Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a disinfection device for hospital wastewater. Background Technology

[0002] Wastewater from medical institutions contains some special pollutants, such as drugs, disinfectants, diagnostic reagents, as well as a large number of pathogenic microorganisms, parasite eggs, and various viruses, including roundworm eggs, hepatitis viruses, and tuberculosis bacteria. Therefore, it is necessary to carry out disinfection through professional treatment processes to ensure that the wastewater meets the discharge standards and avoids the risk of pathogen transmission and environmental pollution.

[0003] Application No. 202420367036.2 discloses a medical wastewater disinfection treatment device, including a box body. A filter screen is fixedly connected to the inner wall of the box body. Quartz stone is placed inside the filter screen. By placing quartz stone inside the filter screen, the wastewater is filtered and heavy metals in the wastewater are adsorbed. The disinfection box is equipped with a blowing device and an ozone device. By controlling the start of motor B, the rotating rod is driven to rotate, which drives the fan blade to rotate, generating wind energy. The ozone in the ozone box is then discharged into pipe B through pipe C. The wind energy generated by the rotating fan blade blows the ozone into the interior of the disinfection box, thereby disinfecting the wastewater inside the disinfection box to meet the discharge standards. Finally, by opening the valve, the disinfected wastewater is discharged to a designated area through the drain pipe.

[0004] The above-mentioned solution has shortcomings in use. When wastewater flows through the filter screen, the bacteria it carries will attach to the filter screen pores and form a biofilm. As a result, when subsequent wastewater flows through the filter screen, the bacteria in the biofilm will be continuously released into the water, causing the total number of colonies in the wastewater to increase compared to the original water, thus affecting the subsequent disinfection effect. Therefore, we provide a disinfection device for hospital wastewater. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1 With appendix Figure 2The image shows a disinfection device for hospital wastewater, comprising a treatment tank 1. An injection pipe 3 is connected to the outer surface of the treatment tank 1, and a sealing plug is provided at the top of the injection pipe 3. Disinfectant can be added to the inside of the treatment tank 1 through the injection pipe 3, and the sealing plug can seal the injection pipe 3 to prevent debris from falling in. The treatment tank 1 has an internal stirring structure, including a motor 5 installed on one side of the treatment tank 1. A rotating rod 7 is fixedly connected to the output end of the motor 5, and the other end of the rotating rod 7 extends into the inside of the treatment tank 1 and is rotatably connected to its inner wall. A set of stirring plates 6 is fixedly connected to the outer surface of the rotating rod 7. The operation of the motor 5 allows the rotating rod 7 to drive the stirring plates 6 to rotate, thereby uniformly stirring and mixing the wastewater and disinfectant mixture, further improving the disinfection effect of the wastewater. A support frame 4 is installed on the bottom surface of the treatment tank 1, and the bottom surface of the support frame 4 is provided with anti-slip texture. The support frame 4 can stably support the treatment tank 1 and facilitate the discharge of wastewater from the bottom discharge pipe of the treatment tank 1.

[0027] As attached Figure 1 With appendix Figure 2 As shown: A conveying assembly 2 for conveying wastewater into the treatment tank 1 is provided above the treatment tank 1. The conveying assembly 2 includes a set of inlet pipes 201 connected to the top of the treatment tank 1. Each inlet pipe 201 is equipped with a filter screen inside. A connecting cover 202 is fixedly connected to the top of each inlet pipe 201. The conveying assembly 2 also includes a conveying structure for conveying wastewater to the inlet pipes 201 at different locations. The conveying structure includes a sealed shell 203 installed on the top of the treatment tank 1. A water supply pipe 204 is rotatably connected to the upper surface of the sealed shell 203. An ultraviolet germicidal lamp 205 is installed on the outer surface of the water supply pipe 204. By injecting wastewater into the water supply pipe 204, the wastewater will flow into the inlet pipe 201. The filter screen inside the inlet pipe 201 can filter the wastewater. At the same time, the ultraviolet germicidal lamp 205 will irradiate and sterilize the filter screen inside the other inlet pipe 201.

[0028] As attached Figure 1 Appendix Figure 3 With appendix Figure 4As shown: A motor 206 is installed on the inner top wall of the sealed shell 203. A gear 207 is fixedly connected to the output end of the motor 206. A gear ring 208 meshes with the outside of the gear 207. The inner ring of the gear ring 208 is connected to the outer surface of the water supply pipe 204. An electric push rod 209 is installed on the outer surface of the water supply pipe 204. A sealed cover 211 is installed on the telescopic end of the electric push rod 209. The top of the sealed cover 211 and the output end of the water supply pipe 204 are connected by a telescopic pipe 210. When the inlet pipe 201 transports wastewater for a certain period of time, the electric push rod 209 is controlled to retract. The sealed cover 211 moves upward, controlling the motor 206 to work. The gear 207 drives the gear ring 208 to rotate half a turn, so that the inlet pipe 201 is precisely aligned with another inlet pipe 201. Then, the electric push rod 209 is extended, so that the sealed cover 211 is connected to the connecting cover 202. At the same time, the ultraviolet germicidal lamp 205 will deflect half a turn and be above the used inlet pipe 201, which can irradiate and sterilize the filter screen inside the inlet pipe 201. This can effectively reduce the amount of bacteria remaining on the filter screen during subsequent wastewater treatment, thereby ensuring the disinfection effect of subsequent wastewater.

[0029] As attached Figure 5 As shown: The inner top wall of the sealed shell 203 is provided with an annular groove 212. The inner wall of the annular groove 212 is slidably connected to a limiting rod 213. The bottom end of the limiting rod 213 is connected to the outer surface of the water supply pipe 204. By using the cooperation of the annular groove 212 and the limiting rod 213, the rotation of the water supply pipe 204 can be limited, which can ensure that the ultraviolet germicidal lamp 205 and the sealed cover 211 can be accurately positioned above the water inlet pipe 201 after deflection, thereby ensuring the accuracy of wastewater transportation and ensuring accurate radiation sterilization of the filter screen inside the water inlet pipe 201.

[0030] Working principle: First, the PLC controls the device to work at a time. The electric push rod 209 is started to extend, so that the sealed cover 211 and the connecting cover 202 are connected. At this time, the wastewater enters the inlet pipe 201 through the water supply pipe 204. After being initially filtered by the filter screen inside the inlet pipe 201, it falls freely into the treatment tank 1. Then, sodium hypochlorite disinfectant is added through the injection pipe 3. The motor 5 is started to drive the rotating rod 7 to rotate. The stirring plate 6 will mix and disinfect the wastewater and sodium hypochlorite disinfectant.

[0031] When a single inlet pipe 201 has been transporting wastewater for a certain period of time, the electric push rod 209 is retracted, the sealed cover 211 moves upward, the motor 206 is activated, and the gear ring 208 is driven to rotate half a turn through the gear 207, so that the inlet pipe 201 is precisely aligned with another inlet pipe 201. Then, the electric push rod 209 is extended, so that the sealed cover 211 is connected to the connecting cover 202. At the same time, the ultraviolet germicidal lamp 205 will deflect half a turn and be positioned above the used inlet pipe 201, so as to irradiate and sterilize the filter screen inside the inlet pipe 201. By changing the water supply position of the water supply pipe 204 at regular intervals through the above operations, the amount of bacteria remaining on the filter screen during subsequent wastewater treatment can be effectively reduced, thereby ensuring the disinfection effect of subsequent wastewater.
