Description

Screening equipment for stored garbage of sanitary landfill

Technical Field

The utility model relates to a refuse treatment technical field, in particular to screening equipment of sanitary landfill stock rubbish.

Background

The storage capacity of the sanitary landfill is large, the garbage components are complex, and the humidity of the stored garbage is relatively low because the garbage is better distributed with rain and sewage. The method is characterized in that the method is used for treating the stored garbage in China at the starting stage, and the current treatment schemes mainly comprise three types, namely in-situ closing treatment, full-transfer remote treatment and incineration treatment.

The in-situ block disposal scheme enables the discharge of pollutants in landfills to be changed from past natural discharge to discharge that can be controlled. However, in the refuse landfill of the in-situ sealing, the time period for finishing the degradation of the organic matters reaches more than 50 years, the pollution persists, the site is not favorable for timely reuse, and the land utilization value after sealing is limited.

The whole-volume transferring and off-site disposal means that the garbage stocks in the garbage landfill are directly transferred to other places without treatment and then are subjected to related disposal or utilization after being excavated. The method thoroughly eliminates the potential safety hazard of the original refuse landfill, recovers the full utilization value of the original land, and enables the upright original refuse landfill to be developed and utilized as soon as possible. But the investment is large, the clearing and treatment cost is high, the application range is limited, and new land resources are occupied. Along with the higher and higher requirements of the society on the sanitary environment and the more and more scarce land resources, the requirements of site selection and new construction of landfill sites are more and more strict, so that the scheme is difficult to implement.

The incineration treatment refers to the treatment of directly sending the excavated garbage to a garbage incineration power plant, the soil content of the stored garbage is high, the heat value is low, the stored garbage which is not subjected to screening treatment is not suitable for direct incineration in an incineration plant, and only the stored garbage which is subjected to front-end treatment can be sent to the incineration plant for treatment. At present, the site selection of an incineration plant is difficult, the landing is slow, the daily garbage treatment requirement is difficult to meet, the effective classification cannot be realized, and the incineration treatment difficulty of the stored garbage is high.

SUMMERY OF THE UTILITY MODEL

For at least one among the above-mentioned technical problem of solution, with the effective classification of stock rubbish, the utility model provides a screening equipment of sanitary landfill stock rubbish, the technical scheme who adopts as follows:

the utility model provides a sanitary landfill stock rubbish divide sieve equipment includes one-level drum sieve, dish formula sorter and wind-force sorter, the one-level bin outlet that the one-level drum sieve was used for discharging oversize thing feeds through to wind-force sorter, the one-level discharge gate that the one-level drum sieve was used for discharging undersize thing feeds through to dish formula sorter, the first discharge gate that dish formula sorter was used for discharging oversize thing feeds through to wind-force sorter, wind-force sorter has the export of discharge heavy matter and the export of discharge light matter.

Furthermore, the sieve pores of the first-stage rotary screen are larger than those of the disc type separator.

Further, an outlet for discharging heavy materials and an outlet for discharging light materials in the wind power separator are respectively provided with a conveying belt.

Has the advantages that: through one-level drum sieve, dish-type sorter and wind separator with three kinds of rubbish such as stock rubbish effective divide into fine soil, aggregate and combustible substance, improve stock rubbish's sorting rate, the utility model discloses but wide application in refuse treatment technical field.

Detailed Description

The present invention will be further described with reference to fig. 1 to 2.

The utility model relates to a screening equipment of sanitary landfill stock rubbish, the process of screening stock rubbish is as follows: stabilizing the garbage pile, digging and transporting the garbage, crushing large garbage, vibrating to break up the garbage, sieving fine soil garbage, sieving aggregate garbage and packing the combustible materials.

The screening equipment comprises a primary rotary screen 11, a disc type sorting machine 12 and a wind power sorting machine 13, and further comprises a crusher, a vibration scattering machine and a horizontal bundling machine, wherein the crusher and the vibration scattering machine are arranged at the front end of the primary rotary screen 11, and the horizontal bundling machine is arranged at the rear end of the wind power sorting machine 13.

The first-stage rotary screen 11 is used for discharging a first-stage discharge port of undersize materials and communicating to the disc type sorting machine 12, the first discharge port of the disc type sorting machine 12 used for discharging oversize materials and communicating to the wind power sorting machine 13, and the first-stage rotary screen 11 is used for discharging a first-stage discharge port of the oversize materials and communicating to the wind power sorting machine 13.

The screen holes of the first-stage drum screen 11 are larger than those of the disc-type separator 12, the oversize products of the first-stage drum screen 11 are bricks, stones, plastics and the like with the grain size of more than 40mm, and the undersize products are humus with the grain size of less than 40 mm. The undersize of the disc classifier 12 is fine earth with a particle size of less than 10mm, and the balance is oversize, such as granular aggregate and lightweight RDF.

The wind power sorting machine 13 is provided with an outlet for discharging heavy materials and an outlet for discharging light materials, conveying belts are respectively arranged at the outlet for discharging the heavy materials and the outlet for discharging the light materials in the wind power sorting machine 13, the heavy materials are conveyed to a bone material pool through the conveying belts, and the light materials are conveyed to a horizontal binding machine through the conveying belts to be compressed and packed. The tail end discharge port of the air separator 13 is provided with a cyclone separator 14 for separating fine combustible materials.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
