五、工作原理
（1）正常工作
需过滤水由设备下部进入设备内的筛筒，经筛筒过滤，滤后水由设备侧面流出，过滤过程完成。但筛筒截留悬浮物的增多，设备的进出水压差升高，当压差达到设定值时，则自动清洗，不同的筛筒规格适用于不同的过滤精度。
（2）清洗方式
本设备采用负压吸吮器，负压吸吮器由一台减速电机带动，绕筛筒内壁作螺旋运动。负压吸吮器将筛筒表面的杂物吸吮，同时排出体外，清洗时间为1～3min。
（3）控制系统
过滤设备设置在线差压表，当压差达到设定值时，输出标准信号至电控柜。然后控制电动排污阀和负压吸吮器开始工作。

V. Working principle

(1) normal operation

The water to be filtered enters the sieve cylinder in the equipment from the lower part of the equipment, and is filtered through the sieve cylinder. The filtered water flows out from the side of the equipment, and the filtration process is completed.

The increase of suspended solids in the screen cylinder increases the pressure difference between the inlet and outlet of the equipment. When the pressure difference reaches the set value, it automatically cleans. Different sieve cylinder specifications are suitable for different filtration precision.

(2) Cleaning method

The negative pressure sucking device is adopted. The negative pressure sucking device is driven by a deceleration motor and moves spirally around the inner wall of the sieve cylinder. The negative pressure sucker sucks up the sundries on the surface of the sieve tube and excretes them out of the body at the same time. The cleaning time is 1 ~ 3min.

(3) control system

The filter equipment is equipped with an online differential pressure meter. When the pressure difference reaches the set value, the standard signal will be output to the electric control cabinet. Then the electric drain valve and the negative pressure sucker start to work.
