The present invention relates to a sediment sorting apparatus that can effectively filter out foreign substances contained in the sediment and sediment during the process of sorting the soil and waste by crushing / crushing the waste concrete of the unsanitary landfill or construction and construction waste, In particular, it is a conveyor equipped with a rotary device for crushing / crushing lumped soil, T / C conveyor equipped with rod comb on the outer circumference of the conveyor rubber belt, and a vibration sieve provided under the T / C conveyor discharge part. Consists of a transport conveyor for transporting and loading the final sorted soil and foreign matters sequentially, crushed agglomerated soil or foreign matter in the selected soil through a sorting device such as trommel or vibrating sieve first, and included in the crushed soil Foreign matter (flammable garbage such as wood, vinyl, leather, textiles, plastics, etc.) The present invention relates to a soil sediment sorting device using a true comb-conveyor, which is filtered through a continuous process so that the soil and foreign matter can be sorted / separated reliably.

In general, construction wastes on construction sites or trash already buried in landfills are randomly reclaimed without proper selection of recyclable resources and wastes that do not decompose over a long period of time, causing serious soil contamination and recycling of resources. Raises the problem of being very inefficient.

To solve this problem, it is inevitable to excavate random landfilled waste or construction waste that is disposed of at construction sites, and to sort out the soil and recyclable resources and combustible waste contained in the landfill.

To this end, a sorting device that separates / selects soil and recyclable resources contained in embedded construction waste or trash is proposed and applied in various forms through domestic and foreign patents and utility models.

Commonly known sorting devices include a conveyor for transferring inputted construction waste or trash, a crusher for crushing / crushing the pulverized material introduced through the conveyor, and a crusher crushed / crushed to a certain granularity through the crusher. Vibration sorter for sorting foreign matter and soil, and cylindrical screen (referred to as "screening net") or flat screen to filter out and recycle only the soil from the pulverized products produced through the vibrating sorter. Consists of the included configuration.

However, in the prior art of the above configuration, the screen has a variety of sizes of 35mm ~ 50mm of the scale of the screen, when screening sediment using a screening sieve or vibrating sieve screen screen is too small if the screen mesh is too small The clogging of soils having a relatively uniform particle size is not possible, and the sorting efficiency of the soils is low. When the mesh is relatively large, it is very difficult to select high-quality soils because of the high content of foreign matter in the soil.

In order to solve this problem, sediment and sediment are separated into water aeration method using wind and water specific gravity difference or wind gravity method and withdrawal rake method, but underwater aeration method uses water pollution and sludge generation. Many problems have been pointed out, and with the extractor rake method, the extractor rake is installed at a 90˚ angle on the semi-circular conveyor through which the soil and the foreign matter are transported so that the foreign matter contained in the soil can be removed by the rotation operation of the extractor. Although it is known as a sorting device, this sorting device is configured to pull out foreign matter in the soil moving on a semi-circular conveying conveyor by the rotational movement of the extracting rake. If foreign matter adheres between them, the screening rate will be lowered. Unreasonable problems have been pointed out, and the earth or sand located in the bottom or corner blind area that the rake does not come in contact with the problem that the removal of foreign matter is not at all. In particular, the extraction rake has not only the decisive problem of incorporation of soil due to the attachment of the brush and the foreign matter, but also the decisive problem of not being able to pull the foreign matter inside the wet soil. There are many problems. In addition, the wind power method uses a strong blower, which is difficult to separate the foreign matters contained in the soil due to mutual interference due to the mixing of the soil and the foreign matters. Unlike the wind weighting method, there is a problem of scattering and dust generation.

The present invention has been made in view of the problems of the prior art as described above, to improve the sorting efficiency by primarily crushing / crushing the lumped soil and foreign matter of the soil selected through the waste / soil sorting device, included in the soil The foreign matter (combustible waste such as wood, vinyl, leather, fiber, plastic, etc.) passes through 100% of the upwardly rotating T / C conveyor with a comb teeth to filter the foreign matter, while the iron contained in the foreign material is conveyed. Separating and discharging by the magnetic drum installed on it improves the efficiency of sorting out foreign substances, and light combustible wastes such as styrofoam granules and vinyl chips pass through the wind gravity separator to reliably separate / select the foreign substances contained in the soil and the soil. Provides soil sediment sorting device using true comb conveyor to obtain only soil sediment Its purpose is to.

