Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, specifically to a drying device for organic fertilizers. Background Technology

[0002] Organic fertilizers, also known as organic chemical fertilizers, refer to carbon-containing materials derived from animal and plant residues, excrement, or biological metabolites that provide nutrients to plants after decomposition and fermentation. Their core characteristic is that the raw material is biomass, and nutrients are slowly released through microbial decomposition. Unlike the rapid effects of chemical fertilizers, organic fertilizers must be dried after processing. Drying can significantly reduce water content to within the compliant range, preventing clumping, mold growth, or nutrient loss due to excessive moisture. At the same time, it can prevent the particles from shrinking and solidifying due to heat during the drying process, increasing mechanical strength and ensuring the integrity during packaging, transportation, and application, thus maintaining commercial quality.

[0003] A search revealed an existing technology (publication number: CN214199553U) for drying organic fertilizers. The technology describes a device that "includes a drying chamber, a feed pipe, a fixed slide rail, a storage box, a displacement adjustment assembly, a blower, a heating chamber, and a hot air nozzle. The drying chamber has a feed inlet at the top, the feed pipe is located on the feed inlet and within the drying chamber, the fixed slide rail is symmetrically arranged on two opposite side walls of the drying chamber, the storage box has extension plates on both sides, the extension plates have sliding protrusions that slide on the fixed slide rails, and the drying chamber has a drive cavity on its side wall." However, this existing technology is not conducive to breaking up fertilizers, resulting in poor drying effects on clumps of fertilizer. Therefore, designing a drying device for organic fertilizers is essential. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for organic fertilizers, which solves the problem in related technologies that it is not easy to break up the fertilizer during use, resulting in poor drying effect on clumped fertilizers.

[0005] The technical solution of this utility model is as follows:

[0006] A drying device for organic fertilizer includes a drying cylinder. A connecting pipe is inserted into the bottom of the drying cylinder, and drying holes are provided on both sides of the outer wall of the connecting pipe. A metal filter cylinder is screwed onto the outside of the drying holes. Two connecting brackets are screwed onto the connecting pipe, and several vertical rods are welded at equal intervals between the two connecting brackets. A drive gear is welded to one end of the bottom of the connecting pipe. A motor is screwed onto the bottom end face of the drying cylinder, and a transmission gear is welded to the output end of the motor. The transmission gear meshes with the drive gear. Support rods are welded to both sides of the outer wall of the drying cylinder. Supports are provided on both sides of the drying cylinder, and two support rods are respectively inserted and fixed to two supports. One of the support rods passes through the support and is welded with a handwheel.

[0007] Preferably, a sealing tube is screwed to the bottom of the drying cylinder, and the outer wall of the connecting tube is in contact with the inner wall of the sealing tube. The metal filter cylinder is made of stainless steel.

[0008] Preferably, a pair of reinforcing rods are welded between the two brackets.

[0009] Preferably, a heating box is screwed to the bottom end face of the drying cylinder, and a conveying pipe is screwed to the bottom of the heating box. One end of the conveying pipe is connected to the interior of the heating box, and the other end of the conveying pipe is inserted and connected to the bottom of the connecting pipe.

[0010] Preferably, a power supply is screwed into the interior of the heating box, and a drying rack is screwed onto the outside of one side of the power supply. The drying rack is electrically connected to the power supply, and several heating tubes are provided inside the drying rack. Heat dissipation vents are provided on both outer walls of the heating box.

[0011] Preferably, another support rod passes through the bracket and is welded with a limiting frame, and the limiting frame has several limiting holes equidistantly opened on its periphery. A positioning frame is screwed to the top of the outer wall of the other bracket, and a plug is inserted into the positioning frame, with one end of the plug extending into a limiting hole.

[0013] Preferably, finger grooves are provided on both sides of the sealing cap.

[0014] The beneficial effects of this utility model are:

[0015] The metal filter cartridge can block the drying holes, preventing fertilizer from entering the connecting pipe. At the same time, it can also filter the hot air inside the connecting pipe. The motor drives the transmission gear to rotate, which synchronously drives the connecting pipe to rotate, ensuring even heating inside the drying cylinder. When the connecting pipe rotates, it drives the vertical rod to rotate through the connecting frame, which helps to disperse the fertilizer. Turning the handwheel can rotate the drying cylinder, which helps the fertilizer to tumble inside the drying cylinder, improving the dispersion effect and thus enhancing the drying effect.

[0016] Air enters the heating chamber through the heat dissipation vent and is heated by an electric heating element. Heat is transferred from the heating chamber to the connecting pipe through the delivery pipe, and the heat is released from the drying hole to dry the fertilizer. Moisture generated during drying is discharged through the dehumidification port. The moisture in the drying cylinder is quickly extracted by the exhaust fan. The filter screen prevents fertilizer from entering the dehumidification port and causing blockage. The filter cloth provides secondary filtration. Attached Figure Description
