Description

Plastic medical waste recovery device

Technical Field

The invention relates to the technical field of medical waste treatment equipment, in particular to a plastic medical waste recovery device.

Background

Medical waste refers to contaminated waste that has contacted the blood and flesh of a patient. Such as used cotton balls, sandcloths, adhesive tapes, waste water, disposable medical devices, post-operative waste, expired drugs, and the like. According to the medical detection report of the national health department, the harmfulness of the virus and the germ of the medical garbage is dozens, hundreds or even thousands of times of that of the common household garbage because the medical garbage has the characteristics of space pollution, acute infection, latent pollution and the like. If the treatment is improper, serious pollution to the environment can be caused, and the treatment can also become a source of epidemic disease.

Medical plastic garbage is a main part of medical garbage, hospitals can generate a large amount of plastic medical garbage every day, the broad plastic definition refers to a material with plastic behavior, the plastic property refers to the state that the material is deformed when being acted by external force, and the material can still keep the stressed state after the external force is cancelled. The elastic modulus of the plastic is between that of rubber and fiber, and the plastic can deform to a certain extent under stress. Soft plastics are close to rubber and hard plastics are close to fibre. The term "plastic" as defined in the narrow sense means a material which is flowable and moldable during processing, comprising a resin (or a monomer directly polymerized during processing) as a main component and additives such as a plasticizer, a filler, a lubricant, and a colorant as auxiliary components. The treatment of plastic medical waste becomes an important work for hospitals, and usually, a great deal of plastic medical waste is accumulated in a garbage can, but the storage space of the garbage can is limited, a great deal of medical waste is easily filled when being guided into the garbage can, and the garbage is accumulated in other places, and also occupies a great deal of space, because the garbage in a fluffy state is large in size, the occupied space is also large, and the medical waste contains paper, plastic bags for packaging medicines or medicaments, and contains a great amount of bacteria and viruses, so that the treatment is difficult, and an effective treatment means is not available at present. The waste of plastics can not only be caused to these rubbish through not handling, still can cause the pollution of environment, and plastic refuse recovery unit can smash plastic refuse, but current plastic refuse recovery unit only sets up the one-level and smashes, smashes not enough evenly thoroughly, influences subsequent recovery processing. And a large amount of pathogenic bacteria are remained in the crushed plastic chips, so that the environmental pollution is serious.

In the prior art, the traditional landfill method and high-temperature incineration method are often adopted to recycle the plastic medical waste, so that not only is biological pollution easily caused and serious potential safety hazard exists, but also the plastic has extremely strong chemical inertness and is extremely difficult to decompose, the environment is damaged, and simultaneously, the plastic resources are greatly wasted; if a high-temperature incineration method is adopted, other toxic and harmful objects such as fly ash, dioxin and the like are easily generated, the environment can be seriously polluted, and on the other hand, great waste is generated by direct incineration, so that a novel medical waste recovery device is needed to be designed.
