Casting sand processing equipment

Abstract

Provided is casting sand processing equipment that can reduce, for sand processing equipment as a whole, the dimensions and costs of the equipment. The casting sand processing equipment, in which a frame is opened after casting and the casting sand after a cast object is removed is processed, is provided with the following: a hopper (1) which is divided into a first chamber (1a) and a second chamber (1b) by a dividing wall (8); a sand emitting device (2) that is disposed inside of the first chamber (1a), crushes clumps of casting sand which were loaded into the first chamber (1a), and emits the casting sand which was subjected to clump crushing so as to supply the same from an opening (9) provided in the divided wall (8) to the second chamber (1b); an air introduction port (11) and a suction port (10) which are communicably connected to the second chamber (1b); and a first conveyor (12) that is disposed below the second chamber (1b) and conveys the casting sand stored in the second chamber (1b). Due to this configuration, the crushing of clumps of, the cooling of, and the storing of casting sand can be carried out in one piece of equipment.

Description

technical field [0001] The invention relates to molding sand processing equipment. More specifically, it relates to molding sand processing equipment after casting and taking out castings in bins. Background technique [0002] Conventionally, molding sand is molded into a mold, and after casting, it is box splittered to take out the casting and then sand-treated to be reused in the mold (for example, refer to Japanese Patent Application Laid-Open No. 59-229255). If we look at conventional sand processing equipment, there are usually magnetic separators for removing iron flakes, screens for removing sand lumps, sand coolers for cooling sand, hoppers for storing cooled sand, etc. before kneading. Individual functional units are arranged at appropriate intervals in the sequence of steps. [0003] However, in conventional sand processing equipment, sand conveying devices (for example, belt conveyors, bucket elevators, etc.) between monomers with their own functions are also re...

AI Technical Summary

Problems solved by technology

[0003] However, in the conventional sand processing equipment, sand conveying devices (for example, belt conveyors, bucket elevators, etc.) between the monomers with their own functions are also required, so there is a problem that the sand processing equipment as a whole requires a large problem setting volume

In addition, along with this, there is also a problem that equipment costs become high.
