Description

Technical Field

[0001] The invention relates to the field of fireproof rolling curtains, and in particular to an intelligent hydrometallurgical extraction and separation section fire extinguishing system. Background Art

[0002] Traditional fireproof roller shutters mainly rely on a single physical barrier to block flames and heat radiation. Although they can prevent the spread of fire to a certain extent, the fire resistance of the roller shutters themselves is limited under high temperatures, and it is difficult to maintain effective isolation for a long time. Once the roller shutters are damaged by high temperatures, their fireproof effect will be greatly reduced and they will not be able to provide continuous protection.

[0003] The currently disclosed Chinese patent CN111764802B discloses a fireproof rolling shutter door, including a curtain sheet, a bottom hook, a rib plate, a top hook and a stopper. The curtain sheet is a hollow strip structure, a rib plate is arranged in the middle of the curtain sheet, a top hook is arranged on the upper part of the curtain sheet, a bottom hook is arranged on the lower part of the curtain sheet, asbestos is filled inside the curtain sheet, and stoppers are inserted on both sides of the curtain sheet; a plurality of curtain sheets form a curtain door, and two adjacent curtain sheets are connected by the top hook on the lower curtain sheet hooked on the bottom hook on the upper curtain sheet; the fireproof rolling shutter door also includes a guide sheet and a steel pipe, and the uppermost curtain sheet is connected with a guide sheet by rivets The fireproof rolling shutter door also includes a transverse rib and a tubular motor, and the output shaft of the tubular motor is provided with a transverse rib, and the output shaft and the transverse rib of the tubular motor are both inserted into the right part of the steel pipe; the fireproof rolling shutter door also includes a bearing seat, a side shaft, a connecting block and a side cover plate, one side cover plate is provided on each side, the right end of the tubular motor is fixedly connected to the side cover plate on the right side, the left end of the steel pipe is fixedly connected to the connecting block, the left side of the connecting block is fixedly connected to the side shaft, the left end of the side shaft is rotatably connected to the bearing seat, and the bearing seat is fixedly connected to the side cover plate at the left end.

[0004] According to the above patent, the above patent forms a rolling shutter door by connecting multiple curtain pieces to each other. The curtain pieces are filled with asbestos. Asbestos makes the rolling shutter door fireproof. However, the rolling shutter has no cooling function and can only rely on asbestos to resist high temperature. This single protection method is prone to premature failure of the rolling shutter when facing a fierce fire. In addition, due to the impact of the heat wave, the rolling shutter will also be under great pressure, so it will be damaged and can no longer play an isolation effect. Therefore, there is a need for an intelligent hydrometallurgical extraction and separation section fire extinguishing system that uses cooling and buffering mechanisms to provide more comprehensive fire protection. Summary of the invention

[0005] In view of the problems existing in the existing technology, an intelligent hydrometallurgical extraction and separation section fire extinguishing system is provided.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention continuously monitors the environment through smoke sensors and infrared cameras of patrol robots.

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figure 1-Figure 9 As shown, an intelligent hydrometallurgical extraction and separation section fire extinguishing system includes a fire hazard robot automatic inspection system, a fire hazard and fire automatic disposal system, and a pollutant collection system during the fire disposal process. A fire hazard robot automatic inspection system is used to perform infrared camera temperature measurement inspections on the extraction line area, a fire hazard and fire automatic handling system is used to isolate and extinguish the fire area, and a pollutant collection system during the fire handling process is used to collect water generated by fire extinguishing and leaked materials. Among them, the fire hazard and fire automatic handling system includes a track-type fire-fighting robot and a fireproof roller shutter isolation fire-extinguishing device. The fireproof roller shutter isolation fire-extinguishing device includes a roller shutter mechanism 2 applied around the extraction tank 1 of the hydrometallurgical extraction line, and the roller shutter mechanism 2 includes a frame 21, a first curtain piece 22 and a second curtain piece 23. The upper parts of the first curtain piece 22 and the second curtain piece 23 are fixedly connected to a reel 221 that is rotatable and arranged on the frame 21, and the lower parts of the first curtain piece 22 and the second curtain piece 23 are fixedly connected to a movable roller 222 that can move vertically on the frame 21. The frame 21 is provided with a rotating driver for simultaneously driving the two reels 221 to rotate so that the first curtain piece 22 and the second curtain piece 23 are rolled up or drooped and unfolded.

