Description
Technical field
The utility model relates to a kind of pump housing technical field, particularly relates to a kind of material envelope pump.
Background technology
Material envelope pump is a kind of novel powder pneumatic load transfer device, belongs to low pressure diluted phase transport classification, utilizes the ejector action of high velocity air to carry out conveying powder material, and at equivalent distance 450m, within the scope of hoisting depth 40m, result of use is best.Be widely used in the short-distance and medium-distance conveying of the dry loose powders such as fly ash, alumina powder, dry kiln ash, coke powder, cement powders at present.
Material envelope pump utilizes gas flow jet effect, make air driven soot particle that ash is delivered to grey storehouse, material envelope pump mainly contains four part compositions and is respectively nozzle, cylindrical pump, jet adjuster, bottom carburetion device, energy during material envelope pump work is from two parts: a part is the kinetic energy of blower fan, and another part is the potential energy of stock column.Stock column is high, potential energy is large, pressure is large, operational throughput is corresponding just large, otherwise then little.
Material envelope pump keeps certain controlling level when normally working, when the discharge quantity that gathers dust of electricity in the short time increases the material envelope pump then controlling level that still normally works and naturally raises, it is corresponding just large until system self-equalizing that raising material pressure along with controlling level increases potential energy increase operational throughput, when the discharge quantity that gathers dust of electricity in the short time reduces the material envelope pump then controlling level that still normally works and naturally reduces, along with the reduction of controlling level, material reduces potential energy and reduces, operational throughput is corresponding just little, until system self-equalizing, the necessary condition that material envelope pump normally works to have certain material envelope height, the pressure of bin-level is greater than malleation when working in material envelope pump, isolated by material level pressure handle positive/negative-pressure, the blast of blower fan sees material off, so necessarily there is certain controlling level.Dust exhaustor must be installed in rewinding storehouse, the exhaust air rate of dust exhaustor is greater than the intake of defeated grey blower fan, otherwise, when intake is greater than exhaust air rate, force rewinding storehouse internal pressure to increase, cause system pressure overbalance, the resistance of ducting is large, air intake with upper part, makes material seal pump cisco unity malfunction from material envelope pump anti-channeling to feed bin.
Material envelope pump has been widely used in cement mill finished cement conveying and thermal power plant's ash transfer system now.Investing little, low this of trouble free, maintenance cost compared to traditional powder conveying equipment (storehouse pump, negative pressure transportation) is undisputable fact.But due to its fed distance restriction (equivalent distance 500 meters, actual distance 300 meters), constrain its development under large thermal power plant long distance delivery operating mode, this problem needs study raising further.But be generally speaking a splendid selection in short-distance and medium-distance conveying.
