The present invention relates to a waste shredding device, and more particularly, to shred waste such as waste synthetic resin or wood waste, to recycle and to control the size of particles during the second shredding after the first shredding. The present invention relates to a waste shredding device that maximizes its utility in recycling fuel such as fuel.

In general, waste synthetic resins or wood wastes that are classified and discharged as domestic or industrial wastes are finely crushed by a crusher and recycled as fuel. At this time, the smaller and larger the shredded size, the higher the use value.

Here, the waste synthetic resin is a general term for synthetic resin waste generated at a living or industrial site in which it is disposed of due to its use, and wood waste is a timber (eg, lumber, plywood, etc.) included in the waste at the construction site or during road construction. It is a concept that collectively refers to wood (wood pallets, wooden wire rolls, etc.) which are generated by-products of wood, tree roots and various production activities.

These wastes were collected and finally crushed to a certain size through a crusher as shown in FIG. 1, and then finally crushed to a size necessary for recycling.

By the way, the conventional shredder is only collected in the primary and secondary shredding rolls (20, 30) equipped with a shredding blade as the waste (12) loaded into the hopper 10 is moved to the lower portion of the hopper (10) Since it was a simple crushed form, the particles of the crushed material was large and uneven (not uniform), so even if moved to the subsequent process through the conveyor belt 40, there was a disadvantage that the quality is very poor to use as fuel.

In addition, even if you want to adjust the particle size of the crushed particles as needed, the function of adjusting the particle size arbitrarily has not implemented a lot of inconvenience.

The present invention was devised to solve this problem in view of the above-described problems of the prior art, and evenly crushes the particle size of the crushed crushed waste when crushing waste, particularly waste plastic or wood waste for recycling as fuel. Its main purpose is to provide a waste shredding device that can be used as well as freely varying the particle size of the shredded material as needed, thereby increasing recyclability and maximizing the utility as a fuel.

In order to achieve the above technical problem, the present invention provides a hopper, a primary crushing roll disposed above the inner side thereof, a secondary crushing roll installed below the secondary crushing roll, and a lower portion of the secondary crushing roll. A waste shredding device comprising a conveyor belt; A damper plate disposed at intervals with the same radius of curvature on the side of the hopper inside the secondary crushing roll; The waste crusher is fixed to be rotated in place in the back of the damper plate and the waste crusher comprising a spacer installed forward and backward through the fixed plate fixed to the wall surface of the hopper or the hopper separately. There is a characteristic.

In this case, a plurality of protrusions may be formed on the inner surface of the damper plate, and the gap adjuster may be formed as a screw shaft-type fixing bar provided with a bolt head at a rear end thereof.

In addition, the spacer may be composed of a rack disposed through the wall surface or the fixing plate of the hopper, a pinion installed on a path through which the rack flows to engage the rack, and a motor for driving the pinion.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention in more detail.

Damper, which is a main component of the waste shredding device according to the present invention, for example, a shredder for recycling construction waste, that is, jaw crusher, Gyratory Crusher, Cone Crusher, It can be applied to a double roll crusher, an impact crusher, and the like.

2 and 3, the waste shredding device according to the present invention, the hopper 100 for receiving the waste 120, and is installed on the upper side in the hopper 100 and the waste blades for shredding (120) The first crushing roll 200 is rotated at a low speed with a 210, and the primary crushing roll 200 is installed in the lower side in the hopper 100 at intervals in the vertical direction and the primary crushed waste 120 again Secondary crushing roll 300 is rotated at high speed with a blade 310 for crushing and a conveyor belt 400 for storing the crushed crushed matter disposed in the lower end of the hopper 100 and then transferred to a subsequent process, and And a damper 500 installed through the outer wall of the hopper 100 corresponding to the secondary crushing roll 300 to maintain a predetermined interval with the secondary crushing roll 300.

At this time, the rest of the configuration except the damper 500, that is, the hopper 100, the primary crushing roll 200, the secondary crushing roll 300 and the conveyor belt 400 is configured to the same or similar to the conventional.

That is, the main characteristic configuration of the present invention is that the damper 500, the damper 500 is installed in the damper plate 510, the back of the damper plate 510, as shown in FIG. It is composed of a spacer (R).

Here, the damper plate 510 is formed with a radius of curvature corresponding to the radius of curvature of the secondary crushing roll 300, a plurality of protrusions on the inner surface, that is, the surface facing the secondary crushing roll 300 520 is protruded.

At this time, the protrusion 520 assists in crushing the first crushed crushed matter more finely, that is, the particle size is smaller and uniform by interaction with the blade 310 provided in the secondary crushing roll (300). It is provided to perform a function.

The gap adjuster R includes a fixing plate 530 and a fixing bar 540 that is fixed to the rear surface of the damper plate 510 by penetrating the fixing plate 530.

