Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feed and fertilizer processing, specifically to a high-efficiency drying device for feed and fertilizer processing. Background Technology
[0002] Feed and fertilizer processing refers to the process of converting raw materials into feed and fertilizer products through certain processes. To ensure product quality, drying is necessary. However, existing drying equipment for feed and fertilizer processing has certain defects. During use, the current drying equipment has poor ventilation, and the heat generated during drying cannot be discharged from the drying chamber in time, which can easily cause the dryer to malfunction and reduce processing efficiency.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202122322291.4, application date 2021-09-25) provides a high-efficiency dryer for organic fertilizer processing. The combination of support legs and anti-slip seats ensures stable placement of the device, improving its stability. The combination of the feed hopper and feed pipe facilitates material pouring by workers, preventing spillage. The dryer body enables rapid drying of fertilizers. The combination of a cooling fan and ventilation holes ensures timely heat dissipation and ventilation inside the drying chamber, preventing overheating and damage to the dryer body, thus improving the processing efficiency of organic fertilizers. The combination of a sliding groove and a slider facilitates pushing and pulling of the receiving box by workers, improving material collection efficiency.
[0004] While existing technologies can provide timely ventilation, the overall energy consumption is excessive during operation because the drying chamber is cooled and ventilated through cooling fans and vents. This not only affects production costs but also increases the maintenance burden on the equipment. Furthermore, the drying process relies solely on unidirectional gas flow, resulting in limited contact area and time between the gas and the fertilizer. Consequently, the drying efficiency of the device is low, leading to poor overall drying results.
[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing high-efficiency drying devices for feed and fertilizer processing. Therefore, we propose that a high-efficiency drying device for feed and fertilizer processing can effectively solve these problems. Utility Model Content
[0006] The purpose of this utility model is to provide a high-efficiency drying device for feed and fertilizer processing, in order to solve the problems mentioned in the background art. Currently, the drying box is cooled and ventilated by heat dissipation fans and ventilation holes, which consumes too much energy, affects production costs, increases the maintenance burden of the equipment, and dries only by unidirectional gas flow, resulting in a small contact area and time between the gas and fertilizer, thus the drying efficiency of the device is low and the overall drying effect is poor.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency drying device for feed and fertilizer processing, comprising a base, a drying cylinder mounted on the base, a hot air blower for conveying hot air mounted on the base, a feed hopper mounted on one side of the drying cylinder, a motor mounted on the other side of the drying cylinder, an agitator connected to the output end of the motor via a rotating shaft, the agitator being located inside the drying cylinder, a first sleeve sleeved on the outside of the rotating shaft, the first sleeve being connected to a conveying pipe, a conveying groove being formed inside the rotating shaft, the inner cavity of the first sleeve being connected to the conveying groove, and a through groove for conveying hot air being formed on the outside of the rotating shaft.
[0008] Preferably, the feed hopper is connected to the side end of the drying cylinder via a feed pipe, and the output end of the hot air blower is connected to the inner cavity of the drying cylinder via a conveying pipe.
[0009] Preferably, a second sleeve is fitted on the outer side of the rotating shaft, and a scraper adapted to the inner wall of the drying cylinder is connected to the outer side of the second sleeve through a rotating rod.
[0010] Preferably, the second sleeve is threaded onto the outside of the positive and negative screws, which are mounted on the rotating shaft.
[0011] Preferably, the positive and negative screws are provided with a first through hole that communicates with the conveying groove, and the first through hole is connected to the inner cavity of the second sleeve.
[0012] Preferably, the outer side of the rotating rod is provided with a second through hole for conveying hot air, and the second through hole is connected to the conveying groove through the inner cavity of the rotating rod.
[0013] Preferably, the top of the drying cylinder is provided with a transmission pipe for conveying humid and hot air, and an auxiliary sleeve is connected to the end of the transmission pipe.
[0014] Preferably, the auxiliary sleeve is fitted outside the feed hopper, and a dehumidification box for moisture absorption is installed on the transmission pipe.
