Description

  The present invention relates to an apparatus for crushing, crushing, peeling, and screening.

  In recent years, the need to recycle waste materials has been increasing, but in most cases, various materials are accumulated in a mixed state in the waste materials, so various attempts have been made to develop means for separating and collecting recycled materials from waste materials. It has been. For example, in order to reuse the soil wall of a demolished house, it is necessary to separate the soil block from firewood, bamboo, and other pieces of wood mixed during dismantling. Further, in order to reuse the waste gypsum board, it is necessary to separate the core gypsum from the surface paper.

  The invention described in Patent Document 1 has an object of recovering recycled raw material components from waste at a high recovery rate and in a size suitable for recycling. In Patent Document 1, a cylindrical main body case 301 arranged horizontally, an input port 302 for introducing waste from the upper part of one end of the main body case 301, a drive shaft 303, and a drive shaft 303 A rotating disc 304 that is fixed, a chain blade 305 that has a jump rope shape by fixing both ends at a distance from the outer periphery of the rotating disc 304, and an outer periphery that is fixed to the inner peripheral surface of the main body case 301 A fixed blade 306 and a discharge port 307 provided on the lower side of the main body case 301 at the end opposite to the input port 302 are provided. A number of rotating disks 304 are fixed to the drive shaft 303 at a predetermined pitch. In the adjacent rotating disks 304, the attachment position of the chain blade 305 is shifted by 90 degrees, and the outer peripheral fixed blade 306 is close to the insertion port 302. Is intended a low height, as the closer to the discharge port 307, which it describes the invention of fine crushing device according to claim configured as gradually height increases.

Japanese Patent No. 3556627

  However, in the invention of Patent Document 1, the chain blade 305 fixed at both ends has a rotation range such as a rope-like mountain of jumping rope in the axial direction of the rotation axis. Since a valley-shaped dead space is generated between the blades 305, an object that is not crushed accumulates and becomes a problem. Further, the crushing efficiency is also lowered by the fact that the outer peripheral fixed blade 306 located here prevents the crushing material from being discharged and fed.

  Then, this invention makes it a subject to provide the crusher which avoided the above dead spaces and improved crushing efficiency.

  In view of the above-described problems, the present invention provides a shaft that is rotatably supported and a linear member having flexibility that are spirally connected to the outer peripheral surface of the shaft along the axial direction of the shaft. It is a crusher characterized by being installed. Specifically, a shaft that is rotatably supported, and a flexible linear body that is provided with both ends spaced apart at a predetermined interval in the axial direction of the shaft and spaced at a predetermined angle in the circumferential direction. The crusher is characterized in that it is helically formed along the shaft by providing a plurality of the filaments with a predetermined interval in the axial direction and with a predetermined angle in the circumferential direction. . Here, the continuous arrangement of the striates includes ones in which both ends of the striates are connected, ones arranged in the vicinity, and ones separated from each other. It is preferable that both ends of the linear body are fixed to the shaft.

  The crushing here includes rough crushing and crushing of materials. Moreover, the crusher by this invention can make use of all the results which arise by the collision with the rotating linear body besides crushing. For example, it is possible to crush only a part of a crushing object in which a plurality of materials are mixed, peel off a clogging object to which a different substance is attached, or screen them.

  The striated body includes all striated bodies having flexibility. A chain having flexibility in three dimensions is suitable as the linear body. The chain refers to a chain of rigid elements having an annular wire. The linear body is not limited to this, and may be applied to a rope or the like in which a string-like object is further combined depending on its flexibility / flexibility and the object to be crushed.

  The striated body includes a plurality of striated wires by substantially tangling a single striated body to the shaft and fixing a plurality of intermediate portions at a predetermined interval and a predetermined angle as described above. It can be similar to providing a body.

  In the individual attachment of the linear body, the axial interval and the circumferential attachment rotation angle can be arbitrarily selected.

  Further, the present invention provides a plurality of rotating disks whose rotating shafts coincide with the shaft at a predetermined interval perpendicular to the shaft, and one end and the other end of the linear member are placed between the separate rotating disks. It is a crusher characterized by being handed over.

  In the present invention, there is provided a spiral disk that is provided in a spiral shape integrally with the shaft by standing in the radial direction from the shaft and continuously transitioning in the axial direction, and the filament is interposed through the spiral disk. It is good also as fixing a body.

  In addition, the present invention includes a crusher having a charging port and a discharging port, and having a casing that rotatably supports the shaft inside, and a drive unit that provides rotational force to the shaft. It is.

