Description

Technical Field

[0001] This utility model relates to the field of fertilizer preparation technology, and in particular to a drying device for fertilizer preparation. Background Technology

[0002] Humic acid fertilizer is a type of organic fertilizer. Natural humic acid is formed from the decomposition of plant residues and is widely found in soil, river mud, and shallowly buried weathered coal, peat, and lignite. It contains elements such as carbon, hydrogen, oxygen, and nitrogen and has some fertilizer properties, but most of it is difficult to dissolve in water. However, if it is combined with substances such as potassium, sodium, and ammonium, dried, and ammonified, it can be easily absorbed by plants as nutrients.

[0003] However, traditional drying methods for humic acid fertilizers have many problems. On the one hand, when drying raw materials for micronutrient water-soluble fertilizers, uneven heating often leads to over-drying of some raw materials, resulting in nutrient loss, while some raw materials are under-dryed, affecting subsequent processing and product quality. On the other hand, piled-up raw materials are prone to clumping during the drying process, making it difficult to ensure uniform drying thickness. This not only reduces drying efficiency but also results in inconsistent drying effects, failing to meet the demand for efficient and high-quality production of micronutrient water-soluble fertilizers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for fertilizer preparation. It solves the technical problems that often occur when drying raw materials for micronutrient water-soluble fertilizers, where uneven heating leads to over-drying of some raw materials and loss of nutrients, while other raw materials are under-dryed, affecting subsequent processing and product quality. Furthermore, the accumulated raw materials are prone to clumping during the drying process, making it difficult to ensure uniform drying thickness. This not only reduces drying efficiency but also results in inconsistent drying effects, failing to meet the demand for efficient and high-quality production of micronutrient water-soluble fertilizers.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drying device for fertilizer preparation includes a base, a support fixedly installed on the upper end of the base, a drying tray fixedly installed on the upper end of the support, a heating wire fixedly installed on the lower end of the drying tray, an internal threaded ring threaded on the surface of the drying tray, and a material leveling mechanism fixedly installed on the upper end of the base.

[0007] The material leveling mechanism includes a drive motor, and a rotating shaft is installed on the output end of the drive motor. A cross groove is provided on the rotating shaft.

[0008] Preferably, a tilting rod is slidably installed inside the cross groove, and the tilting rod has an inner hole.

[0009] Preferably, a threaded ring is threaded onto the shaft, and a dovetail groove is formed on the side wall of the shaft.

[0010] Preferably, a first dovetail block is slidably installed inside the dovetail groove, the first dovetail block has a column groove inside, and a scraper is fixedly installed on the side wall of the first dovetail block.

[0011] Preferably, a sliding column is slidably installed inside the column groove, and a second dovetail block is fixedly installed at the lower end of the sliding column, the second dovetail block being slidably installed in the dovetail groove.

[0012] Preferably, a spring is fitted onto the sliding column, and the two ends of the spring are fixedly connected to the second dovetail block and the first dovetail block, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The drive motor will drive the rotating shaft to rotate, which will in turn drive the turning rod to rotate in the drying tray. As the turning rod rotates, the trace element water-soluble fertilizer raw materials inside the drying tray will slide along the inclined surface of the turning rod and be turned over. This allows the trace element water-soluble fertilizer raw materials to be continuously turned over during the heating process, which enhances the heat uniformity of the trace element water-soluble fertilizer raw materials and thus improves the drying effect.

[0015] Second, as the shaft rotates, the scraper will also rotate. Due to the spring force, the scraper will maintain a gap with the drying tray. When the scraper rotates, it can break up the accumulated trace element water-soluble fertilizer raw materials, so that the thickness is kept uniform, which further improves the uniformity of drying.

[0016] 3. After drying is complete, first unscrew the threaded ring and take out the turning rod. Then, after installing the threaded ring, continue to screw it downwards. At this time, the first dovetail block and the second dovetail block will approach each other, and the spring will be compressed. At this time, the scraper will fit against the drying tray. Then, remove the inner threaded ring from the drying tray. When the drive motor is started again, the scraper can scrape and clean the impurities generated during drying on the drying tray, making the equipment easy to clean during use.

