Product description

Dust-free feeding station is a equipment that can effectively reduce dust pollution in the process of material delivery, often used in new energy, pharmaceutical, chemical, food and other industries that are sensitive to dust pollution. When it is working, the negative pressure system and filter device are mainly used to maintain the environment in the station. The negative pressure system draws out the air through the exhaust fan, filters the dust particles through the filter device, and the purified air is returned to the station to form a circulation, so as to prevent the diffusion of dust. The filter device usually adopts high efficiency filter or bag filter, which can accurately capture dust and ensure that the feeding process is in a dust-free state. Its structure generally covers the feeding platform, discharge bin, dust removal system and vibrating screen and other components, the feeding platform is convenient for workers to place materials, discharge bin temporary storage of materials, dust removal system is responsible for dust collection and filtration, vibrating screen can intercept large materials and foreign bodies. The equipment is not only easy to operate and maintain, but also has the advantages of environmental protection, no pollution, high efficiency and energy saving, precise feeding, etc., which can significantly improve production efficiency, ensure product quality and employee health.

Working principle
The work of dust-free feeding station relies on negative pressure dust collection and gas-dust separation mechanism. When the bagged material is fed, the dust phenomenon appears, the fan operation causes the negative pressure inside the platform box, and the dust-containing gas is sucked in. Driven by the air flow, the dust flows to the filter element, the air can enter the bag through the filter element, and then discharged from the outlet by the fan, and the finer dust is intercepted and retained on the surface of the filter element, to achieve efficient separation of gas and dust.
As the feeding continues, the surface area of the filter element becomes more and more dust, and the resistance of the air flow through the filter element increases. In order to maintain the operation of the equipment in a reasonable resistance range, it is necessary to clean the ash regularly. The pulse injection system works on the filter element in turn according to the established procedure, and the compressed air is sprayed into the filter element through the jet nozzle, which promotes the rapid expansion of the filter element and generates a short reverse air flow in the fiber tissue, which is opposite to the gas flow direction during filtration, thus removing the ash outside the filter element. In addition, after the material is fed into the station, it will pass through the vibrating screen, which can effectively intercept loose materials and foreign bodies, ensuring that the granular material that meets the requirements of the specification enters the next process smoothly.
 
Features & Benefits

1. Environmental protection and dust-free: Through the principle of negative pressure dust collection and efficient dust removal system, such as the unique double filter element, pulsed vacuum reverse blowing/fan dust removal design structure, can effectively collect the dust generated during feeding, prevent dust flying, keep the workshop environment clean, meet the environmental requirements, and protect the health of workers.
   2. High efficiency and energy saving: The screening device adopts self-unloading design, high passing rate and large production capacity. Intelligent PLC control with patented design of backblowing system, can realize automatic operation, while ensuring production efficiency and reducing energy consumption.
   3. Accurate feeding: Some dust-free feeding stations are equipped with intelligent electronic metering instruments and high-precision sensors, which can monitor the weight of the material delivery in real time, accurately control the feeding speed and quantity, meet the requirements of accurate material delivery in the production process, and improve the stability of product quality.
   4. Easy operation: reasonable structure design, feeding platform height is usually humanized design, convenient for workers to unpack feeding operation. Some equipment is also equipped with gas spring steam opener and other devices, so that the door is easy to open. At the same time, the maintenance of the equipment is relatively simple, the use of modular design, quick disassembly structure, etc., easy to clean and repair, reduce the maintenance workload and downtime.
   5. Strong adaptability: can be applied to a variety of production processes, can be connected with screw conveyor, negative pressure vacuum feeder and other conveying equipment, suitable for different types, different particle size of powder, granular materials, as well as small bags or tons of bags packaging materials, widely used in biopharmaceutical, chemical, food, new materials, new energy and other industries.
   6. Safe and reliable: the closed structure is used to prevent dust leakage and reduce the risk of safety accidents such as dust explosion. Safety measures such as anti-delay design are adopted in the feeding place to ensure the safety of operators during the feeding process. The material of the equipment is strong and durable, such as 304/316L stainless steel, corrosion resistance, and can adapt to a variety of harsh working environments.
   7. Cost saving: effectively reduce the loss of materials in the feeding process and avoid material waste caused by dust flying. At the same time, the workload and cost of dust cleaning in the workshop are reduced, as well as the cost increase caused by equipment maintenance and product quality problems caused by dust pollution.
