Description

Technical Field

[0001] This utility model relates to the field of firecracker gunpowder technology, and in particular to a firecracker gunpowder filling safety explosion-proof isolation chamber. Background Technology

[0002] Gunpowder is the core component of traditional fireworks and firecrackers, primarily used to create various pyrotechnic effects. It mainly consists of three basic components: potassium nitrate (oxidizer), sulfur (combustion accelerant), and charcoal (reducing agent), typically in a ratio of 75% potassium nitrate, 10% sulfur, and 15% charcoal. When ignited, this mixture undergoes a rapid oxidation-reduction reaction, releasing a large amount of heat and gases, producing an explosive effect.

[0003] Existing gunpowder storage devices or storage areas lack effective explosion-proof isolation measures in their design. Once explosive gunpowder in a certain area is detonated due to accidental factors (such as static electricity, friction, high temperature or misoperation), the resulting flames and shock waves will spread rapidly to the surrounding space and cannot be effectively contained. This chain reaction will not only ignite nearby stored gunpowder or other flammable materials, but also cause serious damage to surrounding personnel, equipment and building structures.

[0004] Therefore, it is necessary to design a safe and explosion-proof isolation chamber for filling firecracker gunpowder to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, this utility model provides a safe and explosion-proof isolation chamber for filling firecracker gunpowder.

[0006] The technical implementation scheme of this utility model is as follows: a safe and explosion-proof isolation chamber for filling firecracker gunpowder, comprising a support frame, an isolation chamber body, a control panel, a temperature sensor, a feeding hopper, columns, a hopper, a spring, a telescopic tube, a discharge pipe, a discharge valve, a mounting frame, and a cooling pipe. The isolation chamber body is fixedly connected to the upper part of the support frame, the control panel is fixedly connected to the front of the isolation chamber body, and the temperature sensor is fixedly connected to the top of the isolation chamber body. The temperature sensor is electrically connected to the control panel. The feeding hopper is connected and communicated with the upper part of the isolation chamber body. Columns are fixedly connected to both sides inside the isolation chamber body, and a sliding joint is formed between the two columns. The device is equipped with a hopper that divides the isolation chamber into a storage cavity and a buffer cavity. Springs are symmetrically connected between the hopper and the isolation chamber, with two springs wound around corresponding columns. Both springs are located in the buffer cavity area. A telescopic pipe is connected to and communicates with the bottom of the hopper, and a discharge pipe is connected to and communicates with the bottom of the telescopic pipe. The discharge pipe is fixedly sleeved at the bottom of the isolation chamber and connected to and communicates with a discharge valve. Mounting brackets are fixedly connected to both sides of the buffer cavity area. Multiple refrigeration pipes are fixedly connected axially between the two mounting brackets, and all of the multiple refrigeration pipes are electrically connected to the control panel.

[0007] As an improvement to the above scheme, the hopper structure is hemispherical.

[0008] As an improvement to the above solution, it also includes a material distribution plate, a motor, a rotating shaft, a protective frame, a gear, a gear ring, and a scraper. The material distribution plate is fixedly connected to the upper part of the isolation chamber. Multiple sets of through holes are opened in a circular array on the material distribution plate. The motor is fixedly connected to the top of the isolation chamber. The motor is electrically connected to the control panel. The output shaft of the motor passes through the isolation chamber and is fixedly connected to the rotating shaft. The protective frame is fixedly connected between the upper parts of the two columns. The gear is fixedly connected to the bottom of the rotating shaft. The gear ring is rotatably connected inside the protective frame. The gear meshes with the gear ring. The scraper is fixedly connected to the top of the gear ring.

[0009] As an improvement to the above solution, the scraper frame is provided with a ring array of multiple scrapers, all of which abut against the top surface of the distribution plate.

[0010] As an improvement to the above solution, the motor is located behind the temperature sensor.

[0011] As an improvement to the above solution, it also includes gas tanks, a three-way pipe, a solenoid valve, a connecting pipe, and a nozzle. Gas tanks are symmetrically fixed to the top of the isolation chamber. A three-way pipe connects and communicates between the two gas tanks. A solenoid valve is connected and communicates to the bottom of the three-way pipe. The solenoid valve is electrically connected to the control panel. A connecting pipe is connected and communicates to the bottom of the solenoid valve. The connecting pipe passes through the top of the isolation chamber and is connected and communicates with the nozzle.

