Description

Technical Field

[0001] The utility model relates to the field of aerosol insecticide preparation, in particular to an aerosol insecticide preparation system. Background Art

[0002] The production and preparation process of aerosol insecticides often requires the use of deodorized kerosene and various insecticide components as raw materials. The deodorized kerosene needs to be stored in a temporary tank before being added to the stirring device. Existing deodorized kerosene temporary storage tanks are often not equipped with impurity filter screens. Even if they are equipped with filter screens, they are not very convenient to clean. When adding various insecticide components to the existing stirring device for aerosol insecticide raw materials, since the insecticide components contain powdered raw materials, they are easy to float on the upper layer of deodorized kerosene when they are just added. In this way, a large amount of insecticide components will accumulate on the upper part of the stirring device and agglomerate into clumps. However, the existing stirring device often cannot have the function of quickly breaking them up, which easily prolongs the stirring time. Utility Model Content
