Description

  The present invention relates to a waste material polishing apparatus and a polishing method thereof, and more particularly, to a waste material polishing apparatus and a polishing method thereof for processing a waste material such as a crushing insulator into a recycled material.

  2. Description of the Related Art Conventionally, for example, in power relations, insulators attached to utility poles, steel towers and the like for insulating and supporting electric wires are well known. At present, most of this insulator is disposed of. However, this disposal measure is an important issue that must be considered in order to maintain a rich global environment, such as dealing with the depletion of industrial waste disposal sites and the reuse of valuable resources.

  Therefore, in recent years, from the viewpoint of effective use of resources, industrial waste such as insulators has been reused (see, for example, Patent Document 1). Generally, an insulator has a structure in which a metal body such as a cap is provided on an insulator body made of earthenware or the like. When this insulator is used, it is separated into an insulator body and a metal fitting. The insulator body is reused as a road paving material in a crushed state (hereinafter referred to as a crushed insulator), and the metal fitting is reused as a metal product.

  When the crushing insulator is reused as an aggregate for road pavement, the crushing insulator is crushed into a predetermined size by a crusher. Because the crushed insulator is strong and brittle, the shape when crushed is flat compared to general aggregates other than the crushed insulator, and its peripheral part is sharp enough to be comparable to a blade The shape is extremely dangerous in terms of workability and handling during road paving.

  Further, a waste material chamfering apparatus for chamfering corners of waste material is known (see, for example, Patent Document 2). In such a chamfering apparatus, stirring blades are provided on the inner surface of the peripheral wall of the rotating drum, and a large number of abrasives are put into the rotating drum together with waste materials. The rotating drum is rotated, and the corners of the waste material are polished while stirring the waste material and the abrasive material with the stirring blade.

JP-A-10-137623 JP 2007-276074 A

  Since the chamfering apparatus described in Patent Document 2 uses a large number of metal abrasives, it requires a large number of abrasives and a magnetic sorter that removes the metal abrasives from the scrap after the polishing process is completed. Thus, there is a problem that the apparatus becomes complicated. In addition, since the chamfering apparatus is configured to only stir the waste material and the abrasive with the stirring blade, even if chamfering of the waste material having sufficiently lower hardness than the abrasive is possible, the method of Patent Document 1 The shape of the crushing insulator obtained by the method is irregular and strong, and is not suitable for polishing a sharp tip stably and uniformly.

  An object of the present invention is to efficiently and stably polish a sharp tip of a waste material with a simple apparatus when reusing the waste material such as a crushing insulator for mass production.

Solving means taken by the present invention, the horizontal axis is rotated in the direction by the rotary drive unit, a rotating drum waste material from the hopper provided on one is turned on, it is fixed to the rotating the drum, the rotation scattering and Kakiage Ru掻揚means rotates waste that is put into the rotating drum with the drum, secured to said rotating the drum, the waste material collide waste that has fallen in after being Kakiage by the掻揚means and a polishing accelerator means for, by waste to the scatter collide with waste material accumulating at the bottom of the rotating drum, the leading end of each waste is ground mutual rubbing each other, the other of the rotating drum In the waste material polishing apparatus provided with a discharge port for discharging the processed waste material, a plurality of processing chambers are partitioned by a control plate in the rotating drum from the hopper side to the discharge port side. The process chamber is provided with the scraping means and the polishing accelerating means, and the control plate allows a part of the waste material accumulated in the upstream processing chamber to move to the downstream processing chamber. It has an opening .

In this waste material polishing apparatus, the waste material thrown into the rotating drum is lifted up by a lifting means that rotates together with the rotating drum. Further, due to the rotation of the rotating drum, the waste material naturally falls from the scraping means and collides with the polishing promoting means below. Such polishing promoting means scatters the waste material in an irregular direction (arbitrary direction). The scattered waste material collides with the waste material accumulated in the lower part of the rotating drum. Then, due to the impact at that time, the tips of the respective waste materials are rubbed against each other and polished.
Further, in this waste material polishing apparatus, it is possible to accumulate a predetermined amount of waste material in each processing chamber, and to efficiently and stably process the waste material continuously in each processing chamber.

In the method for polishing waste material according to the present invention, the waste material thrown into the rotating drum rotated by the rotation driving device is lifted up by a lifting means provided in the upstream processing chamber , and the waste material is further lifted up. The waste material that has fallen down is collided with the polishing facilitating means and scattered, and the scattered waste material collides with the waste material that accumulates in the lower part of the rotating drum. polished mutual rubbing each other, through the opening of the control plate moves the portion of the waste material into the processing chamber on the downstream side, in Rukoto to discharge the treated waste from the discharge port.

It is set to an arbitrary height at which a fixed amount of crushed insulator 8 can be accumulated.

  Inside the first chamber 15 and the second chamber 16, scraping means 20 for scrap material and polishing promoting means 25 are provided. Hereinafter, the rake means 20 and the polishing promoting means 25 in the first chamber 15 will be described.

