Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, an ultrasonic automatic cleaning tubular filter comprises a housing 1 fixed with a filter tube 11, wherein the housing 1 is provided with an isolation chamber 2 at one side in the horizontal direction, and ultrasonic vibration heads 21 are uniformly arranged at one side of the isolation chamber 2 close to the housing 1 along the length direction of the filter tube 11; the left side and the right side of the lower end of the shell 1 are respectively provided with a water inlet 12 and a backwashing water outlet 13, and the left side and the right side of the upper end of the shell are respectively provided with a backwashing water inlet 14 and a backwashing water outlet 15.

The ultrasonic vibration heads 21 uniformly arranged in the length direction of the filter pipe 11 in the isolation chamber 2 can effectively clean dirt on the surface of the filter pipe. The ultrasonic cleaning principle, ultrasonic is a sound wave with frequency exceeding the human hearing range by more than 20 kHz. The longitudinal wave and the transverse wave are propagated in a fixed space, and only the longitudinal wave is propagated in the liquid, so that particle vibration is caused, and the acceleration of the particle vibration is proportional to the square of the ultrasonic cleaning rate. The water inlet flow path and the backwashing water flow path are arranged in a crossed and reverse mode, so that raw water can be effectively filtered through the filter pipe, and backwashing water can fully flush residual dirt in the filter.

In a specific embodiment, the housing 1 and the isolation chamber 2 are rectangular, a plurality of regularly arranged filter pipes 11 are arranged in the housing 1, and as shown in fig. 3, the ultrasonic vibration heads 21 arranged in the isolation chamber 2 are arranged along the width direction of the housing 1 and are consistent with the filter pipes 11. For fully rinsing the filter tube, in the embodiment of the utility model, the line number of ultrasonic vibration head 21 is the same with the line number of filter tube 11, and the filter tube can adopt acid and alkali-resistance corrosion-resistant 316 micropore filter tube, titanium pipe or ceramic filter tube, and the filter fineness is from 1-100 microns, preferably inorganic material filter tube, and the resistant ultrasonic wave of inorganic material filter tube washs repeatedly, can not lead to the fact destruction to the filter tube surface. The filter does not need to replace a filter material or a filter element, is convenient to operate and manage, and has low operation cost and wider application range.

As shown in fig. 4, the water inlet flow path flows from the raw water tank through the water guide pipe sequentially through the lift pump, the water inlet of the filter, the filter pipe, the water outlet of the filter and the water production tank; the backwashing water flow path flows through the backwashing pump, the backwashing water inlet of the filter, the filter and the backwashing water outlet of the filter from the water production tank through the water guide pipe in sequence.
