Description

Float Removal Device {REMOVING DEVICE FOR REMOVING FLOATING MATTER}

The present invention relates to an apparatus for removing suspended solids, for example, oil spilled from the surface of the water, in particular oil which has become an emulsion with oil or water whose viscosity is greatly increased due to a drop in temperature.

Various types of oil removal devices, such as weirs, discs and brush skimmers, are used to separate and collect contaminants from the water surface. In general, these devices cannot be effectively used in the event of waves due to design problems in water and lack of safety. Often these devices collect a lot of water together at the same time, so that the float cannot be effectively collected in a concentrated form. In addition, existing techniques are not able to practically solve oils and oils of high viscosity that have become emulsions with water overall.

Since oil poses a serious danger due to water contamination, the problem of removing suspended solids, especially thin oils from the surface of the water, is very important. Such floats form a thin layer that contaminates the surface of the water and these contaminants do not mix with the underlying water and remain pure or form an emulsion with water. If a river, lake, or sea spills on these oils, these contaminants form a very thin and broad layer that does not mix with water in its initial state. But soon blue and wind cause the oil to form an emulsion with water and no longer remain liquid. This happens in wrecked tankers or in accidents during offshore oil extraction.

This same problem also arises from wastewater purification, especially from wastewater purification from industrialized areas. In this case the contaminants form an emulsified layer with the water but cover a relatively narrow area. In all such cases the fluid contaminants may or may not be liquid. This bottom layer is not mixed and contaminants form a thin layer on the surface of the bottom layer, which forms a relatively thick layer.

Therefore, it is difficult to separate the thin layer of contaminants from the thick layer formed below to recover the contaminants without forcing the transfer of the suspended matter into the hopper and increasing the thickness of the layer of this contaminant. Indeed, attempts have been made to remove contaminants with the aid of a pump having a suction fallopian tube floating on the surface of the contaminants. However, inhalation fallopian tubes cannot function normally because of contaminated surfaces of contaminated rivers, lakes, and seas caused by surges or winds. In particular, the contaminated oil layer, which has been emulsified with water, cannot be removed by conventional equipment such as disk skinners or brush skimmers.

The present invention overcomes the aforementioned difficulties in removing suspended matter from water.

The float removing apparatus of the present invention comprises a stator, a rotor rotationally supported by the stator, a screw means rotationally supported by the rotor, a hopper, a baffle means surrounding the hopper, and a conveying means.

A radially horizontally arranged screw means which is rotatably supported about its longitudinal axis on a rotor which is rotationally supported by the stator about its vertical axis draws oil in a broadly enclosed area into the baffle means. The screw means, which rotates about the stator while rotating about its longitudinal axis, also has a float to serve as a striking furnace to give stability in the event of a wave. This movement of the screw means forcibly transfers the oil, which has become emulsion with water and the oil which has increased in viscosity due to the drop in temperature, into the hopper. Preferably such screw means allows the driver to adjust the speed of movement on the ship. Increasing the rotational speed of the screw means may increase the flow rate of the float entering the baffle means.

The central hopper is surrounded by baffle means having an inlet for the suspended means to reach the hopper through which the conveyed float is introduced. The weir of the hopper prevents liquid of high specific gravity from entering the hopper.

The opening is located at the bottom of the baffle means below the water surface so that water is led out of the baffle means. In general, the baffle means retain oil and water therein, thereby stabilizing the movement of the float removal apparatus of the present invention in water. Such baffle means are very useful for providing additional stability to the float removal apparatus.

The transfer means is connected to the discharge channel of the stator for pumping and transporting the suspended matter from the discharge channel of the stator to an external storage tank and includes a pumping means and a transfer line.

The float removal device is applicable to any size in diameter. Relatively large devices are stable in the oceans with high waves and can effectively handle many floats.

Therefore, it is usually necessary to hydrodynamically increase the bed before releasing the contaminants. In particular, a baffle means having a circular shape on the water surface is used such that an inlet is provided in the circular circumferential wall for accumulating effects caused by obstacles, for example, to collect contaminants.

In this way contaminants can be removed by pumping or flowing over the weir into a hopper placed in the baffle means. When the water is covered with the contaminant the thickness of the layer of contaminant increases radially outward to the center of the rotor. So the contaminants are pumped through the outlet channel of the stator which is hollow in shape.

The process according to the present invention includes the process of pushing down the contaminants spreading on the water surface, accumulating the collected contaminants to increase the thickness of the contaminant layer, and recovering the thicker contaminant layer.

The screw means 3 are partially submerged in water when in use such that the longitudinal axis is approximately radially outward from the rotor 2 and approximately full length along the water surface to transport the float while sweeping the surface. In the rotor 2 it is rotationally supported about its longitudinal axis.

Thus, the screw means 3 together with the rotor 2 rotates about the stator 1 with respect to the vertical fixed axis 13 of the stator 1 (rotating direction B) and at the same time the rotor In (2), rotate about its longitudinal axis (rotational rotation direction A).

The bevel gear 41 and the bevel gear in order to rotate the screw means 3 about its longitudinal axis while the screw means 3 rotates around the stator 1 together with the rotor 2.

In the present invention thus configured, each of the three screw means 3 with the helical blade 34 fixed to the screw shaft 31 and the cylinder float 32 has a radius like a protruding nosepiece around the stator 1. In a direction isometric.

The drive motor 11 mounted on the motor platform 14 rotates the screw shaft 31 of the screw means 3 via the rotor 2 and the bevel gear unit 40. To adjust the buoyancy of the screw means 3 the float 32 can be filled with the required amount of fluid by the use of a stopper used to drain it.

The helical blade 33 on the surface of the screw shaft 31 allows the helical blade 33 on the surface of the screw shaft 31 to be easily transported in the liquid conveyed by the helical blade 34 on the surface of the cylinder float 32. The diameter of the helical blade 33 is made smaller than the diameter of the cylinder float 32.

The pitch 35 of the helical blade 33 on the surface of the screw shaft 31 is smaller than the pitch 36 of the helical blade 34 on the surface of the cylinder float 32 in order to thicken the surface layer of the float. The movement of the helical blade 34 of the screw means 3 causes the float swept by the cylinder float 32 to move towards the center of the stator 1.

As the pitch 36 of the helical blade 34 of the screw means 3 decreases towards the center of the stator 1, the layer of floating float of water becomes thicker.

In addition, the above-mentioned float removal apparatus provided with the screw means 3 can collect the emulsion formed from oil and water.

It can be used even when the oil temperature becomes high due to the temperature drop, and it can be used even when the seawater digging is high.
