[0046] In the implementation of the present utility model, please refer to Figure 1-Figure 3 A filter element cleaning device comprises a base 1; a cleaning cylinder assembly is rotatably connected to the base 1 and is used to load the filter element, and a built-in steel brush 18 is provided on the cleaning cylinder; a steam delivery assembly is arranged at the lower part of the base 1 and extends into the cleaning cylinder assembly; a driving assembly is arranged on the base 1 and is connected to one end of the cleaning cylinder assembly to drive the cleaning cylinder assembly to rotate; an explosion-proof electric control box 13 is arranged on the base 1 and is electrically connected to the driving assembly.

[0047] Among them, see Figure 1 and Figure 3The steam delivery component includes a steam pipeline 6, which is externally connected to a steam generator and is provided with a plurality of air holes. When cleaning the filter element, the steam generator is started, and steam is continuously introduced into the cleaning cylinder assembly through the steam pipeline 6 to heat the medium water in the cylinder to boiling, thereby forming a temperature field to reduce the adhesion of oil and impurities on the surface of the filter element, thereby further improving the cleaning effect.

[0048] When in use, place the filter element in the cleaning cylinder assembly, add medium water, start the steam delivery assembly at the same time, introduce steam into the cleaning cylinder assembly, and drive the cleaning cylinder assembly to rotate. With the built-in steel brush 18 in the cleaning cylinder assembly, the stubborn oil stains on the filter element can be scrubbed. Through automated cleaning processing, the labor intensity and on-site operation and maintenance costs are reduced, the filter element cleaning quality and on-site production timeliness are improved, and environmental protection requirements are met.

[0049] In the embodiment of the present utility model, the driving assembly is an explosion-proof driving motor 14 , which is fixed to the base 1 by bolts and connected to the cleaning cylinder assembly by a coupling 12 .

[0050] In this example, see Figure 1-Figure 3 The cleaning cylinder assembly consists of an inner cylinder 11 and an outer cylinder. The outer cylinder consists of an outer cylinder protective cover 10 and an outer cylinder body 5. The outer cylinder body 5 is fixedly connected to the base 1 through a support 2. Similarly, the inner cylinder 11 is also provided with an upper and lower part, and the upper and lower parts of the inner cylinder 11 are connected as a whole through a hinge. The inner cylinder 11 is rotatably connected to the base 1 and accommodated in the outer cylinder, and the inner cylinder 11 is connected to the driving assembly through a coupling 12. When in use, the filter element is placed in the inner cylinder 11, and the inner cylinder 11 is fixed and locked by the hinge for cleaning.

[0051] Among them, see Figure 1 A rope traction pin 16 is also provided on the outer cylinder protective cover 10. The upper part of the outer cylinder and the lower part of the outer cylinder are connected by folding. A pulley block 9 and an outer cylinder protective cover elevator 8 are arranged on the base 1. One end of the wire rope is connected to the outer cylinder protective cover elevator 8, and the other end is wound around the pulley block 9 and connected to the rope traction pin 16. When the outer cylinder protective cover 10 is opened, the outer cylinder can be opened or closed by pulling the wire rope through the outer cylinder protective cover elevator 8.

[0052] It should be noted that, in this embodiment, please refer to Figure 1 The outer cylinder cover lifter 8 is a hand wheel type rotary adjustment mechanism and is provided with a wire rope winch. In addition, an electric adjustment mechanism can also be used to save manpower.

[0053] In this embodiment, during the cleaning process, please refer to Figure 3Since steam needs to be continuously introduced during the heating process of the device, steam water will inevitably overflow from the contact edge of the outer cylinder body 5 and the outer cylinder protective cover 10. Therefore, an overflow pipe 3, a collecting tank 15, and a guide tank 4 are arranged on the outside of the outer cylinder body 5. The collecting tank 15 is arranged on both sides of the cleaning cylinder assembly and is tilted to collect the steam water overflowing from the cleaning cylinder assembly; the overflow pipe 3 is connected to the collecting tank 15 and is tilted; the guide tank 4 is arranged on the cleaning cylinder assembly and is tilted, and the notch of the guide tank 4 is located at the outlet of the overflow pipe 3. Finally, a collection device can be arranged at the lower end of the guide tank to recover the steam water to avoid waste of resources.

