Description

[0001] GLASS CRUSHER [0002]

The present invention relates to an apparatus for crushing glass. More particularly, the present invention relates to a glass crusher having structurally superior abrasion resistance.

Waste glass is recycled to the substrate glass through crushing and melting processes. Prior to melting the glass cullet, a glass crusher is used to crush the glass to a required size.

FIG. 1 and FIG. 2 are views schematically showing a conventional glass crusher.

1 includes a shaft 10, an end disk 20, a center disk 30, a support bar 40, and an impact hammer 50. [

The glass is supplied from the top to the crusher. The supplied glass drops downward by gravity. The falling glass is crushed to a small size by impact of the impact hammer 50. The shredded glass cullet falls down and is collected. The collected glass cullet is melted and recycled to the substrate glass.

The shaft 10 rotates about its rotation axis. The end disk 20 and the center disk 30 are fixed to the shaft 10 and are rotated together with the shaft 10. The center disc 30 is positioned between the both end discs 20.

The end disk 20 and the center disk 30 have a plurality of through holes at corresponding positions. The supporting bar 40 is fixed through the corresponding through holes of the end disk 20 and the center disk 30. [ In Fig. 1, two end disks 20, three center discs 30 and three support bars 40 are shown.

Each support bar 40 is provided with an impact hammer 50. The impact hammer 50 is pivotally mounted on the support bar 40 as a rotation center. FIG. 1 shows an embodiment in which four support bars 40 are provided with four impact hammers 50. Therefore, a total of twelve impact hammer 50 are installed on the three support bars 40.

Further, the glass crusher may further include an impact block 60 as shown in Fig. When the impact hammer 50 strikes the glass falling from the upper chute, primary crushing is performed, and a part of the struck glass collides with the impact block 60 to perform secondary crushing.

FIG. 3 is a view showing wear of the shaft 10 / disk assembly of the glass shredding apparatus of FIG. 1, and FIG. 4 is a view showing wear of the impact hammer 50 of the glass shredding apparatus of FIG.

In the above-described conventional glass crushing apparatus, the center disk 30 is located in the work area where the glass is supplied and crushed. The center disk 30 is continuously worn by the glass.

As shown in the figure, unlike the initial state (left side), the outer circumferential portion of the center disk 30 is considerably worn after a certain degree of use (right side).

The center disc 30 serves to maintain the gap between the impact hammers 50. [ When the abrasion of the center disk 30 is abandoned by abandoning the wear of the center disk 30, erosion occurs to the penetration hole portion of the center disk 30. In this case, the center disk 30 can no longer perform the role of maintaining the gap between the impact hammers 50. [0053] At this time, the impact hammer 50 is allowed to move in the axial direction of the shaft 10. As a result, the wear of the center disk 30 is further accelerated.

Further, when the erosion of the center disk 30 is further increased, the impact hammers 50 are collided with each other. This further increases the wear rate of the impact hammer 50 and causes the impact noise. In addition, in a severe case, the impact hammer 50 may be disengaged with the cutting of the support bar 40. [

As described above, the above-described conventional glass crushing apparatus has a problem in that it is structurally weak in abrasion resistance and has a short device life.

Metal powder is incorporated into the glass cullet by the amount lost by abrasion. This is to lower the purity of the regenerated glass.

After use, the wear components must be replaced. This is accompanied by a periodic replacement cost. In addition, since the operation must be interrupted during the replacement, the operation rate of the equipment is lowered.

Meanwhile, the conventional crusher has a problem that the end disk 20, the center disk 30, and the impact hammer 50 are susceptible to abrasion.

Disclosure of Invention Technical Problem [8] The present invention has been made in order to solve the problems of the conventional crushing apparatus described above, and it is an object of the present invention to provide a crushing apparatus having an excellent wear resistance.

The present invention also provides a crushing apparatus having excellent abrasion resistance as a material.

In order to achieve the above object, Two end parts coupled to the shaft, the two end parts defining a working area to be supplied with the glass; And at least one impact hammer disposed between the end parts, wherein the shaft is formed to extend through a central rotation axis of the two end parts.

The at least one impact hammer may be pivotably coupled to the shaft between the two end parts.

Each impact hammer may include a bag and a head. One end of the bag is coupled to the shaft, and the head can be formed at the other end of the bag.

According to the above-described constitution, the present invention has an effect of providing a glass crushing apparatus having excellent abrasion resistance.

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

5 is an exploded view schematically showing a glass crusher 400 according to an embodiment of the present invention.

The glass is supplied from the upper portion to the crusher 400. The supplied glass drops downward by gravity. The falling glass is crushed to a small size by impact of the impact hammer 500. The shredded glass cullet falls down and is collected. The collected glass cullet can be regenerated as a substrate glass, for example, through a melting process.

The glass shredding apparatus 400 of the present invention includes a shaft 100, two end parts 200, and at least one impact hammer 500. In the embodiment of FIG. 5, the shaft 100 is formed to extend between the center rotational axes of the two end parts 200. Also, in the embodiment of FIG. 5, at least one impact hammer 500 rotates about the central axis of rotation of the two end parts 200.

The shaft 100 rotates about the center axis of the two end parts. The shaft 100 is driven by a driving device (not shown). The shaft 100 includes a shaft body 110 and a protrusion 120. The shaft body 110 is a body extending in the axial direction of the shaft 100. The protrusion 120 is protruded outward from the shaft body 110. Since the protrusion 120 is a component to which the impact hammer 500 is to be coupled, it is formed in a number corresponding to the number of the impact hammer 500. FIG. 5 shows an embodiment in which four protrusions 120 are formed. However, in other embodiments, more or less than four protrusions may be used.

