Description

Technical Field

[0001] This application relates to the field of glass manufacturing technology, and more specifically, to a broken glass sorting device. Background Technology

Pharmaceutical glass possesses numerous superior properties, exhibiting significant advantages in chemical stability, strength, heat resistance, appearance, and cost, making it an irreplaceable packaging container for certain pharmaceutical products and biological agents. The production of these pharmaceutical containers necessitates the manufacture of borosilicate glass tubing that meets the requirements of pharmaceutical packaging.

[0003] Taking borosilicate glass as an example, the raw materials involved in its production include potassium carbonate, industrial salt, quartz sand, borax, sodium hydroxide, and cullet, among others.

Cullet, as a crucial component of the main raw material, directly impacts the melting energy consumption, melting quality, and physicochemical stability of the finished product due to its density, weight, particle size, and cleanliness. Through repeated production, it has been found that the scientific particle size distribution of cullet directly affects production costs, the utilization of limited resources, and the quality and yield of the final product in borosilicate glass production. Existing simple vibrating screens are insufficient for effectively separating the particle size of cullet, thus impacting the production efficiency and quality of borosilicate glass tubes.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0030] The primary function of pharmaceutical packaging is to ensure the quality and stability of various components of medicines. Pharmaceutical glass, with its excellent water resistance, heat and cold resistance, barrier properties, and mechanical properties, is widely used in various reagent and tablet packaging. Medium borosilicate and high borosilicate glass exhibit the best performance. However, the production quality of borosilicate glass is closely related to the particle size of the cullet raw materials used. This application proposes a cullet sorting device for classifying cullet raw materials by particle size to meet the particle size distribution requirements of borosilicate glass production. Figures 1 to 3 An embodiment of the glass sorting apparatus of this application is illustrated schematically.

[0031] like Figures 1 to 3 As shown, this application discloses a broken glass sorting device, which includes: a homogenizing primary screening mechanism and a mixing fine screening mechanism, such as... Figure 1 As shown, the homogenization and primary screening mechanism includes a hopper 1 and a centrifuge 2. The hopper 1 is equipped with a rotating hopper 11 (see...). Figure 2 The centrifuge drum 2 has a first compressed air inlet 12 and a first compressed air outlet 13, with the first compressed air outlet 13 connected to the feed end. Figure 3 As shown, the mixing and screening mechanism includes a mixing chamber 3, a siphon chamber 4, and a settling chamber 5. The feed end of the mixing chamber 3 is connected to the discharge end of the centrifuge 2. The siphon chamber 4 is connected between the mixing chamber 3 and the settling chamber 5. The settling chamber 5 is divided into multiple settling chambers.

[0032] As can be seen from the above, this application, with the help of the above-mentioned structural setting, can use a rotary pressurization method to homogenize and blow glass particles through the hopper 1, so that they enter the centrifuge 2 for rotational separation, thereby initially screening large glass particles, while medium and small particles and dust-like glass microparticles enter the mixing and fine screening mechanism after centrifugation for further mixing and sedimentation separation, so as to achieve the sorting of glass particles of different sizes. This embodiment has the advantages of convenient screening and high particle size classification, which can improve the particle size sorting efficiency and sorting quality, and is conducive to the subsequent use of glass of different particle sizes as examples to produce corresponding glass products. It can comprehensively control various factors in the process of generating broken glass, thereby improving product quality, reducing energy consumption, and maximizing the utilization of raw material resources.

[0033] In some embodiments of this application, such as Figure 2 As shown, the rotating hopper 11 of the hopper bin 1 includes a rotating shaft 111 and a rotating body 112. The rotating body 112 is mounted on the rotating shaft 111 and driven to rotate by the rotating shaft 111. The outer surface of the rotating body 112 is provided with multiple grooves. The rotating body 112 uses these grooves to drive the glass particles to rotate, mix, and homogenize. At the same time, the rotation of the rotating body 112 can also achieve a certain degree of crushing of the glass particles, causing larger particles or glass particles that are stuck together to disperse into smaller particles, providing more raw materials that meet the particle size requirements for borosilicate glass production.

