1、 Introduction to Multi functional Extraction Tank Equipment
1.1 This unit is designed for the combined application of extraction and concentration, and can be used in universities, research institutions, hospitals, etc. for the extraction of new drugs, determination of new process technology parameters, intermediate experiments, development of new varieties, extraction of valuable medicinal materials, recovery of volatile oils, and concentration of medicinal liquids. 1.2 This unit has complete functions and can obtain full system vacuum, which can meet the extraction of volatile oil, water extraction, alcohol extraction, animal visceral extraction, staged extraction, and hot (temperature) reflux extraction; The extraction solution can be concentrated, the paste can be collected, and the organic solvent can be recovered; This equipment adopts a special structure in the concentration system to achieve the maximum final density of the product and ensure smooth discharge; Has a high degree of automation control and accurate and reliable data collection; Adopting PLC control system and touch screen user-friendly interface. Various program operation parameters are programmed to monitor the operating status of the entire unit online and automatically control the equipment. The operation parameters can be modified, stored, and printed according to the actual situation.
1.3 Locking and Opening of Slag Gate: Closing the Door Locking: Press the SB3 button once, the solenoid valve QG1 is powered on, the cylinder QGA moves to close the door, and wait for the power off switch SQ1 to send a signal; Press the SB4 button, the solenoid valve QG3 is powered on, the cylinder QGB is locked, the limit switch SQ2 is activated, and the door is successfully closed and locked; After a delay, the solenoid valves QG1 and QG3 lost power. Close the solenoid valve and use it for thousand pin locking. The main components include a multifunctional extraction tank, a single effect concentrator, a liquid storage tank (one tank can be used for multiple purposes: it can also be used for ethanol blending tanks and alcohol settling tanks), an explosion-proof centrifugal pump, an explosion-proof water circulation vacuum pump, and a steam generator.
1.4 [Main specifications, technical parameters and dimensions] Model: NS-0.1 Extraction tank capacity: 100L Operating pressure inside the tank (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 discharge door diameter (mm): 400 External dimensions (length x width x height): 2300 × 650 × 2400 II. Operating procedures 2.1 [Unit installation and commissioning]
2.1.1 The integrated extraction and concentration system of this equipment must be installed strictly according to the system process and cannot be changed arbitrarily.
2.1.2 All external pipe openings must match the equipment pipe openings to prevent blind spots from affecting system circulation.
2.1.3 The installation of steam pipelines should have three-level effective pressure reduction within 2 meters of the equipment, and a pressure gauge and safety valve should be installed at the inlet with a pressure range of 0.315 MPa.
When testing the system, first check whether the thermal steam trap is normal, and open the bypass valve next to the steam trap before steam enters to prevent rust and scale in the steam pipe from passing through the jacket and blocking the steam trap with condensed water.
During debugging, it is strictly prohibited to extract empty cans from the tank for heating. Before vacuum operation, the pipeline and seal should be tested with filtered compressed air at 0.05-0.09Mpa to ensure that the entire system is leak free before testing.
After the system test is completed, refer to the instruction manual for the operation method.
2.2 [Unit Operation Procedure]
2.2.1 Locking and Opening of Slag Gate: First, press the SB4 button to activate solenoid valve QG4 and activate cylinder QGB. Then, press the SB3 button to activate solenoid valve QG2 and open the door; After a further delay, solenoid valves QG4 and QG2 lose power. Electromagnetic valves QG4 and QG3 are interlocked, while QG1 and QG2 are interlocked.
2.2.2 Whole system vacuum: Open pneumatic valves C3, C16, C18, C25, C29, C30, M32, and use vacuum pump M1 to evacuate the system. Adjust the vacuum degree of the single effect concentrator through valve C31, and extract the cold and warm water from the condenser through pump M1.
