Description

Technical Field

[0001] The invention relates to the field of vacuum filters, in particular to a multifunctional combined filtrate valve multi-disc vacuum filter. Background Art

[0002] Multi-disc vacuum filter is a kind of equipment that uses vacuum as power to separate solids and liquids. It is widely used in dehydration operations in mining, chemical industry, environmental protection and other fields. Under the vacuum negative pressure of 0.04-0.07MPa, the liquid in the suspension is pumped away through the filter medium (such as filter cloth), while the solid particles are intercepted by the medium, thereby achieving the separation of liquid and solid. Solid particles larger than or similar to the pore size of the filter medium will form an initial layer on the surface of the medium in a bridging manner. The pores of this layer are larger than the medium channel and can intercept smaller particles. Then the solid particles gradually accumulate on the initial deposition layer to form a filter cake of a certain thickness.

[0003] When the impurities in the water discharged by the vacuum filter are filtered, the filter disc arranged inside filters the impurities, and the impurities are adsorbed on the filter disc to form a filter cake. As the filtration proceeds, the amount of impurities accumulated on the filter disc increases, which makes it easy for the filter disc to be blocked, affecting the overall filtering effect of the vacuum filter. It is necessary to stop the machine to clean the impurities and replace the new filter cloth, which is troublesome to operate and increases the workload of the staff. Summary of the invention
