Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a drying equipment for drying fluffy materials. Background Technology

[0002] The immense capillary forces in conventional dryers cause structural collapse. Before drying, the material is in an incompletely solid state, its three-dimensional nanoporous network filled with solvent. Conventional dryers use conventional thermal evaporation, which generates extremely strong capillary forces during solvent evaporation. This enormous shrinkage stress directly breaks down the fragile porous network, leading to severe collapse of the nanostructure, a sharp decrease in porosity, and significant shrinkage of the material, thus causing it to lose its unique ultra-high specific surface area and low density properties. Furthermore, conventional dryers are inefficient and time-consuming. Because they use outside-to-inside heat conduction, heat is difficult to transfer evenly and quickly throughout the material. To ensure thorough drying, extremely long drying times are often required. This is not only inefficient and energy-intensive, but prolonged heat exposure may also exacerbate the risk of thermal degradation or oxidation of the material. Moreover, controlling the drying rate is difficult and prone to defects. Therefore, how to provide a controllable and efficient drying device for loose materials is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] The main objective of this invention is to provide a drying device for drying fluffy materials, thereby solving the aforementioned technical problems. The device is equipped with a controllable drying assembly that generates a high-temperature airflow within the working chamber. Furthermore, the drying assembly can control the airflow temperature within the working chamber, and the circulating high-temperature airflow can improve the drying rate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drying device for drying fluffy materials includes a main frame, a working chamber at the top of the main frame, a drying assembly at the top of the inner wall of the working chamber, a plurality of first rollers rotatably connected inside the working chamber, connection holes at both ends of the working chamber, second rollers rotatably connected to the outer wall of the working chamber near the connection holes, and drying doors on both the front and rear sides of the working chamber.

[0005] Furthermore, the drying assembly includes a drive mechanism, a motor, a heating rod mounting frame, heating rods, and a fan. Multiple drive mechanisms, motors, and heating rod mounting frames are detachably connected to the top of the working chamber. The output end of the motor passes through the outer wall of the working chamber and extends into the working chamber to connect with the fan. Heating rod mounting frames are provided on both sides of the motor, and heating rods are provided on the heating rod mounting frames. The motor and heating rods are electrically connected to the drive mechanism.

[0006] Furthermore, the drive mechanism includes an electrical cabinet and a line shielding box, both of which are fixed to the top of the working chamber. The connecting lines on the electrical cabinet are electrically connected to the motor and the heating rod respectively through the line shielding box.

[0007] Furthermore, both ends of the working chamber are provided with exhaust gas discharge mechanisms. Each exhaust gas discharge mechanism includes a ventilation cavity fixed to the outer wall of the working chamber, a ventilation opening at the bottom of the ventilation cavity, an exhaust pipe connected to the top of the ventilation cavity, and a butterfly valve installed on the exhaust pipe.

[0008] Furthermore, a thermocouple is also provided on the heating rod mounting frame, and the thermocouple is electrically connected to the electrical cabinet.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This invention features a controllable drying component that creates a high-temperature airflow environment within the working chamber. Drying the substrate in this environment prevents shrinkage and deformation, resulting in more complete drying. Furthermore, the drying component allows control of the airflow temperature within the working chamber, and the circulating high-temperature airflow improves the drying rate. Thermocouples transmit signals to the electrical cabinet, enabling operators to precisely control the temperature within the working chamber through the interaction of the thermocouples and the cabinet.

[0018] In this embodiment, the drying assembly includes a drive mechanism, a motor 10, a heating rod mounting frame 12, a heating rod 4, and a fan wheel 3. Multiple drive mechanisms, motors 10, and heating rod mounting frames 12 are detachably connected to the top of the working chamber. The output end of the motor 10 penetrates the outer wall of the working chamber and extends into the working chamber to connect with the fan wheel 3. Heating rod mounting frames 12 are provided on both sides of the motor 10, and heating rods 4 are mounted on the heating rod mounting frames 12. Both the motor 10 and the heating rods 4 are electrically connected to the drive mechanism. After the airflow generated by the fan wheel 3 is heated by the heating rods 4, the hot air forms a uniform downward circulation under pressure due to the sealed structure of the working chamber. The heating rods 4 are firmly fixed and positioned by the dedicated heating rod mounting frames 12, ensuring the accuracy, stability, and maintainability of the heating element installation.

[0019] In this embodiment, the drive mechanism includes an electrical cabinet 2 and a wiring shielding box 13. Both the electrical cabinet 2 and the wiring shielding box 13 are fixed to the top of the working chamber. The connecting lines on the electrical cabinet 2 are electrically connected to the motor 10 and the heating rod 4 respectively through the wiring shielding box 13. The wiring shielding box 13 is used to shield and protect the lines, neatly storing and shielding the cables connecting the electrical cabinet 2 to the heating rod 4 and the motor 10, effectively preventing damage to the lines caused by external pulling, high temperature or accidental contact, making equipment maintenance convenient. The electrical cabinet 2 can control the opening and closing of the motor 10 and the heating rod 4.

[0020] In this embodiment, both ends of the working chamber are provided with exhaust gas discharge mechanisms. Each exhaust gas discharge mechanism includes a ventilation cavity fixed to the outer wall of the working chamber. A ventilation port 6 is provided at the bottom of the ventilation cavity, and an exhaust pipe is connected to the top of the ventilation cavity. A butterfly valve 5 is provided on the exhaust pipe. A fan is also provided on the exhaust pipe for extracting exhaust gas.

The butterfly valve 5 can control the exhaust gas discharge rate.

[0021] In this embodiment, a thermocouple 11 is also provided on the heating rod mounting frame 12. The thermocouple 11 is electrically connected to the electrical cabinet 2. The thermocouple 11 can detect the temperature inside the working chamber and transmit the signal to the electrical cabinet 2.

[0022] Working principle: During use, the substrate to be dried is extended sequentially from the second roller 8 and the first roller 7 at one end of the working chamber to the second roller 8 at the other end of the working chamber. Then, the motor 10 and the heating rod 4 are turned on through the electrical cabinet 2. The motor 10 drives the impeller 3 to rotate. When the impeller 3 rotates, it drives the heated air around the heating rod 4 to flow, thereby forming a high-temperature airflow. The temperature of the high-temperature airflow is detected by the thermocouple 11. The high-temperature airflow flows in the working chamber and dries the substrate. During the drying process, the toxic or flammable solvent vapors volatilized from the substrate rise and flow to the exhaust gas discharge mechanism at both ends of the working chamber under the action of the impeller 3, and are discharged through the exhaust gas discharge mechanism.
