[0001]

[Industrial applications]

 The present invention relates to a waste material crushing treatment device and a waste material crushing treatment system for finely crushing waste material such as concrete debris generated by the dismantling of a concrete structure or the like for reuse as aggregate.

[0002]

[Prior art]

 A conventional waste material crushing treatment system has a primary crusher 51a and a secondary crusher 51b, as shown in FIGS. 7, 8 and 9, and a sorting machine 52 is provided between these crushers. There is. The primary crusher 51a and the sorting machine 52 are a first conveyor line 53 including two belt conveyors 54a and 54b, and the sorting machine 52 and the secondary crusher 51b are a second conveyor line including a belt conveyor 56. It is relayed at 55 each. In the primary crusher 51a, for example, the waste material 60 such as concrete debris piled up in the waste material storage area A is primary crushed by the loading hydraulic excavator D, and the first conveyor line 53 separates the primary waste material 61 from the sorter. It is transported to 52. Next, in the sorting machine 52, the primary waste material 61 is sorted into small particle size primary waste materials of a predetermined particle size or less according to particle size 63a and 63b and large particle size primary waste material 62 (Fig. 9), and further smaller particle size. The primary waste materials 63a and 63b having a diameter are delivered to the recycled aggregate storage sites B and C by the respective delivery conveyors 59a and 59b, and the primary waste material 62 having a predetermined grain size or more is provided to the secondary crusher 51b at the second conveyor line 55. It is transferred to and crushed to the secondary. The secondary waste material 64 is returned to the first conveyor line 53 by a third conveyor line 57 composed of belt conveyors 58a and 58b, where it merges with the primary waste material 61 and is conveyed to the sorting machine 52 again for sorting. To be processed.

[0003]

[Problems to be solved by the device]

 However, the waste material crushing treatment system requires the second conveyor line 55 for conveying the waste material 62 from the sorting machine 52 to the secondary crusher 51b, but the input port of the secondary crusher 51b is provided at a high place. Therefore, in order to convey and load the waste material 62 into the input port without slipping on the belt conveyor, it is necessary to limit the inclination angle of the conveyor, and a belt conveyor with a short inclination cannot be used. For this reason, as shown in FIGS. 7 and 8, a long inclined conveyor must be used, which inevitably increases the total installation area. Further, since the third conveyor line 57 for returning the total amount of the secondary waste material from the secondary crusher 51b to the first conveyor line 53 on the upstream side of the sorting machine 52 is provided, the throughput of the sorting machine 52 is increased. Not only this, but the third conveyor line 57 itself complicates the entire structure and further increases the installation area. Moreover, not only a large-capacity power generation and power supply facility is required for the above equipment, but also a large amount of cost is required for maintenance and transfer of the entire system.

The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a waste material crushing treatment apparatus and a waste material crushing apparatus that can make the whole compact while maintaining the functions of the conventional apparatus. To provide a processing system.

【Example】

 Next, specific examples of the waste material crushing treatment device and the waste material crushing treatment system of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan layout view showing an example of the waste material crushing treatment system of the present invention, FIG. 2 is a side layout view of FIG. 1, and FIG. 6 is a flow chart thereof.

