Description

FIELD OF SORTING ALIEN SUBSTANCE INCLUDED RECLAIMED WASTE AND POLLUTED SOIL

The present invention relates to an apparatus for sorting foreign matter from various wastes or contaminated soils, and more particularly, to secure earth and sand selected by a trommel having a sorting hole, and then to reselect the foreign matter from the soil. The present invention relates to a landfill waste and a foreign matter sorting device contained in contaminated soil.

Many structures, such as bridges, roads, and other buildings, which have been created in the process of urbanization and industrialization, are gradually aging over the years, and in recent years, reconstruction and redevelopment has been actively promoted in many regions to improve the living culture. have. In the process of dismantling, rebuilding and redeveloping old structures, many construction wastes are generated.

If the construction wastes are buried as it is, it is difficult to secure landfills, landfill costs are high, and the environment is seriously affected. Accordingly, various measures have been taken in each country to treat construction waste in two aspects: protection of natural environment and recycling of resources. In Korea, many treatment devices for construction waste have been developed.

The types of wastes generated at construction sites include construction wastes such as soil, waste concrete, and waste wood, designated wastes such as waste oil and waste paint, and general wastes at the workplace such as waste appliances.

The construction wastes are again divided into soils, construction wastes including waste concrete, waste asphalt, waste bricks, waste tiles, waste stone, waste and waste blocks, waste woods, waste synthetic resins and rebars. Metals, waste papers, waste glass, sludge waste fibers, incineration residues and the like can be divided into mixed wastes. As such, construction wastes containing various wastes are separated into landfill, incineration, and recycling through treatment.In recent years, construction wastes, which occupy a considerable portion of waste, are aggregated into various structures or aggregates. There is a plan to increase the recycling of waste by recycling for use.

Techniques for producing recycled aggregates during the intermediate treatment of landfill wastes according to the prior art usually consist of crushing-screening (magnetic screening, particle size screening, etc.). Based on the product, it is composed of sediment screening-combustible foreign material screening-iron mass screening-foreign material screening (other garbage, fines, etc.).

Since the present invention relates to foreign matter screening, only screening will be described.

Trommel according to the prior art is made of, for example, a cylindrical having an inlet and an outlet on both sides in the longitudinal direction and formed a plurality of sorting holes on the periphery, foreign matter of the size less than the sorting hole among the waste put into the interior while rotating through the drive means Screening.

The sorting hole may be formed by perforation, or alternatively, may be formed between the sorting rods.

Trommel according to the prior art is only the sorting of foreign matter by the sorting hole, the waste to be screened is extremely viscous because the waste containing the high viscosity, especially high viscosity, such as clay and loess.

In this way, when the screening block is blocked, foreign matter cannot be sorted, so that the blocker of the screening hole is scratched to remove the blockage of the screening hole, a blower for blowing high pressure air, and a hammer striking the trommel. Therefore, Trommel itself can not solve the blockage of the selection holes, there is a problem that takes additional cost to eliminate the blockage.

In addition, the trommel may cause partial wear or partial damage, and in this case, since the entire trommel is expensive to replace, the trommel may be left as it is or a temporary member may be padded with another member.

In order to solve this problem, there is a technology that makes the trommel selection rod swingable, but it has the problem that only partial damaged parts cannot be repaired selectively.

In addition, trommel is only to sort out some foreign matter, for example, conventional trommel is a composition that does not satisfy less than 1% of the organic foreign matter content (volume basis) of the sediment to be screened legal standards (about 30mm screen screen) ), There is a problem that a large amount of foreign matter contained in the earth and sand selected by Trommel.

The present invention is to solve the problems as described above, to secure the earth and sand selected by the trommel having a selection hole, and then to re-select the foreign material from the soil and landfill waste that can supply high-quality soil The purpose is to provide a foreign matter sorting device contained in the soil.

The rod is formed in a smaller shape, and includes a plurality of sorting rods that are inserted into the swing groove of the frame so as to be swingable to form a sorting hole. The foreign matter of the particle size smaller than the selection hole is selected, the frame is a frame body of the rim (rim) form having a first groove open to one side, a second groove corresponding to the first groove of the frame body is formed It is coupled to the frame body, characterized in that consisting of a plurality of covers to form the swing groove by the first and second grooves.

According to the foreign matter sorting device included in the landfill waste and contaminated soil according to the present invention, the foreign matter is first screened by the trommel, and the foreign matter content is reselected from the soil selected in the trommel through the foreign material separator 1 Soil quality of less than% can be secured, thus improving the utility of soil and improving reliability as a facility for recycling waste.

And, the effect of the composition of the trommel and foreign matter separator is as follows.

When the sorting rod rotates, it swings inside the swing groove by its own weight.At this time, the impact is generated and the size of the sorting hole is changed so that foreign matters blocking the sorting hole between the sorting rods are removed from the sorting rod. , Blowers, hammers, etc.) can be used to eliminate clogging of the sorting hole, thereby improving the reliability of the foreign matter sorting device and reducing initial investment and maintenance costs.

In addition, if a plurality of selection rods need to be repaired and replaced, some of the selection rods can be opened to cover the selection rods. can do.

The striking roller 160 is preferably installed rotatably in place to reduce the frictional resistance with the selection rod (110).

The selection rod 110 is pushed into the swing groove 121 by the hit roller 160 when passing through the hit roller 160, the swing groove 121 by its own weight when passed through the hit roller 160 It will fall to the outside of the, and the impact occurs in this process, so the fine powder on the surface can be removed.