  The scraping means 20 is formed of a long square member provided on the inner surface of the peripheral wall of the rotating drum 10 and along the longitudinal direction. A plurality of rake means 20 are arranged in parallel in the circumferential direction of the rotating drum 10 at a predetermined interval. The lifting means 20 has a function of lifting the crushing insulator 8 in the rotating drum 10 and dropping it naturally when the rotating drum 10 rotates. The protruding height (the length in the center direction of the rotating drum 10) of the lifting means 20 can be arbitrarily set so that a predetermined amount of the crushing insulator 8 can be lifted. Moreover, even if all the heights of the raising means 20 are the same, you may arrange | position different things alternately.

  The polishing promoting means 25 includes first polishing promoting members 26 a and 26 b and a second polishing promoting member 27. The first polishing accelerating members 26a and 26b are formed of a long body such as a plurality of long steel pipes or deformed reinforcing bars (deformed bar steel). That is, the first polishing promoting members 26a and 26b are formed by arranging a pair of long bodies in the diameter direction of the rotating drum 10 so as to intersect in an X shape as shown in FIGS. It is. One first polishing promoting member 26 a has one end (the right side shown in FIG. 6) connected to the upstream side of the rotating drum 10 and the other end connected to the downstream side of the rotating drum 10. The other first polishing promoting member 26 b has one end connected to the downstream side of the rotating drum 10 and the other end connected to the upstream side of the rotating drum 10.

  The first polishing accelerating members 26 a and 26 b are configured to abut (collision) after the crushing insulator 8 lifted by the lifting means 20 falls from the lifting means 20. And the 1st grinding | polishing promotion member 26a, 26b is provided with the function to which the colliding crushing insulator 8 is scattered toward arbitrary directions.

  The second polishing promotion member 27 is provided on both sides of the first polishing promotion members 26a and 26b. The second polishing promoting member 27 is formed of a long body such as a long steel pipe or a deformed reinforcing bar, and both ends thereof are supported by the support member 28. The plurality of second polishing promoting members 27 are supported so as to be parallel to each other with a predetermined distance from the inner surface of the peripheral wall of the rotating drum 10. The second polishing promoting member 27 also has a function of scattering the crushing insulator 8 in an arbitrary direction.

  As shown in FIGS. 1 and 5, the second chamber 16 also includes the scraping means 20 and the polishing promoting means 25 for the waste material. They are respectively provided at positions rotated in the circumferential direction of the 90 ° rotating drum 10 with respect to the rake means 20 and the polishing promoting means 25 in one chamber. In FIG. 6, the lifting means 20 and the polishing promoting means 25 in the second chamber 16 are not shown.

  As shown in FIG. 4, a rectangular maintenance inspection opening 13 is formed in a portion of the rotating drum 10 where the first chamber 15 and the second chamber 16 are provided. The inspection opening 13 can be freely opened and closed by an inspection lid 14. A second polishing promoting member 27 is provided along the opening edge of the inspection opening 13. In addition, the rotation drum 10 reduces the strength with respect to the torsional direction and the like by forming the inspection opening 13. However, since the support member 28 is provided in the vicinity of the four corners of the inspection opening 13 and supports the second polishing promoting member 27, the second polishing promoting member 27 has a function of a reinforcing material. The inspection opening 13 is not necessarily provided.

  In addition, a discharge port 10 a through which the processed crushing insulator 8 is discharged is formed at the other end of the rotating drum 10.

  The rotation driving device 5 includes four rollers 30a, 30b, 30c, and 30d that are provided on the support base 2 and rotatably support the rotating drum 10, a motor 31 that rotates the roller 30a, and a roller 30a. And a connecting shaft 32 for interlockingly connecting the roller 30b. The motor 31 is controlled by a control panel (not shown) so that the rotating drum 10 can be rotated at a predetermined rotational speed.

  The waste material polishing apparatus 1 of the present embodiment has the above-described configuration. Next, a case where the crushing insulator 8 is polished using the apparatus 1 will be described.

  First, the insulator is crushed into a predetermined size in advance using a known crusher, and the crushed insulator 8 and the metal fitting are separated. In addition, the crushing insulator 8 is so sharp that its peripheral part is comparable to a blade (see FIG. 8A).

  The crushing insulator 8 is appropriately transported by a belt conveyor (not shown) and put into the hopper 7. The crushing insulator 8 put into the hopper 7 is put into the first chamber 15 from one end of the rotating drum 10 that rotates at a predetermined speed.

  The crushing insulator 8 put into the first chamber 15 is accumulated in the first chamber 15 by contacting the first control plate 11 and being prevented from moving to the second chamber 16 on the downstream side. The crushing insulator 8 in the first chamber 15 is lifted up by a lifting means 20 that rotates together with the rotating drum 10.

  Further, by the rotation of the rotating drum 10, the crushing insulator 8 raked up to a predetermined height naturally falls from the rake means 20 and collides with the lower polishing accelerating means 25.

  That is, since the surfaces of the first polishing promoting members 26a and 26b are uneven or slippery and are inclined, the crushing insulator 8 that collides with an arbitrary portion of the polishing promoting members 26a and 26b is irregular. Then, it collides with the crushing insulator 8 that accumulates in the lower part of the rotating drum 10. Then, due to the impact at that time, the tips of the crushing insulators 8 are rubbed against each other and polished.

