Abstract
The utility model relates to a plate frame type dynamic filtering concentrator, comprising a machine frame, a feed plate, filter plates, a discharge plate, and a propping device. The utility model is characterized in that one end of each filter plate is all provided with a material through hole; one end with the through hole of two adjacent filter plates is arranged in mutually staggered way so as to form a continuous material circulating channel. The utility model has the advantages of simple and reliable sealing, continuous material circulating channel, small flow resistance, large filtration rate, and high particulate collecting rate. The utility model can continuously discharge the dense pulp. The utility model can realize the closed operation and the utility model has high automation level.
Description
The utility model relates to a kind of continuous filtration thickener, is in particular a kind of plate and frame filter thickener.
At present, existing filter thickener, the Flow of Goods and Materials resistance is big, and filter area is little, and treating capacity is little.
The purpose of this utility model is exactly to provide a kind of can realize the plate and frame dynamic filtration thickener of dynamic two-sided filtration continuously for the above-mentioned defective that solves prior art.
Technical solution of the present utility model is as follows:
A kind of plate and frame dynamic filtration thickener, it is protected and draws together organic frame, feedboard, reclaiming plate, filter plate, filter frame and holding device, it is characterized in that being equipped with the material through hole at an end of each filter plate, adjacent two filter plates have an end of material through hole to be staggered each other, form a continuous logistics corridor.
Advantage of the present utility model is to seal easy, reliable, and logistics corridor is continuous, and flow resistance is little, and filtering rate is big, and granule capturing rate height can be discharged continuous underflow, realizes closed-loop operation, the automaticity height.
The utility model will be further described below in conjunction with accompanying drawing:

Figure 10 is the utility model flow direction of material schematic diagram.
As shown in Figure 1 and Figure 2, the utility model includes frame 21, feedboard 1, reclaiming plate 2, filter plate 8, filter frame 7 and holding device 22, during work, Fig. 3-6 is feedboard 1 or reclaiming plate 2, and feedboard 1, reclaiming plate 2 are the single face filter plate, and charging through hole 3, counter-flushing liquid through hole 4 are arranged on the feedboard 1, discharge opening 9 and counter-flushing liquid hole 10 are arranged on the reclaiming plate 2, this hole 10 is a non through hole, into and out of the flitch below filtrate drain drilling 5 is arranged all, and this hole can external stop valve 6.As shown in Figure 9, filter frame 7 is provided with independently and filter plate 8 corresponding counter-flushing liquid through holes 4, and it plays the effect of backwash liquor flow channel, be communicated with the counter-flushing liquid through hole 4 of adjacent filter plate 8, form the backwash passage,, reduce equipment dismounting number of times for filter medium 20 provides backwash.Establish steam vent 12 at filter frame 7 tops adjacent with reclaiming plate 2, exhaust when being used for the original driving of equipment reduces vapour lock, but steam vent 12 externally connected exhaust pipes 11 and air bleeding valve 13.As Fig. 7, shown in Figure 8, filter plate 8 both sides filtrates are discharged projection shape surface or the vertical strip groove of surface 17 for the dislocation of reporting to the leadship after accomplishing a task, and are convenient to the even distribution of backwash liquor on filter plate 8; Counter-flushing liquid through hole 4 downsides have inclined hole 14, make backwash liquor be uniformly distributed in filter plate 8 both sides; Filter plate 8 one ends have logistics through hole 15, and an end two sides of close material through hole 15 has half slot 16, are used for the sealing between filter medium and clear liquid discharge surface; The filter medium at material through hole 15 places of filter plate 8 adopts Ω type chuck 19 to clamp, and sealing is reliable, and self-locking property is good, does not have the machinery wearing and tearing, long service life.Filter plate 8 side-lowers (or lower end) have filtrate drain drilling 5, can realize free flow or undercurrent.Also can when the part filter medium damages, close the stop valve of corresponding filter plate 8 by being threaded or external outlet of other mechanical connections and stop valve, equipment is continuously-running still, has prolonged the operation cycle and has reduced the dismounting number of times.Figure 10 has an end of material through hole 15 to be staggered each other adjacent two filter plates 8 for filter assembling and logistics schematic diagram, forms a continuous logistics corridor 18.After slip is entered by feedboard 1 continuously concurrent flow cross each filter chamber, slip obtains continuous filtration and concentrates, slip after concentrating is discharged filtrate by reclaiming plate 2 and is discharged by each clear liquid outlet, 20 of filter mediums are compressed by the outer rim of Ω type chuck 19 and filter plate 8, filter frame 7 correspondences, sealing is reliable, the application of on the utility model, succeeding of easy accessibility, dynamic filtration principle.When the needs backwash, close the purified liquor outlet valve of each filter plate 8 and the inlet valve on the feedboard, open the backwash liquor inlet valve, backwash liquor enters filter plates at different levels both sides continuously, the filter opening that blocks on the filter medium obtains backwash, backwash liquor sees through filter medium 20 and enters the slip flow channel, is finally discharged by the underflow outlet on the reclaiming plate.Filter medium 20 obtains in time, backwash fully, can reduce opening of device dismounting number of times, effectively guarantees the equipment long-period stable operation.
