DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0025] Example:

[0026] like Figures 1 to 4 As shown, an oil-water separation device for extracting liquid includes a separation chamber A1, a separation chamber B2 and a foaming component, wherein the water inlet of the separation chamber A1 is connected to the connecting pipe A3, the water outlet of the separation chamber A1 is connected to the connecting pipe B4, the water outlet of the connecting pipe B4 is connected to the water inlet of the separation chamber B2, the foaming component is connected to the separation chamber A1, a water outlet pipe A11 is provided on the separation chamber A1, and a water outlet pipe B21 is provided on the separation chamber B2.

[0027] The bubbler assembly includes an air pump 5 and a bubbler 6, wherein the air pump 5 is connected to the bubbler 6 through a vent pipe 51, and the bubbler 6 is arranged at the bottom of the separation chamber A1. The bubbler 6 generates a large number of tiny bubbles that float upward, and during the bubbles floating upward, the oil in the water body rises to the water surface.

[0028] The bubbler 6 includes a main body 61, a partition 62 and a top plate 63. A cavity 64 is set in the main body 61, and the partition 62 is set in the cavity 64. The top plate 63 is connected to the top of the main body 61. The ventilation pipe 51 extends into the bottom of the cavity 64 and is connected. A plurality of through holes A52 are set on the ventilation pipe 51 to discharge the air of the air pump 5.

[0029] A plurality of through holes B65 are arranged on the partition 62, through which the bubbler 6 generates tiny bubbles. A through hole C66 is arranged on the top plate 63, and the diameter of the through hole C66 is larger than that of the through hole B65, so as to facilitate the release of tiny bubbles. A water inlet 67 is arranged on the side surface between the partition 62 and the top plate 63 of the main body 61, so as to facilitate the water body to enter the cavity 64 from the water inlet 67, so as to make the water flow there rise.

[0030] The separation chamber A1 is in a hollow cylindrical shape, and the connecting pipe A3 and the connecting pipe B4 are vertically distributed. Both the connecting pipe A3 and the connecting pipe B4 are tangent to the separation chamber A1 so that water forms a vortex in the separation chamber A1.

[0031] The separation bin B2 is hollow cylindrical, and the outlet height of the outlet pipe B21 is lower than that of the outlet pipe A11, so that the foamy oil-containing floating objects can flow out from the outlet pipe A11 after accumulating to a certain height, thereby reducing the amount of water flowing out of the outlet pipe A11.

[0032] The height of the water outlet of the connecting pipe A3 is slightly lower than that of the water inlet of the water outlet pipe A11. After the vortex is formed, the water surface in the middle of the vortex is lower than that at the edge, so that the oily floating objects gather in the middle and flow out from the water outlet pipe A11.

[0033] The height of the water inlet of the water outlet pipe B21 is greater than the height of the water outlet of the connecting pipe B4, so as to facilitate the outflow of oil-free water.

[0034] The outlet of the water outlet pipe A11 is located at the center of the separation bin A1, which is convenient for the water with oil to flow out after the vortex is formed. The water outlet pipe A11 can be connected to an oil collection device, and whether to reuse it can be determined according to actual production conditions.

[0035] The outlet of the water outlet pipe B21 is located at the center of the separation chamber B2 and below the water surface. The connecting pipe B4 can be arranged parallel to the diameter direction of the separation chamber B2 to avoid the formation of a vortex. Even if a small amount of oil floats on the water surface in the separation chamber B2, it will not flow out with the water outlet pipe B21.

[0036] When the device is used, the extracted water enters the separation chamber A1 through the connecting pipe A3, and enters the separation chamber B2 through the connecting pipe B4. Under the action of the bubbling component, the oil in the water in the separation chamber A1 floats up with the bubbles, and because a vortex is formed in the separation chamber A1, the oil floating on the surface of the water gathers at the center of the upper surface of the water in the separation chamber A1, and flows out through the outlet pipe A11. After the water enters the separation chamber B2, the water without oil flows out through the outlet pipe B21, which is convenient for reuse.
