Embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but is not restricted to protection model of the present utility model
Enclose.
As shown in Figure 1 to Figure 2, a kind of accumulation of heat magnesia brick, magnesia brick is cuboid, and magnesia brick outer wall is provided with two bar-shaped troughs 1, two
Arc link slot 2 is provided between individual bar-shaped trough 1, magnesia brick, which is provided with cavity 3, cavity 3, is provided with asbestos board, the outer wall and inwall of magnesia brick
On the opening that is equipped with opening, outer wall be more than opening on inwall, the opening in opening and inwall on outer wall forms through hole
4, the connection end of the inwall of described magnesia brick is provided with chamfering 5.
The through hole 4 of the open-type in opening and inwall on described magnesia brick outer wall is cone-shaped hole；Gas can be formed
Pressure difference, accumulation of heat speed can be accelerated.
Through hole 4 on described magnesia brick wall is several, and several uniform arrays of through hole 4 are on the wall of magnesia brick；It can carry out many
Point accumulation of heat, accelerates accumulation of heat speed.
Described asbestos board is cellular asbestos board.
Quartz sand is filled with described cellular asbestos board.
As preferred embodiment of the present utility model, a kind of accumulation of heat magnesia brick, magnesia brick is cuboid, and magnesia brick outer wall is provided with two
Arc link slot 2 is provided between individual bar-shaped trough 1, two bar-shaped troughs 1, magnesia brick is provided with the cavity 3 of rectangle structure, rectangle structure
Cavity 3 in be provided with asbestos board, the opening on opening, outer wall is equipped with the outer wall and inwall of magnesia brick more than opening on inwall
Mouthful, the opening in opening and inwall on outer wall forms through hole 4, and the connection end of the inwall of described magnesia brick is provided with chamfering 5.
As another embodiment of the present utility model, a kind of accumulation of heat magnesia brick, magnesia brick is cuboid, and magnesia brick outer wall is provided with two
