Description

Technical Field

[0001] The invention belongs to the technical field of alarm devices, and in particular relates to an anti-leakage alarm device for benzoyl chloride. Background Art

[0002] Benzoyl chloride is an organic compound, a colorless fuming liquid that is flammable, toxic and highly corrosive. Once a leak occurs, it not only threatens the lives of workers but also easily causes a fire. The leak of benzoyl chloride often occurs at the connection of the delivery pipe.

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

[0004] The above technology slows down the volatilization or diffusion of benzoyl chloride by spraying water mist, but benzoyl chloride reacts with water to release heat and produce toxic corrosive gases. In the actual leakage treatment process, it is strictly forbidden for water to contact benzoyl chloride. Therefore, the practicality is low, and the existing technology is not suitable for fixing on the delivery pipe, and the leakage cannot be detected in the first time, resulting in delayed alarm.

A limiting groove is provided on the outer wall of the transmission chamber, and a bracket two is rotatably sleeved on the outer wall of the output end of the electric push rod through a bearing, and the bracket two is slidably inserted in the limiting groove, and a rack is welded on the end of the bracket two, and the rack is meshed with gear three. An emergency mechanism is provided in the ash storage chamber.

[0007] In the above-mentioned benzoyl chloride leakage prevention alarm device, clamping grooves are provided on the bottom outer walls at both ends of the shell, and a clamping ring is connected to the outer wall of the shell near the clamping groove by bolts. The clamping groove and the clamping ring can clamp the pipeline, and supporting feet are welded on the outer walls at both ends of the shell.

[0008] In the above-mentioned benzoyl chloride leakage prevention alarm device, guide helical teeth are welded on the outer wall of the gear 2 and the gear 1 on the side close to each other, and the guide helical teeth correspond to the gear teeth one by one.

[0009] In the above-mentioned benzoyl chloride leakage alarm device, the sealing groove and the sealing ring are both compatible with the pipeline flange, the sealing groove and the sealing ring are both semicircular, and the worm wheel ring is three-quarters of a circle, so that the pipeline can be avoided during installation.

[0010] In the above-mentioned anti-leakage alarm device for benzoyl chloride, the emergency mechanism includes a stirring frame, a stirring frame is rotatably inserted on the inner wall of the ash storage chamber close to the transmission chamber, a wedge block 2 is welded on the outer wall of one end of the stirring frame extending to the transmission chamber, a wedge block 1 is welded on the outer wall of the electric push rod close to the second bracket, the wedge block 1 is matched with the wedge block 2, a ratchet is welded on the main shaft of the motor, and the ash storage chamber is filled with lime powder.

[0011] In the above-mentioned benzoyl chloride leakage prevention alarm device, the main shaft of the motor passes through the stirring frame, an installation chamber is opened inside the stirring frame, the ratchet is rotatably inserted in the installation chamber, a plurality of spring pieces are welded in the installation chamber, the spring pieces are unidirectionally clamped with the ratchet, and three ash spreading openings equidistantly distributed in a circle are opened on the inner wall of the ash storage chamber.

[0012] In the above-mentioned anti-leakage alarm device for benzoyl chloride, three equidistant circumferentially distributed inclined blocks are welded on the inner wall of the ash storage chamber, the inclined blocks correspond to the ash spreading ports one by one, and the end of the inclined block close to the ash spreading port gradually approaches the center of the ash storage chamber, and three equidistant circumferentially distributed mounting grooves are opened on the outer wall of the stirring frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The clamping groove and clamping ring are provided so that the device can be fixed at the flange connection of the pipeline. Once benzoyl chloride leaks and smokes, the fan is driven by the forward rotation of the motor to blow the smoke toward 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 tendency of leakage to spread; 2. By setting the sealing groove and sealing ring, during installation, 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 retract, so that gear one and gear two are disengaged, so that the fan loses the power source and stops rotating, avoiding the airflow from driving the benzoyl chloride to diffuse. At the same time, the electric push rod drives the rack to move, so that the gear three meshing with it drives the worm to rotate, so that the worm drives the worm wheel 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 close the pipe flange connection, preventing the benzoyl chloride from further leaking, and achieving the effect of cutting off the leakage point; 3. Through the emergency mechanism set up, when the smoke detector triggers the alarm, the smoke detector will also control the motor to reverse, and the electric push rod will drive the wedge block 1 to buckle with the wedge block 2 when it contracts, so that the motor can drive the stirring frame to rotate, so as to achieve 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 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 is separated from the inclined block, under the action of the spring, the push plate quickly resets, so that the push plate can push the lime powder to the ash spreading port, so as to achieve the effect of ash spreading to the surroundings. The hygroscopicity of the lime powder absorbs the leaked benzoyl chloride to prevent it from flowing and spreading. At the same time, the lime powder can neutralize the acid and alkali with the benzoyl chloride, which is convenient for subsequent treatment. In addition, the lime powder is a non-combustible material, so that the coverage of the lime powder has a certain fire extinguishing effect. In summary, by setting the clamping groove and the clamping ring, the device can be fixed on the pipe flange connection. The device directly detects at the possible leakage point, responds promptly, and reduces the tendency of leakage spread. By setting the sealing groove and the sealing ring, the worm drives the worm wheel 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 close the pipe flange connection, prevent further leakage of benzoyl chloride, and achieve the effect of cutting off the leakage point.

