Description

Technical Field

[0001] This utility model belongs to the field of hazardous and explosive materials handling technology, and more specifically, it relates to a fireworks and firecrackers destruction device. Background Technology

[0002] During the production, transportation, storage, and setting off of fireworks and firecrackers, waste fireworks and firecrackers or substandard products are generated. These fireworks and firecrackers still contain flammable and explosive components such as gunpowder and fuses. If not handled properly, they can easily cause safety accidents such as fires and explosions. Furthermore, the chemical substances in them can seep into the soil and water sources, causing serious pollution to the ecological environment. At the same time, the large amount of solid residue will also increase the difficulty and cost of waste disposal. Therefore, the safe, efficient, and environmentally friendly harmless treatment of waste fireworks and firecrackers has become an important issue that urgently needs to be addressed.

[0003] Currently, the disposal of discarded fireworks and firecrackers mainly involves incineration and landfill. While incineration can destroy the flammable and explosive components of fireworks and firecrackers to some extent, it releases large amounts of harmful gases (such as sulfur dioxide and nitrogen oxides) during the process, causing air pollution. Furthermore, the high temperatures and flames during incineration may trigger secondary explosions of unburned materials, posing a significant safety hazard. Landfilling, on the other hand, cannot eliminate the potential dangers of fireworks and firecrackers. The chemical substances they contain will slowly seep into the ground, polluting the soil and groundwater, causing far-reaching harm to the ecological environment in the long term. Simple dismantling mainly relies on manual operation, which is not only inefficient and unable to meet the needs of large-scale processing, but also carries extremely high safety risks due to direct contact with flammable and explosive components.

[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figures 1 to 5 The present invention provides a description of the fireworks and firecrackers destruction device. The device includes a crushing system and a spraying system. The crushing system comprises multiple crushing structures and several conveying structures. The crushing structures are arranged sequentially at intervals, and the particle size of the crushed components gradually decreases from upstream to downstream. The conveying structures are located between adjacent crushing structures to connect them. Each crushing structure includes a crushing box 30, a set of crushing rollers 31, and a crushing motor. The upper end of the crushing box 30 has a feed inlet, and the lower end has a discharge outlet. The set of crushing rollers 31 is horizontally arranged within the cavity of the crushing box 30. The set includes two parallel crushing rollers 31, and crushing teeth 32 are provided on the outer periphery of each roller. The set of crushing rollers 31 is connected to the crushing motor. The spraying system includes multiple spray pipes, each corresponding to one of the crushing structures' cavities. Each spray pipe has a nozzle facing the set of crushing rollers 31, and the water inlet of the spray pipe is connected to a water source via a pipe.

[0020] The fireworks and firecrackers destruction device provided by this utility model adopts a multi-stage crushing method. It achieves step-by-step crushing by cooperating with multiple crushing structures that successively reduce the particle size and conveying structures.

[0021] During the crushing process, water is sprayed first, and then the crushing motor is started. Then, the waste fireworks and firecrackers (hereinafter referred to as materials) are fed into the first crushing box 30 from the feed port of the upstream crushing structure. The crushing motor drives the crushing rollers 31 in the crushing box 30 to rotate. The crushing teeth 32 on the outer periphery of the two crushing rollers 31 crush the material for the first time, initially reducing the volume of the material.

[0022] The material after initial crushing is discharged from the outlet of the first crushing structure and transported to the next crushing structure by the adjacent conveyor structure. The particle size of the downstream crushing structures will decrease sequentially, and the material will undergo secondary and tertiary crushing until it reaches the set fine particle state.

[0023] During the crushing process, the crushing box 30 prevents material splashing and dust overflow, while providing an installation carrier for the crushing rollers 31 and spray pipes, forming a crushing space. The two parallel crushing rollers 31 rotate relative to each other with the help of a crushing motor, and the crushing teeth 32 bite and squeeze the material to achieve physical crushing. The crushed material falls from the bottom of the crushing box 30 into the conveying structure below. Optionally, a screw conveyor can be used as the conveying structure.

