6 is an overall perspective view of the vertical dewatering device and the pure water separating device according to the present invention continuously arranged vertically.

As shown in FIG. 6, when the discharged materials are collected in the primary reserving hopper 8 after a predetermined time, the level meter 8 ′ instructs the controller to control the upper level of the quantity of rotary discharge valve 9. When the water-containing wood is discharged while the water of a certain capacity is stored in the appropriate water storage hopper 61 and the level 66 indicates the upper level, the controller 120 of the primary water storage hopper 8 is opened. Close the rotary discharge valve (9).

Then, while recognizing that the rehydration apparatus according to the present invention is waiting in the horizontal position by the detection of the signal of the upper touch bar limit 60, which is the standby position, the rotary discharge valve 67 of the reinforcement storage hopper 61 is opened a certain amount When the reservoir hopper level meter 66 transmits a lower signal to the control unit 120, the reservoir hopper 61 rotary discharge valve 67 is closed. The repetitive work is performed by the level of the storage hopper 61.

Moisture contained in the discharged water from the above process is detected by the load cell 48 provided on the lower surface of the drive complex tank 30 to give a time for 2 minutes by the dehydration motor 42, the cylinder When the drum 10 rotates clockwise at a low speed to a high speed, moisture contained in the resin flows out of the mash screen 11 of the cylindrical drum 10 to flow into the drain pipe 39 of the driving composite tank 30. When the 2 minute time is completed, the dehydration motor 42 stops and detects an average value. Then, the water detector 62 moves forward by the water meter 62 cylinder forward valve 64 and measures for 10 seconds. When the reversed by 65), the measured value is sent to the control unit 120, and when the target value (7% or less) is reached, the low speed gear motor 51 rotates 180 degrees at low speed to drop the water and discharge it to the bottom. The lower touch bar limit 59 sends a signal to the controller 120.

When the above process is completed, the air purge solenoid valve 68 is closed, and the reduction gear motor 51 is rotated by 180 degrees. When the upper touch bar limit 60 receives a signal, the low reduction gear motor 51 stops and the driving compound The bath 30 is in a horizontal standby position.

The dehydrated ash is stored in the dehydration storage hopper 71, and when the dehydration storage hopper 71 level meter 78 detects an upper value and signals the control unit 120, the dehydration storage vehicle waits for the dehydration material. The rotary discharge valve 79 of the storage hopper 71 is opened and continuously discharged to the pure water discharge hopper 81. When the dehydrated water falls to the front end of the screen body 101, the dehydrated water is the screen body. The portion 101 passes through the electromagnetic screens 102 and 103 and falls into the pure water discharge hopper 81, and iron is attached to the screen due to the magnetic force on the electromagnetic screens 101 and 103 while the resin passes through the screen.

The work time is charged 30 seconds, and when 30 seconds is completed, the forward and backward electromagnetic valve 99 of the pneumatic cylinder 98 is operated to move the pneumatic cylinder 98 forward, so that the primary electromagnetic screen 103 collects primary iron.

As the air purge solenoid 77 'is closed, the solenoid 99 of the pneumatic cylinder 98 is operated to reverse the pneumatic cylinder 98, and the moving wheel of the reversed screen body 101 is reverse limit 100'. When the signal is transmitted to the control unit 120 in contact with and the iron is collected in the secondary iron collection storage hopper 82 by repeating the same operation as the forward touch limit (100).

When the rotary discharge valve 79 of the dehydration storage hopper 71 receives a closing signal from the control unit 120, all the operations are temporarily stopped, and the lower level of the primary reinforcement storage hopper 8 is detected to control the control unit. The repetitive work continues to be operated until it is transmitted to 120, and when the lower level of the primary reclaim storage hopper 8 is detected and signaled to the controller 120, all the work is finished.

By dehydrating the moisture contained in the slag produced during the re-watering process of slag, the water is completely collected to prevent the environmental pollution caused by the large amount of waste water flowing into the drainage channel, and also to separate and discharge the fine iron contained in the dehydrated water completely. Therefore, it is effective in supplying high-quality water material by removing the satisfactory and defective products early in the post process.
