Description

Glass recycling system

This creation is about glass recycling, especially a glass recycling system that can recycle and reuse the glass substrate of a display to achieve environmental protection and energy saving and carbon reduction effects.

According to the report, Liquid Crystal Display (LCD) has replaced traditional cathode ray tubes and become the mainstream due to its lightness and thinness. Therefore, it can be seen that the overall demand for LCDs in the world has increased significantly year by year, but this has resulted in a large number of discarded LCDs.

The sources of discarded LCD monitors are mainly divided into defective products on the panel factory line and old or damaged waste products on the market. However, due to the lack of complete and effective resource recycling and remanufacturing technology, the current discarded LCD monitors are mainly disassembled and sent to landfills for burial. However, traditional landfilling not only fails to reduce waste, but also has the risk of environmental pollution. In addition, due to the special material of the glass substrate of the discarded LCD monitor, it is known that the discarded glass substrate cannot be recycled to the traditional flat glass melting manufacturing plant. Moreover, due to the expansion coefficient of the discarded glass substrate, it cannot be sent to the container glass melting manufacturing plant for recycling.

Therefore, how to improve the above deficiencies is the technical difficulty that the creator of this case wants to solve.

Therefore, in order to effectively solve the above problems, the main purpose of this invention is to provide a glass recycling system that can recycle and recycle the discarded glass substrates of discarded displays to achieve environmental protection and energy saving and carbon reduction effects.

First, please refer to Figure 1, which is a schematic diagram showing the system of the glass recycling system of the present invention, wherein the glass recycling system 1 includes a crushing device 11, a screening and containing device 12, a dissolving and containing device 13, a magnetic screen device 14, a melting device 15, and a platinum screen device 16.

Please refer to Figure 2, which is a schematic diagram showing the implementation of the glass recycling system of the invention. When the glass recycling system is used, at least one waste display is first obtained. In this embodiment, the waste glass recycling method is mainly to recycle the alkali-free glass of the TFT display, and the liquid crystal contained in the waste display is first extracted and recycled, and the internal polarizer is removed, and the remaining waste display components are used to know the glass type using the production history mark to obtain a waste glass substrate 2 of the waste display.

Then the waste glass substrate 2 is crushed by the crushing device 11, wherein the crushing device 11 can be a high-speed crusher or a vibration crusher, and a glass crushed object 21 is obtained, and the glass crushed object 21 is placed in the screening container 12, wherein the screening container 12 can be an optical screening machine or a vibration screening machine, and the screening container 12 is filled with water, and the glass crushed object 21 is screened out of non-glass substances by the buoyancy of the material density of the water, and then the screened glass crushed object 21 is placed in the dissolving container The dissolving and containing device 13 can be a device using an acid leaching method or an induction furnace, and the dissolving and containing device 13 is filled with concentrated hot sulfuric acid liquid, and the screened glass pulverized material 21 is dissolved by the concentrated hot sulfuric acid liquid to remove the metal film component and the organic component to obtain a glass pulverized body 22, and the glass pulverized body 22 needs to be washed with water to remove the concentrated hot sulfuric acid liquid, and the washed glass pulverized body 22 is removed of magnetic metal materials by the magnetic grating device 14, wherein the magnetic grating device 14 can be a drum separator or a magnetic separation belt.

The glass crushed body 22 is then placed in the melting device 15. The melting device 15 is heated to 1600 degrees C and maintained at this temperature for more than 24 hours to melt the glass crushed body 22 and add mineral raw materials at the same time, so that the glass components of the glass crushed body 22 are uniformly dissolved and mixed.
