Description
Technical Field
[0001] This utility model relates to the field of grain drying tower technology, and in particular to a grain drying tower with uniform heating. Background Technology
[0002] Grain drying towers are large-scale vertical equipment for grain drying, consisting of a heating system, a ventilation system, a conveying system, and a control system. During operation, hot air is introduced into the tower through a hot air furnace to contact the grain to be dried, removing moisture and reducing its moisture content to meet the needs of safe storage, transportation, and subsequent processing. They are used for post-harvest processing of grains such as wheat, corn, and rice. The equipment is symmetrically equipped with air inlets and outlets. An air inlet pipe is installed at the air inlet, and an air outlet pipe is installed at the air outlet. The heated high-temperature gas enters the tower through the air inlet pipe and exits from the bottom of the air inlet pipe, contacting the grain. Water vapor generated during the grain drying process enters from the bottom of the air outlet pipe and then exits through the air outlet.
[0003] The high-temperature gas entering through the air inlet blows directly onto the end of the air inlet pipe, making the pressure at the end away from the air inlet higher than the pressure at the air inlet. The grain on the side away from the air inlet comes into contact with more high-temperature gas, resulting in a greater drying effect for the grain on the side away from the air inlet than for the grain on the side closer to the air inlet. This leads to uneven grain drying. Therefore, this application provides a grain drying tower with uniform heating to meet the requirements. Utility Model Content
[0004] This invention provides a grain drying tower with uniform heating to solve the problem of insufficient uniformity in grain drying.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A grain drying tower with uniform heating includes a tower body, wherein a plurality of air outlets and air inlets are respectively opened on opposite sides of the tower body, the air outlets and air inlets being staggered vertically, and a plurality of air outlet pipes and air inlets are fixed on the inner wall of the tower body, the air inlets communicating with the air inlets and the air outlet pipes communicating with the air outlets, and further includes: The dispersion mechanism includes a plurality of baffles fixed to the inner wall of the air inlet pipe, wherein the plurality of baffles increase in height sequentially in the direction from the air inlet to the air outlet. The high-temperature gas introduced through the air inlet passes through several baffles and is dispersed by the baffles.
[0006] Preferably, the baffle is inclined toward the air inlet.
[0007] Preferably, a second baffle is fixed to the top of the first baffle, and the second baffle is inclined.
[0008] Preferably, the tilt angle of the second baffle is greater than the tilt angle of the first baffle.
[0009] Preferably, a guide plate is fixed between adjacent baffles, and the surface of the guide plate has through holes, with the side of the guide plate closer to the air inlet being lower than the side farther from the air inlet.
[0010] Preferably, the inner walls of the through hole are provided with inclined surfaces on opposite sides, with the opening being larger on the side of the through hole closer to the air inlet and smaller on the side of the through hole farther from the air inlet.
[0011] Preferably, a reinforcing component is provided at the bottom of the first baffle, which is used to reinforce the first baffle.
[0012] Preferably, the reinforcement component includes a horizontal plate fixed to the bottom of the baffle, the horizontal plate being fixed below the air intake pipe, and side plates being fixed to both ends of the horizontal plate. The side plates are fixed to the surface of the air intake pipe, and the surface of the side plates is provided with a second inclined surface.
[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting up baffle 1, the high-temperature gas introduced from the air inlet passes through several baffle 1 in sequence. The baffle 1 gradually guides the high-temperature gas to the bottom of the air inlet pipe, making the distribution of high-temperature gas more uniform, thereby improving the uniformity of grain drying.
[0014] By setting up a second baffle, the high-temperature gas is guided more effectively, allowing it to flow smoothly to the baffle. The first baffle is also set at an angle, which further enhances its ability to guide the high-temperature gas, thereby improving the uniformity of grain drying.
