Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of benzoyl chloride detection, and particularly relates to a leakage detection device for benzoyl chloride. BACKGROUND

[0002] Benzoyl chloride (C7H5ClO) is a colorless smoky liquid with a strong irritating odor, which is easy to react with moisture in the air to generate benzoic acid and hydrogen chloride (HCl). Its physical properties include a melting point of-1 DEG C, a boiling point of 197-198 DEG C, a density of 1.21 g / cm3, and solubility in organic solvents such as diethyl ether and chloroform, but it will be hydrolyzed violently when it comes into contact with water, ethanol or ammonia. The compound is an important organic synthesis intermediate and is widely used in the preparation of benzoyl peroxide (a plastic polymerization initiator), dyes (such as indigo and direct fast red GB), medicines (such as procaine), pesticides (such as isoxazole phosphorus) and spices.

[0003] Since benzoyl chloride has certain toxicity, once it leaks, it will have certain impact on the surrounding personnel and environment. When the benzoyl chloride is transported by using a pipeline, the pipeline is prone to leakage. The current leakage detection method mainly installs smoke alarms on the outer side of the pipeline at every certain distance to realize leakage detection. This detection method needs a large number of smoke alarms, and cannot pretreat the leaked benzoyl chloride.

[0004] When benzoyl chloride leaks, the operator can be reminded of the leakage at the first time, but before the whole disposal, the benzoyl chloride is in a continuous leakage state, and the leakage point cannot be quickly treated to remove the residual benzoyl chloride, so that the overall safety is poor, and improvement is needed. SUMMARY

[0005] The application aims to provide a leakage detection device for benzoyl chloride to solve the problems in the background art.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical scheme: a leakage detection device for benzoyl chloride, comprising a frame, a mounting ring is fixedly installed at the bottom end of the frame, transverse guide rails are fixedly installed at both ends of the frame, a collecting box is fixedly installed on the inner side of the frame, a negative pressure pump is installed on the top of the collecting box, the output end of the negative pressure pump is connected to the collecting box, ear plates are installed on the front and rear sides near the middle of the transverse guide rails, an adjusting component is provided above the frame, the left and right sides of the bottom end of the adjusting component are movably engaged with the two transverse guide rails, the tops of the ear plates are fixedly installed with guide rods, the adjusting component is movably sleeved with the guide rods, a main power component is provided in the middle of the top end of the frame, the top of the main power component is fixedly connected with a three-way valve, the bottom end of the main power component is fixedly connected with a four-way valve, the bottom end of the four-way valve is connected to the input end of the negative pressure pump, mounting brackets are installed on the left and right sides of the bottom end of the adjusting component, and smoke alarms are installed on the bottom ends of the mounting brackets.

[0007] An exhaust valve is provided at the rear end of the collection box, which is in a normally open state when normal air is inhaled and in a normally closed state when benzoyl chloride leaks.

[0008] Before use, the mounting ring can be put on the outer side of the pipe and moved to the middle of the pipe, making sure that the two transverse guide rails can cover both sides of the pipe. At the same time, the mounting ring can be rotated to ensure that the two smoke alarms are located in front of the high-incidence point of leakage to complete the installation and adjustment.

[0009] As a further technical solution of the present invention, the main power assembly includes a power tank, a main shaft is movably mounted in the middle of the power tank, and an impeller located inside the power tank is fixedly sleeved on the outer side of the main shaft.

[0010] As a further technical solution of the present invention, the top of the power tank is connected to the bottom of the three-way valve, the bottom of the power tank is connected to the top of the four-way valve, and the front and rear ends of the main shaft pass through the front and rear ends of the power tank and are fixedly installed with a first rocker arm.

[0011] As a further technical solution of the present invention, one end of the first rocker arm away from the main shaft is movably connected to the second rocker arm via a rotating shaft, and the other end of the second rocker arm is connected to the adjustment assembly.

