Description

Technical Field

[0001] The utility model relates to the technical field of hot bending kilns, and in particular to a fire dispersion and smoke exhaust structure of a tubular rock slab hot bending kiln. Background Art

[0002] As a new type of material, ceramic rock slabs can be used in cabinets, furniture, floors, walls, etc., especially curved ceramic rock slabs can be used in the design of curved spaces to ensure the integrity and unity of the entire space. Curved ceramic rock slabs are obtained by hot bending ceramic rock slabs in a kiln. The temperature in the kiln is about 1200 degrees Celsius during operation, and it takes 4-5 hours to heat. Due to the high temperature, the processed rock slabs cannot be taken out of the kiln immediately, otherwise they will be rapidly cooled and cracked, and need to be placed in the kiln to slowly cool for 4-5 hours.

[0003] Generally, a heat dissipation port is set above the kiln to assist the kiln in cooling down and improve the processing efficiency and quality of the rock slab. However, the open kiln heat dissipation port is prone to dust falling, which causes the rock slab to be contaminated and results in defective products. Therefore, it is urgent to design a tubular rock slab hot bending kiln fire dissipation and smoke exhaust structure to solve the above problems. Utility Model Content

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-3 As shown, an embodiment of the utility model provides a tubular rock slab hot bending kiln fire dispersion and smoke exhaust structure, including a kiln 1, a plurality of through holes 8 are opened on the top of the kiln 1, and a cover plate 6 covering the through holes 8 is placed on the top outer wall of the kiln 1, and a refractory rod 7 that penetrates into the interior of the kiln 1 is fixedly inserted into the through hole 8, and the refractory rod 7 is a hollow structure.

[0021] Specifically, in the present embodiment, a kiln 1 is included, and a plurality of through holes 8 are opened on the top of the kiln 1. The through holes 8 are circular hole structures, which are convenient for fixing and installing refractory rods 7. A cover plate 6 covering the through holes 8 is placed on the top outer wall of the kiln 1. The tops of the plurality of refractory rods 7 are covered by the cover plate 6, thereby achieving a sealing effect of the kiln. The interior of the through holes 8 is fixedly plugged with refractory rods 7 that penetrate into the interior of the kiln 1, and the refractory rods 7 are hollow structures. The hollow structure of the refractory rods 7 facilitates the discharge of smoke inside the kiln, thereby achieving the purpose of dispersing the fire in the kiln.

[0022] The utility model provides a tubular rock slab hot bending kiln fire dispersion and smoke exhaust structure, which adopts a hollow refractory rod 7 to connect the inside of the kiln 1 with the outside. After the rock slab product is fired, the cover plate 6 is opened to allow the smoke inside the kiln 1 to pass through the hollow refractory rod 7, thereby achieving the purpose of better kiln fire dispersion.

[0023] As an embodiment provided by the utility model, a guide rail 2 is fixedly installed inside one end of the kiln 1, and a mold 3 is slidably placed above the guide rail 2, a rock slab workpiece 9 is placed on the outer wall of the top of the mold 3, and the rock slab workpiece 9 is placed above the mold 3, and enters and exits the kiln as the mold 3 moves on the guide rail 2; door panels 4 are provided on the outer walls at both ends of the kiln 1, and the door panels 4 are used to achieve a sealing effect on the kiln, and the door panel 4 at one end is an openable structure; a pad is fixedly installed inside the kiln 1, and a number of heating rods 5 distributed at equal distances are fixedly installed above the pad, and the heating rods 5 are used to heat the inside of the kiln, which helps to ensure the temperature inside the kiln.

[0024] As another embodiment provided by the utility model, the refractory stick 7 is of an L-shaped structure, and the top plane of the refractory stick 7 is flush with the top plane of the through hole 8. The flush structure facilitates the sealing of the through hole 8 and the top of the refractory stick 7 by the cover plate. The adopted L-shaped structure facilitates the dispersion of smoke inside the kiln, thereby preventing dust outside the kiln from falling into the kiln along the refractory stick 7 to avoid staining the rock slab products inside. The refractory sticks 7 are arranged in a longitudinal straight line at equal distances, and the number of the refractory sticks 7 is 8-12, and the number of the refractory sticks 7 is preferably 10, so as to achieve more efficient smoke exhaust and fire dispersion for the kiln.
