Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulator technology, specifically a connection structure for a rising film evaporator. Background Technology
[0002] The feed liquid is preheated to its boiling point and added from the bottom of the heating chamber. It undergoes intense vaporization within the heating tubes, causing the generated vapor to carry the feed liquid upwards in a film-like manner along the tube walls. This liquid film continues to evaporate as it rises. The solution only needs to pass through the heating tubes once to reach the required concentration. This type of evaporator is suitable for dilute solutions with low concentration requirements and for heat-sensitive materials.
[0003] Existing patent CN221412259U discloses a connection structure for a rising film evaporator. This utility model includes a support, a first evaporator, a second evaporator, a sliding groove located on the inner left side of the support, the first evaporator positioned in the middle of the inner side of the support, the second evaporator movably mounted on the right side of the outer wall of the first evaporator and movably connected to the middle of the inner side of the support, and a clamping assembly located on the inner left side of the support. This utility model uses the clamping assembly on the left side of the support to relatively stabilize the pipe connected to the outside of the first evaporator, preventing it from detaching. It also partially abuts the connecting toggle blocks after connection, reducing the possibility of loosening and slippage due to vibration, thus making the connection more stable and reducing potential losses due to unstable connection.
[0004] However, while the existing patent CN221412259U stabilizes the pipe connected to the first evaporator through the clamping assembly on the left side of the bracket, making it less likely to fall off, it can also partially offset the position of the connecting toggle block after connection, reducing the possibility of the connecting toggle block loosening and slipping due to vibration, making the connection more stable and reducing the possible losses caused by unstable connection, if the connection between the pipe and the evaporator is not reinforced, it may lead to heat dissipation, thereby affecting the working efficiency of the device.
