Problems solved by technology
[0003] At present, in the production process, there is no condition monitoring method for the temperature control system. Only when the temperature does not meet the process requirements, the temperature control system is repaired and maintained. This method of after-the-fact maintenance cannot strictly guarantee the temperature of the tobacco leaves. stability

Embodiment Construction
[0044] The present invention is described in detail below in conjunction with accompanying drawing:
[0045] A method for preventing abnormal temperature of tobacco leaves in a blade feeder, comprising the following contents:
[0046] Step 1. Use the PLC controller to collect data on steam flow, steam pressure, heat exchange steam valve status, atomizing steam valve status, regulating steam valve opening and atomizing nozzle steam pressure.
[0047] Step 2. Compare the collected steam pressure with the process requirements. If the steam pressure is lower than the process requirements, 0.5 points will be deducted for every 1% lower than 10%. . The overall reduction of vapor pressure is;
[0048] Fp = P - Pb Pb * 1 % * 0.5 + IF ( P ...

The invention discloses a tobacco leaf temperature anomaly prevention method for leaf feeders. The method includes: 1, acquiring data by a PLC (programmable logic controller); 2, comparing acquired steam pressure to a process requirement; if the steam pressure does not reaches the process requirement, and sending out an alarm message; 3, comparing acquired adjusting steam flow to a theoretical flow; if the steam flow is lower than the standard flow, sending out an alarm message; 4, after one batch of production, counting average opening of adjusting valves; comparing the average opening to an ideal area; if opening distribution exceeds the ideal area, and sending out an alarm message; 5, calculating a total score; if deduction exceeds a set score; sending out an alarm message. The method has the advantages that the status of a temperature control system is monitored in real time, the whole temperature control system is assessed by means of feature curves of key parts and a health assessment method, and potential equipment hazards can be found.
Description
technical field [0001] The invention specifically relates to a method for preventing abnormal temperature of tobacco leaves in a blade feeder. Background technique [0002] As the key equipment for cigarette production, the leaf feeder is responsible for uniformly applying the feed liquid to the tobacco leaves according to the formula requirements, and making the tobacco leaves reach the temperature required by the process to promote the absorption of the feed liquid. As the main index of the feeder, the temperature of the tobacco leaf has a great influence on the smoking taste of the cigarette. [0003] At present, in the production process, there is no condition monitoring method for the temperature control system. Only when the temperature does not meet the process requirements, the temperature control system is repaired and maintained. This method of after-the-fact maintenance cannot strictly guarantee the temperature of the tobacco leaves. stability. Contents of the ...
