Embodiment Construction

[0017] Examples see figure 1 , 2 , 3. This kind of continuous slow and controlled release fertilizer production device has a long cylindrical drum 1, with a feed port 2 at the front end of the drum, a discharge port 3 at the back end, and the discharge port is connected to a cooling mechanism 4. The hoisting hopper 5 is evenly arranged on the inner wall of the rotating drum. The lifting hopper 5 is shaped like a bucket of a waterwheel.

[0018] The upper preheating fluidized bed 6 and the lower preheating fluidized bed 7 are arranged in the axial direction in the front half of the rotating drum. The preheating fluidized bed is formed by fixing the bed body of the fluidized bed on the preheating tube. Pass heat medium. A funnel trough-shaped collecting bed 8 is arranged along the extension line of the upper fluidized bed in the second half of the rotating drum, and a spraying pipe 11 is arranged under the discharge port of the narrow and long funnel and parallel to the collecting ...

Abstract

The continual buffle-control release-fertilizer manufacture equipment comprises, a long-barrel revolving drum with feed opening on front end connected to cooling mechanism and discharge opening on back end; arranging lifting hopper along the inner wall of revolving drum; arranging upper and lower groups of preheating fluid bed on front segment of the drum axially; arranging hopper slot-shaped flow collection bed along prolong line of upper fluid bed on back segment of the drum; arranging spraying pipe distributed with nozzles below the discharge opening and parallel with flow collection bed; connecting fusion and quantitative convey device for coating agent out of the spraying pipe; connecting the revolving drum to dust collector, and links with fan, air heater, air inlet in series to form preheating utility cycle loop.

Description

(1) Technical field [0001] The invention relates to a fertilizer production device, in particular to a production device that continuously completes turning, drying, and coating. (2) Background technology [0002] Slow and controlled release fertilizer is a coated fertilizer that can release fertilizer slowly. Existing slow and controlled release fertilizer production devices, such as the Chinese patent (CN1135745A) applied by American Aye Lexi Technology Co., Ltd., must be sprayed by a sprayer and cooled after the fluidized bed drying process is discharged. To complete the production of slow and controlled release fertilizers, this production method has many processes, complicated equipment, large floor space, amazing energy consumption, only intermittent operation, not continuous operation, and low production efficiency. Not only that, the existing spraying machine can only meet the production needs of slow and controlled release fertilizers with a single coating material, and ...
