Working principle of escalator cleaning machine
Automatic escalator handle cleaning machines are a special type of cleaning equipment.Escalators are ubiquitous means of transportation in public places such as shopping malls, subway stations, and airports. However, few people pay attention to the hygiene issues of escalator handrails. Every day, a large number of people come into contact with handrails, and various bacteria, viruses, and dirt accumulate on the handrails. For example, research has found that there are food residues, E. coli, mucus, feces, and even blood on the handrails of escalators. In this situation, the escalator handrail cleaning machine plays a crucial role in maintaining public health.
Working Process of Escalator Handrail Cleaning Machines
1. Pre cleaning inspection
Before the formal cleaning process, some advanced cleaning machines may first inspect the surface of the armrest. This step mainly involves determining the degree of dirt and possible types of pollutants on the armrest. For example, through sensors, it can detect the organic content or the presence of specific harmful substances on the surface of the armrest. This pre cleaning detection helps the cleaning machine to more accurately adjust the cleaning intensity and the amount of cleaning agent used in subsequent steps.
2. Cleaning Agent Application
The first step in the actual cleaning process is usually the use of cleaning agents. Different cleaning machines use different methods of applying cleaning agents. Some cleaning machines are equipped with spray devices. These spray are precisely designed to spray cleaner evenly on the surface of the handrail. The formula of the cleaning agent can decompose various types of dirt. For example, for body oils, sticky substances, mucus, and saliva left by previous users on handrails, cleaning agents contain surfactants and solvents. These ingredients can emulsify oil and dissolve viscous substances, making it easier to remove from the surface of the handrail.
3. Mechanical Cleaning
After the cleaning agent has been in effect for a period of time, mechanical cleaning begins to take effect. Most escalator handrail cleaning machines use specially designed cleaning pads or brushes. These cleaning pads are usually made of ultra-fine fiber materials. Microfibers have a large surface area and strong adsorption capacity, which can effectively capture dirt particles. The pad is connected to the molded pad bracket. During the cleaning process, as the escalator handrail moves, the cleaning pad will clean the handrail one by one. Some machines, such as the Maestro system, can be connected to accessible mobile handrails. The armrest system has a patented rotating arm that can be easily placed on any armrest. These mechanical cleaning methods ensure that every part of the handrail is thoroughly cleaned without interrupting the normal operation of the escalator.
4. Sanitizing
Sanitizing is an essential step in the cleaning process of escalator handrails. After the dirt is removed, an EPA - registered disinfectant/antimicrobial is applied. This sanitizing solution can kill a wide range of germs, viruses, and bacteria. For example, it can inactivate common cold viruses, flu viruses, and even the COVID - 19 virus that may be present on the handrail. The application of the sanitizing solution can be achieved through a spraying or soaking method in the cleaning machine. Some cleaning machines have a separate sanitizing compartment, where the handrail passes through after mechanical cleaning and is thoroughly sanitized.
5. Drying and Polishing (Optional)
In some high - end escalator handrail cleaning machines, there may be additional steps of drying and polishing. After sanitizing, if the handrail is wet, a drying device is used to remove the moisture on the handrail surface. This can prevent the growth of mold and mildew in a humid environment. Some machines use hot air blowers to dry the handrail quickly. Additionally, a polishing step may be included. A conditioner is applied to the handrail during the polishing process. This conditioner helps maintain the form and substance of the handrail rubber material. It also restores a clean - looking sheen and shine to the handrail, making it not only clean and hygienic but also aesthetically pleasing.
