Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil-water separation technology, in particular to an oil-water separator. Background Art
[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] Oil-water separators are important basic separation devices, widely used in the production and life processes of petroleum, chemical industry, medicine, etc., such as the recovery and separation of oil spills on the water surface, the oil-water separation of crude oil in modern oil production, the filtration of engine fuel, and the separation of organic matter and water in the production of chemical drugs. At present, common oil-water separators mainly use the difference in oil and water density to separate oil and water through gravity, centrifugal force, etc. The separators themselves generally have defects such as high energy consumption, large size, high weight, and high cost. Therefore, the research on energy-saving, environmentally friendly, efficient, low-cost and continuously operating oil-water separators is of great value and significance.
[0004] In recent years, with the emergence of hydrophobic materials, the corresponding separation membranes have gradually matured, making it possible to design and manufacture simpler oil-water separation devices, and related research has also achieved initial results. However, most of the existing oil-water separation equipment is a bottom-feed, top-discharge method. When separating oil and water, the last batch of materials cannot be fully utilized, especially not suitable for intermittent production, resulting in material waste. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the embodiments of the utility model is to provide an oil-water separator to solve the problem that the existing oil-water separation equipment cannot fully utilize the last batch of materials.

[0012] Since the oil phase is lighter than the water phase, the oil phase floats on the water phase, and the excess water is discharged through the drain port to maintain the normal operation of the oil-water separator. Since the drain port is at the bottom of the filter cylinder, the equipment can fully utilize the last batch of materials to prevent material waste.
[0013] In some embodiments, the filter element is a perforated filter element, the middle of the filter element is a hollow channel, and the filter element is coated with an oleophilic and hydrophobic membrane. The oil phase passes through the oleophilic and hydrophobic membrane through the small holes into the hollow channel of the filter element and is discharged through the oil discharge port.
[0014] In some embodiments, both the feed port and the drain port are provided with valves.
[0015] In some embodiments, the oil discharge port is provided with a valve, and the oil discharge port is connected to the oil storage tank through a pipeline.
[0016] In some embodiments, an oil storage chamber is provided below the filter cylinder for temporarily storing the oil phase. The oil storage chamber is disposed between the oil discharge port and the filter element, and the oil storage chamber is communicated with the oil discharge port and the filter element.
[0017] In some embodiments, a lower end seal is provided at the lower end of the filter cylinder so that the oil storage chamber and the filter cylinder are not connected to each other.
[0018] In some embodiments, a cover plate is disposed at the upper end of the filter cylinder, and a slot cooperating with the filter element is disposed on the cover plate for clamping the filter element.
[0019] In some embodiments, the lower head is provided with a threaded hole, and the filter element is connected to the lower head via threads.
[0020] In some embodiments, the filter element is connected to the oil storage chamber through a threaded hole.
[0021] In some embodiments, a plurality of filter elements are disposed in the filter cartridge.

[0024] 2. The device of the utility model is particularly suitable for intermittent production conditions. When the material is less, all the materials can be filtered, separated and utilized, and can adapt to the conditions of intermittent production when the material is less.
[0025] 3. The utility model also has the advantages of simple structure, easy use, small footprint and low energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0031] As introduced in the background technology, the oil-water separation equipment in the prior art has a complex structure and cannot fully utilize the last batch of materials, and is particularly unsuitable for intermittent production conditions. In order to solve the above technical problems, the utility model proposes an oil-water separator.
[0032] like Figure 1 As shown, some embodiments of the utility model record an oil-water separator, including: a filter cylinder 6, a filter element 7, a feed port 2, a drain port 3 and an oil drain port 5;
[0033] The feed port 2 is located at the upper part of the filter cylinder 6, and the drain port 3 is arranged at the lower part of the filter cylinder 6; the feed port 2, the filter cylinder 6 and the drain port 3 are connected; a plurality of filter elements 7 are arranged in the filter cylinder 6, the filter element 7 is a filter element with holes, the middle of the filter element 7 is a hollow channel, the outer surface of the filter element 7 is wrapped with an oleophilic and hydrophobic membrane, and the hollow channel inside the filter element 7 is connected with the oil drain port 5. The oil-water mixture enters the filter cylinder 6 through the feed port 2, the oil phase enters the filter element 7 through the oleophilic and hydrophobic membrane and the small holes, the water phase is blocked outside the filter element 7, and the oil phase is collected in the hollow channel and flows into the lower oil drain port 5 for discharge, thereby achieving oil-water separation.
[0034] In some embodiments, the feed port 2, the drain port 3 and the oil drain port 5 are all provided with valves, the feed port 2 is connected to the previous process through a pipeline, the oil drain port 5 is connected to the oil storage tank or the next process through a pipeline, and the drain port 3 is also connected to the pipeline to discharge water.
[0035] In some embodiments, a lower head 4 is provided on the bottom surface of the filter cylinder 6 to separate the oil storage chamber 8 from the filter cylinder 6. The oil storage chamber 8 is provided below the lower head 4 of the filter cylinder 6 and between the oil drain port 5 and the lower head 4 for temporarily storing the oil phase.
[0036] In some embodiments, the lower head 4 and the filter element 7 are sealed and connected via a thread 9. The lower head 4 is provided with a threaded hole, and the lower end of the filter element 7 is also provided with an external thread. The filter element 7 is connected to the threaded hole of the lower head 4 via the external thread, and the oil phase entering the hollow channel of the filter element 7 is collected into the oil storage chamber 8 through the channel of the threaded hole.
[0037] In some embodiments, a cover plate 1 is provided at the upper end of the filter cylinder 6, and a slot 10 is provided on the cover plate 1 according to the position of the filter element 7.

[0038] During use, when there is less material, open the valve of the feed port 2 and close the valve of the drain port 3. The oil-water mixture enters the filter cylinder 6 through the feed port 2, and the oil phase enters the filter element 7 through the lipophilic and hydrophobic membrane and the small holes. The water phase is blocked on the outside of the filter element 7, and the oil phase gathers in the hollow channel and flows into the oil drain port 5 at the lower part for discharge, thereby achieving oil-water separation. When the oil phase in the filter cylinder 6 has basically entered the filter element 7, open the valve of the drain port 3 to discharge the remaining water phase, and open the valve of the oil drain port 5 to discharge the oil phase.
[0039] When the oil-water mixture is continuously introduced through the feed port 2, the valve of the feed port 2 is opened, and the valve of the drain port 3 is closed. After the material in the filter cylinder 6 reaches a certain height, the valve of the drain port 3 is opened to make the water flow rate of the water inlet and the water outlet equal, and the oil phase enters the filter element 7 through the oleophilic and hydrophobic membrane and the small holes to achieve oil-water separation.
