Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a scum removal device.

[0002]

[Prior art]

 The scum removal device configured in the sedimentation pond consists of multiple (4) sprocket shafts that are axially oriented in the width direction of the pond, and two sprockets installed around each shaft. And two chains, left and right, which are endlessly hung through these sprockets. The device is driven by using some or all of the flights attached to the chain to attract and remove scum on the water surface. As one of the scum removing devices, a trough, a guide support sheet, a dam member, and a transmission mechanism are provided. The trough is a gutter-shaped long trough with an open upper part and a part of the front part of the square cross-section, and is fixed in the pond so that its longitudinal direction is oriented in the width direction of the pond. The dam member is supported by the rotary shaft at both left and right ends of the trough and is rotated with the movement of the interlocking arm at the end. Like the trough, the guide support sheet is a long strip and is made of rubber, and is attached to the front side of the trough in an overhanging manner so that it can be bent up and down by elastic deformation. The weir member is a long hollow member having a substantially triangular shape, and is attached to the front side of the guide support sheet in an overhanging manner, and is supported by the sheet so as to move up and down with the water surface as a boundary. A transmission mechanism swings the dam member up and down. The transmission mechanism is configured to convert the reciprocating motion by using the force of the flight that circulates in the sedimentation tank to move the dam member up and down.

[Problems to be solved by the device]

 By the way, the conventional scum removal device has a one-story structure. For example, if the river rises due to flooding and the water level in the sedimentation basin rises, a large amount of water flows into the trough, and this type of scrubbing is usually connected. In the scum removal device, there was a risk that the water level in the trough would rise and the trough would become full and flow backward. This invention has been made to eliminate these disadvantages.

[0004]

[Means to solve the problem]

 In order to solve the above-mentioned problem, in the device according to claim 1, the first scum inflow part having a dam member capable of moving the scum on the water surface together with water and moving up and down is constructed as an upper floor. On the other hand, on the lower floor, a scum from the first scum inflow part and a second scum inflow part into which water flows are configured, and by these, a trough having an upper and lower two-story structure is configured, and between the upper and lower parts, A valve capable of communicating the first and second scum inflow portions is provided, and the weir member can be linked to the valve.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 shows an embodiment of this invention. The trough 60 has a two-story structure of an upper floor 61 and a lower floor 62, and a valve 70 that can be opened / closed by a hinge 64 is provided at an outlet 63 formed in a bottom wall 61a of the upper floor so that the trough 60 flows into the lower floor portion by opening to the outside. You may be guided. In this case, the hinge 64 is made to interlock with a lever 66 provided at the end of the shaft 65, and the return is made by a weight 67. In this case as well, the water level tracking type weir member without the transmission mechanism or the copying member is similarly configured. However, when the transmission mechanism or the copying member is configured, the operation of the weir member 68 is performed as shown by the phantom line. The valve 70 may be configured to be transmitted and received by the rod 69 to open and close the valve 70.

[Effect of the invention]

 As described above, this invention has the two-story structure of the upper floor and the lower floor, and the valve is formed between them so that the weir member is interlocked with the valve. Came to
