Device for directly drawing helical circular quartz tube by continuous-melt method and drawing method

Abstract

The invention discloses a device for directly drawing a helical circular quartz tube by a continuous-melt method and a method for drawing the helical circular quartz tube by the device. The device comprises a rotary winding which is arranged below a discharge hole of a continuous-melt furnace; the rotary winding machine is fixed on a support plate through a support frame; a left and right movement mechanism for driving the rotary winding machine to move left and right is arranged at the lower part of the support plate; a front and back movement mechanism is arranged at the lower part of the left and right movement mechanism; the lower end of the front and back movement mechanism is arranged on a lifting mechanism; the rotary winding machine comprises a rotary drum; the rotary drum is fixed on a rotating shaft; the rotating shaft is connected with a drive motor through a drive device; a quartz tube pressing tube is arranged on the rotary drum; a quartz tube descending tractor is arranged between a discharge hole of the continuous-melt furnace and the rotary winding machine; and a quartz tube cutter is arranged between the quartz tube descending tractor and the rotary winding machine. The helical circular quartz tube is formed by molding once; secondary processing is removed; an energy source is saved; time and labor are saved; and the helical circular quartz tube is even in screw pitch and stable in quality.

Description

technical field [0001] The invention relates to a device for directly drawing a spiral annular quartz tube by a continuous melting method; the invention also relates to a method for preparing a spiral annular quartz tube by using the aforementioned device. Background technique [0002] At present, the continuous melting method at home and abroad is generally used to straighten the tube by a tube drawing machine, and cut it into different lengths according to the needs of users. If it is to be made into a spiral ring, it needs to be heated twice with hydrogen and oxygen, and then processed by a shaping mold. . The disadvantage of this technology is that secondary processing is required, which requires high energy consumption and long time consumption; and due to the temperature and time of secondary heating, the softening degree of the quartz tube, etc., it is easy to cause irregular spiral rings, uneven spacing, and uneven tube diameters. , Inconsistent high pressure resist...
