Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology for vacuum ovens, and in particular to a vacuum sealing structure for a temperature measurement flange of a vacuum oven. Background Technology

[0002] In battery baking equipment, traditional connection methods for detecting and controlling the internal temperature include surface-mounted indirect temperature measurement: thermocouples or thin-film temperature sensors are attached to the outer wall of the cavity, and the internal temperature is indirectly measured through heat conduction via the cavity's metal wall. The difference between the outer wall temperature and the actual internal temperature is then calibrated experimentally, and a compensation algorithm is added to the temperature control system. The advantage of this method is that it does not damage the cavity structure and has no risk of leakage. The disadvantages are slow response speed (thermal hysteresis) and accuracy dependent on calibration. Therefore, this patent addresses the problems of temperature measurement, temperature control, and sealing of heating components in intelligent ovens under vacuum conditions. Utility Model Content

The temperature sensor 10 is fixed in the middle of the side bracket 11. A pin 12 is provided on one side of the temperature sensor 10.

[0030] The vacuum sealing structure of the temperature measuring flange of the vacuum oven is provided with a 304 central support 9 between the sealing cavity flange 1 and the base 8 to achieve the effect of sealing connection.

[0031] Working principle:

[0032] This invention integrates the temperature sensor 10 of the heating element inside the cavity into the flange blind plate 4, enabling real-time temperature monitoring and control in closed pipelines or equipment. The high-reliability connection of the aviation plug 5 ensures stable temperature signal transmission, making it suitable for complex high-temperature and high-pressure environments in industrial settings. This invention primarily designs a method and structure for sealing the temperature-sensing flange externally to the oven cavity.

[0033] The principle is as follows: the temperature sensor 10 of the heating component inside the cavity is connected to the aviation plug 5 of the temperature measuring flange through the cavity wire groove. By utilizing the high reliability of the aviation plug 5 and the strong sealing performance of the flange blind plate 4, the intelligent oven can monitor and control the temperature in real time under high temperature and vacuum conditions and ensure good vacuum pressure in the cavity.

[0035] The relationship between the various parts is as follows: Except for the baking plug flange blind plate 4, which is made of 304 stainless steel, all other components are standard parts. The temperature sensor 10 of the heating element is connected to the aviation plug 5. The aviation plug 5 is fastened to the baking plug flange blind plate 4 with screws. A 304 center bracket 9 is used to seal the temperature sensing flange and the sealing cavity flange 1. High-vacuum caliper screws lock the two flanges together to achieve a sealing effect. The temperature sensing flange is designed for high-temperature and high-pressure operating environments, ultimately achieving stable transmission of the temperature signal from the aviation plug 5, real-time monitoring and temperature control, and effective sealing. The use of the blind plate 4 and aviation plug 5 allows for quick disassembly and assembly, facilitating calibration, maintenance, or replacement, reducing downtime, and greatly improving the oven's operating efficiency.
