Description

Technical Field

[0001] This utility model relates to the field of copper phthalocyanine processing technology, specifically to a low-temperature drying device for infrared absorbing materials. Background Technology

[0002] Driven by information technology, the demand for near-infrared absorbing materials in the field of optoelectronic equipment and sensor manufacturing is constantly increasing. Copper phthalocyanine has become a research hotspot due to its excellent optoelectronic properties. However, when drying copper phthalocyanine, traditional hot air drying relies on high-temperature airflow, which can easily damage the molecular structure of copper phthalocyanine and affect its optoelectronic properties. Natural drying, although gentle, is time-consuming and environmental factors are difficult to control, which can easily introduce impurities and reduce the purity of the material.

[0003] Copper phthalocyanine has a high absorption rate in the near-infrared band, and heating it in an infrared dryer is very effective. However, in the design of commonly available infrared dryers, the infrared lamps are usually placed on the side wall of the chamber, while the drying material is spread in multiple layers on a tray inside the chamber. This results in a difference in drying effect between the material on the sides and the material in the middle of the tray, leading to inconsistent quality of the finished product and high energy consumption. Therefore, a low-temperature drying device for infrared absorbing materials is provided to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-temperature drying device for infrared absorbing materials, which solves the problem that common infrared dryers on the market have different drying effects on the materials on both sides of the tray and the materials in the middle during the drying process, resulting in inconsistent quality of finished products and high energy consumption.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a low-temperature drying device for infrared absorbing materials, comprising a drying chamber and a drying mechanism installed inside the drying chamber, wherein the drying chamber is equipped with an exhaust mechanism, and the drying mechanism includes;

[0006] Movable plates are movably inserted into the interior of the drying oven, and multiple movable plates are placed horizontally and equidistantly so that the top of the movable plates forms a placement station for the dried materials, and the bottom of the movable plates is mirror-polished to form a heat radiation reflective surface.

[0007] An infrared lamp is installed at the bottom of the movable plate to heat the drying material placed on the movable plate below.

[0008] A connector is provided on the outer wall of the drying oven, penetrates the drying oven, and is electrically connected to the infrared lamp tube. The connector also penetrates the side wall of the movable plate to prevent the movable plate from moving backward.

[0009] Preferably, an insulating sleeve is fixedly fitted on the outer surface of the middle part of the connector to keep the connector insulated when it passes through the drying oven and the movable plate.

[0010] Preferably, the drying oven includes a box body and a sealed door that is rotatably disposed on the outer wall of the box body, and the outer wall of the sealed door is fitted with vacuum heat-insulating glass.

[0011] Preferably, an air intake hood is fixedly embedded in the middle of the sealed box door, and a dustproof mesh plate is movably inserted into the interior of the air intake hood.

[0012] Preferably, the exhaust mechanism includes multiple exhaust hoods fixedly installed on the outer wall of the housing, and an exhaust pipe is installed between the multiple exhaust hoods. An axial flow fan is installed on the top of the housing, and one end of the exhaust pipe is connected to the air inlet of the axial flow fan.

[0013] Preferably, a support bracket is fixedly welded to the inner wall of the box, and the movable plate is movably inserted into the support bracket.

[0014] Preferably, a connection socket is fixedly provided on the movable plate, and the connection plug is electrically connected to the infrared lamp tube through the connection socket.

[0015] Preferably, the top surface of the movable plate is integrally formed with reinforcing ribs, the outer wall of the box is fixedly provided with a wire guide box, the connector is movably inserted into the wire guide box, and the outer wall of the wire guide box is rotatably provided with a protective cover to cover or expose the connector.

[0016] Preferably, a control switch is fixedly installed on the outer wall of the enclosure, and a temperature sensor is fixedly embedded in the inner wall of the enclosure, with the control switch and the temperature sensor being controlled and connected.

[0017] This utility model discloses a low-temperature drying device for infrared absorbing materials, which has the following beneficial effects: By setting multiple movable plates inside the chamber and installing infrared lamps at the bottom, a material tray containing materials is placed on top of the multiple movable plates. Infrared irradiation is then carried out by the infrared lamps at the top. Utilizing the high absorption rate of copper phthalocyanine in the near-infrared band, the material is heated, causing the moisture in the copper phthalocyanine to evaporate. At this time, an axial flow fan is activated, allowing external air to enter through the air inlet hood and then exit through the exhaust hood, carrying away the water vapor and thus effectively improving the drying effect. Furthermore, the infrared lamps are positioned directly above the material to ensure uniform drying. Heat radiation reflection from the bottom of the movable plates further enhances the heating effect, resulting in energy saving and consumption reduction. Attached Figure Description