[0012] When conducting a leak test, the negative pressure pump can be turned on to generate negative pressure and suck external air into the interior of the three-way valve through the collection pipe. After entering the interior of the power tank through the three-way valve, the air is discharged through the four-way valve and enters the interior of the collection box, and is discharged through the exhaust valve at the rear end of the collection box. When the high-pressure air enters the interior of the power tank, it can drive the impeller to rotate. At this time, the main shaft rotates accordingly, and drives the first rocker arm on the outer side to rotate. At this time, the second rocker arm on the side of the first rocker arm swings accordingly.

[0013] As a further technical solution of the present invention, the adjustment component includes a movable plate, and guide holes are opened at the top of the movable plate near the four corners. The guide holes are movably connected to the guide rod, and the movable plate moves up and down relative to the guide rod. Installation shafts are installed at the front and rear ends of the middle of the guide hole.

[0014] As a further technical solution of the present invention, the mounting shaft is movably connected to the second rocker arm, and first fixing seats are installed on both sides of the left and right sides of the bottom end of the movable plate. The end of the first fixing seat away from the movable plate is movably connected to a connecting rod through a rotating shaft.

[0015] As a further technical solution of the present invention, the end of the connecting rod away from the first fixed seat is movably connected to the second fixed seat through a rotating shaft, and the bottom end of the second fixed seat is installed with a guide block, which is movably connected to the transverse guide rail, and the bottom end of the guide block is connected to the top of the mounting frame.

[0016] When the second swing arm swings, an upward pulling force and a downward pushing force can be applied to the mounting shaft. At this time, the movable plate can move downward or upward under the guidance of the guide rod, that is, perform up and down reciprocating motion. When the movable plate moves up, it can drive the first fixed seat to move up, and at the same time drive the two connecting rods to deflect toward the outer side, and drive the two guide blocks away from each other. When the movable plate moves down, it can drive the two guide blocks closer to each other, and finally drive the mounting bracket and the smoke alarm at the bottom end to move back and forth left and right, repeatedly scanning the possible leakage points of the pipeline.

[0017] By utilizing the cooperation between the main power component and the adjustment component and using the inhaled high-pressure air as power, the device can use a small number of smoke alarms under normal conditions to repeatedly scan a long pipe, so that it can quickly find the detection point. At the same time, there is no need to set up a large number of smoke alarms for monitoring, which effectively reduces the use of smoke alarms without reducing monitoring accuracy and reducing usage costs.

[0018] As a further technical solution of the present invention, a collecting pipe is clamped on the side of the mounting frame away from the frame, the input end of the collecting pipe is connected to one side of the three-way valve, and an auxiliary disposal component is fixedly installed on the side of the mounting frame close to the frame.

[0019] When the smoke alarm detects the leakage of benzoyl chloride, the exhaust valve at the rear end of the collection box is closed and the negative pressure pump is continuously started, so that the leaked benzoyl chloride can be sucked into the interior of the three-way valve through the collection pipe, and at the same time introduced into the interior of the collection box for temporary storage through the main power component and the four-way valve. The left and right reciprocating movement of the mounting frame can drive the collection pipe to move synchronously left and right to actively absorb the benzoyl chloride near the pipeline, completing the pretreatment process.

[0020] By utilizing the coordination of the regulating component and the main power component and taking advantage of the negative pressure effect of the negative pressure pump, the device can realize active scanning monitoring by inhaling normal air, and can also actively absorb benzoyl chloride when it leaks. The entire absorption covers a longer pipeline, which can effectively pre-treat the leaked benzoyl chloride, reduce the leakage of benzoyl chloride into the air, and improve safety.

[0021] As a further technical solution of the present invention, the auxiliary disposal component includes a sodium hydroxide storage tank, which is installed at the top of the mounting frame. The bottom end of the sodium hydroxide storage tank is fixedly connected to a pressure flap valve, and the output end of the pressure flap valve passes through the bottom end of the mounting frame. The top end of the sodium hydroxide storage tank is fixedly connected to a pressurized pipe, and the other end of the pressurized pipe is connected to the four-way valve.

