Description

Technical Field

[0001] The utility model belongs to the technical field of glass processing, and in particular relates to a device for drying and crushing broken glass. Background Art

[0002] In the process of kiln glass firing, a certain amount of cullet is introduced into the batch. Because it can reduce the surface tension of the melt, increase the thermal radiation transmittance of the material layer, and it is easy to distribute into the batch, cullet has the effect of accelerating the melting of the batch and saving energy. There is no strict regulation on the particle size of cullet, but it should be uniform. According to practice, if the particle size of cullet is equivalent to that of other batch materials, soda ash will react with cullet first, making it difficult to dissolve quartz sand, and the whole melting process will slow down and deteriorate. The particle size of cullet should be much larger than that of other raw materials, which helps to prevent the stratification of batch materials and accelerate melting. When the particle size of cullet is less than 0.25mm and the particle size is between 2-20mm, both have good effects on melting. In production, the latter particle size is used to reduce the power used to crush the raw materials. Taking into account the processing factors of various shapes of cullet, a particle size of 20-40mm is usually used. When using purchased broken glass, due to the large fluctuation in quality and the large amount of impurities, in addition to cleaning, sorting, impurity removal and magnetic separation to ensure the quality of the glass, it is also necessary to frequently take samples for analysis and make appropriate adjustments to the batch materials according to their chemical composition. The processing process is cumbersome and it is difficult to ensure the quality of the finished product. In comparison, the glass liquid overflowing from the bottom of the kiln in the factory has the advantages of low impurity content, low recycling cost, high actual recovery rate, no need for iron removal, and the same chemical composition as the target product. The current process collects the overflowing glass liquid from the bottom of the kiln, recycles and crushes it for secondary use. Because the overflowing glass liquid is a high-temperature and viscous liquid, a water spray cooling device needs to be installed at the overflow port to cool the overflowing glass liquid. After cooling, the glass liquid becomes solid glass. The cooled solid glass can be simply crushed and then dried and crushed before it can be used as raw material.

[0003] Among them, patent document CN203771917 U discloses a glass crushing and drying machine, including: an air guide fan, a cylinder and a motor, the air guide fan is connected to the heater through an air inlet pipe, an electric heating tube is installed inside the heater, the heating tube is connected to the bottom of the cylinder through a pipeline, a discharge port is provided at the bottom of the cylinder, the motor output shaft extends into the cylinder from the top of the cylinder, a crushing blade is installed on the output shaft, a feed port and an exhaust fan are provided at the upper end of the cylinder, the exhaust fan is connected to the middle air inlet of the cyclone separator through a pipeline, an ash hopper is provided at the bottom of the cyclone separator, and the air outlet at the top of the cyclone separator is connected to the air inlet through a pipeline. The utility model has the function of crushing the broken glass while the crushing blade crushes the glass. However, during the crushing process, the cylinder is in a closed state, and glass cannot be added or discharged, and the production efficiency is low. Moreover, when the crushing blade crushes the broken glass in the closed cylinder, it is difficult to control the particle size of the produced broken glass, and it is easy to be over-crushed or under-crushed.

[0029] The drying shell 1 can enclose a space for accommodating other structures, such as accommodating the chain conveyor 4 and the transported broken glass, so that the drying airflow provided by the air supply member 5 can surround the transported broken glass, reduce the outward diffusion of the airflow, and ensure the drying effect.

[0030] The drying shell 1 is connected to a feed pipe 2 and a discharge pipe 3 . Cullet glass can be added into the drying shell 1 through the feed pipe 2 , and the dried cullet glass can be discharged through the discharge pipe 3 .

[0031] The chain conveyor 4 includes a chain for carrying materials. The chain is a hollow structure, which can allow the drying airflow provided by the air supply member 5 to pass through, thereby ensuring the flow of the drying airflow to ensure the drying effect.

[0032] The double-roll crusher is connected to the discharge pipe 3 , that is, it can receive the broken glass discharged from the discharge pipe 3 .

[0033] During operation, broken glass is continuously fed to the chain conveyor 4 in the drying shell 1 through the feed pipe 2. The broken glass moves continuously through the chain conveyor 4. The air supply member 5 provides a drying airflow to the moving chain to achieve drying of the moving broken glass. After the broken glass moves to the end of the chain conveyor 4, it can be discharged through the discharge pipe 3 to enter the double-roll crusher 6 to achieve crushing processing.

[0034] In this solution, the broken glass can be continuously transported and dried at the same time, and then the dried broken glass can be continuously crushed, realizing continuous operation. At the same time, the advantage of the double-roll crusher's uniform output particle size is utilized to improve the efficiency of glass drying and crushing, and also ensure the stability of the particle size of the produced broken glass.

[0035] like Figure 1 and Figure 2As shown, in some embodiments of the present scheme, the chain conveyor 4 includes a driving wheel 7, a driven wheel 8 and a chain row 9, and the air supply member 5 includes an air supply pipe 10 and an air supply head 11 connected to the air supply pipe 10, and the air supply head 11 is located between the driving wheel 7 and the driven wheel 8 and is provided with an air outlet 12 facing upward vertically.

By adjusting the gap between the two crushing rollers on the roller crusher 6, the discharge particle size is controlled to 20-40 mm, which meets the conditions for use as a raw material. In some other embodiments, the roller crusher 6 can also produce broken glass of other particle sizes.

[0047] like Figure 1 As shown, in some embodiments of the present invention, a collecting bin 15 is further included which is connected to the outlet of the roller crusher 6. Glass crushed by the roller crusher 6 can enter the collecting bin 15 for use.
