Vacuum Conveyor

Product description

Continuous vacuum feeder is mainly composed of vacuum pump system, feeding device, pipeline, discharge device and control system. Its working principle is to rely on the vacuum pump to build a vacuum or negative pressure environment in the pipeline, the external atmospheric pressure to promote the material from the inlet into the pipeline, and driven by the negative pressure air flow to the discharge position, through the gas-solid separation device to achieve the separation of material and gas to complete the discharge process. The equipment has many advantages, efficient transportation and clean environmental protection, can effectively protect the quality of materials, high degree of automation can be flexible layout, widely used in chemical, food, pharmaceutical, plastics and other industries, suitable for a variety of forms of material transportation, while maintenance is simple, safe and reliable.

Working principle

When the continuous vacuum feeder is working, the vacuum pump starts first and quickly draws the air in the pipeline, so that the internal pressure of the pipeline is sharply reduced, forming a vacuum or negative pressure environment significantly lower than the external atmospheric pressure, and this pressure difference becomes the core driving force for material transportation; At the feeding end, because the external atmospheric pressure is much higher than the pressure in the pipeline, the material can overcome its own gravity and friction with the inlet around the inlet under the action of pressure difference and enter the pipeline smoothly from the inlet. At the same time, the precision control components such as the level sensor and the inlet valve in the feeding device accurately control the inlet amount and frequency of the material according to the preset parameters to ensure the stable and accurate feeding. After entering the pipeline, the material is bound by the high-speed flow of negative pressure air, and forms a stable mixed flow state with the air under the principle of gas-solid two-phase flow, and continues to be transported rapidly along the pipeline to the discharge end. In this process, the characteristics of the material and the structural parameters of the pipeline will have an important impact on the transportation efficiency and stability. When the mixed flow of materials reaches the unloading position, the gas-solid separation device starts to work. The common cyclone separator uses centrifugal force to make the material particles move towards the wall of the device in the high-speed rotating air flow and settle, while the filter separator uses the filter medium to accurately intercept the material particles and realize the efficient separation of materials and gases. The separated materials fall into the designated container to complete the unloading process. The purified gas is discharged to the outside environment.

Product features

1. Outstanding conveying efficiency: The continuous vacuum feeder, with its uninterrupted material conveying mode, significantly enhances production efficiency. It perfectly adapts to large-scale production scenarios, ensuring a stable and timely material supply on continuously operating production lines, effectively avoiding production stagnation caused by shortages and promoting the efficient operation of the production rhythm.

2. Prominent environmental performance: The fully enclosed conveying pipeline design fundamentally eliminates the problems of material leakage and dust. This not only strictly follows environmental protection regulations but also creates a healthy and clean working space for operators, effectively reducing the risk of pollution in the production environment and enterprises achieve green production.

3. Material quality assurance: During the conveying process, the contact between the material and the outside air is minimized. For materials that are highly to oxidation and moisture absorption, such as pharmaceuticals and food additives, this can maintain their original quality and characteristics to the greatest extent, effectively reducing material loss and ensuring stability of product quality.

4. Highly automated control: Equipped with advanced control systems, the device supports remote operation and real-time status monitoring. Operators can accurately set parameters such as material conveying volume and conveying speed according to actual production needs, and it can also be easily linked with other production equipment to achieve a fully automated production process significantly reducing labor dependence and improving the stability and reliability of production.

5. Flexible layout advantages: The conveying pipeline can be personalized according to the complex and changeable site, whether it is horizontal laying, vertical lifting, or inclined conveying, it can easily cope with it, and it can also skillfully avoid various obstacles, perfectly the spatial structure and process flow of different workshops, and fully tapping the potential of space utilization.

6. Wide range of applicability: Whether it is powdery granular, or片状 materials, the continuous vacuum feeder can properly convey them. This makes it widely used in chemical, food, pharmaceutical, plastic, building materials other industries, showing strong versatility and meeting the diverse material conveying needs of different industries.

7. Low maintenance cost: The equipment structure is relatively simple, the number of components is limited, the operation status is stable, and the probability of failure is low. The daily maintenance work mainly focuses on the vacuum pump and the pipeline connection parts which are simple and easy to operate, and the maintenance cost is controllable, effectively shortening the equipment downtime and extending the overall service life of the equipment.

8. Reliable safety performance: The use of vacuum conveying methods avoids direct contact between mechanical transmission parts and materials, significantly reducing the safety hazards caused by mechanical friction and collisions. At same time, the equipment is equipped with complete safety protection devices, such as overload protection, vacuum degree monitoring and alarm system, etc., to comprehensively guard the of equipment operation.
