Product Description

ABRASIVE VACUUM RECOVERY SYSTEM - Model N90VR

Designed as two units: main unit and dust removal unit. The sand suction tank acts as a shot recycling tank, connecting the two units via hoses. All internal electrical parts are pre-installed for immediate use with standard power and air supplies.

Key System Components:

Main Unit: Vacuum pump, electric motor, and silencer.
Dust Removal Unit: Cyclone dust collector, cartridge dust collector, and blowing valve.
Sand Suction Tank: Gravity separation system with material leveler.
Control System: PLC full-automatic program control for seamless operation.
Core Technology: Roots vacuum pump and high-efficiency filter cartridge material.

Application

This negative pressure pneumatic conveying equipment is specifically designed for recycling sandblasting granules. The integral sand suction machine is ideal for shipbuilding painting plants, featuring a steel-welded frame with lugs for lifting and forklift holes for easy transport and mobility.

Working Principle & Features

Working Principle: High-vacuum suction through a nozzle creates a pneumatic flow that transports abrasive material to the gravity separation tank. Sand remains in the tank while air is filtered through cyclone and cartridge collectors before being exhausted through a silencer. The PLC detects when the tank is full, automatically halting suction and discharging sand via an automatic valve.

Safety & Operational Highlights

Multiple protections: Motor overload, vacuum overload, and phase sequence protection.
Inlet protective net prevents foreign objects from damaging the vacuum pump.
Dual cleaning modes: Manual and automatic time interval pulse blowing.
Independent control power switch for testing without engaging the main power.

Quality Assurance and Service

Rigorous management and inspection processes to eliminate detail errors.
Advanced factory facilities and robust design capabilities.
Comprehensive inspections including incoming material and flaw detection.
24-hour response time for technical inquiries and efficient solutions.
Professional customization services tailored to specific client needs.
On-time delivery driven by a strict production schedule.

Frequently Asked Questions

Q1: What materials can the N90VR recovery system handle? A1: It is specifically designed for the recovery of various sandblasting granules used in industrial coating and shipbuilding.

Q2: How does the automatic sand discharge function work? A2: When the storage tank is full, a PLC signal triggers the automatic valve to release the sand, and the system resumes suction once the cycle is complete.

Q3: What are the noise levels during operation? A3: The system is equipped with a silencer to keep noise levels at or below 85dB(A), ensuring compliance with industrial standards.

Q4: Is the system mobile or fixed? A4: It is available in both integral (mobile) and split fixed types. The mobile versions include forklift holes and lifting lugs for easy relocation.

Q5: What maintenance is required for the dust collectors? A5: The system features automatic pulse blowing cleaning for the cartridge filters, significantly reducing the need for manual maintenance.

Q6: Can the technical parameters be customized? A6: Yes, we provide professional customization services to adjust air volume, storage capacity, and power configurations according to your specific requirements.
