An energy-saving kiln for recycling kiln bottom residue

Abstract

The invention relates to the field of kilns, in particular to an energy-saving kiln for recycling kiln bottom residues, including a sewage discharge box, a heating box is fixedly installed on the top of the sewage discharge box, a water pump is fixedly installed in the heating box, and the structure of the sewage discharge box A water tank is fixedly installed on the top, and a transmission mechanism is installed on the water tank. The bottom end of the transmission mechanism is inserted into the built-in round pipe. The top of the water tank is fixed with a support plate. A smoke exhaust pipe is installed, a residue collection box is fixedly installed on the top of the blowdown box, a furnace body is fixedly installed on the top of the residue collection box, a smoke pipe is fixedly installed on the top of the furnace body, and an insulation sleeve is fixedly sleeved on the outer wall of the furnace body. The hot water is discharged into the insulation jacket through the water pump. Since the insulation jacket covers the outer wall of the furnace body, the heat dissipation rate inside the furnace body can be reduced, the consumption of combustion raw materials can be reduced, and the energy-saving effect is greatly improved.

Description

technical field [0001] The invention relates to the field of kilns, in particular to an energy-saving kiln for recycling kiln bottom residues. Background technique [0002] A kiln refers to a furnace used for firing ceramics and sculptures or for fusing enamel to the surface of metal objects. When firing ceramics in a kiln, the embryos of the objects can be placed in the kiln, and then the burning materials are piled at the bottom of the kiln. During the combustion process, the combustion material can increase the internal temperature of the kiln and generate a large amount of heat to burn the utensil embryo. After the combustion material is burned, a large amount of residue will be produced. The residue is generally inorganic substances, mainly metal oxides, hydrogen Oxides and carbonates, sulfates, phosphates and silicates, a large amount of residues, especially residues containing heavy metal compounds, will cause great harm to the environment. In many countries, the inc...

Problems solved by technology

[0003] In the actual use of the traditional kiln, no heat preservation structure is installed outside the kiln, resulting in rapid heat loss in the kiln. More combustion materials need to be invested to ensure sufficient heat in the kiln, which increases the number of combustion materials. The amount of usage greatly reduces its energy-saving effect. Therefore, it is necessary to design an energy-saving kiln that recycles kiln bottom residue
