Description

Technical Field

[0001] The invention belongs to the technical field of water vapor monitoring, and in particular relates to a signal transmission calling system for boiler water vapor monitoring. Background Art

[0002] Boilers are widely used in various fields such as power plants. Boiler users should regularly test and analyze the water vapor quality in order to analyze and judge the overall working condition of the boiler. This requires the collection of water vapor during the use of the boiler. The general method is to directly collect the boiler water produced by the boiler for testing and analysis. The main test indicators include conductivity, pH value, ammonia nitrogen and total nitrogen.

[0003] In the prior art, boiler cooling water is generally collected directly from the condensate pool, and then the collected boiler cooling water is transported to the detection equipment to complete the detection and analysis of various indicators. In order to more directly and accurately reflect the quality of boiler water vapor, it is necessary to collect cooling water for detection at regular intervals. The collected cooling water all comes from the condensate pool.

[0004] However, the above boiler water vapor monitoring process cannot realize the mutual linkage between boiler monitoring and water vapor detection, resulting in the boiler pressure relief process and the boiler water vapor detection process being completely independent, and directly collecting cooling water from the condensate pool easily leads to low accuracy of detection data, and it is impossible to realize the water vapor detection process in the process of completing the boiler water vapor pressure early warning control through the joint application of multiple sensors, which is not conducive to real-time feedback of the boiler's operating status. To this end, we provide a signal transmission call system for boiler water vapor monitoring to solve the above problems. Summary of the invention

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention uses the action of boiler water vapor to make the trigger part press against the third pressure sensor. When the pressure value monitored by the third pressure sensor reaches the set high pressure value, the controller receives the pressure signal and controls the first alarm to sound an alarm. The control terminal receives the alarm signal and sends a pressure relief command to the controller. The reverse push rod is driven to push the trigger part by the rotation of the missing gear. When the trigger part is separated from the radial mounting groove, the radial pressure relief groove is aligned with the trigger part by the pushing action of the switching pusher on the closed pressure relief mechanism. The movable pressure relief pipe is controlled to move to achieve plug-in connection with the collection and conveying component. The water vapor released from the pressure relief is discharged into the collection and conveying component through the water vapor pressure relief hole to achieve condensation. When the pressure value monitored by the third pressure sensor reaches the set low pressure value, the controller receives the pressure signal and controls the first alarm to sound an alarm again. The control terminal receives the alarm signal and sends a blocking command to the controller. The radial mounting groove is aligned with the trigger part by the reverse rotation of the switching pusher. The trigger part is reinserted into the radial mounting groove to achieve blocking of the water vapor pressure relief hole, thereby achieving automatic control of boiler water vapor monitoring.

[0019] 2. In the present invention, when the movable pressure relief pipe moves to align with the water vapor diversion pipe, the electromagnet is energized to generate magnetic repulsion force on the magnetic ring, so that the magnetic ring slides along the fixed pressure relief pipe, and the first moving rod that moves synchronously with the magnetic ring drives the second elastic member to be stretched, thereby driving the movable pressure relief pipe to move along the fixed pressure relief pipe toward the axial direction of the monitoring bearing ring until the driving shaft on the opening and closing control ball slides into the inside of the introduction channel and fits on the inner end of the introduction channel. At this time, one end of the movable pressure relief pipe is horizontally inserted into the water vapor input pipe, and the axial sealing strip just fits in the inside of the introduction channel. The support ring It just presses tightly against the end of the water vapor input pipe, and the magnetic ring presses against the fourth pressure sensor on the ear seat, and then the second meshing part is driven to slide along the second guide rod through the telescopic cylinder, and the opening and closing gear is driven to rotate 90° under the action of the second meshing part. At this time, the opening and closing control ball releases the blockage of the open end of the movable pressure relief pipe, and then the water vapor in the water vapor diversion pipe enters the fixed pressure relief pipe through the radial pressure relief groove, and then enters the water vapor input pipe through the movable pressure relief pipe, and finally flows upward from the liquid storage tube into the spiral condenser tube for condensation, and the generated condensed water flows back to the liquid storage tube along the spiral condenser tube for storage.

