Hami Foam-Sealing Mobile Toilet

The Hami foam-sealing mobile toilet is a mobile sanitation facility that achieves water conservation, odor control, and strong adaptability through foam technology. Its core principles, advantages, application scenarios, and maintenance points are as follows:

1. Working Principle
The foam-sealing technology optimizes functionality through three stages:

• Foam Generation: The foaming device mixes a specific ratio of liquid and air to form a cluster of microbubbles that cover the excretion channel, creating a flexible barrier.
• Odor Blocking: The foam barrier physically isolates the reverse diffusion of gases within the pipeline, suppressing odors at the source. Experiments show that it can reduce liquid consumption by approximately 80%.
• Self-Cleaning Function: When new foam is generated, it pushes the old foam carrying impurities along the pipeline, achieving automatic cleaning and reducing manual intervention.

2. Core Advantages

• Outstanding Water Conservation: The water consumption per flush is only 0.1-0.3 liters, with a water-saving rate exceeding 90%. Field tests at the Beijing Olympic venues showed a water-saving rate of 98%. In Baotou City, after implementing a circulating water system, the comprehensive water-saving rate exceeded 99%, with each toilet stall saving approximately 50 tons of water annually.
• Significant Odor Control: The foam layer physically isolates feces from air contact, and some products add fragrances to give the foam a pleasant scent. Field tests show that the ammonia concentration in the toilet cubicle drops below 0.1 ppm, meeting indoor air quality standards.
• Strong Adaptability: It adapts well to different states of feces and is less prone to clogging. It operates within a temperature range of -30°C to 60°C. Winter tests in Inner Mongolia show that the built-in electric heater ensures normal foaming at -35°C. The aluminum alloy frame combined with insulated wall panels enhances cold resistance, and it is also earthquake-resistant up to magnitude 7, making it suitable for extreme environments like the Qinghai-Tibet Railway.

3. Application Scenarios

• Outdoor Temporary Events: Such as music festivals and sports events that require rapid deployment and high sanitation standards.
• Tourist Attractions: Especially suitable for remote scenic spots or nature reserves lacking water supply and drainage networks.
• Construction Sites: Provides workers with a hygienic and odor-free toilet environment.
• Vehicle-Mounted Mobile Toilets: Can be installed on vehicles or trailers for flexible movement and use.

4. Maintenance Points

• Daily Maintenance: Regularly replenish the foaming solution, check the air pump's operating status, and the core components (such as the foaming solution storage tank and mixing generator) can operate thousands of times before needing material replenishment.
• Precautions: Choose foaming solutions that comply with technical specifications; regularly calibrate the control system to ensure the appropriate liquid-to-air mixing ratio; take anti-freezing measures in low-temperature environments (such as using built-in electric heaters).
• Smart Upgrades: The new generation of systems incorporates smart monitoring functions that can automatically indicate the remaining amount of consumables, record usage frequency, and monitor operating status, enhancing reliability and convenience.