The striking roller 160 is not limited to that shown in the drawings and may be changed in number and position in various ways.

The outer circumferential surfaces of the sorting rod 110 and the hitting roller 160 may be prevented from slipping so that slip does not occur when the picking rod 110 passes through the hitting roller 160. The anti-slip treatment may be uneven.

12 and 13, the foreign matter separating unit 200, the conveyor 210 for transporting the soil discharged from the trommel 100, to separate the foreign matter of the soil transported along the conveyor 210 with a suction force. Cyclone 230 to be connected to the chute 220 through the box-type chute 220, the duct 231 to seal the top of the conveyor 210 to remove the foreign matter in the soil transported by the chute 220 by the suction force, It is composed of a mesh conveyor 240 for re-selecting the foreign matter scattered by the cyclone 230 by particle size.

Conveyor 210 is connected to the discharge end of the trommel 100 to transfer the earth and sand discharged from the trommel 100, the soil and foreign matter dispersed widely so that the suction force by the cyclone 230 can act on all the soil and foreign matter In addition, the vibration means 250 is applied to float the foreign matter with a small specific gravity in the air.

As shown in Figure 14, the vibration means 250 is rotated in place by the motor 251, the motor 251 and the upper and lower by the vibration shaft 252, the vibration shaft 252, the vibration projection 252a is formed in the circumference Vibration plate 253, vibrating furnace is installed on the vibration plate 253 and consists of one or more bearing rods 254 in contact with the conveyor (210).

The chute 220 seals the upper portion of the conveyor 210 so that the suction force of the cyclone 230 is not lost to the outside, and the discharge chute 221 for discharging the foreign matter that has not passed through the mesh conveyor 240 to the outside is provided. It is provided.

Cyclone 230 is commonly used, and the duct 231 is disposed inside the mesh conveyor 240 so that the suction port is directed toward the chute 220.

The mesh conveyor 240 has a caterpillar shape and a duct 231 is disposed therein.

As illustrated in FIG. 15, the foreign matter separation unit 200 may be sealed through the cover 260.

The action of the foreign matter sorting device included in the landfill waste and contaminated soil according to the present invention is as follows.

Trommel 100 is rotated through the drive means, at this time, the selection rods 110 are moved within the swing groove 121 by the weight. That is, the selection rod 110 disposed at the 6 o'clock position as shown in FIG. 3 is lowered to the bottom of the swing groove 121, and in this state, the selection rod 110 receives a waste smaller than the interval between the selection rods 110. Foreign matter of particle size is discharged down.

On the other hand, some foreign matter is attached to the selection rods 110 may block the selection holes between the selection rods 110, the selection rod 110 is rotated in such a state that the selection holes are blocked. In this way, when the selection rod 110 moves in the 12 o'clock direction beyond the 9 o'clock direction, the swing groove 121 is inclined, and thus moves to the inside of the swing groove 121. At this time, the selection rod 110 collides with the frame body 122 and foreign matter adhered to the selection rod 110 by this collision energy falls from the selection rod 110, and the selection rod 110 is collected inward. When the size of the sorting hole is small, foreign matters fall off the sorting rod (110). When the selection rod 110 collides with the frame body 122 or the cover 123, the shock absorber may absorb shock through the buffers 124 and 125 to reduce wear and noise.

In addition, the selection rod 110 during the rotation of the trommel 100 passes through the hitting roller 160, the picking rod 110 is only because the position can not be changed only the rotation in place the selection rod 110 The hitting roller 160 is pushed into the swinging groove 121, and when passing through the hitting roller 160, it falls to the outside of the swinging groove 121 by its own weight. At this time, the collision of the selection rod 110 and the size change of the selection hole is generated to drop foreign substances attached to the selection rod 110.

As such, some sorting rods 110 of the plurality of sorting rods 110 may be damaged due to the collision of the waste while sorting the foreign matter. In order to repair or replace the selection bar 110 of the damage, the cover 123 is separated, and then the separation bar 110 is separated from the frame body 122, which has been described in detail in the configuration, and thus a detailed description thereof will be omitted.

Soil is discharged from the trommel 100 through the above process, in which case, not only pure earth is contained, but also foreign matters such as fine powder, dust, styrofoam or vinyl, and only the earth and sand are selected through the foreign matter separating unit 200.

Soil and foreign matter selected from the trommel 100 is transferred through the conveyor 210, at which time, the soil and foreign matter transported along the conveyor 210 through the vibration means 250 vibrates to widen on the conveyor 210. Dispersed and foreign matters having a small specific gravity float on the conveyor 210.

The suction force of the cyclone 230 is applied to the inside of the chute 210, and foreign matter except for earth and sand is introduced into the duct 231 by the suction force.

At this time, by the mesh conveyor 240 at the suction port of the duct 231 fine powder or dust having a smaller particle size than the hole of the mesh conveyor 240 is sucked into the duct 231 and collected in the cyclone 230, the mesh conveyor Foreign matter larger than the hole of 240 is moved along the mesh conveyor 240. The foreign matter larger than the hole of the mesh conveyor 240 is attached to the mesh conveyor 240 until it escapes from the duct 231, but when the duct 231 is out of the duct 231, there is no suction force so that the outside of the chute 220 through the discharge chute 221. Is discharged.

Therefore, when the earth and sand pass through the chute 220, various foreign matters are separated, and also, foreign matters are also separated by particle size to secure high quality earth and sand, and foreign matters can be treated by particle size.
