Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying machine technology, specifically to a corner box structure for a drying section that prevents bridging. Background Technology
[0002] Currently, the mixed-flow drying layer structure on the market uses a solid, angular box structure. When drying rice and wheat with high moisture content or high impurities, these grains are prone to bridging, preventing effective flow of grain inside the machine. This results in slow drying speeds, hindering the drying process. Furthermore, over time, the grain accumulated due to bridging can become moldy, affecting grain quality. Figure 1 As shown, combined with Figure 2 The original machine, after being filled with rice, had hot air enter through an opening on one side of the box, pass through the rice, and exit through an opening on the other side. If the rice had high moisture or impurity content, the flow of the rice pressing on top of the corner box A would be reduced, causing the rice below the drying layer to be squeezed by the rice above, or even to not flow at all, resulting in bridging, which would affect the dehydration of the grains and lead to undesirable results such as incomplete drying and mold growth. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a corner box structure for an anti-bridging drying section, solving the technical problem that bridging within the drying layer affects the drying of grains.
[0004] This utility model is achieved through the following technical solution:
[0005] A corner box structure for preventing bridging in a drying section includes: a box body and multiple corner boxes. The multiple corner boxes are arranged in parallel and evenly installed in several rows inside the box body. The side plates connected to both ends of the box body and the corner boxes are respectively an air inlet plate and an air outlet plate. Several rows of air inlets are opened on the air inlet plate. One end of one row of corner boxes is connected to the air inlet of that row and the other end is connected to the air outlet plate. Several rows of air outlets are opened on the air outlet plate. One end of another row of corner boxes is connected to the air outlet and the other end is connected to the air inlet plate. Each row of air inlets and each row of air outlets are staggered at a certain height. The shell of each corner box is provided with fish scale-like staggered mesh holes.
[0006] Preferably, each row of air inlets and each row of air outlets are arranged at equal intervals in the vertical direction.
[0007] Preferably, both ends of the angular box are horizontally connected to the air inlet plate and the air outlet plate, and flange connections are used at the connection points.
[0008] Preferably, the top of the angular box is arc-shaped, and the top is provided with a fish-scale-like interlaced mesh.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] This invention features a fish-scale-like interlaced mesh on the shell of a angular box. After hot air enters through the air inlet, part of it passes through the rice grains and exits through the air outlet, while the other part passes through the fish-scale-like mesh on the shell of the angular box, through the grain layer, and then exits through the air outlet. This can blow through the grains pressed on top of the angular box and suspend them, allowing the grains to circulate more smoothly, which not only improves the dehydration speed but also eliminates bridging.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Figure 1-8 A bridging-resistant corner box structure for a drying section is shown, comprising a housing 1 and multiple corner boxes 2. The multiple corner boxes 2 are arranged in parallel and evenly installed in several rows inside the housing 1. The side plates connecting the two ends of the housing 1 and the corner boxes 2 are respectively an air inlet plate 101 and an air outlet plate 102. The air inlet plate 101 has several rows of air inlets 1011. One end of one row of corner boxes 2 is connected to the row of air inlets 1011 and the other end is connected to the air outlet plate 102. The air outlet plate 102 has several rows of air outlets 1021. One end of another row of corner boxes 2 is connected to the row of air outlets 1021 and the other end is connected to the air inlet plate 101. Each row of air inlets 1011 and each row of air outlets 1021 are staggered with a certain height difference. To effectively prevent grains from bridging inside the drying chamber, the shell of the corner box 2 in the drying section of the mixed-flow dryer (i.e., inside the chamber 1) is provided with a densely packed, intersecting, fish-scale-like mesh 201. During drying and ventilation, the rice in the drying layer can be suspended in a suspended state under the blowing of the fan, so that the rice below the drying layer is not squeezed by the rice above, thus preventing bridging and improving the dehydration speed and promoting the drying effect on the grains.
[0023] like Figure 7 As shown, each row of air inlets 1011 and each row of air outlets 1021 are arranged at equal intervals in the vertical direction so that hot air can flow evenly inside the box 1, thereby enhancing the drying effect on the grain.
[0024] Preferably, both ends of the corner box 2 are horizontally connected to the air inlet plate 101 and the air outlet plate 102, forming a smooth air duct. Flange connections are used at all these joints to ensure sealing performance and prevent air leakage. Figure 6 The corner box 2 can be welded from the shell and the flanges 202 at both ends, and then connected to the corresponding connection points of the air inlet plate 101 and the air outlet plate 102 with screws.
[0025] Generally, the top of the angular box 2 is designed as a triangular pyramid. As one embodiment of this utility model, for example... Figure 8The top of the angular box 2 is constructed in an arc shape, and the top is provided with fish scale-like interlaced mesh 201. The arc shape of the top helps the rice pressed on the angular box to flow more easily and is less likely to cause bridging, which further promotes the drying of the grain.
[0026] The working principle of this utility model:
[0027] This utility model designs a fish-scale-like interlaced mesh 201 (e.g., on the shell of the angular box 2) Figure 6 ), combined Figures 2-4 as well as Figure 7 Hot air enters through the air inlet 1011 of the air inlet plate 101, and some of the hot air is like... Figure 7 As indicated by arrow a, it passes through the rice grains and exits from the air outlet 1021 of the air outlet plate 102, with some of the hot air... Figure 7 As indicated by arrow b, the hot air passes through the fish-scale mesh 201 on the shell of the angular box 2, through the grain layer, and then exits through the air outlet 1021 of the air outlet plate 102. Since the hot air enters the drying layer by being blown in by a fan, the air volume and air pressure entering the drying layer are relatively large. The hot air in the direction indicated by arrow b can blow through the grain pressed above the angular box 2 and suspend it, making the grain loose from its original compressed state and allowing the grain to flow more smoothly. This not only improves the dehydration speed but also prevents bridging.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
