Description

Technical Field

[0001] This utility model relates to the field of polar marine microbial fertilizer technology, specifically a polar marine microbial fertilizer spray dryer. Background Technology

[0002] Polar marine microbial fertilizer is a novel type of bio-fertilizer with polar marine bacteria as its core component. It possesses properties such as salt tolerance, acid and alkali resistance, high / low temperature resistance, and UV resistance, making it suitable for harsh environments such as high salinity, alkalinity, and drought. During the production process of polar marine microbial fertilizer, a dryer is needed to reduce the moisture content of the product. Spray dryers are commonly used for drying due to their high efficiency. In existing technology, patent publication number CN 207371125 U proposes a spray dryer, including a spray drying device and a dehumidification device. The spray drying device has a discharge port at the bottom. The dehumidification device is connected to the discharge port and used to dry the discharged material. While this can achieve the drying of polar marine microbial fertilizer, the single location of the hot air outlet in the drying chamber during the drying process can easily lead to uneven contact between the hot air and the atomized liquid, affecting the drying effect of the polar marine microbial fertilizer.

[0022] 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.

[0023] Please see Figure 1-7This embodiment provides a technical solution: a polar marine microbial fertilizer spray dryer, including a frame 1, which provides support for the spray drying components. The upper surface of the frame 1 is respectively provided with a drying cylinder 2, a filter cylinder 3, and a hot air box 5. Both the filter cylinder 3 and the hot air box 5 are connected to the drying cylinder 2. The top wall of the drying cylinder 2 is provided with an atomizing nozzle 4. The polar marine microbial fertilizer production liquid is atomized and sprayed out through the atomizing nozzle 4, and then dried by the hot air provided by the hot air box 5, evaporating the liquid into tiny particles. The dried tiny particles are carried by the airflow into the filter cylinder 3 for filtration, leaving the tiny particles inside the filter cylinder 3. The front surface of the frame 1 is provided with a microcontroller 10, whose input terminal is electrically connected to an external power source to control the start and stop of the entire device. The rear end of the frame 1 is provided with a liquid storage tank 12. The upper surface of the drying cylinder 2 is provided with a liquid inlet pipe 11, the upper end of which is connected to the liquid inlet of the atomizing nozzle 4, and the lower end of which extends into the lower part of the liquid storage tank 12. A high-pressure pump 13 is installed on the upper surface of the liquid storage tank 12. The high-pressure pump 13 is connected in series in the middle of the liquid inlet pipe 11. The input end of the high-pressure pump 13 is electrically connected to the output end of the microcontroller 10. The high-pressure pump 13 provides pressure for the atomization and spraying of the liquid produced by the polar marine microbial fertilizer. An air outlet pipe 15 is provided between the air outlet of the drying cylinder 2 and the air inlet of the filter cylinder 3. An exhaust pipe 16 is provided at the air outlet on the upper surface of the filter cylinder 3. A fan 14 is provided at the rear end of the frame 1. The air inlet of the fan 14 is connected to the exhaust pipe 16. The input terminal of the fan 14 is electrically connected to the output terminal of the microcontroller 10. The dried microparticles enter the filter cartridge 3 through the air outlet pipe 15 with the air. The filter bag inside the filter cartridge 3 filters the microparticles, keeping them inside the filter cartridge 3. The remaining air is discharged through the exhaust pipe 16. The fan 14 provides power for the airflow. The cover at the bottom of the filter cartridge 3 is removed periodically to clean and collect the microparticles inside the filter cartridge 3. The system also includes a drying mechanism 6.

