[DESCRIPTION]

[invention Title] METHOD FOR DISPOSAL OF WASTE MATERIAL USING MOVABLE TRAILER EQUIPPED MULTI-ROUND SEPARATOR AND VARIABLE 5. VIBRATING-HOPPER ON THE SPOT AND APPARATUS THEREOF

[Technical Field] The present invention relates, in general, to a method and apparatus for treating waste in-situ using a trailer equipped with a multiple round separator and a0 variable vibrating hopper and, more particularly, to a method and apparatus for treating waste in-situ,. which uses a trailer equipped with a vibrating hopper serving as an input unit and a round separator serving as a separating unit, thus allowing easy movement and installation of5 equipment, and allowing the angles of the vibrating hopper and the round separator mounted on the trailer to be appropriately adjusted depending on the characteristics of the waste, and including a waste separating process using an air line, therefore allowing waste to be rapidly treated0 at the location where the waste is produced.

[Background Art] Generally, waste produced in landfill sites and construction sites, such as redevelopment sites or reconstruction sites, contains various substances, including earth and sand, concrete, unusable wood, asphalt, rocks, plastics, paper and vinyl. In the past, all construction waste was discarded and buried in the ground, regardless of whether the waste is recyclable or not. This wastes resources, and degrades the environment due to the buried waste, so that the conventional waste treatment method is not environmentally friendly. A basic construction of a conventional apparatus using a centrifugal separator (round separator) so as to separate waste is as follows.

Input conveyor— > Centrifugal separator-* Output conveyor— Blower - Lower conveyor ^■ Earth and sand The separating apparatus which separates waste in this way has been produced by about 10 companies around the world. Conventional separating apparatuses which have been produced in Korea are disclosed in Korean Patent Appln. No. 10-1996-0012303, Patent Appln. No. 10-1998-0018930, etc. In order to recycle waste having various characteristics, perfect separation of the waste and removal of impurities are required in-situ. To this end, it is important to adjust the angles of both the vibrating hopper acting as the input unit and the round separator acting as the separating unit, according to the characteristics or kind of waste. However, the conventional input and separating units are constructed so that waste is input into an input conveyor and the angle only of the separating unit is adjusted. Alternatively, the conventional input and separating units are constructed so that the angles of the input and separating units are individually adjusted. Further, the angle adjustment range is restrictive, so that it is difficult to appropriately treat various kinds of waste in-situ. Further, the conventional method and apparatus for recycling waste is problematic in that a hopper or a rotary drum is installed at a position where waste is blown and dropped by a blower, so that the rotary drum may be undesirably stopped by impurities caught in or adhered to the rotary drum, and noise may be excessively generated. Due to such problems, it is difficult to recycle waste. However, in order to recycle waste, it is most important and difficult to remove impurities from the waste. Therefore, a new method and apparatus for treating waste in-situ is required to solve the problems.

Another object of the present invention is to provide a method and apparatus for treating waste in-situ, which includes a blowing system, thus allowing impurities to be smoothly discharged, and preventing noise from being generated, during the treatment of the waste.

[Best Mode] Hereinafter, the construction and operation of the present invention will be described in detail in conjunction with the accompanying drawings. FIG. 1 shows a waste treatment apparatus, according to an embodiment of the present invention. In a brief description, in order to separate impurities from separated small-sized waste, the waste is separated once again using a plane vibrating separator 3. A blower 7 is installed under the plane vibrating separator 3 and separates the small-sized impurities using the suction force of the blower 7. The small-sized impurities are discharged through a line connected to an outlet for discharging medium-sized impurities and an outlet of the blower 7. Thereby, high quality earth and sand are obtained. In a detailed description, the present invention uses a trailer 1 equipped with a multiple round separator and a vibrating hopper 11, thus allowing easy and smooth movement and installation of the equipment, therefore allowing waste to be rapidly treated at the place where the waste is produced. The equipment is deployed and used at the place where waste is produced or a place where buried waste exists . Two or more foldable conveyors are mounted to one side or to left and right sides of a body of the trailer 1. The foldable conveyors are unfolded in-situ to feed separated substances to desired positions. A separation net of the multiple round separator 12 mounted on the trailer 1 is selected from among a rubber net, , a steel perforated net, a mesh net, and others. According to the intended purpose, two or more separation nets having different meshes are installed. When one desires to classify waste into three sizes, a small-mesh separation