[0026] In the prior art, the dehumidifying dryer usually adopts a fixed hopper design, and the hopper is integrated with the overall structure of the dryer. After the material is dried, it is difficult to transfer the material in the drying hopper. In the process of transferring the material, it is difficult to see the accumulation of the material in the drying hopper due to the integrated design of the equipment, and the phenomenon of blockage and residue occurs. Not only does this reduce the material yield, but it also increases the difficulty of cleaning and maintaining the drying hopper. In addition, due to the integrated design of the equipment, the drying hopper is prone to displacement or loosening due to vibration or external impact during the drying or transferring process, which reduces the service life of the equipment and causes mechanical damage.

[0027] In view of this, the utility model embodiment provides a kind of material drying equipment based on dehumidifying dryer, refer to Figure 1 , including drying hopper and vacuum hopper 2, vacuum hopper 2 is communicated with suction fan 3 and material bucket 4, the discharge port of vacuum hopper 2 is communicated with the top cover 1 of drying hopper, the bottom of drying hopper is communicated with drying fan 5 to be discharged into the material bucket of drying hopper after heating air and dry material, top cover 1 is also communicated with drying fan 5 to circulate back to drying fan 5 with wet hot air, it also includes frame, frame includes the first connecting column 6 perpendicular to ground, second connecting column 7, third connecting column 8 and fourth connecting column 9, the top end between the first connecting column 6 and the top end of second connecting column 7 is welded with the fifth connecting column 10, the top end between the third connecting column 8 and the top end of fourth connecting column 9 is welded with the sixth connecting column 11, the outer wall of the material bucket of drying hopper is welded with oppositely arranged first connecting plate 12 and second connecting plate 13, the pulley 14 of first connecting plate 12 and second connecting plate 13 is installed on the surface towards ground, the pulley 14 of first connecting plate 12 is slidingly connected on the fifth connecting column 10, the pulley 14 of second connecting plate 13 is slidingly connected on the sixth connecting column 11.

[0028] The hot air from the hopper of the drying hopper is cooled and blown into the honeycomb wheel in the drying fan 5, the moisture in the hot air is adsorbed by the wheel, and then the heated air in the drying fan 5 acts on the wheel at the same time, the rotation of the wheel makes the moisture in the air continuously adsorbed and discharged, when the temperature continues to be heated to the required drying temperature of the material, the drying hopper is blown into the drying hopper through the bottom of the drying hopper, forming a closed cycle, so as to dry the material. In some embodiments, the outlet of the heated air is located at the bottom of the conical hopper of the drying hopper, so as to generate a flow path of the material bucket rising from the conical hopper. In some embodiments, the outlet of the heated air can be close to the bottom of the hopper in the drying hopper, so as to maximize the flow path of the heated air in the drying hopper, so as to achieve better drying effect.

[0029] The frame includes a first connecting column 6, a second connecting column 7, a third connecting column 8 and a fourth connecting column 9 arranged vertically, and a fifth connecting column 10 and a sixth connecting column 11 welded at the top of each connecting column to form a transverse support, so as to realize uniform distribution of force and reduce the risk of insufficient overall rigidity. The pulley 14 is installed on the first connecting plate 12 and the second connecting plate 13, so that the hopper is subjected to the action of guiding force during sliding, thereby smoothly moving along the predetermined track. By taking advantage of the small rolling friction, the displacement error caused by vibration or equipment impact is reduced, and at the same time, the material is not easy to collide or tilt during transfer.

[0030] In some embodiments, a seventh connecting column 15 is welded between the top of the first connecting column 6 and the top of the third connecting column 8. The seventh connecting column 15 is arranged between the first connecting column 6 and the third connecting column 8, and its position can further provide transverse support, so that the frame becomes a whole, and each connecting point can be effectively supported when subjected to external force impact, thereby reducing local deformation. The addition of the seventh connecting column 15 helps to realize the balanced distribution of internal force of the equipment, and ensures that each structural member can work within the designed bearing range during material transfer and equipment vibration, preventing structural fatigue caused by excessive local stress.

[0031] In some embodiments, an eighth connecting column parallel to the fifth connecting column 10 is welded between the first connecting column 6 and the second connecting column 7, a ninth connecting column parallel to the sixth connecting column 11 is welded between the third connecting column 8 and the fourth connecting column 9, and a tenth connecting column 16 parallel to the seventh connecting column 15 is welded between the first connecting column 6 and the third connecting column 8. By designing the eighth connecting column, the ninth connecting column and the tenth connecting column 16, further transverse support is provided, which provides auxiliary support on the basis of the fifth connecting column 10, the sixth connecting column 11 and the seventh connecting column 15, so that the frame has a multi-layer transverse support structure, improving the stability of the frame.

[0032] In some embodiments, the eleventh connecting column 17 is welded between the seventh connecting column 15 and the tenth connecting column 16, and a lock catch 18 is fixed on the outer wall of the bucket. When the bucket is located in the frame, the lock catch 18 is sleeved on the eleventh connecting column 17. The lock catch 18 cooperates with the eleventh connecting column 17, so that when the bucket is located in the frame, the lock catch 18 is sleeved into the eleventh connecting column 17, mechanical locking is achieved, and static fixation is formed. By using physical clamping, it is ensured that the bucket can remain stable during equipment operation even if it is impacted by the outside world, thereby preventing material leakage or equipment damage caused by displacement.

