刷式全自动自清洗过滤设备

, , , ,  ,  ,

刷式自清洗过滤器是一种内部置高强度滤网和不锈钢刮刷组件，采用自动控制和手动控制两种控制方法对过滤原液进行过滤、清洗、排污而达到净化目的的一种较精密过滤器。

 

组成部件

驱动部分、电控柜、控制管路（包括压差开关）、滤芯组件、清洗组件（刷式或吸刷式）、连接法兰等。

 

工作原理

待过滤液体经进口流入过滤器，从金属网内向外过滤，杂质被拦截在内表面。当滤器进出口压差达设定值或定时器达到设定时间时，控制器发出信号驱动电机转动刮刷清洗，同时排污阀打开。吸附在滤网上的杂质微粒被转动的钢丝刷或尼龙刷刷下，随水流从排污阀排出。清洗周期结束，电机停止运转整个过程中，物料不断流，实现了连续化、自动化生产。

 

Brush Self-Cleaning Filter

.

 

Feature

1. Filter precision from 50-3000μm,big filter area,high  age carrying capacity,customized product.

2. Simple turn-of-a-handle cleaning of the filter screen,adjust the parameter of the automatic cleaning system.Automatic cleaning.

3.Has motor overload protection, which can effectively protect the motor.

4.Eliminates the need for turning off the water and extracting the filter screen for rinsing.No interruption of the process water flow during cleaning,Low pressure loss:less than 1%.

5.Easy to maintenance,installation and disassemble.

6.Flange connecti  to the user’s pipeline, national standard flange, versatility.

 

Two types of cleaning method

Automatic co ol: there are two types:timing co ol and pressure difference. Set the filtration time on the filter timer, when it reaches the setting time, the brush will start cleaning  age,discharge time is also set by timer; while the system pressure co ol system with real-time user-defined pressure compared when the system pressure reaches the set pressure difference, the filter will start cleaning  age,  age discharge time set by the timer.The whole system returns to its initial state, prepare for the next filtration step.

Manual co ol: Press the manual button on the co ol panel, filters will start cleaning

 

Structure and wo ng principle

Automatic brush away filter is co ed of the drive mechanism, the co ol circuit (including the pressure switch), filter components, cleaning device, connecting flanges and other major component parts.It cleans  age by the drive motor and the electric valve automatically, the operation mode is automatic operation (option:manual operation), with timing co ol or pressure difference co ol. Its automated part is co olled by reliable PLC programmable co oller.

Water enters into the filter, the mechanical impurities are intercepted.When the impurities accumulate for a period,reaches 0.05MPa, then the differential pressure switch will send signal, while the PLC command is issued, transmission motor starts, the drain valve opens, the impurities de ited on the filter is brushed away,and drain out.The whole process is without personnel, without downtime. Besides, the device also has the function of timing and manual cleaning to ensure that the outlet water is safe under any circumstances.
