Description

Technical Field

[0001] The utility model relates to the field of filter paperboard testing, in particular to a deep filter paperboard testing device. Background Art

[0002] Eaton's deep filter paperboard test devices are used to evaluate the filtration performance and effect of deep filter paperboard at different depths under different conditions. These test devices are usually designed for use in laboratory environments to simulate the filtration process in real industrial applications. The speed at which the fluid passes through the filter paperboard can be used for detection. Therefore, Eaton's deep filter paperboard test devices are used to evaluate and optimize the key parameters and performance of the deep filtration process, thereby ensuring product quality and process efficiency.

[0003] In the specific Eaton deep filter paperboard test, currently only one piece of filter paperboard can be placed during the test. In actual applications, different types of filter paperboards are usually required for multi-stage deep testing. Therefore, multiple filters need to be connected in series, which not only requires a large amount of test liquid, increasing the filtration time, but also the test device is large in size, cumbersome to operate, high in cost, and low in efficiency. In addition, when different liquids and raw layers need to be tested separately, multiple sets of test devices need to be used for testing, which is not convenient for operators to use.
