Description

  The present invention relates to a crusher for crushing a discarded object such as an aerosol can, a spray can, and a gas lighter, and a crushed object processing apparatus including the crusher.

Gas cans used for household use, such as gas cans for tabletop stoves, ignition gas lighters, medicinal spray cans (with insecticides, etc.), paint spray cans, gas cosmetic cans (hair) Spray cans).
The biggest problem in pulverizing these gas cans is that the sparks generated when crushing the gas cans ignite the gas remaining in the gas can and explode. Such an explosion can lead to a major accident, and is an extremely important issue for the processors of these gas cans.

  For this reason, as a means to prevent this explosion, in order to hold the gas enclosed in the gas can at the time of crushing and release it to the outside, or to maintain an oxygen amount that does not explode even if the gas is released, There is a method in which air in a crushing chamber (processing chamber) is sucked to be in a low pressure state, and then nitrogen is added to increase nitrogen.

  As a method of crushing a gas can or a cylinder in the crushing chamber, a method of compressing and destroying the gas can by applying a strong pressure (press method), a method of cutting and crushing the gas can and the cylinder with a sharp blade (cutter) Cutting method).

  As a technique for crushing gas cans such as aerosol cans and spray cans, the container is sealed and then decompressed with a vacuum pump. And the technique which processes a gas can is proposed by these inventors by making a hole in a gas can etc. in the pressure-reduced process, and letting out a gas, and processing a pressure can (refer patent document 1). ).

  In the gas can processing method described in Patent Document 1, since the oxygen concentration is lowered by reducing the pressure inside the container, even if a spark occurs when the gas can is crushed, the residual gas is ignited and explodes. There was an advantage that can be prevented. In addition, since the inside of the container is only decompressed by a vacuum pump, there is an advantage that the apparatus can be downsized.

  Also, a method of cutting and processing with a rotary blade instead of crushing the can by pressure contact processing has been proposed (for example, see Patent Document 2). In this method, a plurality of sprocket gears are fixed to a pair of rotating roller shafts, and each sprocket gear attached to the pair of rotating roller shafts acts like a scissors double blade to cut gas cans. That is, the sprocket gear provided on one rotating roller shaft is arranged to be inserted between the sprocket gears of the other rotating roller shaft, and the cans inserted at the side edge of the sprocket gear are crushed. ing.

  However, among the gas cans processed by the crushing apparatus described above, there are various types such as not only different shapes but also different strengths and hardnesses of the containers. In the crushing device described in Patent Document 1, relatively large crushed objects such as aerosol cans and spray cans can be processed, but gas is obtained by reliably opening holes in relatively small crushed objects such as gas lighters. There was a problem that it was difficult to release. In addition, even when a relatively small gas product such as a gas lighter is pressure-bonded, it does not get crushed between the pressure-contact plates facing each other, that is, the gas is not released and falls as waste after processing. was there.

  Furthermore, in the crusher described in Patent Document 2, a gap is provided between the sprocket gear and the other rotating roller shaft in order to prevent the sprocket gear from being damaged. As a result, in the case of a gas lighter made of vinyl or the like, even if the gap between the sprocket gear and the rotating roller shaft is made small, the gas lighter is stretched thinly, no holes are formed, and no gas is released. was there. Here, it is conceivable to make the width of the sprocket gear and the rotating roller shaft thinner than the thickness of the gas lighter. However, if the width of the sprocket gear and the rotating roller shaft is reduced, glass bulbs that are larger than the thickness of the lighter contained in the gas can such as an aerosol can or a spray can do not enter the space between the sprocket gear and the rotating roller shaft. There was also a problem that it was impossible to do.

  The present invention has been made to solve the above-described problems, and includes not only a relatively small object to be crushed like a normal gas lighter but also a gas lighter formed of vinyl or the like or a gas can. The object is to ensure that crushed objects of different sizes, such as glass spheres, can be crushed reliably.

