The discharging hole of a stirring tank is communicated with the inlet of a feeding pump inlet through a conveying pipe; the outlet of the feeding pump is communicated with the feeding hole of the filter press through a conveying pipe; a filtrate receiver is positioned below a liquid discharging hole of the filter press; the exhaust port of an air storage tank is communicated with a total air conveying pipe through an air conveying pipe and a valve; a plurality of branch air conveying pipes on the total air conveying pipe are communicated with a membrane plate in the filter press respectively; and the inlet of the air storage tank is communicated with the compressed gas outlet of an air compressor through an air conveying pipe. The system and the method have the advantages that: I, a better filtering effect is achieved for the testing system of the pumping pressure coal slime filter press, more accurate data are provided for type selection of the filter press, the production efficiency is increased, and the aim of saving energy is fulfilled; and II, a feeding system is simple and convenient, the filter-pressing speed can be automatically adjusted along with a filtering process by using the feeding pump, the filtering effect is ensured, and diaphragm squeezing equipment is arranged simultaneously; and the system has the advantages of shortening the filtering period and lowering the water content of a filter cake.
Description
Technical field
The present invention relates to a kind of test through pump pressure type coal slime filter press pilot system, can accurately match the pump pressure type coal slime filter press pilot system and the test method of filter press for the coal slime treatment system, coal slime press filtration pilot system is made the field.
Background technology
Existing pump pressure type coal slime filter press 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.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of test, can accurately match the pump pressure type coal slime filter press pilot system and the test method of filter press for the coal slime treatment system through pump pressure type coal slime filter press pilot system.
Design: in order to realize above-mentioned purpose of design.Adopt the direct forced pilot system of feed pump.The purpose of doing like this is: this feed system is simple, convenient, and feed pump can be regulated speed of filter pressing automatically along with filter process, guarantees filter effect.Increase diaphragm pressing equipment simultaneously, have the filter cycle of shortening, reduce the high advantage of filter cake moisture content.
Technical scheme 1: pump pressure type coal slime filter press pilot system; The agitator tank discharging opening is communicated with the feed pump import through conveying pipeline; The feed pump outlet is communicated with the filter press charging aperture through conveying pipeline, and filtrate receiver is positioned at filter press fluid hole below, and the air accumulator exhaust outlet is communicated with total appendix through appendix and valve; Many appendixs on total appendix are communicated with respectively with the membrane filter plate in the filter press, and the air accumulator import exports with the air compressor Compressed Gas through appendix and is communicated with.
Technical scheme 2: coal slime press filtration property test method, through coal slime agitator tank preparation coal slurry, the coal slurry for preparing directly is pressed into the entering filtering equipment through feed pump 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 according to test data; Filter press is carried out suitable type selecting, dispose rational filtration system.
The present invention compares with background technology, and the one, make pump pressure type coal slime filter press 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, feed system is simple, convenient, and feed pump can be regulated speed of filter pressing automatically along with filter process, guarantees filter effect, increases diaphragm pressing equipment simultaneously, has the filter cycle of shortening, reduces the high advantage of filter cake moisture content.
