Description

  The present invention relates to a water supply type solid matter processing apparatus which is provided at a drain outlet and pulverizes an inputted unground solid matter and discharges the ground ground solid matter together with water.

  As one type of such a water supply type solid material processing apparatus, there is a soot processing apparatus. As a dredger treatment device, a device that supplies water in conjunction with a pulverization operation and makes it difficult to cause clogging of a distribution pipe due to a shortage of supply water has been proposed (for example, see Patent Document 1 below). In the following Patent Document 1, paying attention to simply supplying water in conjunction with the pulverization operation, a large amount of crushed soot is discharged at the initial stage of pulverization, and then the discharged amount of crushed soot is drastically reduced. Yes. Specifically, when a large amount of crushed soot is discharged at the initial stage of pulverization in this way, if the amount of water supplied at the initial stage of pulverization is small, the water pipe is clogged. It is thought that the amount of water to be supplied must be increased. On the other hand, a new soot treatment device has been proposed by devising the driving mode of the crushing means for the purpose of avoiding clogging of the water distribution pipe without using such wasteful water.

  The soot processing device proposed in the following Patent Document 1 is provided with a pulverizing means for pulverizing unground slag by being driven to rotate, and is configured to increase the number of revolutions of the pulverizing means as the pulverization process proceeds. It is a thing. With such a configuration, at the initial stage of pulverization, the amount of pulverized soot discharged is suppressed by suppressing the rotational speed of the pulverizing means, and the water pipe is prevented from being clogged.

JP 2003-260380 A

  By the way, as pulverized non-pulverized varieties, various things such as soft ones, hard ones, fibrous ones and non-fibrous ones are included. Therefore, even if the pulverizing means is driven at a low speed, in the case of unground slag containing a lot of soft ones, a large amount of crushed slag will be discharged at the initial stage of pulverization, which may cause clogging of the water distribution pipe . In order to cope with such a situation, although it is assumed that the rotational speed of the pulverizing means is further reduced and driven at an extremely low speed, the unpulverized jar may contain many soft and hard things, If the rotational speed of the pulverizing means is too low, hard unground slag will be bitten and the pulverizing means will stop. In addition, as described above, the unground slag that is input includes various miscellaneous things, and the input amount may be large or small. Therefore, the same rotational speed control is applied when a relatively large amount of hard material is contained and a large amount of unground slag is introduced, and when a relatively large amount of soft material is contained and a small amount of unground slag is introduced. It may be difficult to deal with.

  On the other hand, if we focus only on the fact that water pipes will not be clogged by crushed culm, the amount of water supplied during pulverization will be increased, and as a result, the concentration of crushed culm will be reduced to ensure fluidity, and clogging of water pipes will be prevented. It is possible to prevent it from happening. However, the amount of unground slag varies, and it is difficult to predict in advance the ratio of soft and hard slag contained in the unground slag. Is extremely difficult, so if we focus only on eliminating clogging of distribution pipes, we have to cope by increasing the amount of water supplied. As described above, the conventional technology cannot achieve both water saving and prevention of clogging of the water distribution pipe. Moreover, the problem which such a prior art encloses is not limited to the cocoon treatment device as an example of the solid material processing device, but also applies to a pressure-fed toilet device that pulverizes solid material including stool.

  The present invention has been made in view of such a problem, and an object thereof is to provide a water supply that is provided at a drain outlet and pulverizes an inputted unground powder and discharges the pulverized solid with water. This type of solid material processing device can achieve both water saving and prevention of clogging of the water distribution pipe, and can perform optimum pulverization control according to the amount and content of unground pulverized solids to be charged. The object is to provide a solids processing apparatus.

  In order to solve the above-mentioned problems, a solids processing apparatus according to the present invention is provided with a drain outlet, pulverizes the unground pulverized solids charged, and discharges the pulverized pulverized solids together with water. A solids inlet for charging unground solids for pulverization, a first storage chamber that communicates with the solids inlet and stores the unground solids that are input, By being driven to rotate, the pulverization means connected to the pulverization means for pulverizing the unpulverized solid material stored in the first storage chamber and the first storage chamber via the communicating portion, and the pulverization pulverized by the pulverization means A second storage chamber having an outlet for discharging the stored crushed solid matter and receiving the stored solid matter through the communicating portion and temporarily storing the crushed solid matter stored in the second storage chamber Discharging means for discharging an object from the discharge port; Control means for controlling the pulverizing means and the discharge means, the control means having a first control means and a second control means, wherein the first control means is more intensive than the second control means. And the control by the second control means is executed after the control by the first control means is performed, and the control means is the first control means. It is configured to be able to regulate the transition from the control by one control means to the control by the second control means.

