  干砂机是一种能处理大量物料的干砂机。操作可靠、灵活性大、适应性强、加工能力强,广泛应用于建材、冶金、食品、化工、煤炭、医药、矿产等行业。砂干燥机是一种滚筒干燥机。一般适用于颗粒状物料,也可用于部分进入物料的干法粘稠膏料或含水量高的物料。采用东方品牌的干砂机来体现效果极佳。连续、稳定、自动计量、定量送料是稳定干燥机热力系统,提高熟料产量和质量,降低能耗,保证干燥机安全稳定运行的关键因素之一。
  Dry sand machine is a kind of dry sand machine which can deal with a large number of materials. It is widely used in building materials, metallurgy, food, chemical industry, coal, medicine, mineral industry, etc. Sand dryer is a kind of drum dryer. Generally applicable to granular materials, but also can be used for partially into the material of dry viscous paste or high moisture content materials. The use of Oriental brand dry sand machine to reflect the effect is excellent. Continuous, stable, automatic metering and quantitative feeding is one of the key factors to stabilize the thermal system of the dryer, improve the output and quality of clinker, reduce energy consumption and ensure the safe and stable operation of the dryer.
  随着水泥工业技术的发展,生产过程自动化程度的提高和企业经济技术管理水平的提高,原料粉体进窑计量和定量进窑控制越来越受到重视。由于原料粉和煤粉的细度高、密度小、易粉尘、自流性好,且随着其状态、压力、水分、充气情况的变化很大,给砂干燥机计量和定量进料控制带来了更多的困难。另一方面,各水泥厂的生产方式、规模、设备等条件不同。因此,曲线计量送料装置的使用也是多种多样的。目前,国内外常用的砂干燥机有扬料定量进料(皮带秤)、群料流量计、气举泵定量进料装置、失重进料秤和电子螺杆秤、转子秤。粉末定量进给(皮带秤)是一种用于粉末物料连续自动计量定量进给的调速定量旋转皮带秤。
  With the development of cement industry technology, the improvement of automation of production process and the improvement of economic and technological management level of enterprises, more and more attention has been paid to the measurement and quantitative control of raw material powder entering kiln. Because of the high fineness, low density, dust-prone and good self-flow of raw material and pulverized coal, and the great changes of their state, pressure, moisture and air-filled conditions, it brings more difficulties to the measurement and quantitative feeding control of sand dryer. On the other hand, the production mode, scale and equipment of each cement plant are different. Therefore, the use of curve metering feeding device is also varied. At present, the commonly used sand dryers at home and abroad are quantitative feeding of lifting material (belt scale), mass flow meter, quantitative feeding device of air lift pump, weightlessness feeding scale, electronic screw scale and rotor scale. Powder quantitative feeding (belt weighing) is a kind of speed-regulating quantitative rotary belt weighing scale used for continuous automatic measurement and quantitative feeding of powder materials.
  该系统主要用于干燥机中原料和煤粉的计量和控制。该系统主要包括:预给料机、调速器定量给料秤、称重停止传感器、称重显示控制器等。其结构和工作原理与一般材料相同或相似。其主要区别是在筒仓下必须有预给料装置,如叶轮给料机或流量调节阀。作为干砂机系统的执行机构,调节瞬时进给量,并以带速作为后续调节,使带进给层厚度基本稳定。此外,在物料进入皮带的天坑处还设有特殊结构,以保证物料在皮带上平稳运行,无粉尘。设备安装调试要求,与块状颗粒调速定量送料秤是相同的,当然,对干粉料的特性要求不同,一般秤的尺寸较大,且好使用扑带。

  The system is mainly used for the measurement and control of raw materials and pulverized coal in dryer. The system mainly includes: pre-feeder, governor quantitative feeding scale, weighing stop sensor, weighing display controller, etc. Its structure and working principle are the same or similar to those of common materials. The main difference is that there must be a pre-feeding device under the silo, such as impeller feeder or flow control valve. As the executive mechanism of the dry sand machine system, the instantaneous feed rate is adjusted, and the belt speed is used as the follow-up adjustment, so that the thickness of the feed layer is basically stable. In addition, there is a special structure at the pit where the material enters the belt to ensure the smooth operation of the material on the belt and no dust. Equipment installation and commissioning requirements are the same as the block particle speed regulating quantitative feeding scale. Of course, the characteristics of dry powder are different. The size of general scale is larger, and it is better to use flutter belt.
  干砂机采用倾斜光滑的管式进料,根据预热情况,逐步向干燥筒中添加湿物料,根据物料的含水率排出,逐步增加进料量。为了延长使用寿命的喂食管沙子烘干机,倾斜的滑管可以改变成直管的形式+低槽板,上部是直管,直管是内置在炉墙避免高温氧化和热烟气侵蚀。下段为斜槽板,将从直管上落下的物料连接起来,沿斜面将物料滑入砂干燥机。溜槽板由耐火铸铁制成,由耐火砖支承。
  Dry sand machine adopts inclined and smooth pipe feeding. According to the preheating condition, wet material is gradually added to the drying cylinder, and discharged according to the moisture content of the material, and the feeding quantity is gradually increased. In order to prolong the service life of the feeding esophageal sand dryer, the inclined slide tube can be changed into a straight tube + low groove plate, the upper part is a straight tube, the straight tube is built in the furnace wall to avoid high temperature oxidation and hot smoke erosion. The lower section is inclined groove plate, which connects the material falling from the straight pipe and slides the material into the sand dryer along the inclined plane. The chute plate is made of refractory cast iron and supported by refractory bricks.
