Description

City rubbish from cooking harmless treatment device

Technical field

The utility model belongs to technical field of waste treatment, specifically, is related to a kind of kitchen refuse processing apparatus.

Background technology

In the face of increasingly serious environmental problem and energy crisis, energy-saving and emission-reduction are all being advocated energetically in the whole world.It is especially right For the city rubbish from cooking for easily causing environmental pollution and therewith the rubbish from cooking process of the generation power consumption of association, how Energy-saving and emission-reduction transformation is carried out, those skilled in the art's problem demanding prompt solution is had become.

Include landfill, compost and burning currently for the processing mode of rubbish from cooking.Wherein, the effect of landfill is very slow, account for Ground is also wide, easily produce secondary pollution to underground water.It is organic fertilizer that compost is rubbish from cooking fermentation, but this mode need to The time wanted is longer, causes the efficiency comparison of garbage disposal low.In addition, although rubbish from cooking is heated by someone, with quickening Garbage decomposition, but this mode not only can be caused power consumption high because of heating to large-scale rubbish from cooking, and in kitchen It is unfavorable in the case that remaining rubbish temperature is too high that rubbish fermentation is organic fertilizer on the contrary.And the mode of burning rubbish from cooking is not only dirty Dye air, and invest larger.

A kind of refuse disposal system as disclosed in Chinese patent application 201310675228.6, which is included at garbage dewatering Reason equipment, garbage sorting equipment and incinerator, wherein, it is multiple that garbage dewatering processing equipment includes that distribution has thereon The cylinder of apopore, in cylinder and it is provided with the airduct of multiple air outlets towards apopore, connection drum inlet and enters Material device and the blower fan of connection airduct one end, incinerator include feed hopper at the top of body of heater, successively staggeredly pacify Downward-sloping and per layer the lower end being mounted in body of heater is located at next layer of upper end rubbish loading plate, the position of multiple through holes that gather In the combustion chamber of lower portion of furnace body and the exhanst gas outlet device of upper of furnace body side is arranged on, in organic matter rubbish via multiple rubbish During rubbish loading plate glides, the heat that combustion chambers burn rubbish is produced organic matter rubbish successively to carrying on rubbish loading plate Toasted, residual moisture in rubbish is dried, the rubbish for slipping down to combustion chamber is quickly burned.However, the patent is disclosed Refuse disposal system there is following or deficiency：(1), simply simply rubbish is burned, burning is not disclosed Garbage disposal situation afterwards；(2) waste incineration easily produces secondary pollution；(3) no reasonable recycling garbage energy, it is impossible to Realize the effect of energy-conserving and environment-protective.

And for example a kind of kitchen, rubbish from cooking handling process and its place disclosed in Chinese patent application 201510168637.6 The mixture of kitchen, rubbish from cooking is put in pretreatment pulverizer to enter Jing after the sorting of automatic sorting platform by reason system, the technique again Row is crushed, and the oil water mixture that the liquid phase mixture and size-reduced machine of Jing automatic sorting platforms are separated enters water-oil separating In equipment, water-oil separating is carried out, the water separated from oily water separating equipment is mutually needed through filtration treatment, is finally poured to live The form of filling water is discharged, and oil phase carries out bio-separation into bio-separation equipment, is finally made bio-oil；Preprocessed powder During kitchen, rubbish from cooking after broken machine crushing is as source of nutrition input polypide breeding production line, the polypide of saprogen is carried out Cultivation, the polypide that grows up carry out drying and processing in dryer, are then processed into the feeds such as poultry, fish, and polypide discards Thing and residue carry out degradation treatment, the material Jing after degraded, and a part is used for generating electricity in the form of biomass fuel, another portion The packing outward transport in the form of fertilizer is divided to use.However, processing system disclosed in the patent haves the shortcomings that following or deficiency： (1), processing cost is high, is related to substantial amounts of filtering separation device；(2) degradation time is very long, and treatment effeciency is low；(3) following process Process is numerous and diverse.

For another example a kind of restaurant garbage treating system disclosed in Chinese patent application 201510404242.1, including：Air heat Source pump, is heated to liquid and with liquid as heat-conducting medium；Solar thermal collector, with heat pipe, is produced by solar energy Heat is heated to the liquid in which；Heating jacket, with inner housing and shell body, the inner chamber that inner housing is formed is used for holding Changing food waste, forms exocoel between inner housing and shell body, the liquid that the outer wall around inner housing spirals is provided with exocoel Passage, heating jacket are provided with the first temperature sensor for stretching into inner chamber；Liquid line, connection air heat source pump, solar energy heating Device and heating jacket；Control device, controls the opening and closing of each magnetic valve on air heat source pump and liquid line.However, Restaurant garbage treating system disclosed in the patent haves the shortcomings that following or deficiency：(1) the extraneous heat energy that provides is needed to enter rubbish Row heating simultaneously makes inner chamber remain the temperature of suitable microbial reproduction, generates greater energy consumption；(2), garbage decomposition is fermented into Long for organic fertilizer process time, treatment effeciency is low；(5) the container floor space of decomposing and fermenting rubbish is big.

Therefore it provides it is a kind of can either effective process rubbish from cooking produce pollution problem can make full use of food waste rubbish again The city rubbish from cooking harmless treatment device of rubbish self energy becomes urgent problem in the industry.