net is used at an inlet side, and a large-mesh separation net is used at an outlet side. In a detailed description, the movable trailer l having the above-mentioned construction is placed at a desired spot, and then the foldable conveyors are unfolded. A blowing and feeding means is installed at an outlet side of the round separator 12. The blowing and feeding means includes a blower 8, a separation conveyor 2, and an air conveyor 6. The blower 8 is installed under an end of a foldable conveyor 14 provided at the outlet side of the multiple round separator 12, and blows impurities. The separation conveyor 2 is placed under the foldable conveyor 14, and feeds waste which is not blown by the blower but is dropped. , The air conveyor 6 is installed at a position where the blown impurities drop, with windbreaks 61 provided on both sides of an upper portion of the conveyor to define an air path. Further, another blowing and feeding means is provided at an inlet side of the round separator 12. The blowing and feeding means includes the plane vibrating separator 3, the blower 7, a discharge conveyor 5, and a lower conveyor 4. The plane vibrating separator 3 is installed under a foldable conveyor 13 provided at the inlet side of the multiple round separator 12, and separates waste into two or more sizes, thus sorting impurities from the separated small-sized waste again. The blower 7 is installed under an outlet side of the plane vibrating separator 3, and blows and sorts impurities using an air pressure. The discharge conveyor 5 is installed at an end of the outlet of the plane vibrating separator and feeds separated aggregates to a predetermined position. The lower conveyor 4 is installed under an inlet side of the plane vibrating separator 3, and feeds separated earth and sand to a predetermined position. In this way, the construction for treating, waste is completed. Further, a branch line, that is, an air suction line 71 extends from an inlet provided opposite the outlet of the blower 7 to a position between the inlet side of the plane vibrating separator 3 and the lower conveyor 4. Impurities sorted from separated earth and sand are drawn through a suction opening 72, and are discharged through the outlet of the blower 7. When waste is treated using such a construction, a waste separation path is as follows. That is, after medium- sized aggregates (50~100mm) are fed through the foldable conveyor 14 provided at the outlet side of the round separator and the separation conveyor 2, the medium-sized aggregates accumulate at a position around the separation conveyor 2. Meanwhile, large-sized aggregates (100mm or higher) drop from an end of the multiple round separator 12 after passing through the foldable conveyor 14 provided at the outlet side of the multiple round separator 12. Thus, the large-sized aggregates accumulate at a position around the end of the round separator. Aggregates, fed through the foldable conveyor 13 provided at the inlet side of the multiple round separator 12 into the plane vibrating separator 3, are separated into small-sized aggregates (less than 25mm) and medium-sized aggregates (25~50mm) . The small-sized aggregates accumulate at an end of the lower conveyor 4 installed at the inlet side of the plane vibrating separator 3, and the medium- sized aggregates accumulate at an end of the discharge conveyor 5 provided at the outlet side of the plane vibrating separator 3. When the waste is treated using the above-mentioned construction, an impurity separation path is as follows. That is, while the waste is fed through the foldable conveyor 14 provided at the outlet side of the multiple round separator 12, impurities are blown by an air pressure of the blower 8 and dropped onto the air conveyor 6. Thereafter, the impurities are smoothly fed through the air. path of the air conveyor 6 without generating noise, and accumulate at a waste box which is installed at a rear end of the air conveyor. Further, when waste passes through the foldable conveyor 13 provided at the inlet side of the multiple round separator 12, and enters the plane vibrating separator 3, the waste is separated once again. Thereafter, impurities are blown and accumulate at a predetermined position by an air pressure of the blower 7 which is installed at the outlet side of the plane vibrating separator 3. Further, heavy steel, wood, or the like is sorted from the waste, while the waste passes through the separation conveyor. In the drawings, solid lines denote an aggregate feeding line, and dotted lines denote an impurity feeding line. In this case, the impurities are defined as substances other than aggregates, for example, vinyl, rags, wood, twigs, steel, etc.. FIG. 2 shows a waste treatment apparatus, according to another embodiment of the present invention. In a brief description, in order to sort impurities from separated medium-sized waste, a blower 8 is installed under a foldable conveyor 14 provided at an outlet side of a multiple round separator 12, thus separating waste dropping from the foldable conveyor 14 using the air pressure of the blower. An air conveyor 6 is installed at a position where the waste is dropped, thus allowing impurities to be smoothly discharged. Further, a suction opening is provided at an end of a foldable conveyor 13 which is provided at an inlet side of the multiple round separator 12, and is connected to an outlet side of the