Description

  The present invention relates to a vertical impact crusher. More specifically, the present invention relates to a vertical impact crusher that collides a raw material such as concrete waste with an impacting body that rotates at high speed and an anvil fixed around the impacting body.

  Natural rocks, concrete wastes, etc. are used according to various applications as artificially crushed crushed materials. In particular, many are reused in the civil engineering and construction fields. When road repairs and buildings are dismantled, a lot of various industrial wastes such as asphalt glass and concrete waste are discharged. Therefore, it is often reprocessed and reused. The treatment method for this purpose is mainly crushing treatment, but many crushing devices have been proposed. Various crushing methods and apparatuses are known, and a vertical impact crusher is an example.

  In this regard, the present applicant has also proposed vertical impact crushers with various configurations (see, for example, Patent Documents 1, 2, and 3). This vertical impact crusher uses a vertical rotor with acceleration blades to rotate raw materials such as rock and concrete waste at high speed, accelerates the raw materials with the blades, and puts them on the outer periphery of the blades. The principle is that the collision is made by colliding with the arranged collision object. This vertical impact crusher is mainly divided into an anvil method and a dead stock method due to the difference in the crushing method.

  The anvil type vertical impact crusher rotates the rotor at high speed, accelerates the raw material on the rotor put into the housing by rotation, and makes it collide with an anvil fixed around the rotor by centrifugal force. It is to be crushed. This anvil type vertical impact crusher is mainly used for the purpose of crushing the raw material in a small size.

  On the other hand, the dead stock type vertical impact crusher is mainly used for smoothing the surface of a crushed material already crushed to a desired size and adjusting the particle size. This dead stock type vertical impact crusher is the same as the anvil method in that the raw material is accelerated by the rotor, but the dead stock is formed by the crushed material around the rotor. The raw material collides with the surface in a rolling manner, and the raw material is crushed and shaped.

  Explaining the structure of the anvil system, in the current vertical impact crusher, a plurality of anvils are formed in an annular shape on the inner peripheral wall surface of the crushing chamber, which is an internal space in the housing formed in a square shape in a square shape. The raw material which is disposed and is released at high speed by centrifugal force on the rotor rotating at high speed is received by this anvil and collided to be crushed. These anvils have extremely high wear resistance and are made of, for example, high chromium cast steel. Although it is a member having extremely high hardness and wear resistance, since it is frequently used, wear and breakage occur during the use process.

  For this reason, these anvils must be replaced periodically if they exceed the wear limit. This anvil replacement is usually performed from the top of the housing. Since the anvil is heavy, it is generally removed individually or divided and replaced with a new anvil. In the case of dead stock, since the crushing raw material has a stuck surface or a laminated surface as a collision surface, proper maintenance and renewal are required as a crushing surface.

  As an example of replacement of these anvils, the anvil support frame can be integrally removed from the housing, and the anvil support frame can be easily fixed at the time of installation so that the anvils can be replaced collectively. A crusher is known (see, for example, Patent Document 1). In addition, in the case of the dead stock type, a configuration in which a rotor guide portion is provided that gradually decreases the blade height from the central region of the rotor to the outer peripheral edge so as to match the movement of the raw material. There are known crushers such as wings disposed at equal angular positions and having dead stock on the wings (see, for example, Patent Documents 2 and 3).

  As yet another example, a crusher configured to provide a bottomed rotating cylinder at the center of rotation, discharge the raw material into the discharge space from the raw material discharge gap on the side of this cylinder, and crush the raw material by colliding with the rotating striker Is known (see, for example, Patent Document 4). Further, an impact crusher having a configuration in which a cylindrical repellent plate can be exchanged in a divided form is also known (see, for example, Patent Document 5).