[0040] The rotary drive is not shown in the figure. The fire hazard robot automatic inspection system has a smoke sensor 11 and an inspection robot infrared camera 12 located above the extraction tank 1. The smoke sensor 11 is fixedly installed in the middle of the fire isolation zone. A track for the inspection robot infrared camera 12 and the track-type fire-fighting robot to walk is set up above the fire isolation zone. The track-type fire-fighting robot is specifically a carbon dioxide fire-fighting robot 13 that can move along the track. The pollutant collection system during the fire disposal process has a fire waste liquid collection tank 14 located below the extraction tank 1.

[0041] The infrared camera 12 of the inspection robot performs a 360° infrared camera temperature inspection on the mixing motor and the top of the extraction tank 1 at regular intervals. When the motor temperature exceeds 60°C, the system will feedback to the operator and maintenance personnel to repair to prevent the motor from heating and causing a fire. When the motor temperature or the temperature of other points on the tank surface exceeds 80°C (the flash point of solvent kerosene), the system will feedback to the operator and maintenance personnel to take emergency measures.

[0042] One or more carbon dioxide fire-fighting robots 13 are deployed on the track. When the infrared camera 12 of the inspection robot senses an early fire, it immediately notifies the operator and the carbon dioxide fire-fighting robot 13. The carbon dioxide fire-fighting robot 13 quickly rushes to the fire area and aims the carbon dioxide nozzle at the flame area according to the smoke and fire recognition system it carries, and releases enough carbon dioxide to extinguish the fire. Four rolling shutter mechanisms 2 are set more than 2 meters above the extraction tank 1 in each partition area to form an isolation area. When the carbon dioxide fire-fighting robot 13 cannot control the fire, it will notify the fire hazard and fire automatic disposal system and the DCS system. The DCS system will automatically start the rolling shutter mechanism 2. The four rolling shutter mechanisms 2 are driven at the same time. Adjacent fire protection areas can share one rolling shutter mechanism 2 (or two can be set, each with its own), ensuring that all rolling shutter mechanisms 2 can fall at the same time.

[0043] Under normal circumstances, the first curtain piece 22 and the second curtain piece 23 of the rolling curtain mechanism 2 are both in a rolled-up state, and the roller 221 is controlled by a rotary driver to roll up the first curtain piece 22 and the second curtain piece 23. The smoke detector 11 and the inspection robot infrared camera 12 continuously monitor the extraction tank 1 and its surrounding environment to ensure that there is no sign of fire.

[0044] When a fire occurs in the extraction tank 1, the smoke sensor 11 and the inspection robot infrared camera 12 will immediately detect the fire signal and transmit the signal to the control system. After receiving the fire signal, the control system starts the emergency procedure, including starting the rotary drive, the water curtain generator 3, the steam ejector 4 and the carbon dioxide fire extinguishing robot 13. The control system starts the rotary drive to drive the two rollers 221 to rotate in the opposite direction, so that the first curtain sheet 22 and the second curtain sheet 23 are simultaneously drooped and unfolded.

[0045] Since the extraction tank 1 is surrounded by rolling shutter mechanisms 2, the fire is isolated therein, preventing the fire from spreading outward. At the same time, the carbon dioxide fire-fighting robot 13 is started, and according to the fire signal and the real-time monitoring of the patrol robot infrared camera 12, it automatically locates the fire source and sprays carbon dioxide to extinguish the fire. Carbon dioxide can quickly reduce the oxygen concentration at the fire source, extinguish the flames, and prevent the fire from spreading further. During the fire-fighting process, the waste liquid generated will be collected in the fire-fighting waste liquid collection tank 14 under the extraction tank 1 to prevent secondary pollution. After the above series of measures, the fire was effectively controlled and eventually extinguished. After the fire was extinguished, the rotary drive was started again to re-roll up the first curtain piece 22 and the second curtain piece 23, restoring them to the initial state, ready to deal with the next emergency.

[0046] See also Figure 6-Figure 9As shown, a sliding portion 2221 slidably arranged on a frame 21 is fixedly provided between the ends of the two movable rollers 222, and a sliding groove for the sliding portion 2221 to slide is provided on the frame 21. A water curtain generator 3 for forming a layer of water film on the surface of the first curtain sheet 22 and a steam ejector 4 for extinguishing fire are provided on the side of the first curtain sheet 22 facing the extraction tank 1. When the first curtain sheet 22 and the second curtain sheet 23 are both in an unfolded state, a cooling space 24 is formed between the first curtain sheet 22 and the second curtain sheet 23, and a cooling pipe 241 for passing cooling gas into the cooling space 24 is provided on the frame 21.