[0022] When benzoyl chloride leaks, the valves on both sides of the four-way valve can be opened. At this time, part of the benzoyl chloride mixed with air can be discharged through the pressurized pipe and enter the interior of the sodium hydroxide storage tank, and pressure is applied to the sodium hydroxide inside the sodium hydroxide storage tank. At this time, the pressure of the sodium hydroxide increases, the valve of the pressure flap valve is opened, and the sodium hydroxide is discharged through the pressure flap valve and moved back and forth left and right through the mounting frame to cover the leakage point, thereby completing the treatment process of the residual benzoyl chloride.

[0023] By reusing the coordination of the regulating component and the main power component, and applying the mixture of actively inhaled benzoyl chloride and air as power to the auxiliary disposal component, the automatic extraction of sodium hydroxide can be achieved when benzoyl chloride leaks, and the extracted sodium hydroxide can be used to re-treat the residual benzoyl chloride, further reducing the pollution of the leaked benzoyl chloride to the surrounding environment, and realizing the simultaneous leakage monitoring and leakage treatment, thereby further improving safety.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the cooperation between the main power component and the regulating component and uses the inhaled high-pressure air as the power, so that the device can use a small number of smoke alarms to repeatedly scan a long pipe under normal conditions, so that it can quickly find the detection point. At the same time, there is no need to set up a large number of smoke alarms for monitoring, which effectively reduces the use of smoke alarms without reducing the monitoring accuracy and reducing the cost of use.

[0025] (2) The present invention utilizes the coordination of the regulating component and the main power component and the negative pressure effect of the negative pressure pump, so that the device can realize active scanning monitoring by inhaling normal air, and can also actively absorb benzoyl chloride when it leaks. The entire absorption covers a long pipeline, which can effectively pre-treat the leaked benzoyl chloride, reduce the leakage of benzoyl chloride into the air, and improve safety.

[0026] (3) The present invention reuses the coordination of the regulating component and the main power component, and applies the mixture of the actively inhaled benzoyl chloride and air as power to the auxiliary disposal component, thereby realizing the automatic extraction of sodium hydroxide when benzoyl chloride leaks, and using the extracted sodium hydroxide to re-treat the residual benzoyl chloride, further reducing the pollution of the leaked benzoyl chloride to the surrounding environment, and realizing the simultaneous leakage monitoring and leakage treatment, thereby further improving safety.

[0031] An exhaust valve is provided at the rear end of the collecting box 2, which is in a normally open state when normal air is inhaled, and is in a normally closed state when benzoyl chloride leaks.

[0032] Before use, the mounting ring 4 can be sleeved on the outer side of the pipe, and the mounting ring 4 can be moved to the middle of the pipe, and ensure that the two transverse guide rails 5 can cover both sides of the pipe. At the same time, the mounting ring 4 can be rotated to ensure that the two smoke alarms 13 are located directly in front of the high-incidence point of leakage, and the installation and adjustment work is completed.

[0033] like Figure 1 and Figure 6 as well as Figure 7 As shown, the main power component 9 includes a power tank 901, a main shaft 902 is movably installed in the middle of the power tank 901, and the outer side surface of the main shaft 902 is fixedly sleeved with an impeller 903 located inside the power tank 901. The top of the power tank 901 is connected to the bottom end of the three-way valve 10, and the bottom end of the power tank 901 is connected to the top of the four-way valve 11. The front and rear ends of the main shaft 902 pass through the front and rear ends of the power tank 901 and are fixedly installed with a first rocker arm 904. The end of the first rocker arm 904 away from the main shaft 902 is movably connected to the second rocker arm 905 through a rotating shaft, and the other end of the second rocker arm 905 is connected to the adjustment component 7.

[0034] When conducting a leak test, the negative pressure pump 3 can be turned on to generate negative pressure and suck external air into the interior of the three-way valve 10 through the collecting pipe 14. After entering the interior of the power tank 901 through the three-way valve 10, the air is discharged through the four-way valve 11, and enters the interior of the collecting box 2, and is discharged through the exhaust valve at the rear end of the collecting box 2. When the high-pressure air enters the interior of the power tank 901, the impeller 903 can be driven to rotate. At this time, the main shaft 902 rotates accordingly, and drives the first rocker arm 904 on the outer side to rotate. At this time, the second rocker arm 905 on the side of the first rocker arm 904 swings accordingly.

