Generally, the kiln furniture frame is composed of columns, cross beams and backing plates. The traditional backing plate has insufficient heat air circulation and thermal shock stability. The gap size generated during the butt joint of the backing plates is relatively large. The stability of the kiln furniture needs to be improved, the firing effect of the ceramic products needs to be improved, and the firing energy consumption is relatively high. Summary of the Invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides a kiln furniture backing plate and a frame.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A kiln furniture backing plate includes a backing plate body. A plurality of ventilation holes are arranged on the backing plate body. Inverted "mountain"-shaped connection structures for connecting with the ends of another backing plate body are arranged at both opposite ends of the backing plate body.

[0006] Hook connection notches are formed on the inner end faces of both side edges of the connection structure.

[0007] The notch width of the hook connection notch is the same as the width of the notch groove wall.

[0008] An external ventilation slot opening is formed in the middle of the outer end face of the connection structure.

[0009] The ventilation holes are circular, triangular, quadrilateral, long-waisted or trapezoidal in shape.

[0010] The ventilation holes are arranged on the backing plate body in a single row, double rows, staggered and / or arbitrary arrangement.

[0011] A kiln furniture frame includes a kiln furniture backing plate, and also includes a plurality of columns and auxiliary cross beams. The columns are of a hollow structure. Two columns for erecting the auxiliary cross beams are longitudinally arranged on both side faces of the columns. The auxiliary cross beams penetrate through the through holes. A plurality of backing plate bodies are connected to the auxiliary cross beams. Adjacent two backing plate bodies are alternately hooked end to end through the hook connection notches of the connection structures. The notch groove wall on the upper side of the connection structure of the previous backing plate body is hooked into the hook connection notch on the lower side of the connection structure of the next backing plate body. A plurality of columns are arranged in multiple rows and fixed on the kiln car.

[0012] Two cross beam through holes penetrating both side edges are arranged on the connection structure. When adjacent two backing plate bodies are hooked, the corresponding cross beam through holes communicate with each other, and the auxiliary cross beams penetrate through the cross beam through holes.

[0013] The beneficial effects of the present utility model are as follows: Vent holes are provided on the pad body of the present utility model. After the pad bodies are connected, due to the special connection structure, gaps are generated between the horizontal and vertical pad bodies. The existence of the vent holes and the pad gaps enhances the heat circulation of the pads. The pad bodies are interconnected through a hooked connection structure, with a small butt gap, and can be reinforced by auxiliary crossbeams, increasing the thermal shock stability of the kiln furniture and improving the firing effect of the kiln furniture.

The width of the hook - connecting notch 13 is the same as the width of the notch wall 15 of the notch, which facilitates the adjacent two backing plates 1 to be alternately hooked end - to - end through the hook - connecting notches 13 of the connecting structure 12.

[0026] An external ventilation slot 16 is formed in the middle of the outer end face of the connecting structure 12. The external ventilation slot 16 increases the ventilation port area and improves the heat gas flowability of the backing plate 1.

[0027] The ventilation holes 14 are circular, triangular, quadrilateral, long - waisted or trapezoidal in shape. The ventilation holes 14 are arranged in a single row, double rows, staggered and / or arbitrary arrangement on the backing plate body 11. The ventilation holes 14 and the external ventilation slot 16 increase the heat gas flowability between the backing plates 1.

[0028] A kiln furniture frame includes kiln furniture backing plates, and also includes a number of columns 3 and auxiliary cross - beams 2. The columns 3 are of hollow structure. Two rows of through - holes 4 for mounting the auxiliary cross - beams 2 are longitudinally arranged on both side faces of the columns 3. The auxiliary cross - beams 2 penetrate through the through - holes 4. A plurality of backing plates 1 are laid on the auxiliary cross - beams 2. The adjacent two backing plates 1 are alternately hooked end - to - end through the hook - connecting notches 13 of the connecting structure 12. The notch wall 15 on the upper side of the connecting structure 12 of the previous backing plate 1 is hooked into the hook - connecting notch 13 on the lower side of the connecting structure 12 of the next backing plate 1. A plurality of columns 3 are arranged in multiple rows and fixed on the kiln car 5.

[0029] Two cross - beam through - holes 17 penetrating both sides are provided on the connecting structure 12.
