Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-4 This utility model discloses a fertilizer drying device for fertilizer production, including a tank 1, which serves as a container for drying operations. A heating sleeve 2 is fixedly sleeved on its outer end. The heating sleeve 2 can be heated by electric heating or steam heating to externally heat the material inside the tank 1.

[0025] A top cover 3 is detachably installed on the upper end of the tank body 1. The top cover 3 is connected to the tank body 1 by a flange or clips, which facilitates opening for internal maintenance or cleaning. A multi-purpose stirring assembly 5 is installed in the middle of the top cover 3. This assembly is the core component of this device and has the functions of stirring, introducing heating gas and cleaning liquid.

[0026] Specifically, the multi-purpose stirring assembly 5 includes a hollow tubular shaft 51 rotatably connected to the upper cover 3. A bearing can be installed at the connection point between the shaft and the upper cover 3 to ensure smooth rotation. The lower end of the shaft 51 extends into the tank body 1 and is fixedly connected to multiple stirring tubes 52. The stirring tubes 52 communicate with the interior of the shaft 51, forming a gas or liquid flow channel. Multiple end pipes 53 are installed at the outer ends of the stirring tubes 52. The end pipes 53 communicate with the interior of the stirring tubes 52 and have open openings, used to discharge heating gas or cleaning liquid into the material.

[0027] In this embodiment, the multiple stirring tubes 52 are divided into upper and lower layers, with the included angle between the stirring tubes 52 in the same layer being 120°. This distribution method allows the stirring range to cover most of the area inside the tank 1, avoiding dead zones in the stirring. The multiple end tubes 53 are all inclinedly distributed on the upper and lower sides of the stirring tubes 52, which can not only enhance the agitation effect on the material, but also allow the heating gas or cleaning liquid to diffuse more evenly.

[0028] The end pipe 53 includes a pipe body 531, one end of which is fixedly connected to the stirring pipe 52, and the other end is threadedly connected to a threaded interface 532. A filter screen 533 is provided inside the opening of the threaded interface 532. The filter screen 533 can prevent fertilizer particles from entering the pipe body 531 and causing blockage, while the threaded interface 532 facilitates disassembly, cleaning, or replacement of the filter screen 533.

[0029] The outer end of the tube shaft 51 is equipped with a connector 54. The connector 54 is a rotary joint that can be connected to external gas supply equipment (such as a hot air blower) and liquid supply equipment (such as a cleaning water pump) to ensure that gas or liquid can still be stably introduced when the tube shaft 51 rotates.

[0030] A drive assembly 4 is provided on the upper surface of the cover 3 to drive the multi-purpose stirring assembly 5 to rotate. Specifically, the drive assembly 4 includes a transmission box 41, with a first pulley 43 and a second pulley 44 rotatably connected inside the transmission box 41. A transmission belt is sleeved between the first pulley 43 and the second pulley 44. A motor 42 is fixedly installed on the upper surface of the transmission box 41. The output shaft of the motor 42 is connected to the second pulley 44 and drives it to rotate. The first pulley 43 is fixedly sleeved on the outer end of the tube shaft 51, and the tube shaft 51 and the entire stirring assembly are driven to rotate through belt transmission.

[0031] A feeding pipe 6 is fixedly installed on one side of the upper end face of the top cover 3. The feeding pipe 6 is used to feed the fertilizer material to be dried into the tank 1. The upper end cover is equipped with a sealing cover 7. During the drying operation, the sealing cover 7 is closed to ensure the airtightness of the tank 1. A discharge port 9 is installed at the middle of the lower end of the tank 1. The discharge port 9 is equipped with a valve for discharging the material after drying is completed.

[0032] In addition, an exhaust pipe 8 is fixedly connected to one side of the upper end face of the cover 3. The exhaust pipe 8 is connected to the inside of the tank 1 and is used to discharge water vapor or waste gas generated during the drying process to prevent the pressure inside the tank 1 from being too high. The exhaust pipe 8 can be connected to a waste gas treatment device to avoid polluting the environment.

[0033] It should be noted that details not mentioned in this embodiment, such as the specific control method of the heating jacket 2 and the model of the motor 42, can adopt mature solutions in the existing technology, and will not be elaborated here.

[0034] The working principle and usage process of this utility model are as follows: During the drying operation, open the sealing cover 7, put the fertilizer to be dried into the feeding pipe 6, and close the sealing cover 7. Start the motor 42, which drives the multi-purpose stirring component 5 to rotate through the drive component 4. The stirring pipe 52 and the end pipe 53 stir the material.

[0035] Simultaneously, the heating jacket 2 is activated for external heating, and heating gas is introduced into the tube shaft 51 through the connector 54 via an external gas supply device. The heating gas is discharged from the end pipe 53 through the stirring pipe 52, directly contacting the material for heating. This combined external heating achieves dual drying, improving efficiency. The water vapor generated during the drying process is discharged through the exhaust pipe 8. After drying is completed, heating and gas supply are stopped, and the discharge port 9 is opened to discharge the fertilizer.

[0036] To clean tank 1, close outlet 9 and introduce cleaning fluid through connector 54. The cleaning fluid is sprayed out through end pipe 53. At the same time, multi-purpose stirring component 5 rotates to clean various areas inside tank 1. The cleaning wastewater is discharged from outlet 9.

[0037] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
