Description

Technical Field

[0001] The utility model relates to the technical field of production of unburned magnesia-calcium carbon bricks, in particular to a drying device for unburned magnesia-calcium carbon bricks. Background Art

[0002] Unfired magnesia-calcium carbon bricks, also known as unfired magnesia-calcium carbon bricks, are alkaline refractory materials with MgO, CaO and C as the main components. They are widely used in off-furnace refining and have excellent slag erosion resistance, slag permeability, thermal shock stability and thermal conductivity. Among them, attention should be paid to the hydration phenomenon. Unfired magnesia-calcium carbon bricks are made by high-pressure pressing, electric heating and drying.

[0003] For example, the utility model with application number CN202320201568.4 discloses a heating device for an unburned magnesium-calcium carbon brick drying kiln. The utility model lifts the top cover to the highest point through a lifting mechanism, and then places the bottom of the unburned magnesium-calcium carbon brick into the storage shell to facilitate loading. The lifting mechanism then drives the top cover and the self-spinning storage mechanism to move down, so that the top cover fits to the top of the drying box, and then starts the electric heating wire to heat and dry the unburned magnesium-calcium carbon bricks in the self-spinning storage mechanism. At the same time, the large gear is driven to rotate by the first motor, and the small gear and the transmission shaft are driven to rotate by the large gear, and the storage shell is driven to rotate by the transmission shaft, so that the unburned magnesium-calcium carbon bricks rotate around the transmission shaft continuously, thereby making various parts of the unburned magnesium-calcium carbon bricks. They can all be brought close to the electric heating wire to be heated more evenly, thereby increasing the drying speed. After drying, the top cover and the spin storage mechanism are driven by the lifting mechanism to facilitate the removal of the unburned magnesium-calcium carbon bricks on the spin storage mechanism, which is convenient for unloading. However, in the actual use of this type of equipment, the lifting mechanism will drive the unburned magnesium-calcium carbon bricks to the upper end of the equipment, making their overall position higher. Therefore, when taking and placing, it is necessary to use equipment such as a ladder. At the same time, when replacing the unburned magnesium-calcium carbon bricks, they need to be replaced one by one, resulting in a long downtime of the equipment, affecting the overall production efficiency of the unburned magnesium-calcium carbon bricks.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a non-fired magnesium calcium carbon brick drying device is provided. Utility Model Content