In FIG. 1 and FIG. 2, A is a storage place for waste materials 3 such as concrete debris. In addition, B and C are storage areas for recycled aggregates, and B is a pile of recycled crushed stone and C is a pile of recycled sand. D is a loading hydraulic shovel, 1a is a primary crusher, and the loading hydraulic excavator D loads the waste material 3 in the storage area A into the loading port 20 of the primary crushing machine 1a. Reference numeral 1b is a secondary crusher, and 2 is a sorting machine having two stages of vibrating screens with different openings. This sorting machine 2 is mounted on a common frame in contact with the upper portion of the secondary crushing machine 1b. 4a and 4b are relay conveyors (conveying means), and 5a and 5b are payout conveyors. The relay conveyors 4a and 4b relay the lower outlet of the primary crusher 1a and the input port 21 of the upper portion of the sorting machine 2 described above, and the primary crusher 1a crushes the primary crusher 1a. The waste material is transported and input to the input port 21 of the sorting machine 2. In the sorting machine 2, as shown in FIG. 6, first, the primary waste material 11 is divided into a large particle size primary waste material 12 and a small particle size primary waste material 13 which are larger than the mesh size by a coarse screen 24a. Further, the small-sized waste material 13 is sorted into a residue 13a remaining on the screen 24b and a passing material 13b passing therethrough by a screen 24b having a mesh size larger than that of the screen 24a. The payout conveyors 5a and 5b are paying out to the storage areas B and C, respectively. On the other hand, as shown in FIGS. 1 and 2, the large-sized primary waste material 12 is directly charged into the secondary crusher 1b for secondary crushing, merged with the residue 13a, and conveyed to the storage B. There is.

Next, the sorting machine 2 and the secondary crushing machine 1b will be described in more detail. FIG. 3 is a front view showing a partial cross section of the secondary crusher and the sorting machine, FIG. 4 is a plan view thereof, and FIG. 5 is a right side view thereof. In FIGS. 3 and 5, reference numeral 15 denotes a common mount, on which the secondary crusher 1b and the sorting machine 2 are installed so as to be located relatively above the secondary crusher 1b. ing.

First, this sorter 2 is of a vibrating screen type and is composed of the following elements (see FIG. 3). That is, it is a frame 23 that is movably supported by the common mount 15 via a vibration isolating rubber 22 that is fixed on the common mount 15, and is arranged in two stages vertically inside the frame 23. , An upper screen (opening 40 mm) 24a and a lower screen (opening 10 mm) 24b fixed to the frame 23, and an upper screen residue (large-sized primary waste material) 12 fixed to the frame 23, respectively. Upper screen residue discharge port 25 that discharges, lower screen residue discharge (small particle primary waste material) 13a that discharges lower screen residue discharge port 26a, and lower screen residue (small particle primary waste material) Lower screen passing matter discharge port 26b for discharging 13b, chutes 27a, 27b, 27c for relaying the respective primary waste materials 12, 13a, 13b, and above the frame body 23. Is secured to, is what is consists exciter device 28 for generating a vibration to said each screen 24a, 24b. The upper screen residue discharge port 25 and the lower screen residue discharge port 26a are arranged in front of each of the screens 24a and 24b, that is, on the side of the secondary crusher 1b, and the lower screen pass-through discharge port 26b is It opens below the lower screen 24b. Further, in each of the chutes, a chute 27a is arranged at the tip of the discharge port 25, relays the screen residue 12 to the charging port 41 of the secondary crusher 1b, and the chute 27b is arranged at the tip of the discharge port 26a. The lower screen residue 13a is relayed to the confluent discharger 16 and the chute 27c is disposed below the lower screen 24b to relay the lower screen passing material 13b to the payout conveyor 5b. Further, the vibrating device 28 includes a base plate 29 fixed to the upper end of the frame body 23, and a pair of base plates 29 arranged on both sides of the base plate 29 via an upper screen 24a as shown in FIG. Drive motors 30a, 30b, a pair of speed reducers 31a, 31b for transmitting power from the motors 30a, 30b and reducing the number of revolutions, and fixed on the base plate 29. 31b and a vibration generator 32 that generates vibrations by receiving power. Therefore, when the drive motors 30a and 30b rotate, the sorting machine 2 can transmit rotational power to the eccentric weight (not shown) attached to the rotary shaft of the vibration generator 32 via the speed reducers 31a and 31b, and the eccentricity can be increased. By rotating the weight, it becomes possible to vibrate the entire frame 23 diagonally in the front-rear direction as shown by an arrow 33 in FIG. Due to this vibration, the primary waste material 12 having a particle size larger than 40 mm in the primary waste material 11 remains on the upper screen 24a, and the primary waste materials 13a and 13b having a particle size smaller than 40 mm pass through the upper screen 24a. As a result, the primary waste material 13b having a particle size smaller than the openings of the lower screen 24b further passes through the lower screen 24b. In this way, the primary waste material 11 can be sorted out, and the residues 12 and 13a on the screens 24a and 24b advance toward the discharge ports 25 and 26a by vibration as shown by the arrow 33 and are discharged. The passing matter 13b that has also passed through 24b falls from the lower screen passing matter discharge port 26b through the chute 27c to the payout conveyor 5b, and is conveyed to the storage area C as recycled aggregate.

