Abstract
The utility model discloses a filter medium gas-liquid mixed backwashing device of a plate-and-frame filter press with a variable filter chamber, which comprises a filter pressing structure of the plate-and-frame filter press, a filter medium, drain holes or vent holes distributed in a bottom plate of a combined filter plate, a drainage or ventilation channel connected with the drain holes or the vent holes, a gas inlet main pipeline or a water inlet main pipeline connected with the drainage or ventilation channel, and a drainage magnetic valve, the filter medium gas-liquid mixed backwashing device is characterized by also comprising a gas-liquid mixed atomization mechanism, and the filter medium of the plate-and-frame filter press is backwashed by adopting gas-liquid mixing. The filter medium gas-liquid mixed backwashing device has the advantages that the washing speed is fast, the efficiency is high, the using quantity of washing liquid is small, the energy consumption is small, the washing quality is high, and the service life of the filter medium can be greatly prolonged.
Description
Technical field
The utility model relates to plate and frame filter press, specifically is the anti-cleaning device of a kind of change filter chamber plate and frame filter press filter medium gas-liquid mixed.
Background technology
At present; Common plate and frame filter press cleans or anti-cleaning device generally all is that washing or simple Compressed Gas clean; This cleaning way has the water that consumes or compressed-air actuated amount is bigger and it is not thorough to clean, thereby shortened the service life of filter medium greatly.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of prior art, and a kind of simple and reasonable, easy to use, anti-cleaning device of change filter chamber plate and frame filter press filter medium gas-liquid mixed that cleaning efficiency is high and effective is provided.
The utility model becomes the anti-cleaning device of filter chamber plate and frame filter press filter medium gas-liquid mixed; Comprise filter press filter-press arrangement, filter medium, be distributed in water flowing or passage, the water flowing that is connected with water flowing or passage or ventilation conduit on the combination filter plate base plate, and the air inlet that is connected with the water flowing or the conduit of ventilating or intake trunk line, drain solenoid valve; Different with prior art is: this anti-cleaning device also is provided with the gas-liquid mixed atomising mechanism, adopts gas-liquid mixed to clean the filter medium of plate and frame filter press is counter.
Described gas-liquid mixed atomising mechanism is made up of gas-liquid mixed atomizer and the air compression system, the cleaning fluid dosing system that are attached thereto, and the gas-liquid mixed atomizer is communicated with air inlet or water inlet trunk line through autocontrol valve.
Described cleaning fluid can be the special-purpose cleaning fluid of water or filter medium.
The course of work of the anti-cleaning device of this gas-liquid mixed is: the air pump valve of air compression system is opened, and the water injection valve of cleaning fluid dosing system is opened, and gas-liquid gets into gas-water mixer and mixes; Get into the gas-liquid trunk line through check valve, get into water flowing or passage through the gas-liquid conduit again, be ejected into the filtering layer back side of filter medium; Blow down dashing of gases at high pressure; The cleaning fluid rapid permeability is to the surface of filter medium, thereby after will getting lodged in tamper in the pore of filter medium surface and washing, closes check valve, air pump, cleaning fluid water injection valve; Drain solenoid valve is opened draining, accomplishes cleaning process.
The utility model has the advantages that: cleaning speed is fast, and efficient is high, and the cleaning fluid consumption is few, and energy consumption is little, and cleaning quality is high, can prolong the life-span of filter medium greatly.
