Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment for fertilizer production, specifically a drying equipment for fertilizer production. Background Technology

[0002] Chemical fertilizers are fertilizers containing one or more nutrients needed for crop growth, produced using chemical or physical methods. The raw materials are mixed and then fed into a steam granulator, where they are agglomerated into granules by steam. These granules are then dried in a dryer. The drying process is essential for fertilizer production, requiring a drying device. While a wide variety of drying devices are available on the market today, generally meeting most needs, certain problems remain: First, it's difficult to adjust the feed rate, leading to fertilizer accumulation. Second, drying devices rarely allow for stirring, crushing, or scraping of the fertilizer, reducing their practicality. Third, few drying devices incorporate hot air circulation, resulting in wasted heat.

[0003] A search revealed existing technology (application number: CN202120060671.2), which describes "a drying device for fertilizer production." This utility model includes a device body, a feed box fixed at the top of the device body, moving plates on the surface of the moving troughs, a drive motor mounted on one side of the device body surface of the feed box, a filter screen mounted on the inner wall of the device body below the stirring roller, protective covers fixed on the inner walls of both sides of the device body, a discharge port on one side of the device body, and a collection box fixed on the surface of the device body away from the discharge port.

[0004] However, while existing technologies have avoided fertilizer accumulation during the use of drying devices, they still have some shortcomings: uneven drying. Utility Model Content

[0029] 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.

[0030] Reference Figures 1-5 This utility model provides a drying device for fertilizer production, comprising: a box assembly 3, the box assembly 3 including a drying box 32, a vibration structure 21 provided on the drying box 32, a top plate 216 fixedly provided above the vibration structure 21, the top plate 216 being slidably connected to sliding grooves 215 fixedly provided on both sides of the inner wall of the drying box 32 via a connecting assembly; a turning assembly 2 provided on the drying box 32, the turning assembly 2 including a second motor 22, the second motor 22 being fixedly provided on one side of the outer wall of the drying box 32, and the output end of the second motor 22 being fixedly connected to a second turning shaft 25, the second turning shaft 25 being rotatably connected through the drying box 32, and a first turning shaft 24 being rotatably connected through the outer wall of the drying box 32, the first turning shaft 24 being symmetrical to the second turning shaft 25, and both the first turning shaft 24 and the second turning shaft 25 being provided inside the drying box 32, with belts 23 sleeved on the first turning shaft 24 and the second turning shaft 25, the belts 23 being provided on the outside of the drying box 32.

[0031] In this embodiment, the drying component, the turning component, and the box component constitute the fertilizer production drying device involved in this application, realizing a fertilizer production drying device. Any fertilizer that needs to be dried in fertilizer production can use this equipment. This application does not limit the specific fertilizer category.

[0032] In this embodiment, motor 22 is started, driving the second turning shaft 25 to rotate, which in turn drives the first turning shaft 24 to rotate via belt 23, thereby turning the fertilizer in the drying box 32.

[0033] In this embodiment, the vibration structure 21 loosens the fertilizer material in the drying chamber 32 by vibrating up and down, preventing the material from clumping and increasing the contact area between the material and the air, thereby improving the drying efficiency.

[0034] It should be noted that the drying oven is made of stainless steel, which has excellent corrosion resistance and can resist the erosion of humid environments, chemicals and fertilizer particles. It is not easy to rust with long-term use, reducing the frequency of equipment maintenance and replacement. In addition, stainless steel can remain stable in high-temperature environments and will not deform or be damaged due to high temperatures, ensuring the reliability of the drying oven in the high-temperature drying process.

[0035] Specifically, the vibration structure 21 includes a motor 211, which is fixedly installed on one side of the outer wall of the drying chamber 32. The output end of the motor 211 is fixedly connected to a rotating shaft 212, which is located in the center of the bottom of the drying chamber 32. The end of the rotating shaft 212 away from the motor 211 is rotatably connected to the drying chamber 32.

[0036] In this embodiment, the output of motor 211 drives the rotating shaft 212 to rotate, thereby enabling the vibration structure to operate.

[0037] Specifically, cams 213 are fixedly connected through both ends of the rotating shaft 212, and push rods 214 are rotatably connected to the cams 213. The push rods 214 are all fixedly set at the bottom of the top plate 216.

[0038] In a preferred embodiment, the rotation of the rotating shaft 212 drives the cam 213 to rotate, and the cam 213 pushes the push rod 214 to move up and down, thereby causing the top plate 216 to vibrate, so that the fertilizer placed on the top plate 216 vibrates and prevents it from clumping.

