FIG. 1 is a side view showing the overall configuration of the cleaning system 100. FIG. 2 is a front view showing the overall configuration of the cleaning system 100. Note that FIG. 2 is a view seen from the direction of arrow A shown in FIG. The cleaning system 100 of the present embodiment includes a dry cleaning device 10, a transport device 50, a heating device 60, a vertical transport device 70, and a dust collecting device 80. Here, an outline of each device will be described.

First, a dry cleaning device (hereinafter referred to as a cleaning device) 10 has a role of cleaning waste plastic by mixing and stirring waste plastic input from an inlet and a heated cleaning material. Further, when moisture is attached to the waste plastic, it has a role of washing and removing moisture and drying.
Further, the cleaning device 10 separates the waste plastic and the cleaning material, discharges the waste plastic from the outlet, and drops the cleaning material and dust, dust, dirt, and the like from the opening.
The transport device 50 transports the cleaning material and dust, dust, dirt, and the like dropped from the opening of the cleaning device 10 to the heating device 60.

The heating device 60 heats the cleaning material conveyed by the conveyance device 50 to a predetermined temperature and conveys it to the vertical conveyance device 70.
The vertical conveyance device 70 conveys the heated cleaning material to the charging port of the cleaning device 10 and puts the cleaning material into the charging port.
Further, the dust collector 80 sorts out the cleaning material and the dust, dirt, dirt, etc. other than the cleaning material from the cleaning material dropped from the opening of the cleaning device 10.
The cleaning system 100 is processed by the apparatus as described above to dry the waste plastic and clean the waste plastic. In addition, the cleaning material used when cleaning the waste plastic is heated and used again.

Next, the configuration of each device will be described in detail. First, the structure of the washing | cleaning apparatus 10 is demonstrated with reference to FIGS. For convenience of explanation, in each figure, the front of the cleaning apparatus 10 is indicated as Fr, and the rear is indicated as Rr.
First, as shown in FIGS. 1 and 2, the cleaning device 10 has a main body cover 13 that is disposed in a state of being separated from the floor surface by a base 11. As shown in FIG. 2, the main body cover 13 is formed in a substantially rectangular cross section with a hollow inside, and is disposed with the longitudinal direction set in the horizontal direction. The main body cover 13 is configured to surround the entire case body 20 as a screen formed in a substantially cylindrical shape.

Here, in front of the main body cover 13, an input portion 14 for supplying waste plastic and heated sand as a cleaning material into the case body 20 is integrally provided. Further, an outlet 15 for discharging the waste plastic is integrally provided behind the main body cover 13.
Here, referring to FIG. 3 showing a cross-sectional view of the cleaning device 10, the insertion port 14 a of the insertion unit 14 opens upward and obliquely forward. Further, the throwing portion 14 is formed with an inclined portion 14b for guiding the waste plastic into the main body cover 13 when throwing the waste plastic.
On the other hand, the blower outlet 15a of the blowout part 15 is open downward and obliquely rearward. Further, the blowout portion 15 is formed with an inclined portion 15b for guiding the waste plastic sent backward from the inside of the main body cover 13 to the blowout port 15a.

Furthermore, a plurality (four) of exhaust ducts 16 for exhausting the air in the main body cover 13 are provided above the main body cover 13 so as to open upward. A filter 17 is disposed in the exhaust duct 16. When exhausting air from the inside of the main body cover 13, the filter 17 exhausts the dirt component contained in the air after filtering it.
In the present embodiment, as shown in FIG. 3, an induction fan 18 is provided in each exhaust duct 16. The induction fan 18 forcibly attracts and exhausts the air in the main body cover 13. By forcibly exhausting in this way, the flow of waste plastic in the case body 20 is rectified (exhausting increases the action in the direction of centrifugal force and enhances the cleaning effect by the rubbing effect) as will be described later. Can do. Furthermore, the attracting fan 18 of the present embodiment is configured so that the displacement can be adjusted by adjusting the rotational speed, for example.

  Also, below the main body cover 13, a dropping part 19 where the heated sand falls is provided integrally. An opening 19 a that opens downward is formed in the drop part 19 over the longitudinal direction of the drop part 19.

Next, the case body 20 will be described with reference to FIGS.
As described above, the case body 20 is formed in a substantially cylindrical shape, and the inside of the cylindrical shape is formed with a stirring space 21 for mixing and stirring the waste plastic charged from the charging port 14a and the heated sand. . The stirring space 21 of the present embodiment is configured such that the first stirring space 21a in the first half and the stirring space 21b in the second half are adjacent in a substantially horizontal state. More specifically, the first agitation space 21 a and the second agitation space 21 b are configured to partition both spaces by a partition member 23.

The partition member 23 partitions only the upper side of the boundary between the first stirring space 21a and the second stirring space 21b. Specifically, referring to FIG. 4 showing a perspective view of the inside of the case body 20, the partition member 23 is formed in a substantially semicircular shape, and is disposed so as to partition the substantially upper half of the stirring space 21. Therefore, the waste plastic and the heated sand mixed in the first stirring space 21a pass through only the lower part of the partition member 23 and are sent out to the second stirring space 21b. By disposing the partition member 23 in this way, it is possible to prevent a large amount of waste plastic from being sent to the second stirring space 21b, and to secure a residence time in the first stirring space 21a. Furthermore, the partition member 23 can cause the air heated by the heated sand to be swept into the first stirring space 21a.
As shown in FIGS. 3 and 4, the partition member 23 is arranged so that the upper side is inclined forward. Therefore, due to this inclination, the mixed waste plastic and the heated sand are moderately urged and guided to the second stirring space 21b.

