Description

Technical Field

[0001] This utility model relates to the technical field of grain air drying, and in particular to a grain storage and drying silo that provides uniform and efficient grain drying. Background Technology

[0002] With the increasing demand for large-scale grain storage, air-drying silos, as key equipment for realizing the integration of grain drying and storage, have a crucial impact on the preservation quality and economic benefits of grain due to their operational efficiency and drying uniformity.

[0003] During the use of a drying silo, the grain near the outer layer dries faster than the grain inside. To ensure more even drying, the grain needs to be turned over after a certain drying time. Specifically, turning over involves releasing the grain from the discharge port and then returning it to the silo through the inlet. During this process, the released grain moves as it is returned, effectively turning the grain over. The turned-over grain then undergoes further drying within the silo, resulting in a more even drying process.

[0004] To improve the efficiency of grain transfer, a conveyor system is used to simultaneously transfer the released grain from the inlet into the silo during the unloading process. However, the lower part of the drying silo is usually designed as an inverted trapezoidal structure, with the outlet located at the bottom of the trapezoid. This structure results in inconsistent grain loading speeds at different longitudinal positions; specifically, the loading speed is faster in the longitudinal area near the outlet, while the speed is relatively slower on the sides. This can cause grain that has been re-entered into the silo to flow out again from the middle area, while grain on the sides remains inside the silo, thus failing to achieve the goal of full-space, integrated grain transfer and affecting the overall drying effect.

[0005] Furthermore, traditional air-drying silos widely employ a triangular baffle mesh structure inside. This design results in variations in the thickness of the grain storage areas formed between the baffle mesh cylinders, leading to uneven drying of the stored grain. Utility Model Content

[0006] To address the problem of uneven grain drying in traditional drying silos, the purpose of this invention is to provide a grain drying silo that provides uniform and efficient grain storage.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A uniform and efficient grain drying silo includes a frame 1, a baffle net, and rhomboid cylinders 3. The baffle net is installed on the frame 1, and the baffle net encloses the grain storage silo 2. The grain storage silo 2 is provided with a grain inlet area 21, a grain storage area 22, and a guide area 23 connected sequentially from top to bottom. The grain inlet area 21 has a grain inlet 24 at its top. The horizontal cross-sectional dimension of the guide area 23 gradually decreases from top to bottom, and the guide area 23 has a grain outlet 25 at its bottom. Multiple rhomboid cylinders 3 are evenly distributed inside the grain storage silo 2. Both ends of the rhomboid cylinders 3 are connected to the frame 1, and both ends of the rhomboid cylinders 3 abut against the baffle net. The multiple rhomboid cylinders 3 divide the interior of the grain storage silo 2 into a mesh-like grain storage space 4. The rhomboid cylinders 3 are thin-walled cylindrical structures, and are provided with air ducts 5 that run through the front and back. Multiple ventilation holes 6 are distributed on the side walls of the rhomboid cylinders 3, and the air ducts 5 are connected to the multiple ventilation holes 6.

[0009] Furthermore, the multiple rhomboid cylinders 3 have the same specifications, dimensions, and inclination angle; each row of rhomboid cylinders 3 is arranged at equal intervals along the horizontal direction, any two adjacent rows of rhomboid cylinders 3 are staggered, and the distance between two adjacent rhomboid cylinders 3 along any diagonal direction is equal.

[0010] Furthermore, the frame 1 includes a beam frame 11 and a steel reinforcement cage 12. The steel reinforcement cage 12 is arranged on the beam frame 11 and is located inside the retaining mesh. Both ends of the rhomboid cylinder 3 are connected to the steel reinforcement cage 12.

[0011] Furthermore, the rhomboid cylinder 3 includes a support 31, a rhomboid frame 32, and a ventilation net 33. A rhomboid frame 32 is welded to each of the front and rear ends of the support 31. The ventilation net 33 surrounds the outer periphery of the support 31 and forms the side wall of the rhomboid cylinder 3. The ventilation net 33 is provided with a plurality of ventilation holes 6. Each rhomboid frame 32 is welded to the reinforcing steel frame 12. Each rhomboid frame 32 is riveted to the retaining mesh.

[0012] Furthermore, the rhomboid cylinder 3 is a square cylinder; one side wall of the rhomboid cylinder 3 forms a 45° angle with the horizontal plane.

[0013] Furthermore, the high-efficiency air-drying silo also includes multiple material-blocking devices 7. The grain storage area 22 has multiple diamond-shaped cylinders 3 in any row along the horizontal direction, and a material-blocking device 7 is installed between any two adjacent diamond-shaped cylinders 3. When grain is discharged from the grain outlet 25, the flow rate between the two diamond-shaped cylinders 3 is adjusted by the material-blocking device 7.