  Moreover, this invention is a crusher characterized by providing a sieve body inside the said housing and the outer side of the rotation radius of the said linear body, and providing a sieving discharge port in the said housing.

  In the present invention, the shaft can be provided horizontally or vertically.

  In the present invention, a heavy object such as an iron ball is provided on the striated body to improve the pulverizing force, or an iron lump having a chamfered corner is provided as a cutting blade to give a cutting force of the material. You can also. Moreover, cutting force can also be provided to the said linear body itself using the raw material which has a corner | angular part.

  In the crusher of the present invention, the use of a flexible linear body as a crushing rotary blade causes material selectivity due to bending of the linear body. For example, the earth wall can be crushed while avoiding crushing of scum and the like in the earth wall, the mixed material can be selected and crushed, and the material can be separated and collected. Since such material selectivity can be adjusted by the weight of the striate body, the bending length, the rotational speed, etc., it can be adapted to various materials. If a chain is provided as a linear body, the above-described material selectivity is suitably generated, and attachment and replacement are facilitated.

  In the crusher of the present invention, the linear body is formed in a spiral shape along the rotation axis, avoiding the valley-shaped dead space generated between the rotating chain blades as described above, and reliably Objects can be crushed. Furthermore, when the filament is rotated in a spiral shape, the object is continuously hit not only outside the rotation radius but also in the direction of the rotation axis, thereby moving the object in the direction of the rotation axis. A material feed force is generated. Therefore, since the object automatically moves toward the downstream in the direction of the rotation axis and is discharged, for example, even when the object is horizontally placed and the rotation axis is horizontal, the object continues to rotate at the same place. There is nothing, and the crushing efficiency can be improved.

  Furthermore, in the crusher of this invention, the attachment space | interval in the axial direction of a filament and the attachment rotation angle of the circumferential direction can be selected arbitrarily, and crushing force and material feeding speed can be adjusted according to material. In addition, by providing an iron ball or rectangular iron ingot, etc., the crushing force can be improved or the cutting force of the material can be given, or the shaft and the striated body can be manufactured or replaced via a rotating disk or spiral disk The scope of application and the range of application are wide-ranging, such as making maintenance easy. In addition, since the crusher of the present invention has a simple structure, it can be manufactured at low cost, is less damaged, and is easy to maintain, so the cost for implementation is low.

  A crusher 1 that is a preferred embodiment 1 of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the crusher 1 includes a shaft 2 that is rotatably supported, a rotating disk 3 that has a rotating shaft that coincides with the shaft 2 and that is orthogonal to the shaft 2, and is provided at predetermined intervals. A chain 4 as a linear body provided on the rotating disk 3 at a predetermined interval in the axial direction and at a predetermined angle in the circumferential direction, the chain 4 having a predetermined interval in the axial direction and By being provided with a plurality of angles with a predetermined angle in the direction, a spiral shape is formed along the shaft 2. Hereinafter, each part will be described.

  As shown in FIGS. 1 and 2, the shaft 2 is a rotating shaft to which a rotating disk 3 having the same rotating shaft is fixed. Although FIG. 1 is a conceptual diagram, details are omitted, but a bearing portion (not shown) for pivotally supporting at both ends and a driving machine (not shown) for applying a driving force to one end. It has a shape to provide. The bearing portion may be provided only at one end to be a single bearing.

  The rotating disk 3 is fixed to the shaft 2 in order to provide the chain 4 as shown in FIGS. Twelve rotating disks 3 are provided on the shaft 2 with a predetermined interval, and each rotating disk 3 is a rotating disk 31, 32, 33,..., 312 as shown in FIG.

  As shown in FIGS. 1 and 3, both ends of the chain 4 are fixed to separate rotating disks 3, and both ends are fixed with a mounting rotation angle that is separated by a predetermined angle in the circumferential direction of the rotating disk 3. One chain 4 provided between two rotating disks 3 is fixed with a certain amount of deflection. Two chains 4 are selected every other, and two chains 4 are provided between a pair of rotating disks 3, and each chain 4 is connected to a chain 41a, 41b, 42a, 42b, 43a as shown in FIGS. , 43b,..., 410a, 410b.

