[0046] The following is based on Figures 1 to 5 The utility model provides a photovoltaic glass production with material supply system and photovoltaic glass production line are introduced.

Among them, upper cover body 2 is covered in the upper portion of hopper 1, and the lower portion of hopper 1 is provided with hopper discharge port. Upper cover body 2 is provided with first feeding port 21 and second feeding port 22, and first feeding port 21 is the feeding port of powder material for photovoltaic glass production, and second feeding port 22 is the feeding port of glass broken material. The upper portion of crushing device 3 is provided with mixing feeding port 31, and the lower end of crushing device 3 is provided with broken material discharge port. And make crushing device 3 be configured to be used for crushing powder material for photovoltaic glass production and glass broken material.

[0048] It should be noted that the hopper 1 in the present application is not specifically limited, and the volume, size and shape of the hopper 1 can be selectively set according to actual needs. In specific implementation, the hopper 1 is preferably in the form of a funnel.

[0049] It should also be noted that the structure of the upper cover body 2 in the present application is not specifically limited, and can be selectively adapted according to the setting form of the hopper 1. The present application sets the upper cover body 2, and covers the upper cover body 2 on the upper portion of the hopper 1, so that the hopper 1 is in a relatively sealed state, which can block foreign matter in the environment, reduce the influence of foreign matter on the quality of glass products, and also prevent glass powder from polluting the environment.

[0050] In specific implementation, for example, Figure 1As shown, the upper cover body 2 is provided with a first feeding port 21 and a second feeding port 22. In specific work, the photovoltaic glass production powder can be added to the hopper 1 through the first feeding port 21, and the glass scrap can be added to the hopper 1 through the second feeding port 22. As a preferred embodiment, the first feeding port 21 is connected with a raw material feeding machine, and the second feeding port 22 is connected with a glass scrap feeding machine. According to the production needs, the feeding machine provides the hopper 1 with the photovoltaic glass production powder and the glass scrap in a proper proportion.

[0051] It should also be pointed out that the crushing device 3 in the present application is not specifically limited, which can be any device capable of further crushing the photovoltaic glass production material. In specific implementation, the crushing device 3 can be a blade type crushing device or a rotating shaft type crushing device. As a preferred embodiment, the crushing device 3 is a pulverizer. Specifically, it can be a hammer type pulverizer as shown in Figure 2 By providing the photovoltaic glass production material feeding system with the crushing device 3, the photovoltaic glass production material, especially the glass scrap, can be crushed. In turn, the particle size of the photovoltaic glass production material is more fine, which can effectively increase the heating area of the photovoltaic glass production material during melting, thereby achieving the effect of shortening the melting time of the photovoltaic glass production powder and reducing energy consumption. At the same time, it can also improve the uniform mixing degree of the glass scrap and the photovoltaic glass production powder, and improve the quality of the glass product.

[0052] In addition, by providing the first belt conveyor 4, the mixed photovoltaic glass production powder and glass scrap can be more stably provided to the crushing device 3. When the first belt conveyor 4 feeds the photovoltaic glass production material to the crushing device 3, it also helps the uniform mixing of the glass scrap and the photovoltaic glass production powder.

[0053] In some embodiments, as shown in Figure 2 and Figure 3 The crushing device includes a box body, a first crushing assembly 32, a second crushing assembly 33, a first blocking piece 34 and a second blocking piece 35. The box body includes a first side wall 311, a third side wall 313, a second side wall 312 and a fourth side wall 314 connected in sequence, and the box body as a whole is square. The upper part of the box body is a mixing feeding port 31, and the lower part of the box body is a crushed material discharging port. In specific implementation, the first crushing assembly 32 and the second crushing assembly 33 are respectively driven to rotate by driving motors, and the glass scrap is crushed under the extrusion of the first crushing assembly 32 and the second crushing assembly 33.

[0054] Specifically, as shown in Figure 2 and Figure 3As shown, the first crushing component 32 includes a first rotating shaft 321 and a first circular crushing disc 322. The first rotating shaft 321 is connected to the first side wall 311 and the second side wall 312 via a bearing seat. A plurality of first circular crushing discs 322 are fixed at intervals on the first rotating shaft 321. Each first circular crushing disc 322 is provided with a plurality of first crushing teeth in the circumferential direction. The first crushing teeth extend obliquely in the circumferential direction.

