Description

Technical Field

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

[0002] Drying is a crucial step in the production of bio-fertilizers. Bio-fertilizers contain a large number of beneficial microorganisms, and the activity of these microorganisms directly affects the fertilizer's effectiveness. Therefore, low-temperature drying is necessary to avoid damaging these beneficial microorganisms with high temperatures. Low-temperature drying removes moisture from the bio-fertilizer, bringing it to a suitable moisture content for storage and transportation, while maximizing the preservation of the probiotics' activity, thus ensuring the quality and efficacy of the bio-fertilizer.

[0003] However, a common problem currently encountered in the drying process of bio-fertilizers is that moist bio-fertilizers tend to clump together, and these clumps are difficult to separate. This is because bio-fertilizers contain a certain amount of sticky substances, which, in a moist state, cause the particles to adhere to each other, forming large clumps. Existing drying equipment often struggles to fully disperse these clumps, resulting in difficulty in evaporating moisture from the clumps and low drying efficiency. Furthermore, the presence of clumps can cause uneven drying, and some bio-fertilizers may lose their activity due to prolonged exposure to high temperatures, affecting the quality of the bio-fertilizer. Therefore, there is an urgent need for a low-temperature drying device that can effectively solve the problem of clumping in moist bio-fertilizers, thereby improving drying efficiency and the quality of the bio-fertilizer. Utility Model Content

[0004] The present invention aims to provide a low-temperature drying device for bio-fertilizers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A low-temperature drying device for bio-fertilizer, wherein the drying box is connected to a feed pipe, the drying box is connected to a drying component, the drying box is connected to an equipment box, the inner wall of the equipment box is connected to a motor, the output end of the motor is connected to a transmission structure, the output end of the motor is connected to a conveying structure, the drying box is provided with a material receiving trough, and a baffle is slidably connected to the inner wall of the material receiving trough. The transmission structure includes a conveyor shaft. The drying chamber has a first rotating groove, a second rotating groove, and a third rotating groove. The conveyor shaft is connected to the output end of a motor. The conveyor shaft is connected to a first driving wheel and a second driving wheel. A third transmission shaft is rotatably connected to the inner wall of the first rotating groove. The third transmission shaft is connected to a first driven wheel. The first driven wheel and the first driving wheel are connected to a first conveyor belt. A first transmission shaft is rotatably connected to the inner wall of the second rotating groove. The first transmission shaft is connected to a second driven wheel. The second driven wheel and the second driving wheel are connected to a second conveyor belt. The third transmission shaft and the first transmission shaft are respectively connected to several first bevel gears. The inner walls of the five third rotating grooves are respectively rotatably connected to second transmission shafts. The second transmission shafts are connected to second bevel gears, which mesh with the first bevel gears. The second transmission shafts are connected to a rotating wheel. The rotating wheel is connected to several rubber levers. The inner wall of the drying chamber has several swing holes. A rotating shaft is rotatably connected to the side wall of each swing hole. The rotating shaft is connected to a pressure plate and a swing plate. The third rotating groove and the swing holes are connected in communication.

[0006] Preferably, the conveying structure includes a conveying box, a conveying pipe and a return pipe. The upper and lower ends of the conveying box and the drying box are connected by the conveying pipe and the return pipe, respectively. The conveying shaft is connected to an auger, and the side wall of the auger abuts against the inner wall of the conveying box.

[0007] Preferably, both the conveying pipe and the return pipe are inclined, with the conveying pipe inclined downward on the side near the drying box and the return pipe inclined downward on the side near the conveying box.

[0008] Preferably, the swing plate is connected to a rubber gasket.

[0009] Preferably, the bottom of the drying chamber is inclined.

[0010] Preferably, the drying chamber has an air outlet pipe connected to its side wall, and a second filter screen is connected to the inner wall of the air outlet pipe.

[0011] Preferably, the drying chamber is connected to a first filter screen.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows: (1) The transmission structure described herein uses a motor to drive the conveyor shaft to rotate, which in turn drives the first and second drive wheels to rotate via the first and second conveyor belts, respectively, and the third and first drive shafts to rotate. This is achieved through the meshing of the first and second bevel gears, causing the rubber lever on the wheel to rotate synchronously with the second drive shaft. When the rubber lever rotates, it periodically actuates the swing plate, causing the shaft and pressure plate to swing back and forth within the swing hole, thus transporting and actuating the bio-fertilizer clumps in the drying chamber. This design effectively breaks up the bio-fertilizer clumps that adhere together in a moist state, resulting in more uniform material dispersion, increased contact area with the drying components, and significantly improved moisture evaporation efficiency. It solves the problem of low and uneven drying efficiency caused by the difficulty in dispersing clumps in existing equipment, while also preventing excessively high local temperatures inside the clumps due to long-term retention, thus protecting the activity of the probiotics.

