Technical Field
[0001] This utility model belongs to the technical field of drying equipment, specifically a corrugated baffle plate type anti-sticking material lifting drying equipment. Background Technology
[0002] In the field of material drying, the anti-sticking and lifting performance is one of the important indicators for measuring the efficiency and quality of drying equipment. At present, some drying equipment based on the traditional baffle structure design has appeared on the market. However, these equipment are prone to problems such as material adhesion, accumulation and insufficient heat exchange in actual operation. In addition, the internal structure of the equipment is complex and difficult to clean and maintain.
[0003] For example, some existing drying equipment uses multi-layer baffles to achieve material lifting functionality. Its structure typically includes a fixed support, baffle assemblies, and a drive unit. The baffle assemblies are bolted to the inner wall of the support, and their surfaces are often flat. However, this design easily leads to material retention when handling high-humidity or high-viscosity materials, affecting drying efficiency. Furthermore, the lack of optimized design on the baffle surface further exacerbates material adhesion. These factors indicate that existing technologies have certain limitations in anti-sticking and lifting performance.
[0004] Therefore, we have made improvements to this and proposed a wave-shaped baffle plate type anti-sticking material drying equipment. Utility Model Content
[0005] The purpose of this invention is to solve the problems of material adhesion, accumulation, and insufficient heat exchange caused by unreasonable design of the baffle plate surface when the existing drying equipment processes high humidity or high viscosity materials. At the same time, it improves the shortcomings of complex internal structure and difficult cleaning and maintenance of the equipment.
[0006] To achieve the aforementioned objectives and address the problems, this utility model provides a corrugated baffle-type anti-sticking material lifting and drying device, comprising a main frame, a corrugated baffle assembly, and a driving device. The corrugated baffle assembly is installed on the inner wall of the main frame and is driven by the driving device to achieve uniform material distribution and efficient heat exchange. The corrugated baffle assembly includes several corrugated baffle units, each with multiple groove structures on its surface, the groove structures being alternately distributed along the crests and troughs of the corrugated baffle unit. The corrugated baffle units are fixed to the inner wall of the main frame by connectors, and a lifting channel is formed between adjacent corrugated baffle units.
[0007] The corrugated baffle unit is formed by stamping metal sheet, and the radii of curvature of its crests and troughs are optimized according to the material's flowability to reduce the possibility of material stagnation. The depth and width of the groove structure are proportional to the wavelength of the corrugated baffle unit, specifically between 1:5 and 1:8, to ensure that the material can be effectively guided into the lifting channel during flow. The surface of the corrugated baffle unit is coated with an anti-stick coating made of polytetrafluoroethylene (PTFE), which has a low coefficient of friction and high-temperature resistance.
[0008] As a preferred technical solution of this application, the connecting component includes a fixed bracket and an adjusting bolt. The fixed bracket is welded to the inner wall of the main frame, and a slotted hole is provided at the end of the fixed bracket for connection with the adjusting bolt. The corrugated baffle unit has mounting ears at both ends, with through holes on the mounting ears. The adjusting bolt passes through the through holes and connects to the slotted hole on the fixed bracket. By adjusting the position of the adjusting bolt, the tilt angle of the corrugated baffle unit can be changed, thereby adapting to the flow characteristics of different materials.
[0009] As a preferred technical solution of this application, the driving device includes a motor, a transmission shaft, and a linkage mechanism. The motor is fixed to the outside of the main frame. One end of the transmission shaft is connected to the motor output shaft via a coupling, and the other end passes through the main frame and is hinged to the linkage mechanism. The linkage mechanism includes a first link and a second link. One end of the first link is fixedly connected to the transmission shaft, and the other end is hinged to the second link. The other end of the second link is hinged to the mounting lug of the corrugated baffle unit. By driving the transmission shaft to rotate through the motor, the linkage mechanism is moved, thereby causing the corrugated baffle unit to oscillate back and forth within a certain range, promoting the uniform distribution of materials.
