Description

Technical Field

[0001] This utility model relates to the field of glass melt handling equipment, and in particular to a quartz ceramic handling ball. Background Technology

[0002] In the glass manufacturing process, a glass picker rod is needed to remove a suitable amount of molten glass from the crucible and place it into the forming mold. Existing glass picker rods include automated robotic arms and manual picker rods. Regardless of whether they are robotic arms or manual picker rods, their basic structure is the same, including the picker rod body and a picker ball at the end of the body. The rod body is generally made of metal (e.g., steel); the picker ball is generally made of quartz ceramic, which is heat-resistant and spherical in shape. The two are connected by threads. However, because the picker ball withstands high temperatures, and is directly connected to the metal picker rod, the rod's rapid heat dissipation means it quickly absorbs the heat from the picker ball, causing the ball to cool down rapidly and potentially leading to crystallization of the molten glass on it. In addition, the picking ball and the picking rod are connected by threads. After the picking ball picks up the molten glass, the molten glass can easily wet the connection between the picking ball and the picking rod because the picking ball is a sphere. When the picking rod needs to be replaced, it is difficult to separate the picking rod from the picking ball.

[0003] Chinese patent CN108546135A discloses a quartz ceramic picking ball. By providing a vacuum chamber between the picking ball and the inner liner, heat on the outer surface of the picking ball can be isolated, preventing the picking rod connected to the picking ball from absorbing excessive heat. However, this patent also has certain drawbacks. For example, the process of reprocessing the inner liner inside the picking ball is cumbersome and difficult. Furthermore, this patent cannot solve the problem of the picking rod being difficult to replace after the glass melt wets the connection between the picking ball and the picking rod. Utility Model Content

[0004] The purpose of this invention is to provide a quartz ceramic material handling ball.

[0005] The innovation of this utility model is as follows: the quartz ceramic tube can prevent the picking ball from being directly connected to the picking rod, and the quartz ceramic tube can prevent the picking ball from cooling down too quickly, thereby preventing the glass melt from crystallizing; the baffle skirt can prevent the glass melt from directly wetting the connection, and the picking rod / quartz ceramic tube can be easily replaced.

[0006] To achieve the aforementioned objectives, the technical solution of this utility model is as follows:

[0007] A quartz ceramic material-carrying ball includes a material-carrying ball and a quartz ceramic tube. The material-carrying ball is elliptical, with one pointed end along its long axis serving as a material-carrying end, and a connecting hole machined at the center of the other pointed end. The inner wall of the connecting hole is provided with internal threads. The quartz ceramic tube is closed at both ends, forming a vacuum cavity in the middle. A connecting post is respectively provided at the center of the closed ends of the quartz ceramic tube, and the connecting post is provided with external threads. One connecting post is threadedly screwed into the connecting hole of the material-carrying ball, and the other connecting post is connected to a material-carrying rod.

[0008] Furthermore, an outwardly extending baffle skirt is provided on the outer edge of the connecting hole of the picking ball.

[0009] Furthermore, the baffle skirt and the picking ball are integrally formed, and the outer edge diameter of the baffle skirt is slightly larger than the length of the short axis of the picking ball.

[0010] Furthermore, the length of the quartz ceramic tube is not less than 3 / 4 of the length of the major axis of the picking ball.

[0011] The beneficial effects of this utility model are:

[0012] First: A quartz ceramic tube is installed between the picking ball and the picking rod, and the two ends of the quartz ceramic tube are sealed to form a vacuum cavity in the middle, which facilitates heat insulation and avoids the picking ball from being directly connected to the picking rod. The quartz ceramic tube can prevent the picking ball from cooling down too quickly, thereby preventing the glass melt from crystallizing.

[0013] Second: Installing a quartz ceramic tube can also prevent the material handling rod from easily deforming when subjected to high heat.

[0014] Third: The shape of the picking ball is set to oval, with a pointed tip, which makes it easy to pick up materials and control the amount of materials picked up. An outward-extending baffle skirt is set on the outer edge of the connecting hole of the picking ball to prevent the molten glass from directly wetting the connection. It also makes it easy to replace the picking rod / quartz ceramic tube. Attached Figure Description
