The environmentally friendly vibration shell machine is a device designed specifically for investment casting (lost wax casting) processes. It is used to remove the outer shell (ceramic shell or gypsum shell) wrapped around the casting through vibration or impact, and has environmental characteristics such as low noise, low dust, energy saving and high efficiency.
1. Equipment structure and working principle
(1) Core components
--Vibration system:
Electric/pneumatic vibrator: Provides high-frequency vibration (adjustable frequency, usually 500~3000 times/minute).
Shock absorber device: Rubber or spring shock absorber to reduce the impact of equipment on the foundation.
--Sealed dust removal system:
Closed working chamber: prevents dust from escaping.
Dust collection device: equipped with cyclone dust removal or bag filter, can be connected to the central dust removal system.
--Automated control:
PLC controls vibration time and frequency, and some models support automatic feeding/discharging.
(2) Workflow
Loading: Place the shell castings into a vibrating worktable (which can be manually or automatically loaded by a robotic arm).
Vibration shedding: High frequency vibration causes the shell to break and fall off, while the dust removal system collects debris.
Discharge: The shelled castings enter the next process (such as shot blasting, acid washing).
2. Environmental characteristics
Environmental Design: Specific Measures
Low noise: Equipped with soundproof covers and shock-absorbing bases, the noise level is ≤ 75dB (traditional vibrating shell machines can reach over 90dB).
Dust control: enclosed structure+high-efficiency dust removal (filtration efficiency ≥ 99%), in compliance with OSHA/EPA standards.
Energy saving: Variable frequency motor/pneumatic optimization reduces energy consumption by 20% to 30% compared to traditional models.
No chemical pollution: pure physical shelling, avoiding the use of chemical shelling agents (such as hydrofluoric acid).
