The specific embodiment

Be described further below in conjunction with the structure of accompanying drawing the filtration washing drier that the utility model proposed.

As depicted in figs. 1 and 2, be the structural representation of filtration washing drier.Its structure comprises upper cover lid 1, upper tank body 2, lower tank 3 and low bottom-disc 4, upper tank body 2 has charging aperture 21, discharging opening 22, leakage fluid dram 23 and washing inlet 24, be provided with filter core 5 near above the cavity 25 of upper tank body 2, and crossing filter core 5 and vertically be placed in the cavity 25 of upper tank body 2.Shown in Fig. 3 and 4, crossing filter core 5 comprises filtration outer net 51 and is positioned at the collector tube 53 that filtration outer net 51 inside and side have fluid port 52, be provided with liquid collecting room 54 below collector tube 53, this liquid collecting room 54 is communicated with the outside of upper tank body 2 by second catheter 6.As shown in Figure 5, be sintering screen pack 31, porous uniform board 32, air chamber 33 from top to bottom successively in lower tank 3, air chamber 33 is communicated with the Drainage pipe 35 of outside by first catheter 34 that passes low bottom-disc 4, on first catheter 34, be connected with fluidized gas inlet pipe 36, in low bottom-disc 4, be provided with heating arrangements 41.

In order to make the gas in the air chamber 33 evenly distribute, in air chamber 33, be provided with the gas distributor 36 of inclination.

Use this filtration washing drier to carry out the method for filtration washing drying, this method comprises the following steps:

The first step, reinforced

To need the liquid of filtration washing drying to import in upper tank bodies 2 and the lower tank 3 through charging aperture 21, maximum height can be a little less than the upper edge of crossing filter core 5;

The first step is filtered

In (one) step, extract filtrate out by top second catheter 6

Open the drawing liquid pump that is connected with second catheter 6, the filtrate that will be positioned at liquid collecting room 54 is extracted out, and the liquid level in upper tank body 2 is reduced to and crossed filter core 5 lower surface basically identicals, and the filter residue that filters out is attached to the outside of filtering outer net 51;

In (two) step, extract filtrate out by first catheter 34 of bottom

Open the drawing liquid pump that is connected with described first catheter 34, will extract out by the filtrate that sintering screen pack 31, porous uniform board 32 enter in the air chamber 33, the filter residue that filters out forms filter cake attached to sintering screen pack 31 upper surfaces;

In (three) step, the filter residue that filters outer net 51 outsides is blown down

Open the hair-dryer that is connected with described second catheter 6, to crossing filter core 5 inner air blowings, air-flow will be blown down the filter cake top of dropping on sintering screen pack 31 tops attached to the filter residue that filters outer net 51 outsides by second catheter 6;

The washing of the 3rd step

Cleaning solution or washing gas are fed on the filter cake of sintering screen pack 31 by washing inlet 24, and cleaning solution or washing gas purify the Impurity removal that can be dissolved in cleaning solution in the filter cake, and after sintering screen pack 31 filtered, cleaning solution flowed out through first catheter 34;

The 4th step, drying

(1) step heat drying

Feed hot water or vapours etc. in the heating arrangements 41 in low bottom-disc 4, will be arranged in the water evaporates part of filter cake above the sintering screen pack 31;

(2) step spouted fluidized bed drying

In air chamber, be blown into hot gas by first catheter 34, simultaneously second catheter 6 is opened, hot gas blows to filter cake by air chamber 33, porous uniform board 32, sintering screen pack 31, pressure is controlled at 3-6bar when initial, 700-1000mm water column during fluidisation, make that the powdery filter cake is blown afloat, the height that blows afloat is controlled at the 200-350 millimeter, until drying up;

The 5th step, discharging

Dried material is taken out through discharging opening 22.

In (two) the step fluidized bed drying operation in the 4th step, can outwards bleed by second catheter, hot gas blows to filter cake by air chamber, porous uniform board, sintering screen pack, pressure is controlled at 3-6bar when initial, 700-1000mm water column during fluidisation, make that the powdery filter cake is blown afloat, the height that blows afloat is controlled at the 200-350 millimeter, until drying up;

For better control rate of drying, in (two) the step fluidized bed drying operation in the 4th step, can outwards bleed by second catheter 6 simultaneously, hot gas blows to filter cake by air chamber, porous uniform board, sintering screen pack, pressure is controlled at 3-6bar when initial, and 700-1000mm water column during fluidisation makes that the powdery filter cake is blown afloat, the height that blows afloat is controlled at the 200-350 millimeter, until drying up.

In order to prevent that filter cake from hardening, in (two) the step fluidized bed drying operation in the 4th step, starting nozzle blows gases at high pressure on filter cake, can also start the helical stir breaker and quicken wet part of evaporation.And open method such as blast cap.

Protection domain of the present utility model not only is confined to the foregoing description, as long as structure is identical with the utility model filtration washing dryer configuration, just drops on the scope of the utility model protection.
