Description

  The present invention relates to an apparatus for producing a granular tile material for producing a granular tile material obtained by crushing tiles.

In recent years, the promotion of the reuse of industrial waste has been widely recommended due to the increasing social momentum regarding environmental problems.
Now, tiles that are widely used as roofing materials are generally obtained by firing clay, so even if the waste materials (waste tiles) are disposed of in the natural environment, problems such as environmental pollution will occur. Although it is not caused, a method for reusing waste tiles is being sought because of the shortage of disposal sites due to the recent increase in the amount of industrial waste and the social resistance to disposal.
In addition to reducing waste, the tiles are porous and have adequate water retention and water permeability, so if they are crushed into particles of an appropriate particle size, mortar and roof Nanban plaster It has been known that it can be suitably reused as a raw material (aggregate), laid sand, un-to-car, and the like.
Therefore, the applicant of the present application has previously proposed a roll shaft type crusher capable of suitably crushing roof tiles into granular shapes suitable for reuse in Patent Documents 1 and 2.

By the way, since the roof tile is a kind of a ceramic baked clay, when it is crushed by a conventional crusher such as the roll shaft crusher, a sharp corner is formed on the chipped surface. In this case, when the crushed tile material is used as garden sand, for example, when a person falls over it, the corner of the tile surface may pierce the skin and cause injury There is.
As described above, the conventional manufacturing method of the granular tile material and the conventional manufacturing apparatus such as the crusher have a problem that a safety problem arises because the surface of the manufactured granular tile material has a sharp corner.

  Moreover, when glaze is hung on the surface of a tile, this glaze will remain in the crushed granular tile material. If glaze remains on the surface of the granular roof tiles, the water permeability and water retention of the roof tile may be hindered, and the lead of harmful substances that may be contained in the glaze may melt and cause environmental pollution. There is a problem that there is.

  The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to improve safety and appearance from the tiles such as waste tiles, because there are no sharp corners on the surface, and the glaze has been removed from the surface. An object of the present invention is to provide an apparatus for producing a granular tile material capable of producing a granular tile material.

In order to solve the above-mentioned problems, a granular tile material manufacturing apparatus according to the present invention has the following configuration.
That is, a crushing portion that crushes the tiles that have been thrown into particles, and a screw conveyor in which a screw having a rotating shaft and a spiral blade formed on the outer periphery of the rotating shaft is provided in a trough so as to be rotationally driven. A surface of the granular roof tile by conveying the granular roof tile crushed by the crushing section obliquely upward with the screw conveyor, the stirring member provided to connect the spiral blades to the screw It is possible to form a granular tile material having a rounded surface.
According to this, the granular roof tiles crushed in the crushing part are rubbed with the inner circumferential surface of the trough, the surface of the spiral wing, and the granular roof tiles, and the surfaces are polished, and the corner tiles of the surface are removed. It becomes. In particular, since the granular roof tile is stirred by the stirring member so as to be scraped up along the inner peripheral surface of the trough, the surface of the granular roof tile is effectively polished.

Furthermore, the surface shape of the stirring member on the front side in the rotation direction of the screw is formed in a concave shape.
According to this, since the granular roof tiles are housed in the concave portions and a large amount is scraped up, they are stirred more efficiently.

Further, a clearance is formed between the stirring member and the rotating shaft.
According to this, a granular roof tile passes between between a stirring member and a rotating shaft, and is conveyed upwards with a screw conveyor (spiral feather).

In addition, the trough is characterized in that an axis is inclined so that an end portion in front of the screw conveyor in the conveying direction is positioned upward.
According to this, since the granular roof tiles stay behind in the transport direction in the trough due to gravity, the granular roof tiles rub against each other well and polishing can be performed effectively.

In addition, a discharge port for discharging the granular roof tiles to the outside of the trough is formed at an end portion of the trough in front of the conveying direction of the screw conveyor.
According to this, the granular roof tile (namely, the completed granular roof tile material) conveyed to the edge part ahead of the conveyance direction of a screw conveyor can be discharged | emitted out of a trough from a discharge port.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the best mode for producing a granular tile material according to the present invention will be described.
FIG. 1 is an explanatory diagram showing a configuration of a granular tile material manufacturing apparatus A according to the present embodiment.
The granular tile material manufacturing apparatus A includes a roll shaft type crushing device B as a crushing unit for crushing the tiles into particles, and a screw conveyor C into which the tiles crushed by the roll shaft type crushing device B are placed.

