Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
A kind of filter-pressing method of the air pressure discharging of noresidue water, comprises the following steps:
Step 1:Material is pumped into filter chamber 31;
Step 2:To material press filtration, separation of solid and liquid is carried out;
Step 3:Block-by-block moves filter press plate, opens filter chamber 31, carries out discharging, until all dischargings of filter chamber 31 are completed;
As shown in Figure 5 and shown in Fig. 6, between step 2 and step 3, in progress purging line the step of residual water, it has
Body process is:All early gates 63 and late gate 64 on filter press plate are opened, the draining total valve 41 of preceding main sewer 43 is opened
And air inlet total valve 42 is closed, the draining total valve 41 of rear main sewer 44 is closed and air inlet total valve is opened, and makes gases at high pressure
From preceding main sewer 43 by filter chamber 31 and main sewer 44 is discharged after, by pipeline residual water discharge;Above-mentioned preceding draining
The switching sequence of the draining total valve 41 and air inlet total valve 42 of house steward 43 and rear main sewer 44 also interchangeable, makes gases at high pressure
Flow direction just on the contrary, also can reach the purpose of discharge line residual water.
During press filtration, drainage is only with Action of Gravity Field, it is difficult to drain only, has in the drainage residual purging line of part, long and long
It, pipeline can be lost its original function by serious erosion.Between step 2 and step 3, carry out in purging line
The step of residual water, make gases at high pressure from preceding main sewer 43 is by filter chamber 31 and main sewer 44 is discharged after, by pipeline
Residual water discharge so that residual water is discharged, and can reduce the moisture content of filter cake.If residual water is not discharged, unloaded next time
During material, residual water can be discharged on filter cake when air blowing discharging, improves the moisture content of filter cake, instead by the filter chamber 31
And make it that the effect of press filtration is worse.
Further, as shown in Figure 5 and shown in Fig. 6, in step 2, when carrying out separation of solid and liquid, the early gate of all filter press plates
63 and late gate 64 open, draining total valve 41 is opened, and air inlet total valve 42 is closed, and makes the water of separation of solid and liquid from the row of discharge outlet 46
Go out;In step 3, when being inflated to the filter press plate, the draining total valve 41 is closed, and air inlet total valve 42 is opened, and controls discharging
In the opposite side of filter chamber 31 early gate 63 and late gate 64 open, remaining early gate 63 and late gate 64 are all closed.
When carrying out separation of solid and liquid, the early gate 63 and late gate 64 of all filter press plates are opened, and are made every piece of filter press plate while are arranged
Water, improve the efficiency of draining;When being inflated to the filter press plate, the draining total valve 41 is closed, and air inlet total valve 42 is opened, control
The early gate 63 and late gate 64 of the opposite side of filter chamber 31 in discharging processed are opened, and remaining early gate 63 and late gate 64 all close
Close, filter press plate divides the effect of side discharge, improves the utilization rate of gas.
Further, as shown in 3 and Fig. 4, in step 3, block-by-block moves the filter press plate, after opening filter chamber 31, to this filter chamber
31 relative two pieces of filter press plates and side in filter chamber 31 is inflated, make its two pieces of described filter press plates in filter chamber 31
Side filter cloth outwards arches upward in arc-shaped.
The filter press plate is set to reach the effect of point side discharge, on the one hand, in the case of the high pressure gas of identical pressure, only
Filter press plate side therein is inflated, can fully improve the utilization rate of gas so that better, the opposing party of discharging
Face so that material can not be remained on the filter press plate, ensured that the sealing of filter press plate plate is good, increased making for the filter press plate
With the life-span, ensure its press filtration effect.
If high pressure gas is simultaneously towards the both sides of filter press plate, on the one hand, the utilization rate of gas can be wasted, discharging is insufficient, because
For this discharge way, gas is distributed in the both sides of filter press plate, and not as gas, to be distributed in side strong, causes discharging insufficient;Separately
On the one hand, if the both sides of the filter plates are passed through high pressure gas discharging simultaneously, distance between the filter press plate can be increased, it is permanent it
Afterwards, its sealing property can decline, material leakage when even resulting in its press filtration, lose original press filtration effect.
As shown in Figure 3 and Figure 4, using a kind of filter press plate of the filter-pressing method of the air pressure discharging of noresidue water, including press filtration
Plate body, provided with material channel 5 and drainage channel, the front and rear sides of the filter press plate are respectively equipped with filter cloth;
The filter press plate is provided with cavity, when filter press plate described in polylith is superimposed, shape between the adjacent filter press plate
Into filter chamber 31;
The filter chamber 31 is connected inside the drainage channel, outside passes through the filter press plate side communicated drainage house steward;
The main sewer includes preceding main sewer 43 and rear main sewer 44, and the preceding main sewer 43 and rear draining are total
Pipe 44 is respectively arranged with draining total valve and air inlet total valve 42;Make drainage channel except can be used for draining in separation of solid and liquid,
Also high-pressure air source can be passed through in discharging to be used to aid in discharging;The drainage channel is at least two, respectively connects the press filtration
The front side of plate and the preceding drainage channel 61 of rear side and rear drainage channel 62;The preceding drainage channel 61 is distinguished with rear drainage channel 62
Controlled by early gate 63 and late gate 64, and be respectively communicated with the preceding main sewer 43 and rear main sewer 44.
Material enters the filter chamber 31 by the pump of material channel 5, then carries out press filtration, and during press filtration, filter cloth plays filtering
Effect, the early gate 63 and late gate 64 of all filter press plates opened, and draining total valve 41 is opened, and air inlet total valve 42 is closed,
Due to the Action of Gravity Field of drainage in itself, drainage is before preceding drainage channel 61 and rear drainage channel 62 are flowed to described in the main sewer
Main sewer 43 and rear main sewer 44, discharged through the discharge outlet 46.The drainage channel is at least two, is respectively connected
The front side of the filter press plate and the preceding drainage channel 61 of rear side and rear drainage channel 62, the efficiency of draining can be increased.The front row
Supply mains 43 and rear main sewer 44 are respectively arranged with draining total valve and air inlet total valve 42, carry out residual water in purging line
The step of, make gases at high pressure from preceding main sewer 43 is by filter chamber 31 and main sewer 44 is discharged after, by the remnants in pipeline
Water is discharged so that residual water is discharged, and can reduce the moisture content of filter cake.It is residual when carrying out discharging next time if residual water is not discharged
Yu Shuihui is discharged on filter cake by the filter chamber 31 when air blowing discharging, improves the moisture content of filter cake, causes pressure on the contrary
The effect of filter is worse.