[0012] This utility model has the following advantages: 1. This utility model achieves automatic buffering and reset functions during the gunpowder filling process through the sliding cooperation between the hopper and the column and the elastic support of the spring, effectively adapting to the needs of different filling volumes, improving the adaptability and stability of the equipment. Through the linkage control of the temperature sensor and the cooling pipe, the internal temperature of the isolation chamber is monitored and adjusted in real time to prevent the gunpowder from spontaneously combusting or exploding due to high temperature, significantly improving safety. At the same time, the cooperation between the telescopic pipe and the discharge pipe ensures smooth discharge, avoids blockage, ensures production continuity, improves the safety and efficiency of firecracker gunpowder filling, and also enhances the reliability and ease of operation of the equipment.

[0013] 2. This utility model uses a motor-driven rotating shaft to drive a gear and a gear ring to mesh and transmit power, thereby realizing the rotational movement of the scraper above the distribution plate. This allows the scraper to evenly scrape the gunpowder falling onto the distribution plate axially, distributing it radially and allowing it to slide smoothly into the through hole. This effectively prevents problems such as gunpowder accumulation, blockage, or uneven feeding, and realizes the automation, continuity, and uniformity of the gunpowder filling process, significantly improving filling efficiency and stability. At the same time, it avoids the safety hazards caused by manual intervention and enhances the safety and reliability of equipment operation.

[0014] 3. This utility model achieves real-time monitoring and intelligent feedback of the temperature inside the isolation chamber through the electrical connection between the temperature sensor and the control panel. Once an abnormal temperature is detected, the solenoid valve is immediately triggered to open, so that the high-pressure fire extinguishing gas in the gas tank is delivered to the nozzle through the three-way pipe and connecting pipe, and is quickly and evenly sprayed into the chamber, effectively cooling down and suppressing the spread of fire, achieving the purpose of rapid fire extinguishing and explosion prevention, and can intervene in time at the beginning of a fire.

Detailed Implementation

[0022] Example: A safety explosion-proof isolation chamber for filling firecracker gunpowder, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the device includes a support frame 1, an isolation chamber 2, a control panel 3, a temperature sensor 4, a feed hopper 5, columns 6, a hopper 7, a spring 8, a telescopic tube 9, a discharge pipe 10, a discharge valve 1001, a mounting bracket 11, and a cooling pipe 12. The isolation chamber 2 is screwed onto the upper part of the support frame 1. The control panel 3 is screwed onto the center of the front side of the isolation chamber 2. The temperature sensor 4 is screwed onto the top front side of the isolation chamber 2 and is electrically connected to the control panel 3. The feed hopper 5 is connected and communicates with the upper left side of the isolation chamber 2. Columns 6 are welded to both the left and right sides inside the isolation chamber 2. A hopper 7 is slidably connected between the two columns 6. The hopper 7 has a hemispherical structure, which helps to distribute the material more evenly. Inside the hopper 7, to reduce material accumulation or segregation, the hopper 7 divides the isolation chamber 2 into a storage cavity and a buffer cavity. Springs 8 are symmetrically connected between the hopper 7 and the isolation chamber 2. Both springs 8 are wound around the corresponding columns 6 and are located in the buffer cavity area. The bottom of the hopper 7 is connected to and connected to a telescopic pipe 9. The bottom end of the telescopic pipe 9 is connected to and connected to a discharge pipe 10. The discharge pipe 10 is fixedly sleeved at the bottom of the isolation chamber 2. The bottom of the discharge pipe 10 is connected to and connected to a discharge valve 1001. Mounting brackets 11 are installed on both the upper and lower sides of the buffer cavity area by screws. Multiple cooling pipes 12 are installed axially between the two mounting brackets 11 by screws. The multiple cooling pipes 12 are electrically connected to the control panel 3.

