Description

Technical Field

[0001] This utility model relates to the technical field of raw material processing and drying equipment, and in particular to a raw material drying device. Background Technology

[0002] In the field of raw material processing, drying is a key process to ensure the quality of raw material forming and the stability of subsequent processing. It is widely used in industries such as ceramics, food, and building materials. In the traditional raw material drying process, the raw material needs to be transferred to an independent drying equipment by manual labor or simple machinery to complete the dehydration treatment. The drying equipment usually uses static placement or single-layer conveying to carry the raw material and relies on hot air circulation to achieve moisture evaporation. Optimizing the utilization rate of drying space and heat transfer efficiency has become an important direction for improving production efficiency.

[0003] Existing raw material drying devices rely on manual labor or independent equipment to complete the transfer and drying processes, making it difficult to achieve fully automated operation from conveying to drying and unloading. This increases the time required for process transitions and the cost of manual intervention. In terms of space utilization, traditional devices often adopt planar conveying or single-layer drying structures, resulting in limited drying capacity. Furthermore, the hot air distribution is easily affected by structural limitations, leading to uneven drying efficiency. To address these issues, we propose a raw material drying device.

The bearing plate portion at the inclined surface is exposed.

[0009] Optionally, heat insulation baffles are provided in the gaps on the upper, lower, left, and right sides of the drying main frame. The heat insulation baffles make the drying main frame form a semi-enclosed structure, with openings only at the feeding position of the corresponding pneumatic material handling module and the corresponding discharging position. A heat transfer component is fastened to the heat insulation baffle directly above the drying main frame. The heat transfer component includes a heat transfer pipe, a heat conversion joint, and a dustproof net. The heat conversion joint is fastened to the top of the heat insulation baffle. The heat transfer pipe is connected to the upper end of the heat conversion joint. The dustproof net is located at the lower end of the heat conversion joint. A heat conduction module is fastened to the inner side of the triangularly distributed transmission gear and between the heat insulation baffles on the left and right sides by bolts.

[0010] Optionally, the heat conduction module includes a first dustproof net assembly, a second dustproof net assembly, a first conduction fan, and a second conduction fan.

[0018] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0019] Example 1, refer to Figure 1-4In this embodiment, to address the problem that existing raw material drying devices rely on manual labor or independent equipment to complete the transfer and drying of raw materials, making it difficult to achieve fully automated operation from conveying to drying and unloading, thus increasing process connection time and manual intervention costs; and in terms of space utilization, traditional devices often adopt planar conveying or single-layer drying structures, resulting in limited drying capacity, and the hot air distribution is easily restricted by the structure, leading to unevenness and affecting drying efficiency, this utility model discloses a raw material drying device. The system includes a drying main frame 1, inside which are three triangularly arranged transmission gears 12. A transmission chain 121 is axially arranged between the transmission gears 12. Drive motors 13 are axially mounted on the outer sides of the transmission gears 12 on both sides. Several support modules 2 are fastened at intervals along the length of the transmission chain 121. Each support module 2 includes a first fastening block 21, a second fastening block 22, and a support plate 23. The first fastening block 21 is fastened to the transmission chain 121, the second fastening block 22 is axially connected to the first fastening block 21, and the support plate 23 is fastened between two opposing second fastening blocks 22. The support plate 23 has several ventilation holes 231, and is kept horizontal through the axial connection structure between the first fastening block 21 and the second fastening block 22. The drying main frame 1 is internally connected via... Three triangularly distributed transmission gears 12 and a surrounding transmission chain 121 constitute the core transmission mechanism. Two drive motors 13 on both sides provide power to the transmission chain 121, causing it to circulate along the triangular trajectory. The carrier modules 2, which are spaced apart on the transmission chain 121, are fixed to the chain 121 by a first fastening block 21. The second fastening block 22 axially connects the carrier plate 23 to the first fastening block 21. This connection structure ensures that the carrier plate 23 remains horizontal throughout the entire process of the chain 121 moving along the triangular trajectory, preventing the blank from tilting and slipping. The ventilation holes 231 on the surface of the carrier plate 23 provide a channel for hot air circulation, allowing the upper and lower surfaces of the blank to fully contact the hot airflow, improving the drying uniformity. The triangularly distributed transmission structure can arrange more carrier modules 2 in a limited space, increasing the blank capacity per unit space and improving the drying efficiency.

[0020] The main drying frame 1 is symmetrically arranged with three main support frames at its front. A transmission limiting rail 31 is fastened to each of the three main support frames. A pneumatic material-collecting mold 4 is movably installed within the transmission limiting rail 31. A drive motor 32 is axially mounted at one end of the transmission limiting rail 31. The drive motor 32 is connected to the pneumatic material-collecting mold 4 to drive it to move horizontally reciprocally along the transmission limiting rail 31. The pneumatic material-collecting mold 4 includes a cylinder 41 and a material-collecting part 42. Several pneumatic suction nozzles 43 are arranged directly below the material-collecting part 42. The drying main frame 1 is located at its front. The main support frame 3 provides the installation base for the transmission limit rail 31. The pneumatic material picking module 4 in the transmission limit rail 31 can move horizontally back and forth along the track under the drive of the secondary motor 32 to realize the lateral adjustment of the picking position. The cylinder 41 of the pneumatic material picking module 4 drives the picking part 42 to lift and lower. In conjunction with the pneumatic suction nozzle 43 below the picking part 42, the blank is picked up and released by the negative pressure adsorption principle. This structure realizes the automatic transfer of the blank between the conveying module 5 and the carrier plate 23 through the horizontal movement + vertical lifting and lowering motion.