[0024] Because the explosives inside fireworks may explode due to compression and heat generation during the crushing process, spray pipes in the corresponding crushing structure cavity spray water onto the crushing rollers 31 through nozzles during each stage of crushing. This wets the explosives and reduces the temperature inside the crushing box 30, thereby lowering the risk of explosion. The spraying action is synchronized with the crushing action, covering the entire crushing process.

[0025] The fireworks and firecrackers destruction device provided by this utility model, compared with the prior art, has multiple crushing structures connected in series through a conveying structure. The crushed particle size gradually decreases from upstream to downstream, achieving the purpose of graded crushing. This avoids the risk of explosion due to incomplete crushing in a single operation, improves overall processing efficiency, and meets the requirements of uninterrupted operation. Each crushing box 30 is equipped with a spray pipe, which can spray water synchronously to cool and passivate the powder and fuse in real time, preventing the combustion or explosion of components such as gunpowder and fuses caused by frictional heat during crushing, eliminating the risk of secondary explosions, and also suppressing the diffusion of dust generated during crushing, thus preventing dust pollution of the air. At the same time, the spraying system can adsorb harmful components that may be released during the crushing process, reducing air pollution. This application features fully mechanized crushing, eliminating the need for direct human contact with flammable and explosive components, and significantly reducing the safety risks of manual operation.

[0026] Optionally, a feeding system is also provided on one side of the destruction device. The feeding system includes a conveyor belt with multiple partitions evenly spaced on the surface of the conveyor belt. The partitions divide the surface of the conveyor belt into multiple storage frames. Each storage frame can hold a certain amount of fireworks and firecrackers, which can prevent excessive accumulation of fireworks and firecrackers on the conveyor belt and cause an explosion.

[0027] The output end of the conveyor belt extends to the feed inlet of the upstream crushing box 30. The material in each storage frame enters the crushing box 30 in an orderly manner, achieving continuous crushing.

[0028] Optionally, the feeding system also includes a soaking tank located on the feeding side of the conveyor belt. For materials with an explosion risk, they need to be soaked in the soaking tank before being placed on the conveyor belt to reduce the chance of an explosion.

[0029] The crushing box 30 and the conveying structure are made of 5mm-6mm thick steel plates or nylon plates are superimposed on the steel plates to form a double-layer plate.

[0030] In some possible embodiments, please refer to Figure 5 The crushing structure also includes fixed biting teeth 33, which are located on the two side walls of the crushing box 30 and mesh with the crushing teeth 32 on the crushing roller 31.

[0031] The fixed biting teeth 33 are located on both sides of the crushing box 30, and they bite with the crushing teeth 32 of the adjacent crushing roller 31 to seal the gap between the inner wall of the crushing box 30 and the crushing roller 31, so as to prevent the material from falling out of the gap.

[0032] After discarded fireworks and firecrackers are fed into the crushing box 30 through the feed inlet, they fall above the rotating crushing rollers 31 under the action of gravity and initially contact the crushing teeth 32. The engagement state of the fixed biting teeth 33 and the crushing teeth 32 directly seals the gap between the inner wall of the crushing box 30 and the crushing rollers 31, preventing the material from falling out of the gap and confining it to the biting area of ​​the crushing rollers 31.

[0033] Without the fixed biting teeth 33, some material may fall through the gap between the crushing roller 31 and the box wall during the crushing process. After the fixed biting teeth 33 close the gap, all material can be forcibly crushed and discharged.

[0034] Optionally, the bottom of the crushing box 30 is open, and the open bottom of the crushing box 30 forms a discharge port.

[0035] In some possible embodiments, please refer to Figures 4 to 5 The conveying structure includes a conveying base plate 41 and a conveying roller 40. The conveying base plate 41 is located below the discharge port of the crushing box 30 and extends along the length direction to above the feed port of another crushing box 30. The conveying base plate 41 is an arc-shaped plate with an upward opening. The conveying roller 40 is located in the arc-shaped inner cavity of the conveying base plate 41. The axial direction of the conveying roller 40 is consistent with the length direction of the conveying base plate 41, and the outer side of the conveying roller 40 is provided with helical blades.

