Description

Construction Waste Sorting Equipment {APPARATUS FOR SORTING WASTE IN CONSTRUCTION WASTE}

The present invention relates to a construction waste sorting apparatus, and more particularly, to a construction waste sorting apparatus capable of efficiently sorting wastes by responding favorably according to the type and condition of the wastes.

Types of waste that are inseparable due to working conditions at construction sites such as waste cones, waste ascons, waste wood, rebars, earth and sand, and redevelopment sites, ie construction wastes, vinyl, and household waste It is reaching 40 million tons. In order to recycle these wastes, the wastewater must be sorted by pretreatment, but more than 90% of the wastes are filled. Recycling performance in high value-added areas that are only used for landfilling is very poor.

Recently, technology for screening construction waste has been proposed in recognition of the seriousness of resource recycling and environmental pollution.

However, the conventional construction waste sorting device has a big disadvantage of sorting by the same method as the same system, although there will be a qualitative difference by type of waste.

For example, a method for sorting construction waste according to the prior art is as follows. When mixed waste is put into a hopper, the waste is conveyed to a inlet of a trommel (hereinafter referred to as a sorting bin) having a hole by a belt conveyor. Soil, hard aggregate, etc., which are put into the barrel and passed through the sorting bin, are transferred to a conveying device disposed below the sorting bin, and sorted by another method, and combustible waste, wood, and large Agglomerated waste cone particles are conveyed by the belt conveyor installed at the discharge port of the sorting tube, and the material having a small specific gravity is scattered by the wind power of the blower installed at the drop position of the belt conveyor end, and the material having a large specific gravity is a natural drop or a belt conveyor. Transferred and landfilled.

However, waste cone, waste ascon, iron lumps, combustible wastes (waste vinyl, wood, household waste, earth and sand, etc.) are mixed in the waste generated at the construction site or the waste generated when excavating the landfill waste for the construction of residential land in the landfill. And all the wastes contain a large amount of moisture due to dirt and the like. However, the conventional sorting device does not take into account the moisture contained in the waste during the sorting of the waste, the waste containing the water to block the holes of the sorting container, and this is because the sorting is not made because the sorting efficiency falls, high energy There is a problem that is consumed.

Therefore, it is widely used as a solution to install the impact device using the metal butch tool, but this causes a secondary problem due to noise amplification, there is a problem that causes the breakage of the network, and rotates to another method This material clogging in the screen of the sorting box is burned by burning the flames of the burner and burned to remove the vinyl attached to the screen, and the high pressure air is blown to separate the sorting screen, but the burner temperature is over 1000 ℃. Therefore, it has a problem of emitting fatal secondary pollution due to direct incineration due to overheating.

In addition, the waste containing the wet has a problem of oxidizing the sorting box made of a metallic material, and the aggregate of light and heavy weight directly into the sorting box to cause amplification of noise and breakage of the sorting box when the sorting box is rotated.

And, the aggregate selected as the discharge port in the sorting barrel is sorted into a material with a small specific gravity and a large specific gravity by the blower installed at the end of the belt conveyor, but the waste containing the wet forms a thick layer at the end of the belt conveyor, When the belt conveyor falls, high-concentration materials such as waste cones and combustible materials such as paper, fabric, and vinyl may cause curtains to deteriorate the screening efficiency of combustible wastes, and the selected combustible materials are adsorbed on many soils. Incinerated in landfill.

This secondaryly increased the transportation cost, and caused a large problem in the consumption of a lot of heat energy during incineration and the increase in the treatment cost for the residue after incineration.

The present invention has been made to solve the above problems, and according to the type and characteristics of the waste, the building waste sorting device to efficiently sort the waste and prevent damage to the equipment caused by the waste The purpose is to provide.

Features and advantages of the present invention is based on the accompanying drawings It will be more apparent from the following detailed description. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention based on the principle that the inventor can appropriately define the concept of the term in order to best explain his or her design. The construction waste sorting apparatus according to the present invention, as shown in FIG. 1, is largely divided into primary sorting means 10 and primary sorting means 10 for sorting aggregate from waste. The sorting container 20, which is a secondary screening means for sorting the soil from the waste selected by the) and the waste sorted by the sorting container 20 to finally sort the waste into combustible waste, waste concrete, waste ascon It comprises a tertiary sorting means (30). The sorting bin for sorting waste, the primary sorting means for sorting the waste first before the waste is put into the sorting bin, combustible waste containing a lot of wet (waste vinyl, raw Guide means for sorting the waste, gravel, lightweight aggregate, etc.), and includes a dry waste, which does not include water as a primary screening method that can be selected in the screening method.

