Description

Technical Field

[0001] The present invention belongs to the technical field of alarm devices, and particularly relates to a leakage prevention alarm device for benzoyl chloride. Background Art

[0002] Benzoyl chloride is an organic compound, a colorless fuming liquid, with flammability, toxicity and strong corrosiveness. Once a leakage occurs, it not only threatens the lives of staff, but also easily causes fires. The leakage of benzoyl chloride often occurs at the connection of the conveying pipe.

[0003] The prior art such as a leakage prevention detection device for benzoyl chloride with the patent number CN202121682420.4 includes a mounting base. The mounting base is a horizontally placed circle, and support columns are fixedly connected to the four corners of the bottom of the mounting base. The bottom of the support column is fixedly connected to a support base, and a servo motor is fixedly connected to the top of the support base. The bottom of the servo motor is fixedly connected to a fixed shaft, and a photoelectric smoke alarm is fixedly connected to the bottom of the fixed shaft. A control center is provided at the inner bottom end of the fixed shaft. The utility model has the advantages of simple structure, convenient operation and wide application range. By setting a photoelectric smoke alarm to detect benzoyl chloride, the detection is more comprehensive. Once benzoyl chloride leaks and smokes in the air, after the photoelectric smoke alarm alarms, the solenoid valve is started, and the atomizing nozzle sprays water mist to slow down the volatilization or diffusion of benzoyl chloride, and can make timely treatment after the leakage of benzoyl chloride, reduce potential safety hazards and improve safety efficiency.

[0004] The above technology slows down the volatilization or diffusion of benzoyl chloride by spraying water mist. However, benzoyl chloride reacts with water exothermically and produces toxic corrosive gases. In the actual leakage treatment process, it is necessary to strictly prohibit water from contacting benzoyl chloride. Therefore, the practicality is low, and the prior art is not suitable for being fixed on the conveying pipe and cannot detect the leakage situation in the first time, resulting in untimely alarm. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background art, and a leakage prevention alarm device for benzoyl chloride is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] An anti-leakage alarm device for benzoyl chloride, comprising a housing. A dust storage chamber and a transmission chamber are provided at the top of the housing. A motor is welded to the outer wall of the dust storage chamber. The main shaft of the motor penetrates through the dust storage chamber and extends into the transmission chamber. An electric push rod is welded to the main shaft of the motor. A first gear is welded to the outer wall of the output end of the electric push rod. A second gear is rotatably inserted through the outer wall of the housing near the transmission chamber by a rotating shaft. The second gear is adapted to the first gear. A fan is welded to the rotating shaft of the second gear. A smoke detector is adhesively bonded to the inner wall of the housing away from the fan. An alarm is fixed to the outer wall of the housing near the motor. The smoke detector is electrically connected to the alarm, the motor and the electric push rod. A sealing groove is provided on the bottom inner wall of the housing. A sealing ring is slidably inserted into the sealing groove. A first support is welded to the outer wall of the sealing ring. A worm gear ring is welded to the end of the first support. The worm gear ring extends into the transmission chamber. A third gear is rotatably inserted through the outer wall of the transmission chamber by a rotating shaft. A worm is welded to the rotating shaft of the third gear. The worm is meshed with the worm gear ring. A limiting groove is provided on the outer wall of the transmission chamber. A second support is rotatably sleeved on the outer wall of the output end of the electric push rod through a bearing. The second support is slidably inserted into the limiting groove. A rack is welded to the end of the second support. The rack is meshed with the third gear. An emergency mechanism is arranged in the dust storage chamber.

[0008] In the above anti-leakage alarm device for benzoyl chloride, clamping grooves are provided on the bottom outer walls at both ends of the housing. A clamping ring is connected to the outer wall of the housing near the clamping groove by bolts. The clamping grooves and the clamping ring can clamp the pipeline. Support feet are welded to the outer walls at both ends of the housing.

[0009] In the above anti-leakage alarm device for benzoyl chloride, guiding inclined teeth are welded to the outer walls on the sides where the second gear and the first gear are close to each other. The guiding inclined teeth correspond to the teeth of the gear one by one.

[0010] In the above anti-leakage alarm device for benzoyl chloride, both the sealing groove and the sealing ring are adapted to the pipeline flange. Both the sealing groove and the sealing ring are semi-circular. The worm gear ring is three-quarters circular and can avoid the position of the pipeline during installation.