[0047] As the roller 221 rotates, the first curtain sheet 22 and the second curtain sheet 23 are gradually unfolded. Under the gravity of the movable roller 222, the sliding part 2221 slides in the sliding groove to ensure that the first curtain sheet 22 and the second curtain sheet 23 are smoothly unfolded.

[0048] When the first curtain sheet 22 and the second curtain sheet 23 are fully unfolded, a cooling space 24 is formed between the first curtain sheet 22 and the second curtain sheet 23. The cooling pipe 241 is activated to pass the cooling gas into the cooling space 24. The cooling gas flows in the cooling space 24, further reducing the temperature of the first curtain sheet 22 and its surroundings, providing an additional cooling effect, effectively blocking the transfer of flames and heat radiation, and preventing the spread of fire.

[0049] The water curtain generator 3 is started at the same time, and starts to spray water curtain on the surface of the first curtain sheet 22 to form a layer of water film. The water curtain can quickly absorb heat, reduce the temperature of the first curtain sheet 22 and its surrounding environment, and slow down the heat conduction speed. The water curtain can also block the transfer of part of the flame and heat radiation, protecting the first curtain sheet 22 from direct flame impact.

[0050] The steam injector 4 is also started at the same time to start injecting steam to dilute the oxygen in the air, inhibit the combustion process, and help control the spread of fire.

[0051] See also Figure 6-Figure 10 As shown, the movable roller 222 of the first curtain sheet 22 is composed of a shaft portion 2222 and a sleeve portion 2223, the shaft portion 2222 is fixedly connected to the sliding portion 2221, the sleeve portion 2223 is rotatably sleeved on the shaft portion 2222, the lower portion of the first curtain sheet 22 is fixedly connected to the sleeve portion 2223, and a torsion spring 223 is fixedly connected between the sleeve portion 2223 and the shaft portion 2222 for buffering the first curtain sheet 22 when it is impacted by a heat wave. When the first curtain sheet 22 is impacted by a heat wave, the torsion spring 223 is in a torsion state, so that the pressure on the first curtain sheet 22 is buffered.

[0052] A positioning structure capable of fixing the movable roller 222 is provided at the bottom of the frame 21 so that the unfolding of the first curtain sheet 22 and the second curtain sheet 23 remains stable. The positioning structure is not shown in the figure.

[0053] When the first curtain sheet 22 and the second curtain sheet 23 are unfolded simultaneously, the movable roller 222 of the first curtain sheet 22 is directly fixed by the positioning structure, while the movable roller 222 of the second curtain sheet 23 fixes the shaft portion 2222 through the positioning structure, and the sleeve portion 2223 is still in a state of being able to rotate relative to the shaft portion 2222.

[0054] When the first curtain piece 22 is impacted by a heat wave, since the sleeve portion 2223 is rotatably sleeved on the shaft portion 2222 and with the action of the torsion spring 223, the sleeve portion 2223 can rotate a certain angle relative to the shaft portion 2222, and the torsion spring 223 is in a torsion state, which helps the first curtain piece 22 to buffer the impact force and reduce excessive deformation or damage caused by the heat wave impact.

[0055] See also Figure 6-Figure 9 As shown, a pressure buffer component 5 is provided on the frame 21 and is located between the first curtain sheet 22 and the second curtain sheet 23 to enhance the buffering effect of the first curtain sheet 22 .

[0056] When the first curtain sheet 22 is impacted by the heat wave, the pressure buffer assembly 5 further absorbs the impact energy. The pressure buffer assembly 5 cooperates with the torsion spring 223 in the sleeve portion 2223 to jointly reduce the impact force of the heat wave on the first curtain sheet 22.

[0057] The buffering effect of the first curtain piece 22 when subjected to the impact of heat waves is significantly enhanced, so that the first curtain piece 22 has higher stability after being deployed, and the efficient isolation performance of the first curtain piece 22 can be maintained even in the case of a large fire.

[0058] See also Figure 6-Figure 12 As shown, the pressure buffer assembly 5 includes a support rod 51 movably arranged between the first curtain sheet 22 and the second curtain sheet 23 and a plurality of elastic buffer members 52 evenly distributed on the support rod 51. When the first curtain sheet 22 and the second curtain sheet 23 are unfolded or rolled up, the support rod 51 is in a state of synchronous and unidirectional movement with the movable roller 222, so that the support rod 51 is always between the first curtain sheet 22 and the second curtain sheet 23.

