Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pesticide powder drying, specifically relates to a vibrating fluidized bed dryer with dust collection. BACKGROUND

[0002] Pesticide technical material and some auxiliary ingredients may contain a certain amount of moisture in the processing process. Too much moisture will affect the stability, flowability and storability of the powder pesticide. For example, too high moisture content may cause the pesticide to clog during storage, affecting its use effect, and drying can effectively remove these moisture to ensure product quality, so a vibrating fluidized bed dryer is used in the process of pesticide powder technical material production.

[0003] The working principle of the existing vibrating fluidized bed dryer is to use the combined action of vibration and airflow to dry the material in a fluidized state. Through the synergistic action of vibration and airflow, the vibrating fluidized bed dryer can realize efficient and uniform drying process, and is suitable for drying various granular and powdery materials, with the advantages of fast drying speed, good drying quality and low energy consumption.

[0004] However, the existing vibrating fluidized bed dryer does not have a preliminary filtering mechanism during operation, so it exposes a significant problem. During the drying operation, hot air flows from the bottom of the equipment, carrying the evaporated water vapor in the material upwards. In this process, the fine dust on the surface of the material is easily wrapped by the rising drying airflow. However, the existing vibrating fluidized bed dryer lacks a preliminary filtering mechanism for the dust in the rising drying airflow, and a large amount of dust directly enters the subsequent bag dust collector without pretreatment. Over time, the bag dust collector needs to withstand a pressure far exceeding the design load, causing the internal filter bag to frequently clog, significantly shortening the dust cleaning cycle, and thus seriously affecting the dust removal efficiency of the bag dust collector. Not only does it reduce the running stability of the entire drying system, but it also may cause the product quality to decline and even pollute the production environment. SUMMARY
