Description

Technical Field

[0001] The present invention relates to the technical field of oil transportation safety detection, and specifically discloses a safety production device for biomass liquid fuel. Background Art

[0002] As a viscous liquid fuel in a subdivision of biomass liquid fuel, marine oil products need to be transported through pipelines during their safe production process. For some long-distance transports, the pipelines often need to be sealed and connected by flanges. However, during the long-term transportation of marine oil products, leakage may occur at the pipeline flange joints due to various internal and external factors. Once the oil leakage cannot be detected in time, it poses a great risk to the safety of the entire marine oil product production.

[0003] The invention application with the application number 202310236742.3 discloses a pipeline leakage detection device for oil exploitation, including two oil pipelines. Flanges are fixedly connected to the inner sides of the two oil pipelines. A leakage alarm mechanism and a cleaning mechanism are arranged outside the two oil pipelines. The leakage alarm mechanism includes a sealing cylinder arranged outside the two oil pipelines. A baffle body is arranged inside the sealing cylinder. A sealing plate body is fixedly connected to the bottom of the sealing cylinder. A leakage detector is fixedly arranged on one side of the top of the sealing plate body. A fixed connecting plate is fixedly installed on the top of the baffle body. A sounding alarm is fixedly installed on the top of the fixed connecting plate. The cleaning mechanism includes a cleaning scraping ring arranged inside the sealing cylinder. A sliding rod body is fixedly connected to one side of the top of the cleaning scraping ring. A fixed clamping plate is fixedly connected to one side of the bottom of the baffle body. A fixed connecting rod is fixedly connected to the bottom of the fixed clamping plate. A cleaning plate body is fixedly connected to the bottom of the fixed connecting rod. Through the design of the cooperation of the leakage alarm mechanism and the cleaning mechanism, this invention application can not only detect the leakage of oil, but also scrape the oil adhering to the inner wall of the sealing cylinder, which is helpful to ensure the safety of oil production and transportation.

[0004] However, for marine oil products, which are a subdivision of biomass liquid fuel, most of them are diesel and heavy oil with high viscosity. In the initial stage of leakage at the flange, due to their high viscosity, they cannot flow out quickly from the flange joint, resulting in the leakage alarm mechanism being unable to detect it in the first place. Only when a large amount of marine oil products leaks can it be detected, leading to serious detection lag. In addition, since the leakage detection device is fixedly installed outside the pipeline flange, after detecting the oil leakage, the operator needs to remove it for maintenance, which increases the difficulty of subsequent inspection and maintenance. Therefore, in view of the above deficiencies of the existing pipeline leakage detection device for oil exploitation, this application proposes a safety production device for biomass liquid fuel that can effectively solve the above technical problems. Summary of the Invention

[0005] The object of the present invention is to provide a safety production device for biomass liquid fuel, so as to quickly detect the sealing state at the first time when there is a slight leakage at the pipeline flange connection of the oil pipeline, and remind the operators to repair and maintain in time to ensure the safety production of biomass liquid fuel.

[0006] The present invention is realized through the following technical solutions: A safety production device for biomass liquid fuel, including a track arranged parallel to the oil pipeline, a walking mechanism movably arranged on the track, and a detection mechanism for detecting the sealing performance of the pipeline flange connection arranged on the walking mechanism; The detection mechanism includes a frame plate fixedly connected to the walking mechanism. Two opening and closing semi-circular covers for sealing and clamping the conveying pipeline are symmetrically arranged on the frame plate. Inner arc strips are arranged on the inner circular walls of the opening and closing semi-circular covers. Air flow semi-circular grooves adapted to the pipeline flange are opened on the inner arc strips. After the two opening and closing semi-circular covers are closed, the two air flow semi-circular grooves form an air flow ring groove that completely seals the outer end of the pipeline flange. An inlet channel is opened on one of the opening and closing semi-circular covers. The inlet channel is tangentially connected to the air flow semi-circular groove. The outer end of the inlet channel is connected to a compressed air source fixed on the walking mechanism through a compressed air pipe. A discharge channel connected to the air flow semi-circular groove is opened on the other opening and closing semi-circular cover. And convex teeth are arranged on the inner groove wall of the air flow semi-circular groove close to the discharge channel. The outer end of the discharge channel is connected to a detection component fixed on the walking mechanism through a conveying pipe.

