Brief delivery process/user self-installation and debugging process

1. Choose a relatively independent space to install the equipment.
Basic requirements: no sun and rain, cool and ventilated, ventilation can be natural ventilation or explosion-proof exhaust mechanism; no paint, solvents and other flammable and explosive materials are piled within 10 meters around the equipment, and any fire operation and non-operating personnel activities are strictly prohibited around; if you need more installation environment and facility requirements, please contact the manufacturer or sales staff.
2. Ask the electrician to connect the power supply.
Three live wires, one neutral wire, and one ground wire.
Note: Generally, the default black is the neutral wire, the two-color is the ground wire, or the wiring is according to the equipment logo.
Note: Do not connect wrongly, which may burn out the power supply, contactor, etc.; (Note: 20L equipment is 220V power supply); After connecting the power supply, check the forward and reverse rotation of the motor. If it is reversed, adjust any two live wires.
The correct exhaust direction of the motor is as follows (blowing directly toward the condenser; please note that it is blowing directly toward the condenser): (20L equipment uses a 220V power supply, so there is no need to consider the forward and reverse rotation of the motor;)
——Water-cooled equipment does not need to be considered;

——If the motor reverses, the heat dissipation effect will be poor! Some equipment has phase sequence protection devices; some equipment has solvent outlet over-temperature protection, which will alarm. Please refer to the actual configuration and inspection confirmation; 3. If it is equipped with a "vacuum negative pressure storage all-in-one machine (vacuum pump; hereinafter referred to as: all-in-one machine)", it must be connected to 4-7 kg of compressed air. Please use an 8mm outer diameter air pipe and connect the main machine solvent outlet and the all-in-one machine solvent inlet with a solvent pipeline.
Please note: Make sure that all connections are well sealed! After the recycling machine host is turned on, the all-in-one machine turns on the "negative pressure" operation, and the steam/cooled liquid generated in the host will be automatically sucked into the all-in-one machine (storage tank).
After the recycling is completed, (all-in-one machine) closes the feed valve, opens the discharge valve, and discharges the material outward according to the boost operation.
4. Safety valve. Due to transportation reasons, some equipment is not installed. Just install it (the exhaust port is on the back of the equipment); Solvent outlet pipe. Just install it;
5. While doing the above work, please prepare the corresponding amount of waste solvent. For example, for TE-60 equipment, prepare about 60 liters (common paint buckets * 3 buckets); at the same time, prepare 2-3 clean buckets for receiving clean solvent;
6. Adding materials. According to the equipment configuration, you can add materials manually or by pump. Generally speaking, small equipment can be added manually. Large equipment is generally equipped with a diaphragm pump, which can be started to feed.

If you use a recycling bag, it is equipped with a clamp. In order to prevent the bag from covering the steam outlet, you can "cut a hole" in the bag at the corresponding position, pass the steam pipe through it, and fix it with a clamp.

After adding materials and cleaning slag, keep the "flange surface" clean! If there is waste solvent, paint, residue and other contamination on the flange surface, you can use a rag dipped in solvent to clean it. Be sure to keep it clean!

Then, put the lid on the barrel, handle it with care, and tighten the screws evenly diagonally. Note: It only needs to be tight by hand, or tighten it appropriately with a screwdriver.

6. Prepare to start the machine. Setting the temperature and time are the key points in the entire delivery and commissioning process. Note: If the manufacturer has been informed of the solvent components that need to be recovered before the equipment leaves the factory, the manufacturer can set the parameters before leaving the factory, and this operation is not required.

