The oil inlet pipeline penetrates into the tank body from the upper side of the side face of the tank body and is positioned in the center of the tank body. A foam breaker is arranged above the oil inlet pipeline in the tank body. Three layers of support rods are sequentially arranged under the bent pipe section of the oil inlet pipeline, and the first-stage baffling conical thin cover, the second-stage baffling conical thin cover and the third-stage baffling conical thin cover are fixedly connected with the inner wall of the tank body through the three layers of support rods respectively. The four-level baffling conical thin cover is obliquely arranged below the three-level baffling conical thin cover, the four-level baffling conical thin cover is obliquely welded in the tank body, and a round hole is formed in the tank body corresponding to the bottom end of the four-level baffling conical thin cover, so that the fluid can be conveniently and rapidly collected. The round hole is communicated with a water content measuring pipeline which is externally connected with a water content measuring instrument. The side wall of the tank body below the four-level baffling conical thin cover is provided with a ball float valve, and the bottom of the tank body is provided with an outlet pipeline.
The top points of the first-stage baffling conical thin cover and the third-stage baffling conical thin cover are placed downwards towards the upper round surface and are used for flowing down of fluid through the edge of the big circle of the cone. The second-stage baffling conical thin cover and the fourth-stage baffling conical thin cover are in the shape of round tables, the diameter of an upper round table surface of the second-stage baffling conical thin cover is larger than that of a lower round table surface, the diameter of an upper round table surface of the fourth-stage baffling conical thin cover is smaller than that of the lower round table surface, round holes are formed in the centers of the round tables, and fluid flows through the middle round holes.
