Product Description
Furan resin sand reclamation lines are specialized systems for recycling used furan resin - bonded sand in foundries, mainly used to remove residual binders and impurities from old sand, enabling its reuse, reducing production costs and environmental pollution, and ensuring stable casting quality. Below is a detailed explanation of its application, composition, and capabilities.
Applications
Furan resin sand reclamation lines are widely used in foundries that produce castings with furan resin - bonded sand, especially in the following fields:
- Automotive Industry: For casting engine blocks, cylinder heads, transmission cases, and other complex components that demand high dimensional accuracy and surface finish.
- Heavy Machinery: Used for large - sized castings like frames, bases, and gearboxes, which require high mold strength and good collapsibility.
- Marine and Railway: Suitable for casting ship hull components, locomotive parts, etc., that have large sizes and complex structures.
- General Engineering Castings: Applicable to castings of steel, iron, aluminum, bronze, and other materials, especially those with high requirements for casting quality and cost control.
Composition
A typical furan resin sand reclamation line consists of the following key components, forming a continuous and automated processing system:
| Component | Function |
|---|---|
| Shakeout Device | Breaks down the used sand - mold after casting, separating castings from the used sand, and conveying the used sand to the reclamation process |
| Crushing and Regeneration Equipment | The core part, which removes the resin film on the sand surface through friction, impact, and shearing. Common types include vibrating crushing regenerators and centrifugal rotor regenerators. The centrifugal rotor regenerator can achieve a film - removal rate of over 95% |
| Magnetic Separator | Removes iron and steel impurities from the reclaimed sand to avoid affecting the casting quality |
| Screening Equipment | Screens the sand to ensure uniform particle size and remove large sand lumps and debris |
| Air Classification System | Uses cyclones and pulse dust collectors to eliminate fine powder and dust, improving the quality of the reclaimed sand |
| Cooling System | Cools the high - temperature reclaimed sand (≤300℃) to meet the requirements of subsequent sand mixing, and some equipment combines cooling with regeneration |
| Sand Storage and Supply System | Stores the qualified reclaimed sand and supplies it to the sand mixer as needed |
| Sand Mixer | Mixes the reclaimed sand with furan resin, curing agent, etc., in a certain proportion to prepare molding sand that meets the process requirements |
| PLC Control System | Realizes automatic control of the entire line, including parameters such as material flow, regeneration time, and additive dosage, to ensure stable and reliable operation |
Capabilities
- High Sand Reclamation Rate: The reclamation rate can reach more than 90% - 95%, which significantly reduces the consumption of new sand and the cost of waste sand disposal.
- Excellent Film - Removal Effect: The film - removal rate is over 95%, and the surface of the reclaimed sand is smooth with uniform particle size distribution and less fine powder, which can save more than 20% of resin and reduce casting defects such as veining and mechanical sand sticking.
- Stable Sand Performance: The reclaimed sand has good thermal stability, low thermal expansion, and stable chemical properties, which is conducive to controlling the quality of castings and improving the surface finish of castings.
- Environmental Protection and Energy Conservation: It reduces the emission of waste sand and dust, and the dust emission concentration meets national standards. At the same time, it saves energy and reduces production costs compared with using new sand.
- Strong Adaptability: It can handle used furan resin sand at different temperatures and with different degrees of hardening. It can also be adapted to the reclamation of sodium silicate sand, and the production capacity can be customized according to the scale of the foundry, generally ranging from 5 to 20 t/h.
- Automation and Intelligence: The PLC control system enables automatic operation, reduces manual intervention, improves production efficiency, and ensures the stability of the reclamation process.
