Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, and in particular relates to a pressurized oil-water separator. Background Art

[0002] The oil-water separator is used to separate oil and water. Due to its high oil content and the impurities generated after use, its filtration resistance increases and its filtration efficiency decreases. On the other hand, the filter element of the oil-water separator needs to be replaced regularly after long-term use. For the common integral structure, it is not easy to replace, and some parts that can still be used will be replaced together with the overall replacement, which will increase the cost of using the oil-water separator. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a pressurized oil-water separator.

[0004] The technical solution provided by the utility model is as follows:

[0006] A cylinder, wherein an impurity filtering area and a moisture filtering area are arranged in the cylinder, a rotating shaft is arranged in the impurity filtering area, and blades are arranged on the rotating shaft;

[0007] A fixed middle partition is provided, wherein the middle partition separates the impurity filtering area from the moisture filtering area, and a gap is provided between the middle partition and the inner wall of the cylinder.

[0008] Based on the above technical solution, the blades are driven by the rotating shaft to increase the pressure on the oil and water to promote their flow, enhance their power to pass through the filter structure, and improve the filtering efficiency.

[0009] Specifically, the impurity filtering area includes a tubular impurity filtering net, one end opening of the impurity filtering net is fixed on a bottom wall of one side of the cylinder, and the other end opening of the impurity filtering net is tightly fitted with the middle partition or crimped on the middle partition.

[0010] Specifically, the rotating shaft is arranged along the axial direction of the impurity filtering screen, and the blades extend in a direction away from the axis.

[0011] Based on the above technical solution, the blades can press the oil and water outwards during the rotation of the rotating shaft, apply pressure to the oil and water, and promote their flow.

[0012] Specific:

[0013] The cylinder is a cylindrical structure;

[0014] The middle partition is a disc structure with a diameter smaller than that of the cylinder, and is fixedly mounted on the outer circumference to the inner wall of the cylinder through a plurality of evenly arranged connection structures.

[0015] Further:

[0016] A circle of limiting ring is arranged on the outer periphery of the middle partition plate, and the bottom outer periphery of the impurity filter screen is closely fitted with the inner wall of the limiting ring.

[0017] Based on the above technical solution, the bottom of the impurity filter can be limited.

[0018] Specifically, a motor is arranged on the bottom wall fixedly connected to the impurity filter screen, and an output shaft of the motor is fixedly connected to the rotating shaft.

[0019] Specifically, a plurality of liquid inlets are arranged on the bottom wall of the cylinder, and the liquid inlets are arranged around the circumference of the motor.

[0020] Specifically, the water filter area includes a tubular water filter screen, one end of which is opened and fixedly connected to the middle partition, and the other end of which is opened and fixedly connected to the bottom wall of the other side of the cylinder.

[0021] Specifically, an oil outlet is provided in the middle of the bottom wall fixedly connected to the water filter.

[0022] Furthermore, the cylinder is formed by two parts being fixedly connected, for example, they can be threadedly connected at the ends.

[0023] Based on the above technical solution, the impurity filter area and the water filter area can be easily disassembled. After disassembly, the impurity filter screen exposes the lower opening, and the inner wall of the impurity filter screen can be easily cleaned of impurities. In addition, the outer wall of the water filter screen can also be cleaned of water.

[0024] The impurity filter can adopt existing technology, for example, a metal filter, or existing filter materials such as high-density filter paper supported by a metal frame.

[0025] The water filter can adopt existing technology, for example: oleophilic and hydrophobic water separation material supported by metal or plastic framework.

[0026] The beneficial effects of the utility model are as follows:

[0027] 1) The oil and water can be pressurized to improve the separation efficiency.

[0028] 2) The device can be disassembled to remove impurities from the inner wall of the impurity filter and the outer wall of the water filter. BRIEF DESCRIPTION OF THE DRAWINGS