[0036] The conveying structure adopts a screw conveyor. To receive the falling material, the outer shell 10 of the screw conveyor is made of an upward-opening arc-shaped plate, which forms the conveying base plate 41. The first end of the conveying base plate 41 is located below the discharge port of the upstream crushing box 30 and completely covers the discharge port. The second end of the conveying base plate 41 extends above the feed port of the downstream crushing box 30.

[0037] Optionally, since the explosive portion of fireworks still poses a risk of explosion after being broken, a cover plate can be installed on the upper end of the conveyor base plate 41. The first end of the cover plate extends to the crushing box 30, and the second end of the cover plate extends backward to the upper part of the feed inlet of the downstream crushing box 30 and completely covers the feed inlet.

[0038] The second end of the cover plate extends to the outer side of the second end of the conveyor base plate 41 to prevent waste residue from flying out during an explosion. The material of the cover plate is the same as that of the conveyor base plate 41.

[0039] Optionally, the upper edge of the conveying base plate 41 is fixedly connected to the crushing box 30. The conveying base plate 41 is an arc-shaped plate with an upward opening. The upper edge of the conveying base plate 41 extends to the lower end of the crushing box 30 and is fixedly connected to the crushing box 30, thus confining the material discharged from the discharge port between the conveying base plate 41 and the crushing box 30.

[0040] When the explosive is crushed and falls onto the conveyor base plate 41, it may explode again due to factors such as collision and temperature. During the explosion, the material and the blasted waste residue are limited by the conveyor base plate 41 and the crushing box 30 to prevent the waste residue from jumping out.

[0041] Optionally, the conveyor base plate 41 and the crushing box 30 are fixedly connected by bolts, which can improve the installation stability of the conveyor base plate 41 while enclosing the space.

[0042] The conveying base plate 41 and the conveying roller 40 are arranged in parallel. The conveying roller 40 rotates, causing the spiral blades to push the material on the conveying base plate 41 to move downstream.

[0043] To improve material conveying efficiency and prevent material accumulation, the conveyor base plate 41 can be set to a downward tilted state. The tilt angle is less than 15°.

[0044] In some possible embodiments, the fireworks and firecrackers destruction device also includes a base and a support frame 11; the base is used to support the ground; the support frame 11 is disposed on the base, and the crushing system and conveying structure are both installed on the support frame 11; the downstream crushing box 30 forms a discharge space between the base and the ground.

[0045] The base rests directly on the ground, providing a stable foundation for the entire device. A support frame 11 is mounted on the base. The support frame 11 includes vertical and horizontal support rods, which are intersected and fixed together to form a complete frame. The aforementioned crushing system and conveying structure are all fixed to the support frame 11 by bolts or welding. Furthermore, the crushing motor is also mounted on the support frame 11.

[0046] The support frame 11 provides a unified installation benchmark for the crushing and conveying structures, making it easy for each structure to be assembled according to the design precision, ensuring precise docking between the upstream discharge port and the conveying structure, and precise docking between the conveying structure and the downstream feed port, reducing material blockage and spillage problems caused by installation deviations.

[0047] Because the downstream crushing box 30 forms a discharge space between its base and the ground, after the material has been crushed through all the crushing structures, it is finally discharged from the outlet of the downstream crushing box 30. The material can fall directly through this discharge space (or be received by subsequent equipment), completing the material output of the entire crushing process. This discharge space prevents the final crushed material from accumulating directly at the bottom of the device or in the gap between the ground and the equipment, ensuring that the material can be smoothly discharged to subsequent processing stages, reducing the frequency of manual cleaning of accumulated material, and improving the continuity of the overall processing flow. The existence of the discharge space also reserves installation space for possible subsequent collection equipment (such as conveyor belts), enhancing the compatibility of the device with other processing equipment.

[0048] Optionally, the base includes a lateral extension structure and a longitudinal extension structure; the lateral extension structure is connected to the bottom of the support frame 11, and the lateral extension structure includes a lateral fixed part and a lateral movable part that is extended and retracted in the horizontal direction; the longitudinal extension structure includes a support leg connected to the lateral movable part, the support leg is used to support the ground, and the support leg has the freedom to extend and retract in the longitudinal direction.