[0007] As a further setting of the above solution, the detection component includes a box body. A transparent deceleration pipe with one end connected to the conveying pipe is arranged inside the box body, and the other end of the transparent deceleration pipe extends out of the box body. An oil mist sensor arranged opposite to the transparent deceleration pipe is installed on the box body, and the oil mist sensor is electrically connected to a controller.

[0008] As a further setting of the above solution, the transparent deceleration pipe is arranged in a shape that is wide in the middle and narrow at both ends. The controller is connected to a remote terminal through a wireless transmission module.

[0009] As a further setting of the above solution, the detection mechanism further includes an outer shell body fixed on the frame plate. The two opening and closing semi-circular covers are symmetrically arranged in the outer shell body. A power device for driving the two opening and closing semi-circular covers to approach or move away from each other is arranged on the outer shell body. A chute guiding mechanism is arranged between the outer shell body and the opening and closing semi-circular covers.

[0010] As a further setting of the above solution, after the two opening and closing semi-circular covers are closed, the sector angle between the discharge channel and the inlet channel is set to be not less than 240°.

[0011] As a further setting of the above solution, a circular accommodation groove is formed on one side surface of the shelf plate. The detection mechanism further includes an outer shell body that is coaxially and rotatably arranged in the circular accommodation groove. A rotation driving assembly for driving the outer shell body to rotate is arranged on the shelf plate. Two opening and closing semi-cylindrical covers are symmetrically arranged in the outer shell body, and a chute guiding mechanism is arranged between the outer shell body and the opening and closing semi-cylindrical covers. The outer wall of each opening and closing semi-cylindrical cover is connected with a shaft rod that extends radially out of the outer shell body. A contact wheel is rotatably arranged at the outer end of the shaft rod. A spring with two ends respectively connected to the outer shell body and the opening and closing semi-cylindrical cover is sleeved on the shaft rod. Two inclined surface grooves that interact with the corresponding contact wheels are radially and outwardly formed on the circumferential side wall of the circular accommodation groove.

[0012] As a further setting of the above solution, the rotation driving assembly includes a rotation motor fixed on the shelf plate. A bevel gear is arranged on the motor shaft of the rotation motor. A bevel gear ring that meshes with the bevel gear is coaxially fixed on the end surface of the outer shell body.

[0013] As a further setting of the above solution, the compressed air source is a compressed air tank, and a solenoid valve for controlling the on-off of high-pressure air flow is arranged at the upper end of the compressed air tank.

[0014] As a further setting of the above solution, the traveling mechanism includes a carrier plate. A pair of traveling wheels that clamp the left and right sides of the track are rotatably arranged on the lower surface of the carrier plate. A power motor and a storage battery for driving the traveling wheels are arranged on the carrier plate.

[0015] As a further setting of the above solution, rotating bars are rotatably connected to the lower surface of the carrier plate on the front and rear sides of the traveling wheels through torsion springs. The ends of the two rotating bars are respectively provided with stabilizing wheels, and the two stabilizing wheels respectively act on the left and right side surfaces of the track.

[0016] During the operation of the biomass liquid fuel safety production equipment disclosed in the present invention, it can move at a fixed distance along the direction of the oil pipeline, and perform a sealing detection when moving to a position aligned with the pipeline flange.

