Description

Crusher {A crusher}

The present invention relates to a crusher, and more particularly to a crusher including a crushed bundle and a hammer mill including a hook having a different length.

Due to the development of the industry, workplace wastes are combustible wastes such as paper, wood, rubber and leather, animal and vegetable residues, sludge, and slag, combustibles and dusts, building wastes, metals and super magnetics, waste lime And non-combustible wastes such as gypsum and so on, and waste disposal has been relied on landfilling and incineration, but due to the problem of landfill securing, environmental adverse effects of incineration, and the need for recycling of resources, Korea's waste management system is in the middle of final disposal. The situation is rapidly changing to treatment and recycling.

As one of such recycling technologies, research is being actively conducted to prepare a flammable waste solid fuel (RDF) or a waste plastic fuel (RPF) that can produce waste as a solid raw material. In this regard, in order to manufacture the combustible waste solid fuel and the like, the wastes generated in everyday life and industrial sites are crushed to make the properties of the waste fine and uniform, improving porosity, increasing specific surface area, improving dryness and combustibility, and sorting. It should be easy.

There are four methods of crushing wastes: compression, impact, shearing, and crushing. Among these methods, the method of crushing by compacting action is to insert crushed material on two sides and compress crushing, which is suitable for hard and hard materials, wearable, low viscosity, and uniform particle size after crushing. to be.

In order to produce such combustible wastes, a compression shredder is used, but a conventional compression shredder has to be equipped with a waste push device for pushing the waste into the shredder, and the bearing part for the rotation of the shredder is shredded. It is installed inside the seal, which causes problems due to foreign matter inflow, and waste is not caught in the crushing bundle, so it is rotated together to reduce the crushing efficiency.The two crushing bundles each have an integrated bearing, spindle, cutter and crushing chamber casing. There is a problem that takes a lot of time and manpower during maintenance.

The present invention is to solve the conventional problems, one object of the present invention is that the input waste is easily attracted to the crushing rolls without a push device can be effectively crushed, to remove the waste caught in the crushing bunch and easy to maintain To provide one shredder.

One aspect of the present invention, a waste hopper; A crushing chamber installed under the hopper; A crushing bundle having two main shafts installed at regular intervals through the crushing chamber and a cutter installed on the main shaft; A drive motor and a speed reducer for driving the crushing unit; A hammer mill installed under the crushed wad to remove waste caught in the crushed wad; And it relates to a crusher comprising a hammer mill drive motor for rotating the hammer mill.

Another aspect of the invention relates to an apparatus for producing combustible waste solid fuel comprising the shredder.

The crusher according to the present invention can be easily drawn into the crushing rolls without a push device to crush waste efficiently, install a bearing for rotating the crushing bunch out of the crushing chamber and improve the durability of the bearing through sealing with the casing It is possible to increase the crushing efficiency by installing a hammer mill rotating under the crushing lump in the crushing chamber to increase the crushing efficiency, and to make it easy to separate the crushing bundle, casing and bearing parts. This saves time and manpower for maintenance.

Crusher according to an embodiment of the present invention is characterized in that it comprises a hammer mill is installed in the lower crushed wad to remove the waste caught in the crushed wad.

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

1 and 2, the crusher 100 according to an embodiment of the present invention is a hopper 10, crushing chamber 20, crushed bundle 30, the drive motor for driving the crushed bundle And a reducer 50, a hammer mill 60, and a hammer mill driving motor 70 for rotating the hammer mill.

First, when the waste is introduced into the hopper 10 and guided to the crushing chamber 20, the power by the driving motor 40 is transmitted to the reducer 50 to rotate the crushed bundle 30 at an appropriate rotational speed. Crush. The hammer mill 60 is rotated by a separate drive motor 70 under the crushed lump to remove waste from the crushed lump.

The hopper 10 may be installed to be inclined to guide waste to the crushing chamber 20.

The crushed wad 30 has two main shafts 31 installed at regular intervals through the crushing chamber 20 and cutters 32 installed on the main shafts 31.

1 and 2, two spindles 31 are arranged side by side at predetermined intervals, and the cutter 32 is installed on the spindle 31 to form a crushed bundle 30. The two crushed wads 30 are installed parallel to each other at a predetermined interval to pass through the waste to be crushed.

3 is a front view of a cutter 32 that may be used in a shredder according to one embodiment of the present invention, and FIG. 4 is another type of cutter 32 that may be used in a shredder according to one embodiment of the present invention. 5 is a schematic diagram showing the crushed wad 30 in which the cutter 32 according to FIG. 3 is assembled to the main shaft 31.

Referring to FIG. 3, the cutter 32 includes hooks 321 and 322 and a spacer 33, and the hooks 321 introduce the waste introduced into the hopper 10 into the crushed bundle. ) And a second hook 322 for crushing and crushing the incoming waste. The cutter may have one to three first hooks and five to ten second hooks, and preferably three first hooks and six second hooks.

The first hook 321 is 2 to 4 times longer than the second hook 322.

Referring to FIG. 4, the cutter includes hooks 321, 322, and 323 and a spacer 33, and the first hook 321 for introducing the waste introduced into the hopper 10 into the crushed bundle by the hook. And a second hook 322 for crushing the incoming waste and a third hook 323 for crushing. The length of the first hook, the second hook, and the third hook may be reduced.

The first hook 321 may be 2 to 4 times longer than the third hook 322. Preferably, the first hook may have a size about 2 times larger than that of the second hook and about 3 times larger than the third hook. However, the size of the first hook may be adjusted in consideration of the properties of the crushed material and the particle size after crushing.

In the case where the third hook 323 is added, the third hook is preferably installed between the second hooks. 4, three third hooks were used.

Referring to FIG. 5, the first hook 321 is designed to be relatively longer than the second hook 322 so that the waste introduced into the hopper 10 may be easily pulled out and introduced into the crushed wad.

In the two crushed bundles 30, the hook of the cutter 32 assembled on one of the two main shafts and the spacer 33 of the other main shaft are engaged to crush the waste. In particular, the second hook 322 serves to crush the waste by using a compressive force.

Figure 6 is a schematic diagram of a hammer mill used in the shredder of one embodiment of the present invention.

Referring to FIG. 6, the hammer mill 60 includes a main shaft 61, a plurality of support plates 62 installed on the main shaft, and a hammer mill blade 64 fixed on an auxiliary shaft 63 passing through the support plate. It may include.