[0033] In some embodiments, rubber pads are attached to the faces of the fifth connecting column 10, the sixth connecting column 11, the seventh connecting column 15, the eighth connecting column, the ninth connecting column, and the tenth connecting column 16 near the bucket. The rubber material has good elasticity and damping effect, and can form a flexible contact surface between the bucket and the frame to reduce the transmission of impact force caused by vibration. Due to the high friction coefficient of the rubber pad, accidental sliding or displacement of the bucket during sliding can be effectively prevented, and stable operation of the transmission system is ensured.

[0034] In some embodiments, a platform 19 parallel to the bottom surface is fixed in the frame, and the bucket includes a detachable connection of a cylindrical barrel and a conical barrel. The conical barrel is detachably connected with a discharge pipe, the discharge pipe is fixed on the platform 19, and a baffle is rotatably connected between the discharge pipe and the conical barrel, and the baffle is used to block the bucket when the baffle is rotated between the discharge pipe and the conical barrel.

[0035] The detachable connection of the cylindrical barrel and the conical barrel enables quick disassembly and replacement after the material drying is completed, thereby facilitating cleaning and maintenance. The discharge pipe is fixed on the platform 19 and the baffle is installed by a rotating connection device between the discharge pipe and the conical barrel. The baffle can block or open the discharge passage when rotating, and the sealing and release during the material discharge process are realized by using the mechanical rotation principle, which ensures the stability of material transfer and improves the discharge efficiency. The cylindrical barrel and the conical barrel are detachably connected, and the conical barrel and the discharge pipe are detachably connected. The detachable connection can be used to complete the combination during material processing and separation after material processing using the existing latching structure. The cylindrical barrel and the conical barrel can be disassembled for cleaning, which is convenient for processing different materials and preventing material pollution.

[0036] In some embodiments, the baffle is a metal baffle, and the baffle uses a metal material with high temperature resistance, which will not pollute the material during drying.

[0037] In some embodiments, an observation window is provided on the bucket. The observation window is made of transparent or semi-transparent high-temperature-resistant material, which can be used to visually check the internal material while maintaining the airtightness and dry environment of the device. By providing the observation window, non-contact monitoring is achieved, which reduces energy loss and pollution risk caused by frequent opening of the device, and provides a basis for process control.

[0038] In some embodiments, referring to Figure 2 , the top cover 1 is circular, and the top cover 1 includes two semicircular cover plates, one of which is rotatably connected to the other by a hinge 101, the discharge port of the vacuum hopper 2 is communicated with one of the semicircular cover plates, the drying fan 5 is communicated with the semicircular cover plate communicated with the discharge port of the vacuum hopper 2, and the semicircular cover plate not communicated with the discharge port of the vacuum hopper 2 is fixed with a handle 102.

[0039] The top cover 1 is composed of two semicircular cover plates, one of which is rotatably connected to the other by a hinge 101, realizing the function of local opening. This design uses the principle of hinge 101 rotation, which can maintain the overall sealing and facilitate local opening for material inspection. By connecting the discharge port of the vacuum hopper 2 with one of the semicircular cover plates and connecting the drying fan 5 with the other semicircular cover plate, the two functions are clearly separated, which facilitates process control and avoids functional interference caused by mixed structure. The cover plate not communicated with the discharge port is fixed with a handle 102, which can be easily opened by the operator for observation, while ensuring that the sealing state can be quickly restored when closed.

[0040] In some embodiments, the top cover 1 is a metal top cover 1, which uses metal material with high temperature resistance and does not contaminate the material during drying.

[0041] In summary, the material drying equipment based on the dehumidification dryer provided by the utility model realizes efficient transfer of the material bucket through the combination of the pulley 14 and the connecting column and the smooth sliding of the material bucket along the predetermined track in the frame. The structural design effectively reduces the vibration and impact risk of the equipment during the transfer process, simplifies the subsequent disassembly and cleaning process, and has high operation efficiency and reliability. The multiple connecting columns and the cross-welding thereof form a stable support frame, and the frame can uniformly disperse stress when transmitting external impact force and reduce local stress concentration. The rubber pad pasted on the contact surface of the material bucket close to the frame further plays a shockproof and anti-skid role, reduces the equipment wear caused by mechanical vibration, and guarantees the firmness and safety of the overall structure during operation. The cooperation and fixing design of the lock buckle 18 and the eleventh connecting column 17 ensure that the material bucket can be automatically locked when located in the frame, preventing accidental displacement during material processing. The establishment of the fixing measure not only improves the stability of the equipment during operation but also reduces the safety hazards caused by the sliding of the material bucket during maintenance. The top cover 1 is designed as a circular structure and is composed of two semicircular cover plates, one of which is rotationally connected to the other through a hinge 101. This design enables the local opening of the top cover through the handle 102 fixed on the cover plate without the connected discharge port under the premise of closed drying, thereby directly observing the material state in the hopper and facilitating the timely adjustment of process parameters during the drying process, guaranteeing the production continuity and safety. In addition, the use of the metal top cover 1 guarantees the wear resistance and structural rigidity, meeting the requirements of long-term continuous operation. The combination of the discharge pipe fixing platform 19 and the conical bucket and the round bucket ensures the stability of the discharge pipe during the transfer of the material bucket and prevents displacement, thereby ensuring smooth discharge of the material during efficient transfer.
