Description

Technical Field

[0001] This utility model belongs to the technical field of organic fertilizer drying equipment, specifically relating to a drying device for organic fertilizer production. Background Technology

[0002] Organic fertilizer not only provides comprehensive nutrition for crops, but also has a long-lasting effect. It can increase and renew soil organic matter, promote the reproduction of microorganisms, and improve the physical and chemical properties and biological activity of the soil. It is a major nutrient for green food production. However, the drying equipment on the market today has a relatively simple structure and function. The contact time between organic fertilizer and hot air is short, resulting in incomplete drying of organic fertilizer and affecting its quality.

[0003] For example, in Chinese utility model patent CN206572890U, entitled "A Drying Device for Organic Fertilizer Production," although the aforementioned technology effectively prevents organic fertilizer from adhering to the inner surface of the inner drum and improves drying efficiency by providing protrusions on the inner surface of the inner drum at equal intervals, this structural design leads to insufficient contact between the organic fertilizer and hot air during the drying process, resulting in a long drying time. Furthermore, it may cause uneven heating of the organic fertilizer during the drying process, leading to incomplete drying. Therefore, a drying device for organic fertilizer production is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for organic fertilizer production that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A drying device for organic fertilizer production includes a box body with a feed inlet fixedly connected to the top of the box body. A drying component is installed inside the box body. Rotating shafts that are rotatably connected to the box body are fixedly connected to both sides of the drying component. A first servo motor is fixedly installed on one side of the box body. The output shaft of the first servo motor rotatably passes through the box body and the rotating shaft and is fixedly connected to a roller shaft on one side of the drying component.

[0007] As a further optimization of this utility model, the drying assembly includes a drying cylinder fixedly connected to one end of two rotating shafts, a hollow shaft rotatably connected inside the drying cylinder, one end of the hollow shaft rotatably passing through the drying cylinder and the housing and rotatably connected to an adapter fixedly connected to the housing, a hot air pipe fixedly connected to one side of the adapter, a plurality of air outlet holes opened on the surface of the hollow shaft, and a plurality of crushing blades provided on the surface of the hollow shaft.

[0008] As a further optimization of this utility model, a second servo motor is fixedly installed on one side of the housing, and the output end of the second servo motor and one end of the hollow shaft are both fixedly fitted with mutually meshing gears.

[0009] As a further optimization of this utility model, a purification pipe is fixedly connected to one side of the drying cylinder, and an activated carbon plate is fixedly connected inside the purification pipe.

[0010] As a further optimization of this utility model, a discharge trough is provided at the bottom of the drying cylinder, the discharge trough is provided with a discharge door, a hinge is installed between the discharge door and the drying cylinder, and a receiving box is provided inside the box.

[0011] As a further optimization of this utility model, a bracket is fixedly provided on the surface of the adapter, and one end of the bracket is fixedly installed with the housing.

