  First, an embodiment shown in FIGS. 1 to 4 will be described.

  1 and 2 show a liquid processing apparatus, and a cyclone separator 13 is installed on a frame 11 movable by a caster 10 via a frame 12.

  The cyclone separator 13 is provided with a tangential liquid inlet 15 on the side surface of the cylindrical body 14, a liquid outlet 16 at the center of the upper surface of the cylindrical body 14, and settled at the lower part of the cylindrical body 14. The product discharge port 17 is provided, and the liquid introduced into the cylindrical body 14 from the liquid inlet 15 is swirled to separate the liquid and impurities such as sludge in the liquid due to the difference in mass. The liquid is taken out from the liquid outlet part 16, and the impurities are allowed to settle in the lower part of the cylindrical main body part 14 and discharged from the precipitate discharge port part 17 as a precipitate.

  An on-off valve 18 for taking out the liquid is provided in a conduit for taking out the liquid from the liquid outlet 16 of the cyclone separator 13. The liquid extraction opening / closing valve 18 is a manual valve that opens and closes the ball valve body in the valve body by rotating the lever 18L.

  A cylindrical sediment container 21 for storing the sediment that settles in the cyclone separator 13 is connected to the sediment discharge port 17 of the cyclone separator 13 through an inlet 22 at the center of the upper surface thereof.

  The outlet 23 provided at the lower end of the sediment container 21 is connected to an on-off valve 24 for discharging sediment. The on-off valve 24 for discharging sediment is a manual valve that opens and closes the ball valve body in the valve body by rotating the lever 24L.

  A sediment discharge pipe 25 is connected to the lower side of the on-off valve 24 for discharging the precipitate, and a recovery container 26 is accommodated inside the gantry 11 so as to face the sediment discharge pipe 25.

  A monitoring device 31 is installed on the frame 12 on the gantry 11. As shown in FIGS. 3 and 4, the monitoring device 31 is provided with a push button switch 33 and a timer 34 for setting a filtration time in a control box 32, and a rotation as a warning means on the upper side of the control box 32. A light 35 is installed.

  The rotating lamp 35 operates at the end of the filtration time set by the timer 34, and opens and closes the on-off valves 18 and 24 for liquid extraction and sediment discharge to move from the sediment container 21 into the recovery container 26. This is a so-called patrite that gives a warning instruction to collect the precipitate and also gives a warning instruction to discard the precipitate in the collection container 26 and empty it.

  As shown in FIG. 4, a timer circuit 37 in which a push button switch 33 and a timer relay coil 34rc are connected in series, and a rotating lamp operating circuit 38 having a timer relay normally open contact 34rs are connected to a power source 36, respectively. ing.

  When the timer relay coil 34rc is excited at the timing set by the filtration time, the timer relay normally open contact 34rs is closed, the rotating lamp operating circuit 38 is activated, and the flashing of the rotating lamp 35 is started. On the other hand, when the operator pushes the push button switch 33, the timer circuit 37 is released, the timer relay normally open contact 34rs is also opened, and the blinking of the rotating lamp 35 is stopped.

  Next, the function and effect of the embodiment shown in FIGS. 1 to 4 will be described.

  Open and close the on / off valve 18 for taking out the liquid and close the on / off valve 24 for discharging the sediment, so that the liquid discharged from the machine tool or the like is tangent to the inside of the cylindrical body 14 from the liquid inlet 15. When supplied from the direction, the liquid swirls inside the cylindrical body 14.

  Impurities such as sludge in the liquid are heavier than the liquid, so they settle while turning along the inner peripheral wall surface of the cylindrical main body 14, and the relatively light liquid flows out from the liquid outlet 16 at the center. Therefore, impurities are separated from the liquid and filtered. After the impurities settle down to the lower part of the cylindrical main body 14, they are stored in the sediment container 21 through the sediment discharge port 17, and are accumulated as precipitates inside the sediment container 21.

