Product Description
Discover the innovative functionality of our Knockout Barrel! As the mold of the sandbox ascends and reaches a specific altitude, it gracefully descends to the base of the streamlined chamber due to its own weight. Through a dynamic interplay of impact and friction, the sand mold and casting effortlessly part ways, smoothly traveling towards the chamber's grid via the spiral plates. This seamless transition ensures that the sand is efficiently directed into the old sand system, while the casting is expertly released through the discharge port, maintaining optimal workflow and precision.
In the sand-falling hub of the foundry workshop, the precise and effective separation of sand molds and castings is a game-changer for production rhythm and the excellence of old sand regeneration. Featuring a groundbreaking spiral guide system, this cutting-edge equipment redefines industry standards with its non-destructive separation of castings and precise recovery of old sand. By combining ingenious structural design with smart control technology, this article delves into how foundry enterprises can achieve pristine production conditions, cut costs, and boost efficiency. Through three pivotal breakthroughs—maximized gravitational potential usage, impeccable lossless separation of castings, and enhanced intelligent regeneration of used sand—this equipment stands as a trailblazing technical advancement for modern foundries.
1. Technical principle and core component design
Leveraging the inherent physical attributes of sand molds (with compressive strength ranging from 0.8-1.2MPa) and castings (weighing 50-5000kg), this system achieves remarkable separation efficiency through the harmonious marriage of gravitational impact and spiral guidance:
Rotation and tipping mechanism:
Propelled by a state-of-the-art servo motor, the sandbox elegantly rotates to a strategic angle of 45°-75° (with a margin of error of ±0.5°). Here, castings and sand molds impact the base plate of the simplified box under the powerful pull of gravity acceleration (between 4.5-6m/s²), culminating in an impressive initial separation efficiency of 98%.
The base of the simplified box is fortified with AR450 wear-resistant steel plate (20mm thick), amplifying impact resistance by a factor of 3 and ensuring a service life exceeding 5 years.
Spiral guide system:
This sophisticated multi-layer involute spiral plate system (with a pitch range of 300-800mm) orchestrates the sand flow into a vortex motion. It achieves secondary crushing through the particle friction (friction angle of 32°-35°), with an ultra-low molding sand residual rate of less than 0.5kg.
The guide plate's surface is enhanced with a laser-clad tungsten carbide coating (0.2mm thick), significantly minimizing friction coefficient to μ<0.15, making it perfect for various molding sands, including resin sand and water glass sand.
Intelligent sorting module:
Equipped with a dual-layer vibrating screen (apertures Φ5mm/Φ0.2mm), the old sand outlet adeptly separates iron bean impurities (>5mm) and micro powder (<0.2mm), achieving an impressive old sand regeneration qualification rate of over 95%.
The casting slide boasts a high-tech visual inspection system (featuring 5 million pixels) that continuously monitors casting integrity in real-time. Defective items are seamlessly redirected to the rework line, ensuring quality control and efficiency.
2. Process advantages and economic benefits
In comparison to traditional vibrating sand-falling machines, this system represents a transformative leap in efficiency, driven by energy optimization and a thoughtfully modular design:
Improved separation quality:
The casting surface residual sand is minimized to less than 0.3g/cm², a remarkable 80% reduction compared to pneumatic impact equipment. This results in a 60% reduction in subsequent cleaning costs.
The ignition loss (LOI) of old sand is meticulously controlled at ≤3.5%, boosting the reuse rate to an impressive 92%. Additionally, new sand replenishment needs are slashed by 50%.
Record-breaking low energy consumption:
Achieving an unrivaled gravitational potential energy utilization rate of 85%, power consumption per ton of casting separation is limited to ≤1.2kW·h, marking a substantial 45% energy saving over traditional vibrating sand-falling machines.
Rich in advanced innovation, this remarkable solution reduces impact noise to an impressively low level of ≤78dB(A). The dust concentration is meticulously controlled to remain under <5mg/m³, crafting a cleaner, safer environment. Witness an outstanding 70% reduction in environmental protection costs, paving the way for both ecological and economic benefits.
Experience unparalleled efficiency and ease of use with our Intelligent Operation and Maintenance System, a pioneering advancement in seamless machine management.
Our cutting-edge Predictive Maintenance Module vigilantly monitors bearing temperatures, setting an alarm threshold at 85ºC, and provides real-time insights into the vibration spectrum. Receive timely warnings of potential faults a full 7 days in advance, ensuring uninterrupted operation and peace of mind.
Harness the power of our state-of-the-art Digital Twin Platform, which expertly simulates the optimal tipping angle for varying casting weights ranging from 100 to 3000kg. Benefit from an impressively consistent separation efficiency, boasting a fluctuation rate of less than 2%, guaranteeing exceptional performance.