  As described above, the chains 4 are provided in the axial direction of the shaft 2 at intervals twice as large as the intervals between the rotating disks 3. The chain 4 is attached at a predetermined rotation angle, which will be described with reference to FIG. In each rotating disk 3, the points A to H obtained by dividing the periphery into eight equal portions of 45 degrees are set, and the numbers 1 to 12 at the end of the rotating disk are added thereto to call each vertex. Two chains 41 a and 41 b are provided from the rotating disk 31 toward the rotating disk 33. The chain 41a is fixed between the point 1A of the rotating disk 31 and the point 3D of the rotating disk 33, and the chain 41b is fixed between the point 1E of the rotating disk 31 and the point 3H of the rotating disk 33. In other words, the right end of one chain 4 whose left end is fixed to a certain rotating disk 3 is fixed at a position advanced three points clockwise around the two right adjacent rotating disks 3. Further, the base points of the two chains 4 in the same rotating disk 3 are provided at the farthest points opposite to each other by 180 degrees.

  The two chains 42a and 42b provided between the rotating disc 32 and the rotating disc 34 adjacent to the right of the two chains 41a and 41b have a left end base point of point 2B and a point 2F, and one point clockwise. It is provided from the apex rotated by 45 degrees, that is, by 45 degrees. The attachment rotation angle from the left end to the right end is three points clockwise, that is, 135 degrees, like the chains 41a and 41b. Hereinafter, the chains 43a and 43b to the chains 410a and 410b are similarly provided. By providing the chains 41a, 41b, 42a, 42b, 43a, 43b,..., 410a, 410b as described above, the chain 4 rotates as a whole around the shaft 2 in a spiral shape. In the rotary disks 31, 32, 311 and 312 at both ends of the shaft 2, only two base ends or terminal ends of the chain 4 are provided, but between the rotary disk 31 and the rotary disk 32, Another chain 4 may be provided between the rotating disk 311 and the rotating disk 312.

  As described above, each chain 4 has a mounting interval twice as large as the interval of the rotating disks 3, the mounting rotation angle is 135 degrees clockwise, and the rotation angle between the end and the base end of the adjacent chain 4 is 45 degrees clockwise. However, the present invention is not limited to this, and can be provided with any interval, angle, and number. For example, one chain 4 may be provided across two rotating disks 3, the mounting rotation angle may be 120 degrees, or three chains 4 may be provided based on one rotating disk 3. This is because the chains 4 rotate spirally and do not interfere with each other. In addition, it is preferable to provide the base point of the other chain 4 between the both ends of one chain 4 in the axial direction of the shaft 2. This is because the dead space during rotation can be reduced or eliminated.

  The chain 4 is a link chain in which a substantially oval annular body having an outer length of 55 mm × 39 mm is formed from a stainless steel shaft having a diameter of 11 mm to form a frame, and a plurality of frames are formed in a chain by connecting portions. The above numerical values are an example of implementation. For example, when aiming at crushing of earth walls, a short link chain having a nominal diameter of about 8 to 13 mm is preferable. Further, depending on other crushing purposes, a thinner chain or a thick chain can be used. The link chain is preferably a short link chain with a short chain ring on the top, but a long chain ring can also be used.

  Further, as the chain 4, a Mantel chain, a Victor chain, a twist link chain, a ball chain or the like often used for decoration can be applied in the present invention. Depending on the shape of the chain, the main effects such as crushing, crushing, peeling and cutting can be changed.

  Chain 4 can be freely three-dimensionally between frames rather than a chain that is bent only in a certain direction between frames, such as a transmission roller chain used in combination with a sprocket, or a steel wire with limited flexibility. A material that can be bent is preferable, but is not limited thereto. For example, even if it cannot be said that it has free flexibility, it is possible to use a wire, a rough rope, or the like made of a material having a considerable degree of flexibility as a whole by having flexibility.

  As one application example of the crusher 1, a heavy object such as an iron ball can be provided on the chain 4 to improve the crushing force. Further, a cutting blade can be provided on the chain 4 to cut the object. The cutting blade does not necessarily have a general thin blade shape. For example, an iron block having a corner portion without chamfering is preferable.

  Instead of the rotating disk 3, the chain 4 is fixed via a spiral disk provided in a spiral shape integral with the shaft 2 by standing in the radial direction from the shaft 2 and continuously changing in the axial direction. Also good. More specifically, an auger screw can be used as it is instead of the shaft 2 and the rotating disk 3. Alternatively, an attachment plate standing only at the attachment position of the chain 4 may be fixed to the shaft 2.

  Operation | movement of the crusher 1 by Example 1 is demonstrated. The crusher 1 is rotatably fixed in a container in which an object to be crushed is accommodated, and is used with a rotational force applied by a driving machine (not shown). Alternatively, the object is put into the rotating crusher 1 as needed. The crusher 1 can be used regardless of whether the rotation axis is vertical or horizontal. While the shaft 2 rotates, the chain 4 rotates while generating tension by centrifugal force. However, it is not always necessary to rotate while maintaining the maximum rotation radius, and the chain 4 rotates while being bent by its own weight or by contact with an object. can do. Therefore, the shaft 2 can be operated at a low speed. If the rotational speed of the shaft 2 is increased so that the chain 4 rotates while always maintaining tension, the crushing force is improved.