  In this way, impurities are filtered out from the liquid by the cyclone separator 13, and when the filtration time reaches the timing set by the timer, the monitoring device 31 works, the timer relay coil 34rc is excited, and the timer relay normally open contact When the 34rs is closed, the revolving light 35 blinks. Therefore, the operator who visually recognizes the blinking of the revolving light 35 operates the on-off valves 18 and 24 for liquid removal and sediment discharge to operate the liquid discharge. The on-off valve 18 is switched from the open state to the closed state, and the sediment discharge on-off valve 24 is switched from the closed state to the open state.

  As a result, the internal pressure of the cyclone separator 13 is increased, and the sediment accumulated in the sediment container 21 is pushed out by the internal pressure, and is recovered from the sediment container 21 to the recovery container 26. When such recovery is completed, the liquid discharge on-off valve 18 is operated to return from the closed state to the open state, and the precipitate discharge on-off valve 24 is operated to return from the open state to the closed state.

  At this time, if the collection container 26 is filled with the collected precipitate and liquid, the collection container 26 is removed from the gantry 11 and the precipitate and liquid in the collection container 26 are discarded and emptied. To do.

  In this way, the rotating lamp 35 operates at the timing set by the timer 34 of the monitoring device 31 and instructs to collect the sediment from the sediment container 21 into the collection container 26. Opening and closing valves 18 and 24 for taking out and discharging sediment are operated to open and close the sediment from the sediment container 21 into the recovery container 26, and discard the sediment in the recovery container 26 and dispose of the sediment in the recovery container 26. It is possible to ensure that the operation of emptying the container is performed at a predetermined timing, and it is possible to reliably prevent such an operation from being neglected and neglected and to operate the sediment container 21 with the sediment filled by the operator's carelessness. The problem of impairing the function of the cyclone separator 13 when the operation is continued can be prevented, and the cyclone separation function can be maintained normally. Furthermore, since the warning is given to discard the sediment in the recovery container 26 and empty it, the recovery container 26 can be prevented from overflowing with the precipitate and liquid. Further, since the rotating light 35 can be confirmed from a distance, a warning to the worker can be ensured.

  Next, another embodiment shown in FIGS. 5 to 7 will be described.

  The cyclone separator 13 rotates the liquid introduced from the liquid inlet part 15 into the cylindrical body part 14 to separate the liquid and impurities such as sludge in the liquid due to the difference in mass. The impurities are taken out from the portion 16 and settled in the lower part of the cylindrical body portion 14 and discharged as a precipitate from the precipitate discharge port portion 17.

  An on-off valve 18 for taking out the liquid is provided in a conduit for taking out the liquid from the liquid outlet 16 of the cyclone separator 13. The liquid take-off opening / closing valve 18 is an automatic valve that opens and closes the ball valve body in the valve body by the valve operating means 52.

  A cylindrical sediment container 21 for storing the sediment that settles in the cyclone separator 13 is connected to the sediment discharge port 17 of the cyclone separator 13 through an inlet 22 at the center of the upper surface thereof.

  The outlet 23 provided at the lower end of the sediment container 21 is connected to an on-off valve 24 for discharging sediment. The on-off valve 24 for discharging sediment is a manual valve that opens and closes the ball valve body in the valve body by the valve operating means 52.

  A sediment discharge pipe 25 is connected to the lower side of the on-off valve 24 for discharging the precipitate, and a recovery container 26 is accommodated inside the gantry 11 so as to face the sediment discharge pipe 25.

  A monitoring device 31 is installed on the frame 12 on the gantry 11. As shown in FIG. 7, the monitoring device 31 includes a control panel 51 to which a timer 34 for setting a filtration time is connected, and an on-off valve 18 for liquid extraction and sediment discharge at a timing set by the timer 34. , 24 are automatically opened and closed to automatically instruct that the sediment S is collected from the sediment container 21 into the collection container 26, and the number of operations of these valve actuation means 52 is counted. A rotating lamp 35 as a warning means for warning that the sediment S and the liquid L recovered from the sediment container 21 into the recovery container 26 by operating the control panel 51 are discarded and the recovery container 26 is emptied. It is provided.