[0013] (2) In the conveying structure described above, the auger connected to the conveying shaft can re-transport the material at the bottom of the drying chamber to the top of the drying chamber through the conveying pipe and the return pipe when it rotates, forming a circular conveying path for the material. This design allows the bio-fertilizer to be dried multiple times between the drying chamber and the conveying chamber, avoiding the problem of incomplete drying in a single cycle. Combined with the stirring and pushing effect of the auger on the material, it further enhances the dispersion effect of the material, ensuring that each part of the material can fully contact the low-temperature drying environment, effectively improving the overall drying quality and efficiency.

[0014] (3) The inclined design of the conveying pipe and return pipe utilizes gravity to allow the material to flow smoothly without additional power during the conveying process. The conveying pipe is inclined downwards on the side near the drying box, which facilitates the efficient introduction of material from the conveying box into the drying box; the return pipe is inclined downwards on the side near the conveying box, which facilitates the smooth return of material from the drying box to the conveying box. This design reduces the risk of material retention and blockage in the pipes, ensures the stability and continuity of the material circulation system, makes the equipment operation more reliable, and reduces maintenance costs.

[0015] (4) The rubber pads connected to the swing plate increase the friction when the swing plate comes into contact with the bacterial fertilizer clumps through the buffering effect of the elastic material. This more effectively breaks up the clumps while reducing the rigid collision between the swing plate and the inner wall of the drying box, thus reducing the noise and mechanical wear of the equipment.

[0016] (5) The inclined setting of the bottom of the drying chamber allows the dried material to automatically gather towards the feeding trough under the action of gravity, avoiding the accumulation and residue of material in the corner of the bottom of the chamber.

[0017] (6) The second filter screen on the inner wall of the air outlet duct can effectively filter the dust and fine particles generated during the drying process, preventing them from being discharged with the airflow and polluting the environment, while also avoiding material waste. Through the air circulation design of the air outlet duct, it is ensured that the moisture and accumulated heat in the drying chamber can be discharged in time, maintaining a dry environment inside the chamber. Combined with the low-temperature drying effect of the drying components, a stable heat and moisture exchange cycle is formed, providing suitable drying conditions for the bio-fertilizer and ensuring that the activity of probiotics is not damaged.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figures 1 to 5 The illustrated low-temperature drying equipment for bio-fertilizer includes a drying chamber 1, such as... Figure 1 and Figure 2 As shown, a feed pipe 5 is connected to the right side wall of the drying box 1, a drying component 4 is connected to the top of the drying box 1, an equipment box 7 is connected to the bottom of the drying box 1, a motor 3 is connected to the left side of the inner wall of the equipment box 7, a transmission structure 29 is connected to the output end of the motor 3, a conveying structure is connected to the output end of the motor 3, a material picking trough 17 is opened on the right side wall of the drying box 1, and a baffle 34 is slidably connected to the inner wall of the material picking trough 17.

[0020] The transmission structure 29 includes a conveying shaft 33, and the drying box 1 has a first rotating groove, a second rotating groove, and a third rotating groove 18, as shown below. Figure 2 and Figure 3 As shown, the bottom of the conveyor shaft 33 is connected to the output end of the motor 3, and the bottom of the conveyor shaft 33 is connected to the first drive wheel 8 and the second drive wheel 9. The inner wall of the first rotating groove is rotatably connected to the third transmission shaft 35, as shown. Figure 3 As shown, the bottom of the third drive shaft 35 is connected to a first driven wheel 27. The first driven wheel 27 and the first driving wheel 8 are connected to a first conveyor belt 10. The inner wall of the second rotating groove is rotatably connected to a first drive shaft 26. The bottom of the first drive shaft 26 is connected to a second driven wheel 28. The second driven wheel 28 and the second driving wheel 9 are connected to a second conveyor belt 11. Several first bevel gears 30 are connected to the upper ends of the third drive shaft 35 and the first drive shaft 26, respectively. There are a total of five third rotating grooves 18, three on the left and two on the right. The inner wall of the third rotating groove 18 is rotatably connected to a second drive shaft 20. The second drive shaft 20 is connected to a second bevel gear 31, which meshes with the first bevel gear 30. The second drive shaft 20 is connected to two rotating wheels 21, and the rotating wheels 21 are connected to several rubber levers 22, such as... Figure 2 and Figure 4 As shown, the inner wall of the drying oven 1 has several swing holes 19. The side wall of the swing hole 19 is rotatably connected to a rotating shaft 23. The left side of the rotating shaft 23 is connected to a pressure plate 24, and the right side of the rotating shaft 23 is connected to a swing plate 16. The third rotating groove 18 is connected to the swing hole 19.

[0021] like Figure 2 As shown, the conveying mechanism includes a conveying box 2. The upper and lower ends of the conveying box 2 and the drying box 1 are connected by a conveying pipe 12 and a return pipe 13, respectively. The conveying shaft 33 is connected to an auger 25, which abuts against the inner wall of the conveying box 2.