[0020] 3. In the process of controlling the missing gear to rotate clockwise, the lifting gear that rotates synchronously with the missing gear drives the third meshing part to move upward, and the vertical blocking rod is driven to slide upward along the first delivery pipe through the upwardly moved third meshing part. During the pressure relief process, the first delivery pipe can be blocked by the vertical blocking rod, so that the liquid storage tube and the second delivery pipe are in an isolated state. After the pressure relief is completed, the entire closed pressure relief mechanism is controlled to rotate counterclockwise back to the initial position. At this time, the upper end of the vertical blocking rod moves down again to a position close to the bottom of the second delivery pipe. Subsequently, the condensed water in the liquid storage tube passes through the first delivery pipe and the second delivery pipe in turn and flows into the third delivery pipe, and then flows into various detection devices through various detection connectors for detection. In this way, the automatic real-time collection and detection of condensed water is achieved during the pressure relief process, thereby improving the accuracy of boiler water vapor detection.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The movable pressure relief pipe 304 is inserted horizontally into the water vapor input pipe 415, and the axial sealing strip 321 is just loosely fitted in the introduction channel 416. The support ring 320 is just tightly pressed against the end of the water vapor input pipe 415, and the magnetic ring 315 is pressed against the fourth pressure sensor on the ear seat. Then, the second meshing portion 414 is driven along the second guide rod 414 by the telescopic cylinder 413. 2 slides, and under the action of the second meshing portion 414, the on-off gear 323 is driven to rotate 90°. At this time, the on-off control ball 322 releases the blockage of the open end of the movable pressure relief pipe 304, and then the water vapor in the water vapor guide pipe 203 enters the fixed pressure relief pipe 314 through the radial pressure relief groove 302, and then enters the water vapor input pipe 415 from the movable pressure relief pipe 304, and finally flows upward from the liquid storage cylinder 408 into the spiral condensation pipe 410 for condensation, and the generated condensed water flows back to the liquid storage cylinder 408 along the spiral condensation pipe 410 for storage.

[0050] In this embodiment of the present invention, a moving plate 417 slidably sleeved on the first guide rod 109 is fixedly provided at the other end of the first meshing portion 404, and a second moving rod 418 slidably matched with the monitoring carrier ring 101 is fixedly provided on one side of the moving plate 417. The connecting disk fixed at the end of the second moving rod 418 is connected to the monitoring carrier ring 101 through a third elastic member 419. The third elastic member 419 is in a natural state in the initial state, and the reverse thrust rod 405 is horizontally inserted into the penetration port 207 on the hollow mounting portion 204 and fits with the piston plate 205. The trigger portion 201 fits inside the radial mounting groove 301, and the orifice sealing plug 3 11 is inserted into the corresponding water vapor pressure relief hole 202, so that the water vapor pressure relief holes 202 on the trigger part 201 are blocked, and a first delivery pipe 420 connected to the bottom of the liquid storage cylinder 408 is fixedly provided, and a second delivery pipe 421 is connected to the side surface of the first delivery pipe 420, and a third delivery pipe 422 connected to the second delivery pipe 421 is fixedly provided at one end, and a plurality of detection connectors 423 are installed on the side surface of the third delivery pipe 422. By setting a plurality of detection connectors 423, each detection connector 423 can be connected to different detection devices through a hose, so that the detection of different components in water vapor can be realized at the same time.

[0051] In this embodiment of the present invention, a third meshing portion 424 is slidably provided on the inner wall of the monitoring support frame 105, a lifting gear 425 meshing with the third meshing portion 424 is fixedly installed on the side surface of the power output shaft 401, and a vertical blocking rod 426 is slidably provided inside the first conveying pipe 420, and the vertical blocking rod 426 is fixedly connected to the third meshing portion 424. The position of the vertical blocking rod 426 in the initial state is as shown in FIG. Fig.13 As shown, the upper end of the vertical blocking rod 426 is close to the bottom of the second delivery pipe 421. In the process of controlling the missing gear 402 to rotate clockwise, the lifting gear 425 that rotates synchronously with the missing gear 402 drives the third meshing portion 424 to move upward, and the vertical blocking rod 426 is driven to slide upward along the first delivery pipe 420 through the upwardly moved third meshing portion 424. In the process of depressurization, the first delivery pipe 420 can be blocked by the vertical blocking rod 426, so that the liquid storage cylinder 408 and the second delivery pipe 421 are in an isolated state. After the pressure relief, the entire closed pressure relief mechanism 3 is controlled to rotate counterclockwise back to the initial position. At this time, the upper end of the vertical blocking rod 426 moves down again to a position close to the bottom of the second delivery pipe 421, and then the condensed water in the liquid storage cylinder 408 passes through the first delivery pipe 420 and the second delivery pipe 421 in turn and flows into the third delivery pipe 422, and then flows into various detection devices through various detection connectors 423 for detection, thereby realizing automatic real-time collection and detection of condensed water during the pressure relief process, thereby improving the accuracy of boiler water vapor detection.

