Description
Technical Field
[0001] This utility model relates to the technical field of fireworks production equipment, and in particular to a fireworks dryer. Background Technology
[0002] Fireworks dryers are a key piece of equipment in the manufacturing process of fireworks and firecrackers. They are used to dry the finished fireworks to ensure that the gunpowder, paper tubes, fuses and other materials in the fireworks are stored at a suitable humidity level to achieve the best setting effect and safety.
[0003] There are two existing methods for drying fireworks. The first method is to stack the fireworks and put them into the drying room for centralized drying. The second method is to use a belt conveyor on the production line to transport the fireworks to the dryer for continuous drying. Compared with the first method, the second method can effectively improve drying efficiency and increase fireworks production, but it still has the following problems: the existing drying equipment has a long span and occupies a large area; the existing belt conveyor transports fireworks without turning them over, resulting in poor uniformity in drying.
[0004] Therefore, there is an urgent need for a firework dryer that can occupy a small area and rotate the firework during the drying process. Utility Model Content
[0005] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a firework dryer that can occupy a small area and can rotate the firework during the drying process.
[0006] The technical solution is as follows: A fireworks dryer includes an insulated outer shell, a circulating belt conveyor, a heater, connecting frames, a drying fan, and a turning mechanism. The circulating belt conveyor is located inside the insulated outer shell, and a heater is located on the top of the insulated outer shell. Multiple connecting frames are connected to the upper part of the circulating belt conveyor, and a drying fan is connected to the upper part of each connecting frame. A turning mechanism is located in the middle of the circulating belt conveyor. The fireworks to be dried are driven by the circulating belt conveyor to move in an S-shape from top to bottom inside the insulated outer shell. The heater heats the air, and the heated air is delivered to the inside of the insulated outer shell by the drying fan and blown onto the circulating belt conveyor to dry the fireworks on the circulating belt conveyor.
[0007] Preferably, the upper right part of the insulation shell is the feeding point, and the lower left part of the insulation shell is the discharging point.
[0008] As a preferred option, the circulating belt conveyor is divided into three layers: upper, middle, and lower.
[0009] Preferably, the turning mechanism includes a motor, a rotating frame, a high-pressure nozzle, and connectors. The motor is connected to the front of the middle layer of the circulating belt conveyor, and the rotating frame is rotatably connected to the middle layer of the circulating belt conveyor. The high-pressure nozzle is connected to the upper part of the rotating frame, and connectors are connected to both the front and rear sides of the rotating frame. The connectors are connected to a high-pressure air injection device to inject high-pressure gas into the rotating frame. The high-pressure gas is sprayed out through the high-pressure nozzle to perform a jet operation on the fireworks that have moved to this location. The high-pressure airflow allows the fireworks to roll and turn on the circulating belt conveyor, improving the uniformity of the fireworks drying and preventing the fireworks shells from sticking to the circulating belt conveyor. The motor controls the rotation of the rotating frame, and the rotation of the rotating frame adjusts the spray angle of the high-pressure nozzle, which can adapt to different types of fireworks.
[0010] Preferably, a buffer mechanism is also included. The buffer mechanism includes a mounting frame, a buffer plate, a torsion spring, and a baffle. The mounting frame is connected to the left side of the upper layer and the right side of the middle layer of the circulating belt conveyor. The buffer plate is rotatably connected to the mounting frame. The torsion spring is connected to the mounting frame on both the front and rear sides of the buffer plate. The baffle is connected to the left side of the middle layer and the right side of the lower layer of the circulating belt conveyor. When the upper and middle layers of the circulating belt conveyor transport the fireworks to the end of the moving direction, the buffer plate supports the fireworks and rotates and tilts due to the weight of the fireworks. The fireworks roll off under the action of gravity and after leaving the buffer plate, the torsion spring rebounds and controls the buffer plate to rotate and reset. At the same time, the rolling fireworks are not removed from the circulating belt conveyor due to the influence of the baffle. Under the tilting guidance of the baffle, they generate a reverse rotation force, causing the fireworks to flip over, further improving the uniformity of fireworks drying.
[0011] Preferably, the baffle is an inclined structure.
[0012] The beneficial effects are: 1. This utility model injects high-pressure gas into the rotating frame through a high-pressure gas injection device connected to the connector. The high-pressure gas is sprayed out through a high-pressure nozzle to perform a jet operation on the fireworks that have moved to this location. This allows the dried fireworks to roll and turn over on the circulating belt conveyor, improving the uniformity of the drying of the fireworks and preventing the outer shell of the fireworks from sticking to the circulating belt conveyor.
[0013] 2. This utility model uses a buffer plate to support the fireworks, and the fireworks rotate and tilt due to their weight, causing them to roll down under gravity. The fireworks are also prevented from detaching from the circulating belt by the baffle plate, and the tilting baffle plate generates a reverse rotational force, causing the fireworks to flip. This prevents the fireworks from deforming and being damaged when they fall, and increases the number of times the fireworks are flipped, thus improving the uniformity of the drying process.
