Description

Technical Field

[0001] This utility model relates to the field of vector wind tower technology, and in particular to a vector wind tower for drying precision-cast shell molds. Background Technology

[0002] In the precision casting industry, the drying quality of the investment casting shell mold, also known as the investment casting shell mold, directly determines the forming accuracy, surface quality, and mechanical properties of the subsequent castings. The investment casting shell mold is typically made by coating the surface of the investment mold with multiple layers of refractory materials such as silica sol and mullite powder. It requires multiple drying and curing processes before dewaxing and firing. During the drying process, it is crucial to ensure uniform evaporation of moisture inside and outside the shell mold to prevent cracking and deformation due to uneven drying rates.

[0003] However, during the drying process of the transition layer and back layer of the precision casting shell mold, when conventional fans are used for drying, uneven airflow can easily lead to uneven evaporation of moisture inside and outside the shell mold, resulting in an imbalance in the drying rate and causing the shell mold to crack and deform. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology mentioned above, and to propose a vector wind tower for drying precision-cast shell molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vector wind tower for drying precision-cast shell molds includes a base, a support platform fixedly connected above the base, columns symmetrically arranged above the support platform, a support plate fixedly connected above the columns, a connecting plate fixedly connected above the support plate, the connecting plate being fixedly connected to a first connecting cylinder, a second connecting cylinder fixedly connected above the first connecting cylinder, a drying mechanism being arranged inside the second connecting cylinder, a frame fixedly connected inside the first connecting cylinder, an air guide block being arranged above the frame, a slotted hollow cylinder rotatably connected below the first connecting cylinder, a mounting frame fixedly connected inside the slotted hollow cylinder, a disc being arranged above the mounting frame, a bearing being mounted above the disc, a guide fan being fixedly connected through the central shaft of the bearing and the disc, the slotted hollow cylinder being rotatably connected to the support platform, and air outlet slots being arranged on both sides of the slotted hollow cylinder.

[0006] The above technical solution further includes: The drying mechanism includes a connecting frame disposed inside the second connecting cylinder, a motor is fixedly connected to the central axis of the connecting frame, and a fan blade is fixedly connected to the output end of the motor.

[0007] The base is equipped with multiple sets of casters, each of which has a foot-operated braking and locking function.

[0008] Multiple casters with foot-operated braking and locking functions are located under the base, which can quickly fix the position of the device and prevent displacement due to the rotation of the slotted hollow cylinder and the impact of airflow, ensuring that the airflow accurately covers the shell mold transition layer and the back layer.

[0009] The support platform is equipped with a motor, and the output end of the motor is fixedly connected to a slotted hollow cylinder.

[0010] The motor inside the support platform directly drives the slotted hollow cylinder to rotate, reducing power loss. Combined with the air outlet slot, it achieves dynamic airflow coverage and accelerates the synchronous evaporation of moisture inside and outside the shell mold.

[0011] The edge of the connecting frame is provided with multiple connecting feet for connecting to the inside of the second connecting cylinder.

[0012] The connecting bracket has multiple connecting feet that securely connect to the second connecting cylinder, ensuring stable airflow output during motor operation and preventing uneven air distribution caused by loose components.

[0013] The mounting bracket is provided with multiple sets of connecting feet at its edge for connecting to the inner wall of the slotted hollow cylinder.

[0014] The mounting bracket is fixed to the inner wall of the slotted hollow cylinder by multiple sets of connecting feet, which enhances the rigidity of the cylinder structure, prevents air outlet deviation caused by deformation during rotation, and improves drying consistency.

[0015] The bottom edge of the first connecting cylinder is provided with a track for rotation.

[0016] The track at the bottom of the first connecting cylinder provides stable support for the slotted hollow cylinder, reducing rotational resistance and swaying, ensuring smooth operation in the rotating and drying mode, and reducing the risk of shell mold cracking.

