Description

Shredding Device {CRUSHING APPARATUS}

The present invention relates to a shredding device, and more particularly to a shredding device capable of shredding waste.

Products made of synthetic resins such as tires, vinyl and plastics, which are widely used in various industries and daily life, including food, are recycled only after use, and most of them are classified as waste and landfilled or incinerated.

However, when the waste is buried, not only the problem of securing the landfill site but also the secondary problem of groundwater contamination occurs due to the landfilled waste. This can lead to a secondary problem of air pollution. Recently, technologies for recycling the waste have been developed.

Among them, in order to recycle the waste rubber of the waste tire, it is necessary to crush the waste rubber using a shredding device, and then use the shredding device to manufacture the shredded waste rubber into fine powder.

By the way, in order to maintain the shape of the tire under the load of the vehicle, generally, a metal material such as beadwire and / or steel cord is inserted into the tire, thereby breaking the waste rubber. There is a hassle to separate the waste rubber and the metal material before using a separate device or the like. For this reason, there is a problem that a high cost and time is administered to recycle the waste rubber.

The present invention provides a shredding device capable of selectively shredding the material to be recycled even in a waste state in which materials to be recycled and materials unnecessary for recycling thereof are mixed.

Here, the waste may be at least one of various wastes from various industrial fields and daily life, such as food waste, waste tires, waste vinyl, waste plastics, and the like, and the present invention is not limited by the type of waste. Hereinafter, the waste tire will be described as an example of the waste.

1 is a view for schematically explaining the configuration of a shredding device according to an embodiment of the present invention. FIG. 2 is a diagram for describing the apparatus main body and the cutout illustrated in FIG. 1 in more detail.

1 and 2, the shredding device 100 according to an embodiment of the present invention includes a device main body 110, the press portion 120 and the cutting portion 140. In addition, the shredding device 100 according to an embodiment of the present invention may further include a discharge unit 150, in addition may further include a waste entrance door (160).

The device body 110 may be formed in a substantially cylindrical shape to accommodate the input waste, for example, waste tires, the waste body door opening and closing for the input of the waste tire on one side of the device body 110. 160 may be provided. The waste tire may be added to the apparatus main body 110 in a state in which waste rubber to be recycled and materials unnecessary for recycling the waste rubber, that is, metal materials such as bead wires and / or steel cords are mixed. In addition, the waste tire may be added to the apparatus body 110 without undergoing a separate mechanical or chemical processing process, but is not limited thereto. For example, for ease of crushing the waste rubber, the waste tire is immersed in an aromatic hydrocarbon solvent having excellent swelling property, for example, for 4 to 48 hours, and then the device body part 110 in a wet waste tire state. ), And may be added after various processes. Here, the aromatic hydrocarbon solvent is not particularly limited, but for example, toluene, xylene, benzene, or the like may be used alone, or two or more thereof may be used in combination.

Since the size of the apparatus main body 110 may be variously changed according to the required conditions and design environment, the present invention is not limited thereto. The device body 110 may be formed of a rigid material, for example, a metal material, but the present invention is not limited thereto.

The device main body 110 may have a first through hole 112 formed therein. The first through hole 112 serves as a passage through which waste rubber crushed by the press unit 120 may be discharged to the outside of the apparatus main unit 110, for example, the discharge unit 150.

The first through hole 112 may be formed in a stripe shape in one direction, for example, a vertical or horizontal direction, but the present invention is not limited thereto. For example, the first through hole 112 may be formed along a spiral direction, and the shape may have a curvature such as a circle or an ellipse, and may be variously changed depending on the required conditions and design environment. .

The width W of the first through hole 112 is not particularly limited, but may be, for example, 1 to 20 mm. When the width W of the first through hole 112 is less than 1 mm, the pressure for crushing the waste rubber may increase rapidly. If the width W exceeds 20 mm, the waste rubber may not be finely crushed.

The press unit 120 may be installed inside the apparatus body unit 110. The press unit 120 may be installed to be forward and backward by the forward and backward movement of the piston 122 connected to the hydraulic cylinder (not shown), and the waste rubber by pressing the waste rubber by the forward movement Can be broken.

Specifically, when the press unit 120 is moved forward, the waste rubber is compressed and at the same time receives a force to expand in the plane direction perpendicular to the advance direction of the press unit 120. At this time, when the waste rubber is compressed above a predetermined threshold point, the waste rubber is separated from the metal material and crushed little by little. As described above, the waste rubber is discharged to the discharge unit 150 through the first through hole 112. Can be.

As such, the waste rubber of the waste tire is crushed and discharged from the apparatus main body 110, while the metal material of the waste tire may remain in the apparatus main body 110 without being crushed. This residual metal material may be simply collected from the apparatus body part by opening the waste door 160 after the shredding process is finished.

As described above, when the waste rubber is compressed, since the waste rubber and the metal material are separated and the waste rubber is simultaneously crushed, the metal material may be separated using a separate device or the like before the process of crushing the waste rubber. There is no need to remove it.

