Description

Technical Field

[0001] This utility model relates to the field of fireworks drying room technology, specifically a directional circulating fireworks drying room. Background Technology

[0002] Fireworks and firecrackers are arts and crafts made from gunpowder. They are traditional entertainment products that produce sound, light, color, and smoke effects through combustion or explosion. Bright beads, as the core component of fireworks and firecrackers, are made by mixing potassium nitrate, sulfur, charcoal powder, and other chemical raw materials in a specific ratio. They are small spherical in shape and mainly determine the color presentation when the fireworks are set off. During the production and manufacturing process of fireworks and firecrackers, bright beads need to go through a drying process to ensure that the moisture is removed evenly, so as to avoid uneven color or explosion caused by residual moisture during combustion.

[0003] When existing fireworks drying chambers are in use, the sulfur contained in the bright beads will generate toxic and harmful gases such as hydrogen sulfide, sulfur dioxide, and sulfur trioxide during contact with high-temperature water vapor. However, most drying chambers lack a mechanism to purify and release these toxic and harmful gases. This means that after the bright beads are dried, a long waiting time is required before they can enter the drying chamber. This not only causes some pollution to the environment near the drying chamber, but also delays the drying efficiency of the bright beads to a certain extent, which is not conducive to the production and manufacturing of fireworks.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7 As shown, a directional circulating fireworks drying chamber includes a base 1, with a drying chamber body 2 fixedly connected to the top of the base 1. A hot air wall 3 is vertically installed inside the drying chamber body 2, dividing the internal space of the drying chamber body 2 into a circulation zone 4 and a drying zone 5. A partition plate 6 is fixed to one side of the hot air wall 3. A heat pump unit 7 is fixedly installed on one side of the circulation zone 4. A processing box 23 is fixedly connected to the top of one side of the drying chamber body 2. The processing box 23 has a processing chamber 24 inside. It should be noted that the heat pump unit 7 is specifically a YBJ-YY-SHXNY-1 heat pump drying and dehumidifying unit, which mainly relies on absorbing the heat energy of the ambient air or absorbing the waste heat of the exhaust during the drying process to transfer the energy to the drying chamber body 2 to achieve the drying of the items. A condenser assembly 28 is set in... The interior of the processing chamber 24 is used for heat exchange of high-temperature toxic and harmful moisture. The top of the drying zone 5 is provided with a vent 27, and a wide mask 26 is fixedly installed on the top of the vent 27. An exhaust pipe 25 is fixedly connected to the top of the wide mask 26. The top of the exhaust pipe 25 is connected to the processing box 23. Moisture mixed with toxic and harmful gases can be introduced into the interior of the processing chamber 24 through the vent 27, the exhaust pipe 25, and the exhaust pipe 25. The residual heat of the toxic and harmful moisture can be recovered and reused by the condensation component 28, thereby reducing the waste of heat energy to a certain extent. At the same time, after the toxic and harmful moisture loses heat and condenses into a liquid state, some of the toxic and harmful substances will dissolve into the condensate, which helps to reduce the harm and impact caused by the direct emission of toxic and harmful gases.

[0016] One side of the hot air wall 3 has an air outlet sluice 10, and a second grille plate 11 is fixedly installed inside the air outlet sluice 10. The other side of the hot air wall 3 has an air inlet sluice 8, and a first grille plate 9 is fixedly installed inside the air inlet sluice 8. A support plate 12 is provided on one side of the first grille plate 9. The support plate 12 is connected to both the hot air wall 3 and the drying chamber body 2. Multiple positioning slots 13 are symmetrically arranged inside the support plate 12, and a first fan 14 is installed inside each positioning slot 13. Figure 2 , Figure 3 and Figure 4As shown, after the heat pump unit 7 absorbs the heat energy from the air in the environment or absorbs the waste heat from the exhaust during the drying process and transfers the energy to the main body of the drying chamber 2, the first fan 14 can drive the hot air through the air inlet slot 8 to the interior of the drying zone 5. Then the hot air dries the bright beads and returns to the interior of the circulation zone 4 through the air inlet slot 8. This cycle is repeated to achieve directional circulation drying of hot air, which is beneficial to improving the drying efficiency and drying effect of the bright beads.

[0017] The drying zone 5 is equipped with a material transport trolley 15. The material transport trolley 15 has multiple symmetrically arranged material trays 16 inside. A spray bend pipe 17 is fixedly installed at the bottom of the inner cavity of the drying zone 5. Spray nozzles 18 are intermittently and evenly spaced on the side of the spray bend pipe 17 facing the material transport trolley 15. Figure 2 , Figure 3 and Figure 4 As shown, in actual use, the bright beads to be dried are placed inside each of the material trays 16. Multiple material trays 16 are stacked in layers inside the material transport trolley 15. The staff pushes the material transport trolley 15 into the drying area 5. The spray bend 17 and spray head 18 can prevent the four corner wheels of the material transport trolley 15 from rubbing against the ground of the drying chamber 2 or from sparks or static electricity caused by people dropping things. It should be noted that when loading, the bright beads must be lower than the height of the tray 16. At the same time, a cloth is covered on the top of the material tray 16 to ensure that the hot air will not blow over the material during directional circulation. The first grid plate 9, the second grid plate 11 and the material trays 16 of each layer of the material transport trolley 15 are horizontally aligned. The hot air circulates accurately and horizontally without obstruction at the upper port of each layer of material tray 16.

