Description

Technical Field

[0001] This utility model relates to the field of glass crushing technology, and in particular to an ultrasonic-assisted ultrafine glass powder crushing device. Background Technology

[0002] In the field of glass powder production, the preparation of ultrafine glass powder is crucial for improving the performance of glass powder in many applications, such as electronic packaging materials, ceramic glazes, and abrasives, where ultrafine glass powder can significantly improve product performance. In practical applications, a highly efficient ultrasonic-assisted ultrafine glass powder pulverizing equipment typically requires the following technologies:

[0003] 1. Grinding Technology: Utilizing a combination of grinding methods, such as ball mill grinding and air jet milling. Ball mills use grinding media (such as steel balls, ceramic balls, etc.) moving within a rotating cylinder to impact and grind glass raw materials, gradually refining the particles.

[0004] 2. Ultrasonic Assisted Technology: An ultrasonic generator is introduced to produce high-frequency ultrasonic waves. When the ultrasonic waves propagate in the crushing medium, they generate local high temperature, high pressure, and powerful shock waves and micro-jets, which produce strong impact and erosion on the surface of glass particles, accelerating the crushing of glass particles.

[0005] Traditional glass crushing mainly relies on mechanical grinding (such as grinding discs). This method has significant limitations. On the one hand, the final fineness of the crushing is limited by the design and wear of the grinding structure itself, making it difficult to break through the bottleneck and obtain the required ultrafine powder. On the other hand, the material usually undergoes only a single crushing process in the crushing chamber, resulting in many particles being discharged before reaching the target fineness. A single crushing process is difficult to ensure sufficient and uniformity. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an ultrasonic-assisted glass powder ultrafine pulverizing device, which solves the problem that traditional glass pulverizing mainly relies on mechanical grinding (such as grinding discs). This method has significant limitations. On the one hand, the final fineness of the pulverized powder is limited by the design and wear of the grinding structure itself, making it difficult to break through the bottleneck and obtain the required ultrafine powder. On the other hand, the material usually undergoes only a single crushing process in the pulverizing chamber, resulting in many particles being discharged before reaching the target fineness. The technical problem that a single crushing process cannot ensure sufficient and uniformity is difficult to solve.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An ultrasonic-assisted ultrafine glass powder pulverizing device includes a pulverizing barrel, a fixed grinding cone fixedly installed inside the pulverizing barrel, a movable grinding cone rotatably installed inside the pulverizing barrel, a lifting cylinder fixedly installed inside the pulverizing barrel, a spiral feeding rod rotatably installed inside the lifting cylinder, an ultrasonic generator uniformly fixedly installed at the bottom end of the pulverizing barrel, a disc-shaped plate fixedly installed on the lifting cylinder, and the spiral feeding rod and the movable grinding cone fixedly connected.

[0009] Preferably, a drive unit is fixedly installed on the crushing barrel, and the output shaft of the drive unit is fixedly connected to the moving grinding cone.

[0010] Preferably, a feeding hopper is fixedly installed at the top of the fixed grinding cone.

[0011] Preferably, a support base is rotatably mounted on the crushing barrel.

[0012] Preferably, a pin plate is slidably mounted on the support base.

[0013] Preferably, a spring is installed between the pin plate and the support base.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The gradually narrowing space between the moving and stationary grinding cones ensures that the glass is fully broken into smaller powders before being discharged to the bottom of the crushing tank. Furthermore, the dynamic circulation path formed by the lifting cylinder and the spiral feed rod allows the glass powder to circulate multiple times through the action zone of the ultrasonic generator. This cyclic re-crushing design, combining mechanical grinding (moving and stationary grinding cones) with ultrasonic cavitation crushing (ultrasonic generator), significantly improves crushing efficiency and effect, effectively breaking through the fineness bottleneck of traditional grinding and ensuring the acquisition of uniform and qualified ultrafine glass powder.

