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 plate-type 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 fire dissipation and smoke exhaust structure for the plate-type rock slab hot bending kiln to solve the above problems. Utility Model Content
[0004] The utility model aims to provide a fire dispersion and smoke exhaust structure for a plate-type rock slab hot bending kiln to solve the above-mentioned deficiencies in the prior art.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A fire dispersion and smoke exhaust structure for a plate-type rock slab hot-bending kiln comprises a kiln body, a heat dissipation port is provided on the outer wall at the top of the kiln body, upper and lower distributed holders are fixedly mounted on the inner walls on both sides of the kiln body, an upper perforated refractory board and a lower perforated refractory board are respectively placed on the upper and lower holders, and a plurality of ventilation holes distributed in an array are provided on the outer walls at the tops of the upper and lower perforated refractory boards.
[0007] Furthermore, a cover plate is placed above the heat dissipation port, and both the cover plate and the heat dissipation port are rectangular structures.
[0008] Furthermore, pads are fixedly provided on the inner walls of both sides of the kiln body, and refractory rods are fixedly installed above the pads.
[0009] Furthermore, the upper and lower layers of the holders located on the inner wall of the same side of the kiln body are staggered, and the upper layer of perforated refractory plates and the lower layer of perforated refractory plates are staggered.
[0010] Furthermore, an upper solid fire-resistant board and a lower solid fire-resistant board may be fixedly mounted on the upper and lower layers of the bases, wherein the number of the upper solid fire-resistant board is one, and the number of the lower solid fire-resistant board is two.
[0011] Furthermore, a ventilation gap is left between the two lower solid refractory boards, and the ventilation gap is located directly below the center line of the upper solid refractory board, and the width of the upper solid refractory board is smaller than the width of the heat dissipation port.
[0012] In the above technical scheme, the utility model provides a fire dispersion and smoke exhaust structure for a plate-type rock slab hot bending kiln, which has the following beneficial effects:
[0013] (1) By arranging an upper layer of perforated refractory plates and a lower layer of perforated refractory plates below the heat dissipation port, and staggering the positions of the through holes between the upper layer of perforated refractory plates and the lower layer of perforated refractory plates, the through hole heat dissipation effect can be well achieved, and at the same time, dust can be well prevented from falling from the heat dissipation port.
[0014] (2) The stacked structure consisting of an upper solid refractory board and two lower solid refractory boards can also assist in dispersing fire and heat, and can also effectively prevent dirt from falling, which plays a good role in protecting the rock slab workpieces inside the kiln and improves the product yield.
