Problems solved by technology

However, the hardness of the molded wax billet is relatively poor, and soaking in a solvent will have a certain impact on the strength of the billet and cause damage to the molded billet; secondly, this method is not suitable for large-scale industrial applications; Higher, and it is necessary to deal with the solvent that absorbs the wax
These all affect the practical application value
[0005] Therefore, the current state of the art is that the wax discharge pollution problem of wax-molded ceramics has not been effectively solved for a long time, and has become a major hazard and problem for ceramic wax molds.

Embodiment 1

[0017] Embodiment 1: Referring to the accompanying drawings, the wax smoke produced by the wax discharge kiln (thermal wax discharge) is introduced into the wax discharge kiln or ceramic firing kiln by an induced draft fan to burn and burn part of the wax components, and then the smoke discharged from the combustion is (including wax smoke), through the closed water spray room 1, there are a number of partitions 2.1 and 2.2 arranged alternately in the water spray room, which divide the water spray room into multiple water spray channels, and the flue gas flows through each compartment. The channels between the plates meander and flow, and are sprayed by the spray head 3. The wax in the flue gas is solidified into a solid phase and separated from the flue gas due to spray cooling, so that most of the wax solidifies and falls on the water surface of the spray chamber for recovery, while the flue gas The dust in the air also sinks in the water due to the spraying. After spraying,...

Embodiment 2

[0018] Embodiment 2: As in Embodiment 1, for wax removal of small batches of ceramic products, the discharged wax can also be directly introduced into spray heat exchange and cooling heat exchange, and the above effects can also be achieved.

Abstract

The invention relates to a method for eliminating wax smoke during firing of ceramic products molded through doping wax. The method is characterized in that the wax smoke is produced by hot dewaxing, cooled by liquid sprinkling, and then discharged after being cooled below 28 DEG C through heat exchange. Wax and smoke in the discharged wax smoke can be simply, conveniently and completely separated, the wax is recovered in the form of solid wax, pollution and odour are eliminated, and the processing method is economic, simple, convenient and reliable. In particular, the wax smoke discharged by dewaxing is first introduced into and burnt in a furnace, therefore, not only can subsequent processing burden be reduced, but also combustion heat energy can be utilized. Wax smoke pollution can be stably eliminated with the method at low cost, the wax can be recovered, and the longstanding unsolved problem of wax pollution in the industry is solved.

Description

technical field [0001] The invention relates to a method for eliminating wax smoke pollution by shaping and firing ceramics mixed with wax. Background technique [0002] Ceramic wax molding is an important process in the production of ceramic products, especially for high-precision, special-shaped precision hot-press molding, with a long history. It is made by adding paraffin wax as a binder in the ceramic powder to make a fluid slurry and then hot die-casting to obtain a waxy molded body. When firing, it is first dewaxed by heat to make it into a volatile wax smoke in the ceramic body. excluded from the body. However, the wax fume discharged from dewaxing has a strong odor, which not only seriously pollutes the environment, but also has an impact on human health. Especially the discharged wax fume cools and solidifies and falls to cover the surface of vegetation, which will also affect the photosynthesis of plants and seriously cause plant death. [0003] Although in the ...
