Problems solved by technology
The disadvantage of this air mixing method is that firstly, the added air will form resistance to the circulating air coming out of the kiln chamber, thus affecting the circulation effect, and secondly, the added cold air will cause the temperature of the product on this side to drop, increasing the inner cross section. Temperature difference, so that the uneven temperature will cause the product to deglue and crack

The invention discloses a rubber discharging structure of a pushed slab kiln circulation area. The rubber discharging structure of the pushed slab kiln circulation area comprises a kiln body, a kiln cavity, a heating cavity, an air inlet pipe, an exhaust pipe, an air circulating assembly and an air supply pipe, wherein the heating cavity is located at the lower end of the kiln cavity; the heatingcavity and the kiln cavity are located in the kiln body and communicate with each other; the exhaust pipe is located at the upper end of the kiln cavity; the air circulating assembly comprises a circulating fan and a circulating fan box; a fan impeller is located in the circulating fan box; the circulating fan box is located on the other side of the kiln cavity and communicates with the kiln cavity and the heating cavity; the air inlet pipe communicates with the heating cavity; the air supply pipe communicates with the fan box; and a clapboard for separating air from the kiln cavity and air from the air supply pipe is arranged in the fan box. According to the rubber discharging structure of the pushed slab kiln circulation area provided by the invention, supplied fresh air and the circulating air from the kiln cavity are adjusted to be mixed in the heating cavity, so that an impact effect on the kiln cavity through the supplied wire is reduced, the heat of the circulating air in the kiln cavity is uniformly spread, and a rubber discharging effect is improved; and through a way of mixing the supplied air, the kiln cavity achieves a stable effect.
Description
technical field [0001] The invention relates to sintering equipment, in particular to a glue-removing structure in the circulation area of a pusher kiln. Background technique [0002] The pusher kiln is an important equipment for sintering magnetic materials. In order to facilitate the molding of magnetic materials, a certain amount of organic binder (PVA) is often added to the magnetic material. These moisture and organic binders must be removed during the heating stage of sintering (this process is called debinding, mainly to discharge organic binders). The function of the circulation zone of the push plate kiln is to remove the moisture and organic binder in the billet by baking with hot air. According to the performance of the product, about 8 circulating fans are set in the general circulation area. The air entering the kiln cavity is heated by the heating wire, and then, driven by the circulation fan, it flows horizontally and evenly between the green compacts to ...
