Description

TECHNICAL FIELD

[0001] The utility model relates to touch screen glass panel production technical field, concretely relates to a touch screen glass strengthening furnace convenient to clean. BACKGROUND

[0002] Touch screen glass panel is one of the core components of realizing touch interaction in modern electronic equipment, and is widely used in smart phones, tablet computers, ATM machines, industrial control panels and other equipment. In the subsequent processing process of touch screen glass panel, it needs to be chemically strengthened, and the chemical strengthening of touch screen glass (also known as ion exchange strengthening) is a key process for improving the mechanical strength and damage resistance of glass surface by changing the chemical composition.

[0003] As shown in Figure 1 The existing strengthening furnace includes a furnace body and a heating pipe installed on the inner side of the furnace body. The touch screen glass tempering cage is placed in the strengthening furnace, and then the strengthening liquid is added. The strengthening liquid is heated by the heating pipe for strengthening treatment. When cleaning the waste liquid, only the centrifugal pump can be used for extraction. However, the liquid extraction is not complete (for example, the uneven ground causes the furnace body to tilt slightly, and the strengthening liquid attached to the side wall of the furnace body has low pumping efficiency), which causes residual liquid to accumulate at the bottom of the furnace body. Manual cleaning with a medicine spoon is required, which is dangerous for human operation at high temperature. In addition, the residual liquid at the bottom is not completely cleaned, which causes differences in the proportion of new strengthening liquid, resulting in unstable chemical strengthening process. UTILITY MODEL CONTENT

[0004] The utility model intends to provide a touch screen glass strengthening furnace convenient to clean, so as to solve the problem of incomplete residual liquid cleaning in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0006] A touch screen glass strengthening furnace convenient to clean, including the furnace body and the drain pipe provided with the valve, the inside of the furnace body is fixedly provided with the support frame, the bottom of the furnace body includes the left inclined plane and the right inclined plane which are inclined downward to the drain pipe, the bottom of the left inclined plane and the right inclined plane surrounds the drain pipe and is communicated; the width of the left inclined plane is greater than that of the right inclined plane, the inclination of the left inclined plane is smaller than that of the right inclined plane, and the highest point of the right inclined plane is higher than the lowest point of the left inclined plane.

[0007] The working principle and beneficial effects of the utility model are as follows:

[0008] The solid salt crystal is heated, and the solid salt crystal is completely melted into liquid state. The glass tempering cage filled with the glass to be chemically strengthened is placed in the salt liquid. The support frame supports the glass tempering cage in the furnace body in a horizontal state and is completely immersed in the high-temperature molten salt liquid. After the chemical strengthening is completed, the high-temperature strengthening salt liquid reaching the service life needs to be completely replaced. The centrifugal pump is placed in the salt liquid for extraction. When the liquid level cannot be extracted any more, the centrifugal pump cannot work and is taken out. The valve is opened, and the salt liquid flows out of the furnace body through the drain pipe.

[0009] When the internal salt liquid is discharged to a certain extent, the residual salt liquid on the inner wall of the furnace body falls downward on the left and right inclined surfaces. Since the width of the left inclined surface is greater than that of the right inclined surface, and the slope of the left inclined surface is smaller than that of the right inclined surface, the gentle slope of the left inclined surface prevents the salt liquid from splashing or locally remaining due to excessive speed in the initial stage of flow. The slope of the right inclined surface is large, so that the impact force of the flowing salt liquid on the left inclined surface can be buffered to prevent the salt liquid from splashing. The highest point of the right inclined surface is higher than the lowest point of the left inclined surface, so that after the liquid level is lowered, the remaining salt liquid is concentrated to the drain pipe to realize complete emptying. In this way, the residual liquid in the furnace body can be cleaned.

[0010] The present application can replace the manual cleaning of residual liquid in the prior art, reduce the risk coefficient of working at high temperature, and efficiently and completely clean the residual liquid in the furnace body, so that the proportion of new salt liquid is more accurate, and the tempering stability of touch screen glass is better.

[0011] Further, the left inclined surface, the right inclined surface and the drain pipe are wrapped with heat insulation cotton. The heat insulation cotton is used for heat preservation of the bottom of the furnace body and the drain pipe.
