Abstract

The invention relates to a planetary vacuum stirrer dynamic temperature measuring device comprising a cross beam, an upper barrel, a planetary part, a stirring barrel, a high-speed transmission part, a low-speed transmission part and a dynamic temperature measuring part; the dynamic temperature measuring part comprises a hollow sleeve, a through-hole type conductive slip ring, a slip ring fixing frame, a temperature measuring wire, a temperature measuring rod, a temperature measuring probe and a temperature information receiving / displaying device; the through-hole type conductive slip ring is composed of a slip ring stator and a slip ring rotor; the hollow sleeve is fixed on a hollow low-speed shaft; the slip ring rotor is fixed on the hollow sleeve, and the slip ring stator is arranged on the cross beam through the sliding ring fixing frame; the temperature information receiving / displaying device is connected with the slip ring stator by the temperature measuring wire; the temperature measuring rod is fixed on a planetary box, and the temperature measuring probe is arranged at the lower part of the temperature measuring rod. The dynamic temperature measuring device can more accurately detect a real-time temperature of a material, is suitable for a vacuumizing state, also has the advantages of simpler structure, long service life of the conductive slip ring and good equipment stability, and can simply realize vacuum retaining of equipment.

Description

technical field [0001] The invention relates to a temperature measuring device, in particular to a dynamic temperature measuring device for a planetary vacuum mixer. Background technique [0002] The planetary dispersing and mixing equipment used in chemical, rubber, electronic slurry and other industries often needs to stir and mix the materials at room temperature or under heating. In order to make the materials have more stable characteristics, it is necessary to The real-time temperature is monitored to control its stability within a certain range, and a vacuum is required during the material mixing process to ensure the quality and efficiency of material mixing. [0003] At present, the material temperature measurement methods used by the planetary dispersion mixer are: 1. Static temperature measurement method (generally installed on the side wall or bottom of the barrel, and the temperature measuring probe is close to the inner wall of the barrel to detect the temperat...

Problems solved by technology

Its disadvantages: 1. The structure is complex, especially for planetary vacuum models; 2. The middle of the already slender high-speed shaft needs to be pierced with wires to pass through the wires, which is difficult to process and also reduces the strength of the shaft; 3. Sliding The life of the slip ring is easily reduced under high speed conditions. The high speed shaft speed is generally 1000~6000RPM. In such a high speed and frequent start-up and harsh environment, the life of the slip ring is greatly reduced.
