Abstract
The utility model discloses a kind of classified filtering device, comprise housing, the top of housing is provided with top cover, top cover is provided with charging aperture, be vertically arranged with multiple filtration net in housing, the filter space being formed and close that joins end to end of every layer of screen pack, and be coaxial filter space; The top of filter space is provided with shaft and paddle, and top cover is provided with agitator, and paddle connects agitator by shaft, and extends downward in filter space; The bottom of each filter space is provided with discharging opening.The utility model overcomes that existing stage filter grading effect is poor, incomplete defect discharged by material; It is simple to operate, saving of work and time, grading effect are good, discharging is convenient.
Description
Technical field
The utility model relates to technical field of chemical, is specially a kind of classified filtering device.
Background technology
In the industrial production, solidliquid mixture to be separated, obtain the chemical products of different-grain diameter, usual needs have come through operations such as super-dry → grinding → screenings after filtration, can cause the loss of material, the volatilization of solvent, the consumption of energy in this course.And energy-saving and emission-reduction, reduction production cost are one of maximized approach of enterprise profit.The particle species wet method of the different-grain diameter in chemical products cannot be classified by fine filter of the prior art, for this reason, Chen Xudong etc. invent a kind of to reduce the classified filtering device (CN 202962068 U) that operation is measure, by " carrying out various grain fineness to fine chemical product to manage; improve product batches on a pipe; the more effectively granular size of the good often kind of specification of classification ", thus realize the wet method classification of the particle species of different-grain diameter.But this classified filtering device also comes with some shortcomings, can not meet and produce actual requirement.First, classified filtering weak effect; In the ordinary course of things, the filtration incipient stage has the particle being less than medium channel (filter screen, filter cloth, filter paper, filter membrane etc.) diameter on a small quantity and is mixed in filtrate through medium, but particle is very fast at medium channel entrance generation arch formation, granule is stopped and forms filter cake in dielectric surface deposition.Now, what really play interception function to particle is filter cake, and filter medium only plays a part to support filter cake.Once filter cake is formed, granule can not pass through medium, and thus classification is incomplete, weak effect.Secondly, material can not be discharged by discharging opening completely, and the material only near discharging opening could be discharged, and can not Self-discharged away from the material of discharging opening.Finally, separation progression can not be increased and decreased as required.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of classified filtering device, overcomes that existing classified filtering device grading effect is poor, the incomplete defect of discharging, and its grading effect is good, discharging convenient.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of classified filtering device, comprise housing, the top of housing is provided with top cover, top cover is provided with charging aperture, be vertically arranged with multiple filtration net in housing, the filter space being formed and close that joins end to end of every layer of screen pack, and be coaxial filter space; The top of filter space is provided with shaft and paddle, and top cover is provided with agitator, and paddle connects agitator by shaft, and extends downward in filter space; The bottom of each filter space is provided with discharging opening.
Described housing is cylindric, and screen pack also encloses cylindric, and the filter space of innermost layer is cylindric, and the cross section of remaining filter space is circular.
Also evacuating valve is provided with bottom the filter space of bosom in described housing, top cover is provided with control pressurer system, better to filter, as regulated the pressure of filter inside by evacuating valve and control pressurer system, become negative pressure state, guarantee the effect of filtering.
The shaft of described filter space is connected to agitator successively, and the top of each filter space is provided with seal cover, and shaft is passed the center of seal cover and sealed by sealing ring.Paddle is driven by agitator and shaft, stirs, prevent the formation of filter cake to the solidliquid mixture in corresponding filter space, meanwhile, after filtration completes, by the motion of paddle, material is transferred to discharging opening from the place away from discharging opening and discharges.
The aperture of the screen pack in described housing reduces from outside to inside gradually; Successively can filter, improve filter effect.
The utility model is owing to adopting said structure, reasonable in design, simple to operate, once can realize classified filtering, saving of work and time, and filtration is effective, and discharging is easy.

Detailed description of the invention
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As Figure 1-Figure 4, a kind of classified filtering device, comprises housing 1, the top of housing 1 is provided with top cover 2, and top cover is provided with charging aperture 10, is vertically arranged with multiple filtration net 3 in housing 1, the filter space being formed and close that joins end to end of every layer of screen pack, and be coaxial filter space; The top of filter space is provided with shaft 5 and paddle 6, and top cover is provided with agitator 4, and paddle 6 connects agitator 4 by shaft 5, and extends downward in filter space; The bottom of each filter space is provided with discharging opening 7.
Described housing 1 is cylindric, and screen pack also encloses cylindric.
Also be provided with evacuating valve 8 bottom the filter space of bosom in described housing, top cover 2 is provided with control pressurer system 12.
The shaft of described filter space is connected to agitator 4 successively, and the top of each filter space is provided with seal cover 9, and shaft is passed the center of seal cover 9 and sealed by sealing ring 11.
The aperture of the screen pack in described housing reduces from outside to inside gradually.
During use, fed in raw material by charging aperture, material enters the outermost layer filter space of housing, filtered by screen pack, strengthen filter effect by paddle simultaneously, the material that particle is larger is discharged from outermost discharging opening, the material that particle is less enters successively in the filter space of internal layer and further filters, until filter completely, filtrate is discharged from the bottom discharge mouth in the space of innermost layer, in filter process, and can by the pressure of control pressurer system regulating system inside, vacuumize, strengthen filter effect.