Here, the fixing plate 530 is a plate-like member so that the screw thread is formed on the inner surface of the hole through which the fixing bar 540 passes, and the fixing bar 540 has a screw shaft shape. It is preferable that the fixing bar 540 is configured to move forward or backward with respect to the fixing plate 530 by tightening or releasing).

Of course, the fixing plate 530 may be provided as a separate member, the hopper 100 itself may be processed so that the outer wall surface of the hopper 100 performs the function of the fixing plate 530. .

In addition, the fixing bar 540 may be installed on the rear surface of the damper plate 510 in the horizontal direction as shown, or may be installed on the rear surface of the damper plate 510 in the vertical direction.

In addition, the front end of the fixing bar 540, that is, the portion connected to the damper plate 510 is formed in a spherical shape as shown in the figure so as to be idlely connected and fixed in a ball joint manner. As a result, when the fixed bar 540 is rotated forward and backward, only the fixed bar 540 is rotated, and the damper plate 510 may maintain the current state without rotation.

At this time, the connection relationship between the fixed bar 540 and the damper plate 510 is not limited to the illustrated example, that is, the ball joint method is possible all the known structure that the fixed bar 540 can be rotated idlely. Is a matter of course.

For example, the fixing bar may be formed by protruding the rear place of the damper plate 510 and then forming a 'ㅗ' -shaped groove therein, or by inserting a 'ㅗ' -shaped groove in the rear place of the damper plate 510. It is possible to connect the end of the 540 so that it is not easily separated after being fitted therein, and then configured to be operated idlely through a means such as a washer or bush.

In addition, the fixing bar 540 is provided with a screw shaft-shaped main bar 540 'linked to the rear surface of the damper plate 510, as shown in Figure 4 (a) for smooth operation. The guide bar 550 may be provided at both sides of the main bar 540 ′ to move the damper plate 510 forward and backward easily, and the main bar 540 ′ may be easily moved forward and backward. ) May be designed to be drive controlled by a known drive means such as a motor, and the main bar 540 'is a simple circular bar type instead of a screw shaft type, and the drive is controlled back and forth through the ball and hydraulic cylinders. It can also be designed to do so.

Furthermore, as shown in Fig. 4 (b) by cutting a portion, the pinion 560 driven by a driving means such as a motor is installed on the outer wall surface of the fixed plate 530 or the hopper 100, The square bar is formed by forming a rack on one side of the square bar 540 ″ into which the square bar 540 ″ is inserted into the square hole in which the pinion 560 is installed. 540 ") may be controlled to drive forward and backward.

The working relationship of the present invention made of such a configuration is as follows.

The waste 120 charged into the hopper 100 is first crushed to a large size by a primary crushing roll 200 and a blade 210 installed on an outer surface of the waste crusher driven at about 6 rpm. Will be moved to the lower side of the.

Subsequently, the dropped primary crushed objects are finally crushed by the secondary crushing roll 300 which rotates at a high speed at about 1200 rpm installed below the primary crushing roll 200 and the blade 310 installed on the outer surface thereof. At this time, the primary crushed materials that are moved together while hitting the secondary crushing roll 300 are the outer surfaces of the damper plate 510 and the secondary crushing roll 300 to maintain an appropriate interval with the secondary crushing roll 300. Forced crushing is also caused by the protrusion 520 protruding on the inner surface of the damper plate 510 while being crushed by the blade 310 while being moved through the space between the ends of the blade 310.

Through such a process, the primary crushed materials are uniformly crushed to a size corresponding to a narrow space, that is, a separation distance between the damper plate 510 and the secondary crushing roll 300.

Of course, if necessary between the damper plate 510 and the secondary crushing roll 300 by adjusting the length of the fixing bar 540 for fixing the damper plate 510, that is, the length exposed to the inside of the hopper 100 The spacing can be easily widened or narrowed, allowing the operator to determine the size of the final particles to be crushed.

At this time, the gap adjustment between the damper plate 510 and the secondary crushing roll 300 is rotated back and forth by turning the bolt head portion formed at the rear end of the fixed bar 540 using a separate tool directly by the operator as described above. It can be adjusted simply by, or by advancing the fixed bar 540 back and forth using a drive means it is possible to easily adjust the distance between the damper plate 510 and the secondary crushing roll (300).

In this way, the final crushed crushed products are seated on the conveyor belt 400 provided directly below the secondary crushing roll 300, and the crushed products are transferred to the subsequent process.

As such, by using the damper 500, the waste is uniformly crushed to a desired size to maximize its recycling efficiency.

As described in detail above, the present invention improves the quality when recycling the finished final shredding uniformly by fuel, etc., and furthermore can freely adjust the particle size of the shredding as necessary to vary the size It is possible to provide a crush of.