[0034] In some embodiments of this application, reference continues to be made to Figure 2 As shown, within the hopper 1, the rotating body 112 is surrounded by layered dust-collecting grids 14 made of sheet metal. The sheet metal used for the dust-collecting grids 14 is, for example, tempered glass, which has strong wear resistance. The dust-collecting grids 14 guide compressed air to form a reciprocating airflow. Thus, the hopper 1 of this application achieves glass particle homogenization based on a rotating feeding method, and improves the mixing uniformity of the glass particles by adding compressed air to form a reciprocating airflow. The pressurized glass particles are pushed into the centrifuge 2 by the airflow. Through centrifugation within the centrifuge 2, large glass particles (sinking and accumulating) and small and medium-sized and dusty glass particles discharged with the compressed airflow (rising and discharging) are screened out. The small and medium-sized and dusty glass particles then further enter a mixing and fine screening mechanism for particle size separation and collection.

[0035] In some embodiments of this application, such as Figure 2 As shown, the hopper 1 includes a metal shell 15, and a first heat-insulating film 16 is provided on the outside of the metal shell 15. The metal shell 15 can form an effective protection for the rotating hopper 11 and improve safety performance. The first heat-insulating film 16 is used to control the shell temperature of the hopper 1.

[0036] In some embodiments of this application, reference continues to be made to Figure 2As shown, a noise reduction layer 17 is also provided inside the hopper 1, between the dust grid 14 and the metal shell 15. The noise reduction layer 17 includes a polyurethane frame 172 surrounding the outside of the dust grid 14 and a polytetrafluoroethylene plate 171 attached to the inside of the polyurethane frame 172. The multi-layered noise reduction layer 17 can reduce the vibration noise generated by the hopper 1, making it have lower operating noise compared to the vibrating screens commonly used in the prior art, thereby improving the on-site environment and protecting the health of production personnel.

[0037] In some embodiments of this application, such as Figure 1 As shown, the first compressed air outlet 13 of the hopper 1 is tangentially arranged to the inner wall 21 of the centrifuge 2, so that the homogenized glass particles are more easily pushed into the centrifuge 2 by compressed air and centrifuged along the inner wall 21 of the centrifuge 2. Furthermore, in this embodiment, the centrifuge 2 is also provided with a second compressed air inlet 22 and a second compressed air outlet (not shown). The second compressed air inlet 22 is located at the bottom of the centrifuge 2, and the second compressed air outlet is connected to the mixing chamber 3. The centrifuge 2 can introduce new compressed air through the second compressed air inlet 22 to quickly blow small and medium-sized and micro-dust-type glass particles out of the centrifuge 2 and into the mixing and fine screening mechanism for further subdivision. Simultaneously, supplementing the bottom of the centrifuge 2 with compressed air can also increase the airflow within the chamber, thereby retaining as much usable glass particle raw material as possible within the particle size range and improving the utilization rate of the glass particle material.

[0038] In some embodiments of this application, such as Figure 3 As shown, the inner cavity of the mixing chamber 3 has a semi-cylindrical structure. A sand inlet 31 is located at the top of the semi-cylindrical structure, connecting to the discharge end of the centrifuge tank 2 to receive small and medium-sized glass particles and micro-dust particles from the centrifuge tank 2. The mixing chamber 3 also has a third compressed air inlet 32 ​​and a third compressed air outlet 33. The third compressed air inlet 32 ​​is located on the bottom surface of the mixing chamber 3, and the third compressed air outlet 33 is located on the side surface of the mixing chamber 3. The third compressed air outlet 33 is connected to the side feed end of the siphon chamber 4 via a transmission pipe. The third compressed air inlet 32 ​​can blow air upwards in a point-like manner to create a circulating airflow through the arched top of the inner cavity, causing the glass particles in the mixing chamber 3 to flow and mix thoroughly and evenly. Finally, the air flows out from the side third compressed air outlet 33 and enters the siphon chamber 4.

[0039] In this embodiment, baffles are provided between the mixing chamber 3 and the centrifuge tank 2, and between the mixing chamber 3 and the siphon chamber 4. Additionally, the mixing chamber 3 is equipped with a weight sensor. When the mixing chamber 3 is fed, the baffle between the mixing chamber 3 and the centrifuge tank 2 opens, and the baffle between the mixing chamber 3 and the siphon chamber 4 closes. The weight sensor detects the weight of the fed material. When the weight sensor detects that the feeding amount has reached a preset weight, feeding ends, the baffle between the mixing chamber 3 and the centrifuge tank 2 closes, and the baffle between the mixing chamber 3 and the siphon chamber 4 opens. Simultaneously, compressed air is pumped in through the third compressed air inlet 32, initiating the fine screening process. By setting up baffles and weight sensors, relative isolation and sealing can be achieved between centrifuge tank 2 and mixing chamber 3, and between mixing chamber 3 and siphon chamber 4, in order to adjust the problem of inconsistent production pace between the front and back end equipment (for example, for the same batch of crushed glass raw materials, the homogenization primary screening process and the mixing fine screening process may take different times, and therefore cannot be seamlessly connected). Therefore, by using baffles to achieve isolation and sealing between each chamber, the production pace can be adjusted, thereby providing a buffer between different production equipment.

