The independently developed PID control system is currently one of the most advanced AI temperature control systems, with humanized fully automatic digital display control. Accurate control of heating temperature, recovery of multiple solvents can be set with multi program control, and fully automatic production equipment does not require dedicated personnel to monitor. The heating temperature can be set in multiple stages, allowing solvents with different boiling points to be sequentially distilled from low and high temperatures in batches. Avoid adding to the highest temperature at the beginning, which may cause low boiling solvent to excessively boil and foam, resulting in dirty solvent flowing into the pipeline and causing blockage.
Specially designed explosion-proof operating mechanism, allowing the machine to set safety parameters without opening the operating box, suitable for operation in explosion-proof environments!
The stainless steel chassis shell is easy to clean for dirt and oil stains, and can be gently wiped clean. Its appearance can remain brand new for a long time.
● Timed shutdown function: pre-set the recycling time of the machine. When the machine reaches the preset running time, the equipment will stop heating. When the fan continues to run for about 20 minutes, the equipment will automatically stop. This function prevents residual solvent vapor from flowing out of the pipeline when all power is turned off in the barrel slot, causing safety hazards
Temperature control alarm device:
1: The instrument comes with an alarm device. Equipped with over temperature protection, over pressure protection, simultaneous timed protection shutdown, constant temperature protection shutdown, power outage protection, heating area protection, sensing open circuit protection (2 sets), and sensing positive and negative pole protection (2 sets).
2: Independent mechanical temperature control alarm device. After the alarm is activated, the heating will immediately stop, but the fan will continue to dissipate heat to prevent the solvent vapor in the tank from being unable to dissipate heat and creating danger.
● Stainless steel recycling bucket, corrosion-resistant; Double layered structure for indirect heating and safe heating.
Stable and durable performance, simple maintenance, low consumables, and ultra-low maintenance costs.
3. It also has ultra-high temperature and timeout protection.
● Ultra high voltage protection. Install the set pressure safety relief valve on the lid of the recycling bucket. When the steam pressure inside the bucket reaches 0.08Mpa, the safety valve will automatically open for pressure relief.
Set the recycling time to automatically shut down.
Automatically shut down after solvent recovery.
Specially customized equipment that meets the needs of various industries, with precise temperature control and safe and durable materials.

Machine operation steps
1. Preparation for recycling work:
Before recycling, users should prepare for the recycling process by preparing waste solvents, checking the power supply, gas source, pipelines, valves, and other components to ensure they are functioning properly. After confirming that everything is normal, proceed with the following tasks.
2. Start and feeding program:
Start the automatic feeding pump air source, execute the feeding program, and the waste solvent is pumped through the explosion-proof pneumatic diaphragm pump. It passes through the feeding valve and enters the solvent recovery tank, where it is automatically fed to the full liquid level (250L). At this time, the explosion-proof pneumatic diaphragm pump manually stops working and feeding is stopped.
3. Recycling procedure:
After the feeding is completed, turn on the machine power and start the machine program. The machine will automatically enter the recycling program, and use the program controller to recycle the waste solvent according to the preset time and temperature.
4. Discharge procedure:
After recycling, the clean solvent is stored in a vacuum pressure reducing device, and the clean solvent is quantitatively transported outward using an explosion-proof pneumatic diaphragm pump.
5. Manual slag discharge:
After the recycling machine automatically shuts down, open the manual slag discharge valve, and the residue is discharged from the recycling bucket into the prepared container. After the work is completed, we can start the next cycle of recycling work