[0023] This application provides a drying device for fertilizer preparation, which effectively solves the problem that uneven heating often leads to over-drying and nutrient loss in some raw materials during the drying of micronutrient water-soluble fertilizers, while under-drying affects subsequent processing and product quality. Furthermore, accumulated raw materials tend to clump together during the drying process, making it difficult to ensure uniform drying thickness, which not only reduces drying efficiency but also results in inconsistent drying effects, failing to meet the requirements for efficient and high-quality production of micronutrient water-soluble fertilizers. The device utilizes a drive motor to rotate a shaft, which in turn moves a tipping rod within the drying tray. As the rotating shaft rotates, the trace element water-soluble fertilizer raw materials inside the drying tray slide along the inclined surface of the rotating shaft and are turned over. This allows the trace element water-soluble fertilizer raw materials to be continuously turned over during the heating process, enhancing the heat uniformity of the trace element water-soluble fertilizer raw materials and thus improving the drying effect. As the rotating shaft rotates, the scraper will also rotate. Due to the spring force, the scraper will maintain a gap with the drying tray. When the scraper rotates, it can break up the accumulated trace element water-soluble fertilizer raw materials, making its thickness uniform and further improving the drying uniformity.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that when drying raw materials for trace element water-soluble fertilizer, uneven heating often leads to over-drying of some raw materials, resulting in nutrient loss, while some raw materials are under-dryed, affecting subsequent processing and product quality. Moreover, the accumulated raw materials are prone to clumping during the drying process, making it difficult to ensure uniform drying thickness. This not only reduces drying efficiency but also results in inconsistent drying effects, failing to meet the demand for efficient and high-quality production of trace element water-soluble fertilizer. The overall idea is as follows: A drying device for fertilizer preparation includes a base 11, a support 12 fixedly installed on the upper end of the base 11, a drying tray 13 fixedly installed on the upper end of the support 12, a heating wire 14 fixedly installed on the lower end of the drying tray 13, an internal threaded ring 15 threaded on the surface of the drying tray 13, and a material leveling mechanism fixedly installed on the upper end of the base 11.

[0026] The material equalization mechanism includes a drive motor 21, a rotating shaft 22 installed on the output end of the drive motor 21, a cross groove 23 on the rotating shaft 22, and a turning rod 24 slidably installed inside the cross groove 23. In use, the trace element water-soluble fertilizer raw material can be poured into the drying tray 13, and then the drying tray 13 is heated by the heating wire 14 set on the drying tray 13, thereby drying the trace element water-soluble fertilizer raw material. Then, the drive motor 21 is started, and the rotating shaft 22 is driven to rotate under the action of the drive motor 21. The rotating shaft 22 drives the turning rod 24 to rotate in the drying tray 13. Under the rotation of the turning rod 24, the trace element water-soluble fertilizer raw material inside the drying tray 13 will slide along the inclined surface of the turning rod 24 and be turned over. This allows the trace element water-soluble fertilizer raw material to be continuously turned over during the heating process, which enhances the heat uniformity of the trace element water-soluble fertilizer raw material and thus improves the drying effect.

[0027] The tipping rod 24 has an inner hole 25. A threaded ring 26 is threaded onto the rotating shaft 22. A dovetail groove 27 is formed on the side wall of the rotating shaft 22. A first dovetail block 28 is slidably installed inside the dovetail groove 27. A column groove 29 is formed inside the first dovetail block 28. A scraper 31 is fixedly installed on the side wall of the first dovetail block 28. A sliding column 32 is slidably installed inside the column groove 29. A second dovetail block 33 is fixedly installed at the lower end of the sliding column 32. The second dovetail block 33 is slidably installed in the dovetail groove 27. A spring 34 is sleeved on the sliding column 32. The two ends of the spring 34 are fixedly connected to the second dovetail block 33 and the first dovetail block 28, respectively. In use, the first dovetail block 28 and the second dovetail block 33 can be inserted into the dovetail groove 27. Then, the threaded ring 26 is rotated on the rotating shaft 22 to complete the fixation. At this time, the rotating shaft 22 As the scraper 31 rotates, it will also rotate. Due to the elastic force of the spring 34, the scraper 31 will maintain a gap with the drying tray 13. When the scraper 31 rotates, it can break up the accumulated trace element water-soluble fertilizer raw materials, so that the thickness is uniform and the drying uniformity is further improved. After drying, the threaded ring 26 can be unscrewed first, the turning rod 24 can be taken out, and then the threaded ring 26 can be installed and screwed down continuously. At this time, the first dovetail block 28 and the second dovetail block 33 will approach each other, the spring 34 will be compressed, and the scraper 31 will fit with the drying tray 13. At this time, the inner threaded ring 15 can be removed from the drying tray 13. When the drive motor 21 is started, the scraper 31 can scrape and clean the impurities generated during drying on the drying tray 13, making the equipment easy to clean during use.

[0028] To address the problems existing in the prior art, this utility model provides a drying device for fertilizer preparation. Driven by a motor 21, a rotating shaft 22 rotates, which in turn drives a turning rod 24 to rotate within the drying tray 13. As the turning rod 24 rotates, the trace element water-soluble fertilizer raw materials inside the drying tray 13 slide along the inclined surface of the turning rod 24, thus being turned over. This allows the trace element water-soluble fertilizer raw materials to be continuously turned over during heating, enhancing the uniformity of heating and improving the drying effect. The scraper 31 also rotates with the rotating shaft 22. Due to the elastic force of the spring 34, a gap is maintained between the scraper 31 and the drying tray 13. As the scraper 31 rotates, it can break up the accumulated trace element water-soluble fertilizer raw materials, maintaining a uniform thickness and further improving the uniformity of drying.

