Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vertical crusher for crushing an object to be treated such as industrial waste to a predetermined size, and particularly for finely crushing waste plastic such as polyvinyl chloride or FRP to a predetermined size. The present invention relates to a suitable vertical crusher and a crushing method thereof.
[0002]
[Prior art]
BACKGROUND ART Conventionally, industrial waste such as waste plastic has been landfilled at a landfill site or the like. However, due to problems such as an increase in the amount of waste and a decrease in the number of treatment sites, there is a tendency to collect recyclable waste in order to reuse effective resources of industrial waste. As a method for recovering the effective resources from the industrial waste, there is a method in which the waste is crushed to facilitate the handling and treatment of the crushed material to be processed and then sorted and recovered.
[0003]
On the other hand, in recent years, waste plastic has been regarded as important as a material to be crushed in this way. Waste plastics include various plastics used for various products such as home appliances and industrial products, and there are also plastics such as polyvinyl chloride and FRP. There are many composite materials in which physical plastics are joined. Hereinafter, this waste plastic will be described as an example of the object to be treated.
[0004]
Since such waste plastics cause great environmental destruction due to waste treatment, recycling of the waste plastics is urgently required. As a method of recycling waste plastic, generally, there are a material recycling for recycling as a new raw material and a thermal recycling for recovering as heat energy.
[0005]
In the material recycling, waste plastics are separated by physical properties and mixed with a virgin material, or used as a raw material for new recycled plastics. In the thermal recycling, heat is recovered by incineration or solid fuel is used.
[0006]
In addition, as a crusher for crushing the object to be treated such as industrial waste as described above, the object to be treated introduced from the top is crushed by a crusher disposed between blades provided in a stepped manner. There is a vertical crusher (for example, see Patent Document 1).
[0007]
[Patent Document 1]
JP-A-8-24684 (FIG. 1)
[0008]
[Problems to be solved by the invention]
By the way, as mentioned above, in order to materially or thermally recycle waste plastics generally used as a composite material, it is necessary to separate plastics from integrally bonded metals or the like or to use plastics having different physical properties. And plastic must be separated according to their physical properties.
[0009]
Generally, specific gravity separation and electrostatic separation are known as methods for separating plastic. In the specific gravity separation, for example, a vibration table is used to perform separation based on a difference in specific gravity of a substance. In addition, electrostatic separation, by stirring different types of substances, the rubbed substances, one surface is positive, utilizing the triboelectric charging characteristics that the other surface is negative, for example, In some cases, a negatively charged plastic is adsorbed on a positive electrode to separate it from the positively charged plastic.
[0010]
However, in order to efficiently separate plastics having different physical properties by such a separation method, efficient separation cannot be achieved unless the size (size) of the waste plastic is fixed to some extent. In other words, in the case of specific gravity separation, a weight difference depending on the size affects separation, and in the case of electrostatic separation, a charge amount difference depending on the size affects separation, thereby hindering efficient separation. Therefore, it is necessary to make the size of the object to be processed fine and uniform in size in order to facilitate transportation and separate efficiently. The size of the waste plastic is preferably, for example, about 5 mm to 7 mm.
[0011]
For this reason, a crusher capable of uniformly crushing industrial waste such as waste plastic with a uniform particle size has been desired.
[0012]
The above-mentioned Patent Literature 1 is for pulverizing iron scraps, oversized garbage and the like, and is not capable of efficiently crushing an object to be treated such as waste plastic into a predetermined size.
[0013]
[Means for Solving the Problems]
Therefore, in order to solve the above problem, a vertical crusher of the present invention is provided with a plurality of rotor cutters in an outward vertical direction and a rotor that rotates around a vertical axis, and is provided inward between rotor cutters of the rotor. A cage provided with a cage cutter provided at the outer periphery of the rotor to form a crushing space between the inner periphery of the cage and the outer periphery of the rotor. An opening for discharging the processing object at a predetermined crushing size is provided, and the rotor has an object introduction section for guiding the processing object to the crushing space by wind power. As a result, the object to be treated is quickly guided to the crushing space between the outer periphery of the rotor and the inner periphery of the cage by wind power, and the object to be treated is finely crushed to a predetermined crushing size efficiently by the rotor cutter of the rotor and the cage cutter of the cage. can do. In addition, since the object is a vertical type, the residence time is long while the object is crushed to a predetermined size. During this time, the surface of the object can be effectively cleaned.