WO2009 / 044731 A1 Publication JP 2002-159872 A JP 2003-181314 A Japanese Patent Publication No.58-10142 Japanese Utility Model Publication No. 5-9646

  When the crushing operation is performed by a crusher, particularly when the crushing operation is performed by colliding with high speed rotation, the raw materials such as rocks and concrete waste materials are pulverized with crushing. In some cases, the particle size is small and may become turbid with air as it rotates. Criteria related to this crushing are defined by JIS (Japanese Industrial Standard), and usually crushing is performed according to this standard so as to have a constant particle size distribution. However, in general, the striking structure is limited, so it may not always be as ideal. When the particle size is coarse, there is a case where the material is not crushed by a single hit and the material must be crushed again.

  On the other hand, a striker and an anvil are members that are constantly subjected to a collision of raw materials. Even a member with increased hardness cannot completely prevent wear. Further, conventional crushing has been centered on crushing by a single crusher with a striker or anvil. For this reason, if the crushing is performed only once, the crushing ability is inevitably limited, and there is a limit to improving the crushing efficiency. For this reason, it is often necessary to select a raw material to be applied.

  In addition, crushed materials such as dust are stuck in the housing, and wear of the striker and the anvil is unavoidable, which reduces the crushing efficiency, but cannot be easily separated during operation. For this reason, due to the occurrence of wear of the striker and the anvil, the work of replacing the striker and the anvil must be performed, and maintenance is indispensable. A crusher having a configuration that is easy to maintain improves the crushing work because it can be restarted quickly. The technique disclosed in the above-mentioned patent document has both advantages and disadvantages for simultaneously improving the crushing efficiency and maintenance efficiency, and it has been difficult to satisfy both.

Thus, the crusher is required to have further crushing efficiency, and a crusher having a structure that is easy to maintain has been desired. The present invention was created to solve the above-described problems and achieves the following object.
An object of the present invention is to provide a vertical collision type crusher that improves crushing efficiency and enables finer crushing. Another object of the present invention is to provide a vertical collision crusher that facilitates maintenance.

The present invention takes the following means in order to achieve the object.

In the guide member (16), three or four wing bodies (16a) are arranged at equal angular intervals on the circular vertical rotating body (10), and both circumferential surfaces of the wing body (16a) are arranged. The accelerating guide surface (16b) is provided on the outer periphery of the outer peripheral surface having a space where the object to be crushed can be retained. It is characterized by being.

  The vertical impact crusher of the present invention 2 is characterized in that, in the present invention 1, the anvil (21) is a rectangular plate-like body.

The vertical impact crusher of the present invention 3 is the present invention 1 or 2,
On the circular vertical rotating body (10), a second striking body (30) for rebounding and colliding the object to be crushed by colliding with the striking body (17) by rebounding is provided on the striking body (17). It is characterized by being placed between them.

The vertical impact crusher of the present invention 5 is the present invention 1 or 2,
The guide member (16) is capable of rotating by a predetermined angle in an angular direction relative to the circular vertical rotating body (10) and being capable of angular deviation.

  In the vertical impact crusher of the present invention, the raw material guided from the guide member on the rotor is crushed by the impacting body that rotates in the same manner, and is crushed by the anvil disposed in the housing. It was possible to finely pulverize and reduce the particle size, and to improve the crushing efficiency of the raw material. In addition, since the striking body itself can be adjusted to the optimum striking position, the crushing is effective. Furthermore, since the anvil is configured to be able to be removed from the housing at the same time or partially as a whole, the anvil has become a crusher having a configuration that facilitates maintenance such as anvil replacement.

FIG. 1 is a cross-sectional view showing the overall configuration of an embodiment of a vertical impact crusher of the present invention. FIG. 2 is a plan view showing the overall configuration of the vertical impact crusher according to the embodiment of the present invention, and is a cross-sectional view taken along the line AA of FIG. FIG. 3 is a plan view showing a configuration of a guide body in which three wing bodies and three impact bodies are arranged. FIG. 4 is a plan view showing a configuration of a guide body in which four wing bodies and impact bodies are arranged. FIG. 5 is a cross-sectional view taken along the line BB in FIG. FIG. 6 is a cross-sectional view taken along the line CC of FIG. FIG. 7 is a plan view of the guide body showing a worn state of the impacting body. FIG. 8 is a plan view of a guide body showing another example in which a second impacting body is provided.

  Embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 are general views showing the overall configuration of the present invention, FIG. 1 is a longitudinal sectional view thereof, and FIG. 2 is a plan view of the sectional view taken along the line AA of FIG. The housing 1 generally includes a housing main body 2 and a lid body 3 that is detachably fixed to an upper portion of the housing 1 via a stopper. The lid 3 is for blocking the upper part of the housing 1 and preventing scattering when the raw material is crushed.

  One end (tip) of a lever 4 that swings up and down is connected to the center of the lid 3 via a support shaft. The other end (base end) of the lever 4 is slidably connected to a pedestal fixed to the side surface of the housing body 2 by a pivot shaft 5. A tip end of a piston rod of the hydraulic cylinder 6 is pivotally connected to an intermediate portion in the longitudinal direction of the lever 4 by a shaft (not shown). The base end that supports the hydraulic cylinder 6 is connected to a pedestal that is the same member as the support member of the pivot shaft 5 so as to be swingable by a shaft in the vertical direction. Therefore, the lid 3 is moved up and down by the drive operation of the hydraulic cylinder 6 and simultaneously swings by the lever 4 that pivots around the pivot shaft 5 to open and close the upper portion of the housing body 2.

  The central part of the lid 3 is opened in the vertical direction, and this opening constitutes a raw material charging port 7. An upper guide chute 8 a for guiding the charged raw material is provided below the charging port 7. And a lower guide chute 8b are fixed to the lid body 3 and fixed in a two-stage configuration. The upper guide chute 8a has a funnel-like shape for guiding the charged raw material, and has a circular shape with a downwardly sharpened cone. The upper guide chute 8a is fixedly disposed at the lowermost portion of the insertion port 7. Further, the lower guide chute 8b has a funnel-like shape, and has a circular shape with a pointed downward cone. The lower guide chute 8b is fixed to the lower ends of a plurality of vertical ribs 3a that form a part of the base body of the lid 3.

  Further, a rotating rotor is disposed below the lower guide chute 8b, and a guide body 9 is disposed at the center and at the upper portion of the rotor. The guide body 9 is fixedly disposed at the upper end of the vertical (vertical) rotating shaft 10. The guide body 9 is for guiding the raw material in order to accelerate the discharged raw material and discharge it from the outer periphery. The vertical rotating shaft 10 is rotatably supported by the shaft housing 11 via a bearing (not shown). The shaft housing 11 is supported and fixed to the central portion of the housing body 2 via a plate-like bracket 12. The pulley 13 is fixed to the lower end of the vertical rotating shaft 10 and is driven to rotate by an electric motor (not shown).

  The electric motor capable of rotating in the forward and reverse directions rotates the vertical rotation shaft 10 via the pulley 13 and the V-belt or the like, and as a result, the guide body 9 disposed on the rotor can be rotated in the forward and reverse directions. The guide body 9 includes a vertical rotating shaft 10, a rotor body 14, a distribution plate 15, a guide member 16, a striking body 17, a liner 18, and the like. The rotor body 14 is fixed to the vertical rotating shaft 10 integral with the shaft housing 11 and has a thick disk shape. The distribution plate 15 is arranged and fixed at the center of the upper surface of the rotor body 14, and is formed with a circular taper with a sharp upper part. The raw material is dropped on this tapered surface and rolled on that surface. Thus, the raw material is accelerated and dispersed in the radial direction of the guide body 9.

  The guide member 16 is composed of a plurality of wing bodies 16a, and is three wing-like members provided at equal angular intervals in the circumferential direction of the outer peripheral portion of the distribution plate 15 (see FIG. 2). The liner 18 on the rotor body 14 prevents wear on the outer surface of the rotor body 14 and is detachably fixed to the rotor body 14 by a known fixing means such as a bolt so that it can be replaced when worn. It has been done. That is, the liner 18 is an exchange member made of wear-resistant metal or the like disposed so as to cover the upper surface and the outer peripheral surface of the outer periphery of the rotor body 14.