[0017] In the specific detection process, two originally normally open opening and closing semi-cylindrical covers are closed, so that the two opening and closing semi-cylindrical covers can tightly seal the oil pipelines on both sides of the pipeline flange. At the same time, the two air flow semi-circular grooves are closed and completely seal the outer end of the pipeline flange, forming a complete air flow ring groove. Then, high-pressure air flow is continuously discharged through a compressed air source. The discharged high-pressure air flow enters the air flow ring groove along the tangential direction through the inlet channel, so that the high-speed air flow rotates and moves along the inner wall of the air flow ring groove to form a swirling flow. Due to the action of the swirling flow, the pressure on the side of the air flow ring groove close to the pipeline flange will drop sharply. At this time, once there is a slight leakage at the connection of the pipeline flange, oil will quickly leak out from it, and then be carried by the high-speed rotating air flow and move rapidly towards the discharge channel together. During its movement, it will impact on the convex teeth, causing the originally large oil droplets to be broken into a large number of small oil mists, and enter the transparent deceleration tube with the high-speed air flow to flow at a reduced speed, and finally can be quickly detected by the oil mist sensor.

[0018] In addition, the present invention also provides a total of two specific solutions for closing or opening the opening and closing semi-cylindrical covers. In the first solution, two opening and closing semi-cylindrical covers are directly pushed closer or farther away from each other by a linear pushing mechanism. However, the two closed opening and closing semi-cylindrical covers are fixed relative to the pipeline flange, and the high-pressure air flow cannot rotate 360°, resulting in a detection blind area in the sealed box. In the second solution, the two opening and closing semi-cylindrical covers are closed by adopting a rotation drive + abutting wheel extrusion and pushing method. After the detection is completed by introducing high-pressure air flow once, it can also rotate a certain angle for secondary detection, so that the secondary detection can cover the blind area of the primary detection, thereby realizing 360° dead-angle-free detection of the connection of the pipeline flange and improving the accuracy of detection.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The safety production equipment for biomass liquid fuel disclosed by the present invention changes the traditional principle of sealing detection for the connection of pipeline flanges. By setting two opening and closing semi-cylindrical covers to completely seal the outer end of the pipeline flange and forming a complete air flow ring groove, and then introducing high-pressure air flow into the air flow ring groove along the tangential direction, a high-speed rotating air flow is formed in the air flow ring groove. Under the action of the high-speed rotating air flow, the side of the air flow ring groove close to the pipeline flange will be in a negative pressure state, so that the oil that originally slowly dripped from the pipeline flange can be quickly extracted. After being extracted, it will impact on the convex teeth with the high-speed rotating air flow together to form oil mist, and finally be quickly detected by the oil mist sensor in the detection component. Compared with the existing detection devices, the detection mechanism in the present invention can more quickly detect whether there is a safety hazard of leakage at the pipeline flange, effectively avoiding the problem of detection lag when the existing detection devices are used to detect biomass liquid fuel with a relatively high viscosity. Its structural design is novel and ingenious, and the detection result is accurate and fast.

[0020] 2. The safety production equipment for biomass liquid fuel disclosed in the present invention can be moved along the track parallel to the conveying direction of the conveying pipeline by the traveling mechanism, and can be removed in time after the detection is completed, without hindering the operators from performing subsequent maintenance. Moreover, its moving setting can check the sealing of each pipeline flange on the entire section of the oil pipeline one by one, effectively ensuring the safety production of biomass liquid fuel such as ship oil products and having high safety.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1-9 , and will describe the present application in detail in combination with the embodiments. Embodiment 1

[0025] Embodiment 1 discloses a safety production device for biomass liquid fuel. Refer to the attached Figure 1 , including a track 200 arranged parallel to the oil pipeline 100. The lower end of the track 200 is fixed on the ground by a plurality of struts 201 arranged at equal intervals. A traveling mechanism 300 is arranged on the track 200, and a detection mechanism 400 for detecting the sealing performance of the connection of the pipeline flange 101 is arranged on the traveling mechanism 300, so that the detection mechanism 400 can move at a fixed distance under the action of the traveling mechanism 300, and then detect the sealing performance of each pipeline flange 101 on the entire oil pipeline 100 one by one.

