The present invention relates to a chain-light type sludge and a scum removing device. A U-shaped scuff with a trackless chain guide plate and a chain light guide sprocket are installed at the front of the collecting trough of the sedimentation basin. In order to remove sludge and scum in sedimentation basin while moving along guide sprockets, tail sprockets and corner sprockets, the chain tracks are constructed by elevating the return tracks, scum truffs and chain guides by means of elevators. It is configured to be submerged deeply in the water so that the chainlight can be used as it is without difficulty even in the freezing ice machine.

A large amount of scum occurs on the surface of the initial and final settlers of sewage and wastewater treatment plants, and the sedimentation basin of some waterworks, which is not only visually unpleasant but also adversely affects water quality. It should be.

Conventional scum eliminators have been used such as pipe skimmers, helical skimmers, and flimtic skimmers, but pipe skimmers have difficulty in effectively removing scum from the sedimentation surface due to partial scum removal. The scum removal efficiency is good, but the installation cost is high, and the U-shaped scaffold with chain track guide plate and the chain light guide sprocket are installed at the front of the catchment trough of the sedimentation basin. It has been suggested in the Japanese Utility Model Publication (Publication No. 1982-95292) to move along guide sprockets, tail sprockets and corner sprockets to remove sludge and scum in sedimentation basin. The present invention has been developed because of the drawbacks that cannot be used. If imperfections of the compartment after removal device and the chain catching surface gyeolbinggi of winter by freezing operation while submerged in the water, the light will be described in detail on the basis of the accompanying drawings, it will Invar devised so that is difficult to remove the sludge as follows.

The driving mechanism (1) of the chain-flight type sludge collector is installed on the upper surface of the sedimentation basin slab (a), and the head sprocket (2), guide sprocket (3), tail sprocket (4) and corner sprocket (5) installed in the sedimentation basin are rotated. The return track 8 and the U-shaped scuff truff (7) are configured to pass through the U-shaped scuff trough 9 while being guided to the return track 8 by the backlight 7 assembled in the track 6. It is configured to elevate 9) to be submerged deeply in the water of the sedimentation basin, but the return track (8) is fixed to the slide bracket (10) to be elevated by the return track elevator (11) and the U-shaped scuff trough (9) the slide bracket Fixed to (12) to be elevated together with the guide sprocket (3) by the trough elevator (13) and the slide brackets (10) and (12) of the guide flanges (10a) and (12a) installed perpendicular to the settling wall surface Configure the lifting along the guide groove, and the sludge hopper (C) side You sprocket (5) was preceded by the warm water of the underwater gyeolbinggi by installing an air supply pipe (14) flows into the head-side sprocket surface.

In the figure, 1a is a drive chain, (b) is the bottom of the sedimentation basin, (d) is scum, and (b) is sludge.

The present invention is such that the track chain 6, which is engaged to the head sprocket 2 by the operation of the drive device 1 as shown in FIG. 1, the guide sprocket 3, the tail sprocket 4 and the corner sprocket 5 Move the side light (7) to collect the sludge (bar) of the bottom of the sedimentation basin (b) into the sludge hopper (c) to remove and remove the sludge (bar) to the U-shaped scuff (9) By collecting the scum (la) floating on the surface of the sedimentation basin and put it in the scum trough (9) to remove the sludge (bar) accumulated on the bottom of the sedimentation basin (b) and scum (la) floating on the surface of the sedimentation basin together. As is well known, but the present invention can raise and lower the return track (8) and the U-shaped scuff (9) and the guide sprocket (3) with the slide brackets (10) and (12), especially in the winter ice machine Return track (8), scuff (9) and guide sprocket (3) deep in water (approx. 1) m) The sludge removal device of the existing facility is installed in winter by moving the endless track chain (6) and the flight (7) which move while passing through the return track (8) and the scuff (9). It can be used as it is, and in the beginning of winter freezing, air is supplied from the air supply pipe 14 installed deep in the water at the head sprocket 3 position to create air bubbles in the water around the head sprocket 2, thereby freezing the water surface by the flow of water. The state can be prevented.

The present invention can be easily collected and removed together with the scum of the sedimentation surface and the sludge in the water in the sludge collecting device, and even if the water freezes, it is possible to use it by simple operation without disassembling or assembling the machine. There is an advantage to use.
