Working principle and structure of external scraper filter housing

November 29,2023

External scraper filter housing is an industrial filtration equipment, mainly used to remove solid particles and impurities in liquids.

Here is some basic information about external scraper filter housings:

External scraper filter housingworking principle:

Filtration process: When the liquid passes through the filter, the solid particles are trapped by the filter screen or filter basket, while the clean liquid passes through.

Scraper mechanism: The external scraper filter housing is equipped with a scraper mechanism, which is the unique feature of this filter. The scraper is usually located on the outside of the filter or filter basket, and is used to periodically remove solid particles attached to the filter, prevent filter blockage, and maintain efficient filtration.

Main features:

Automatic cleaning: The external scraper filter housing is usually designed to be self-cleaning, and the scraper automatically moves the filter surface periodically to remove particles attached to the filter screen.

Continuous operation: Thanks to the automatic cleaning function, the external scraper filter housing can achieve continuous operation without frequent downtime for cleaning.

Application: It is widely used in industrial applications that require liquid treatment, such as water treatment, chemical industry, food and beverage production.

Continuous liquid supply: When the external scraper filter housing is cleaned, the liquid supply to the system will not be interrupted to ensure the continuity of the production process.

Easy maintenance: Due to the automatic cleaning mechanism, maintenance is relatively convenient, reducing the need for manual intervention.
