A kind of diaphragm type powder delivery system
The utility model relates to powder delivery system, particularly relates to a kind of diaphragm type powder delivery system.
At petrochemical complex production industry, often can use granular material, and the conveying of granular material can cause dust pollution, therefore granular material adopts closed conveying system usually, avoids the powder in manual operation process to splash, and the dust caused sucks.Current powder delivery system adopts pressure to carry usually, and such delivery system not only feeding is uneven, and easily causes powder delay to cause pipe choking.
Utility model content
The purpose of this utility model is to provide a kind of diaphragm type powder delivery system, causes contamination of raw material, also cause dust pollution in environment simultaneously to overcome powder exposure in powder carry process.
The technical solution of the utility model is: a kind of diaphragm type powder delivery system, is characterized in that: comprise storage bin, membrane pump, reactor, described membrane pump is provided with pump inlet, suction flange, inlet hose, pump discharge, outlet hose, discharge flange, symmetrical cavity, compressed air delivery device, air intlet, exhausr port, exhaust hose, noise silencer, exhaust gas collection case, described storage bin connects inlet hose by suction flange, described inlet hose connects pump inlet, pump discharge is by outlet hose connection outlet flange, described discharge flange coupled reaction still, described symmetrical cavity connects pump inlet and pump discharge by pipeline, described symmetrical cavity is connected by middle chamber, described air intlet and exhausr port are positioned at the upper and lower both sides of middle chamber, described compressed air delivery device comprises storage tank, pressure regulating valve, compression indicator, air filter, ball valve, air hose, air inlet conversion head, pressurized air flows out from storage tank passes through pressure regulating valve successively, compression indicator, air filter, ball valve, air hose, air inlet conversion head, middle chamber is entered through air intlet, in cavity, drive powder to move, discharge through exhausr port, described exhausr port connects noise silencer by exhaust hose, described noise silencer is placed in exhaust gas collection case.
Further, described membrane pump is totally enclosed transport model.
Further, described inlet hose, outlet hose, exhaust hose are sebific duct.
Further, described storage bin, reactor material are corrosion-resistant steel.
Further, described pressure regulating valve, ball valve are check valve.
The beneficial effects of the utility model are: this powder delivery system adopts pneumatic dry powder membrane pump as powder-material conveying equipment, adopts hermetic transport model, directly powder is delivered to reactor from storage bin, decrease the dust pollution of working environment; Pneumatic dry powder membrane pump adopts symmetrical cavity, has stopped the latch up phenomenon of compacting caking in traditional force feed process and generation, has greatly improved transport efficiency; Pneumatic dry powder membrane pump is a Whole Equipment, by flange and other equipment connections of import and export, and convenient mobile and dismounting; Whole delivery system is full-automatic, improves production efficiency, reduces the labour intensity of workman.
