(Summary description)Due to its physical properties, powder is likely to cause dust, leakage, pollution, etc. during the conveying process. According to different material characteristics and specific working conditions, different conveying methods are selected to match different production conditions. Common powder conveying methods include: positive pressure pneumatic conveying, negative pressure pneumatic conveying and other pneumatic conveying methods, as well as conveyor belts, elevators and other mechanical conveying methods. The following will introduce the selection method of powder pneumatic conveying. Before deciding which conveying method to choose, we need to clarify the design details in the process to ensure that the appropriate conveying method is selected: (1) Determine the conveying distance In the process of powder conveying, the difference in conveying distance greatly affects the choice of conveying method. For example, the production link of the upper and lower structure is also from top to bottom, which can be directly dropped from the upper layer of equipment to the next layer of equipment by gravity. Similar to this kind of short-distance transportation with upper and lower structures, the chute can be directly used, which is economical and economical. Affordable and durable. However, with the development of economy and technology, production has entered the era of 4.0, and the production of all walks of life has become large-scale, large-scale, standardized and intelligent. Often, the conveying distance of materials in production can reach 100 meters. At this time, the pneumatic conveying method is selected. It will greatly improve the conveying speed and efficiency of materials. (2) Determine the direction of the pipeline In the design of powder conveying, the direction of the pipeline during the conveying process should be considered. The direction of the pipeline should comprehensively consider practical factors and aesthetic factors. Pneumatic conveying often has a simple pipeline layout, which does not affect the operation of other equipment in the production process. The conveying can also be connected to the original equipment, so that the whole production process can realize continuous production with a high degree of automation. (3) Determine the nature of the material Different material properties are a major factor affecting the choice of powder conveying methods. For example, dust-prone, toxic and harmful materials are not suitable for mechanical conveying methods such as bucket elevators. The use of closed pneumatic conveying technology can avoid powder dust pollution and damage to operators. There is also a certain emphasis on the selection of pneumatic conveying. For example, due to the relatively fast conveying speed of positive pressure dilute phase pneumatic conveying, the material is likely to rub against the pipe wall to generate heat, so the method of positive pressure dilute phase pneumatic conveying is not suitable for conveying plastics Particles, powdered sugar and other materials that are more sensitive to heat.