As a technical means for achieving the above object, the present invention is a conveyor for transporting the input of construction, construction waste or unsanitary landfill waste, crusher for crushing / crushing the selected object introduced through the conveyor, and the crusher All sorting devices including a vibrating sorter that separates foreign matter and soil contained in waste and crushed waste and crushed to a certain granularity, or sorting net that filters foreign matter out of soil and only the soil having a certain particle size. In the present invention, the primary conveyor having a rotary crusher for crushing / pulverizing the sorted sediment separated and discharged through the sorting device, and the foreign matter contained in the sorted sediment discharged through the primary conveyor again to filter the conveyor again Teeth of a Comb (T / C) is formed on the outer periphery of the belt at regular intervals.

It is relatively heavy and plays a role in separating / selecting incombustible soils, etc., which are not affected by the blowing force of water.

The operation and effect of the present invention having such a configuration will be described with reference to the accompanying drawings, FIGS. 1 to 3.

When the selected sorted matter is introduced through the hopper 12 of the primary conveyor 10 through the existing earth and sand sorting device, the injected sorted matter is loaded on the primary conveyor 10 and transferred. The agglomerated soil during the process of conveying through the conveyor 10 is crushed / crushed while passing through the rotary crusher 14 to have a constant particle size.

Here, the rotary crusher 14 not only serves to crush / crush the foreign matter and the soil and the lump of soil over a predetermined standard as above, but also exposes the foreign matter buried in the lump and exposes the light foreign matter pressed in the soil to the top of the soil. It also works to let.

Subsequently, the object to be subjected to the crushing / crushing process as described above is transferred to the discharge side of the other side of the primary conveyor 10 and then introduced into the primary T / C conveyor 20, and the primary T / C conveyor ( 20) The sediment to be injected into the side is filtered by the action of the comb bar rod 26 by the upward rotation of the T / C conveyor (20), and the filtered soil and foreign substances are respectively the primary conveyor (10) and 1 The secondary T / C conveyor 20 is loaded on the secondary conveyors 40a and 40b located below the adjacent soil dropping point and below the outlet point of the primary T / C conveyor 20 and is the next process, the secondary T / C conveyor. 50a, 50b is transferred.

As described above, the object to be transported to the secondary T / C conveyors 50a and 50b is once again subjected to the picking of the comb bar 56 by the upward rotation of the secondary T / C conveyors 50a and 50b. The foreign material is filtered out.

Herein, the operation of the T / C conveyors 20 and 50 will be described in detail. On the conveyor belts 22 and 52 of the T / C conveyors 20 and 50, the steel bar comb 26 is disposed at equal intervals. Since the 56 is installed, the selected object dropped to the T / C conveyor 20 and 50 via the primary conveyor 10 is rotated upward by the falling weight of the T / C conveyor 20 ( 100% of the comb bar (26) and (56) of the comb bar hit 100%, and in the process, combustible materials such as clay, vinyl, wood, leather, fibers, and plastics, which are relatively granular, are filtered and filtered. Take the T / C conveyor (20, 50) to the other side, and the secondary conveyor (40b) and tertiary conveyor (60b) located below the outlet side of the primary and secondary T / C conveyor (20, 50), respectively. The sedimentary sediment loaded on the upper surface and attached to the combustible material having a relatively small particle size passes through the comb bar 26 and 56 and another two pieces below it. By being loaded on the primary conveyor 40a and the tertiary conveyor 60a, it is possible to separate and separate relatively small-sized soil and large-sized foreign matter.

At this time, the permanent magnets (not shown) are installed in the drums 28 and 58 adjacent to the primary to secondary conveyors 10 and 40 among the drums for driving the T / C conveyors 20 and 50. Along with the foreign matter to be filtered, heavy foreign substances such as steel can be filtered together. In addition, as shown in Figs. 2 to 3, the convex material 54 is installed at the soil dropping point adjacent to the discharge points of the secondary conveyors 40a and 40b and the secondary T / C conveyors 50a and 50b. Light-weight foreign bodies such as and styrofoam are filtered out by the fan's blowing force.