[0052] The specific working process of the present application is as follows: when the pressure value monitored by the third pressure sensor 303 reaches the set high pressure value, the controller receives the pressure signal and controls the first alarm to sound an alarm, the control terminal receives the alarm signal and sends a pressure relief instruction to the controller, and the controller controls the power motor to start and drive the power output shaft 401 to rotate clockwise (such as Figure 2As shown in the figure, the first meshing portion 404 is driven to move to the left side by the rotation of the missing gear 402 and the third elastic member 419 is compressed. In this process, the piston plate 205 is pushed by the reverse push rod 405 to compress the first elastic member 206. The triggering portion 201 that moves synchronously with the piston plate 205 gradually moves to the outside of the radial mounting groove 301. When the triggering portion 201 just leaves the radial mounting groove 301, the switching pusher 403 that rotates clockwise just fits the top of the second arc-shaped channel 305. As the missing gear 402 continues to rotate clockwise, the triggering portion 201 continues to move and compress the first elastic member 206. Under the thrust of the switching pusher 403, the entire closed pressure relief mechanism 3 continues to rotate clockwise, so that the radial mounting groove 301 is opened. 01 is misaligned with the trigger part 201. When the missing gear 402 is disengaged from the first meshing part 404, the elastic restoring force of the first elastic member 206 makes the trigger part 201 tightly abut against the outer wall of the arc-shaped blocking plate 306, and the elastic restoring force of the third elastic member 419 makes the first meshing part 404 move to the right to complete the reset. When the missing gear 402 is meshed with the first meshing part 404 again, it continues to drive the first meshing part 404 to move to the left and compress the third elastic member 419. During this process, the movement of the reverse push rod 405 does not continue to push the piston plate 205 (that is, the reciprocating motion of the reverse push rod 405 at this time does not contact the piston plate 205). When the radial pressure relief groove 302 is aligned with the trigger part 201 (the water vapor pressure relief hole 202 is located on the inner side of the radial pressure relief groove 302, and the trigger part 201 still rests on the outer wall of the arc-shaped blocking plate 306), the second pressure sensor 104 monitors the pressure signal and sends the pressure signal to the controller, the controller controls the second alarm to sound an alarm, the control terminal receives the alarm signal and sends a command to the controller, at this time the controller controls the electromagnet 316 to be energized to generate a magnetic repulsive force on the magnetic ring 315, until the driving shaft on the open and close control ball 322 slides into the inside of the introduction channel 416 and fits on the inner end of the introduction channel 416, at this time, one end of the movable pressure relief pipe 304 is horizontally inserted into the water vapor input pipe 415, the axial sealing strip 321 just fits in the introduction channel 416 with a gap, and the support ring 320 just presses tightly At the end of the water vapor input pipe 415, the magnetic ring 315 is pressed against the fourth pressure sensor on the ear seat. The fourth pressure sensor detects the pressure signal and sends the pressure signal to the controller. The controller controls the third alarm to sound an alarm. The control terminal receives the alarm signal and sends a command to the controller. At this time, the controller controls the telescopic cylinder 413 to start, and drives the second meshing part 414 to slide along the second guide rod 412 through the telescopic cylinder 413. Under the action of the second meshing part 414, the opening and closing gear 323 is driven to rotate 90°. At this time, the opening and closing control ball 322 releases the blockage of the open end of the movable pressure relief pipe 304, and then the water vapor entering the water vapor guide pipe 203 from the boiler enters the radial pressure relief groove 302 through the water vapor pressure relief hole 202.Then it enters the fixed pressure relief pipe 314 through the radial pressure relief groove 302, and then enters the water vapor input pipe 415 through the movable pressure relief pipe 304, and finally flows upward from the liquid storage cylinder 408 into the spiral condensation pipe 410 for condensation. The generated condensed water flows back to the liquid storage cylinder 408 along the spiral condensation pipe 410 for storage;

[0053] When the pressure value monitored by the third pressure sensor 303 reaches the set low pressure value, the controller receives the pressure signal and controls the first alarm to sound the alarm again. The control terminal receives the alarm signal and sends a blocking instruction to the controller. The controller controls the telescopic cylinder 413 to start again, and drives the second meshing part 414 to complete the reset through the telescopic cylinder 413. Under the action of the second meshing part 414, the through-and-close gear 323 is driven to rotate 90° in the opposite direction. At this time, the through-and-close control ball 322 blocks the open end of the movable pressure relief pipe 304 again (the second meshing part 414 and the through-and-close gear 323 are in a separated state). Then the controller controls the electromagnet 316 to cut off the power and demagnetize to release the magnetic repulsive force on the magnetic ring 315, so that the movable pressure relief pipe 304 is separated from the water vapor input pipe 415 and returns to the initial position. Then the controller controls the power motor to run in the reverse direction to make the power output shaft 401 rotate counterclockwise. During the counterclockwise rotation of the switching pusher 403, the entire closed The pressure relief mechanism 3 gradually slides downward along the second arc-shaped channel 305 under the action of its own gravity until the closed pressure relief mechanism 3 returns to the initial position, that is, the radial mounting groove 301 is realigned with the trigger part 201, and the trigger part 201 is reinserted into the radial mounting groove 301 under the action of the elastic restoring force of the first elastic member 206, and the trigger part 201 is reinserted into the radial mounting groove 301 to achieve the sealing of the water vapor pressure relief hole 202. At this time, the orifice sealing plug 311 is reinserted into the corresponding water vapor pressure relief hole 202, so that the sealing of each water vapor pressure relief hole 202 on the trigger part 201 is achieved again. At this time, the first pressure sensor 103 monitors the pressure from the extension trigger plate 312, and the controller receives the pressure signal and controls the fourth alarm to sound an alarm. The control terminal receives the alarm signal and sends an instruction to the controller, and the controller controls the power motor to stop running. In this way, the above-mentioned control process can be used to achieve automatic control during the use of the boiler.
