How to solve the problem of poor sealing of towel dryers

To solve the problem of poor sealing of towel dryers, you can refer to the following methods:

Check the seals: Aging or damage of seals is a common cause of air leakage in dryers. Regularly check the seals of doors, feed ports, discharge ports, flues, drums, fans and other parts. If the seals are found to be aged or damaged, they should be replaced in time to ensure the sealing performance.

Repair the flue: Air leakage in the flue will affect the performance of the dryer. It is necessary to regularly check whether the flue has air leakage. If there is a problem, the flue should be repaired or replaced in time.

Smooth the drum surface: If the drum surface is worn or deformed, it is easy to cause air leakage. Regularly check whether the surface of the drum is flat. If there is wear or deformation, the drum needs to be replaced in time.

Repair the fan: Fan failure may also cause air leakage. Regularly check whether the fan has air leakage. If the problem is found, repair or replace the fan in time.

Adjust the air volume: Excessive air volume may cause air leakage. The air volume can be adjusted appropriately to reduce the occurrence of air leakage.

Strengthen equipment maintenance: The dryer is a high-intensity operation equipment and requires regular maintenance and care, such as cleaning the residue and dust inside the equipment, which can effectively reduce the occurrence of air leakage.

Ensure the installation quality: For newly installed or repaired dryers, ensure that all components are installed correctly, especially the sealing parts are installed tightly. During the installation process, strictly follow the installation requirements of the equipment to ensure that the seals are accurately positioned and reliably fastened.

Improve the sealing structure: such as using better quality sealing materials, or improving the existing sealing structure. For example, for axial contact seals, a movable sleeve can be added to reduce the gap and enhance the sealing performance. The specific method can be referred to as follows: use 12mm thick ordinary steel plate to make a 600mm head cylinder, weld a 16mm thick and 90mm long heat-resistant steel head guard ring on its head, use 12mm thick heat-resistant steel plate to make a sealing retaining ring with an outer diameter of 2700mm and weld it to the appropriate position of the processed head cylinder; use 12mm thick heat-resistant steel plate to make a sealing outer ring with an inner diameter of 2800mm and weld it to the sealing flange ring made of ordinary steel plate; use 16mm thick heat-resistant steel plate to make a set of split (8 pieces) retaining rings according to the original size; prepare 3 pressure blocks and 1mm thick spring steel sheets, and the spring sheets can borrow the sealing spring sheets of the 3.2×52m rotary kiln head; calibrate the head cylinder and the dryer cylinder, weld them, and install the split retaining ring on the head cylinder with bolts.

Different types of dryers may have differences, and the specific solution may need to be adjusted according to the actual situation. If the problem is serious or cannot be solved by yourself, it is recommended to contact a professional repairman for inspection and maintenance. In addition, in daily use, correct operation of the towel dryer and regular inspection and maintenance will also help maintain its good sealing performance.
