Description

  The present invention relates to a carburized material manufactured using waste, a manufacturing method thereof, and a manufacturing facility.

  Conventionally, in steelmaking and steelmaking, a carburized material is introduced into a furnace in order to adjust the carbon content of pig iron and steel. As a carburizing material, there is a material using waste as a material in addition to a material using coke or graphite.

  Conventionally, as a carburized material using waste as a material, there is a material using a residue obtained by thermally decomposing rubber waste such as a waste tire or a waste rubber shoe by combustion or dry distillation (for example, Patent Document 1). reference).

JP 2005-290540 A

  However, since the carburized material of Patent Document 1 is limited to rubber waste, there is a problem that the labor and cost of obtaining the material are relatively high. Moreover, since it is necessary to thermally decompose the material, there is a problem that the fuel cost of the heat source increases.

  Then, the subject of this invention is providing the carburizing material which can reduce the effort and cost of acquisition of material, and can reduce the fuel cost at the time of manufacture, its manufacturing method, and manufacturing equipment.

  In order to solve the above-mentioned problems, the carburized material of the present invention is characterized by forming a combustible material obtained by crushing and sorting both automobile-based waste and construction-related waste.

  According to the above configuration, the combustible material obtained by crushing and sorting both automobile waste and construction waste is used as a material for the carburized material. The combustible material includes a woody material such as waste paper and waste wood and a synthetic resin material such as waste plastic, and is formed of a component containing carbon. Therefore, the carburized material formed by combustible material can be effectively used for adjusting the carbon content of pig iron and steel. Here, the automobile waste refers to waste generated by dismantling a used automobile. In particular, so-called automotive shredder dust, which is a waste mainly composed of resin, glass, and rubber remaining after the removal of air-conditioning refrigerant such as chlorofluorocarbon from used automobiles and recovery of the main metal parts, is crushed by a shredder. Can be used. On the other hand, construction waste refers to waste generated by dismantling buildings and civil engineering structures. Among automotive wastes, automotive shredder dust has hitherto been used for final disposal by landfill, with virtually no reuse. By producing a carburized material using such automobile shredder dust, it is possible to effectively reuse automobile waste. Here, construction waste tends to cause differences in components due to differences in dismantled structures, while automobile waste has relatively little difference in components due to differences in dismantled automobiles. Therefore, a carburized material having relatively stable components can be obtained by using both automobile waste and construction waste as materials. Thus, since the carburized material of the present invention uses automobile waste and construction waste with a large amount of circulation as materials, it is possible to reduce labor and cost of obtaining the materials.

  As for the carburized material of one Embodiment, the said combustible material has a particle size of 40 mm or less.

  According to the said embodiment, since a combustible material has a particle size of 40 mm or less, favorable moldability is obtained when shape | molding. Specifically, since the flammable material has a particle size of 40 mm or less, the melting component such as a synthetic resin contained in the flammable material is sufficiently dissolved by heating during molding, and good moldability is obtained. Here, the particle size of 40 mm or less means that all the metal mesh sieve having a mesh opening of 40 mm passes through JIS Z8801-1. In particular, the combustible material preferably has a particle size of 30 mm or less from the viewpoint of obtaining good shape retention. Specifically, since the combustible material has a particle size of 30 mm or less, the dissolved component dissolved during molding sufficiently wraps around between non-dissolved components such as woody material contained in the combustible material. The carburized material obtained has good shape retention.

  The carburizing material of one embodiment contains 40 to 70 wt% of the combustible material.

  According to the said embodiment, the carburized material which has sufficient carbon amount is obtained by containing 40-70 wt% of combustible materials.

The method for producing a carburized material of the present invention includes a crushing step for crushing both construction waste and automobile waste,
A sorting step of sorting out the material to be processed obtained by crushing the construction waste and the automobile waste, and extracting a combustible material;
And a molding step for molding the combustible material.

