Description
Technical Field
[0001] The utility model belongs to the technical field of casting dust removal, in particular to a lost foam casting dust removal device. Background Art
[0002] When the lost foam is being cast, it will contain magnesia powder, quartz sand and forsterite powder, which are usually the preferred refractory materials for preparing coatings for alkaline steel castings. The main component of magnesia sea powder is the sintered block obtained by calcining natural magnesite (MgCO2) and then crushing, grinding and magnetic separation. Lost foam casting is a new casting method that combines paraffin or foam models with similar size and shape to the casting into a model cluster, brushes on refractory coating and dries it, buries it in dry quartz sand for vibration molding, pours it under negative pressure, vaporizes the model, and the liquid metal occupies the model position, and forms a casting after solidification and cooling.
[0003] In the current prior art, there are various lost foam casting dust removal devices on the market. The existing lost foam casting dust removal devices absorb the dust in the dry quartz sand through a fan during dust removal. When the quartz sand is being guided, the amount of flow at one time is relatively large. The ordinary fan can only clean the dust on the outermost side of the quartz sand, while the internal dust impurities will remain on the surface of the quartz sand. During casting, the dust on the surface of the quartz sand will adhere to the surface of the casting original, so that many small defects will remain on the surface of the product, thereby affecting the working efficiency and working effect of the lost foam casting dust removal device.
[0004] To this end, the utility model provides a lost foam casting dust removal device. Utility Model Content
