Description

Recycling method for discarded foil glass

The invention relates to a recycling processing method, in particular to a recycling processing method for waste film glass.

Inspect, the glass produced by the general production line, after the cold, needs to be finished after the quality control, cutting, storage, etc., so that the so-called "stock original film" can be formed, and the original stock can be re Cutting, storing or using. Therefore, after the glass is finished, a film is attached to the upper and lower sides of the glass before being cut. Generally, the glass substrate is attached. Gum film traditionally uses PET as the base of the protective film. The adhesive used between the film and the glass can be Silicone, Acrylic, Acrylic, etc., thereby protecting the glass. It will not be scratched or rubbed against each other; therefore, in the process of cutting and forming the original piece, a lot of undercuts (ie, discarded glass after cutting) are formed, and the waste glass is also The film is attached, and in the past, the waste glass was recycled and re-fused, and the waste glass was effectively recycled.

Referring to FIG. 1, the conventional recycling processing method 1 has a stacking step 11, a stripping step 12, a processing step 13, and the like; wherein the stacking step 11 accumulates a waste glass having a film to a certain amount so as to be In the film removing step 12, a chemical solvent 121 is used for the dissolution treatment, that is, the chemical solvent 121 is used to break the chemical adhesion between the waste glass and the film, so that the film is peeled off or directly eroded, and then the subsequent steps are performed. Therefore, the waste glass is effectively recycled and then recycled (ie, the process step 13).

However, in the above-mentioned operation of the film removing step 12, although the chemical solvent 121 can be used to quickly achieve a better film removing effect, in the film removing process, it is necessary to have different types depending on the type of the film. The chemical solvent 121 is used, and the amount of the chemical solvent 121 is fixed, and the cost is high, and the waste glass is not only concentrated until a fixed amount, but the chemical solvent 121 is added to be uniformly removed. The film treatment is such that the film removal step 12 cannot be continuously performed in an uninterrupted manner due to the problem of the amount of the waste glass concentration, and the chemical solvent 121 remains on the waste glass after the film is removed. The amount of the residue depends on the amount of the use, and the more the amount used, the more the residual amount, so that after the solvent 121 is used, another cleaning step of removing the chemical solvent 121 is required. In order to form a clean sample with no residue on the surface of the discarded glass, the method can be used for subsequent recycling, and the process is cumbersome and inefficient, and the time for controlling the film removal operation cannot be effectively unified, and It is even more necessary to have a large area to stack and store the waste glass, and the centralized processing operation will be carried out in the future. Therefore, it is not easy to carry out the recycling operation of the discarded film glass.

In view of this, there is a further research method 2 for recycling another foil glass. Referring to FIG. 2, the method sequentially includes a stacking step 21, a stripping step 22 and a processing step 23; wherein the stacking step 21 And the processing step 23 is the same as the previous conventional processing, and will not be described in detail; however, in the film removing step 22, the waste glass is treated in a combustion manner by using a combustion agent 221, thereby using high temperature combustion to remove the The film on the waste glass is finally treated, and finally the waste glass which has been removed from the film is processed (ie, the treatment step 23) to enhance the timeliness and efficacy of recycling the waste glass, thereby creating the essence of industrial utilization. Economic Value.

However, in the above-mentioned combustion mode of the film removing step 22, the amount of the burning agent 221 is required to be proportional, and the cost is high, and the waste glass is also required to be concentrated to a certain amount before being carried out. Treatment, not to mention the residue generated during the high-temperature combustion process will adhere to the waste glass, and will mainly produce carbon monoxide and acetaldehyde after combustion, and may also produce harmful chemicals such as methane, ethylene and benzene. It will affect the environment for a long time, and the smoke generated by its burning may also cause air pollution problems. Moreover, after the combustion is completed, it is necessary to carry out the cleaning operation to recycle the waste glass. Therefore, not only the resources cannot be made. It can be effectively recycled and reused, which will waste existing energy and increase the recovery processing time, and it will not meet the economic benefit value of recycling and reprocessing.

Therefore, an object of the present invention is to provide a method for recycling and processing a waste film glass, which has the effect of shortening the recycling process, thereby reducing environmental pollution and achieving the effects of recycling and recycling waste glass.

Therefore, the method for recycling waste film glass of the present invention comprises a feeding step, a crushing step, a sieving step and a treating step in sequence; wherein, by means of one of the crushing steps, the crushing device is adapted for cutting and having a film The glass is subjected to a fragmentation treatment, so that the fragmented glass after the fragmentation is further screened through the screening step, and the screening mesh, the vibrator and the jet device having the plurality of screening holes in the screening step are mutually coordinated. The waste glass and the film can be separated and collected so that the waste glass can be recycled (that is, the processing step), so that the overall recycling process can be consistently recovered, and can continue in an uninterrupted manner. Recycling treatment can effectively shorten the timeliness of the recycling process, and can effectively reduce the operating cost, and effectively achieve the effects of industrial resource reuse and economic value enhancement.