  According to the said structure, both a car system waste and a construction system waste are crushed and selected, the combustible material obtained by this is shape | molded, and a carburized material is created. The combustible material includes a woody material such as waste paper and waste wood and a synthetic resin material such as waste plastic, and is formed of a component containing carbon. Therefore, the carburized material formed by combustible material can be effectively used for adjusting the carbon content of pig iron and steel. Here, the automobile waste refers to waste generated by dismantling a used automobile. In particular, so-called automotive shredder dust, which is a waste mainly composed of resin, glass, and rubber remaining after the removal of air-conditioning refrigerant such as chlorofluorocarbon from used automobiles and recovery of the main metal parts, is crushed by a shredder. Can be used. On the other hand, construction waste refers to waste generated by dismantling buildings and civil engineering structures. Among automotive wastes, automotive shredder dust has hitherto been used for final disposal by landfill, with virtually no reuse. By producing a carburized material using such automobile shredder dust, it is possible to effectively reuse automobile waste. Here, construction waste tends to cause differences in components due to differences in dismantled structures, while automobile waste has relatively little difference in components due to differences in dismantled automobiles. Therefore, a carburized material having relatively stable components can be obtained by using both automobile waste and construction waste as materials. Thus, since the carburized material manufacturing method of the present invention uses automobile-type waste and construction-type waste with a large amount of distribution as materials, it is possible to reduce the labor and cost of obtaining the material. Moreover, since a carburized material is manufactured without dry distillation or burning the material, the fuel cost at the time of manufacture can be reduced.

  Moreover, it is preferable that the manufacturing method of the carburized material of this invention uses the combustible material which has a particle size of 40 mm or less among what grind | pulverized and selected both the automobile system waste and the construction system waste. When the combustible material has a particle size of 40 mm or less, good moldability is obtained when it is molded. Specifically, since the flammable material has a particle size of 40 mm or less, the melting component such as a synthetic resin contained in the flammable material is sufficiently dissolved by heating during molding, and good moldability is obtained. Here, the particle size of 40 mm or less means that all the metal mesh sieve having a mesh opening of 40 mm passes through JIS Z8801-1. In particular, the combustible material preferably has a particle size of 30 mm or less from the viewpoint of obtaining good shape retention. Specifically, since the combustible material has a particle size of 30 mm or less, the dissolved component dissolved during molding sufficiently wraps around between non-dissolved components such as woody material contained in the combustible material. The carburized material obtained has good shape retention.

In the forming step, the combustible material mixed in the mixing step is heated and formed into a rod-like body by extrusion.

In the drive-side eccentric bearing unit 130, when the drive shaft 133 is rotationally driven by a motor, the eccentric plate 131 rotates eccentrically around the drive shaft 133, and accordingly, the eccentric turning member 132 is eccentric about the swing shaft 133. Turn. Thereby, the strip-shaped sieve plate 116 connected to the eccentric turning member 132 swings up and down. Each strip-shaped sieve plate 116 is set to have a phase difference of 180 degrees with respect to the adjacent strip-shaped sieve plate 116. Therefore, when a certain strip-shaped sieve plate 116 is positioned at the uppermost point, the strip-shaped sieve plate 116 adjacent thereto is positioned at the lowest point.

  When the swing sorter 14 is operated, the strip-shaped sieve plate 116 having the above-described configuration is driven to swing, and the workpiece is input into the casing 111 from the input port 112. The thrown object to be processed is unwound by the strip-shaped sieve plate 116 that is driven to swing, and fine particles 122 such as earth and sand and nails contained in the object to be processed fall downward from the sieve hole 119a, and the fine particles It is discharged from the object discharge port 114. Among the objects to be processed, lightweight objects 123 such as fiber scraps, paper, wood pieces, and plastic sheets receive a force from the strip-shaped sieve plate 116 that is driven to swing, slide on the upward inclined portion 118a of the saw blade 118, and the saw blade 118. It is conveyed upwardly while being inherited by the downward inclined portion 118b. The transported lightweight object 123 falls from the other end of the strip-shaped sieve plate 116 and is discharged from the lightweight object discharge port 115. Among objects to be processed, heavy objects 121 such as metal pieces, ceramic pieces, hardware, empty cans, PET bottles, blocks, stones, and shoes move downward while rolling or sliding on an inclined strip-shaped screen 119 to form strips. It falls from one end of the sieve plate 116 and is discharged from the heavy material discharge port 113. As described above, the lightweight object 123 transported on the strip-shaped sieve plate 116 upward is mainly non-repulsive such as fiber waste, paper, plastic film, or the like. On the other hand, the heavy object 121 that moves the strip-shaped sieve plate 116 downwardly is mainly repulsive such as metal, stone, or hard plastic.

  The blower 125 loosens the object to be processed input from the input port 112 of the casing 111 with an air flow, and blows a lightweight object 123 such as a tape or a sheet to the other end side on the strip-shaped sieve plate 116 for selection. Facilitate.

