Description

Technical Field

[0001] The utility model belongs to the technical field of filter element cleaning, and in particular relates to a device capable of cleaning a filter element. Background Art

[0002] Filter element is a professional term for filtering and purifying functions. In order to purify the original fluid resources and separate the resources, the filter element is now mainly used in oil filtration, air filtration, water filtration and other filtration industries. The working principle is that when the fluid passes through the filter element with a certain precision, its impurities are blocked, and the clean fluid flows out through the filter element. After using the filter element for a period of time, a lot of oil or impurities will adhere to the surface of the filter element, causing blockage, affecting the filtering effect of the filter element. At this time, the filter element needs to be cleaned.

[0003] Filter elements are usually cleaned with ultrasonic cleaning equipment. The cleaning equipment used earlier directly put the filter element into the cleaning equipment without fixing the filter element. During the cleaning process, the filter element needs to be fixed by hand, and only one or two can be cleaned at a time, resulting in high labor intensity and easy fatigue of the staff. The cleaning efficiency of the filter element is low, and the filter element is easy to collide with the inner wall of the equipment, damaging the filter element. Utility Model Content

Because the liquid level in the body 1 overflows the positioning tube 31 and the filter element 8, the pressure of the liquid sprayed from the spray hole will not be too large, which only accelerates the vibration of the cleaning liquid and will not cause damage to the inside of the filter element 8, further improving the cleaning efficiency of the filter element 8. After that, after the cleaning liquid is discharged from the liquid output end tube 14, distilled water is injected to clean the filter element 8.
