Description

Multifunctional checking device for filter element Technical Field The invention relates to the technical field of filter element inspection, in particular to a multifunctional filter element inspection device. Background The separation filter core of aviation oil needs to be checked and tested regularly to ensure the filtering effect, when the filter core is checked and tested, besides the appearance observation of the surface of the filter core and the detection of the hydrophobicity of the surface of the filter core, the internal ratio of the filter core is checked, and the internal polluted condition is observed to judge whether a new filter core needs to be replaced or not. When the filter element carries out a hydrophobicity experiment, whether the surface of the filter element is immersed or not is observed by carrying out water spraying on the surface of the filter element, in the process, water permeation is needed to be carried out inside the observation filter element, and under the condition that the outside of the filter element is not damaged, if the function of the filter element is perfect, water drops can not permeate the side wall of the filter element to enter the inner side wall of the filter element. The invention discloses a water spraying test method and a water spraying test device for a separation filter element, which are disclosed in Chinese patent publication No. CN114166697A, wherein the water spraying test method for the separation filter element comprises the following steps of horizontally laying the separation filter element on a fixing frame, adjusting the distance between the top surface of the separation filter element and a water outlet of a liquid spraying device to be 75mm through an adjusting device, moving the liquid spraying device to one end of the separation filter element, opening a switch of the liquid spraying device to enable water flow to flow down from two sides of an axis of the separation filter element, uniformly moving the liquid spraying device to the other end of the separation filter element, observing whether fine holes sprayed on the surface of the separation filter element of water penetrate or not, rotating the separation filter element by 45 degrees around the axis of the separation filter element until the separation filter element rotates for one circle, and retesting the separation filter element after cleaning if the separation filter element exists, and the water spraying test device for the separation filter element. The invention can simply and conveniently carry out a water spraying test on the separation filter element, and the water flow can be uniformly left at the highest position of the separation filter element with proper height when the water spraying is carried out by using the device, so that the influence of improper manual operation on the test result is avoided. However, the scheme is only used for the part of the water spraying test in the filter element inspection test, whether water enters from the side wall of the filter element or not can not be observed in the filter element during the water spraying test, the function of observing the inside of the filter element is also not available, the function is simple, and the inspection test on all performances of the filter element can not be met. Disclosure of Invention The invention aims to overcome the defects that the water spraying test method and the water spraying test device of the separation filter element in the prior art are only aimed at the water spraying test of the filter element, the function is single, and various performance inspection and test of the filter element cannot be met, and provides a multifunctional checking device of the filter element. The verification device provided by the invention not only can carry out a water spraying experiment, but also can test whether the water permeation phenomenon exists in the filter element during the water spraying experiment, and can also check the polluted condition in the filter element, thereby meeting the test of various performances during the periodic inspection of the filter element, and being simple and convenient to operate. The aim of the invention can be achieved by adopting the following technical scheme: The utility model provides a multi-functional verifying attachment of filter core, includes the frame, locates be used for placing the filter core support of filter core in the frame, locate be used for checking the inside endoscopic device of filter core on the filter core support, locate the frame is used for carrying out the drenching device of drenching for the filter core of fixing on the filter core support, be used for fixing the test paper fixed knot who surveys the water test paper and locate be used for in the frame the drive filter core is in around its own rotatory drive arrangement on the filter core support. The multifunctional checking device for the filter element provided by the inve
