Energy.The board-washing 13 has washing function, is mainly provided with out liquid busway 2, filtrate effluent hole 3, filter plate sealing edge 4, filter
Plate feed opening 5, filter plate supporting point 6, filter plates face 7, four corner apertures 8 of filter plate, filter plate silk plug 9;It is characterized in that, by existing board-washing
Lower two corners double blind hole be modified to undercurrent through-hole；Filter plate silk plug 9 changes into quadrangle undercurrent for blocking the double free flow fluid holes of board-washing
Free flow water nozzle must be turned off manually before avoiding washing in form, simplify manual operation and be conducive to improve filter press automatization level.
The blind plate 12, has liquid function out, without washing function, be mainly provided with free flow water nozzle 1, go out liquid busway 2, filtrate goes out
Water hole 3, filter plate sealing edge 4, filter plate feed opening 5, filter plate supporting point 6, filter plates face 7, four corner apertures 8 of filter plate;It is characterized in that,
Free flow through-hole in pairs is improved into the lower two corners double blind hole of existing blind plate 12.
Described blind to wash the effect that fifty-fifty filter plate is respectively arranged and be: the double free flow water nozzles 1 of the lower two corners of blind plate are used as bright efflux, out
Liquid busway 2 is used as connection free flow water nozzle 1 and filtrate effluent hole 3 and converges filtrate, and filtrate effluent hole 3, which is used as, imports filtrate
Liquid busway 2, filter plate sealing edge 4 is used as sealing filter chamber, and (blind wash among fifty-fifty filter plate is equipped with filter cloth, and filter cloth periphery is sealing
Part), middle part filter plate feed opening 5 is used as material inlet port, and truncated cone-shaped filter plate supporting point 6 is used as supporting filter cloth and transmits pressure, blind
Net formula filter plates face 7, which is used as, to be increased filter cake frictional force and forms sepage water conservancy diversion network, and four corner apertures 8 of filter plate enters as cleaning solution
(when charging, filtrate flows to the dark efflux of four corner apertures 8 of board-washing 13 by upper two corner apertures 8 of blind plate 12 for mouth and filtrate (liquid；Washing
Or when drying, the valve of lower two corner apertures 8 of board-washing 13 is closed, and upper two corner apertures 8 of board-washing 13 is washed into cleaning solution or compressed air
When, cleaning solution, which has to pass through two corner apertures 8 on blind plate 12, just can guarantee that cleaning solution is passed between each board-washing 13), filter plate
Silk plug 9, which is used as, blocks the double free flow fluid holes of board-washing, changes into quadrangle undercurrent form.It adds Open valve 11, close valve 15, head
Filter cloth 16 is installed among tail anticorrosive board 14, board-washing 13 and blind plate 12, constitutes the diafiltration mechanism of diafiltration one, arrangement is mounted on pressure
On filter crossbeam, have the advantages that liquid speed degree is fast out, feed time is short, diafiltration is high-efficient.
Embodiment 2
A kind of diafiltration mode of high-efficient washing filter plate, the diafiltration integrated mechanism constituted using high-efficient washing filter plate of the invention,

Mode of washing is bidirectional crossed washing, and liquid mode is innovated as the double efflux forms of efficient light and shade out, in conjunction with 3 high-efficient washing of attached drawing
Mode of washing (process flow) schematic diagram of filter plate is described.
When feeding (static filtering), all valves 11 are switched on, free flow and the double effluxes of undercurrent light and shade, the height of feed opening 5
Press pump squeezes into slurry, carries out low pressure static filtering, and the particle that filter cloth 16 retains in material forms filter cake in filter chamber；Filtrate is passed through
Filtrate effluent hole 3 converges to liquid outlet channel 2, then goes out liquid from four corner apertures 8 in board-washing 13, can also be from 12 filtrate effluent hole of blind plate
3 converge to liquid outlet channel 2, then go out liquid from double free flow water nozzles 1, and liquid can more accelerate filtrate and go out liquid out than simple double frees flow 1 in this way
Speed effectively improves material filtering efficiency so as to shorten filter press filtration time.
When washing, two corners hole valve 11 in board-washing 13 is first opened, lower two corners hole valve 15 is closed, it is short to avoid water flow
Road, cleaning solution flow directly out；Cleaning solution is crossed into from upper two corner apertures 8 of board-washing 13, liquid outlet channel 2 is flowed through, from filtrate effluent
Hole 3 is flowed out, and filter cloth 16 and filter cake are penetrated, and is carried out two-way formula washing of eliminating illiteracy to filter cake, is efficiently removed the soluble impurity in filter cake,
Or the valuable mother liquor being detained in recycling filter cake, filtrate flow through blind plate 12 and flow out from double free flow water nozzles 1, substitute artificial hand completely
Free flow water nozzle 1 is closed in dynamic operation, is eliminated filtrate water clock when closing water nozzle, is effectively improved material washing effect.
When drying, compressed air is passed through by high-pressure medium hole (upper two corner apertures 8 of board-washing 13), passage of air dries up filter cake
Remaining cleaning solution in particle seam, bottoms out filter cake moisture content, improves the degree of purity of filter cake and the rate of recovery of mother liquor, together
The anhydrous filter cloth 16 of Shi Shixian regenerates.
High-efficient washing filter plate and its diafiltration mode of the invention, had not only improved diafiltration efficiency, but also to have tamped filter press automatic
Change basis, by PLC+ touch display screen intelligent control, single work cycle is (from compressing filter plate, feed, squeezing, wash, blow
Dry, pulling plate, discharging) key is automatically performed, improve filter press production efficiency.