  On the liner 18, three striking bodies 17 are fixed to the rotor body 14 so as to be spaced apart from the outer periphery of the guide member 16 and at equal angular intervals. However, the fixing angle position can be changed by loosening the bolt fixing the impacting body 17. Therefore, the impacting body 17 rotates together with the guide member 16 as the rotor body 14 rotates. In this embodiment, the housing 1 is a regular rectangular cylinder, and a protective liner is provided on the inner surface. A dead stock forming plate 19 is disposed on the outer periphery of the rotor body 14 inside the housing 1.

  The dead stock forming plate 19 is formed of a regular tetragonal plate similar to the cross-sectional shape of the housing 1, and its peripheral edge is fixed to the intermediate portion of the housing body 2. The dead stock forming plate 19 has a circular hole 20 having a diameter larger than that of the rotor body 14 and concentric with the rotation center line of the guide body 9. A part of the dead stock forming plate 19 also serves as a member that supports and positions the anvil support frame 22 that is a support member of the anvil 21. The crusher of the present embodiment has a configuration that combines the two functions of the dead stock method and the anvil method described above.

  Next, the configuration and function of the guide body 9 will be described. In FIG. 2, the configuration of the guide body 9 is illustrated in the case where three arcuate wing bodies 16a that are the guide members 16 are arranged, but the configuration of the four wing bodies 16a is also illustrated. Good. FIG. 3 is a plan view showing a configuration of the guide body 9 in which three wing bodies 16a and three impact bodies 17 are equally arranged, and FIG. 4 shows four wing bodies 16a and four impact bodies 17 equally. FIG. 3 and FIG. 4 are explanatory views showing an example in which the rotation directions of the wing body 16a and the impacting body 17 are forward and reverse. 5 shows a cross-sectional view taken along the line BB of FIG. 4, and FIG. 6 partially shows a cross-sectional view taken along the line CC of FIG.

  In FIG. 1, when the raw material is input from the input port 7 of the housing 1, the raw material falls on the circular plate 15 of the guide body 9. As described above, the guide body 9 has the rotor body 14 integrally fixed to the upper end of the vertical rotation shaft 10, and the distribution plate 15 and the liner 18 are fixed on the rotor body 14. Further, a guide member 16 is disposed on the outer periphery of the distribution plate 15 on the liner 18. The guide member 16 is composed of three wing bodies 16a arranged at equiangular intervals, and the wing body 16a of the present example has a fan shape in plan view. Further, three striking bodies 17 are arranged apart from the outer periphery of the guide member 16 and on the liner 18.

  For this purpose, the dropped raw material is dispersed by the distribution plate 15 and discharged toward the circumferential direction as shown by an arrow D (see FIGS. 3, 4, and 5) and contacts the guide member 16. The distribution plate 15 has a tapered surface whose peripheral portion is inclined from the center toward the outer periphery, and has a structure in which the raw material is easily dispersed on the guide member 16 side. Each arcuate wing body 16a of the guide member 16 is provided with a guide surface 16b which is a plane substantially parallel to the radial direction and which is a vertical surface. When there are three wing bodies 16, there are six guide surfaces 16b. Since the guide body 9 rotates at a high speed, the raw material is accelerated in the circumferential direction along the guide surface 16b and discharged outward. However, in actual crushing, three guide surfaces 16b in one direction of the rotor are used, and the other three guide surfaces 16b for reversing the rotor are used.

  Each wing body 16a has a concave shape 16c on the inner wall on the distribution plate 15 side, and a part of the raw material stays in the concave shape 16c to constitute a dead stock 16d with sticking. For this reason, since the raw material input from the input port 7 is guided to the guide surface 16b while being in contact with the dead stock 16d, that is, rolling, the acceleration performance is further increased. By configuring the dead stock 16d, the raw material is accelerated and released stably.

  As described above, the impacting body 17 is disposed on the liner 18 away from the outer peripheral surface of the wing body 16a. The striking bodies 17 are disposed at equiangular intervals along the radial direction and at positions slightly spaced from the outer periphery of the arcuate wing body 16a. The striking body 17 is made of a hard metal material, and the side wall surface forms a striking surface 17a on which the raw material collides and is crushed. The striking body 17 is supported by a support shaft 17 b fixed to the rotor body 14, and is disposed on the liner 18.

