Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum drying equipment, in particular to a vacuum drying cabinet. Background Art

[0002] A vacuum drying cabinet is a highly efficient, airtight drying device. By creating a vacuum environment and incorporating a built-in heating system, it quickly and evenly dries items placed on specialized trays. Designed to maintain a clean and efficient drying process, it's suitable for dehydrating a wide range of materials and is an essential tool in laboratories and industrial production.

[0003] Traditional vacuum drying technology typically consists of a cabinet and a vacuum chamber, equipped with a heating device and a material placement platform. This traditional method uses heated air to dry the material. However, poor air circulation often results in low heating efficiency and uneven heating of the material. Material at the top of the tray may be completely dry while the material at the bottom remains damp. This not only affects drying speed but can also compromise drying quality, resulting in incomplete or over-drying of the material. Utility Model Content

[0006] Furthermore, the top and bottom of the sliding door are both provided with a first flip seat and are connected by screws, two connecting rods are provided on one side of the first flip seat, a second flip seat is provided on the cabinet body and is connected by screws, and the two ends of the connecting rod are respectively connected to the first flip seat and the second flip seat through a rotating shaft.

[0007] Furthermore, a plurality of buckle locks are provided on both sides of the cabinet body, and the cabinet body and the sliding door are fastened by the buckle locks.

[0008] Furthermore, a universal wheel is provided at the bottom of the cabinet and is connected by screws.

[0009] Furthermore, a plurality of heat dissipation vents are provided on the side of the controller.

[0010] Furthermore, a plurality of handles are provided on the outside of the sliding door and are connected by screws.

[0011] Beneficial effects: The utility model has reasonable design and has the following beneficial effects:

[0012] In this solution, hollow air ducts and oblique air holes are installed within the vacuum chamber, effectively recycling hot air and significantly improving heating efficiency. This design allows hot air to evenly pass through the breathable sealing membrane and the breathable plate, heating and drying the material from the bottom. This effectively solves the problems of low heating efficiency and uneven heating in the existing technology, thereby improving drying speed and quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Combine Figures 1 to 5A vacuum drying cabinet shown in the figure includes a cabinet body 1 and a vacuum cabin 2. A controller 3 is provided on the top of the cabinet body 1, a sliding door 4 is provided on one side of the cabinet body 1, a plurality of partitions 5 are provided in the vacuum cabin 2, a plurality of heating lamps 6 are provided below the partitions 5, and a tray 7 is provided at a position relatively below the heating lamp 6. The tray 7 includes a tray body 71, and a plurality of hollow air ducts 72 are penetrated by the tray body 71 and connected by welding. Oblique air holes 73 are provided on both sides of the hollow air duct 72, and a breathable plate 74 is placed above the hollow air duct 72. A breathable sealing plate membrane 75 is laid on the bottom of the breathable plate 74 and adhered to it. After the hot air in the vacuum cabin 2 enters the hollow air duct 72, it is transferred from the oblique air holes 73 to the bottom of the breathable plate 74, and passes through the breathable sealing plate membrane 75 and the breathable plate 74 to heat and dry the material placed above the breathable plate 74 from the bottom.