Subsequently, the final sedimentary soil having a relatively small particle size passing through the comb bar among the sediments subjected to the T / C conveyor's sifting operation as described above is located below the inlet side of the secondary T / C conveyors 50a and 50b. The third conveyor (60a) is transported to the soil discharge conveyor (80), the foreign matter filtered by the sewage operation of the secondary T / C conveyor (50a, 50b) and the soil having a relatively large particle size is secondary T / C It is loaded on the conveyor (50a) (50b) and transferred to the other side to fall to the vibration sieve 70 having a mesh of 15mm ~ 20mm to undergo a re-garching process again.

The sedimentary soil that has passed through the vibration blade 70 through the sieve process of the vibration blade 70 is transported to the soil discharge conveyor 80 by another third conveyor 60b positioned below the vibration blade. The soil and foreign matter having a relatively large particle size finally filtered out from the housing 70 are transferred to the foreign matter discharge conveyor 90 located on the side of the vibration housing 70. That is, the soil discharge conveyor (80) is to carry only the high-quality sorted soil is finally filtered through the T / C conveyor and the sieve of the vibration sieve, and transport it, the foreign matter discharge conveyor (90) is finally filtered Foreign matter is loaded and transported.

Here, the foreign matter discharged on the foreign substance discharge conveyor 90 is moved to a state in which a relatively heavy soil and light combustible waste of a predetermined size or more is mixed, such a soil and combustible waste is rearward of the foreign substance discharge conveyor (90). The wind is selected by separating the wind selector 100 is collected in different places. That is, among the final filtered foreign matters, relatively heavy soils and lightweight flammable foreign materials are separated / selected and discharged from each other by the blowing action by the wind 102 of the wind gravity separator 100, and thus the flammable foreign matters affected by the blowing force. Silver is loaded on the discharge conveyor 104 and transported to the other side is not affected by the soil is dropped by the foreign matter discharge conveyor discharge point by its own weight is to be able to separate / select each other to discharge. Of course, by installing the conveyor 120 further at the discharge point of the wind gravity selector 100 so that the light foreign matter filtered through the wind gravity selector 100 is collected separately, and the earthenware dropped in the downward direction of the wind gravity selector 100 is It is preferable to be separately discharged through the conveyor 110 installed to the other side.

According to the earth and sand foreign matter sorting apparatus according to the present invention that operates as described above, the sorted material is injected into the primary while passing through the primary conveyor (10) is crushed / pulverized to be discharged in an easy state to sort the foreign matter, discharged The sediment to be separated is separated / selected into foreign substances including high quality soil and earth and sand having a uniform particle size through the dusting action and the vibration blade 70 according to the upward rotation of the multi-stage T / C conveyors 20 and 50. As a result, the large amount of mixed soil discharged by mixing with foreign matter is separated / selected while passing through the wind gravity separator 100, thereby reducing the amount of foreign matter and recycling the soil.

As described above, according to the present invention, the soil sediment sorting apparatus using the true comb meat conveyor is a lumped soil among the soil selected through the general garbage / soil sorting apparatus is primarily crushed / crushed through the primary conveyor device, primary and Soil and foreign substances (flammable waste such as wood, vinyl, leather, and textiles) and metal recyclable irons and soils, which were included in the sediment, were separated / selected through the secondary T / C conveyor and vibration By discharging, the sediment and sediment contained in the sediment can be separated and sorted more precisely than the conventional sorting device. Thus, only high quality sediment can be obtained. In the macro aspect, the segregated waste and sewage can be separated and sorted separately. Since only a small amount of garbage can be landfilled, the problems associated with landfill can be effectively solved. There is such an advantage.

In the above, a preferred embodiment of the present invention has been illustrated and described by way of example, but the present invention should not be limited to the above-described embodiment, but the general knowledge according to the technical field to which the present invention belongs without departing from the spirit of the present invention. Various changes and modifications may be made by a person having