[0014]
The cage is configured to be rotatable in a direction opposite to the rotation direction of the rotor, and the relative speed between the cage and the rotor can be adjusted so that the cage cutter and the rotor cutter face each other in accordance with an object to be processed. The speed at which the object is crushed can be changed by easily changing the speed. In addition, since the centrifugal force is generated by rotating the cage, the object to be processed is concentrated so as to be attracted to the crushing space inside the cage, thereby improving the crushing efficiency, and the crushed object can be easily discharged to the outside of the cage. .
[0015]
Further, if the cage is provided with a plurality of openings, a mesh having predetermined openings is provided in the openings, and the crush size of the object to be processed is determined at the openings of the mesh, the crushing is performed by adjusting the mesh. The size can be easily changed.
[0016]
Further, the rotor is formed of a plurality of rotor members divided in the axial direction, the rotor member is formed as a polygon having a plurality of sides formed around the rotor members, and the rotor members are arranged in a circumferentially shifted manner from the upper part to the lower part. When the workpiece introduction portion is formed on the side of the rotor member by doing, the side of the rotor member locked in a polygon is shifted from the upper portion to the lower portion to form a step-like stepped portion. The object to be treated can be guided to the crushing space by generating wind power by the object introduction part formed by the step portion.
[0017]
Further, if an air washer is provided for injecting air from the outside to the inside of the cage and air is jetted from the opening of the cage to the inside by the air washer, the inner surface of the cage can be treated. Even if the object stays in close contact, the object can be moved between the rotor cutter and the cage cutter by air to be crushed.
[0018]
In addition, if the axis of the rotor and the cage are inclined at a predetermined angle and the workpiece outlet is located on the inclined side, the crushed workpiece can be machined by utilizing its own weight. It can be discharged quickly to the outside.
[0019]
Further, by providing a biting member for guiding the workpiece to the workpiece introduction section above the rotor, even a large workpiece can be relatively easily guided to the workpiece introduction section.
[0020]
On the other hand, in the crushing method of the vertical crusher of the present invention, the input object is guided to the outer periphery of the rotor by wind generated by the rotor, and the crushing space between the outer periphery of the rotor and the inner periphery of the cage. Then, the workpiece is sheared and crushed by a cutter provided in the rotor and the cage, and when the object to be sheared and crushed falls below the opening of the cage, the workpiece is discharged to the outside. As a result, the workpiece can be quickly guided to the crushing space between the outer periphery of the rotor and the inner circumference of the cage by wind power, and the crushed workpiece can be quickly discharged from the opening of the cage to perform efficient crushing. .
[0021]
Further, if air is jetted at predetermined intervals from the outside of the cage toward the inside crushing space to move the object inside the cage toward the rotor side so as to be sheared and crushed, the object to be processed is exposed to the inner surface of the cage. Air can be effectively prevented from staying without being crushed in close contact with the air.
[0022]

That is, the rotor members 11 having a substantially triangular shape are arranged in a spiral step shape. The upper end of the rotor member 11 is fixed to the rotor shaft 4 by a rotor member presser 13.
[0027]
By arranging the rotor member 11 in this manner, the rotor member 11 composed of ten sheets is shifted by 100 degrees in the seed direction at the upper end and the lower end. It should be noted that the number of divisions of the rotor member 11 is merely an example, and may be several or integral. The rotor member 11 may have a pentagonal shape other than the substantially triangular shape, and is not limited to the substantially triangular shape.
