Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] The invention provides a top heating device for a stirred tank with a platinum channel, which suppresses the condensation of platinum-rhodium metal volatiles by increasing the ambient temperature of the top cavity of the stirred tank, and moves the cooling and condensing area upward to make it in a fixed position. Condensation is accumulated in the area, and the design of the structure here can regularly replace the brick material accumulated by the condensate to reduce the possibility of the condensate falling.

The invention provides a top heating device for a platinum channel agitation tank. The device comprises a heating device body which sleeves heating bricks at the top of the platinum channel agitationtank, one end of the heating device body is open, the other end of the heating device is closed, and the closed end is provided with installation holes; a cavity area is arranged between the heating device body and the heating bricks at the top of the platinum channel agitation tank; the heating device body is provided with a plurality of heating rods along a circumferential direction of the heating device body, one end of each heating rod is placed in the cavity area, and the other end of each heating rod penetrates through the heating device body and is placed outside the upper end of the heating device body; a heat insulating cover plate is detachably mounted in each installation hole, and each heat insulating cover plate is provided with a through hole. Through the structure, the temperature of an internal heater is preserved, the temperature of an internal cavity at the top of the agitation tank can be effectively increased to 1400 DEG C or above, and the condition for the condensation of platinum ruthenium volatile matter in the area can be reduced. At the same time, top condensates can be thoroughly removed regularly through the structure, and volatile condensates are prevented from being accumulated and falling into a glass liquid.
Description
technical field [0001] The invention belongs to the technical field of substrate glass manufacturing, and in particular relates to a top heating device of a platinum channel stirring tank. Background technique [0002] In the manufacturing process of substrate glass, the high-temperature molten glass melted by the furnace needs to flow through the platinum channel equipment, which is a very important area. Its main function is to clarify and homogenize the melted high-temperature molten glass. Since the platinum channel is made of platinum-rhodium alloy material as a whole, although the platinum-rhodium material has very stable high-temperature and corrosion-resistant capabilities, it is not suitable for long-term sustainability. Oxidation and volatilization of platinum and rhodium are unavoidable under working conditions. Especially in the stirred tank area, due to its special device structure, there will be an open area on the top that communicates with the outside world,...