  In the present invention, the unpulverized solid material charged from the solid material inlet and stored in the first storage chamber is pulverized, sent to the second storage chamber via the communication portion, and temporarily stored. Therefore, even if a soft unground solid is first pulverized at a stroke by the pulverizing means and a large amount of pulverized solid is generated in a short time, the generated large amount of pulverized solid is temporarily stored in the second storage chamber. By doing so, clogging of the water distribution pipe can be prevented. Thus, even if soft unground solid matter is pulverized at once in the initial stage of the pulverization process, it can be temporarily stored in the second storage chamber. It is only necessary to reduce the speed to such an extent that hard unground solids are not bitten, and unnecessary biting of hard unground solids can be avoided. Further, since the discharging means is used when discharging the stored crushed solid matter from the second storage chamber, the pulverized solid matter can be discharged so as not to clog the water distribution pipe and reduce the use of water as much as possible. . In the present invention, the control means is configured to be able to regulate the transition from the control by the first control means to the control by the second control means. The control means continues the control by the first control means by determining the amount of unground solids according to a transition restriction signal input from the outside or according to a predetermined sequence. It is configured to be able to regulate the shift to control by the two control means. By comprising in this way, the rotation speed of a grinding | pulverization means is raised at the stage where comparatively many unground solids remain | survive, a lot of unground solids are grind | pulverized at a stretch, and a lot of ground solids are produced | generated. It becomes possible to suppress this, and it is possible to reliably prevent a large amount of crushed solid matter from flowing into the water distribution pipe and clogging the water distribution pipe.

  In the solid matter processing apparatus according to the present invention, the control means detects the amount of unground solid matter stored in the first storage chamber, and based on the result of the detection, from the control by the first control means. It is also preferable to determine the timing for shifting to the control by the second control means.

  In this preferred embodiment, since the timing for shifting to the control by the second control means is determined based on the result of detecting the amount of the unground solids stored in the first storage chamber, the unstored in the first storage chamber It is possible to determine the transition timing according to the amount of pulverized solid matter. Therefore, for example, when the amount of unground solids stored in the first storage chamber is a certain amount or more, the control by the first control means can be continued, and the amount of unground solids is increased in a large amount. It is possible to suppress a large amount of pulverized solids from being generated at a stretch since the control by the two control means is started.

  In the solid matter processing apparatus according to the present invention, the control unit detects a drive current of a motor that rotationally drives the pulverizing unit, and controls the first control unit based on a change mode of the detected drive current. It is also preferable to determine the transition timing to control by the second control means.

  It is assumed that the drive current of the motor that rotationally drives the crushing means varies depending on the amount of unground solids stored in the first storage chamber. Therefore, in this preferred embodiment, the transition timing is determined based on the mode of change of the driving current of the motor, and the transition timing is reliably determined by a simple configuration without providing a means for separately determining the remaining amount of the unground solid matter. It is devised so that it can be judged.

  The solid matter processing apparatus according to the present invention further includes water supply means for supplying water to the first storage chamber, and at least the control means changes from control by the first control means to control by the second control means. In the process of determining the transition timing, it is also preferable that the amount of water per unit time supplied from the water supply means does not change.

  Since the drive current of the motor that drives the pulverizing means to rotate varies with the amount of unground solids stored in the first storage chamber, the variation factors other than unground solids should be eliminated as much as possible. Is preferred. Therefore, in this preferred embodiment, the supply amount per unit time of the water supplied to the first storage chamber is not changed, thereby further improving the certainty of determination of the transition timing by detecting the drive current of the motor.

  The solid matter processing apparatus according to the present invention further comprises water supply means for supplying water to the first storage chamber, wherein the control means changes from control by at least the first control means to control by the second control means. In the process of determining the transition timing, it is also preferable to acquire the amount of water per unit time supplied from the water supply means and determine the transition timing in consideration of the acquired amount of water.

