Problems solved by technology

The filter bag type and filter element type filter have high filtration accuracy, but the filter cannot run continuously, and the filter bag or filter element must be replaced after the filter pressure difference exceeds the standard, which increases operating costs; the disc filter equipment is easy to install and can be backwashed online , but the filtering accuracy of the filter can only reach 20μ
American TEKLEEN self-cleaning filter has a filtration accuracy of up to 2μ, and has a variety of structures, which are suitable for installation in various situations on site. There are many control methods to realize online backwashing, but the filter is expensive, and ordinary users cannot afford it.
Because the price of this filter with the same treatment capacity is similar to that of reverse osmosis equipment, its application as a pretreatment filter for membrane water treatment equipment is limited.

Abstract

An in-line ultrasonic washing filter unit is composed of multiple filters with ultrasonic transducer, ultrasonic generator, differential pressure transmitter, PLC autocontroller, pipelines and control valves. Said filter consists of cylindrical body, hollow rotary shaft, drum-type filtering net, speed-reducing motor unit, and at least one ultrasonic transducer. Its advantages are high filtering precision, high automation level and high washing effect.

Description

technical field [0001] The invention relates to a precision filter for removing various impurities in water, in particular to an online ultrasonic cleaning and filtering device, which can be used as a preprocessor device for membrane water treatment equipment. Background technique [0002] The following types of filters are commonly used in the existing precision filters: fiber filters, filter bag filters, cartridge filters, disc filters. The fiber filter has high filtration precision, and the filter can be backwashed, but the equipment is bulky, requires sufficient installation space, and requires high energy consumption for operation. The filter bag type and filter element type filter have high filtration accuracy, but the filter cannot run continuously, and the filter bag or filter element must be replaced after the filter pressure difference exceeds the standard, which increases operating costs; the disc filter equipment is easy to install and can be backwashed online ,...
