Abstract
The invention discloses an all-electric melting glass kiln for melting and manufacturing a medicinal glass tube, which comprises a melting tank, a main melting electrode, a homogenizing electrode, a throat and an ascending channel, the melting tank comprises a melting tank upper tank, a transition layer and a melting tank lower tank, the melting tank is divided into the upper tank and the lower tank through the transition layer, and the main melting electrode and the homogenizing electrode are arranged in the ascending channel. The upper tank is mainly a molten glass melting and bubble discharging area, and the lower tank of the melting tank is a molten glass homogenizing and bubble absorbing area. The lower portion of the melting tank is connected with the ascending channel through the throat, and glass liquid is conveyed to a forming area. The main melting electrode is arranged on the tank wall of the upper tank of the melting tank, and the homogenizing electrode is arranged on the furnace bottom of the lower tank of the melting tank. According to the invention, electricity is input into molten glass by an electrode, and high temperature is generated through resistance heating of the glass, so that the glass is vertically molten, and a rapid, uniform and pollution-free molten state is achieved.
Description
technical field [0001] The invention relates to the technical field of glass furnaces, in particular to an all-electric melting glass furnace for melting and manufacturing medicinal glass tubes. Background technique [0002] 5.0 The coefficient of expansion of neutral medicinal glass tubing is (4.8-5.1)×10 -6 K -1 . Some in China also call it 5.0 neutral borosilicate glass or grade A material, and 5.0 medicinal glass tubes are mainly used in the packaging industry of medicines, such as vaccine bottles. Its main features are: long-term contact with liquid medicine and blood will not cause sedimentation, will not cause changes in pH value, and has excellent chemical and thermal stability. [0003] Cause pass rate is low, the main reason that product quality is unqualified is that the quality of the molten glass that glass kiln melts is unqualified. The key to glass melting is the equipment for melting glass, the glass furnace. Therefore, how to provide an all-electric mel...
