[Purpose of invention]

[Technical Field to which the Invention belongs and Prior Art in the Field]

The present invention cleans the water treatment process by eliminating the unclean impression of the water purification plant due to scum (SCUM: all foreign substances injured on the water surface during the water treatment process) during the water treatment process, and clean the existing water The purpose is to improve the inappropriate method due to the large amount of manpower and loss when applying the removal method.

The present invention relates to a system for removing scum generated during a water treatment process, which is a kind of water treatment equipment, and has been conventionally removed using a pipe skimmer, helical skimmer, scum suction pump, and direct gardening, and takes much manpower consumption and quantity loss. Had to. By not removing the scum generated in a timely manner, it not only impairs the beauty of the water purification plant and causes unclean impressions to visitors, but also the operational problems caused by scum (loss of power and electricity costs due to the increase of backwashing time due to the reduction of filter filtration duration). There are problems with labor expenses for wasting.

[Technical problem to be achieved]

The material handled in the present invention is a scum, which is the surface of the scum's surface, and is easily destroyed when the scum is impacted, dissolved in water, resuspended, and passed through without being caught in a fine wire mesh. There is a technical problem that needs to be eliminated. Thus to solve the above problem

-Scum stopper that blocks floating scum on the surface of the water

-A device to transport scum collected by scum collection plate to scum tank

-Device to discharge scum collected in scum tank

-It is necessary to configure an automatic control system that automatically operates the above operations. The description of each operation is as follows.

[Description of operation by drawing]

First

As the system configuration diagram of the present invention, the operation of the scum removing device is sequentially performed according to the command of the automatic control system (PLC), and when the scum collecting plate moves downward at the starting point of the scum removing operation, it stops at 5 cm below the water surface. After the scum is drawn to the inside of the scum tank by driving, the scum collecting plate moves upward without touching the scum at the time of reverse movement, and the scum discharge pump operates to discharge the scum in the scum tank at the same time. The car backing up will return to the starting position and complete the 1st scum removal cycle.

2nd view (front view)

1) In order to prevent the flow of scum, the scum stopper 16 is manufactured in a plate shape and installed across the sedimentation basin, and a stopper reinforcement stand 17 for strength reinforcement is installed. The scum stopper 16 comes out 10 cm above the water surface and the rest is submerged in water to prevent floating of the floating material as well as to prevent the scum generated in the flocculant from flowing to the sedimentation basin. It helps to be collected.

2) A driving rail frame 24 and a frame stiffening plate 4 are installed on the side of the scum stopper 16 and the driving rail frame 24 is connected to the driving frame support 9. And the driving frame support 9 is connected to the traveling frame support plate 25 and the traveling frame support plate 25 is fixed to the concrete structure.

3) The driving car 5 operates the driving motor 10 as a driving device to rotate the driving gear 1 so that the upper driving roller 3 and the lower driving roller 13 are driven along the driving path of the rack bar 2. With forward and backward movements.

4) When the Shanghai-dong motor 22 operates to transfer power to the vertical drive shaft 14 by chain power transmission, the Shanghai-dong drive gear 7 attached to the vertical drive shaft 14 rotates and the scum collector plate Shanghai-dong rack The kva 6 performs the shanghai dong so that the scum collector 19 is finally made the shanghai dong. At this time, the bushing bearing 8 serves to hold the moving shaft and to reduce friction.

5) The scum that rises from the sedimentation basin after passing the scum stopper 16 is collected by the sludge collector scum guide 27 and is pushed into the scum stopper 16.

2nd view (top view), 4th view (side view)

1) When removing the scum, all the movements are operated in the input sequence built into the PLC inside the control box.

2) When the collection plate holder 18 is moved upward based on the scum tank 21 to remove the scum and at the same time the vehicle 5 moves backward, it moves to the starting point for the scum removal operation.

3) The reverse of the vehicle 5 is stopped by the sensor at the starting point, and the movement of the vehicle 5 is performed in the state in which the scum collecting plate 19 is locked to 5 cm below the water surface by the driving of the shanghai-dong motor 22. Scum begins to collect.

4) As the collected scum passes through the scum guide plate 26, water is removed and collected into the scum only scum tank 21.

5) The scum collecting plate 19 is cleaned by the scum removing plate 20 while being lifted up by the drive of the Shanghai copper motor 22.

6) The scum tank level controller 23 is installed to adjust the scum to the level of water well introduced into the scum tank 21 according to the sedimentation basin level change.

7) The scum discharge pump 29 operates to discharge the scum in the scum tank 21 at the same time as the traveling vehicle 5 moves backward to the start point of the scum removal operation.

8) The scum that rises from the settling basin after passing the scum stopper 16 is stopped by the sludge collector scum guide 27, and the sludge collector is advanced to push the scum over the scum stopper 16. At this time, by operating the scum stopper winch 30 to move the scum stopper 16 below the water surface so that the movement of the scum is desired.

9) When the position of the sludge collector scum guide (27) pushing the scum is at the scum stopper (16), it stops moving forward and moves the scum stopper (16) upward to prevent downstream movement of the scum and at the same time the sludge collector scum guide ( 27) returns to the role of preventing the flow of scum generated after the sedimentation basin.

The scum is removed in the sequential order as above, and the operation frequency and speed can be adjusted according to the scum's generation amount, and it is possible to operate automatically for 24 hours, greatly reducing manpower and water loss, and excellent in maintaining clean water at the purification plant.