[0014] Furthermore, the high-efficiency air-drying chamber also includes a discharge hopper 8, and the grain outlet 25 is connected to a discharge hopper 8; the discharge hopper 8 is provided with an outlet 81.

[0015] Furthermore, the high-efficiency air-drying chamber also includes a foundation 9, and the bottom end of the beam frame 11 is connected to the foundation 9.

[0016] Furthermore, the high-efficiency air-drying silo also includes an elevator 10, which is located on one side of the grain storage silo 2.

The feed hopper 101 is connected to the lower end of the elevator pipe 102. A conveying device is installed inside the elevator pipe 102. The upper end of the elevator pipe 102 is connected to one end of the conveying pipe 104, and the other end of the conveying pipe 104 is connected to the grain inlet 24. The motor 103 is used to drive the conveying device.

[0017] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies:

Each row of rhomboid cylinders is arranged at equal intervals along the horizontal direction, and any two adjacent rows of rhomboid cylinders are staggered. The distance between any two adjacent rhomboid cylinders along any diagonal direction is equal. This distribution divides the interior of the grain storage silo into grain storage spaces of uniform thickness, thereby making the ventilation effect of the grain more uniform.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Please refer to Figures 1 to 6 The diagram shows a uniform and efficient grain drying silo, comprising a frame 1, a baffle net, and a diamond-shaped cylinder 3. The baffle net is installed on the frame 1, forming a grain storage silo 2. The baffle net serves to contain the grain and provide ventilation. The baffle net is preferably made of galvanized mesh, which is steel mesh that has been galvanized to form a zinc layer on its surface, providing high strength and corrosion resistance (the baffle net structure is not shown in the attached diagram to simplify the view and clearly show the internal structure of the grain storage silo 2). The grain storage silo 2 is equipped with a trapezoidal grain inlet area 21, a cylindrical grain storage area 22, and an inverted trapezoidal guide area 23, which are connected sequentially from top to bottom. The top of the grain inlet area 21... The grain storage silo 2 is equipped with a grain inlet 24 and a grain outlet 25 at the bottom of the flow guide zone 23. The horizontal cross-sectional dimension of the flow guide zone 23 gradually decreases from top to bottom. Multiple rhomboid cylinders 3 are evenly distributed inside the grain storage silo 2. Both ends of the rhomboid cylinders 3 are connected to the frame 1 and both ends of the rhomboid cylinders 3 abut against the baffle net. Multiple rhomboid cylinders 3 divide the inside of the grain storage silo 2 into a mesh grain storage space 4. The rhomboid cylinders 3 are thin-walled cylindrical structures with air ducts 5 running through them. Multiple ventilation holes 6 are distributed on the side walls of the rhomboid cylinders 3. The air ducts 5 are connected to the multiple ventilation holes 6. Air enters the grain storage space 4 through the ventilation holes 6, thereby drying the grain in the grain storage space 4.

[0029] Furthermore, in a preferred embodiment, the multiple rhomboid cylinders 3 have the same dimensions and inclination angle; each row of rhomboid cylinders 3 is arranged at equal intervals along the horizontal direction, and any two adjacent rows of rhomboid cylinders 3 are staggered, with the distance between any two adjacent rhomboid cylinders 3 along any diagonal direction being equal. This distribution divides the interior of the grain storage silo 2 into grain storage spaces 4 of uniform thickness, thereby making the ventilation effect of the grain more uniform.

[0030] Furthermore, in a preferred embodiment, the distance between two adjacent rhomboid cylinders 3 along any oblique direction ranges from 8cm to 18cm.

[0031] Furthermore, in a preferred embodiment, the frame 1 includes a beam frame 11 and a steel reinforcement cage 12. The steel reinforcement cage 12 is arranged on the beam frame 11 and is located inside the retaining mesh. Both ends of the rhomboid cylinder 3 are connected to the steel reinforcement cage 12, and the function of the steel reinforcement cage 12 is to fix the rhomboid cylinder 3.

[0032] Furthermore, in a preferred embodiment, the beam frame 11 includes a plurality of vertical beams 111 and a plurality of horizontal beams 112, with at least two horizontal beams 112 connecting adjacent vertical beams 111.

[0033] Furthermore, in a preferred embodiment, the steel reinforcement frame 12 includes a plurality of vertical steel bars 121 and a plurality of horizontal steel bars 122. The plurality of vertical steel bars 121 on each side of the grain storage silo 2 are arranged at equal intervals. The plurality of vertical steel bars 121 on each side are welded with a plurality of horizontal steel bars 122, and the function of the horizontal steel bars 122 is to reinforce the vertical steel bars 121. The end of each vertical steel bar 121 is welded to the crossbeam 112.

