[0025] Specifically, the shape and size of the filter screen 21 match the shape and size of the opening of the quenching tank 10, the filter screen 21 covers the opening of the quenching tank 10 and is movably embedded inside the quenching tank 10, and the filter screen 21 is submerged in the quenching medium in the quenching tank 10. After each quenching of the quenching tank 10 is completed, the residues in the quenching medium can be fished by moving the filter screen 21 upward, and the residues can be transferred and cleaned by detaching the filter screen 21. Thus, the accumulation of residues is avoided, the medium is not polluted, and the cooling capacity and purity of the medium are not affected, so as to ensure the quenching effect of the subsequent castings.
