Abstract
The invention provides a solid-liquid separator which is high in filtration efficiency. The solid-liquid separator comprises a container, wherein a filtration plate is arranged in the container and divides an inner cavity of the container into an upper cavity and a lower cavity; and a piece of filtration cloth or a filtration net covers the lower surface of the filtration plate. The solid-liquid separator also comprises an inlet for inputting filtration slurry into the lower cavity, an outlet for discharging the slurry above a filtration cake, an outlet for discharging media above the filtration plate and an openable orifice convenient for removing the filtration cake from the lower cavity; the inlet for inputting the slurry into the lower cavity is positioned above the filtration cake; and the inlet for inputting the slurry into the lower cavity, the outlet for discharging the slurry above the filtration cake and the outlet for discharging media above the filtration plate are controlled by corresponding valves. The slurry is filtered by the filtration net or the filtration cloth, and filtration slag can be naturally deposited, so that the filtration cake is formed in the lower cavity; and the slurry cannot be accumulated on the filtration cloth or the filtration net, so that the filtration efficiency is high.
Description
Technical field
The present invention relates to filtration art, be specifically related to solid-liquid separator.
Background technology
The filter type of existing solid-liquid separator is: filter pulp is added on the filter cloth, and filter residue is stayed and is formed filter cake on the filter cloth, stops up the space of filter cloth, and filtrate need be passed filter cake, so along with the carrying out of filtering, filter efficiency declines to a great extent.Filter cloth stops up easily, and service life is short, changes filter cloth cost height.
Summary of the invention
The technical problem to be solved in the present invention provides the high solid-liquid separator of a kind of filter efficiency.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of solid-liquid separator, comprise container, filter plate is set in the container, filter plate is divided into epicoele and cavity of resorption with container intracavity, the filter plate lower surface covers filter cloth or filter screen, this solid-liquid separator also comprise with filter pulp import import in the cavity of resorption, outlet that filter cake is discharged with sizing liquor, the outlet that filter plate top medium is discharged and the able to turn on or off aperture that makes things convenient for the cavity of resorption filter cake to shift out, the import that filter pulp is imported in the cavity of resorption is positioned at the filter cake top; With filter pulp import import in the cavity of resorption, outlet that filter cake is discharged with sizing liquor and the outlet that filter plate top medium is discharged controlled by corresponding valve.
Above-mentioned solid-liquid separator, the outlet that filter plate top medium is discharged comprises the outlet that filter plate top supernatant is discharged; The outlet that filter plate top supernatant is discharged is controlled by valve.
Above-mentioned solid-liquid separator, the outlet that filter plate top medium is discharged also comprises the outlet that the above medium of filter plate is discharged, and the outlet of the above medium discharge of filter plate is positioned at the below of the outlet that filter plate top supernatant is discharged; The outlet that the above medium of filter plate is discharged is controlled by valve.
Above-mentioned solid-liquid separator, the import that filter pulp is imported in the cavity of resorption is provided by filter pulp distributing pipe or filter pulp distributor that filter pulp is disperseed to import in the cavity of resorption.
Above-mentioned solid-liquid separator, the slurries of discharging via the outlet that filter cake is discharged with sizing liquor enter cavity of resorption once more by pipeline.
Filter pulp is filtered through the filter screen or the filter cloth of top, and the filter residue natural subsidence forms filter cake in cavity of resorption, be not deposited on filter cloth or the filter screen filter efficiency height.Filter plate top medium (filtrate) is discharged by outlet, when filter cake arrives the outlet that filter cake is discharged with sizing liquor, opens this outlet, and filter cake is discharged with sizing liquor, then, filter cake is shifted out by the aperture, filters then next time.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the present invention:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, solid-liquid separator comprises container, and filter plate 1 is set in the container, and filter plate is divided into epicoele 2 and cavity of resorption 3 with container intracavity, and the filter plate lower surface covers filter cloth or filter screen 4.This solid-liquid separator also comprises the outlet 6 of discharging with sizing liquor with the import 5 in the filter pulp to be filtered input cavity of resorption, with filter cake, the outlet that filter plate top medium is discharged and the able to turn on or off aperture 7 that makes things convenient for the cavity of resorption filter cake to shift out.The import that filter pulp is imported in the cavity of resorption is positioned at the filter cake top.With filter pulp import import in the cavity of resorption, outlet that filter cake is discharged with sizing liquor and outlet that filter plate top medium is discharged be by corresponding valve 8 controls.
Filter pulp to be filtered is input in the cavity of resorption via import 5, and filter pulp is filtered and natural subsidence through the filter screen or the filter cloth of top, forms filter cake in cavity of resorption, and filtrate is discharged via the outlet that filter plate top medium is discharged; When the filter cake height reaches outlet 6 the time, stop filter pulp and be input to cavity of resorption, by outlet 6 filter cake is discharged with sizing liquor, after filter cake drains with sizing liquor, the cavity of resorption filter cake is shifted out by aperture 7; Then filter pulp to be filtered is input in the cavity of resorption via import 5, proceeds to filter.
For some filter pulp, in filter process, layering will appear, be respectively from top to bottom: low filtrate layers, the supernatant layer of solids content of the slurry layer that the solids content between cake layer, filter cake and the filter plate is high, filter plate top.In supernatant layer outlet 9 is set, filter plate top supernatant is discharged.
The outlet that filter plate top medium is discharged also comprises the outlet 10 that the above medium of filter plate is discharged, and outlet 10 is near the filter plate setting, and outlet 10 is positioned at the below of the outlet that filter plate top supernatant is discharged.The outlet that the above medium of filter plate is discharged is controlled by valve.When the filter cake height reaches outlet 6 the time, stop filter pulp and be input to cavity of resorption, earlier by the outlet 10 filtrate layers output that the solids content of filter plate top is low, and then by exporting the 6 slurry layer discharges that the solids content between filter cake and the filter plate is high, after filter cake drains with sizing liquor, the cavity of resorption filter cake is shifted out by aperture 7.
The import that filter pulp is imported in the cavity of resorption is provided by filter pulp distributing pipe 11 or filter pulp distributor that filter pulp is disperseed to import in the cavity of resorption, and the input of filter pulp multiple spot is little to the slip stirring, and is faint to the impact of below filter cake, good filtration effect.
The slurries of discharging via the outlet 6 that filter cake is discharged with sizing liquor enter cavity of resorption once more by pipeline, and this part slurries is filtered once more.