[0029] in:

[0030] Base 11: As the basic support structure of the entire drying device, it is fixedly installed on the ground or other working platform to provide a stable installation foundation for the bracket 12, drying tray 13 and material leveling mechanism and other components above, ensuring that the device will not shift or shake during operation and guaranteeing the stability of the equipment operation.

[0031] Support 12: Supports the drying tray 13 at a certain height, which facilitates operation and cooperation with components such as the drive motor 21 below. At the same time, it provides stable suspension support for the drying tray 13 to prevent damage to the drying tray 13 due to uneven force during operation.

[0032] Drying tray 13: Used directly to hold raw materials for water-soluble fertilizers containing trace elements;

[0033] Heating wire 14: After being powered on, it generates heat to heat the drying tray 13, thereby transferring the heat to the trace element water-soluble fertilizer raw materials in the tray, realizing the drying treatment of the raw materials, and is the main heat source provider in the drying process.

[0034] Internal threaded ring 15: After drying, it is removed from the drying tray 13 to facilitate subsequent cleaning of impurities from the drying tray 13 using the scraper 31;

[0035] Drive motor 21: As the power source of the material leveling mechanism, after starting, the drive motor 21 outputs torque, drives the rotating shaft 22 to rotate, and then drives the turning rod 24 and scraper 31 connected to the rotating shaft 22 to operate, realizing the turning, dispersing and cleaning of the raw materials in the drying tray 13, providing power support for the entire material leveling and cleaning process.

[0036] Rotating shaft 22: One end is connected to the output end of the drive motor 21 and rotates under the drive of the drive motor 21. The rotating shaft 22 is a key shaft part that transmits power and connects various moving parts.

[0037] Tilting rod 24: Installed in the cross groove 23, it rotates in the drying tray 13 when the rotating shaft 22 rotates. The tilting rod 24 has an inclined surface. During the rotation, the trace element water-soluble fertilizer raw material inside the drying tray 13 will slide along the inclined surface of the tilting rod 24, thereby realizing the turning operation of the raw material. This allows the raw material to be continuously turned during the heating process, greatly enhancing the heating uniformity of the raw material and improving the drying effect. The tilting rod 24 is a key component for realizing the turning of the raw material and ensuring the uniformity of drying.

[0038] Threaded ring 26: Used to fix the tipping rod 24 and scraper 31;

[0039] Dovetail groove 27: serves as a guide when adjusting the position of scraper 31;

[0040] First dovetail block 28: is a key component that connects the rotating shaft 22 and the scraper 31 and enables the scraper 31 to be adjusted and rotated.

[0041] Scraper 31: It is an important component for improving drying uniformity and removing impurities;

[0042] The second dovetail block 33 is slidably installed in the dovetail groove 27 to realize different working states of the scraper 31 (such as breaking up raw materials and cleaning impurities), and together with the first dovetail block 28, it ensures the stability of the scraper 31 during the working process.

[0043] Spring 34: It plays a role in adjusting the distance between scraper 31 and drying tray 13 and in buffering, ensuring the flexibility and stability of scraper 31 in operation.

[0044] Working principle:

[0045] The first step is to pour the trace element water-soluble fertilizer raw material into the drying tray 13. Then, the drying tray 13 is heated by the heating wire 14 set on the drying tray 13 to dry the trace element water-soluble fertilizer raw material. Next, the drive motor 21 is started. Under the action of the drive motor 21, the rotating shaft 22 is driven to rotate. The rotating shaft 22 drives the turning rod 24 to rotate in the drying tray 13. Under the rotation of the turning rod 24, the trace element water-soluble fertilizer raw material inside the drying tray 13 will slide along the inclined surface of the turning rod 24 and be turned over. This allows the trace element water-soluble fertilizer raw material to be continuously turned over during the heating process, which enhances the heat uniformity of the trace element water-soluble fertilizer raw material and thus improves the drying effect.

[0046] In the second step, when using it, the first dovetail block 28 and the second dovetail block 33 can be inserted into the dovetail groove 27. Then, the threaded ring 26 is rotated on the rotating shaft 22 to fix it. At this time, the scraper 31 will also rotate under the rotation of the rotating shaft 22. Due to the elastic force of the spring 34, the scraper 31 will maintain a gap with the drying tray 13. When the scraper 31 rotates, it can break up the piled trace element water-soluble fertilizer raw materials, so that its thickness is uniform and the drying uniformity is further improved.

[0047] Third, after drying is complete, first unscrew the threaded ring 26 and remove the turning rod 24. Then, after installing the threaded ring 26, continue to screw it downwards. At this time, the first dovetail block 28 and the second dovetail block 33 will approach each other, and the spring 34 will be compressed. At this time, the scraper 31 will fit against the drying tray 13. Then, remove the inner threaded ring 15 from the drying tray 13. When the drive motor 21 is started, the scraper 31 can scrape and clean the impurities generated during drying on the drying tray 13, making the equipment easy to clean during use.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