[0010] As a preferred technical solution of this application, the width of the lifting channel is designed according to the size of the material particles, specifically ranging from 10mm to 30mm, to avoid blockage of the material in the channel. The bottom surface of the lifting channel is provided with a guide plate, the inclination angle of which is between 15° and 30°, to guide the material to the drying area of the next stage.
[0011] As a preferred technical solution of this application, the inner wall of the main frame is provided with a heat insulation layer made of aluminum silicate fiber material, which has good heat insulation performance and can effectively reduce heat loss. The top of the main frame is provided with a feed inlet and the bottom is provided with a discharge outlet. Both the feed inlet and the discharge outlet are connected to external pipelines through flanges to facilitate the input and output of materials.
[0012] As a preferred technical solution of this application, the wave-shaped baffle unit is provided with reinforcing ribs at the crests and troughs. The reinforcing ribs are arranged along the length direction of the wave-shaped baffle unit to improve the structural strength of the wave-shaped baffle unit and prevent deformation during long-term use.
[0013] As a preferred technical solution of this application, an observation window is provided on the outer side of the main frame. The observation window is made of high-temperature resistant glass, which facilitates operators to monitor the internal operating status of the equipment in real time. A sealing ring is provided around the observation window to prevent heat loss from the observation window.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] By incorporating corrugated baffle units and their surface grooves, materials can slide along the curved surface of the baffle units and enter the lifting channel during flow, reducing the residence time of materials on the baffle surface and thus lowering the likelihood of material adhesion. The reciprocating oscillation of the corrugated baffle units further enhances the material dispersion effect and improves heat exchange efficiency. Furthermore, the tilt angle of the corrugated baffle units can be adjusted by adjusting bolts to accommodate the flow characteristics of different materials, improving the equipment's versatility. The insulation layer on the inner wall of the main frame effectively reduces heat loss, while the observation window design facilitates daily maintenance and operational monitoring. The overall structure is simple and compact, easy to clean and maintain, solving the problems of complex internal structures and difficult cleaning in existing technologies.

[0023] This utility model provides a corrugated baffle plate type anti-sticking material drying device, the overall structure of which is as follows: Figure 1 As shown, the system includes a main frame 1, a wave baffle assembly 2, and a drive unit 3. The main frame 1 serves as the support structure for the equipment, housing the wave baffle assembly 2 internally and the drive unit 3 externally. The main frame 1 has a feed inlet at the top and a discharge outlet at the bottom, both connected to external pipelines via flanges for easy material input and output. The inner wall of the main frame 1 is equipped with an insulation layer 14 made of aluminum silicate fiber material, providing excellent thermal insulation and effectively reducing heat loss. An observation window 15, made of high-temperature resistant glass, is located on the outer side of the main frame 1, allowing operators to monitor the equipment's internal operating status in real time. The observation window 15 is surrounded by a sealing ring to prevent heat loss.
[0024] The wave deflector assembly 2 is installed on the inner wall of the main frame 1, and its specific structure is as follows: Figure 2As shown, the system includes several corrugated baffle units 4. Each corrugated baffle unit 4 has multiple groove structures 5 on its surface, which are alternately distributed along the crests and troughs of the corrugated baffle unit 4. The corrugated baffle unit 4 is formed by stamping metal sheet, and the curvature radius of its crests and troughs is optimized according to the material's flowability to reduce the possibility of material stagnation. The depth and width of the groove structures 5 are proportional to the wavelength of the corrugated baffle unit 4, specifically between 1:5 and 1:8, to ensure that the material can be effectively guided into the lifting channel 6 during the flow process. A lifting channel 6 is formed between two adjacent corrugated baffle units 4. The width of the lifting channel 6 is designed according to the particle size of the material, specifically between 10mm and 30mm, to avoid material blockage in the channel. A guide plate 13 is provided on the bottom surface of the lifting channel 6, with an inclination angle between 15° and 30°, to guide the material to the next stage drying area. The surface of the corrugated baffle unit 4 is coated with an anti-stick coating made of polytetrafluoroethylene (PTFE), which has a low coefficient of friction and high temperature resistance, further reducing the possibility of material adhesion. Reinforcing ribs are provided at the crests and troughs of the corrugated baffle unit 4, arranged along its length to improve its structural strength and prevent deformation during long-term use.
