Description
Technical field
The present invention relates to medical instrument garbage reclamation processing equipment technical fields, and in particular to medical waste is crushed burning side
Method.
Background technique
Medical waste refers to the waste that medical institutions generate in treatment and patient activity, usually has a large amount of bacterium
And virus, it is important hazardous waste, if dealing with improperly, secondary infection and environmental pollution will be caused, seriously affect people
Health.Especially hospital largely uses the instruments such as disposable syringe, infusion apparatus, gloves, aspirator, by providing these
Instrument should unmake, and specified unit centralized recovery is given after sterilized.The links such as stacking, collection, the transport of medical waste are reduced, to the greatest extent
Fast progress harmless treatment is one and protects hospital and social environment from the important measures of harm.It is wanted by international Basel Convention
It asks, medical waste is immovable high risk substance, should be solved on the spot.
Different types of processing mode, the World Health Organization (WHO) have been explored in processing of the people to medical waste at present
And European and American countries specify corresponding management measure and relevant treatment Countermeasures.It is new technology, new with the development of medical industry
Either in type very big variation still quantitatively all occurs for the appearance of product, new disease, medical waste, medical treatment
Dealing carefully with for rubbish seems even more important.
Currently, that there are closure is poor, bulky, burns to be not thorough and leads to secondary pollution for existing incinerator for medical garbage
And the disadvantages such as innoxious degree is low.
Using large-scale centralized incineration technology and equipment, is concentrated again from hospital or medical center collection and be transported to burning center concentration
It burns, is the disinfection that can solve medical waste, ruins the problem of type, volume reduction.But it establishes large-scale centralized burning center and brings one
Series of problems:
One, it is that hospital or medical center are dispersed in the very big area of area, is collected into one place and need largely
Dangerous Goods Transport ability;
It two, is to transport the cargo safety problems on the way of these highly dangerous it is still necessary to solve;
It three, is that large-scale burning facility can generate a large amount of poisonous and harmful substance such as when burning away the refuse: dioxin, nytron
Object, chloride etc., while a large amount of greenhouse gases and thermal pollution are generated, serious pollution environment.
Four, it is to solve the problems, such as garbage disposal by waste disposal fee is received, increases hospital and the expense of patient in this way,
The expense of finance is increased again.
Patent document CN107631302A discloses a kind of medical wastes incineration device with crushing function, and the document is public
The medical wastes incineration device opened also has crushing function, is crushed by gear tooth-type sieving approach device, then pass through vibration
Device drives connecting rod vibration, to drive bearer network to shake, so that the vibration of clinical waste is driven, to increase burning effect.
The gear tooth-type sieving approach device is unfavorable for burning after crushing clinical waste, regardless of the clinical waste of size
It requires to be crushed by crushing device, the clinical waste small relative to size, just will increase and be broken into this, and after crushing
Clinical waste be unfavorable for crushing, in order to increase burning effect, shaking device has been set in furnace, but in the furnace inner environment of high temperature
Setting shaking device is unpractical, in addition, the document is by being provided with slope property baffle, it is useless for controlling broken medical treatment
Object, which is flowed into, burns intracavitary portion, while preventing the exhaust gas for burning chamber burning generation from entering the inside of feeding device, to pollute
Air, but not can avoid the discharge of exhaust gas equally in the moment that property baffle in slope is opened.
Summary of the invention
