ZKS Vacuum Feeding Machine: Structure, Principle, and Usage Guide
Date: 2025-10-11Read: 6
ZKS vacuum feeder is a commonly used equipment for conveying powder and granular materials, suitable for industries such as pharmaceuticals, food, and chemicals. It can be matched with V-type mixers, double cone mixers, and other equipment to complete automatic feeding, and the operation process meets GMP requirements. The following provides an explanation of the device structure, working principle, and usage precautions.
1、 Equipment structure and applicable scenarios
（1） Core components
The equipment consists of a mobile rack, vacuum pump, powder recycling cylinder, primary filter purifier, suction pipe, and electrical control box. All components are integrated on a mobile rack, which is easy to move and can adapt to the layout requirements of different workshops. The material of the components that come into contact with the material meets industry cleanliness standards and supports quick disassembly and installation.
（2） Scope and Limitations of Application
It can transport granular materials such as raw material pharmaceutical powder, chemical powder, capsules, and small food particles, and is widely used in automatic conveying scenarios in industries such as plastics, rubber, and pharmaceuticals. But it is not suitable for conveying materials that are too damp, viscous, or heavy, to avoid equipment blockage or damage.
2、 Working principle
The equipment uses a vortex air pump to draw air, creating a vacuum state in the suction nozzle and system. The powder particles are sucked into the suction nozzle with air, forming a material airflow and reaching the hopper through the suction tube. Complete the separation of gas and material in the hopper, and the separated material falls into the receiving equipment. When the silo is filled with materials, the controller automatically cuts off the power, the equipment stops working, and compressed air passes through the pulse blowback valve to clean the filter. After receiving the feeding signal, the equipment restarts and completes the material conveying cycle.
3、 Precautions for use
（1） Preparation before startup
•Equipment and gas source inspection: Confirm that the equipment is placed firmly, the rack is not shaking, and the connecting bolts of each component are tightened. After connecting the air source, adjust the filter pressure reducing knob to keep the pressure at 0.55-0.6MPa. If there is water or foreign matter in the filter pressure reducing cup, it needs to be cleaned before use. Check if the tracheal connection is secure to prevent tracheal detachment during operation.
•Component and raw material inspection: Check the cleanliness and sealing of the pneumatic door circular plate, and confirm that the screws are tightened. Check that the filter is not damaged and the suction tube is not blocked or damaged. Raw materials need to be free of lumps and impurities to ensure appropriate dryness and avoid affecting conveying efficiency.
•Electrical system inspection: Before connecting the power supply to the control cabinet, confirm that the power cord is intact, the grounding is reliable, and the emergency stop button is in normal condition.
（2） Running operation
•Start and parameter confirmation: Turn on the emergency stop button, set the switch to "automatic" mode, start the vacuum pump, enter the operation interface through the touch screen, and confirm that the system parameters have been set as required.
•Operation monitoring: Observe the material conveying status. If the conveying speed slows down or is interrupted, check whether the suction pipe is blocked and whether the air source pressure is normal. Pay attention to the sound of equipment operation. If there is any abnormal noise, immediately press the emergency stop button to stop the machine for troubleshooting.
•Safety regulations: Operators should avoid approaching high-speed moving components and tracheal interfaces. When sudden situations such as tracheal detachment occur, immediately turn off the main gas source. Do not disassemble the hopper or filter while the device is running.
（3） Post shutdown processing
•Standardized shutdown: First, turn off the gas source, press the operation button to release the remaining gas, and then turn off the power supply of the control cabinet.
•Cleaning and tidying up: Open the quick release clamp, remove the filter and blow off the surface material with compressed air. It is necessary to do so every week or when changing varietiesclean. Clean the residual materials on the inner walls of the hopper and suction tube, and wipe the dust on the surface of the equipment.
•Component reset: After cleaning, install the components in the order from bottom to top, ensuring that the sealing ring is in place and the connection is well sealed to prevent air leakage.
