(4) because the arranged outside of described platform has the dash edge, therefore can keep a certain amount of water coolant at every layer of platform, the cooling water inflow of bottom rotating cylinder is increased, take away the heat that the bottom rotating cylinder transmits from body of heater, and slow down the flow velocity of water coolant, thereby further improved the refrigerative effect;
(5) because the bottom on described dash edge is provided with porosely, and therefore the eliminating of surplus water is more convenient, thus make safeguard more convenient;
(6) rotating cylinder is in place because described dash along being split type, therefore is convenient to down;
(7) owing to be provided with sealing between each split, described dash is along being provided with sealing with the described bonding surface of rotating cylinder down, so water can not drain to body of heater, improved the reliability of cooling system work;
(8) because the bottom of described rotation water tank is fixed with water wall, described water wall forms the water channel that is communicated with described rotation water tank with the described rotating cylinder of going up, and therefore can realize the cooling to last rotating cylinder, thereby further improve the refrigerative effect;
(9) because described water wall undulate surrounds the described rotating cylinder of going up, therefore increased cooling area, thereby further improved the refrigerative effect last rotating cylinder;
(10) because the gudgeon installation place of described down rotating cylinder is provided with the gudgeon water retaining cover, so water coolant can not pour into gudgeon and corrode component, thereby further improved the reliability of cooling system work;
(11) because the inner ring riser of described fixedly water tank is inserted in the outer ring, lower edge of described bottom rotating cylinder and apart between the lower edge inner ring on the nearest dash edge of described fixedly water tank, and be provided with certain slit, therefore for having prevented the water coolant body of heater that bleeds, and also guaranteed the normal rotation of time rotating cylinder, thereby further improved the reliability of cooling system work;
(12) because described rotating cylinder down is provided with dividing plate, has therefore improved the intensity of time rotating cylinder, thereby further improved the working life of cooling system.
In a word, water-cooling system good cooling results involved in the present invention, convenient for installation and maintenance, long service life, and can be used for the distributor of various iron-smelting furnace engineering.
