  看干砂机的干燥效果是否理想,要看它的位置。关键是设备内部的温度是否能够达到材料所要求的温度,但是这意味着温度越高越好,但是设备内部的温度应该达到。平衡。这涉及到能量守恒定律。这对人们有好处。人们需要保持阴阳平衡来保持健康。这与砂干燥机的干燥原理有一个共同点,就是保持砂干燥机内部的温度平衡。能保证设备的良好运行。
  To see whether the drying effect of the sand dryer is ideal depends on its location. The key is whether the temperature inside the equipment can reach the temperature required by the material, but this means that the higher the temperature, the better, but the temperature inside the equipment should reach. Balance. This involves the law of conservation of energy. It's good for people. People need to keep the balance of yin and yang to keep healthy. This has one thing in common with the drying principle of the sand dryer, which is to keep the temperature balance inside the sand dryer. It can ensure the good operation of the equipment.
  烘砂机的热平衡过程使加热物料的温度趋于稳定。通过求解传热方程,可以得到热平衡状态曲线和达到热平衡所需的时间。热平衡方程解的具体形式将根据传热边界进行调整:2. 材料周界热流强度;3.材料周围界面附近的对流环境。
  The heat balance process of the sand dryer makes the temperature of the heated material tend to be stable. By solving the heat transfer equation, the heat balance state curve and the time needed to reach the heat balance can be obtained. The specific form of the solution of the heat balance equation will be adjusted according to the heat transfer boundary: 2. The heat flow intensity around the material boundary; 3. The convection environment near the interface around the material.
  即使假定干燥器内的物料是均匀的,由于物料界面的散热,温度会低于物料内部的温度,温度会更高,温度梯度会指向内部。此外,这是完全相反的加热材料与传统的热媒。在一般的工程设计中,通常要估计加热材料所需的输入功率。下列结果应与热平衡方程相结合:加热材料所需的热量通常应包括两部分:持续加热和除湿。从理论上讲,如果加热器只用于脱水,那么在20°C的初始温度下,1千瓦的水可以在1小时内转化为1.4公斤的蒸汽。事实上,能量是在加热和脱水过程中损失的,所以每千瓦时热能的脱水率低于这个数字。

  Even if the material in the dryer is assumed to be uniform, due to the heat dissipation of the material interface, the temperature will be lower than the internal temperature of the material, the center temperature will be higher, and the temperature gradient will point to the internal. In addition, it is the opposite of heating materials with traditional heating medium. In general engineering design, the input power required for heating materials is usually estimated. The following results should be combined with the heat balance equation: the heat required to heat a material should generally consist of two parts: continuous heating and dehumidification. Theoretically, if the heater is only used for dehydration, 1 kW of water can be converted into 1.4 kg of steam in 1 hour at an initial temperature of 20 ° C. In fact, energy is lost during heating and dehydration, so the dehydration rate per kilowatt hour of heat energy is lower than this figure.
  干砂机的干燥效果好不好,取决于设备本身的质量,这也离不开技术人员的操作水平。在砂干燥机的运行过程中,达到所需的温度是很重要的。非常相关。我们应该注意设备的内部结构,优化内部结构,使干燥设备更加。
  The drying effect of the sand dryer depends on the quality of the equipment itself, which also depends on the operation level of the technical personnel. In the operation of the sand dryer, it is very important to reach the required temperature. Very relevant. We should pay attention to the internal structure of the equipment, optimize the internal structure, and make the drying equipment more efficient.