[0018] The condensation assembly 28 includes a condensation bend 281 fixed inside the processing chamber 24. Multiple liquid guide holes 282 are symmetrically arranged at the bottom of the condensation bend 281. A spiral water channel 284 is provided on the outer side of the condensation bend 281. One end of the spiral water channel 284 is connected to a straight outlet pipe 285. A first U-shaped pipe 287 is provided on the outer side of one end of the processing tank 23. One end of the straight outlet pipe 285 passes through the processing tank 23 and connects to the first U-shaped pipe 287. A drain port 2810 is provided at the bottom of the first U-shaped pipe 287. The spiral water channel 281... The other end of 84 is connected to a straight inlet pipe 286. A second U-shaped pipe 288 is provided on the outer side of the other end of the treatment tank 23. One end of the straight inlet pipe 286 passes through the treatment tank 23 and connects to the second U-shaped pipe 288. A liquid pump 289 is located below the second U-shaped pipe 288. The liquid pump 289 is fixedly installed on the top of the treatment tank 23. The outlet of the liquid pump 289 is connected to the second U-shaped pipe 288 through a pipe. A liquid guide groove 283 is provided at the bottom of the treatment chamber 24. A solenoid valve is installed inside one end of the liquid guide groove 283. Figure 5 , Figure 6 and Figure 7As shown, the liquid pump 289 can sequentially introduce water with a lower external temperature into the spiral water channel 284 through the second U-shaped pipe 288 and the inlet straight pipe 286. The spiral water channel 284 can prolong the residence time of the low-temperature water inside the condenser bend 281. Then, the moisture mixed with toxic and harmful gases will enter the interior of the condenser bend 281 through the exhaust port 27, the exhaust bend 25, and the exhaust bend 25. When the high-temperature toxic and harmful gas moisture comes into contact with the inner wall of the cooling section of the condenser bend 281, it will rapidly release heat and condense into droplets. Due to gravity, the water flows downward through the liquid guide hole 282 into the liquid guide tank 283. The water that has absorbed heat then flows sequentially through the liquid outlet straight pipe 285, the first U-shaped pipe 287, and the liquid outlet 2810 into the external recovery pipe. This achieves the recovery and reuse of the residual heat of the toxic and harmful moisture, which reduces the waste of heat energy to a certain extent. At the same time, after the toxic and harmful moisture loses heat and condenses into liquid, some of the toxic and harmful substances will dissolve into the condensate, which helps to reduce the harm and impact caused by the direct emission of toxic and harmful gases.

[0019] The treatment chamber 23 has a purification chamber 33 inside. The top of the purification chamber 33 has at least two through slots 29. A quadrilateral frame 30 is installed inside the through slots 29. An activated carbon filter plate 31 is fixedly connected inside the quadrilateral frame 30. The top of the quadrilateral frame 30 extends to the outside of the treatment chamber 23 and is fixedly connected to a strip-shaped seat 32. An exhaust vent 34 is provided on one side of the inner wall of the purification chamber 33. A second fan 35 is installed inside the exhaust vent 34. Figure 5 , Figure 6 As shown, the second fan 35 inside the exhaust vent 34 can generate a negative pressure environment inside the purification chamber 33, thereby causing the gas that has been preliminarily purified by the condenser component 28 inside the treatment chamber 24 to enter the purification chamber 33. The activated carbon filter plate 31 inside the quadrilateral frame 30 can achieve secondary filtration and purification of toxic and harmful substances. When the activated carbon filter plate 31 needs maintenance and replacement, the staff can use external ladders or other climbing equipment to reach the top of the drying chamber 2 and pull the quadrilateral frame 30 out of the through groove 29, thereby further reducing the harm and impact caused by the direct emission of toxic and harmful gases.

[0020] A first outlet 19 is provided on one side of the inner wall of the drying zone 5. A first door panel 20 is hinged to one side of the first outlet 19. The free end of the first door panel 20 is connected to the other side of the first outlet 19 by a latch. A third outlet 36 is provided on the other side of the inner wall of the drying zone 5. A third door panel 37 is hinged to both sides of the third outlet 36 and is connected to the third door panel 37 by a latch. A second outlet 21 is provided on one side of the inner wall of the circulation zone 4. A second door panel 22 is hinged to one side of the second outlet 21. The free end of the second door panel 22 is connected to the other side of the second outlet 21 by a latch. Figure 1 , Figure 4 and Figure 5As shown, in actual use, the third outlet 36 serves as the main material inlet and outlet. By setting the first outlet 19 and the second outlet 21, it is convenient for staff to enter the interior of the circulation zone 4 and the drying zone 5, thereby facilitating the maintenance of components or loading and unloading of materials. It should be noted that this utility model does not make any changes to the electronic device circuits and designs mentioned in the text. At the same time, all electronic devices mentioned in this utility model are connected to the PLC controller terminals via data cables. The PLC controller centrally manages the electronic devices of this utility model, facilitating the coordinated management of the operation of each electronic device.

[0021] Working principle: First, the staff pushes the material trolley 15 into the drying zone 5 to dry the bright beads in the material tray 16. Then, the heat pump unit 7 absorbs the heat energy from the ambient air or the waste heat from the exhaust during the drying process and transfers the energy to the main body of the drying chamber 2. The first fan 14 drives the hot air through the air inlet slot 8 to the inside of the drying zone 5. The hot air then dries the bright beads and returns to the circulation zone 4 through the air inlet slot 8. This cycle is repeated to achieve directional circulation drying of hot air, which helps to improve the drying efficiency and effect of the bright beads. During this process, the condenser component 28 can recover and reuse the residual heat of toxic and harmful moisture, which reduces the waste of heat energy to a certain extent. At the same time, after the toxic and harmful moisture loses heat and condenses into liquid, some of the toxic and harmful substances will dissolve into the condensate, which helps to reduce the harm and impact caused by the direct emission of toxic and harmful gases. Furthermore, the activated carbon filter plate 31 can achieve secondary filtration and purification of toxic and harmful substances, which further reduces the harm and impact caused by the direct emission of toxic and harmful gases.
