Residue-free candle type filtering system

Abstract

The invention belongs to the technical field of filtering systems, in particular to a residue-free candle filter system. The filtering tank comprises a filtering tank main body, a material tank and aclear liquid tank; a filter bottom cone is arranged at the bottom end of the filter tank main body; the bottom end of the filter bottom cone is communicated with an upper butterfly valve; the bottom end of the upper butterfly valve is communicated with a straight-section pipeline; a bottom auxiliary filter element is connected into the straight-section pipeline in an embedded manner; the bottom end of the straight-section pipeline is communicated with a lower butterfly valve, the lower butterfly valve is communicated with a residue discharging pipe, the material tank is fixedly installed on one side of the filter tank body, the bottom end of the material tank is communicated with a material pump, and an outlet of the material pump is communicated with an inner cavity of the filter bottom cone through a feeding valve pipe. The straight-section pipeline is additionally arranged between the filter bottom cone and the residue discharging valve, the bottom auxiliary filter element embeddedin the straight-section pipeline is used for completely filtering residual liquid, and then the butterfly valve at the lower part is opened, so that residue liquid can be better discharged.

Description

technical field [0001] The invention relates to the technical field of filtration systems, in particular to a residue-free candle-type filtration system. Background technique [0002] Candle filter system is a relatively advanced, safe, efficient, and pollution-free new filtration method. Candle filter has the characteristics of high efficiency and energy saving, airtight high precision, easy maintenance, safety and reliability, and high degree of automation. It can be widely used in petroleum , plastics, electroplating, chemical, ceramics, pharmaceuticals, sugar and other industries for solid-liquid separation and filtration; candle filtration has gradually replaced pressure filter and bag filtration as the mainstream filtration method, and the repeated use of filter media saves A large number of filter consumables; the cylinder body is tightly sealed to ensure no leakage in the production process; the microcomputer automatic full-process control not only maintains the cont...

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a candle-type filter system without residual material, which solves the problem that the current candle-type filter system will have a certain amount of residual liquid that cannot be filtered out after each filter, and can only be refluxed to Raw material tank, then open the bottom butterfly valve to discharge slag, and the problem that the dry material attached to the main filter element inside the filter tank body cannot be quickly and effectively removed
