Product Description
Introducing the advanced S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a marvel in sand grain rejuvenation. This innovative machine employs a robust double-axis mechanism that expertly eliminates the resin curing agent lingering on the surface of sand grains through dynamic rubbing and sophisticated de-filming processes.
Enhancing its efficiency, the machine's base is ingeniously fitted with a high-performance fan that expertly separates lingering old film and dust, ensuring pristine cleanliness. After this meticulous treatment, the rejuvenated old sand boasts an impressive level of integrity and beautifully rounded grains. This enhanced quality significantly diminishes the need for additional liquid materials during subsequent mixing, promising a more cost-effective and efficient process. Experience the future of sand recycling with the S53 Scrubber Recycling Machine.
As the core equipment for the regeneration of foundry old sand, the strong rubbing regeneration machine realizes the efficient stripping and regeneration of old sand such as resin sand and water glass sand through the synergistic effect of dual-axis mechanical rubbing and airflow assistance. The following is a detailed analysis from the aspects of technical principles, structural design, process flow and actual application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine uses two sets of transmission main shafts to rotate in opposite directions at high speed (the speed can reach 720-970r/min), and wear-resistant alloy blades or cast iron rubbing discs are installed on the shaft. After the sand enters the regeneration chamber, it undergoes repeated rubbing and collision under the linear shear force and convection of the blades. This mechanical action not only strips off the resin film and curing agent on the surface of the sand, but also achieves surface rounding through friction between the sand particles, reducing edge damage. Compared with the traditional three-axis structure, the dual-axis design optimizes the chamber space, increases the material throughput by 10-30t/h, and reduces energy consumption at the same time.
2. Boiling airflow assists film stripping. The bottom blower (air volume > 3700m³/h) injects adjustable airflow into the chamber through the boiling orifice plate to form a fluidized environment of sand and air mixing. On the one hand, the airflow enhances the collision frequency between sand particles, and on the other hand, the detached inert film and dust are discharged through the dust removal vent. This "mechanical + airflow" dual effect increases the film stripping rate to more than 80%, and the sand temperature can be reduced by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade adopts the carbide convex rib welding process, and the wear resistance is increased by more than 3 times; the chamber body and the frame are connected by rubber elasticity to effectively suppress the vibration caused by high-speed operation and ensure the stability of the equipment.
4. Applicable sand mold and regeneration effect
Furan resin sand: The brittle resin film can be removed by rubbing for 180 seconds, the burning loss is less than 1.0%, and the tensile strength of the regenerated sand is restored to 90% of the new sand.
Water glass sand: It needs to be combined with wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal process (-40ºC), but dry regeneration as pretreatment can reduce the subsequent wet load.
Alkali phenolic resin sand: The tough film requires higher rubbing strength (such as wheel rolling pressurization), the roundness of the sand particles is improved after regeneration, and the gas emission is reduced by 30%.
5. Technical advantages and economy
The regeneration efficiency is improved. Compared with the traditional centrifugal regeneration machine (power 22kW/stage) or air flow impact equipment, the unit energy consumption of the double-axis regeneration machine is reduced by 40%, and the sand particle crushing rate is controlled within 5%, and the integrity is better than vibration regeneration.
Production cost optimization, the resin active film residue of the regenerated sand (<0.3%) can reduce the amount of curing agent added by 30%-50% when mixing sand, and the sand-iron ratio is reduced from 1:1 to 1:1.5, which significantly reduces the cost of purchasing new sand.
Environmental compatibility, dry regeneration without wastewater discharge, dust is centrally processed by pulse back-blowing dust removal system (dust removal efficiency > 99%), which meets the ultra-low emission standards of the foundry industry.
