CHRIS丨The working principle and daily maintenance of pneumatic conveying equipment

  • Categories:News Center

(Summary description)The working principle of the pneumatic conveying equipment is to use the positive pressure air flow generated by the Roots blower as the conveying power to transport the material continuously supplied by the rotary feeder from the lower hopper to the subsequent storage bin. The storage bin is equipped with a dust removal device on the top of the bin to separate the material and gas conveyed into the storage bin. The whole system consists of Roots blower, manual flap valve, rotary feeding device, venturi injection device, conveying pipeline, pipeline branch valve, storage bin, bin top dust removal device, electrical control system and related auxiliary settings. . When the system is working, start the Roots blower, which generates a high-pressure columnar air flow, which passes through the venturi jet pump, and generates a negative pressure inside, so that the material supplied by the rotary feeder is sucked into the Venturi jet in time. mouth. The material is transported to the storage bin through the conveying pipeline. Then, the top dust collector installed on the top of the storage silo separates the material from the conveying airflow, and the remaining airflow is discharged to the outside in time to avoid too much dust on site.   Equipment maintenance: 1. Roots blower: After the Roots blower is used for a certain period of time, the corresponding lubricating oil should be added to the bearing in time, and the gear oil should be replaced in time after a period of use. 2. Pipeline shunt valve: when it is working, the power generated by the actuating cylinder causes the ball valve inside to switch the direction and complete the corresponding pipeline reversing function. When the reversing function, the corresponding conveying process must be stopped to avoid the conveying process in progress. In this way, the reversing valve is subjected to a relatively large impact, and it is easy to be stuck, and the damage to the cylinder is relatively large. If the action of the cylinder fails, check whether the corresponding air path is unobstructed and whether the air pressure meets the corresponding working requirements. 3. Rotary feeder: when it is working, the power generated by the motor drives the inner supply blade to rotate, and the upper material is continuously conveyed to the lower part. The gap between the blade and the shell is ≤0.1mm; the sealing performance is excellent, and it is made of wear-resistant materials. If the wear-resistant sheet has been worn for a long time, which affects its work, the original wear-resistant sheet should be removed and a new one should be replaced, so that it can always maintain a pneumatic seal when working. 4. The connection of the conveying pipeline is firm. After the installation of the whole conveying pipeline, the corresponding pressure test should be done to confirm that there is no air leakage or air leakage at the connection. 5. The manual slide valve should keep its movements flexible, regularly disassemble the upper cover, add lubricating oil to the corresponding screw rod, remove the accumulation on the screw rod, and make it rotate smoothly. 6. Dust collector on the warehouse roof: after long-term work, the dust bag should be replaced in time to prevent the effect of the work effect after the gap of the dust bag is blocked.
