Description

A kind of clip type filter

Technical field

The invention belongs to solid material dehydration technique field, more particularly, to a kind of clip type filter.

Background technology

Disk filter is because it can work continuously, unit area treating capacity is big, take up an area the features such as small and be widely used in The dewatering operation of solid powder.There is by being drawn between gas-liquid-solid three-phase by particulate in the filter cake that filter cloth is filled for absorption during filtering The dynamic equilibrium that power, capillarity and surface tension of liquid are formed, and when filtering the rapid reduction of gas-liquid two-phase can destroy it is this Balance, so as to cause the gravitation between particle and particle to increase, gap reduces, volume contraction, causes filter cake that cracking occurs or splits Gap.After crack produces, not only air will communicate with vacuum, and air, which is inhaled into vacuum, reduces vacuum；And formed at crack Lower resistance air channel, by the vacuum short circuit of filter cake, filter cake cannot get negative-pressure vacuum suction, so as to filter cake moisture will not again under Drop.There is the problem of limit moisture in this disk filter for having resulted in relying solely on negative-pressure ward, also in filtering It is to say even if the negative pressure for giving its longer time blots the time, and its moisture can not be continued decline.This just needs us Exploitation one kind can prevent filter cake surface from producing crack, so as to realize that filter cake can continue be held by negative-pressure ward, filter cake moisture The continuous disk filter declined.

The content of the invention

It is an object of the invention to provide it is a kind of it is simple in construction, can effectively prevent filter cake surface from producing crack, so as to realize filter Cake can continue can be with the clip type disk filter of continuous decrease by negative-pressure ward, filter cake moisture.

A kind of clip type disk filter of the present invention is realized by following technical proposals：

The present invention a kind of clip type disk filter, including main shaft, be fixed on main shaft it is at least one along main shaft axial direction The filtering disk and slurry tank of arrangement, described filtering disk are made up of polylith filter fan, it is characterised in that：Also include being arranged on often The clamping sheet mechanism of individual filtering disk both sides and the fixation kit for tingle mechanism,

Described clamping sheet mechanism is that specular is arranged on a pair of intermediate plates that each filtering disk blots area, and each intermediate plate is by one Length is consistent with single filter fan length, and width is made up of 50mm-200mm elastic plate, on the top of described each intermediate plate Bolt hole A is provided with, the bolt of full thread is provided with the bottom of each intermediate plate, the intermediate plate is arc knot towards disk side is filtered Structure, the intermediate plate are remote along the distance of filtering disk rotational one lateral extent filtering disc face in the direction of the width, and inverse filtering disk turns The distance of dynamic lateral extent filtering disc face is near.

Described fixation kit is made up of upper stationary part and lower fixture,

Described upper stationary part is made up of a full wire bolt and two pairs of nuts I, and full wire bolt is through a pair of intermediate plate top Bolt hole A, and be respectively fixedly connected with the top of a pair of intermediate plates by two pairs of nuts；

Described lower fixture is made up of two support bars being symmetrically welded in filter main shaft shell and two pairs of nuts II, The top of each support bar is provided with bolt hole B, and the screw bolt of each intermediate plate bottom through bolt hole B and is arranged on support bar Inside and outside nut be fixedly connected with support bar.

Advantages of the present invention：

(1) clip type filter of the invention, filter cake can be carried out by the intermediate plate of each filtering disk both sides further Compacting, the aqueous vapor in filter cake is rapidly disappeared and filter cake is carried out compression before producing and lived again by crack, so as to reconstitute a kind of gas The solid three-phase equilibrium of liquid and avoid the crack of filter cake from producing, ensure that filter cake effectively blots in the complete period for blotting area, using this The relatively conventional disk filter filter cake moisture of kind mode can reduce 1%-3%；

(2) clip type filter of the invention, intermediate plate width is only 50-200mm, and the distance on width with filtering disk Successively decrease, farthest reduce plastic zone area of the intermediate plate to filter cake, greatly reduce intermediate plate to filtering disk rotational band The resistance come, it ensure that the normal rotation of filtering disk；

(3) clip type filter of the invention, intermediate plate use elastic material, filter cake compression when, elasticity can be produced and kept away Allow, so as to not only prevent the scratch to filter cake, and reduce further the resistance that intermediate plate is brought to filtering disk rotational, protect The normal rotation of filtering disk is demonstrate,proved；

(4) the distance of each intermediate plate distance filtering disc face of clip type filter of the invention can pass through the two of its top and the bottom Nut is adjusted, so as to constantly optimize the working effect of intermediate plate until optimal.

Embodiment

The embodiment of the present invention is further illustrated below in conjunction with the accompanying drawings.

As shown in Figure 1, 2, a kind of clip type disk filter of the invention, including main shaft 3, be fixed on main shaft 3 extremely Few one filtering disk 2 axial arranged along main shaft and slurry tank 1, described filtering disk 2 is made up of polylith filter fan 4, its It is characterised by：Also include the clamping sheet mechanism for being arranged on each filtering disk 2 both sides and the fixation kit for tingle mechanism,

Described clamping sheet mechanism is that specular is arranged on a pair of intermediate plates 5 that each filtering disk blots area, and each intermediate plate 5 is by one Individual length is consistent with the single length of filter fan 4, and width is made up of 50mm-200mm elastic plate, in described each intermediate plate 5 Top is provided with bolt hole A6, the bottom of each intermediate plate be provided with full thread bolt 10, the intermediate plate 5 towards filtering disk 2 one Side is that arcuate structure, the intermediate plate are remote along the distance in the filtering rotation one lateral extent filtering disk 2 of disk 2 face in the direction of the width, The distance that inverse filtering disk 2 rotates lateral extent filtering disc face is near.

Described fixation kit is made up of upper stationary part and lower fixture,

Described upper stationary part is made up of a full wire bolt 8 and two pairs of nuts I 7, and full wire bolt 8 passes through a pair of intermediate plate tops Bolt hole A6, and the top of a pair of intermediate plates 5 is fixedly connected by two pairs of nuts 7 respectively；

Described lower fixture is by two support bars 9 being symmetrically welded on the shell of filter main shaft 3 and two pairs of nuts II 11 Form, the top of each support bar 9 is provided with bolt hole B, and the screw bolt 10 of each intermediate plate bottom passes through bolt hole B and setting Nut II 11 inside and outside support bar 9 is fixedly connected with support bar 9.

The present invention can be further compacted by the intermediate plate of each filtering disk both sides to filter cake, in the water of filter cake Gas is rapidly disappeared and filter cake is carried out compression and lived again by crack before producing, so as to reconstituting a kind of three-phase equilibrium of gas-liquid-solid Avoid the crack of filter cake from producing, ensure that filter cake effectively blots in the complete period for blotting area, it is relatively conventional in this way Disk filter filter cake moisture can reduce 1%-3%.