blower 8, thus drawing and sorting small-sized impurities. That is, the general construction of FIG. 2 remains the same as FIG. 1 except that only the foldable conveyor 13 is installed at the inlet side of the multiple round separator 12. Unlike the construction of FIG. 1, a branch line, that is, /an air suction line 81, extends from an inlet which is opposite an outlet of the blower 8 installed at the outlet side of the multiple round separator 12, to a position above the foldable conveyor 13 which is provided at the inlet side of the round separator 12. Through the suction opening 82 provided at an end of the air suction line, impurities are drawn. When waste is treated using such a construction, an aggregate separation path is as follows. That is, medium- sized aggregates (40-lOOmm) are fed through the foldable conveyor 14 provided at the outlet side of the multiple round separator 12, and accumulate at a position around the separation conveyor 2. Meanwhile, large-sized aggregates (100mm or higher) drop from an end of the multiple round separator 12 after passing through the foldable conveyor 14 provided at the outlet side of the multiple round separator 12, and accumulate at a position around the end of the multiple round separator 12. Further, small-sized aggregates (less than 40mm) accumulate at an end of the foldable conveyor 13 which is provided at the inlet side of the multiple round separator 12. Meanwhile, when the waste is treated using such a construction, an impurity separation path is as follows.^' While impurities are fed through the foldable conveyor 14 provided at the outlet side of the multiple round separator 12, the impurities are blown by the air pressure of the blower 8 and dropped onto the air conveyor 6. Afterwards, the impurities smoothly pass through the air path of the air conveyor 6 without generating noise, and accumulate at a waste box that is installed at a rear end of the air conveyor. Further, heavy steel material, wood, and the like are sorted from the waste while the waste passes through the separation conveyor. FIG. 3 shows a waste treatment apparatus, according to a further embodiment of the present invention. In order to efficiently separate wet waste, such as waste produced at a landfill site, a multiple round separator 12 mounted on a trailer 1 is configured as shown in the drawing. That is, a large-mesh separation net is provided at an inlet side of a multiple round separator, and a small-mesh separation net is provided at an outlet side of the multiple round separator. In a brief description, when it is required to treat waste having high moisture content, a variable vibrating hopper and the multiple round separator 12, which is constructed so that the large-mesh separation net is provided at the inlet side thereof and the small- mesh separation net is provided at the outlet side thereof, are mounted on the trailer 1. Foldable conveyors 13 and 14, provided on the trailer 1 to feed waste of different sizes, are unfolded on one side of the trailer 1. Further, a discharge conveyor 5 is installed at an end of the separation net. A blower 9 is installed under the discharge conveyor 5 to blow and sort impurities using an air pressure. Further, branch lines, namely, air suction lines 91a and 91b, extend from an inlet opposite an outlet of the blower 9 and are connected to upper portions around ends of the foldable conveyors 13 and 14, respectively. Impurities are drawn through suction openings 92a and 92b provided at ends of the air suction lines. Aggregates which are not blown but are dropped are fed through the separation conveyor 2. Further, an air conveyor 6 having an air path is installed at a position where blown impurities drop. Through the air path, impurities are smoothly fed to a predetermined position by the air pressure of the blower 8. When waste is treated using such a construction, an aggregate separation path is as follows. Aggregates having sizes of 40mm or less are fed through the foldable conveyor 13 provided at the inlet side of the round separator, and accumulate at a position around the foldable conveyor 13. Further, aggregates having sizes of 40mm or less are fed through the foldable conveyor 14 provided at the outlet side of the multiple round separator, and accumulate at a position around the foldable conveyor 14. Meanwhile, aggregates having sizes of 40mm or more drop from the discharge conveyor 5 provided at an end of the multiple round separator 1. The aggregates are fed- through the separation conveyor 2, and accumulate at a position around the separation conveyor 2. Meanwhile, when the waste is treated using such a construction, an impurity separation path is as follows. While impurities pass through the discharge conveyor 5 provided at the end of the multiple round separator 12, the impurities are blown by the air pressure of the blower 9 and are dropped onto the air conveyor 6. Thereafter, the impurities are smoothly fed through the air path of the airconveyor 6 without generating noise, and accumulate in a waste box which is installed at a rear end^' of , the air conveyor. Further, heavy steel material, wood, and the like are sorted from the waste while the waste passing through the separation conveyor. The constructions of FIGS. 1 to 3 may be used independently or together, according to the conditions of the spot where the waste is treated. FIGS. 4a to 4d show examples of