[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an oil-water separator with a water level sensor. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts, and as people's living standards improve, their car consumption is increasing, and the market for automotive parts is growing larger. These include engine assemblies, filters, cylinders and components, oil seals, fuel pumps and injectors, fuel savers, valve tappets, fuel lines, connecting rod assemblies, crankshafts and camshafts, bearings and connecting rod bearings, valves and components, fuel tanks, pistons, flywheel ring gears, tensioners, belts, turbochargers, carburetors, three-way catalytic converters, diesel injection systems, starters and accessories, and other engine system components. As an automotive system component, the oil-water separator is an essential part of heavy-duty vehicles such as trucks, vans, and tankers, designed to separate oil and water in fuel. Its main function is to remove water from diesel fuel, reducing injector malfunctions and extending engine life. However, current oil-water separators often lack water level sensors, leading to situations where the separated diesel fuel contains some water or vice versa, resulting in fuel waste and affecting the separation efficiency. Therefore, an oil-water separator with a water level sensor is needed. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides an oil-water separator with a water level sensor. This solves the problem that current oil-water separators, due to the lack of a corresponding water level sensor function, easily lead to the separation of diesel fuel containing some water or water containing some diesel fuel during the oil-water separation process, resulting in diesel fuel waste and affecting the oil-water separation effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil-water separator with a water level sensor, comprising a fixed base, a lower separator shell fixedly mounted on the top of the fixed base, an upper separator shell mounted on the top of the lower separator shell, bolts on the surface of the upper separator shell, an inlet pipe fixedly mounted on the top of the upper separator shell, a filter element movably mounted on the inner wall of the upper separator shell, a water level sensor fixedly mounted on the inner wall of the lower separator shell, a controller fixedly mounted on the surface of the lower separator shell, a servo motor fixedly mounted on the inner wall of the fixed base, an agitator blade connected to the output end of the servo motor, a feed pipe fixedly mounted on the surface of the lower separator shell, a sealing cap threadedly connected to one end of the feed pipe, a drain pipe fixedly mounted on one side of the lower separator shell, and an oil drain pipe fixedly mounted on the other side of the lower separator shell.

[0005] Preferably, the upper shell of the separator is connected to the lower shell of the separator by bolts, and the number of bolts is six.

[0006] Preferably, the output end of the servo motor passes through the fixed base and is connected to the stirring blade, and the stirring blade is located inside the lower shell of the separator.

[0007] Preferably, the controller is electrically connected to the water level sensor.

[0008] Preferably, a first control valve is fixedly connected to the surface of the drain pipe, and a second control valve is provided on the surface of the oil drain pipe. The first control valve and the second control valve are electrically connected to the controller, respectively.

[0009] Preferably, the surface of the fixed base is provided with mounting grooves, and the number of mounting grooves is two.

[0010] Preferably, the surface of the inlet pipe is provided with threads, and the top of the inlet pipe is provided with a sealing sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The water level sensor can monitor the water level in the lower shell of the separator in real time and transmit the monitored water level information to the controller. The controller can control the first control valve to open the drain pipe. After the drain pipe is opened, the water separated in the lower shell of the separator can be discharged through the drain pipe. Since the water level sensor monitors the water in the lower shell of the separator in real time, after the water in the lower shell of the separator has been discharged, the controller can control the first control valve to close the drain pipe, thereby preventing the diesel fuel in the separator from being discharged with the water, avoiding diesel fuel waste, and ensuring the oil-water separation effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides the following technical solution: an oil-water separator with a water level sensor, including a fixed base 1, a lower separator shell 2 fixedly installed on the top of the fixed base 1, an upper separator shell 3 set on the top of the lower separator shell 2, bolts 4 set on the surface of the upper separator shell 3, an inlet pipe 5 fixedly installed on the top of the upper separator shell 3, a filter element 6 movably installed on the inner wall of the upper separator shell 3, a water level sensor 7 fixedly installed on the inner wall of the lower separator shell 2, a controller 8 fixedly installed on the surface of the lower separator shell 2, a servo motor 9 fixedly installed on the inner wall of the fixed base 1, an agitator blade 10 connected to the output end of the servo motor 9, a feed pipe 11 fixedly installed on the surface of the lower separator shell 2, a sealing cap 12 threadedly connected to one end of the feed pipe 11, a drain pipe 13 fixedly installed on one side of the lower separator shell 2, and an oil drain pipe 15 fixedly installed on the other side of the lower separator shell 2.