[0035] like Figure 1 and Figure 5 As shown, the adjustment component 7 includes a movable plate 701, and guide holes 706 are opened at the top of the movable plate 701 near the four corners. The guide holes 706 are movably connected to the guide rod 8, and the movable plate 701 moves up and down relative to the guide rod 8. The front and rear ends of the middle of the guide holes 706 are installed with mounting shafts 707, and the mounting shafts 707 are movably connected to the second rocker arm 905. The left and right sides of the bottom end of the movable plate 701 are installed with first fixed seats 702, and the end of the first fixed seat 702 away from the movable plate 701 is movably connected to the connecting rod 704 through a rotating shaft, and the end of the connecting rod 704 away from the first fixed seat 702 is movably connected to the second fixed seat 703 through a rotating shaft. The bottom end of the second fixed seat 703 is installed with a guide block 705, which is movably engaged with the transverse guide rail 5, and the bottom end of the guide block 705 is connected to the top of the mounting frame 12.

[0036] When the second swing arm 905 swings, an upward pulling force and a downward pushing force can be applied to the mounting shaft 707. At this time, the movable plate 701 can be displaced downward or upward under the guidance of the guide rod 8, that is, it can make an up and down reciprocating motion. When the movable plate 701 moves up, it can drive the first fixed seat 702 to move up, and at the same time drive the two connecting rods 704 to deflect toward the outer side, and drive the two guide blocks 705 away from each other. When the movable plate 701 moves down, it can drive the two guide blocks 705 to move closer to each other, and finally drive the mounting frame 12 and the smoke alarm 13 at the bottom to move back and forth left and right, repeatedly scanning the possible leakage points of the pipeline.

[0037] By utilizing the cooperation between the main power component 9 and the adjustment component 7 and using the inhaled high-pressure air as power, the device can use a small number of smoke alarms 13 under normal conditions to repeatedly scan a long pipeline, so that it can quickly find the detection point. At the same time, there is no need to set up a large number of smoke alarms 13 for monitoring, which effectively reduces the use of smoke alarms 13 without reducing monitoring accuracy and reducing usage costs.

[0038] like Figure 1 and Figure 3 as well as Figure 4 As shown, a collecting pipe 14 is clamped on the side of the mounting frame 12 away from the frame 1 , the input end of the collecting pipe 14 is connected to one side of the three-way valve 10 , and an auxiliary disposal assembly 15 is fixedly installed on the side of the mounting frame 12 close to the frame 1 .

[0039] Embodiment: When the smoke alarm 13 detects the leakage of benzoyl chloride, the exhaust valve at the rear end of the collection box 2 is closed, and the negative pressure pump 3 is continuously started, so that the leaked benzoyl chloride can be sucked into the interior of the three-way valve 10 through the collection pipe 14, and at the same time introduced into the interior of the collection box 2 for temporary storage through the main power component 9 and the four-way valve 11. The left and right reciprocating movement of the mounting frame 12 can drive the collection pipe 14 to move synchronously left and right to actively absorb the benzoyl chloride near the pipeline, completing the pretreatment process.

[0040] By utilizing the coordination of the regulating component 7 and the main power component 9 and the negative pressure effect of the negative pressure pump 3, the device can realize active scanning monitoring by inhaling normal air, and can also actively absorb benzoyl chloride when it leaks. The entire absorption covers a longer pipeline, which can effectively pre-treat the leaked benzoyl chloride, reduce the leakage of benzoyl chloride into the air, and improve safety.

[0041] like Figure 1 and Figure 4 As shown, the auxiliary disposal assembly 15 includes a sodium hydroxide storage tank 151, which is mounted on the top of the mounting frame 12. The bottom end of the sodium hydroxide storage tank 151 is fixedly connected to a pressure flap valve 152, and the output end of the pressure flap valve 152 passes through the bottom end of the mounting frame 12. The top end of the sodium hydroxide storage tank 151 is fixedly connected to a pressurized pipe 153, and the other end of the pressurized pipe 153 is connected to the four-way valve 11.