[0028]
By disposing the rotor member 11 at a predetermined angle in the circumferential direction in this manner, a step-shaped oblique side portion is formed below the rotor member 11 formed in a substantially triangular shape. When the rotor member 11 rotates, a wind (fluid flow) is generated in a downward outward direction at the inclined portion, and the processing object 60 is rotated by the wind force and the centrifugal force acting on the input processing object 60. It is made to concentrate on the outer periphery. The space spirally formed from the upper part to the lower part is the treatment object introduction part 14.
[0029]
The substantially triangular rotor member 11 also has a function as a cutter mount, and a rotor cutter 15 projects outward from each top. In this embodiment, the rotor cutter 15 is formed in a columnar shape having a square cross section. The distance between the top of the rotor cutter 15 and the inner surface of the cage 3 is appropriately set according to the size of the workpiece 60 and the crush size.
[0030]
Further, in this embodiment, a biting member 16 for biting the workpiece 60 into the workpiece introduction portion 14 is provided at a predetermined position of the uppermost rotor member 11. The biting member 16 is erected toward the rotation side like a claw that guides the workpiece 60 from the vicinity of one top of the triangular rotor member 11 toward the workpiece introduction section 14. ing. A balance weight 17 for weight balance is provided on the top of the rotor member 11 other than the one where the biting member 16 is provided, toward the rotation front. By providing the biting member 16, even the large workpiece 60 can be relatively easily guided to the workpiece introduction unit 14.
[0031]
The rotor 2 is configured to be rotated by a motor 21 that drives a pulley 18 provided at a lower end of the rotor shaft 4 via a belt 19 and a driving pulley 20. The motor 21 is supported by a support 22 extending from the gantry 8.
[0032]
As shown in detail in FIGS. 4 and 5, a cylindrical cage frame 23 having a predetermined opening 24 is provided at an upper portion of the cage frame 9 of the cage 3. A net 25 having a predetermined opening 26 is attached to an opening 24 of the cage frame 23 with an attachment frame 27. These openings 24 and net 25 are provided on almost the entire surface of the cage frame 23. 28 is a mounting bolt. By providing the mesh 25 having the predetermined opening 26 in the cage 3 as described above, the size of the workpiece 60 discharged according to the size of the opening 26 can be determined. 60 crush sizes can be easily changed.
[0033]
In addition, as shown in these figures and FIG. 1, a support post 29 is provided at a predetermined position around the cage frame 23 (five positions in this embodiment). The support 29 is provided with a cage cutter 30 facing inward.
[0034]
This cage cutter 30 is also formed in a rectangular cross section like the rotor cutter 15. The distance between the top of the cage cutter 30 and the outer surface of the rotor 2 is also set as appropriate according to the size and crush size of the workpiece 60.
[0035]
As shown in FIG. 6, the position where the cage cutter 30 is provided is located between the rotor cutters 15 provided in the vertical direction, and passes between the rotor cutters 15 provided at predetermined intervals in a side view. In such a state, they are provided so as to almost entirely overlap in plan view. A crushing space 31 is formed between the outer periphery of the rotor where the cage cutter 30 and the rotor cutter 15 are located and the inner periphery of the cage. In this crushing space 31, shear crushing by the rotor cutter 15 and the cage cutter 30 is performed.
[0036]
As shown in FIGS. 2 and 3, a cylindrical cage guide 32 is provided above the cage frame 23. The cage guide 32 is prevented from tilting in the circumferential direction by engaging with a cylindrical engagement member 34 fixed to an upper portion of a cover 33 provided on the casing 5.
[0037]
The cage 3 is configured to be rotatable in a direction opposite to that of the rotor 2, and is rotatable by a motor 38 through a chain 36 meshing with a sprocket 35 provided at a lower portion of the cage frame 9 and a driving sprocket 37. Is configured. The motor 38 is supported by the casing 5.
[0038]
According to the rotor 2 driven at a predetermined rotation speed by the motor 21 and the cage 3 rotated in the opposite direction by a motor 38 different from the rotor 2, the relative speed is increased by rotating in opposite directions. As a result, the relative speed of the cutters 15 and 30 with respect to the workpiece 60 can be increased.
