The utility model discloses a theory of operation does:

as shown in fig. 5, it is a working principle diagram of the integrated medical waste harmless disposal complete equipment provided by the utility model. The first step of the treatment is to add the treated waste into the disinfection box (without pre-classification, crushing and the like), then close the box cover of the disinfection box, select an automatic mode to start the equipment, start the metering device at this time, spray a certain amount (adjustable) of disinfection solution into the disinfection box, start the rotation of the rotary knife set 21 at the bottom of the disinfection box, and gradually increase the rotation speed to 950-1000 r.p.m. Due to the rotation of the rotary knife group 21, the waste is vigorously stirred and crushed, and the mechanical energy is converted into heat energy due to the cutting, collision, extrusion and friction of the waste, so that the temperature of the waste is continuously increased until 135-155 ℃ is set by a program due to a large amount of heat generated by the conversion. At this time, the water content of the material is completely evaporated and extremely dried, and under the dual action of the disinfectant and high temperature, most of fungi, bacterial propagules, viruses and bacterial spores in the material are killed, and the cell tissues of the surviving bacteria and bacterial spores are dehydrated. Then the water is injected into the disinfection box in a controllable way, and the water is fully contacted with the surface of the object at high temperature and the evaporant, so that the same effect as the wet heating disinfection is produced (but the pressure in the disinfection box is not increased). This is done by having the properties of high temperature, liquid water and steam at the surface of the waste. After the dehydrated bacteria and cells of bacterial spores absorb water, the water is rapidly vaporized under the action of high temperature, so that the cells are expanded and broken, and the bacteria are thoroughly killed. Because the rotary knife group 21 fully crushes and mixes the wastes, the states of the wastes at all parts in the sterilizing box are the same, and the same disposal effect is achieved. The real-time measurement of the temperature and the injection of water are determined by the infrared radiation emitted by the waste. Therefore, the whole disposal process is safe and reliable, and the disposal flow can be controlled and regenerated. At the end of the treatment, the waste is cooled to around 105 ℃ by controlled water injection (the water will be substantially evaporated). The dried output after disposal is then automatically discharged by centrifugal force through a discharge valve 26 at the bottom of the sterilization chamber. The water vapor generated in the treatment process is condensed and absorbed by the steam condensing and absorbing device 3. The condensed water and the cooling water are discharged to a drainage system or sent to a water circulation system, and the dry air is discharged after reaching the standard after being treated by the gas filtering and adsorbing device 2. The whole system is in a negative pressure state (-200Pa) during the complete cycle operation of the disinfection box device 1, which is of great significance because in the case of a failure of the system seal, in the worst case, gas can only leak from the outside to the inside of the container without reverse leakage, thereby avoiding the biochemical risk to surrounding personnel caused by the leakage of steam generated during the disposal process.

The utility model discloses a total control mode adopts PLC program control, is equipped with manual and automatic operation mode. The reaction time of the control system is real-time detection control. The sterilization mode is mainly high-temperature (155 ℃) sterilization and is assisted by disinfection liquid sterilization. The heating mode is as follows: the energy is input into electric energy-mechanical-heat energy by a variable-frequency speed regulating motor 13 and is realized by stirring materials by a high-speed rotating cutter set to generate friction, extrusion, collision and cutting. The change form of the materials before and after treatment is as follows: the physical change is that the product is granular solid with the size of 3-5 mm, the volume is reduced by about 70 percent, and the weight is reduced by about 30 percent (depending on the moisture content of the treated material). Filtration efficiency of air filter: not less than 99.999 percent.

The utility model has the advantages of simple structure, compact, integrated into one piece, area is little, easily operation, be convenient for maintain, the maintenance, collect the windrow, throw the material, it is broken, the disinfection, the sterilization, it is dry, the ejection of compact is in an organic whole, adopt high temperature and assist the antiseptic solution to disinfect, the sterilization, the dehydration, deodorization, it is effectual to disinfect, it is efficient to deal with, field operation personnel are few, energy consumption is little, the running cost is low, waste residue after handling can regard as ordinary rubbish discharge to reach standard, can not cause secondary pollution to the environment, not only can wide application in to the infectivity that produces at different levels medical health mechanism and people in production, the harmful solid medical waste carries out innoxious the processing, still can be used to deal with general solid waste in the city, wide application prospect has, and the popularization and application is.