  In order to solve the above-mentioned problems and achieve the object of the present invention, the crusher of the present invention is arranged in a substantially parallel manner with a predetermined interval, and rotates in opposite directions so as to entrain the object to be crushed. The first and second rotating shafts, the plurality of first rotating bodies provided along the axial direction of the first rotating shaft, and the first rotation along the axial direction of the second rotating shaft. A plurality of second rotating bodies provided in a direction opposite to the direction in which the body is attached. Then, the first rotating body and the second rotating body have a plurality of crushing blades having at least one step formed on the outer periphery, a stepped portion having the same number of steps as the number of steps of the crushing blades, And when the first rotating body and the second rotating body rotate in directions opposite to each other, a part of the step surface of the crushing blade provided on the first rotating body and the second rotating body; A part of the step surface of the step portion provided in the second rotating body and the first rotating body overlaps.

  The object to be crushed according to the present invention includes a container into which an object to be crushed such as a gas can is charged, a crusher for crushing the object to be crushed, an air discharge device for discharging air contained in the container, and an inside of the container And a discharge device for discharging the residual gas generated from the crushed material crushed in the container to the outside. In addition, as a crusher, the crusher as above-mentioned is used.

  According to the crushing machine and the object to be crushed according to the present invention, a step is provided on the crushing blade and a step portion having the same number of steps as the step of the crushing blade is provided, and the two rotating bodies rotate in opposite directions. At the same time, because part of the stepped surfaces overlap each other, it is surely suitable for objects to be crushed with different sizes such as gas lighters made of vinyl, etc. and glass balls contained in gas cans, etc. A crushing process can be performed.

Further, a pipe line 16 connected to the vacuum pump 3 through a valve 17 is connected to the first tank 4.

  A second tank 5 is provided on the downstream side of the vacuum pump 3 via a pipe line 18 and a valve 19. The second tank 5 is filled with water 5a as a solvent. And this water 5a has the one end of the pipe line 18 mentioned above inserted. The second tank 5 is connected to a duct 20 leading to the fan 6 or the combustion device 7. A valve 21 is provided in the path between the pipe line 20 and the fan 6, and a valve 22 is connected between the pipe line 20 and the combustion device 7.

  Here, when the vacuum pump 3 is operated, the gas in the container 2 passes through the pipe 14 and the oil 4 a in the first tank 4. The gas that has passed through the oil 4 a passes through the pipe line 16 and is sucked into the vacuum pump 3, and the gas is discharged to the downstream side of the vacuum pump 3.

  Next, the gas discharged from the vacuum pump 3 passes through the pipe 18 and the water 5 a in the second tank 5. By allowing the water 5a to pass through, the odor contained in the gas can be removed. The gas from which the odor has been removed passes through the pipe line 20 and is supplied to the fan 6 for diluting the gas concentration or the combustion device 7 for burning the gas. Here, the vacuum pump 3, the first and second tanks 4, 5, the fan 6, and the combustion device 7 constitute a specific example of the discharge device according to the crushed object processing device of the present invention.

  In addition to the above configuration, the crushed object processing apparatus 1 includes a control device using a sequencer (not shown), and the entire processing device is controlled by this control device.

Further, the detection result of the pressure gauge 13 is transmitted as an electric signal to a control device (not shown). Then, the control device automatically performs the opening / closing operation of each valve from the operation and stop of the vacuum pump 3 and the fan 6 or the combustion device 7 by a program installed in advance in the sequencer.

  Next, the details in the container 2 of the object to be crushed 1 will be described with reference to FIGS. 2 is a diagram showing the positional relationship between the crusher 9 provided inside the container 2 and an electric motor 32 for driving the crusher 9, FIG. 3 is a cross-sectional view taken along the line AA 'in FIG. 2, and FIG. It is a figure which carries out the cross section and shows the input part 34 and the crusher 9 which concern on a processing apparatus.

  As shown in FIG. 2, the crusher 9 is disposed inside the container 2, whereas the electric motor 32 that is a drive unit that drives the crusher 9 is connected to the container 2 via the speed reducer 33. It is installed outside. That is, the electric motor 32 is connected to the rotating shaft of the crusher 9 via the speed reducer 33 so that the rotation of the electric motor 32 is converted to a low speed by the speed reducer 33 and rotates the rotating shaft of the crusher 9. It has become. Here, although the shaft through hole which penetrates the axis | shaft of the electric motor 32 is provided in the side surface of the container 2, it has the structure where the gas in the container 2 does not leak outside. A bracket (not shown) that supports the electric motor 32 is fixed to the side wall of the container 2.

