Description

Sorting equipment for garbage stocks

Technical Field

The utility model relates to a refuse treatment technical field, in particular to stock rubbish divide sieve equipment.

Background

The traditional stock garbage screening system is mainly used for screening the stock garbage into combustible materials, aggregate and fine soil, wherein the combustible materials are sent to an incineration plant for direct incineration power generation, partial non-combustible materials are removed through screening, the combustion efficiency of garbage incineration is improved, more waste materials generated after incineration are reduced, the total quantity of garbage transfer and high incineration cost are greatly reduced, the space occupancy rate of a landfill is reduced, and meanwhile, the better resource utilization rate is achieved. However, the flow direction of fine soil is a difficult problem in the current industry, wherein the fine soil has high content of glass, light combustible substances and the like and is difficult to separate, and the low accurate separation rate of fine soil screening is one of the main reasons influencing the resource utilization of the fine soil.

SUMMERY OF THE UTILITY MODEL

For at least one among the above-mentioned technical problem of solution, improve the fine soil separation rate, the utility model provides a stock rubbish divide sieve equipment, the technical scheme who adopts as follows:

the utility model provides a stock rubbish divide sieve equipment includes one-level drum sieve, disc separator, second grade drum sieve and wind-force sorter, the one-level bin outlet intercommunication that the one-level drum sieve is used for discharging oversize material to wind-force sorter, the one-level discharge gate that the one-level drum sieve is used for discharging undersize material communicates to disc separator, the first discharge gate intercommunication that disc separator is used for discharging oversize material to wind-force sorter, the first discharge gate intercommunication that disc separator is used for discharging undersize material to the second grade drum sieve, 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, the sieve pores of the secondary drum sieve are smaller than the sieve pores 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 four kinds of rubbish such as one-level drum sieve, dish-type sorter, second grade drum sieve and wind-force sorter effectively divide into fine soil, rejects, aggregate and combustible substance with stock rubbish, 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 stock rubbish divides the sieve process as follows: stabilizing the garbage pile, digging and transporting the garbage, crushing large garbage, vibrating to disperse the garbage, sieving fine soil and rejected materials, sieving aggregate, and packing combustible materials.

The screening equipment comprises a primary rotary screen 11, a disc type sorting machine 12, a secondary rotary screen 13 and a wind power sorting machine 14, 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 14.

The first-level rotary screen 11 is used for discharging the first-level discharge port of undersize and communicates to the disc separator 12, and the first discharge port that the disc separator 12 is used for discharging the undersize communicates to the second-level rotary screen 13, and the first discharge port that the disc separator 12 is used for discharging the oversize communicates to the wind separator 14, and the first-level discharge port that the first-level rotary screen 11 is used for discharging the oversize communicates to the wind separator 14.

The screen holes of the first-level rotary screen 11 are larger than those of the disc-type separator 12, the oversize products of the first-level rotary screen 11 are bricks, stones, plastics and the like with the grain diameter larger than 40mm, and the undersize products are fine soil and light combustible materials with the grain diameter smaller than 40 mm. The undersize of the disc classifier 12 is fine earth and fine combustible with a particle size of less than 15mm, and the balance is oversize, such as granular aggregate and lightweight RDF.

The screen hole of the secondary drum screen 13 is smaller than that of the disc-type separator 12, and the undersize of the secondary drum screen 13 is fine soil with the grain diameter of less than 5 mm. The oversize materials are glass with the grain diameter larger than 5mm and light combustible materials, and are discharged as rejected materials and then enter a rejected material pool through a conveying belt.

The wind power sorting machine 14 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 14, the heavy materials as aggregates enter a bone material pool through the conveying belts, and the light materials as combustible materials enter a box body of the horizontal binding machine through the conveying belts to be compressed and packed. The end discharge port of the air separator 14 is provided with a cyclone separator 15 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.
