Description

Technical Field

[0001] This utility model relates to the field of adsorption dryer technology, specifically a blower dryer for fertilizer production. Background Technology

[0002] The adsorption dryer utilizes advanced chemical technology. Its principle is to filter out saturated water vapor in compressed air by using a special molecular sieve for gas purification, which is based on the difference in volume between water and air molecules. Water molecules can be easily adsorbed into the molecular sieve particles, and then the molecular sieve can be restored using a regeneration method.

[0003] Traditional dryers mostly use a single drying chamber design. When the desiccant becomes saturated with moisture, the machine needs to be stopped to replace or regenerate it, which leads to interruption of the drying process. In addition, the moisture absorption capacity of a single desiccant decreases after long-term use, which can easily cause uneven drying of fertilizers and large fluctuations in efficiency. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a blower-type dryer for fertilizer production, which solves the problems of traditional dryers that mostly use a single drying chamber design, requiring the machine to be stopped for replacement or regeneration when the desiccant becomes saturated with moisture, leading to interruptions in the drying process. Furthermore, the desiccant's moisture absorption capacity decreases after long-term use, easily causing uneven fertilizer drying and large efficiency fluctuations.

[0023] like Figures 1-4 As shown, this utility model embodiment provides a blower-type dryer for fertilizer production, including a base plate 1, a drying chamber 2 connected to the upper surface of the base plate 1, a fan 3 connected to one side of the upper surface of the base plate 1 in the drying chamber 2, the output end of the fan 3 connected to the drying chamber 2, a first pipe 4 connected to the input end of the fan 3, a first drying chamber 5 connected to the end of the first pipe 4 away from the fan 3, a second pipe 6 connected to the end of the first drying chamber 5 away from the first pipe 4, a filter box 7 connected to the end of the second pipe 6 away from the first drying chamber 5, an air inlet pipe 8 connected to the end of the filter box 7 away from the second pipe 6, and a stirring assembly 9 provided inside the drying chamber 2.

[0024] Furthermore, a second drying box 10 is connected to the upper surface of the base plate 1 on one side of the first drying box 5. A third pipe 11 is connected between the second drying box 10 and the filter box 7, and a fourth pipe 12 is connected between the second drying box 10 and the first pipe 4.

[0025] Furthermore, the upper surfaces of the first drying chamber 5 and the second drying chamber 10 are respectively connected to the fifth pipe 13 and the sixth pipe 14, and the upper surface of the fifth pipe 13 and the sixth pipe 14 is connected to the seventh pipe 15. The end of the seventh pipe 15 away from the fifth pipe 13 and the sixth pipe 14 is connected to the interior of the drying chamber 2.

[0026] Furthermore, the second pipe 6, the third pipe 11, the fifth pipe 13, and the sixth pipe 14 are connected to a first valve 16, a second valve 17, a third valve 18, and a fourth valve 19 for controlling the switch.

[0027] Furthermore, a heating chamber 20 is provided at the connection between the fan 3 and the drying box 2.

[0028] Furthermore, the stirring assembly 9 includes a rotating shaft 91 rotatably connected to the inner cavity of the drying chamber 2, a stirring rod 92 connected to the outer circumference of the rotating shaft 91, a motor 93 connected to the upper surface of the drying chamber 2, and the output end of the motor 93 connected to the rotating shaft 91.

[0029] Furthermore, a feed inlet 21 is connected to one side of the upper surface of the drying chamber 2, and a sealing cap 22 is threadedly connected to the upper surface of the feed inlet 21. A discharge outlet 23 is connected to one side of the drying chamber 2, and a built-in valve is installed in the discharge outlet 23.

[0030] Furthermore, the drying chamber contains a desiccant for adsorbing moisture in the air, and the filter chamber 7 contains a filter plate for filtering air impurities.

[0031] Working principle:

[0032] In operation, first open the sealing cover 22 of the feed inlet 21 on the upper surface of the drying chamber 2, and put the fertilizer raw materials to be dried into the drying chamber 2 through the feed inlet 21. Then tighten the sealing cover 22 to ensure the airtightness of the drying chamber 2. Next, open the first valve 16, and simultaneously close the second valve 17, the third valve 18, and the fourth valve 19, and then start the fan 3. Outside air enters the filter box 7 through the air inlet pipe 8, and impurities in the air are intercepted and filtered by the filter plate in the filter box 7. The filtered air enters the first drying chamber 5 through the second pipe 6, and the moisture in the air is absorbed by the desiccant in the first drying chamber 5. The dried air enters the fan 3 through the first pipe 4, and is then transported to the heating chamber 20. After being heated in the heating chamber 20, it enters the interior of the drying chamber 2. At this time, the motor 93 is started, and the motor 93 drives the rotating shaft 91 to rotate. The rotating shaft 91 drives the stirring rod 92 to rotate synchronously, stirring the fertilizer in the drying chamber 2, making the fertilizer heated more evenly and improving the drying effect. Once the fertilizer is dried, open the valve at the discharge port 23 to discharge the dried fertilizer.

[0033] When the equipment has been used for a period of time and the desiccant in the first drying chamber 5 absorbs too much moisture, affecting the drying effect, the process can be switched to the second drying chamber 10. The specific operation is as follows: Close the first valve 16 and the fourth valve 19, open the second valve 17 and the third valve 18, and start the fan 3. Outside air enters the filter chamber 7 through the air inlet pipe 8 to filter impurities, and then enters the second drying chamber 10 through the third pipe 11. The moisture in the air is absorbed by the desiccant in the second drying chamber 10. The dried air then enters the fan 3 through the fourth pipe 12 and the first pipe 4, and is heated by the heating chamber 20 before being sent into the drying chamber 2. Simultaneously, the motor 93 is started, and the rotating shaft 91 drives the stirring rod 92 to stir the fertilizer, ensuring uniform drying. After drying, the discharge port 23 valve is opened to discharge the fertilizer. During this process, the hot air in the drying chamber 2 enters the first drying chamber 5 through the seventh pipe 15 and the fifth pipe 13 to dry and regenerate the desiccant inside for subsequent recycling.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
