Abstract
Description
Technical Field
[0001] This invention relates to a drying device for porous or loose samples, involving hot air contact across the entire surface. It is used in conjunction with a housing assembly and a blowing assembly of a uniform heat field drying device, enabling uniform drying of porous or loosely structured samples. Specifically, it relates to a drying device that uses a horizontal rotating assembly to drive a placement tray to rotate horizontally, and an angled motion assembly to drive the placement tray to flip back and forth, ensuring that the porous or loosely structured sample rotates continuously while flipping back and forth, guaranteeing that all surfaces and pores of the sample are fully contacted by hot air for uniform drying. Background Technology
[0002] In industrial production, proper drying of samples can effectively remove moisture and other volatile substances, preventing deterioration, decomposition, or clumping due to dampness. It also improves sample stability and quality, facilitating subsequent storage and use. A common drying device is the hot air oven, which generates hot air through heating elements and uses a blowing system to direct the hot air onto the sample surface, causing surface moisture to evaporate and achieving drying. However, existing ovens often use individual blowing or fixed heating blowing methods, directing hot air onto the surface of statically stacked samples. This typically removes moisture from the exposed parts of the sample first, followed by continuous blowing to remove moisture from the interior of the sample stack. This process is time-consuming, involves significant ineffective heating, consumes high energy, and is prone to uneven drying. Furthermore, for temperature-sensitive samples, continuous hot air can cause localized overheating of exposed areas, leading to sample failure or reduced activity.
[0003] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "A Uniform Thermal Field Drying Device." This device utilizes dual motors to drive a tray to rotate in both directions and to flip it repeatedly, achieving three-dimensional tumbling of the sample within the tray. The convection currents in the drying process uniformly dry all surfaces of the rotating and tumbling sample, preventing localized heat concentration. However, this uniform thermal field drying device cannot achieve continuous, large-amplitude tumbling during operation. For porous or loosely structured samples, such as sponge-like materials, gel foams, and fiber-reinforced materials, uneven shrinkage can easily cause the samples to collapse and clump.

Detailed Implementation
[0011] This invention discloses a drying device for full-surface hot air contact of porous or loose samples, comprising a support assembly, a horizontal rotation assembly, and an angled motion assembly. The horizontal rotation component is positioned on the support component, and the angled motion component is positioned on the support component. The angled motion component and the horizontal rotation component are rotatably connected. The support component includes a horizontally supporting base (33) and a vertically supporting bracket, which provide stable support for the horizontal rotation component and the angled motion component. The angled motion component uses a worm gear and gear transmission to convert the reciprocating rotation driving force of the motor into the back-and-forth turning force of the placement tray (11), ensuring that the porous or loosely structured sample is continuously turned over during the drying process, avoiding clumping and uneven drying. The horizontal rotation component uses a worm gear to drive the placement tray (11) to rotate continuously horizontally, which, together with the angled motion component, makes the porous or loosely structured sample rotate continuously while turning over, ensuring that each surface and pore of the sample is fully in contact with the hot air, achieving uniform drying and effectively preventing clumping and collapse.

