Production of Single Mobile Toilets in Dingxi
The production of single mobile toilets in Dingxi involves multiple key aspects such as structural modular design, material selection, and functional system integration, requiring a combination of standardized processes and customized requirements.
Structural Modular Design
The foundation of mobile toilets is modular construction, utilizing standardized-sized wall, roof, and base frame units that are assembled into a whole through locking mechanisms and waterproof connection techniques. This design supports repeated disassembly and reassembly, facilitating easy transportation and rapid on-site deployment. For example, wall units can integrate pipeline channels to enable concealed routing of water supply and sewage pipes, preventing exposed pipelines from affecting aesthetics and safety.
Material Selection and Lightweight Design
The box materials need to balance lightweight properties with structural strength. Common choices include fiberglass or metal alloy cladding, with internal insulation layers (such as polyurethane foam). Fiberglass is corrosion-resistant and easy to clean, while metal alloys are more durable and suitable for high-frequency usage scenarios. Pipeline channels embedded within the wall sandwich layers can conceal water supply and sewage pipes, while modular design allows for the inclusion of maintenance access ports for easy future upkeep.
Sewage System and Energy Supply
The sewage system operates in two modes: one connects to temporary sewage storage tanks, suitable for sites without fixed drainage facilities; the other interfaces with existing pre-treatment septic tanks on-site, enabling quick switching via pipeline connectors without the need for civil engineering modifications. For energy supply, solar panels on the roof can power lighting and ventilation equipment, with some models equipped with low-voltage direct current drainage valves to reduce energy consumption. Water supply relies on built-in storage tanks, replenished by pumps from external water sources; models for cold regions include anti-freeze layers at the base of the box and heating tapes in the pipes to prevent freezing.
Treatment System and Environmental Design
The treatment system operates independently of traditional drainage networks, employing solid-liquid separation devices to direct waste into fermentation tanks for volume reduction through microbial degradation; the liquid portion undergoes multi-layer filtration for reuse in toilet flushing or green irrigation, or further purification for discharge. The system is typically integrated at the base of the box, with maintenance accessible through side panels. Ventilation design utilizes negative pressure air exchange principles, with intake and exhaust vents creating directional airflow to prevent odor retention and ensure fresh internal air.
Customization and Applicability
Mobile toilets support customized requirements. For example, Henan Shucong Environmental Protection Technology Co., Ltd. offers waterless ecological toilets made of metal carved panels, suitable for temperatures ranging from -20°C to 50°C, with a voltage of 220V, available for sale nationwide; Gansu Guting Metal Products Co., Ltd. provides a variety of models to meet aesthetic and functional needs across different scenarios.