[0012] The beneficial effects of this utility model are as follows: This utility model has a drying cylinder, a hollow shaft, an air outlet, and crushing blades installed inside the housing. When organic fertilizer enters the drying cylinder, the first servo motor drives the drying cylinder to rotate, causing the organic fertilizer to rotate inside the drying cylinder. At this time, the second servo motor rotates in the opposite direction. Since the hollow shaft and the second servo motor are meshed by gears, they drive the hollow shaft and the crushing blades to rotate in opposite directions simultaneously. Hot air from the hot air pipe enters the hollow shaft, and the hot air is released into the drying cylinder through the air outlet on the surface of the hollow shaft. This allows the organic fertilizer to come into contact with the hot air in all directions when rotating, which can improve the drying efficiency and uniformity of the organic fertilizer. The crushing blades crush the organic fertilizer that is prone to clumping, causing the internal moisture of the clumped organic fertilizer to evaporate. The crushed cross-section increases the contact area between the organic fertilizer and the hot air, improving the drying effect. The hot airflow from the air outlet can also play a certain role in purging, reducing the amount of organic fertilizer adhering to the surface of the hollow shaft and the crushing blades.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a drying device for organic fertilizer production includes a housing 1. The top of the housing 1 is fixedly connected to an inlet 2. During use, the inlet 2 serves as the channel for organic fertilizer to enter the equipment, allowing the organic fertilizer to accurately enter the predetermined position. The housing 1 is equipped with a door, which effectively seals the housing 1 when closed, reducing the entry of cold air from the outside and the loss of hot air from the inside, thus helping to maintain a stable temperature environment inside the housing 1 and ensuring the drying effect. A discharge trough 12 is opened at the bottom of the drying cylinder 301, and a discharge door 13 is provided on the discharge trough 12. A hinge 14 is installed between the discharge door 13 and the drying cylinder 301. A receiving box 7 is provided inside the housing 1. During use, the organic fertilizer in the drying cylinder 301 is discharged through the discharge trough 12 and the discharge door 13. The receiving box 7 is placed below the drying cylinder 301 to receive the organic fertilizer discharged from the drying cylinder 301, realizing the centralized collection of materials for subsequent unified processing or transportation.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a drying assembly 3 is installed inside the housing 1. Rotating shafts 4, which are rotatably connected to the housing 1, are fixedly connected to both sides of the drying assembly 3. During use, the rotating shafts 4 provide stable support for the drying cylinder 301, ensuring it does not shake or shift during operation. A first servo motor 5 is fixedly installed on one side of the housing 1. The output shaft of the first servo motor 5 rotates through the housing 1 and the rotating shafts 4 and is fixedly connected to a roller 6 on one side of the drying assembly 3. During use, the first servo motor 5 is the power source for the rotation of the entire drying assembly 3, providing stable adjustment power. The output shaft of the first servo motor 5 rotates through the housing 1 and the rotating shafts 4 and is fixedly connected to a roller 6 on one side of the drying assembly 3. Roller 6 is fixedly connected. When the motor starts, the output shaft drives roller 6 to rotate. Since roller 6 is fixed to drying assembly 3, and drying assembly 3 is rotatably connected to housing 1 through rotating shaft 4, the entire drying assembly 3 will rotate around the axis of rotating shaft 4. A second servo motor 8 is fixedly installed on one side of housing 1. The output end of the second servo motor 8 and one end of the hollow shaft 302 are both fixedly fitted with meshing gears 9. In use, the second servo motor 8 serves as a power source. After starting, the output gear 9 meshes with the gear 9 on the hollow shaft 302, transmitting the power of the second servo motor 8 to the hollow shaft 302, so that the hollow shaft 302 can rotate according to the drive of the second servo motor 8.

[0025] like Figure 3 , Figure 6 and Figure 7As shown, the interior of the housing 1 is equipped with a drying assembly 3. The drying assembly 3 includes a drying cylinder 301 fixedly connected to one end of two rotating shafts 4. During use, the drying cylinder 301 can hold organic fertilizer and dry it. A hollow shaft 302 is rotatably connected inside the drying cylinder 301. One end of the hollow shaft 302 rotatably passes through the drying cylinder 301 and the housing 1 and is rotatably connected to an adapter 10 fixedly connected to the housing 1. During use, the hollow shaft 302 and the adapter 10 provide support for the drying cylinder 301. A bracket 17 is fixedly mounted on the surface of the adapter 10, and one end of the bracket 17 is fixedly installed to the housing 1. The bracket 17 connects the adapter 10 to the housing 1, providing additional support for the adapter 10 and the hollow shaft 302. It can share the force on the hollow shaft 302 during rotation, preventing the adapter 10 from shaking or shifting. The hollow shaft 302 rotates in the opposite direction to the drying drum 301. A hot air pipe 11 is fixedly connected to one side of the adapter 10. During use, one end of the hot air pipe 11 has a hot air source device (not shown in the figure), which connects to the hollow shaft 302 via the adapter 10, ensuring that hot air can accurately and efficiently enter the drying drum 301 to provide the necessary heat for drying the organic fertilizer. Several air outlets 303 are opened on the surface of the hollow shaft 302, and several crushing blades 3 are provided on the surface of the hollow shaft 302. 04. During use, several air outlets 303 and crushing blades 304 are evenly distributed on the surface of the hollow shaft 302. The air outlets 303 allow hot air delivered by the hot air pipe 11 to pass through the interior of the hollow shaft 302 and be released directly into the organic fertilizer from the central area of ​​the drying drum 301. This avoids the uneven heating problem caused by hot air only entering from the drum wall, ensuring that the material is in full contact with the hot air, significantly improving drying efficiency and uniformity. The airflow from the air outlets 303 also has a certain purging effect, reducing the adhesion of material to the surfaces of the hollow shaft 302 and crushing blades 304. During the drying process, organic fertilizer is prone to caking or agglomeration, making it difficult for internal moisture to evaporate. When the crushing blades 304 rotate with the hollow shaft 302, they can effectively purify the soil. Breaking up these clumps increases the surface area of ​​the organic fertilizer, allowing hot air to fully contact the fertilizer and improving the drying effect. For materials with larger initial particle sizes, the crushing blade 304 can break them into smaller particles, further improving the drying effect. A purification pipe 15 is fixedly connected to one side of the drying cylinder 301, and an activated carbon plate 16 is fixedly connected inside the purification pipe 15. During use, it provides an exhaust channel for the humid and hot gas and waste gas generated inside the drying cylinder 301, allowing the gas inside the drying cylinder 301 to flow out smoothly and maintaining stable gas pressure inside the drying cylinder 301. The activated carbon plate 16 inside the purification pipe 15 has a strong adsorption capacity, which can adsorb various odor substances generated during the drying process, making the emitted gas purer.