[0034] Furthermore, in a preferred embodiment, the rhomboid cylinder 3 includes a support 31, a rhomboid frame 32, and a ventilation net 33. A rhomboid frame 32 is welded to each of the front and rear ends of the support 31. The ventilation net 33 surrounds the outer periphery of the support 31 and forms the sidewall of the rhomboid cylinder 3. The ventilation net 33 is used to ensure that grain does not leak from the grain storage space 4 into the air duct 5. The ventilation net 33 is provided with multiple ventilation holes 6 (in order to simplify the view and clearly show the internal structure of the rhomboid cylinder 3, only part of the structure of the ventilation net 33 is shown in the figure). Air enters into the grain storage space 4 through the ventilation holes 6, thereby drying the grain in the grain storage space 4. Each rhomboid frame 32 is welded to the steel frame 12. Each rhomboid frame 32 is riveted to the baffle net, which can play a role in fixing each other and can also prevent grain from leaking out from between the rhomboid frame 32 and the baffle net.

[0035] Furthermore, in a preferred embodiment, each rhomboid frame 32 is formed by welding four angle steels sequentially; each rhomboid frame 32 is welded to at least one vertical steel bar 121. Traditional drying silos have multiple layers of horizontally arranged support beams inside the silo, with multiple triangular baffles connected to each support beam. This invention places the structure used to fix the rhomboid cylinders 3 around the grain storage silo 2, saving more internal space compared to traditional drying silos.

[0036] Furthermore, in a preferred embodiment, the ventilation mesh 33 is preferably made of galvanized mesh, which is made of steel mesh that has been galvanized to form a zinc layer on its surface, giving it high strength and corrosion resistance.

[0037] Furthermore, in a preferred embodiment, the rhomboid cylinder 3 is a square cylinder; one side wall of the rhomboid cylinder 3 forms a 45° angle with the horizontal plane. This invention uses a square cylinder to achieve uniform grain layering, with a layer thickness ranging from 8cm to 18cm. The ends of the square cylinder employ a combination of welding and riveting, resulting in a simple and durable structure, reduced manufacturing costs, and lower initial investment for users. The drying effect of this invention is superior to most existing products. Because the rhomboid cylinder 3 has a square structure, the contacted grain forms uniformly divided chambers, resulting in superior ventilation and drying speed. Without relying on other energy sources, efficiency is increased by at least 20%.

[0038] Furthermore, in a preferred embodiment, the high-efficiency drying silo also includes multiple baffle devices 7. Multiple rhomboid cylinders 3 are arranged in any horizontal row in the grain storage area 22, with a baffle device 7 installed between any two adjacent rhomboid cylinders 3. When grain is discharged from the outlet 25, the flow rate between the two rhomboid cylinders 3 is adjusted by the baffle device 7. Furthermore, by adjusting the baffle devices 7 at different positions, the flow rate of grain can be controlled in zones to ensure uniform distribution of stored grain. The baffle device 7 can freely control the position and sequence of grain transfer, improving the uniformity of drying, as well as the position and time of the upper and lower grain layers, making operation simple and efficient. Example 1: Because the grain stored in the grain storage space 4 has a certain thickness, the drying speed of the outer layer of grain is faster than that of the inner layer, meaning the grain near the baffle mesh or ventilation mesh 33 dries faster. To ensure more uniform drying of the grain in the grain storage space 4, it is necessary to transfer the grain after a certain drying time. The process of grain repacking involves releasing grain from the discharge port and then re-infeeding it through the inlet. The re-infeeding process causes the grain to flow, altering its original inner and outer layer structure, thus achieving a tumbling effect. The tumbled grain then undergoes air drying, resulting in more uniform drying. During the grain release process, the flow rate can be controlled by adjusting the baffles 7 at different positions, preventing high flow rates in the middle and avoiding overflow of the re-infeeding grain, thereby effectively controlling the uniformity of grain drying. Example 2: Two batches of grain are stored in storage bin 2 at different times. When the first batch of grain has reached the drying time and needs to be released, the flow rate can be controlled by adjusting the baffles 7 at different positions, preventing high flow rates in the middle and avoiding overflow of the second batch of grain located at the top, thus effectively controlling the release of the first batch of grain.

[0039] Furthermore, in a preferred embodiment, multiple material blocking devices 7 are provided between the multiple diamond-shaped cylinders 3 at the bottom of the grain storage area 22. The multiple material blocking devices 7 are located at the bottom of the grain storage silo 2, which makes it easier for personnel to operate.

[0040] Furthermore, in a preferred embodiment, the material blocking device 7 is slidably installed between the two rhomboid cylinders 3.