(Roll shaft type crusher B)
An explanatory view of the roll shaft crusher B is shown in FIG. 2A is a plan view of the roll shaft crusher B, FIG. 2B is a front view, and FIG. 2C is a right side view.
As shown in FIG. 2, the roll shaft type crusher B rotates the box-shaped main body 2, two (plural) roll shafts 4, 5 provided in the main body 2, and the roll shafts 4, 5. And a motor 6 as a roll shaft driving device.

The main body 2 has a hopper 2a that opens upward as a primary inlet into which tiles to be crushed are introduced, and a lower end that opens as a primary outlet 2b.
The two roll shafts 4 and 5 are rotatably supported by the main body 2 in a horizontal manner, their axis lines are arranged substantially parallel to each other, and are driven to rotate in conjunction with each other via gears 4b and 5b. It is provided and crushes with a roof tile between the opposing surfaces.
The motor 6 has a drive shaft 6a provided with a chain wheel 6b, and an endless chain 8 wound around the chain wheel 4c provided at the end of the roll shaft 4 and the chain wheel 6b (see FIG. 2C). ) To rotate the roll shafts 4 and 5.

As shown in FIG. 2A, each of the roll shafts 4 and 5 is constituted by a plurality of disk-like members 10, 10,.
The shape of the disk-shaped member 10 is shown in FIG. FIG. 3A is a side view of the disk-shaped member 10 viewed from the axial direction of the roll shaft 4, and FIG. 3B is a direction orthogonal to the axial direction of the roll shaft 4. It is the front view seen from. As shown in FIGS. 3A and 3B, the disc-like member 10 is formed in a sprocket shape. That is, the protruding teeth 10a, 10a,... Having a sharp side section are formed in a gear shape provided on the outer peripheral portion at a constant period.
The roll shafts 4 and 5 are configured such that adjacent disc-like members 10A and 10B are arranged so that the tips of the respective projecting teeth 10Aa and 10Ba of the sprocket are alternately positioned (see FIG. 4).
In addition, the shape of each disk-shaped member 10 can be set arbitrarily, and the roll shafts 4 and 5 can also be configured by combining disk-shaped members 10, 10.

  In the roll shafts 4 and 5, rotary shaft portions 4 d and 5 d that are rotationally driven by the motor 6 via the endless chain 8, the chain wheel 4 c, and the gears 4 b and 5 b are formed at the center of each disk-like member 10. It is configured to be inserted through the through hole 10b (see FIG. 3). The rotation shaft portions 4d and 5d are formed with protrusions 4da and 5da on the outer peripheral surface thereof in parallel with the axis thereof, and the inner periphery of one through hole 10b is engaged with the protrusions 4da and 5da. An engaging portion 10c is formed.

Further, the protrusions 4da and 5da are provided so that there is some play 12 in the rotation direction (that is, the circumferential direction) of the roll shafts 4 and 5 with respect to the engaging portion 10c.
The amount of the play 12 may be provided so as to be different for each disk-like member 10. This can be realized, for example, by making the circumferential lengths of the engaging portions 10c of the respective disk-like members 10 different.
An elastic member or the like may be provided in the play 12 so that a predetermined operating resistance is generated when the disc-like member 10 plays with respect to the rotating shaft portions 4d and 5d.

In this way, each of the disk-shaped members 10, 10... Is configured by forming the roll shafts 4, 5 by inserting the rotating shaft portion through the through-hole 10 b and overlapping in the axial direction. It is possible to easily exchange or recombine the members 10, 10,.
As a result, by combining disc-shaped members having different shapes and exchanging or recombining them, the roll shaft can be easily and inexpensively cut without cutting the roll shaft surface or replacing the entire roll shaft. The surface shape can be changed.
For example, when the roll shafts 4 and 5 are configured by only the sprocket-like disk-like members 10, 10,. The roll shafts 4 and 5 are formed by alternately superimposing the disk-shaped members 10 and the peripheral surface having a flat outer peripheral portion, i.e., the perfect disk-shaped disk-shaped members 10. It is possible to take measures such as reducing the density of the protruding teeth 10a on the outer peripheral portion to suppress the excessive engagement of the protruding teeth 10a.

  Further, since the disk-shaped member 10 is mounted with a predetermined play in the rotation direction of the roll shafts 4 and 5, when an excessive force is applied to the roll shafts 4 and 5, the force is Since the disk-shaped member 10 of the hooked part escapes in the rotation direction of the roll shafts 4 and 5, the roof shaft is not locked due to clogging. In addition, the escape portion is limited to a part of the roll shafts 4 and 5, and the tile is normally crushed in the other most part, so that the tile is not discharged without being crushed.

