Annealing furnace for production of pharmaceutical glass bottles

Abstract

The invention discloses an annealing furnace for production of pharmaceutical glass bottles, comprising an outer casing, falling conveyor belts, a conveyor-belt fixing plate and a feeding motor, wherein the outer walls of the two sides of the outer casing are each fixed obliquely equipped with two falling motors, and the power output ends of the falling motors are fixedly mounted in the outer casing; the power output ends of the falling motors are fixedly equipped with falling drums, and the exteriors of the falling drums are movably sleeved by the falling conveyor belts; the outer surfaces ofthe falling conveyor belts are fixedly connected with punties; and the outer wall of one side of the outer casing is fixedly provided with a liquefied gas tank, the top of the liquefied gas tank is fixedly equipped with gas combustion nozzles via pipes, and the gas combustion nozzles are fixedly arranged at the inner walls of two sides of the outer casing. According to the invention, a method ofvertical annealing is adopted, during a falling process, the temperature of glass is gradually reduced, so that annealing is achieved, at the same time, the land occupation area of the annealing furnace is saved, and the processing process for annealing glass products in a small space is realized.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to an annealing furnace for the production of glass pharmaceutical bottles. Background technique [0002] The glass annealing furnace is mainly used for primary annealing of daily-use glass and lighting glass such as glass bottles and cups, and secondary stress relief annealing after reprocessing. The total length of the furnace body is 6-40 meters, and the maximum operating temperature is 650°C. [0003] However, the traditional glass annealing furnace has some disadvantages during use, such as: [0004] The traditional glass annealing furnace is generally long in order to moderate the temperature change of the glass, so that the glass can be fully cooled in the annealing furnace. However, due to the large size of the traditional annealing furnace, it is time-consuming to install and occupies a large area. Larger and more expensive. Contents of the invention [0005] T...