Next, the secondary crusher 1b will be described. The secondary crusher 1b is a jaw crusher type crusher, and as shown in FIG. 3, the residue 12 on the upper screen 24a of the sorting machine 2 passes through the chute 27a to the secondary crusher. It is installed on the common pedestal 15 via the base plate frame 42 so that the height is such that it is inserted into the input port 41 of 1b. The secondary crusher 1b is composed of the following elements. A drive motor 43 disposed on one side of the suspension base plate frame 42, a speed reducer 44 that transmits the power of the drive motor 43 and reduces the rotation speed, and is composed of a pulley and a V-belt are shown in FIG. As described above, the eccentric rotation shaft 45 that receives the rotational force from the speed reducer 44 on one end side, the eccentric rotation shaft 45 mounted on the other end side of the eccentric rotation shaft 45, and the eccentric rotation shaft 45. And a fixed crush plate 47b fixed to the base plate frame 42 so as to face the movable crush plate 47a. Both of the crush plates 47a and 47b have vertical groove-like crush teeth formed on the surface so that the waste material is easily crushed. As shown in FIG. 3, the fixed crush plate 47b is vertically and the movable crush plate is movable. 47a is obliquely attached so that its lower end side is close to the fixed crush plate 47b side. Therefore, by the rotation of the eccentric rotation shaft 45, the movable crush plate 47a is driven in an elliptic motion downward as shown by an arrow 48, and the supplied upper screen residue 12 cooperates with the fixed crush plate 47b. Since it is compressed, it can be crushed. Then, the secondary crushed secondary waste material 14 is discharged from the secondary waste material discharge port 49, and falls through the merge discharge device 16 to the lower payout conveyor 5a. The confluent discharger 16 is attached to the common mount 15, receives the secondary waste material 14 and the lower screen residue 13a on the lower screen 24b and merges them, and then discharges them to the payout conveyor 5a. Further, the payout conveyor 5a is conveyed to the storage area B as recycled aggregate.

At this time, the secondary waste material 14 naturally includes particles having a particle size of 10 mm or less. However, the recycled aggregate produced in this way is mainly used as a roadbed material or a landfill material. If aggregates with a large particle size of 10 to 40 mm are used for compacting after laying or charging, it is also recommended to mix an appropriate amount of aggregates of 10 mm or less to fill the gap between the aggregates. It is normal, and mixing the primary crushed material of 40 to 10 mm, which has been selected and extracted as described above, with the secondary crushed material of various particle sizes of 40 mm or less that impairs the utility value as recycled aggregate. Rather, it can even be said to be convenient. The maximum particle size of the secondary waste material 14 can be adjusted by adjusting the position of the movable crushing plate 47a.

