Description

Technical Field

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

[0002] The rock slab hot bending kiln mainly uses high temperature to soften the rock slab, and then uses a mold to process the rock slab into a specific shape, such as a concave wash basin, and then naturally cools and hardens. 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 slab cannot be taken out of the kiln immediately, otherwise it will be rapidly cooled and cracked, and it needs to be placed in the kiln to slowly cool for 4-5 hours. Therefore, it is urgent to design a fire-dispersing flue structure for the rock slab hot bending kiln to solve the above problems. Utility Model Content

[0003] The utility model aims to provide a fire dispersion flue structure for a rock slab hot bending kiln to solve the above-mentioned deficiencies in the prior art.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A fire-dispersing flue structure for a rock slab hot-bending kiln comprises a kiln body, a temperature probe inserted into the kiln body is fixedly arranged on the outer wall of one side of the kiln body, an air flow opening is opened on the outer wall of the top of the kiln body, and the air flow opening is covered with a cover plate, and upper and lower refractory rods placed horizontally are fixedly installed on the inner walls on both sides of the kiln body, and the lower refractory rods are symmetrically arranged on both sides and located below the upper refractory rods.

[0006] Preferably, there are several kiln bodies, and the several kiln bodies are connected by a splicing structure.

[0007] Preferably, an observation window is provided on the outer wall of one side of the kiln body, and transparent high-temperature glass is fixedly installed inside the observation window.

[0008] Preferably, a feed port is provided at one end of the kiln body, and a door panel is provided on the outer side of the upper portion of the feed port, and a guide rail extending to the inside of the kiln body is fixedly installed at the lower portion of one side of the feed port.

[0009] Preferably, a mold is slidably mounted on the outer wall at the top of the guide rail, and a workpiece rock plate is fixedly arranged above the mold.

[0010] Preferably, the upper refractory rods and the lower refractory rods are both composed of a plurality of refractory rod monomers, and the upper refractory rods are located directly below the air flow port, and an air flow channel connecting the kiln body and the air flow port is left between the upper refractory rods and the lower refractory rods.

[0011] In the above technical scheme, the utility model provides a fire-scattering flue structure of a rock plate hot-bending kiln, which has the following beneficial effects:

[0012] The main core point in this application is the flue structure formed by the upper and lower layers of refractory sticks. After the rock slab is heated in the kiln, the cover is opened by external force, and then the smoke in the kiln will be discharged, and the external cold air will gradually enter the kiln, and the temperature in the kiln will gradually cool down through the rock slab, so that the processed rock slab will cool and take shape.

[0013] The functions of the flue structure in the present application are: 1. The installation position of the upper refractory stick is just aligned with the cover plate, thus forming a shielding to prevent ash from falling into the kiln when the cover plate is opened and closed, thereby damaging the processed workpieces and forming defective products, effectively preventing dirt from falling; 2. By setting up an upper and lower two-layer refractory stick structure, the cold air entering the kiln from the outside cannot directly reach the kiln, and first passes through the obstruction of the upper refractory stick, and then enters the area corresponding to the lower refractory stick through the gaps on the left and right sides, and then gradually enters the kiln. Since the refractory sticks themselves are of high temperature, through the obstruction of the upper and lower layers of refractory sticks, in this process, the air entering from the outside will be heated to a certain temperature by the refractory sticks, which can prevent the workpieces in the kiln from bursting due to rapid cooling, and can gradually reduce the temperature in the kiln.

[0021] Specifically, in this embodiment, a kiln body 1 is included, and the kiln body 1 is a rock slab hot bending kiln. There are several kiln bodies 1, and the several kiln bodies 1 are connected by a splicing structure to form a product production line of a certain length, so as to realize continuous high-temperature processing and molding of products. A temperature probe 3 inserted into the kiln body 1 is fixedly arranged on the outer wall of one side of the kiln body 1. The local temperature inside the kiln can be penetrated in real time through the temperature probe 3, which is convenient for people to control the temperature of product molding. The outer wall of the top of the kiln body 1 is opened with a gas The flow port 10 discharges the smoke inside the kiln from the flow port 10, and allows the external cold air to enter the inside of the kiln from the flow port 10, so as to cool the products inside the kiln and avoid cracking of the rock slab products. The air flow port 10 is covered with a cover plate 4, and the cover plate 4 is an openable structure, so as to realize the opening and closing of the air flow port 10. The inner walls on both sides of the kiln body 1 are fixedly installed with horizontally placed upper refractory rods 11 and lower refractory rods 12, and the lower refractory rods 12 are symmetrically arranged on both sides and are located below the upper refractory rods 11.

Through the observation window 2, people can conveniently observe the product production situation inside the kiln and adjust the kiln parameters in time.

[0023] As another embodiment provided by the utility model, a feeding port 6 is provided at one end of the kiln body 1, and a door panel 5 is provided on the outer side of the upper part of the feeding port 6, which has a good sealing effect on the kiln body 1 and ensures the temperature inside the kiln. A guide rail 7 extending to the inside of the kiln body 1 is fixedly installed on the lower part of one side of the feeding port 6; a mold 8 is slidably installed on the outer wall of the top of the guide rail 7, and a workpiece rock plate 9 is fixedly installed above the mold 8.