[0055] Specifically, such as Figure 2 and Figure 3 As shown, the second crushing component 33 is arranged side by side with the first crushing component 32. The second crushing component 33 includes a second rotating shaft 331 and a second circular crushing disc 332. The second rotating shaft 331 is connected to the first side wall 311 and the second side wall 312 through a bearing seat. A plurality of second circular crushing discs 332 are fixed at intervals on the second rotating shaft 331. Each second circular crushing disc 332 is provided with a plurality of second crushing teeth in the circumferential direction. The second crushing teeth extend obliquely in the circumferential direction.

[0056] In practical implementation, the number of the first circular crushing disc 322 and the second circular crushing disc 332 is not specifically limited and can be selectively set according to actual needs. To achieve better crushing effect, the diameters of the first and second circular crushing discs 322 and 332 should be increased as much as possible, as should the number of first crushing teeth on each first circular crushing disc 322 and the number of second crushing teeth on each second circular crushing disc 332. Within the range of mechanical bearing capacity, the thickness of the first and second circular crushing discs 322 and 332 should be minimized as much as possible.

[0057] For example Figure 2 and Figure 3 As shown, a plurality of first barrier plates 34 are vertically spaced and fixed to the third sidewall 313 and extend toward the first crushing assembly 32. The journal between two adjacent first circular crushing discs 322 corresponds to and engages with one first barrier plate 34. A plurality of second barrier plates 35 are vertically spaced and fixed to the fourth sidewall 314 and extend toward the second crushing assembly 33.

The first guide slope 341 extends obliquely downward from the third side wall 313 toward the first crushing component 32. The extended end of the first barrier plate 34 is provided with a first arc-shaped groove 342 that is concave toward the third side wall 313.

[0060] The present application sets the first guide inclined surface 341 on the first blocking sheet 34 and sets the second guide inclined surface 351 on the second blocking sheet 35, so that the crushed material can be guided to avoid blockage.

[0061] In some embodiments, the photovoltaic glass production material feeding system further comprises a stirring device (not shown in the figure), which is arranged in the hopper 1 and above the hopper discharge port. In specific implementation, the stirring device comprises a stirring shaft and a driving motor, the stirring shaft is installed at a position adjacent to the hopper discharge port, one end of the stirring shaft extends out of the side wall of the hopper and is in driving connection with the driving motor, and a plurality of stirring rods which are perpendicular to the stirring shaft are uniformly distributed on the outer side of the stirring shaft. In specific work, the stirring device stirs the mixed glass fragments and the photovoltaic glass production powder in the hopper 1. The present application can better mix the glass fragments and the photovoltaic glass production powder by setting the stirring device, and at the same time, can also avoid the hopper 1 from being blocked.

[0062] The stirring device in the present application is not specifically limited, which can be any device capable of stirring and mixing the glass fragments and the photovoltaic glass production powder. For example, the stirring device can be a paddle stirrer, a screw stirrer, etc.

[0063] In some embodiments, the first feeding port 21 and the second feeding port 22 are both located directly above the stirring device. Then, the mixing of the glass fragments and the photovoltaic glass production powder can be more easily realized in the stirring process of the stirring device.

[0064] In some embodiments, the photovoltaic glass production material feeding system further comprises a first protection channel 5, the first protection channel 5 extends from the hopper discharge port to the mixing feeding port 31, and the first belt conveyor 4 is located in the first protection channel 5. The present application can make the first belt conveyor 4 work in a relatively closed environment by setting the first protection channel 5 and making the first belt conveyor 4 located in the first protection channel 5, so as to isolate the external environment, thereby isolating foreign matter in the external environment from contaminating the raw materials, and also preventing the raw material powder from spreading to the external environment.

[0065] In some embodiments, as Figure 1As shown, the first protective channel 5 comprises a horizontal protective channel 51 and a vertical protective channel 52.

In actual use, when the glass production material supply system is in normal operation, the door body 11 is in a closed state. When the glass production material supply system is not in operation, the door body 11 can be opened to clean the raw materials in the hopper 1 in time to prevent the raw materials from piling up.

By arranging the second belt conveyor 7, the photovoltaic glass production material discharged from the crushing device 3 can be transported to the glass melting furnace 6, and the glass melting furnace can be stably provided with glass production materials. In addition, by extending the second belt conveyor 7 above the feeding pool 61, the glass particles and the photovoltaic glass raw materials can be mixed again when the materials are dropped, so as to achieve a better mixing effect and improve the quality of the photovoltaic glass.

[0070] In some embodiments, the photovoltaic glass production line further comprises a second protective channel 8, which is connected with the crushed material discharge port and extends from the crushed material discharge port to above the feeding pool 61. The second belt conveyor 7 is located in the second protective channel 8.