[0025] The wave-shaped baffle unit 4 is fixed to the inner wall of the main frame 1 by connectors. The specific structure of the connectors is as follows: Figure 3 As shown, the system includes a fixed bracket 7 and an adjusting bolt 8. The fixed bracket 7 is welded to the inner wall of the main frame 1, and a slotted hole is provided at the end of the fixed bracket 7 for connecting with the adjusting bolt 8. The corrugated baffle unit 4 has mounting ears 9 at both ends, with through holes on the mounting ears 9. The adjusting bolt 8 passes through the through holes and connects to the slotted hole on the fixed bracket 7. By adjusting the position of the adjusting bolt 8, the tilt angle of the corrugated baffle unit 4 can be changed, thereby adapting to the flow characteristics of different materials. The adjustment range of the adjusting bolt 8 is determined by the length of the slotted hole. During adjustment, the adjusting bolt 8 needs to be loosened, moved to the desired position, and then retightened to ensure the stability of the corrugated baffle unit 4.
[0026] The drive unit 3 includes a motor 10, a transmission shaft 11, and a linkage mechanism 12, the specific structure of which is as follows: Figure 4As shown. The motor 10 is fixed to the outside of the main frame 1. One end of the transmission shaft 11 is connected to the output shaft of the motor 10 via a coupling, and the other end passes through the main frame 1 and is hinged to the linkage mechanism 12. The linkage mechanism 12 includes a first link and a second link. One end of the first link is fixedly connected to the transmission shaft 11, and the other end is hinged to the second link. The other end of the second link is hinged to the mounting lug 9 of the wave-shaped baffle unit 4. The motor 10 drives the linkage mechanism 12 to move through the transmission shaft 11, thereby causing the wave-shaped baffle unit 4 to oscillate back and forth within a certain range. The design of the linkage mechanism 12 allows the oscillation amplitude and frequency of the wave-shaped baffle unit 4 to be adjusted according to the characteristics of the material. The oscillation amplitude is determined by the rotation angle of the transmission shaft 11, and the oscillation frequency is controlled by the speed of the motor 10.
[0027] The sectional view of the main frame 1 is as follows Figure 5 As shown, the insulation layer 14 evenly covers the inner wall of the main frame 1, with a thickness between 20mm and 50mm, to ensure the heat insulation effect of the equipment. The observation window 15 is located on the outer side of the main frame 1, with dimensions of 300mm × 200mm. A rubber sealing ring with a thickness of 5mm is provided around the observation window 15 to effectively prevent heat loss. The length of the guide plate 13 matches the length of the material lifting channel 6. The installation angle of the guide plate 13 can be adjusted by welding or bolting to ensure that the material can smoothly enter the next stage of the drying area.
[0028] In practical applications, after the material enters the equipment through the feed inlet, it slides along the curved surface of the corrugated baffle unit 4 under the action of the baffle unit 4 and enters the lifting channel 6. The reciprocating oscillation of the corrugated baffle unit 4 ensures that the material is evenly distributed within the lifting channel 6, while the groove structure 5 effectively guides the material flow and reduces the residence time of the material on the baffle surface. After the material undergoes preliminary drying in the lifting channel 6 under the action of hot air, it enters the next stage drying area through the guide plate 13. The presence of the insulation layer 14 reduces heat loss of the equipment and improves thermal energy utilization. The design of the observation window 15 allows operators to monitor the internal operating status of the equipment in real time and promptly detect and handle abnormalities. Cleaning and maintenance of the equipment can be carried out by disassembling the corrugated baffle unit 4 or through the observation window 15, which is simple and efficient.