[0014] 3. This utility model uses a circulating belt conveyor to drive the fireworks to move in an S-shape from top to bottom inside the insulation shell. The heater heats the air, and the heated air is delivered to the inside of the insulation shell by the drying fan and blown onto the circulating belt conveyor to dry the fireworks on the conveyor. This can effectively save production space. Attached Figure Description

Detailed Implementation
[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] A type of fireworks dryer, such as Figures 1-4 As shown, the device includes an insulated outer shell 1, a circulating belt conveyor 2, a heater 3, a connecting frame 4, a drying fan 5, and a turning mechanism 6. The upper right part of the insulated outer shell 1 is the feeding port, and the lower left part is the discharging port. The circulating belt conveyor 2 is installed inside the insulated outer shell 1. The circulating belt conveyor 2 is divided into three layers: upper, middle, and lower. The upper, middle, and lower layers of the circulating belt conveyor 2 are all hollow structures. The heater 3 is installed at the top of the insulated outer shell 1. Multiple connecting frames 4 are connected to the upper part of the circulating belt conveyor 2. The drying fan 5 is connected to the upper part of each connecting frame 4. The turning mechanism 6 is installed in the middle of the circulating belt conveyor 2. The fireworks that need to be dried are driven by the circulating belt conveyor 2 to move in an S-shape from top to bottom inside the insulated outer shell 1. The heater 3 heats the air, and the heated air is delivered to the inside of the insulated outer shell 1 by the drying fan 5 and blown onto the circulating belt conveyor 2 to dry the fireworks on the circulating belt conveyor 2.
[0022] The flipping mechanism 6 includes a motor 61, a rotating frame 62, a high-pressure nozzle 63, and a connector 64. The motor 61 is connected to the front of the middle layer of the circulating belt conveyor 2. The rotating frame 62 is rotatably connected to the middle layer of the circulating belt conveyor 2. The high-pressure nozzle 63 is connected to the upper part of the rotating frame 62. The connectors 64 are connected to both the front and rear sides of the rotating frame 62. The connectors 64 are connected to a high-pressure air injection device to inject high-pressure gas into the rotating frame 62. The high-pressure gas is sprayed out through the high-pressure nozzle 63 to perform a jet operation on the fireworks that have moved to this location. The high-pressure airflow allows the fireworks to roll and flip on the circulating belt conveyor 2, improving the uniformity of the fireworks drying and preventing the fireworks shells from sticking to the circulating belt conveyor 2. The motor 61 controls the rotation of the rotating frame 62, and the rotation of the rotating frame 62 adjusts the spray angle of the high-pressure nozzle 63, which can adapt to different types of fireworks.
[0023] It also includes a buffer mechanism 7, which includes a mounting frame 71, a buffer plate 72, a torsion spring 73, and a baffle 74. The mounting frame 71 is connected to the left side of the upper layer and the right side of the middle layer of the circulating belt conveyor 2. The buffer plate 72 is rotatably connected to the mounting frame 71. The torsion spring 73 is connected to the mounting frame 71 on both the front and rear sides of the buffer plate 72. The baffle 74 is connected to the left side of the middle layer and the right side of the lower layer of the circulating belt conveyor 2. The baffle 74 is an inclined structure. When the upper and middle layers of the circulating belt conveyor 2 transport the fireworks to the end of the moving direction, the buffer plate 72 supports the fireworks and rotates under the influence of the weight of the fireworks, causing them to tilt. The fireworks roll off under the action of gravity and after they leave the buffer plate 72, the torsion spring 73 rebounds and controls the buffer plate 72 to rotate back to its original position. At the same time, the rolling fireworks are not removed from the circulating belt conveyor 2 due to the influence of the baffle 74. Under the guidance of the inclined baffle 74, they generate a reverse rotation force, causing the fireworks to flip over, further improving the uniformity of the fireworks drying.
[0024] In use, the fireworks to be dried are driven by a circulating belt conveyor 2 to move in an S-shape from top to bottom inside the insulation shell 1. A heater 3 heats the air, which is then delivered to the insulation shell 1 by a drying fan 5 and blown onto the circulating belt conveyor 2 to dry the fireworks. The dried fireworks are then discharged from the circulating belt conveyor 2. Before drying, a high-pressure gas injection device connected to connector 64 injects high-pressure gas into the rotating frame 62. During drying, the high-pressure gas is sprayed out through a high-pressure nozzle 63, jetting the fireworks that have moved to this location. The high-pressure airflow causes the fireworks to roll and turn on the circulating belt conveyor 2, improving the uniformity of drying and preventing... The circulating conveyor belt 2 prevents the fireworks shells from sticking to the conveyor belt. The motor 61 controls the rotation of the rotating frame 62, which adjusts the spray angle of the high-pressure nozzle 63 to adapt to different types of fireworks. When the upper and middle layers of the circulating conveyor belt 2 transport the fireworks to the end of the moving direction, the buffer plate 72 supports the fireworks and rotates due to the weight of the fireworks, causing them to tilt. The fireworks roll off under the action of gravity and, after leaving the buffer plate 72, the torsion spring 73 rebounds and controls the buffer plate 72 to rotate back to its original position. At the same time, the rolling fireworks are affected by the baffle 74 and will not fall off the circulating conveyor belt 2. Under the tilting guidance of the baffle 74, they generate a reverse rotation force, causing the fireworks to flip over, further improving the uniformity of the fireworks drying.