  Since the drive current of the motor that rotates the grinding means is assumed to fluctuate depending on the amount of unground solids stored in the first storage chamber, the influence of fluctuation factors other than unground solids can be accurately determined. It is preferable to grasp. Therefore, in this preferable aspect, the certainty of determination of the transition timing by detecting the drive current of the motor is further increased by acquiring and taking into consideration the supply amount of water supplied to the first storage chamber per unit time.

  In the solid matter processing apparatus according to the present invention, it is also preferable that the control means repeatedly executes the determination of the transition timing.

  In this preferred embodiment, the judgment of the transition timing is repeatedly executed, so that it is possible to grasp in a timely manner whether or not the unpulverized solid matter has decreased and the transition conditions for the control by the second control means are satisfied. Therefore, the control by the first control means should be continued although the control should be shifted to the control by the second control means, and as a result, it can be avoided that the time required for the entire pulverization process becomes unnecessarily long. The effect can be further enhanced.

  In the solid matter processing apparatus according to the present invention, when the control means determines that it is not the timing to shift from the control by the first control means to the control by the second control means, the rotational speed of the pulverizing means is set. It is also preferable to continue the control by the first control means by lowering.

  In the present invention, relatively soft unground solids are pulverized by the rotational drive control of the pulverizing means by the first control means, and compared by the rotational drive control of the pulverizing means by the second control means following the control by the first control means. It is intended to grind the unhardened solid material. Therefore, when shifting from the control by the first control means to the control by the second control means, the unground solid matter to be pulverized is processed by the control by the first control means, and then the control is transferred to the second control means. Otherwise, a large amount of crushed solid matter may be generated at a stretch in the initial stage of control by the second control means. In addition, as the unpulverized solid, various kinds such as a soft one, a hard one, a fibrous one, and a non-fibrous one are included. In this way, when trying to pulverize unground solids containing various miscellaneous things, soft unground solids are suitable for pulverization by the control by the first control means, and control by the second control means. Hard unground solids are suitable for grinding. On the other hand, the fibrous unpulverized solid is gradually pulverized by the control by the first control means after the soft unpulverized solid and is fed into the second storage chamber. The fibrous crushed solids fed into the second storage chamber are long and bulky compared to other crushed solids that have been crushed. Therefore, when the rotational speed of the pulverizing means is high and the flow velocity in the second storage chamber is high, the pulverized solid matter of fiber that is long and bulky generates eddy currents in the second storage chamber due to its bulkiness. The fibers are easily entangled with each other by the generated vortex. When fibrous ground solids are entangled with each other, they become pill-shaped, and if the pulverized fibrous solids that have become pill-shaped are discharged as they are from the outlet, they cause clogging of the water distribution pipes. Therefore, in this preferred embodiment, when shifting from the control by the first control means to the control by the second control means, it is determined whether or not the transition is made, and the control by the first control means is extended while reducing the rotational speed. In the control by the first control means, the unpulverized solids to be pulverized can be more reliably pulverized, and the fibrous unground pulverized solids that are difficult to pulverize are discharged from the second storage chamber so as not to be entangled with each other. It is possible to discharge sequentially.

  In the solid matter processing apparatus according to the present invention, it is also preferable that the control means does not perform the control by the second control means when it is detected that there is no unground solid matter during the control by the first control means. .

  In this preferred embodiment, the control by the second control means is not performed when it is detected that there is no uncrushed solid matter, so unnecessary rotation drive of the grinding means and supply of water are performed without the unground solid matter. This can be avoided and the water saving effect can be further enhanced.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same components are denoted by the same reference numerals as much as possible in the drawings, and redundant descriptions are omitted.

  First, with reference to FIG. 1, a soot processing device (solid material processing device) according to an embodiment of the present invention will be described. FIG. 1 is a cross-sectional view showing a soot treating apparatus according to an embodiment of the present invention and the entire sink in which the soot treating apparatus is installed.

  As shown in FIG. 1, the soot processing apparatus 1 according to the embodiment of the present invention is installed such that the soot loading port 2 into which the soot is thrown opens at the bottom surface of the sink 4. Further, a faucet 6 is provided in the vicinity of the sink 4 and is configured so that washing water can be supplied from the faucet 6 when the soot processing apparatus 1 crushes and cleans the soot. Has been.