[0022] This application provides an ultrasonic-assisted ultrafine glass powder pulverizing device, which effectively solves the problem that traditional glass pulverizing mainly relies on mechanical grinding (such as grinding discs). This method has significant limitations. On the one hand, the final fineness of the pulverized powder is limited by the design and wear of the grinding structure itself, making it difficult to overcome the bottleneck and obtain the required ultrafine powder. On the other hand, the material usually undergoes only a single crushing process in the pulverizing chamber, resulting in many particles being discharged before reaching the target fineness. The technical problem of insufficient and uniform crushing in a single crushing process is difficult to ensure. The gradually narrowing space between the moving grinding cone and the fixed grinding cone ensures that the glass is fully broken into smaller powders before being discharged to the bottom of the pulverizing barrel. Furthermore, the dynamic circulation path formed by the lifting cylinder and the spiral feeding rod allows the glass powder to circulate through the action area of ​​the ultrasonic generator multiple times. This cyclic re-pulverizing design, combined with the dual pulverizing mechanism of mechanical grinding (moving grinding cone and fixed grinding cone) and ultrasonic cavitation crushing (ultrasonic generator), significantly improves the pulverizing efficiency and effect, effectively overcomes the fineness bottleneck of traditional grinding, and ensures the acquisition of uniform and qualified ultrafine glass powder.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that traditional glass crushing mainly relies on mechanical grinding (such as grinding discs). This method has significant limitations. On the one hand, the final fineness of the crushing is limited by the design and wear of the grinding structure itself, making it difficult to overcome the bottleneck and fully obtain the required ultrafine powder. On the other hand, the material usually undergoes only a single crushing process in the crushing chamber, resulting in many particles being discharged before reaching the target fineness. The technical problem that a single crushing process cannot ensure sufficient and uniformity is difficult to solve. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides an ultrasonic-assisted glass powder ultrafine pulverizing device, including a pulverizing barrel 1, a fixed grinding cone 2 fixedly installed inside the pulverizing barrel 1, a movable grinding cone 3 rotatably installed inside the pulverizing barrel 1, and a lifting cylinder 4 fixedly installed inside the pulverizing barrel 1.

[0026] The lifting cylinder 4 is equipped with a rotating spiral feeding rod 5. The bottom of the crushing barrel 1 is uniformly and fixedly equipped with an ultrasonic generator 6. The lifting cylinder 4 is fixedly equipped with a disc 7. The spiral feeding rod 5 and the moving grinding cone 3 are fixedly connected. The crushing barrel 1 is fixedly equipped with a drive unit 8.

[0027] The output shaft of the drive unit 8 is fixedly connected to the moving grinding cone 3. The top of the fixed grinding cone 2 is fixedly installed with a feeding hopper 9. A support seat 11 is rotatably installed on the crushing barrel 1. A pin plate 12 is slidably installed on the support seat 11. A spring 13 is installed between the pin plate 12 and the support seat 11.

[0028] Crushing barrel 1: As the main structure of the entire equipment, it provides installation space for various internal components and is also the place for glass crushing. It is equipped with components such as fixed grinding cone 2, moving grinding cone 3, and lifting cylinder 4. An ultrasonic generator 6 is installed at the bottom. After crushing, the glass powder can be discharged by rotating and tilting. It is fixed in position by support base 11, pin plate 12 and spring 13 to ensure stable operation.

[0029] Fixed grinding cone 2: In conjunction with the moving grinding cone 3, it provides a working space for grinding and crushing glass. The space between the fixed grinding cone 2 and the moving grinding cone 3 gradually decreases, which helps to grind the glass into smaller powders. The feed hopper 9 installed at the top guides the glass to be crushed into the space between the fixed grinding cone 2 and the moving grinding cone 3.

[0030] The moving grinding cone 3 rotates under the drive of the drive group 8, grinding and crushing the glass that enters between the fixed grinding cone 2 and the moving grinding cone 3. The gradually narrowing gap formed with the fixed grinding cone 2 enables the glass to be gradually crushed. At the same time, the moving grinding cone 3 is fixedly connected to the spiral feed rod 5, driving the spiral feed rod 5 to rotate synchronously.

[0031] Elevating cylinder 4: Provides rotation space for spiral feeder 5. Its function is to lift the glass powder that falls at the bottom of crushing barrel 1 and enters it to the top and then discharge it, so that the glass powder can fall onto the disc 7, thereby realizing the circulation of glass powder in the equipment. It passes through the ultrasonic generator 6 multiple times to achieve the purpose of thorough crushing.

[0032] Spiral feed rod 5: It rotates under the drive of the moving grinding cone 3. When it rotates, it lifts the glass powder that has entered the lifting cylinder 4 upward. It is a key component to realize the circulation of glass powder in the equipment and ensures that the glass powder can be continuously crushed by the ultrasonic generator 6.

