A discharging port of an agitation tank is communicated with an inlet of a material storage tank through a material conveying pipe, an outlet of the material storage tank is communicated with a feeding port of the filter press through a material conveying pipe, a filtrate trough is located below a liquid outlet hole of the filter press, an air outlet of an air storage tank is communicated with the material storage tank through an air conveying pipe and a valve and communicated with the filter press through a main air conveying pipe, a plurality of branch air conveying pipes positioned on the main air conveying pipe are communicated with diaphragm filter plates in the filter press respectively, and an inlet of the air storage tank is communicated with a compressed gas outlet of an air compressor through an air conveying pipe. The coal slime filter-press testing system has the advantages that the coal slime filter-press testing system achieves good filtering effect, precise data are provided for filter press type selection, and the aims of improving production efficiency and saving energy are achieved; and high-pressure compression mediums are utilized, drum film pressing is adopted to further dehydrate filtered filter cake, the filter cycle is shortened, moisture content of the filter cake is reduced, and the thickness of the filter cake can be adjusted according to actual demand.
Description
Technical field
The utility model relates to a kind of test through coal slime press filtration property pilot system, can accurately match the coal slime press filtration property pilot system of filter press for the coal slime treatment system, and coal slime press filtration pilot system is made the field.
Background technology
Existing coal slime press filtration property pilot system adopts pressure air pan feeding formula pilot system, and filtering equipment directly carries out determination of moisture after filtering.Because system work process is constant pressure filtration, and there is certain influence in the press filtration effect, there is not diaphragm pressing equipment that filter cake is carried out the barrier film extruding after the filtration again, can not give full play to the filtration advantage of coal slime filter press.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of test, can accurately match the coal slime press filtration property pilot system of filter press for the coal slime treatment system through coal slime press filtration property pilot system.
Design: in order to realize above-mentioned purpose of design.Increasing diaphragm pressing equipment in the pressure air pan feeding formula pilot system, is the major technique characteristic of the utility model.The purpose of doing like this is: utilize the high pressure compressed medium, adopt the eardrum squeezing, the filter cake after filtering is carried out the more dehydration of deep layer, have the filter cycle of shortening, reduce the high advantage of filter cake moisture content, also can regulate filter cake thickness according to actual needs.
Technical scheme: coal slime press filtration property pilot system; The agitator tank discharging opening is communicated with the storage tank import through conveying pipeline; The storage tank outlet is communicated with the filter press charging aperture through conveying pipeline; Filtrate receiver is positioned at filter press fluid hole below; The air accumulator exhaust outlet is through appendix and valve one tunnel is communicated with storage tank, another road be communicated with through total appendix, always many on the appendix prop up appendix and are communicated with respectively with membrane filter plate in the filter press, the air accumulator import is passed through appendix and is exported with the air compressor Compressed Gas and be communicated with.
The utility model is compared with background technology, and the one, make coal slime press filtration property pilot system obtain better filter effect, for the filter press type selecting provides more precise information, reach and enhance productivity, the purpose of energy savings; The 2nd, utilize the high pressure compressed medium, adopt the eardrum squeezing, the filter cake after filtering is carried out the more dehydration of deep layer, have the filter cycle of shortening, reduce the high advantage of filter cake moisture content, also can regulate filter cake thickness according to actual needs.
Description of drawings
Fig. 1 is a coal slime press filtration property pilot system sketch map.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Coal slime press filtration property pilot system; Agitator tank 1 discharging opening is communicated with storage tank 2 imports through conveying pipeline; Storage tank 2 outlets are communicated with filter press 8 charging apertures through conveying pipeline; Filtrate receiver 9 is positioned at filter press 8 fluid holes below; Air accumulator 3 exhaust outlets are through appendix and valve one tunnel is communicated with storage tank 2, another road be communicated with through total appendix 7, always many on the appendix 7 prop up appendix and are communicated with respectively with membrane filter plate in the filter press 8, air accumulator 3 imports are passed through appendix and are exported with air compressor 6 Compressed Gas and be communicated with.Said air accumulator 3 is provided with automatic pressure regulator 4 and Pressure gauge 5.Said filter press 8 is a diaphragm filter press.
Among Fig. 1, agitator tank 1 is the coal slime mixing plant, as requested concentration preparation coal slurry sample.Material-storage jar 2 is coal slime stock device, stores the coal slurry sample for preparing, and is a kind of pressure vessel, and the pressure display instrument is housed.Air accumulator 3 is provided with automatic pressure regulator 4, Pressure gauge 5, and form native system air compression devices with air compressor 6.For filter press 8 are crucial filtering equipments of native system.Squeezing system 7 (total appendix) is the supporting diaphragm pressing equipment of filter press.Filtrate receiver 9 is used for collecting the filtrating that pressure-filtering process produces.Its coal slime press filtration property test method: through coal slime mixing plant preparation coal slurry, coal slurry is put into stock device, through compressed air unit coal slurry is pressed into filtering equipment from stock device and filters; Adopt diaphragm pressing equipment that filter cake is carried out the barrier film extruding, at last filter cake is carried out determination of moisture, collect data; And to collected data; And, filter press is carried out suitable type selecting according to test data, dispose rational filtration system.Putting into storage tank 2 after promptly in agitator tank 1, having prepared coal slurry stores; Utilize air accumulator 3 to insert compressed air and advance storage tank 2 with air compressor 6; Coal slurry in the storage tank 2 is pressed into filter press 8 filters, squeeze system 7 subsequently and utilize air accumulator 3 and air compressor 6 compressed air to carry out squeeze and filter once more.Filtrating is collected in the filtrate receiver 9, carries out determination of moisture and analysis after filter cake takes out, compiling data, to do type selecting subsequent use.-M-M-coal slime waterline;-K-K-air line.
What need understand is: though the foregoing description is to the mentality of designing of the utility model detailed text description of contrasting; But these text descriptions; Just the simple text of the utility model mentality of designing is described; Rather than to the restriction of the mentality of designing of the utility model, any combination, increase or modification that does not exceed in the utility model mentality of designing scope all falls in the protection domain of the utility model.