[0011] In the above anti-leakage alarm device for benzoyl chloride, the emergency mechanism includes a stirring frame. A stirring frame is rotatably inserted through the inner wall on one side of the dust storage chamber close to the transmission chamber. A second wedge block is welded to the outer wall of the end of the stirring frame extending into the transmission chamber. A first wedge block is welded to the outer wall of the electric push rod close to the second support. The first wedge block is adapted to the second wedge block. A ratchet is welded to the main shaft of the motor. Lime powder is filled in the dust storage chamber.

[0012] In the above anti-leakage alarm device for benzoyl chloride, the main shaft of the motor penetrates through the stirring frame. An installation chamber is provided inside the stirring frame. The ratchet wheel is rotatably inserted into the installation chamber. A plurality of elastic pieces are welded in the installation chamber. The elastic pieces are in one-way clamping connection with the ratchet wheel. Three ash-spreading openings are provided on the inner wall of the ash storage chamber at equal intervals in a circumferential distribution.

[0013] In the above anti-leakage alarm device for benzoyl chloride, three inclined blocks are welded on the inner wall of the ash storage chamber at equal intervals in a circumferential distribution. The inclined blocks correspond to the ash-spreading openings one by one. One end of the inclined block close to the ash-spreading opening gradually approaches the center of the ash storage chamber. Three installation grooves are provided on the outer wall of the stirring frame at equal intervals in a circumferential distribution.

[0014] In the above anti-leakage alarm device for benzoyl chloride, a special-shaped column is slidably inserted into each installation groove. A spring is welded between the end wall of each special-shaped column and the inner wall of the installation groove. A push plate is welded on the outer wall of each special-shaped column far away from the spring. The push plate is adapted to both the ash-spreading opening and the inclined block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By providing the clamping groove and the clamping ring, the device can be fixed at the pipe flange connection. Once benzoyl chloride leaks and smokes, the motor rotates forward to drive the fan to rotate, realizing the effect of blowing the smoke towards the smoke detector, so that the smoke detector can trigger the alarm in time. The device directly detects at the possible leakage point, responds in time, and reduces the trend of leakage diffusion.

[0017] 2. By providing the sealing groove and the sealing ring, when installing, the pipe flange is clamped in the sealing groove. When the smoke detector triggers the alarm, the smoke detector will also control the electric push rod to contract, so that the first gear disengages from the second gear, so that the fan loses the power source and stops rotating, avoiding the diffusion of benzoyl chloride driven by the air flow. At the same time, the electric push rod drives the rack to move, so that the third gear meshing with it drives the worm to rotate, so that the worm drives the worm gear ring to drive the sealing ring to rotate, and the sealing ring rotates out of the sealing groove, so that the sealing groove and the sealing ring can seal the pipe flange connection and prevent further leakage of benzoyl chloride, realizing the effect of cutting off the leakage point.

[0018] 3. Through the set emergency mechanism, when the smoke detector triggers an alarm, the smoke detector will also control the motor to reverse. When the electric push rod contracts, it drives the first wedge block to engage with the second wedge block, enabling the motor to drive the stirring frame to rotate, achieving the effect of stirring the lime powder in the ash storage chamber. At the same time, the stirring frame drives the push plate to rotate. Under the action of the spring, the push plate always abuts against the inner wall of the ash storage chamber. When the push plate abuts against the inclined block, the push plate gradually compresses the spring along the inclined block. When the push plate disengages from the inclined block, under the action of the spring, the push plate quickly resets, enabling the push plate to push the lime powder towards the ash spreading opening, achieving the effect of spreading ash around. The hygroscopicity of the lime powder is used to absorb the leaked benzoyl chloride, preventing it from flowing and spreading. At the same time, the lime powder can undergo acid-base neutralization with benzoyl chloride, facilitating subsequent treatment. Moreover, since the lime powder is non-combustible, the coverage of the lime powder has a certain fire extinguishing effect.