[0026] Refer to the attached Figure 2 and the attached Figure 3 , the traveling mechanism 300 includes a carrier plate 301. A pair of traveling wheels 302 clamped on the left and right sides of the track 200 are rotatably arranged on the lower surface of the carrier plate 301, and a power motor 307 and a storage battery (not shown in the figure) for driving the traveling wheels 302 are arranged on the carrier plate 301. In addition, rotating bars 303 are rotatably connected to the lower surface of the carrier plate 301 on the front and rear sides of the traveling wheels 302 through torsion springs, and then stabilizing wheels 304 are arranged at the ends of the two rotating bars 303, and the two stabilizing wheels 304 act on the left and right sides of the track 200 respectively. When the traveling mechanism 300 moves to a turning point, the two stabilizing wheels 304 can be pressed against the two side surfaces of the track 200 through the action of the torsion springs and the rotating bars 303, and combined with the power input of the traveling wheels 302, the traveling mechanism 300 can move stably along the track 200. In addition, a vertical frame 305 is fixed on the upper surface of the carrier plate 301. A frame plate 306 is fixedly connected to one side surface of the vertical frame 305 facing the oil pipeline 100, and a circular hole with a diameter larger than that of the oil pipeline 100 and the pipeline flange 101 is opened at the center of the frame plate 306, so as to avoid being blocked during the movement of the frame plate 306.

[0027] Refer to the attached Figure 4 , the attached Figure 5 , the attached Figure 6 and the attached Figure 7, the detection mechanism 400 includes a housing 401 fixed on the shelf plate 306. Circular holes with apertures larger than those of the oil pipeline 100 and the pipeline flange 101 are also provided at the centers of both end faces of the housing 401. Vertical sliding grooves 4011 are provided at the upper and lower ends of the inner walls on both sides of the housing 401. Then, opening and closing semi-cylindrical covers 402 are arranged at the upper and lower ends of the housing 401, and sliders interacting with the corresponding vertical sliding grooves 4011 are provided on the outer side surfaces of the opening and closing semi-cylindrical covers 402. In addition, a power device (not shown in the figure) for driving the two opening and closing semi-cylindrical covers 402 to approach or move away from each other is also provided on the housing 401. The specific power device can be one of an electric push rod or a transmission mechanism of a lead screw + motor.

[0028] Semicircular openings with apertures consistent with the outer diameter of the oil pipeline 100 are provided at the centers of both end faces of the opening and closing semi-cylindrical cover 402, so that when the two opening and closing semi-cylindrical covers 402 are closed to form a complete circular cover, the oil pipelines 100 on both sides of the pipeline flange 101 can be tightly pressed and sealed. Inner arc strips 403 are provided on the inner circular walls of the opening and closing semi-cylindrical covers 402, and air flow semi-circular grooves 4031 adapted to the pipeline flange 101 are provided on the inner walls of the inner arc strips 403. After the two opening and closing semi-cylindrical covers 402 are closed, the two air flow semi-circular grooves 4031 form an air flow circular groove that completely seals the outer end of the pipeline flange 101 (refer to the appendix Figure 8 ). An inlet channel 4021 is provided on one of the opening and closing semi-cylindrical covers 402, and the inlet channel 4021 is arranged to be connected to the air flow semi-circular groove 4031 along the tangent direction thereof. An outlet channel 4022 connected to the air flow semi-circular groove 4031 is provided on the other opening and closing semi-cylindrical cover 402. The outlet channel 4022 can also be arranged along the tangent direction of the air flow semi-circular groove 4031, and the sector angle A between the outlet channel 4022 and the inlet channel 4021 is set to be not less than 240°, ensuring that when the high-pressure air flow enters from the outlet channel 4022 and exits from the inlet channel 4021, it can cover at least 2 / 3 of the area of the pipeline flange 101. In addition, convex teeth 4023 are provided on the inner groove wall of the air flow semi-circular groove 4031 on the side close to the outlet channel 4022.

