Description

Technical Field

[0001] The invention relates to the technical field of steam conveying pipelines, and in particular to a safety inspection device for steam temperature and pressure reduction pipelines of a gypsum board production line. Background Art

[0002] In a gypsum board production line, gypsum calcination and subsequent drying of gypsum boards require a large amount of mobile heat. Due to the high efficiency of high-temperature and high-pressure steam transmission, existing gypsum board production lines use high-temperature and high-pressure steam to provide heat energy for the above process.

[0003] Among them, high-pressure steam usually comes from power plant steam or steam produced by boilers burning in factories. When power plant steam or boilers burning in factories produce steam, the pressure and temperature of the steam are not stable. If the steam is used to produce and process gypsum boards, the steam with excessive pressure will not only damage the gypsum board production equipment, but also be detrimental to the calcination of gypsum and the drying of gypsum boards, resulting in a high defective rate of gypsum boards. Therefore, the steam pipeline used in the existing gypsum board production line is equipped with a cooling and pressure reducing device to control the temperature and pressure of the steam in the steam pipeline.

[0004] In the process of reducing temperature and pressure, various types of valves are installed on the steam pipeline, which increases the safety hazard of leakage compared with traditional straight pipe transmission. Therefore, the safety monitoring of the steam pipeline needs to be more rigorous. Only through the existing safety valves, pressure gauges, thermometers and other monitoring instruments, some small-scale pipeline leaks cannot be accurately detected. Most importantly, most of the above instruments can only play a warning role when a leak occurs, and cannot play a preventive inspection role. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In the existing steam pipelines with reduced temperature and pressure, only the existing safety valves, pressure gauges, thermometers and other monitoring instruments can not accurately detect some small-scale pipeline leaks. Most importantly, most of the above instruments can only play a warning role when a leak occurs, and cannot play a preventive inspection effect. Manual inspection is not only labor-intensive, but also cannot accurately detect some pipelines that bypass high places. Therefore, we propose the following solutions to solve the above problems:

[0043] like Figure 1 As shown, the present invention provides a safety inspection device for steam temperature and pressure reduction pipelines of a gypsum board production line, which has:

[0044] Track 2, track 2 is arranged parallel to the length direction of the steam delivery pipeline 1;

[0045] A monitoring and inspection component 4 is installed on the track 2, and the monitoring and inspection component 4 can move along the track 2;

[0046] The monitoring and inspection component 4 moves along the length direction of the track 2 to monitor and inspect the steam delivery pipeline 1 .

[0047] Specifically, when the safety inspection device is working, since the track 2 is set parallel to the steam transmission pipeline 1, when the monitoring inspection component 4 moves along the track 2, the monitoring inspection component 4 can automatically inspect the entire pipe section of the steam transmission pipeline 1 in real time, thereby eliminating the need for manual inspection, which not only reduces the labor intensity of workers but also increases the inspection speed. At the same time, for some bypass pipelines or high-level pipe sections, due to tool requirements (for example, manual inspection requires a ladder or a lifting platform), workers cannot conduct high-frequency inspections, which can also be overcome through the monitoring inspection component 4.

[0048] At the same time, the monitoring and inspection component 4 can reciprocate along the track 2, thereby realizing all-weather real-time inspection and monitoring of the steam transmission pipeline 1.

[0049] In order to conduct a more comprehensive and multi-angle inspection and monitoring of the steam transmission pipeline 1, refer to Figure 2 and Figure 1 As shown, in this embodiment: both ends of the steam delivery pipeline 1 are connected with elbows 101.

[0050] The track 2 includes two sections arranged on both sides of the steam conveying pipeline 1. When the monitoring and inspection components 4 move on the track 2 on both sides of the steam conveying pipeline 1, the two sides of the steam conveying pipeline 1 can be monitored and inspected.

[0051] Furthermore, the ends of the two sections of track 2 are connected in sequence through the semicircular track section around the elbow 101 to form a closed ring path, so that the two sides of the steam transmission pipeline 1 can be monitored and inspected by the same monitoring and inspection component 4.

[0052] In order to enable the monitoring and inspection component 4 to move on the track 2, in this embodiment: a patrol vehicle 3 is installed on the track 2, the patrol vehicle 3 can move along the length direction of the track 2, the monitoring and inspection component 4 is fixedly installed on the patrol vehicle 3, and the monitoring and inspection component 4 moves synchronously with the patrol vehicle 3.

[0053] Among them, inspection vehicles include remote-controlled cars and inspection robots.

