Description
Technical Field
[0001] This utility model belongs to the field of grain storage technology, specifically relating to a drying silo. Background Technology
[0002] Ventilated and dry grain storage silos, also known as natural drying silos or natural air-drying silos, are collectively referred to as drying silos. Currently, existing silos consist of three parts: a steel mesh enclosure, a metal frame, and a galvanized iron top cover. The silo body is formed by a galvanized steel mesh frame with steel strips, and the seams are secured with positioning pins and a set of locks. The silo's structural features include easy assembly, disassembly, and relocation; it can be used for both ear and grain storage; it is inexpensive and economical; and it can be used flexibly according to different seasonal climate conditions and capacity requirements. In terms of application effectiveness, it can fully utilize natural wind and light sources to reduce moisture content during grain storage, and has functions such as rodent prevention, mold prevention, spillage prevention, energy saving, and environmental protection.
[0003] For the air drying of temporary grain reserves, current common hot air drying silos have drawbacks such as long processing time, low drying uniformity, and difficulty in guaranteeing quality. In actual drying processes, grain near the end of the air duct dries too quickly, while grain near the end and top of the duct dries more slowly, resulting in uneven drying. Therefore, a drying silo capable of collecting and uniformly drying temporary grain reserves is needed. Summary of the Invention
[0004] This invention addresses the problem of uneven and ineffective drying of stored grain in a drying chamber by providing a drying chamber that solves the aforementioned issues.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A drying chamber includes a chamber body and an air hood disposed inside the chamber body. Both the chamber body and the air hood have through holes. A hot air blower is disposed outside the drying chamber to supply hot air to the chamber body and the air hood. The hot air flows from inside the air hood to outside the air hood, thereby solving the problem of dampness in the middle part of the grain stored inside the chamber body.
[0007] The air hoods include a main air hood and secondary air hoods protruding from both sides of the main air hood, with the secondary air hoods evenly distributed on both sides of the main air hood. The main air hoods and the secondary air hoods are connected. The even distribution of the secondary air hoods separates the stored grain, reduces grain accumulation, and allows the stored grain at the intervals between each secondary air hood to be effectively dried.
[0008] In a further embodiment, the top of the silo is open, the bottom of the main hood is open, and the bottom of the main hood is in contact with the silo.
[0009] In a further embodiment, the silo body has a rectangular cross-section, with chamfered corners at all four edges. The chamfered corners reduce the possibility of some stored grain failing to dry due to dead angles.
[0010] In a further embodiment, the secondary hood is symmetrically arranged around the centerline of the main hood, with the ends of the secondary hood tilted away from the hot air blower.
[0011] In a further embodiment, an air supply duct is installed in the silo and the main air hood, and one end of the air supply duct is connected to a hot air blower.
[0012] In a further embodiment, the hot air blower is provided with a baffle plate at the air outlet end to adjust the hot air flow, and the baffle plate is located inside the main air hood.
[0013] In a further embodiment, a rod is inserted through the end of the chamber away from the hot air blower, and the end of the rod extending into the main air hood is fixedly connected to a baffle plate. The rod is used to push the baffle plate to move, guiding the airflow at different positions as the position of the baffle plate changes.
[0014] In a further embodiment, a hollow cylinder is fitted onto the rod, and the rod reciprocates within the hollow cylinder. The hollow cylinder is fixedly positioned between the silo and the main air hood. The hollow cylinder facilitates the movement of the rod.
[0015] In a further embodiment, the hollow cylinder has protrusions at both ends, located on the outer wall of the hopper and the inner wall of the main air hood, respectively. A limiting ring is fitted onto each protrusion to secure the hollow cylinder.
[0016] The beneficial effects of this utility model through the above technical solution are as follows:
[0017] 1. This utility model is mainly used for the temporary drying and storage of harvested grain. This utility model uses a hot air blower to supply air into the air hood, allowing hot air to diffuse from inside the hood to the outside. The hot air passes through the through-holes on the surface of the air hood to dry the grain stored between the storage bin and the air hood, and diffuses through the through-holes on the surface of the storage bin. The evenly distributed secondary air hoods reduce grain accumulation, ensuring effective drying between each secondary air hood, thereby achieving the desired drying effect and preventing mold growth.
[0018] 2. The four corners of the silo are beveled to reduce the possibility of the stored grain not being able to dry due to dead corners.
[0019] 3. When the push rod moves the baffle plate towards the air outlet of the hot air blower, the closer the baffle plate is to the air outlet, the stronger and more concentrated the drying effect on both sides. As the position of the baffle plate moves continuously, it changes the diffusion range and intensity of the hot air, so as to dry the stored grain in different positions evenly.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0028] Example 1
[0029] like Figures 1-5 As shown, this embodiment provides a drying chamber, including a chamber body 1 and a fan hood disposed inside the chamber body 1. Both the chamber body 1 and the fan hood are provided with through holes. A hot air blower 9 is provided outside the drying chamber to provide hot air to the chamber body 1 and the fan hood.
[0030] The air hood includes a main air hood 2 and secondary air hoods 3 protruding from both sides of the main air hood 2, with the secondary air hoods 3 evenly distributed on both sides of the main air hood 2. The main air hood 2 and the secondary air hoods 3 are connected. Hot air flows from inside the air hood to the outside, thereby solving the problem of dampness in the central part of the storage grain inside the silo 1. Specifically, the hot air generated by the hot air blower 9 flows into the main air hood 2 and out through the through holes on the main air hood 2 and the secondary air hoods 3, drying the storage grain outside the main air hood 2 and the secondary air hoods 3. Then, the hot air passes through the storage grain and diffuses outward through the through holes on the silo 1, thus completing the drying process of the storage grain. To prevent the storage grain inside the silo 1 from leaking out of the silo 1 or entering the air hood, in this embodiment, the through holes on the silo 1 and the air hoods are smaller than the particle size of the storage grain to be collected, just enough to allow the hot air to pass through.
