Application method of air pipe type fertilizer drying machine with vibrating screen

Abstract

The invention provides an application method of an air pipe type fertilizer drying machine with a vibrating screen. The method comprises the following steps that A, a heater is connected to an air pipe and connected with a thermostat, and the heater is electrically connected with an external power supply; B, the upper portion of a feed port is connected with a conveying belt for the previous palletizing process through a conveying belt, and granulated fertilizer obtained in the palletizing process is led into a drying cylinder along the feed port; C, a motor is turned on, a draught fan is turned on, the motor drives an auger to rotate, the granulated fertilizer is heated to 60-80 DEG C by the heater arranged in the step A and enters the auger along the air pipe, the draught fan blows out hot air along air outlet holes, the granulated fertilizer is dried while being stirred, and the stirring speed is 30 revolutions per minute; D, materials per drying cylinder is dried for 5-8 minutes, then a discharge port is opened, and the dried granulated fertilizer is led out and goes to the next cooling process. The method has the advantages that manufacturing is easy, the process is simple, and the air pipe type fertilizer drying machine is simple in structure, convenient to use, low in energy consumption, uniform in drying and high in speed.

Description

[0001] technical field : [0002] The invention relates to the technical field of machinery for organic fertilizer production, in particular to a method for using an air duct type fertilizer dryer with a vibrating screen. [0003] Background technique : [0004] In the production process of organic fertilizers and compound fertilizers, drying equipment is required to dry fertilizers with a certain humidity and particle size, and can also be used for drying other materials. Most of the current dryers use the drum type, which has disadvantages such as unreasonable material plate distribution and angle design, low heat energy utilization rate, and uneven drying. Moreover, the current drying equipment adopts heating type drying, and there is uneven heating, which leads to the problem of uneven drying. In view of this technical problem, it is necessary to explore a kind of air-drying drying equipment, which is easy to manufacture. , the process is simple, the structure of th...
