As shown in Figures 2 and 3, the shoulder in filter 4 and diaphragm plate 18 and arranged on left and right sides is provided with a pair of stiffener 29.The left and right shoulder of filter 4 and diaphragm plate 18 is clipped in this a pair of stiffener 29 with by compression state.On the upper surface of separately stiffener 29 suspender 30 has been installed, the upper end of this suspender 30 is provided with the vertical axis of guide 31.
The left and right axis of guide 31 is inserted as respectively in left and right two ends that a pair of filter cloth 39 that will mention the back is lifted on the cramp bar of using on filter 4 or diaphragm plate 18 forward and backward 35, is supporting above-mentioned cramp bar, makes its can up-down vibration.
Also have, as shown in Figure 4, on the left and right axis of guide 31, the spring 32 that flexibly supports cramp bar 35 has been installed below cramp bar 35, and the spring lock block 33 and 34 that embeds the top and bottom of this spring.In addition, cushion block 36 and the buffering rubber 37 that cramp bar 35 that flexibly restriction can up-down vibration is moved upward has been installed above cramp bar 35.In the upper end of the axis of guide 31 nut 38 is housed, splits away off from the axis of guide 31 to prevent cramp bar 35, cushion block 336 and buffering spring 37.
Like this, cramp bar 35 just can by means of spring 32 and buffering rubber 37 from two aspects up and down flexibly clamping.Described in hereinafter, filter 4 and diaphragm plate 18 separately after, when discharging filter cake, just the cramp bar 35 of up-down vibration is by cushion block 36 collision buffering rubber 37.This bump is suitably relaxed owing to cushion pad 37, passes to lifting filter cloth 39 thereon by cramp bar 35 again, thereby can impel filter cake to peel off fully.
The above-mentioned left and right axis of guide 31, by the spring 32 and the buffering rubber 37 that are installed on this axis of guide 31, and clamping cramp bar 35 of these springs 32 and buffering rubber 37 or the like, constituted the hanging apparatus of filter cloth 39.
As shown in Figure 5, be lifted on the filtering bottom board 4b of filter 4 and diaphragm plate 18 and the filter cloth 39 on the 19a and all have the long rectangular shape of above-below direction.Marginal portion and lower edge partly are respectively equipped with the end of filter cloth 39 pocket part 39a and the 3339b that unites by a seam after folding and form at an upper portion thereof.Filter cloth core tool 40 inserts among the pocket part 39a of upper rim, and the bottom rod member of using as weight 41 inserts among the pocket part 39b of lower limb part.
Middle body above filter cloth 39, with the stoste service duct 21 corresponding positions of the stoste service duct 11 of filter 4 and diaphragm plate 18 on, be provided with the opening 39c that when plate closing, is communicated with these stoste service ducts 11 and 21.On filter cloth shown in Figure 5 39,, fixed feed flow plate 42 with the liquid feeding channel 42a that when plate closing, is communicated with the stoste service duct 11 and 21 of filter 4 and diaphragm plate 18 at the peripheral part of opening 39c.
In addition, on the pocket part 39a of the upper rim of filter cloth 39, be provided with the breach 39d that the many suspension members 43 (referring to Fig. 2,3 and 4) on forward and backward for the cramp bar 35 that can will be vertically set on lifting filter cloth 39 pass.
The long-term use be used for the filter cloth on the filter press, if can produce the blocked problem in hole, so must regularly change.
As shown in Figure 6, in the time will being installed in filter cloth 39 on the cramp bar 35, earlier the suspension member 43 of cramp bar 35 is passed the breach 39d of filter cloth 39 upper rims, again filter cloth core tool 40 and the pocket part 39a that inserts filter cloth 39 upper rims of this filter cloth core tool 40 be placed in cramp bar 35 above, filter cloth core tool 40 is hung on the suspension member 43.Like this, filter cloth 39 is just floating to be located on the filtering bottom board 19a of the filtering bottom board 4b of filter 4 and diaphragm plate 18, and owing to the weight of feed flow plate 42 and bottom rod member 41 is subjected to pulling force.That is, owing to filter cloth 39 is not fixed on the filtering bottom board 19a of the filtering bottom board 4b of filter 4 and diaphragm plate 18, but be suspended on the cramp bar 35, so can load and unload at an easy rate.
When will filter cloth 39 when cramp bar 35 is taken off, the filter cloth core tool 40 that hangs on the suspension member 43 upwards being mentioned, just can from the breach 39d of filter cloth 39, extract the suspension member on the cramp bar 35 43, and the pocket part 39a of filter cloth 39 is lifted up.
