The operation steps of the small bag dust-free feeding station can be divided into the following processes, which are explained in combination with the equipment structure and industry application characteristics:
1、 Preparation before operation
1. Equipment inspection
Confirm that the main body of the feeding station (including feeding hopper, dust collector, vibrating screen) and connecting pipelines (such as soft connections and flanges) are not damaged, and that the filter element is installed in place and has good sealing.
Check if the air source pressure (0.5-0.7MPa) and electrical circuit (such as 24VDC pulse solenoid valve) are normal.
2. Environmental preparation
Ensure the ventilation system in the feeding area operates with a relative humidity of ≤ 60% and a temperature of 5-40 ℃.
Operators are required to wear protective equipment such as dust masks and goggles.
2、 Feeding operation process
1. Material deployment
Place the small bag material on the feeding station bracket, push it into the grid, and cut open the vertical opening of the bag.
Pour and shake the material bag to make the material completely fall into the feeding hopper, and the vibrating screen automatically screens out large impurities.
2. Dust control
The built-in dust removal fan starts and collects dust through an efficient filter (such as a polyester fiber coated filter element) to clean the exhaust gas.
The blowback system automatically cleans the filter element according to the set cycle (5-10 seconds/time), and the dust falls back into the hopper.
3. Material transportation
The screened material is transferred to downstream equipment in a sealed manner through a bottom conveying pipeline (such as a pneumatic conveying system).
3、 Post operation maintenance
1. Equipment cleaning
Turn off the power, clean the residual materials in the feeding hopper and vibrating screen, and check the blockage of the filter element.
2. Record and Inspection
Record the feeding amount and equipment operation status, and regularly replace the filter element (recommended every 3-6 months).
4、 Precautions
1. When feeding, it is necessary to avoid material accumulation that may cause overload of the vibrating screen.
2. Explosive and flammable environments require the use of explosion-proof tools and ensure good grounding.
This process achieves efficient and dust-free feeding through automated design (such as PLC control) and enclosed structure, and is suitable for industries such as food and pharmaceuticals.