[0024] Drying mechanism 6 includes a rotating ring 61, a hot air pipe 62, a hot air hole 63, and an air plate 64. The rotating rings 61 are rotatably connected to the inner arc surface of the drying cylinder 2. Each inner arc surface of the rotating ring 61 is provided with a hot air pipe 62. The lower end of the outer arc surface of the hot air pipe 62 is provided with a hot air hole 63. An air plate 64 is provided between two vertically adjacent rotating rings 61. The drying mechanism 6 also includes a fixed ring 65, an air inlet pipe 66, and a limiting sealing plate 68. The fixed rings 65 are respectively disposed on the inner arc surface of the drying cylinder 2. The rotating rings 61 are rotatably connected between the upper and lower surfaces of the fixed rings 65. The cross-section of each rotating ring 61 is U-shaped. Both the upper and lower ends of the inner arc surface of the fixed rings 65 are provided with... Limiting sealing plates 68 are respectively attached to the upper and lower inner walls of the rotating ring 61. Air inlets 66 are provided at the air inlets on the outer arc surface of the fixed ring 65, and the air inlets 66 are tangent to the outer arc surface of the fixed ring 65. The limiting sealing plates 68 are all ceramic plates, ensuring a seal between the rotating ring 61 and the limiting sealing plates 68, preventing hot air from leaking from the gap between the limiting sealing plates 68 and the rotating ring 61. The drying mechanism 6 also includes inclined plates 67, which are respectively disposed on the inner arc wall of the rotating ring 61. Hot air enters the space formed by the inner arc surface of the fixed ring 65 and the inner wall of the rotating ring 61 through the air inlets 66 and flows there, utilizing the flow of hot air to apply heat to the inclined plates 67. The thrust drives the rotating ring 61 and the fan plate 64 to rotate. Simultaneously, hot air enters the hot air duct 62 through the connecting hole in the inner arc wall of the rotating ring 61. The hot air flows along a planar spiral trajectory inside the hot air duct 62 and finally exits from the hot air hole 63. The hot air duct 62 also rotates with the rotating ring 61, changing the position of the hot air hole 63, making the hot air discharge more uniform in the horizontal direction. This guides the outlet position of the hot air, ensuring that the atomized liquid makes multiple contacts with the hot air discharged from the hot air hole 63 during its descent, exchanging heat and improving the overall drying effect. At the same time, the rotation of the fan plate 64 drives the atomized liquid and... The hot air moves horizontally, allowing for more comprehensive contact between the atomized liquid and the hot air, reducing the falling speed of the atomized liquid, increasing the heat exchange time, and making the drying of the atomized liquid more thorough. The hot air box 5 is equipped with a diversion pipe 7 at the air outlet, and the air inlet pipe 66 is connected to the diversion pipe 7. An electric fan 8 is installed inside the air duct of the hot air box 5, and electric heating tubes 9 are installed inside the hot air box 5. The input terminals of the electric heating tubes 9 and the electric fan 8 are electrically connected to the output terminal of the microcontroller 10. When the electric fan 8 and the electric heating tubes 9 are started, clean air from outside enters the hot air box 5 and is heated. The heated air is then dispersed into the air inlet pipe 66 through the diversion pipe 7.

[0025] The working principle of the polar marine microbial fertilizer spray dryer provided by this utility model is as follows: During the production process of polar marine microbial fertilizer, the single-chip microcomputer 10 starts the electric fan 8 and the electric heating tube 9, allowing clean external air to enter the hot air box 5 and be heated. The heated air is dispersed into the air inlet pipe 66 through the diverter pipe 7. The hot air flows through the air inlet pipe 66 into the space formed by the inner arc surface of the fixed ring 65 and the inner wall of the rotating ring 61. The flow of hot air applies a pushing force to the inclined plate 67, causing the rotating ring 61 and the air plate 64 to rotate. At the same time, the hot air enters the hot air pipe 62 through the connecting hole in the inner arc wall of the rotating ring 61. The hot air flows along the planar spiral trajectory inside the hot air pipe 62 and finally exits from the hot air hole 63. The hot air pipe 62 also rotates with the rotating ring 61, changing the position of the hot air hole 63, making the hot air discharge more uniform in the horizontal direction. Then, the high-pressure pump 13 is started, so that the polar marine microbial fertilizer production liquid stored in the storage tank 12 is atomized and sprayed out from the atomizing nozzle 4 through the liquid inlet pipe 11. During the falling process, the atomized liquid comes into full contact with the hot air discharged from the hot air hole 63 and exchanges heat, evaporating the liquid into tiny particles, thereby drying the polar marine microbial fertilizer production liquid. At the same time, the rotation of the air plate 64 drives the atomized liquid and hot air to rotate horizontally, so that the contact between the atomized liquid and hot air is more comprehensive. The centrifugal force generated by the rotation slows down the falling speed of the atomized liquid, increases the heat exchange time, and makes the drying of the atomized liquid more thorough. The dried tiny particles enter the filter cylinder 3 with the air through the air outlet pipe 15. The filter bag inside the filter cylinder 3 filters the tiny particles, leaving them inside the filter cylinder 3. The remaining air is discharged through the exhaust pipe 16.

[0026] It is worth noting that the microcontroller 10 disclosed in the above embodiments can be a PIC16F1823-I / P model microcontroller. The heating element 9, electric fan 8, high-pressure pump 13 and fan 14 can be freely configured according to the actual application scenario. The heating element 9 can be a 306 model heating element, the electric fan 8 can be a 6028 model flow guide fan, the high-pressure pump 13 can be an LC-2060 model high-pressure infusion pump, and the fan 14 can be a C4-73 model dust removal centrifugal induced draft fan. The microcontroller 10 controls the operation of the heating element 9, electric fan 8, high-pressure pump 13 and fan 14 using methods commonly used in the prior art.
