Description

Technical Field

[0001] The utility model relates to the technical field of lost foam pattern processing, in particular to a drying room for refractory coating of lost foam pattern. Background Technique

[0002] EPS board is the abbreviation of expandable polystyrene board. It is a polystyrene foam plastic board with a closed-cell structure, which is made by heating and pre-foaming expandable polystyrene beads and then heating and molding them in a mold. It is made from raw materials through processes such as pre-expansion, aging, molding, drying, and cutting. It can be made into foam products with different densities and shapes, and can also produce foam boards with various thicknesses. It is widely used in fields such as construction, insulation, packaging, refrigeration, daily necessities, and industrial casting. It can also be used for the manufacture of exhibition venues, product showcases, advertising signs, and toys. To meet the national building energy-saving requirements, it is mainly applied to external wall external insulation, external wall internal insulation, and floor heating of exterior walls. Lost foam casting is a new casting method that uses a foam plastic model for casting. Through the combination of binder-free dry sand and vacuum pumping technology, high-precision and high-quality castings can be produced. Lost foam casting, also known as full-mold casting, is an advanced casting process and is hailed as a "revolution" in the history of casting. It uses a foam plastic model similar in size and shape to the casting. After being dipped in refractory coating and dried, it is vibrated and shaped in dry quartz sand, and poured under negative pressure, causing the model to gasify and the liquid metal to occupy the position of the model, and forming a casting after solidification and cooling. This method does not require mold removal, has no parting surface, and no sand core. Therefore, the casting has no flash, burr, and draft angle, reducing the dimensional error caused by the combination of sand cores. The advantages of lost foam casting include good casting quality, low cost, unlimited material, high dimensional accuracy, smooth surface, few internal defects, and the ability to achieve large-scale and mass production. In addition, it can improve the working environment, reduce labor intensity, and reduce energy consumption, and is hailed as the green casting method in the 21st century. With the development of society, when the refractory coating on the surface of the lost foam pattern needs to be dried, a drying room is used.

[0003] Existing equipment such as CN217615833U, a drying room for foam pattern refractory coating, has a house body, and a heat-insulating door panel is arranged at the front of the house body; several induced draft fans with valves are arranged at the top of the house body, and the induced draft fans introduce outdoor air into the room. Inside the house body, several electric heating tubes are arranged directly below the induced draft fans, and each electric heating tube operates independently; several workpiece storage racks for placing foam pattern workpieces are also arranged inside the house body, and a heat-insulating cover plate is provided at the top of each workpiece storage rack; by self-designing a brand-new structure of the coating workpiece drying room, the utility model can dry a large number of coated workpieces at one time, and the internal temperature can be controlled within a certain range through adjustment, creating convenience for the rapid drying of the overall workpieces, greatly improving the drying efficiency, and having a good drying effect; the whole drying room has good heat preservation and heat insulation effects and a long service life.

[0004] When workers need to dry materials, they place the materials in the drying room so that the drying room can dry the materials. Since a large amount of poisonous gas will be emitted by the materials during the drying process in the drying room, and the poisonous gas will be mixed with the hot air, but the exhaust efficiency of the existing drying room is relatively low, resulting in workers inhaling the residual poisonous gas into their bodies when taking out the materials, which in turn causes problems that the physical health of the workers will be affected.
