Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and in particular to an adjustable angle baffle for a mixed-flow dryer. Background Technology

[0002] Drying equipment is often required in grain production and processing. Among them, mixed-flow heat pump dryers are widely used in the food processing industry due to their energy-saving and environmentally friendly characteristics.

[0003] A drying device is proposed in the related technology, including a heat pump dryer and a drying chamber. The air outlet of the heat pump dryer is connected to the top of the drying chamber through an air outlet duct. A support frame is provided inside the drying chamber, and an airflow distribution plate is fixedly connected to the top of the support frame. The hot air input in the air outlet duct is divided into multiple airflows after passing through the airflow distribution plate, thereby achieving uniform drying of the materials in the drying chamber.

[0004] Regarding the aforementioned technologies, since the airflow distribution plate is fixedly connected to the support frame, the airflow trajectory is fixed, which makes it easy for drying dead zones to exist, resulting in different material drying speeds, uneven drying, and affecting the drying quality of the material. Utility Model Content

[0005] To address the issues of fixed airflow paths caused by the fixed connection between the airflow distribution plate and the support frame, which can easily lead to drying dead zones, uneven material drying speeds, and inconsistent drying quality, this application provides an adjustable angle baffle for a mixed-flow dryer.

[0006] This application provides an adjustable-angle baffle for a mixed-flow dryer, employing the following technical solution:

[0007] An adjustable angle baffle for a mixed-flow dryer includes a mounting frame, a flow divider, and an adjustment mechanism. The mounting frame is installed on the top side wall of the drying chamber. A rotating rod is provided on the mounting frame along its length direction. The rotating rod is rotatably connected to the mounting frame around its own length direction. Multiple rotating rods are spaced apart along the width direction of the mounting frame. The flow divider is located on the rotating rod. The adjustment mechanism is located on the mounting frame and is used to synchronously drive all the rotating rods to reciprocate in both directions.

[0008] By adopting the above technical solution, during use, the mounting frame is installed on the top side wall of the drying chamber. When the hot air entering through the air outlet duct passes downward through the diverter plate, the adjustment mechanism drives all the rotating rods to rotate back and forth, thereby causing the diverter plate to rotate back and forth. This causes the airflow passing through the diverter plate to swing left and right, improving the uniformity of the hot airflow distribution and preventing the airflow from blowing in one fixed direction. This improves the drying effect and efficiency, and addresses the problem of the fixed connection between the airflow diverter plate and the support frame, which leads to a fixed airflow trajectory, is prone to drying dead zones, and results in uneven drying speeds and poor material drying quality.

[0009] Optionally, the middle section of the rotating rod is rectangular, and the two ends of the rotating rod are circular. The middle part of the diverter plate has an insertion hole that matches the size of the middle section of the rotating rod, and the diverter plate is sleeved on the middle part of the rotating rod through the insertion hole.

[0010] By adopting the above technical solution, the square cross-section of the rotating rod in the middle ensures that the manifold will not rotate radially after installation, thus guaranteeing the angle adjustment accuracy of the manifold. The circular cross-sections at both ends of the rotating rod facilitate rotational connection with the mounting frame, reducing friction and wear. A matching insertion hole is provided in the middle of the manifold, allowing it to be fitted onto the rotating rod, making the installation and removal of the manifold more convenient and quick, while ensuring the stability and reliability of the manifold on the rotating rod.

[0011] Optionally, the diverter plate has sharp corners on both sides.

[0012] By adopting the above technical solution, the two sides of the flow divider are set as sharp corners, which can effectively reduce the vortex phenomenon of airflow at the edge of the flow divider, reduce energy loss, and improve the efficiency of airflow guidance. At the same time, the sharp corner design helps to enhance the stability of airflow and further improve the uniformity of airflow distribution inside the dryer.

[0013] Optionally, the adjusting mechanism includes a power component and a synchronization component. The power component includes a rotary motor, a first bevel gear, a second bevel gear, and a third bevel gear. The second and third bevel gears are coaxially connected to one of the rotating rods. The rotary motor is mounted on a mounting frame. The first bevel gear is connected to the rotating shaft of the rotary motor. The first bevel gear meshes with the second and third bevel gears. The number of teeth on the first bevel gear is half the number of teeth on a full circle. The synchronization component is used to make all the rotating rods rotate synchronously.

[0014] By adopting the above technical solution, after the rotating motor starts, its rotating shaft drives the first bevel gear to rotate. Since the first bevel gear meshes with the second and third bevel gears, and the number of teeth on the first bevel gear is half of the number of teeth on a full circle, the second and third bevel gears will alternately drive the rotating rod to rotate forward and backward. In addition, the setting of the synchronization component can ensure that all rotating rods rotate synchronously, ensure the consistency of the angle adjustment of the flow divider, and improve the uniformity of airflow distribution during the drying process.

