Description

[0001] Crusher for marine garbage and construction waste [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction and marine garbage grinding apparatus, and more particularly, to a construction and marine garbage grinding apparatus and a marine garbage grinding apparatus that effectively reduce the volume of garbage generated in construction and sea- To a grinding apparatus.

In general, various types of industrial waste are emitted in the fields of construction, marine, and agriculture.

Generally, the term "construction waste" refers to soil, sand, gravel, earth or sand mixed with waste, waste materials, etc., concrete, waste wood, asphalt concrete and construction sludge, Are discharged in a mixed state and the treatment thereof is difficult or complicated.

A crusher such as a jaw crusher or hammer crusher is easy to crush concrete or aggregate, but pulverized materials made of vinyl, waste rubber, or synthetic resin are not easy to crush.

On the other hand, today, marine litter that flows from land or is dumped in the sea poses a serious threat to the marine ecosystem. Such marine litter is known to have a vast amount of various kinds of plumes, ranging from plastic, vinyl, waste rubber, and wood pulp to waste net. Since marine litter is difficult to process on its own, it is usually used to collect marine litter and move it to the land. In this process, a crushing device is used to reduce the volume of marine litter and to enable efficient transportation and disposal. Typically, marine litter is immersed in seawater for a long time, so it contains a lot of moisture and is distinguishable from ordinary dry litter. In addition, marine litter has various forms due to the inflow or dumping of sea from the vast area.

Conventional grinding apparatuses do not exhibit the expected performance due to pulverization of marine garbage in the same manner as conventional garbage treatment regardless of the shape and properties of the above-mentioned marine garbage.

As described above, the crusher or crusher has a single cutting structure applied to each of construction, marine and agricultural fields. Thus, the object to be crushed or crushed is limited, and the application efficiency is low.

However, the pulling brush 46 is not limited to such a configuration, . Further, although not shown in the drawing, the pull brush 46 may be installed at an angle to be inclined at an angle to effectively pull or pull the trash. More preferably, the pull brush 46 may be installed at a position corresponding to the recessed portion 43 formed in the support blade 44. In this case, as described later, nonwoven fabrics containing a seawater or flexible garbage such as cloth or vinyl can be more effectively pulled down or towed.

Although a pair of the upper cutter 41 and the lower cutter 42 are shown in the drawing, at least two pairs of the upper cutter 41 and the lower cutter 42 may be provided in multiple stages as required. In this case, since trimming and crushing are performed in multiple stages, it is possible to finely grind trash more effectively.

The lower cutter 42 and, if necessary, the central shaft 47 for rotating the upper cutter 41 are connected to a separate drive motor (not shown), and this configuration and operation can be performed by a person skilled in the art So that detailed description thereof will be omitted.

In the construction and marine litter grinding apparatus according to the present invention, the trash cut by the first crushing section 30 may be put into the second crushing section 40 for finely finishing and then pulverized again. To this end, an induction plate 60 is installed between the first and second grinding spaces S1 and S2. The induction plate 60 is rotatably installed at one end thereof so as to allow the first and second crushing spaces 30 and 30 to drop the truncated and crushed waste material, S1, and the truncated and ground trash in the first crushing unit 30 can be induced and introduced into the second crushing unit 40. The guide plate 60 is not limited to the above but may be constructed such that the first crushing unit 30 cuts and crushes the trash into the second crushing unit 40, It is to be understood that any configuration may be employed as long as it can be selectively induced to be input.

The operation of the construction and marine litter grinding apparatus according to an embodiment of the present invention will now be described.

Waste collected on land or in the ocean may be automatically or manually introduced into the hopper 12 of the grinding apparatus according to an embodiment of the present invention. At this time, as shown in FIG. 1, the switching member 50 is in a state in which the inlet of the first crushing space S1 is opened while the inlet of the second crushing space S2 is closed.

Therefore, the charged trash is cut and crushed in the first crushing section (30). Specifically, the trash inserted into the space between the first and second disk blades 33 and 34 is pulled into the spacing space between the disk blades 33 and 34 while being pulled by the pulling portions 33a and 34a And can be cut and crushed by the edge blades of the disc blades 33 and 34 engaged with each other in this process. Depending on the type of construction and marine litter input, the pulverized waste having passed through the first crushing section 30 is immediately dropped and discharged or is injected into the second crushing section 40 to be subjected to secondary crushing It is possible.

For example, the garbage is cut into a long rectangular piece by the plurality of first and second disk blades 33 and 34. In this case, the pulverized garbage can be introduced into the second grinding part 40 have. To this end, an induction plate 60 for separating the first and second grinding spaces S1 and S2 is switched in the direction of the arrows so as to close the first grinding space S1 as shown in Fig. 1, Accordingly, the pulverized waste having passed through the first pulverizing unit 30 can be introduced into the second pulverizing unit 40 located in the second pulverizing space S2.

Then, the rectangular trash inserted into the second crushing section 40 drops onto the upper cutter 41 and falls between the support blade 44 and the cutting blade 45. In this state, the waste entering between the rotating cutting blade 45 and the fixed support blade 44 can be cut and crushed between them. Further, if the support blade 44 is not fixed and rotates in the direction opposite to the cutting blade 45, cutting and crushing of the waste can be performed more effectively.

In the above-described process, for example, nonwoven fabrics containing plenty of seawater, or flexible garbage such as cloth or vinyl tend to not fall down on the support blades 44. In this case, the cutting blades 45 Can draw or pull these flexible garbage. In this process, the flexible garbage can be not only cut between the support blade 44 and the cutting blade 45 but also can be torn or cut by the pulling force of the pull brush 46, so that the garbage crushing function can be further improved have.

As described above, when the upper cutter 41 and the lower cutter 42 are provided in a plurality of pairs, the cutting and crushing process as described above is repeated, and the construction and marine litter can be cut out more effectively.

According to another embodiment of the present invention, in the case of long and thin rectangular trash (e.g., synthetic waste pipe, waste hose, waste fabric, waste house vinyl, cord, synthetic resin wire, etc.) Can be directly introduced into the second crushing part (40) without passing through. In this case, the switching member 50 is rotated in the direction of the arrow shown in Fig. 1 to close the inlet to the first crushing space S1, while the inlet to the second crushing space S2 can be opened . Then, the rectangular trash inserted through the hopper 12 flows into the second crushing unit 40, and the same cutting and crushing operation as described above can be performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. There may be even examples.
