Abstract
The utility model discloses a kind of stage filter, comprise upper cover and base, between upper cover and base, be provided with the many groups of filtering cabins stacked gradually, described filtering cabin comprises housing, be provided with agitating device in the middle of housing, bottom is provided with screen pack, and the side of lower housing portion is provided with discharging opening.The utility model can increase or reduce over the number of filter position as required, thus realizes the increase and decrease being separated progression, stirs, prevent the formation of filter cake, and can be discharged by discharging opening by the material of filtration in time while filtration; Its reasonable in design, simple to operate, saving of work and time.
Description
Technical field
The utility model relates to technical field of chemical, is specially a kind of stage filter.
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 stage filter (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 stage filter 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 stage filter, overcome existing stage filter grading effect poor, can not increase and decrease and be separated progression, the incomplete defect of discharging, its grading effect is good, progression changeable, discharging are convenient.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of stage filter, comprise upper cover and base, the many groups of filtering cabins stacked gradually are provided with between upper cover and base, described filtering cabin comprises housing, be provided with agitating device in the middle of housing, bottom is provided with screen pack, and the side of lower housing portion is provided with discharging opening; Also be provided with agitator in upper cover, agitator is connected with agitating device.
Described upper cover, between filtering cabin and base, sealing ring is installed, guarantees the sealing completely of whole system, Leakage prevention.
Cover on described and be provided with charging aperture; Material can directly be added by charging aperture, easy to operate.
Described upper cover is also connected with control pressurer system; By control pressurer system, can vacuumize this filter.
Described base is provided with evacuating valve and filtrate (liquid.
Screen pack is from top to bottom installed according to aperture order from big to small.
Described agitating device comprises shaft and paddle, shaft is through the center of screen pack, shaft between the filtering cabin of superposition can be connected together as a whole structure being connected with the mixer of upper cover mutually, is also provided with wear-resistant seal circle and seals between shaft and screen pack.The blade of described paddle is arc, when rotating, material can be moved to the shell rim of filtering cabin, paddle is driven by mixer and shaft, solidliquid mixture is stirred, prevent the formation of filter cake, meanwhile, after filtration completes, by the motion of paddle, material is transferred to discharging opening from the place away from discharging opening and discharge.
The utility model is owing to adopting said structure design, can increase or reduce over the number of filter position as required, thus realize the increase and decrease being separated progression, stir while filtration, prevent the formation of filter cake, and can in time the material of filtration be discharged by discharging opening.Its reasonable in design, simple to operate, saving of work and time, grading effect are good, progression changeable, discharging are convenient.
Accompanying drawing explanation
Fig. 1 is detonation configuration schematic diagram of the present utility model.
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 shown in Figure 1, a kind of stage filter, comprise upper cover 1 and base 2, be provided with the many groups of filtering cabins stacked gradually 3 between upper cover 1 and base 2, described filtering cabin 3 comprises housing 31, is provided with agitating device 32 in the middle of housing 31, bottom is provided with screen pack 33, the side of housing 31 bottom is provided with discharging opening 34, is also provided with agitator 13 in upper cover 1, and agitator 13 is connected with agitating device 32.
Described upper cover 1, between filtering cabin 3 and base 2, sealing ring 4 is installed.
Described upper cover 1 is provided with charging aperture 11.
Described upper cover 1 is also connected with control pressurer system 12.
Described base 2 is provided with evacuating valve 21 and filtrate (liquid 22.
Screen pack 33 is from top to bottom installed according to aperture order from big to small.
During use, fed in raw material by charging aperture 11, material is after filter position successively filters, and the material that particle is larger is discharged from the discharging opening on upper strata, and the material that particle is less enters successively in the filtering cabin of lower floor and further filters, until filter completely, filtrate is discharged from the filtrate (liquid of base, in filter process, and can by the pressure of control pressurer system regulating system inside, vacuumize, strengthen filter effect.
