Method for cleaning ceramic filter

Abstract

The invention relates to a method for cleaning a ceramic filter, which can facilitate maintenance of an ultrasonic transducer and has better cleaning effect. The invention adopts a technical scheme that: a filter plate of the ceramic filter is cleaned through the ultrasonic transducer. The method is characterized in that: a motor drives an ultrasonic transducer box to move up and down; the ultrasonic transducer box is positioned at different positions by controlling start or stop of the motor; and the filter plate is cleaned.

Description

A cleaning method for a ceramic filter technical field The invention relates to a cleaning method for a ceramic filter. Background technique Ceramic filter is a kind of concentrate dehydration equipment, which is widely used in metal mines and non-metal mines, such as iron ore, copper mine, gold mine, lead-zinc mine, phosphate mine, etc. Ceramic filter is a kind of high-efficiency and energy-saving solid-liquid separation equipment. It mainly uses microporous ceramic filter plate to dehydrate through vacuuming; microporous ceramic filter plate is a large-area porous ceramic filter plate with thin-walled hollow structure. The support ball is filled inside; the ceramic filter plate needs to be cleaned after being used for a period of time, and the cleaning is mainly performed by physical cleaning using ultrasonic vibration. In the prior art, the ultrasonic transducer box is fixedly installed at the bottom of the trough, causing the ultrasonic transducer box to be soaked i...

AI Technical Summary

Problems solved by technology

In the prior art, the ultrasonic transducer box is fixedly installed at the bottom of the trough, causing the ultrasonic transducer box to be soaked in the pulp for a long time, and the pulp is constantly stirred, causing frequent short circuits and wear of the transducer

Moreover, due to the small gap between the ceramic filter plate and the transducer box, the maintenance personnel cannot directly enter the tank to troubleshoot the ultrasonic transducer box. It is necessary to remove the ceramic plate for processing, and then install the ceramic plate after completion ;During the processing process, maintenance personnel are also required to cooperate under the silo, and the gap under the silo is also very small. Since it is impossible to install safety facilities, there are serious safety hazards

In addition, due to the fixed installation position of the ultrasonic transducer box, the ultrasonic transducer produces sound wave interference, and the positions of the peaks and valleys are fixed, so that part of the circular area of ​​the ceramic filter plate has no ultrasonic vibration and cannot be cleaned. After running for a period of time, the ceramic filter plate There will be black and white permanent regeneration blind spots
