In present embodiment, operation principle and the pressure-filtering process of high pressure filter-pressing device are exemplified below:

(1) matched moulds, start flanging cylinder 7 and master cylinder 10, described movable beam slab 5 promotes all material moulds 3 and water mould 4 and fits tightly and realize matched moulds, adjacent material mould material containing part 22 and water mould material containing part 26 is made to form the filter chamber 35 closed, after matched moulds completes, close master cylinder 10, the thrust that flanging cylinder 7 provides is born by the frame of each mould completely, and the thrust of this flanging cylinder 7 is in the whole course of work, the oil pressure supplying it is constant, namely mold clamping force is constant, and it guarantees that framed matched moulds is reliable, can not leak material (see Fig. 6);

(2) pressure dehydration, mud is pumped into each filter chamber 35 from feed pipe 3 and feeding-passage 29, under the effect of feed pressure, part water in mud is by after expecting that mould filter cloth 23 leaches, material mould main sewer 12 is imported again through material mould guiding gutter 24, material mould osculum 27, material mould drainage channel 28, discharge filter chamber 35, the remainder in mud is trapped within filter chamber 35 and forms filter cake 36;

(3) extrusion dehydration, after pressure dehydration is maintained to setting-up time, close feed pipe 6, open high-pressure water pipe 8, in the rodless cavity 31 and each water mould 4 of pressure conversion cylinder 9, input the water under high pressure that pressure is 10-20MPa simultaneously, namely the high pressure up to 10-20MPa is produced in each water mould 4, this water under high pressure enters water mould 4 from intake tunnel 19, through water mould guiding gutter 21 evenly from punched-plate 17 through, barrier film rubber 16 is made to be subject to uniform action of hydraulic force, promote barrier film rubber 16 and extrude filter cake 36, the raffinate in filter cake 36 is made to be subject to high-pressure extrusion by expecting that mould filter cloth 23 leaches, again through material mould guiding gutter 24, material mould osculum 27, after material mould drainage channel 28 imports material mould drainpipe 12, discharge filter chamber 35, realize the further dehydration of filter cake 36, meanwhile, in the rodless cavity 31 of the water under high pressure input pressure conversion cylinder 9 in high-pressure water pipe 8, promote piston 32 when master cylinder 10 because of reveal or because the squeeze force in water mould 4 cause pull bar 2 be out of shape extend and decompression, input offset pressure oil in master cylinder 10, make the dynamic change with the variation in water pressure of squeezing of the thrust of master cylinder 10, and balance each other with the interior squeeze force produced of water mould 4 all the time, when stopping high pressure filter-press dehydration, there is the framed phenomenon of damaging by pressure or leaking material.

(4) die sinking and discharging, closes high-pressure water pipe 8, starts flanging cylinder 7 and master cylinder 10, and described movable beam slab 5 realizes die sinking, lays down the dry cake 36 in filter chamber 35, complete dehydration after pulling all material moulds 3 and water mould 4 to depart from.

The present embodiment employing pressure is that the water under high pressure of 10-20MPa implements extrusion dehydration operation to promote barrier film rubber 16 pairs of filter cakes 36, the hydraulic pressure (operating pressure of 2MPa can only be reached) that this hydraulic pressure adopts far above conventional barrier film water-strainer, therefore, on the one hand, the high pressure filter-pressing device that the present embodiment provides, mud directly can be pressed into stiff lump material, this dry cake is that hard plate is block, can not drying and directly pulverizing, not airborne dust in crushing process, do not tie cake, can directly use as other raw material, be convenient to transport and rear utilization, significantly save post processing cost, eliminate mud raffinate completely to the pollution of underground water, on the other hand, along with the significantly lifting of pressure, the squeeze force produced in water mould 4 also significantly promotes, this is for the mechanical strength of each parts of device, sealing properties etc. produce very large negative effect, therefore, when not increasing each part dimension of device, the present invention by the mode of thrust-balancing come offset pressure promote after on the mechanical strength of device and the impact of sealing, namely by arranging the pressure conversion cylinder 9 connecting high-pressure water pipe and master cylinder 10, its effect has two, the first converts hydraulic oil to water under high pressure, it two is: play supercharging, the diameter of usual master cylinder 10 can be more much smaller than water mould 4, want squeeze force that water mould 4 produces and the thrust that produces of master cylinder 10 balances each other, pressure then in master cylinder 10 is more much bigger than the pressure in water mould 10, and should relation be met: F squeezing=P hydraulic pressure* S water mould=F master cylinder=P master cylinder oil pressure* S master cylinder, be also P hydraulic pressure/ P master cylinder oil pressure=S master cylinder/ S water mould=(D 2-d 2) D 2,, wherein: P hydraulic pressurefor the hydraulic pressure in high-pressure water pipe, P master cylinder oil pressurefor the oil pressure in master cylinder 10, S water mouldfor the effective lifting surface area of water mould, S master cylinderfor the lifting surface area of master cylinder 10 piston, F squeezingfor the squeeze force in water mould, F master cylinderfor the thrust of master cylinder 10, D is piston 32 diameter of pressure conversion cylinder 9, and d is the diameter of the piston rod 34 of pressure conversion cylinder 9.

Water under high pressure in high-pressure water pipe 8 changes after cylinder 9 converts hydraulic oil to through pressure and is supplied to master cylinder 10, master cylinder 10 is made synchronously to produce thrust, the dynamic change with the variation in water pressure of squeezing of this thrust, and balance each other with the interior squeeze force produced of water mould 4 all the time, make each mould frame not by the impact of squeeze force, thus ensure framed closed good, do not leak material, also do not damage frame by pressure because of the impact of squeeze force.

After the autoclave diaphragm dewater unit adopting the present embodiment to provide carries out processed, the filter cake moisture content obtained with existing barrier film filter-pressing device contrasts as shown in table 1:

Table 1

Mud kind Moisture content after prior art press filtration Moisture content after the dehydration of this example The hydraulic pressure (MPa) that this example adopts Red mud ≥36% 19%~21% 9-12 Carbide slag ≥42% 20%~23% 8-10 Ceramic stone polishing mud ≥35% 14%~16% 8-10 Paper white sludge ≥38% 15%~18% 8-10 Ore dressing mud ≥30% 16%~18% 6-8

Visible through contrast, the filter cake obtained after adopting the present embodiment to dewater, the filter cake obtained after comparing the press filtration of system technology, its moisture content decreases by about 40%-50%, significantly improve the degree of drying of filter cake, simplify the subsequent treatment to filter cake, energy-saving and environmental protection, efficient.

The above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
