arranged on barrier film 11, as shown in Figure 2, described barrier film 11, the press filtration frame group 5 that coaming plate 22 is adjacent with bottom surrounds a filter chamber 10, described coaming plate 20 is provided with the feed pipe interface 13 that supplies filtrate and cleaning solution to enter filter chamber 10, between described barrier film 11 and filter frame plate 14, be provided with water under high pressure import 18, thereby water under high pressure from water under high pressure import 18 enter backward presses against diaphragm 11 liquid in filtrate in filter chamber 10 is extruded and is realized press filtration function, described filter frame plate 14 is arranged on coaming plate 22, and filtrate frame 15 is fixed on filter frame plate 14, and the filter plate grid 16 of supporting filter cloth 7 is installed in filtrate frame 15, in filtrate frame 15, the bottom of filter plate grid 16 is provided with supersonic oscillations plate 17, five blocks of supersonic oscillations plates 17 and four microwave applicators 20 are at least installed in each press filtration frame group 5, the side of each microwave applicator 20 is all furnished with corresponding microwave controller 19, five blocks of supersonic oscillations plates 17 and four microwave applicators 20 are arranged in filtrate frame 15 at a distance of certain interleaved between the filtrate frame 15 of every filter frame and filter plate grid 16, its top has been placed with filter plate grid 16, and 7 of filter clothes are placed on filter plate grid 16.Microwave control cleaning solution enters filter chamber 10 from feed pipe interface 13, cleaning solution is filled with filter chamber 10, because liquid is filled with filter chamber 10, diaphragm of rubber 11 is lifted, the high-pressure extrusion water using during by press filtration is for the first time extruded from diaphragm of rubber 11 tops, cleaning solution enters delivery pipe after by filter cake and filter cloth 7, in this process, cleaning solution always contacts with supersonic oscillations plate 17, supersonic oscillations plate 17 produces ultrasonic wave, because supersonic oscillations plate 17 directly contacts with cleaning solution, ultrasonic wave is the propagation of density interphase in cleaning solution take cleaning solution as medium, due to nonlinear interaction, can produce cavitation, the shock wave sending when cavitation bubble is closed suddenly can produce thousands of atmospheric pressures around it, to pollution layer or the direct repeated stock of filter cake, in addition, ultrasonic vibration causes vibration velocity and the acceleration that particle is very large in cleaning solution, also make the dirt on filter cake and filter chamber surface be subject to frequent and fierce impact, thereby reached filter cake and the filter chamber cleaning performance of cleaning comprehensively, press filtration again after cleaning finishes, after finishing, press filtration carries out heating using microwave.Filter cake heating period feed pipe interface 13 and discharge tube 3 are all closed and are formed airtight chamber, microwave carries out heat drying to filter cake, because the water in filter cake is subject to thermal evaporation, diaphragm of rubber 11 is lifted, the water under high pressure of secondary extrusion is got rid of from water under high pressure interface, microwave penetrates filter cake and can be absorbed when inner, and its energy is instantaneous to be transferred heat energy to and filter cake (comprising nexine filter cake and contained moisture thereof) entirety is heated up.Now, nexine water vapour pressure rises sharply, under the driving of this pressure, steam is got rid of to material top layer, and first drying layer forms at filter cake internal layer, then expansion from inside to outside, realize the dry of filter cake, filtration cakes torrefaction device, according to the composition difference of filter cake, can be selected different power by microwave controller 19, temperature sensor 18 is the temperature in on-line measurement filter chamber constantly, thereby realizes the On-line Control to dry operating temperature.
During concrete enforcement, filter cloth drive unit 8 can adopt the structure shown in Fig. 3, also designed, designed as required, filter cloth drive unit shown in Fig. 3 mainly by left motor 15 ', right motor 18 ', belt 14 ', left driven roller 16 ', right driven roller 17 ', hold-down roller 13 ' composition, the left driven roller 16 of left motor 15 ' and right motor 18 ' by belt 14 ' drives correspondence separately ', right driven roller 17 ' rotation, and drive by the filter cloth 7 on their surfaces of hold-down roller 13 ' be pressed on and move, left motor 15 ' and right motor 18 ' rotating speed adjustable and be controlled by filter cloth correction device 9.Described filter cloth correcting device 9 mainly by two infrared generators 25 ' and two infrared receivers 24 ' and corresponding conventional control circuit form, two infrared generators 25 ' be arranged on respectively both sides of filter cloth, two infrared receivers 24 ' be also arranged on filter cloth 7 corresponding positions, both sides, infrared generator 25 ' and infrared receiver 24 ' be all contained on body 2 to limit the driving range of filter cloth 7, when filter cloth 7 sideslip, the infrared receiver 24 of one side ' will not receive infrared ray, so just control this side decelerating through motor, thereby two motor differentials make filter cloth 7 times just, as shown in Figure 4.Can designed, designed as the described filter cloth cleaning device 1 of one of water-saving result key technology, also can adopt the structure shown in Fig. 5, in Fig. 5, filter cloth cleaning device mainly by filter cloth clean upper deflector roll 23 ', filter cloth clean lower guide roll 20 ', water jet 21 ' and hairbrush 22 ' form, in filter cloth cyclic process filter cloth clean on deflector roll 23 ' and filter cloth clean lower guide roll 20 ' guide effect under filter cloth 7 from both sides hairbrush 22 ' between pass through, the water spray of water jet 21 ' constantly, hairbrush 22 ' effect under filter cloth 7 obtained effectively cleaning.
The cyclic process of whole filter cloth was driven by filter cloth drive unit 8 before this, through removable deflector roll 12 ' the realize tensioning of filter cloth, again by several cylinder deflector rolls 10 ' formation operating path, then through filter cloth cleaning device 1, filter cloth 7 is cleaned, finally by filter cloth correcting device 9, carry out tuningout and turn back to again on driven roller.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
