Water-soluble fertilizer granulating equipment

Abstract

The invention provides water-soluble fertilizer granulating equipment. The water-soluble fertilizer granulating equipment comprises a machine base, a feed hopper, a conveying feed cylinder, a discharging screen plate, a pelletizing mechanism, a drying reel, a temperature sensor, a humidity sensor and a controller, wherein the feed hopper is arranged above the machine base and comprises a chargingopening and a discharging opening; the conveying feed cylinder is horizontally arranged on the machine base; the discharging screen plate communicates with a discharging opening of the conveying feedcylinder; the pelletizing mechanism is connected with an outlet of the discharging screen plate; the drying reel is connected with the pelletizing mechanism, pellets fall into the drying reel, a plurality of spray nozzles are arranged in the drying reel and are connected with a cooling air tube, and the cooling air tube is connected with a blower; the temperature sensor is arranged in the drying reel and is used for sensing a temperature value in the drying reel; the humidity sensor is arranged in the drying reel and is used for sensing a humidity value in the drying reel; and the controller is connected with the temperature sensor, the humidity sensor, the blower and a heating mechanism. The water-soluble fertilizer granulating equipment is simple in structure, small in investment and lowin maintenance cost, the fertilizer baking is free of dead corners, and thus, the water-soluble fertilizer granulating equipment has a relatively high marketing value.

Description

technical field [0001] The invention belongs to water-soluble fertilizer granulation equipment. Background technique [0002] At present, granulation drying equipment has become very popular and widely used in various industries. In the molten material granulation equipment, there are mostly three forms: one is high-tower melting granulation, that is, a granulation head is installed in the granulation tower, and after the molten material is sprayed out by the granulation head, it is freely processed in the granulation tower. The falling movement solidifies gradually during the falling process. This kind of equipment needs a corresponding height to meet the solidification requirements. Therefore, the general prilling towers are relatively high, and the equipment has a high one-time investment and high energy consumption; the second is the steel belt melting production. granules, the granules made are mostly semi-circular granules, and the granule diameter is large, which can...

Problems solved by technology

In the molten material granulation equipment, there are mostly three forms: one is high-tower melting granulation, that is, a granulation head is installed in the granulation tower, and after the molten material is sprayed out by the granulation head, it is freely processed in the granulation tower. The falling movement solidifies gradually during the falling process. This kind of equipment needs a corresponding height to meet the solidification requirements. Therefore, the general prilling towers are relatively high, and the equipment has a high one-time investment and high energy consumption; the second is the steel belt melting production. granules, the granules made are mostly semi-circular granules, and the granule diameter is large, which cannot meet the needs of industries with special requirements for granules. At the same time, the steel belt must be replaced regularly, and the maintenance cost is high; the third is the drum slicer, and the finished products are more It is flaky, the fluidity of the material is poor, and it is gradually replaced by round particles
