[0001] The invention relates to the technical field of roller kilns, and in particular to a water-cooled heat-insulating structure of a roller kiln firing zone box. Background Art

[0002] Roller kiln is also called roller bottom kiln; it is mainly used for the production of ceramic building materials such as tiles. Roller kiln is a continuous firing kiln, a tunnel kiln with rotating rollers as the carrier of the green body. The ceramic products are placed on many closely spaced horizontal refractory rollers, and the rotation of the rollers transfers the ceramics from the kiln head to the kiln tail, so it is called a roller kiln.

[0003] As mentioned above and in the prior art, the heat in the roller kiln is too high, the heat can easily damage the supporting bearings, and the ceramic rollers are subjected to excessive force, so only large-diameter ceramic rollers can be used for support. However, the gap between adjacent large-diameter ceramic rollers is large, which will leave marks on the surface of the tiles when the tiles are transported. Therefore, it is urgent to design a water-cooled and heat-insulating structure for the box body of the roller kiln firing zone to solve the above problems. Summary of the invention

The cold water jacket 3 is located between the support frame 4 and the roller kiln body 1. Cooling water circulates in the cold water jacket 3, which can insulate the heat transmitted from the roller kiln body 1, and can prevent the support bearing 5 and the support frame 4 from being burned by the high heat transmitted from the roller kiln body 1.

[0023] By setting: cooling water circulating in the cold water jacket 3, plus the function of the heat-insulating zirconium blanket, the heat transmitted from the roller kiln body 1 can be insulated, thereby preventing the high heat transmitted from the roller kiln body 1 from burning the support frame 4 and the support bearing 5, and extending the service life of the support bearing 5 and the support frame 4, thereby achieving the heat insulation function.

[0024] In one embodiment provided by the present invention, Figure 1 and Figure 2 As shown, a transverse seat 6 is fixedly provided on the outer wall of the top end of the support seat 2 , and a mounting seat 8 is fixedly provided at one end of the transverse seat 6 , and the mounting seat 8 is used to support the mounting seat 8 .

Since the distance between the force-bearing ends is reduced , a ceramic roller 7 with a smaller diameter can be selected, so that the gap between two adjacent ceramic rollers 7 will be greatly reduced, which can greatly reduce the traces left by the ceramic roller 7 on the tile surface and protect the surface of the ceramic roller 7. Then, due to the excessive heat during operation in the roller kiln body 1, it will be dissipated. The cooling water circulating inside the cold water jacket 3 can insulate the heat transmitted from the roller kiln body 1, thereby realizing the insulation function, extending the service life of the support bearing 5 and the support frame 4, and preventing the support frame 4 and the support bearing 5 from being burned out by high heat.
