Organic fertilizer drying system

Abstract

The invention discloses an organic fertilizer drying system. The organic fertilizer drying system comprises a first material extrusion device, a second material extrusion device and a drying device. The first material extrusion device comprises a vertically-arranged first barrel, a first spiral feeding mechanism arranged in the first barrel and a material disc which is arranged on the lower portion of the first barrel in a covering manner and relatively fixed with the first barrel. The second material extrusion device is arranged below the first material extrusion device and comprises a horizontally-arranged second barrel, a second spiral feeding mechanism arranged in the second barrel and a conic funnel arranged at the second end of the second barrel in a sleeving manner. Multiple flow guide grooves are formed in the outer surface of the conic funnel, the flow guide grooves are spirally coiled on the outer surface of the conic funnel, and the cross section of each flow guide groove issemicircular. The drying device is arranged at the second end of the second baffle and receives materials of a discharging opening. The drying device comprises a rotary barrel, a heating plate arranged in the rotary barrel and a driver driving the rotary barrel and the heating plate to independently rotate.

Description

technical field [0001] The invention relates to the technical field of biological organic fertilizer drying, more specifically, the invention relates to an organic fertilizer drying system. Background technique [0002] Organic fertilizers include animal manure or plant debris and other biomass that are accumulated and fermented. The dregs in biogas tanks can also be used as biological fertilizers after sterilization and deworming. Organic fertilizers usually contain more water after accumulation, fermentation, sterilization and deworming, so they need to be dried. [0003] The more traditional and low-cost method is to directly spread the biological fertilizer to dry. This method takes a long time to dry, the moisture content of the drying is uneven, and the efficiency is low. It has gradually become unable to adapt to the large-scale production of biological fertilizer. [0004] The current biological fertilizer production line has generally used dryers to dry biological ...

Problems solved by technology

But there are also disadvantages: the moisture content of the biological fertilizer is high before being put into the dryer, and a large amount of water evaporates after being put into the dryer, taking away a lot of heat, resulting in a waste of resources

[0005] At the same time, in order to pursue the drying speed, the existing drying equipment places too much emphasis on drying in one step, that is, regardless of the moisture distribution of the material, all raw materials are put into the drying equipment for drying together. Such equipment will be affected by the uneven moisture content of the material. drying efficiency
