[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1 A cleaning oil filtration and circulation device includes an oil storage tank 1, an old oil circulation tank 2, a coarse filter 3, a medium filter 4, an adsorption fine filter 5, and a nano-membrane permeation filtration membrane group 6. The bottom of the old oil circulation tank 2 is provided with an oil outlet pipe 7, and an electric pump 8 is threadedly connected to the oil outlet pipe 7. A flow sensor 11, an overflow valve 12, and a solenoid valve 13 are threadedly connected to the end of the oil outlet pipe 7 near the electric pump 8.

[0019] In this embodiment, the oil outlet of the electric pump 8 is connected to the oil inlet of the coarse filter 3. A heater 9 and a vacuum dewatering device 10 are provided between the electric pump 8 and the coarse filter 3. The heater 9 can raise the temperature of the oil and improve its fluidity, which is beneficial for subsequent filtration. The vacuum dewatering device 10 can remove water from the cleaning oil. The coarse filter can filter out large particulate contaminants in the cleaning oil. The oil outlet of the coarse filter 3 is connected to the oil inlet of the intermediate filter 4 through a microparticle enlarger 14. The microparticle enlarger 14 is used to agglomerate small particles into larger particles, which facilitates filtration.

[0020] In this embodiment, the oil outlet of the intermediate filter 4 is connected to the oil inlet of the adsorption fine filter 5. The intermediate filter 4 can filter out the micro-particles that have been agglomerated into larger particles. The adsorption fine filter 5 is used to adsorb and filter out the tiny particles in the oil. The oil outlet of the adsorption fine filter 5 is connected to the oil inlet of the nano-membrane permeation filtration membrane group 6. The oil outlet of the nano-membrane permeation filtration membrane group 6 is connected to the oil inlet of the oil storage tank 1 and the old oil circulation tank 2, respectively. The nano-membrane permeation filtration membrane group 6 obtains clean cleaning oil through nano-membrane permeation.

[0021] In this embodiment, pressure gauges 15 are provided in the coarse filter 3, the medium filter 4, the adsorption fine filter 5, and the nano-membrane permeation filtration membrane group 6. It also includes an intelligent control box 16, the output of which is connected to the input of the electric pump 8, the heater 9, the vacuum water outlet 10, and the solenoid valve 13, respectively.

[0022] In this embodiment, the recovered cleaning oil is first placed into the old oil circulation tank 2. The start button on the intelligent control box 16 is pressed, and the electric pump 8 starts working. The cleaning oil in the old oil circulation tank 2 is filtered sequentially through the electric pump 8 → flow sensor 11 → vacuum dehydrator 10 → coarse filter 3 → micro particle enlarger 14 → medium filter 4 → adsorption fine filter 5 → nano-membrane permeation filtration membrane module 6. The filtered cleaning oil enters the oil storage tank 1, and the unfiltered oil continues to return to the old oil circulation tank 2 for further filtration. This cycle continues until the old oil is completely filtered. The filtered cleaning oil can be reused after adding some additives, thereby reducing the cost of using the cleaning oil.

[0023] In this embodiment, the multiple filtration structure enables rapid and effective recycling and filtration of cleaning oil, thereby avoiding waste of cleaning oil and reducing the cleaning cost of accessories.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