[0039]
Further, by rotating the cage 3, a centrifugal force is generated, and the object 60 is attracted to the inside of the cage 3 by the centrifugal force, so that the object 60 is concentrated in the crushing space 31 inside the cage. . Furthermore, the centrifugal force facilitates discharge of the crushed object 60 to the outside of the cage 3. The speed ratio between the rotor 2 and the cage 3 may be, for example, about 10: 1 rotor: cage.
[0040]
As shown in FIGS. 1 and 2, in this embodiment, an air washer 40 that injects air from the outside of the cage 3 toward the inside is provided. Even if the processing object 60 is stuck to the inner surface of the cage 3 due to the air cleaning machine 40, the processing object 60 is transferred to the crushing space 31 between the rotor cutter 15 and the cage cutter 30. It is moved so that it can be crushed.
[0041]
The air washer 40 includes an air pipe 41 provided in the up-down direction inside the cover 33, an air nozzle 42 provided at a predetermined interval in the up-down direction of the air pipe 41, and an inside of the cover 33. An air tube drive motor 44 for moving the air tube 41 up and down along the guide 43 is provided. The air tube drive motor 44 is configured to move the guide member 45 up and down by a predetermined amount, thereby moving the air tube 41 fixed to the guide member 45 up and down. The distance by which the guide member 45 is moved up and down by the air tube drive motor 44 is set to a distance at which air can be jetted by the air nozzle 42 in the entire vertical direction of the cage 3. By providing the air cleaning machine 40, it is possible to prevent the workpiece 60 from closely adhering to the inner surface of the cage 3 and prevent the workpiece 60 from staying in the cage cutter 30. Note that the air cleaning machine 40 may not be provided depending on the properties of the workpiece 60 and the like.
[0042]
Further, as shown in the sectional view of FIG. 3, the cover 33 is provided with a discharge port 46 for the workpiece 60 on the left side and an inspection port 47 on the right side. The discharge port 46 is provided as a part of the cover 33 so that the workpiece 60 discharged to the outside from the upper surface of the cage frame 9 of the cage 3 can be discharged. The inspection opening 47 allows the inside of the cover 33 to be inspected by opening a part thereof, and is provided with an inspection door 48. 49 is a fixed handle of the inspection door 48.
[0043]
According to the vertical crusher 1 configured as described above, when the rotor 2 and the cage 3 are rotated and the workpiece 60 is loaded from above, the workpiece 60 is formed by the rotor member 11 from above the rotor 2. It is guided to the stepped object introduction part 14 in a stepped shape. As described above, a spiral space similar to the rotor member 11 provided in a spiral staircase is formed in the processing object introduction portion 14, and the wind rotates outward to generate a wind force. Therefore, the workpiece 60 is efficiently guided from the workpiece introduction portion 14 to the crushing space 31 in the outer peripheral portion of the rotor.
[0044]
The processing object 60 guided to the crushing space 31 is sheared and crushed by the rotor cutter 15 and the cage cutter 30. If the crushing size is smaller than the opening 26 of the net 25 provided in the cage 3, the crushing of the cage 3 is performed. And is discharged from the discharge port 46 to the outside. At this time, since the crushing size is determined by the size of the opening 26 of the net 25, the workpiece 60 can be finely crushed into a uniform size. As described above, the particle size for crushing the object to be treated 60 can be uniformized to about 40 mm to several microns, preferably about 20 mm to several mm, and as described above, it can be finely divided to about 5 mm to 7 mm. Then, the specific gravity separation and the electrostatic separation can be performed relatively easily.
[0045]
At this time, the centrifugal force generated by the rotation of the cage 3 and the wind force of the rotor 2 generate wind outwardly like a blower. The processing object 60 can be quickly crushed, and the crushed processing object 60 can be quickly discharged.
[0046]
Further, even if the processing object 60 comes into close contact with the net 25 of the cage 3, the processing object 60 in a state in which the opening 26 of the net 25 is closed by being cleaned from the outside by the air of the air cleaner 40. Can be separated to the crushing space 31 side and crushed again.
