Membrane disc flux and bubble point detecting device

Abstract

The invention provides a membrane disc flux and bubble point detecting device. The membrane disc flux and bubble point detecting device is characterized in that the membrane disc flux and bubble pointdetecting device comprises a water tank, a base located in the water tank, three or more threaded columns connected to the base, nuts matched with the threaded columns for using, a lower clamping plate, a membrane disc, an air cylinder, an upper clamping plate connected to a piston rod of the air cylinder, a main pipeline, a first branched pipeline, a second branched pipeline, a first electromagnetic valve, a pressure gauge, a second electromagnetic valve, a flowmeter and a self-priming pump, wherein the first branched pipeline and the second branched pipeline communicate with the main pipeline, the first electromagnetic valve and the pressure gauge are sequentially mounted on the first branched pipeline, and the second electromagnetic valve, the flowmeter and the self-priming pump are sequentially mounted on the second branched pipeline. Through unique design, a membrane disc flux detecting device and a membrane disc bubble point detecting device are integrated, the performance detecting efficiency of the membrane disc is improved, the equipment cost is saved, and the workload of technicians is reduced; the ventilation and liquid pumping processes are controlled through the firstelectromagnetic valve and the second electromagnetic valve, and the utilization rate of the membrane disc flux and bubble point detecting device is increased; and the detecting device is provided with the air cylinder, the upper clamping plate and the lower clamping plate compress the membrane disc through the air cylinder without manual control, and thus convenience and rapidness are achieved.

Description

technical field [0001] The invention relates to the technical field of filter element performance testing for filtration and separation, in particular to a membrane disc flux and bubble point detection device. Background technique [0002] The filter element is the core part of the filtration separation system, which plays a vital role in the filtration and separation effect. The performance of the filter element will directly affect the efficiency of the entire system. The flux, pore size, and integrity of the filter element are all factors to judge the overall performance of the filter element. At present, the commonly used filter elements are pleated filter elements, wire wound filter elements, ceramic tubes, ceramic membrane discs, etc., among which there are few researches on ceramic membrane disc filter elements. [0003] At present, the device used to test the bubble point and flux of the filter element is only that the researchers directly test the bubble point and...
