Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically, to a fuel water separator filter. Background Technology

[0002] A fuel filter is a filter connected in series at the engine's fuel inlet to effectively separate water from the fuel. If the water content in the fuel exceeds the standard, it directly affects the performance of the power unit, leading to the following problems: engine surge, difficulty or failure to ignite, difficulty in engine control, and impaired engine operation; it causes poor engine idling speed, and if the engine cannot reach its rated power or speed, water can freeze, damaging the fuel injectors; water in the fuel dissolves in sulfides, forming acidic substances during fuel injection, increasing corrosion of parts, promoting microbial growth, and clogging the filter; the lubricity of the fuel is weakened, accelerating the wear of fuel system components, and in severe cases, even causing cylinder scoring.

[0003] Therefore, fuel water separators are needed to remove excess water and solid particulate impurities from fuel. Existing fuel water separators have a simple structure, mostly welded from stainless steel, resulting in poor structural integrity; they also lack adjustable filtration flow and rate; and the filter element replacement efficiency is low, requiring the fuel line to be shut off before replacement. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fuel water separator to solve one or more of the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fuel water separator includes a left filter and a right filter, which are connected by a conversion assembly. The conversion assembly connects the left filter or the right filter. Both the left filter and the right filter are equipped with a filter assembly that separates oil and water. Both the left filter and the right filter are equipped with a water level detector, a drain valve, and a differential pressure alarm.

[0007] Furthermore, the outer housing of the conversion assembly is connected to the left filter and the right filter simultaneously through flow channels on both sides. The conversion assembly is equipped with a rotor, which is rotatably connected to and fits against the housing. The surface of the rotor is provided with an interface corresponding to the flow channel.

[0008] Furthermore, a handle is provided on the top of the rotor, the handle is located outside the conversion assembly, and the handle drives the rotor to engage and connect with the left filter or the right filter.

[0009] Furthermore, the rotor rotates at least 90° to engage with flow channels on different sides, and both the ports of the flow channels and the interfaces of the rotor are provided with sealing couplings.

[0010] Furthermore, the filter assembly includes a water-distributing filter element, the surface of which is a superhydrophobic and oleophilic mesh structure. The water-distributing filter element is suspended and connected to the oil outlet pipe at the top. The bottom of the left filter or the right filter is a water storage area. The water level detector is installed in the water storage area. The drain valve is connected to the bottom of the water storage area. The water level detector is electrically connected to the drain valve.

[0011] Furthermore, the water separator is externally encased in a protective filter element, and the surface of the protective filter element is provided with a filter screen.

[0012] In summary, this utility model has the following beneficial effects: By designing a protective filter element and a water-separating filter element, solid impurities and water are filtered in stages, resulting in high-purity oil; water is separated from the fuel using superhydrophobic and oleophilic materials, dripping to the bottom by gravity, with automatic alarm and drainage triggered by the water level detector; internal differential pressure is monitored by a differential pressure alarm, facilitating timely filter element replacement; the left and right filter design allows for switching or adjusting the flow rate by rotating a handle, making operation more flexible and facilitating simultaneous filtration on one side and replacement of the filter element on the other, greatly improving filtration efficiency and extending the overall service life.

[0016] Example:

[0017] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0018] Fuel water separator, such as Figure 1 As shown, the main body consists of a single, integrally molded left filter 1, a conversion assembly 3, and a right filter 2. The left filter 1 and right filter 2 are connected via the intermediate conversion assembly 3. These three components can be considered as three separate housings, interconnected by a flow channel. Figure 2As shown, the conversion assembly 3 contains a rotatable rotor that docks with a base at the bottom. A handle 6 is located on the top of the assembly, outside the assembly 3. A seal is installed between the top of the handle and the housing of the conversion assembly 3 to ensure that the rotor's rotation does not compromise the overall sealing of the equipment. The rotor itself fits snugly against the inner wall of the conversion assembly 3's housing to prevent oil leakage. Openings are provided on the flow channels on both sides of the rotor. By rotating the rotor, these openings align with the flow channels on different sides, allowing connection to the left filter 1 or the right filter 2, thus completing the switching. The rotor also requires an external oil line to introduce unfiltered fuel. The rotor's rotation angle should be at least 90° so that accidental rotation will not directly affect the operation of a single filter. Sealing fittings are preferably installed at the ports of the flow channels and the rotor's interface to further prevent oil leakage.

[0019] like Figure 1 As shown, both the left filter 1 and the right filter 2 contain filter components that separate oil and water. A differential pressure alarm is located at the top, monitoring the differential pressure at the upper position. Once an alarm sounds, the filter component needs to be replaced. The filter component consists of two filter elements. The outer element is the protective filter element 8, which comprises a filter element frame and a filter screen. Made of 316L stainless steel, it separates solid impurities and features high mechanical strength, high-temperature corrosion resistance, good air permeability, and stable filtration performance. When the differential pressure alarm is triggered, the protective filter element 8 is replaced. Enclosed by the protective filter element 8 is the water separator filter element 7, made of a special superhydrophobic and oleophilic membrane material with a stainless steel mesh lining. The water separator filter element 7 is designed as a folded filter element with support. Fuel flows from the outside in. Water-containing fuel spreads across the coating surface, and the hydrophilic membrane causes oil molecules to exchange and permeate, moving in the direction of fuel flow. Water is repelled and aggregates with other free water, settling to the bottom of the filter under gravity to form a water storage area. This separation method is more direct, precise, and durable. The water separator element 7 is suspended and connected to the external outlet pipe, allowing the fuel to flow by overflow. A drain valve 5 is located at the bottom of the water storage area, and a water level detector 4 is installed inside. When the bottom water level reaches the water level detector 4, an alarm sounds, indicating the need for drainage. The linked drain valve 5 then automatically drains the fuel.

[0020] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
