The traditional filtering mechanism is a filter tank. The filter tank mainly installs filter cloth at the bottom or inside to filter the fuel oil. After a period of use, a certain amount of impurities adhere to the filter cloth. It is necessary to stop the oil supply to the filter tank, and then manually remove the filter cloth and replace it with a new one.

[0025] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1

[0026] like Figures 1 to 5 A fuel oil filtering device includes an oil tank 2, the bottom of the oil tank 2 is connected to an oil outlet pipe 201, a U-shaped sieve plate 208 is arranged in the oil tank 2, and the front and rear sides of the U-shaped sieve plate 208 are respectively connected to the front side wall and the rear side wall of the oil tank 2.

[0027] The inner cavity of the oil tank 2 is divided into an inner filter bin 211 and an outer filtrate bin 212 by a U-shaped sieve plate 208. An oil inlet 205 communicating with the inner filter bin 211 is provided on one side of the oil tank 2. The oil inlet 205 can optionally adopt a pipe structure to facilitate connection to an oil pipeline.

[0028] The front side wall of the oil tank 2 and the rear side wall of the oil tank 2 are respectively provided with a U-shaped baffle 209 arranged parallel to the U-shaped screen plate 208. The U-shaped baffle 209 is located inside the U-shaped screen plate 208 and forms a U-shaped guide gap 210 with the U-shaped screen plate 208. The guide gap 210 is controlled at 0.2 to 0.5 cm to adapt to the thickness of the filter cloth 1 used.

[0029] The two ends of the oil tank 2 are connected to the first bracket group 203 and the second bracket group 202 . Each bracket group consists of two brackets, which are respectively connected to the front side wall and the rear side wall of the oil tank 2 .

[0030] The first bracket group 203 is rotatably connected with a driving shaft 103. A motor 101 for driving the driving shaft 103 is provided on one side of the first bracket group 203. A reduction gear box 102 is connected between the driving shaft 103 and the motor 101 for transmission to reduce the rotation speed and improve the stability of rotation.

[0031] A driven shaft 104 arranged parallel to the driving shaft 103 is rotatably connected to the second bracket group 202 . A roll of filter cloth 1 is wound around the driven shaft 104 . The free end of the filter cloth 1 passes through the U-shaped guide gap 210 and is connected to the driving shaft 103 .

[0032] When in use: the produced fuel oil enters the inner filter chamber 211 through the oil inlet 205, then enters the outer filtrate chamber 212 through the sieve holes of the U-shaped sieve plate 208 after being filtered by the filter cloth 1, and then is output through the oil outlet pipe 201 and then transported to the fuel oil storage tank;

[0033] After a period of filtration, the filtered impurities will adhere to the surface of the filtering part of the filter cloth 1. By starting the motor 101 to drive the driving shaft 103 to rotate, the part of the filter cloth 1 with impurities attached will be wound around the driving shaft 103, and at the same time, the filter cloth roll on the driven shaft 104 will be pulled to unfold and pull the new filtering part into the inner filter chamber 211 for filtration.

[0034] The filter cloth 1 can be arranged in the inner filter bin 211 for filtering through the U-shaped screen plate 208 and the U-shaped baffle 209. When the filtering part of the new filter cloth 1 needs to be replaced, the attached dirt part is rolled up through the drive of the motor 101 and the synchronous rotation of the driving shaft 103 and the driven shaft 104, and the new filtering part is sent to the inner filter bin 211 for filtering. Compared with the traditional manual replacement of the filter cloth 1, the mechanization degree is higher, the use is more convenient, and the replacement efficiency is improved. Example 2

[0035] This embodiment is further optimized on the basis of the above embodiment, specifically:

[0036] like Figure 1 As shown in FIG. 5 , an outer box body 204 is provided at the oil inlet 205 outside the oil tank 2 . The oil inlet 205 is an overflow slot provided on the upper edge of the oil tank 2 . An oil inlet pipe 206 is connected to the outer box body 204 .

[0037] When the oil is introduced, the oil supply pipeline first pumps the oil from the oil inlet pipe 206 into the outer box 204, and then overflows the oil to the inner filter bin 211 through the oil inlet port 205. This can reduce the pressure of the oil entering the inner filter bin 211, so that the incoming oil is buffered, avoiding the impact damage to the filter cloth 1 caused by excessive oil inlet pressure, and avoiding the filter residue attached to the filter cloth 1 being flushed up by the high oil inlet pressure. The design is more reasonable and reliable.

[0038] A base 4 is arranged below the oil tank 2, and a group of vertical rods 3 for supporting and fixing the oil tank 2 are provided on the base 4. The bottom of the oil tank 2 is an arc-shaped structure, and the oil outlet pipe 201 is connected to the lowest point of the arc-shaped structure. This design makes it easier to discharge all the oil in the oil tank 2 from the oil outlet pipe 201.

[0039] like Figure 6A group of round rods 207 arranged at intervals are connected between the arc bottoms of the two U-shaped baffles 209. By adding a group of round rods 207, the filter cloth 1 is auxiliary limited to avoid bulging in the middle of the filter cloth 1 at the inner filter bin 211 due to the change in tension when the driving shaft 103 rotates with excessive tension or the pulling speed is too fast when a fault occurs. Example 3

[0040] This embodiment is further optimized on the basis of the above embodiment, specifically:

[0041] This embodiment further adds an electric control system, which includes a controller and a liquid level sensor 5. The liquid level sensor 5 is installed in the oil tank 2 to detect the liquid level of the inner filter bin 211. The liquid level controller and the motor 101 are electrically connected to the controller respectively.

[0042] The liquid level sensor 5 can be a plastic float type liquid level sensor 5 or a photoelectric liquid level sensor 5 .

[0043] During operation, when the filter cloth 1 of the inner filter chamber 211 is blocked or clogged, the liquid level of the inner filter chamber 211 will rise. The liquid level sensor 5 detects the rise of the liquid level and transmits a signal to the controller, which then controls the motor 101 to start, thereby replacing a new filter part of the filter cloth 1.

[0044] When the new filter part on the filter cloth 1 is sent into the inner filter chamber 211, the filtration becomes smooth, the liquid level will also drop, and then a signal is sent to the controller through the liquid level sensor 5, and the controller controls the motor 101 to stop rotating.

[0045] The liquid level sensor 5 cooperates with the controller to start and stop the motor 101, and the filter part of the filter cloth 1 is automatically replaced by utilizing the change characteristics of the liquid level, thereby improving the degree of automation and being more convenient and quick.

[0046] The present invention is not limited to the above-mentioned implementation modes. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
