Description

Technical Field

[0001] This utility model relates to the field of bio-fertilizer and organic fertilizer processing technology, and in particular to a fertilizer cooling device. Background Technology

[0002] Bio-organic fertilizer refers to a type of fertilizer that combines the effects of microbial fertilizer and organic fertilizer by compounding specific functional microorganisms with organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) that have undergone harmless treatment and composting. During the production of bio-organic fertilizer, the powder or granular materials generate high temperatures during processing. Cooling devices are needed to reduce the temperature and prevent heat loss and product quality degradation due to excessive heat.

[0003] For example, a fertilizer cooling device with prior art disclosure number CN219776120U can drive and stir the fertilizer through a transmission cooling mechanism to fully cool the fertilizer, which is beneficial to improving the efficiency and quality of fertilizer cooling. It is equipped with a feeding component, which can cool the fertilizer again when it is fed, further improving the quality of fertilizer cooling.

[0004] When the aforementioned cooling device cools the bio-organic fertilizer powder, the direct cold air intervention through the transmission cooling mechanism can easily cause the powder to disperse through the feed pipe, and during exhaust, the powder is directly discharged through the discharge pipe, causing the powder to disperse and become impossible to collect.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-3 As shown, a fertilizer cooling device is disclosed, comprising a drum 1. A connecting pipe 2 is fixedly connected to the left outer wall of the drum 1. A through hole is opened on the right outer wall of the drum 1. A roller bearing 3 is fixedly connected to the inner wall of the through hole. A feed pipe 4 is fixedly connected to the inner ring of the roller bearing 3. A bearing seat 5 is fixedly sleeved on the outer wall of the connecting pipe 2. Two brackets 6 are fixedly connected to the outer walls of both the bearing seat 5 and the feed pipe 4. A U-shaped base 7 is fixedly connected to the bottom of the brackets 6, and the U-shaped base 7 supports the device.

[0023] A device frame is fixedly connected to the outer wall of the feed pipe 4. A first motor 8 is fixedly connected inside the device frame. The device frame protects the first motor 8. One end of the output shaft of the first motor 8 passes through the outer wall of the feed pipe 4 and is fixedly connected to a spiral conveying rod 9. A feeding pipe 10 is fixedly connected to the top of the feed pipe 4. The roller 1 and the outer wall of the roller bearing 3 are slidably fitted with the same circular frame 11.

[0024] The outer wall of the roller 1 is provided with a drive mechanism, which includes a second motor 14. A gear ring 12 is fixedly sleeved on the outer wall of the roller 1. A frame 13 is fixedly connected to the bottom of the circular frame 11. The inner wall of the frame 13 is fixedly connected to the outer wall of the second motor 14. A gear 15 is fixedly sleeved on the outer wall of the output shaft of the second motor 14. The gear 15 is meshed with the gear ring 12. The operation of the second motor 14 drives the gear 15 and the gear ring 12 to rotate, thereby driving the roller 1 and the conical heat-conducting cylinder 21 to rotate and turn the fertilizer.

[0025] The outer wall of the roller 1 is provided with an air-cooling mechanism, which includes a conical heat-conducting cylinder 21. Multiple air inlets 16 are evenly opened on the outer wall of the roller 1. An air inlet frame 17 is rotatably fitted on the outer wall of the roller 1. An air inlet pipe 18 and an air outlet pipe are fixedly connected to the outer wall of the air inlet frame 17. A blower is fixedly connected to one end of the air inlet pipe 18. When the blower operates, it delivers outside air to the conical cavity between the conical heat-conducting cylinder 21 and the roller 1.

[0026] The inner wall of the roller 1 is fixedly connected to both ends of the conical heat-conducting cylinder 21. The outer wall of the roller 1 has two discharge pipes 19 that are fixedly connected to each other. The outer walls of the two discharge pipes 19 are threaded with sealing caps. The air inlet frame 17 and the U-shaped base 7 are fixedly connected to two support frames 20, which support the air inlet frame 17.

[0027] Working principle: During use, the fertilizer to be cooled is conveyed into the feeding pipe 10 by the existing screw conveyor. The first motor 8 drives the screw conveyor rod 9 to rotate, which drives the fertilizer to be discharged to the discharge port on the left side of the feeding pipe 4 and enters the conical heat-conducting cylinder 21. The fertilizer accumulates continuously. As the second motor 14 operates, it drives the gear 15 to rotate, which in turn drives the gear ring 12 to rotate. The gear ring 12 drives the roller 1 and the conical heat-conducting cylinder 21 to rotate. During the rotation, the raw material is tumbled up and down by its own weight, realizing the throwing process, which is beneficial to the subsequent cooling. The blower operates to bring outside air into the conical cavity between the conical heat-conducting cylinder 21 and the roller 1 through the air inlet pipe 18 and multiple air inlet holes 16, where it exchanges heat with the conical heat-conducting cylinder 21 to cool the fertilizer. During this process, the airflow cannot come into contact with the fertilizer, and cooling is achieved by heat transfer, avoiding the generation of dust. At the same time, when discharging, simply rotate the sealing cover, and the fertilizer is discharged through the two discharge pipes 19.