As shown in FIG. 1, the primary sorting means 10 may select aggregate from waste mixed with various wastes and remove moisture contained in the waste, and a hopper having an inlet 11a into which waste is injected. (11), a waste input guide plate (12) for sorting waste introduced through the inlet (11a) of the hopper 11, and disposed below the waste input guide plate 12 to sort through the waste input guide plate (12) The weight of the waste which is not sorted by the waste input guide plate 1 is disposed inclined downwardly toward the collector 13 between the collector 13 and the hopper 11 and the sorting tube 20 where the aggregate is collected. A belt conveyor 14 for guiding a large condensate of large condensate is collected in the collector 1. The waste input guide plate 12 is mounted at an inclined end portion downwardly under the inlet 11a of the hopper 11. Airtight May be made of (12a) and sealing plate (12a) around the lower, U-shaped fan, a screen (12b) of the waste such as screening pyekon the weight of each size to be put through to the same angle is inclined to the. In addition, the screen opening and closing plate 12c for closing the upper portion of the screen 12b may be slidably installed on the sealing plate 12a. As described above, the primary screening means 10 contains a lot of waste, especially wet. As a means for removing moisture from the combustible wastes, ie, waste vinyl, household garbage, earth and sand, lightweight aggregate, etc., it is installed below the waste input guide plate 12 to dry the waste introduced by supplying hot air through the blower pipe 15a. In addition, the hot air blower 15 is blown to the sorting tube 20 side and guided to guide the inlet to be introduced into the sorting tube 20 and scattered soil and lightweight aggregate installed at the upper portion of the inlet side of the sorting tube 20. The high temperature hot air generated by the hot air blower 15 dries the wet waste that is sorted or transferred by the screen 12b through the blower tube 15a, and at the same time, the scrub formed into equal portions. High temperature hot air passing between the lean (12b) guides the earth and light aggregates scattered in contact with the waste to the guide plate 16, the guide plate 16 to allow the combustible waste to enter the sorting bin (20). The primary selection means 10 may vary the sorting operation according to the state of the waste, that is, the water content. If the water content is included, the hot air blower 15 is opened by opening the screen 12b as described above. In the case of dry wastes that do not contain moisture, the screen opening and closing plate 12c disposed on the sealing plate 12a in a stack is slid downward to close the U-shaped but chatsal screen 12b. The operation of the hot air fan 15 is stopped, and only the belt conveyor 14 using gravity is operated. Accordingly, the dry waste introduced into the hopper 11 is dropped to the belt conveyor 14 at the transfer end points of the sealed plate 12a and the screen opening and closing plate 12c, and the light and heavy waste aggregate is collected by the collector 13. ) Is separated into an intermediate treatment facility, and the scattered soil or some lightweight aggregate enters the sorting bin 20. As the second sorting means, the sorting bin 20 has a substantially rectangular frame (as shown in FIG. 2). 21, a plurality of rods 22 and 23 having a diameter of approximately 16 mm and mounted in a lattice form may be formed by bending in a circle. And, as shown in Figures 1 and 3, the opening to open and close the sorting cylinder 20 while rotating through the hinge 24a or the like in the sorting cylinder 20 so that the inside of the sorting cylinder 20 can be confirmed. On the other hand, the sorting cylinder 20 is installed so that the angle can be adjusted so that the sorting by the sorting cylinder 20 can be performed smoothly, for example, as shown in FIG. 1 and FIG. The leg 25 of the 20 is a multi-stage angle adjustment hole (15a) is drilled at regular intervals, the outer side of the leg (25) is selectively coupled to the angle adjustment hole (25a) to adjust the inclination of the sorting tube (20) The angle adjusting piece 26 can be assembled, and the sorting tube 20 can be installed at various angles by assembling the angle adjusting piece 26 to any one of the multi-stage angle adjusting holes 25a. As another embodiment of (10), as shown in Fig. 5, the soil, waste cone of the waste carried into the sorting bin (20) When this mainstream is achieved, the