Technical Field
[0001] The utility model relates to the field of alumina products, in particular to a support brick for the inner base of an alumina ceramic tube furnace. Background Art
[0002] Alumina ceramic tubes have good wear resistance and high temperature resistance characteristics, can be applied to specific environments, and are generally used as lining tubes. They have the following performance characteristics: wear resistance: under the same conditions, they are 10 times more wear-resistant than ordinary pipe rods; corrosion resistance: the lining ceramics and inorganic adhesives can resist acid and alkali corrosion; medium temperature resistance: they can operate at 350°C for a long time and can meet general working conditions.
[0003] During the processing of alumina ceramic tubes, they need to be processed in a high-temperature furnace. Generally, support bricks are used to fix the alumina ceramic tubes. Multiple placement grooves are usually opened on the support bricks for placement. The support bricks are only used as support tools. Such support bricks cannot be selectively used according to the different sizes of alumina ceramic tubes. When it comes to placing particularly large-diameter alumina ceramic tubes, they cannot be placed. Moreover, the support bricks themselves lack a protection structure. The two sides and the middle placement grooves are all open structures, and it is easy for the alumina ceramic tubes to collide with each other during the movement process, resulting in damage.
[0004] Therefore, the utility model provides a support brick for the inner base of an alumina ceramic tube furnace, which provides support for multi-form alumina ceramic tubes. Large-diameter alumina ceramic tubes can be placed on both sides of the support brick body, and the large-diameter alumina ceramic tubes are supported by the V-shaped groove bottom, with balanced support, and can be fully heated in a compact space. Multiple small-diameter alumina ceramic tubes can be placed in the center of the support brick body, and the small-diameter alumina ceramic tubes are carried by the arc groove bottom, with high fitting degree and stable fixation. Summary of the Utility Model
[0005] The main technical problem to be solved by the utility model is to provide a support brick for the inner base of an alumina ceramic tube furnace, which is a multi-rod support brick that can provide support for multi-form alumina ceramic tubes.
[0006] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a support brick for the inner base of an alumina ceramic tube furnace, including a support brick body. Single-rod seat grooves are provided on both sides of the support brick body, and a multi-rod arrangement seat groove is provided in the center of the support brick body. The bottom of the single-rod seat groove is provided with a V-shaped groove bottom, and high-enclosure refractory brick walls are provided on both sides of the V-shaped groove bottom. The two sides of the multi-rod arrangement seat groove are enclosed by the high-enclosure refractory brick walls between the adjacent single-rod seat grooves. Multiple arc groove bottoms are arranged at equal intervals at the bottom of the multi-rod arrangement seat groove, and low partition refractory brick walls are provided at the connection parts of the arc groove bottoms.
[0007] In a preferred embodiment of the present utility model, the high-enclosure refractory brick wall stands upright above the support brick body. The single-rod seat groove and the multi-rod arrangement seat groove are separated by the high-enclosure refractory brick wall, and both sides of the support brick body are enclosed by the high-enclosure refractory brick wall.
[0008] In a preferred embodiment of the present utility model, the high-enclosure refractory brick walls are all of the same height.
[0009] In a preferred embodiment of the present utility model, the low partition refractory brick wall is trapezoidal.
[0010] The beneficial effects of the present utility model are as follows: The present utility model can provide a multi-rod support brick for supporting multi-morphology alumina ceramic tubes. Large-diameter alumina ceramic tubes can be placed on both sides of the support brick body, and the large-diameter alumina ceramic tubes are supported by the V-shaped groove bottom, with balanced support, and can be fully heated in a compact space. Multiple small-diameter alumina ceramic tubes can be placed in the center of the support brick body. The small-diameter alumina ceramic tubes are carried by the arc-shaped groove bottom, with high fitting degree and stable fixation. Moreover, the contact degree between the small-diameter alumina ceramic tubes and the arc-shaped groove bottom is high, and the heating is more uniform. There is a low partition refractory brick wall between the small-diameter alumina ceramic tubes to prevent interference with each other. BRIEF DESCRIPTION OF THE DRAWINGS