  In the crusher 1 in operation, the object is crushed when the chain 4 collides. However, depending on the impact force, such as when the strength of the object is stronger than the impact force, the object has elasticity, or the object is lightweight and does not generate sufficient impact force, When not destroyed, the object is not crushed, and the shaft 4 continues to rotate by avoiding the object by bending and bending the chain 4 or by avoiding the chain 4 by the object. The result of the collision between the chain 4 and the object includes not only such crushing and non-crushing, but also partial crushing of only a fragile portion of the object, fine crushing and cutting of a brittle object. The object is sent from the upstream to the downstream by continuous hitting by the spiral chain 4 while being subjected to such crushing, partial crushing, crushing, cutting, or non-crushing.

  The effect of the crusher 1 by Example 1 of this invention is demonstrated. In the crusher 1, the material of the chain 4, where crushing, partial crushing, crushing, cutting, or non-crushing occurs due to the relationship between the strength of the chain 4 and the object, elasticity, impact force, and the like as described above. By adjusting the weight, the bending length, the rotational speed of the shaft 2, etc., it is possible to generate material selectivity that selects only a desired object from the mixed objects and crushes the object. become.

  Since the chain 4 is formed in a spiral shape, the object is continuously hit not only outside the radius of rotation but also in the direction of the rotation axis, and the feed force in the axial direction of the object only by driving the shaft 2. Will be generated naturally. Thereby, even if the apparatus is placed horizontally and the shaft 2 is provided horizontally, the object is automatically moved and discharged toward the downstream in the rotation axis direction, so that the object continues to rotate at the same place. There is nothing, and the crushing efficiency can be improved. In addition, by automatically generating the output of the object, the entire apparatus can be reduced in size and the burden of human labor can be reduced. Configuring the chain 4 in a spiral shape can also prevent dead space due to the rotation of the chain and improve crushing efficiency. Further, if a chain 4 having a corner is used, the peeling function can be improved or a cutting force can be applied.

  By attaching the shaft 2 and the chain 4 via the rotary disk 3, the chain 4 can be easily fixed, and the mounting accuracy can be improved. As a result, the chain 4 can be easily attached and detached, and maintenance such as changing the material, weight, and bending length of the chain 4 and exchanging a partially damaged portion is facilitated.

  For example, when the target object is a soil wall of a demolished house, a fragile lump is crushed and crushed by collision with the chain 4, while firewood, bamboo, wood pieces, etc. are not crushed by receiving a collision force, and these are easily It can be separated and collected. The lump stuck to the fence, bamboo and wood pieces is also crushed by the collision with the chain 4, and the separation accuracy becomes very good.

  Also, for example, when the target object is waste gypsum board, the gypsum component of the core material is crushed and crushed by collision with the chain 4, but the paper on the surface is folded but recovered without being almost torn or cut. can do. Since the gypsum component stuck to the paper can be scraped off by the collision with the chain 4 and peeled off, almost only the paper can be easily recovered.

  The material selectivity of the crusher 1 according to the present invention has a very wide range of applications. For example, even if the same chain 4 as that used for crushing the earth wall is used, the empty can of drinking water is kept almost in its original form. It can be sent as it is. Therefore, the crusher 1 can be applied to a very wide variety of objects by utilizing such material selectivity. For example, in addition to the earth wall and waste gypsum board, it is possible to peel only the label without breaking the glass bottle, or peel the skin without damaging the vegetables and fruits. In addition, waste mixtures containing hazardous chemical substances, which have become a subject of recycling in recent years, can be collected separately using differences in physical properties such as strength and elasticity. Furthermore, it is useful not only for waste but also for refining raw materials at the manufacturing site by making use of the output of the object naturally generated by the above-described spiral structure.

  Since the chain 4 is allowed to bend even when the crusher 1 is in operation, the shaft 2 can be used vertically or horizontally, and can be arbitrarily selected according to the installation space and the object. The crusher 1 is first assumed to be fixedly installed in a housing as shown in the second embodiment. However, the crusher 1 is not limited to this, and can be installed in a general-purpose container such as a drum can. A member can be provided and it can also be set as a simple crusher.

  Since the crusher 1 has a simple structure, the crusher 1 can be manufactured at a low cost, is less damaged, has a light human labor burden as described above, and is easy to maintain, so that all costs can be suppressed.

