Description

Glass liquid stirrer

Technical Field

The utility model relates to a glass liquid agitator belongs to support plate glass processing field.

Background

The homogenization of the molten glass is realized by mutual diffusion and dissolution among melts with different components, rising and overturning of bubbles in the molten glass, convection of the molten glass and the like. The method is mainly characterized in that a part with more components in a melt moves to a part with less components by molecular diffusion movement, thereby eliminating the stripes in the glass and promoting the glass liquid to be uniform in chemical composition. Since diffusion in viscous media is particularly slow, it takes a long time to pass, and the homogenization quality efficiency is often not high. In order to accelerate the homogenization process, a mechanical stirring method is usually adopted to continuously divide the non-uniform area and the thick stripes in the molten glass into very thin and short stripes, so that the contact surface of the thin and short stripes is enlarged, mutual dissolution and diffusion between the molten glass and the stripes are facilitated, and the stripes gradually disappear or decrease.

At present, most of glass liquid stirrers are spiral or rectangular blades, the utility model patent CN202021039744.1 discloses a spiral molten glass stirring rod, the patent CN202020531884.4 discloses a molten glass stirring rod with rectangular blades, and both the spiral and rectangular blade stirring rods have the problem of uneven stirring due to small stirring coverage area; if under the equal prerequisite of stirring area of coverage, the contact surface of spiral and rectangular blade and molten glass liquid is big for the moment of torsion that the puddler bore and the effort that the agitator bore all can increase, and the high temperature of molten glass liquid also can weaken the intensity of puddler simultaneously, leads to often appearing the circumstances that the puddler splits and agitator life shortens in the use as a result.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a glass liquid agitator, stirring effect is good, can prolong the life of agitator and agitator.

The glass liquid stirrer comprises a stirrer shaft and stirrer blades which are fixedly communicated with the stirrer shaft, wherein the stirrer blades are of a frame structure consisting of a transverse stirring rod and a longitudinal stirring rod, the transverse stirring rod is vertically communicated with the stirrer shaft, and the longitudinal stirring rod is parallel to the stirrer shaft and is communicated with the transverse stirring rod; the stirrer shaft and the stirrer blade stirring rod are internally provided with hollow cavities which are mutually communicated, a cooling liquid pipe is arranged in each cavity, a cooling liquid return sleeve is arranged on the outer side of each cooling liquid pipe, and the cross sections of the cooling liquid pipe and the cooling liquid return sleeve are preferably concentric circles.

The number of the stirrer blade groups can be set to 1-4, and the included angles of the adjacent stirrer blades are preferably controlled to be equal.

The number of the transverse stirring rods of the single group of the stirrer blades can be 2-4, and the distance between every two transverse stirring rods is preferably controlled to be equal.

The longitudinal stirring rods of the single group of stirrer blades can be arranged in 2-6, preferably, the longitudinal stirring rods are symmetrically arranged at two sides of the stirrer shaft, and each side can be provided with 1-3.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the stirring effect is good, and the stirring is more even. The utility model discloses a glass stirrer passes through the frame construction of stirring rod, and increase stirring area refines cutting and intensive mixing to molten glass liquid, makes gaseous composition wherein become the bubble after fully fusing and flees, improves the degree of consistency and the glass quality after happy molten glass stirs.

2. The service life of the stirrer and the stirring barrel is long. The utility model discloses a glass stirrer is little with the contact relative area of molten glass liquid, and the moment of torsion that the agitator bore and the effort that the agitator bore reduce, and are equipped with the coolant liquid pipe in the agitator, are favorable to maintaining the high temperature strength of agitator to the life of stirring rod and agitator has been prolonged.