second sorting cylinder 20A having 150 mesh can be attached, and a fastening hole 27 is drilled in the outer peripheral surface of the front end of the sorting cylinder 20 and fastened to the second sorting cylinder 20A. A fastening hole 27A communicating with the ball 27 may be provided and detachable through the fastener 28. On the other hand, the waste sorted by the primary sorting means 10 and carried into the sorting container 20 is dry. And the waste containing water, and the sorting bin is rotated through the rotating means to efficiently sort such waste, and the high-pressure exhaust device so that the waste is not stuck to the holes of the sorting bin 20 40. The sorting tube rotating means is, for example, as shown in FIG. 3, for example, a motor 50 for rotating the sorting cylinder 20, and a sprocket 51 formed on the outer peripheral surface of the front end of the sorting cylinder 20. As shown in FIG. And a chain 52 connected to the motor 50 and rotating the sorting tube 20 by the rotational force of the motor 50. The motor 50 sets the drive speed by freely selecting the high speed and the low speed. Here, the motor 50 is converted to a low speed in consideration of waste containing moisture, and is operated at high speed because it operates using a variable transmission (not shown). The low speed can be adjusted freely, and another feature is that the power supply is cut off during the operation of the sorting canister 20, or in the event of a human accident can be subjected to an overload when operating again in an excessive amount of input in the sorting canister 20. On the other hand, the chain 52 coupled to the sprocket 51 formed on the outer peripheral surface of the front end of the sorting tube 20 is relaxed and the chain 52 is loose, so that power transmission can be transmitted to compensate for this, FIGS. 3 and 6. As in the above, the chain tension piece 54 is installed on the frame 53, and the chain 52 is placed on the chain tension piece 54. The high pressure exhaust pipe 40 supplies compressed air, that is, pressure energy. With speed energy By switching and injecting at high speed and simultaneously injecting hot air, as shown in FIG. 7, high-pressure air is supplied and sprayed, and as shown in FIG. 4, an upper portion of the sorting cylinder 20 is located above the sorting cylinder 20. In the longitudinal direction, a plurality of them are arranged at regular intervals. When water-containing waste flows into the sorting vessel 20, the motor 50, which is a power source, is driven at a low speed, and the high pressure exhaust pipe 40 is operated with hot air and high speed. As the air is injected, the left and right reciprocating motion is performed, and the waste which tries to contact the sorting container 20 by moisture is dried and moved to the outlet of the sorting container 20 without being touched. (20) may sort the soil out of the waste, for this purpose, as shown in Figure 1, the lower portion of the sorting canister 20, the belt for transferring the soil passed through the sorting canister 20 to a designated place Conveyor 29 is installed The. The belt conveyor 29 conveys the earth and sand discharged from the inside of the sorting container 20 to an appropriate position of the yard. The third sorting means 30 includes combustible waste and some light weight not sorted in the sorting container 20. As a means for processing the aggregate of the, as shown in Figure 4, the duct 31 communicated to the outlet end of the sorting cylinder 20, and disposed below the outlet end of the sorting cylinder 20, Blower 32 for flying the falling flammable waste into the duct 31 and the combustible waste is scattered by the wind power of the blower 32 is installed at the outlet end of the sorting cylinder 20, the duct 31 It is composed of a scattering curtain 33 for guiding to, and the combustible waste is sorted by the wind power of the blower 32 among the waste introduced into the sorting container 20 to the duct 31 to be collected in a yard site. Lightweight aggregate which falls without being scattered by wind power of blower 32 A belt conveyor 34 is further installed at the lower portion of the inlet side of the duct 31 for transport. In addition, an electromagnet 35 capable of separating the iron contained in the aggregate in the process of moving the introduced aggregate to the belt conveyor 34 is disposed, and the aggregate in which the iron is separated by the electromagnet 35 is a belt conveyor 34. The yard is gathered at a regular place.