The magnetic material removed by the magnetic separator 21 is collected in the magnetic material yard 22. The to-be-processed object from which the magnetic substance is removed from the heavy article 121 is sorted and removed by the sorter while the non-combustible substance other than the magnetic substance is sorted by the sorter. Thus, the hand sorting line 3 corresponds to the second sorting line, and the process by the hand sorting line 3 corresponds to the second sorting process. The incombustibles removed by the sorter's manual sorting are collected in a ceramic yard 23, an aluminum can yard 24, a plastic bottle yard 25, and a bottle yard 26 according to the respective types.

The temperature of the object to be processed is increased with the processing by the particle size adjuster 27, and the temperature of the object to be processed is lowered by rapidly diffusing the heat of the object to be processed by the vibration by the vibration conveyor 28. Thereby, ignition of the to-be-processed object containing resin is prevented. As shown by the arrow A, the object to be processed whose temperature is lowered while being conveyed by the vibration conveyor 28 is sent to the fine particle conveyor 81. The object to be processed crushed by the particle size adjusting machine 27 joins and transports the fine particles separated by the vibrating sieve 13 and the fine particles sorted by the swing sorter 14.

The workpiece guided to the aluminum magnetic separator 35 is placed on the belt conveyor 141 by the feeder 153. When the workpiece is conveyed to the other end of the belt conveyor 141, eddy currents are generated in the non-ferrous metal in the workpiece due to the magnetic field of the rotating magnet drum 146. Due to the repulsive force generated between the magnetic field generated in the non-ferrous metal by the eddy current and the magnetic field of the magnet drum 146, the non-ferrous metal is repelled in the tangential direction of the pulley 143 as indicated by an arrow F2. The non-ferrous metal is discharged from the non-ferrous metal discharge port 151 on the side far from the pulley 143 and stored in the aluminum container 36. The workpiece to which the non-ferrous metal is blown off is dropped below the pulley 143 and discharged from the workpiece discharge port 152.

  FIG. 11 is a schematic diagram showing the particle size selection / vinyl chloride removal line 6. The particle size sorting / vinyl chloride removal line 6 sorts the material of the carburized material and the material of the RPF from the workpiece, and removes the chlorine-based resin from the workpiece. As shown by the arrow E, the workpieces sent from the specific gravity difference sorting line 5 are put into the wave type sieve 51 by the conveyor.

  FIG. 12 is a cross-sectional view showing the wave type sieve 51. The wave-type sieving machine 51 effectively sorts small-diameter items of 5 mm or less using a flexible sieve body. In this wave type sorter 51, a casing 181 having a substantially parallelogram in longitudinal section is supported on a support frame 182 via an elastic body 183. The casing 181 is supported while being inclined from one end to the other end in the longitudinal direction, and a workpiece inlet 184 is provided at the upper end on the upper side in the inclination direction. The lower side portion of the casing 181 is a small-diameter object discharge port 186 that is substantially entirely open and discharges a small-diameter object that is passed through a sieve. A large-diameter object discharge port 185 for discharging a large-diameter object remaining on the sieve is provided at the lower upper end of the casing 181 in the inclination direction. An exciter 188 that generates vibration is provided on the upper portion of the housing 181. In the casing 181, a flexible sieve body 190 is disposed from the lower part of the inlet 184 to the lower part of the large-diameter object outlet 185. The sieve body 190 is a net body formed of an elastomer such as urethane rubber, and has an opening of 5 mm. The mesh body forming the sieve body 190 may be formed by weaving elastomer fibers, or may be formed by providing a large number of through holes in the elastomer film. The sieve body 190 is supported by a plurality of amplification arms 191 installed in the housing 181. The amplification arm 191 is attached to a support beam 192 spanned in the transverse direction in the housing 181 so that the tip thereof faces the large-diameter object discharge port 185 side. A plurality of support beams are installed in the longitudinal direction in the housing 181, and a plurality of amplification arms 191 are attached to each of the support beams 192 side by side in the transverse direction.

