Fig. 1 is a schematic diagram of the present invention.
[specific embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in the figure, the ultrasonic cleaning equipment of membrane bioreactor includes membrane biological reaction pond 1, is provided with film system service sink 12 in described membrane biological reaction pond 1.Described membrane biological reaction pond 1 includes left pool wall 2 and right pool wall 3.Be disposed with a plurality of filter membrane spares 4 between left pool wall 2 and right pool wall 3, each filter membrane spare 4 be arranged in parallel.
Being provided with at the upper surface of left pool wall 2 and right pool wall 3 can forward and backward mobile portal frame 5, be provided with driving portal frame 5 forward and backward first drivers 8 that move in arm bottom, the left side of described portal frame 5, promptly first driver 8 drives portal frame 5 forward and backward moving, make portal frame 5 come correct position, first driver 8 can adopt motor-driven or alternate manner to drive.
Being provided with on described portal frame 5 can upper and lower mobile cross bar 6.On cross bar 6, be provided with can the be left and right mobile ultrasonic wave box body 7 that plays 4 effects of cleaning filter membranes spare, be respectively arranged with oscillating plate 8 in ultrasonic wave box body 7 forward and backward both sides.The described filter membrane spare that will clean 4 places between the oscillating plate 8 of both sides, and ultrasonic wave box body 7 is started working, cleaning filter membranes spare 4.Be provided with driving portal frame 5 upper and lower second drivers 9 that move on the right arm top of described portal frame 5, promptly second driver 9 drives cross bars 6 upper and lower moving, and makes cross bar 6 come correct position.Second driver 9 can adopt motor-driven or alternate manner to drive.
Be provided with on cross bar 6 and drive ultrasonic wave box body 7 left and right the 3rd mobile drivers 10, promptly the 3rd driver 10 drives ultrasonic wave box body 7 left and right moving, and makes ultrasonic wave box body 7 come correct position.
Described ultrasonic wave box body 7 comprises sealing box body 11, is provided with the piezoelectric ceramic ultrasound head that shakes in the box body 11 in sealing.The length of described sealing box body 11, width, thickness can be established according to MBR pond body actual size, described piezoelectric ceramic ultrasound shake the head ultrasonic frequency, a quantity of shaking and power can use corresponding welding procedure welded seal box body then according to the setting of ultrasonic wave cleaning strength.
As the optimal way of present embodiment, described ultrasonic wave box body 7 has a plurality of.
As the optimal way of present embodiment, described ultrasonic wave box body 7 has two.
As the optimal way of present embodiment, the material of described sealing box body 11 is stainless steel or titanium.
As the optimal way of present embodiment, on described left pool wall 2, be provided with guide rail 14, portal frame 5 can move along guide rail 14.
As the optimal way of present embodiment, on membrane biological reaction pond 1, be provided with the journey controller 13 of control first driver 8, second driver 9,10 actions of the 3rd driver.
The course of work of the present invention is:
Described ultrasonic wave box body 7 (a pair of or several to) is arranged on the cross bar 6 on the portal frame 5, and second driver 9 just can move, and ultrasonic wave box body 7 is raised up.After ultrasonic wave box body 7 raises up, move along the front and rear direction in membrane biological reaction pond 1 with driving.In filter membrane spare 4 positions that needs clean, portal frame stops and is fixed up under the control action of first driver 8.Again by second driver 9 control ultrasonic wave box bodys 7 dropping between the filter membrane spare 4 in the membrane biological reaction pond 1 slowly.At this moment the ultrasonic wave driving power is started working, and ultrasonic wave box body 7 sends the dirt (this moment, the film pipe still can be in running order) of the ultrasonic wave cleaning film tube-surface of setpoint frequency and intensity.
In the work of portal frame suspension drive system, ultrasonic wave box body 7 is done left and right direction motion, cleaning filter membranes spare 4 under the effect of the 3rd driver 10 simultaneously.At portal frame 4 operation tops and end journey controller 13 is arranged all simultaneously.First driver 8 quit work with the ultrasonic module vibrational system when ultrasonic wave box body 7 arrived end of travel.
At this moment, program control system is controlled 9 actions of second driver, promotes cross bar 6, and the oscillating plate on the ultrasonic wave box body 78 is lifted out the water surface (position that will be higher than filter membrane spare).Again according to the driven by program portal frame 4 operation a bit of distances of setting (moving on the adjacent other row filter membrane spare), to be hung with the filter membrane spare position that needs cleaning that drops to of ultrasonic wave box body 7 again, so just begin the on-line cleaning process of an other row filter membrane spare.The whole cleanings of filter membrane spare in the body of full pond are finished one time and are from the beginning carried out the cleaning process second time later on again.
If MBR pond body is that the volume in membrane biological reaction pond 1 is very big, when filter membrane spare is too many, can consider to use simultaneously the portal frame operation of two or many band ultrasonic cleaning systems, can guarantee cleaning performance and enough on-line cleaning time like this.
Lifting and conveying arrangement when simultaneously three-dimensional traveller gantry driving also can be used as the workbench of the current check of filter membrane spare and maintenance and the replacing of filter membrane spare can alleviate staff's labour intensity greatly, increase work efficiency.
Meaning of the present invention is to use minimum ultrasonic wave film pipe purging system is set, and reaches cleaning filter membranes spare effect to greatest extent, saves construction costs thus, improves filter membrane spare operational efficiency, prolongs filter membrane spare service life, reduces operating cost.By this full automatic on-line cleaning system, can guarantee the efficient operation of MBR system, filter membrane spare is carried out effective undamaged cleaning, can improve the water yield of system, and ensure the service life of filter membrane spare to greatest extent.
Portal frame can adopt the PLC programmable controller as central control system, adopts Hall switch or optoelectronic switch as Stroke Control and spacing, so system reliability is very high.And can adjust cleaning speed and intensity according to the actual conditions of filter membrane spare contamination and plugging at any time.
