Description

Technical Field

[0001] This application relates to the technical field of fertilizer production equipment, and in particular to a coating device for fertilizer production. Background Technology

[0002] In the development of modern agriculture, the quality and performance of fertilizers directly affect the yield and quality of crops. Fertilizer coating technology, by coating the surface of fertilizer granules with a specific material, can effectively control the release rate of fertilizer nutrients, prevent fertilizer from absorbing moisture and clumping, and enhance the wear resistance of fertilizer granules.

[0003] Existing fertilizer coating equipment suffers from several shortcomings in process control. Specifically, it lacks precision in controlling parameters such as hot air temperature and spray volume, exhibits a lack of adaptive adjustment capabilities, leads to unstable product quality, inadequate waste gas treatment, and low resource recovery rates. These shortcomings can result in uneven coating thickness and inconsistent coating quality in fertilizer granules. Regarding the aforementioned technologies, the applicant believes that there is a defect of unstable coating quality. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a coating device for fertilizer production.

[0005] This application provides a coating equipment for fertilizer production, which adopts the following technical solution: A coating device for fertilizer production includes a fluidized bed mechanism, a spraying mechanism, an air inlet mechanism, an air outlet mechanism, and a frame. The fluidized bed mechanism is mounted on the frame and is detachably connected to the frame. The spraying mechanism is mounted on one side of the fluidized bed mechanism, with one end detachably connected to the fluidized bed mechanism and its base detachably connected to the frame. The air inlet mechanism is mounted at the bottom of the fluidized bed mechanism, with one end detachably connected to the fluidized bed mechanism and the other end detachably connected to the frame. The air outlet mechanism is mounted at the top of the fluidized bed mechanism, with one end detachably connected to the fluidized bed mechanism and the other end detachably connected to the frame.

[0006] By adopting the above technical solution, the fluidized bed mechanism, spraying mechanism, air inlet mechanism, and exhaust mechanism are all detachably connected to the frame and to each mechanism. The air inlet mechanism introduces air from the bottom to fluidize the fertilizer granules in the fluidized bed. The spraying mechanism sprays the coating liquid onto the granules from the side. The exhaust mechanism discharges waste gas from the top. In the fertilizer production process, different fertilizer varieties and production requirements may require different process parameters and equipment layouts. Adjusting the air volume and air velocity of the air inlet mechanism allows the granules to reach the optimal fluidization state in the fluidized bed. For different coating materials and coating requirements, adjusting the spraying angle, spray volume, and other parameters of the spraying mechanism ensures stable coating quality.

[0007] Preferably, the fluidized bed mechanism includes a chamber, a gas distribution plate, and a vibration unblocking mechanism. The chamber is mounted on a frame and is detachably connected to the frame. The gas distribution plate is mounted at the bottom of the chamber and is detachably connected to the chamber. The vibration unblocking mechanism is mounted on one side of the bottom of the chamber and is detachably connected to the chamber.

[0008] By adopting the above technical solution, the chamber, gas distribution plate and vibration unblocking mechanism are all detachably connected. The gas distribution plate is installed at the bottom of the chamber, which can evenly distribute the gas delivered by the air intake mechanism to the entire bed cross section, so that the fertilizer particles can obtain a stable and uniform fluidization state. The vibration unblocking mechanism effectively prevents material accumulation by vibrating periodically or in real time.

[0009] Preferably, a feed inlet is provided on one side of the chamber, a discharge outlet is provided on the other side of the chamber, an air inlet is provided at the bottom of the chamber, a plurality of blower mechanisms are provided at the bottom of the air inlet, the blower mechanisms are detachably connected to the bottom of the air inlet, an air outlet is provided at the top of the chamber, and a spray nozzle is provided on the chamber above the feed inlet.

[0010] Preferably, the spraying mechanism includes multiple sprayers and a liquid supply mechanism. The sprayers are mounted on the liquid supply mechanism and are detachably connected to the liquid supply mechanism. The liquid supply mechanism is mounted on a frame and is detachably connected to the frame. The sprayers are placed inside the cavity through spray nozzles.

