The invention discloses a device and a method for discharging wax in preparation process of aluminum oxide ceramic tubes. The device comprises a support frame, a furnace body, a heating device, a metal disc and a controller. The furnace body is supported by the support frame, a support for placing the metal disc is arranged in the furnace body, a plurality of holes for placing green bodies are arranged on the metal disc, the size of each hole is identical to the length of the tail tube portion of each green body inserted into each hole, the cavity portion of each green body is placed on each hole stably, and a distance between every two holes is a 10-20mm distance between every two placed green bodies. An air inlet is arranged at the bottom of the heating device and is communicated with the furnace body, the controller and an air exhaust device are further arranged above the furnace body in sequence, and a wax receiving disc is arranged under the furnace body and fixed on the support frame. The device and the method for discharging the wax in preparation process of the aluminum oxide ceramic tubes adopts hot-air wax discharge to replace drying oven wax discharge, hot air gradually performs heating from bottom to top, the temperature is even, wax discharge is thorough, and quality and pass percent of products are improved. The device is simple in structure, convenient to operate and short in wax discharging time, improves the production efficiency and facilitates scale production.
Description
technical field [0001] The invention relates to a device and method used in the preparation process of alumina ceramic tubes, in particular to a device and method for removing wax in the process of preparing alumina ceramic tubes. Background technique [0002] Ceramic metal halide lamp is one of the most advanced energy-saving light sources in the world today. It has the advantages of high luminous efficiency, long life, good color rendering, and compact structure. It is widely used in airports, docks, roads, shopping malls, hotels and other indoor areas. External lighting is one of the most ideal light sources. The shell (alumina ceramic tube) of the ceramic metal halide lamp is a key component for making a ceramic metal halide lamp. The one-piece alumina ceramic tube of the grouting method also limits large-scale production due to the difficulty in controlling the volume of the cavity, poor dimensional consistency, and low efficiency. The manufacturing process of one-pie...