  A crusher 201 which is a preferred embodiment 2 of the present invention will be described below with reference to FIGS. As shown in FIG. 4, the crusher 201 is provided with a casing 250 around the crusher 1 of the first embodiment. The crusher 201 according to the present embodiment is in common with the crusher 1 of the first embodiment in which the part number is in the 200s, and the description uses this.

  The housing 250 has an inlet 251 and an outlet 252 and supports the shaft 220 so as to be rotatable inside.

  The object to be crushed input from the inlet 251 is subjected to crushing, partial crushing, crushing, cutting, or non-crushing by the chain 240 in the housing 250, and from upstream to downstream (left side to right side in FIG. 4). Are sent out. At this time, the object is sent out while being bounced off the outer side of the rotation, that is, toward the inner edge of the casing 250 by the inertial force received from the rotation of the chain 240, so that the rotating disk 230 does not become an obstacle to the sending.

  Due to the helical structure of the chain 240, as long as the shaft 220 rotates in the same direction, the delivery direction of the object is constant. In other words, if the shaft 220 is rotated in the reverse direction, the delivery direction of the object can be reversed. It can be done. FIG. 5 shows a case where the same crusher 1 as in Example 1 is used and is rotated in the reverse direction to FIG. At this time, the input port 251 and the discharge port 252 are on the opposite side of FIG.

  Since the chain 240 rotates spirally, the dead space between the rotation radius of the chain 240 and the inner edge of the housing 250 can be reduced. It is necessary to provide a clearance between the turning radius of the chain 240 and the inner edge of the housing 250 so as not to interfere with each other. However, the shaft 4 and the chain 4 can be fixed by fixing the chain 4 via the rotating disk 3. Since the mounting accuracy can be improved, the clearance can be reduced and the pulverization accuracy can be improved. Further, if this clearance is reduced, even when the shaft 220 is set vertically, that is, when the crusher 201 is used in a vertical position, the object travels along the inner edge of the casing 250 and falls without being crushed. Can be reduced.

  A crusher 301 that is a preferred embodiment 3 of the present invention will be described below with reference to FIGS. The crusher 301 is provided with a sieve body 360 around the crusher 1 of Example 1 as shown in FIG. In order to prevent scattering of crushed materials, a casing 350 is provided in the same manner as in the second embodiment, but this is not shown in the figure. The crusher 301 according to the present embodiment is in common with the crusher 1 of the first embodiment in which the part number is in the 300s, and the description uses this.

  The sieve body 360 has a cylindrical shape having a net-like structure provided inside the casing 350 and outside the rotation radius of the chain 340. The casing 350 is provided with an under-sieving outlet (not shown) for discharging the object after being crushed by the chain 340 and sieved by the sieve body 360. In FIG. 6, in order to efficiently pulverize an object that falls due to gravity, a shaft 320 is provided eccentrically downward with respect to the sieve body 360, but the rotation radius of the chain 340 with respect to the cylindrical radius of the sieve body 360. Can be coaxial.

  As shown in FIG. 7, when the sieve body 360 is provided, the delivery direction can be reversed by reverse rotation. At this time, attention is paid to a change in the radius of rotation of the chain 340.

  The sieve body 360 is not necessarily cylindrical, and as shown in FIG. 8, a cylindrical sieve body 360 may be provided only at the lower portion to screen the object to be dropped. In the case shown in FIG. 6, the sieve body 360 has a cylindrical shape around the entire circumference in order to efficiently screen the object crushed by the chain 340 and jumped out by the impact. Space can be achieved.

  A plurality of crushers 301 can be stacked one above the other so as to sort out sieves having different particle sizes. That is, the upper stage is roughly crushed by a crusher 301 using a chain 340 made of a large-diameter steel shaft, and the lower sieve of the object having a large particle size obtained by the upper stage sieve body 360 is smaller than the lower stage. An object having a small and uniform particle size can be obtained by a lower sieve body 360 by crushing and crushing with a crusher 301 using a chain 340 made of a steel shaft.

  The embodiment of the present invention is not limited to the above embodiment, and all the configurations described in the above embodiment are not necessarily essential elements of the present invention. The present invention may take various modifications and the like within the technical scope without departing from the technical idea thereof.

  The crusher according to the present invention can selectively perform crushing, crushing, and peeling depending on the material, and can perform sieve selection in combination with a sieve. The target is assumed to be separate collection of waste, but is not limited to this, and can be applied to various things such as purification of manufacturing raw materials by utilizing the characteristics of the present invention.