The press unit 120 may be installed to enable rotational movement as well as forward and backward movements. As such, when the press unit 120 rotates simultaneously with the forward movement, since the waste tires adjacent to each other among the waste tires are subjected to frictional force by the rotation of the press unit 120, the waste rubber is more easily broken by the frictional force. Can be.

FIG. 3 is a view schematically illustrating a shape in which waste tires are seated on the press unit illustrated in FIG. 1.

Referring to FIGS. 1 and 3, the press unit 120 may be formed in an upper conical shape, but the present invention is not limited thereto. For example, the press unit 120 may be formed in a flat shape or a pyramid shape, or various other shapes. On the press part 120, a waste tire 170 introduced into the apparatus main body 110 may be seated.

4 is a view for explaining the press unit shown in FIG. 1 in more detail.

Referring to FIG. 4, the upper surface of the press unit 120 may include first and second mirror surfaces 124 and 126 formed in a radial shape. The first and second mirror surfaces 124 and 126 may have some or all faces, or some or all of them may have curved surfaces.

The first and second mirror surfaces 124 and 126 are formed to meet each other, that is, to share at least one line, thereby forming crests and troughs, thereby apparently forming an upper surface of the press part 120. The corrugated shape may be formed, but the present invention is not limited thereto. For example, the first and second mirror surfaces 124 and 126 may be formed not to meet each other, and may be variously changed according to required conditions and design environments.

Second and third through holes 128 and 130 may be formed in the first and second mirror surfaces 124 and 126. Each of the second and third through holes 128 and 130 may serve as a passage through which some of the crushed waste rubber may be discharged to a crushing device (not shown) for finely crushing the crushed waste rubber. Can be performed. That is, most of the crushed waste rubber is discharged to the discharge part 150 through the first through hole 112, but a part of the waste rubber is crushed through the second and third through holes 128 and 130, respectively. Can be discharged. At least one of the second and third through holes 128 and 130, for example, the third through hole 130 may be formed along the circumferential direction of the press unit 120. The second and third through holes 128 and 130 and the grinding device may be connected to each other by using the first discharge pipe 132 shown in FIG. 1 to facilitate discharge of the crushed waste rubber. Since the structure can be variously changed according to the required conditions and the design environment, the present invention is not limited thereto. Here, the number and diameter of each of the second and third through holes 128 and 130 and the first discharge pipe 132 may be variously changed according to a required condition and a design environment. It is not limited.

5 is a view for explaining in more detail the through-hole formed in the press unit shown in FIG.

Referring to FIG. 5, the first and second mirror surfaces 124 and 126 may include the second and third through holes to induce the inflow of waste rubber crushed into the second and third through holes 128 and 130, respectively. It may be formed in a funnel shape in the vicinity of (128, 130). That is, the first and second mirror surfaces 124 and 126 may be formed to be inclined upward within a predetermined distance with respect to each of the second and third through holes 128 and 130, respectively. However, the present invention is not limited to this because it can be varied in various ways depending on the required conditions and design environment.

Again, referring to FIGS. 1 and 2, the cutting part 140 is installed to intersect the first through hole 112, and when the crushed waste rubber is discharged through the first through hole 112. The crushed waste rubber can be cut finely. That is, when the crushed waste rubber is discharged through the first through hole 112, the crushed waste rubber becomes a structure that is caught by the cutting unit 140, and thus can be naturally cut finely. To this end, the cutting unit 140 may be formed as sharp as possible, such as a metal material having good rigidity, but the present invention is not limited thereto.

The cutting unit 140 may be installed inside or outside the device body 110, but may be installed outside the device body 110. For example, the cutting part 140 may be formed in a ring shape to surround the outer circumferential surface of the apparatus main body part 110.

The interval I between the cut portions 140 is not particularly limited, but may be, for example, 1 to 50 mm. When the gap I between the cut portions 140 is less than 1 mm, the pressure for crushing the waste rubber may increase rapidly. If the gap I exceeds 50 mm, the waste rubber may not be finely crushed.

The discharge unit 150 may be installed outside the device body 110, for example, in a structure surrounding the device body 110. The discharge unit 150 may accommodate the crushed waste rubber discharged through the first through hole 112, and discharge the received waste rubber to the grinding device via the second discharge pipe 152. have. Here, the connection structure of the discharge unit 150 and the grinding device may be variously changed according to the required conditions and design environment, thereby the present invention is not limited thereto.

As described above, according to one embodiment of the present invention, when the waste tire 170 is put into the apparatus main body portion 110, and the waste tire 170 is compressed using the press unit 120, The crushed waste rubber may be discharged to the discharge unit 150 through the first through hole 112 formed in the main body 110. In this case, the crushed waste rubber may be finely cut by the cutting unit 140, and the cut waste rubber may be discharged to the grinding device.

In addition, when the shredding process is performed using the shredding apparatus 100 according to an embodiment of the present invention, since the waste rubber and the metal material are separated and the waste rubber is shredded, a separate device before shredding the waste rubber It is not necessary to remove the metal material using the back and the like. For this reason, the recycling process of the waste tire can be simplified, and the cost and time can be shortened.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can realize that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. I can understand that.
