Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] like Figure 1 As shown, this utility model provides a medical waste turnover box cleaning and disinfection machine, including an inlet section 1, a pre-washing section 2, a main washing section 3, a cleaning section 4, an air-drying section 5, and an outlet section 6, which are arranged sequentially. The inlet section 1 and the outlet section 6 are provided with inclined conveying channels, and the turnover boxes move sequentially along each section via a conveying mechanism 10. The conveying mechanism 10 mainly includes a set of drive rollers and a circulating conveyor belt installed inside the machine body. The conveyor belt is composed of multiple parallel stainless steel crossbars, forming a grid-like structure. Both ends are wound around the front and rear sets of rollers to form a closed loop. One end of the roller is connected to a motor, which provides power to achieve continuous rotation, driving the entire metal conveyor belt. Limiting guide rods 101 are provided on both sides of the conveyor belt to prevent the turnover boxes from shifting or tilting during operation.

[0023] The pre-wash section 2, main wash section 3, and clean wash section 4 are all equipped with spray units 7 and corresponding water tanks 8. Specifically, as follows... Figure 3 As shown, the spray assembly 7 includes multiple hollow tubes 71 arranged in a rectangular frame along the circumference of the cleaning channel. Multiple nozzles 72 are spaced apart on the upper, lower, and left and right outer walls of each hollow tube 71 to achieve multi-directional spraying of the outer surface of the turnover box.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, each of the pre-wash section 2, main wash section 3, and cleaning section 4 has an independent water tank 8 below it. Each water tank 8 is equipped with a manual valve 11, which is located at both ends of the connecting pipe between two adjacent water tanks. Liquid exchange between the water tanks is only possible when both valves of adjacent water tanks are open, allowing for liquid regulation or unified discharge under specific operating conditions. During normal operation, the liquids between the water tanks are not directly connected to ensure the independent functional zones of the pre-wash, disinfection, and cleaning sections. Each water tank receives the circulating liquid returning from the corresponding spray assembly 7 and filters, heats, and re-transports it. Each water tank has an inlet 81 on one side for replenishing with external clean water or disinfectant. A circulation pump interface 82 is located at the bottom of the water tank, connected to a circulation pump 9 via a pipe, enabling liquid return and closed-loop liquid supply to the spray system. The bottom of the water tank is equipped with a drain outlet 83 and a drain valve 84 for quickly draining residual liquid when changing the water source or cleaning debris. The drain valve is manually controlled, allowing operators to periodically remove sediment. To prevent large particulate contaminants from entering the water tank, a removable filter screen 85 is installed at the top opening for preliminary filtration of the return liquid, ensuring the cleanliness of the downstream circulation system. Furthermore, to meet the high-temperature cleaning requirements under certain conditions, only the water tanks corresponding to the pre-wash section 2 and the cleaning section 4 are equipped with steam heating. Steam inlets 87 are located on their side walls for introducing steam, while steam heating pipes 88 are located inside the water tank. When steam enters the steam heating pipes 88, it indirectly heats the water, thereby increasing the overall cleaning temperature. Simultaneously, the water tank 8 corresponding to the pre-wash section 2 is equipped with an overflow outlet 86. When the water level in the tank is too high, the overflow outlet 86 can drain excess liquid, preventing overflow due to abnormal water filling or spraying.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the circulating pump 9 is located on the side of the water tank 8, and its inlet is connected to the water tank 8 through the circulating pump interface 82. It is used to draw the filtered liquid from the water tank. After the circulating pump 9 starts, it pressurizes the cleaning solution or disinfectant in the water tank 8 and outputs it through the connecting pipeline to the spray assembly 7 above. After the liquid enters the hollow tube 71, it is sprayed out through the nozzle 72, forming a multi-directional spray on the surface of the turnover box. During the spraying process, the liquid flows down along the surface of the turnover box and finally falls back into the corresponding section of the water tank 8, realizing the recovery and circulation of the cleaning solution.

[0026] like Figure 1As shown, the drying section 5 is used to dry the cleaned turnover boxes. The drying section 5 is equipped with a fan 51 and air knives 52. The fan 51 is a centrifugal fan, and the air knives 52 include an upper air knife and left and right side air knives, which are arranged at intervals along the conveying direction of the conveying mechanism 10. The upper air knife blows downward to clean the top surface of the turnover box, and the left and right air knives blow inward to dry the side walls of the turnover box. The air outlet of the air knife 52 is connected to the fan 51 to output a high-speed airflow to dry the residual liquid on the surface of the turnover box.

[0027] like Figure 1 As shown, the circulating pump 9 is a horizontal stainless steel centrifugal water pump. Specifically, the pre-wash section 2 serves as a water spray section, used for preliminary rinsing of the turnover boxes to remove surface impurities and liquid residue. The circulating pump 9 is a hot alkaline water pump with a power of approximately 1.5kW, and can be configured for hot water cleaning as needed. The main wash section 3 serves as a disinfectant spray section. Its circulating system is connected to a water tank 8 containing a prepared disinfectant solution, usually a sodium hypochlorite solution mixed in a specific ratio. During operation, the operator adds the disinfectant solution to the water tank at a set concentration to ensure a stable and reliable concentration. The circulating pump 9 is a disinfectant water pump with a power of 0.75kW. The final wash section 4 is a clean water spray section, mainly used to thoroughly rinse away any residual alkaline solution or disinfectant solution from the surface of the turnover boxes. The circulating pump 9 is a hot water pump with a power of 5.5kW, and hot water spraying can be controlled according to set conditions. Through the above functional segmentation and circulating pump configuration, a multi-stage cleaning process from pre-washing to disinfection to final wash is achieved. Each liquid circulation system is independent, with a clear cleaning purpose and efficient process.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
