Ultrasonic backwashing filter device for sewage treatment

Abstract

The invention discloses an ultrasonic backwashing filter device for sewage treatment. The device comprises a filter barrel, a filter element, an ultrasonic oscillator, a water outlet, a top cover, a water inlet pipe, an outer cover and a water outlet pipe, wherein the filter element is installed in the filter barrel in a coaxial way; a base is installed at the bottom of the filter element, and thetop of the filter element is installed in the filter barrel by means of the top cover; the filter barrel is divided into two parts by means of the filter element, and the two parts comprise a sewagecavity positioned between the filter element and the filter barrel, and a clean water cavity positioned in the filter element; the filter barrel is connected with the water inlet pipe used for inputting sewage into the filter barrel; the water inlet pipe is provided with an electromagnetic valve of the water inlet pipe; a residue discharge pipe is connected with the bottom position of the filter barrel. The ultrasonic backwashing filter device has the beneficial effects that the ultrasonic oscillator works so as to send ultrasonic waves into the filter barrel, and the high-frequency vibrationcauses the impurities to fall off from the outer surface of the filter element; furthermore, when the flushing water is input, the rotation of a cleaning rod can be driven, so that the filter elementcan be cleaned by means of bristles; due to the cooperation of the cleaning rod and the bristles, the impurities on the surface of the filter element can be conveniently and efficiently cleaned.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an ultrasonic backwash filter device for sewage treatment. Background technique [0002] With the continuous development in recent years, especially the development of urbanization, the speed is amazing, but the construction of related facilities required for urban development is very slow, far behind the speed of urban development, especially for the treatment of sewage At present, most of the sewage is directly discharged after concentration. There are a lot of impurities and some nutrient-rich substances in the sewage. Discharging into nature will cause great pollution to the environment and destroy the natural ecological balance; the existing The treatment of municipal sewage requires the sewage to be filtered first, but after a period of time, impurities are easily attached to the surface of the filter element used for filtration, which affects the filtering effect of the filter e...

[0002] With the continuous development in recent years, especially the development of urbanization, the speed is amazing, but the construction of related facilities required for urban development is very slow, far behind the speed of urban development, especially for the treatment of sewage At present, most of the sewage is directly discharged after concentration. There are a lot of impurities and some nutrient-rich substances in the sewage. Discharging into nature will cause great pollution to the environment and destroy the natural ecological balance; the existing The treatment of municipal sewage needs to filter the sewage first, but after a period of time, the surface of the filter element for filtering is easy to adhere to impurities, which affects the filtering effect of the filter element. At this time, the filter element needs to be replaced and cleaned manually, which affects the filtration efficiency of sewage
