Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting circulation kneading, in particular to a heat-conducting oil circulation type kneading device. Background Art

[0002] In the production process of graphite electrodes, a general kneading pot is heated by electrically heating the heat transfer oil. In this process, the heat transfer oil is heated and expanded, and part of the heat transfer oil overflows. The heating temperature of the heat transfer oil generally exceeds 200°C. When the heat transfer oil temperature exceeds 60°C, it will oxidize and carbonize when in contact with air. In the prior art, during the process of adding heat transfer oil and turning the kneading pot, the original high-temperature heat transfer oil in the kneading pot will come into contact with air, causing the heat transfer oil to oxidize and carbonize and hang on the wall, forming solid residues, affecting the thermal field temperature of the kneading pot, increasing the generation of waste, and affecting product quality.

[0003] The Chinese patent document with the announcement number CN219142046U discloses an intermittent kneading equipment temperature measuring device and a kneading equipment. When temperature measurement is not required, the temperature measuring couple is placed outside the kneading equipment to reduce the heat radiation received, thereby improving the temperature measurement accuracy; however, it does not solve the problem of heat transfer oil oxidation, carbonization and wall adhesion, and the formation of solid residues;

[0004] In summary, how to design a heat transfer oil circulation kneading device so that it can prevent the high-temperature heat transfer oil from directly contacting the air to oxidize and carbonize and hang on the wall to form solid residues, and prevent it from affecting the thermal field temperature of the kneading pot and generating waste has become a problem that needs to be solved at present.
