Description

Technical Field

[0001] The utility model relates to a tool for taking out heat-insulating bricks for a high-temperature furnace door, belonging to the field of heat-insulating brick taking and placing equipment. Background Art

[0002] High-temperature furnace insulation bricks are a crucial material used within high-temperature furnaces, primarily providing insulation. Temperatures within high-temperature furnaces are often extremely high. If no measures are taken, the external temperature can transfer into the furnace through conduction and radiation, resulting in significant energy loss and heat waste. High-temperature furnace insulation bricks effectively isolate the temperature difference between the inside and outside of the furnace, mitigating temperature conduction and radiation, thereby reducing internal temperature loss and energy waste, improving the furnace's energy efficiency, and ultimately achieving energy conservation and consumption reduction. However, the material of high-temperature insulation bricks is often brittle, and improper impact or knocking can damage the bricks. Furthermore, during the cooling process, the temperature of some high-temperature furnaces is difficult to reduce due to their excellent insulation performance. Furthermore, during certain experiments requiring high-temperature operation, the insulation bricks remain extremely hot, making manual placement and removal of insulation bricks difficult and dangerous. Existing tools have fixed dimensions and must be adjusted to the size of the insulation bricks, making them inconvenient. Therefore, a simple and effective tool is needed to easily and safely remove insulation bricks from the closed door of a high-temperature furnace. Utility Model Content

The clamping device is actually connected to the handle 1 via the fixing plate 11. This device is used in conjunction with the insertion holes for fixing insulation bricks and is specifically designed for removing and placing insulation bricks. The spacing between the adjustable jaw 5 and the fixed jaw 3 allows for adjustable clamping width to accommodate insulation brick insertion holes of varying widths. The design of this device fully considers the shape and size of insulation bricks to ensure their wide applicability. When using this tool, the operator first needs to adjust the width of the clamping device according to actual needs to ensure that the clamping device fits perfectly into the hole in the insulation brick. After the first adjustment, if the insulation brick is not replaced, no further adjustment is required. Then, the clamping device of the tool, specifically the fixed clamping jaw 3 and the adjustment clamping jaw 5, is gently inserted into the insulation brick hole at the furnace door. Once inserted, the insulation brick can be removed. It is preferred to provide an insulating layer on the clamping device to effectively prevent high temperature conduction and reduce the risk of burns to the operator. After removing the insulation brick, subsequent experimental operations can be carried out as needed.