  Thus, by installing the electric motor 32 outside the container 2, the electric motor 32 can be isolated from the combustible gas remaining in the gas can or the like charged in the container 2. Thereby, even if the combustible gas explodes in the container 2, the electric motor 32 can be protected from the explosion.

  As described above, the hatch 10 is disposed below the crusher 9, and a hermetic door 36 is provided in front of the side surface of the hatch 10. An elevating mechanism 37 that lifts one side of the hatch 10 is provided at the bottom of the hatch 10. When the elevating mechanism 37 is activated, the hatch 10 is tilted to the dotted line position shown in FIG. Accordingly, the hatch 10 can be easily taken out by operating the lifting mechanism 37 and tilting the hatch 10 toward the sealed door 36.

  As shown in FIGS. 3 and 4, in the upper part of the crusher 9, a funnel-shaped charging unit 34 into which a material to be crushed is charged, and a storage unit 35 in which the material to be crushed in the charging unit 34 is stored. Is provided. A paddle pusher 31 that pushes the object to be crushed into the storage unit 35 is provided inside the input unit 34.

  The paddle pusher 31 includes a rotating shaft 31a, two pressing pieces 31b attached to the rotating shaft 31a, and a connecting gear 31c provided at one end in the axial direction of the rotating shaft 31a. The paddle pusher 31 has a function to push the object to be crushed into the storage unit 35 and the crusher 9 by rotating the two pressing pieces 31b and 31b. As shown in FIG. 3, the connecting gear 31 c of the paddle pusher 31 is connected to a rotating shaft 41 of the crusher 9 described later and a belt 38 so as to rotate in conjunction with the rotation of the crusher 9. It has become. In this example, the number of the pressing pieces 31b of the paddle pusher 31 is two, but may be three or more.

  Next, details of the crusher 9 of this example will be described with reference to FIGS. 5 is a cross-sectional view taken along line BB ′ of FIG. 2, FIG. 6 is a perspective view of the crusher 9, FIG. 7 is a side view of the crusher 9, and FIG. 8 is a perspective view of a rotating body constituting the crusher 9. 9 is a schematic diagram showing the overlapping of the crushing blades of the crusher 9.

  As shown in FIG. 5, the crusher 9 includes a first rotating shaft 41, a second rotating shaft 42 disposed substantially in parallel with the first rotating shaft 41 at a predetermined interval, and six Rotating bodies 43A to 43F, two rotating shafts 41 and 42, and a case 44 surrounding the rotating bodies 43A to 43F are provided.

  The case 44 has a hollow, substantially rectangular parallelepiped shape, and an upper surface and a lower surface are opened. Two opening holes (not shown) through which the two rotation shafts 41 and 42 are inserted are opened on the side surface of the case 44. And the bearing 45 which supports the two rotating shafts 41 and 42 rotatably is provided in these two opening holes, respectively. In this example, a rolling bearing is used as the bearing 45, but the present invention is not limited to this. In addition, the lower edge of the case 44 has a plurality of first fixing portions 46 for fixing the case 44 in the container 2 by a fixing method such as screwing (see FIGS. 3 and 4). . Further, the upper edge of the case 44 has a plurality of second fixing portions 47 for fixing the storage portion 35 to the case 44 by a fixing method such as screwing (see FIGS. 3 and 4).

  The first rotating shaft 41 has a cylindrical shape, and has two engaging convex portions 41a and 41a on the side surface of the shaft (see FIG. 7). One end of the first rotating shaft 41 in the axial direction is connected to a speed reducer 33 disposed outside the container 2, and the rotational force from the electric motor 32 is transmitted to the first rotating shaft 41. A first gear 48 is provided at the other axial end of the first rotating shaft 41. Further, the first rotating shaft 41 is connected to the paddle pusher 31 via the belt 38 as shown in FIG.

  The second rotating shaft 42 has a cylindrical shape like the first rotating shaft 41, and has two engaging convex portions 42a and 42a on the side surface of the shaft (see FIG. 7). . The other end of the second rotating shaft 42 in the axial direction has a second gear 49 that is connected to the first gear 48 of the first rotating shaft 41 outside the case 44. The first gear 48 and the second gear 49 are connected to transmit the rotational force of the first rotating shaft 41 to the second rotating shaft 42. As a result, the first rotating shaft 41 and the second rotating shaft 42 rotate in opposite directions, that is, in the directions of the arrows shown in FIG.

