Product Description
Introducing the groundbreaking S53 Scrubber Recycling Machine, a testament to innovation by Qingdao Sanzhuji Technology Co., Ltd. This state-of-the-art equipment stands as a pinnacle in the rejuvenation of sand grains, harnessing an unparalleled double-axis mechanism. With expert precision, it effortlessly eradicates the residual resin curing agent that clings to the surface of sand grains. Through dynamic rubbing and advanced de-filming processes, this machine sets a new standard in sand refinement.
Elevating efficiency to new heights, the machine's foundation is thoughtfully equipped with a high-efficiency fan. This expertly engineered component brilliantly separates residual old film and dust, ensuring an unparalleled level of cleanliness. Post meticulous treatment, the revitalized old sand exhibits an impressive integrity and artfully rounded grains. This superior quality significantly reduces the necessity for additional liquid materials during subsequent mixing, fostering a more cost-effective and streamlined process. Embrace the future of sand recycling with the remarkable S53 Scrubber Recycling Machine.
As the cornerstone of foundry old sand regeneration, the robust rubbing regeneration machine excels in the efficient stripping and renewal of old sand types including resin sand and water glass sand. Capitalizing on the harmonious interaction of dual-axis mechanical rubbing and airflow assistance, this machine showcases its prowess. The following provides an in-depth analysis across technical principles, structural design, process flow, and real-world application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine is equipped with two sets of transmission main shafts that rotate in opposite directions at high speeds, reaching an impressive 720-970r/min. Outfitted with wear-resistant alloy blades or cast iron rubbing discs, these shafts deliver unmatched performance. As sand enters the regeneration chamber, it undergoes repeated rubbing and collision, driven by the linear shear force and convection of the blades. This mechanical action expertly strips the resin film and curing agent from the sand surface while achieving surface rounding through inter-particle friction, minimizing edge damage. Compared to the traditional three-axis setup, the dual-axis design optimizes chamber space, elevating material throughput by 10-30t/h, and simultaneously reducing energy consumption.
2. Boiling airflow assists film stripping. The bottom blower, boasting an air volume exceeding 3700m³/h, channels adjustable airflow into the chamber via the boiling orifice plate, creating a fluidized blend of sand and air. This dual-action airflow not only amplifies collision frequency among sand particles but also efficiently expels detached inert film and dust through the dust removal vent. This synergy between mechanical and airflow effects elevates the film stripping rate to over 80%, while reducing sand temperature by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade employs advanced carbide convex rib welding techniques, enhancing wear resistance by more than threefold. The chamber body and frame are seamlessly connected through rubber elasticity, effectively damping vibrations resulting from high-speed operations and ensuring steadfast equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: The fragile resin film can be efficiently removed within 180 seconds of rubbing, boasting a burn loss of less than 1.0%, while restoring the tensile strength of the regenerated sand to 90% of new sand standards.
Water glass sand: Requires integration with wet regeneration (sand-water ratio 1:1.5) or a low-temperature freezing centrifugal process (-40ºC). However, employing dry regeneration as a pretreatment can effectively reduce the subsequent wet load.
Alkali phenolic resin sand: The robust film demands higher rubbing intensity, such as wheel rolling pressurization. Post-regeneration, sand particle roundness is enhanced, and gas emissions are decreased by 30%.
5. Technical advantages and economy
Regeneration efficiency has been remarkably enhanced. In comparison to conventional centrifugal regeneration machines (power 22kW/stage) or air flow impact equipment, the unit energy consumption of the double-axis regeneration machine is slashed by 40%. The sand particle crushing rate is meticulously managed within 5%, offering integrity superior to vibration regeneration methods.
Unleash the power of cost optimization with our advanced solution! By expertly minimizing the resin active film residue in regenerated sand to an impressive less than 0.3%, our process masterfully reduces the need for curing agents by a remarkable 30% to 50% during sand mixing. Moreover, experience the economy of scale as the sand-iron ratio transforms from 1:1 to a more efficient 1:1.5. The result? A substantial decrease in the expenditure on new sand, driving down costs effectively while maintaining superior quality.
Embrace a greener future with our environmentally compatible innovation! Our dry regeneration technology eliminates wastewater discharge entirely, aligning perfectly with eco-friendly practices. The state-of-the-art pulse back-blowing dust removal system, boasting an exceptional dust removal efficiency of over 99%, ensures that dust is processed centrally and meets the stringent ultra-low emission standards demanded by the foundry industry. Join us in setting new benchmarks for environmental responsibility and operational excellence.
