Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a suspended matter recovery device.

[Conventional technology]

 For example, in urban rivers, a large amount of suspended solids such as dust flows, which adversely affects various areas, so countermeasures are desired.

[Problems to be solved by the device]

 Until now, floating matter was allowed to flow freely, so drinking water that uses river water was contaminated, and pollution was severe in the sea where the floating matter flowed.

 The present invention has been made to solve such a problem, and its problem is to be able to solve the water pollution of rivers by a simple device.

[Means for solving the problem]

 In order to solve the above problems, the present invention is an apparatus for collecting suspended matter on the water surface, which is installed in a place where there is a flow such as a river or the sea. A trough that is installed near the water surface so that it is low, a pole-shaped support member that supports the trough at one end of the trough so that the trough can swing, and can move up and down to follow the water surface, and the trough has an inlet. A control device that directs the water to the upstream side and avoids it from countering the flow of water depending on the flow load from the water, and the suspended matter and water that are connected to the trough and are introduced into the trough. Both of them are characterized in that they are equipped with a discharge means for extracting them to the outside and a suspension device for separating the suspended solids and water from the discharge means into a suspended solid and water, and a separation device for treating the suspended solids to recirculate the water to a river or the sea. And

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

 1 to 3 show an embodiment of the present invention. This embodiment is intended for a river, and 1 is a river, a water surface 2 is set in the river 1, and water flows as shown by an arrow X. Floating matter flows on the water surface 2 along with this flow of water, and this device collects these floating matter one after another.

 Reference numeral 3 is a trough, and the trough 3 is a trough shape elongated in one direction, and both ends in the longitudinal direction are closed by plates 4 and 5. At one end of the trough 3, a rotary pipe 6 that rises from the inside is provided, and the pipe 6 is fitted to the outer periphery of a pole (support member) 7 that is driven into the bottom of the river 1 and fixed. The trough 3 is swingable and can be raised and lowered so as to follow the water surface.

 The trough 3 is usually oriented in the longitudinal direction so as to be orthogonal to the water flow direction X. A control device 10 is provided to maintain this posture. The control device 10 includes a support base 11, a motor 12 provided on the support base 11, and a transmission 13.

By turning the motor 12, the trough 3 swings in the clockwise direction in FIG. 1 to take the orthogonal posture. This force is generated using the wire 16 connected from the first pulley 14 to the protrusion 17 on the outer circumference of the pipe 6 via the second pulley 15. At the front part of the trough 3, an inlet 18 is provided, and the trough 3 is installed so that the inlet 18 is slightly lower than the water surface 2. For example, in the case of flooding, when the load on the trough 3 becomes large due to the water flow, the load is applied to the wire 16, and the load causes the motor 12 to loosen the wire 16 and move to the phantom line in FIG. Thus, the longitudinal direction of the trough 3 is avoided so as to face the flow of the river 1.

When the flood ends, the motor 12 can be driven to return to the state shown by the solid line in FIG.

 One end of the trough 3 on the pole 7 side has an open bottom, and a pit 19 is provided below this portion. In this pit 19, a pump 20 which is a main part of the outlet means is provided, and the suspended matter and water in the trough 3 are sucked together by the pump 20. Float and water from pump 20 is directed to separator 22 through tube 21. This separating device 22 is composed of a plurality of rows of plates 23 for sending suspended matter and water in a meandering manner up and down, and a chemical treatment system 24 provided downstream thereof. The suspended matters 25 separated by this are returned to the treatment device, and the water is returned to the river 1 through the reflux pipe 26. 27 is a chemical inlet.

 The device for controlling the trough 3 is, as shown by the phantom line in FIG. 1, the pulleys 28, 28 installed one by one on the opposite shore to bypass the wire 29 over the river 1 and to bypass the trough 3. May be controlled. The motor 12 can use the above-mentioned thing.

 Further, as shown in the figure, the control device 30 provided on the other side of the river 1 can also be used for control.

 Further, as shown in FIG. 4, the rotary pipe 31 may be provided with rollers 32, 32, which may be moved up and down along the pole 33.

 Further, as shown in FIG. 5, in order to increase the stability of the trough 3, front and rear protruding receiving plates 34 ... Are arranged on the bottom surface of the trough 3, and floats 35, 35 are provided in front of and behind each of the receiving plates 34. It may be provided.

 6 to 8 show additional embodiments.

 This embodiment shows, for example, a method for recovering suspended matter such as dust (or crude oil) floating on the sea.

 That is, a large number of troughs 50 as in the above-mentioned embodiment are used, and these are arranged in an annular shape so that all the attraction ports 51 face inward and are connected to each other by a communication pipe 52. Before and after each trough 50, floats 54 using a bottom plate 53 are arranged. A pipe 55 is connected to some of the troughs 50.

 Crude oil 56 floats inside the trough 50, and these dusts 56 are drawn into the trough 50 through the attraction port 51 set below the water surface. The dust 56 guided into the trough 50 is guided to the pipe 55 by passing through another trough 50 or the like. The dust from the pipe 55 is introduced into the separation device 57 together with water. This separating device 57 is installed on the shore. In the separating device 57, dust and water are separated in the same manner as in the above-described embodiment, and the dust is passed to the next dust treating device as indicated by an arrow, and the water is also removed. Is configured to be returned to the sea through a return pipe 58.

 FIG. 9 shows another additional embodiment.

 This embodiment relates to an improvement of the one shown in FIG. 6, in which troughs 50 are arranged in an annular shape, and pipes 55 are connected to only three of these troughs 50. However, in this case, the suction force increases only in the trough 50 to which the pipe 55 is connected, and the suction force does not reach the other troughs 50. On the other hand, in this embodiment, an auxiliary pipe 61 is provided below the trough 60, and the auxiliary pipe 61 and the trough 60 are connected by a communication pipe 63 with a valve 62. The valve 62 can be operated by a wire 64, and the wire 64 is opened and closed sequentially in the circumferential direction viewed from above in FIG. Accordingly, when a certain wire 64 is pulled to open the valve 62, the suction force acting through the auxiliary pipe 61 extends into the corresponding trough 50 (for example, the one on the left side in the figure) and the dust inside the trough 50. And, the water is introduced into the auxiliary pipe 51. At this time, the other valve 62 is closed. Next, the valve 62 is closed (the valve 62 on the right end is also closed) and the valve 62 on the right side of the drawing is opened, so that the suction force acts on the trough 60 corresponding to this time. . At this time, the valves 62, 62 at the left end and the right end are closed. Further, the left two valves 62, 62 are closed and the rightmost valve 62 is opened. As a result, the suction force acts on the trough 60 at the right end. By doing so, there is no place where the suction force does not work, and the suction is made all over the circumference.

 FIG. 10 shows a combustion method of the crude oil described in the above embodiment when the crude oil is recovered.

 That is, a base plate 71 is provided on the twin-body type floating bodies 70, 70, and a pipe 72 is provided so as to penetrate the base plate 71. The pipe 72 projects upward and has an outlet 73 at its tip. From the blowout port 73, the recovered heavy oil is blown out through the pipe 72. The blown heavy oil is burned in the combustion chamber 74 surrounding the upper end portion of the pipe 72. Air is introduced into the combustion chamber 74 to promote combustion.

 Since the combustion is carried out in the floating of heavy oil, the base plate 71 is positioned above the water surface and the outer periphery is covered with a hermetic safety cover 75 in order to enhance safety.