As shown in Figure 7, be vertically set on the suspension member 43 of cramp bar 35 fronts, its upper end is rearward crooked, and is vertically set on the suspension member 43 of cramp bar 35 back, and its upper end is forwards crooked, has formed opposite U font respectively.Therefore, when filter 4 and diaphragm plate 18 discharged filter cake after separately, even the cramp bar 35 of filter cloth 39 and lifting filter cloth is because the bounce of spring 32 and tempestuously during up-down vibration, filter cloth core tool 40 can not split away off from the suspension member 43 of cramp bar 35 yet.
As shown in Figure 8, in the time of on filter cloth 39 being lifted on the filter 4 alternately arranged and diaphragm plate 18, be fixed with the filter cloth 39 of feed flow plate 42 as lifting on the front of filter 4 or diaphragm plate 18 or the face whichsoever in the back, then on its another face, lift the filter cloth 39 that only is provided with opening 39c, make between adjacent filter 4 and diaphragm plate 18, be fixed with the filter cloth 39 of feed flow plate 42 and the filter cloth 39 that only is provided with opening 39c relative to each other.
When filter 4 and diaphragm plate 18 are closed, be fixed on the feed flow plate 42 on the filter cloth 39, just embed in the recess 19b of the recess 4c of filter 4 and diaphragm plate 18.So, in the neutral gear of relative filter cloth 39, formed the filter chamber that the filtering bottom board 19a by the barrier film 19 of the filtering bottom board 4b of the filter after the closure 4 and diaphragm plate 18 separates.
In addition, the drainage channel 14 of the continuous filtrate that is made of the communicating pipe part 13 and 24 of filter 4 and diaphragm plate 18 then is communicated with the filtrate discharge pipe 10 of front baffle 1.
Replace in the filtration course of work of the filter press of arranging at filter 4 and diaphragm plate 18, stoste is by the stoste supply pipe 9 on the front baffle 1, be pressed into by the stoste service duct 11 of filter 4 and diaphragm plate 18 and 21 and the continuous stoste service duct that constituted of the liquid feeding channel 42a of feed flow plate 42 in.Bulged-in stoste is led to the bifurcated passage 42b on the lower surface of feed flow plate 42 by the inner circumferential surface from the service duct 42a of feed flow plate 42, distribute to supply to the filter chamber that forms between relative filter cloth 39.
Be pressed into the stoste in the filter chamber, be subjected to carrying the pressure of liquid, filter, make solid and fluid separation applications by filter cloth 39.The solid formation of stoste divides is caught by filter cloth 39, becomes filter cake and remains in the filter chamber.By the filtrate behind the filter cloth 39, be downward through after the filtering bottom board 19a of barrier film 19 of the filtering bottom board 4b of filter 4 and diaphragm plate 18, again by the osculum 12 of filter 4 and the osculum 23 of diaphragm plate 18, enter respectively with the communicating pipe drainage channel 14 that is communicated with of part 13 and 24 in, be extracted into machine exterior again.
Then, the penstocks 26 supply water under high pressures from diaphragm plate 18 expand barrier film 19, and further squeezing is deposited in the filter cake between the filter cloth 39.The filter cake that is squeezed is separated from the filter cloth 39 of diaphragm plate 18 1 sides owing to plastic deformation takes place in squeezing.
Finish after the above-mentioned press dewatering, just open the filter cake that the filter 4 that is arranged side by side and diaphragm plate 18 are discharged in the filter chambers.When opening filter 4 and diaphragm plate 18, the floating filter cloth 39 that is located on the filter 4 just breaks away from the filtering bottom board 4b of filter 4, so far, supporting from fore-and-aft direction by the filtering bottom board 19a of the barrier film 19 of the filtering bottom board 4b of filter 4 and diaphragm plate 18, the weight of filter cake, feed flow plate 42 and the bottom rod member 41 of being caught by filter cloth, completely all be added on the spring 32, by the cramp bar 35 that is lifting filter cloth 39 its compression.The filter cloth 39 of this moment is just with cramp bar 35, fall jointly attached to the filter cake on the filter cloth 39, feed flow plate 42 and bottom rod member 41.
Because this whereabouts, filter cloth 39, cramp bar 35, attached to the potential energy that the filter cake on the filter cloth 39, feed flow plate 42 and bottom rod member 41 are lost are just put aside on compressed spring 32, then, discharge as the energy that filter cloth 39 is risen again.Because energy is accepted and emitted to spring 32 repeatedly, that is, because the compression and the elongation of spring 32, filter cloth 39 is up-down vibration just, break away from from the filtering bottom board 4b of the filter 4 be close to and to come, and attached to the filter cake on the filter cloth 39, also because deadweight and peel off and split away off with filter cloth 39.In the process of filter cloth up-down vibration, lifting cramp bar 35 thereon is by cushion block 36 and yielding rubber 37 bumps.Because this bump can pass to lifting filter cloth 39 thereon by cramp bar 35, so can promote that filter cake splits away off all.
