Ultrasonic cleaning filter
Technical field
The present invention relates to the scheme of the cleaning method of the improvement of a kind of filter or filtering ponds, particularly filtrate.
Background technology
From fibrous nodules (containing the comet filtrate), the fibre bundle filtration technology till now of widely used always quartz sand filtration technology since the dawn of human civilization, and active carbon filter, ion-exchanger etc., water backwashing or air-water associating back-flushing method all adopted.This method is effective, but cleans consuming time generally being not less than 15 minutes, and water consumption is bigger.
Summary of the invention
The cleaning method that the purpose of this invention is to provide a kind of filter or filtering ponds.
In the present invention; Term filter comprises various filling bed type filters such as quartz sand filtration device, fibrous nodules and comet filtering material filter, fiber bundle filter, active carbon filter, ion-exchanger; The filter that had both comprised sealing also comprises unlimited filtering ponds, and they are referred to as filter.
Filter of the present invention; Comprise housing, be installed in the filter plate in the housing, filtrate, ultrasonic cleaning equipment; And be installed in water inlet and the delivery port on the housing; It is characterized in that filter adopts ultrasonic cleaning equipment that filtrate is cleaned, said ultrasonic cleaning equipment mainly is made up of supersonic generator, Vibration Box.
Being shaped as of said Vibration Box is plate shaped, has some apertures or slit on the Vibration Box, and the flat shape of Vibration Box and size are close with filtration water outlet side filter plate, near filtering water outlet side filter plate and setting in parallel.
Said Vibration Box be shaped as column, Vibration Box is vertical or insert in the filtering layer of being made up of filtrate with certain angle.
Said Vibration Box be shaped as column, Vibration Box near filter water outlet side filter plate and its axially and the water outlet side filter plate laterally arrange, Vibration Box can axially rotate under motor or hydraulic action.
Said Vibration Box be shaped as column, Vibration Box places in the protective cover, Vibration Box can radially rotate under motor or hydraulic action, Vibration Box inserts in the filtering layer of being made up of filtrate together with protective cover.
Said protective cover is processed by nonmetallic materials such as plastics, resin or stainless steel and other metal materials.
Method for suppersonic cleaning also can be united use with the air bump rinse operation method.
Ultrasonic cleaning filter of the present invention has the advantage that purging system is simple, cleaning performance is good.

The specific embodiment
Referring to Fig. 1; Filter of the present invention mainly comprises housing 1, is installed in the filtration water outlet side filter plate 3 in the housing 1; Be filled in the filtrate 2 that filters on the water outlet side filter plate 3; And be installed in the water inlet 8 and delivery port 9 on the housing 1, be installed on the housing 1 near the plate shaped Vibration Box 5 that filters water outlet side filter plate 3 and setting in parallel, supersonic generator 4.Have some apertures or slit on the plate shaped Vibration Box 5; Plate shaped Vibration Box 5 is connected with supersonic generator 4 through cable 6; Filtered water inlet side filter plate 31 is positioned at housing 1 top with water inlet 8, filters the bottom that water outlet side filter plate 3 and delivery port 9 are positioned at housing 1, and plate shaped Vibration Box 5 is positioned at the bottom of filtering water outlet side filter plate 3.
Operation principle is: during filtration, former water gets into from water inlet 8, evenly gets into the filtering layer of being made up of filtrate 2 from top to bottom, flows through filtering layer from top to bottom, through filtering water outlet side filter plate 3, delivery port 9 discharges.During cleaning; Backwash water gets into from delivery port 9, gets into the filtering layer of being made up of filtrate 2 from bottom to top through filtering water outlet side filter plate 3, flows through filtering layer from bottom to top; Discharge from water inlet 8; Filtrate 2 recovers loose condition (of surface), opens supersonic generator 4 and passes through plate shaped Vibration Box 5 to 2 ultrasonic waves of filtrate, and the suspension that absorption is trapped on the filtrate 2 is peeled off under action of ultrasonic waves and discharged with backwash water.
Referring to Fig. 2; Filter of the present invention mainly comprises housing 1, is installed in the filtration water outlet side filter plate 3 in the housing 1; Be filled in the filtrate 2 that filters on the water outlet side filter plate 3; And be installed in the water inlet 8 and delivery port 9 on the housing 1, vertically insert the column Vibration Box 51 in the filtering layer of forming by filtrate 2, supersonic generator 4.Fundamental difference embodiment illustrated in fig. 2 and embodiment illustrated in fig. 1 is the shape and the installation site of Vibration Box, and other is basic identical.
Operation principle: with embodiment illustrated in fig. 1 identical.
Referring to Fig. 3; Filter of the present invention mainly comprises housing 1, is installed in the filtration water outlet side filter plate 3 in the housing 1; Be filled in the filtrate 2 that filters on the water outlet side filter plate 3; And be installed in the water inlet 8 and delivery port 9 on the housing 1, near filtering water outlet side filter plate 3 bottoms and column Vibration Box 51 axial and that filtration water outlet side filter plate 3 laterally arranges, supersonic generator 4.A motor 10 is installed in the stage casing of column Vibration Box 51, and column Vibration Box 51 can axially rotate under motor 10 effects.Fundamental difference embodiment illustrated in fig. 3 and embodiment illustrated in fig. 1 is the shape of Vibration Box, and other is basic identical.
Operation principle: with embodiment illustrated in fig. 1 basic identical, difference is that column Vibration Box 51 axially rotates under the motor effect.
Referring to Fig. 4; Filter of the present invention mainly comprises housing 1, is installed in the filtration water outlet side filter plate 3 in the housing 1; Be filled in the filtrate 2 that filters on the water outlet side filter plate 3; And be installed in the water inlet 8 and delivery port 9 on the housing 1, vertically insert the column Vibration Box 51 in the filtering layer of forming by filtrate 2, supersonic generator 4.Column Vibration Box 51 places in the protective cover 511, and an end of column Vibration Box 51 is installed a motor 10, and column Vibration Box 51 can radially rotate under motor 10 effects, and column Vibration Box 51 inserts in the filtering layer of being made up of filtrate 2 together with protective cover 511.Fundamental difference embodiment illustrated in fig. 4 and embodiment illustrated in fig. 2 is that an end of column Vibration Box 51 installs a motor 10, and column Vibration Box 51 can radially rotate under motor 10 effects, and other is basic identical.
Operation principle: with embodiment illustrated in fig. 2 basic identical, difference is that column Vibration Box 51 axially rotates under motor 10 effects.
