[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional concentrated organic fertilizers. They can also be classified by source as farmyard manure and chemical fertilizers. Based on the amount of nutrients they contain, they are classified as complete fertilizers and incomplete fertilizers; based on the characteristics of nutrient supply, they are classified as direct fertilizers and indirect fertilizers; and based on their composition, they are classified as nitrogen fertilizers, potassium fertilizers, micronutrient fertilizers, and rare earth element fertilizers.
[0003] Even after processing, fertilizers still contain a large amount of moisture and water vapor. Furthermore, the raw materials are uneven in size and quite moist, making them prone to clumping. After production, fertilizers need to be dried to prevent mold and spoilage. Existing drying equipment uses a dryer to heat and dehumidify the fertilizer. This method is ineffective for drying fertilizers that have accumulated inside, has a slow drying speed, and consumes a lot of energy, reducing fertilizer production efficiency. Therefore, improving existing fertilizer drying equipment and designing a new type of drying device to address these technical shortcomings and improve the overall practicality of fertilizer drying equipment is particularly important.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example
[0021] Please see Figures 1-3 This utility model provides a technical solution:
[0022] A drying device for fertilizer production includes a drying cylinder 1. A rotating roller 2 is rotatably connected inside the drying cylinder 1. A spiral stirring blade 202 is fixedly connected to the outside of the rotating roller 2 and inside the drying cylinder 1. Multiple sets of equally spaced air outlets 201 are opened in the gaps between the stirring blades 202 and the outside of the rotating roller 2. Bases 8 are rotatably connected to both ends of the drying cylinder 1. The two sets of bases 8 are designed to face each other. A motor 5 is fixedly connected to the top of one set of bases 8, and a hot air blower 6 is fixedly connected to the top of the other set of bases 8. A rotating shovel 3 is provided on the outside of the rotating roller 2 and inside the drying cylinder 1. The drive end of the motor 5 extends into the interior of the drying cylinder 1 and is fixedly connected to the rotating roller 2 and the rotating shovel 3. The hot air blower 6 is fixedly connected to one end of the drying cylinder 1 and inside the base 8. There is an air supply pipe 601. The end of the air supply pipe 601 away from the hot air blower 6 extends into the interior of the rotating roller 2 and is rotatably connected to the rotating roller 2. When the fertilizer production drying device is put into use, the power is turned on, and the hot air blower 6 into the rotating roller 2 through the air supply pipe 601. The hot air is evenly sprayed onto the fertilizer from multiple sets of air outlets 201, thereby drying the fertilizer. At the same time, the drive end of the motor 5 rotates, thereby driving the rotating roller 2 to rotate, which in turn drives the stirring blade 202 and the rotating shovel 3 to rotate, thereby continuously shoveling up the fertilizer in the stirring drying cylinder 1, breaking up the fertilizer that is stuck together, increasing the gaps between the fertilizer, which not only speeds up the drying speed but also makes the fertilizer dry evenly without any leakage, thus improving the fertilizer production efficiency. In addition, the rotating shovel 3 can scrape the fertilizer off the inner wall of the drying cylinder 1, saving raw materials.
[0023] Furthermore, a clean air chamber 4 is fixedly connected to the top of the hot air blower 6. The clean air chamber 4 is equipped with an activated carbon filter bag inside, and an exhaust port 403 is opened on the top of the clean air chamber 4. A connecting pipe 401 is fixedly connected to the clean air chamber 4 near the drying cylinder 1 and inside the base 8. A filter screen 402 is fixedly connected to the inside of the drying cylinder 1 and near the end of the connecting pipe 401. The filter screen 402 and the connecting pipe 401 are designed to be compatible. When the drying device for fertilizer production is put into use, the water vapor and other gases from the fertilizer inside the drying cylinder 1 after being heated enter the connecting pipe 401 through the filter screen 402 and then enter the clean air chamber 4. After being absorbed and filtered by the activated carbon filter bag in the clean air chamber 4, the harmful gases are discharged, reducing the contact time between workers and odors and protecting the health of workers.
[0024] The drying cylinder 1 has a feed trough 101 on its outer side and a slide trough 102 inside the feed trough 101. A slide door 103 is slidably connected inside the slide trough 102. Both the drying cylinder 1 and the slide door 103 are equipped with a heat insulation layer 7. When the drying device for fertilizer production is put into use, closing the slide door 103 accelerates the heating speed inside the drying cylinder 1. The heat insulation layer 7 prevents the heat inside the drying cylinder 1 from escaping, prolongs the service life, and saves energy.
[0025] Secondly, handles 104 are fixedly connected to the outer side of the sliding door 103 and the outer side of the drying cylinder 1, near the feed trough 101. The handles 104 are made of silicone. When the drying device for fertilizer production is put into use, the silicone handles 104 will not burn the workers. After the fertilizer is dried, the feeding cylinder is placed at the bottom of the drying cylinder 1. The workers hold the handles 104 on the outside of the drying cylinder 1 and rotate the drying cylinder 1 so that the feed trough 101 is aligned with the feeding cylinder. Then the sliding door 103 is opened to facilitate material retrieval and improve work efficiency.
[0026] In this embodiment, the specific implementation scenario is as follows: In actual use, when the fertilizer production drying device is put into use, the sliding door 103 is opened, the fertilizer to be dried is placed inside the feed trough 101, the sliding door 103 is closed, the power is turned on, and the hot air blower 6 blows hot air into the rotating roller 2 through the air supply pipe 601. The hot air is evenly sprayed onto the fertilizer from multiple sets of air outlets 201, thereby drying the fertilizer. At the same time, the drive end of the motor 5 rotates, thereby driving the rotating roller 2 to rotate, which in turn drives the stirring blade 202 and the rotating shovel 3 to rotate, thereby continuously shoveling up the fertilizer in the stirring drying cylinder 1, breaking up the fertilizer that is stuck together, increasing the gaps between the fertilizer, which not only speeds up the drying speed but also makes the fertilizer dry evenly without any leakage, thus improving the fertilizer production efficiency. In addition, the rotating shovel 3 can scrape the fertilizer off the inner wall of the drying cylinder 1, saving raw materials. The water vapor and other gases from the fertilizer inside the drying cylinder 1, after being heated, pass through the filter screen 402 into the connecting pipe 401 and then into the clean air chamber 4. After being absorbed and filtered by the activated carbon filter bag in the clean air chamber 4 to remove harmful gases, the gases are discharged, reducing the contact time between workers and odors and protecting their health. The heat insulation layer 7 prevents the heat inside the drying cylinder 1 from escaping, prolonging the service life and saving energy. After the fertilizer is dried, the feeding cylinder is placed at the bottom of the drying cylinder 1. The worker holds the handle 104 on the outside of the drying cylinder 1 and rotates the drying cylinder 1. The silicone handle 104 will not burn the worker. The feeding trough 101 is aligned with the feeding cylinder, and then the sliding door 103 is opened for easy material removal, improving work efficiency. Compared with existing fertilizer production drying devices, this utility model improves the overall practicality of fertilizer production drying devices through its design.