  The soot processing device 1 includes a soot processing chamber 8 (first storage chamber) in which the soot inlet 2 is formed upward, a temporary storage chamber 9 (second storage chamber) provided below the soot processing chamber 8, A rotating plate 10 disposed so as to partition the processing chamber 8 and the temporary storage chamber 9, a motor 12 that is a driving means for rotationally driving the rotating plate 10, and the temporary storage chamber 9 are provided in communication with each other and pulverized. And a soot discharge portion 14 (discharge port) for discharging the soot from the temporary storage chamber 9 to a drain pipe (not shown).

  A fixed blade 16 (pulverizing means, second pulverizing portion) is attached to the inner wall surface of the lower part of the cocoon processing chamber 8. Further, two swing hammers 18 (crushing means, first crushing portion) are attached to the upper surface of the rotating plate 10 so as to be rotatable around a shaft 18a. On the lower surface of the rotating plate 10, blades 20 b (discharge means) for stirring the cleaning water in the temporary storage chamber 9 are attached.

  The soot processing chamber 8 is formed in a substantially truncated cone shape having a circular soot inlet 2 opened upward. Moreover, the dredging inlet 2 also serves as the drain of the sink 4, and the water in the sink 4 enters the dredging chamber 8 through the dredging inlet 2, and drains (not shown) through the dredging outlet 14. It is configured to be drained. Further, a water supply pipe WF (water supply means) is provided so that water can be automatically supplied to the dredging treatment chamber 8. The water supply pipe WF is provided with a water supply valve V1 and a water amount sensor S1. The water supply valve V1 is configured to open and close in response to a control signal from the controller 22. The water amount sensor S1 outputs the detected water amount data to the controller 22.

  The rotating plate 10 is a metal disk that is horizontally supported in the middle between the soot processing chamber 8 and the temporary storage chamber 9. Further, the center of the rotary plate 10 is screwed to the rotary shaft 12 a of the motor 12 and is driven to rotate by the motor 12. Moreover, the two shafts 18a are attached to the rotating plate 10 so that it may penetrate at right angles. The shaft 18a rotatably supports the metal swing hammer 18 on the upper surface side of the rotating plate 10. The swing hammer 18 has a substantially rectangular parallelepiped block shape, and a shaft 18a is passed through one end thereof. Further, the bottom surface of the swing hammer 18 is a flat surface and increases in thickness toward the tip, and the tip is formed in an arc shape having substantially the same curvature as the periphery of the rotating plate 10. The length of the swing hammer 18 is set so that the tip of the swing hammer 18 substantially coincides with the periphery of the rotary plate 10 when the swing hammer 18 is directed outward in the radial direction of the rotary plate 10.

  The state which looked at the rotating plate 10 and the fixed blade 16 from upper direction is shown in FIG. As shown in FIG. 2, a metal fixed blade 16 is attached to the lower inner wall of the soot processing chamber 8 so as to surround the rotating plate 10. The fixed blade 16 has a large number of cutout portions 16a formed at equal intervals in the circumferential direction. The unground slag introduced is crushed in the slag processing chamber 8 by being pushed between the edge of each cutout portion 16 a of the fixed blade 16 and the swing hammer 18. And it is sent into the temporary storage chamber 9 through the cutout part 16a as a communication part.

  As shown in FIG. 2, in this embodiment, the fixed blade 16 provided so that the soot processing chamber 8 (1st storage chamber) may be enclosed as a 2nd grinding | pulverization part, and as a 1st grinding | pulverization part One end side of the swing hammer 18 is penetrated by the shaft 18a, and the other end side is rotatably supported so as to be close to the fixed blade 16 as the second pulverizing portion. When the rotating plate 10 is rotated and a centrifugal force is applied, the unground slag moves toward the fixed blade 16. Then, the swing hammer 18 as the first pulverization unit pulverizes the unpulverized soot by pressing it against the fixed blade 16 as the second pulverization unit. Therefore, the force with which the swing hammer 18 presses the unground slag against the fixed blade 16 increases or decreases according to the rotational speed of the rotating plate 10. Specifically, if the rotation speed of the rotating plate 10 is low, the force with which the swing hammer 18 presses the unground slag against the fixed blade 16 becomes weak, so that the relatively soft unsmashed slag is crushed. On the other hand, if the rotational speed of the rotating plate 10 is high, the force with which the swing hammer 18 presses the unground slag against the fixed blade 16 becomes strong, so that the relatively hard unsmashed slag is crushed.