[0054] Please note that Figure 2 The inner cylinder 11 is provided with a plurality of through holes 17 evenly spaced, so that the inner cylinder presents a screen, which facilitates the medium in the outer cylinder to enter the inner cylinder 11 to heat the filter element, and also facilitates the oil and impurities washed to be precipitated into the dirt collecting box 20 through the through holes 17 to collect the oil and impurities. The inner side of the inner cylinder is provided with a plurality of rows of evenly spaced built-in steel brushes 18. During cleaning, during the rotation of the cleaning cylinder, the built-in steel brushes 18 can brush the stubborn oil and impurities on the inner and outer surfaces of the filter element, thereby improving the cleaning quality of the filter element.

[0055] In this example, see Figure 1 and Figure 3 A dirt collecting box 20 is arranged below the outer cylinder body. The cross-section of the dirt collecting box 20 is a right-angled trapezoid, and the inclined end of the dirt collecting box 20 is located at the lower end. The steam pipeline 6 passes through the dirt collecting box 20 and is fixed; and a drain pipe 7 is also arranged on one side of the dirt collecting box 20, and a drain valve 19 is also arranged on the drain pipe 7. When cleaning, the drain valve 19 is kept closed so that steam can heat the water in the outer cylinder body 5 through the steam pipeline 6 to reduce the adhesion of oil and impurities on the surface of the filter element. After cleaning, the drain valve 19 can be opened to discharge the sewage through the drain pipe 7. In addition, when there are too many stains in the dirt collecting box 20, the inner cylinder 11 can be opened to flush and clean the dirt collecting box 20. By setting the inclined surface at the bottom, it can be ensured that the sewage is discharged more smoothly without forming a large area of ​​dirt.

[0056] In order to further illustrate the technical effect of the utility model, the specific implementation process of the utility model is as follows:

After the water volume is controlled to be about 300mm from the top of the outer cylinder body 5, operate the outer cylinder cover lifter 8 to drop the outer cylinder cover 10.

[0058] 2. Heating and cleaning: Turn on the steam generator, open the valve on the steam pipeline 6, introduce high-temperature steam into the steam pipeline, heat the medium in the cleaning cylinder, and reduce the adhesion of oil and impurities on the surface of the filter element through the temperature field. Turn on the control switch of the electric control box 13, and the explosion-proof drive motor 14 drives the coupling 12 and the inner cylinder 11 to rotate forward. When the inner cylinder 11 rotates, the friction force of the built-in steel brush 18 is used to clean the oil and impurities on the surface of the filter element. The cleaned oil and impurities are precipitated into the dirt collecting box 20 through the through hole 17 on the inner cylinder 11. The steam water generated by heating is collected from the overflow pipe 3 through the collection tank 15 and flows to the guide tank 4 for collection.

[0059] 3. Material removal and sewage discharge: After complete cleaning, turn off the switch of the explosion-proof electric control box 13, stop the explosion-proof drive motor 14, turn off the valve on the external steam generator and steam pipeline 6, and stop inputting steam. After the medium water in the cleaning cylinder cools down, shake the handwheel of the outer cylinder cover lifter 8, and the wire rope opens the outer cylinder cover 10 through the pulley group 9, open the inner cylinder 11, take out the cleaned filter element, and check the cleaning effect of the filter element. Use a high-pressure steam gun to clean the oil and impurities on the wall of the cleaning cylinder, let it stand, and after the oil and impurities are completely precipitated, extract the medium water in the cleaning cylinder (reuse), open the sewage valve 19, and discharge the oil and impurities in the sewage collection box 20 to the external device for unified treatment later.

The driving component is used to make the cleaning cylinder rotate continuously. The filter element can be thoroughly cleaned of stubborn oil stains and impurities on the surface of the filter element by the built-in steel brush under the rotation of the cleaning cylinder;

[0065] 4. More environmentally friendly and energy-saving: During the cleaning process, the cleaning cylinder is in a closed state, which avoids the splashing of oil and impurities on the surface of the filter element during the cleaning process. The device is equipped with a dirt collecting box. The cleaned oil and impurities are finally collected in the dirt collecting box after sedimentation.
