Description

Technical Field

[0001] This utility model relates to mechanical equipment for crushing raw materials for fireworks and firecrackers, specifically an automated single-base powder crushing and processing line. Background Technology

[0002] Single-base powder is a cylindrical solid material that needs to be processed and crushed before it can be used in fireworks and firecrackers. Currently, the processing and crushing of single-base powder involves manually feeding the raw material into the hopper of a crusher. This method exposes workers to direct contact with the powder, posing certain safety risks. Furthermore, when cylindrical granules are fed into the hopper at a single time, bridging can easily occur at the discharge port, causing uneven feeding and ultimately affecting the production efficiency of the crushing process. Therefore, there is an urgent need for an automated single-base powder crushing and processing equipment that can safely, stably, and evenly feed the powder into the crusher while reducing manual labor.

[0040] When this utility model is in operation, the production line starts, and the worker adds the single-base powder raw material into the raw material storage cylinder 111. Water is added quantitatively through the solenoid valve 114. The mud pump 115 starts and pumps the single-base powder raw material water mixture into the raw material conveying pipe 117 and conveys it to the distribution hopper 1231 of the feeding component 12 of the coarse crushing mechanism 1. After the water mixture is filtered by the perforated plate 1235 in the distribution hopper 1231, it enters the shaftless screw conveyor 122 from the bottom. The shaftless screw conveyor 122 starts and slowly feeds the single-base powder raw material water mixture with excess water into the toothed disc crusher 132 below for coarse crushing. The coarsely crushed water mixture is discharged from the discharge port at the bottom of the toothed disc crusher 132 through the coarse crushing concentrator. The material receiving trough 1412 of the material assembly 14 falls into the coarse crushing collection pool 141. The water filtered out by the distribution hopper 1231 is collected in the water collection space 1236 at the bottom of the box and returned to the raw material storage cylinder 111 through the return water pipe 124. Then, the initial crushed material in the coarse crushing collection pool 141 is extracted by the mud pump 143 and transported through the raw material conveying pipe 1432 to the feeding assembly 21 and the fine crushing assembly 22 of the fine crushing mechanism 2 in the next fine crushing process. By increasing the number of units and reducing the control crushing rate, the fineness of the raw material is ensured. The finely crushed slurry of the single base powder after the fine crushing process is extracted by the mud pump 232 and the conveying pipe of the fine crushing collection assembly 23 to the next dewatering process. If the production capacity is increased, the distribution hoppers 1231 and 1231' of the distribution hopper device 123 in the feeding assembly 12, the two sets of shaftless screw conveyors 122, and the two sets of feeding assemblies 21 and two sets of fine crushing assemblies 22 in the fine crushing mechanism 2 can be started simultaneously.

[0041] In the dewatering process, the finely pulverized slurry is conveyed to the material cylinder 311 through the conveying pipe. At the same time, tap water is added to the material cylinder 311 through the water inlet pipe 313. The stirring motor 315 starts stirring. After the slurry is stirred evenly, the water pump on the discharge pipe 317 starts, and the slurry flows through the discharge pipe 317 to the centrifuge 321. The centrifuge 321 starts to centrifuge and remove the water from the slurry, turning it into powder, which falls through its discharge port onto the water-blocking component 41 of the powder conveying mechanism 4.

[0042] After the single-base powder is dehydrated, the electric cylinder motor 412 of the water-blocking component 41 of the powder conveying mechanism 4 drives the water receiving tray 414 to extend directly below the discharge port of the centrifuge 321. The centrifuge 321 removes the seepage water from the slurry. After the seepage water is completely removed, the water receiving tray 414 returns to its original position. The powder falls into the first conveyor line 42, and the motor 422 drives the conveyor line 42 to transport the powder. The powder falls into the hopper 43 of the second conveyor line 42' along with the first conveyor line 42. The motor 422 of the second conveyor line 42' drives the second conveyor line 42' to transport the powder to the next packaging process.

[0043] In the packaging process, the finely pulverized material falls from the rear end of the powder conveyor mechanism 5 into the screen 513. The motor 518 starts, and the screen 513 moves back and forth to sieve the powder. The vibrating feeder 519 starts, causing the powder to fall from the hopper 512 into the transfer trough 520. When empty, the weighing sensor 5203 starts the vibrating platform 522, causing the powder in the transfer trough 520 to vibrate and fall into the weighing hopper 5202. After sensing the preset weight of the powder, the weighing sensor 5203 controls the vibrating platform 522 to stop operating, and the powder stops falling. At this point, the worker places the material bucket on the conveyor belt 531 at the front end of the conveyor frame 536. The material bucket is conveyed by the conveyor belt 531 to a position directly below the weighing hopper 5202. The positioning detection device 535 senses the material bucket and controls the valve to drive the electric cylinder 5206 to retract, opening the discharge valve 5205 of the weighing hopper 5202. The vibrating feeder 5204 works simultaneously, causing the powder in the weighing hopper 5202 to fall into the material bucket, completing the powder packaging. Because different sizes of material buckets have different heights, to prevent material buckets of different sizes from being placed on the conveyor belt 531, a height detection device 534 can identify material buckets that do not meet the packaging specifications for removal.