[0015] By setting up guide plates and through holes, the high-temperature gas flowing downwards along the baffle flows onto the guide plates, which guide the flow of the high-temperature gas, allowing it to be discharged more evenly from the through holes. This enables the high-temperature gas to contact the grain more evenly, thereby further improving the uniformity of grain drying at the bottom of the air inlet pipe.
[0016] By setting the first inclined plane, the high-temperature gas flow rate is faster on the side of the through hole away from the air inlet and slower on the side closer to the air inlet. The setting of the first inclined plane makes the opening of the through hole larger on the side closer to the air inlet and smaller on the side farther from the air inlet, thereby making the high-temperature gas discharged from the through hole more uniform.
[0017] By setting up reinforcing components, the horizontal plate and side plate can improve the connection strength of the baffle one, preventing the baffle one from falling off the inner wall of the air inlet pipe during use, thus improving its durability. The setting of the second slope makes the top of the side plate pointed, which can guide the grain and prevent the second slope from affecting the flow of the grain. Attached Figure Description

[0020] The following is a detailed description of a uniformly heated 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; those skilled in the art can also use other alternative methods to implement some known technologies; and 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 1-5 As shown, an embodiment of this utility model provides a grain drying tower with uniform heating, including a tower body 1. Several air outlets and air inlets are respectively opened on opposite sides of the tower body 1, and the air outlets and air inlets are staggered vertically. Several air outlet pipes 3 and air inlet pipes 2 are fixed to the inner wall of the tower body 1. The air inlet pipes 2 communicate with the air inlet, and the air outlet pipes 3 communicate with the air outlet. The tower also includes: The dispersion mechanism 4 includes a plurality of baffles 5 fixed to the inner wall of the air inlet pipe 2, and the plurality of baffles 5 increase in height in sequence in the direction from the air inlet to the air outlet. High-temperature gas introduced through the air inlet passes through several baffles 5 in sequence and is dispersed by the baffles 5. The tower body 1 provides a closed space for grain drying. The air inlet allows high-temperature gas to enter, and the air outlet allows moisture to be discharged. The staggered arrangement of the upper and lower parts improves the efficiency of gas-grain contact. The air inlet pipe 2 transports high-temperature gas, and the air outlet pipe 3 discharges moisture. The baffles 5, which are raised in sequence, gradually guide the high-temperature gas to the area below the air inlet pipe 2, breaking the concentrated flow of gas and making the gas evenly distributed in the air inlet pipe 2. This allows the discharged gas to come into more comprehensive contact with the grain and improves the uniformity of drying.
[0022] like Figure 5As shown in this embodiment, the baffle 5 is inclined toward the air inlet. The inclined baffle 5 enhances the guiding ability of high-temperature gas, allowing the gas to flow smoothly along the inclined surface to the bottom of the air inlet pipe 2, avoiding turbulence caused by the gas impacting the baffle 5, reducing gas flow resistance, ensuring that the gas is stably dispersed under the action of the baffle 5, further improving the uniformity of gas distribution, and ensuring consistent grain drying effect.
[0023] like Figure 5 As shown in this embodiment, a second baffle 6 is fixed to the top of the first baffle 5. The second baffle 6 is inclined and guides the high-temperature gas entering the intake pipe 2 in advance, quickly directing the gas to the first baffle 5, preventing the gas from accumulating at the top of the intake pipe 2. Together with the first baffle 5, it forms a multi-stage guiding structure, improving the smoothness of gas flow.
[0024] like Figure 5 As shown in this embodiment, the tilt angle of baffle 2 6 is greater than that of baffle 1 5. The larger tilt angle of baffle 2 6 allows it to quickly receive the high-speed gas that has just entered the intake pipe 2 and change its flow direction, guiding the gas to smoothly transition to baffle 1 5 with a smaller tilt angle.