[0011] By adopting the above technical solution, the sprayer and the liquid supply mechanism, as well as the liquid supply mechanism and the frame, are detachably connected. The layout of multiple sprayers can cover a larger spraying area, ensuring that the coating material is evenly distributed on the surface of the fertilizer granules. By optimizing the position and angle of the sprayer, the consistency and quality stability of the coating are improved. The liquid supply mechanism, as the liquid delivery hub of the sprayer, can provide stable pressure and flow.

[0012] Preferably, the liquid supply mechanism includes a liquid storage tank, a liquid delivery pipeline, and a high-pressure pump. The liquid storage tank is mounted on a frame on one side of the spray nozzle of the cabin. The high-pressure pump is installed between the liquid storage tank and the liquid delivery pipeline. The high-pressure pump is detachably connected to both the liquid storage tank and the liquid delivery pipeline. The sprayer is installed on the liquid delivery pipeline and is detachably connected to the liquid delivery pipeline.

[0013] By adopting the above technical solution, the high-pressure pump, the storage tank, and the delivery pipeline are all detachably connected. The high-pressure pump is installed between the storage tank and the delivery pipeline, which can provide stable pressure and ensure that the coating material is delivered to each sprayer quickly and evenly.

[0014] Preferably, the air intake mechanism includes a hot air mechanism and an air intake pipe. The air intake is a pipe with one inlet and multiple outlets. The hot air mechanism is mounted on the frame and is detachably connected to the frame. The single outlet of the air intake pipe is detachably connected to the hot air mechanism, and the multiple outlets of the air intake pipe are detachably connected to the air intake.

[0015] By adopting the above technical solution, the hot air mechanism, the air inlet pipe, the frame, and the air inlet are detachably connected. The air inlet pipe adopts a pipe body design with one inlet and multiple outlets, which can evenly distribute hot air to multiple areas of the fluidized bed, avoiding excessively strong or weak local airflow, thereby achieving a more stable particle fluidization state. The hot air mechanism is installed on the frame and connected to the single outlet of the air inlet pipe, ensuring that the heated air can be directly and efficiently delivered to the air inlet.

[0016] Preferably, the hot air mechanism includes a heating system, a first fan, and a dehumidification mechanism. The dehumidification mechanism is installed at one end of the heating system near the fluidized bed mechanism and is detachably connected to the heating system. The first fan is installed at the other end of the heating system and is detachably connected to the heating system.

[0017] By adopting the above technical solution, the heating system, the first fan, and the dehumidification mechanism are all detachably connected. The dehumidification mechanism is installed at one end of the heating system near the fluidized bed mechanism, which can remove the moisture in the hot air before it enters the fluidized bed, thus avoiding the humid air from affecting the fluidization effect and coating quality of the fertilizer particles. The first fan is installed at the other end of the heating system, which can provide sufficient air pressure and air volume to ensure that the hot air passes through the heating system and the dehumidification mechanism quickly and is evenly delivered to the fluidized bed mechanism.

[0018] Preferably, the exhaust mechanism includes an exhaust duct, a second fan, an air purification device, and an air volume regulating device. The air volume regulating device is installed between the air outlet and one end of the exhaust duct, and the air volume regulating device is detachably connected to both the air outlet and one end of the exhaust duct. The second fan is installed at the other end of the exhaust duct, and the second fan is detachably connected to the exhaust duct. The air purification device is installed on the exhaust duct after the second fan, and the air purification device is detachably connected to the exhaust duct.

[0019] By adopting the above technical solution, the air volume regulating device, the second fan, the air purification device, and the exhaust pipe are all detachably connected. The air volume regulating device is installed between the air outlet and one end of the exhaust pipe, which can accurately adjust the exhaust air volume according to actual production needs. The air purification device is installed on the exhaust pipe after the second fan, which can purify the exhaust gas and effectively remove pollutants such as dust, odors, and harmful gases.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The chamber, gas distribution plate, and vibration unblocking mechanism are all detachably connected. The gas distribution plate is installed at the bottom of the chamber and can evenly distribute the gas delivered by the air intake mechanism to the entire bed cross section, so that the fertilizer particles can obtain a stable and uniform fluidization state. The vibration unblocking mechanism effectively prevents material accumulation by vibrating periodically or in real time.

