Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer production technology, specifically relating to a drying device for organic fertilizer production. Background Technology

[0002] Carbon-containing materials primarily derived from plants and / or animals, applied to the soil to provide plant nutrition as their main function. Processed from biological matter, animal and plant waste, and plant residues, they eliminate toxic and harmful substances and are rich in beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. They not only provide comprehensive nutrition for crops but also have a long-lasting effect, increasing and renewing soil organic matter, promoting microbial reproduction, and improving the soil's physical, chemical, and biological properties. They are a key nutrient for green food production. Drying equipment refers to a combination of mechanical devices that use specific techniques to dry the surface moisture or other liquids of objects.

[0003] Traditional drum-type drying equipment generally suffers from technical bottlenecks such as material accumulation and low heat exchange efficiency. Specifically, when organic fertilizer raw materials with high moisture content enter the drying drum, they tend to form a static accumulation layer at the bottom of the drum due to gravity. This causes the surface material to be overheated and carbonized, while the internal material remains moist. This localized temperature difference not only prolongs the drying cycle but also damages the active components of organic matter due to continuous high temperatures. Therefore, a drying device for organic fertilizer production is needed to help solve this problem. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a drying device for organic fertilizer production, such as... Figure 1-4As shown, the drying device for organic fertilizer production includes a drying cylinder 1. A funnel-shaped drying chamber is formed at the inner edge of the drying cylinder 1. Several baffles 3 are fixed inside the drying chamber, arranged in a circular array around the axis of the drying cylinder 1. The drying cylinder 1 protrudes from the drying chamber. A receiving box 13, funnel-shaped, is embedded at one end of the feed inlet of the drying cylinder 1. A filter screen 14 is installed on the receiving box 13, and a base frame 12 is fixed at the bottom of the receiving box 13. A fixed frame is fitted at the middle section of the drying cylinder 1. The drying cylinder 1 has a meshing gear ring 9 and a base 4 installed below it. A transmission assembly 5 that works with the meshing gear ring 9 is installed at the top middle section of the base 4. The transmission assembly 5 includes a transmission motor 8 installed at the top of the base 4. A reduction gear box 6 is installed at the front end of the shaft of the transmission motor 8. A meshing gear 7 is installed at the output end of the reduction gear box 6. The meshing gear 7 meshes with the meshing gear ring 9. In actual operation, a sealing cover can be installed at the discharge port of the drying cylinder 1. A hot air pipe is embedded in the sealing cover to ensure stable airflow inside the drying cylinder 1.

[0027] By setting a funnel-shaped drying chamber on the inner edge of the drying cylinder 1, the material forms a dynamic throwing trajectory along the slope of the chamber during rotation. Combined with the ring array structure of the blocking blades 3, the material is turned over in multiple stages and fully contacted with the hot air, avoiding drying dead corners caused by local accumulation and improving drying uniformity.

[0028] A guide rail 2 is fitted around the outer edge of the drying cylinder 1. A fixed seat 10 is symmetrically installed on the top of the base 4. A guide wheel 11 is rotatably mounted on the fixed seat 10. The guide rail 2 and the guide wheel 11 cooperate to support each other. Through the cooperation between the guide wheel 11 and the guide rail 2, the two ends of the drying cylinder 1 can be effectively supported, ensuring that the drying cylinder 1 can rotate stably and dry.

[0029] The filter screen 14 is inserted and installed on the receiving box 13. A ring is fixed to one end of the receiving box 13 that extends out of the filter screen 14. A discharge port is provided on one side of the receiving box 13. An embedded ring 131 is installed at the discharge port. The embedded ring 131 is rotatably embedded in the drying cylinder 1. The embedded ring 131 can ensure a stable connection between the receiving box 13 and the drying cylinder 1 when the drying cylinder 1 rotates.

[0030] The filter screen 14, a key component of the receiving box 13, pre-screens the material entering the drying cylinder 1. Through its plug-in installation structure, the filter screen 14 effectively intercepts large particles, clumps, or fibrous foreign objects mixed in the material, preventing such foreign objects from entering the drying chamber and causing jamming of the conveying component 15 or uneven drying. The detachable design of the filter screen 14 allows for the use of different sizes of filter screens 14 when drying fertilizers of different specifications, improving the overall practicality of the device.

[0031] Furthermore, a spiral conveying assembly 15 is rotatably installed at the bottom of the receiving box 13, and a rotating motor 16 is installed on the outer side of the receiving box 13 to drive the conveying assembly 15 to rotate. Through the conveying assembly 15, quantitative feeding can be achieved during drying, ensuring that the organic fertilizer can enter the drying cylinder 1 in a quantitative manner, and avoiding situations such as excessive accumulation of organic fertilizer causing inadequate drying.

[0032] Working principle:

[0033] The material enters the funnel-shaped receiving box 13 through the feed inlet. The plug-in filter screen 14 performs preliminary filtration of the material, intercepting large particles or clumps. The rotating motor 16 drives the spiral conveying assembly 15 to rotate, pushing the filtered material evenly into the drying cylinder 1 to avoid material accumulation and blockage.

[0034] During drying, the drive motor 8 drives the meshing gear 7 to rotate through the reduction gear box 6. The meshing gear 7 meshes with the meshing gear ring 9 to drive the drying cylinder 1 to rotate at low speed around the axis. The guide rail 2 and the guide wheel 11 cooperate to support the drying cylinder 1 and ensure rotational stability.

[0035] The annular array of baffles 3 inside the drying cylinder 1 rotates with the cylinder body, continuously turning the material, so that the material forms a dynamic fluidized state in the funnel-shaped drying chamber, increasing the contact area with hot air. The dried material is discharged through the outlet embedded ring 131. The opening of the outlet embedded ring 131 can be adjusted by rotating it to control the discharge speed.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