[0015] Compared with the prior art, the beneficial effects of this utility model are: This high-efficiency drying device for feed and fertilizer processing drives the stirring element to rotate inside the drying cylinder through a rotating shaft. The overall structure is simple, reducing the problem of increased costs due to high energy consumption. Hot air is directly delivered to the working area of the stirring element, further improving the drying effect and reducing the problem of reduced drying efficiency due to unidirectional flow. The specific details are as follows:
[0016] (1) The agitator is driven to rotate inside the drying cylinder by the rotating shaft. The overall structure is simple, which reduces the problem of high energy consumption leading to increased costs. Hot air is directly delivered to the working area of the agitator, which further improves the drying effect and reduces the problem of reduced drying efficiency caused by unidirectional flow.
[0017] (2) The second sleeve on the outside of the rotating shaft drives the rotating rod to rotate, so that the scraper at the end of the rotating rod stirs the feed and fertilizer inside the drying cylinder. The scraper can not only stir the feed and fertilizer, but also scrape the material near the cylinder wall to prevent the material from sticking to the cylinder wall and ensure the thoroughness of drying.
[0018] (3) The rotating shaft drives the positive and negative screws to rotate, making it easy to move the position of the rotating rod and the scraper. By adjusting the position of the rotating rod and the scraper, the material in different positions of the drying cylinder can be stirred and turned over, ensuring that the material in the entire drying cylinder can be fully processed and improving the uniformity of drying.
[0019] (4) Hot air is delivered to the inside of the rotating rod through the first through hole on the positive and negative screws, and is output through the second through hole on the side of the rotating rod. The hot air diffuses inside the material, accelerates the evaporation of moisture from inside the material, and further improves the drying efficiency.
[0020] (5) The dehumidified hot air is transported through the transmission pipeline to the auxiliary sleeve outside the feed hopper. The hot air can be recycled to reduce energy consumption and achieve efficient use of resources. The hot air transported to the auxiliary sleeve can preheat the material in the feed hopper, reducing the time and energy required for subsequent drying. Attached Figure Description

[0029] 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.
[0030] Example 1: In this example, hot air is directly delivered to the working area of the mixing component 9, allowing the hot air to come into more thorough contact with the feed and fertilizer, further improving the drying effect and reducing the problem of reduced drying efficiency caused by unidirectional flow. Figures 1-6The technical solution shown includes a base 1, a drying cylinder 2 mounted on the base 1, a hot air blower 5 for conveying hot air mounted on the base 1, a feed hopper 3 mounted on one side of the drying cylinder 2, and a motor 7 mounted on the other side of the drying cylinder 2. The output end of the motor 7 is connected to a stirring element 9 via a rotating shaft 8. The stirring element 9 is located inside the drying cylinder 2. A first sleeve 10 is fitted outside the rotating shaft 8 and is connected to a conveying pipe 6. A conveying groove 11 is formed inside the rotating shaft 8. The inner cavity of the machine base 1 is connected to the conveying trough 11. A through groove 12 for conveying hot air is opened on the outside of the rotating shaft 8. The feed hopper 3 is connected to the side end of the drying cylinder 2 through the feed pipe 4. The output end of the hot air blower 5 is connected to the inner cavity of the drying cylinder 2 through the conveying pipe 6. The feed fertilizer to be dried is poured into the feed hopper 3. The opening of the feed hopper 3 facilitates the quick and smooth entry of the feed fertilizer, improving the feeding efficiency. At this time, the feed fertilizer is conveyed to the inside of the drying cylinder 2 of the machine base 1 through the feed pipe 4. At this time, the hot air blower 5 is turned on. The hot air blower 5 delivers hot air into the drying cylinder 2 through the conveying pipe 6, facilitating the drying of the feed and fertilizer inside the drying cylinder 2. The hot air blower 5 provides stable and appropriately heated hot air, quickly removing moisture from the feed and fertilizer, greatly shortening the drying time and improving drying efficiency. The motor 7 is turned on, and its output drives the stirring component 9 to rotate inside the drying cylinder 2 through the rotating shaft 8. The stirring component 9 ensures that the feed and fertilizer are fully agitated during the drying process, ensuring uniform heating of all parts and avoiding uneven drying. The overall structure is simple, reducing the problem of increased costs due to high energy consumption. The hot air blower 5 also introduces hot air into the first sleeve 10 through the conveying pipe 6. At this time, the hot air is conveyed through the conveying groove 11 of the rotating shaft 8 and blown out through the through groove 12 opened on the side of the rotating shaft 8. The hot air is directly delivered to the working area of the stirring component 9, allowing the hot air to have more full contact with the feed and fertilizer, further improving the drying effect and reducing the problem of reduced drying efficiency caused by unidirectional flow.