The decontaminating apparatus of filter cloth 39 has as lower member: as shown in Figure 7, be arranged on the top of each filter 4, have the cramp bar 35 of tetragonal hollow section; As shown in Figure 9, be separately positioned on the middle body of each cramp bar 35 and the clean nozzle 44 at three places below the both ends; Shown in Fig. 1 and 9, be erected at the clean water trunk line 46 on the support 45 that is arranged on front baffle 1 and the afterframe 2; And the clean water tube hose 47 that connects above-mentioned trunk line 46 and each cramp bar 35.
As shown in figure 10, the structure of each clean nozzle 44 is two form of bifurcation, and across top, the upper surface of filter 4, two jets of its lower end are respectively towards the forward and backward filtering bottom board 4b of filter 4.
As illustrated in Figures 5 and 6,, when filter cloth 39 is lifted on the filter 4, be equivalent to clean on the position of nozzle 44, be provided with breach window 48 on the top of filter cloth 39.When being lifted on filter cloth 39 on the filter 4, the end of clean nozzle 44 that can make two form of bifurcation is by this breach window 48, allows its jet protrude in the filtering surface of stoste one side of filter cloth 39.
Be supplied to the clean water of cleaning water trunk line 46, be assigned on each cramp bar 35, then,, eject from the jet of each clean nozzle 44 by the inside of each cramp bar 35 by cleaning water tube hose 47.
When the process of filtering is proceeded, and during the situation that the hole of filter cloth 39 take place to be stopped up, perhaps the residue of filter cake is residual attached on the surface of filter cloth 39 time, as shown in Figure 9, just eject from the clean nozzle 44 of two form of bifurcation from cleaning the clean water that water trunk line 46 is fed to the cramp bar 35, clean contaminated (filtering surface of stoste side) being lifted on the filter cloth 39 on the forward and backward filtering bottom board 4b of filter 4 simultaneously.
Because clean nozzle 44 is contained on the cramp bar 35 that lifts filter cloth 39 and becomes as a whole, does not have barrier on every side, so clean the adjustment angle of nozzle 44 and change operation all very convenient.In addition, the quantity of part has also reduced, and maintenance has also made things convenient for.
In addition, because cleaning nozzle 44 is arranged to as a whole with 18 one-tenth of filter 4 and diaphragm plates, so when even filter 4 and diaphragm plate 18 open or close, the jet of cleaning nozzle 44 still can keep relative position and the predetermined spray angle with respect to the pollution face of filter cloth 39.Therefore, be lifted on the even and stably wash clean of all filter clothes 39 on filter 4 and the diaphragm plate 18, reuse after can positively cleaning.
Shown in Fig. 1,2 and 3, below the cramp bar 35 left and right both ends above being arranged on filter 4 and diaphragm plate 18 near, be provided with a pair of vibrating shaft 51 that extends along guide rail 3.
As shown in Figure 1, former and later two ends of each vibrating shaft 51 are connected the bottom of the piston rod of cylinder 50 by connector 52, shown in Figure 11 and 12.Above-mentioned cylinder 50 is vertically set on the stand 49 of the and arranged on left and right sides wall that is fixed on front baffle 1 and afterframe 2, and its piston rod is towards the below.
The upper end of connector 52 by means of roughly parallel with the length direction of vibrating shaft 51, and the articulating pin 53 that along continuous straight runs extends, is connected rotationally with being installed in from the hang down fork-shaped end of bottom of the piston rod that comes of cylinder 50; The bottom of connector 52, by means of roughly the length direction with vibrating shaft 51 is vertical, and the pin 54 of along continuous straight runs extension, be connected on the end of vibrating shaft 51.
As shown in Figure 1, at the middle body of vibrating shaft 51 length directions, be provided with vibrator 55, it is to make vibrating shaft 51 whole vibrative vibrating devices.
Stripping performance at filter cake is poor, the deadweight that can not rely on filter cake itself is peeled off and still attached under the situation on the filter cloth 39, and some filter cake remains under the lip-deep situation of filter cloth 39, weight attached to the filter cake on the filter cloth 39 can be added on the cramp bar 35, the spring 32 of cramp bar 35 is being supported in compression from the below, so just sedimentation downwards of cramp bar 35.
At this moment, make the 51 vibrative whiles of vibrating shaft with vibrator 55, the piston rod withdrawal of all cylinders 50 makes the vibrating shaft 51 of and arranged on left and right sides rise, and allows the upper surface of vibrating shaft 51 contact with the lower surface at cramp bar 35 both ends.The cramp bar 35 of sedimentation like this, has downwards just been strengthened vibration owing to vibrating shaft 51 and has upwards been drawn.
Pass to the vibration of the vibrating shaft 51 of cramp bar 35, increased after the amplitude, pass to filter cloth 39 again, thereby can promote filter cake to strip down from filter cloth 39 owing to supporting the spring 32 of cramp bar 35.
