Production of Mobile Toilets in Yichang

The mobile toilets produced in Yichang feature a diverse range of brands, high-quality materials, and advanced technology, widely applied in various scenarios.

Brands and Types: Numerous brands in Yichang are engaged in the production of mobile toilets, such as Changjiu Environmental Protection, Yibingsi, and Xinmingyang. They offer a rich variety of types, including mobile toilets and eco-friendly toilets, meeting the needs of different scenarios and users.

Material Selection: A variety of materials are used in the production of mobile toilets, including stainless steel, color-coated steel, and steel structures. Stainless steel is corrosion-resistant and has high strength, ensuring long-term use of the toilets. Color-coated steel is lightweight, easy to install, and has certain thermal insulation properties. Steel structures are sturdy and durable, capable of withstanding significant external forces and providing stable structural support for the toilets.

Production Technology and Working Principles:

• Sewage Discharge System: Designed based on fluid mechanics principles, it is a non-gravity sewage discharge system. When the flush button is pressed, an electric pump or manual piston creates a local low-pressure area in the sealed water tank, and external atmospheric pressure forces water into the toilet bowl, following Bernoulli's principle. Additionally, the pipeline interface is equipped with a one-way check valve to prevent wastewater backflow.
• Layered Storage: After wastewater enters the storage tank, the interior of the tank is divided into upper and lower layers based on density differences. The upper layer is the liquid area, and the lower layer is the solid sediment area. A vent valve with an activated carbon filter layer is installed at the top, allowing gases to slowly escape through capillary action and adsorb odor molecules.
• Evaporative Reduction System: It utilizes phase change principles in thermodynamics for reduction treatment. The exterior of the tank is coated with a light-colored coating to reflect solar radiation, and phase change materials in the interlayer maintain a constant temperature inside the tank within a range where microbial activity is low. More advanced models are equipped with built-in electric heating rods to allow moisture to escape as steam, reducing the volume of solid residues to one-third of the original volume.
• Pipeline Layout: It adopts a gradually narrowing main pipeline, with the pipe diameter gradually decreasing from upstream to downstream, forcing the fluid to maintain laminar flow and preventing secondary suspension of solid particles caused by turbulence. All elbow angles are controlled within 45 degrees, and guide vanes are installed at right-angle bends to reduce energy losses caused by eddies.
• Material Surface Treatment: It employs a molecular-level anti-adhesion mechanism to effectively solve the problem of waste adhering to the inner walls.

Application Scenarios: The mobile toilets produced in Yichang are widely used in various outdoor activities, construction sites, or large gathering venues. For example, at the Daolang concert with tens of thousands of attendees in Yichang, Hubei on August 3rd, additional mobile toilets were set up to serve the fans.
