Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to a fireworks powder safety feeding and mixing device. Background Art

[0002] The manufacturing process of fireworks powder involves several key steps, with adding and mixing being crucial. Traditional methods of adding and mixing rely primarily on mechanical equipment. However, these traditional devices present serious safety hazards in practical applications, primarily in the following areas:

[0003] (1) Frictional heat generated by mechanical stirring: Conventional mixing equipment typically uses mechanical stirring. During the stirring process, friction between the stirring blades and the gunpowder generates heat. Due to the physical properties of gunpowder, this heat accumulation may cause the gunpowder to spontaneously ignite, or even cause a fire or explosion, posing a threat to the safety of operators and the safety of the equipment.

[0004] (2) Inadequate heat dissipation performance of the equipment: If the heat generated during the mixing process cannot be dissipated in time, it will further increase the temperature of the gunpowder, increasing the risk of fire and explosion. However, many traditional mixing equipment are not adequately designed for heat dissipation. The heat dissipation effect of the equipment's outer wall is poor, which cannot effectively reduce the temperature inside the equipment, further increasing the risk of operation.

[0005] In summary, existing fireworks powder feeding and mixing equipment has shortcomings in terms of safety, which restricts the safety of fireworks powder production. In order to solve these problems, the development of a safer fireworks powder feeding and mixing device with higher safety has become an urgent need in the industry. Utility Model Content

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0029] Example 1:

[0030] See also Figure 1 - Figure 6 In this embodiment, a fireworks gunpowder safety feeding and mixing device is provided, which is specifically used for the safe feeding and mixing of fireworks gunpowder, and specifically includes: a mixing module 1, which is used for mixing gunpowder raw materials; a feeding module 2, which is used to store a variety of gunpowder raw materials and transport the raw materials to the mixing module 1; the mixing module 1 includes a mixing bin 11 and a cooling bin 12, the mixing bin 11 is installed on the vertical lifting module 5 and is suitable for being driven by a driving motor 13 to rotate, and circulating cooling water is introduced into the cooling bin 12.

[0031] Specifically, in the present embodiment, the gunpowder raw materials of different components are transported to the mixing bin 11 of the mixing module 1 through the feeding module 2. The mixing bin 11 adopts a cylindrical structure design, which is driven to rotate by the driving motor 13. Under the action of centrifugal force, the gunpowder raw materials are quickly and evenly mixed. This design avoids the direct friction between the stirring blades and the gunpowder raw materials during the traditional mechanical stirring process, thereby reducing the risk of spontaneous combustion caused by the heat generated by friction. In order to further improve safety, a cooling system is used to control the temperature during the mixing process. The mixing bin 11 is located in a larger cooling bin 12, and the cooling bin 12 is filled with circulating cooling water. When the internal temperature of the mixing bin 11 rises, the vertical lifting module 5 will lower the mixing bin 11 into the cooling water, and quickly take away the heat through the heat conduction effect of the water. The cooling water circulates through the cooling pipe, continuously taking away the heat generated during the mixing process. In addition, the cooling system is equipped with a temperature sensor and a control valve, which can monitor the cooling water temperature in real time and adjust the cooling water flow rate to ensure that the internal temperature of the mixing bin 11 is always maintained within a preset safety range, effectively preventing the spontaneous combustion or explosion of gunpowder due to overheating. In terms of material selection, the mixing bin 11 is made of explosion-proof materials with high impact resistance and heat resistance, which effectively prevents the explosion of gunpowder during the mixing process. Specifically, high-strength alloy steel or special composite materials can be selected as explosion-proof materials to meet safety and durability requirements. Through the design of the above structure, the utility model reduces the safety risks in the production process and is suitable for fireworks production companies of various sizes. It can be adjusted and optimized accordingly according to different production needs.

[0032] The feeding module 2 includes a plurality of hoppers 21, each hopper 21 is used to store different types or batches of gunpowder raw materials. Figure 6 An electric valve 22 is provided at the connection between the hopper 21 and the feeding pipe 23. By opening and closing the electric valve 22, the quantitative feeding of the gunpowder raw materials is ensured, avoiding the safety hazards caused by excessive feeding. The feeding pipe 23 is used to transport the gunpowder raw materials from the hopper 21 to the mixing bin 11. The inside of the feeding pipe 23 is provided with an anti-static coating to prevent the gunpowder raw materials from exploding due to static electricity accumulation during the transportation process. An air amplifier 24 is installed on the feeding pipe 23. The air amplifier 24 pushes the gunpowder raw materials to the mixing bin 11 through airflow, reducing the static electricity generated by friction during the mechanical (screw) transportation process.

[0033] See also Figure 3 and Figure 4A protective cover 3 is installed on the mixing bin 11. The protective cover 3 is connected to the inner bottom surface of the mixing bin 11 via a telescopic component 31. The telescopic component 31 is used to open and close the protective cover 3, making it convenient to open the protective cover 3 when adding materials and close it when mixing. The telescopic component 31 is a cylinder, and the protective cover 3 is equipped with a pressure sensor 32 for monitoring the pressure inside the mixing bin 11. When the pressure inside the mixing bin 11 exceeds a preset safety value, the drive motor 13 is stopped (the pressure sensor 32 sends a signal to the control system, which automatically stops the drive motor 13) to ensure the safety of the mixing process.

[0034] See also Figure 4 and Figure 5 The outer wall of the mixing bin 11 is provided with a heat dissipation component 4, which is composed of a number of heat dissipation fins 41 arranged in a staggered and stacked manner. The heat dissipation fins 41 adopt a fan-shaped structure, and the height gradually increases from the root connected to the outer wall of the mixing bin 11 from the inside to the outside. The fins are provided with drainage holes 42 at the root. When the vertical lifting mechanism lifts the mixing bin 11 as a whole and separates it from the cooling bin 12, the residual cooling water on the heat dissipation fins 41 is discharged through the drainage holes 42. Through this design, the heat dissipation area is increased. During the rotation of the mixing bin 11, the heat dissipation fins 41 form convection and full contact with the cooling water, which effectively improves the heat dissipation efficiency and ensures that the temperature of the outer wall of the mixing bin 11 will not be too high.

[0035] The mixing bin 11 is installed on the vertical lifting module 5. The vertical lifting includes two columns 51. A crossbeam 52 is provided between the two columns 51 for vertical sliding. The mixing bin 11 and its drive motor 13 are both installed on the crossbeam 52. A hydraulic cylinder 53 is provided on the column 51 to drive the crossbeam 52 to rise and fall. The lifting operation of the mixing bin 11 is achieved by the extension and retraction of the hydraulic cylinder 53, which makes the feeding and mixing process more flexible and convenient, and improves production efficiency.

[0036] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
