Description

The coal separation filter press

The utility model relates to a kind of novel coal separation filter press of coal separation sector application.

The coal separation filter press that uses partly is made up of host machine part and filter plate at present, its filter plate is many by cast iron, reinforcing bar rubber, polypropylene material is made, cast iron is too heavy, polypropylene is softer, intensity is low, influence is used, moreover its handle of the device for discharging of existing filter press is nigger, because the arm-tie car that stops of nigger once can only draw one, efficient is lower, for supporting heavy fuselage filter plate, have to be equipped with many supporting legs, the existence of these eyes in the middle of the particularly existing filter press crossbeam, influenced the free overhanging of outlet pipe greatly, make outlet pipe have length that weak point is arranged, and it is dirty to cause filter press filtrate and filter cake to mix, and influences the normal use of filter press.

The purpose of this utility model is exactly to provide a kind of novel coal separation filter press at above-mentioned situation.

The purpose of this utility model is achieved like this, and each supporting leg in the middle of the existing filter press crossbeam of cancellation only keeps crossbeam two ends stand leg, makes the outlet pipe of all filter plates all can be free overhanging, the length unanimity.Its filter plate handle adopts the long and short two kind, and short handle does not influence the operation of arm-tie car, filter plate high strength polyethylene mold pressing filter plate, such as molecular weight 1,500,000 with the polyethylene moulded board of super high molecular weight, intensity height, good toughness, acid and alkali-resistance, corrosion-resistant, anti-aging, in light weight, nonpoisonous and tasteless, surfacing is smooth, good airproof performance, and the filter cloth spoilage is extremely low.Other structures are all with existing filter press.

The utility model is in light weight, and is simple in structure, easy to use, and the life-span is long, and high efficiency once can draw filter plate more than two, and overcome filtrate and the mixed dirty common fault of filter cake.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is structure front view of the present utility model (preceding two filter plates is cut open).

Fig. 2 is the utility model structure vertical view (because of a left-right symmetry, second half cut-away section of the half-sum of only drawing).

Fig. 3 is an A-A position sectional view among Fig. 1.

Fig. 4 is an end nigger concave structure figure.

Fig. 5 is the short handle concave structure of end figure.

Fig. 6 holds grip structure figure level with both hands.

Fig. 7 is flat roller grip structure figure.

Fig. 8 is recessed roller grip structure figure.

Fig. 9 is the vertical roller shaped johning knot composition of one group of two filter plate.

Figure 10 is the folding type johning knot composition of one group of two filter plate.

Figure 11 is ternary filter plate connection layout.

By shown in Figure 1, its structure of the utility model is, a plate 4 is equipped with at the two ends of crossbeam 7, tailgate 10, polylith filter plate 6 is equipped with in the centre, be filter cake groove 9 between two filter plates, outlet pipe 16 is housed on the groove filter plate, the hydraulic jack 1 of crossbeam one end, the sprocket wheel 2 that drives through motor rotates through the sprocket wheel 8 that chain 3 drives the crossbeam other end, on the chain 3 between plate 4 and the tailgate 10 arm-tie car 5 is housed, shifting block 12 and back shifting block 13 before being equipped with on the arm-tie car 5, on the preceding shifting block 12 spring 11 is arranged, back shifting block 13 can fall down when preceding shifting block 12 erects, preceding shifting block erects when falling down, crossbeam 7 two ends are installed on the supporting leg 15, through handle basic 14 nigger 18 or short handle 19 are housed respectively on the two ends of filter plate 6, be connected with nonrigid connector 17 on nigger 18 and the short handle 19, spill handle matrix peace shape handle matrix is adorned at each filter plate two ends respectively, as Fig. 4, Fig. 5, Fig. 6 or Fig. 7, handle shown in Figure 8 is in structure, nonrigid connector can be a chain link, it also can be straight rod body, folded piece etc., as Fig. 9, Figure 10, shown in Figure 11, there is centre bore 20 at the filter plate center, filter plate adopts molecular weight to make at the polyethylene pressing plate of the super high molecular weight more than 1,500,000, draw the needs of polylith filter plate for adaptation, the length at filter plate two ends, short handle can adopt Fig. 7, adorn recessed version of rolling 22 peaceful rollers 21 on the matrix shown in Figure 8, its filter block as required can two one group, and if triplets or tetrad are two one group, handle is that one is long and the other is short, if triplets, handle is a unexpected misfortune, if tetrad is long three weak points, by that analogy, or the like.

Working condition of the present utility model is, when driving the arm-tie car, hydraulic motor moves to right, the filter plate of stirring first belt length handle moves to left, because of the second piece filter plate of its nigger with the short handle of band connects with flexible chain link, so, drag two filter plates simultaneously and move to left, regulate the length of chain link, adjusting the size of two filter plate spacings, when being pulled to Board position for first, be obstructed, hydraulic jack pressure raises, control by pressure switch, hydraulic motor is reverse, and the arm-tie car weight newly moves to right, because be short handle (having clipped the outer end) on second filter plate, so not influencing the arm-tie car moves to right, until being shifted to the right to the 3rd filter plate, repeat action for the first time, hold the 3rd, the 4th filter plate moves to left, one is long and the other is short is one group for every handle, draw two, if draw three, handle can be unexpected misfortune at every turn, or the like, once draw one group of discharging, so go round and begin again, till pulling.

Claims (2)

1, a kind of coal separation filter press, be a plate (4) to be housed at the two ends of crossbeam (7), tailgate (10), polylith filter plate (6) is equipped with in the centre, be filter cake groove (9) between two filter plates, outlet pipe (16) is housed on the groove filter plate, hydraulic jack (1) by crossbeam one end rotates through the sprocket wheel (8) that chain (3) drives the crossbeam other end through the sprocket wheel (2) that motor drives, on the chain (3) between plate (4) and the tailgate (10) arm-tie car (5) is housed, preceding shifting block (12) and back shifting block (13) are housed on the arm-tie car (5), on the preceding shifting block spring (11) is arranged, it is characterized in that said crossbeam (7) two ends are installed on the supporting leg (15), through handle matrix (14) nigger (18) or short handle (19) are housed respectively on the two ends of filter plate (6), nigger (18) and short on (19), being connected with nonrigid connector (17).