  When the wave sieve 51 is operated, the casing 181 is vibrated by the vibration generator 188, and this vibration is transmitted to the support beam 192 fixed to the inner side surface of the casing 181. The vibration of the support beam 192 is amplified by the amplification arm 191 and transmitted to the sieve body 190 supported by the tip of the amplification arm 191. The sieve body 190 vibrates and repeats bending and extension. In this state, an object to be processed is input from the input port 184 of the casing 181, and the input object to be processed inclines inside the casing 181 while repeating jumping and dropping by the sieve body 190 that vibrates and repeats bending and extension. Move down the direction. In the process of moving on the sieve body 190 while repeatedly jumping and dropping, the object to be treated is separated from a small-diameter object of 5 mm or less and passes through the mesh or through-hole of the sieve object 190, while the small-diameter object of 5 mm or more is sieved. It remains on the body 190. According to this wave type sieving machine 51, since the object to be processed repeatedly jumps and drops by the sieve body 190 that repeatedly bends and extends, even if the object to be processed contains moisture, it adheres to the sieve body 190. Sorting can be performed by passing a small-diameter object through the through hole without causing clogging. The small-diameter object that has passed through the sieve body 190 is discharged from the small-diameter object discharge port 186 of the housing 190 and collected in the first material yard 52. The small-diameter objects of 5 mm or less collected in the first material yard 52 are mainly combustible materials such as combustible resin, wood waste, and paper waste. The large-diameter object remaining on the sieve body 190 is discharged from the large-diameter object discharge port 185. The large-diameter product separated by the wave-type sieving machine 51 is sent to the quantitative supply machine 53 together with the light-weight product from the crushing / sorting line 2 indicated by the arrow B. Thus, the wave type sieve 51 corresponds to the fourth sorting device, and the process using the wave type sieve 51 corresponds to the fourth sorting process. Here, the opening of the sieve body 190 of the wave type sieve 51 may be any size within a range of 5 mm or less and 3 mm or more.

  A certain amount of the processing object temporarily stored in the fixed amount feeder 53 is discharged per unit time, and is supplied to the sorting feeder 54 via the conveyor. The sorting feeder 54 includes a trough that receives the object to be processed, a sieve body that is loaded with the object to be processed from the trough, and that is inclined with its tip facing downward, and a vibrator that vibrates the sieve body. The sieve body is formed by arranging a plurality of comb-tooth members in a stepped manner by fixing the base end portions of a plurality of rod members arranged in parallel to each other to a fixing member extending in the width direction. . The interval between the bar members of the comb-teeth member is set to 30 mm. The object to be processed put on the sieve body is unraveled by vibration of the sieve body, and a small-diameter object having a particle size of 30 mm or less falls through the gaps of the comb-teeth member of the sieve member and is removed from the object to be processed. Is done. The object to be processed from which the small-diameter object has been removed is guided from the sorting feeder 54 to the optical sorter 56. Small-diameter objects of 30 mm or less sorted by the sorting feeder 54 are collected in the second material yard 55. The small-diameter objects collected in the second material yard 55 are mainly combustible materials such as combustible resin, wood waste and paper waste. Thus, the sorting feeder 54 corresponds to the fifth sorting device, and the process using the sorting feeder 54 corresponds to the fifth sorting process.

A lens of the near-infrared camera 207 is arranged between each pair of lamps of the irradiating unit 206 so as to receive near-infrared light from directly below.

  When the object to be processed is conveyed by the conveyer 201 and reaches below the optical unit 202, the irradiation unit 206 of the optical unit 202 irradiates the object with near infrared rays, and the irradiated near infrared rays are reflected by the object to be processed. The lens of the near infrared camera 207 receives the reflected wave. The near-infrared camera 207 receives the reflected near-infrared wave and outputs information indicating the wavelength and intensity of the reflected near-infrared wave to the control unit 204. The control unit 204 analyzes the wavelength and intensity of the reflected wave from each object to be processed based on the information input from the near infrared camera 207, and discriminates the material of the object to be processed based on the spectrum distribution pattern. If the identified material is a chlorine-based resin such as vinyl chloride, the control unit 204 removes the object to be processed. That is, at the timing when the chlorinated resin workpiece reaches the end of the transfer conveyor 201, the control unit 204 outputs the operation signal S2 to the air gun 203 to operate the air gun 203, and the compressed air is processed into the chlorinated resin workpiece. Inject toward The object to be treated of chlorinated resin is blown off by receiving compressed air, and is collected in a collection chamber 208 provided on the side far from the end of the transfer conveyor 201. The object to be processed other than the chlorinated resin falls downward from the end of the transfer conveyor 201 and is recovered in a recovery chamber 209 provided on the side close to the end of the transfer conveyor 201. The chlorinated resin separated by the optical sorting device 56 is accommodated in a vinyl chloride container 57 and finally disposed. The object to be processed from which the chlorine-based resin has been separated and removed is collected in the RPF material yard 58 as an RPF material. The main component of the RPF material is a combustible material such as combustible resin, wood waste and paper waste.

