Description

Technical Field

[0001] This application relates to the field of fireworks equipment technology, specifically to a bright bead granulation and screening device. Background Technology

[0002] Bright beads are a relatively large-scale product in fireworks production. They are made by coating the core with powdered chemicals and then rotating it in a high-speed granulator. Generally, the coating powder consists of functional powder and igniter powder. First, the functional powder is mixed and coated on the core to form premixed granules. Then, the premixed granules are mixed with the igniter powder, coated with the chemical powder, and rotated to form bright bead granules.

[0003] To ensure the quality of the glitter beads after granulation, the premixed granules need to be screened. Defective premixed granules with excessively large dimensions must be removed. Using these defective premixed granules in the next granulation step will result in larger final glitter beads, affecting subsequent filling. Furthermore, larger dimensions also indicate an excessive amount of functional powder coating the bead core, which will inevitably impact the final flare effect. Additionally, the premixed granules may contain small clumps or fragments, which also need to be screened to prevent these clumps or fragments from entering the next granulation step and affecting the quality of the glitter beads.

[0004] Currently, during the granulation process of bright beads, defective products, clumps, and fragments are typically collected in small quantities and then pulverized and reused after accumulating to a certain amount. However, long-term storage of defective products, clumps, and fragments poses significant safety risks. Furthermore, the types of functional powders contained in the premixed granules of different bright bead models vary, and defective products, clumps, and fragments may become damp during long-term storage. Therefore, recycling stored defective products, clumps, and fragments can also affect the quality of the bright beads. Utility Model Content

[0043] As attached Figure 1-4 As shown, this application provides a bright bead granulation and screening device through the following technical solution, including:

[0044] Upper screen body 2 is inclined and has a first discharge port 21;

[0045] The crushing device 6 is located below the first discharge port 21 and has a second discharge port 61; the lower trough 5 is inclinedly located below the upper screen body 2 and has a third discharge port 51.

[0046] The recycling unit is located at the third discharge port 51;

[0047] The material screened out of the upper screen body 2 falls into the crushing device 6 through the first discharge port 21, is crushed, falls into the lower tank body 5 through the second discharge port 61, and finally enters the recycling unit through the third discharge port 51.

[0048] Compared with the prior art, this application has the following advantages: a crushing device is set at the first discharge port of the upper screen body of the screening equipment to screen out and crush larger defective products, realizing online real-time crushing of defective products. After crushing, the defective products fall into the lower tank and enter the recycling unit through the third discharge port. The recycling unit collects and reuses them in real time, reducing the safety risks caused by long-term accumulation of defective products and avoiding the impact of centralized recycling of defective products on the quality of bright beads.

[0049] In the technical solution applied in this embodiment, the crushing device 6 includes a driving assembly 62 and a crushing assembly 63. The crushing assembly 63 includes a crushing chamber 631 with an opening 632 at the top. A crushing element is disposed inside the crushing chamber 631, and a second discharge port 61 is disposed at the bottom of the crushing chamber 631. The crushing element is drivenly connected to the driving assembly 62. The crushing element includes a pair of symmetrically arranged circular rollers 633. The circular rollers 633 rotate in opposite directions around their respective axes under the drive of the driving assembly 62, and there is a first gap between the circular rollers 633, which is 1-5 mm.

[0050] An upper trough 4 and a lower trough 3 are also provided between the upper sieve body 2 and the lower trough body 5. The upper trough body 4 and the lower sieve body 3 are both inclined. The upper trough body 4 is located between the upper sieve body 2 and the lower sieve body 3 and is connected end to end with the upper sieve body 2 and the lower sieve body 3. The crushing device 6 is set on the upper trough body 4 below the first discharge port 21. The lower trough body 5 is located below the lower sieve body 3. The aperture of the screen hole of the lower sieve body 3 is smaller than the aperture of the screen hole of the upper sieve body 2.