various angle adjustments of the round separator 12 and the input unit that are mounted on the trailer 1 of this invention. By adjusting the angle of the trailer 1 equipped with the multiple round separator and the vibrating, hopper 11, it is possible to simultaneously adjust the angles of both the input unit and the separation unit. An angle adjustment range is increased, so that it is possible to efficiently separate various kinds of waste. Generally, in the case of light waste, the trailer is adjusted to have a large angle (8^° or higher) . Conversely, in the case of heavy waste, the trailer is adjusted to have a small angle (1° ~ less than 8° ) . In this way, various kinds of waste can be efficiently separated. A central point between two wheels serving as a drive means 15 of the trailer 1, provided at a side of the round separator 12, is established as the reference point of an inclination. Thus, the inclination is measured as an angle between the reference point and the body frame of the trailer 1. In a detailed description, FIG. 4a shows the angle when the trailer 1 moves. Referring to the drawing, the inclination of the body frame is 0^° , so that the inclination of the multiple round separator 12 determined by the inclination of the frame is 0° . Further, the inclination of the variable vibrating hopper 1 is 2^° . FIG. 4b shows angles when light waste produced at a new construction site is treated. The inclination of the body frame is 6^° (it is possible to adjust the inclination up to 20° or higher) , so that the inclination of the multiple round separator 12 determined by the inclination of the frame is 6^° . Further, the inclination of the variable vibrating hopper 11 is 4° . FIG. 4c shows angles when waste produced at a redevelopment site is treated. Referring to the drawing, the inclination of the body frame is 6° (it is possible to adjust the inclination up to 20° or higher) , so that the inclination of the multiple round separator 12 determined by the inclination of the frame is 6^° . Further, the inclination of the variable vibrating hopper 11 is 6^° . FIG. 4d shows angles when waste produced at a landfill site is treated. Referring to the drawing, the inclination of the body frame is 6° (it is possible to adjust the inclination up to 20^° or higher) , so that the inclination of the multiple round separator 12 determined by the inclination of the frame is 6^° . Further, the inclination of the variable vibrating hopper 11 is 10^° . The angles stated hereinbefore provide the best, results depending on site conditions. FIG. 5 shows examples of detailed angle adjustment of the input unit of FIG. 4. The variable vibrating hopper 11 includes a hopper angle adjusting unit, a spring 113, a screw-type adjusting unit 117, and a spring support unit. The angle adjusting unit includes a hopper angle adjusting plate 111 and a stop unit 112. A plurality of holes is provided on the angle adjusting plate 111 at predetermined angles. When the angle adjusting plate 111 is moved up or down by a hydraulic, pneumatic or ^' mechanical device and adjusted to a desired angle according to the characteristics of the waste, a stopper (not shown) of the stop unit 112 is fitted into a hole of the angle adjusting plate, thus securing the vibrating hopper at the adjusted angle. After the angle of the vibrating hopper is adjusted by the angle adjusting unit, the vibrating hopper is vibrated by a vibrating unit. In order to absorb shocks generated by the vibration, a spring 113 is provided and supported by a spring seat 114 that maintains the horizontal state of the spring. The screw-type adjusting unit 117 is installed between the spring seat and a frame 115, and passes through a hole which is bored in the spring seat 114. In such a state, the screw-type adjusting unit 117 is secured at both sides of the spring support plate using nuts 116. The spring support unit includes an upper spring support plate 118 and a power lock 120. The upper spring support plate 118 supports an upper portion of the spring which maintains the horizontal state. The power lock 120 is mounted to the upper spring support plate 118 to lock a vibrating hopper shaft 119 which is coupled to the vibrating hopper. Further, a hinge unit 121 is installed between the spring seat and the frame, thus providing a hinge action. FIG. 5a illustrates the operation of the vibrating hopper when angles of the vibrating hopper angle adjusting unit and the spring support unit are changed. FIG. 5b illustrates the construction and assembly of the vibrating hopper angle adjusting unit and the spring support unit. FIG. 6 shows the arrangement of the foldable conveyor and the air conveyor for blowing waste, according to the present invention. When the movable trailer 1 is deployed at a predetermined site and treats waste, the blower 8 is installed under the foldable conveyor 14 so as to sort impurities from waste which is separated in multiple stages. Further, the air conveyor 6 is installed at a position where the impurities drop, thus allowing the impurities to be smoothly discharged. According to this invention, the air conveyor 6 is constructed so that both sides thereof are made of a rubber material to reduce noise, and the windbreaks 61 are provided at upper portions of both sides of the air conveyor, thus providing an air path, therefore allowing impurities to be smoothly discharged to a predetermined place.