[0049] The lateral extension structure can adopt a telescopic rod structure, which includes a lateral fixed part and a lateral movable part. The lateral fixed part is a sleeve, and the lateral movable part is a rod-shaped structure that inserts into the sleeve. The lateral fixed part is connected to the bottom of the support frame 11, and the lateral movable part is telescopically adjustable along the length of the lateral fixed part. The two can be fixed by means of set screws, bolts, or other structures. When lateral adjustment of the support legs is required, it can be achieved by telescopically adjusting the lateral movable part.

[0050] Correspondingly, the longitudinally extendable legs can meet the longitudinal adjustment requirements of the material discharge space. Both the telescopic rod structure and the legs can be driven by pneumatic or hydraulic cylinders.

[0051] When the ground is uneven, the extension and retraction of different support legs can be adjusted individually to keep the base and the crushing system and conveying structure above it in a horizontal state.

[0052] Furthermore, this application also includes a housing 10, which is installed around the support frame 11 to protect the internal crushing motor and other structures. The housing 10, support frame 11, and base cooperate to form the entire destruction box. The destruction box proposed in this application can be transported as a whole by means of a truck or other means. The cooperation of the lateral extension structure and the longitudinal extension structure allows the truck bed to smoothly enter the discharge space, and after the truck stops, the base can be placed on the truck bed by adjusting the lateral extension structure and the longitudinal extension structure again. After the truck is transported to the designated location, the base can also be separated from the truck bed by adjusting the lateral extension structure and the longitudinal extension structure, allowing the truck to drive out smoothly.

[0053] The outer casing 10 is provided with multiple openable door structures for easy maintenance. The outer casing 10 is also provided with ventilation holes.

[0054] The upper end of the outer casing 10 is provided with a feed pipe 20, which is surrounded by four side plates. The four side plates are rotatably connected to the outer casing 10 by hinges. The side plates can be flipped to cover the opening of the feed pipe 20.

[0055] Optionally, a longitudinal feed pipe 34 is provided at the feed inlet of the crushing box 30, and the feed pipe 34 is connected to the inner cavity of the crushing box 30. The feed pipe 20 is connected to the upper end of the feed pipe 34 of the upstream crushing box 30.

[0056] In some possible embodiments, the fireworks and firecrackers destruction device also includes a discharge system, which includes a filter press and a discharge mechanism. The inlet end of the discharge mechanism is located in the discharge space, and the discharge mechanism extends upward at an angle to the inlet of the filter press.

[0057] After being crushed in multiple stages, the material is mixed with sprayed water to form a mud-like paste. The mud-like paste is discharged from the discharge port of the downstream crushing box 30 to the discharge mechanism in the discharge space, and then conveyed to the filter press by the discharge mechanism.

[0058] The filter press compresses the muddy material into a dry cake shape. Finally, the material, after being squeezed dry, is piled up for further harmless treatment.

[0059] Optionally, the pressure of the filter press can be adjusted, for example, by installing an adjustable bolt at the spring gland of the filter press. The pressure value of the spring gland can be changed by rotating the adjustable bolt. Filter presses using spring glands are existing technology and will not be described in detail here.

[0060] A screw conveyor can be used as the discharge mechanism to transport materials to the filter press.

[0061] The screw conveyor is inclined upwards and is used for the initial dewatering of muddy materials. The muddy material contains a large amount of water. As the material is moved backward by the blades of the screw conveyor, the water separates from the material and flows downwards until it is discharged from the drain outlet at the lower end of the screw conveyor inlet.

[0062] Optionally, the spraying system also includes a return water pipe, which is connected below the inlet end of the discharge mechanism; the return water pipe is connected to a water source. That is, the water discharged from the drain outlet of the discharge mechanism directly enters the return water pipe for recycling, undergoes harmless treatment, forms greywater, and is then transported to the water source, mixed with the water in the water source, and then transported back to the spraying pipe.

[0063] Optionally, an explosion-proof camera is installed in each crushing chamber 30 to facilitate observation of the working status inside the crushing chamber 30.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
