Center Drive Single-Tube Suction Machine
Products Description
The Center Drive Single-Tube Suction Machine (Suction Dredger) is highly efficient sludge collection and separation equipment specifically designed for the secondary clarifiers of wastewater treatment plants. The equipment comprises core components such as a working bridge, center vertical frame, rotating cage, scraping frame, mud collection cylinder, suction pipe, skimming mechanism, and transmission mechanism. Operationally, the center drive unit rotates the scraping and suction frames slowly inside the pool via the vertical frame. Utilizing the negative pressure generated by the water level difference between the inside and outside of the pool, the suction holes on the single tube use static water pressure to draw activated sludge into the collection cylinder and discharge it. Concurrently, a scraper on the opposite side gathers inert sludge into a central pit, while a surface skimming device collects floating scum, achieving comprehensive and highly efficient mud-water separation.

Core Specific Selling Points
Highly Energy-Efficient (Saves 40-50% Power)
Because it ingeniously utilizes the negative pressure of static water to suck up the mud, the energy consumption for mechanical lifting is drastically reduced. Compared to similar domestic equipment with the same processing capacity, it can save 40% to 50% in electricity consumption (e.g., a 12m diameter pool requires only a 0.25KW motor).
01
Negative Static Pressure Suction Yields High Sludge Concentration
The single-tube suction device does not rely on forceful water pumps. Instead, it utilizes the water level difference (negative pressure and static water pressure) to draw sludge into the cylinder. This steady collection method not only offers a large processing capacity but also ensures the discharged sludge has a very high concentration.
02
Multiple Safety Protection Mechanisms
The equipment features robust electrical and mechanical designs, specifically equipped with torque overload protection and an overload alarm. If it encounters a severe underwater obstruction, the system will automatically protect itself, ensuring safe and reliable 24-hour continuous operation.
03
Three-Dimensional Cleaning with a Small Footprint
It not only processes activated sludge (via suction) and inert sludge (via scraping) at the bottom simultaneously but also comes with a surface skimming device and scum hopper to collect liquid surface scum. The overall structure is highly compact, boasting a massive processing capacity while maintaining a small footprint.

Frequently Asked Questions (FAQ)
Q1: How does this machine suck up the mud from the bottom? Does it need a massive, high-power pump?
A1: It does not need a high-power pump. The equipment operates on the "negative pressure principle" and "static water pressure". Due to the difference in water levels inside the pool and the discharge trough, natural water pressure automatically pushes the activated sludge from the bottom through the suction holes into the collection cylinder. This makes it incredibly energy-efficient.
Q2: What happens to the heavier, "inert" sludge at the bottom that cannot be sucked up?
A2: The design perfectly accounts for this. On the opposite side of the suction arm, there is a dedicated "scraping arm" equipped with "scraper blades". Any inert sludge that cannot be suctioned is gradually scraped into a central mud collection pit at the bottom of the pool, from where it is discharged separately, ensuring a thoroughly clean tank.
Q3: If the machine gets stuck at the bottom during 24-hour continuous operation, will the motor burn out?
A3: No. The equipment comes standard with a torque overload protection and overload alarm system. Whether it is running continuously for 24 hours or intermittently without human supervision, the protection system will immediately intervene if the resistance exceeds safe limits, absolutely guaranteeing the equipment's safety and reliability.
