Description

Technical Field

[0001] This utility model relates to the field of thermocouple processing technology, and more specifically, to a thermocouple end vibrating device. Background Technology

[0002] Thermocouples are temperature sensors widely used in industrial temperature measurement. End treatment is one of the core processes in their production. First, an annular groove needs to be machined at a predetermined position on the outer protective tube of the thermocouple. Then, the excess section of the protective tube is removed and the magnesium oxide insulating powder filling the tube is cleaned out, so that the internal thermocouple wires can be exposed for subsequent wire welding and end assembly.

[0003] Currently, most thermocouple end cleaning operations are done manually. Operators manually break off excess protective tubes along the annular groove and then clean the internal magnesium oxide powder with a brush or handheld air gun. If the magnesium oxide powder is not thoroughly cleaned, the residual powder will directly affect the subsequent welding quality of the thermocouple wires. At the same time, magnesium oxide powder is easy to fly and scatter during the cleaning process, causing dust pollution at the work site, which poses a health hazard if inhaled. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this utility model proposes a thermocouple end vibrating device for cleaning the ends of cut thermocouples. The device includes a mounting box, a dust collection assembly, several filter assemblies, and a vibrating assembly. The dust collection assembly includes a dust collection box, an air pump, an air outlet pipe, an air jet disc, an air inlet pipe, a dust collection head, and a filter cartridge. The dust collection box is fixed to the lower end of the mounting box. The air pump is installed in the mounting box. Both the air outlet pipe and the air inlet pipe are connected to the air pump, and the air outlet pipe is further away from the air pump. One end of the air pump extends into the mounting box, and the air inlet pipe is connected to the dust collection box; the air jet disc is connected to the end of the air outlet pipe that extends into the mounting box, and the lower end of the air jet disc has several air outlet holes; the dust collection head is installed inside the mounting box, and the upper end of the dust collection head is open, and the dust collection head is connected to the dust collection box; the filter cartridge is connected in series with the air inlet pipe; the filter assembly is set inside the dust collection box, and the end of the air inlet pipe that connects to the dust collection box is located on the side of the filter assembly away from the dust collection head; the vibrating material assembly is set in the mounting box.

[0006] This invention provides a thermocouple end vibration device. During operation, the thermocouple end with a pre-machined annular groove is inserted into the working position inside the mounting box. A cylinder drives the movable clamp to move towards the fixed clamp, clamping and fixing the thermocouple end. Then, the ultrasonic generator built into the fixed clamp is activated, generating high-frequency vibration that is transmitted to the thermocouple through the fixed clamp. The vibration energy is concentrated on the stress concentration area of ​​the annular groove at the end, causing the protective tube end to break off neatly along the annular groove. Simultaneously, the magnesium oxide powder filling the protective tube is loosened under the high-frequency vibration and continuously vibrated out from the break. At the same time, an air pump continuously draws air from the dust collection box through the air inlet pipe, creating a negative pressure environment inside the dust collection box and the connected dust collection head, further dislodging the vibrated protective tube end. The dust collector draws magnesium oxide dust into the dust collection head. Meanwhile, the air pump delivers compressed air to the jet plate through the outlet pipe. The compressed air is then evenly sprayed downwards through several outlet holes at the lower end of the jet plate. This process both pushes the dispersed dust downwards to prevent it from spreading and splashing, and simultaneously blows away the exposed thermocouple wires to prevent magnesium oxide dust residue from adhering. Under the combined action of negative pressure suction and positive pressure blowing, the dust-laden airflow flows into the dust collection box through the dust collection head. As the airflow passes through multiple filtration components in the dust collection box, larger protective tube debris is first intercepted by the upper low-precision filter screen, while fine magnesium oxide dust is filtered and intercepted by the lower high-precision filter screen. Finally, the airflow undergoes deep purification through the filter cartridge. The cleaned airflow then flows back to the air pump's inlet through the inlet pipe, completing a closed-loop air circulation.
