Description

Technical Field

[0001] The utility model relates to the technical field of aluminum prebaked anode production, in particular to an online temperature measuring device for a kneading pot in a forming process of aluminum prebaked anode, aiming to change the traditional manual sampling and temperature measuring operation mode. Background Art

[0002] In the production process of prebaked anodes for aluminum, kneading is the process of mixing aggregates, powders, raw and cooked crushed materials and other dry materials of different particle sizes with a certain amount of liquid asphalt in a kneading pot at a certain temperature after being quantitatively measured according to the required proportion of the formula, so as to achieve a uniform, dense paste with a certain plasticity.

[0003] Kneading is an important step in the production of prebaked anodes for aluminum. The quality of kneading directly affects the quality of the raw anode blocks, and the final temperature of the material after kneading plays a decisive role. The traditional method of measuring temperature with a kneading pot is to insert a temperature measuring resistor downward from the top of the pot. However, as time goes by, the paste will adhere to the upper space of the kneading pot and wrap the temperature measuring resistor probe, affecting the accuracy of temperature measurement. If the length of the temperature measuring resistor is extended, it will interfere with the stirring blade, squeeze the resistor and deform it, or even break it.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop an online temperature measuring device for a kneading pot. Utility Model Content
