Description

Technical Field

[0001] The utility model relates to a temperature monitoring system, in particular to a temperature monitoring system for a copper rod rolling vertical furnace burner. Background Art

[0002] In the copper rod rolling process, the vertical furnace is a key production equipment. Its working status directly affects the quality of the final product and the continuity of production. In order to ensure the stability and safety of the production process, real-time monitoring of the temperature of the vertical furnace burner is particularly important. This not only ensures that product quality meets the standards, but also effectively prevents safety accidents caused by abnormal temperatures.

[0003] A typical temperature monitoring system primarily consists of the following components: a PLC controller (a programmable logic controller, responsible for processing data from field devices and issuing control commands based on preset logic); an HMI screen (a human-machine interface, through which operators can view various parameters in the production process and make necessary adjustments); and temperature probes (used to directly measure temperature changes in the shaft furnace burner area, converting the physical signals into electrical signals for transmission to the PLC controller). While this monitoring system functions well in most cases, it also encounters some challenges in practice. For example, due to harsh environments or long-term use, individual temperature probes may experience aging damage or poor connector contact. While these issues can usually be promptly repaired without affecting overall operation, the real problem lies in the event of a PLC temperature module failure. Even if the problem has been resolved, the module still needs to be initialized and reset to resume normal operation. Due to system design limitations, the only reset method currently is to power off and restart the PLC module. This method causes the entire PLC remote site to suspend operation, seriously affecting the normal production and efficiency of the shaft furnace. Utility Model Content

[0028] In the initial state, the closing plate 12 closes the right end of the butt-joint pipe 10 to prevent the hot gas in the vertical furnace burner 9 from leaking out of the butt-joint pipe 10;

[0029] When in use, first install the mounting base 4 in the designated position, then connect the temperature probe 3 to the external threaded tube 1502, so that the temperature probe 3 extends into the docking tube 10 through the external threaded tube 1502. When the nut 1501 contacts the contact plate 13, the nut 1501 will squeeze the contact plate 13 to move to the right, and the first spring 14 is compressed, so that the contact plate 13 drives the movable rod 11 and the closing plate 12 to move to the right, so that the closing plate 12 no longer closes the right end of the docking tube 10, so that the temperature probe 3 can extend into the vertical furnace burner 9 through the docking tube 10 to measure the temperature, thereby realizing temperature monitoring of the vertical furnace burner 9.
