Abstract
The utility model discloses a magnetic grid device for a TFT (thin film transistor) liquid crystal glass melting charging opening. The magnetic grid device comprises a magnetic grid frame and magnetic bars arranged on the magnetic grid frame, wherein the magnetic bars are distributed on the magnetic grid frame in the manner of different interlayer structures. The cross section of the magnetic grid frame is circular. The magnetic grid device with a certain shape is manufactured, and the magnetic grid device is placed right above the charging opening, so that a mixture flows into a storage bin from a netty structure of the magnetic grid device, and the effect of magnetic separation can be achieved; and metal impurities in the mixture, i.e., the irons, are intercepted, so that the content of the metals in the mixture, i.e., the irons, can be reduced to be lowest.
Description
Technical field
The utility model belongs to TFT glass manufacturing area device, and particularly a kind of TFT liquid-crystalline glasses melts the magnetic grid device that charging opening uses.
Background technology
In the manufacturing of TFT glass, glass is in melting process, the metallic impurity such as iron class not only can make platinum channel corrode and accelerate, shorten the platinum channel life-span, and electrolysis generation air blister defect can occur, so that should strengthen passage safeguards, need lengthen settling time simultaneously, or temperature of glass liquid is raise, increasing the method such as finings in the raw material overflows gas from glass metal, but the condition of high temperature is easily accelerated erosions such as the anti-materials of tank furnace fining end, increase the defectives such as method increase production cost such as finings in the raw material, in known prior art, basic adopt the content of the metallic impurity such as iron class in the raw-material specification of control and in the glass cullet system, increase magnetic separator prevent this type of impurity, but whether the metals content impurity such as iron class low still without guarantee in the compound.
The utility model content
For overcoming above the deficiencies in the prior art, the utility model provides a kind of TFT liquid-crystalline glasses to melt the magnetic grid device that charging opening uses, the magnetic grid device that has definite shape by making, place it in directly over the charging opening, make compound in its reticulated structure, flow into feed bin, reach the magnetic separation effect, the metallic impurity such as iron class in the compound are tackled, make in the compound metal content such as iron class be down to minimum.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of TFT liquid-crystalline glasses melts the magnetic grid device that charging opening uses, and comprises the magnetic grid framework, and be arranged on the bar magnet on the magnetic grid framework that described bar magnet distributes as net shape on the magnetic grid framework.
Further, in the described device, magnetic grid framework cross section is rounded, and its diameter is 340-360mm.
Further, in the described device, be latticed bar magnet and be between different layers structure distribution on the magnetic grid framework.
Employing melts charging opening at the TFT liquid-crystalline glasses magnetic grid device is set, in melting adding compound process, carry out a magnetic separation effect, because the bar magnet of magnetic grid device own has extremely strong magnetic, place it in directly over the charging opening, magneticly elect ferrous metal impurity, make in the compound ferrous metal impurity be down to minimum.Make the metallic impurity such as a small amount of iron class contained in the compound by magnetic separation out, guarantee the cleanliness factor of compound, reduce the generation of bubble, ensure the safety of platinum channel.
Description of drawings
Fig. 1 is the utility model magnetic grid apparatus structure synoptic diagram.
Wherein: 1 is the magnetic grid framework; 2 is bar magnet.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Referring to shown in Figure 1, this TFT liquid-crystalline glasses melts the magnetic grid device that charging opening uses, and comprises magnetic grid framework 1, and be arranged on the bar magnet 2 on the magnetic grid framework 1 that wherein, bar magnet 2 distributes as net shape on magnetic grid framework 1.The rounded structure in the cross section of this magnetic grid framework 1, its diameter is greater than 340mm, at 340-360mm.And be latticed bar magnet 2 and be between different layers structure distribution on magnetic grid framework 1.
This magnetic grid device is enabled, and makes its operating area be the magnetic separation state, and magnetic separation is to utilize magnetic force to remove the method for magnetic metal impurity in the oil plant, and the application of magnetic separation then is the magnetic contrast that utilizes various ores or material, the process that sorts under magnetic force and other effects.During use, this magnetic grid device directly is placed on directly over the charging opening, make compound in its reticulated structure, flow into feed bin, superpower magnetic force by itself bar magnet, reach the magnetic separation effect, make in the compound metallic impurity such as iron class be blocked, it is less than charging opening interior region width to install its diameter dimension, is easy to dismounting, installs.And it is minimum that the metal content such as iron class is down to, and ensured the security of platinum channel and the minimizing of air blister defect.
Above embodiment only is used for explanation the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that does not break away from spirit and scope of the present utility model; can also make a variety of changes and be out of shape; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection reason claim of the present utility model limits.
