Traveling Bridge Sludge Scraper & Suction Collector with Anti Sludge Resuspensio

Product Specification

Traveling Bridge Sludge Scraper & Suction Collector with Anti Sludge Resuspension for Rectangular Sedimentation Tanks

Brief Description

Traveling Bridge Sludge Scraper and Traveling Bridge Sludge Suction Collector are two separate wastewater treatment devices, commonly used for sludge and floating scum removal in rectangular horizontal flow sedimentation tanks. Users may choose either model based on actual working conditions: the scraper type is mostly applied to primary sedimentation tanks and grit chambers; the suction type is preferred for continuous sludge withdrawal in secondary sedimentation tanks and waterworks sedimentation tanks, and scum skimming devices can be configured on demand.

Product Overview

This series covers two independently operated Traveling Bridge sludge removal units, optimized for rectangular horizontal flow tank structures and NOT suitable for standard circular radial sedimentation tanks. Each model operates independently; customers can select one single unit based on treatment requirements, and no mandatory package combination is required.

1. Traveling Bridge Sludge Scraper

The machine runs against the water flow to collect deposited sludge and sand, while floating scum is collected and drained along the water flow direction. The scraping rake will be lifted automatically during the return stroke to greatly reduce resuspension of settled sludge, realizing continuous cyclic sludge and scum removal.

2. Traveling Bridge Sludge Suction Collector

Suitable for rectangular secondary clarifiers of municipal wastewater plants and horizontal flow sedimentation tanks of waterworks. It adopts siphon or pump suction sludge discharge modes to continuously extract bottom sludge under normal operating conditions. Optional oil and scum skimming assemblies can be equipped for comprehensive removal of floating surface residues.

Note: Traveling Bridge Sludge Scraper and Traveling Bridge Sludge Suction Collector are standard separate models. The integrated scraping & suction combined version belongs to customized non-standard equipment.

Working Principle

1. Traveling Bridge Sludge Scraper

The equipment consists of traveling bridge, drive system, track and wheel assembly, winch lifting unit, electric actuator scum rake, scraping rake and safety guardrail system. During forward travel, the rake descends to push sludge and scum towards discharge hoppers. On the return stroke, the whole rake frame is lifted to avoid resuspending settled sludge. The bottom scraping rake is lifted and lowered by winch, while the scum rake is controlled separately via electric actuator to guarantee thorough cleaning performance.

2. Traveling Bridge Sludge Suction Collector

Built upon mobile traveling bridge structure, it provides two practical sludge suction solutions adapting to different civil tank designs. The siphon type suits above-ground rectangular sedimentation tanks, while pump suction version fits semi-underground rectangular tanks. The traveling bridge drives multiple suction pipelines to discharge settled sludge evenly and continuously from tank bottom.

Key Design & Performance Features

1. Two independent types for flexible selection

Scraper type and suction type are fully standalone equipment; single-unit procurement is supported to match different clarifier treatment processes.

2. Anti-sludge resuspension scraping design

Automatic rake lifting during return travel greatly inhibits sludge resuspension, stabilizing sedimentation performance and guaranteeing consistent outlet water quality.

3. Dual sludge suction options for wide adaptability

Siphon and pump suction versions optional, compatible with above-ground and semi-underground tank civil structures.

4. Corrosion-resistant durable construction

Thickened carbon steel with epoxy anti-corrosion coating, or full SUS304 / SUS316 stainless steel available, suitable for municipal and diverse industrial wastewater environments.

5. Synchronized bilateral drive for stable running

Dual-side synchronous traveling design minimizes deviation and jamming risks, and can realize long-term unattended automatic operation when matched with complete electrical protection systems.

6. High flexibility for customized configuration

Optional scum & oil skimming device, PLC automatic control cabinet and remote monitoring system to satisfy personalized project demands.

7. Low operation & maintenance cost

Simplified mechanical structure with fewer wearing parts, convenient routine inspection and lower long-term operational expenditure.

Applications

1. Traveling Bridge Sludge Scraper Application

Municipal wastewater primary sedimentation tanks, water plant grit chambers, industrial washing wastewater sedimentation tanks, construction mud & sand pretreatment tanks.

2. Traveling Bridge Sludge Suction Collector Application

Municipal secondary sedimentation tanks, tap water purification plants, food, textile, printing & dyeing industrial wastewater treatment stations.

3. General Applicable Industries

Municipal water supply & drainage, industrial wastewater treatment, mine washing water treatment, rural centralized sewage treatment and environmental upgrading reconstruction projects.
