Description
Technical Field
The invention relates to the technical field of glass tube production, in particular to a heat exchange rotary tube method.
Background
The neutral borosilicate glass tube for medical use is produced by Danna shaping method, its shaping principle is that glass liquid is dropped onto the rotary tube made of refractory material through the material nozzle, and then is shaped by blowing and drawing. The rotating tube needs to be replaced after a period of use due to erosion of the molten glass.
As shown in fig. 1 and 2, two forming lines of an existing kiln are respectively arranged on two sides of the kiln 101, each forming line comprises a dane machine 201, a muffle 202 and a forming chamber 203 which are sequentially arranged from back to front, the dane machine 201 is provided with a rotatable machine head, a shaft sleeve is arranged on the machine head, the rear end of a large shaft 204 is in butt joint with the machine head shaft sleeve of the dane machine 201, the front end of the large shaft 204 is sleeved with a rotating pipe 205 and is inserted into the muffle 202 from the rear end of the muffle 202, the rotating pipe 205 is positioned in a hearth of the muffle 202, the dane machine 201 and the muffle 202 are both arranged on a lifting platform 206, so that the front end of the muffle 202 is flush with the rear end of the forming chamber 203, and the rear end of the forming chamber 203 is in movable butt joint with the front end of the muffle 202. Glass liquid in the kiln 101 flows into the working pool 103 through the liquid flow hole 102, flows into the muffle furnace 202 through the two platinum channels 104 respectively, is dripped onto the rotary pipe 205 through the material nozzle, and is blown into the forming chamber 203 to be formed into a glass pipe.
The two forming line production lines of the kiln generally adopt a post-change rotary pipe scheme that the Danner machine 201 withdraws and changes the rotary pipe 205. A tube changing fixing bracket 301 is arranged on one side of the two lifting platforms 206 away from the kiln 101, and an electric hoist 302 and a preheating furnace 303 are arranged on the tube changing fixing bracket 301 and used for heat exchanging the rotary tube. The method for heat exchanging the rotary pipe of the two kiln forming line production lines comprises the following two steps: step one, referring to fig. 3, the danner 201 is retracted a certain distance, so that the large shaft 204 and the rotary pipe 205 are all withdrawn from the muffle 202; step two, referring to fig. 4, the head of the Danner machine 201 is rotated by 90 degrees, so that the large shaft 204 and the rotating tube 205 are rotated to the position of the tube changing fixing support 301, and the heat exchange rotating tube is completed through the electric hoist 302 and the preheating furnace 303. After the replacement, the machine head of the Danner machine 201 rotates reversely and moves forwards to reset, and the working state can be restored.
In order to save energy, reduce consumption and improve market competitiveness, a kiln multi-line is a development trend of a boron-silicon pull tube production line in the future, and at present, no production line of boron-silicon in a kiln four-line adopting a Danner method is adopted in China, and the main reason is that when a production process of four forming lines of a kiln is adopted, if a conventional post-change rotary tube scheme is adopted for the two middle forming lines, in order to enable enough space to exist behind the Danner machine 201, the length and the width of a working pool 103 are required to be increased sharply, and the quality of glass liquid of each forming line is inevitably uneven, so that the quality of products is affected. Therefore, a kiln four-forming line production line cannot adopt a conventional post-change rotary tube scheme because there is not enough space behind the Danner machine 201 of the middle two forming lines. Therefore, a need exists for a heat exchange rotary tube solution suitable for a kiln four-wire forming line.
