Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to high-efficiency cooling equipment for organic fertilizer production. Background Art

[0002] Organic fertilizer refers to carbon-containing materials derived primarily from plants or animals and applied to the soil to provide plant nutrition. Also known as farmyard manure, it includes various types, such as human waste, manure, compost, green manure, cake fertilizer, and biogas fertilizer. These fertilizers come from a wide range of sources, including the excreta or residues of all organisms, as well as their decomposition products. Organic fertilizers contain a variety of nutrients, including nitrogen, phosphorus, and potassium, as well as a variety of organic acids, peptides, and a rich variety of growth factors, such as vitamins, hormones, and enzymes. These ingredients help provide crops with a more comprehensive nutrient profile, promoting healthy growth. During the production process of organic fertilizer, such as fermentation and drying, high temperatures are generated. Cooling can reduce the temperature of the fertilizer, preventing it from deteriorating or being damaged by high temperatures. Cooling helps stabilize the active ingredients in organic fertilizer, such as microorganisms and enzymes, thereby improving its efficiency and effectiveness. Furthermore, cooled organic fertilizer maintains a moderate temperature, making it less susceptible to spontaneous combustion or deterioration, and thus improving safety during storage and transportation. Cooling equipment is usually used to cool organic fertilizer after drying. Currently, most cooling equipment uses air cooling. However, due to the clumping of organic fertilizer after drying and the large amount of organic fertilizer put into the equipment, some organic fertilizer cannot fully contact the cold air, resulting in poor cooling effect and low efficiency.

The second cold air ducts 21 are fixedly connected to the air nozzles 22. The upper end of the recooling box 17 is fixedly connected to the industrial cold air fan 16. The output end of the industrial cold air fan 16 is fixedly connected to the tee through a pipe.

Its specific structure will not be described in detail in this embodiment.

[0021] In order to further stir and decompose the broken organic fertilizer and ensure that all materials are dispersed, a stirring rod 4 is fixedly connected to the lower part of the rotating shaft 2.

[0022] In order to ensure that the material falling from the discharge pipe 12 falls accurately on the vibration trough 7, a downwardly inclined material guide plate 15 is fixedly connected to the inner wall of one side of the primary cooling box 6, and the downwardly inclined end of the material guide plate 15 is located directly above the input end of the vibration trough 7.

[0029] The working process of this embodiment is as follows:

[0030] After the organic fertilizer is dried, it needs to be cooled quickly. During cooling, the dried organic fertilizer is continuously transported to the scattering box 1 using a conveyor belt or other conveying equipment. The first motor 5 is started to operate. The first motor 5 drives the rotating shaft 2 to rotate, and then drives the scattering blades 3 and the stirring rod 4 to rotate. The organic fertilizer entering the scattering box 1 is opened under the action of the scattering blades 3 and the stirring rod 4, thereby solving the clumping phenomenon. After that, the star-shaped discharge valve 13 is started to operate, and the organic fertilizer flows out along the discharge pipe 12 and falls on the guide plate 15, and falls on the vibration trough 7. The vibration motor 14 is started to operate synchronously. Under the action of the vibration motor 14 and the spring 8, the vibration trough 7 shakes the organic fertilizer evenly. At the same time, the industrial air cooler 16 is started to operate, and the cold air enters the first cold air pipe 9 and is ejected from the jet disk 10 to cool the organic fertilizer. At the same time, the induced draft fan 11 is started to operate. The induced draft fan 11 can extract the hot air in the primary cold box 6. After cooling The organic fertilizer falls into the feed nozzle 20 from the vibrating trough 7 and enters the auger conveyor 18. At the same time, the second motor 19 is started to run. The second motor 19 drives the auger shaft and the auger blades to rotate to transport the organic fertilizer. During the transportation process, the industrial air cooler 16 is kept running, and the cold air enters the second cold air pipe 21 and is ejected from the air nozzle 22. The ejected cold air cools the organic fertilizer again. The cooled organic fertilizer is discharged from the discharging nozzle 23. A receiving hopper or other conveying equipment can be connected below the discharging nozzle 23 to receive the material.