(Screw conveyor C)
Next, the configuration of the screw conveyor C will be described.
As shown in FIG. 1, the screw conveyor C is supported by the legs 26 and 26 so that one end is below the primary discharge port 2b of the roll shaft crusher B and the other end is obliquely upward, and is about 30 °. A cylindrical trough 20 disposed in an inclined manner, a screw 22 having a rotating shaft 22b provided in the trough 20, and a spiral blade 22a formed on the outer periphery of the rotating shaft 22b, and the screw 22 are driven to rotate. And a motor 24 as a screw driving device (in FIG. 1, the screw 22 is shown through the trough 20).
The shape of the trough 20 is not necessarily limited to a cylindrical shape, and may be formed in, for example, a U-shaped groove shape.

The trough 20 has an opening formed on the upper surface on the one end side, and a hopper 20a is attached to the opening. The hopper 20a functions as a secondary input port through which the crushed granular roof tile discharged from the primary discharge port 2b of the roll shaft crusher B is input into the screw conveyor C.
On the lower surface of the other end of the trough 20, an opening is formed as a secondary discharge port 20b. In addition, this secondary discharge port does not necessarily need to be formed in the lower surface of the trough 20, For example, the said other end of the cylindrical trough 20 is provided in an opening end, and the said opening end is good also as a secondary discharge port.

FIG. 5 is an enlarged view of the screw conveyor C. FIG.
On the screw 22 of the screw conveyor C, a plurality of stirring members 23 provided so as to connect the spiral feathers 22a are attached by welding or screwing, for example. The connection between the spiral wings 22a means, in other words, the connection between almost one pitch of the spiral wings 22a. In other words, it can be said that the gap in the axial direction of the spiral wing 22a that makes a round around the spiral rotation shaft 22b is connected. However, the stirring member 23 is not limited to a configuration in which one pitch (one round) of the spiral is strictly connected. For example, the stirring member 23 extends in a direction slightly inclined with respect to the axis of the spiral and extends between the spiral blades 22a. What provided so that it may connect is also contained in this invention.

FIG. 6 is an explanatory view of the screw 22 as seen from the axial direction of the rotary shaft 22b.
The stirring member 23 is attached near the outer peripheral edge of the spiral wing 22a. As shown in FIG. 6, in particular, the edge 23b on the outer peripheral side of the spiral of the stirring member 23 may be disposed on the outer peripheral edge of the spiral.
Moreover, the surface shape of the stirring member 23 on the front side 23a in the rotation direction a of the screw 22 is formed in a concave shape.
A clearance 25 is formed between the stirring member 23 and the rotating shaft 22b.

  Next, the manufacturing method of the granular tile material using the granular tile material manufacturing apparatus A according to the present embodiment will be described.

(Crushing process)
First, an operator throws tiles such as waste tiles into the hopper 2a of the roll shaft crusher B (see FIG. 1). The roof tiles enter between the rotationally driven roll shafts 4 and 5 and are crushed therebetween. In addition, the space | interval between the roll shafts 4 and 5 and the magnitude | size and shape of the protrusion tooth | gear 10a are set so that the particle size of the granular roof tile formed by crushing may be 40 mm or less, more preferably 20 mm or less.

  The granular roof tiles crushed by the roll shaft type crusher B are discharged from the primary discharge port 2b and dropped, introduced into the screw conveyor C from the hopper 20a of the screw conveyor C, and conveyed obliquely upward by the screw conveyor C. The

(Polishing process)
The granular roof tiles that have entered the screw conveyor C are collided and rubbed with the inner peripheral surface of the trough 20, the surface of the spiral blade 22a, and particles of various particle sizes, and the surface is polished. .

  The trough 20 is disposed such that its axis is inclined such that the front end of the screw conveyor C in the conveying direction is positioned upward. Therefore, since the granular roof tiles in the trough 20 stay behind in the transport direction in the trough 20 due to gravity, the granular roof tiles rub against each other well and polishing can be effectively performed.

The granular roof tiles in the trough 20 are scraped up along the inner peripheral surface of the trough 20 by the stirring member 23 provided to connect the spiral blades 22a. As a result, the granular roof tiles abut against the inner peripheral surface of the trough 20 over a longer distance and are rubbed, and further, the particles are rubbed against each other so that the polishing proceeds more effectively.
Furthermore, since the surface shape of the front side 23a of the stirring member 23 in the rotational direction a of the screw 22 is formed in a concave shape, the granular roof tiles in the trough 20 are housed in the concave portion and a large amount is scraped up. , More efficiently stirred and polished.

  Further, since the clearance 25 is formed between the stirring member 23 and the rotating shaft 22b, the granular roof tile passes between the stirring member 23 and the rotating shaft 22b, and the screw conveyor C (spiral blade 22a). ).