In addition, a plurality of discharge holes 22 through which heated sand, dust, dirt, and the like are discharged are provided on the peripheral surface of the case body 20. The diameter of the discharge hole 22 is formed such that heated sand, dust, dirt, etc. are discharged, but waste plastic is not discharged.
The positions of the discharge holes 22 are different between the case body 20a that forms the first stirring space 21a and the case body 20b that forms the second stirring space 21b. Specifically, the discharge holes 22 are provided more on the peripheral surface of the case body 20b than on the peripheral surface of the case body 20a. In other words, the total opening area of the discharge holes 22 is formed so that the peripheral surface of the case body 20b is wider than the peripheral surface of the case body 20a.
In this embodiment, as shown in FIG.3 and FIG.4, in the case body 20a, the discharge hole 22 is provided in the lower peripheral surface among the peripheral surfaces. Further, in the case body 20b, a discharge hole 22 is provided on the entire peripheral surface. Thus, by changing the positions where the discharge holes 22 are provided in the first stirring space 21a and the second stirring space 21b, the role in the stirring space can be shared as will be described later.

  In addition, as shown in FIGS. 2 and 3, the cleaning device 10 is provided with a rotating shaft 24 that passes through the center of the case body 20. The rotary shaft 24 is rotatably supported via a bearing unit 25 a erected from the base 11 and a bearing unit 25 b disposed on the case body 20. A motor 26 as a drive unit is connected in front of the rotating shaft 24. Therefore, the rotating shaft 24 can be rotated by driving the motor 26. In the present embodiment, the rotary shaft 24 and the output shaft of the motor 26 are connected coaxially, but may be connected indirectly via an idle gear, a belt, or the like.

  In addition, the rotating shaft 24 is provided with a plurality of rotating blades 27 including a plurality of stirring blades 28 as stirring members. The rotary blades 27 are separated from each other at appropriate intervals, and rotate in synchronization with the rotary shaft 24 in the stirring space 21. By rotating the rotary blade 27, the waste plastic mixed in the case body 20 and the heated sand can be stirred. As shown in FIG. 3, three rotating blades 27 of the present embodiment are provided in each of the first stirring space 21a and the second stirring space 21b. Note that the number and interval of the rotary blades 27 are not limited to those described above, and can be changed as appropriate according to the degree of contamination of the waste plastic to be stirred.

  Further, as shown in FIG. 4, the rotating blade 27 of the present embodiment has four stirring blades 28 attached in a cross shape. Further, the stirring blades 28 of the adjacent rotating blades 27 are out of phase with each other. That is, when viewed from the front (when viewed from the direction of arrow B shown in FIG. 4), the adjacent agitating blades 27 are configured such that the agitating blades 28 located at the rear do not overlap the agitating blades 28 located at the front. Has been. In the present embodiment, the front and rear stirring blades 28 are arranged with a phase shift of approximately 45 degrees. As described above, the turbulent flow is generated in the stirring space 21 by shifting the phase of the stirring blade 28, and the waste plastic and the heated sand can be further stirred.

Next, paying attention to the stirring blades 28, each stirring blade 28 is formed in a plate shape as shown in FIG. 4 and has a length to reach the inner peripheral surface of the case body 20.
Further, the stirring blade 28 of the rotating blade 27 is configured to be adjustable in angle with respect to the axial direction of the rotating shaft 24. Here, the angle adjusting mechanism of the stirring blade 28 will be described with reference to FIG. FIG. 5 is an exploded perspective view in which the rotary blade 27 is disassembled.
As shown in FIG. 5, the rotary blade 27 has a turntable 29 fixed to the rotary shaft 24. An attachment hole 30 as an attachment portion for attaching the stirring blade 28 is formed on the outer periphery of the turntable 29. On the other hand, a circular protrusion 31 is formed on the base end side of the stirring blade 28 as an attachment portion that is fitted into the attachment hole 30. Here, the circular protrusion 31 of the stirring blade 28 is fitted into the mounting hole 30 of the turntable 29 in a state where the stirring blade 28 is rotated to a desired angle in the direction of arrow C shown in FIG. Next, the fixing bolt 34 is screwed through the screw hole 32 formed in the turntable 29. Then, the tip of the fixing bolt 34 comes into contact with the circular protrusion 31 of the stirring blade 28, and the stirring blade 28 is fixed to the turntable 29 in a state adjusted to a desired angle.

Thus, the angle of each stirring blade 28 can be freely adjusted with respect to the rotary table 29. Here, as shown in FIG. 4, an angle θ (for example, 45 degrees) between the angle (0 degrees) at which the stirring blade 28 is parallel to the axial direction of the rotary shaft 24 and the angle (90 degrees) perpendicular to the axis direction. Attach it at an angle. Then, when the rotary blade 27 rotates, an air flow in the axial direction of the rotation shaft 24 and in the rear direction can be generated along with the air flow in the circumferential direction of the case body 20.
At this time, by adjusting the angle of the stirring blades 28 by the angle adjusting mechanism described above, the air flow toward the rear can be adjusted, so that the waste plastic stirred in the stirring space 21 and the heated sand are blown out. The speed and the like sent out to the part 15 side can be controlled.