[0022] like Figure 2 As shown, both the conveying pipe 12 and the return pipe 13 are inclined. The conveying pipe 12 is inclined downward on the side closer to the drying box 1, and the return pipe 13 is inclined downward on the side closer to the conveying box 2.

[0023] like Figure 2 and Figure 4 As shown, a rubber pad 32 is connected to the bottom left side of the swing plate 16.

[0024] like Figure 2 As shown, the bottom of the inner cavity of the drying oven 1 is inclined.

[0025] like Figure 1 and Figure 3 As shown, an air outlet pipe 6 is connected to the right side wall of the drying oven 1, and a second filter screen 15 is connected to the inner wall of the air outlet pipe 6.

[0026] like Figure 2As shown, the top of the drying chamber 1 is connected to the first filter screen 14 directly below the drying assembly 4.

[0027] When the equipment is working, the moist bio-fertilizer enters the drying chamber 1 through the feed pipe 5. The drying assembly 4 is activated to provide a low-temperature drying environment, and at the same time, the motor 3 drives the conveyor shaft 33 to rotate. The conveyor shaft 33 drives the first drive wheel 8 and the second drive wheel 9 to rotate synchronously. The first drive wheel 8 drives the first driven wheel 27 through the first conveyor belt 10, which in turn drives the third transmission shaft 35 to rotate. The second drive wheel 9 drives the second driven wheel 28 through the second conveyor belt 11, which in turn drives the first transmission shaft 26 to rotate. The first bevel gear 30 on the third transmission shaft 35 and the first transmission shaft 26 meshes with the second bevel gear 31 on the second transmission shaft 20, causing the second transmission shaft 20 to drive the rotating wheel 21 and the rubber lever 22 to rotate. During the rotation of the rubber lever 22, it periodically actuates the swing plate 16, causing the rotating shaft 23 to drive the pressure plate 24 to swing back and forth in the swing hole 19, which beats the bio-fertilizer clumps in the drying chamber 1, breaking and dispersing the clumps, and at the same time assisting the material to slide to the bottom of the drying chamber 1.

[0028] Meanwhile, the conveyor shaft 33 drives the auger 25 to rotate, transporting the material from the return pipe 13 into the bottom of the conveyor box 2 upwards via the auger 25 until it reaches the top of the drying box 1 via the inclined conveyor pipe 12. The material is then tapped again by the swing plate 16 and falls back to the bottom of the drying box 1, sliding along the inclined bottom. The material then flows back into the conveyor box 2 via the return pipe 13 for further drying. The inclined design of the conveyor pipe 12 and the return pipe 13 ensures smooth material flow under gravity, requiring no additional power.

[0029] Most of the hot air is discharged outward through the air outlet duct 6, ensuring that heat does not accumulate in the drying chamber 1 and preventing the colonies from losing their activity due to high temperature. At the same time, the conveyor box 2 further cools down the bacterial fertilizer during the circulating feeding process, preventing heat accumulation.

[0030] The moisture and heat generated during the drying process are discharged through the air outlet 6. The second filter 15 filters dust, and the first filter 14 blocks impurities during the feeding stage, ensuring the drying effect and equipment reliability. After drying is completed, the sliding baffle 34 opens the material inlet 17 to collect the dried bio-fertilizer.

[0031] The specific implementation process is as follows: When using the equipment, close the baffle 34 of the feeding trough 17, set the low-temperature drying temperature on the drying component 4, pour the moistened microbial fertilizer into the feed pipe 5, then turn on the power to the motor 3, driving the conveyor shaft 33 to rotate. This drives the first drive wheel 8 and the second drive wheel 9 to rotate the third drive shaft 35 and the first drive shaft 26 via the conveyor belt. Through the meshing of the bevel gear, the second drive shaft 20 drives the rotating wheel 21 and the rubber lever 22 to rotate, periodically actuating the swing plate 16 to make the pressure plate 24 beat the microbial fertilizer clumps to break them up and disperse them, and then convey the microbial fertilizer to the bottom of the drying box 1. At the same time, the conveyor shaft 33 drives the auger 25 to enter the bottom of the conveyor box 2 from the return pipe 13. The material is conveyed upward through the auger 25 until it is sent to the top of the drying box 1 through the inclined conveyor pipe 12. After being patted by the swing plate 16, the material falls to the bottom of the drying box 1 and slides along the bottom of the inclined box. The material is then returned to the conveyor box 2 through the return pipe 13 for recycling and drying. The low-temperature airflow generated by the drying component 4 passes through the material layer, and the moisture and accumulated hot air are filtered and discharged through the second filter screen 15 of the air outlet pipe 6. When the drying is completed by the humidity sensor or the timer device (2-3 hours), the drying component 4 is turned off, the baffle 34 is slid open, and the dried microbial fertilizer slides down from the bottom of the inclined box for collection under the action of gravity. After collection, the motor 3 resets the baffle 34.

[0032] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