[0033] Ultrasonic generator 6: generates ultrasonic waves. When the glass powder passes through the bottom of the crushing barrel 1, the cavitation effect of the ultrasonic waves is used to further break the glass powder into finer ultrafine powder, thereby improving the fineness of the glass powder and enhancing the crushing effect.

[0034] Disc 7: Receives glass powder discharged from the top of the lifting cylinder 4. The inclined design of the top of the disc 7 allows the glass powder to fall back onto the edge of the bottom of the crushing barrel 1, and then pass through the ultrasonic generator 6 again, forming a dynamic circulation path for the glass powder, which helps to fully crush the glass powder.

[0035] Drive group 8: provides power for the rotation of the moving grinding cone 3, and is fixedly connected to the moving grinding cone 3 through the output shaft. After starting, it drives the moving grinding cone 3 to rotate, thereby realizing the grinding and crushing operation of glass;

[0036] Feed hopper 9: As the inlet for glass raw materials, it guides the glass to be crushed smoothly into the grinding area between the stationary grinding cone 2 and the moving grinding cone 3, ensuring the orderly progress of the crushing work;

[0037] Support base 11: Provides installation space for crushing barrel 1 and pin plate 12. When crushing barrel 1 needs to be tilted to discharge glass powder, it plays a supporting and rotating role. When the equipment is running normally, it works with pin plate 12 and spring 13 to ensure the stability of crushing barrel 1.

[0038] Pin plate 12: When pressed, it can overcome the elastic force of spring 13 and slide downward, which facilitates the rotation of the crushing barrel 1 to discharge glass powder. When released, it slides upward under the elastic force of spring 13, and the pin on it is inserted into the pin hole at the bottom of the crushing barrel 1 to fix the position of the crushing barrel 1.

[0039] Spring 13: Provides an upward elastic force to pin plate 12. When pin plate 12 is released, it pushes pin plate 12 to slide upward, so that the pin on pin plate 12 is inserted into the pin hole at the bottom of crushing barrel 1, fixing the position of crushing barrel 1 and ensuring stable operation of the equipment. When pin plate 12 is pressed, spring 13 is compressed, providing conditions for the rotation operation of crushing barrel 1.

[0040] Working principle:

[0041] The first step is to place the glass to be crushed in the feed hopper 9. The glass will enter the space between the fixed grinding cone 2 and the moving grinding cone 3 along the feed hopper 9. Then, the drive unit 8 is started, which will drive the moving grinding cone 3 to rotate. When the moving grinding cone 3 rotates, it will grind and crush the glass. As the space between the fixed grinding cone 2 and the moving grinding cone 3 gradually becomes smaller, the glass will be gradually ground into smaller powder. Then, these glass powders will fall on the outside of the bottom of the crushing barrel 1, and then gradually move towards the middle along the inclined surface of the bottom of the crushing barrel 1, and finally enter the lifting cylinder 4. During this process, the ultrasonic generator 6 is started to crush the passing glass powder into even finer ultrafine powder.

[0042] In the second step, while the moving grinding cone 3 is rotating, it will simultaneously drive the spiral feeding rod 5 to rotate. The rotating spiral feeding rod 5 will lift the powder that has entered the lifting cylinder 4 to the top of the lifting cylinder 4, and then discharge it from the top of the lifting cylinder 4. The discharged powder will fall onto the disc 7, and then be sprinkled back onto the edge of the bottom of the crushing barrel 1 along the inclined surface of the top of the disc 7, so that it can pass through the ultrasonic generator 6 again to form a dynamic cycle, so as to fully break the glass into ultrafine powder.

[0043] Third, after the grinding is completed, press down on the pin plate 12 to make it slide downward against the elastic force of the spring 13. Then rotate the grinding barrel 1 to make it tilt and allow the powder in the grinding barrel 1 to be discharged through the opening at the top of the grinding barrel 1. After the powder is discharged, release the grinding barrel 1 to return it to its original position. Then release the pin plate 12. The pin plate 12 will slide upward under the elastic force of the spring 13. The two pins on the spring 13 will be inserted into the pin holes at the bottom of the grinding barrel 1 to fix the position of the grinding barrel 1 and ensure the stability of the grinding barrel 1 during operation.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
