Product Structure and Scale Formation in Tunnel-Type Washing Units

1. Please ask Deep Seek to input the following question and see the answer:
I’d like to understand the product structure of tunnel-type washing units (tunnel continuous washing systems or laundry dragons), particularly: How are garments transferred from the first chamber to the second chamber? I’d appreciate a detailed explanation of the process. In the main washing chamber, detergents are used and the water is heated. The wastewater washed off the garments is highly contaminated, leading to scale buildup on the spiral plates during transport. Approximately how thick would the scale be after one year of operation? What disinfection measures should be applied to the spiral plates?
II. After deep and thorough consideration, here is the response:
Product structure of tunnel-type washing units
The tunnel-type washing unit is a continuous washing system primarily used for large-scale linen washing in venues such as hotels and hospitals. Its core structure comprises multiple washing chambers, each responsible for a different stage of the washing process, including pre-washing, main washing, rinsing, and neutralization. Laundry items are moved between these chambers via a conveyor system, thereby completing the entire washing cycle.
Clothing transfer process
Conveyor System: Garments are moved between warehouses via spiral plates or conveyor belts. Spiral plates are typically made of stainless steel, which can withstand high temperatures and chemical corrosion while efficiently conveying garments.
Transmission mechanism:
Spiral plate: The spiral plate rotates, propelling the laundry from one compartment into the next. The plate’s design ensures even distribution of the laundry, preventing it from accumulating in one spot.
Water level control: The water level in each compartment is precisely controlled to ensure smooth garment transport while preventing backflow.
Transition Zone: A transition zone is provided between storage compartments to ensure that garments fully move from one compartment into the next, preventing any stagnation.
Scale problem
Scale Formation: The main wash compartment uses detergent and heating, and the wastewater contains a large amount of impurities, making it prone to scale buildup on the spiral plates. This scale is primarily composed of minerals such as calcium carbonate and magnesium salts.
Scale thickness: After one year of use, the scale thickness typically ranges from a few millimeters to one centimeter, with the exact thickness depending on water quality, frequency of detergent use, and the condition of equipment maintenance.
Disinfection measures for spiral plates
Chemical disinfection: Regularly use acidic cleaning agents (such as citric acid or acetic acid) to remove scale and perform disinfection.
High-temperature disinfection: Regularly use the device’s built-in high-temperature function to kill bacteria and microorganisms.
Mechanical cleaning: Regularly disassemble the spiral plates and perform mechanical cleaning to ensure that no residual dirt remains.
UV Disinfection: Some equipment is equipped with UV disinfection devices to further ensure hygiene.
Summary
The tunnel-type washing unit uses spiral plates to transfer clothes between chambers. Wastewater from the main washing chamber can easily cause scaling on the spiral plates, and after one year, the thickness of the scale can range from several millimeters to one centimeter. To maintain hygiene, regular chemical disinfection, high-temperature sterilization, and mechanical cleaning are necessary.
3. Based on Deep Seep’s conclusions, do you feel that there’s something wrong with WS/T508?
With such thick scale buildup, how many bacteria must be present? Has the drafting group for WS/T508 conducted any research to determine exactly how thick the scale is? Have they considered whether scale removal is necessary? And have they thought about implementing specific, effective measures?
