pneumatic conveying system. After calculating or identifying the material flow type, dilute or dense phase pneumatic conveying facilities can be selected, and then the following specific steps are designed:
1. In addition to the general requirements introduced above, compared with facility design, the following points should be considered for collection of design-related information:
(1) For facilities between processes in the factory, attention should be paid to the connection between the front and rear processes, and the system entry and exit method should be selected;
(2) Pay attention to material characteristics and process standards, as well as the impact of pneumatic conveying;
(3) Pay attention to hygiene, mainly exhaust gas treatment and noise treatment. Pneumatic conveying design
2. After the transportation facility layout system is selected, the system layout can be done. When laying out, the position of the starting feeder or suction nozzle and the position of the end separator can be determined according to the factory facility layout diagram, then the position of the air compressor and auxiliary facilities can be determined, and the configuration of the air pipelines and conveying pipelines, the total number of pipe fittings and bent pipes, etc. At this time, based on each part of the system. .Structure and performance have been roughly mastered, so after the layout is completed, the construction drawing design can be started. When laying out the pipeline, pay attention to reducing the total number of bent pipes, and pay attention to keeping each section of horizontal pipe not too long during long distance transportation. The pipes passing through the outdoors should be kept in heat to prevent the inner walls of the pipe from condensing and sticking to the walls of the pipes. Pipe fittings that are avoided to be installed on material conveying pipes.
3. Establish the type and structure of key components, and establish the type and structure of key components. Generally speaking, the suction nozzle and separator are mainly used for suction conveyors and feeders. The cylinder pneumatic conveying facilities mainly have transceivers, and the round-trip transportation facilities should have an exchange station. Establish an automatic control mode. Programs and lines are very important for all pneumatic conveying facilities, and are sometimes key.
4. When the system of a rough calculation equipment needs an air volume calculation facility system, it mainly requires air volume calculation, which is convenient for roughly establishing gas top machinery. The system requires air volume as the product of air volume and pressure. The amount of air can be calculated by the selected main parameters. Therefore, the main task of rough calculation is to roughly calculate the wind resistance of the facility system.
5. Accurately calculate each data of the facility system. Generally, general calculation is a rough calculation and a simple calculation method when establishing a facility system plan. Therefore, after the plan is established, accurate calculations must be done one by one to finally determine all the sizes of the system.
