The invention discloses a kiln for removing wax by utilizing waste heat. The kiln comprises a kiln body and a conveying mechanism. By arranging a wax removing chamber, the waste heat of a sintering chamber can be directly transferred into the wax removing chamber through a first inner wall, so that the internal temperature of the wax removing chamber is increased, and heat supplied to the wax removing chamber through external energy is reduced. Compared with an existing kiln for transferring heat energy in a sintering section to a wax removing section by utilizing gas, the kiln has the advantage that the efficiency of heat conduction by utilizing solids is higher. Moreover, although the waste heat can be utilized to a certain extent in the prior art, the heat energy of the sintering section cannot be prevented from being diffused to the external space through the outer wall, a semi-wrapping mode is adopted, the heat energy diffused through the outer wall can be fully utilized, and therefore the utilization efficiency of the waste heat is higher. Moreover, according to the same principle, a cooling chamber can also utilize the waste heat of the sintering section, so that the effectthat cooling can be carried out step by step and in a controllable mode without utilizing external energy for heating is achieved.
Description
technical field [0001] The invention relates to the technical field of wax-discharging kiln, in particular to a kiln which utilizes waste heat to discharge wax. Background technique [0002] Ceramic molding includes various processes such as injection molding, dry powder molding and hot die casting molding. Among them, hot die casting molding can form products with complex shapes, and has the advantages of simple process and low mold finished product, so it is widely used. When using the hot die casting molding process, the ceramic mud must be dewaxed before sintering. [0003] The existing wax removal process usually uses combustion or electric heating to directly heat the kiln, so that the ceramic mud body in it is heated to heat up, thereby realizing wax removal. On the one hand, a large amount of energy is consumed for combustion or electric heating for wax removal, and on the other hand, waste heat during sintering is dissipated to the outside space and is not effectiv...