  In the swing hammer 18 shown in FIG. 2, the force for pressing the non-pulverized scissors against the fixed blade 16 regardless of the rotation direction of the rotating plate 10 depends only on the rotational speed. It is also preferable to vary the force of pressing against the fixed blade 16. A preferred example is shown in FIG. The swing hammer 181 shown in FIG. 3 has an inclined surface 181a on the other end side (outer side). When the inclined surface 181 a is formed, a portion that is far away and a portion that is close when approaching the fixed blade 16 are formed, and the force that presses the unground slag against the fixed blade 16 varies depending on the rotation direction of the rotating plate 10. In the case of the example shown in FIG. 3, when the rotating plate 10 is rotated in the direction of the arrow D <b> 1, the force pressing the unground slag against the fixed blade 16 is weakened, and when the rotating plate 10 is rotated in the direction of the arrow D <b> 2 The force to press on is strengthened. By doing in this way, it can be comprised so that the escape action of a non-pulverized soot may differ with the rotation directions of the rotating plate 10. FIG.

  FIG. 4 shows another example in which the unmilled soot escape action is different depending on the rotation direction of the rotary plate 10. FIG. 4 is a view showing a swing hammer 182 according to another example in which the escape action of unground slag varies depending on the rotation direction of the rotary plate 10, and is a view of the rotary plate 10 as viewed from the side. . As shown in FIG. 4, the swing hammer 182 is configured to have different heights in the rotation direction so that the height of one end 182a is low and the height of the other end 182b is high. It is configured. With this configuration, when the rotating plate 10 rotates in the direction of the arrow D3, the lower end portion 182a tries to catch the unground scum, so that the unsmashed slag becomes easy to escape. On the other hand, when the rotating plate 10 rotates in the direction of the arrow D4, the higher end 182b tries to catch the unmilled soot.

  By adopting the swing hammers 18, 181 and 182 as described above, it is possible to smash the soft unground slag without pulverizing the hard unground slag depending on the rotation speed and the rotation direction of the rotating plate 10. Therefore, it functions as an adjusting means that does not grind hard unmilled soot but soft unmilled soot.

  Then, the structure of the temporary storage chamber 9 provided in the lower part of the soot processing chamber 8 and the soot discharge part 14 formed there is demonstrated, referring FIG. FIG. 5 is a cross-sectional view taken along the line II-II in FIG. 1, and is a perspective cross-sectional view showing the temporary storage chamber 9 provided in the lower portion of the soot processing chamber 8.

  As shown in FIG. 5, the soot discharging part 14 is a cylindrical pipe line formed in the vicinity of the bottom surface of the temporary storage chamber 9 in the horizontal direction, and its tip is connected to a drain pipe (not shown). ing. In addition, the basket discharging portion 14 is formed so as to be directed substantially in the tangential direction of a circle centering on the rotation shaft 12 a of the motor 12 that rotates the rotating plate 10. For this reason, when the rotating shaft 12a is rotated in the direction of arrow D5 in FIG. 5, the wash water in the temporary storage chamber 9 is agitated by the blades 20b, and the drainage from the soot discharge portion 14 is suppressed. As a result, the cleaning water is easily retained in the temporary storage chamber 9. On the other hand, when the rotating shaft 12a is rotated in the direction of arrow D6, drainage of the wash water from the soot discharge portion 14 is promoted, and the wash water in the temporary storage chamber 9 is quickly discharged.

  Returning to FIG. 1, the soot processing apparatus 1 has a controller 22 as control means, and the controller 22 operates the motor 12 based on the detection signal of the magnetic detection element 24 provided in the soot slot 2. It is configured. Furthermore, the dredge processing apparatus 1 is struck by the controller 22 in a predetermined case, and the lamp 25 which is a notification means for notifying the user of the arrival of the cleaning time, and the control from the first control means 22a to the second control means 22b. And a switch 28 for restricting the transition.

