Kiln furniture structure with height-adjustable shelf board

Abstract

The kiln furniture structure comprises a plurality of layers of shed plates arranged in a kiln car and a shed plate supporting structure arranged below the shed plates, the shed plate supporting structure comprises stand columns and cross beams, and refractory bricks are arranged at the bottom of the kiln car. The bottoms of the stand columns of the shed plate supporting structure located below the lowermost shed plate in the multiple layers of shed plates are inserted into the refractory bricks and filled with energy-saving sand and high-purity blankets. U-shaped grooves are formed in the tops of the stand columns, a set of cross beam holes penetrating through the stand columns are formed in the front faces of the stand columns in the axial direction of the stand columns, the cross beams are arranged in the U-shaped grooves or the cross beam holes of the stand columns, the shed plates are arranged on the cross beams, and the shed plates on the same layer are connected through shed plate connectors. According to the tunnel kiln, the weight of kiln furniture is greatly reduced by fully utilizing the light weight of the shed plates, the stand columns and the cross beams, and one tunnel kiln uses more kiln furniture, so that the heat storage capacity of the kiln furniture is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel kiln furniture, in particular to a stable connection structure between kiln furniture with adjustable height of shed plates. Background technique [0002] Tunnel kiln is a kiln similar to a tunnel, which is made of refractory materials, thermal insulation materials and building materials, and is equipped with kiln cars and other vehicles. It plays a very important role, especially sanitary ware, such as toilets, washbasins, etc. One of the key transportation tools of tunnel kiln is the kiln car. The reliable and stable operation of the kiln car is very important for the safety of the product and the good transportation of the product out of the kiln. When the kiln car is working, it not only has to bear the weight of the product, but also bear the weight of the kiln furniture. Therefore, it is best to use lightweight shed plates and columns. The heat storage of lightweight materials is also relati...

AI Technical Summary

Problems solved by technology

When the kiln car is working, it must not only bear the gravity of the product, but also bear the weight of the kiln furniture. Therefore, it is best to use light weight for the shed and columns, and the heat storage of light materials is relatively small to avoid unnecessary waste of heat. Some tunnels The heat taken away by the kiln furniture is as high as 15% of the total heat, which is quite a lot. For large-scale enterprises, the economic benefits are greatly reduced, and the overweight kiln furniture will increase the labor intensity of the workers. Therefore, light-duty transformation is necessary

Another important point is that when firing different ceramic products, it may be necessary to adjust the height of the shelf, otherwise the temperature difference between the top and bottom of the preheating zone will be too large or the temperature will be uneven; the connection and placement of kiln furniture must also be considered , otherwise it may lead to uneven heating of the product and poor stability of the kiln car, which will further affect the appearance of ceramic products and product quality problems
