Description

Technical Field

[0001] This utility model relates to the technical field of grain drying equipment, and in particular to an air regulating mechanism for a grain drying tower. Background Technology

[0002] Grain drying typically takes place inside a drying tower. The drying tower has multiple drying chambers, each containing several angled tubes. Some of these tubes are connected to an air inlet channel, while others are connected to an air outlet channel. The bottom of each angled tube has an opening. Heated air enters the tube through the air inlet channel, heating its walls, then escapes from the opening at the bottom and flows upwards, entering again through the opening at the bottom of the next layer of angled tubes, and finally exiting through the air outlet channel. The grain moves slowly downwards within the drying chamber, and the continuously flowing hot air dries the grain and carries away the resulting moisture from the drying chamber.

[0003] However, existing drying towers have certain shortcomings: hot air enters the drying layer from one side of the air inlet and rises rapidly, making it difficult to quickly and evenly diffuse to the other side of the drying tower. This causes the grain near the air inlet to dry too quickly, and may even lead to localized excessively high temperatures due to heat accumulation, while the grain away from the air inlet is difficult to dry sufficiently, resulting in uneven drying of the grain within the same drying layer. Therefore, this application provides an air regulating mechanism for a grain drying tower to meet these requirements. Utility Model Content

[0004] This invention provides an air regulating mechanism for a grain drying tower to solve the problem of uneven grain drying within the same drying layer.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An air regulating mechanism for a grain drying tower includes a horizontal plate fixedly installed inside an angled tube. A first air guide plate with a size adapted to the angled tube is fixedly installed at one end of the horizontal plate, and an air guide port is provided in the middle of the horizontal plate. An air distribution plate is fixedly installed inside a corner tube and located below a horizontal plate. The air distribution plate has several air outlets arranged along the diagonal direction of the air distribution plate. An air guide plate is fixedly installed on the upper surface of the air distribution plate, and the top of the air guide plate is fixed to the horizontal plate. The air guide plate is used to connect the air guide port to each air outlet to form several independent channels.

[0006] Preferably, the air distribution plate includes a baffle, the upper surface of which has two symmetrical arc-shaped guide surfaces, both of which are concave arcs, and the connection point of the two arc-shaped guide surfaces is located at the center of the air inlet.

[0007] Preferably, the air guide plate includes a first side plate, a plurality of second side plates and a third side plate connected in sequence, and the bottom ends of all of them are fixed on the arc-shaped guide surface, and the air guide port is independently connected to each air outlet through the first side plate, the second side plate and the third side plate; The first and second side plates are both U-shaped structures, and the third side plate is an L-shaped structure. The third side plate is also fixed to the angular tube.

[0008] Preferably, an angled frame is also fixedly installed on the upper surface of the horizontal plate, with a gap between its outer surface and the inner surface of the angled tube. One end of the angled frame is spaced from the first air guide plate, and the other end is closed with the horizontal plate.

[0009] Preferably, a second air guide plate is also fixedly installed inside the angled frame. The second air guide plate is fixedly installed on the horizontal plate and is located on the side of the air guide port away from the first air guide plate.

[0010] Preferably, the side of the first air guide plate facing the second air guide plate is an arc-shaped surface.

[0011] Preferably, the side of the second air guide plate facing the first air guide plate is an arc-shaped surface.

[0012] Preferably, the end of the angled frame that closes with the horizontal plate has an arc-shaped structure.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, through the horizontal plate and air distribution plate set inside the corner tube, after the hot air enters from the hot air channel and passes through the air guide, it is guided by the air guide plate and distributed to each air outlet, and then evenly distributed into the drying layer. The hot air no longer rushes out from the bottom opening of the corner tube in a concentrated manner, but is evenly distributed to each area. Therefore, it can avoid the problem of uneven heating of grain in the drying layer caused by concentrated hot air, effectively eliminate the problem of grain being too dry and too hot on the side near the air inlet channel, while the side far from the air inlet channel is not dried enough, and significantly improve the uniformity of drying.

[0014] By setting up an angled frame inside the angled tube, the flow path of hot air before entering the drying layer is optimized. After entering through the air inlet channel, the hot air first moves to the end away from the air inlet channel inside the angled tube, and then flows to the air guide. This process ensures that the angled tube is fully heated, avoiding the problem of uneven heating on the side of the angled tube away from the air inlet channel due to less contact with hot air. This ensures that the grain can be fully heated when it comes into contact with the angled tube. Attached Figure Description

Detailed Implementation

[0018] The following is a detailed description of an air regulating mechanism for a grain drying tower provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement the invention. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0019] like Figures 1-4As shown, an embodiment of this utility model provides an air regulating mechanism for a grain drying tower, including a horizontal plate 1, fixedly installed inside an angled tube, a first air guide plate 6 with a size adapted to the angled tube fixedly installed at one end of the horizontal plate 1, and an air guide port 2 opened in the middle of the horizontal plate 1; an air distribution plate 3, fixedly installed inside the angled tube and located below the horizontal plate 1, the air distribution plate 3 has several air outlets 4 arranged along the diagonal direction of the air distribution plate 3; and an air induced plate 5, fixedly installed on the upper surface of the air distribution plate 3, with the top end of the air induced plate 5 fixed to the horizontal plate 1, the air induced plate 5 being used to connect the air guide port 2 to each air outlet 4 respectively, to form several independent air induced plates 4. The angled tubes are installed in the drying chamber of the drying tower, at the air inlet and outlet channels. The air regulating mechanism is installed inside the angled tube located at the air inlet channel. The first air guide plate 6 is located on the side away from the air inlet channel. After the hot air enters through the air inlet channel, it enters the angled tube, then descends through the air guide port 2 in the middle of the horizontal plate 1, and then leaves the angled tube through each air outlet 4 guided by the air guide plate 5. It then enters the drying chamber and rises, then contacts the downward flowing grain, causing the grain to be heated and dried. Finally, it enters the outlet channel from the angled tube on the upper layer without the air regulating mechanism, thus leaving the drying chamber. Figure 3 As shown, since the air outlets 4 are distributed diagonally on the air distribution plate 3, and the hot air enters from the middle position above the air distribution plate 3, after being distributed by the air distribution plate 3 and the air guide plate 5, it will be discharged to both sides of the middle of the air distribution plate 3, and then enter the different air outlets 4 on both sides through the air guide plate 5. This makes the air volume of the air outlets 4 near the air inlet channel and far from the air inlet channel approximately the same, and evenly distributed to different positions, thereby improving the uniformity of grain drying.

