As further preferred technical scheme: be provided with heat-insulation layer at the outer wall of described charging basket, charging basket lid and steam chest, insulation layer thickness is 50mm.
As preferred technical scheme: described steam chest base plate is corrosion resistant plate, and its back side is provided with reinforcement steel plate, base plate can be made indeformable, proof strength; Groove width on described steam chest base plate is 0.5mm, is spaced apart 10mm between described groove.Arranging like this can make steam arrive in charging basket more fast, uniformly across steam chest base plate.
As preferred technical scheme: the capacity of described charging basket, in 1m3, described charging basket wall is provided with four vibration material level sensors, lays respectively at the position of 0.1m3,0.31m3,0.45m3 and 0.651m3.Accurately can control the amount of raw material, thus the density between every tubbing is consistent, meet the pre-of raw material different amounts and send out.
As preferred technical scheme: described hopper is funnel-form, and the suitable for reading of described hopper is connected with material storage barrel, end opening is connected with described charging basket lid, dividing plate is provided with in described hopper, hopper is divided into two parts by described dividing plate, and a part is feeder, and another part is exhaust portion.
As further preferred technical scheme:: described dividing plate originates in the end opening of described hopper, and described feeder is provided with a compressed air hose, and this compressed air hose described aims at the charging aperture of hopper.
When prefoaming machine charging, compressed air hose is blown in charging basket, prevents hot gas in charging basket from emerging from charging aperture, prevents raw material to be bonded at charging aperture, because if raw material is bonded at charging aperture, can block charging aperture after foaming, affect production efficiency and product quality.
As preferred technical scheme: be horn-like below described steam chest; Such shape, after steam enters steam chest, can fast, evenly reach in charging basket by base plate, in addition, the condensed water that steam produces after entering steam chest, can discharge rapidly.
As preferred technical scheme: described charging basket lid is horn-like; Its advantage: make the cold steam after a pre-raw material in charging basket, promptly discharge charging basket.
In addition, preferably this prefoaming machine adopts PLC programmable controller and touch-screen, realize that raw material is weighed, pan feeding, to send out in advance, discharging full-automation produces.
Compared with prior art, the utility model has the advantage of: this prefoaming machine can enhance productivity more than 20%, the energy consumption of more than 30% can be saved simultaneously, and the foam raw material density sent in advance is accurate, bead size is even, penetrating, the uniformity of bead size can reach 99%.The froth pulp that the bead adopting this prefoaming machine to send out in advance is produced as raw material, casting producer is by normal production technology, and the qualification rate of foundry goods can reach more than 95%.And the froth pulp that the bead that existing prefoaming machine is sent out in advance is produced as raw material, casting producer tries one's best, and use various means, the qualification rate of foundry goods also can only reach about 80%.