  As shown in FIGS. 5 and 6, the first rotating shaft 41 is attached with three rotating bodies 43 </ b> A, 43 </ b> B, and 43 </ b> C that are first rotating bodies. Similarly, three rotating bodies 43D, 43E, and 43F, which are second rotating bodies, are attached to the second rotating shaft 42. As shown in FIGS. 7 and 8, the rotating body 43 has a substantially disc shape, and includes a shaft portion 50, a bearing hole 51 through which the rotating shafts 41 and 42 are inserted, a plurality of crushing blades 52, and a step portion. 53 and so on. The shaft portion 50 has a disk shape, and a bearing hole 51 is provided at the approximate center thereof. In the bearing hole 51, two engaging recesses 51a and 51a that are engaged with the engaging protrusions 41a and 42a of the rotary shafts 41 and 42 are formed. A plurality (10 in this example) of crushing blades 52 are provided on the side surface of the rotating body 43.

  The crushing blade 52 has a claw shape, and continuously protrudes from approximately half of the side surface of the rotating body 43 toward the outside in the radial direction. The crushing blade 52 has a step at a position that is substantially bisected in the width direction, and a first crushing blade 52a is formed on one side in the width direction and a second crushing blade 52b is formed on the other side in the width direction ( (See FIG. 8). The first crushing blade 52a and the second crushing blade 52b have different projecting heights from the side surface of the shaft portion 50. In this example, the 2nd crushing blade 52b located in the inner side (other side) of the width direction is set to the substantially half height of the 1st crushing blade 52a.

  Moreover, as shown in FIG. 9, the thickness in the width direction of the crushing blade 51 is set to M, and the thickness in the width direction corresponding to one of the first and second crushing blades 52a and 52b is M. Is set to approximately half of N (N = M / 2). In addition, it is preferable that the thickness M of the crushing blade 52 is larger than, for example, a glass bulb included in a gas can that is an object to be crushed, and a thickness N corresponding to one of the first and second crushing blades 52a and 52b. Is preferably smaller than a relatively small object to be crushed, such as a gas lighter.

  Further, a stepped portion 53 is provided on the remaining half of the side surface of the rotating body 43, that is, on the other side in the width direction of the rotating body 43. The step portion 53 includes a first step portion 53a and a second step portion 53b that continues from the first step portion 53a with a predetermined step. In this example, the step height of the stepped portion 53 is set to be substantially equal to the difference in height between the first crushing blade 52a and the second crushing blade 52b of the crushing blade 52. The thickness in the width direction of the first stepped portion 53a and the second stepped portion 53b is equal to the thickness N of one of the first and second crushing blades 52a and 52b (see FIG. 8) of the crushing blade 52. It is set to be. Thus, the crushing blade 52 having a step and the step portion 53 make the rotating body 43 smaller in radius in four stages from one end side to the other end side in the axial direction.

  5 and 6, the rotating bodies 43A to 43C attached to the first rotating shaft 41 and the rotating bodies 43D to F attached to the second rotating shaft 42 include the rotating shaft 41, The direction of attaching to 42 is opposite. That is, the direction of the crushing blade 52 of the rotating bodies 43A to 43C attached to the first rotating shaft 41 is opposite to the direction of the crushing blade 52 of the rotating bodies 43D to 43F attached to the second rotating shaft 42. . Therefore, the crushing blade 52 of the rotating bodies 43A to 43C faces the stepped portion 53 of the rotating bodies 43D to 43F, and the crushing blade 52 of the rotating bodies 43D to 43F faces the stepped portion 53 of the rotating bodies 43A to 43C. doing. And as shown in FIG. 9, the level | step difference surface 54 of the crushing blade 52 and the part of level | step difference surface 55 formed of the 1st level | step-difference part 53a and the 2nd level | step-difference part 53b of the rotating body 43 which opposes mutually overlap. It has become. A portion where the stepped surface 54 of the crushing blade 52 and the stepped surface 55 of the stepped portion 53 overlap acts like a scissors blade and crushes the object to be crushed.