[0031] Example 2: In this example, during rotation, the scraper 15 not only stirs the feed and fertilizer but also scrapes the material near the drum wall, preventing it from sticking to the drum wall and ensuring thorough drying. Specifically, as follows... Figures 4-7As shown, a second sleeve 13 is fitted on the outer side of the rotating shaft 8. A scraper 15 adapted to the inner wall of the drying cylinder 2 is connected to the outer side of the second sleeve 13 via a rotating rod 14. The second sleeve 13 is threaded to the outer side of the positive and negative screws 16, which are mounted on the rotating shaft 8. When the rotating shaft 8 rotates, the second sleeve 13 on its outer side drives the rotating rod 14 to rotate, causing the scraper 15 at the end of the rotating rod 14 to stir the feed and fertilizer inside the drying cylinder 2. During the rotation process, the scraper 15 can not only stir the feed and fertilizer but also... The fertilizer is stirred and scraped to prevent the material from sticking to the drum wall, ensuring thorough drying. The rotating shaft 8 drives the positive and negative screws 16 to rotate, causing the second sleeve 13 to move outside the positive and negative screws 16. This allows the rotating rod 14 and scraper 15 to be moved easily. By adjusting the position of the rotating rod 14 and scraper 15, the material in different positions of the drying drum 2 can be stirred and turned, ensuring that the material in the entire drying drum 2 is fully processed and improving the uniformity of drying.
[0032] Example 3: In this example, the dehumidified hot air is transported through the transmission pipe 19 to the auxiliary sleeve 21 outside the feed hopper 3. The hot air can be recycled, reducing energy consumption and achieving efficient resource utilization. Specifically, as follows... Figure 1 and Figures 4-7 As shown, the positive and negative screws 16 have a first through hole 17 communicating with the conveying groove 11. The first through hole 17 is connected to the inner cavity of the second sleeve 13. The outer side of the rotating rod 14 has a second through hole 18 for conveying hot air. The second through hole 18 is connected to the conveying groove 11 through the inner cavity of the rotating rod 14. The top of the drying cylinder 2 is provided with a transmission pipe 19 for conveying humid hot air. The end of the transmission pipe 19 is connected to an auxiliary sleeve 21, which is sleeved on the outside of the feed hopper 3. A dehumidification box 20 for absorbing moisture is installed on the transmission pipe 19. Hot air is conveyed to the inside of the rotating rod 14 through the first through hole 17 on the positive and negative screws 16, and then conveyed through the second through hole 18 on the side of the rotating rod 14. Hot air diffuses within the material, accelerating moisture evaporation and further improving drying efficiency. The hot air inside the drying cylinder 2, after contacting the feed fertilizer, is transported through the transmission pipe 19 and dehumidified by the dehumidification box 20. The dehumidified hot air is then transported through the transmission pipe 19 to the auxiliary sleeve 21 outside the feed hopper 3. This hot air can be recycled, reducing energy consumption and achieving efficient resource utilization. The hot air transported to the auxiliary sleeve 21 can preheat the material in the feed hopper 3, reducing the time and energy required for subsequent drying and further improving the efficiency of the entire drying process.