  The controller 22 is configured to execute the crushing operation of the soot processing device 1 based on the detection signal of the magnetic detection element 24. The controller 22 has a first control means 22a and a second control means 22b. The first control means 22a and the second control means 22b rotate the motor 12 in different modes. The first control means 22a and the second control means 22b are configured to selectively operate. The first control means 22a and the second control means 22b output a control signal to the motor 12 to control its rotation direction and speed, and the current value detected by the current sensor S2 that detects the drive current of the motor 12 Data is acquired. A specific control mode by the first control unit 22a and the second control unit 22b will be described later. Specifically, the controller 22 includes a microprocessor, a memory, and a program (not shown) stored therein.

  Next, an example of the driving sequence of the heel processing apparatus 1 will be described with reference to the timing chart shown in FIG. In the timing chart shown in FIG. 6, the horizontal axis indicates time, and the vertical axis indicates the rotation speed of the motor 12. As for the rotation of the motor 12, r1, r2, r3, r4, r5 are forward rotations (directions of arrows D6 in FIG. 5), and r1 ′, r2 ′, r5 ′ are reverse rotations (directions of arrows D5 in FIG. 5). ). Further, the control by the first control means 22a is executed from time t1 to time t11, the control by the second control means 22b is executed from time t11 to time t12, and the control by the controller 22 is executed from time t12 to time t17. To be executed.

  From time t1 to time t1, the motor 12 is driven at the rotational speed r1 '. Since the rotation speed r1 ′ is a rotation speed suitable for pulverizing soft unground slag, relatively soft ones of the unground slag introduced into the slag processing chamber 8 are pulverized and temporarily stored in the temporary storage chamber 9. It is sent to. Since the rotation at the rotation speed r1 ′ is the reverse rotation (the direction of the arrow D5 in FIG. 5), the discharge amount of the crushed soot discharged from the temporary storage chamber 9 is reduced and sent to the temporary storage chamber 9 The crushed soot is gradually discharged.

  From time t2 to time t3, the drive of the motor 12 is stopped. Water is supplied at a constant flow rate (for example, 6 L / min) from time t2 to time t3 when the driving of the motor 12 is stopped. Accordingly, water is stored in the temporary storage chamber 9.

  From time t3 to time t4, the motor 12 is driven at the rotational speed r1. Since the rotational speed r1 is a rotational speed suitable for pulverizing soft unground slag, a relatively soft one of the unground slag introduced into the slag processing chamber 8 is pulverized to the temporary storage chamber 9. It is sent. Since the rotation at the rotation speed r1 is a normal rotation (in the direction of arrow D6 in FIG. 5), the discharged amount of the crushed soot discharged from the temporary storage chamber 9 is a normal state (the discharged amount is higher than the reverse rotation). State), and the crushed soot sent to the temporary storage chamber 9 is discharged. From time t1 to time t4, the operation is in the low-speed drive mode.

  From time t4 to t5, the motor 12 is driven at the rotation speed r2. Since the rotational speed r2 is a rotational speed suitable for pulverizing unground slag that is slightly difficult to pulverize, among the unground slag that has been put into the slag processing chamber 8, those that are slightly difficult to pulverize are pulverized temporarily. It is sent to the storage chamber 9. Since rotation at the rotation speed r2 is forward rotation (in the direction of arrow D6 in FIG. 5), the discharged amount of the crushed soot discharged from the temporary storage chamber 9 is a normal state (the discharged amount is higher than the reverse rotation). State), and the crushed soot sent to the temporary storage chamber 9 is discharged.

  From time t5 to time t6, the drive of the motor 12 is stopped. Water is supplied at a constant flow rate (for example, 6 L / min) from time t5 to time t6 when the driving of the motor 12 is stopped. Accordingly, water is stored in the temporary storage chamber 9. From time t5 to time t6, water is stored in the temporary storage chamber 9 to reduce the concentration of the crushed soot and increase the fluidity, so that the next motor 12 is driven to effectively discharge the crushed soot.

  From time t6 to time t7, the motor 12 is driven at the rotational speed r2. Since the rotational speed r2 is a rotational speed suitable for pulverizing unground slag that is slightly difficult to pulverize, among the unground slag that has been put into the slag processing chamber 8, those that are slightly difficult to pulverize are pulverized temporarily. It is sent to the storage chamber 9. Since rotation at the rotation speed r2 is forward rotation (in the direction of arrow D6 in FIG. 5), the discharged amount of the crushed soot discharged from the temporary storage chamber 9 is a normal state (the discharged amount is higher than the reverse rotation). State), and the crushed soot sent to the temporary storage chamber 9 is discharged.

