid, and a recycling tank for storing disinfected waste liquid. Above the disinfection pool is a filter box containing a coarse filter, a fine filter, and an activated carbon adsorption screen. Below the filter box is a stirring rod. Above the disinfection pool is a spraying mechanism for spraying disinfectant. Ultraviolet lamps for auxiliary disinfection are located on both sides of the filter box.
[0012] Preferably, a connecting pipe is fixedly connected between the disinfection pool and the recycling tank, a valve is provided on the surface of the connecting pipe, a fixing rod is fixedly connected to the inner wall of the shell, a protective sleeve is fixedly connected to the front surface of the fixing rod, a servo motor is fixedly installed on the upper surface of the protective sleeve, the output shaft of the servo motor is fixedly connected to the connecting shaft on the stirring rod, and the connecting shaft fixed on the stirring rod is rotatably connected to the protective sleeve.
[0013] Preferably, a partition is fixedly connected inside the housing, two fixing blocks are fixedly connected to the surface of the spraying mechanism, both fixing blocks are fixedly connected to the partition, and fixing frames are fixedly connected to both the left and right sides of the filter box, with the two fixing frames respectively fixedly connected to two ultraviolet lamps and both fixedly connected to the inner wall of the housing.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Waste liquid flows into the activated carbon adsorption net. Activated carbon, with its strong adsorption performance, removes odors and some dissolved organic matter from the waste liquid, ensuring that the waste liquid entering the disinfection tank is as pure as possible. Multi-layer filtration reduces potential risks during storage and transportation, and also provides a better foundation for possible further treatment or recycling, reducing the workload and difficulty of subsequent treatment steps.
[0016] 2. The ultraviolet lamp emits high-intensity ultraviolet light to irradiate the waste liquid. Utilizing the bactericidal properties of ultraviolet light, it further kills various pathogens in the waste liquid. The device adopts a disinfection method that combines disinfectant spraying and ultraviolet irradiation. The disinfectant can destroy the cell structure and physiological function of microorganisms through chemical reactions, killing a large number of bacteria, viruses and other pathogens.

Furthermore, single-method chemical disinfection may leave disinfectant residue, causing secondary pollution to the environment. The overall approach is as follows:
[0026] To address the problems existing in the prior art, this utility model provides a disinfection and recycling device for nursing waste liquid, including a shell 1, a waste liquid inlet 2 on the upper surface of the shell 1, a disinfection liquid storage tank 3 for storing disinfectant, a water pump 9, a disinfection pool 5 for centralized disinfection of waste liquid, and a recycling tank 4 for storing disinfected waste liquid. A filter box 8 is installed above the disinfection pool 5, containing a coarse filter screen 11, a fine filter screen 12, and an activated carbon adsorption screen 13. A stirring rod 10 is installed below the filter box 8. A spraying mechanism 6 for spraying disinfectant is installed above the disinfection pool 5. Ultraviolet lamps 7 for auxiliary disinfection are installed on both sides of the filter box 8. Waste liquid generated during the nursing process... Waste liquid is collected and flows into the disinfection device through waste liquid inlet 2. The waste liquid flowing in from waste liquid inlet 2 first undergoes filtration treatment. The coarse filter 11 plays its role first, intercepting larger solid impurities such as cotton balls and gauze fragments. Then, it passes through the fine filter 12, where smaller particles are retained. Finally, the waste liquid flows into the activated carbon adsorption net 13. Activated carbon, with its strong adsorption properties, removes odors and some dissolved organic matter from the waste liquid, ensuring that the waste liquid entering the disinfection tank 5 is as pure as possible. Multi-layer filtration reduces potential risks during storage and transportation, and provides a better foundation for possible further treatment or recycling, reducing the workload and difficulty of subsequent treatment stages.

Two fixing blocks are fixedly connected to the surface of the spraying mechanism 6. Both fixing blocks are fixedly connected to the partition 19. Fixing frames 20 are fixedly connected to both sides of the filter box 8. The two fixing frames 20 are fixedly connected to two ultraviolet lamps 7 respectively and are fixedly connected to the inner wall of the shell 1. The waste liquid entering the disinfection tank 5 undergoes multi-directional disinfection treatment. Multiple nozzles on the spraying mechanism 6 are activated simultaneously to evenly spray the disinfectant from the disinfectant storage tank 3 into the waste liquid, allowing the disinfectant and waste liquid to mix initially. At the same time, the ultraviolet lamps... The external lamp 7 emits high-intensity ultraviolet light to irradiate the waste liquid.

The stirring device starts operating at a set speed, and the servo motor 14 starts to drive the stirring rod 10 to continuously agitate the waste liquid, so that the disinfectant and waste liquid are fully mixed, comprehensively improving the disinfection effect. After the disinfection reaction is completed, the valve 17 connected to the recovery tank 4 is opened, and the waste liquid flows into the recovery tank 4 by gravity. When further disposal of the treated waste liquid is required, it can be discharged through the outlet of the recovery tank 4 for reasonable recycling or other compliant treatment.

[0048] Working principle:
[0049] Wastewater generated during the nursing process is collected and flows into the disinfection device through wastewater inlet 2. The wastewater flowing in from inlet 2 first undergoes filtration. The coarse filter 11 intercepts larger solid impurities such as cotton balls and gauze fragments. Next, it passes through the fine filter 12, where smaller particles are retained. Finally, the wastewater flows into the activated carbon adsorption mesh 13. Activated carbon, with its strong adsorption properties, removes odors and some dissolved organic matter from the wastewater, ensuring that the wastewater entering the disinfection tank 5 is as pure as possible. Multi-layer filtration reduces potential risks during storage and transportation and provides a better foundation for possible further treatment or recycling, reducing the workload and difficulty of subsequent treatment stages. The wastewater entering the disinfection tank 5 undergoes multi-faceted disinfection treatment. Multiple nozzles on the spraying mechanism 6 are activated simultaneously, evenly spraying disinfectant from the disinfectant storage tank 3 into the wastewater, allowing the disinfectant to mix initially with the wastewater. Meanwhile... Ultraviolet lamp 7 emits high-intensity ultraviolet light to irradiate the waste liquid. Utilizing the bactericidal properties of ultraviolet light, it further kills various pathogens in the waste liquid. The device adopts a disinfection method that combines disinfectant spraying and ultraviolet irradiation. The disinfectant can destroy the cell structure and physiological function of microorganisms through chemical reactions, killing a large number of bacteria, viruses, and other pathogens. The shell 1 has a double-layer jacket design, with constant-temperature hot water flowing into the outer space to ensure that the space inside the shell 1 is always maintained within a suitable temperature range for disinfection. The stirring device starts operating at a set speed, and the servo motor 14 starts to drive the stirring rod 10 to continuously agitate the waste liquid, so that the disinfectant and waste liquid are fully mixed, comprehensively improving the disinfection effect. After the disinfection reaction is completed, the valve 17 connected to the recovery tank 4 is opened, and the waste liquid flows into the recovery tank 4 by gravity. When further disposal of the treated waste liquid is required, it can be discharged through the outlet of the recovery tank 4 for reasonable recycling or other compliant treatment.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