Preferably, a bearing is placed between the second worm (40) and the third U-shaped support plate (41). The third gear (37) meshes with the second worm (40). The hollow connecting column (44) is rotatably placed on the square bracket (30), with the top and bottom ends of the hollow connecting column (44) extending out of the square bracket (30) respectively. Preferably, the connection between the hollow connecting column (44) and the square bracket (30) is provided with a bearing. The third gear (37) is fitted onto the bottom end of the hollow connecting column (44) and is fixedly connected to the hollow connecting column (44). The top of the hollow connecting column (44) is fixedly connected to the first U-shaped support plate (28). The first connecting strip (27) passes through the T-shaped connector (25) and is fixedly connected to the T-shaped connector (25). Preferably, the first connecting strip (27) is fixedly connected to the horizontal column of the T-shaped connector (25), and the vertical rod of the T-shaped connector (25) is a telescopic rod. The first connecting strip (27) is rotatably connected to the first U-shaped support plate (28). Preferably, the connection between the first connecting strip (27) and the first U-shaped support plate (28) is provided with a bearing. The storage tray (11) is fixedly connected to the T-shaped connector (25). The included angle motion assembly consists of a first support block (34), a fourth motor (35), a first worm gear (31), a second U-shaped support plate (32), a second gear (36), a solid connecting column (43), a fourth gear (42), a first gear (26), and a first connecting strip (27). The first support block (34) and the base (33) are fixedly connected. The fourth motor (35) is placed on the first support block (34). The second U-shaped support plate (32) and another L-shaped bracket (29) are fixedly connected. The first worm gear (31) passes through both sides of the second U-shaped support plate (32). One end of the first worm gear (31) is fixedly connected to the shaft of the fourth motor (35), and the other end is rotatably connected to the second U-shaped support plate (32). A support bearing is placed between the first worm gear (31) and the second U-shaped support plate (32). The second gear (36) meshes with the first worm (31). The second gear (36) is fitted onto the bottom of the solid connecting post (43) and is fixedly connected to the solid connecting post (43). The solid connecting post (43) penetrates the interior of the hollow connecting post (44), and the top of the solid connecting post (43) is fixedly connected to the fourth gear (42). Preferably, a bearing is placed between the solid connecting column (43) and the hollow connecting column (44). The fourth gear (42) meshes with the first gear (26). The first gear (26) is fixedly mounted on the first connecting strip (27); In use, turn on the fourth motor (35). The shaft of the fourth motor (35) rotates in both directions, driving the first worm (31) to rotate. The rotation of the first worm (31) in both directions drives the second gear (36) to rotate in both directions. The rotation of the second gear (36) in both directions drives the fourth gear (42) to rotate in both directions. The rotation of the fourth gear (42) in both directions drives the first gear (26) to rotate in both directions. At the same time as the first gear (26) rotates in both directions, it drives the first connecting strip (27) to rotate in both directions. At the same time as the first connecting strip (27) rotates in both directions, it drives the T-shaped connector (25) to flip in both directions. As the component (25) flips over, it drives the tray (11) to flip over as well, thereby turning over the porous or loose sample in the tray (11). The fifth motor (39) is turned on, and the fifth motor (39) drives the second worm (40) to rotate. The second worm (40) drives the third gear (37) to rotate. The third gear (37) drives the hollow connecting column (44) to rotate. The hollow connecting column (44) drives the first U-shaped support plate (28) to rotate, thereby driving the tray (11) to rotate horizontally, so that the various surfaces and pores of the porous or loose sample that have been turned over are evenly and uniformly dried by the wind.
[0012] The solid connecting column (43) is designed to work with the second gear (36) and the fourth gear (42) to transmit the power of the fourth motor (35) to the first gear (26). This design can drive the T-shaped connector (25) to rotate the tray (11) in both directions, thereby turning the porous or loose sample in the tray (11) and ensuring that the sample continues to rotate during the drying process, avoiding clumping and uneven drying. The design of the hollow connecting column (44) and the third gear (37) to transmit the power of the fifth motor (39) to the first U-shaped support plate (28) enables the horizontal rotation of the tray, so that the surfaces and pores of the porous or loose sample that have been turned over are evenly and uniformly dried by the wind, avoiding clumping or collapse. The solid connecting column (43) and the hollow connecting column (44) are coupled with gear transmission, which enables the fourth motor (35) and the fifth motor (39) to be located below the drying hot airflow, and the hot airflow with moisture flows upward, avoiding damage to the electronic components of the power source during the continuous drying process and improving the reliability of the device. The second worm (40) and the first worm (31) are designed to reduce speed by cooperating with the second gear (36) and the third gear (37). This design can prevent the sample from being damaged by excessively fast flipping and rotation speed. At the same time, the smooth movement can prevent rotation or overturning caused by inertia, improve the reliability and stability of operation, and have a high load capacity. The vertical rod of the T-shaped connector (25) is designed as a telescopic rod, which can control the length of the vertical rod of the T-shaped connector (25) according to different sample characteristics, thereby controlling the flipping radius of the tray (11), and flipping the porous or loose samples with different characteristics in the tray (11) to a suitable flipping amplitude, thus improving versatility. The goal is to achieve the effect of rotating the sample tray horizontally via the horizontal rotating component and flipping the sample tray back and forth via the angled motion component, so that porous or loosely structured samples can rotate continuously while being flipped back and forth, ensuring that all surfaces and pores of the sample are fully in contact with the hot air for uniform drying.
[0013] It should be noted that the drying equipment for full-surface hot air contact of porous or loose samples needs to be used in conjunction with the outer shell assembly and blowing assembly of the following uniform heat field drying equipment.

The blowing component is equipped with symmetrical airflow drive motors and fans to form a drying convection to uniformly dry each surface of the sample that is flipped back and forth and rotated, avoiding local heat concentration. During the process of the multi-motor collaborative mechanism driving the placement tray (11) to rotate back and forth and flip back and forth, the drying airflow generated by the blowing component is disturbed, so that the airflow is evenly diffused.

This not only improves the ease of operation but also reduces energy loss and moisture ingress. A bearing is placed between the second motor shaft (18) and the T-shaped support plate (16). The bearing provides stable support and guidance for the shaft, ensuring that the shaft can maintain high precision during rotation. The tray (11) adopts a hollowed-out mesh design, which can increase the contact area between each surface of the sample and the hot air, thereby improving the drying efficiency; at the same time, the hollowed-out structure can also promote air circulation, avoid local temperature being too high or too low, and make the drying more uniform. The system can achieve multi-directional dynamic drying by using dual motors to drive the connecting rod and U-shaped bracket to rotate, thereby rotating the sample tray to flip the sample. Dual fans are used for drying, which can achieve efficient, multi-directional drying of samples with low energy consumption.