  From time t6 to time t7, the presence / absence of unmilled soot is determined. The presence / absence of unmilled soot is determined on the basis of the change in the drive current of the motor 12. If the fluctuation current of the drive current of the motor 12 is large, it is determined that the unpulverized soot still exists, and if the fluctuation width of the drive current of the motor 12 is small, it is determined that there is no unpulverized soot. An example of the drive current of the motor 12 is shown in FIG. In the example shown in FIG. 7, it is assumed that in the area AR1 between the time t6 and the time t7, the fluctuation width of the drive current of the motor 12 is large, and the unmilled soot still exists. On the other hand, in the area AR2 between time t10 and time t13, the fluctuation width of the drive current of the motor 12 is small, and it is assumed that there is no uncrushed wrinkle. Therefore, if the runout width in the area AR2 is reached from the time t6 to the time t7, it is determined that there is no uncrushed soot. If it is determined from time t6 to time t7 that there is no longer any crushed soot, the remaining control by the first control means 22a (time t7 to time t11) and the control by the second control means 22b (time t11 to time t12). ) And control from time t12 is executed.

  Returning to FIG. 6, the drive of the motor 12 is stopped from time t7 to time t8. From time t7 to time t8 when the driving of the motor 12 is stopped, water is supplied at a constant flow rate (for example, 6 L / min). Accordingly, water is stored in the temporary storage chamber 9.

  From time t8 to time t9, the motor 12 is driven at the rotational speed r2 '. Since the rotation speed r2 ′ is a rotation speed suitable for pulverizing unground slag that is slightly difficult to pulverize, the unsmashed slag that has been put into the slag processing chamber 8 is pulverized. It is sent to the temporary storage chamber 9. Since the rotation at the rotation speed r2 ′ is the reverse rotation (the direction of the arrow D5 in FIG. 5), the discharge amount of the crushed soot discharged from the temporary storage chamber 9 is reduced and sent to the temporary storage chamber 9 The crushed soot is gradually discharged. By the operation from time t8 to time t9, the caught fibrous crushed culm is discharged.

  From time t9 to time t10, the drive of the motor 12 is stopped. From time t9 to time t10 when the driving of the motor 12 is stopped, water is supplied at a constant flow rate (for example, 6 L / min). Accordingly, water is stored in the temporary storage chamber 9.

  From time t10 to time t11, the motor 12 is driven at the rotation speed r3. Since the rotational speed r3 is a rotational speed suitable for discharging the fiber unpulverized soot that is hard to be crushed without being entangled, among the unground slag introduced into the soot processing chamber 8, the pulverized remaining fiber Quality material is fed into the temporary storage chamber 9. Since the rotation at the rotation speed r3 is forward rotation (in the direction of arrow D6 in FIG. 5), the discharged amount of the crushed soot discharged from the temporary storage chamber 9 is a normal state (the discharged amount is higher than the reverse rotation). State), and the crushed soot sent to the temporary storage chamber 9 is discharged.

  From time t10 to time t11, the presence / absence of unmilled soot is determined. The presence / absence of unmilled soot is determined on the basis of the change in the drive current of the motor 12. If the fluctuation current of the drive current of the motor 12 is large, it is determined that the unpulverized soot still exists, and if the fluctuation width of the drive current of the motor 12 is small, it is determined that there is no unpulverized soot. In the example shown in FIG. 7, it is assumed that in the area AR1 between the time t6 and the time t7, the fluctuation width of the drive current of the motor 12 is large, and the unmilled soot still exists. On the other hand, in the area AR2 between time t10 and time t13, the fluctuation width of the drive current of the motor 12 is small, and it is assumed that there is no uncrushed wrinkle. Therefore, if the runout width in the area AR2 is reached at a certain stage from the time t10 to the time t13, it is determined that there is no uncrushed soot. If it is determined from time t10 to time t11 that there is no longer any crushed soot, the remaining control (to time t11) by the first control means 22a is skipped, and the control by the second control means 22b (time t11 to time t11). The process proceeds to t12). In addition, when it is determined that unground slag exists, the determination of the presence / absence of unground slag is continuously repeated.

