Energy-saving and environment-friendly drying equipment for processing castings

Abstract

The invention discloses energy-saving and environment-friendly drying equipment for processing castings. The drying equipment comprises a shell, supporting legs, a feed inlet, a discharge port and a conveyor belt. Two partition plates in vertical direction are fixed in the shell to divide the shell into a blowing cavity, a heating and drying cavity and a sweeping cavity; the lower ends of the partition plates above the conveyor belt are fixedly connected to sealing mechanisms; each sealing mechanism comprises a plurality of sealing rubber plates arranged horizontally, magnetic strips fixed totwo sides of each sealing rubber plate and a balancing weight fixed to the lower end of the sealing rubber plate. By feeding the castings successively through different cavities to blow, dry and pavethe castings, so that water on the surfaces of the castings is separated and the castings are dried, and therefore the water removal efficiency is improved; the inner and outer sides of the heating and drying cavity are isolated through the freely opened and sealed sealing rubber plates, so that loss of heat in the heating and drying cavity is reduced. Meanwhile, inside hot air can flow circularly, so that the energy waste is reduced.

Description

technical field [0001] The invention relates to the field of casting processing, in particular to an energy-saving and environment-friendly drying equipment for casting processing. Background technique [0002] At present, in the field of casting, steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. For the castings cleaned after sand casting, the existence of surface moisture is not conducive to the long-term preservation of the castings, and it is easy to cause rusting of the castings. Therefore, it is necessary to dry the castings and dry the cleaning water on the surface; and the common castings In the drying process, a large number of castings are transport...

Problems solved by technology

For the castings cleaned after sand casting, the existence of surface moisture is not conducive to the long-term preservation of the castings, and it is easy to cause rusting of the castings. Therefore, it is necessary to dry the castings and dry the cleaning water on the surface; and the common castings The drying process is to transport a large number of castings into the drying furnace one by one, and then take them out manually after drying all the castings. Continuous operation cannot be performed, resulting in waste of resources
