[Purpose of invention]

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

TECHNICAL FIELD OF THE INVENTION

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 suffers a lot of manpower consumption and quantity loss. I had to. The failure to remove the scum in a timely manner has not only damaged the aesthetics of the water purification plant and caused unclean impressions to visitors, but also the operational problems caused by scum (loss of power and power costs due to the increase in backwashing due to the reduction of filter filtration duration). There are problems such as labor cost for wasting.

[Technical task to achieve the invention]

The material covered in the present invention is a scum, which is the surface of the scum where the scum is generated and when it is impacted, the scum is destroyed, dissolved in water, resuspended, and passed through without being caught in a fine wire mesh. There is a technical problem that must be removed with caution. Thus to solve the above problem

-Scum stopper that blocks the floating scum on the surface of the water and the driving system of the scum collecting plate that collects the scum of the sleep across the scum stopper

-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.

[Brief Description of Drawings]

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

FIG. 2 (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 10cm above the water surface and the rest is submerged in water to induce floating, as well as preventing scum generated from the flocculant from flowing into the sedimentation basin and the scum is collected when the scum collecting plate 19 is moved. It helps.

2) A driving rail frame 24 and a frame stiffening plate 4 on which the traveling vehicle 5 can move are installed next to the scum stopper 16, and the driving rail frame 24 is mounted on the driving frame support 9. The running frame support 9 is connected to the driving frame support plate 25 and the traveling frame support plate 25 is fixed to the concrete structure.

3) The driving vehicle 5 operates the driving motor 10, which is 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 vertical movement motor 22 is operated to transmit power to the upper and lower drive shafts 14 by chain power transmission, the Shanghai-dong drive gears 7 attached to the vertical drive shafts 14 rotate and the scum collector plate Shanghai-dong racks The kva 6 performs the shanghai dong so that the scum collection plate 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 pushed into the scum stopper 16.

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

1) When removing scum, all the movements are operated in the input sequence built into the PLC inside the control box, and the start and end of each operation are configured to receive signals by the sensor and the limit S / W.

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 driving vehicle 5 is stopped by the sensor at the starting point, and according to the movement of the driving vehicle 5 with the scum collecting plate 19 locked to 5 cm below the water surface by the driving of the Shanghai-dong motor 22. Scum begins to gather.

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 driving of the Shanghai copper motor 22.

6) The scum tank water level adjuster 23 is installed to adjust the scum to the water level well flows into the scum tank 21 according to the change in the sedimentation basin level.

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 winding machine 30 to move the scum stopper 16 below the water surface to facilitate the movement of the scum.

9) When the position of the sludge collector scum guide 27 that pushed the scum comes to 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 of the water purification plant.
