Seal type plate filter with cleanable filter core cross section

Abstract

The invention discloses a seal type plate filter with a cleanable filter core cross section. A guide column (3) and a clutch rod (2) are longitudinally arranged in a box body (1), an outer closed pore plate pair (9), a filter core (8) and an inner closed pore plate pair (10) are sequentially and longitudinally arranged in the box body (1) in parallel from outside to inside along the guide column (3) and the clutch rod (2), the outer closed pore plate pair (9) and the inner closed pore plate pair (10) are respectively provided with at least two layers of parallel pore plates, longitudinal through holes are uniformly formed in each layer of pore plate, orthographic projections of holes in two adjacent layers of pore plates in a longitudinal direction are not mutually overlapped, the filter core is longitudinally compressed to be filtered when the pore plates are opened, and the filter is released for being transversely cleaned when fitted and closed, so that the long-term continuous and stable effect work of the whole plate filter is ensured, and equipment sealing and self-cleaning interaction works can be realized; meanwhile, the plate filter is special in design structure, simple and convenient to structure, convenient to operate, maintain and clean, economic and practical, small in volume, high in filtering efficiency, and excellent filtrate transparency and fineness.

Description

technical field

[0001] The invention relates to a B01D liquid material separation and filtration device, in particular to a plate filter with a cleanable sealed filter element section. Background technique

[0002] Plate airtight filter is a precision clarification and filtration equipment with high efficiency, energy saving and airtight operation. It is mainly composed of a filter host and some auxiliary equipment such as mixing caps, delivery pumps, pipelines, valves, and electrical control to form a complete filtration system. The filtration process depends on the medium to be filtered. The main body is composed of a filter tank, a filter screen, a cover lifting mechanism, and an automatic slag discharge device. After the filter aid is mixed with the material in the mixing tank, it is pumped to form a cake layer on the filter screen. Once a stable filter cake layer is reached, the fine filter aid particles can provide countless fine channels to trap suspended impurities....