  The raw material accelerated by the guide surface 16b is discharged into the discharge space 18a on the liner 18 and collides with the striking surface 17a of the striking body 17 along the flow direction indicated by the arrow (see FIG. 3). The material is crushed by this collision. The basic principle that the raw material is crushed by drawing a parabola is well known in the above-mentioned patent documents and the like, and detailed description thereof is omitted here.

  As shown in the figure, this crushing becomes a crushing trajectory by the arrow X1 when the guide body 9 is in the rotational direction indicated by X. Since the guide body 9 can rotate in either the forward direction or the reverse direction, in the reverse direction of X, that is, in the rotational direction indicated by Y, a crushing trajectory is formed by the arrow Y1. By rotating in the forward or reverse direction in this way, the wear of the impacting body 17 is equalized, and it is avoided that the wear is biased to one side.

  FIG. 7 shows a state in which the position of the impacting body 17 according to the first embodiment can be shifted by a predetermined angle amount relative to the liner 18 to shift the position. The striking body 17 is worn as the operation is repeated, and the striking surface 17a is worn down to become a wearing surface 17c. For this reason, a striking position shifts with respect to the guide surface 16b, and a shift occurs in the striking direction compared to the beginning.

  As one means for solving this, the angular position is shifted by swinging the impacting body 17 in the angular direction about the support shaft 17b with respect to the initial position indicated by a two-dot chain line. Thereby, since the striking surface 17a becomes a direction approaching the discharge direction, an effective striking range can be secured even if the striking surface 17a is worn. When worn, the center of gravity of the impacting body 17 changes and automatically comes to an appropriate angular position. That is, the angular position is such that the center of gravity is located at a radial position from the center line of the support shaft 17b.

[Second Embodiment]
4 to 6 show the structure of a guide body in which four wing bodies and striking bodies are arranged, FIG. 4 is a plan view, and FIG. 5 is a sectional view taken along the line BB in FIG. FIG. 6 shows the configuration of the impacting body in the CC cross-sectional view of FIG. The guide body 9 is configured such that the position of the wing body 16a can be rotated by 45 degrees in the rotation direction with respect to the rotor body 14. As shown in the partial cross-sectional views of FIGS. 4 and 5, a convex portion 16 e is provided at the lower portion of the wing body 16 a, and the convex portion 16 e is fitted into the concave portion 14 a provided in the rotor body 14, so that the operating range is 45. Regulated to a range of degrees.

  The distribution plate 15, each wing body 16 a, and the convex portion 16 e integrated with the wing body 16 a are integral, and can be swung within a range of 45 degrees around the center line of the vertical rotation shaft 10. (See FIG. 5). This swing may be fixed by a fixing means such as a bolt at an arbitrary angular position, or may be freely rotated. That is, the wing body 16a can be angularly displaced in the rotational direction relative to the rotor body 14 within the recess 14a within a range of 45 degrees. In other words, the convex portion 16e and the concave portion 14a function as a stopper. By adjusting the angle while the blade body 16a is operating or stopped in this way, the blade body 16a can be rotated by 45 degrees more than usual, so that the discharge gap and discharge curve of the raw material can be adjusted.

  6 is a cross-sectional view taken along the line CC of FIG. The striking body 17 is fixedly supported by meshing with the liner 18 via a groove 18b by a support body 17b made of a bolt or the like fixed to the rotor body 14 on the liner 18. As shown in FIG. 1, the upper part in the housing 1 has a space 2a. A space 2b is formed between the upper guide chute 8a and the lower guide chute 8b.

  The raw material that has been crushed and soared upward can pass through the space 2b while circulating through the space 2a as shown by the arrows in FIG. Thereby, the raw material crushed in the initial stage can be guided to the guide body 9 again. By doing in this way, a raw material can be grind | pulverized further finely.