[0019] In summary, through the set clamping groove and clamping ring, the device can be fixed at the pipe flange connection. The device directly detects at the possible leakage point, responds in a timely manner, and reduces the tendency of leakage and diffusion. Through the set sealing groove and sealing ring, the worm drives the worm gear ring to drive the sealing ring to rotate, and the sealing ring rotates out of the sealing groove. Furthermore, the sealing groove and the sealing ring can seal the pipe flange connection, preventing further leakage of benzoyl chloride and achieving the effect of cutting off the leakage point.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0032] Please refer to Figures 1-9, the present invention provides a technical solution: a leakage prevention and alarm device for benzoyl chloride, including a housing 1. A dust storage chamber 11 and a transmission chamber 12 are provided at the top of the housing 1. A motor 2 is welded on the outer wall of the dust storage chamber 11. The main shaft of the motor 2 penetrates through the dust storage chamber 11 and extends to the transmission chamber 12. An electric push rod 21 is welded on the main shaft of the motor 2. A first gear 221 is welded on the outer wall of the output end of the electric push rod 21. A second gear 3 is rotatably inserted through a rotating shaft on the outer wall of the housing 1 close to the transmission chamber 12. The second gear 3 is adapted to the first gear 221. A fan 31 is welded on the rotating shaft of the second gear 3. A smoke detector 17 is adhesively bonded on the inner wall of the housing 1 away from the fan 31. An alarm 18 is fixed on the outer wall of the housing 1 close to the motor 2. The smoke detector 17 is electrically connected to the alarm 18, the motor 2 and the electric push rod 21. A sealing groove 16 is provided on the bottom inner wall of the housing 1. A sealing ring 4 is slidably inserted in the sealing groove 16. A first support 41 is welded on the outer wall of the sealing ring 4. A worm gear ring 42 is welded at the end of the first support 41. The worm gear ring 42 extends into the transmission chamber 12. A third gear 6 is rotatably inserted through a rotating shaft on the outer wall of the transmission chamber 12. A worm 61 is welded on the rotating shaft of the third gear 6. The worm 61 meshes with the worm gear ring 42. A limiting groove 121 is provided on the outer wall of the transmission chamber 12. A second support 5 is rotatably sleeved on the outer wall of the output end of the electric push rod 21 through a bearing. The second support 5 is slidably inserted in the limiting groove 121. A rack 51 is welded at the end of the second support 5. The rack 51 meshes with the third gear 6. An emergency mechanism is provided in the dust storage chamber 11. Clamping grooves 13 are provided on the bottom outer walls at both ends of the housing 1. A clamping ring 14 is bolted on the outer wall of the housing 1 close to the clamping grooves 13. The clamping grooves 13 and the clamping ring 14 can clamp the pipeline. Support feet 15 are welded on the outer walls at both ends of the housing 1. Guide bevel gears 32 are welded on the outer walls of the mutually approaching sides of the second gear 3 and the first gear 221. The guide bevel gears 32 correspond to the gear teeth one by one. The sealing groove 16 and the sealing ring 4 are both adapted to the pipeline flange. The sealing groove 16 and the sealing ring 4 are both semi-circular. The worm gear ring 42 is three-quarters circular and can avoid the position of the pipeline during installation.

[0033] In the initial state, the electric push rod 21 is in the extended state. The first gear 221 meshes with the second gear 3. The sealing ring 4 is received in the sealing groove 16.

[0034] For further elaboration on the above content: During installation, the pipe is clamped by the clamping groove 13 and the clamping ring 14, enabling the device to be fixed at the pipe flange connection. And the pipe flange is clamped in the sealing groove 16. Control the motor 2 to rotate forward to drive the fan 31 to rotate. Once benzoyl chloride leaks and smokes, the fan 31 can blow the smoke towards the smoke detector 17, so that the smoke detector 17 can promptly trigger the alarm 18 to give an alarm, with timely response and reduced tendency of leakage diffusion. At the same time, during the above process, when the smoke detector 17 triggers the alarm, the smoke detector 17 will also control the electric push rod 21 to contract, causing the first gear 221 to disengage from the second gear 3, so that the fan 31 loses the power source and stops rotating, avoiding the airflow from driving the diffusion of benzoyl chloride. Moreover, when the electric push rod 21 contracts, it drives the rack 51 to move, causing the third gear 6 meshing with it to drive the worm 61 to rotate, so that the worm 61 drives the worm gear ring 42 to drive the sealing ring 4 to rotate. The sealing ring 4 rotates out of the sealing groove 16, and further enables the sealing groove 16 and the sealing ring 4 to seal the pipe flange connection, preventing further leakage of benzoyl chloride and achieving the effect of cutting off the leakage point.

[0035] In addition, the device can also be fixed at a lower position on the ground through the feet 15. Since the density of the smoke generated by the leakage of formyl chloride is greater than that of air, the smoke converges towards the low-lying areas, thus enabling the smoke detector 17 to trigger the alarm, with a wide range of usage scenarios and improved practicality of the device.