5 shows a structure in which the protrusion 120 includes the first protrusion 121, the second protrusion 125, and the fixture 123. As shown in FIG. The first protrusion 121 may be integrally formed with the shaft body 110 and may protrude outward from the shaft body 110. The first protrusion 121 and the second protrusion 125 have insertion holes 121a and 125a at corresponding positions. The fixture 123 functions to fix the second protrusion 125 to the first protrusion 121 and to fix the insertion hole 121a of the corresponding first protrusion 121 and the insertion hole 121a of the second protrusion 125, (125a). Each second projection 125 has two pivot pins 125b. The two pivot pins 125b protrude from both sides of the second projection 125 in the axial direction. 5, the first protrusions 121, the second protrusions 125, and the fixtures 123 are assembled together as separate entities, but this is merely an example. For example, protrusions of a single body are possible, and various other modifications are possible. It is also possible to replace the protrusion 120 of the embodiment of Fig. 5 with a recess in the shaft body 110 and to fit the impact hammer 500 in the recess. That is, as long as the impact hammer 500 can be pivotably coupled to the shaft 100, those skilled in the art can easily carry out the modification without difficulty.

The two end parts 200 are fixedly coupled to the shaft 100 so that the two end parts 200 are rotated together as the shaft 100 is rotated. Also, the two end parts 200 are spaced apart from one another such that the area between the two end parts 200 is the work area. The work area is the area where the glass is supplied and the shredding operation is performed. Typically, the glass is dropped and supplied at the top of the shredding apparatus 400, but the present invention is not limited thereto. The end part 200 typically has a disk shape, but the present invention is not limited thereto.

The impact hammer 500 is positioned between the end parts 200, that is, the work area. This means that the impact hammer 500 is not located outside the end parts 200 in the axial direction. Therefore, the glass is not broken outside the both end parts 200.

In contrast to a conventional grinding device, the grinding device 400 of FIG. 5 does not have a center disk positioned between both end disks. Therefore, it is possible to solve the problem caused by the center disk wear.

5, the support bar 40 of the conventional shredding apparatus is removed, and the impact hammer 500 is directly coupled to the shaft 100 instead. The impact hammer 500 is rotatably coupled to the shaft 100. The impact hammer 500 is coupled to the shaft 100 such that the rotary shaft of each impact hammer 500 is positioned away from the rotary shaft of the shaft 100 in the radial direction of the shaft 100.

The impact hammer 500 includes a head 510 and a bag 520. One end of the bag 520 is rotatably coupled to the shaft 100. The head 510 is formed at the other end of the bag 520. The bag 520 has two branches at one end thereof. In Fig. 5, the protrusion 120 is sandwiched between two branches of the impact hammer 500. Therefore, it is constrained that the impact hammer 500 moves in the axial direction of the shaft 100. [ As a result, the impact hammer 500 is prevented from colliding with each other.

Each impact hammer 500 is rotatably coupled to each protrusion 120. 5, the branched end has the shape of the hook 520a and the pivot pin 125b of each protrusion 120 is fitted in the hook 520a so that the bag 520 is rotatably mounted on the protrusion 120 It is to be understood that the present invention is not limited thereto. For example, the shape of a pin or a hook is not essential. It is also possible that a hook is formed in the protrusion 120 and a pin is formed in the bag 520. Also, a single hook and a single pivot pin may be used instead of the two branched hooks 520a.

The shredding apparatus 400 of the present invention includes at least one impact hammer row. Impact hammers belonging to a specific row may be spaced apart from each other along the axial direction of the shaft 100. In FIG. 5, two rows of impact hammer 500 are shown.

In addition, the shredding apparatus 400 of the present invention includes at least one impact hammer column. Impact hammers 500 belonging to a specific column may be spaced apart from each other along the circumferential direction of the shaft 100. In FIG. 5, two rows of impact hammers 500 are shown.

The distance between the impact hammers 500 along the axial direction of the shaft 100 should be minimized. The gap between the impact hammers 500 is widened, and wear of the impact hammer 500 can be promoted.

5 illustrates an impact hammer 500 arranged in a row along rows and columns, but the present invention is not limited thereto. For example, when the impact hammer 500 is arranged only along the rows (i.e., when the impact hammer 500 is arranged out of alignment without being linearly arranged), the impact hammer 500 is arranged only along the row A case where the hammer 500 is arranged shifted without forming a linear row) is also possible. Further, it is possible that the impact hammer 500 is arranged without forming rows and columns.

The design of the four-column imprint hammer of Figs. 1 and 2 was modified to be a two-column impact hammer 500 in the embodiment of Fig. Therefore, the edge of the impact hammer 500, which is the starting point of the abrasion, can be reduced, thereby improving the abrasion resistance of the impact hammer 500. The abrasion resistance can be greatly improved by such a simple structural change, which is a feature of the present invention. In the same principle, one row of impact hammer 500 may be more preferable in terms of abrasion resistance than two columns. Further, the edge portions of the impact hammer 500 are subjected to rounding treatment to further improve wear resistance. As a result, intensive wear of the corner portion can be prevented.

In order to further enhance the wear resistance, the two end parts 200 and the impact hammer 500 may be made of, for example, carbon steel in which tungsten carbide is cladded.

When such a material is used in combination with the structure improvement (improved from the structure of FIG. 1 to the structure of FIG. 5) according to the present invention, the lifetime is increased from about 5000 tons to at least about 11488 tons Can be improved.

The improvement of the abrasion resistance provided by the glass crushing apparatus according to the embodiment can greatly reduce the amount of metal powder incorporated into the glass cullet. Thus, a regenerated glass of excellent quality can be obtained. In addition, the replacement cost can be reduced, and the facility operation rate can be greatly improved.