[0054] In this embodiment, the information collected for monitoring and analyzing the steam delivery pipeline 1 includes images and noise. Since the steam inside the steam delivery pipeline 1 is high-pressure steam, when the steam delivery pipeline 1 leaks, obvious white mist and sharp noise will appear at the leak. Information is collected based on these two conditions and compared with the preset normal state to determine whether the steam delivery pipeline 1 is leaking. Figure 2 As shown, the specific implementation is as follows:

[0055] The monitoring and inspection component 4 includes a housing 401 connected to the inspection vehicle 3 , and an image collector 402 , a noise collector 403 , a signal transmitter and a vibration monitoring mechanism are arranged on the housing 401 .

[0056] Among them, the image collector 402 and the noise collector 403 are respectively used for photographing and monitoring the noise of the steam transmission pipeline 1 and transmitting them to the controller through the signal transmitter. The controller compares the information collected by the image collector 402 and the noise collector 403 with its preset monitoring information. If the controller determines that a steam leak occurs at the corresponding position of the steam transmission pipeline 1, the controller marks the position and sends a warning signal to the outside world, so that the inspection personnel can arrive at the corresponding position in time for maintenance.

[0057] When the high-temperature and high-pressure steam transmission pipeline 1 transports steam, water hammer will occur inside the steam transmission pipeline 1. The water hammer in the steam pipeline will cause the pipeline to vibrate, and then cause great damage to the steam transmission pipeline 1. The vibration of the steam transmission pipeline is a hidden danger that affects the safe operation of the equipment. Therefore, it is necessary to ensure the degree of vibration caused by the water hammer inside the steam transmission pipeline 1. Therefore, when monitoring and inspecting the steam transmission pipeline 1, the vibration of the surrounding wall of the steam transmission pipeline 1 is monitored by a vibration monitoring mechanism and transmitted to the controller through a signal transmitter, so as to determine whether water hammer occurs inside the steam transmission pipeline 1.

[0058] Reference Figure 1 As shown, in this embodiment: the vibration monitoring mechanism includes a driving member 404 and a vibration sensor 405 provided on the shell 1, the vibration sensor 405 is in sliding contact with the shell 1, and the vibration sensor 405 can move in a direction perpendicular to the steam delivery pipeline.

[0059] It also includes a conductive member arranged between the track 2 and the vibration sensor 405. The driving member 404 is fixedly installed on the shell 1 and is used to drive the vibration sensor 405 to move, so that the vibration sensor 405 presses the conductive member against the peripheral wall of the steam conveying pipeline 1. The conductive member is used to transmit the vibration at the peripheral wall of the steam conveying pipeline 1 to the probe of the vibration sensor 405.

[0060] A conductive member is provided at a pipe section of the steam conveying pipeline 1 where water hammer is prone to occur. When the monitoring and inspection component 4 moves to this section, the driving member 404 drives the vibration sensor 405 to move, so that the probe of the vibration sensor 405 abuts against one end of the conductive member, and the other end of the conductive member abuts against the peripheral wall of the steam conveying pipeline 1. When water hammer occurs in the steam conveying pipeline 1 and causes the steam conveying pipeline 1 to vibrate, the conductive member transmits the vibration to the probe of the vibration sensor 405. The vibration sensor 405 monitors the vibration at the peripheral wall of the steam conveying pipeline 1, thereby monitoring whether water hammer occurs at this point in the steam conveying pipeline 1 and the degree of vibration influence of the water hammer on the steam conveying pipeline 1.

[0061] The controller compares the vibration signal with its preset vibration signal. If the vibration signal exceeds its preset threshold, the controller marks the position of the steam delivery pipeline 1 so that the inspection personnel can reach the corresponding position in time for maintenance.

[0062] In this embodiment, the conductive member includes a fixed plate 5 connected to the track 2, a sleeve 6 is fixedly inserted on the fixed plate 5, a stopper 7 is inserted in the sleeve 6, and the stopper 7 is in sliding contact with the sleeve 6.

[0063] The driving component 404 includes a linear motor, and an output end of the linear motor is connected to one end of the vibration sensor 405 .

[0064] When the monitoring and inspection component 4 moves on the track 2, the image acquisition device 402 first identifies the position of the conductive part, and then the monitoring and inspection component 4 stops moving, and makes the probe of the vibration sensor 405 face the abutment rod 7. Then, the linear motor is started, and the linear motor drives the vibration sensor 405 to move, and the probe of the vibration sensor 405 abuts against one end of the abutment rod 7, and makes the abutment rod 7 move so that its other end abuts against the peripheral wall of the steam conveying pipeline 1.