[0041] Furthermore, in a preferred embodiment, the material blocking device 7 includes a fixed plate 71 and a movable plate 72. The left and right ends of the fixed plate 71 are welded to the diamond-shaped tubes 3 on both sides, respectively. The movable plate 72 is slidably connected to the fixed plate 71. A groove is provided on each side of the bottom of the fixed plate 71, and the left and right ends of the movable plate 72 are respectively installed in a groove. The fixed plate 71 has multiple spaced openings 711. The movable plate 72 includes two connecting rods 721, multiple baffles 722, and a handle 723. The two connecting rods 721 are symmetrically arranged on the left and right sides, and multiple spaced baffles 722 are connected between the two connecting rods 721. Each baffle 722 corresponds to one opening 711. When the movable plate 72 is pushed or pulled, one baffle 722 can adjust the size of one opening 711. When the baffle 722 completely covers the opening 711, the opening 711 is closed. The handle 723 is connected to the end of the connecting rod 721, and the handle 723 is located on the outside of the material blocking mesh.

[0042] Furthermore, in a preferred embodiment, the high-efficiency air-drying chamber also includes a discharge hopper 8, and the grain outlet 25 is connected to a discharge hopper 8; the discharge hopper 8 is provided with an outlet 81, which can be opened when grain needs to be discharged.

[0043] Furthermore, in a preferred embodiment, the high-efficiency air-drying chamber also includes a foundation 9, and the bottom end of the beam frame 11 is connected to the foundation 9; furthermore, the bottom end of each vertical beam 111 is connected to a foundation 9; the foundation 9 is a reinforced concrete foundation, and the foundation 9 is connected to the ground, which plays a role in stabilizing the entire structure.

[0044] Furthermore, in a preferred embodiment, the high-efficiency air-drying silo also includes an elevator 10, which is disposed on one side of the grain storage silo 2. The elevator 10 is preferably a bucket elevator. The elevator 10 includes a feed hopper 101, an elevator pipe 102, a motor 103, a conveying pipe 104, and a conveying device. The bottom of the elevator pipe 102 is fixed to the ground. The feed hopper 101 is connected to the lower end of the elevator pipe 102. A conveying device is installed inside the elevator pipe 102. The upper end of the elevator pipe 102 is connected to one end of the conveying pipe 104, and the other end of the conveying pipe 104 is connected to the grain inlet 24. The motor 103 is used to drive the conveying device to work. Multiple hoppers are arranged on the conveying device. The motor 103 drives the conveying device to rotate, and the hoppers convey the grain entering from the feed hopper 101 to the top of the elevator pipe 102, and then transport the grain into the grain storage silo 2 through the conveying pipe 104.

[0045] Furthermore, in a preferred embodiment, please refer to Figure 1As shown, the grain storage silo 2 is provided with a grain inlet area 21, a grain storage area 22 and multiple guide areas 23 connected from top to bottom. The number of guide areas 23 can be set according to the actual length of the grain storage silo 2; preferably, when the length of the grain storage silo 2 is 6 meters, two guide areas 23 are provided.

[0046] Furthermore, in a preferred embodiment, please refer to Figure 1 As shown, this utility model has two grain storage bins 2, and the elevator 10 is located between the two grain storage bins 2; the elevator 10 has two conveying pipes 104, and one conveying pipe 104 corresponds to one grain storage bin 2.

[0047] Working principle:

[0048] When feeding grain into the grain storage silo 2, the elevator 10 is first turned on, and grain is fed in through the feed hopper 101. At this time, the motor 103 drives the conveyor to rotate, and multiple hoppers continuously convey the grain fed from the feed hopper 101 to the top of the lifting pipe 102. Then, the grain passes through the conveying pipe 104 and is transported from the grain inlet 24 into the grain storage space 4. Because the side wall of the rhomboid cylinder 3 is inclined to the horizontal plane, the grain flows down the inclined surface and gradually accumulates. After feeding is completed, the high-efficiency air-drying silo can achieve the air-drying function under normal conditions. Specifically, external air passes through the baffle net and enters the air duct 5, and enters the grain storage space 4 through the ventilation hole 6, thereby air-drying the grain accumulated in the grain storage space 4. Because the rhomboid cylinder 3 divides the interior of the grain storage silo 2 into grain storage spaces 4 of uniform thickness, the ventilation effect of the grain is more uniform. When it is necessary to unload the grain, the outlet 81 is opened, and the grain passes through the discharge hopper 8 and flows out from the outlet 81. When it is not necessary to release all the grain in the grain storage silo 2, the flow of grain can be controlled by adjusting the baffle devices 7 at different positions to ensure that the remaining grain is evenly distributed.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
