Description

Technical Field

[0001] The invention relates to the technical field of casting material separation, in particular to a casting separation and sorting processing line. Background Art

[0002] Cast wear-resistant parts are formed by sand casting, such as wear-resistant casting balls or wear-resistant casting segments; after casting, the sand on the casting needs to be cleaned and the riser needs to be separated; currently, separation drum processing lines are mostly used to separate castings.

[0003] For example, when separating large-sized balls (outer diameter is generally greater than 50mm), the cast castings are directly transported to the rotating separation cylinder, which rotates the cast balls and the risers to impact and separate them without placing medium balls, and then output them for sorting; when separating small-sized micro balls (outer diameter is generally less than 40mm), large-sized medium balls need to be placed in the rotating separation cylinder, and the residual sand on the castings can be efficiently removed by rotating and colliding with the medium balls; different specifications of castings have different separation and processing methods, and multiple processing lines need to be set up for different specifications of castings, which occupies a large space and has low equipment utilization.

[0004] For example, patent CN216729389U discloses a casting material rotary separation cylinder, which includes a material separation cylinder, one end of which is provided with a feeding structure, and the other end of which is provided with a discharging structure, wherein the discharging structure is a conical cavity, the large end of which is connected to the material separation cylinder, and the outer edge of which is provided with a group of discharging ports; the discharging ports are circular holes, the aperture of which is larger than the outer diameter of the casting, and smaller than the outer diameter of the medium ball. The medium ball is placed in the rotary separation cylinder, which cannot be used for the separation and sorting of large-sized cast balls. Summary of the invention

[0015] The line-dividing conversion mechanism is a belt conveyor capable of forward and reverse rotation. The large ball and riser sorting mechanism and the micro ball and medium sorting mechanism are respectively arranged on both sides of the rotating separation drum.