[0017] This utility model has the following beneficial effects: In this invention, the airflow generated by the motor-driven fan blades is first guided to the guide fan by the guide block. The guide fan, through its fixed connection with the central shaft of the bearing, can evenly disperse the airflow into the slotted hollow cylinder. At the same time, the slotted hollow cylinder rotates under the drive of the motor inside the support platform and discharges the airflow through the air outlet slots on both sides, achieving a rotating and uniform air distribution. This uniform airflow dispersion and dynamic coverage of the air outlet direction allow the airflow to fully cover the inner and outer surfaces of the shell mold, as well as the transition layer and back layer area, avoiding local over-drying or under-drying. It ensures that the moisture inside and outside the shell mold evaporates synchronously, reducing cracking and deformation problems caused by unbalanced drying rates from the root.

[0018] In this invention, on the one hand, the universal wheels at the bottom of the device have a braking function, which can stably fix the device in the drying area and prevent the air source from shifting due to device displacement during the drying process, thus ensuring that the airflow always acts precisely on the shell mold. On the other hand, when the slotted hollow cylinder rotates, the symmetrically arranged columns above the support platform form a stable support for the first connecting cylinder through the support plate above the connecting plate, thereby ensuring that the motor inside the second connecting cylinder above the first connecting cylinder runs stably and continuously outputs uniform airflow.

[0024] In one embodiment, for the base 1, multiple sets of casters 2 are provided below the base 1, and each caster 2 has a foot-operated braking and locking function.

[0025] In this embodiment, multiple sets of universal wheels 2 with foot-operated braking and locking functions are located below the base 1, which can quickly fix the position of the device, prevent displacement of the slotted hollow cylinder 8 due to rotation and airflow impact, and ensure that the airflow accurately covers the shell mold transition layer and the back layer.

[0026] In one embodiment, the support platform 3 is equipped with a motor inside, and the output end of the motor is fixedly connected to a slotted hollow cylinder 8.

[0027] In this embodiment, the motor inside the support platform 3 directly drives the slotted hollow cylinder 8 to rotate, reducing power loss. This, combined with the air outlet slot 7, enables dynamic airflow coverage and accelerates the synchronous evaporation of moisture inside and outside the shell mold.

[0028] In one embodiment, the connecting frame 11 is provided with a plurality of connecting feet on its edge for connecting to the inside of the second connecting cylinder 10.

[0029] In this embodiment, multiple connecting feet of the connecting frame 11 are securely connected to the second connecting cylinder 10 to ensure stable airflow output during motor 12 operation and avoid uneven air distribution caused by loose components.

[0030] In one embodiment, the mounting bracket 19 is provided with multiple sets of connecting feet at its edge for connecting to the inner wall of the slotted hollow cylinder 8.

[0031] In this embodiment, the mounting bracket 19 is fixed to the inner wall of the slotted hollow cylinder 8 by multiple sets of connecting feet, which enhances the rigidity of the cylinder structure, prevents air outlet deviation caused by deformation during rotation, and improves drying consistency.

[0032] In one embodiment, for the first connecting cylinder 9, a track for 8 to rotate is provided at the bottom edge of the first connecting cylinder 9.

[0034] The working principle of the vector wind tower for drying precision casting shell molds in this utility model is as follows: First, the entire device is moved to the area where the precision casting shell mold needs to be dried via the universal wheels 2 at the bottom of the base 1. Then, the motor 12 is turned on, and the output end of the motor 12 drives the fan blades 13 to rotate. The rotation of the fan blades 13 generates airflow, which flows along the air guide block 17 to the guide fan 16. The guide fan 16 is fixedly connected to the central axis of the bearing 15. Therefore, when the airflow blows the guide fan 16, the guide fan 16 will evenly disperse the airflow into the interior of the slotted hollow cylinder 8. Then, the motor inside the support platform 3 is controlled to rotate, and the output end of the motor inside the support platform 3 drives the slotted hollow cylinder 8 to rotate. The slotted hollow cylinder 8 will then discharge the airflow through the air outlet slots 7 on both sides. The slotted hollow cylinder 8 will dry the precision casting shell mold while rotating, thereby achieving uniform drying of the precision casting shell mold by the airflow. In addition, the caster wheel 2 has a braking effect, and when the slotted hollow cylinder 8 rotates, the columns 4 symmetrically arranged above the support platform 3 can use the support plate 6 above the connecting plate 5 to support the first connecting cylinder 9, thereby ensuring that the motor 12 inside the second connecting cylinder 10 above the first connecting cylinder 9 can stably output airflow.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
