用途 Use：
主要用于自硬砂的温度调节。
It is mainly used for temperature adjustment of self hardening sand.
特点 Characteristic：
● 砂子入口与散热管之间设有筛网，防止杂物进入热交换器。
A sieve net is arranged between the sａnd inlet and the radiating tube to prevent sundries from entering the heat exchanger.
● 采用错排散热管的热交换形式，使砂子在曲折的下行过程中不断改变位置，保证砂子充分散热。
The heat exchange from of staggered heat pipe is adopted to make the sａnd change its position continuously in the course of zigzag downstream, so that the sａnd can be fully dissipated.
● 设计较慢的下行速度，砂子自上而下缓慢移动，不但有利于热交换，而且对散热磨损小，延长使用寿命。The design of a slower downward speed, sａnd moving slowly from. up to. down, not only conducive to heat exchange, but also to reduce heat dissipation wear and prolong service life.
● 采用逆流式的热交换形式，水流方向为下进上出，与砂流方向相反。
In the form of countercurrent heat exchange, the direction of flow is downward and upward, which is opposite to the direction of sａnd flow.
● 散热管带高频连续环焊翅片，热交换面积大，热传导效果好。The radiating tube has high frequency continuous ring welding fins, and the heat exchange area is large, and the heat conduction effect is good.
● 配置温控系统全自动操作，当出砂温度超过设定温度时，自动关闭出砂闸门，并启动水循环系统。Configuration temperature control system fully automatic operation, when the sａnd temperature exceeds the set temperature, automatically close the sａnd gate, and start the water circulation system.
● 配有料位检测控制装置，保持砂温调节器内部的热交换器始终被砂子埋住。
Equipped with material level detection and control device to keep the heat exchanger inside the sａnd temperature regulator always buried by sand.
