[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-4The first embodiment is shown: a medical sewage micro-nano bubble sterilization device, comprising a sewage treatment tank 1, a support plate 11 is fixedly mounted on the top of the sewage treatment tank 1, and a supply mechanism is provided on the top of the support plate 11, the supply mechanism comprising:

[0027] The pipe assembly 2 is arranged on the top of the support plate 11. The pipe assembly 2 includes a main pipe 21. A first shell 22 is provided on the right side of the outer wall of the main pipe 21. A standpipe 23 is fixedly connected to the left side of the outer wall of the main pipe 21. A second shell 24 is provided on the outer wall of the standpipe 23.

[0028] The suction assembly 3 is arranged inside the pipeline assembly 2 and includes a first impeller 31, a first motor 32, and a second impeller 33. The first impeller 31 is mounted inside the first housing 22 via a rotating shaft, and the second impeller 33 is mounted inside the second housing 24 via a rotating shaft. A synchronous pulley set 34 is connected between the rotating shafts on the first motor 32 and the second impeller 33. The synchronous pulley set 34 is placed outside the pipeline assembly 2. The first motor 32 is mounted on the outer wall of the first housing 22 to drive the first impeller 31 to rotate.

[0029] The medicine dosing component 4 is arranged on the top of the pipeline component 2.

[0030] The first housing 22 and the second housing 24 provide installation space for the first impeller 31 and the second impeller 33, respectively, while ensuring the stability of the impellers during rotation. The riser 23 connects the main pipeline 21 and the drug dosing assembly 4, allowing the drug to smoothly enter the main pipeline 21 and mix with the sewage under the action of the pressure difference;

[0031] The first motor 32 is started to drive the first impeller 31 to rotate, causing a pressure difference inside the main pipe 21, thereby sucking medical sewage into the main pipe 21, realizing the automatic suction function of sewage without the need for additional pumping equipment. While the first impeller 31 rotates, it drives the second impeller 33 to rotate through the synchronous pulley group 34, so that a pressure difference is generated inside the riser 23, creating conditions for the suction of the medicine, ensuring that the medicine can smoothly enter the main pipe 21 and mix with the sewage, thereby improving the degree of automation and operating efficiency of the device.

[0032] The left end of the main pipeline 21 is fixedly connected to a sewage inlet pipe 25. Both the main pipeline 21 and the sewage inlet pipe 25 are installed on the top of the support plate 11 through a pipe clamp. The right end of the main pipeline 21 is installed with a sewage outlet pipe 26 extending to the inside of the sewage treatment tank 1. The sewage inlet pipe 25 is responsible for introducing external medical sewage into the main pipeline 21, and the sewage outlet pipe 26 transports the sewage mixed with the medicine to the sewage treatment tank 1.

[0033] The drug dosing component 4 includes a valve housing 41, which is installed at the top of the riser 23. A valve core 43 is provided inside the valve housing 41, and a second motor 42 for driving the valve core 43 to rotate is provided outside the valve housing 41. The second motor 42 is installed on the outer surface of the valve housing 41 through a U-shaped plate. The second motor 42 drives the valve core 43 to rotate. By controlling the opening of the valve core 43, the amount of drug entering the riser 23 from the drug hopper 5 through the valve housing 41 can be accurately controlled, thereby achieving mixing of the drug and sewage in a certain proportion in the pipeline component 2.

[0034] A medicine hopper 5 is installed on the top of the valve housing 41, and a support leg 51 is installed on the outer surface of the medicine hopper 5. The bottom of the support leg 51 is fixedly installed on the top of the support plate 11. The medicine hopper 5 is used to store medicine. The support legs 51 installed on its outer surface stably fix the medicine hopper 5 on the top of the support plate 11, ensuring the stability of the medicine supply and preventing the medicine hopper 5 from shaking or tipping over.

[0035] Figures 1-4 A second embodiment is shown, which mainly differs from the first embodiment in that a micro-nano bubble generator 6 is provided outside the sewage treatment tank 1, and an output end of the micro-nano bubble generator 6 is provided with a bubble output pipe 61 extending into the interior of the sewage treatment tank 1. The micro-nano bubble generator 6 can generate a large number of micro-nano bubbles, which enter the sewage treatment tank 1 through the bubble output pipe 61. The micro-nano bubbles have the characteristics of large specific surface area, high surface energy, and long residence time in water. During the rising process, they are in full contact with the mixture of sewage and chemicals. On the one hand, the micro-nano bubbles can increase the oxygen content in the sewage and provide conditions for some oxidation reactions; on the other hand, the high activity of the micro-nano bubble surface can promote the decomposition and diffusion of the chemical, enhancing the bactericidal effect of the chemical. At the same time, the micro-nano bubbles themselves can also produce physical destructive effects on pathogens in the sewage, such as cavitation, greatly improving the sterilization treatment ability of the sewage.

[0036] A drain pipe 12 is fixedly connected to the right surface of the sewage treatment tank 1 near the bottom, and a solenoid valve 13 is provided on the drain pipe 12. The drain pipe 12 is used to discharge the treated sewage out of the sewage treatment tank 1. It is arranged at a position near the bottom of the right surface of the sewage treatment tank 1, which is conducive to the complete discharge of the sewage. The solenoid valve 13 is installed on the drain pipe 12. By controlling the switch of the solenoid valve 13, the discharge time and discharge amount of the sewage can be conveniently controlled.
