Description
Technical field
The present invention relates to filter field, more particularly to a kind of ceramic filter.
Background technology
Ceramic filter integrates the new and high technologies such as electromechanics, capillary ceramic plate, Automated condtrol, ultrasonic wave cleaning
Novel filtering device.Compact conformation, superior performance, economical, societal benefits are notable, can be widely applied to ore dressing, chemical industry, coal,
The solid-liquid separating equipment of the industries such as metallurgy, medicine, generating, environmental protection and sewage disposal.
Existing ceramic filter when striking off to the filter cake on ceramic wafer, commonly used technical scheme be by
Scraper is provided with fixed interval (FI) with ceramic wafer or scraper is contacted with ceramic wafer.But it is usual that scraper and ceramic wafer are provided with fixed interval (FI)
The filter cake on the gap between scraper and ceramic wafer can be led to can not to strike off, and the accuracy of manufacture of ceramic wafer is had must
Ask, if scraper is contacted with ceramic wafer, between scraper and ceramic wafer, friction can be produced, so that blade wears, the fortune of ceramic wafer
Turn frictional force to increase it is seen that both technical schemes all can not effectively filter to the filter cake on ceramic wafer and reliably use.