[0021] A conveyor module 5 is installed between the three main support frames. The conveyor module 5 is arranged perpendicular to the three main support frames and is lower in height than the three main support frames. A conveyor belt 51 is axially mounted on the conveyor module 5. The conveyor module 5 is arranged parallel to the pneumatic material handling module 4. The working position of the material handling part 42 of the pneumatic material handling module 4 corresponds to the inclined surface of the triangularly distributed transmission chain 121 inside the drying main frame 1. The bearing plate 23 at the inclined surface is partially exposed. The conveyor module 5 between the three main support frames continuously transports the blank to be dried to the material handling station through the conveyor belt 51. It is lower than the main support frames. The height design of the support frame 3 and its layout parallel to the pneumatic material handling module 4 provide ample operating space for the material handling unit 42. The working position of the material handling unit 42 of the pneumatic material handling module 4 corresponds to the inclined area of ​​the triangular transmission chain 121. The bearing plate 23 in this area is partially exposed due to the triangular trajectory characteristics, avoiding interference with the frame structure. After the material handling unit 42 picks up the blank from the conveyor belt 51, it is lifted and moved horizontally to the top of the exposed bearing plate 23, and then the loading is completed by lowering and releasing. The whole process is coordinated with the operating rhythm of the transmission chain 121.

[0022] Heat insulation baffles 1a are provided in the gaps on the top, bottom, left, and right sides of the drying main frame 1. The heat insulation baffles 1a make the drying main frame 1 a semi-enclosed structure, with openings only at the feeding position and the corresponding discharge position of the pneumatic feeding mold 4. A heat transfer component 6 is fastened to the heat insulation baffle 1a directly above the drying main frame 1. The heat transfer component 6 includes a heat transfer pipe 61, a heat conversion joint 62, and a dustproof net 63. The heat conversion joint 62 is fastened to the top of the heat insulation baffle 1a. The heat transfer pipe 61 is connected to the upper end of the heat conversion joint 62. The dustproof net 63 is located at the lower end of the heat conversion joint 62. The transmission gears 12 are arranged in a triangular pattern. The heat insulation baffles 1a on the left and right sides are connected to each other. The heat conduction module 7 is installed by bolts. The upper, lower, left and right sides of the drying main frame 1 are equipped with heat insulation baffles 1a, forming a semi-closed structure that retains only the inlet and outlet. This can effectively reduce the diffusion of internal heat to the outside, maintain the temperature stability of the drying area, and reduce energy consumption. The heat transfer component 6 on the heat insulation baffle 1a above introduces the heat source through the heat transfer pipe 61, and after being distributed by the heat conversion joint 62, it is sent into the drying area. The dust screen 63 can filter impurities in the air to avoid contaminating the raw material. The heat conduction module 7 inside the triangular transmission gear 12 is used to conduct the heat accumulated in the upper part to the lower part, solving the problem of uneven drying caused by the temperature difference between the upper and lower parts in traditional devices.

[0023] The heat transfer module 7 includes a first dustproof net 63 assembly, a second dustproof net 63 assembly, a first heat transfer fan 73, and a second heat transfer fan 74. A first mounting groove 7a and a second mounting groove 7b are respectively provided on the front and rear inclined surfaces of the heat transfer module 7. The first dustproof net 63 assembly is slidably installed in the first mounting groove 7a. An integrally formed first operating handle 711 is provided on the left side of the first dustproof net 63 assembly. The second dustproof net 63 assembly is slidably installed in the second mounting groove 7b. An integrally formed second operating handle 721 is provided on the right side of the second dustproof net 63 assembly. The first dustproof net 63 assembly and the second dustproof net 63 assembly are correspondingly spaced. Each position of the heat baffle 1a is provided with a clearance groove 1a1. The first dustproof net 63 component and the second dustproof net 63 component of the heat conduction module 7 are slidably installed through the first mounting slide 7a and the second mounting slide 7b, respectively. The clearance groove 1a1 at the corresponding position of the heat insulation baffle 1a can avoid conflict with the frame structure. The dustproof net 63 component can filter dust and impurities in the hot air flowing through the module, preventing dust from adhering to the surface of the blank or inside the equipment and affecting the drying quality. The first operating handle 711 and the second operating handle 721 make it easy to pull the dustproof net 63 component out of the slide, so as to achieve quick cleaning or replacement, ensuring the filtration effect while simplifying the maintenance process.