  Further, as shown in FIG. 5, a protective cover 33 that covers the base ends of the rotary table 29 and the stirring blade 28 is detachably attached to the rotary blade 27. The protective cover 33 protects the waste plastic from being entangled with the base ends of the turntable 29 and the stirring blade 28. The protective cover 33 is attached to each rotary blade 27.

Next, the cleaning process performed by the cleaning apparatus 10 configured as described above will be described.
First, the motor 26 is driven to rotate the rotary blade 27 in the first stirring space 21a and the second stirring space 21b. The induction fan 18 provided in the exhaust duct 16 is also driven in the same manner.
Next, waste plastic and heated sand are charged from the charging port 14a. Here, it is assumed that the waste plastic is attached with moisture due to factors such as being left outdoors. The sand to be added is heated at a temperature lower than the temperature at which the plastic melts. Here, it is assumed that the waste plastic in the form of a film that has been sorted in advance and cut to an appropriate size is used as the waste plastic. Moreover, in order to make it easy to mix waste plastic and the heated sand in the stirring space 21, it is preferable to add simultaneously.

Next, the waste plastic and heated sand introduced from the inlet 14a enter the first stirring space 21a. In the first stirring space 21a, the waste plastic and the heated sand are stirred in a mixed state by the rotation of the plurality of rotary blades 27. At this time, mainly in the first stirring space 21a, the waste plastic and the heated sand are mixed and rubbed together, so that the heated sand absorbs moisture adhering to the waste plastic. Since sand has a large surface area, sand easily mixes with waste plastic, and can instantly absorb moisture adhering to the waste plastic.
Furthermore, the inside of the first stirring space 21a is heated by heated sand. Moreover, since the partition member 23 partitions the upper part of the boundary with the second stirring space 21b, the heat in the upper part in the first stirring space 21a is particularly high. Therefore, the waste plastic to which moisture has adhered is dried rapidly while being stirred.

  In the first stirring space 21a, as described above, the discharge hole 22 is formed only on the lower peripheral surface. Therefore, even when the airflow from the center of the case body 20a toward the outer circumferential direction is generated by the rotary blade 27, most of the sand scattered in the circumferential direction by the airflow is the case body 20a in which the discharge hole 22 is not formed. It just collides with the inner peripheral surface, and is not discharged from the first stirring space 21a. Therefore, in the first stirring space 21a, the heated sand can be engaged in the role of drying the waste plastic.

  On the other hand, among the heated sand, the sand that has absorbed the moisture of the waste plastic is gradually moved under the case body 20a by its own weight because the temperature decreases and the weight increases due to the moisture. As a result, it falls downward from the discharge hole 22 formed in the lower part of the case body 20a. After that, it drops from the cleaning device 10 to the transport device 50 through the opening 19 a of the dropping portion 19 formed in the main body cover 13. Since the discharge hole 22 has a diameter smaller than the size of the waste plastic, the waste plastic is not discharged and only the sand is discharged.

  In the first agitation space 21a, as described above, an airflow is generated in the axial direction of the rotating shaft 24 and toward the blowing portion 15 due to the inclination of the agitation blade 28. Therefore, the waste plastic and the heated sand are sent out toward the rear of the first stirring space 21a while rotating. At this time, since the stirring blades 28 of the rotary blades 27 adjacent to each other are out of phase, the waste plastic and the heated sand can easily collide with the rear stirring blades 28 and can be further stirred. ing. This effect is the same in the second stirring space 21b.

  Further, the partition member 23 prevents a large amount of waste plastic and heated sand from being sent out to the second agitating space 21b due to a backward airflow, and ensures a residence time in the first agitating space 21a. To do. Further, due to the inclination of the partition member 23, the waste plastic and the heated sand are appropriately promoted to move to the second stirring space 21b and guided to the second stirring space 21b.

In addition, since the attracting fan 18 forcibly attracts the air in the main body cover 13 and thus the first stirring space 21a, the feeding speed of the waste plastic and sand due to the airflow to the rear is reduced, and the first fan 18 The flow of waste plastic and sand in the stirring space 21a is rectified. This effect is the same in the second stirring space 21b.
Thus, mainly in the first stirring space 21a, the waste plastic can be dried by mixing the waste plastic containing moisture and the heated sand. At this time, the role of drying is finished, and the water-containing sand is discharged from the first stirring space 21a at an early stage, so that the efficiency of drying the waste plastic is increased.

  Next, the waste plastic sent from the lower part of the partition member 23 and the heated sand enter the second stirring space 21b. Similarly, in the second stirring space 21b, the waste plastic and the heated sand are stirred in a mixed state by the rotation of the plurality of rotary blades 27. At this time, mainly in the second agitation space 21b, the waste plastic and the heated sand are mixed and rubbed together, so that the heated sand cleans dust, dirt, dirt, etc. attached to the waste plastic. To do. Further, in the second stirring space 21b, the mixed waste plastic and the heated sand are separated.