It describes the operation of the construction waste sorting apparatus according to the present invention configured as described above.

Before inputting the waste, the angle of the sorting container 20 is set to an optimal angle for sorting the building, and in this way, the angle adjusting piece 26 is optimally adjusted for the angle of the sorting container 20. Tighten to 25a. On the other hand, when the waste, such as soil, waste cones, etc. make up the mainstream, as shown in Figure 5, connecting the sorting barrel 20A of 150 mesh to the sorting cylinder 20. As a connecting method of the sorting cylinder 20A, the fastener 28 is fastened and connected in the state which matched the fastening holes 27 and 27A of the 1st sorting cylinder 20 and the 2nd sorting cylinder 20A. In this way, after the preparatory work for sorting the waste is completed, the waste is introduced through the inlet 11a. When light and heavy waste are put into the hopper 11 of the primary sorting means 10, the waste is introduced into the waste input plate. Of the 12, it is dropped to the sealing plate 12a, wherein the sealing plate 12a is a wear-resistant reinforcing plate is characterized in that the damage or deformation does not occur even if the waste having a large specific gravity falls.

Wastes input to the primary sorting means 10 may be classified into dry and moisture-containing wastes. When the wastes contain much moisture, the screen 12b is opened by the screen opening and closing plate 12c. The hot air fan 15 is operated to remove moisture from the waste by the following method. The waste dropped to the sealing plate 12a is moved to the next U-shaped but chatsal screen 12b, which is placed on the screen 12b. The waste passed between each constituted fraction is dropped into the collector 13 disposed thereunder. At this time, the fine earth and sand are scattered by the wind exhausted from the blower tube 15a of the hot air blower 15 and transferred to the induction plate 16, and a part of the waste containing moisture by the high temperature hot air is dried for a predetermined time. In the case of dry waste, the screen opening and closing plate 12c is slid to close the screen 12b and the driving of the hot air fan 15 is stopped. Let's do it.

On the other hand, the waste of a large specific gravity sorted by the screen 12b falls to the lower end of the belt conveyor 14, and is collected by the collector 13 by gravity.

Subsequent treatment of the aggregate collected in the collector 13 of the primary sorting means 10 is, for example, primary crushing process → primary electromagnet scrap separation process → earth and sand separation process → flammable waste sorting masonry → raw material-foreign material separation → raw stone -Good quality recycled aggregate is produced by washing → secondary crushing process → secondary electromagnet iron separation process → three-stage screen net process, and more than 25mm is transferred to the third electromagnet iron strip separation process disposed at the upper part of the transfer device. Aggregate not screened in the three-stage screen net process is recycled back to the cone or impact crusher, but at this time, the final device is separated through the 4th electromagnet iron piece separation fixation and the iron piece is separated and crushed. It can be reproduced by a process that can be reproduced by the three-stage screen network.

Meanwhile, the waste sorted by the primary sorting means 10 and brought into the sorting container 20 may be classified into dry and moisture-containing waste.

First, in the case of treating waste containing moisture, in order to increase the efficiency of the sorting operation by drying the waste carried in the sorting tank 20 within a sufficient time, if the motor 50 having a variable transmission is driven at a low speed, the motor ( 50, the chain 52 built in the shaft rotates to rotate the sorting tube 20 at a low speed. On the other hand, the chain 52 is tensioned by the chain tension piece 54 can transmit the power of the motor 50 to the sorting tube (20).

In addition, in the upper upper side of the sorting vessel 20, the high-pressure exhaust pipe 40 sprays hot air having a high temperature of heat at a high speed and at the same time reciprocates the waste to try to contact the sorting vessel 20 with the sorting vessel 20. It does not touch and is to move to the outlet of the sorting tube (20). At this time, the earth and sand that passed through the screen of the sorting container 20 is dropped to the belt Kenveyer 29 disposed in the lower part of the sorting container 20, the belt conveyor 29 so that the dropped soil is collected in a proper position of the yard. do.

Soil and the like are sorted by the sorting container 20 and the high-pressure exhaust pipe 40, which are the secondary sorting means, are then sorted into wastes such as flammable waste and other aggregates by the third sorting means 30, which is the process. Combustible waste and some lightweight aggregates that are not sorted in the sorting canister 20 and processed at the end of the sorting canister 20 are caused by the wind power of the blower 32 disposed at the end of the sorting canister 20. The waste introduced into the duct 31, the waste introduced into the duct 31 is collected at a certain place in the yard along the duct 31, and drops from the end of the sorting tube 20 without being scattered by the wind power of the blower 32. Light weight aggregate is dropped to the belt conveyor 34 disposed in the lower portion of the duct 31, the aggregate is transported along the belt conveyor 34, in this process the iron contained in the aggregate by the electromagnet 35 Is separated.

As described above, according to the construction waste sorting apparatus according to the present invention, it is possible to efficiently sort various wastes by setting the wastes to be appropriately sorted according to the type and state of the wastes. It is possible to promote the recycling of the waste resources by sorting by type through the -2-3rd sorting process. The present invention has been described and illustrated with reference to a preferred embodiment for illustrating the principles of the present invention. However, the present invention is not limited to the configuration and operation as shown and described as such. Rather, it will be apparent to those skilled in the art that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims.