[0024] The heat conduction module 7 has an integrally formed mounting partition 7c. A first conduction fan 73 and a second conduction fan 74 are symmetrically arranged above the mounting partition 7c. The first conduction fan 73 and the second conduction fan 74 are radially distributed, and both are axially connected to a main drive motor 75 on their outer sides. The mounting partition 7c inside the heat conduction module 7 provides a symmetrical mounting base for the first conduction fan 73 and the second conduction fan 74. The two fans are radially distributed and driven by the main drive motor 75 on their outer sides. The air venting and guiding grooves opened on the mounting partition 7c correspond to the air outlets of the fans, which can guide the airflow output by the fans to flow along a preset path and avoid airflow turbulence. This structure, through the symmetrical layout of the two fans and the directional guidance of the air venting and guiding grooves, forms a stable airflow circulation power, ensuring that heat is transferred within the module.

[0025] An airflow guide baffle 76 is located directly below the heat conduction module 7. The airflow guide baffle 76 is inclined forward on one side and backward on the other, with the central axis of the mounting baffle 7c as the boundary. The first conduction fan 73 draws in hot air from above and directs it through the forward-inclined airflow guide baffle 76 to the front half of the drying main frame 1. The second conduction fan 74 draws in hot air from above and directs it through the backward-inclined airflow guide baffle 76 to the rear half of the drying main frame 1. The airflow guide baffle 76 directly below the heat conduction module 7 is inclined forward on one side, with the central axis of the mounting baffle 7c as the boundary. The asymmetrical design, with one side tilted backward, matches the airflow output direction of the first conductive fan 73 and the second conductive fan 74, respectively. After the first conductive fan 73 draws in the hot air from the top, it is guided by the forward-tilted guide partition to directionally transport the hot airflow to the front half of the drying main frame 1. The second conductive fan 74 guides the hot airflow to the rear half of the drying main frame 1 through the backward-tilted guide partition. This partitioned guiding structure allows the hot airflow to evenly cover all the bearing plates 23 on the triangular transmission track, avoiding insufficient heat in local areas and ensuring that the blanks in different positions can achieve a consistent drying effect.

[0026] The specific working principle is as follows: After the drive motor 13 starts, it drives the triangularly distributed transmission gears 12 on both sides to rotate synchronously through shaft transmission. This causes the transmission chain 121, which surrounds the three gears, to move in a uniform cycle along the triangular trajectory. In the bearing modules 2 installed at intervals on the transmission chain 121, the first fastening block 21 is rigidly connected to the chain 121, and the second fastening block 22 is movably connected to the first fastening block 21 through an axial hinge structure. This ensures that the bearing plate 23 maintains a horizontal posture throughout the process of the chain 121 rising, falling, and turning along the triangular trajectory, thus stably bearing the blank material. The blank material to be dried is then conveyed... The conveyor belt 51 of module 5 continuously transports materials to the material handling station. After the position sensor is triggered, the conveyor belt 51 stops, and the drive motor 32 drives the pneumatic material handling module 4 to move precisely above the blank along the transmission limit rail 31 via a screw drive. The piston rod of the cylinder 41 extends, causing the material handling part 42 to descend. After the pneumatic suction nozzle 43 contacts the surface of the blank, a negative pressure air source is connected to generate suction force. After grabbing the blank, the cylinder 41 retracts and lifts, and the material handling module moves to the inclined surface of the triangular chain 121. At this time, the bearing plate 23 at this position is exposed in the frame opening due to the operation of the chain 121, and the material handling part 42 descends to the preset height. The rear nozzle cuts off the air supply and releases the blank material, completing the feeding process. The heat transfer pipe 61 of the heat transfer component 6 is connected to an external heat source. Hot air is diverted through the heat conversion joint 62 and passes through the dustproof net 63 into the drying main frame 1. The heat insulation baffles 1a on the upper, lower, left, and right sides form a semi-enclosed space to reduce heat loss. The main drive motor 75 of the heat conduction module 7 drives the first conduction fan 73 and the second conduction fan 74 to operate synchronously. The hot air in the upper part enters the first conduction fan 73 and the second conduction fan 74 after being filtered by the dustproof net 63 component. It is then directed out through the air venting guide groove on the mounting baffle 7c and then through the airflow guide baffle 7. 6. The left side tilts forward to guide the airflow of the first conductive fan 73 to the front half of the frame area, and the right side tilts backward to guide the airflow of the second conductive fan 74 to the rear half of the frame area, so that the hot air evenly covers all the bearing plates 23. The hot air penetrates the blank through the vent holes 231 on the surface of the bearing plate 23, and takes away the moisture to achieve drying. When the bearing plate 23 moves to the discharge position with the chain 121, the pneumatic material picking mold 4 grabs the dried blank according to the same logic and transfers it to the next process. The first dustproof net 63 assembly and the second dustproof net 63 assembly can be taken out from the slide by pulling the handle and cleaned regularly to filter impurities.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