[0039] Specifically, connecting components are fixedly installed at the four corners of the top plate 216. The connecting components include telescopic rods 217. The bottom end of the telescopic rods 217 is fixedly installed above the top plate 216, and a connecting plate 219 is fixedly installed at the top end of the top plate 216. A spring 218 is installed on the telescopic rods 217. One end of the spring 218 is fixedly connected to the top plate 216, and the other end of the spring 218 is fixedly connected to the connecting plate 219.

[0040] It should be noted that when the top plate 216 vibrates, the telescopic rod 217 extends and retracts, the spring 218 buffers the vibration of the top plate 216, and the connecting plate 219 slides to connect the sliding grooves 215 on both sides of the drying oven 32, ensuring that the top plate 216 vibrates stably, while ensuring that the top plate 216 slides normally inside the drying oven 32.

[0041] Specifically, a fixed frame 312 is fixedly installed on the outer wall of the drying chamber 32 on the side away from the motor 211 for discharging fertilizer, and a baffle 311 is slidably connected through the fixed frame 312.

[0042] As a preferred implementation, pushing the baffle 311 controls the opening and closing of the fixed frame 312, thereby controlling the discharge of fertilizer, and the discharge operation can be carried out as needed.

[0043] Specifically, the drying chamber 32 is provided with a drying component 1, which includes a drying hood 13. The drying hood 13 is fixedly connected to the top of the drying chamber 32, and several sets of guide plates 11 are fixedly provided below the drying hood 13. A heating tube 12 is fixedly provided below the top of the drying hood 13, and a fan 14 is fixedly provided on the outer side of the top of the drying hood 13.

[0044] It should be noted that the heating tube 12 generates heat to provide the hot air required for drying, the fan 14 operates to blow the hot air into the drying chamber 32, and the guide plate 11 guides the flow direction of the hot air so that the hot air is evenly distributed in the drying chamber 32 to dry the fertilizer.

[0045] Specifically, a feed inlet 33 is provided on one side of the drying hood 13. The feed inlet 33 is fixedly installed on the top of the drying box 32 for feeding fertilizer. An air outlet 15 is fixedly installed on the top of the drying box 32 away from the feed inlet 33.

[0046] In this embodiment, fertilizer enters the drying chamber 32 through the feed inlet 33, and the hot and humid air generated during the drying process is discharged through the air outlet 15 to ensure the normal circulation of the drying environment.

[0047] In use, when drying fertilizer, the user starts motor 22. The output of motor 22 drives the belt 23 pulley on the first turning shaft 24 to rotate. The belt 23 transmits power to the belt 23 pulley on the second turning shaft 25, so the first turning shaft 24 and the second turning shaft 25 will rotate along with the belt 23 pulley, thus turning the fertilizer on the top plate 216. At this time, the user pours the fertilizer to be dried into the drying chamber 32 through the feed inlet 33 and starts fan 14. Fan 14 distributes the heat of the heating tube 12 evenly and carries the hot air around the heating rod to other parts of the drying chamber 32, thus making the entire chamber airtight. As the temperature in the space rises, the user starts motor 211. The output of motor 211 drives the rotating shaft 212 to rotate, and the two sets of cams 213 on the rotating shaft 212 rotate. When the protruding end on the cam 213 rotates to the top, it lifts the push rod 214, and then the top plate 216 rises along the slide groove 215. The rising top plate 216 compresses the spring 218, and the spring 218 stores force. When the cam 213 rotates to the other end, the push rod 214 does not contact the cam 213. With the cooperation of the spring 218, the top plate 216 vibrates up and down, and the fertilizer on the top plate 216 vibrates. Hot air will pass through the gaps between the fertilizers, making the drying more thorough.

[0048] This utility model discloses a drying device for fertilizer production. A motor drives a rotating shaft, causing the fertilizer on the top plate to continuously tumble. Simultaneously, hot air is evenly distributed within the drying chamber by a fan, ensuring uniform heating of the fertilizer during the drying process and improving drying efficiency and effectiveness. The motor-driven cam and top rod, combined with the elasticity of a spring, cause the top plate to oscillate up and down, allowing hot air to penetrate the gaps in the fertilizer particles, further enhancing the drying effect. The fan carries the hot air around the heating element to other parts of the drying chamber, ensuring a uniform temperature rise throughout the sealed space and preventing localized overheating or uneven drying, thus ensuring the stability and consistency of the drying process.

[0049] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0050] 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.
