[0002] In the field of glass production (such as ultra-white electronic glass), in order to pass the environmentally friendly product certification, the raw materials for producing glass products need to be environmentally friendly recycled materials, which requires recycling the unqualified products produced by its own production line as environmentally friendly recycled materials. However, most of the unqualified products produced by the back end have undergone packaging processes such as lamination or spacer paper protection. It is difficult and inefficient to manually clean impurities before recycling materials are fed. Therefore, providing a processing equipment for glass environmentally friendly recycled materials can greatly improve efficiency.

[0003] Patent CN211755372U discloses a waste glass bottle crushing and separation device. When in use, the recycled glass bottles are directly thrown into the hopper. After being crushed by the roller group, the glass slag and waste paper scraps are mixed together. When falling from the conveying pipe, the strong wind blown out by the fan blows out from the opening on one side. Most of the glass slag continues to fall and then is discharged from the discharge port, while the lighter waste paper scraps and some light glass slag are blown into the cyclone. The spiral rising airflow generated in the cyclone will further separate the waste paper scraps and light glass slag entering therein. The waste paper scraps are discharged from the exhaust pipe, and the light glass slag falls and is finally discharged from the discharge port. Although this patent can separate the glass and the paper label thereon through the device disclosed by it, it does not involve how to separate the glass and the coating thereon through mechanical equipment.

[0029] refer to Figures 1 to 3 The utility model proposes a glass recycling device 100, comprising: a crushing mechanism 10, used for crushing glass raw materials with paper materials and coatings; an air selection mechanism 20, the air selection mechanism 20 comprising an air selection chamber 22, a fan 24 arranged in the air selection chamber 22 and a paper material collecting part 26, the air selection chamber 22 having a top feed port 21 and a bottom discharge port 23 for receiving crushed materials from the crushing mechanism 10, when projected onto a horizontal plane, the fan 24 and the paper material collecting part 26 are located at the top feed port 21 On opposite sides; a demolding mechanism 30, the demolding mechanism 30 includes a cleaning tank 32 arranged below the bottom discharge port 23, a stirring portion 34 for stirring in the cleaning tank 32, and an annular groove 36 arranged on the circumferential outer side of the cleaning tank 32, the cleaning tank 32 has a demolding agent feed pipe and a clean water feed pipe, the annular groove 36 is configured to receive overflow water and detached coating when the cleaning tank 32 is in an overflow state, and the annular groove 36 has a drain pipe; a dehydration mechanism 40, which is connected to the demolding mechanism 30 and is used to dehydrate the broken glass.

[0030] In an embodiment of the utility model, the glass raw material can be unqualified glass with the required composition, which is covered with paper and film. The paper is, for example, packaging materials such as spacer paper, and can also be other possible paper such as paper labels. First, the glass raw material is crushed by a crushing mechanism 10, at which time the glass and the paper and film on it are all crushed. After that, the crushed material leaves the discharge port of the crushing mechanism 10 and enters the air separation mechanism 20 through the top feed port 21. The crushed material enters in a scattered state and falls naturally. In the process of the crushed material falling naturally, the fan 24 blows air to it from one side, so that the lighter paper is blown into the paper collection part 26 on the opposite side, while the broken glass is not affected by the wind and directly falls into the bottom discharge port 23, thereby achieving the separation of paper and broken glass. Afterwards, the broken glass enters the demolding mechanism 30, and the prepared demolding agent is added to the cleaning tank 32 through the demolding agent feeding pipe, and the stirring part 34 is used to make the broken glass after the paper material is separated fully contact and mix with the demolding agent in the cleaning tank 32, and a chemical reaction occurs to dissolve the adhesive material. After the demolding is completed, clean water is added through the clean water feeding pipe to make the cleaning tank 32 overflow. Since the coating is light in weight, the film is in a floating state after demolding. When the cleaning tank 32 is in an overflow state, the separated coating can follow the overflow water into the annular groove 36 to separate the coating from the broken glass. The liquid in the annular groove 36 is discharged through the drain pipe, and impurities such as the coating accumulate in the annular groove 36, which can be shoveled out and collected by tools. Afterwards, the broken glass is dehydrated in the dehydration mechanism 40 to obtain the processed glass recycling material. The utility model provides a device that can separate glass and the paper material and the coating thereon, thereby saving manpower and improving production efficiency.

[0031] refer to Figure 2 In some embodiments, the crushing mechanism 10 includes a crushing chamber 12 and at least one pair of crushing rollers 14 arranged in the crushing chamber 12 and rotating in opposite directions. The crushing rollers 14 are used to crush the glass raw materials, and the crushing chamber 12 allows the crushing process to be carried out in a relatively closed space to avoid dust pollution. The crushing mechanism 10 and the air separation chamber 22 can be connected through an inclined channel 16, and the inclined channel 16 can play a role in guiding the crushed materials into the air separation chamber 22. Moreover, compared with the completely vertical setting, the inclined channel 16 can appropriately reduce the flow speed of the crushed materials, thereby prolonging the time for them to be affected by the wind of the fan 24, and more effectively realizing wind separation.

[0032] The fan 24 can be arranged on the side wall of the first side of the air selection chamber 22 and blow air to the second side opposite to the first side, and the paper material collection part 26 is arranged in the area where the second side is located. The fan 24 can be arranged on the side below the top feed port 21 to facilitate blowing air to the naturally falling broken materials, and the fan 24 can be arranged in the middle of the air selection chamber 22 in the vertical direction. The paper material collection part 26 can be located on the side below the fan 24, which is conducive to allowing the paper materials blown to the second side to scatter into the paper material collection part 26 and be effectively collected. The fan 24 is equipped with a corresponding drive motor, and the wind force is adjusted by the motor. The operator can adjust the wind force of the fan 24 by observing the composition of the materials falling into the paper material collection part 26 to achieve the optimal material screening state. The paper material collection part 26 can be in the form of a bag or a box.