[0026] It should be noted that, in the operation of this drying device for organic fertilizer production, when the organic fertilizer needs to be dried, the operator first starts the first servo motor 5, which drives the roller 6 to rotate. Since the roller 6 is connected to the drying cylinder 301, the drying cylinder 301 rotates, and then the discharge chute 12 at the bottom of the drying cylinder 301 rotates to be below the inlet 2. Then, the discharge door 13 is opened, and the organic fertilizer is poured into the drying cylinder 301 through the inlet 2 and the discharge chute 12. Then, the discharge door 13 and the chamber door are closed. During the drying process, the first servo motor 5 operates, driving the roller 6... 6. The drying drum 301 rotates, causing the organic fertilizer to tumble continuously inside the drum, forming a motion trajectory. At this time, the second servo motor 8 is activated. The gear 9 installed at the output end of the second servo motor 8 precisely meshes with the gear 9 on the hollow shaft 302. Through the gear 9 transmission mechanism, the rotational force of the second servo motor 8 is transmitted to the hollow shaft 302. The hollow shaft 302 passes through the center of the drying drum 301, and its surface is evenly distributed with crushing blades 304 and air vents 303. When the hollow shaft 302 rotates inside the drying drum 301, on the one hand, the rotational speed of the crushing blades 304 cuts the clumps of organic fertilizer inside the drum. Crushing breaks large pieces of material into smaller ones, increasing the contact area between the organic fertilizer and the hot air, thus accelerating moisture evaporation. Meanwhile, hot air is delivered through hot air duct 11 to adapter 10, and then introduced into the hollow shaft 302. As the hollow shaft 302 rotates, the internal hot air is released radially into the drying cylinder 301 through the air outlet 303, forming a uniform hot air field. This hot air comes into full contact with the constantly tumbling organic fertilizer, carrying away moisture and achieving the drying purpose. Simultaneously, the hot air blown from the air outlet 303 also cleans the hollow shaft 302 and the crushing blades 304. The organic fertilizer adhering to the surface is blown away to prevent material accumulation from affecting the normal operation of the equipment and the drying effect. When drying is completed, the operator uses the first servo motor 5 to rotate the discharge chute 12 of the drying cylinder 301 to the downward position. Then, the first servo motor 5 and the second servo motor 8 are turned off to stop the rotation of the drying cylinder 301 and the hollow shaft 302. At this time, the operator opens the box door and the discharge door 13. The dried organic fertilizer automatically falls into the receiving box 7 under the action of gravity. The operator takes out the receiving box 7 and transfers the dried organic fertilizer to the subsequent processing stage to complete the entire drying process.

[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