  When the granular roof tile in the trough 20 is conveyed to the other end of the trough 20, it is discharged out of the trough 20 from the secondary discharge port 20b, and becomes a granular roof tile with a rounded surface.

Next, another configuration example of the screw conveyor C will be described. Another configuration example is shown in an explanatory diagram of FIG.
In the screw conveyor C shown in FIG. 7, the trough 20 has a portion 20 c where a hole is not formed extending from one end where the hopper 20 a is provided, and a forward direction of the screw conveyor C from the portion 20 c. (I.e., from the middle of the conveying path of the screw conveyor C), a portion 20d where a plurality of first sieve holes are formed over a predetermined length, and further forward in the conveying direction from the portion 20d to a predetermined length. And a portion 20e where a plurality of second sieve holes are formed.
Although not particularly limited, the inventor of the present application has a length of the portion 20c where the hole is not formed is about 1500 mm, a length of the portion 20d where the first sieve hole is formed is about 1470 mm, and the second The length of the portion 20e where the sieve hole is formed is set to 1343 mm, and it has succeeded in obtaining a suitable granular tile material.

The first sieve hole 20f and the second sieve hole 20g are a plurality of circular openings as shown in FIGS. 8A and 8B, respectively.
The diameter of the first sieve hole 20f is preferably about 4 mm to 8 mm, and the distance between the centers is preferably about 8 mm to 12 mm. More preferably, as shown in FIG. 8A, the diameter is 6 mm and the center interval is 10 mm.
The diameter of the second sieve hole 20g is preferably about 12 mm to 18 mm, and the distance between the centers is preferably about 16 mm to 24 mm. More preferably, as shown in FIG. 8B, the diameter is 15 mm and the center interval is 20 mm.
The first sieve holes 20f and the second sieve holes 20g are not limited to being formed with the same diameter and the same interval, and may be formed by combining a plurality of types of diameters and / or intervals.

  The configuration of the screw and stirring member of the screw conveyor C in FIG. 7 is the same as the configuration of the screw 22 and stirring member 23 shown in FIGS.

  Further, as shown in FIG. 7, on the outer surface of the trough 20, the granular tile materials discharged from the first sieve hole 20 f and the second sieve hole 20 g are separated into collection boxes 40 and 42 for collection.樋 -shaped (groove-shaped) guide portions 28 and 30 are provided. A collection box 44 for collecting the granular roof tiles discharged from the opening 20b is disposed below the opening 20b.

A polishing process using the screw conveyor C shown in FIG. 7 will be described.
The granular roof tiles that have entered the screw conveyor C in FIG. 7 collide with each other between the inner peripheral surface of the trough 20 and the surface of the screw 22 and particles of various particle diameters at a portion 20c where no hole is formed. The surface is polished by rubbing or rubbing.
Subsequently, the granular tile is conveyed to a portion 20d where the first sieve hole 20f having a diameter of 6 mm is formed, and the granular tile having a diameter smaller than the diameter of the first sieve hole 20f is passed through the first sieve hole 20f to the trough 20. It is discharged outside, guided to the guide portion 28 and collected in the collection box 40. On the other hand, the granular roof tile having a larger diameter is further polished in the trough 20.
Further, the granular roof tile is conveyed to a portion 20e where the second sieve hole 20g having a diameter of 15 mm is formed, and the granular roof tile having a diameter smaller than the diameter of the second sieve hole 20g is removed from the trough 20 through the second sieve hole 20g. And is guided to the guide unit 30 and collected in the collection box 42.
The granular roof tile having a larger diameter is conveyed to the other end of the trough 20, discharged from the opening 20 b to the outside of the trough 20, dropped into the collection box 44, and collected.

By adopting the configuration of the screw conveyor C shown in FIG. 7, in addition to the above effect obtained by the screw conveyor C shown in FIG. 5, the granular tile material can be sorted according to the particle size. The larger the diameter of the tiled tile material, the higher the danger due to the sharp point of the surface and the conspicuous appearance, which will be discharged later from the trough 20, so that more polishing can be performed.
Further, the granular roof tiles collide with the edges of the first sieve hole 20f and the second sieve hole 20g of the trough 20, so that the granular roof is used in comparison with the case where a trough without a hole is used (FIG. 5). A strong load is applied to the roof tile, and polishing is efficiently performed.

According to the granular tile material manufacturing apparatus A according to the present embodiment, a sharp portion (corner) of the surface is removed from a tile such as a waste tile, and it is suitable for various applications that are excellent in safety and appearance.
