Product Description

Scraping Auto Self-Cleaning Filter


Product Introduction
TPX series self-cleaning filter (TPX Filter for short), is the high efficiency scraping self-cleaning filter removing the impurities particles on the filter element outside by mechanical scraping, it continuously filters on-line. TPX filter is designed for fine and accurate filtration ranging from 50-500 micron. It can avoids extruding and breaking the impurities and is capable of the filtration for water and liquids viscosity up to 800000cps.
Working Principle
The liquid enters the filter from the inlet(1), flows through the filter element(6) from outside to inside. The filter element bottom is connected to the outlet(2), through which the liquid flows out. After the filter element captures the impurities, the cleaning action is trigger by the preset time or differential pressure value. The gear motor(4) drives the scraping blades(7) to rotate and remove the impurities on the filter element outside surface. The impurities moves off along the blades and falls down to the filter bottom. The rotating plates push the gravity impurities into the collection chamber(5). The impurities are collected at the filter bottom and in the collection chamber. The discharging valve open per the preset time and discharging the waste liquid with high impurity concentration through the drain outlet(3), the purged liquid can be reclaimed if necessary.
Technical Features and Advantages
Automatic 24-hour on-line filtration, no frequent changing out and cleaning
No disposable filter media consumption, save filter media cost and environment cost
Stainless steel scraping blade, good impurity removing performance

Filtering Process

Raw water enters the inside of the screen-cylinder from the filter's Inlet and flows through the screen to the filter's Outlet. The dirt particles are trapped on the inner screen surface and formulate a "filtration cake" that causes a differential pressure across the screen.

A pressure differential switch senses the pressure differential and when it reaches the pre-set value, the cleaning process begins.

Self Cleaning Process

During the self cleaning process, filtered process water continues to flow. The Drain Valve opens and the Motor rotates the stainless steel brush which sweeps the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the brushes and flushed out the drain valve.

The whole process takes 20-30 seconds. 
During the whole process water supply is uninterrupted.

Control System
Two types of control boards are available for the A700 filters: PLC/Timer.
The self cleaning cycle begins under any one of the following conditions 

1. Receiving a signal from the Pressure Differential Switch

2. Time interval parameter set at the control board

3. Manual Start