[0036] Specifically, the emergency mechanism includes a stirring frame 7. The stirring frame 7 is rotationally inserted into the inner wall of the ash storage chamber 11 close to the transmission chamber 12. One end of the stirring frame 7 extending into the transmission chamber 12 is welded with a second wedge block 73 on the outer wall. The outer wall of the electric push rod 21 close to the second support 5 is welded with a first wedge block 222. The first wedge block 222 is adapted to the second wedge block 73. A ratchet wheel 22 is welded on the main shaft of the motor 2. The ash storage chamber 11 is filled with lime powder. The main shaft of the motor 2 penetrates through the stirring frame 7. An installation chamber 71 is opened inside the stirring frame 7. The ratchet wheel 22 is rotationally inserted into the installation chamber 71. A plurality of elastic pieces 72 are welded inside the installation chamber 71. The elastic pieces 72 are unidirectionally clamped with the ratchet wheel 22. Three equally spaced and circumferentially distributed ash spreading openings 111 are opened on the inner wall of the ash storage chamber 11. Three equally spaced and circumferentially distributed inclined blocks 112 are welded on the inner wall of the ash storage chamber 11. The inclined blocks 112 correspond to the ash spreading openings 111 one by one. One end of the inclined block 112 close to the ash spreading opening 111 gradually approaches the center of the ash storage chamber 11. Three equally spaced and circumferentially distributed installation grooves 74 are opened on the outer wall of the stirring frame 7. Each installation groove 74 is slidably inserted with a special-shaped column 81. A spring 82 is welded between the end wall of each special-shaped column 81 and the inner wall of the installation groove 74. A push plate 8 is welded on the outer wall of each special-shaped column 81 away from the spring 82. The push plate 8 is adapted to both the ash spreading opening 111 and the inclined block 112.

[0037] In the initial state, the push plate 8 closes the ash spreading opening 111. When the motor 2 rotates forward, the ratchet 22 and the elastic piece 72 will not engage, so that the stirring frame 7 does not rotate. When phosgene leaks, the motor 2 rotates in reverse, and the ratchet 22 and the elastic piece 72 engage, causing the ratchet 22 to drive the stirring frame 7 to rotate, achieving the effect of spreading ash.

[0038] For further elaboration on the above emergency mechanism: When the smoke detector 17 triggers an alarm, the smoke detector 17 also controls the motor 2 to rotate in reverse. When the electric push rod 21 contracts, it drives the wedge block one 222 to engage with the wedge block two 73, so that the motor 2 can drive the stirring frame 7 to rotate, achieving the effect of stirring the lime powder in the ash storage chamber 11. At the same time, the stirring frame 7 drives the push plate 8 to rotate. Under the action of the spring 82, the push plate 8 always abuts against the inner wall of the ash storage chamber 11. When the push plate 8 abuts against the inclined block 112, the push plate 8 gradually compresses the spring 82 along the inclined block 112. When the push plate 8 disengages from the inclined block 112, under the action of the spring 82, the push plate 8 quickly resets, enabling the push plate 8 to push the lime powder towards the ash spreading opening 111, achieving the effect of spreading ash to the surroundings. The leaked benzoyl chloride is absorbed through the hygroscopicity of the lime powder, preventing it from flowing and spreading. At the same time, the lime powder can undergo acid-base neutralization with benzoyl chloride, facilitating subsequent treatment. Moreover, the lime powder is non-combustible, enabling the coverage of the lime powder to have a certain fire extinguishing effect.

[0039] The working principle and usage process of the present invention: During installation, the pipe is clamped through the clamping groove 13 and the clamping ring 14, enabling the device to be fixed at the pipe flange connection. And the pipe flange is clamped in the sealing groove 16. Control the motor 2 to rotate forward to drive the fan 31 to rotate. Once benzoyl chloride leaks and smokes, the fan 31 can blow the flue gas towards the smoke detector 17, so that the smoke detector 17 can promptly trigger the alarm 18 to give an alarm, with timely response and a reduced tendency of leakage and diffusion. And the smoke detector 17 also controls the electric push rod 21 to contract, causing the worm 61 to drive the worm gear ring 42 to drive the sealing ring 4 to rotate. The sealing ring 4 rotates out of the sealing groove 16, and then the sealing groove 16 and the sealing ring 4 can seal the pipe flange connection, preventing further leakage of benzoyl chloride and achieving the effect of cutting off the leakage point. At the same time, during the above process, under the action of the emergency mechanism, the push plate 8 can push the lime powder towards the ash spreading opening 111, achieving the effect of spreading ash to the surroundings. The leaked benzoyl chloride is absorbed and neutralized by the lime powder, preventing it from flowing and spreading, and the coverage of the lime powder has a certain fire extinguishing effect, facilitating subsequent treatment.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
