Description

Technical Field

[0001] The present invention relates to the technical field of electronic glass powder making, and in particular to an electronic glass powder making system and method. Background Art

[0002] Electronic glass is a kind of glass product with high quality requirements, and has very high requirements on the melting defects in glass products. In order to improve the melting quality of glass and reduce glass defects, it is an important process method to mix a certain proportion of glass powder into the batch material during the melting process. The melting temperature of glass powder (commonly known as clinker) is lower than that of quartz sand batch material (commonly known as raw material), which not only reduces the difficulty of melting, but also can obtain good melting quality through the combination of raw and clinker. Therefore, making glass powder with a certain mesh size is a necessary process in the processing of electronic glass.

[0003] Generally, glass powder is produced by pre-crushing unqualified large pieces of finished glass into smaller pieces, then grinding them in a ball mill and processing them into powdered glass powder less than 2 mm, which is then screened to obtain glass powder of the required specifications. In this process, broken glass pieces need to be manually transported to the ball mill and from the ball mill to the screening machine. At the same time, glass powder that exceeds the regulations after screening needs to be put into the machine a second time, and the efficiency of the entire powder making work is low. In order to meet the production capacity requirements, one broken glass machine needs to be equipped with more than 3 ball mills. The equipment takes up a large space and has low work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an electronic glass powder making system and method to overcome the problems existing in the prior art. The present invention can first process broken glass pieces through a crusher to mostly generate qualified glass powder within specifications. The production efficiency of the crusher is more than three times that of a ball mill with the same power, saving ball mill equipment and factory space. At the same time, the ball mill performs secondary processing on unqualified glass powder that exceeds specifications and then returns it to the screening machine, thereby improving the powder making efficiency of the system and realizing the self-circulation of the powder making process.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides an electronic glass powder making system, comprising a conveyor, the conveyor is connected to a diverter, and the diverter is connected to a plurality of pulverizing systems; The pulverizing system includes a pulverizer for pulverizing broken glass pieces into glass powder. The pulverizer is connected to an elevator. The elevator includes a first entrance and a second entrance. The elevator is connected to a screening machine. The screening machine includes an upper layer and a lower layer for screening the glass powder. The screening machine is respectively connected to a first vibrating feeder and a ball mill. The first vibrating feeder is used to transport qualified glass powder to a silo. The ball mill is used to perform secondary grinding on unqualified glass powder. The first vibrating feeder is connected to a silo. The silo is connected to a hopper. The ball mill is connected to a second vibrating feeder. The second vibrating feeder is connected to the elevator.

[0006] In a second aspect, the present invention provides an electronic glass powder making method, based on the above-mentioned electronic glass powder making system, comprising the following steps: Step 1: The processed broken glass pieces are transported to a diverter by a conveyor, and then enter several crushers of a crushing system through the diverter for crushing to obtain glass powder; Step 2: transporting the glass powder to a screening machine through an elevator for screening to obtain qualified powder and unqualified powder; Step 3: transport the qualified powder to the silo through the first vibrating feeder, and then transport it to the melting process through the hopper; grind the unqualified powder for a second time through the ball mill to obtain secondary glass powder; Step 4, transporting the secondary glass powder to the elevator through the second vibrating feeder, and performing step 2 again; Furthermore, the step 1 is specifically as follows: the processed broken glass pieces are transported to a diverter by a conveyor, and enter the crusher inlet of several crushing systems through the diverter, and the broken glass pieces enter the crusher through the crusher inlet to be crushed to obtain glass powder, and the glass powder flows out from the crusher outlet and enters the first inlet of the elevator; Furthermore, the conveyor adopts a belt transmission method; Furthermore, the pulverization is carried out by means of a rotary hammer stirring method; Furthermore, the screening in step 2 is specifically as follows: When the particle size of the glass powder is less than or equal to 1.5 mm, it is qualified powder and enters the upper layer of the screening machine; When the particle size of glass powder is greater than 1.5 mm, it is considered unqualified powder and enters the lower layer of the screening machine; Furthermore, the step 4 specifically includes: transporting the secondary glass powder to the second entrance of the elevator through the second vibrating feeder, and performing step 2 again; Further, the elevator includes a chain conveyor, and a plurality of small hoppers are suspended on the chain conveyor; Furthermore, the elevator lifts the glass powder from a low place to a high place through a plurality of small hoppers in cooperation with a chain conveyor, and the small hoppers are turned over to transport the glass powder to the screening machine.

[0007] In a third aspect, the present invention provides a glass powder obtained based on the above-mentioned electronic glass powder making method.

[0008] The above technical solution has the following advantages or beneficial effects: In the first aspect, the present invention provides an electronic glass powder making system. By introducing a combination of a diverter and multiple crushing systems, the system can process raw materials in parallel, significantly improving production efficiency; by arranging the elevator with a first inlet and a second inlet, it can be used for the input of raw materials of different particle sizes or properties, thereby increasing the flexibility of processing; by dividing the screening machine into an upper layer and a lower layer, it can achieve accurate grading of the crushed material, thereby ensuring the uniformity of the particle size of the final product; the screened unqualified particles are fed back into the elevator through a second vibrating feeder, thereby forming a closed-loop feedback mechanism, effectively utilizing substandard materials, reducing raw material waste, and improving resource utilization.

[0009] In the second aspect, the present invention provides a method for making electronic glass powder. Through the coordinated operation of conveyors, diverters, crushers, elevators, screens, vibrating feeders, ball mills and other equipment, an efficient and precise production line is formed. Broken glass pieces are crushed, screened, and re-grinded to finally obtain glass powder that meets the requirements. The entire process has a high degree of automation, reduces manual intervention, saves ball mill equipment and factory space, and improves production efficiency. The glass powder is accurately screened by a screening machine to ensure the uniformity of the particle size of qualified powder and meet the high requirements of electronic glass for raw materials. Unqualified powder can be reused after secondary grinding, avoiding waste of raw materials. This not only improves resource utilization, but also reduces waste generation, which is in line with the concept of green production.

[0010] Furthermore, the belt conveyor method can realize the rapid and continuous transmission of glass raw materials or products on the production line, which can significantly improve production efficiency and make the entire powder making process smoother and more efficient.

[0011] Furthermore, the rotary hammer stirring achieves efficient crushing by using the high-speed rotating hammer head to strongly impact and shear the material. Compared with traditional crushing equipment, this method not only has higher crushing efficiency and shorter production cycle, but also can ensure that the particle size of the crushed electronic glass powder is uniform and the particle size is controllable.

[0012] Furthermore, by setting a particle size threshold of 1.5 mm, the glass powder is clearly distinguished into qualified powder and unqualified powder, ensuring the uniformity of the particle size of the final product. Glass powder with uniform particle size can show better stability and consistency in subsequent processing and application, thereby improving the overall product quality.

[0013] Furthermore, as the core component of the elevator, the chain conveyor has stable transmission capacity and high transmission speed. Through the continuous movement of the chain, the small hopper can continuously lift the glass powder from a low place to a high place, ensuring the continuity and efficiency of the production process.

[0014] In a third aspect, the present invention provides a glass powder. Through the above-mentioned powder making method, the prepared glass powder has uniform particle size and controllable particle size, which can meet the strict requirements of material fineness in different fields and help improve the processing performance of the product and the quality of the final product.