  Here, as described above, the thickness of the first and second crushing blades 52a and 52b of the crushing blade 52 is set smaller than a relatively small object to be crushed such as a gas lighter. As a result, the object to be crushed is surely sandwiched between portions where the step surface 54 of the crushing blade 52 and the step surface 55 of the step portion 53 overlap. Thereby, even a gas lighter formed of vinyl can be reliably crushed without stretching. Furthermore, the thickness in the width direction of the crushing blade 51 is set to be larger than the glass sphere included in the gas can or the like. Therefore, since the glass sphere enters between the crushing blade 51 and the stepped portion 52 of the rotating body 43 that faces the glass sphere, the glass sphere can be reliably crushed. Thus, according to the crusher of this example, it is possible to reliably process objects to be crushed having different sizes and materials, such as a gas lighter formed of vinyl or a glass bulb of a gas can.

  In this example, the number of rotating bodies 43 attached to the first and second rotating shafts 41 and 42 is set to three, but the present invention is not limited to this. For example, the first and second rotating shafts Two or four or more rotating bodies 43 may be attached to 41 and 42, respectively. Furthermore, although the number of the crushing blades 52 of the rotating body 43 is 10 in this example, it may be 9 or less, or 11 or more.

  Next, the crushing process of the to-be-crushed object processing apparatus 1 provided with the crusher 9 which has such a structure is demonstrated. As an initial state, all the valves 12, 15, 17, 19, 21, 22, and 24 shown in FIG. 1 are closed. Next, as shown in FIG. 2, the lid 2 a is opened, and an object to be crushed such as a gas can or a lighter discarded in the container 2 is put into the feeding unit 34. Then, the object to be crushed is pressed by the pressing piece 31 b of the paddle pusher 31 provided above the crusher 9, and sent into the storage unit 35. In this state, the lid 2a of the container 2 is closed, and the sealing door 36 of the hatch 10 disposed at the lower part of the crusher 9 is also closed. Therefore, the container 2 is blocked from the outside.

  Next, the valves 15, 17, 19 and 21 shown in FIG. 1 are opened, and the vacuum pump 3 and the fan 6 are operated. Then, the air in the container 2 flows in the direction of the arrow, and the inside of the container 2 is depressurized by the vacuum pump 3 and the fan 6 by the suction force. Then, the air in the container 2 passes through the vacuum pump 3 and is forcibly exhausted from the fan 6 to the atmosphere. At this time, since the suction force of the fan 6 is set to be sufficiently larger than the protruding amount of the vacuum pump 3, the gas or the like in the container 2 can be diluted.

  The degree of this reduced pressure is a pressure that can maintain an oxygen concentration that does not cause an explosion even if combustible gas is ejected from the object to be crushed, and is specifically about 400 to 500 mmHg. This reduced pressure state is detected by the pressure gauge 13 one by one. When the inside of the container 2 is depressurized to a predetermined pressure, the vacuum pump 3 and the fan 6 are stopped. Then, the valves 15, 17, 19 and 21 are closed, and the valve 24 is opened to fill the container 2 with the nitrogen gas 8 from the nitrogen gas supply source 8. Then, when the pressure in the container 2 is increased to atmospheric pressure, the oxygen concentration in the container 2 decreases to less than 13%, which is the explosion limit.

  When the oxygen concentration in the container 2 becomes less than the explosion limit, the valve 24 is closed, the valves 15, 17, 19 and 21 are opened again, and the vacuum pump 3 and the fan 6 are operated. Thereby, the atmospheric | air pressure in the container 2 falls again.

  When it is confirmed that the inside of the container 2 has been depressurized to a predetermined pressure, the electric motor 32 shown in FIG. 2 is turned on to start the operation of the crusher 9. When the operation of the crusher 9 is started, the two rotating shafts 41 and 42 are rotated, and the crushing blade 52 provided on the rotating body 43 and the stepped portion 53 provided on the opposing rotating body 43 cause the object to be crushed. It is crushed. The object to be crushed is dropped below the crusher 9 and collected in the case 10.

  At this time, the gas remaining from the object to be crushed may be ejected or the liquid material may flow out. In that case, although it mixes with a solvent in the container 2, a part becomes mist shape and floats in the container 2. FIG. The floating mist passes through the oil line 4 a filled in the first tank 4 through the pipe line 14 together with the gas in the container 2. Thus, by passing through the oil 4a, it can be supplemented by being melted in the oil 4a, confined by the viscosity of the oil 4a, or liquefied and dissolved in the oil 4a.