  The timer 34 switches the depositing on-off valve 18 from the open state to the closed state, and switches the sediment discharge on-off valve 24 from the closed state to the open state, thereby causing the sediment S from the sediment container 21 to the recovery container 26. The timing to collect the is set.

  Each valve operating means 52 that operates the on-off valves 18 and 24 for discharging liquid and discharging sediment is an electromagnetic valve 53 controlled by a signal from a control panel 51, and an air cylinder controlled by the electromagnetic valve 53 54, a rack 55 that moves forward and backward by the air cylinder 54, and a pinion 56 that meshes with the rack 55 and rotates forward and backward by the rack 55 to open and close the ball valve body in the valve body.

  Next, the function and effect of the embodiment shown in FIGS. 5 to 7 will be described.

  Open the on / off valve 18 for liquid removal, close the on / off valve 24 for sediment discharge, and tangentially feed the liquid pumped up by the vortex pump 41 from the liquid inlet 15 into the cylindrical body 14. When supplied more, the liquid swirls inside the cylindrical body 14.

  Impurities such as sludge in the liquid are heavier than the liquid, so they settle while turning along the inner peripheral wall surface of the cylindrical main body 14, and the relatively light liquid flows out from the liquid outlet 16 at the center. Therefore, impurities are separated from the liquid and filtered. After the impurities settle down to the lower part of the cylindrical main body 14, they are stored in the sediment container 21 through the sediment discharge port 17, and are accumulated as precipitates inside the sediment container 21.

  In this way, impurities are filtered out from the liquid by the cyclone separator 13, and when the filtering time reaches the timing set by the timer 34, the valve operating means 52 of the monitoring device 31 operates to switch the electromagnetic valve 53 to air. The cylinder 54 is operated, the rack 55 and the pinion 56 are operated, and the on-off valves 18 and 24 for liquid extraction and sediment discharge are automatically operated to switch the on-off valve 18 for liquid extraction from the open state to the closed state. At the same time, the on-off valve 24 for discharging sediment is switched from the closed state to the open state.

  As a result, the internal pressure of the cyclone separator 13 is increased, and the sediment accumulated in the sediment container 21 is pushed out by the internal pressure, and is recovered from the sediment container 21 to the recovery container 26. At the timing set in such a time that the recovery operation is completed, the liquid discharge on-off valve 18 is returned from the closed state to the open state, and the sediment discharge on-off valve 24 is changed from the open state to the closed state. Returned.

  Such a collection operation is counted by a counter (not shown) in the control panel 51, and it can be seen that the collection container 26 is filled with the collected precipitate S and liquid L by the number of counts. The revolving light 35 blinks according to the number of counts. An operator who confirms the blinking of the rotating lamp 35 takes out the collection container 26 from the gantry 11 and discards the precipitate S and the liquid L.

  In this way, the valve operating means 52 automatically opens and closes the on-off valves 18 and 24 for liquid extraction and sediment discharge at the timing set by the timer 34 of the monitoring device 31, so that it is recovered from the sediment container 21. The sediment is automatically and reliably collected in the container 26 at a predetermined timing, so that the function of the cyclone separator 13 can be kept normal, and the rotating lamp 35 collects the precipitate from the sediment container 21 into the collection container 26. Therefore, the recovery container 26 can be prevented from overflowing with the precipitate S and the liquid L. Further, since the rotating light 35 can be confirmed from a distance, a warning to the worker can be ensured.

  In the present invention, the rotating lamp 35 may be operated by the timer 34 at a predetermined timing, and the operator who has confirmed the operation of the rotating lamp 35 may manually operate the on-off valves 18 and 24. Further, as the warning means, in addition to the rotating lamp 35, a non-rotating flashing lamp may be used, or a warning means by sound such as an alarm or a buzzer may be used.
