S4, secondary purification, namely conveying the medical waste conveyed by a conveying auger of the primary purification mechanism after the materials enter the primary purification mechanism, conveying the medical waste from front to back along the axial direction of the operation cavity under the action of wind pressure driving and conveying by the conveying auger, forcibly freezing and cooling the medical waste by an air cooler in the conveying process, increasing the brittleness of the medical waste, sterilizing and inactivating the medical waste at low temperature, crushing the medical waste subjected to freezing and embrittlement by a crushing mechanism, crushing nonmetallic materials and liquid materials in the medical waste to obtain small-particle-size waste, keeping a larger volume of the metallic materials in the medical waste, intensively conveying the crushed materials into a solid-liquid separation mechanism, and forcibly separating the liquid materials and solid physics in the medical waste;
s5, classifying and disposing, namely directly conveying the liquid materials subjected to solid-liquid separation into a liquid storage tank of a separation storage mechanism, conveying the liquid materials into a material separation cavity of the separation storage mechanism through solid wastes, magnetically adsorbing and fixing the metal materials by an adsorption electromagnet of the material separation cavity, forming a negative pressure environment and ascending air flow in a bearing cavity by utilizing a negative pressure fan and a drainage fan, blowing up nonmetallic material particles with light specific gravity in the solid materials and falling into a collecting pipe, finally conveying the nonmetallic material particles into a nonmetallic storage tank through a nonmetallic material outlet by the collecting pipe, stopping the cooperation operation of the negative pressure fan and the drainage fan after classifying and collecting the nonmetallic materials, simultaneously stopping conveying the materials into the bearing cavity, then stopping adsorbing the metal materials by the adsorption electromagnet, conveying the metal materials into the metallic storage tank through the metallic material outlet under the driving of an ultrasonic oscillator and the airflow of the drainage fan, thus completing classifying and storing the materials, and continuously conveying the subsequent materials into the material separation cavity for separating the materials after completing classifying and storing the materials; meanwhile, air flow generated in the material separation and conveying process is purified through an air purifying mechanism, and the purified air is returned to the primary purifying mechanism, the separation and storage mechanism and the conveying pipeline for recycling; in addition, the metal storage tank, the nonmetal storage tank, the liquid storage tank and the air purifying mechanism are driven to be replaced through the conveyor.
10. The method of claim 9, wherein in step S1, when the preliminary purification mechanism is set, 1-2 preliminary purification mechanisms are respectively set in each building structure and each individual building structure when the medical practice place is any one of a multi-layer building and a single-layer large-area building group.