[0033] refer to Figure 2 In some embodiments, the air selection mechanism 20 includes a blocking portion 28 disposed between the fan 24 and the paper material collecting portion 26, the blocking portion 28 having an inclined surface 29 inclined from top to bottom toward the fan 24, and the lower portion of the inclined surface 29 is connected to the bottom discharge port 23. The inclined surface 29 faces the fan 24 and the distance between the upper portion of the inclined surface 29 and the fan 24 is greater than the distance between the lower portion of the inclined surface 29 and the fan 24. Finer broken glass and broken glass dust, because of their greater mass than impurities such as paper materials, can be blocked by the inclined surface 29 and gradually slide down to the bottom discharge port 23.

[0034] The stirring part 34 can have a continuous stirring mode and an intermittent stirring mode. When the film stripping process begins, the stirring part 34 is first adjusted to the continuous stirring mode. After a certain period of time, when it is necessary to judge whether the film stripping is completed, the stirring part 34 is adjusted to the intermittent stirring mode so as to manually observe the film peeling off of the surface of the broken glass. When it is determined that the film peeling state is good, the stirring part 34 is adjusted to the continuous stirring mode, and the clean water feed pipe is opened at the same time, and clean water is continuously added to make the cleaning tank 32 overflow. The liquid flowing into the annular groove 36 can enter the factory sewage treatment station through the drain pipe for sewage treatment. When there is no impurity such as film on the liquid surface of the cleaning tank 32, the clean water feed pipe can be closed, and the discharge port of the cleaning tank 32 can be opened, so that the broken glass enters the dehydration mechanism 40 through the discharge port with the running water.

[0035] refer to Figure 3 In some embodiments, the stirring part 34 includes a plurality of horizontal rods 33 and a plurality of stirring rods 35 extending in a vertical direction, wherein the plurality of horizontal rods 33 extend in a plurality of horizontal directions and intersect at the same point in the middle, and the plurality of stirring rods 35 are arranged at both ends of the plurality of horizontal rods 33. Such an arrangement is conducive to more sufficient and effective stirring and improves the stirring effect.

[0036] refer to Figure 1 and Figure 3In some embodiments, the demolding mechanism 30 includes a bracket 31, and the stirring part 34 is rotatably connected to the bracket 31. The bracket 31 can be installed to the air selection chamber 22 and has an L-shape. Of course, it can also be installed on other suitable components and designed to be other suitable shapes. The bracket 31 can be telescopic or movable in the vertical and / or horizontal direction. On the one hand, it is convenient to adjust the appropriate position of the stirring part 34 in the cleaning tank 32 according to actual conditions, thereby improving flexibility and adaptability; on the other hand, the stirring part 34 can be moved to a position to avoid the material during the process of the material falling into the cleaning tank 32. The bracket 31 can adopt any known telescopic component to achieve telescopic extension in the vertical and / or horizontal direction, and the bracket 31 can be moved in the vertical and / or horizontal direction by, for example, cooperating with a guide rail slider.

[0037] refer to Figure 3 In some embodiments, the dehydration mechanism 40 is a centrifugal dehydrator, which has an outer cylinder 42 and a rotatable inner cylinder 44, and a plurality of through holes are distributed on the inner cylinder 44. When the inner cylinder 44 rotates, the water contained in the material therein is thrown out through the plurality of through holes under the action of centrifugal force to achieve dehydration. After the broken glass enters the centrifugal dehydrator, it can be left to stand first, so that the running water flows out through the plurality of through holes of the inner cylinder 44, and drains naturally for a period of time, and then the centrifugal dehydrator is turned on to throw out the water to the required moisture content of the raw material. The sewage generated by the dehydration mechanism 40 can enter the factory sewage station through the external sewage pipe network for sewage treatment.

[0038] refer to Figure 1 and Figure 3 In some embodiments, the device 100 further includes a mounting cylinder 50, and the film stripping mechanism 30 and the dehydration mechanism 40 are at least partially disposed in the mounting cylinder 50. On the one hand, the mounting cylinder 50 can provide mounting and protection functions, and on the other hand, can realize an integrated structure, facilitate installation and transportation, and can also make the structure more compact and provide a more beautiful appearance.

[0039] refer to Figure 1 and Figure 3 In some embodiments, the device 100 further includes a belt conveyor mechanism 52 disposed below the discharge port of the dehydration mechanism 40. After the dehydration is completed, the discharge port of the dehydration mechanism 40 is opened, and the broken glass gradually falls onto the conveyor belt of the belt conveyor mechanism 52, and is conveyed to a container or a packaging device, and is combined with a packaging machine for bulk bag packaging, or is conveyed to a broken glass warehouse for stacking. During the conveying process, the operator can stand on both sides of the conveyor belt to select the agglomerated broken glass blocks and break them manually.

[0040] In some embodiments, if the production line requires a lower moisture content of the cullet, the device 100 may further include a hot air drying mechanism for blowing hot air to the belt conveyor mechanism 52 to further reduce the moisture content of the cullet.

[0041] The wastewater generated in this application can be collected and treated in conjunction with the glass production line's own wastewater treatment station, because the wastewater generated by the cutting and cleaning processes of the glass production line needs to be treated, and the process is easy to implement.

[0042] The utility model mechanically processes environmentally friendly recycled materials of glass (such as ultra-white electronic glass) so that the recycled materials meet the technical requirements of raw material feeding, can replace manual sorting and processing, improve production efficiency, simplify the process, and meet the needs of industrialized production.