[0065] Since the existing steam delivery pipeline 1 is provided with a thermal insulation layer and a protective layer on the outside, when the abutment rod 104 abuts against the outer wall of the steam delivery pipeline 1, the vibration of the inner wall of the steam delivery pipeline 1 will be reduced by the thermal insulation layer and the protective layer, resulting in that the internal vibration of the steam delivery pipeline 1 cannot be accurately transmitted to the vibration sensor 405 through the transmission element, thereby reducing the accuracy of the vibration sensor 405 monitoring. For this reason, referring to Figure 4 As shown, in this embodiment:

[0066] The steam conveying pipeline 1 comprises, from the inside to the outside, an inner tube 101, a thermal insulation layer 102 and a protective layer 103. A needle rod 104 is connected to the peripheral wall of the inner tube 101. The other end of the needle rod 104 extends to the outside of the protective layer 103 and faces the abutment 7. Both the needle rod 104 and the abutment 7 are made of metal with good vibration conduction. The vibration inside the steam conveying pipeline 1 is directly contacted with the conduction component through the needle rod 104, thereby improving the vibration conduction efficiency on the steam conveying pipeline 1.

[0067] The intermittent vibration of the steam delivery pipeline 1 and the looseness of the support bracket will cause the steam delivery pipeline 1 to gradually deviate, which is difficult to directly identify with the human eye. Figure 1 As shown, in this embodiment:

[0068] A positioning groove 8 is provided on the end surface of the push rod 7 facing the needle rod 104, a retaining ring 9 is fixedly sleeved on the push rod 7, and a spring 10 is connected between the retaining ring 9 and the sleeve 6. When the monitoring and inspection component 4 does not reach the conductive part, under the elastic force of the spring 10, the push rod 7 moves away from the needle rod 104, and the positioning groove 8 is separated from the needle rod 104. When the monitoring and inspection component 4 reaches the conductive part, the driving member 404 drives the vibration sensor 405 to move, and the vibration sensor 405 The push rod 7 is driven to move toward the needle rod 104 and compress the spring 10 until the needle rod 104 is inserted into the positioning groove 8, thereby completing the connection between the needle rod 104 and the push rod 7. The vibration on the steam delivery pipeline 1 is transmitted to the probe of the vibration sensor 405 through the needle rod 104 and the push rod 7. When the monitoring inspection component 4 leaves the transmission part, under the elastic force of the spring 10, the push rod 7 moves away from the needle rod 104, so that the needle rod 104 and the push rod 7 are separated again, and this cycle repeats.

[0069] Since the needle rod 104 is connected to the steam conveying pipe 1, when the steam conveying pipe 1 is offset, the steam conveying pipe 1 will also affect the angle between the needle rod 104 and the push rod 7 until the offset of the steam conveying pipe 1 is greater than the set value. When the push rod 7 approaches the needle rod 104, the needle rod 104 is misaligned with the positioning groove 8, and the needle rod 104 cannot be connected to the push rod 7. Without the conduction of the needle rod 104, the vibration sensor 405 monitors the vibration of the steam conveying pipe 1. The obtained vibration monitoring data is significantly different from the preset value. The controller can promptly send a warning signal to the outside world, thereby checking the corresponding pipe section position of the steam conveying pipe 1, thereby eliminating the safety risk of the steam conveying pipe 1 and increasing the function of the monitoring and inspection component 4 to monitor and inspect the steam conveying pipe 1.

[0070] A safety inspection method for steam temperature and pressure reduction pipelines of a gypsum board production line comprises the following steps:

[0071] S100, setting a specific vibration monitoring area according to the characteristics of the steam delivery pipeline 1;

[0072] S200, start the inspection vehicle 3 to move along the track 2, and start the monitoring inspection component 4 to monitor the external environment of the entire section of the steam delivery pipeline 1, and when the inspection vehicle 3 moves in a circular motion on the track 2, the controller compares the monitoring information on both sides of the steam delivery pipeline 1 through the monitoring inspection component 4;

[0073] S300, the monitoring conditions of the monitoring inspection component 4 include whether there is white mist and sharp noise generated by visual steam leakage, and the controller compares the monitoring information obtained by the monitoring inspection component 4 with the preset monitoring information therein to analyze whether steam leakage occurs at the corresponding monitoring position of the steam transmission pipeline 1;

[0074] S400 , the inspection vehicle 3 stops moving when it moves to a specific vibration monitoring area, and starts a vibration monitoring mechanism to perform vibration monitoring on the steam delivery pipeline 1 .