Setting temperature and time: Generally, it is set according to the solvent composition and equipment capacity. The basic principle is: the set heating temperature is 40℃ higher than the boiling point of the solvent composition, and the set heating time refers to the average time corresponding to each equipment in the "Instructions". The actual time is related to the solvent composition and concentration. For example, if we want to recycle xylene, assuming that there is only this component with a boiling point of 137, then we can set the heating temperature to 177 (not absolute, a few degrees above or below will basically not affect the overall effect). The recovery time of 60 liters of toluene solvent is generally 3-3.5 hours; that is, set it to one section, temperature SP1:177, time T-1:210 minutes. How to set the temperature and time, please see the attached video 1 "How to set the temperature" (video is not available, please refer to the instructions); for another example: if we want to recycle ethyl ester and xylene, the boiling points are 77 and 137 respectively. Assuming that the two components account for 50% each, if we directly set it to the highest heating temperature, 177, it is very likely that "foaming" will occur (the solvent boils violently and flows directly from the steam pipe). How to set it? Two sections can be set. The first section SP1: 120℃ (about 77+40), run for 100 minutes, recover the low boiling point first, and then the liquid level drops. After the first period of time, it automatically transitions to the second section, such as 177 degrees (137+40), and then runs again, such as 110 minutes; there is a general principle for setting temperature and time: whether it is set to 1 section or 2 sections, when the liquid is discharged, the discharged solvent should be at room temperature, or close to room temperature. In addition, 95% of the solvent can be recovered in the end, that is, the final residue is generally solid or semi-solid; some residues are thin when they are still hot in the pot, but dry after cooling;

Note: For safety reasons, it is not recommended to steam too dry, and do not force steaming too dry! ! After running 1-2 processes completely, determine the final operating parameters based on the liquid discharge and residue status. Generally, the solvent composition remains unchanged, and the set temperature and time can remain unchanged. When the temperature and time are set properly, save and exit.
7. Turn on the machine. Turn on the switch and connect the power; press the start (run) key (the second key from the left below the display) for about 1 second. The condensing fan/water cooling starts, and the running light flashes, indicating that heating has begun.

8. During the recovery process, pay attention to the rise of oil temperature and steam temperature, pay attention to the liquid output (generally speaking, the liquid output is at room temperature. If it exceeds room temperature, the oil temperature may be set too high), and pay attention to the state of the remaining residue (generally speaking, for a 60-liter machine, conventional solvents can be recovered in 3-3.5 hours, and the remaining residue is solid or semi-solid. If there is a small amount of liquid left, the oil temperature or heating time can be adjusted as appropriate. If there is a lot of liquid left, there may be a high-boiling point solvent or other abnormal conditions). Note: If the user debugs the equipment by himself, it is recommended to keep records in the 1st and 2nd processes, and feedback the set heating temperature, actual oil temperature, steam temperature and liquid output status to the technician every 30/15 minutes to ensure that the set parameters best meet the actual needs.
9. After the settings are completed, save and exit, and lock the corresponding doors and windows.
10. Handover of manual and other materials, signature of delivery order, etc.
11. Daily maintenance (attached with separate document for detailed description)
(1) Regular inspection and calibration of safety valves;
(2) Regular dredging of internal steam pipelines and liquid outlet pipelines;
(3) Cleaning of condenser surface to ensure heat dissipation effect;
(4) Regular replacement of heat transfer oil;
12. For more details, please refer to the manual or contact sales/after-sales personnel;

13. Supplementary instructions for continuous equipment settings:
Prerequisites:
1. The solvent composition is relatively simple, and it is not recommended to be used to recover solvents with complex compositions such as low boiling point and high boiling point;
2. The solid content of the solvent is relatively low; Take a 150-liter continuous equipment, such as the recovery of ethyl ester, as an example; the boiling point of ethyl ester is about 80, so set the heating temperature to 120 degrees (+40 degrees); it generally takes 4.5 hours to recover 150 liters of ethyl ester; so now it is planned to let the equipment work continuously for 10 hours, how to set it?

You only need to set the heating time to 600 minutes and the feeding time to 600-4.5*60=330 minutes. That is to say, within 330 minutes, when the system recognizes that the liquid level has dropped, it will automatically add material to the barrel until the end of 330 minutes (feeding time); finally, the remaining 150 liters of solvent in the barrel will be recovered in the remaining 270 minutes and the machine will be shut down. For more setting details, please consult the technicians.
