The present invention relates to a crushing sorting device of construction waste, and more particularly to a crushing sorting device of construction waste for recycling the waste resources discarded at the construction site.

Construction wastes generated during the construction or demolition process consist of waste concrete, ascon, wood, and plastics, and most of them are handled by construction waste intermediate treatment companies, but most of them are disposed of because they are not recycled due to lack of processing technology. As the existing landfills saturate and have difficulty in securing new landfills, they are becoming an urgent problem.

For reference, if the construction waste is to be recycled into landfill, subbase, road substrate, or cover, the waste management law specifies that the maximum diameter is 100mm or less and the foreign matter content is 1% or less by volume. It can not be crushed to the size of less than 40㎜ and waste sand, waste plastic, etc. remain in a small amount, there is a limit to use as a road base material.

In the device for: installed on the lower end of the hopper 10, screw conveyor for crushing and transporting the injected waste; A roller mechanism (30) having different diameters on the downstream side of the screw conveyor (20) and provided with an upper roller (31) and a lower roller (32) being opposed to each other; A magnet 40 installed downstream of the roller mechanism 30 and attaching metallic foreign matter; A sorting means (50) installed on the downstream side of the magnet (40) and sorting and collecting in multiple stages for each particle size; And a foreign material collector (60) installed in the middle or the end of the sorting means (50) and blowing foreign matters to the blower (65) at one end.

As another feature of the invention, the roller mechanism 30 is further provided with a means for adjusting the height of the shaft 36 of the upper roller 31, the height adjusting means supports the shaft 36 and the frame ( 15 is supported on the frame 15 so as to be able to move up and down, the spring 73 interposed between the support 72 and the frame 15, and the lower end of the support 72, Interlocking spiral shaft 75; A handle 76 is mounted to rotate the spiral shaft 75.

As another feature of the present invention, the roller mechanism 30 is further provided with a means for varying the rotational inertia force of the upper roller 31, the inertial variable means is a spiral installed in the radial direction toward the shaft 36 A shaft 85 and a weight body 80 engaged with the spiral shaft 85 to enable positional change are provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the connection of the main part of the device according to the invention, Figure 2 is an enlarged front view showing the roller mechanism of the device according to the invention.

The present invention relates to a device for sorting materials of varying particle sizes from construction waste introduced into the hopper 10 on one frame 15 and discharging them to each conveyor 11, 12, 13, 14. Although the frame 15 is omitted in FIG. 1 to help understand the connection of the main parts, the present invention provides the main functional unit from the hopper 10 to the conveyors 11, 12, 13, 14 in one frame ( 15) Put them all together so that the whole process is done in one batch. The conveyor 11, 12, 13, 14 which illustrate by four in this invention may increase or decrease according to the particle size of the material required in the field.

According to the present invention, a screw conveyor 20 for crushing and transferring the input waste is installed at the bottom of the hopper 10. A circular outlet is formed at the bottom of the hopper 10, and the screw conveyor 20 is installed to communicate with the inside and the outside. Accordingly, the screw conveyor 20 is crushed to a predetermined size or less even if large and small construction waste is put into the hopper 10 and transferred to the roller mechanism 30 which is the next process.

In addition, the roller mechanism 30 according to the present invention has an upper roller 31 and a lower roller 32 which are provided on the downstream side of the screw conveyor 20 as main components, and upper and lower rollers 31 and 32 having different diameters. Are opposed to each other to maintain a constant clearance and are driven by respective motors 33 and 34. As shown in FIG. 2, the upper roller 31 having a large diameter gives the unevenness 31a large, and the lower roller 32 having a small diameter may have small unevenness. In this way, as the diameters of the rollers 31 and 32 are different and driven at different speeds, the crushing force is enhanced. The rollers 31 and 32 have a good hollow structure in order to reduce power consumption, but minimize the hollow in consideration of crushing force and durability. Each motor 33, 34 connects with rollers 31, 32 via a sprocket-chain transmission mechanism.

In particular, the upper roller 31, which influences the crushing force, contacts the brush 35 in the same axial direction so that the unevenness 31a is not filled with stones or soil. The brush 35 uses a wire form of steel.

