KSMR-500 Trenchless Slurry Recovery System

I. Core Performance Parameters

Based on the product parameter gradient of the Black Rhino KSMR Series and the requirements of mid-to-large scale engineering construction, the core performance parameters of KSMR-500 are as follows:

II. Core Functions & Technical Highlights

1. High-efficiency Integrated Treatment Process

Based on the core functions of the series products, it is upgraded and optimized for mud processing demands of medium-to-large scale projects, achieving stable closed-loop treatment under high load:

• Enhanced Pre-treatment: Adopts double-layer high-frequency shale shaker, with upper coarse screen intercepting large drill cuttings ≥74 μm and lower fine screen pre-treating fine particles of 15–74 μm, screen area reaches 4.8 m², 50% higher than KSMR-350 (3.2 m²), significantly improving pre-treatment efficiency.
• Upgraded Deep Purification: Equipped with 16 polyurethane cyclones using symmetric dual-inlet structure, centrifugal force stably maintained at 1000G (between KSMR-350’s 800G and KSMR-1000’s 1200G), fine particle separation efficiency 30% higher than KSMR-350, ensuring purification effectiveness for high sand-content mud.
• Intelligent Circulation Control: Integrated semi-automatic + fully automatic dual-mode mixing system, real-time monitoring of mud performance through high-precision inline densitometer and viscometer, automatic or manual replenishment of bentonite, polymers and other materials, mixing uniformity reaches 97%, adaptable to different operator habits.
• Multi-level Intelligent Control: Main storage tank and buffer tank equipped with radar level gauge and float level gauge respectively, dual monitoring and feedback, automatically regulating mud input/output flow, effectively preventing overflow risks under high processing capacity of 120 m³/h.

2. Structure Design Adapted for Medium-to-Large Scale Projects

• Modular Combined Architecture: Equipment divided into three major units: “shale shaker + cyclone” purification module, “storage + power” support module, and “mixing + circulation” auxiliary module, can be split for transport and assembled on-site through quick connectors, 2 heavy-duty trucks can complete relocation, 30% more efficient than KSMR-1000.
• High-strength Stable Design: Tank made of Q345B high-strength steel, wall thickness 10 mm (between KSMR-350’s 8 mm and KSMR-1000’s 12 mm), bottom equipped with reinforced adjustable support feet, can withstand long-term mud impact at 120 m³/h, adaptable to non-hardened construction sites, service life exceeds 14 years.
• Upgraded Easy Maintenance: Cyclones use quick-disconnect flange connections with automatic flush pipelines to reduce impurity residue; shale shaker equipped with hydraulic automatic tensioning mechanism, screen replacement time shortened to 25 minutes, 17% time-saving compared to KSMR-350 (30 minutes), reducing maintenance intensity.

3. Safety, Environmental Protection & Operational Assurance

• Low-noise Operation Optimization: Shale shaker adopts air spring + rubber composite shock absorption design, operating noise controlled below 83 dB (between KSMR-350’s 84 dB and KSMR-1000’s 82 dB), compliant with noise standards for urban periphery and large construction sites.
• Comprehensive Safety Protection: Electrical system upgraded to Exd II BT4 explosion-proof rating, equipped with four-level interlock protection for temperature, pressure, level, and current, automatically shuts down, alarms and records fault information when abnormalities occur for quick troubleshooting, certified by API 13C, ISO 9001, and CE triple international certifications.
• Deep Environmental Adaptation: Built-in simple drill cuttings dewatering device can reduce cuttings moisture content below 25%, solid waste reduction by 60%, while reserving interface for external deep drying module for upgrade according to environmental requirements, meeting solid waste treatment standards in different regions and complying with the Environmental Protection Law and local environmental regulations.

III. Typical Applications & Case Adaptability

1. Core Applicable Project Types

• Medium-to-long distance horizontal directional drilling: Inter-city natural gas trunk lines, large water supply pipeline installation (length 3,000–5,000 m), highway/railway trunk line crossing projects and other medium-to-long distance construction.
• Large-diameter pipeline construction: Municipal sewage trunk pipes (diameter 800–1,500 mm), industrial transfer pipeline installation and other high-flow slurry demand scenarios.
• Complex geological medium-to-large scale projects: Coalbed methane extraction in mixed sand-clay layers, medium-scale shale gas drilling mud treatment, and large industrial park underground pipeline network construction.

2. Scenario Adaptability Advantage

Taking an inter-city natural gas trunk line crossing project (length 4,000 m, pipe diameter 1,200 mm) as an example: The KSMR-500 meets slurry demands for 180 m of daily pipeline installation through its 120 m³/h processing capacity, achieving 92% mud recovery rate. Per project, it reduces fresh mud procurement by 800 m³, saving approximately CNY 280,000 in costs. Drill cuttings processed by the built-in dewatering device can be directly handed over to professional agencies for disposal, reducing solid waste transport volume by 600 tons and saving disposal fees of CNY 120,000, while avoiding environmental risks from exceeding solid waste standards.

IV. Differentiated Advantages vs. Series Models & Competitors

V. Operating Cost & Benefit Analysis

Taking a single 4,000 m larger-diameter (1,200 mm) pipeline project as an example:

• Material Cost: 92% mud recovery rate reduces fresh mud procurement by 1,200 m³, calculated at market average price of CNY 350/m³, saving CNY 420,000 in costs.
• Labor Cost: Dual-mode control requires only 3 operators, reducing 2 on-site personnel compared to traditional systems (which require 5), calculated at daily wage of CNY 300/person and 60-day construction period, saving CNY 36,000 in labor costs.
• Environmental Cost: Built-in dewatering device treats drill cuttings, reducing solid waste transport volume by 900 tons, calculated at disposal fee of CNY 200/ton, cutting disposal costs by CNY 180,000, while avoiding potential fine risks of CNY 50,000–100,000 from exceeding solid waste standards.
• Overall Benefit: Direct cost savings of CNY 636,000 per project, construction efficiency 25% higher than traditional systems, project duration shortened by 30 days, indirectly reducing additional costs from schedule delays.
