Next, the operation of the suction pump 1 configured as described above will be described.
First, when a dry-type collected material such as powder is collected and discharged, a suction pipe (not shown) is connected to the suction pipe 7 and extended to a position for sucking the suction-collected material. Next, when the on-off valves 181, 182, 161, 163, 241, 261, 262, 263, 264 are closed and the on-off valves 141, 142, 171, 191, 192 are opened and the blower 10 is driven, the suction is performed. The mouth communicates with the receiver tank 3 through the pressure increasing / decreasing pipe 14, the cyclone dust collector 12 and the bag filter 15, and the discharge port communicates with the atmosphere through the discharge pipe 17 and the dust collector 11.

  Thereby, since the blower 10 sucks the air in the receiver tank 3 and discharges it to the atmosphere, it is possible to make the pressure in the receiver tank 3 negative. When the pressure in the receiver tank 3 falls below a certain level, the open / close valve 71 is opened, and the dry-type collected material is sucked and collected into the receiver tank 3 through the suction pipe and the suction pipe 7. At this time, a part of the dry collected material collected in the receiver tank 3 through the pressure-reducing pipe 14 is sucked to the blower 10 side, and the dry collected material is collected by the cyclone dust collector 12 and the bag filter 15.

  Further, by opening the hatch 27 of the receiver tank 3 from the silo of the cement factory, it is possible to accommodate the dry-type collected material (cement) by gravity.

  In this way, the dry-collected materials are sequentially sucked and collected in the receiver tank 3, and when a certain amount is reached, the sucking and collecting operation of the dry-collected materials is stopped and returned to the running state. Then, the suction pump 1 is moved to the discharge place, a pumping pipe (not shown) is connected to the recovered material discharge pipe 8, and extended to the discharge position, and then the tilting cylinder 22 is extended to operate the receiver tank 3 Is tilted around the tilting pin 2a.

  Next, the opened on-off valve 141 is closed, and the on-off valves 163, 261, 262, 263, 264 are opened. Thus, the discharge port of the compressor 25 communicates with the air chamber partitioned by the canvas 51 through the compressed air supply pipe 26, the aeration pipe 26 a, and the air introduction pipe 52. Further, the discharge port of the compressor 25 communicates with the recovered product discharge pipe 8 through the compressed air supply pipe 26, the ejector pipe 26b, and the ejector pipe 82 (see FIG. 2) provided in the recovered product discharge pipe 8. Further, the discharge port of the compressor 25 communicates with the receiver tank 3 through the compressed air supply pipe 26 and the pressurizing pipe 26c.

  Thus, when the compressor 25 is driven, pressurized air is supplied to the air chamber partitioned by the canvas 51 through the compressed air supply pipe 26, the aeration pipe 26 a, and the air introduction pipe 52. The dry recovery material is fluidized by the pressurized air supplied through the canvas 51. The compressor 25 sucks outside air and supplies pressurized air to the receiver tank 3 through the compressed air supply pipe 26 and the pressurization pipe 26c. If the on-off valve 81 of the recovered material discharge pipe 8 is opened in this state, the fluidized dry recovered material is pumped to a discharge position such as a silo through the recovered material discharge pipe 8 and the pressure feed pipe.

  At this time, by supplying pressurized air to the ejector piping 82 (see FIG. 2) provided in the recovered material discharge piping 8, discharge of the dry-type recovered material in the recovered material discharge piping 8 and the pressure feed pipe due to the ejector effect. Is promoted.

  On the other hand, when recovering wet waste such as sludge and discharging it, the nut 45 is loosened with respect to the fixing bolt 44, and the fixing bolt 44 is rotated around the pin 43a to cut out the notch portion 54a of the locking bracket 54. The first chamber gate 5A is removed from the chamber 41. Next, after gripping the second chamber gate 5B and arranging the second chamber gate 5B in the rear end opening of the chamber 41 so that the fixing bolt 44 and the locking bracket 54 face each other, each fixing bolt 434 The second chamber gate 5B is fixed to the chamber 41 by rotating around the pin 43a and inserting it into the notch portion 54a of the corresponding locking bracket 54 and screwing the nut 45 into the fixing bolt 44, respectively. Further, a suction pipe (not shown) is connected to the suction pipe 7 and extends to a position for sucking the suction collected material.

  In this state, if the on-off valves 163, 181, 182, 191, 192, 241, 261, 262, 263, 264 are closed and the on-off valves 141, 142, 161, 171 are opened to drive the blower 10, The air in the receiver tank 3 is sucked through the pressure increasing / decreasing pipe 14, and the inside thereof is maintained at a negative pressure. Thereafter, if the on-off valve 71 is opened, the wet collected material is sucked and collected in the receiver tank 3 through the suction pipe and the suction pipe 7.

  A part of the wet collected material collected in the receiver tank 3 through the pressure increasing / decreasing pipe 14 is sucked to the blower 10 side, and the wet collected material is collected by the cyclone dust collector 12.

  In this way, when the wet collection material is sucked and collected in the receiver tank 3 and reaches a certain amount, the suction collection operation of the wet collection material is stopped and returned to the running state. Then, after moving the suction pump 1 to the discharge site, an on-off valve 81 is provided and a pump pipe (not shown) is connected to the recovered product discharge pipe 8 (see FIG. 2) connected to the tailgate 4. Connect and extend to the discharge position.

  Next, when the on-off valves 142, 171, 191, 192, 261, 262, 263, and 264 are closed and the on-off valves 161, 163, 181, and 182 are opened and the blower 10 is driven, the blower 10 is connected to the suction pipe. 162, air is sucked through the suction pipe 16, and pressurized air is supplied to the receiver tank 3 through the discharge pipe 17, the tank separator 20, the pressure pipe 18, and the pressure increase / decrease pipe 14. Thereby, the receiver tank 3 is pressurized. If the on-off valve 81 of the recovered material discharge pipe 8 is opened in this state, the wet recovered material sucked and collected in the receiver tank 3 is pumped to the discharge position via the recovered material discharge pipe 8 and the pressure feed pipe.

  Further, the opening / closing cylinder 23 is extended, the tailgate 4 is rotated upward around the hinge pin 3a to open the rear end opening of the receiver tank 3, the tilting cylinder 22 is extended, and the receiver tank 3 is tilted. By tilting backward around the pin 2a, the wet recovered material can be discharged by gravity.

  As described above, when the first chamber gate 5A is attached in place of the second chamber gate 5B corresponding to the dry-type recovered material sucked and collected in the receiver tank 3, or the second chamber is corresponding to the wet-recovered material. When the gate 5B is attached in place of the first chamber gate 5A, it can be easily attached and detached by rotating the nut 45 with respect to a small number of fixing bolts 44, and the chamber gate 5 corresponding to the suction target is changed in a short time. Therefore, it is possible to quickly perform the suction recovery operation.