Specifically, in the second agitation space 21b, the heated sand rubs against the waste plastic, thereby scraping off dust, dirt, dirt, and the like attached to the waste plastic. Further, the stirring blade 28 of the rotary blade 27 causes an action in the direction of centrifugal force, causing the waste plastic to collide and rub against the case body. Due to this impact or the like, dust, dirt or dirt attached to the waste plastic is generated. It is knocked down. Furthermore, since the waste plastic changes into various shapes due to unpredictable turbulence generated by the rotary blade 27, dust, dirt, dirt, and the like attached to the waste plastic are removed by the impact at the time of the change.
At this time, since the stirring blade 28 is made of a flexible material (for example, urethane rubber), even if an excessive amount of waste plastic is thrown in more than a predetermined amount, the stirring blade 28 can flexibly respond to the stirring blade. It is possible to prevent the 28 from being damaged. Further, when the impeller 28 collides with the waste plastic, it can be prevented from being crushed more than necessary.
Note that the cleaning with the waste plastic as described above is gradually performed in the first stirring space 21a as the waste plastic is dried.

Further, in the second stirring space 21b, as described above, the discharge holes 22 are formed on the entire circumferential surface. Therefore, since the airflow toward the circumferential direction of the case body 20b is generated by the rotary blades 27, the sand scattered in the circumferential direction by the airflow simultaneously with the cleaning described above passes through the discharge hole 22 in the second stirring space 21b. It will be discharged from. At this time, dust, dust, dirt, and the like scraped off by the cleaning are discharged from the second stirring space 21b through the discharge hole 22 in the same manner as the sand. Similarly, some waste plastics are scattered in the circumferential direction. However, since the discharge hole 22 has a diameter smaller than the size of the waste plastics, only sand is discharged.
The heated sand and dust discharged from the second stirring space 21 b pass through the gap between the case body 20 b and the main body cover 13 and pass through the opening 19 a of the dropping portion 19 formed in the main body cover 13. Then, it drops from the cleaning device 10 to the transport device 50.
On the other hand, the washed waste plastic is sent to the blowing portion 15 by an air flow directed backward by the rotary blade 27, whereby the heated sand and the waste plastic can be separated and taken out separately.

Thus, mainly in the second stirring space 21b, the waste plastic can be washed with high detergency by mixing and stirring the waste plastic and the heated sand. Moreover, waste plastic and heated sand can be separated and taken out separately.
As described above, according to the cleaning device 10 according to the present embodiment, when cleaning waste plastic, there is no need to clean with a cleaning liquid or the like, so there is no need for a cleaning and drying process with a cleaning liquid, and cleaning is performed instantly. It can be performed. Accordingly, the cleaning efficiency can be improved and the processing cost can be reduced. In addition, since the cleaning and drying steps with the cleaning liquid are not required, the cleaning device itself does not increase in size. Furthermore, even when the waste plastic contains moisture, the processing efficiency can be improved by performing drying or washing of the waste plastic simultaneously or continuously. Thus, according to the cleaning apparatus 10 according to the present embodiment, it is possible to achieve absolutely low cost, space saving, and processing time.

  Moreover, according to the cleaning apparatus 10 according to the present embodiment, the waste plastic is mainly dried in the first stirring space 21a, and the waste plastic is mainly cleaned in the second stirring space 21b. Yes. As described above, since the step of drying the waste plastic is set in the cleaning device 10, the cleaning can be performed efficiently. That is, if cleaning is performed with moisture attached, dirt may simply expand.

Note that the present invention is not limited to the above, and depending on how moisture adheres to the waste plastic, drying in the first stirring space 21a may not be in time, and the waste plastic may dry in the second stirring space 21b. Thus, the cleaning device 10 can also be used as a drying device.
On the contrary, when the waste plastic is dried early in the first stirring space 21a, the cleaning may already be performed in the first stirring space 21a. In this case, the case where moisture does not adhere to the waste plastic also applies.
If it is desired to adjust the delivery speed of the waste plastic due to moisture adhesion or the like, for example, the angle of inclination of the stirring blade 28, the rotational speed of the motor 26, or the stirring space by the induction fan 18 can be adjusted. What is necessary is just to adjust the quantity which attracts the air in 21.

In the above description, the case body 20 of the cleaning device 10 has been described with respect to a case where the cross section is substantially circular. However, the case body 20 is not limited to this case, and the case body 20 may be a cylinder having a cross section of a polygon such as a regular octagon. Good.
In the above description, the stirring blade 28 of the rotating blade 27 is described as being formed of a flexible material such as urethane rubber. However, the present invention is not limited to this case, and the stirring blade 28 is made of iron or hard plastic. A stirring blade 28 may be used. That is, the synergistic effect of the sand washing effect, the rubbing effect generated by the centrifugal force due to the angle of the stirring blade 28 and the feeding force in the discharge direction, and the discharge speed adjusting effect due to the action of the attracting fan 18, results in The material is not asked.

Next, a configuration and processing operation in which the sand used for drying and cleaning is collected in the cleaning system 100, heated again, and reused will be described.
As described above, sand, dust, dirt, dirt, and the like that have dropped from the opening 19 of the cleaning device 10 fall on the transport device 50. Here, the conveyor (conveyor) 50 uses a belt conveyor 50.
The belt conveyor 50 is arrange | positioned directly under the dropping part 19 of the washing | cleaning apparatus 10, as shown in FIG.1 and FIG.2. The belt conveyor 50 collects sand, dust, dust, dirt, and the like and conveys them to a predetermined position. The belt conveyor 50 of this embodiment is conveyed to the heating device 60 and dropped onto the heating surface of the heating device 60.

