Description

Technical Field

[0001] The utility model relates to the technical field of insecticide dehumidification dryers, in particular to a layered dehumidification dryer for small and medium granular insecticides. Background Art

[0002] Granular insecticides are a common form of pesticides. Usually, the active ingredients of insecticides are made into granules for easy use and application. In the process of producing granular insecticides, drying is usually required. The main purpose of drying is to remove moisture from the granules, improve the stability and shelf life of the granules, and also help reduce the agglomeration between the granules for easy packaging and transportation. In the production process of granular insecticides, granular insecticides usually go through steps such as mixing, granulation, and drying. After granulation, a certain amount of moisture may remain in the granular insecticides. If drying is not performed, the granules will absorb moisture and agglomerate, affecting the quality and stability of the product. Drying treatment usually adopts methods such as drying or fluidized bed drying. The granules are heated by hot air or other heat sources to evaporate the moisture in the granules to achieve the drying effect. Drying treatment can not only improve the quality and stability of the product, but also improve production efficiency and reduce problems during packaging and storage.

[0003] A stratified dehumidification dryer for small and medium-sized granular insecticides is disclosed in the Chinese utility model patent application disclosure CN204165359U. Although the stratified dehumidification dryer for small and medium-sized granular insecticides provided by the utility model has three drying chambers, each of which introduces an air duct and a dehumidification channel, thereby improving the drying efficiency of small and medium-sized granular insecticides and ensuring uniform drying of small and medium-sized granular insecticides, the utility model, when actually used, only blows hot air into the drying chamber for drying. If there are a lot of granular insecticides, they are easy to accumulate, and it is difficult for hot air to blow into the interior of the granular insecticides. The granular insecticides inside are not easily blown by the hot air, resulting in a poor drying effect. Therefore, a stratified dehumidification dryer for small and medium-sized granular insecticides is urgently needed to solve the above problems. Utility Model Content

[0037] In order to further improve the drying effect, Figures 1 to 10As shown, the present application adopts the following structure. Through the arrangement of the second drying chamber 1, the bottom plate 3, the turntable 10, the inverted cone-shaped spray slot 11, the spiral drying rack 15 and the discharge funnel 21, the medium and small granular insecticide stratified dehumidification dryer has the effect of facilitating the drying effect of the granular insecticide. In actual use, the granular insecticide that has been preliminarily dried in the first drying chamber 17 is discharged from the lower end of the discharge funnel 21. When discharged, the telescopic rod of the second electric telescopic rod 19 is retracted, driving the fan-shaped door cover 18 to rotate outward, so that the lower The upper end of the material funnel 21 is opened, and the granular insecticide falls into the interior of the second drying chamber 1.

Therefore, the granular insecticide can be dried again while sliding down the spiral drying rack 15, and the water is discharged from the moisture discharge pipe 20 after evaporation. After the granular insecticide is dried, the motor 8 drives the rotating shaft 9 to rotate in the opposite direction, thereby driving the scraper 14 to rotate in the opposite direction, and the granular insecticide is pushed to the outside of the upper surface of the bottom plate 3. At this time, the telescopic rod of the first electric telescopic rod 6 is retracted, driving the block 5 to move and opening the slot 4. At this time, the dried granular insecticide can be discharged from the discharge port 7, thereby achieving the purpose of further improving the drying effect.