[0015] Optionally, the synchronization component includes a driving gear and a driven gear. The driving gear is connected to each rotating rod, and the driven gear is rotatably connected to a mounting frame between two adjacent rotating rods. The driven gear meshes with two adjacent driving gears.

[0016] By adopting the above technical solution, when one of the rotating rods rotates, its driving gear rotates accordingly. Through meshing transmission with the driven gear, it drives the driving gears on the adjacent rotating rods to rotate, thereby achieving synchronous rotation among multiple rotating rods. This design ensures that all diverter plates can maintain a consistent angle change, improving the uniformity of airflow distribution within the dryer.

[0017] Optionally, the mounting frame is provided with hanging ears on both sides. The hanging ears include parallel side plates and a horizontal plate that vertically connects the side plates. The side plates are provided with waist-shaped through grooves. One side plate is connected to the mounting frame by bolts, and the other side plate is connected to the top side wall of the drying chamber by bolts.

[0018] By adopting the above technical solution, the hanging ears facilitate the connection between the installation frame and the top side wall of the drying chamber. The structural design of the two side plates and the horizontal plate improves the overall strength of the hanging ears. The waist-shaped through groove allows the bolts to be adjusted within a certain range, thereby adapting to hole position deviations in different installation environments. One side plate is connected to the installation frame by bolts, making the hanging ears detachable, which is convenient for installation and maintenance.

[0019] Optionally, reinforcing ribs are provided between the side plate and the cross plate.

[0020] By adopting the above technical solution, the addition of reinforcing ribs effectively enhances the overall structural strength of the hanging ears, preventing deformation or breakage at the connection between the side plate and the cross plate due to external forces during installation or use, thereby improving the reliability and service life of the hanging ears.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The matching arrangement of multiple rotating rods, flow dividers and adjustment mechanisms allows the hot airflow through the flow dividers to continuously change direction, improving the uniformity of hot airflow distribution, thereby improving drying effect and efficiency. This improves the problem of fixed connection between the airflow divider and the support frame, which leads to a fixed airflow trajectory, making it easier to have drying dead corners, different material drying speeds, uneven drying, and affecting the quality of material drying.

[0023] 2. The coordinated arrangement of the rotating motor, the first bevel gear, the second bevel gear, and the third bevel gear enables the rotating motor to drive the first bevel gear to rotate, thereby achieving the function of driving the rotating rod to reciprocate in both directions. The structure is simple and compact, with high stability and easy to use.

[0024] 3. The sharp corners on both sides of the splitter plate help reduce airflow resistance, enhance airflow guidance, and improve energy efficiency while reducing energy consumption. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an adjustable-angle baffle for a mixed-flow dryer. (See also...) Figure 1-2The adjustable angle baffle for the mixed-flow dryer includes a mounting frame 1, a flow divider 2, and an adjustment mechanism. The mounting frame 1 is a rectangular frame structure, connected to the side walls of the top of the drying chamber via connectors. The drying chamber described in this application is the drying chamber of a Yinniu 5H-14TP grain dryer. The mounting frame 1 is located below the air inlet on the top wall of the drying chamber. The mounting frame 1 consists of an upper frame 11 and a lower frame 12, which are fixedly connected by screws 13. Semi-circular slots 14 are provided along the length of the mounting frame 1 on the side of the upper frame 11 and lower frame 12 that are close to each other. Two corresponding semi-circular slots 14 form a complete circle. In this application, five semi-circular slots 14 are evenly spaced along the width of the rectangular frame. A rotating rod 3 is coaxially rotatably connected to the semi-circular slot 14 via bearings 15. The two ends of the rotating rod 3 have circular cross-sections with radii the same as the semi-circular slot 14, while the middle cross-section of the rotating rod 3 is rectangular. The diverter plate 2 has a hole 21 in the middle that matches the cross-sectional size of the middle section of the rotating rod 3. The diverter plate 2 is tightly fitted onto the middle section of the rotating rod 3 through the hole 21. The adjustment mechanism is set on the mounting frame 1 and is used to synchronously drive all the rotating rods 3 to reciprocate in both directions.

[0032] During use, hot air is discharged downwards through the air inlet on the top wall of the drying chamber. When the hot air passes through the gap between each diverter plate 2, the airflow direction is changed and the air is divided by the diverter plate 2. At this time, the adjustment mechanism synchronously drives all the rotating rods 3 to rotate back and forth, so that the direction of the divided airflow changes cyclically, improving the uniformity of the hot airflow distribution, reducing the probability of drying dead corners during the drying process, and improving the problem of the fixed connection between the airflow diverter plate and the support frame, which leads to a fixed airflow trajectory, making it easier to have drying dead corners, different material drying speeds, uneven drying, and affecting the drying quality of the material.

[0033] To improve airflow guidance efficiency, the two sides of the flow divider 2 are designed with sharp, rounded corners. The sharp corners effectively reduce eddy currents at the edges of the flow divider 2, reducing energy loss and improving airflow guidance efficiency. At the same time, the sharp corner design helps enhance airflow stability and further improves the uniformity of airflow distribution inside the dryer.

