As an embodiment of the present invention, an elastic filter screen 20 is disposed inside the lower discharging tray 56, and the upper end of the elastic filter screen 20 is in pressing contact with the bottom end of the inserting column 6; the outer ring wall of the elastic filter screen 20 is contacted with the vertical side wall of the L-shaped clamping strip 7; when the installation tool works, when an operator needs to install the insertion column 6, the bottom end of the insertion column 6 can be abutted against the upper end of the elastic filter screen 20, so that the elastic filter screen 20 can generate a depression in the material receiving disc 8, and the elastic filter screen 20 can filter small particle slag remaining in the quenching medium filtered by the discharge hole 81 again, so that the utilization rate of the quenching medium is further improved; meanwhile, when an operator needs to clean the slag on the elastic filter screen 20, the bolts arranged on the material receiving disc 8 can be taken down, the elastic filter screen 20 is separated from the extrusion of the insertion columns 6, so that the filter screen under the tower has certain resilience, and then the small particles gathered on the elastic filter screen 20 can be cleaned quickly.

As an embodiment of the present invention, the vertical side wall of the L-shaped engaging strip 7 is engaged with the inner side wall of the receiving tray 8, and the horizontal side wall of the L-shaped engaging strip 7 movably passes through the lower discharging tray 56 and is located outside the lower discharging tray 56; a plurality of arc-shaped bulges 30 are uniformly arranged on the inner side wall of the lower fixed disk 55, and the arc-shaped bulges 30 are uniformly in rotating extrusion contact with the end parts of the horizontal side walls of the L-shaped clamping strips 7; when the lower stripping disc 56 rotates, the plurality of L-shaped clamping strips 7 penetrating through the side wall of the lower stripping disc 56 rotate and extrude the plurality of arc-shaped protrusions 30, so that the L-shaped clamping strips 7 swing, the elastic filter screen 20 clamped on the vertical side wall swings due to the swinging of the L-shaped clamping strips 7, and the swinging of the elastic filter screen 20 can improve the self-efficient filtering of residual particle inclusion slag in the quenching medium; meanwhile, the swinging of the L-shaped clamping strips 7 can drive the material receiving disc 8 to slightly shake, and large-particle oxidized slag collected on the material receiving disc 8 is subjected to shaking filtering operation, so that the phenomenon that a blanking hole is blocked by large-particle slag is prevented; so that the quenching medium falling from the receiving tray 8 can quickly fall into the falling tray; meanwhile, the quenching workpiece inserted and fixed on the insertion column 6 can slightly shake in the induction heating ring 2 due to the swinging of the take-up reel 8, so that the induction heating ring 2 can generate disturbance quenching on the surface of the quenching workpiece to further improve the quenching effect of the workpiece; meanwhile, the swinging of the take-up pan 8 can not cause the workpiece to impact the inner wall of the inductance heating ring 2 when swinging, so that the safe use of the inductance heating ring 2 is influenced.