In the apparatus having the above structure, the waste material 3 thrown into the primary crusher 1a by the loading hydraulic excavator D is crushed into primary pieces, and the waste material 11 is transferred to the upper part of the sorting machine 2 by the relay conveyors 4a and 4b. It is conveyed to and input into the input port 21. In the sorting machine 2, while vibrating by the vibration generator 28, the primary waste material 11 is sorted and extracted in predetermined particle size ranges by the two-stage screens 24a and 24b. That is, the large-sized primary waste material 12 having a diameter of 40 mm or more on the upper screen 24a is introduced from the outlet 25 through the chute 27a into the inlet 41 of the secondary crusher 1b, and by both crush plates 47a and 47b. Secondary crushing is performed to 40 mm or less, and the secondary waste material 14 is discharged to the confluent discharger 16 below. The small-sized primary waste material 13a of 10 to 40 mm which has passed through the upper screen 24a but does not pass through the lower screen 24b is also discharged from the discharge port 26a through the chute 27b to the merge discharge device 16, It joins with the secondary waste material 14 that has been subjected to secondary crushing, and is conveyed to the storage area B by the delivery conveyor 5a. Further, the small-sized primary waste material 13b having a diameter of 10 mm or less which has also passed through the lower screen 24b is discharged from the discharge outlet 26b through the chute 27c below, and is conveyed to the place C by the discharging conveyor 5b.

As described above, in the above embodiment, the residue 12 on the upper screen 24a of the sorting machine 2 is disposed so that the residue 12 can be directly fed to the feeding port 41 of the secondary crusher 1b. Since it is integrated on the common mount 15, the second conveyor line for transporting large-sized primary waste material from the sorting machine 2 to the secondary crusher 1b, which was necessary in the conventional device, can be omitted. . Further, the residue 13a remaining on the lower screen 24b of the sorter 2 and the secondary waste material 14 secondarily crushed to a particle size smaller than the opening of the upper screen 24a by the secondary crusher 1b are combined and carried out. Therefore, the third conveyor line, which was used to transport the secondary waste material from the secondary crusher 1b to the first conveyor line for transporting the primary waste material on the upstream side of the sorting machine 2, is omitted. You can Therefore, the whole system can be simplified and the installation space can be reduced. Furthermore, not only equipment cost but also required power can be reduced, so operating and maintenance costs can be reduced, which is economical.

Further, the total amount of the primary waste material 11 is not charged into the secondary crusher 1b, but only the large particle size primary waste material 12 remaining on the upper screen 24a of the sorting machine 2 is charged. The load on the secondary crusher 1b can be reduced, and since the secondary crushed secondary waste material 14 is not returned to the upstream side of the sorter 2, the load on the sorter 2 can also be reduced. Therefore, both devices can be downsized.

Further, a jaw crusher is used as the secondary crusher 1b. Compared to other rotary crushers, impant crushers, etc., this jaw crusher can generally have a lower height from the upper inlet 21 to the lower outlet 49, so it can be made more compact, and the device design is compact and economical. Can be achieved.

Then, two kinds of screens 24a, 24b having different openings are arranged in two stages in the vertical direction so that the coarse screen 24a is arranged above, and the residue on each screen 24a, 24b is arranged. Since two discharge ports 25 and 26a for discharging 12 and 13a respectively and a discharge port 26b for discharging the passing material 13b that has also passed through the two-stage screen 24b are provided, stepwise for each specific particle size range. It is possible to sort, and it is possible to extract various kinds of aggregates. Therefore, it can be applied to various uses of recycled aggregate. In addition, since the secondary waste material 14 (0 to 40 mm) is merged with the residue 13a (10 to 40 mm) on the lower screen 24b, when it is reused as a roadbed material or landfill aggregate, a large particle size is used. It is possible to reduce the work of mixing the large particle size aggregate and the small particle size aggregate to fill the gaps of the aggregate.

[0024]

Since they are merged, the conveyor line that returns to the upstream side of the conventionally installed sorter can be omitted and the load on the sorter can be reduced. Therefore, the device can be made compact.

According to the second aspect, since it is possible to perform the stepwise selection for each predetermined particle size range according to the opening of the screen, it is possible to cope with various uses of the recycled aggregate.

According to claim 3, the height from the upper input port of the waste material to the lower discharge port of the crushed material can be made lower than that of the rotary crusher, the impant crusher, etc., so that the apparatus can be further downsized.
