Abstract
The utility model relates to a vertical and fan-shaped filtering plate of a disc-shaped filtering machine, which improves an original fan-shaped filtering plate and is characterized in that a filtering panel of the fan-shaped filtering plate is a concave curved plate, when the utility model is in a draught and takes off a filtering mass, the filtering mass is easy to drop off and filtering efficiency is raised.
Description
The application belongs to dewatering machine equipment
At present, upright dish vacuum (pressurization) filter that use in chemical industry, metallurgy, building materials, mine etc. (also being upright dish vacuum (pressurization) filter), its general structure and operation principle save as described in " disc type filter " content as the 208th page the 7th in Coal Industry Press in February, 1994 front page technical secondary school planning teaching material " coal preparation machine ".Its filter is in fan-shaped base of frame mouthpiece to be arranged, and the two sides is that surface plate is formed a fan-shaped casing.When filter is worked, be immersed in air pressure decline in the fan-shaped filter inner chamber in the ore pulp, liquid sees through filter cloth and enters filter in the ore pulp, and mineral grain, unloads filter cake fall when fan-shaped filter forwards certain angle to attached to forming filter cake on the filter cloth.
The shortcoming of above-mentioned fan-shaped filter is: the filter face on fan-shaped filter two sides all is the plane, the outer also corresponding one-tenth of its inner surface of the filter cake plane that forms of filter cloth, as when adopting blowing to take off the cake filter cloth and heave, curved surface and planar curvature that filter cloth forms are more or less the same, and filter cloth and filter cake are not easily separated.
The application's purpose is to overcome above-mentioned deficiency, and a kind of fan-shaped filter of vertical disc shape filter of new construction is provided.
The structure of the fan-shaped filter of vertical disc shape filter of new construction is: fan-shaped framework and two concave curved surface shape filters constitute a casing, are connected with a mouthpiece in fan-shaped bottom.
Its good effect is: because fan-shaped filter two sides is a concave curved surface, the loose covering of filter cloth is on it, when filter is worked, its inner surface of filter cake that the filter cloth surface forms will match with the filter plate curved surface, when using the blowing mode to take off cake, filter cloth is blown to be heaved, because the curved surface that filter cloth formed when filter cloth was heaved is opposite with filter cake inner surface curved surface direction, because of in the filter cloth curved surface direction change procedure, an extrusion process is arranged between filter cake again, thereby filter cake and filter cloth are separated, improved filter cake removing rate, big for forming granularity especially, the filter cloth that granularity is low, effect will be more obvious.
Accompanying drawings the application's embodiment.
Fig. 1 is the application's a structural principle schematic diagram, the 1-framework; 2-filter mouthpiece; 3-concave curved surface filtration panels.
As shown in Figure 1, be fixed with mouthpiece (2) in the bottom of fan-shaped framework (1), it is plate or reticular lamina (3) with holes that two sides are fixed with the concave curved surface filter, and they constitute the casing of a band interface or claim the cage body.
When it is contained in when working on the filter hollow shaft, its outer filter cloth bag that is with the degree of tightness appropriateness, when filter plate is in the ore pulp and vacuumizes by mouthpiece, filter cloth will be attached on the concave curved surface filter face, liquid enters the filter inner chamber by filter cloth and drains by mouthpiece, solid particulate matter adheres to filter cloth and forms filter cake outward, the filter cake inner surface is consistent with concave curved surface filter face shape, when cake is taken off in blowing, filter cloth promotes filter cake to be developed to convex surface to straight plane by concave curved surface again, thereby, improved filter cake removing rate because the curved surface direction is opposite and the mutual assembly pressure of filter cake itself very easily comes off filter cake.
Claims (1)
1, the fan-shaped filter of a kind of vertical disc shape filter is characterized in that at the bottom of fan-shaped filter framework mouthpiece being arranged, and the framework two sides are fixed with the concave curved surface filter, constitutes the fan-shaped casing of a band interface.