[0051] After the premixed particles are granulated using the granulator 8, they are fed into the upper screen body 2 through the feed inlet 22. The aperture of the screen holes in the upper screen body 2 is comparable to the outer dimensions of the qualified premixed particles, so that the defective premixed particles with an outer dimensions larger than the qualified size will not fall through the screen holes of the upper screen body 2, but will slide down the inclined surface of the upper screen body 2 to the first discharge port 21, and fall from the first discharge port 21 through the opening 632 onto the circular roller 633 in the crushing chamber 631. As the circular roller 633 rotates in opposite directions under the drive of the drive assembly 62, the defective particles that fall in are carried into the first gap of the circular roller 633, crushed and crushed and fall into the bottom of the crushing chamber 631, and fall into the lower trough body 5 through the second discharge port 61.

[0052] Other premixed particles with acceptable dimensions, along with a small amount of powder lumps and fragments, leak from the sieve holes of the upper sieve body 2 into the upper tank body 4.

[0053] The premixed particles, lumps, and fragments that leak onto the upper tank 4 continue to slide down the inclined surface of the upper tank 4 to the lower screen 3. The aperture of the screen in the lower screen 3 is smaller than that of the screen in the upper screen 2, that is, smaller than the size of the qualified premixed particles. This prevents the qualified premixed particles from leaking through the screen in the lower screen 3, but instead allows them to slide down the inclined surface of the lower screen 3 to the fourth discharge port 31. At the same time, the lumps and fragments carried by the premixed particles will leak down through the screen in the lower screen 3 to the lower tank 5. At this point, these lumps and fragments, along with the defective crushed material that falls into the lower tank 5 through the second discharge port 61, gather together and slide down the inclined surface of the lower tank 5 to the third discharge port 51.

[0054] Specifically, a finished product hopper 32 is provided below the fourth discharge port 31 for collecting premixed granules with acceptable dimensions, and a recycling unit is provided at the third discharge port 51. In this embodiment, the recycling unit includes a recycling hopper 52 and a transfer device 9. The recycling hopper 52 is used to collect defective crushed material, lumps, and fragments, while the transfer device 9 picks up the defective crushed material, lumps, and fragments and puts them back into the granulator 8.

[0055] The qualified premixed granules in the finished product hopper 32 are added to the granulator 8, and ignition powder is added to complete the granulation of the bright beads. When the granulation is completed and the next granulation begins, the transfer device 9 first takes out the powdery mixture containing defective crushed material, lumps, and fragments from the return hopper 52, weighs it, and adds it to the granulator 8. The system or a person calculates the weight of the functional powder to be added based on the weight of the added powdery mixture, so that the total weight of the two is consistent with the normal weight of the functional powder added. Then, the granulation of the premixed granules can begin again. This allows for the real-time reuse of large-sized defective premixed granules, lumps, and fragments, which reduces the safety risks caused by the long-term accumulation of such defective products and avoids the impact of concentrated reuse of defective products on the quality of the bright beads.

[0056] It should be noted that in this embodiment, the drive assembly 62 uses a hydraulic motor, which can provide a stable driving force to the rollers 633. The drive assembly 62 also includes a gear set (not shown in the figure) to convert the unidirectional rotation of the hydraulic motor into the counter-rotation of the pair of rollers 633. The rollers 633 have a first gap of 1-5mm, which can ensure that the pulverized defective products have a small particle size and can be uniformly mixed with the added functional drug powder.

[0057] In the technical solution applied in this embodiment, the bright bead granulation and screening equipment also includes a frame 1 and a base 7. The upper screen body 2, the lower screen body 3, the upper tank body 4 and the lower tank body 5 are all arranged on the frame 1, and the frame 1 is arranged on the base 7. A spring 71 is arranged between the frame 1 and the base 7. A pneumatic vibration device 11 is also provided at the bottom of the frame 1. The pneumatic vibration device 11 drives the frame 1 to achieve elastic vibration on the base 7.

[0058] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
