KSMR-1000 Trenchless Slurry Recovery System

I. Core Performance Parameters

Based on the product parameter gradient of the Black Rhino KSMR Series and the requirements of large-scale engineering construction, the core performance parameters of KSMR-1000 are as follows:

II. Core Functions & Technical Highlights

1. Enhanced Integrated Treatment Process

Optimized and upgraded from the KSMR series’ base functions, achieving full-process closed-loop processing of ultra-large mud volumes, adaptable to complex geological construction requirements:

• Upgraded Pre-treatment: Adopts double-layer high-frequency shale shaker, with upper coarse screen intercepting particles ≥74 μm and lower fine screen pre-treating 15–74 μm particles. Screen area reaches 6.5 m², 3 times the processing efficiency improvement.
• Enhanced Deep Purification: Configured with 20 oversized polyurethane cyclones using symmetric dual-inlet structure, centrifugal force increased to 1200G, fine particle separation efficiency 40% higher than KSMR-200.
• Intelligent Circulation Control: Integrated fully automatic mixing system, real-time monitoring of mud performance through inline densitometer, automatically replenishing bentonite, polymers and other materials, mixing uniformity reaches 98%.
• Multi-level Linkage Control: Both main storage tank and buffer tank equipped with high-precision float + radar level meters, dual feedback regulation prevents overflow risks under high-flow conditions.

2. Large-scale Project Adapted Structural Design

• Modular Combined Architecture: Equipment divided into four units: shale shaker module, cyclone module, storage module, and power module. Can be split for transport and quickly assembled on-site, relocation requires only 2 heavy-duty trucks.
• High-strength Load-bearing Design: Tank made of Q345B high-strength steel with wall thickness up to 12 mm, bottom equipped with reinforced support feet, can withstand long-term 240 m³/h mud impact, service life exceeds 15 years.
• Upgraded Easy Maintenance: Cyclones use quick-disconnect flange connections with automatic flush device; shale shaker equipped with hydraulic tensioning mechanism, screen replacement time shortened to 20 minutes, 50% time-saving compared to traditional equipment.

3. Intelligent Safety & Environmental Protection Guarantee

• Low-noise Intelligent Operation: Shale shaker adopts air spring shock absorption + noise reduction cover design, operating noise controlled below 82 dB, 3 dB lower than KSMR-200.
• Multi-dimensional Safety Protection: Electrical system upgraded to Exd II BT4 explosion-proof rating, equipped with triple interlock protection for temperature, pressure, and liquid level, automatically shuts down and alarms when abnormalities occur, certified by API 13C and ISO 9001 dual international certifications.
• Deep Environmental Compliance: Equipped with mud drying module, waste cuttings moisture content reduced below 15%, solid waste reduction by 70%, fully compliant with Soil Pollution Prevention Law requirements, directly transportable for disposal.

III. Typical Applications & Case Adaptability

1. Core Applicable Project Types

• Ultra-long distance horizontal directional drilling: Large-scale pipeline installation crossing rivers (such as natural gas trunk lines, crude oil pipelines), railway/highway crossing projects and other long-distance (3000 m) construction.
• Large-diameter pipeline construction: Water supply trunk pipes (diameter ≥1200 mm), municipal sewage pipeline installation and other high-flow mud demand scenarios.
• Complex geological projects: Energy extraction (shale gas, coalbed methane) drilling mud treatment in complex geological conditions such as sand layers and gravel layers, as well as tunnel construction in large mining areas.

2. Scenario Adaptability Advantage

Taking a river-crossing natural gas trunk line crossing project (length 3,500 m, pipe diameter 1,400 mm) as an example: The KSMR-1000 meets slurry demands for 200 m of daily pipeline installation through its 240 m³/h processing capacity, achieving 93% mud recovery rate. Per project, it reduces fresh mud procurement by 1,200 m³, saving approximately CNY 450,000 in costs. Meanwhile, the dried cuttings can be directly recycled as road construction materials, creating additional benefits of CNY 80,000.

IV. Differentiated Advantages vs. Series Models & Competitors

V. Operating Cost & Benefit Analysis

Taking a single 5,000 m large-diameter (1,400 mm) pipeline project as an example:

• Material Cost: 92% mud recovery rate reduces fresh mud procurement by 1,800 m³, saving CNY 630,000 in costs.
• Labor Cost: Fully automatic control requires only 2 operators, reducing 5 on-site personnel compared to traditional systems, saving CNY 42,000 in labor costs.
• Environmental Cost: Drill cuttings drying treatment reduces solid waste transport volume by 1,200 tons, cutting disposal fees by CNY 240,000 and avoiding environmental penalty risks.
• Overall Benefit: Direct cost savings of CNY 912,000 per project, construction efficiency improved by 30%, project duration shortened by 45 days.