[0059] When the first curtain piece 22 and the second curtain piece 23 are gradually unfolded, the support frame rod 51 is also unfolded at the same time.

[0060] When the first curtain sheet 22 is impacted by a heat wave, the sleeve portion 2223 can rotate relative to the shaft portion 2222, and the torsion spring 223 is in a torsion state, which plays a preliminary buffering effect. At the same time, the elastic buffer member 52 on the support frame rod 51 starts to play a role.

[0061] The elastic buffers 52 are evenly distributed on the support rod 51, ensuring that the entire support rod 51 can evenly absorb and disperse the impact force. When the first curtain sheet 22 is impacted by a heat wave, the elastic buffers 52 will be compressed to further absorb the impact energy.

[0062] See also Figure 6-Figure 11 As shown, both ends of the cooling pipe 241 extend toward a sliding portion 2221 respectively and the cooling pipe 241 is fixedly connected to the sliding portion 2221, the axial direction of the cooling pipe 241 is parallel to the axial direction of the movable roller 222, and a plurality of air holes 2411 are opened on the top of the cooling pipe 241 along its axial direction. When the movable roller 222 moves to the bottom of the frame 21, the cooling pipe 241 is at the bottom of the frame 21 at the same time. At this time, the cooling gas ejected from the air holes 2411 is in a spraying state that permeates the cooling space 24 formed from bottom to top.

[0063] When the movable roller 222 moves to the bottom of the frame 21, the cooling pipe 241 also moves to the bottom of the frame 21. At this time, the air holes 2411 on the cooling pipe 241 begin to spray cooling gas. The cooling gas is sprayed from the air holes 2411 from bottom to top and diffuses in the cooling space 24 formed.

[0064] The bottom-up spraying method helps to quickly reduce the temperature around the first curtain sheet 22, prevent the high temperature from damaging the first curtain sheet 22, and evenly cover the entire cooling space 24 to ensure a more uniform temperature distribution. By continuously spraying cooling gas, the spread of fire can be effectively suppressed and the overall fire prevention performance can be improved.

[0065] See also Figure 6-Figure 12 As shown, one end of the support frame rod 51 is movably connected to the frame 21, and the other end is movably connected to the cooling pipe 241. The upper half of the frame 21 has a hinge seat 511 for hinged connection of the end of the support frame rod 51. The sliding sleeve on the cooling pipe 241 is provided with a sliding sleeve 512, and the sliding sleeve 512 has a hinge portion 5121 for hinged connection of the end of the support frame rod 51. When the movable roller 222 moves along the slide groove, with the sliding cooperation between the cooling pipe 241 and the sliding sleeve 512, the support frame rod 51 is in a state of rotation with the hinge seat 511 as the axis.

[0066] As the first curtain sheet 22 and the second curtain sheet 23 are gradually unfolded, the cooling pipe 241 moves synchronously. The sliding sleeve 512 on the cooling pipe 241 slides along with the movement of the cooling pipe 241. The sliding sleeve 512 slides along the cooling pipe 241, causing the support frame rod 51 to rotate around the hinge seat 511 as the axis.

[0067] When the movable roller 222 moves to the bottom of the frame 21, the cooling pipe 241 also moves to the bottom position. The support frame rod 51 is finally deployed in the cooling space 24, ensuring that the elastic buffer 52 is evenly distributed during the deployment of the first curtain sheet 22, better absorbing and dispersing the impact force, and reducing the situation of excessive local force.

[0068] See also Figure 6-Figure 12 As shown, the elastic buffer 52 is composed of a pressure rod 521 and a buffer spring 522. The end of the pressure rod 521 contacts the inner surface of the first curtain piece 22. A rod sleeve 5211 is fixedly provided on the support frame rod 51 for the pressure rod 521 to be inserted therein. The buffer spring 522 is fixedly arranged between the pressure rod 521 and the rod sleeve 5211. When the first curtain piece 22 is impacted by a heat wave, the pressure rod 521 is subjected to an extrusion force, so that the buffer spring 522 is in a compressed state.

[0069] When the first curtain piece 22 is impacted by a heat wave, the pressure generated by the heat wave acts on the first curtain piece 22. After the first curtain piece 22 is compressed, it transmits the pressure to the pressing rod 521 in contact with its inner surface. After the pressing rod 521 is squeezed, it moves toward the inside of the rod sleeve 5211. The buffer spring 522 is compressed, absorbing and dispersing part of the impact force.