A limit groove 121 is provided on the outer wall of the transmission chamber 12, and a bracket 2 5 is rotatably sleeved on the outer wall of the output end of the electric push rod 21 through a bearing, and the bracket 2 5 is slidably plugged into the limit groove 121. A rack 51 is welded on the end of the bracket 2 5, and the rack 51 meshes with the gear 3 6. An emergency mechanism is provided in the ash storage chamber 11, and a clamping groove 1 is provided on the outer wall of the bottom of both ends of the shell 1 3. A clamping ring 14 is connected to the outer wall of the housing 1 near the clamping groove 13 by bolts. The clamping groove 13 and the clamping ring 14 can clamp the pipeline. Support legs 15 are welded on the outer walls of both ends of the housing 1. A guide bevel tooth 32 is welded on the outer wall of one side where the gear 2 3 and the gear 1 221 are close to each other. The guide bevel tooth 32 corresponds to the gear teeth one by one. The sealing groove 16 and the sealing ring 4 are both compatible with the pipeline flange. The sealing groove 16 and the sealing ring 4 are both semicircular, and the worm wheel ring 42 is three-quarters of a circle, so that the pipeline can be avoided during installation.

[0028] In the initial state, the electric push rod 21 is in an extended state, the gear 1 221 and the gear 2 3 are meshed with each other, and the sealing ring 4 is received in the sealing groove 16 .

[0029] The above content is further elaborated: during installation, the pipe is clamped by the clamping groove 13 and the clamping ring 14, so that the device can be fixed at the pipe flange connection, and the pipe flange is clamped in the sealing groove 16, and the motor 2 is controlled to rotate forward to drive the fan 31 to rotate. Once the benzoyl chloride leaks and smokes, the fan 31 can blow the smoke to the smoke detector 17, so that the smoke detector 17 can trigger the alarm 18 in time to alarm, and the reaction is timely, which reduces the tendency of leakage diffusion. At the same time, in the above process, when the smoke detector 17 triggers the alarm, the smoke detector 18 17 will also control the electric push rod 21 to contract, so that the gear 1 221 is disengaged from the gear 2 3, so that the fan 31 loses the power source and stops rotating, thereby preventing the airflow from driving the benzoyl chloride to diffuse. In addition, when the electric push rod 21 contracts, it drives the rack 51 to move, so that the gear 3 6 meshing with it drives the worm 61 to rotate, so that the worm 61 drives the worm wheel 42 to drive the sealing ring 4 to rotate, and the sealing ring 4 rotates out of the sealing groove 16, so that the sealing groove 16 and the sealing ring 4 can seal the pipeline flange connection, prevent further leakage of benzoyl chloride, and achieve the effect of cutting off the leakage point.

[0030] In addition, the device can also be fixed at a lower place on the ground by the support legs 15. Since the smoke density of formyl chloride leakage is greater than that of air, the smoke gathers in low-lying areas, thereby triggering the smoke detector 17 to alarm. The device has a wide range of usage scenarios and improves the practicality of the device.