[0029] A compressed air source 405 fixed on the vertical frame 305 is connected to the outer end of the inlet channel 4021 through a compressed air pipe 404. The compressed air source 405 is preferably a compressed air tank, and a solenoid valve is provided at its upper end to control the on-off of the high-pressure air flow. A delivery pipe 407 is connected to the outer end of the outlet channel 4022, and then a detection component connected to the delivery pipe 407 is provided on the upper surface of the carrier plate 301.

[0030] For the specific detection component, refer to the appendix Figure 9, which includes a box body 408 fixed on the upper surface of the carrier plate 301. Inside the box body 408, there is a transparent deceleration tube 406 with one end connected to the conveying pipe 407. The transparent deceleration tube 406 is designed in a shape that is wide in the middle and narrow at both ends, and the other end of the transparent deceleration tube 406 extends out of the box body 408. Through the action of the transparent deceleration tube 406, the introduced high-speed mixed air flow can be decelerated, facilitating subsequent detection. Finally, an oil mist sensor 409 based on the principle of light scattering is arranged on the box body 408 opposite to the middle section of the transparent deceleration tube 406. The oil mist sensor 409 is electrically connected to a controller (not shown in the figure). The controller can transmit the measured results to a remote terminal through a wireless transmission module. This wireless transmission part is prior art and will not be elaborated here.

[0031] During the operation of the biomass liquid fuel safety production equipment disclosed in Embodiment 1, the traveling mechanism 300 moves the detection mechanism 400 to the pipeline flange 101 to be detected, and then the power device makes the two openable semi-circular covers 402 approach each other, so that the two openable semi-circular covers 402 tightly press and seal the oil pipelines 100 on both sides of the pipeline flange 101. At the same time, the two air flow semi-circular grooves 4031 are closed and completely seal the outer end of the pipeline flange 101, forming a complete air flow ring groove.

[0032] Then the controller issues an instruction to make the compressed air source 405 continuously discharge high-pressure air flow. The discharged high-pressure air flow enters the air flow ring groove along the tangential direction through the inlet channel 4021 and forms a high-speed rotating air flow moving along the groove wall in the air flow ring groove, which will cause the pressure on the side of the air flow ring groove close to the pipeline flange to drop sharply. At this time, once there is a slight leakage in the pipeline flange 101, oil will quickly leak out from it (which can be understood as being sucked out), and together with the high-speed rotating air flow, it will quickly move towards the discharge channel 4022. Then, during its movement, it will hit the convex teeth 4023, so that the originally larger oil droplets are broken into a large number of small oil mists, and enter the transparent deceleration tube 406 with the high-speed air flow to flow after deceleration, and finally are quickly detected by the oil mist sensor 409, and the detected results will be timely transmitted to the remote terminal for corresponding personnel to view. When the operator arrives at the scene, the traveling mechanism 300 can move the detection mechanism 400 away from here, facilitating maintenance and repair. Embodiment 2

[0033] Embodiment 2 discloses a biomass liquid fuel safety production equipment that optimizes the design of the detection mechanism 400 based on the technical solution in Embodiment 1. The same parts as those in Embodiment 1 will not be described again.

[0034] Refer to the appendix Figures 2-5, the detection mechanism 400 in this Embodiment 2 includes a housing 401 fixed on the mounting plate 306. Circular holes with apertures larger than those of the oil pipeline 100 and the pipeline flange 101 are provided at the centers of both end faces of the housing 401. Vertical sliding grooves 4011 are provided at the upper and lower ends of the inner walls on both sides of the housing 401, and opening and closing semi-cylindrical covers 402 are provided at the upper and lower ends of the housing 401. Sliders interacting with the corresponding vertical sliding grooves 4011 are provided on the two outer side faces of the opening and closing semi-cylindrical covers 402.