[0042] Embodiment: When benzoyl chloride leaks, the valves on both sides of the four-way valve 11 can be opened. At this time, part of the benzoyl chloride mixed with air can be exported through the pressurized pipe 153 and enter the interior of the sodium hydroxide storage tank 151, and pressure is applied to the sodium hydroxide inside the sodium hydroxide storage tank 151. At this time, the pressure of the sodium hydroxide increases, the valve of the pressure flap valve 152 is opened, and the sodium hydroxide is exported through the pressure flap valve 152 and moves back and forth left and right through the mounting frame 12 to cover the leakage point, completing the treatment process of residual benzoyl chloride.

[0043] By reusing the cooperation of the adjusting assembly 7 and the main power assembly 9, and by using the mixture of the benzoyl chloride and the air sucked actively as the power applied to the auxiliary treatment assembly 15, the automatic export of the sodium hydroxide when the benzoyl chloride leaks is realized, and the sodium hydroxide exported is used to treat the residual benzoyl chloride again, further reducing the pollution of the leaked benzoyl chloride to the surrounding environment, and realizing the simultaneous leakage monitoring and leakage treatment, further improving the safety.

[0044] Working principle and use process: Before use, the mounting ring 4 can be sleeved on the outer side of the pipeline, and the mounting ring 4 is moved to the middle of the pipeline, and it is ensured that the two transverse guide rails 5 can cover the two sides of the pipeline, and the mounting ring 4 is rotated to ensure that the two smoke alarms 13 are located in front of the high-leakage point, and the installation and adjustment work is completed; When detecting the leakage, the negative pressure pump 3 can be started to generate negative pressure and suck the external air into the inside of the three-way valve 10 through the collecting pipe 14, and then into the inside of the power tank 901 through the three-way valve 10, and then exported through the four-way valve 11 and into the inside of the collecting box 2, and then exported through the exhaust valve at the rear end of the collecting box 2. When the high-pressure air enters the inside of the power tank 901, it can drive the impeller 903 to rotate, at this time the main shaft 902 rotates and drives the first swing lever 904 on the outer side to rotate, at this time the second swing lever 905 on one side of the first swing lever 904 swings; When the second swing lever 905 swings, an upward pulling force and a downward pushing force can be applied to the mounting shaft 707 at this time, the movable plate 701 can be displaced downward or upward under the guidance of the guide rod 8, that is, it makes up-and-down reciprocating motion, when the movable plate 701 moves upward, it can drive the first fixed seat 702 to move upward, at the same time, the two connecting rods 704 are deflected outward, and the two guide blocks 705 are away from each other, and when the movable plate 701 moves downward, the two guide blocks 705 are close to each other, and finally the mounting bracket 12 at the bottom end and the smoke alarm 13 reciprocate left and right, and the possible leakage point of the pipeline is repeatedly scanned; When the smoke alarm 13 detects that benzoyl chloride leaks, the exhaust valve at the rear end of the collecting box 2 is closed at this time, and the negative pressure pump 3 is continuously started, which can suck the leaked benzoyl chloride into the inside of the three-way valve 10 through the collecting pipe 14, and then into the inside of the collecting box 2 through the main power assembly 9 and the four-way valve 11 for temporary storage, and through the left and right reciprocating displacement of the mounting bracket 12, the collecting pipe 14 can be driven to reciprocate left and right synchronously to actively suck the benzoyl chloride near the pipeline, and the pretreatment process is completed; When benzoyl chloride leaks, the valves on both sides of the four-way valve 11 can be opened. At this time, part of the benzoyl chloride mixed with air can be discharged through the pressurized pipe 153 and enter the interior of the sodium hydroxide storage tank 151, and pressure is applied to the sodium hydroxide inside the sodium hydroxide storage tank 151. At this time, the pressure of the sodium hydroxide increases, the valve of the pressure flap valve 152 is opened, and the sodium hydroxide is discharged through the pressure flap valve 152 and moves back and forth left and right through the mounting frame 12 to cover the leakage point, thereby completing the treatment process of residual benzoyl chloride.