  In this way, various liquid substances that flow out when the object to be crushed such as a gas can is crushed and remain in the container 2 can be almost supplemented by the oil 4a. As a result, the only addition to the vacuum pump 3 is propane gas, butane gas, etc. that cannot be supplemented by the oil 4a. As a result, it is possible to greatly reduce the load applied to the vacuum pump 3. Furthermore, since the gas diluted by the gas concentration dilution fan 6 or the gas burned by the combustion device 7 is only propane gas, butane gas or the like, no toxic gas is generated even if it is burned. In addition, sparks may be generated when the object to be crushed is crushed by the crusher 9, but the container 2 is in a state of being filled with a low oxygen state and an incombustible gas, and thus may explode. There is no.

  Further, when the pressure in the container 2 rises from a predetermined value due to gas injection from the object to be crushed, the operation of the crusher 9 is stopped, and the inside of the container 2 is depressurized to a predetermined pressure by the vacuum pump 3 and the fan 6. It is preferable to wait until it is done. And the crushing process is performed by repeating the process as described above.

  And when all the to-be-crushed materials are crushed and there are no unprocessed materials to be crushed in the container 2, generation of new gas due to the crushed materials is stopped. Then, the pressure of the pressure gauge 13 starts to decrease. Therefore, an appropriate pressure is set in advance, and when the pressure falls to the set value, the operation of the crushed object processing apparatus 1 is stopped because the crushing process is completed. Then, when the pressure in the container 2 becomes substantially equal to the atmospheric pressure, the hatch 10 is opened and the crushed object is taken out. Further, the drain valve 12 is opened, and the liquid material of the material to be crushed in the container 2 is discharged to the conduit 11. Thus, the crushing process of the to-be-crushed object by the to-be-crushed object processing apparatus 1 of this invention is complete | finished.

  Next, a second embodiment of the rotating body will be described with reference to FIGS. 10A is a perspective view showing the first embodiment of the crushing blade, FIG. 10B is a perspective view showing the second embodiment of the crushing blade, and FIG. 11 shows the overlapping of the crushing blades according to the second embodiment. It is a schematic diagram shown.

  As shown in FIG. 10A, in this example, the angle of the blades in the first and second crushing blades 52a and 52b is set to approximately 90 degrees with respect to the step surface 54, but the present invention is not limited to this. As in the crushing blade 62 according to the second embodiment shown in FIG. 10B, the corners of the first and second crushing blades 62 a and 62 b may be set at an obtuse angle with respect to the step surface 64. Accordingly, as shown in FIG. 11, the stepped portion 63 (the first stepped portion 63 a and the second stepped portion 63 b) is also preferably formed to have an obtuse angle with the stepped surface 65. Thus, by making the angle of the crushing blade 62 an obtuse angle and forming the blade obliquely with respect to the side surface of the rotating body 43, the object to be crushed can be easily caught in the crushing blade 62, and the crushing process can be performed more reliably. Can do.

Next, a third embodiment of the rotating body will be described with reference to FIGS. FIG. 12 is a perspective view showing a rotating body, and FIG. 13 is a schematic view showing overlapping of crushing blades.
As shown in FIGS. 12 and 13, in the rotating body 73 according to this embodiment, the crushing blade 82 is provided with two steps. That is, the crushing blade 82 according to this example is formed with a first crushing blade 82a, a second crushing blade 82b, and a third crushing blade 82c from one side in the width direction. Further, the stepped portion 83 according to the present example includes a first stepped portion 83a, a second stepped portion 83b that continues from the first stepped portion with a predetermined step so that the number of steps of the crushing blade 82 is equal, and further, The third step portion 83c is continuous from the two step portions 83b with a predetermined step.

  As shown in FIG. 13, a part of the first step surface 84a formed by the first crushing blade 82a and the second crushing blade 82b is partly formed by the second step portion 83b and the third step surface 83c. The second step surface 84b that overlaps the two step surfaces 85b and is formed by the second crushing blade 82b and the third crushing blade 82c is the first step surface 85a that is formed by the first step portion 83a and the second step portion 83b.