  Returning to FIG. 6, from time t11 to time t12, the motor 12 is driven at the rotational speed r4. The rotation speed r4 is a rotation speed suitable for pulverizing hard unground slag that is difficult to pulverize. Therefore, among the unground slag that has been put into the slag processing chamber 8, a hard one that is difficult to pulverize is pulverized temporarily. It is sent to the storage chamber 9. Since the rotation at the rotation speed r3 is a normal rotation (in the direction of arrow D6 in FIG. 5) and a high-speed rotation, the amount of crushed soot discharged from the temporary storage chamber 9 is large, and the temporary storage chamber 9 is discharged. The sent crushed rice cake is discharged.

  From time t12 to time t13, the motor 12 is driven at the rotation speed r5. The rotation speed r5 is a rotation speed suitable for pulverizing hard unground slag that is difficult to pulverize. Therefore, among the unground slag introduced into the slag processing chamber 8, a hard one that is difficult to pulverize or a shape that is difficult to pulverize ( Spheres) are crushed and fed into the temporary storage chamber 9. Since the rotation at the rotation speed r5 is normal rotation (in the direction of arrow D6 in FIG. 5) and high-speed rotation, the amount of crushed soot discharged from the temporary storage chamber 9 is large, and the temporary storage chamber 9 is discharged. The sent crushed rice cake is discharged.

  From time t13 to time t14, the drive of the motor 12 is stopped. From time t13 to time t14 when the drive of the motor 12 is stopped, water is supplied at a constant flow rate (for example, 6 L / min). Accordingly, water is stored in the temporary storage chamber 9.

  From time t14 to time t15, the motor 12 is driven at the rotational speed r5 '. The rotation speed r5 ′ is a rotation speed suitable for pulverizing hard unground slag that is difficult to pulverize. Therefore, among the unground slag that has been put into the slag processing chamber 8, it is hard to pulverize or is difficult to pulverize. The (sphere) material is crushed and fed into the temporary storage chamber 9. Since the rotation at the rotation speed r5 ′ is reverse rotation (in the direction of arrow D5 in FIG. 5) and high-speed rotation, the amount of crushed soot discharged from the temporary storage chamber 9 is slightly larger, and the temporary storage chamber 9 The crushed rice cake sent to is discharged.

  From time t15 to time t16, the drive of the motor 12 is stopped. Water is supplied at a constant flow rate (for example, 6 L / min) from time t15 to time t16 when the driving of the motor 12 is stopped. Accordingly, water is stored in the temporary storage chamber 9.

  From time t16 to time t17, the motor 12 is driven at the rotation speed r5. The rotation speed r5 is a rotation speed suitable for pulverizing hard unground slag that is difficult to pulverize. Therefore, among the unground slag introduced into the slag processing chamber 8, a hard one that is difficult to pulverize or a shape that is difficult to pulverize ( Spheres) are crushed and fed into the temporary storage chamber 9. Since the rotation at the rotation speed r5 is normal rotation (in the direction of arrow D6 in FIG. 5) and high-speed rotation, the amount of crushed soot discharged from the temporary storage chamber 9 is large, and the temporary storage chamber 9 is discharged. The sent crushed rice cake is discharged.

  By executing the control as described above, the amount of crushed soot discharged over time is leveled as indicated by L1 in FIG. On the other hand, if the motor 12 is controlled at the same rotational speed from the beginning as in the prior art, a large amount of crushed soot is discharged at the initial stage as in L3. Moreover, if the discharge means is not specially devised, the discharge amount of the crushed soot of about L2 can only be reduced even if the rotational speed of the motor 12 is reduced. Therefore, by executing the control as described above using the soot processing apparatus 1 as in the present embodiment, the discharge amount of the ground soot can be reliably leveled as indicated by L1.

  In the present embodiment, water is supplied at a constant flow rate (for example, 6 L / min). However, even if the amount of water supply is changed, the amount of change is detected by the water amount sensor S1. The controller 22 preferably reflects the amount of water in the determination of the presence or absence of unground slag in the determination of the transition from the first control means 22a to the second control means 22b.
