Changzhou one-step drying introduced closed-circuit circulation spray dryer using inert gas drying medium

In Changzhou, one-step drying introduces advanced foreign technologies and improves old production processes. Recently, the company launched a closed-cycle spray dryer system that operates in a closed environment. The drying medium is inert gas, generally N2, and the materials suitable for organic solvents are dried. The poisonous material or the drying of the oxidized material during the drying process.
The system uses inert gas as circulating gas to protect the dried material. The circulating gas undergoes the process of carrying moisture and dehumidification. The medium can be reused. The nitrogen is heated by the heater and enters the drying tower. The liquid material is conveyed by the screw pump. At the centrifugal nozzle, the liquid is atomized into droplets by a high-speed circulating atomizer, the heat and mass exchange process is completed in the drying tower, the dried powder material is discharged from the bottom of the tower, and the evaporated organic solvent gas is negative pressure in the fan. Under pressure, the dust contained in the gas is condensed by the cyclone separator and the spray tower, and the saturated organic solvent gas is condensed into a liquid by the condenser to discharge the condenser. After the continuous heating of the non-condensable gas medium, the dry carrier is used as a drying carrier in the system. recycle. The conventional ordinary centrifugal spray drying achieves the purpose of dehumidification by continuous delivery and exhaust. This is a clear difference between the explosion-proof type centrifugal spray drying equipment and ordinary centrifugal spray drying equipment. The drying medium in the drying system is N2. The internal pressure is positive and maintains a positive pressure value. If the internal pressure drops, the pressure transmitter automatically controls the N2 intake to ensure system pressure balance.

This kind of End Cover Pressing Machine can meet the requirement of different end cover and armature dimension. It makes the whole pressing process far more iconvinient than by manual. This machine can also be connected to Armature Production Line to meet the mass production requirement.


It can greatly reduce the larbor forces. Firstly, operator needs to load the end cover and the armature core to the required tooling position. Then press the start button. Machine will do the pressing process. The process can be shown as below picture. Two seperate parts will be combined into one part.

We have two types of end cover inserting machine, the automatic type and the semi-auto type. The automatic Shaft Pressing Machine is equipped with touch screen, all the parameter can be set in the touch screen. It is accurate. This automatic end cover inserting machine can be connected with a mechanical conveyor to acheive the mass production. The semi-auto type one is far more simple than the automatic one, compared with the operation step. And the price is also more favorable.
