Description

Technical Field

[0001] This utility model relates to the field of fireworks sparkler production technology, specifically to an automatic granulation production system for fireworks sparklers. Background Technology

[0002] The powder used in fireworks granulation is gunpowder, which is a flammable and explosive substance with sensitive chemical properties. A series of factors such as collision, compression, friction, and high temperature during the stirring process may trigger an explosion and cause an accident.

[0003] Firework beads are a type of pyrotechnic raw material widely used in various types of fireworks, including those that produce sparks. The manufacturing process of fireworks beads typically consists of the following steps: dry / wet mixing, granulation, intermediate packaging (coating different gunpowder powders), and outer coating (coating with an outer layer of igniter).

[0004] Currently, the production of sparklers on the market involves sieving the powder using a separate sieving machine, followed by manual handling of the granules to be added to granulation machines. This method is not only inefficient and affects the quality of the finished product, but more importantly, the external powder and granule hoppers are exposed to the air. If workers operate the equipment improperly or become fatigued, sparks may be generated, igniting the powder and causing potentially disastrous consequences.

[0005] Some existing automatic batching equipment, such as belt feeders, are not equipped with weighing and flow control devices, so they cannot effectively control the feeding. Moreover, the material is exposed to the outside through belt conveyor, which increases the risk of accidents due to the large friction. They also lack automatic alcohol and powder addition devices, and do not achieve complete separation of man and machine. Furthermore, they are not equipped with dust monitors and dust removal devices, so they cannot effectively control dust.

[0006] In conclusion, there is an urgent need for an automated granulation production system for fireworks beads to solve the above problems. Utility Model Content

[0035] The feeding and conveying room 10, mixing room 20, crushing and granulation room 30, pelletizing room 40, at least one intermediate packaging room 50, and coating room 60 are separated from each other by walls 101. Materials between adjacent rooms are transferred via transmission pipelines (described in detail later).

[0044] Preferably, the powder mixer 21 includes a dry mixer and a wet mixer. The outlet of the feeding conveying pipe 12 is connected to the inlet of the dry mixer, and the discharge port of the dry mixer is connected to the inlet of the wet mixer. The height of the dry mixer is higher than that of the wet mixer so that the material is transferred by gravity.

[0045] In other embodiments, the powder mixer 21 is a dry-wet mixing integrated machine, in which dry mixing is performed first and then wet mixing is performed, without the need for material transfer between the dry mixing container and the wet mixing container.

[0046] Preferably, in this embodiment, the subsequent working room includes an upper tray room 70, which is equipped with a conveyor belt and multiple trays. The trays are placed on the conveyor belt and receive the coated material conveyed by the vacuum conveying pipe 621 of the fifth vacuum powder feeder 62. The material in the trays can be used for subsequent drying processes.

[0047] Preferably, in this embodiment, a drying chamber 80 is also included, which is located away from the feeding and conveying room 10, the mixing room 20, the crushing and granulation room 30, the pelletizing room 40, at least one intermediate packaging room 50, the coating room 60, the electrical room 91, and the loading tray room 70. The material dried in the drying chamber 80 is very dry and more flammable and explosive than the material during the granulation process; therefore, it needs to be physically located away from other work areas. The material trays after loading into the loading tray room 70 can be transported to the drying chamber via a conveyor belt device. Preferably, the material can be manually transported to the drying chamber 80 for drying using an anti-static trolley.

[0049] Preferably, the feeding and conveying room 10, mixing room 20, crushing and granulation room 30, pelletizing room 40, at least one intermediate packaging room 50, coating room 60, electrical room 91, and upper tray room 70 are all equipped with doors. Preferably, each workroom is equipped with a door, allowing personnel to enter the workroom for operation when needed; normally, personnel are not allowed to enter the workroom during the automatic granulation process of fireworks beads.

[0050] Please combine them together Figure 3 Preferably, a raw material conveying room 93 is also provided outside the intermediate packaging room 50 and the coating room 60. The raw material conveying room 93 is equipped with a hopper 931 and a feeder 932. The hopper 931 contains the corresponding intermediate packaging agent or the ignition agent for coating. Since the intermediate packaging and coating processes require the addition of materials during the bright bead manufacturing process, and these materials are all highly flammable and hazardous items, the raw material conveying room 93 also needs to be separated from other work areas.

[0051] Preferably, each of the intermediate packaging rooms 50 and the medicine wrapping room 60 is further provided with a raw material conveying room 93 outside; or the intermediate packaging rooms 50 and the medicine wrapping room 60 share a single raw material conveying room 93 outside.
