LS螺旋输送机设计

摘要 ：LS型螺旋输送机是采用国际标准产品,等效采用ISO1050-75标准,设计制造符合ZBJ1005.1-2-88专业标准。其技术指标先进，结构新颖，是我国九十年代替代GX型螺旋输送机的换代产品。LS型螺旋输送机的应用范围：螺旋机被广泛地使用在各种工业部门，如建材、电力、化工、冶金、煤炭、机械、轻工、粮食及食品行业。
    LS螺旋输送机对输送物料的要求，粉状、粒状和小块状物料。如：水泥、煤粉、粮食、化肥、灰渣、砂子等，物料温度不得超过200℃，螺旋机不宜输送易变质的、粘性大的、易结块的物料。因为这些物料在输送时在一螺旋上，并随之旋转而不向前移动，或者在吊轴承处形成物料的积塞而会粘结使螺旋机不能正常工作。LS螺旋机的工作环境应在-20℃~50℃之间，允许稍微倾斜使用，最大倾角不得超过20℃。
  本次LS螺旋输送机设计主要分析了粉状物料输送的相关参数。 要求被输送物料的名称及特性来设计，按螺旋输送机驱动方式，我们选择了单端驱动。查阅了相关资料，才完成图纸模型到图纸数据，这都是强有力的效果。

LS spiral conveyer design
Abstract: The LS spiral conveyer uses the international standard product, equivalent uses the ISO1050-75 standard, the design manufacture conforms to the ZBJ1005.1-2-88 specialized standard. Its technical specification is advanced, the structure is novel, is our country substitutes the GX spiral conveyer's update product in the 90s. LS spiral conveyer's application scope:The screw machine widely is used in each Industry sector, like building materials, electric power, chemical industry, metallurgy, coal, machinery, light industry, grain and food profession.
   The LS spiral conveyer to transports the material the request, powdery, granular and small massive material. For example: The cement, the powdered coal, the grain, the chemical fertilizer, the ash dregs, the sand and so on, the material temperature do not surpass 200℃, the screw machine is not suitable transports the material which the instable archery target, the coherency big, easy to agglomerate. Because these materials in transportation time will cake on a screw, and along with it revolving, but not the forward motion, or will form the material in the suspension bearing place the product to fill enables the screw machine the normal work. The LS screw's machine working conditions should in - 20℃~50℃, the permission incline slightly the use, the maximum inclination angle do not surpass 20℃.
   This LS spiral conveyer design has mainly analyzed the powdery material handling's related parameter. The request is transported the material the name and the characteristic designs, according to the spiral conveyer drive type, we have chosen the single end actuation. Has consulted the correlation data, only then completes the blueprint model to the blueprint data, this is the powerful effect.
