[0002] Diesel contains a certain amount of water. If the diesel is not separated from the oil in the diesel engine fuel system, it will cause irreversible damage to the engine, especially the high-pressure common rail injection system and the combustion chamber piston system. Separating the oil from the diesel can greatly increase the service life of the diesel engine and reduce the failure rate.

[0003] The oil-water separator structure is mostly single-stage filtration or double-stage filtration, and most of them are outside-in and inside-out filter elements. When the filter is working, the filter paper filters the fuel, removes large particles of impurities, and separates oil and water at the same time. However, since the length of the filter paper cover is not enough, when the diesel enters the tank, the diesel will wet the internal filter paper, thereby affecting the filtration quality of the filter paper, thereby reducing the filtering effect of the device and reducing the practicality of the device. This application proposes another technical solution to solve this technical problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A filtering mechanism of a fuel oil-water separator in this embodiment includes a tank body 1, a protective component is installed on the tank body 1, and a reinforcing fixing component is installed on the tank body 1.

[0024] Embodiment 1: The protection component includes an installation frame 2 fixedly installed inside the tank body 1, and two installation blocks 3 are fixedly installed inside the installation frame 2. Filter elements 4 are clamped on the tops of the two installation blocks 3, and a plug-in block is installed on the bottom of the filter element 4. A plug-in hole is opened on the top of the installation block 3, and the plug-in block is plugged with the installation block 3 through the plug-in hole to facilitate the installation and disassembly of the filter element 4. Filter paper 5 is fixedly connected to the outside of the filter element 4.

[0025] Among them, a connecting plate 6 is fixedly installed on the top of the filter element 4, and a paper core upper cover 7 is clamped on the top of the connecting plate 6. The paper core upper cover 7 is clamped with the connecting plate 6 through a clamping block, which is convenient for disassembly during maintenance after the installation, thereby improving the efficiency of maintenance.

[0026] In this embodiment, an annular baffle 8 is fixedly installed at the bottom of the paper core upper cover 7, and exhaust holes 9 are opened inside the annular baffle 8. There are three exhaust holes 9, and the exhaust holes 9 are evenly spaced inside the annular baffle 8. After the diesel is poured into the tank body 1, the air carried by the diesel is discharged to improve the filtering and separation quality of the device. A sealing gasket 10 is fixedly installed on the top of the paper core upper cover 7.

[0027] It should be noted that the filtering mechanism of the fuel oil-water separator, through the cooperation of the annular baffle 8, the sealing gasket 10 and the exhaust hole 9, allows the diesel to be protected above the filter paper 5 when entering the tank body 1, thereby reducing the diesel from wetting the filter paper 5, improving the use quality of the filter paper 5, facilitating the exhaust treatment when the diesel is poured in, and improving the filtering efficiency of the device.

[0028] Specifically, when the filtering mechanism of the fuel oil-water separator is in use, the diesel enters the tank body 1 through the first oil inlet hole, and the annular block prevents the diesel from flowing directly out of the tank body 1 through the gap and is discharged from the oil outlet 15. Then the diesel flows into the outside of the filter element 4 and the filter paper 5 through the second oil inlet hole and the screw plate 11. The annular baffle 8 protects the upper half of the filter paper 5 to reduce the wetting of the filter paper 5 when the diesel is poured in, thereby improving the use quality of the filter paper 5. The diesel is filtered through the filter element 4 and the filter paper 5 for oil and water treatment, and then discharged from the tank body 1 through the oil outlet 15.

[0029] Example 2: Please refer to Figure 1 On the basis of the first embodiment, a reinforced fixing assembly is further installed on the tank body 1, and the reinforced fixing assembly includes a screw plate 11 movably installed on both sides of the inner wall of the tank body 1, and two second oil inlet holes are opened inside the screw plate 11, and the positions of the two second oil inlet holes correspond to each other, so that the diesel can flow into the outside of the filter element 4 and then be filtered through the filter paper 5.

[0030] In addition, bolts are threadedly connected on both sides of the tank body 1, and the nut plate 11 is fixedly installed inside the tank body 1 by bolts, which is convenient for fixing and installing the nut plate 11 and also convenient for subsequent disassembly of the nut plate 11, thereby improving the efficiency of device maintenance.

[0031] In this embodiment, the top of the tank body 1 is threadedly connected to a tank cover 12, and an annular stopper is fixedly installed at the bottom of the tank cover 12, and the annular stopper is in contact with the nut plate 11 to reduce the diesel fuel from being discharged from the tank body 1 through the gap from the oil outlet 15 after it is poured into the tank body 1.

[0032] Among them, the inside of the tank cover 12 is provided with two first oil inlet holes, and the positions are corresponding, so as to facilitate the diesel to be poured into the tank body 1. A sealing ring 13 is fixedly installed at the bottom of the tank cover 12, and a reinforcing rib 14 is fixedly installed on the outer side of the annular baffle 8. The number of the reinforcing ribs 14 is eight and they are evenly distributed on the outer side of the annular baffle 8 to enhance the strength of the annular baffle 8 and extend the service life of the annular baffle 8. An oil outlet 15 is provided inside the tank cover 12.

[0033] It should be noted that, by installing the reinforcing fixing assembly, it is convenient to reinforce the annular baffle 8, thereby increasing the service life of the annular baffle 8 and further improving the use effect of the device.

[0034] Specifically, the filtering mechanism of the fuel oil-water separator is used by releasing the threaded connection between the tank cover 12 and the tank body 1, and then releasing the connection between the bolts and the nut plate 11, so that the device can be disassembled and repaired during inspection. The reinforcing ribs 14 strengthen the strength of the annular baffle 8 and extend the service life of the annular baffle 8.

[0035] The working principle of the above embodiment is:

[0036] (1) The filtering mechanism of the fuel oil-water separator is as follows: when in use, diesel enters the tank body 1 through the first oil inlet hole, and the annular block blocks the diesel from flowing directly out of the tank body 1 through the gap and is discharged from the oil outlet 15. Then, the diesel flows into the outer side of the filter element 4 and the filter paper 5 through the second oil inlet hole and the screw seal plate 11. The annular baffle 8 protects the upper part of the filter paper 5 to reduce the situation where the diesel oil soaks the filter paper 5 when it is poured in, thereby improving the use quality of the filter paper 5. The diesel oil is filtered through the filter element 4 and the filter paper 5 for oil and water treatment, and then is discharged from the tank body 1 through the oil outlet 15.

[0037] (2) When using the filtering mechanism of the fuel oil-water separator, the threaded connection between the tank cover 12 and the tank body 1 is released, and then the connection between the bolts and the nut plate 11 is released, so that the device can be disassembled and repaired during maintenance. The reinforcing ribs 14 strengthen the strength of the annular baffle 8 and extend the service life of the annular baffle 8.
