Embodiment Construction

[0016] like figure 1 As shown, an industrialized production device for thermosetting resin-coated controlled-release fertilizer includes a preheating device 1. The preheating device 1 can use a vibrating fluidized bed for preheating or a silo with a heating coil. The outlet of the preheating device 1 is equipped with an electronic weighing scale 2 and a belt conveyor. The end of the belt conveyor is connected to the elevator 3, and the outlet of the elevator 3 is connected to the entrance of the heating bin 7. The outlet of the heating bin 7 is equipped with a direct heating disc 4 for direct heating. The outlet of the disk 4 enters the heating drum 10 through the conveyor belt 5 and the screening machine 6, and the outlet of the heating drum 10 is connected to the finished product bin 12 through the finished product belt conveyor 11.

[0017] The production device includes a resin metering and spraying device 8 and a curing agent metering and spraying device 9, the nozzle of ...

Abstract

The invention discloses an industrial production device for a thermosetting resin coated controlled-release fertilizer. The device comprises a preheating device, a hoisting machine, a heating device, a heating disk, a rotary drum and the like which are connected, wherein the disk is a direct-heating type disk; the rotary drum is a direct-heating type rotary drum the inclined angle of which can beadjustable; the disk and the rotary drum are externally connected with a material inlet and a material outlet respectively; a resin spraying tube is arranged above the disk surface of the disk; and the resin spraying tube is connected with a resin metering and spraying device. A material is preheated and then enters into the disk for polishing and pre-spraying; then the discharged material entersinto the drum, wherein a curing agent spraying tube is arranged at the material inlet end of the drum and connected with a curing agent metering and spraying device; and the material is sprayed by a curing agent in the drum and cured and then discharged and packaged. Compared with the prior art, the industrial production device has the advantages of high heat utilization rate, rapid curing time, low loss and high production efficiency.

Description

technical field [0001] The invention relates to an industrialized production device for thermosetting resin-coated controlled-release fertilizer. Background technique [0002] Thermosetting resin-coated controlled-release fertilizer is a kind of coated controlled-release fertilizer, which can release the fertilizer effect slowly. The existing thermosetting resin-coated controlled-release fertilizer production process generally adopts hot air heating, which has low heat utilization rate, long resin curing time, high loss of film materials, and low production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a device capable of large-scale production of thermosetting resin-coated controlled-release fertilizers, which solves the defects of low heat utilization rate, slow curing time, high loss and low production efficiency of existing devices. [0004] To achieve the above object, the present invention adopts the following tech...