[0047]
In addition, by crushing the workpiece 60 in a vertical shape, the processing object 60 has a long residence time from being thrown in from the upper portion to being discharged from the lower portion. It is preferable to remove the stain on the surface of the workpiece 60 in this manner, particularly when performing the above-described electrostatic separation, by preventing the surface from becoming unable to obtain an effective triboelectric charging characteristic. Therefore, it is preferable for the crushing of the workpiece 60 to be subjected to electrostatic separation such as waste plastic.
[0048]
In addition, the centrifugal force generated by the cage 3 and the wind generated by the rotor 2 suppress the temperature rise of the processing target 60 inside the machine, and can quickly discharge the crushed processing target 60. As in the case of thermoplastics, the workpiece 60 that melts at about 160 ° C. can be discharged without staying inside the machine.
[0049]
FIG. 7 is a side sectional view of a vertical crusher showing a second embodiment of the present invention. The second embodiment is an inclined vertical crusher, and each component is the same as that of the first embodiment described above.
[0050]
As shown in the figure, the gantry 50 for supporting the casing 5 in the second embodiment is different from that in the first embodiment. The gantry 50 includes a lower member 51 fixed on the base 7, an upper member 52 fixed to a lower portion of the casing 5 and inclined at a predetermined angle, and an inclination for maintaining the inclined state of the upper member 52. The member 53 and the member 53 are integrated. The upper member 52 is configured to be rotatable by a support shaft 54 provided on the lower member 51, and is configured to be changeable between an illustrated inclined state and a horizontal state with the inclined member 53 removed. In this embodiment, the angle is inclined at approximately 45 °, but the angle may be inclined at an optimum angle according to the properties of the workpiece 60, the crushed size, and the like.
[0051]
The cover 33 is provided such that the above-described discharge port 46 is located on the inclined side of the gantry 50. An inspection port 55 for inspecting the pulley 18 of the rotor shaft 4 and the like is provided on the opposite side of the gantry 50 from the inclined side. Since other configurations are the same, detailed description thereof is omitted.
[0052]
According to the vertical crusher 56 configured as described above, similarly to the vertical crusher 1 of the above-described first embodiment, the workpiece 60 that has been input is transferred from the workpiece introduction section 14 to the rotor 2. It is guided to the crushing space 31 between the cage and the cage 3 and is sheared and crushed by the rotor cutter 15 and the cage cutter 30.
[0053]
Then, the crushed workpiece 60 is discharged from the opening 26 of the net 25 provided in the cage 3. According to this embodiment, both the lower surface of the cage frame 9 and the lower surface of the discharge port 46 are inclined. Therefore, the workpiece 60 falls by gravity from the cage frame 9 to the discharge port 46 side, so that the workpiece 60 can be discharged more easily.
[0054]
Further, as a characteristic of the vertical crusher 56, the workpiece 60 tends to accumulate at the lower end, but by inclining the rotor 2 and the cage 3 in this manner, the workpiece 60 staying inside the cage 3 is squared. Can be collected in the department. By collecting the workpieces 60 at the corners in this manner, the workpieces 60 accumulated by the rotor cutter 15 of the rotating rotor 2 are scraped up, which is preferable for re-crushing the retained workpieces 60.
[0055]
Therefore, if the inclined type is used as in this embodiment, the object 60 stays inside as in the case of crushing the object 60 having a low specific gravity and difficult to discharge, or in the case of finer crushing. In this case, the vertical crusher 55 is preferable.
[0056]
In the above description, waste plastic has been described as an example of the processing object 60, but the processing object 60 may be other than waste plastic, and is applicable as long as the processing object 60 can be finely crushed.
[0057]
In addition, the above-described embodiment is one embodiment, and various changes can be made without departing from the spirit of the present invention, and the present invention is not limited to the above-described embodiment.
[0058]
【The invention's effect】
The present invention is implemented in the form described above, and has the following effects.