  FIG. 8 shows another embodiment of the guide body 9 in which a second impacting body 30 is provided on the liner 18 to give a collision operation when the material colliding with the impacting body 17 rebounds. . The second impacting body 30 is disposed at an intermediate position between the two impacting bodies 17. The raw material collided by the impacting body 17 can be made to collide with the second impacting body 30 as shown by an arrow in the rebound of the impact.

  Although all the raw materials cannot collide with the second impact body 30 and be crushed, it is effective for finely pulverizing the raw materials. The raw material released from the guide body 9 configured in this way collides with the impacting body 17 and further collides with the anvil 21 fixed to the inner wall of the housing body 2 and is further crushed. Next, the mounting configuration of the anvil 21 will be described.

  The anvil 21 is made of a rectangular plate material, and a handle for attaching and detaching is formed on the upper part thereof. The anvil 21 is detachably attached to the anvil support frame 22, and the anvil support frame 22 is detachably attached to the dead stock forming plate 19. A plurality of anvils 21 are attached to the anvil support frame 22. As shown in FIG. 2, a plurality of anvils 21 are arranged radially (radius method) on the outer periphery of the guide body 9 so as to surround the outer periphery of the guide body 9.

  Each anvil 21 is detachably supported by an anvil support frame 22. The dead stock forming plate 19 is configured as a member that enables the dead stock 19a (see FIG. 1) to be formed on the inner wall of the housing 1. The anvil support frame 22 is composed of a plate-like member that is two upper and lower annular plates, and is configured to support the anvil 21 with a pair of upper and lower frame plates, that is, an upper frame plate 23 and a lower frame plate 24. . Central portions of the upper frame plate 23 and the lower frame plate 24 form a circular hole and serve as a material recovery hole.

  The upper frame plate 23 is provided with a plurality of holding hole grooves 25 (see FIG. 1) along the circumferential direction, and the anvils 21 are inserted into the holding hole grooves 25 from above. On the other hand, the lower frame plate 24 is provided with a support groove for positioning and supporting the lower portion of the anvil 21. The lower frame plate 24 supports the lower part of the anvil 21 in a state of being inserted into this support groove (not shown). Since the anvil 21 has a rectangular parallelepiped shape, when it is worn from one side, the upper and lower sides or the upper and lower sides of the other side are evenly changed by simply turning the front and rear and the vertical direction to the rotor side. This can save resources.

  The upper and lower pair of upper frame plate 23 and lower frame plate 24 are fixed by sandwiching four places with support pillars (not shown). That is, the upper frame plate 23 and the lower frame plate 24, which are upper and lower frame plates, are screwed and integrated with each other via a support column. In addition, this support column is provided with prevention walls on both sides in order to prevent a direct collision of raw materials due to hitting during crushing. Thus, the anvil 21 is installed in a state in which the upper part is inserted into the holding hole groove 25 and the lower part is inserted into the support groove and regulated. Further, the anvil 21 is a substantially rectangular plate material and is symmetrical in the longitudinal direction. Furthermore, a fixing plate 26 for attaching the anvil support frame 22 to the housing body 2 is provided on the lower frame plate 24 below the anvil support frame 22.

  The fixing plate 26 is provided with a slip prevention member for fixing the anvil support frame 22 to the mounting portion of the housing body 2, that is, the dead stock forming plate 19 in an accurate position. The fixing plate 26 and the dead stock forming plate 19 are provided with bolt holes. When the anvil support frame 22 is inserted into the housing body 2 from the outside and attached, the fixing plate 26 and the dead stock forming plate 19 are positioned so that the bolt holes are aligned. When they coincide with each other, the fixing plate 26 and the dead stock forming plate 19 are overlapped and fixed with bolts 27 from between the outer ribs of the housing body 2.

  As shown in the figure, the anvil 21 is a rectangular body having a rectangular cross section and a predetermined length. When the anvil is taken out of the housing during maintenance, the bolt 27 is removed, and the set can be taken out while being supported by the support frame. As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment. Needless to say, changes can be made without departing from the scope and spirit of the present invention. For example, although the anvil is described as a rectangular shape as a collision body, a repellent plate configuration may be used, and the shape is not limited thereto.