  Further, as shown in FIG. 1, a dust collector (dust collector) 80 is provided at the end of the belt conveyor 50. The dust collector 80 removes the sand to be reused by the cleaning device 10 from the falling objects falling from the end of the belt conveyor 50 and sucks it from the nozzles. That is, in the dust collector 80, by setting a suction force so that a lighter weight than the weight of sand that can be reused can be sucked, only unnecessary items such as dust, dust and dirt that are lighter than the sand are collected. Aspirate. In this way, the dust collector 80 sorts sand to be reused and unnecessary materials.

  Of the sand used for cleaning by the cleaning device 10, sand that has been scraped off and reduced in size has a reduced cleaning effect. Therefore, the dust collector 80 also sucks the sand that has become smaller together with dust, dirt, dirt, and the like at this stage. Dust, dust, dirt, etc. sucked by the dust collector 80 are collected by a bag filter or the like and discarded. It should be noted that by blowing air to the fallen object falling from the end of the belt conveyor 50, it is possible to assist the sorting of the unwanted matter by suction by the dust collector 80.

Next, the heating device (heating unit) 60 heats the sand that has dropped onto the heating surface. The heating device 60 of the present embodiment is provided with a heating plate 61 as shown in FIG. The hot platen 61 is heated by a heat medium filled therein. Further, the heating device 60 transfers the sand to be reused to the vertical transfer device 70 while heating it. Specifically, the hot platen 61 of the heating device 60 moves sand toward the vertical conveying device 70 by itself generating vibration.
Note that the sand that has fallen on the heating surface includes sand that absorbs moisture adhering to the waste plastic as described above. Accordingly, the heating device 60 heats the absorbed moisture while evaporating and drying the sand while transferring the sand. At this time, since the heating device 60 is transferred with vibration, the sand can be scattered over the entire heating surface. Therefore, the heating device 60 can efficiently heat the sand.
The heating device 60 heats at a temperature not lower than the temperature necessary for drying the moisture adhering to the waste plastic and not higher than the temperature at which the waste plastic melts.

  Next, the vertical conveyance device (vertical conveyance unit) 70 conveys the sand heated by the heating device 60 to the inlet 14 a of the cleaning device 10. The vertical conveyance device 70 of the present embodiment is a so-called vertical bucket conveyor 70, and is configured so that a plurality of buckets 71 can circulate so as to surround the charging unit 14 of the cleaning device 10 as shown in FIGS. Has been. The bucket 71 located below the vertical bucket conveyor 70 passes through a position where it can receive the sand that has been transferred by the heating device 60 and dropped. Further, the bucket 71 positioned above the vertical bucket conveyor 70 passes above the charging unit 14 and, when passing, as shown in FIG. 2, the bucket 71 is reversed and the heated sand is transferred to the charging port 14a. It is configured so that it can be put in. Therefore, the vertical bucket conveyor 70 can automatically perform the process of raising the heated sand and putting it into the charging port 14a of the cleaning device 10.

  As described above, according to the cleaning system 100 according to the present embodiment, the sand used when cleaning is performed by the cleaning device 10 can be collected and heated again to be reused.

First, as shown in FIG. 6, the cleaning device 110 is disposed in a state of being separated from the floor surface by the bases 111a and 111b. Between the bases 111a and 111b, a rotating body 120 as a case body formed in a substantially cylindrical shape is rotatably supported. The rotating body 120 is inclined downward as it goes rearward. This inclination can be adjusted using, for example, an adjuster 112 attached to the legs of the bases 111a and 111b. That is, the cleaning device 110 is provided with an adjustment unit that can adjust the inclination of the rotating body 120. By adjusting the adjuster 112, the discharge speed of the glass thrown into the rotating body 120 can be adjusted.

  The rotating body 120 is integrally configured by connecting a first rotating body 120a, a second rotating body 120b, and a third rotating body 120c. The first rotating body 120a adjacent to the base 111a and the third rotating body 120c adjacent to the base 111b are formed in a hollow metal network structure, that is, a trommel shape. On the other hand, the 2nd rotary body 120b is formed in the hollow cylindrical substantially cylindrical shape. In addition, gears 121a and 121b are arranged on the convex portions formed along the outer periphery of the rotating body 120 at the boundary between the rotating bodies 120a, 120b, and 120c on the outer periphery of the rotating body 120. .

The rotating shaft 115 of the motor 114 is provided with gears 116 a and 116 b that mesh with the gears 121 a and 121 b provided on the rotating body 120. Therefore, the rotating body 120 can be rotated in the direction of arrow D shown in FIG. 6 by driving the motor 114. The driving method for rotating the rotating body 120 is not limited to this case, and any method such as driving with a chain may be used.

Next, the configuration within the rotating body 120 will be described with reference to FIGS.
As shown in FIG. 7 showing a side sectional view of the rotating body 120 and FIG. 8 showing a perspective view of the inside of the rotating body 120, the rotating body 120 has stirring for stirring the glass introduced from the charging unit 113. A space 122 is formed. The stirring space 122 according to the present embodiment includes a first stirring space 122a, a second stirring space 122b, and a third stirring space 122c that are continuously arranged in a horizontal state. Here, the first stirring space 122a, the second stirring space 122b, and the third stirring space 122c are configured by the first rotating body 120a, the second rotating body 120b, and the third rotating body 120c, respectively. .

