150 micron mesh screen automatic Suction self cleaning filter to remove solid for cooling water

Product Overview

Description

Suction automatic self cleaning screen filter

 

Self Cleaning Filter is used for Continuous Unattended Filtration. Solid liquid separation in Sugar Industry was initially limited to very preliminary level of separation to basically removal of very large impurity particles. Hence, we have come up with fine filtration products for this Industry to cater different applications. Our Self Cleaning Filtration System is technologically advanced and meets the customers’ expectations. The professionally managed and highly experienced technical team of Micropore along with sugar technologists from the sugar industry carried out successful actual user trials to arrive at the benefits of fine filtration.

The filtration system is installed on the discharge of the pump for on line filtration, and the contaminated liquid flows through these filters, in series. The dirt particles are retained on the outer surface of the filter media and the clear liquid flows through. As the retention of dirt increases on the media surface the pressure drop increases across the filter, and at predetermined differential pressure the filter media approaches “dirty condition”.  

Our Liquid Filtration System is worldwide popular for being best in giving excellent performance and availability at market leading price in the market. The system basically consists of multi element filters in series, which are specifically designed for the following parameters

 

The suction type self cleaning screen filter is an easy-to-operate automatic plastic filter, with a self-cleaning mechanism driven by an electric motor. The filter is designed to work with various types of screens in filtration degrees ranging from 10 to 500 micron.

 

Filtering process:

Raw water enters the filter though the inlet valve into the screen cylinder. The raw water then passes through the filter from the inside out. Trapped dirt then forms a filter cake on the screens internal surface causing a differential pressure. The filter screen can be cleaned by continuous flushing or the cycle can be initiated by a predetermined time or differential pressure.

 

The Self-Cleaning Process:

The suction type self cleaning screen filter will start the self-cleaning process either when the pressure differential across the screen reaches a pre-set value or after a predetermined lapse of time. The fine screen filter element is cleaned by the suction scanner whose nozzles spiral across the inner surface of the screen. The filtration cake is “vacuumed” from the screen and expelled out the exhaust valve. The scanner’s spiral motion is achieved by a drive unit which rotates a bi-directional continuous worm shaft. The exhaust valve is activated For the duration of the cleaning cycle by a 3-way solenoid. Filtered water continues To flow downstream during the flush cycle, which takes approximately 16 seconds.

 

With the electric automatic self cleaning screen filter comes a series of automatic cleaning filters, designed for filtration of poor quality water to very fine filtration rates. The filter is automatically cleaned by suction scanners when a pressure differential (typically 0.5 bar) is sensed. The suction scanners vacuum the inside of the screen’s surface and  flush  any debris out the exhaust, using less than 1% of the total flow and without interrupting output. Filtration degrees between 10 and 800 micron and flow rates of up to 400 m³/h can be achieved. Higher flow rates can be achieved by banking multiple units.