[0021] After the oil-water separator is installed, diesel fuel enters the upper shell 3 of the separator through the inlet pipe 5 and falls into the lower shell 2 of the separator through the filter element 6 inside the upper shell 3. The filter element 6 filters the injected diesel fuel, intercepting impurities. After the diesel fuel falls into the lower shell 2, the feed pipe 11 is opened through the sealing cover 12, and the oil-water separator is then added into the lower shell 2 through the feed pipe 11. After the oil-water separator and diesel fuel enter the lower shell 2, the servo motor 9 starts, driving the stirring blades 10 inside the lower shell 2 to rotate. During the rotation, the stirring blades 10 can stir the oil-water separator and diesel fuel, ensuring thorough mixing. After mixing, the water contained in the diesel fuel is separated, with the separated diesel fuel on top of the water, while the water is at the bottom of the lower shell 2. After oil-water separation, the water level sensor 7 can monitor the separation in real time. The water level inside the lower shell 2 of the separator is monitored and the monitored water level information is transmitted to the controller 8. The controller 8 can control the first control valve 14 to open the drain pipe 13. After the drain pipe 13 is opened, the water separated in the lower shell 2 of the separator can be discharged through the drain pipe 13. Since the water level sensor 7 monitors the water in the lower shell 2 of the separator in real time, after the water in the lower shell 2 of the separator is discharged, the controller 8 can control the first control valve 14 to close the drain pipe 13, thereby preventing the diesel in the separator from being discharged with the water, avoiding diesel waste, and ensuring the oil-water separation effect. After the water is separated and discharged, the controller 8 can control the second control valve 16 to open the oil drain pipe 15, so that the separated diesel can be discharged through the oil drain pipe 15. The oil-water separator is added together with the diesel added to the heavy-duty vehicle to meet the periodic addition standard. The fuel tank of the heavy-duty vehicle is large and the diesel is used for a long time. The oil-water separator and diesel addition time are also relatively long. All electrical equipment in this device is powered by an external power source.

[0022] In one aspect of this embodiment, the upper shell 3 of the separator is connected to the lower shell 2 of the separator by bolts 4, and there are six bolts 4. After the operator loosens the bolts 4, the upper shell 3 of the separator and the lower shell 2 of the separator can be disassembled, thereby completing the disassembly of the oil-water separator and facilitating the further processing of the filter element 6 inside the separator. Conversely, the upper shell 3 of the separator and the lower shell 2 of the separator can be assembled by bolts 4 to realize the assembly of the oil-water separator.

[0023] In one aspect of this embodiment, the output end of the servo motor 9 passes through the fixed base 1 and is connected to the stirring blade 10. The stirring blade 10 is located inside the lower shell 2 of the separator. After the servo motor 9 is started, the servo motor 9 can drive the stirring blade 10 inside the lower shell 2 of the separator to rotate, thereby realizing the stirring treatment of oil and water and oil-water separator in the lower shell 2 of the separator.

[0024] In one aspect of this embodiment, the controller 8 is electrically connected to the water level sensor 7, which can transmit water level information from the lower housing 2 of the separator to the controller 8.

[0025] In one aspect of this embodiment, a first control valve 14 is fixedly connected to the surface of the drain pipe 13, and a second control valve 16 is provided on the surface of the oil drain pipe 15. The first control valve 14 and the second control valve 16 are electrically connected to the controller 8 respectively. The controller 8 can control the first control valve 14 and the second control valve 16 through the water level information in the lower shell 2 of the separator to realize the discharge of oil and water, so that the water can be accurately discharged.

[0026] In one aspect of this embodiment, the surface of the fixed base 1 is provided with an installation groove 17, and there are two installation grooves 17. The operator can install the fixed base 1 onto the car through the installation grooves 17 to install the oil-water separator.

[0027] In one aspect of this embodiment, the surface of the inlet pipe 5 is provided with threads, and a sealing sleeve is provided at the top of the inlet pipe 5. An external connecting pipe can be threadedly connected to the inlet pipe 5 to facilitate the injection of diesel into the separator. The sealing sleeve is used to improve the sealing performance between the external connecting pipe and the inlet pipe 5.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
