Sludge Drainage System (Sedimentation Basin)

 

Enclosure may vary depending on the specifications of the product (water-proof/explosion-proof, Single-Phase/Three-Phase Power).

Description

RPMTECH's Sludge Drainage System is comprised of an efficient auxiliary scrapper (attachment) and a fail-safe MHP (or DHP) Quarter-Turn Actuator (s) attached to a segmented ball valve. The auxiliary scraper attachment and the immediate opening/closing of the ball valve allows for resistance-free (Rabbit-Hole-free) drainage, which helps reduce sludge solidification within the hopper. Also, the actuator is equipped with advanced control modes optimized for efficient drainage and valve disk protection.

Features

  • Compact, All-in-one Electro-Hydraulic Actuator

  • Does not require gearbox: direct power delivery (high efficiency)

  • Modular design (easy maintenance)

  • Equipped with patented manual hand pump

  • Various installation types (able to install actuator and hydraulic cylinder separately for safety and ease of use)

  • Limit settings and parameter settings are easily accessible

  • Self-diagnosis capabilities and password lock for added security

  • Various advanced control modes (refer below to Control Modes)

  • Audible and visible alarm during abnormality

  • Supports various communication platforms (AIO/DIO, Profibus, etc.)

Specifications

  • Power: Single-Phase AC 110~220V (50/60 Hz) or Three-Phase AC 380~460V (50/60Hz)

  • Enclosure Rating: IP68 Water-proof or Exd II B T4 Explosion-proof

  • Motor Specs: Bidirectional 0.6kW BLDC Motor (DHP Series: 1.2 kW)

  • Torque Range: 600 Nm ~ 32,000 Nm (Contact for higher torque)

  • Minimum Open/Close Time by torque:

MHP Quarter-Turn Actuator

Summary

 

Sludge Drainage System (Sedimentation Basin)

Efficient Sludge Drainage System for the Sedimentation Basin (water treatment)

Prevents Sludge Solidification

Efficient Sludge Extraction

Reduced Costs

Many sludge collectors (scrapers) have blind spots within the hopper, which means that sludge can be left uncollected only to solidify within the sedimentation basin. RPMTECH's auxiliary sludge scraper attachment can effectively prevent this by reducing any blind spots in the hopper.

RPMTECH's MHP/DHP Quarter-Turn Actuators are capable of opening/closing the valve in 5~8 seconds or less. Immediate opening of the valve will allow the sludge to immediately whirl down the drain resulting in a more efficient and immediate drainage process. This will prevent the formation of rabbit holes, which is the cause of inefficient drainage.

Sludge moisture content 1.71%P decrease, unnecessarily wasted water 42.6% decrease, sludge drainage efficiency 48.7%. These statistics are the start to reduced installation and operation costs in the long run.
