Use and maintenance of multi-function extraction and concentration unit (1)

Posted on

I. Equipment introduction 1.1 [Machine use] This unit is a combined application of extraction and concentration. It can be used in colleges and universities, scientific research institutions, hospitals, etc. as new drug extraction, determination of technical parameters of new processes, intermediate tests, development of new varieties, and valuable medicines. Extraction, volatile oil recovery and liquid concentration. 1.2 [Functional Features] The unit is fully functional and can obtain full system vacuum, which can meet the extraction of volatile oil, water extraction, alcohol extraction, animal internal organs extraction, fractional extraction, hot (warm) reflux extraction; extract can be concentrated, can be collected The organic solvent can be recycled; the special structure of the equipment is adopted in the concentrating system, so that the final proportion of the product is achieved, and the discharge is smooth; the automatic control degree is high, the data collection is accurate and reliable; the PLC control system and the touch screen human machine are adopted. Friendly interface. It has various operating parameters of the program, monitors the running status of the whole unit online, and automatically controls the equipment. The operating parameters can be modified, stored and printed according to the actual situation.

1.3 [equipment composition] Locking and opening of the slag door: closing the door lock: press the SB3 button, the solenoid valve QG1 is energized, the cylinder QGA action makes the door close, wait until the power off switch SQ1 sends a signal; press the SB4 button, The solenoid valve QG3 is energized, the cylinder QGB is locked, the limit switch SQ2 is actuated, and the door is locked successfully; after a delay, the solenoid valves QG1 and QG3 are de-energized. Close the solenoid valve and use it for the 1000 pin lock. Including multi-function extraction tank, single-effect concentrator, liquid storage tank (one tank multi-purpose: can be used for ethanol blending tanks, alcohol tanks), explosion-proof centrifugal pumps, anti-storm water circulation vacuum pumps and steam generators and other major parts.

1.4 [Main specifications technical parameters and dimensions] Model: NS-0.1 extraction tank volume: 100L tank operating pressure (MPa): atmospheric pressure interlayer operating pressure (MPa): 0.3 feeding port diameter (mm): 150 heating area (m2) : 0.9 Condensation cooling area (m2): 2.0 slag door diameter (mm): 400 Dimensions (length × width × height): 2300 × 650 × 2400 Second, the operating procedures 2.1 [unit installation and commissioning]

2.1.1 The integrated extraction and concentration system of this equipment shall be installed in strict accordance with the system process during installation, and shall not be changed at will.

2.1.2 All external nozzles must be matched with the equipment nozzle to prevent the occurrence of dead angles affecting the system cycle.

2.1.3 Installation of steam line In the 2m of the equipment, there should be three levels of effective decompression and a pressure gauge installed at the inlet. The take-off pressure range of the safety valve is 0.315MPa.

2.1.4 When testing the system, first check whether the thermal steam trap is normal, and open the bypass valve on the side of the steam trap before the steam enters, in order to prevent the rust in the steam pipe from passing through the jacket, and block the steam trap with the condensed water. .

2.1.5 It is strictly forbidden to extract the empty tank heating in the tank during commissioning. Before the vacuum operation, the pipeline and seal test should be carried out with the filtered compressed air 0.05-0.09Mpa to ensure that the whole system can be tested without leakage.

2.1.6 After the system is finished, refer to the instruction manual for the operation method.

2.2 [unit operation procedure]

2.2.1 Locking and opening the slag door: first press the SB4 button, the solenoid valve QG4 is energized, the cylinder QGB is activated, then press the SB3 button, the solenoid valve QG2 is energized, open the door; The solenoid valves QG4 and QG2 are de-energized. The solenoid valve QG4 is interlocked with QG3, and QG1 and QG2 are interlocked.

2.2.2 Full system vacuum: Open the pneumatic valves C3, C16, C18, C25, C29, C30, M32, and vacuum the vacuum pump M1. The vacuum of the single-effect concentrator is adjusted by the valve C31, and the condenser cold and warm water is extracted by the pump M1.
