Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment, in particular to a boiling heat storage type medical waste treatment device. Background Technique

[0002] At present, urban medical waste is basically treated by physical methods for centralized disinfection, sterilization and harmless treatment. Thermal sterilization is the mainstream, and radiation sterilization is auxiliary. Among them, thermal sterilization is mainly incineration, followed by steaming.

[0003] However, when using the incineration method for treatment, toxic and harmful substances such as dioxins are easily generated during the incineration process, polluting the atmospheric environment. Compared with the incineration method, although the steaming method is relatively environmentally friendly, its energy consumption and cost are also relatively high. When dealing with a large amount of medical waste, it is easy to cause a large amount of energy consumption and increase the treatment cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a boiling heat storage type medical waste treatment device to solve the above problems existing in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A boiling heat storage type medical waste treatment device includes an outer cabin and an inner cabin. A stirring component is arranged on one side surface of the inner cabin. A crushing box is arranged above the outer cabin. The bottom of the crushing box penetrates through the outer cabin and is communicated with the inside of the inner cabin. A crushing component is arranged inside the crushing box. The top of the inner cabin is communicated with a communicating pipe extending outside the outer cabin. A first valve is fixedly installed on the communicating pipe, and a feeding box is fixedly installed at the top end. Quicklime is placed inside the feeding box;

[0007] The stirring component includes a first motor fixedly installed on one side surface of the outer cabin. The output end of the first motor is fixedly installed with a rotating shaft extending into the inner cabin and rotatably connected to its inner wall. A plurality of curved stirring plates are fixedly installed on the surface of the rotating shaft;

[0008] The crushing component includes two second motors fixedly installed on one side surface of the crushing box. The output ends of the second motors both extend into the crushing box and are rotatably connected with crushing rollers. The two crushing rollers are meshed with each other.

[0009] The beneficial effects of the present utility model are as follows: When medical waste enters the crushing box, two second motors drive the crushing rollers to move, enabling the crushing rollers to mechanically crush the medical waste. The crushed medical waste enters the interior of the inner chamber. The first motor drives the rotating shaft to rotate, causing the stirring plates to perform high-speed stirring on the medical waste. Through the high-speed rotation of the machinery, intense mixing and contact occur between the waste particles and between the waste and the medium inside the chamber (such as steam, hot air, etc.). This mixing and contact process causes the moisture in the waste to rapidly evaporate, forming a boiling-like phenomenon. At the same time, the waste particles are fully dispersed and refined, forming a fluidized state. During this process, the mechanical heat energy generated can sterilize the medical waste; when the stirring plates are stirring, the first valve is activated, enabling the quicklime in the feeding box to automatically enter the interior of the inner chamber. Quicklime belongs to basic oxides, and the hydration reaction of quicklime to form calcium hydroxide is also a strongly basic substance. In an over-alkaline environment, the cell walls and membrane structures of microorganisms are extremely easily damaged, and the substances inside the cells are lost, causing pathogens such as bacteria and viruses to lose their ability to survive and reproduce, thereby killing the microorganisms; at the same time, a large amount of heat is released during the reaction of quicklime with water. Combining with the heat generated by mechanical boiling, it directly heats the medical waste. Utilizing the dual effects of temperature (heat energy) and chemical disinfectant (calcium hydroxide), through boiling mixing, the bacteria-carrying bodies directly interact with the disinfection source, quickly disinfecting and sterilizing. During this process, no additional harmful gases or wastewater are generated, reducing environmental pollution. At the same time, the heat used in the above treatment process comes from chemical reactions and mechanical boiling, without the need for external energy sources, reducing energy consumption and treatment costs.

[0010] Based on the above technical solutions, the present utility model can be further improved as follows.

[0011] Further, a conveying channel is fixedly installed at the top of the crushing box. A second valve is fixedly installed on the conveying channel, and a storage box is fixedly installed at the top end. An outlet channel is connected to the bottom of the inner chamber, and a third valve is fixedly installed on the outlet channel.

[0012] Further, several water replenishing pipes extending to the outer chamber are connected to the inner chamber.

[0013] Further, several temperature sensors are fixedly installed on the inner wall of the inner chamber.

[0014] Further, a liquid replenishing pipe extending to the inner chamber is connected to the outer chamber.

[0015] Further, several support rods with one end fixedly installed on the surface of the inner chamber and the other end fixedly connected to the inner wall of the outer chamber are fixedly installed. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the crushing box 5 penetrates through the outer cabin 1 and is communicated with the inside of the inner cabin 2. A crushing assembly 6 is arranged inside the crushing box 5. The top of the inner cabin 2 is communicated with a connecting pipeline 7 extending outside the outer cabin 1. A first valve 8 is fixedly installed on the connecting pipeline 7, and a feeding box 9 is fixedly installed at the top end. Quicklime is placed inside the feeding box 9;

[0023] The stirring assembly 4 includes a first motor 41 fixedly installed on one side surface of the outer cabin 1.

The output ends of the second motors 61 both extend into the crushing box 5 and are rotatably connected with crushing rollers 62. The two crushing rollers 62 are meshed with each other.

[0025] When medical waste enters the crushing box 5, two second motors 61 drive the crushing rollers 62 to move, enabling the crushing rollers 62 to mechanically crush the medical waste. The crushed medical waste enters the inner chamber 2. The first motor 41 drives the rotating shaft 42 to rotate, causing the stirring plates 43 to perform high-speed stirring on the medical waste. Through the high-speed rotation of the machinery, intense mixing and contact occur between the waste particles and between the waste and the medium in the chamber (such as steam, hot air, etc.). This mixing and contact process causes the moisture in the waste to rapidly evaporate, forming a boiling-like phenomenon. At the same time, the waste particles are fully dispersed and refined, forming a fluidized state. During this process, the mechanical heat energy generated can sterilize the medical waste; when the stirring plates 43 are stirring, the first valve 8 is activated, enabling the quicklime in the feeding box 9 to automatically enter the inner chamber 2. Quicklime belongs to basic oxides, and the hydration reaction of quicklime to form calcium hydroxide is also a strongly basic substance. In an over-alkaline environment, the cell walls and membrane structures of microorganisms are extremely easily damaged, and the substances inside the cells are lost, causing pathogens such as bacteria and viruses to lose their ability to survive and reproduce, thereby killing the microorganisms; at the same time, a large amount of heat is released during the reaction of quicklime with water. Combining with the heat generated by mechanical boiling, it directly heats the medical waste. Utilizing the dual effects of temperature (heat energy) and chemical disinfectant (calcium hydroxide), through boiling mixing, the bacteria-carrying bodies directly interact with the disinfection source, quickly disinfecting and sterilizing. During this process, no additional harmful gases or wastewater are generated, reducing environmental pollution. At the same time, the heat used in the above treatment process comes from chemical reactions and mechanical boiling, without the need for external energy, reducing energy consumption and treatment costs.
