Abstract
A kind of energy-saving furnace for baking cadmium red glaze porcelain, it comprises body of heater, and described body of heater is made of shell, heat-insulation layer and refractory layer, and the refractory layer inwall is equipped with heat generating member, and burner hearth bottom is placed with movably push pedal, is placed with at least two dividing plates in the push pedal.Because burner hearth is placed with dividing plate, can reduce the mobile speed of hot-air in the stove, reduce the exchange capacity of cold and hot air, thereby can cut down the consumption of energy energy savings.According to measuring and calculating, the energy-conservation 10%-18% that reaches.
Description
Technical field
The present invention relates to a kind of kiln of fire porcelain, especially relate to a kind of energy-saving furnace for baking cadmium red glaze porcelain.
Background technology
The present kiln (as pushed bat kiln or tunnel cave) of baking cadmium red glaze porcelain, more than 1200 ℃ during the high-temperature firing cadmium red glaze porcelain, because the hot-air speed that flows is quite fast in the burner hearth, cold and hot air exchange amount is big, makes energy utilization rate low, and energy consumption is big.
Summary of the invention
The objective of the invention is to overcome the defective of existing pushed bat kiln or tunnel cave existence, a kind of kiln of the baking cadmium red glaze porcelain that can significantly cut down the consumption of energy is provided.
The objective of the invention is to be achieved through the following technical solutions: comprise body of heater, described body of heater is made of shell, heat-insulation layer and refractory layer, and the refractory layer inwall is equipped with heat generating member, and burner hearth bottom is placed with movably push pedal, is placed with at least two dividing plates in the push pedal.
Distance between dividing plate and the dividing plate generally can be 680mm-1700mm (preferred 1020mm); The distance of dividing plate top and roof of the furnace generally can be 50mm-70mm (preferred 60mm), and the distance of dividing plate and furnace wall, both sides can be respectively 40mm-50mm (preferred 45mm).Block board thickness generally can be 40-60mm (preferred 50mm).Distance between dividing plate and the dividing plate is long, and baffle dimensions is too small, all can influence energy-saving effect; But the distance between dividing plate and the dividing plate is too short, can influence the porcelain semi-finished product and place; Baffle dimensions is excessive, can influence temperature homogeneity in the burner hearth.
For ease of placing, the dividing plate base can be made into the cross shape.
Described dividing plate is preferably the dividing plate that alumina silicate fibre is made.
Dividing plate is set in burner hearth, can reduces the mobile speed of hot-air in the stove, reduce the exchange capacity of cold and hot air, thereby can cut down the consumption of energy energy savings.According to measuring and calculating, the energy-conservation 10%-18% that reaches.
