Abstract

(57) [Abstract] [PROBLEMS] To provide a scum removing device that ensures reliable and smooth floating return of a weir member. SOLUTION: A fixed trough that is a gutter shape with an open upper part and one side of which is the scum inflow side where the front side is set lower than the water surface and is fixedly installed in the sedimentation pond. Scum removal provided with a weir member mounted on the front side of the trough via a rubber plate so as to be movable forward and downward, means for periodically pushing down the weir member, and means for lifting and returning the weir member. In the apparatus, a balancer is provided as the means for lifting and returning.

Description

[Detailed description of the device]   〔Technical field〕   This invention relates to a scum removing device.   [Background of technology]   The Applicant is able to effectively remove the scum accumulated on the water surface of the sedimentation pond with an inexpensive one. The scum removing device designed to do so was previously proposed. The device has an open top. It has a trough-shaped trough, which is fixedly installed in the sedimentation pond. Front of trough , A hollow float is attached via an elastically deformable rubber plate so that it can move up and down. Have been. Since the float usually shows a part above the water surface, the float above the water surface Although the cam is blocked, it is pushed down below the surface of the water by the pushing-down means. The scum on the surface of the water flows into the trough.   By the way, since the weir member of the device is under water pressure when it floats, Initial pressing force is required, but if the weir member sinks to some extent, water pressure will not be applied too much. As the water containing scum passes above the dam member, Receive.   [Problems to be solved by the device]   Therefore, a corresponding force is required to return the weir member to the floating state. , Conventionally, by making the float hollow, it is possible to use the buoyancy to restore it. As a result, the weir member may not be able to be returned reliably and smoothly, which may cause malfunction. There was a risk of inviting me.   In order to solve the above-mentioned problems, the present invention ensures a smooth and smooth return of the dam member to its floating state. It is an object of the present invention to provide a scum removing device configured as described above.   [Means for solving the problem]   In order to achieve the above-mentioned object, the present invention has a gutter shape with an open top. The front side, which is one side, is set as a scum inflow side that is set lower than the water surface and is fixed inside the sedimentation pond. Fixed trough that is fixedly installed and the front side of this trough with a rubber plate A weir member that is mounted in such a way that it can project vertically and is vertically movable, and the weir member is pushed down periodically. To a scum removing device provided with a peeling means and a means for lifting and returning the dam member. A balancer is provided as a means for lifting and returning. It   〔Example〕   Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.   FIG. 1 shows an embodiment of this invention. This settling pond is lower than the water level 1. Equipped with an integrally fixed trough 3, and a scout is provided through an outflow pipe 2 communicating with the trough 3. Water is flowing out.   Another trough 4 is fixedly installed on the front surface of the trough 3. This trough 4 communicates with the trough 3, and the rear wall is higher than the water surface 1. However, the front wall is lower than the water surface 1 and is on the scum inflow side.   On the front side of the trough 4, there is a hollow flap through a rubber plate 5 which is slanted upward in the forward direction. A funnel (dam member) 6 is attached. This float 6 has a side seal 1 on the side surface. It is vertically movable while being sealed by 4, and its upper end is less than the water surface 1 when floating. It sticks out and is pushed down, so it sinks under a certain amount of water. Water by sinking While the scum on surface 1 flows into the trough 4 with some water, it floats and scatters. The inflow of mud water is blocked.   7 is a cylinder for pushing down the float 6, which is supported by a fulcrum 11. The upper arm 9 and the vertical push-down rod 13 so as to push down from above. It has become. A rod 12 extends horizontally from the arm 9, and a bar is provided at the rear end of the rod 12. The lancer 8 is attached.   Incidentally, 10 is an auxiliary float.   The float 6 pushed down by the cylinder 7 has a small water pressure and above it. It will be pushed down by the scum water flowing through, so even if you try to recover It may not be easy, but by installing the balancer 8 as described above, As a result, the float 6 can be returned to the floating state very reliably and smoothly.   [Effect of device]   Since the present invention is constructed as described above, is it possible to ensure that the weir member always returns to the floating position? Will be smooth.
