Description

Technical Field

[0001] This specification relates to the field of drying cabinet technology, and more particularly to a rapid low-temperature vacuum drying cabinet. Background Technology

[0002] Vacuum drying, also known as analytical drying, is a process in which materials are placed under vacuum negative pressure conditions, which lowers the boiling point of water. Water boils at 100°C under one atmosphere of pressure, but under vacuum negative pressure conditions, the boiling point of water can be lowered to 80°C, 60°C, and 40°C, at which point evaporation begins.

[0003] The existing technology includes Chinese utility model patent application number 202420279669, titled "A Vacuum Drying Device for Medical Use," which describes "low-pressure steam being introduced into the heating tube as the heating medium, placing the items to be dried on the partition, closing the upper chamber door, and using a vacuum pump to achieve the corresponding vacuum level. The heating tube heats the items to the specified temperature in the circulating flow of the heating medium, and the moisture begins to evaporate and is gradually removed as the vacuum is drawn. A filter layer is provided in the silicone tubing, which can dry and filter the moisture, reducing the impact on the vacuum pump." However, the device described therein only has one drying chamber, and its volume is only one-third of the total volume of the device. In actual use, this may lead to a significant amount of waiting time when another batch of instruments needs to be dried during the drying process, resulting in low drying efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a rapid low-temperature vacuum drying cabinet to solve the problem of improving the drying efficiency of drying cabinets in the prior art.

[0005] To achieve the above objectives, this utility model provides a rapid low-temperature vacuum drying cabinet, including a first drying cabinet and a second drying cabinet fixedly connected below the first drying cabinet;

[0006] The first and second drying cabinets are identical and are used to increase the drying space.

[0007] The control box is fixedly connected to the bottom of the second drying cabinet. A vacuum pump and a dehumidifier are fixedly installed inside the cabinet. The first and second drying cabinets are connected to the vacuum pump via hoses. The two drying cabinets do not interfere with each other when performing vacuuming. The first and second drying cabinets are connected to the dehumidifier via pipes. The extracted water is stored in a water storage box.

[0008] Preferably, a heating tube is fixedly connected to the back of the inside of the first drying cabinet, and an air extraction hole is opened on the side to extract the internal air to achieve a vacuum state.

[0009] The dehumidifying hole is fixedly connected with a dehumidifier through a pipeline, and is used for extracting water vapor in the drying cabinet.

[0010] Preferably, the front of the first drying cabinet is fixedly connected with a cabinet door through a rotating shaft, and a visible window is arranged on the cabinet door, which is used for observing the state of the internal utensils.

[0011] The outer part of the cabinet door is fixedly connected with a handle through a bolt, and the inner surface is fixedly connected with a door lock.

[0012] Preferably, the side of the first drying cabinet is fixedly connected with a mounting plate through a bolt, and the mounting plate is fixedly connected with a control unit inside.

[0013] Preferably, the water storage box is placed on the supporting plate.

[0014] Preferably, the left and right surfaces of the first drying cabinet are provided with grooves, and the edges of the tray are clamped in the grooves.

[0015] The tray is provided with through holes for water leakage.

[0016] As can be seen from the above, the quick low-temperature vacuum drying cabinet provided by the present application comprises two vacuum drying cabinets arranged above and below each other, which improves the overall space of the drying cabinet, so that when one drying cabinet is working, another drying cabinet can be used to dry another batch of utensils, thereby indirectly improving the drying efficiency.