[0040] In some embodiments of this application, such as Figure 3 As shown, the siphon chamber 4 is equipped with a fourth compressed air inlet 41 and a fourth compressed air outlet 42. The fourth compressed air inlet 41 is located on the bottom surface of the siphon chamber 4, and the fourth compressed air outlet 42 is located on the top surface of the siphon chamber 4. The fourth compressed air outlet 42 is horizontally connected to the side feed end of the settling chamber 5 after being bent through a transmission pipe. (Reference) Figure 3 As can be seen, the fourth compressed air inlet 41 and the fourth compressed air outlet 42 are positioned opposite each other. Therefore, the direction of the newly entering compressed air in the siphon chamber 4 is perpendicular to the direction of the feed material flow. This allows the newly entering compressed air to drive the feed material flow rapidly upward, flowing towards the settling chamber 5 at a predetermined speed to achieve particle size sedimentation and classification. In this embodiment, by setting the siphon chamber 4, the speed at which glass particles enter the settling chamber 5 with the airflow can be more precisely controlled, thereby accurately controlling particle size separation. At the same time, the siphon chamber 4 also has a buffering function, which can adjust the difference between the settling speed of the settling chamber 5 and the mixing speed of the mixing chamber 3, avoiding crosstalk between the material airflow at the rear and the front.

[0041] In some embodiments of this application, such as Figure 3As shown, multiple sets of baffles 51 are arranged sequentially along a straight line inside the settling chamber 5. Each baffle 51 has aligned central holes 511, dividing the settling chamber 5 into multiple interconnected settling chambers. An exhaust port 52 is located at the end of the settling chamber. Based on the principle of settling, glass particles of different sizes have different weights and different abilities to move with the airflow, thus their settling areas differ. When the material airflow passes through the central holes 511 of each baffle 51, larger glass particles will be blocked by the baffle 51 first due to their faster descent speed, thereby collecting glass particles of the same size together. In this way, by setting multiple sets of baffles 51 with central holes 511, small and medium-sized glass particles and micro-dust particles can be screened according to their particle size and stored separately in different settling chambers to achieve particle size classification.

[0042] In some embodiments of this application, such as Figure 3 As shown, each settling chamber is equipped with a discharge funnel 53 at the bottom to facilitate the subsequent removal of glass particles of various sizes.

[0043] In some embodiments of this application, such as Figure 3 As shown, the settling chamber 5 also includes a fiberglass shell 54, and a second insulation film 55 is provided on the outside of the fiberglass shell 54. Fiberglass refers to fiber-reinforced plastic, which has the advantages of being lightweight and high-strength, and can be used to make the outer shell of the settling chamber 5, which is designed for low-impact applications. The second insulation film 55 can control the temperature of the settling chamber 5 to meet production requirements.

[0044] In summary, the glass crushing device of this application includes a homogenizing primary screening mechanism and a mixing and fine screening mechanism. The homogenizing primary screening mechanism includes a hopper and a centrifuge. The hopper is equipped with a rotating hopper, a first compressed air inlet, and a first compressed air outlet. The first compressed air outlet is connected to the feed end of the centrifuge. The mixing and fine screening mechanism includes a mixing chamber, a siphon chamber, and a settling chamber connected in sequence. The feed end of the mixing chamber is connected to the discharge end of the centrifuge. The siphon chamber is connected between the mixing chamber and the settling chamber. The settling chamber is divided into multiple settling chambers. This application utilizes a rotary pressurization method to homogenize and blow glass particles through the hopper, causing them to enter the centrifuge for rotational separation. This achieves primary screening of large glass particles, while small and medium-sized particles and dust-like glass microparticles enter the mixing and fine screening mechanism for further mixing and settling after centrifugation. This enables the sorting of glass particles of different sizes, offering advantages such as convenient particle size screening and high particle size classification levels. It also facilitates the subsequent use of glass crushing raw materials of different particle sizes for production proportioning, improving sorting efficiency and quality.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