[0021] The hot air mechanism, air inlet pipe, frame, and air inlet are detachably connected. The air inlet adopts a pipe design with one inlet and multiple outlets, which can evenly distribute hot air to multiple areas of the fluidized bed, avoiding excessively strong or weak local airflow, thereby achieving a more stable particle fluidization state. The hot air mechanism is installed on the frame and connected to a single outlet of the air inlet pipe to ensure that the heated air can be directly and efficiently delivered to the air inlet.

[0027] Fertilizer enters the chamber 11 through the inlet 111. An infusion pipe 222 is installed on the spray nozzle 115 above. A sprayer 21 is installed on the infusion pipe 222. The sprayer 21 and the infusion pipe 222 are placed inside the chamber 11. The other end of the infusion pipe 222 is installed on the storage tank 221 through a high-pressure pump 223. The high-pressure pump 223 is detachably connected to the infusion pipe 222 and the storage tank 221. The storage tank 221 is installed on the frame 5 and is threadedly connected to the frame 5. The high-pressure pump 223 maintains a stable pressure so that the coating agent is evenly sprayed onto the fertilizer in the chamber 11 through the sprayer 21.

[0028] The first fan 312 is installed on the side away from the heating system 311 of the fluidized bed mechanism 1, and the dehumidification mechanism 313 is installed on the side closer to the heating system 311 of the fluidized bed mechanism 1. The heating system 311, the first fan 312, and the dehumidification mechanism 313 are all detachably connected. When the first fan 312 is working, the hot air from the heating system 311 is sent into the dehumidification mechanism 313 to remove moisture and enter the air inlet pipe 32. The inlet of the air inlet pipe 32 is detachably connected to the dehumidification mechanism 313, and the outlet of the air inlet pipe 32 has multiple evenly distributed openings. The air inlet pipe 32 is detachably connected to the air inlet 113. The hot air is brought into the chamber 11 by the blower mechanism 14 installed at the bottom of the air inlet 113. The air inlet inside the chamber 11... A gas distribution plate 12 is installed at position 113, which, together with multiple air inlets 32, ensures stable and uniform airflow. This allows the fertilizer to be fluidized and uniformly coated before flowing to the outlet 112. An air outlet 114 is provided at the top of the chamber 11. An airflow regulating device 44 is installed between the air outlet 114 and the exhaust pipe 41.

The second fan 42 is connected to the air purification device 43 through another section of the exhaust pipe 41.

[0029] The working principle of a coating device for fertilizer production in this application is as follows: A first blower 312 is installed on the side away from the heating system 311 of the fluidized bed mechanism 1, and a dehumidification mechanism 313 is installed on the side close to the heating system 311 of the fluidized bed mechanism 1. The blower blows the hot air generated by the heating system 311 into the dehumidification mechanism 313, which removes excess water from the hot air. The hot air enters the air inlet 113 through the air inlet pipe 32. An upward blowing mechanism 14 is installed at the bottom of the air inlet 113 to send the hot air into the chamber 11. A gas distribution plate 12 is installed between the chamber 11 and the air inlet 113 to blow the gas evenly and stably onto the fertilizer to fluidize it. A liquid delivery pipe 222 is installed above the feed inlet 111 of the chamber 11. One end of the infusion pipeline 222 is placed inside the chamber 11. Multiple sprayers 21 are installed on the infusion pipeline 222 placed inside the chamber 11. The other end of the infusion pipeline 222 is connected to the storage tank 221 through the high-pressure pump 223. The coating agent is sprayed onto the fluidized fertilizer inside the chamber 11 through the infusion pipeline 222 and the sprayers 21, so that the fertilizer forms a coating and is sent into the discharge port 112. An air volume regulating device 44 is installed between the air outlet 114 at the top of the chamber 11 and one end of the exhaust pipe 41. A second fan 42 is installed at the other end of the exhaust pipe 41. The second fan 42 extracts the exhaust gas from the chamber 11. The second fan 42 is connected to the air volume regulating device 44 through a section of exhaust pipe 41 so that the exhaust gas enters the air volume regulating device 44.