[0029] This invention achieves uniform material distribution and efficient heat exchange through the above-mentioned structural design, solving the problems of material adhesion, accumulation, and insufficient heat exchange caused by unreasonable baffle surface design when the existing drying equipment processes high humidity or high viscosity materials. At the same time, it improves the shortcomings of complex internal structure and difficult cleaning and maintenance of the equipment.
[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.
[0031] In actual operation, the material to be dried is first conveyed into the main frame 1 through the feed inlet. After entering the equipment, the material slides along the curved surface of the corrugated baffle unit 4 under the action of gravity. The crest and trough design of the corrugated baffle unit 4 is optimized, and its radius of curvature can effectively reduce the possibility of material retention. At the same time, since the surface of the corrugated baffle unit 4 is coated with a polytetrafluoroethylene anti-stick coating, which has a low coefficient of friction and high temperature resistance, it can further reduce the adhesion between the material and the baffle. On this basis, the groove structure 5 on the surface of the corrugated baffle unit 4 is alternately distributed along the crests and troughs, and its depth and width ratio to the wavelength is between 1:5 and 1:8, which effectively guides the material into the lifting channel 6 during the flow process, avoiding the occurrence of material accumulation.
[0032] Meanwhile, the motor 10 in the drive unit 3 drives the linkage mechanism 12 via the transmission shaft 11, thereby driving the wave-shaped baffle unit 4 to reciprocate. The oscillation amplitude of the wave-shaped baffle unit 4 is determined by the rotation angle of the transmission shaft 11, while the oscillation frequency is controlled by the speed of the motor 10. This dynamic motion not only promotes the uniform distribution of materials in the lifting channel 6, but also significantly increases the contact area between hot air and materials, thus achieving efficient heat exchange. In addition, the width of the lifting channel 6 is designed to be between 10mm and 30mm according to the size of the material particles to ensure smooth flow of materials in the channel without blockage. The guide plate 13 on the bottom surface of the lifting channel 6 has an inclination angle of 15° to 30°, further guiding the materials to move to the next stage of the drying area.
[0033] As the material passes through the lifting channel 6, hot air is introduced from inside the main frame 1, making full contact with the material to complete the initial drying. The presence of the insulation layer 14 reduces heat loss during equipment operation, thereby improving thermal energy utilization. Operators can monitor the internal operating status of the equipment in real time through the observation window 15, promptly detect abnormalities, and take corresponding measures. The rubber sealing ring around the observation window 15 is 5mm thick, which effectively prevents heat loss and ensures the insulation effect of the equipment.
[0034] When it is necessary to adapt to the flow characteristics of different materials, the tilt angle of the corrugated baffle unit 4 can be adjusted by adjusting bolt 8. Specifically, by loosening the adjusting bolt 8 and moving it along the slot on the fixed bracket 7 to the desired position, and then tightening it again, the angle of the corrugated baffle unit 4 can be changed. This design significantly improves the versatility of the equipment, making it suitable for drying various materials.
[0035] Finally, the pre-dried material is guided by the guide plate 13 into the next drying area and eventually discharged through the outlet. Throughout the process, the reinforcing rib design of the corrugated baffle unit 4 effectively improves its structural strength and prevents deformation due to long-term use. In addition, the cleaning and maintenance of the equipment can be carried out by disassembling the corrugated baffle unit 4 or by using the observation window 15, which is simple and efficient.
[0036] In summary, this invention, through the unique design and dynamic movement of the wave-shaped baffle unit 4, solves the problems of material adhesion, accumulation, and insufficient heat exchange that easily occur in existing drying equipment when processing high-humidity or high-viscosity materials. At the same time, the equipment has a compact and reasonable structure, is easy to clean and maintain, and significantly improves upon the shortcomings of existing technologies.
[0037] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
