Description

Technical Field

[0001] This utility model relates to the field of grain drying technology, and in particular to a corner-shaped box for a grain drying tower. Background Technology

[0002] An angled box in a grain drying tower refers to a device installed inside the grain drying tower for the entry of dry hot air and the exit of humid hot air. The angled box also guides the flow of the grain during its descent. There are two types of angled boxes: an exhaust angled box and an inlet angled box. The exhaust angled box is used for the downward discharge of dry hot air, while the inlet angled box is used for the outlet of humid hot air. The dry hot air exits from the exhaust angled box and flows through the grain, then enters from the bottom of the inlet angled box along the gaps between the grain particles and exits outward, thereby achieving the drying of the grain.

[0003] In the initial stage of operation of the grain drying tower, hot dry air is discharged from the bottom of the outlet corner box and comes into contact with the grain to dry it. After contact with the grain, the hot dry air forms humid hot air, which then enters from the bottom of the inlet corner box and is discharged outward. When the grain has a high moisture content, the humid hot air also has a high moisture content. When the humid hot air comes into contact with the cooler inner wall of the inlet corner box, the moisture in the humid hot air easily condenses on the inner wall of the inlet corner box, forming condensate. After condensation, the condensate easily drips down into the grain, thus affecting the drying of the grain. Therefore, this application provides a grain drying tower corner box to meet the requirements. Utility Model Content

[0004] This utility model provides a corner box for a grain drying tower to solve the problem that in the early stage of operation of a grain drying tower, when the relatively humid hot air comes into contact with the inner wall of the corner box with a lower temperature, condensation water easily forms and drips down into the grain, thus affecting the grain drying process.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A grain drying tower with a corner-shaped box, including an air inlet box and an air outlet box, and further comprising: A heat conduction mechanism, comprising multiple heat conduction pipes fixed to the inner wall of the air outlet box, multiple heat conduction covers fixed to the outer wall of the air inlet box, the ends of the heat conduction pipes being fixedly connected to the outer wall of the heat conduction covers, and the heat conduction pipes being connected to the heat conduction covers. When hot air is discharged from the air outlet box, some of the hot air flows from the heat pipe to the heat guide cover and comes into contact with the outer wall of the air inlet box.

[0006] Preferably, a guide head is fixed to the outer wall of the air inlet box, and the top of the guide head is fixedly connected to the top of the inner wall of the heat conduction shroud. The guide head is used to guide the hot air flowing from the heat conduction pipe into the heat conduction shroud.

[0007] Preferably, the guide head has arc-shaped surfaces on opposite sides, which are used to guide the flow of hot air.

[0008] Preferably, heat exchange plates are fixed together on the outer wall of the air inlet box and the arc-shaped surface, and the heat exchange plates are located inside the heat-conducting cover.

[0009] Preferably, air guide strips are fixed on opposite sides of the heat exchange plate, the ends of the air guide strips are fixedly connected to the inner wall of the heat conduction cover, and through grooves are opened on the side of the heat conduction cover corresponding to the positions of the air guide strips.

[0010] Preferably, the air guide strip has an inclined surface, which is used to guide the flow of hot air.

[0011] Preferably, a baffle is fixed on the outer wall of the heat-conducting cover at the corresponding through groove.

[0012] Preferably, the top of the heat-conducting cover is integrally formed with an inclined portion, and the top of the inclined portion is inclined upward.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting up heat-conducting pipes and heat-conducting covers, when hot air is discharged from the air outlet box, part of the hot air flows from the heat-conducting pipes to the heat-conducting covers and comes into contact with the outer wall of the air inlet box, thereby heating the air inlet box. This prevents condensation from forming when the humid hot air comes into contact with the inner wall of the air inlet box, thus not affecting the normal drying of the grain. At the same time, when the grain comes into contact with the heat-conducting pipes and heat-conducting covers, the grain can also be heated to assist in the drying of the grain.

[0014] By setting an inclined section and a guide head, with the inclined section located at the top of the heat conduction cover, the space at the corresponding guide head of the heat conduction cover can be increased, the hot air flow rate at the guide head can be slowed down, and the heating effect of the hot air on the guide head can be improved, thereby improving the heating effect of the guide head on the air inlet box and further preventing the generation of condensate.

