Product Description

Product Description

QDPP Integrated Sewage Treatment Equipment

I. Product Definition

The QDPP Integrated Sewage Treatment Equipment derives its name from its innovative raw materials, primarily composed of a cutting-edge high-molecular material. Crafted through advanced mold-forming techniques, this equipment emerges as a seamless, robust tank. The talented Zhong Qiao Enlightenment R&D team, leveraging Western technology, has surmounted design challenges to create this exceptional tank. Tailored for the rural Chinese market, this equipment aligns with local sewage conditions and discharge standards. This has led to the development of various models, including Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and the unique Hollow Tank, embodying superior design and functionality.

II. Raw Materials

The chosen raw material is high-modulus polypropylene, celebrated for its excellence in buried drainage and sewage treatment applications. With an impressive elastic modulus of ≥1500 MPa, this material significantly surpasses HDPE, which has only 800 MPa. The elastic modulus is paramount in determining the ring stiffness of the product, where a higher modulus ensures greater stiffness and durability.
Polypropylene stands out as a non-toxic, odorless, and tasteless polymer. Its high crystallinity and low density (0.90-0.91 g/cm³) make it one of the lightest plastics available. Its stability in water is remarkable, with an absorption rate of just 0.01%. The material's molecular weight ranges from 80,000 to 150,000, offering excellent molding capabilities, along with a sleek, glossy finish.

Boasting exceptional chemical stability, polypropylene resists a wide array of chemical reagents. While concentrated sulfuric and nitric acids may erode it, it withstands exposure to many other substances. The material's chemical stability is enhanced with increased crystallinity, making it a prime candidate for manufacturing a wide range of chemical equipment and components that require robust corrosion resistance.
Polypropylene, noted for being non-toxic and odorless, also boasts superior strength and stiffness. Compared to low-density polyethylene, it offers enhanced hardness and heat resistance, performing well around 100°C. Additionally, it provides excellent dielectric properties and maintains high-frequency insulation, unaffected by humidity.
Its resilience to common acids, bases, and organic solvents makes polypropylene an ideal choice for food utensils, offering both safety and durability.
PPH is a high molecular weight, low melt flow rate homopolypropylene. Through β-modification, it achieves a refined crystalline structure, delivering outstanding chemical resistance, high-temperature endurance, excellent creep resistance, and remarkable impact resistance even at low temperatures.



III. Characteristics



1. Safety
 

The tank is manufactured using a spiral extrusion winding-one-time forming technology. The tank is formed directly from granular raw materials through molds, achieving a seamless, one-piece structure.

2. Durability

The raw materials include UV-resistant and anti-aging additives, addressing the issue of short outdoor service life for plastic equipment and significantly extending its lifespan.

3. Economic Efficiency

The tank can have a thickness of over 80 mm, with a tapered cross-section. The thickness can be increased in areas with greater stress at the lower part of the tank, optimizing the use of materials where needed.

4. Corrosion Resistance


It exhibits excellent resistance to various acids and bases and can store most organic and inorganic acids, bases, salts, and some organic solvents (see the corrosion data sheet for details).

5. Flexible and Convenient Installation
Lightweight, easy to install and maintain, non-toxic, non-scaling, and non-contaminating. It is user-friendly, customizable according to customer needs, and allows for flexible overall installation.
6. Wide Application Range

This equipment is perfectly engineered for diverse industries, including wastewater treatment,
air pollution control, and the burgeoning field of lithium battery new energy. It proves indispensable in chemical, metallurgy, and electroplating sectors,
and extends its utility to chemical fiber, dyeing, environmental protection, petroleum, electronics, pharmaceuticals, food, oils, and light industry. It also excels in acid production, acid washing, and
manufacturing battery materials.

IV. Structural Appearance

Main Equipment Color: The primary hue is a sophisticated light gray, with the flexibility to customize colors based on specific client requests.
Equipment Structure: Available in both solid wall and hollow structures, catering to varied operational needs.



V. Production Process

The QDPP Integrated Sewage Treatment Equipment utilizes a pioneering one-time forming and multiple winding production process. The wall thickness varies from 10-80 mm, achieving optimal durability. The multiple winding technique includes winding the base layer, followed by a cooling and crystallization phase that effectively releases internal stress. Subsequent layers are meticulously wound after reheating the surface of the base layer. Depending on the tank's design and specifications, the number of winding layers and thickness can be customized.

VI. Welding Process

The external welding process of our QDPP Integrated Sewage Treatment Equipment is a marvel of precision engineering. Utilizing advanced imported automatic extrusion welding machines, we create robust, enduring welds in the tank's most stress-prone areas, all in a single operation. By using pristine PPH pellets that are identical in composition to the tank material, we achieve a thermal fusion at the weld seams that forms a rock-solid union with both the tank bottom and body, ensuring exceptional strength and durability.



Distinct Characteristics:

1. Our product boasts a high level of mechanization and automation, which guarantees unwavering product quality and performance consistency.
2. The design of the weld seams is meticulously crafted based on the unique stress characteristics of the product, thus maximizing structural integrity and reliability.
3. The product demonstrates outstanding integrity, with welds seamlessly integrating into the tank, which significantly enhances the tank's resistance to corrosion and prevents leaks efficiently.
4. The aesthetic appeal of our products is unmatched, with seams that are not only functionally smooth but also visually attractive, boasting minimal flash.
5. To further extend our equipment's service life, UV absorbers are judiciously added to the PPH pellets, effectively safeguarding against aging and environmental wear.


Sophisticated Internal Welding

Our internal welding process employs state-of-the-art automatic long-arm extrusion welding technology, a pivotal phase in our fabrication process. By thermally fusing new PPH pellets, identical to the tank material, at internal weld seams, we ensure they become one with the tank bottom and body. This method mirrors the external welding principle but utilizes specialized equipment, ensuring unmatched internal cohesion and durability.


Key Characteristics:
1. The high degree of mechanization and automation in our production process ensures consistent product quality and operational reliability.
2. Weld seams are meticulously engineered based on stress characteristics to optimize their robustness and integrity.
3. Our product features exceptional integrity, with welds blending seamlessly into the tank, providing superior resistance to corrosion and a leak-proof guarantee.
4. The seams are crafted to minimize flash, ensuring they are not only functionally smooth but also visually pleasing.
5. To combat aging and prolong the life of the equipment, UV absorbers are incorporated into the PPH pellets, providing lasting protection.