[0023] When this device is needed, the external feed pipe feeds gunpowder into the isolation chamber 2 through the feed bin 5. The gunpowder falls from the feed bin 5 into the hopper 7 below. As gunpowder is continuously added, and as the weight of the gunpowder in the hopper 7 increases, the hopper 7 moves downward along the two side columns 6. The columns 6 not only provide support but also allow the hopper 7 to slide on them. The downward movement of the hopper 7 compresses the telescopic tube 9 connected to its bottom, and at the same time, the spring 8 is also compressed and deformed. The spring 8 acts as a buffer and reset mechanism. The temperature sensor 4 monitors the temperature changes inside the isolation chamber 2 in real time. If the temperature sensor 4 detects that the internal temperature is too high, it will transmit a signal to the control panel 3. The control panel 3... The cooling pipe 12 is activated according to the preset safety threshold to reduce the temperature inside the isolation chamber 2 and prevent the risk of explosion caused by high temperature. When it is necessary to discharge gunpowder, the unloading valve 1001 can be opened through the control panel 3. The gunpowder in the hopper 7 first flows into the discharge pipe 10 below through the telescopic pipe 9 at the bottom, and finally is discharged from the isolation chamber 2 through the discharge pipe 10. When the gunpowder in the hopper 7 is completely discharged, the weight of the hopper 7 is reduced. At this time, the previously compressed spring 8 begins to release elastic potential energy, pushing the hopper 7 to move upward along the column 6 and return to the initial position. During this process, the telescopic pipe 9 will also naturally extend as the hopper 7 rises, ready to receive the next gunpowder filling.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, it also includes a material distribution plate 13, a motor 14, a rotating shaft 15, a protective frame 16, a gear 17, a gear ring 18, and a scraper 19. The material distribution plate 13 is welded to the upper part of the isolation chamber 2. The material distribution plate 13 has multiple sets of through holes arranged in a ring array. The motor 14 is installed on the front top of the isolation chamber 2 by screws. The motor 14 is electrically connected to the control panel 3. The motor 14 is located directly behind the temperature sensor 4. The output shaft of the motor 14 passes through the isolation chamber 2 and extends downward to the rotating shaft 15. The protective frame 16 is welded between the upper parts of the two columns 6. The gear 17 is welded to the bottom end of the rotating shaft 15. The gear ring 18 is rotatably connected inside the protective frame 16. The gear 17 meshes with the gear ring 18. The scraper 19 is welded to the top of the gear ring 18. The scraper 19 has multiple scrapers arranged in a ring array on the scraper 19. All the scrapers abut against the top surface of the material distribution plate 13.

[0025] After the gunpowder flows from the feed hopper 5 into the isolation chamber 2, it first falls onto the surface of the distribution plate 13 located at the top of the chamber. During the continuous flow of gunpowder, to prevent gunpowder accumulation and blockage or uneven distribution, the operator can start the motor 14 through the control panel 3. The output shaft of the motor 14 drives the rotating shaft 15 to rotate downwards. The rotating shaft 15 drives the gear 17. As the gear 17 rotates, it drives the gear ring 18 to rotate synchronously, and the scraper 19 also rotates. During the rotation, the scraper scrapes the gunpowder that falls on the distribution plate 13 evenly along the axial direction, making it radially distributed, and gradually slides into the various through holes on the distribution plate 13, and finally falls into the hopper 7 below. This effectively solves the problems of local accumulation, poor flowability, and poor discharge that may occur during the filling process of gunpowder, ensuring the continuity, stability and safety of the gunpowder filling process. When all the gunpowder has been conveyed, the motor 14 stops working and the scraper 19 stops rotating. If the next round of filling is required, the above process can be repeated by simply starting the motor 14 again.

[0026] like Figure 1 and Figure 6 As shown, it also includes a gas tank 20, a three-way pipe 21, a solenoid valve 22, a connecting pipe 23, and a nozzle 24. The gas tanks 20 are symmetrically installed on the top of the isolation chamber 2 by screws. The two gas tanks 20 are connected and communicated by a three-way pipe 21. The bottom of the three-way pipe 21 is connected and communicated with a solenoid valve 22. The solenoid valve 22 is electrically connected to the control panel 3. The bottom of the solenoid valve 22 is connected and communicated with a connecting pipe 23. The connecting pipe 23 passes into the isolation chamber 2 and is connected and communicated with the nozzle 24 at the top.

[0027] Temperature sensor 4 monitors the temperature changes inside the chamber in real time and feeds the data back to the control panel 3, which is electrically connected to it. Once temperature sensor 4 detects that the temperature inside the chamber exceeds the preset safety threshold, the control panel 3 activates the solenoid valve 22. After the solenoid valve 22 opens, the high-pressure extinguishing gas in the gas cylinder 20 is allowed to enter the three-way pipe 21 and converge with the solenoid valve 22. The high-pressure gas from the solenoid valve 22 enters the isolation chamber 2 through the connecting pipe 23 and finally reaches the nozzle 24. The high-pressure extinguishing gas is quickly sprayed through the nozzle 24 to various parts of the chamber, rapidly reducing the local temperature, inhibiting the spread of flames, and diluting the oxygen concentration to achieve the effect of suffocation extinguishing. Since the entire system is centrally managed by the control panel 3, the entire process from the temperature sensor 4 detecting the abnormal temperature to the completion of the extinguishing gas spray can be completed in a very short time, minimizing the damage caused by fire or explosion. After the fire is extinguished, the control panel 3 closes the solenoid valve 22 and checks whether the pressure of the gas cylinder 20 is sufficient, replenishing it if necessary.