[0034] For example, refer to Figure 1 and Figure 3The adjustment mechanism includes a power component and a synchronization component. The synchronization component ensures that the rotation of all rotating rods 3 is consistent; the power component drives any rotating rod 3 to reciprocate in both directions. In this embodiment, the synchronization component includes a driving gear 4 and a driven gear 5. The driving gear 4 is coaxially connected to each rotating rod 3, and the driven gear 5 is mounted on the mounting frame 1 between two adjacent rotating rods 3. Specifically, the driven gear 5 is rotatably connected to the mounting frame 1, and the driven gear 5 meshes with the driving gear 4 on the two closest rotating rods 3. The sequentially meshing driving gear 4 and driven gear 5 can achieve synchronous movement and realize the function of synchronous and same-direction rotation of the rotating rods 3.

[0035] The power assembly specifically includes a rotary motor 6, a first bevel gear 7, a second bevel gear 8, and a third bevel gear 9. The second bevel gear 8 and the third bevel gear 9 are coaxially connected to one of the rotating rods 3. The rotary motor 6 is bolted and fixed to the mounting frame 1. The first bevel gear 7 is connected to the rotating shaft of the rotary motor 6 coaxially. The first bevel gear 7 is a half gear, and the number of teeth of the first bevel gear 7 is half that of a full circle gear. During rotation, the first bevel gear 7 can mesh with the second bevel gear 8 and the third bevel gear 9 respectively, and at any given time, the first bevel gear 7 can only mesh with one of the second bevel gear 8 and the third bevel gear 9.

[0036] After the rotating motor 6 starts, its rotating shaft drives the first bevel gear 7 to rotate. Since the first bevel gear 7 can mesh with the second bevel gear 8 and the third bevel gear 9, and the first bevel gear 7 can only mesh with one of them at a time, the second bevel gear 8 and the third bevel gear 9 will alternately mesh with the first bevel gear 7, thereby driving the rotating rod 3 to perform periodic forward and reverse rotation. With the meshing transmission of each driving gear 4 and driven gear 5, the function of synchronously driving all the rotating rods 3 to reciprocate forward and reverse rotation can be realized. The overall structure of the adjustment mechanism of this application is stable and reliable, compact, and highly automated. It can realize the automatic reciprocating forward and reverse rotation of the diverter plate 2, improve the uniformity of hot airflow distribution, avoid drying dead zones, and is easy to use.

[0037] Reference Figure 1In this application, the connecting component includes hanging ears 10, which are disposed on both sides of the mounting frame 1 in the width direction, with two sets on each side. Each hanging ear 10 includes parallel side plates 101 and a horizontal plate 102 perpendicularly connecting the side plates 101. Reinforcing ribs 103 are welded and fixed between the side plates 101 and the horizontal plate 102, improving the overall strength of the hanging ears 10. Each side plate 101 has a waist-shaped through groove 104. A bolt passes through the waist-shaped through groove 104 on one side plate 101, and the bolt is threadedly connected to the mounting frame 1. The other side plate 101 is fixedly connected to the top side wall of the drying chamber by bolts. The hanging ears 10 allow for quick connection between the mounting frame 1 and the top side wall of the drying chamber, facilitating installation and maintenance. The waist-shaped through groove 104 allows the bolts to be adjusted within a certain range, adapting to hole position deviations under different installation environments and achieving stable fixation of the mounting frame 1.

[0038] The implementation principle of the adjustable angle baffle for the mixed-flow dryer in this application embodiment is as follows: During use, the mounting frame 1 is fixedly installed on the side walls around the top of the drying chamber by the lugs 10 and bolts. Hot air is discharged downward through the air inlet on the top wall of the drying chamber. When the hot air passes through the gap between each diverter plate 2, the airflow direction is changed and the air is diverted by the diverter plate 2. At this time, the rotating motor 6 is started to drive the first bevel gear 7 to rotate. Since the first bevel gear 7 can mesh with the second bevel gear 8 and the third bevel gear 9, and the first bevel gear 7 can only mesh with one of them at the same time, the second bevel gear 8 and the third bevel gear 9 will alternately mesh with the first bevel gear 7, thereby driving the rotating rod 3 to perform periodic forward and reverse rotation. Furthermore, since the driving gears 4 on adjacent rotating rods 3 are all meshed with the same driven gear 5, the rotation of one rotating rod 3 can synchronously drive all rotating rods 3 to rotate, thereby realizing the function of synchronously driving all rotating rods 3 to reciprocate forward and reverse rotation. This causes the direction of the split airflow to change cyclically, improving the uniformity of the hot airflow distribution, reducing the probability of drying dead zones during the drying process, and improving the problem of the fixed connection between the airflow distribution plate and the support frame, which leads to a fixed airflow trajectory, making it easier for drying dead zones to exist, resulting in different material drying speeds, uneven drying, and affecting the quality of material drying.

[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