[0025] like Figure 5 As shown in this embodiment, a guide plate 7 is fixed between adjacent baffles 5. The surface of the guide plate 7 is provided with through holes 8. The side of the guide plate 7 near the air inlet is lower than the side away from the air inlet. The guide plate 7 is inclined to guide the gas dispersed by the baffles 5 to flow downward along the plate surface, avoiding the accumulation of gas between adjacent baffles 5. The through holes 8 allow the gas to be discharged evenly to the bottom of the air inlet pipe 2, ensuring that different areas at the bottom of the air inlet pipe 2 are uniformly discharged and fully contact the falling grain, thereby improving the uniformity of grain drying at the bottom of the air inlet pipe 2.
[0026] like Figure 5 As shown in this embodiment, inclined surfaces 9 are provided on opposite sides of the inner wall of the through hole 8. The opening of the through hole 8 is larger on the side closer to the air inlet and smaller on the side farther away from the air inlet. The flow rate is slower and the opening is larger on the side closer to the air inlet, while the flow rate is faster and the opening is smaller on the side farther away. The inclined surfaces 9 are adapted to this difference in flow rate, so that the flow rate of gas with different flow rates tends to be consistent when passing through the through hole 8, avoiding uneven distribution of discharged gas due to different flow rates, ensuring uniform contact between gas and grain, and further improving drying uniformity.
[0027] like Figures 3-5 As shown in this embodiment, a reinforcing component 10 is provided at the bottom of the baffle 5. The reinforcing component 10 is used to reinforce the baffle 5. The reinforcing component 10 enhances the connection strength between the baffle 5 and the air inlet pipe 2, resists the impact of high temperature gas and the collision force when the grain falls, prevents the baffle 5 from falling off or deforming from the inner wall of the air inlet pipe 2, ensures the long-term stable operation of the dispersing mechanism 4, and improves the service life of the equipment.
[0028] like Figures 3-5 As shown in this embodiment, the reinforcement component 10 includes a horizontal plate 11 fixed to the bottom of the baffle 5. The horizontal plate 11 is fixed below the air intake pipe 2. Side plates 12 are fixed to both ends of the horizontal plate 11. The side plates 12 are fixed to the surface of the air intake pipe 2. The surface of the side plates 12 is provided with a second inclined surface 13. The horizontal plate 11 and the side plates 12 fix the baffle 5 from the bottom, which greatly improves the structural stability of the baffle 5. The second inclined surface 13 makes the top of the side plate 12 pointed, which guides the falling grain to flow smoothly and avoids the grain from accumulating at the side plate 12.
[0029] Working principle: High-temperature gas enters the inlet pipe 2 through the inlet hole of tower body 1. The gas first contacts several baffles 5 on the inner wall of the inlet pipe 2. The baffles 5 gradually guide the high-temperature gas to the bottom of the inlet pipe 2, realizing the initial dispersion of the gas. During the gas flow, the baffle 2 6 at the top of the baffle 1 5 further guides the gas flow, allowing the gas to flow smoothly downwards from the baffle 1 5 and improving the smoothness of gas dispersion. The gas guided by the baffle 5 flows to the guide plate 7 between the adjacent baffles 5, flows along the surface of the guide plate 7 and is discharged from the through hole 8. The inclined surface 9 of the inner wall of the through hole 8 makes the orifice larger on the side closer to the air inlet and smaller on the side farther away, balancing the gas flow rate and ensuring that the gas is discharged more evenly from the through hole 8. The uniformly dispersed high-temperature gas is discharged from the air inlet pipe 2 and comes into full contact with the grain falling from the top of the tower body 1 to dry the grain evenly. At the same time, the air outlet pipe 3 on the other side of the tower body 1 discharges the moisture generated during drying. During the fall of the grain, when it encounters the side plate 12 of the reinforcement component 10, the pointed structure of the inclined surface 13 guides the grain to flow smoothly and avoids grain accumulation. The horizontal plate 11 enhances the installation stability of the baffle 5 and ensures that the gas dispersion process is continuously effective. After being uniformly heated and dried, the grain continues to fall and is eventually discharged from the bottom of tower 1, completing the drying process.
[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.