[0020] like Figure 3 As shown in this embodiment, the air distribution plate 3 includes a baffle 31. The upper surface of the baffle 31 has two symmetrical arc-shaped guide surfaces 31a, and both arc-shaped guide surfaces 31a are concave arcs. The connection point of the two arc-shaped guide surfaces 31a is located at the center of the air guide port 2. After the hot air passes through the air guide port 2, it flows through the channel formed by the horizontal plate 1, the baffle 31, and the air guide plate 5 to the air outlet 4 for discharge. The arc-shaped guide surface 31a is more conducive to the flow of hot air.

[0021] like Figure 3As shown in this embodiment, the air guide plate 5 includes a first side plate 51, several second side plates 52, and a third side plate 53 connected in sequence, and the bottom ends of all of them are fixed on the arc-shaped guide surface 31a. The air guide port 2 is independently connected to each air outlet 4 through the first side plate 51, the second side plate 52, and the third side plate 53. The first side plate 51 and the second side plate 52 are both U-shaped structures, and the third side plate 53 is an L-shaped structure. The third side plate 53 is also fixed to the corner tube. In the figure, the two corners of the first side plate 51 and the second side plate 52 are aligned near the middle of the baffle 31. The third side plate 53 and the corner tube form a channel. This allows the hot air to be distributed more evenly into the channels of the first side plate 51, the second side plate 52, and the channel formed by the third side plate 53 and the corner tube when it descends from the air guide port 2 and contacts the baffle 31. This allows the hot air to be discharged from each air outlet 4, achieving a uniform distribution effect.

[0022] like Figure 1 and Figure 2 As shown in this embodiment, an angled frame 7 is also fixedly installed on the upper surface of the horizontal plate 1. There is a gap between its outer surface and the inner surface of the angled tube. One end of the angled frame 7 is spaced from the first air guide plate 6, and the other end is closed to the horizontal plate 1. Typically, the angled tube is made of metal, has good thermal conductivity, and also performs a certain drying function. After hot air enters, contact with the angled tube will heat it. However, because the part of the angled tube furthest from the air inlet channel receives less airflow, while the grain in contact with the surface of the angled tube has a greater heat requirement, this… This results in insufficient heating at the end of the corner tube that is far from the air inlet channel, even if the corner tube has good thermal conductivity. In this embodiment, after the hot air enters, it first flows through the gap between the corner tube and the corner frame 7. After contacting the first air guide plate 6, it is guided into the cavity formed by the corner frame 7 and the horizontal plate 1, and then escapes from the air guide port 2 in the middle of the horizontal plate 1. During this process, the hot air fully contacts all parts of the corner tube, so that the corner tube is heated evenly, avoiding insufficient heating at the end of the corner tube that is far from the air inlet channel, thereby further improving the uniformity of drying.

[0023] like Figure 4 As shown in this embodiment, a second air guide plate 8 is also fixedly installed inside the corner frame 7. The second air guide plate 8 is fixedly installed on the horizontal plate 1 and is located on the side of the air guide port 2 away from the first air guide plate 6. The function of the second air guide plate 8 is to prevent hot air from flowing past the air guide port 2 towards the air inlet channel after entering the corner frame 7.

[0024] like Figure 4 As shown, in this embodiment, the side of the first air guide plate 6 facing the second air guide plate 8 is an arc-shaped surface, and the side of the second air guide plate 8 facing the first air guide plate 6 is an arc-shaped surface, so as to improve the guiding effect of hot air.

[0025] like Figure 4 As shown in this embodiment, the end of the corner frame 7 that is closed with the horizontal plate 1 is an arc-shaped structure to avoid large flow rate loss and to allow hot air to smoothly enter the gap between the corner tube and the corner frame 7.

[0026] Working principle: The air regulating mechanism is installed in the corner tube connected to the air inlet channel. In the working state, after the hot air enters through the air inlet channel, it first flows to the air guide 2, and then passes through the air guide 2 and the air guide plate 5 in sequence to reach each air outlet 4. Then it enters the drying chamber from the air outlet 4, exchanges heat with the grain, and then enters the air outlet channel from the corner tube above the corner tube and leaves. Specifically, when hot air enters, it first flows through the gap between the corner tube and the corner frame 7, and is guided into the corner frame 7 by the first air guide plate 6. Then it reaches the air guide port 2, and is guided again by the second air guide plate 8 so that the hot air escapes from the air guide port 2. Thus, it is evenly released into the drying chamber through the distribution of the first side plate 51, the second side plate 52, and the third side plate 53.

[0027] 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.