[0031] Furthermore, the storage unit 1 and the hood are not limited to structures composed of plates, but also adopt structures composed of steel mesh and other material combinations with ventilation effects, so that they can collect the stored grain while retaining the function of ventilation.
[0032] The top of the silo 1 is open, and the bottom of the main air hood 2 is open, with the bottom of the main air hood 2 in contact with the silo 1. The top opening of the silo 1 facilitates the filling of the stored grain, which falls into the silo 1 and onto the outer surface of the main air hood 2, thereby completing the collection of the stored grain.
[0033] The cross-section of the silo body 1 is rectangular, and all four corners are chamfered. The chamfering of the four corners of the silo body 1 is to reduce dead corners, because dead corners will prevent some of the stored grain from being dried evenly, while the chamfering facilitates the even drying of the stored grain by hot air.
[0034] The secondary air hoods 3 are symmetrically arranged around the center line of the main air hood 2, with the ends of the secondary air hoods 3 inclined away from the hot air blower 9. Specifically, the inclination of the ends of the secondary air hoods 3 away from the hot air blower 9 facilitates the flow of hot air, thereby ensuring uniform drying of the stored grain between the secondary air hoods 3.
[0035] An air supply duct 8 is installed in the silo body 1 and the main air hood 2, and one end of the air supply duct 8 is connected to a hot air blower 9. The air supply duct 8 guides hot air into the main air hood 2, and diffuses it from inside the main air hood 2 to the outside of the main air hood 2, and diffuses it into the grain stored between the main air hood 2 and the silo body 1, thereby drying the stored grain.
[0036] The hot air blower 9 is provided with a baffle plate 5 at the air outlet end to adjust the hot air flow, and the baffle plate 5 is located inside the main air cover 2;
[0037] A rod 4 is inserted through one end of the storage compartment 1 away from the hot air blower 9. The end of the rod 4 extending into the main air hood 2 is fixedly connected to a baffle plate 5. Specifically, the shape and size of the baffle plate 5 are consistent with the shape and size of the internal cross-section of the main air hood 2. When the rod 4 is pushed, the baffle plate 5 is moved towards the air outlet of the hot air blower 9. The closer the baffle plate 5 is to the air outlet, the stronger and more concentrated the drying effect on both sides. As the position of the baffle plate 5 continuously moves, the diffusion range and intensity of the hot air are changed, allowing for uniform drying of the stored grain in different locations. When using this drying chamber, the operator first places the stored grain into the space between the chamber body 1 and the air hood, and then starts the hot air blower 9. The hot air enters the main air hood 2 and the secondary air hood 3 through the air supply pipe 8, and enters the chamber body 1 through the through holes on the main air hood 2 and the secondary air hood 3. The hot air circulates between the stored grains, thereby satisfying the drying of the stored grains. Then the hot air passes through the stored grains and diffuses outward from the through holes on the chamber body 1 and the opening at the top, thus realizing the process of drying the stored grains with hot air.
[0038] The space between each secondary air hood 3 can accommodate some stored grain, which further separates the stored grain in the silo 1. This improves the problem that hot air cannot pass through due to excessively thick stacked stored grain, resulting in some stored grain not being dried. The chamfered corners of the silo 1 facilitate the diffusion of hot air, ensuring uniform drying of the stored grain and reducing the situation where poor hot air diffusion due to dead corners prevents some stored grain from being dried.
[0039] As needed, staff can also hold the handle at one end of the rod 4 and push the rod 4. The rod 4 drives the wind deflector 5 to move back and forth, thereby directing hot air to different locations of the stored grain, improving the problem of some stored grain being too dry and some not being dry, and ensuring that the hot air dries the stored grain evenly in different locations.
[0040] Example 2
[0041] This embodiment is basically the same as embodiment 1, except that:
[0042] like Figure 2-5 As shown, a wear-resistant rubber ring is fixedly connected to the outer side of the wind deflector 5. The wear-resistant rubber ring fits against the inner wall of the main wind cover 2. Friction will be generated when the wind deflector 5 moves. When the wind deflector 5 stops moving, it prevents the wind deflector 5 from being affected by the wind and moving backward.
[0043] like Figure 1-5 As shown, a hollow cylinder 6 is fitted onto the rod 4, and the rod 4 reciprocates within the hollow cylinder 6. The hollow cylinder 6 is fixedly positioned between the silo body 1 and the main air hood 2. Specifically, the hollow cylinder 6 passes through one end of the silo body 1 and the main air hood 2. The hollow cylinder 6 serves to isolate the stored grain from direct contact with the rod 4, preventing direct contact between the rod 4 and the stored grain from increasing the resistance to the movement of the rod 4.
[0044] The hollow cylinder 6 has protrusions at both ends, which are located on the outer side wall of the hopper 1 and the inner side wall of the main air hood 2, respectively. Limiting rings 7 are fitted on the protrusions. The limiting rings 7 are threadedly connected to the protrusions at both ends of the hollow cylinder 6.
[0045] A wear-resistant rubber ring is fixedly connected to the outside of the wind deflector 5. When the wind deflector 5 stops moving, the wear-resistant rubber ring is used to increase the friction with the inner wall of the main wind cover 2 to prevent the wind deflector 5 from moving on its own due to the wind force.
[0046] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
