Description

Technical Field

[0001] The utility model relates to the field of tire production and manufacturing, in particular to a device for quickly processing abnormal conditions of cross-gassing of tire vulcanization media. Background Art

[0002] During the semi-steel tire vulcanization process, the curing bladder and the shut-off valves for various media form a closed system. With multiple vulcanizers operating simultaneously, the shut-off valves can easily become loose, leading to cross-influx of high-pressure nitrogen, high-pressure steam, low-pressure steam, low-pressure nitrogen, vacuum pumping, nitrogen recovery, main exhaust, and steam condensate exhaust. Typically, high-pressure media cross-influxes into low-pressure media lines, causing abnormal internal pressure and resulting in defective products. This requires prompt and proper handling. However, in actual production, when such cross-influx anomalies occur, it's difficult to pinpoint the faulty machine. Typically, the voltage stabilization curve is checked machine by machine. This inspection requires numerous personnel and takes a long time to identify the faulty machine. Other machines must be stopped until the media returns to normal before normal production can resume, directly impacting vulcanization efficiency. Utility Model Content

[0021] The basic working principle of this utility model is briefly described as follows:

[0022] The vulcanization media pipelines within the vulcanization trench have set lower and upper pressure limits. For example, high-pressure steam (1.68-1.72) MPa, steam condensate exhaust (0-0.4) MPa, low-pressure steam (0.88-0.92) MPa, nitrogen recovery (0.2-0.3) MPa, high-pressure nitrogen (2.28-2.35) MPa, main exhaust (0-0.005) MPa, low-pressure nitrogen (0.15-0.18) MPa, and vacuum (-0.038--0.042) MPa. If the pressures of two or more media in a single trench exceed the upper or lower limits, the pressure information is transmitted to the DCS control system via a pressure transmitter, triggering an immediate alarm. Simultaneously, the red indicator light indicating the media abnormality in the center channel illuminates, and an audible and visual alarm sounds, alerting maintenance personnel and operators to the location of the vulcanization trench where the media abnormality is located. Then, through the MES production execution system, the voltage stabilization curve of the vulcanization machine in the abnormal vulcanization trench is queried. Based on the machines that simultaneously feed the medium during the medium abnormality period, the faulty machine is locked, and quick action is taken to restore normal vulcanization production.
