A processing method of a quantitative compound fertilizer granulating device comprises the following steps:
the method comprises the following steps: firstly, operating the controller to open a bucket elevator switch, placing prepared urea in the bucket elevator, urea falls into a bearing plate in a quantitative barrel along with the bucket elevator, the bearing plate presses down two pressure sensors at the bottom of the bearing plate, the pressure is increased along with the increase of the urea, a signal is sent to the controller until the pressure sensors reach preset weight, so that the bucket elevator is closed by the controller, operating the controller to open a first push rod and a vibration motor switch respectively at the moment, an output shaft of the first push rod drives a sealing block to slide downwards in a limiting groove of the bearing plate, and the quantitative urea enters into a stirring kettle along with a first connecting pipe along with the vibration of the vibration motor.
Step two: when urea gets into to the stirred tank in, can fall into to the heat-conducting plate on, the annular heating pipe of heat-conducting plate bottom is opened to the operation control ware, thereby heat stirred tank inside, become the molten state until urea, first motor switch is opened to the operation control ware this moment, the output shaft of first motor drives the stirring rake and rotates the urea under the molten state and stir, along with the stirring back, the molten urea can enter into to the ratio cauldron through second communicating pipe, the second communicating pipe is close to the bottom in stirred tank in-connection position.
Step three: after molten urea enters the proportioning kettle, powdery ammonium phosphate, powdery ammonium chloride and the like which are prepared in advance are poured into a feeding box according to a certain proportioning amount of the molten urea, a large amount of biuret is produced for avoiding errors, two second push rods and two bottom doors are installed for handle control, two second push rod switches and a first spiral conveyor are opened by a control device, two bottom doors are opened by output shafts of the two second push rods, the powdery ammonium phosphate, the powdery ammonium chloride and the like enter the proportioning kettle along the first spiral conveyor, then the second motor switch is opened by the control device, the output shaft of a second motor drives a stirring rod to rotate through a coupler, and the molten urea, the powdery ammonium phosphate, the powdery ammonium chloride and the like are uniformly stirred in a fixed ratio to form a mixed solution.
Step four: after the mixed solution is formed, putting the compound fertilizer particle semi-finished product prepared in advance into the rotary drum granulator, spraying the mixed solution into the rotary drum granulator along one end of a third communicating pipe, wrapping the compound fertilizer particle semi-finished product inside the rotary drum granulator to form compound fertilizer particles, then enabling the compound fertilizer particles to enter a drying box along a conveyor belt and a first conveying groove, and collecting part of the accidentally scattered compound fertilizer particles by a collecting groove.
Step five: after the compound fertilizer granule enters into stoving case, thereby fall into on the conveyer belt, four heating resistor silk switches are opened to the steering control ware, thereby four heating resistor silk are dried the compound fertilizer granule of stoving incasement portion, the steering control ware opens the third motor switch after the stoving, the output shaft of third motor drives and corresponds a commentaries on classics roller and rotate, thereby it drives conveyer belt rotation to change the roller, and then compound fertilizer fast granule after the stoving enters into the cooling passage in the cooler bin, steering control ware opens two radiator fan switches, thereby two radiator fan carry out the air-cooling to compound fertilizer granule on the conveyer belt, enter into to second screw conveyer along the second conveyer trough after the cooling.
Step six: after the compound fertilizer granules enter the second screw conveyer, the compound fertilizer granules enter the third conveying groove along the second screw conveyer, then enter the screen mesh in the separating box along the third conveying groove and the material receiving groove, the fourth motor switch is turned on by the operation controller, the output shaft of the fourth motor drives the corresponding rotating shaft to rotate, the rotating shaft drives the flywheel fixedly connected with the rotating shaft to rotate, the flywheel drives another group of flywheel and the rotating shaft to rotate through the rotating belt, the two rotating shafts drive the four cams to rotate, and then the four cams drive the screen mesh to vibrate up and down, so that the standard compound fertilizer granules of the screen mesh can fall into the material collecting box at the bottom through the discharging groove.
The invention has the beneficial effects that:
1. firstly, operating a controller to open a switch of a bucket elevator, placing prepared urea in the bucket elevator, enabling the urea to fall onto a bearing plate in a quantitative barrel along with the bucket elevator, enabling the bearing plate to press down two pressure sensors at the bottom of the bearing plate, increasing the pressure along with the increase of the urea, sending a signal to the controller until the pressure sensors reach a preset weight, thereby closing the bucket elevator by the controller, operating the controller to open a first push rod and a vibration motor switch respectively, driving a sealing block to slide downwards in a limiting groove of the bearing plate by an output shaft of the first push rod, driving the quantitative urea to enter a stirring kettle along with a first communication pipe along with the vibration of the vibration motor, after the urea is quantitatively dispensed, driving the sealing block to slide downwards by the first push rod at the bottom, and often blocking the urea from the first communication pipe to enter the stirring kettle, and the vibrating motor that the support frame bottom was equipped with can be with accumulational urea vibration, and then get into stirred tank smoothly, and the volume of urea in the quantitative bucket can effectively be controlled to two pressure sensor's setting.
2.
