Description
The utility model relates to a kind of filter that is used for Separation of Solid and Liquid.
Solid-liquid separating method is a lot, has sedimentation to concentrate vacuum filtration, methods such as pressure filtration.In the last few years, a kind of solid-liquid separating method that flow filtration concentrates mode that is referred to as has appearred, this method is to make suspension flow at high speed on the direction parallel with filtering surface, liquid in the suspension sees through filter medium and divides the high filtrate that becomes with suspended particles, and suspended particles are owing to be subjected to the cleaning effect of flow at high speed liquid, can be at the filter medium surface deposition, along with the carrying out of flowing, suspension is concentrated gradually.An advantage of this method is not form filter cake (or only forming very thin filter cake) on the filter medium surface, has reduced the resistance of process, has improved treating capacity; Another advantage is can realize working continuously.Make suspension produce swiftly flowing method and mainly contain the mechanical agitation method, can more easily control the flowing velocity of suspension by mechanical means.Adopt this method to realize that the capital equipment that filters has vane filter press (rotary filter press) (other volume chemical industry (Japanese) Vol.35, No5,1992, P.318-322), cone type continuous filtration filter press (ZL9423913.2) etc., the feature of preceding a kind of equipment is easily to control cocnentration factor, the cleaning efficiency height, but because its design feature is a single-shaft configuration, filter separates with agitating plate, and filter is fixed, and agitating plate is movable, and the major defect of this structure is a complex structure, the installation and maintenance inconvenience, filter medium is changed difficulty, in addition, and at high material inlet far away place, work as progression for a long time especially, because path length causes the pressure loss big, the motive force of filtration is big inadequately; A kind of device structure in back is simple, again can continuous operation, but because filter area only be the surface of a cone, filter area is big inadequately, thereby has influence on treating capacity.
In order to control filter cake thickness effectively, reduce filtration resistance, solve the processing of sad filter materials such as " thin, mud, sticking ", the special the utility model that proposes.
The utility model is to realize like this.The utility model comprises the closed box body type case, shell comprises cover plate and front and rear cover plate up and down, cover plate has two quill shafts that are arranged parallel to each other about passing shell, adopt packing box seal between cover plate and the quill shaft up and down, two quill shafts are fixed on the bearing block, drive by motor, equidirectional with the speed rotation.On two quill shafts that are arranged parallel to each other, circular filtering table is installed, circular filtering table overlaps mutually, circular filtering table comprises filter and scraper plate, the top of filtering table is filter, filter is split type, its filter cloth is installed on 6～12 detachable filters, and the filtering table bottom is the vane type scraper plate.Filtrate is discharged by the filtrate outlet through quill shaft by filter again, and upper cover plate is provided with the material liquid charging aperture, and lower cover is provided with the filter cake outlet.Front and rear cover plate is a detachable, and keeps better elastic to contact with filtering table, to prevent the material liquid short circuit.Spacing between the filtering table that overlaps on the diaxon is controlled at 1～2mm, and to reach the purpose of thin cake filtration, the quantity of filtering table is generally 6～40 on the quill shaft, and the diameter of filtering table is generally 0.4～2m, to guarantee that specified filter area is at 2～60m
2Scope.The rotating speed of the equidirectional rotation of two quill shafts is 5～50rpm.Appropriate location on front and rear cover plate is provided with a plurality of high-pressure water pipe installing ports, is used to assemble high-pressure water pipe, carries out multistage laundry operation.At the filtrate outlet, the vacuum filtration device is set, make pressure filtration and vacuum filtration parallel work-flow become possibility, improve the motive force of filter process, reduce the water content of filter cake.After long period work, filter cloth water permeability variation can feed water under high pressure at the filtrate outlet, carries out back flush, and the water permeability of filter cloth is restored.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1. the utility model cross-sectional view;
Fig. 2. the utility model vertical view;
Fig. 3. the utility model filtering surface structural representation;
Fig. 4. the utility model blade structure schematic diagram.
Its course of work is as follows:
Material liquid feeds by being positioned at upper end cover charging aperture 2 high pressure, two parallel quill shafts 1 rotate with speed under motor drives in the same way, because the 1. dialer in the filtering table is not with filter, material liquid can flow to 2. number filtering table, liquid is discharged at filtrate outlet 7 through quill shaft 1 by the filter 4 on 2. number filtering table top becomes filtrate, 2. the filter cake (or concentrate) of number filtering table top formation is subjected to the 1. scraper plate effect of number filtering table and the pressure effect of feeding liquid, make filter cake (or concentrate) to 3. number filtering table transmission, and 3. be filtered on number filtering table, 3. the filter cake (or concentrate) on number filtering table is subjected to 2. scraper plate 3 effects of number filtering table and the pressure effect of feeding liquid again, make filter cake (or concentrate) to 4. number filtering table transmission, by that analogy.The suspended solid material constantly is transported on each different filtering table by transmission, is subjected to multistage filtering, makes material liquid obtain multistage enrichment.At last, the filter cake behind the multistage filtering is discharged continuously from the filter cake outlet 6 on the bottom end cover.High-pressure water pipe installing port 8 places before and after being positioned on the two waist female cap plates load onto high-pressure water pipe, feed water under high pressure, can carry out multistage laundry operation, make to wash and filter and can finish in same equipment.
The utility model has increased the motive force of filtering owing to adopt vacuum filtration and pressurization feeding while mode of operation; By the gap between control scraper plate and the filter plate, realized thin cake filtration, reduced the resistance that filters filter cake; Take the polydisc frame mode, make its unit volume have bigger filter area, and realized continuous production; Because the utility model is provided with the high-pressure water pipe installing port, makes and filter and wash and in same device, to finish; The utility model adopts the back flush mode that the water permeability of filter cloth is restored; Have advantages such as simple structure, smooth operation, filtering rate height, clean result be good.
Use the utility model filter paper pulp, bentonite slip, calcium carbonate slip.Wherein, two quill shafts are Φ 130 * 25mm, and the quill shaft rotating speed is 8rpm, and the filtering table diameter is 800mm, and filtering table quantity is 10 * 2, and filter result is as shown in table 1: the key technical indexes that table 1. uses the utility model to filter several materials:
| Material | Material liquid wt% | Filter cake wt% | Amount of filtrate kg/m 2.h | Operating pressure MPa |
| Paper pulp | 2 | 12 | 800 | 0.2 |
| The bentonite slip | 5 | 49 | 480 | 0.2 |
| The calcium carbonate slip | 8 | 65 | 900 | 0.2 |
