Industrial equipment

Abstract

An industrial equipment includes a cavity configured to store a coolant, and a cooling acceleration device which is accommodated in the cavity and is put in the coolant stored in the cavity. The cooling acceleration device includes a passage formation portion in which a tubular passage extending in a horizontal direction is formed, and an introduction portion configured to introduce molten material dropped into the cavity to the passage formation portion.

What is claimed is: 
     
         1 . An industrial equipment, comprising:
 a cavity configured to store a coolant; and   a cooling acceleration device which is accommodated in the cavity and is put in the coolant stored in the cavity,   wherein the cooling acceleration device includes:
 a passage formation portion in which a tubular passage extending in a horizontal direction is formed; and 
 an introduction portion configured to introduce molten material dropped into the cavity to the passage formation portion. 
   
     
     
         2 . The industrial equipment according to  claim 1 , further comprising a vessel configured to drop drops of molten material,
 wherein the cavity is positioned below the vessel,   the cooling acceleration device is accommodated in the cavity and is below the vessel, and   the molten material dropped from the vessel into the cavity is introduced to the passage formation portion via the introduction portion.   
     
     
         3 . The industrial equipment according to  claim 1 , wherein a cross-sectional area of the passage formation portion, is perpendicular to a bottom surface of the passage formation portion, is 2000 mm 2  or more and 20000 mm 2  or less. 
     
     
         4 . The industrial equipment according to  claim 1 , wherein, in a cross section of the passage formation portion perpendicular to an extending direction thereof, a horizontal length of the cross section is 1 to 200 times a vertical length of the cross section. 
     
     
         5 . The industrial equipment according to  claim 2 , wherein the introduction portion is a through hole formed in a side wall of the passage formation portion facing the vessel. 
     
     
         6 . The industrial equipment according to  claim 5 , wherein a plurality of the through holes are formed so as to be aligned in the extending direction of the passage formation portion. 
     
     
         7 . The industrial equipment according to  claim 1 , wherein a plurality of passage formation portions are installed in the industrial equipment so as to be aligned side by side in a width direction thereof. 
     
     
         8 . The industrial equipment according to  claim 1 , wherein the plurality of passage formation portions are stacked in the vertical direction. 
     
     
         9 . The industrial equipment according to  claim 1 , wherein a ceiling portion of the passage formation portion is provided with a plurality of protrusions formed inside the passage formation portion. 
     
     
         10 . The industrial equipment according to  claim 1 , wherein a floor portion of the passage formation portion is provided with a protrusion formed inside the passage formation portion. 
     
     
         11 . The industrial equipment according to  claim 1 , wherein a covering member is installed on a top of the passage formation portion existing at the highest position in the vertical direction. 
     
     
         12 . The industrial equipment according to  claim 1 , wherein a protruding portion is formed on a top of the passage formation portion at the highest position in the vertical direction.