At this time, the roller mechanism 30 may further include a means for adjusting the height of the shaft 36 of the upper roller 31, the height adjusting means is a support 72, a spring 73, a spiral shaft ( 75) and the handle 76. The support 72 supports the shaft 36 as a bearing and is mounted on the frame 15 so as to be able to lift and lower. The spring 73 is interposed between the support 72 and the frame 15. With the support 72 as a two-stage structure, the lower end with a small cross section is inserted into the groove of the frame 15, and the spring 73 is in contact with the upper end with a large cross section. The spiral shaft 75 is engaged with the frame 15 to be in contact with the lower end of the support 72, and the handle 76 is mounted to rotate the spiral shaft 75. As such, when the spiral shaft 75 is turned up and down by turning the handles 76 at both ends of the shaft 36, the support 72 and the upper roller 31 are interlocked thereto. Since the up and down stroke distance of the upper roller 31 is very small, precise adjustment is not necessary, but in some cases, a scale capable of comparing the height difference between the two sides of the upper roller 31 may be provided.

Further, according to the present invention, a magnet 40 to which metallic foreign matter is attached is provided downstream of the roller mechanism 30. The magnet 40 is irrelevant whether it is a permanent magnet or an electromagnet, and is installed to a sufficient size over the width of the conveying passage through which the material is transferred. To facilitate the collection of the attached magnetic material, the magnet 40 has a structure that can be detached over the width of the transfer passage. The transfer passage is made of a metal material and is detached by the magnetic force of the magnet 40.

In addition, according to the present invention, the sorting means 50 for classifying and collecting in multiple stages by particle size is installed downstream of the magnet 40. The three sorters 51, 52, 53 constituting the sorting means 50 each include a screen having a different mesh and a chute below it. The upstream sorter 51 for dropping the particles having the smallest size is preferably configured to oscillate by adding the vibrator 55. Conveyors 11, 12, 13, 14 are installed below each sorter 51, 52, 53 to convey the sorted material to a desired place.

As an example of the present invention, the upstream sorter 51 is 10 mm, the middle sorter 52 is 11-21 mm, the downstream sorter 53 is 21-30 mm, and finally 31- It can be designed to collect a size of 40 mm.

In addition, according to the present invention, the foreign matter collector 60 is provided. The foreign material collector 60 is installed in the middle or the end of the sorting means 50 as a cylindrical net 62, and adopts a configuration for blowing foreign matter to the blower 65 at one end. For example, the cylindrical net 62 may be installed between the middle sorter 52 and the downstream sorter 53, and a foreign matter may be collected by covering a separate bag on the opposite side where the blower 65 is installed.

The cylindrical net 62 may be configured to rotate using the motor 64, and also selects the material having a predetermined size, such as other sorters 51, 52, 53, and sends the same to the conveyor 14. Have The mesh of the cylindrical net 62 is made to be the middle size of the screen upstream and downstream.

Figure 3 is a front sectional view and a side view showing the inertial variable means of the device according to the invention.

The roller mechanism 30 of the present invention may further include a means for varying the rotational inertia force of the upper roller 31. The inertial variable means includes a spiral shaft 85 installed in a radial direction toward the shaft 36 and a weight body 80 engaged with the spiral shaft 85 so as to allow a positional change. Although not shown, the weight 80 may be formed with a plurality of holes on the outer circumferential surface to facilitate turning with a tool such as a driver. Spiral shaft 85 is a round spiral or trapezoidal spiral so as to be less affected by the dust of the workplace, and firmly fixed so as not to rotate in a somewhat recessed state on one surface of the upper roller (31).

Accordingly, as the two side weights 80 are turned away from the center of the shaft 36, the inertia force fluctuates and shocking fracture is possible. Although two weights 80 are illustrated in the figure, a configuration of installing three or four is also possible.

4 is a schematic view showing an overall configuration according to the present invention.

When the motor 25 is operated while putting construction waste into the hopper 10, the screw conveyor 20 is rotated to discharge the waste to a predetermined size or less, and continues to pass through the upper and lower rollers 31 and 32 in a finer state. To be crushed. Subsequently, the magnetic material is filtered while passing through the magnet 40, and is classified into granularities set by the separators 51, 52, 53 and the foreign matter collector 60 to the conveyors 11, 12, 13, 14. When transported, it becomes recycled material. The foreign material filtered while passing through the foreign matter collector 60 is disposed in the bag and disposed of in the middle.

If the strength of the construction waste is large, if the weight body 80 is turned away from the shaft 36, the fracture impact force of the rollers 31 and 32 increases, but if the rollers 31 and 32 are overloaded, The handle 76 is turned to increase the height of the upper roller 31. In the latter case the material from the last sorter 53 can be circulated back to the hopper 10. The instantaneous overload of the rollers 31 and 32 raises the upper roller 31 but is properly cushioned by the structure which is supported by the spring 73 as shown in FIG.

According to the configuration and operation of the present invention described above, it is possible to continuously produce materials required by particle size while filtering foreign materials such as metals and plastics by simply inputting construction wastes that have undergone simple classification.