  In addition, the first stirring space 122a, the second stirring space 122b, and the third stirring space 122c are used to efficiently wind up the glass in each stirring space or to send the glass to the next stirring space, respectively. A plurality of fins 123 as stirring members are provided. Specifically, the fins 123 are attached to the inner peripheral surfaces of the first rotating body 120a, the second rotating body 120b, and the third rotating body 120c. The fins 123 are made of metal and are formed in a rectangular plate shape in a side view. Here, the arrangement position of the fins 123 will be described by taking up the fins 123 disposed in the first stirring space 122a. The second stirring space 122b and the third stirring space 122c are also attached at the same arrangement position.

  Fins 123a, 123b, and 123c are attached to the first stirring space 122a with gaps of a predetermined interval in the discharge direction. First, the plurality of fins 123a attached to the first stage from the entrance of the first stirring space 122a are directed in the direction of the axis F of the rotating body 120a as shown in FIG. 9 viewed from the direction of arrow E in FIG. It is attached to protrude. The plurality of fins 123a are arranged at four positions symmetrical with respect to the axis F. Similarly, four fins 123b attached to the second stage from the entrance of the first stirring space 122a are also arranged at four positions symmetrical with respect to the axis F of the first rotating body 120a. Has been. As shown in FIG. 9, the second-stage fin 123b is attached to the first-stage fin 123a with a fixed angle (for example, 45 degrees) and out of phase with respect to the axis F. That is, when viewed from the front, the fins 123 adjacent to each other in the discharge direction are configured so that the front and rear fins 123 do not overlap.

The third-stage fin 123c is attached so as to have the same phase as the first-stage fin 123a. And each fin 123a, 123b, 123c is attached inclining a little in one direction with respect to the axial direction of the 1st rotary body 120a. That is, as shown in FIG. 9, when the rotating body 120 is viewed from the front, the fins 123 are attached in such a manner that the side surfaces thereof appear.
With the fins 123 arranged in this manner, the glass put into the first stirring space 122a collides with the fins 123 and is wound up by the rotation of the first rotating body 120a. Further, the glass put into the first stirring space 122 a is sent out in the discharge direction by the inclination of the rotating body 120 and the guidance by the inclination of the fins 123. Such movement of the glass is the same in the second stirring space 122b and the third stirring space 122c.
In addition, in the 2nd stirring space 122b, since the distance of a discharge direction is long, more fins 123 are attached than the 1st stirring space 122a and the 3rd stirring space 122c. Note that the number and interval of the fins 123 are not limited to those described above, and may be changed as appropriate.

Further, a screw conveyor 124, a sand injection unit 130, and a compressed air supply pipe 133 are disposed in the rotating body 120.
The screw conveyor 124 functions as a cleaning material transport unit that transports heated sand as the cleaning material to the second stirring space 122b. The screw conveyor 124 is supported by the base 111a, passes through the first stirring space 122a and the second stirring space 122b from the base 111a, and the second stirring space 122b and the third stirring space 122c. It reaches to the boundary part.

A supply port 127 for introducing heated sand is provided in front of the screw conveyor 124, that is, at the entrance of the first rotating body 120a. The heated sand introduced from the supply port 127 is supplied into the pipe 126 of the screw conveyor 124. In addition, an opening hole is provided below the pipe 126 of the screw conveyor 124 located in the second stirring space 122b for dropping the heated sand downward.
According to the screw conveyor 124 configured as described above, the heated sand introduced from the supply port 127 is conveyed to the second agitating space 122b as the screw driving unit (not shown) rotates the screw 125. Then, it falls and is supplied to the sand injection unit 130.

  Next, the sand injection unit 130 functions as a cleaning material injection unit that vigorously injects the heated sand into the second stirring space 122b. A plurality of sand injection sections 130 are provided continuously over the discharge direction of the second stirring space 122b. Specifically, a plurality of screw conveyors 124 are arranged below the pipe 126. The receiving hopper 128 of the sand injection unit 130 receives and stores the sand that has fallen from the pipe 126.

The compressed air supply pipe 133 functions as a compressed air supply unit that supplies compressed air to the nozzle 129 of the sand injection unit 130. The compressed air supply pipe 133 passes through the third stirring space 122c from the base 111b and reaches each sand injection unit 130 disposed in the second stirring space 122b. Then, as shown in a partial cross-sectional view of the sand injection unit 130 in FIG. 10 as viewed from the direction of arrow E in FIG. 7, the compressed air is branched from the compressed air supply pipe 133, and the compressed air reaches the outlets of the nozzles 129. It is like that.
The sand injection unit 130 and the compressed air supply pipe 133 configured in this manner, together with the air supplied from the compressed air supply pipe 133, the sand heated from the nozzle 129 is injected radially and vigorously into the second stirring space 122b. Can be made.