[0031] Specifically, the emergency mechanism includes a stirring frame 7, a stirring frame 7 is rotatably inserted on the inner wall of the ash storage chamber 11 near the transmission chamber 12, a wedge 2 73 is welded on the outer wall of one end of the stirring frame 7 extending to the transmission chamber 12, a wedge 1 222 is welded on the outer wall of the electric push rod 21 near the bracket 2 5, the wedge 1 222 is adapted to the wedge 2 73, a ratchet 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 passes through the stirring frame 7, an installation chamber 71 is opened inside the stirring frame 7, the ratchet 22 is rotatably inserted in the installation chamber 71, a plurality of spring pieces 72 are welded in the installation chamber 71, the spring pieces 72 are unidirectionally clamped with the ratchet 22, and the ash storage chamber 11 The inner wall of the ash storage chamber 11 is provided with three equidistant circumferentially distributed ash openings 111, and the inner wall of the ash storage chamber 11 is welded with three equidistant circumferentially distributed inclined blocks 112, the inclined blocks 112 correspond to the ash spreading openings 111 one by one, and the end of the inclined block 112 close to the ash spreading opening 111 gradually approaches the center of the ash storage chamber 11, and the outer wall of the stirring frame 7 is provided with three equidistant circumferentially distributed mounting grooves 74, each of which is slidably inserted with a special-shaped column 81, and a spring 82 is welded between the end wall of each special-shaped column 81 and the inner wall of the mounting groove 74, and a push plate 8 is welded on the outer wall of the end of each special-shaped column 81 away from the spring 82, and the push plate 8 is adapted to the ash spreading opening 111 and the inclined block 112.

[0032] 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 spring piece 72 will not engage, so that the stirring frame 7 does not rotate. When formyl chloride leaks, the motor 2 rotates reversely, and the ratchet 22 and the spring piece 72 engage, so that the ratchet 22 drives the stirring frame 7 to rotate, thereby achieving the ash spreading effect.

[0033] The above emergency mechanism is further explained as follows: when the smoke detector 17 triggers an alarm, the smoke detector 17 will also control the motor 2 to reverse, and the electric push rod 21 will drive the wedge block 1 222 to engage with the wedge block 2 73 when it contracts, so that the motor 2 can drive the stirring frame 7 to rotate, thereby 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 contacts the inner wall of the ash storage chamber 11. When the push plate 8 contacts the inclined block 112, the push plate 8 is pushed. The plate 8 gradually compresses the spring 82 along the inclined block 112. When the push plate 8 is separated from the inclined block 112, the push plate 8 is quickly reset under the action of the spring 82, so that the push plate 8 can push the lime powder to the ash spreading port 111, thereby achieving the effect of spreading ash around. The leaked benzoyl chloride is absorbed by the hygroscopicity of the lime powder to prevent it from flowing and spreading. At the same time, the lime powder can neutralize the acid and alkali with the benzoyl chloride, which is convenient for subsequent treatment. In addition, the lime powder is non-combustible, so the coverage of the lime powder has a certain fire extinguishing effect.

[0034] The working principle and use process of the present invention are as follows: during installation, the pipe is clamped by the clamping groove 13 and the clamping ring 14, so that the device can be fixed at the pipe flange connection, and the pipe flange is clamped in the sealing groove 16, and the motor 2 is controlled to rotate forward to drive the fan 31 to rotate. Once benzoyl chloride leaks and smokes, the fan 31 can blow the smoke to the smoke detector 17, so that the smoke detector 17 can trigger the alarm 18 in time to alarm, and the reaction is timely, which reduces the tendency of leakage diffusion, and the smoke detector 17 can also control the electric push rod 21 to contract, so that the worm The worm wheel 42 driven by 61 drives the sealing ring 4 to rotate, and the sealing ring 4 rotates out of the sealing groove 16, so that the sealing groove 16 and the sealing ring 4 can seal the pipe flange connection, prevent the benzoyl chloride from further leaking, and achieve the effect of cutting off the leakage point. At the same time, in the above process, under the action of the emergency mechanism, the push plate 8 can push the lime powder to the ash spreading port 111, so as to achieve the effect of spreading ash around, and the leaked benzoyl chloride is absorbed and neutralized by the lime powder to prevent it from flowing and spreading, and the coverage of the lime powder has a certain fire extinguishing effect, which is convenient for subsequent treatment.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
