Problems solved by technology

[0004] Due to the gap, random change and temporary shutdown of each working equipment connected to the negative pressure pneumatic conveying system during the working process, such as the shutdown of one or several working equipment, the air flow in the main pipeline 1 will change , which in turn affects the change of airflow in other branch airflow pipes 2, which makes it difficult for the system to achieve an optimal working state, and even produces surge and cannot work stably, which greatly affects product quality