Here, the compressed air supply pipe 133 is arranged along the arrangement duct 131. The arrangement duct 131 is supported by the base 111b, passes through the third stirring space 122c and the second stirring space 122b from the base 111b, and passes through the first stirring space 122a and the second stirring space 122b. To the border. Moreover, the arrangement | positioning duct 131 located in the 2nd stirring space 122b surrounds the sand injection part 130 with the compressed air supply pipe 133. FIG. Therefore, even when the glass is rolled up in the second stirring space 122b, it is possible to protect the glass from colliding with the compressed air supply pipe 133 and the sand injection unit 130 and being damaged.
Note that the screw conveyor 124, the compressed air supply pipe 133 and the sand injection unit 130 provided in the installation duct 131 are indirectly attached to the bases 111a and 111b, so the positions are always fixed. Thus, even if the rotating body 120 rotates, it does not rotate together.

In addition, internal support frames 140 a and 140 b are disposed in the rotating body 120.
The internal support frame 140a is provided at the boundary between the first stirring space 122a and the second stirring space 122b. On the other hand, the internal support frame 140b is provided at the boundary between the second stirring space 122b and the third stirring space 122c.

  As shown in FIGS. 7, 8 and 10, the inner support frames 140 a and 140 b are formed so that the lower semicircular portion of the thick disc is semicircular in the thickness direction of the disc leaving the outer peripheral portions 141 a and 141 b. It is formed in a shape having a space. Further, in the upper semicircular portions of the inner support frames 140a and 140b, there are provided insertion holes into which the pipe 126 and the arrangement duct 131 of the screw conveyor 124 are inserted. Therefore, since the internal support frames 140a and 140b are indirectly attached to the bases 111a and 111b via the pipe 126 and the arrangement duct 131, the positions are always fixed, and the rotating body 120 rotates. But they do not rotate together.

  In front of each of the internal support frames 140a and 140b, a partition member 142a for partitioning the space between the first stirring space 122a and the second stirring space 122b, and the space between the first stirring space 122a and the second stirring space 122b. A partition member 142b for partitioning is provided. The partition members 142a and 142b are formed so that only about 1/3 penetrates downward as shown by the two-dot chain line in FIG. 10 and FIG. Therefore, when the glass is sent from the first stirring space 122a to the second stirring space 122b, or when the glass is sent from the second stirring space 122b to the third stirring space 122c, the partition members 142a and 142b It is sent out only below.

  Further, when the glass is sent out to the next stirring space 122, the inner peripheral surfaces of the outer peripheral portions 141a and 141b, that is, half of the glass so that the glass does not collide with the outer peripheral portions 141a and 141b of the inner support frames 140a and 140b and be damaged. Curved protection plates 143a and 143b are installed on the inner peripheral surface of the circular space.

  A plurality of rollers 150a and 150b are rotatably supported around the inner support frames 140a and 140b, respectively. The rollers 150 a and 150 b are arranged so that the axial center direction is the same as the axial center direction of the rotating body 120. The rollers 150a and 150b are fitted into the space in the convex portion of the rotating body 120, so that the rotating body 120 can be smoothly guided by the rollers 150a and 150b.

Next, the cleaning process performed by the cleaning apparatus 110 configured as described above will be described.
First, the motor 114 is driven and the rotating body 120 is rotated. In addition, heated sand is supplied from the supply port 127 to drive the screw conveyor 124, and the sand injection unit 130 is driven to inject the heated sand.
Next, from the charging unit 113, the glass to which the contaminated mud is attached is charged. Here, it is assumed that moisture is attached to the glass and the attached contaminated mud.

  Next, the glass introduced from the input unit 113 enters the first stirring space 122a. In the 1st stirring space 122a, since the 1st rotary body 120a is rotating, it stirs between glasses. Further, since the fins 123a, 123b, and 123c rotate in the same manner as the first rotating body 120a, the glass is wound up by colliding with the fins 123 and the like. As described above, the rubbing mud, dust, etc. attached to the glass are wiped off by rubbing between the glass, colliding with the fins 123, or generating an impact when the rolled up glass falls. Contaminated mud, dust, etc. that are smaller than the mesh of the first rotating body 120a fall from the first rotating body 120a. Further, the glass is sent out in the discharge direction by the inclination of the rotating body 120 and the guidance by the inclination of the fins 123. Note that the contaminated mud, dust, and the like dropped from the first rotating body 120a are received by the receiving unit 117 shown in FIG. 1 and processed later.

  Further, since the gaps between the fins 123a, 123b, and 123c have predetermined gaps in the discharge direction, for example, the glass positioned between the first-stage fin 123a and the second-stage fin 123b. The roll-up is somewhat stagnant. Therefore, the glass sent out in the discharge direction is continuously rolled up, stagnated, and rolled up, causing the movement of the glass to be sluggish and improving the effect of removing the attached contaminated mud. In addition, since the phases of the adjacent fins 123 are shifted, a change occurs in the roll-up of the glass, and the effect of removing the attached contaminated mud is improved. Thus, in the first stirring space 122a, the contaminated mud adhering to the glass can be removed to some extent.

  Next, the glass fed from below the partition member 142a enters the second stirring space 122b. In the second stirring space 122b, the heated sand is vigorously sprayed radially by the sand sprayer 130 as described above. Therefore, the sand that has been heated has a sandblasting effect due to the impact force that collides with the glass, and the attached contaminated mud is peeled off and washed. In the second stirring space 122b, the fins 123 are rotated by the rotation of the second rotating body 120b, similarly to the first stirring space 122a. Therefore, in the second stirring space 122b, the glass and the heated sand are stirred in a mixed state. At this time, the sand and the heated sand are mixed and rubbed together, whereby the heated sand absorbs moisture adhering to the glass, moisture adhering to the contaminated mud, and the like. In addition, since sand has a large surface area, sand is easily mixed with the glass, and moisture adhering to the glass can be absorbed instantaneously.

