A heating device (not shown in the figure) is provided on the furnace bottom 11, and a hot bending mold (not shown in the figure) is installed on the heating device;

[0041] The cooling system 3 includes an annular cooling pipeline 31. The annular cooling pipeline 31 is arranged around the outer side of the furnace wall 12. A plurality of ventilation holes 13 penetrating through the entire furnace wall 12 are opened at the periphery of the furnace wall 12. The annular cooling pipeline 31 is communicated with the ventilation holes. The opening positions of the ventilation holes 13 are arranged on the outer periphery of the hot bending mold.

[0042] In this application, by designing a cooling system 3 on the outer periphery of the furnace body 1 and delivering a cold source to the periphery of the hot bending mold, during the hot bending process of the furnace, targeted cooling can be performed on the hot bending position of the rock slab integrated plate. The cooling effect is uniform and significant, which is beneficial to uniformly reducing the temperature of the furnace, avoiding defects such as cracking and deformation when the rock slab is hot bent, and effectively ensuring that the curved surface radian of the product meets the standard, and the rock slab surface is smooth and has no pores.

[0043] As a further preferred solution, the cooling system 3 further includes a blower 32. The air outlet of the blower 32 is communicated with the annular cooling pipeline 31. In this application, by designing the blower 32 as a cold source output point, cold air is delivered into the furnace body 1 in an air-cooling manner and at the periphery of the hot bending mold. Such a cooling effect is good, uniform, and the cost is low.

[0044] As a further preferred solution, a plurality of viewing holes 14 are opened on the outer periphery of the furnace wall 12. The opening positions of the viewing holes 14 are arranged on the outer periphery of the hot bending mold.

[0045] As a further preferred solution, in order to further supplement the heating effect, a heating device (not shown in the figure) is also provided on the furnace cover.

[0046] In this application, a plurality of viewing holes 14 are designed on the outer peripheral furnace wall 12 of the hot bending die.

[0049] In this application, by adding a cross beam 4 inside the furnace, especially on the furnace cover 2, this design is used in combination with the arc-shaped forming device for the water outlet of the slate integrated dish to process the arc-shaped water outlet of the slate integrated dish. This forming device is beneficial to improving the opening stability of the arc-shaped water outlet of the integrated dish. Its structure and usage method fully refer to the relevant patents of the inventor of this case regarding the arc-shaped forming device for the water outlet of the slate integrated dish (patent numbers ZL202420803081.8, ZL202420383190.9, ZL202410222494.1), which will not be elaborated here. Specifically, the cross beam 4 in this solution replaces the mounting bracket in an arc-shaped forming device for the water outlet of a ceramic slate integrated basin in ZL202420803081.8. The cross beam 4 is installed on the furnace cover 2, improving the installation stability of the central shaft rod and thus ensuring the quality of the arc-shaped forming of the water outlet of the slate integrated basin.

[0050] As a further preferred solution, the lifting type slate hot bending kiln further includes a lifting device 5 and a bracket 6. The lifting device 5 is installed on the bracket 6, and the furnace cover 2 is movably installed on the bracket 6. The lifting device 5 drives the furnace cover 2 to move up and down.

The added lifting device 5 can automatically cover or open the furnace cover 2 of the kiln body 1 for loading slate and unloading products, reducing labor costs.

[0051] In this technical concept, the way of movably installing the furnace cover 2 on the bracket 6 can be implemented in various ways, including but not limited to the cooperation of a chute and a pulley, the cooperation of a slider and a guide rail, etc. As a further preferred solution, the bracket 6 includes a plurality of columns 61, a chute 62 is provided in the column 61, and a pulley 21 that slides in cooperation with the chute is provided on the furnace cover 2; or a pulley is provided in the column, and a chute that slides in cooperation with the pulley is provided on the furnace cover 2.

[0052] As a further preferred solution, the lifting device 5 includes a motor 51, a gear linkage shaft 52, a lead screw shaft 53, and a bushing 54. The motor 51 and the bushing 54 are both installed on the bracket 6. The power output end of the motor 51 is drivingly connected to the bushing 54 through the gear linkage shaft 52. The lead screw shaft 53 is disposed in the bushing 54 and is threadedly connected to the bushing 54. The bottom of the lead screw shaft 53 is fixedly connected to the furnace cover 2.

Since the open mouth is designed at the top of the kiln body 1, the volume and weight of the used furnace cover 2 are relatively large. In order to further improve the lifting stability and reliability of the furnace cover 2, in this application, through the cooperation of the lead screw and the bushing 54 at the corner positions of the furnace cover 2, synchronous linkage lifting is realized.