[0015] By installing heat exchange fins fixed to the outer wall of the air inlet box, the contact area between the hot air and the outer wall of the air inlet box is increased, thereby further improving the heating capacity of the air inlet box and preventing the generation of condensate.

[0016] By setting up air guide strips and inclined surfaces, when hot air flows inside the heat-conducting hood, it is guided by the air guide strips and can be discharged from the through-slot on the side of the heat-conducting hood. The hot air comes into contact with the grain flowing from the outer wall of the air inlet box, which not only assists in drying the grain but also heats the air inlet box, greatly reducing the possibility of condensation on the inner wall of the air inlet box. At the same time, after the hot air comes into contact with the air guide strips, it is guided by the inclined surfaces, ensuring the air guide strips' ability to intercept the hot air and reducing the possibility of the hot air passing directly through the air guide strips, thus ensuring the air guide strips' ability to guide the hot air.

[0017] By setting up a baffle, which is fixed to the corresponding slot on the outer wall of the heat-conducting cover, the grain is prevented from entering the interior of the heat-conducting cover when it flows downward on the outer wall of the air inlet box, thus ensuring the smooth flow of hot air at the slot.

[0020] The corner box of a grain drying tower provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0021] like Figures 1-4 As shown, an embodiment of this utility model provides a corner-shaped box for a grain drying tower, including an air inlet box 1 and an air outlet box 2, and further comprising: The heat conduction mechanism 3 includes multiple heat conduction pipes 4 fixed to the inner wall of the air outlet box 2, and multiple heat conduction covers 5 fixed to the outer wall of the air inlet box 1. The ends of the heat conduction pipes 4 are fixedly connected to the outer wall of the heat conduction covers 5, and the heat conduction pipes 4 and the heat conduction covers 5 are connected in communication. When hot air is discharged from the air outlet box 2, some of the hot air flows from the heat pipe 4 to the heat shroud 5 and comes into contact with the outer wall of the air inlet box 1. Most of the hot air in the air outlet box 2 directly acts on the grain to achieve the main drying. Some of the hot air is transported to the heat shroud 5 through the heat pipe 4, comes into contact with the outer wall of the air inlet box 1 and conducts heat, which raises the temperature of the inner wall of the air inlet box 1. This prevents the humid hot air from forming condensation on the inner wall of the air inlet box 1 and ensures the normal drying of the grain. At the same time, when the flowing grain comes into contact with the heat pipe 4 and the heat shroud 5, it can absorb the residual heat from both of them to achieve auxiliary drying and greatly improve the overall drying efficiency.

[0022] like Figure 2 and Figure 4As shown in this embodiment, a guide head 7 is fixed on the outer wall of the air inlet box 1. The top of the guide head 7 is fixedly connected to the top of the inner wall of the heat conduction cover 5. The guide head 7 is used to guide the hot air flowing from the heat conduction pipe 4 into the heat conduction cover 5. The guide head 7 plays a guiding role in the hot air entering the heat conduction cover 5, thereby improving the smoothness of the hot air flow in the heat conduction cover 5.

[0023] like Figure 4 As shown in this embodiment, arc-shaped surfaces 8 are provided on opposite sides of the guide head 7. The arc-shaped surfaces 8 are used to guide the flow of hot air. The arc-shaped surfaces 8 reduce the flow resistance of hot air and guide the hot air to diffuse smoothly to both sides, so that the hot air can make more sufficient contact with the outer wall of the air inlet box 1, thereby improving the heating efficiency. At the same time, the arc-shaped structure avoids the formation of vortices in the hot air at the guide head 7, ensuring a stable hot air flow rate, further ensuring uniform heat conduction, and enhancing the effect of preventing condensation.

[0024] like Figure 4 As shown in this embodiment, heat exchange plates 12 are fixed on both the outer wall of the air inlet box 1 and the arc-shaped surface 8. The heat exchange plates 12 are located inside the heat-conducting cover 5. The heat exchange plates 12 greatly increase the contact area between the hot air and the air inlet box 1, improve the heat exchange efficiency, and enable the outer wall of the air inlet box 1 to heat up quickly, effectively suppressing the formation of condensate.

