II. Core Functions & Technical Highlights
1. Integrated Slurry Treatment Workflow
Integrates purification – circulation – storage – mixing in one unit, eliminating the need for external storage tanks or mixing equipment (unlike traditional separate systems). Enables closed-loop slurry lifecycle management:
- Pre-treatment: Bottom coarse screen of shale shaker intercepts large drill cuttings;
- Deep Purification: 4 polyurethane cyclones with symmetric inflow separate fine particles >15 μm via centrifugal force;
- Recycling: Purified slurry is reconditioned by the mixing device and pumped back directly to the drilling system;
- Auto Level Control: Built-in float device in storage tank automatically maintains stable liquid level to prevent overflow risks.
2. Structure Optimized for Confined Spaces
- Foldable Modular Design: Walkways and guardrails can be quickly detached and folded for transport via standard trucks, improving relocation efficiency by 50%;
- Compact Tank Layout: Integrates desilter and shale shaker in one unit, achieving a complete treatment process within 5 m³—perfect for urban old districts, highway green belts, and other narrow sites;
- Easy Maintenance: Cyclones use clamp-type connections; screen mesh features soft-hook edges for single-person replacement within 15 minutes.
3. Safety, Environmental Protection & Operational Assurance
- Low-Noise Operation: Shaker system noise ≤85 dB, compliant with urban construction noise standards;
- Safety Protection: Electrical system features triple protection (explosion-proof, dust-proof, rain-proof), certified by API and ISO 14001;
- Environmental Compliance: Reduces waste slurry discharge by 90%, meeting Technical Specifications for Environmental Protection in Trenchless Construction.
III. Typical Applications & Case Adaptability
1. Core Applicable Project Types
- Small-to-medium horizontal directional drilling (HDD): urban gas/water supply branch lines, residential communication pipe installations, and other short-distance crossings;
- Space-constrained projects: pipeline construction in highway medians, underground works near heritage buildings;
- Auxiliary slurry treatment: branch line construction for large HDD projects, slurry purification in river dredging sites.
2. Scenario Adaptability Advantage
Taking urban old community pipeline renovation as an example: the KSMR-200 can be deployed directly in community green space (5 m² footprint ≈ 2 parking spaces). With 50 m³/h capacity, it meets slurry demands for 80 m of daily pipeline installation. Achieves 92% recovery rate, saving approximately CNY 23,000 in slurry costs per project.
IV. Differentiated Advantages vs. Series Models & Competitors
| Comparison Dimension | KSMR-200 | KSMR-500 (Same Series) | Traditional Separate System |
| Applicable Scenarios | Small-to-medium projects, narrow sites | Large-scale crossing projects | Large sites, fixed operations |
| Equipment Volume | 5 m³ | 12 m³ | >20 m³ |
| Relocation Cost | Standard truck transport | Heavy-duty truck transport | Multi-vehicle split transport |
| Installation Time | 2 hours for commissioning | 4 hours for commissioning | 8+ hours for installation & commissioning |
| Compatible Slurry Types | Water-based mud, bentonite mud | All mud types compatible | Requires customized slurry adaptation |
V. Operating Cost & Benefit Analysis
For a typical 1,000 m pipeline project (Ø300 mm):
- Material Cost: 90% recovery rate reduces fresh slurry procurement by ~100 m³, saving CNY 30,000 ;
- Labor Cost: Integrated operation reduces 3 on-site operators, saving CNY 12,000 ;
- Environmental Cost: Reduces waste slurry discharge by 100 m³, mitigating penalty risks and cutting disposal fees by CNY 15,000 ;
- Overall Benefit: Direct cost savings of CNY 57,000 per project, with 15% shorter project duration.