[0035] A shaft rod 410 arranged radially is provided at the middle position of the outer walls of the two opening and closing semi-cylindrical covers 402. The top end of the shaft rod 419 extends out of the housing 401, and a contact wheel 411 is rotatably provided at the radially outer end of the shaft rod 410. Then, a spring 412 with its upper and lower ends respectively connected to the housing 401 and the opening and closing semi-cylindrical cover 402 is sleeved on the shaft rod 410. Under the action of the spring 412, the two opening and closing semi-cylindrical covers 402 can be in a normally open state, facilitating the unobstructed movement of the detection mechanism 400 along the oil pipeline 100.

[0036] In addition, in this Embodiment 2, the mounting plate 306 is circularly designed, and a circular accommodating groove 3061 for extending into the housing 401 is provided on one of its side faces. The housing 401 is concentrically and rotatably arranged in the circular accommodating groove 3061, and a corresponding rotation driving assembly is provided. Specifically, the rotation driving assembly includes a rotation motor 413 fixed on the mounting plate 306. A bevel gear 414 is provided on the motor shaft of the rotation motor 413, and then a bevel gear ring 415 meshing with the bevel gear 414 is concentrically fixed on the end face of the housing 401. Two inclined grooves 3062 interacting with the corresponding contact wheels 411 are radially provided outward on the circumferential side wall of the circular accommodating groove 3061, such that during the rotation of the housing 401, the contact wheel 411 can gradually transition from the inclined groove 3062 to abut against the circumferential side wall of the circular accommodating groove 3061, thereby overcoming the action of the spring 412 and causing the two opening and closing semi-cylindrical covers 402 to close together. In addition, the housing 401 can be continuously rotated to adjust the circumferential positions of the inlet channel 4021 and the outlet channel 4022 relative to the pipeline flange 101, so as to achieve a 360° all-round sealing detection of the pipeline flange 101.

[0037] Through the above structural design in this Embodiment 2, in the non-detection state, the contact wheel 411 extends into the inclined groove 3062, and under the action of the spring 412, the two opening and closing semi-cylindrical covers 402 can be in a normally open state, facilitating the unobstructed movement of the detection mechanism 400 along the oil pipeline 100.

[0038] When the detection mechanism 400 moves to a position aligned with the pipeline flange 101 for detection, the rotation motor 413 is started, and then the outer housing 401 is rotated under the meshing drive of the bevel gear 414 and the bevel gear ring 415. During the rotation of the outer housing 401, the abutting wheel 411 gradually transitions from the inclined groove 3062 to abut against the circumferential side wall of the circular accommodating groove 3061, thereby overcoming the action of the spring 412 and causing the two opening and closing semi-cylindrical covers 402 to close together. Then, the compressed air source 405 continuously discharges high-pressure air flow. The discharged high-pressure air flow enters the air flow ring groove along the tangential direction through the inlet passage 4021 and forms a high-speed rotating air flow that moves along the groove wall in the air flow ring groove, thereby causing the pressure on the side of the air flow ring groove close to the pipeline flange to drop sharply. At this time, once there is a slight leakage in the pipeline flange 101, oil will quickly leak out from it and move rapidly towards the discharge passage 4022 under the carrying of the high-speed rotating air flow. During its movement, it will hit the convex teeth 4023, causing the originally larger oil droplets to be broken into a large number of fine oil mists, and then enter the transparent deceleration tube 406 with the high-speed air flow to flow in a decelerated manner, and then be quickly detected by the oil mist sensor 409.

[0039] After the sealing detection of the sector angle area corresponding to the pipeline flange 101 is completed, continue to drive the outer housing 401 to rotate a certain angle so that the sector angle A between the discharge passage 4022 and the inlet passage 4021 at this time covers the sector angle area that was not detected in the pipeline flange 101 before, and then introduce high-pressure gas for the same test process. By combining the two detections before and after, a 360° full-round sealing detection of the pipeline flange 101 can be achieved, ensuring the accuracy of the detection result.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