[0070] When the heat wave impact weakens or disappears, the buffer spring 522 will gradually return to a state without external force due to its elastic characteristics. The pressing rod 521 will then return to the initial position and always keep in contact with the inner surface of the first curtain sheet 22, effectively resisting the impact of the heat wave and protecting the first curtain sheet 22 from damage.

[0071] See also Fig.12 As shown, the end of the pressing rod 521 that contacts the inner surface of the first curtain sheet 22 is a round head structure.

[0072] The round head structure of the pressing rod 521 can reduce the friction between the pressing rod 521 and the inner surface of the first curtain sheet 22 , thereby reducing the wear between the two, which helps to extend the service life of the first curtain sheet 22 .

[0073] Compared with a sharp or flat end, a round end can better disperse the stress points, thereby preventing the first curtain sheet 22 from being deformed or damaged due to excessive local stress.

[0074] See also Figure 6-Figure 9 and Fig.13 As shown, the water curtain generator 3 is specifically a tubular structure, and the water curtain generator 3 is arranged on the frame 21 and is located near the drum 221. The axial direction of the water curtain generator 3 is parallel to the axial direction of the drum 221, and the bottom of the water curtain generator 3 is provided with a flow channel 31 that fits with the outer surface of the first curtain sheet 22 along its axial direction.

[0075] The frame 21 is provided with an adaptive component 32 for ensuring that the flow channel 31 of the water curtain generator 3 always fits the outer surface of the first curtain sheet 22 during the unwinding process.

[0076] The adaptive component 32 includes a guide rail 321 and an elastic pull rope 322. The guide rail 321 is fixedly arranged on the frame 21. The track direction of the guide rail 321 is perpendicular to the unfolding direction of the first curtain sheet 22. The end of the water curtain generator 3 is fixedly connected with a movable guide wheel 3211 slidably arranged in the guide rail 321. The guide rail 321 has a fixed guide wheel 3212. The elastic pull rope 322 is a closed loop structure. The elastic pull rope 322 is sleeved between the movable guide wheel 3211 and the fixed guide wheel 3212.

[0077] When the first curtain sheet 22 is rolled up, the thickness of the first curtain sheet 22 on the drum 221 gradually increases, pushing the water curtain generator 3 to move outward along the guide rail 321. At this time, the elastic pull rope 322 is in a gradually stretched state, thereby ensuring that the flow channel 31 and the outer surface of the first curtain sheet 22 are always in a fit state, and does not hinder the drum 221 from rolling up the first curtain sheet 22.

[0078] When the first curtain sheet 22 is unrolled, the thickness of the first curtain sheet 22 on the drum 221 gradually becomes thinner, and the elastic pull rope 322 gradually recovers to a state without external force, pulling the water curtain generator 3 to move inward along the guide rail 321, while keeping the flow channel 31 in contact with the outer surface of the first curtain sheet 22. The water film generation effect on the surface of the first curtain sheet 22 is improved, and the fire isolation and water flow fire extinguishing capabilities are enhanced.

[0079] See also Figure 6-Figure 9 and Fig.13 As shown, the steam ejector 4 has a plurality of spray pipes 41 fixedly arranged thereon at equal intervals along the axial direction of the water curtain generator 3 .

[0080] The nozzles 41 are arranged at equal intervals to ensure that the steam is evenly distributed along the length of the entire water curtain generator 3, thereby avoiding the situation where the steam is too concentrated in some areas and insufficient in other areas, thereby improving the overall steam coverage effect.

[0081] Through the evenly distributed nozzles 41, steam can be sprayed more comprehensively toward the fire, forming a stable steam layer, thereby better diluting the oxygen in the air, inhibiting the combustion process, and helping to control the spread of the fire.

[0082] The present invention continuously monitors the environment through the smoke sensor 11 and the inspection robot infrared camera 12. Once a fire is detected, the emergency procedure is immediately started to drive the drum 221 to unfold the first curtain piece 22 and the second curtain piece 23 to form a multi-layer protection and create a cooling space 24. At the same time, the water curtain generator 3, the steam ejector 4, the cooling pipe 241 and the carbon dioxide fire extinguishing robot 13 are activated to quickly reduce the temperature, block the spread of flames and extinguish the fire. As the first curtain piece 22 and the second curtain piece 23 are unfolded, the elastic buffer 52 and the torsion spring 223 in the sleeve part 2223 work together to significantly reduce the impact force of the heat wave on the first curtain piece 22, improve the stability and impact resistance of the first curtain piece 22 after unfolding, and thus significantly enhance the effect of fire isolation.

[0083] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
