Description

Technical Field

[0001] The invention relates to the technical field of fireworks production, in particular to a gunpowder drying device in fireworks production. Background Art

[0002] Fireworks are a kind of performing arts and entertainment products that produce light, sound and color through rapid combustion and chemical reactions. The main component of fireworks is gunpowder, which is responsible for generating propulsion and explosion effects. The moisture contained in gunpowder will reduce its combustion efficiency and cause changes in the chemical composition of gunpowder, thereby increasing its instability and even causing explosion risks. Gunpowder drying equipment is used to remove moisture and humidity from gunpowder to ensure that the gunpowder maintains optimal performance and safety;

[0003] The gunpowder drying device mainly includes a drying chamber, a heating system and a ventilation system. The drying chamber is the core part of the device, where the gunpowder is placed for drying. The heating system is responsible for heating the air to provide the required heat during the drying process, and the ventilation system is used to ensure the efficiency of the drying process.

[0004] The wind speed of the existing gunpowder drying device cannot be adjusted according to the humidity inside the drying chamber. When the humidity is high, too slow a ventilation speed cannot effectively take away the evaporated moisture; when the humidity is low, too fast a ventilation speed cannot stably maintain the heat, thereby reducing the drying effect and resulting in low drying efficiency. Summary of the invention

[0008] The cam is an angular movement ...

[0009] A connecting block is fixedly connected to the bottom of the movable plate, and the outer wall of the connecting block is slidably connected to the inside of the drying chamber. A rotating shaft 1 is rotatably connected to one side of the inside of the connecting block, and a bevel gear 1, a bevel gear 2 and a rotating blade are fixedly connected to the outer wall of the rotating shaft 1. A motor is fixedly connected to the bottom of one side of the drying chamber, and a driving end of the motor is fixedly connected to the rotating shaft 2. A bevel gear 3 and a bevel gear 4 are fixedly connected to the outer wall of the rotating shaft 2. The bevel gear 3 is meshed with the bevel gear 2, and the bevel gear 4 is meshed with the bevel gear 2. Evenly distributed ventilation openings are provided inside the drying chamber.

[0010] Preferably, an electric push rod is fixedly connected to the inner top side of the drying chamber, a pressing block is fixedly connected to the telescopic end of the electric push rod, the bottom of the pressing block abuts against the top of the sponge, and the outer wall of the pressing block is slidably connected to the inside of the lifting block.

[0011] Preferably, a check valve is installed on the outer wall of the drain pipe, and the outer wall of the drain pipe is fixedly connected to the inner rear side of the drying chamber.

[0012] Preferably, the interior of the drain pipe is fixedly connected with evenly distributed support blocks, the top of the support block abuts against the bottom of the lifting block, and the spring is sleeved on the outer wall of the support block.

[0013] Preferably, a slider 1 is fixedly connected to both the front and rear sides of the movable plate, and the outer wall of the slider 1 is slidably connected to the interior of the drying chamber.

[0014] Preferably, both the front and rear sides of the slide plate 1 are fixedly connected with a slide block 2, and the outer wall of the slide block 2 is slidably connected to the inside of the fixed plate.

[0015] Preferably, both the front and rear sides of the slide plate 2 are fixedly connected with a slide block 3, and the outer wall of the slide block 3 is slidably connected to the inside of the movable plate.

[0016] Preferably, one end of the rotating shaft away from the rotating blade is fixedly connected to a limiting plate, and an outer wall of the limiting plate is rotatably connected to the inside of the connecting block.

[0017] Preferably, a handle is installed on the front side of the chamber door, and a door lock is installed on the front side of the drying chamber.

[0018] Preferably, the bottom of the drying chamber is fixedly connected with evenly distributed support rods.

[0019] Working principle: By turning the handle, the restriction of the door lock on the door can be released. After the restriction is released, the door can be driven to rotate through the hinge to open the drying chamber. By pulling the pull block, the placement plate can be moved on the top of the heating plate. After the placement plate is pulled out, the gunpowder is placed on the placement plate and pushed back. Then the chamber door is closed and locked by the door lock, so that the inside of the device is sealed. The gunpowder inside the placement plate is dried by the heating plate. At the same time, starting the motor can drive shaft two to rotate. Shaft two can drive bevel gear three to rotate by rotation. Bevel gear three can drive bevel gear two to rotate by rotation. Bevel gear two can drive shaft one to rotate by rotation. Shaft one can drive rotating blades to rotate. The rotating blades can make the air inside the drying chamber circulate through the vents. During the air flow, the moisture in the air can be absorbed by the sponge, thereby providing a drier environment and accelerating the drying of the gunpowder. During the circulation drying process, moisture is absorbed by the sponge and finally discharged from the drying chamber through the drain hole. Due to the absorption of the sponge Water will increase the weight, thereby driving the lifting block to descend. The lifting block can drive the rotating plate 1 to rotate by descending, and then drive the moving block to move. The moving block can drive the lifting rod to lift by moving. The lifting rod can drive the slide plate 1 to move by lifting. The movement of the slide plate can drive the moving plate to move through the hinge. The movement of the moving plate can drive the rotating shaft 1 to move through the connecting block. The rotating shaft 1 can release the meshing of the bevel gear 2 and the bevel gear 3 by moving, and make the bevel gear 1 and the bevel gear 4 mesh, thereby slowing down the rotation speed of the rotating shaft 2, so as to increase the ventilation speed when the humidity is high, which helps to quickly take away the evaporated moisture; and when the air humidity decreases, the ventilation speed is reduced to maintain heat, optimize the drying effect, and ensure the efficiency of the drying process. After drying is completed, the electric push rod drives the pressing block to descend to squeeze out the moisture inside the sponge. During the extrusion process, the support block can prevent damage to the spring. The squeezed moisture flows into the fixed block through the drainage hole and is discharged again through the drainage pipe, so that the device returns to the initial position for the next drying.

[0020] The present invention provides a gunpowder drying device for fireworks production, which has the following beneficial effects:

[0021] 1. The present invention can absorb moisture in the air through the sponge, and after absorbing moisture, the weight of the sponge can be increased, and a labor-saving structure is formed by the rotating plate 1, the rotating plate 2, the moving block and the lifting rod, so as to amplify the gravity, and then the moving distance is amplified by the hinge, and finally the connecting block is driven to move. The connecting block can slow down the rotation speed of the rotating blades by moving, so as to achieve rapid ventilation to take away the evaporated moisture when the air humidity is high; and when the air humidity drops, the ventilation speed is reduced to maintain heat, optimize the drying effect, and ensure the efficiency of the drying process.

[0022] 2. The present invention drives the pressing block to move downward by an electric push rod, thereby squeezing out the moisture in the sponge. In this process, the spring can be protected from damage by the support block. The squeezed moisture will flow into the interior of the fixed block through the drainage hole and then be discharged through the drainage pipe, ensuring that the device can be reset and ready for the next drying. A check valve is provided in the drainage pipe to prevent external air from entering the interior of the device and affecting the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
