The fully automatic vacuum feeder is powered by compressed air and uses vacuum suction to transport particles and powdery materials without the need for power supply.The conveying process is carried out in a completely enclosed environment, without any dust leakage. Made of stainless steel material, it is acid and alkali resistant, corrosion-resistant, and has mirror polished surfaces inside and outside the equipment. It has low energy consumption, high efficiency, and low noise. The modular design can be combined according to the requirements of the working conditions, and the external design is smooth for easy inspection, cleaning, and disinfection.

When the vacuum feeder is working, the vortex air pump is used to extract air, so that the inlet of the suction nozzle and the entire system are in a certain negative pressure state. The powder particles are sucked into the feeding nozzle along with the external air, forming a material airflow, which passes through the suction pipe to reach the hopper, where gas and material are separated.The separated materials enter the receiving equipment.The feeding and discharging are achieved by continuously opening and closing the pneumatic directional valve, which is controlled by the control center.

The fully automatic vacuum feeding machine cannot suction the material, and I believe many old users have encountered this problem. When encountering this problem, the first step is to find the cause of the problem in order to solve it accordingly:

1. Non feeding caused by blockage of the filtering device

Solution reference: Remove the filter element, blow it clean with compressed air, and place it in an ultrasonic cleaner for 30 minutes with a standard load.

2. Habitual non feeding leading to material blockage in the filtering device

Solution reference: The key reason is that the total filtering area and precision of the filtering device are not sufficient. In this case, a filtering device with good characteristics should be replaced, which should have high-quality characteristics such as easy to blow off smoke and dust, moisture and oil resistance, stronger total filtering area, and stronger filtering precision, such as polyester coated sub membrane filter element and titanium sintered filter element.

3. Software difficulties in the anti blowing system

Solution reference: Single pulse anti blowing system software with better processing characteristics should be produced.For detailed key points, please feel free to provide more information.

4. Difficulties in pipeline connection

Solution reference: Check if the pipeline, intermediate pipe clamp of the silo, and hard connection are tightened, which may cause system software leakage and result in insufficient vacuum value, endangering feeding.

5. Slow opening of gate valve caused by insufficient cylinder pressure

Solution reference: Use to increase the air pressure

6. Excessive residual material in the pipeline

Solution reference: In long and high transportation loads, there may be excessive residual materials in the pipeline, and a system software for removing residual materials in the pipeline should be designed.
