Description
Technical field
The present invention relates to field of mechanical die, particularly relate to a kind of energy-saving foam pre-expander being accurately controlled.
Background technology
Evaporative pattern foam, is material bead to be first passed through foam pre-expander carry out steam under a certain pressure and send out in advance, then the material bead sent out in advance through steam is filled with in mold cavity, obtain evaporative pattern foam through forming machine molding.In general, the quality of foam pre-expander, function determine the pre-hair quality amount of foam raw material, and the pre-hair quality amount of foam raw material determines the quality of evaporative pattern foam finished product.Existing foam pre-expander, the material bead size issued in advance is uneven, i.e. the uniformity is inadequate；Degree of raw and cooked is uneven, and outward appearance is the most penetrating；Between every tubbing, density is inconsistent, does not reaches the requirement producing evaporative pattern foam.
Summary of the invention
The purpose of the present invention is that the foam pre-expander providing the density of a kind of foam raw material to be accurately controlled, to solve the problems referred to above.
To achieve these goals, the technical solution used in the present invention is such that a kind of foam pre-expander, including the steam chest below charging basket, described charging basket and the hopper that is connected with described charging basket, the height value of described charging basket is 0.5-0.8 with the ratio of the cross-sectional area value of charging basket, steam chest base plate it is provided with between described steam chest and described charging basket, offering groove on described steam chest base plate, described groove, with the geometric center of steam chest base plate as starting point, radially distributes to surrounding.
In order to improve the material bead size issued in advance ripe uneven problem uneven, raw, present inventor is found by substantial amounts of test: use the ratio of suitable charging basket height and floor space, and improve the structure of steam chest base plate, such that it is able to steam arrives each position in charging basket equably.
As preferred technical scheme: be provided with at least two vibration material level sensor installing hole on described charging basket wall, be separately installed with vibration material level sensor in described vibration material level sensor installing hole.
As preferred technical scheme: described charging basket top is charging basket lid, at least one outer wall at described charging basket, charging basket lid and steam chest is provided with heat-insulation layer.The pre-temperature stabilization sent out needed for raw material in can making charging basket, thus make the bead size after pre-and permeability uniform further, heat-insulation layer can also make the condensed water in charging basket substantially reduce, thus reduces the water content of pre-raw material, improves the pre-quality sending out rear beadlet further.
Technical scheme as further preferred: the outer wall at described charging basket, charging basket lid and steam chest is provided with heat-insulation layer, 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, it is ensured that intensity；Groove width on described steam chest base plate is 0.5mm, is spaced apart 10mm between described groove.Such setting can make steam more rapidly and uniformly be arrived in charging basket by steam chest base plate.
As preferred technical scheme: the capacity of described charging basket, in terms of 1m, is provided with four vibration material level sensors on described charging basket wall, lays respectively at the position of 0.1m, 0.31m, 0.45m and 0.651m.Can accurately control the amount of raw material, so that the density between every tubbing keeps consistent, meet pre-of raw material different amounts.
As preferred technical scheme: described hopper is funnel-form, the suitable for reading of described hopper is connected with material storage barrel, and end opening is connected with described charging basket lid, it is provided with dividing plate in described hopper, hopper is divided into two parts by described dividing plate, and a part is feeder, and another part is exhaust portion.
Technical scheme as further preferred:: described dividing plate originates in the end opening of described hopper, and described feeder is provided with a compressed air hose, the charging aperture of this compressed air hose described alignment hopper.
When prefoaming machine feeds, compressed air hose is blown in charging basket, and in preventing charging basket, steam is emerged 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, affect production efficiency and product quality after foaming.
As preferred technical scheme: be horn-like below described steam chest；Such shape, steam enters after steam chest, can quickly, reach in charging basket uniformly through base plate it addition, steam enters the condensed water of generation after steam chest, can discharge rapidly.
As preferred technical scheme: described charging basket lid is horn-like；Its advantage: send out the cold steam after raw material in making charging basket in advance, promptly discharge charging basket.
Additionally, it is preferred that this prefoaming machine uses PLC programmable controller and touch screen, it is achieved raw material is weighed, pan feeding, pre-send out, discharging full-automation produces.
Compared with prior art, it is an advantage of the current invention that: this prefoaming machine can improve production efficiency more than 20%, can save the energy consumption of more than 30% simultaneously, and the foam raw material density issued in advance is accurate, bead size is uniform, penetrating, the uniformity of bead size can reach 99%.Using beadlet that this prefoaming machine sends out in advance as raw material production froth pulp out, casting producer is by normal production technology, and the qualification rate of foundry goods is up to more than 95%.And the beadlet that existing prefoaming machine is sent out in advance is as raw material production froth pulp out, casting producer tries one's best, and uses various means, and the qualification rate of foundry goods also can only achieve about 80%.