The carburized material forming machine 66 guides the supplied combustible material to the processing chamber while kneading with two screws, and kneads and compresses the material in the processing chamber. The combustible material kneaded and compressed in the processing chamber is melted by the plastic that is the dissolved component by the frictional heat generated by the kneading and compression and the heat of the heater of the extruded face plate. The melted plastic becomes a binder between the woody material such as waste paper and waste wood, which is an insoluble component of the combustible material, and another material, and is extruded from the extrusion nozzle and formed into a rod shape. The rod-like body extruded from the extrusion nozzle of the carburized material forming machine 66 is cut into a predetermined length by a cutter installed adjacent to the extruded face plate, and the carburized material is completed. The carburized material produced by the carburized material forming machine 66 is conveyed by a conveyor and placed in the first product yard 67. The carburized material forming machine 66 of the carburized material forming line 7 performs a material extruding step, and solidifies other insoluble materials using the dissolved component of the combustible material as a binder to produce a carburized material. As long as it is a thing, another molding machine may be sufficient. As the carburized material molding machine, a ring die type molding machine can be used in addition to the screw type molding machine. Moreover, although the small diameter thing of the 1st material yard 52 and the small diameter thing of the 2nd material yard 55 were mixed by the fixed quantity feeder 61, you may mix by another method. For example, small-diameter items may be mixed by a heavy machine in a yard.

The RPF molding machine 75 is a twin-screw type molding machine, and kneads, compresses and molds while preventing back flow of material by two screws arranged in parallel. The RPF molding machine 75 includes a processing chamber that accommodates two screws, and an extrusion surface plate that is disposed on the end surface of the processing chamber so as to face the tip of the screw and incorporates an extrusion nozzle and a heater. The RPF molding machine 75 guides the supplied material to the processing chamber while kneading with two screws, and kneads and compresses the material in the processing chamber. The material kneaded and compressed in the processing chamber is melted by frictional heat generated by kneading and compression and the heat of the heater of the extrusion face plate, and the dissolved component such as plastic is dissolved. It becomes a binder of wood chips and is extruded from an extrusion nozzle and formed into a rod shape. The rod-like body extruded from the extrusion nozzle of the RPF molding machine 75 is cut into a predetermined length by a cutter installed adjacent to the extrusion face plate, and the RPF is completed. The RPF formed by the RPF molding machine 75 is cooled in the process of being conveyed by the water-cooled cooling conveyor 76 and collected in the second product yard 77. The RPF molding machine 75 of this RPF molding line 8 performs the mixing, kneading, heating, and extrusion processes of materials, and solidifies wood chips, paper scraps, etc., which are insoluble components, using a dissolved component as a binder to produce RPF. Any other molding machine may be used. As the RPF molding machine, a ring die molding machine can be used in addition to the screw molding machine.

Table 1 is a table | surface which shows the composition of the Example of the carburized material manufactured with the manufacturing method and manufacturing equipment of the said embodiment. Table 2 shows the industrial analysis results of the carburized materials of the examples. The carburized material of this example is manufactured by putting construction waste and automobile waste having substantially the same mass into the recycling facility 1. The carburized material of the example had a lower heating value of 6600 Mcal / t and a higher heating value of 6900 Mcal / t. According to these, it can be said that the carburized material of the example can be sufficiently used as a carburized material for iron making or steel making.

  In the manufacturing method of the above embodiment, the input automobile waste and construction waste are crushed to a size of 150 mm or less by the coarse crusher 11, and the heavy material 121, the fine particles 122, and the light weight are obtained by the swing sorter 14. The product is crushed to 50 mm or less by the particle size adjuster 27, the metal is removed by the metal removal line 4, and the high specific gravity, low specific gravity and fine particles are selected by the specific gravity difference sorter 43 and low specific gravity. A combustible material was produced with a small-diameter product having a particle size of 5 mm or less extracted by the wave type sieve 51 and a small-diameter product having a particle size of 30 mm or less extracted by the sorting feeder 54. If a combustible material having a particle size of 30 mm or less is obtained using construction waste as a material, the crushing dimension and the selected particle size in each step may be other values. Further, the particle size of the combustible material made of automobile shredder dust and construction waste may be 40 mm or less. Moreover, in the said embodiment, although RPF was manufactured with the carburizing material by using automobile system waste and construction system waste as a material, it is not necessary to manufacture RPF.
