Description

In-situ screening equipment for stored garbage in landfill

Technical Field

The utility model relates to a refuse treatment technical field, in particular to normal position of landfill stock rubbish divides sieve equipment.

Background

Because the harmless treatment technology of domestic garbage is generally carried out in China for a short time, relatively more stock garbage treatment projects such as irregular domestic garbage stacking points, substandard domestic garbage treatment facilities, landfills with saturated storage capacity and the like are formed due to historical reasons and insufficient capacity of the garbage treatment facilities, and thus, the stock regulation market in China is huge at present. At present, most of landfill sites for developing screening work face the dilemma that the landfill sites are close to full capacity and domestic garbage can not go, so that the requirement on the efficiency of screening engineering is high. However, most landfill sites are remote in site selection, and the building area of newly-built screening projects is limited by external factors such as landforms, peripheral railways and the like. In the traditional screening project, potential safety hazards and resources are wasted when fine soil and rejected objects are backfilled to a landfill site, the fine soil and the rejected objects cannot be backfilled to the original landfill site under the influence of the storage capacity of the landfill site, great challenges exist in going out of a road, and how to realize harmlessness, resource utilization, reduction and effective classification of stored garbage of the landfill site is a great problem in the current landfill site remediation work.

SUMMERY OF THE UTILITY MODEL

For at least one among the above-mentioned technical problem of solution, with the effective classification of the stock rubbish of landfill, the utility model provides an in situ of landfill stock rubbish divides sieve equipment, the technical scheme who adopts as follows:

the utility model provides a screening equipment is divided to normal position of landfill stock rubbish includes one-level drum sieve, disc separator, wind-force sorter and second grade drum sieve, the one-level bin outlet that one-level drum sieve was used for discharging oversize thing feed through to wind-force sorter, the one-level discharge gate that one-level drum sieve was used for discharging undersize thing feed through to disc separator, the first discharge gate that disc separator was used for discharging oversize thing feed through to wind-force sorter, wind-force sorter has the export of discharge heavy matter and the export of discharge light matter, the export of discharge light matter passes through the conveyer belt among the wind-force sorter feeds through to second grade drum sieve.

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

Furthermore, the sieve pores of the secondary drum sieve are larger than those of the primary drum sieve.

Further, a conveying belt is arranged at an outlet of the wind power separator for discharging the heavy materials.

Has the advantages that: effectively sieve stock rubbish for four kinds of rubbish such as fine soil, aggregate, rejects and combustible substance through one-level drum sieve, dish-type sorter, wind-force sorter and second grade drum sieve, improve stock rubbish's sorting rate, but 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 normal position of landfill stock rubbish divides sieve equipment divides the process of screening stock rubbish 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, sieving rejected garbage and packing combustible materials.

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

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 sieve pores of the first-stage drum sieve 11 are larger than those of the disc-type separator 12, oversize matters in the first-stage drum sieve 11 are bricks, stones, plastics and the like with the particle size of more than 40mm, and undersize matters are humus with the particle size of less than 40 mm. The undersize material in the disc type separator 12 is fine soil with the grain diameter less than 10mm, and the rest is oversize material.

The wind power separator 13 has an outlet for discharging heavy materials and an outlet for discharging light materials, the outlet for discharging light materials in the wind power separator 13 is communicated to the secondary drum screen 14 through a conveyor belt, the outlet for discharging heavy materials in the wind power separator 13 is provided with a conveyor belt, and the heavy materials discharged by the wind power separator 13 are conveyed to a bone material pool as aggregate through the conveyor belt. The tail end discharge port of the air separator 13 is provided with a cyclone separator 15 for separating fine combustible substances.

The screen holes of the second-stage drum screen 14 are larger than the screen holes of the first-stage drum screen 11, undersize materials in the second-stage drum screen 14 are fine plastics and humus soil with the grain size smaller than 60mm, and the undersize materials are used as reject materials and are gathered into a reject pool through a conveying belt. Oversize materials of the secondary drum sieve 14 are combustible materials with the grain diameter larger than 60mm, and are converged into a horizontal binding machine through a conveying belt to be compressed and packaged.

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.
