Description

Can Crushers

The present invention relates to a crusher, and more particularly, to a can crusher which can classify each of the aluminum and / or steel cans finely by two pairs of crushing gears.

Aluminum or steel cans used for beverage cans and similar uses are collected and sorted for recycling purposes. In this process, the cans are collected within a range that does not deviate significantly from their original shape until processing. And classified. In other words, the collector collects aluminum cans and steel cans, sorts them separately, compresses them to a certain size to minimize the volume of the cans, melts them in the blast furnace and recycles them later. However, in the above process, the collector must bear the inconvenience of separately collecting each can, and even in the compression process, a certain volume or less is not only difficult to work with, but also caused to move a large compressed can during transportation. This led to an increase in logistics costs.

In recent years, various types of shredders for separating and collecting aluminum or steel cans are actively studied to overcome the above problems.

A typical example of such a shredder is to shred a can into which it is introduced by a shredder made of steel and then collect the pieces. However, in this example, in addition to the fundamental problem that the aluminum can and the steel can must be separated separately at the time of initial collection, cans, which are broken by the strong turning force when the shredder breaks the can, can damage the inside of the apparatus and are irregular. The crushed cans have a problem of increasing packaging volume during packaging for transportation. In addition, when an aluminum can and a steel can are mixed into the apparatus due to a mistake of a user, the crushed can requires a separate process for classifying aluminum and steel. May lose the purity of the recycled product and reduce the quality of the recycled product.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a small capacity can breaker capable of finely and uniformly crushing aluminum and / or steel cans by two pairs of crushing gears.

It is another object of the present invention to automatically sort and collect aluminum and steel cans mixed and crushed by the crushing gears in the apparatus.

In order to achieve the above object, a crusher according to the present invention includes a main body having a can inlet and an outlet, a first crusher for primary crushing of aluminum and / or steel cans introduced through the can inlet, and the first crusher. The second shredding unit installed at the lower end and second shredding the pieces of aluminum and / or steel cans first shredded through the first shredding part, and the can pieces shredded through the first and second shredding parts according to the respective types. And a sorting unit for sorting, a storage unit for storing sorted can pieces formed at a lower end of the sorting unit, and a driving unit for individually or integrally driving the first crushing unit, the second crushing unit, and the sorting unit.

Each of the first and second shredding parts is composed of a pair of shredding gears, and closes and shreds aluminum and / or steel cans that are input by the interlocking rotational motion of the shredding gears, thereby enabling miniaturization and uniformity.

The sorter described above sorts aluminum and steel cans from mixed crushed can pieces using magnetic force.

The driving unit may be formed on the rear side of the apparatus to separately drive the first crushing unit, the second crushing unit and the sorting unit, and may be integrally driven using a power transmission means such as a V-belt.

1 is a front view of a can breaker according to the present invention.

2 is a side view of a can breaker according to the present invention.

3 is a side view of a crushing gear according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 is a front view of a can crusher according to the present invention, Figure 2 is a side view, the crusher according to the invention a main body 10 having a can inlet 13 and an outlet (not shown), and the can inlet 13 The first crushing unit 15 for primary crushing the aluminum and / or steel cans introduced through the) and the first crushing unit 15 is installed at the lower end of the first crushing unit 15 A second shredder 17 for secondly shredding the can pieces, a sorter 19 for sorting the can pieces shredded through the first and second shredders 15 and 17 according to their respective types, and The storage unit 19 is formed at the bottom of the sorter 19 and stores the sorted can pieces, and the first crusher 15, the second crusher 17 and the drive unit for driving the sorter 19. . At this time, the first crushing unit 15 includes a pair of crushing gears 15a and 15b, and the second crushing unit 17 includes another pair of crushing gears 17a and 17b. In addition, the sorter 19 includes a pair of rollers 19a and 19b driven by a drive motor (not shown) and a belt 19c driven by the driving force of the rollers 19a and 19b.

At the lower end of the main body 10, a wheel 25 is attached to free the movement of the device. The wheel 25 is detachable and may be used after the wheel 25 is removed.

In the crusher having the above structure, first, the aluminum and / or steel cans introduced through the can inlet 13 are crushers of the first crusher 15 rotated by the rotational movement of the drive motor built into the main body 10. Primary crushing is performed while passing through the fish 15a and 15b. Subsequently, the can pieces crushed through the first crushing unit 15 are moved to the crushing gears 17a and 17b of the second crushing unit 17 along the inner wall of the device indicated by the dotted line in FIG. The crushing gears 17a and 17b are crushed more precisely. In this case, the driving motor on the rear of the device may drive the first crushing gears 15a and 15b and the second crushing gears 17a and 17b separately or integrally, respectively. The canned pieces crushed through the above process are collected in the sorter 19 at the lower part of the apparatus, and are stored in the storage unit 23 via the belt 19c driven by the rotational force of the pair of rollers 19a and 19b which rotate clockwise. To fall. At this time, the belt 19, although not shown in the drawing, has a through hole to separate foreign matter other than the crushed can pieces, for example, beverage dregs, from the pure can pieces. Reference numeral 18 denotes a large magnet mounted inside the roller 19b. The magnet 18 exerts a magnetic force to the area A of the drawing so that the steel can pieces are attracted to the storage container 23a. At this time, it is also possible to attach a device for generating a magnetic force. On the other hand, the aluminum can crushed through the first and second shredding parts 15 and 17 falls vertically into the storage container 23b while passing through the end of the roller 19b without being affected by the magnet 18.

3 is a view showing the shape of the crushing gear (15a, 15b, 17a, 17b) according to a preferred embodiment of the present invention, each crushing gear is the thickness S1, the distance between neighboring teeth S2, and the gear width S1 = 8 mm, S2 = 8.5 mm, S3 = 150 mm is preferable. Although not shown in the drawings, the distance between the drive shafts of each adjacent gear is preferably 240 mm. In addition, each crushing gear can be applied to the present invention irrespective of any kind as long as the crushing gear has a hardness enough to crush the steel can.

According to the above process, the aluminum and steel cans are easily shredded, sorted and collected in a mixed state, so that they can be installed in a narrow place, for example, near a garbage bin in a park, in a large shopping mall and in an apartment collection facility, to maximize efficiency. can do. Of course, it is also possible to increase the capacity of the device and use it in large factories. Collectors can arrange and transport shredded can pieces in a sorted state, thereby maximizing packaging efficiency, lowering logistics costs, and minimizing time and cost loss for reclassification.

According to the can crusher of the present invention, uniform and fine can pieces can be obtained by crushing aluminum and / or steel cans by engaging rotational movements of the crushing gears, thereby maximizing packaging efficiency and reducing transportation costs. .

In addition, by automatically sorting the mixed can pieces in the device, no separate sorting process is required.