[0025] like Figure 3 and Figure 4 As shown in this embodiment, air guide strips 9 are fixed on opposite sides of the heat exchange plate 12. The ends of the air guide strips 9 are fixedly connected to the inner wall of the heat conduction cover 5. A through groove is opened on the side of the heat conduction cover 5 corresponding to the position of the air guide strips 9. The air guide strips 9 intercept part of the hot air, force the hot air to flow along the air guide strips 9 to the through groove and discharge it from the through groove. The hot air discharged from the through groove heats the air inlet box 1 and at the same time makes full contact with the grain flowing downward on the outer wall of the air inlet box 1, thereby achieving auxiliary drying of the grain, further reducing the possibility of condensation and improving drying efficiency.

[0026] like Figure 4 As shown in this embodiment, the air guide strip 9 is provided with an inclined surface 10. The inclined surface 10 is used to guide the flow of hot air. The inclined surface 10 prevents the hot air from directly passing over the air guide strip 9, ensuring that the hot air flows along a preset path and improving the air guiding reliability of the air guide strip 9.

[0027] like Figure 3 As shown in this embodiment, a baffle 11 is fixed on the outer wall of the heat conduction cover 5 corresponding to the through groove. The baffle 11 can prevent the grain flowing downward from the outer wall of the air inlet box 1 from entering the interior of the heat conduction cover 5, so as to avoid the through groove being blocked by the grain and ensure that the hot air is discharged smoothly.

[0028] like Figure 4As shown in this embodiment, the top of the heat conduction cover 5 is integrally formed with an inclined portion 6. The top of the inclined portion 6 is inclined upward. The inclined portion 6 increases the space at the guide head 7, slows down the hot air flow rate, and allows the hot air to fully contact the guide head 7, thereby improving the heating effect and enhancing the anti-condensation ability of the air inlet box 1.

[0029] Working principle: Hot air generated by the hot air furnace in the grain drying tower enters the air outlet box 2. Most of the hot air directly acts on the grain to achieve the main drying. Some of the hot air will flow into multiple heat-conducting pipes 4 on the inner wall of the air outlet box 2 and be transported to the corresponding heat-conducting cover 5 on the outer wall of the air inlet box 1 through the heat-conducting pipes 4 to form auxiliary heating. After the hot air enters the heat-conducting cover 5, it first contacts the guide head 7 on the outer wall of the air inlet box 1. The arc-shaped surfaces 8 on both sides of the guide head 7 guide the hot air to flow smoothly to both sides. The inclined part 6 at the top of the heat-conducting cover 5 is inclined upward, which increases the space at the guide head 7, slows down the hot air flow rate, and allows the hot air to fully contact the guide head 7, improving the heating effect of the guide head 7. Then, the heat is conducted to the air inlet box 1 through the guide head 7. At the same time, the heat exchange plate 12 fixed on the outer wall of the air inlet box 1 and the arc-shaped surface 8 increases the contact area between the hot air and the air inlet box 1, further improving the heating efficiency and raising the temperature of the inner wall of the air inlet box 1. This prevents the humid hot air from forming condensate on the inner wall of the air inlet box 1, ensuring the normal drying of the grain. When hot air flows inside the heat-conducting cover 5, some of the hot air will be intercepted by the air guide strips 9 on both sides of the heat exchange plate 12. The inclined surface 10 on the air guide strip 9 prevents the hot air from directly passing over the air guide strip 9, ensuring that the hot air flows along the air guide strip 9 to the through groove on the side of the heat-conducting cover 5. During this process, the hot air not only continuously heats the air inlet box 1, but also comes into contact with the grain flowing downward on the outer wall of the air inlet box 1, assisting in drying the grain and further reducing the possibility of condensation on the inner wall of the air inlet box 1. The baffle 11 at the through groove on the outer wall of the heat-conducting cover 5 can prevent flowing grain from entering the interior of the heat-conducting cover 5 and blocking the through groove, thereby ensuring that hot air is discharged smoothly. At the same time, the grain can also absorb heat from the heat-conducting pipe 4 and the heat-conducting cover 5 during the flow process, thereby achieving auxiliary drying and improving the overall drying efficiency.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
