Description
Technical Parameters
In the vast fields of scientific research and industrial production, vacuum drying technology is widely used due to its unique advantages. Especially in laboratory environments, Lab Vacuum Drying Oven have become indispensable equipment for samples with high purity, thermal sensitivity, susceptibility to oxidation, or containing complex components. However, traditional vacuum drying ovens often face problems such as condensed water accumulation, high energy loss, and inconvenient sample extraction during long-term operation. In response to these pain points, this utility model proposes an innovative laboratory vacuum drying oven water removal device, aiming to achieve effective removal of condensed water, reduce energy loss, and improve the processing efficiency of samples after drying through optimized structural design.
Product Structure & Model
Lab Vacuum Drying Oven technology utilizes the principle of reducing the boiling point of volatile substances such as water in a vacuum state to quickly remove moisture from materials at lower temperatures, avoiding adverse reactions such as material denaturation and oxidation that may occur at high temperatures. However, in a vacuum environment, as moisture evaporates, condensed water will accumulate inside the drying oven. If not treated in a timely manner, it will not only affect the drying effect but may also cause damage to the equipment. In addition, frequent opening of doors to remove condensed water can lead to a significant loss of energy and increase operating costs. Therefore, it is particularly important to develop an efficient and energy-saving vacuum drying oven water removal device.

In order to solve the above problems, a new type of laboratory vacuum drying oven water removal device was designed to achieve automatic collection and removal of condensed water, while optimizing the sample placement and removal methods, improving drying efficiency and operational convenience. The device mainly consists of core components such as a drying oven, water storage tank, tray support, and guide groove. These components work together to form an efficient and stable vacuum drying system.
Device structure and working principle
1. Design of drying oven and drying room
The core of this device is the drying oven, which has a carefully designed drying chamber inside. The bottom of the drying chamber is connected to the water reservoir through an inlet pipe, and the bottom is inclined towards the location of the water reservoir. This design cleverly utilizes the effect of gravity, allowing the condensed water generated during the vacuum drying process to flow smoothly into the water storage tank, avoiding the accumulation of condensed water in the drying chamber.
2. Water storage tank and valve system
The water reservoir is located below the drying oven and is used to collect and store the condensed water discharged from the drying chamber. The water storage device is equipped with a condensate inlet valve and a condensate outlet valve. By controlling the opening and closing of these two valves, flexible adjustment of the condensate collection process can be achieved. When it is necessary to discharge condensed water, simply open the outlet valve without opening the drying oven door, effectively reducing energy loss.
3. Design of drying chamber top and guide groove
The top of the drying chamber is designed as an arc-shaped structure with an opening facing the drying chamber, which is conducive to the natural convergence and drainage of condensed water. At the same time, there are multiple guide grooves on the back wall of the drying chamber, which further guide the condensed water gathered at the top to the bottom of the drying chamber, and finally discharge it into the water reservoir through the inlet pipe. The setting of the diversion groove not only improves the efficiency of condensate removal, but also avoids the disorderly flow and dripping of condensate in the drying room.
4. Tray support and sample placement
The tray bracket is located at the top of the drying chamber and is used to support the tray for placing samples. There is a certain distance between the tray bracket and the back wall of the drying chamber, which not only provides space for the flow of condensed water, but also facilitates the placement and removal of samples. The design of the tray fully considers the shape and size of the sample, ensuring that the sample can be uniformly heated and maintain a good fluffy state during the drying process. In addition, the material and structure of the tray bracket have been carefully selected and optimized to ensure its stability and durability.
Product Parameter
Technological innovation points
1. Bottom design of inclined drying chamber
By tilting the bottom of the drying chamber towards the location of the water reservoir, this utility model achieves natural flow and collection of condensed water. This design not only simplifies the process of condensate removal but also reduces energy loss and the need for manual intervention.
2. The synergistic effect of the curved top and the guide groove
The arc-shaped design at the top of the drying chamber and the flow guide groove on the rear wall work together to form an efficient condensate collection and guidance system. This system ensures that condensed water flows quickly and orderly towards the bottom of the drying chamber and ultimately into the water storage tank.
3. Optimization design of tray bracket
The design of the tray bracket fully considers the convenience of placing and removing samples. By reasonably setting the distance between the tray bracket and the back wall of the drying chamber, and optimizing the structure and material of the tray, this utility model improves the fluffiness and removal efficiency of the dried samples.