  Similarly, the crushing insulator 8 dropped from the lifting means 20 having a predetermined height also collides with the second polishing promoting member 27. The second polishing promoting member 27 is different in structure from the first polishing promoting members 26a and 26b, and is provided at a position away from the first polishing promoting members 26a and 26b. The crushing insulator 8 that did not collide with 26a, 26b also collides.

  The crushing insulator 8 scatters in an irregular direction and collides with the crushing insulator 8 accumulated in the rotating drum 10. Then, due to the impact at that time, the tips of the crushing insulators 8 are rubbed against each other and polished.

  The crushing insulator 8 that collides with one of the first polishing promoting members 26a and 26b and the second polishing promoting member 27 may also collide with the other.

  Thus, by the rotation of the rotating drum 10, the lifting action of the crushing insulator 8 by the lifting means 20 and the scattering collision action of the crushing insulator 8 by the polishing promoting means 25 are repeated (see FIG. 7A).

  When the crushing insulators 8 are sequentially introduced from the hopper 7, the amount of the crushing insulators 8 in the first chamber 15 increases, so that the accumulated crushing insulator 8 upper part slides and the first through the opening 11a of the control plate 11. It moves to the second chamber 16 (see FIG. 7B). Also in the second chamber 16, the tip of the crushing insulator 8 is further polished and rounded by repeating the lifting action of the crushing insulator 8 and the scattering collision action of the falling crushing insulator 8 in the same manner as described above. Take good.

  Further, when the crushing insulator 8 is inserted, the amount of the crushing insulator 8 in the first chamber 15 and the second chamber 16 increases, so that the upper part of the second chamber 16 slides while colliding with each other. It moves from the opening 12a of the plate 12 to the third chamber 17 (see FIG. 7C).

  In the third chamber 17, only the lifting means 20 is provided, and the polishing promoting means 25 is not provided. Therefore, the crushing insulator 8 moves downstream while being lifted, and is provided at the other end of the rotating drum 10. The discharged outlet 10a is discharged. The discharged crushing insulator 8 is supplied to a sieving device 35 disposed at the lower part of the other end of the rotating drum 10. The sieve device 35 is classified into three types of recycled materials. Thus, the classified crushing insulator 8 can be effectively used as an aggregate (see FIG. 8B).

  As described above, since the waste material polishing apparatus 1 according to the present embodiment does not use a large number of metal abrasives unlike the prior art, a large number of abrasives and metal abrasives are removed from the waste material after the polishing process is completed. A magnetic sorter is not required, and the apparatus can be simplified. Moreover, it is possible to stably and evenly polish the sharp tip portion having an irregular shape and a strong shape such as the crushing insulator 8.

  The present invention is not limited to the embodiment described above. For example, the waste material polishing apparatus 1 shown in FIG. 9 includes a long body such as a steel pipe or a deformed reinforcing bar in which the first polishing promoting members 26a and 26b are curved in an S shape. The first polishing promoting members 26a and 26b can be curvedly formed in any shape other than the S-shape.

  The first polishing promoting members 26 a and 26 b are also provided in the third chamber 17. Note that the same members as those in the waste material polishing apparatus 1 shown in FIG.

  Further, the polishing promoting means 25 can be provided only in the first chamber 15. Further, the rotating drum 10 can be supported at a predetermined angle so as to gradually decrease from the upstream side on the hopper 7 side toward the downstream side on the discharge side. Thus, by tilting the rotating drum 10, the timing at which the crushing insulator 8 in each chamber of the first chamber 15, the second chamber 16, and the third chamber 17 moves to the next processing chamber can be adjusted. . Note that the fact that the support base 2 is rotatable about the horizontal axis means that the state in which the rotating drum 10 is arranged horizontally includes, of course, a slight tilt.

  As shown in FIGS. 10 and 11, the present invention can employ a batch-type waste material polishing apparatus 1. In this waste material polishing apparatus 1, the rotary drum 10 has a hexagonal cross-sectional shape. Further, in the rotating drum 10, scraping means 20 for waste material and first polishing promoting members 26 a and 26 b as polishing promoting means 25 are provided. In the waste material polishing apparatus 1 of this embodiment, the crushing insulator 8 is input from an input port 19 formed in the rotating drum 10. The inlet 19 can be opened and closed by a closing lid 18.

  Then, when the rotating drum 10 is rotated by the motor 31, the tip of the crushing insulator 8 is polished by the lifting action by the lifting means 20 and the scattering collision action by the polishing promoting means 25 as in the above embodiment. It becomes round and the polishing condition is good. After completion of the polishing process, the crushing insulator 8 in the rotating drum 10 is taken out from the inlet 19.

  The crushing insulator 8 that has been polished as described above and whose surface is rounded can be reused as a paving stone for garden stones, artificial rivers, and the like in addition to construction.

  The waste material is not limited to the insulator, and may be ceramic tableware, glass, roof tiles, or the like.
