Product Description
Vacuum Conveyor: Core Equipment for Dust-Free and Closed Conveying
I. Core Definition and Working Principle
A vacuum conveyor is a device that generates negative pressure through a vacuum pump and utilizes the pressure difference to achieve dust-free and closed conveying of granular and powdered materials. Its working process can be divided into three stages:Vacuum Generation
After the vacuum pump is started, it extracts air from inside the system, creating a negative pressure state in the suction nozzle and conveying pipeline.Material Suction
Under the effect of the pressure difference, the material mixes with air to form an airflow, which is then drawn into the vacuum hopper through the suction pipe.Air-Material Separation and Discharge
The material falls freely into the hopper under the action of gravity, while the air is discharged from the system through a filter, achieving air-material separation. The filter prevents the leakage of material dust, ensuring a clean working environment.II. Equipment Composition and Key Components
A vacuum conveyor consists of the following core components:Vacuum Pump
It provides the negative pressure power. Common types include vortex air pumps and Roots blowers. They need to be oil-free and water-free to ensure a pollution-free conveying process.Vacuum Hopper
It temporarily stores the sucked-in materials. The design should consider matching the volume with the material flowability.Filter
It separates the material from the air. The filter materials can be polyester coated, PE, 316L stainless steel, or titanium. Regular reverse blowing cleaning is required to maintain breathability.Reverse Blowing Device
It uses compressed air pulses to reverse blow the filter, removing adhered materials and ensuring stable system operation.Discharge Valve
It controls the flow of materials from the hopper. The common type is a pneumatic discharge gate, which supports automated control.Material Level Control Device
It uses sensors to monitor the material level in the hopper, enabling automatic start-stop of material feeding to avoid overflow or idle running.III. Technical Characteristics and Advantages
Dust-Free and Closed Conveying
The entire conveying process is enclosed in pipelines, eliminating dust leakage. It complies with GMP management requirements and is especially suitable for industries with strict hygiene standards, such as food and pharmaceuticals.High Space Utilization
The compact design of pipeline conveying allows it to adapt to narrow spaces and optimize workshop layouts.Flexible Conveying Distance
It is not limited by short or long distances and supports cross-floor or long-distance material transmission.High Degree of Automation
Through a PLC control system, it achieves precise control of the suction and discharge times. It supports linkage with upstream and downstream equipment, reducing manual intervention.Easy Maintenance
Modular design (e.g., quick-open clamp connections) facilitates disassembly and cleaning. The filter elements are replaceable, extending the equipment's service life.Corrosion-Resistant Materials
The parts in contact with the materials are made of 304 or 316L stainless steel, which is acid-resistant and corrosion-resistant, suitable for harsh environments in the chemical industry.IV. Application Areas and Industry Suitability
Vacuum conveyors are widely used in the following industries:Food Industry
They convey flour, starch, sugar, food additives, etc., improving production efficiency and reducing artificial contact pollution.Pharmaceutical Industry
They transport raw pharmaceutical materials, powdered drugs, and granular materials, ensuring the quality and safety of drug production.Chemical Industry
They convey pigments, dyes, fillers, etc., meeting the requirements of airtightness and explosion protection (which requires explosion-proof design).Plastics Industry
They transmit plastic granules, color masterbatches, and fillers, supporting the automation of injection molding and extrusion processes.New Energy Industry
They convey battery materials and solar panel materials, requiring high-precision control to ensure product performance.Agricultural Sector
They convey agricultural chemicals, feed, and fertilizers, promoting the automation of agricultural production.V. Selection and Usage Considerations
Material Characteristic Matching
Avoid conveying materials that are too moist, viscous, or heavy to prevent pipeline blockage or equipment damage.Operating Mode Selection
Choose fully automatic, semi-automatic, or manual equipment according to needs, balancing convenience and cost.Material and Workmanship Requirements
Prioritize stainless steel materials to ensure corrosion resistance and easy cleaning. Avoid thin-walled designs that may shorten the equipment's lifespan.Easy Maintenance
Select equipment with a simple structure and modular design for easy daily maintenance and filter element replacement.Industry-Specific Requirements
- Chemical Industry: Requires explosion-proof design and special alloy materials.
- Food and Pharmaceutical Industries: Requires a smooth surface for easy cleaning and food-grade stainless steel for contact parts.
- New Energy Industry: Requires a high-precision control system to support precise micro-conveying.
VI. Typical Application Cases
Pharmaceutical Enterprises
Vacuum conveyors are used to automate the conveying of raw pharmaceutical materials from storage tanks to reaction kettles, reducing artificial contact and the risk of cross-contamination.Food Factories
In flour conveying processes, vacuum conveyors are used in conjunction with dust removal systems to ensure that the air cleanliness in the workshop meets standards.Chemical Production Lines
When conveying corrosive pigments, titanium filters and explosion-proof vacuum pumps are selected to meet safety production requirements.