  Furthermore, the inside of the second stirring space 122b is heated to high temperature by heated sand. The second stirring space 122b is substantially cylindrical, and the partition members 142a and 142b partition the upper part of the boundary between the first stirring space 122a and the third stirring space 122c, respectively. In particular, heat is generated in the stirring space 122b. Therefore, the glass to which moisture has adhered is dried rapidly while being stirred. By making the glass dry, the sand blasting effect by the heated sand further works, and it becomes easy to peel off the attached contaminated mud.

  In addition, in the second agitation space 122b, the movement of the glass is caused by the fins 123 and the movement of the glass is changed due to the fins 123 as in the case of the first agitation space 122a. The effect of paying off is improved. In addition, the sand injection part 130 is arrange | positioned above the 2nd stirring space 122b. Therefore, since the glass having a large specific gravity does not wind up upward, the glass does not collide with the sand injection unit 130.

Next, the glass, contaminated mud, heated sand, etc. sent from below the partition member 142b enter the third stirring space 122c. Similarly to the first agitation space 122a, the fins 123 are rotated by the rotation of the third rotating body 120c in the third agitation space 122c, so that glass, contaminated mud, heated sand, etc. are mixed. Stir in the wet state. At this time, the contaminated mud and the like and the heated sand removed by the cleaning are smaller than the mesh of the third rotating body 120c, and therefore fall from the third rotating body 120c to the transport device 150.
On the other hand, the cleaned glass is separated from the contaminated mud and heated sand by the inclination of the rotating body 120 and the feeding of the fins 123, and is discharged from the rear of the third rotating body 120c.

  As described above, according to the cleaning device 110 according to the present embodiment, when cleaning the glass, there is no need to clean it using a cleaning liquid or the like. It can be carried out. Accordingly, the cleaning efficiency can be improved and the processing cost can be reduced.

In the above description, the case where the first rotating body 120a, the second rotating body 120b, and the third rotating body 120c of the cleaning device 110 are substantially circular in cross section has been described. However, the present invention is not limited to this case. The cross section may be a polygonal shape such as a regular octagon.
Further, in the above description, the case where the sand sprayed from the sand jet unit 130 is heated sand is described. However, the present invention is not limited to this, and a cleaning material such as normal temperature sand according to the degree of adhesion of the contaminated mud of the glass. May be used.
In the above description, the case where the fin 123 is attached to the inner peripheral surface of the rotating body 120 has been described. However, the present invention is not limited to this case, and the fin 123 may not be attached.

  Moreover, although the sand injection part 130 demonstrated the case where it arrange | positions in the 2nd stirring space 122b in the description mentioned above, you may arrange | position not only in this case but the 2nd rotary body 120b. In this case, the second rotating body 120b is configured by a hollow metal network structure, so that the sand injected from the sand injection section passes through the second rotating body 120b and forms the contaminated mud adhering to the glass. Can be washed. In addition, when the sand injection unit 130 is disposed above the second rotating body 120b, a few percent of the injected sand collides with the network structure of the second rotating body 120b, which reduces the cleaning effect. The structure of the cleaning device 110 can be simplified.

Next, a configuration and processing operation in which the sand used for cleaning is collected, heated again, and reused in the cleaning system 200 will be described.
Sand or the like that has dropped from the mesh of the third rotating body 120 c of the cleaning device 110 falls on the transport device 150. Here, when the degree of adhesion of the cleaned mud contaminated mud is low and does not contain much contaminated mud, the conveying device (conveying unit) 150 conveys it to the heating device 160 and drops it onto the heating surface of the heating device 160. .
The heating device (heating unit) 160 transfers the sand dropped on the heating surface to the vertical transfer device 170 while heating.
The vertical transfer device (vertical transfer unit) 170 puts the sand heated by the heating device 160 into the supply port 127 of the cleaning device 110.
By configuring the cleaning system 200 in this manner, sand used when cleaning is performed by the cleaning device 110 can be collected and reused by being heated again.

  If the sand that has fallen from the third rotating body 120c contains a large amount of contaminated mud, the fallen sand is sprayed and washed in the circulation process, and then dried and heated to high temperature in a heating kettle. Use it.

In addition, although this embodiment demonstrated the case where the sand which heated was used as a cleaning material, it is not restricted to this case. For example, an artificially generated cleaning material may be used.
Moreover, although this embodiment demonstrated the case where a concrete glass is dried and wash | cleaned, it can be used when wash | cleaning a stone and other solid substances. Moreover, although the case where the contaminated mud was removed as an adhering material was described, it may be used when mud, dust, or the like is removed as an adhering material.

  Moreover, although this embodiment demonstrated the case where the washing | cleaning system 200 was comprised including the washing | cleaning apparatus 110, the conveying apparatus 150, the heating apparatus 160, and the vertical conveying apparatus 170, it is not restricted to this case. For example, at least one of the transport device 150, the heating device 160, and the vertical transport device 170 may be integrally formed with the cleaning device 110. That is, at least one of the transport unit 150, the heating unit 160, and the vertical transport unit 170 may be provided in the cleaning device 110.
