Description

Technical Field

[0001] This utility model relates to the field of pipeline drainage technology, and in particular to an automatic drainage device for boiler steam pipelines. Background Technology

[0002] Steam pipelines are used in systems that use steam as a power source or heat medium. They are responsible for safely and efficiently transporting the high-temperature, high-pressure steam generated by the boiler to various steam-using equipment. When the steam flows in the pipeline, due to the high temperature of the steam and the large temperature difference with the external environment, heat is inevitably lost to the outside. This causes some of the steam to condense into liquid water, i.e., condensate. In order to discharge the condensate, an automatic condensate discharge device for boiler steam pipelines is required.

[0003] Traditional steam pipe condensate traps consist of a condensate valve, a collection tank, and a drainage pipe. When condensate is generated in the steam pipe, it collects in the collection tank under gravity. The collection tank is connected to the condensate valve, which senses the arrival of condensate and opens the valve to allow the condensate to be discharged out of the system through the drainage pipe. However, traditional condensate traps lack a preliminary purification function for the condensate, which can lead to pipe blockage. Current technology uses filters for filtration, but in actual use, the complex and variable operating conditions inside the steam pipe, with rapidly changing temperature and pressure parameters, cause a certain lag in the data collected by the sensors. This makes it impossible to adjust the opening of the condensate valve in time, resulting in steam leakage or water hammer, which reduces the practicality of the device. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an automatic steam pipe drainage device for boilers, comprising a steam pipe 1 for transporting steam generated by the boiler to various steam-using parts to ensure a continuous thermal flow. A steam inlet pipe 3 is connected to the top right side of the steam pipe 1, guiding the steam flow to subsequent processing components and providing a channel for preliminary steam treatment. A spiral guide vane 4 is fixedly connected to the inner wall of the steam inlet pipe 3, causing the steam to rotate and separating condensate from the steam using centrifugal force. Simultaneously, the steam flow washes the pipe wall, reducing dirt adhesion. A condensate collection chamber 5 is connected to the right end of the steam inlet pipe 3, collecting the condensate flowing in from the steam inlet pipe 3 and providing storage space for drainage treatment. The top of the condensate collection chamber 5 is equipped with... A sealing plate 6 and a sealing gasket 17 seal the top opening of the condensate collection chamber 5 to prevent steam leakage and ensure the sealing and safety of the device. A drain pipe 7 connects to the bottom of the condensate collection chamber 5, serving as the outlet for the treated condensate. A control valve 8 is fixedly connected to the outer wall of the drain pipe 7, regulating the opening and closing of the drain pipe 7 and the drainage flow rate according to control system commands to ensure stable drainage. A filter frame 9 is slidably connected to the left side of the inner wall of the condensate collection chamber 5, filtering out fine impurities during condensate sedimentation to prevent blockage of downstream pipes. A float rod 10 is slidably connected to the inner wall of the condensate collection chamber 5, rising and falling with the condensate level. A float ball 11 is fixedly connected to the bottom of the float rod 10. The float 11 uses buoyancy to drive the float rod 10, reflecting changes in liquid level. A connecting plate 12 is fixedly connected to the top of the float rod 10, and a tactile switch 13 is installed on the connecting plate 12. Tactile switches 13 are also fixedly connected to the upper and lower sides of the right end of the outer wall of the connecting plate 12. The tactile switches 13 cooperate with the limiting plate 14, triggering when the liquid level reaches a specific height, sending a signal to the control system to start or stop the drainage operation, thus achieving liquid level control. Limiting plates 14 are fixedly connected to the upper and lower sides of the right end of the inner wall of the condensate collection chamber 5. The limiting plates 14 provide trigger positions for the tactile switches 13, limiting the travel of the float rod 10 and float 11, ensuring the accuracy of liquid level monitoring and control. A liquid level sensor 15 is fixedly connected to the top of the rear side of the inner wall of the condensate collection chamber 5, monitoring... The condensate level height is transmitted to the control system, forming redundant monitoring with the tactile switch 13, providing data support for accurate drainage. A coarse filter 16 is fixedly connected to the right side of the inner wall of the steam inlet pipe 3. The coarse filter 16 intercepts larger rust particles in the steam, preventing them from entering the condensate collection chamber 5 and causing blockage of internal components, thus protecting the internal structure of the device. A sealing gasket 17 is fixedly connected to the top of the condensate collection chamber 5. The sealing gasket 17 fits against the sealing plate 6, filling gaps, enhancing sealing performance, and eliminating the risk of steam leakage. A quick-installation mechanism 2 is provided at the bottom of the sealing plate 6. The quick-installation mechanism 2 is used for quick disassembly and assembly of the sealing plate 6. During equipment maintenance and repair, operators can easily disassemble or install the sealing plate 6 with its help, shortening downtime and improving equipment maintenance efficiency.

[0032] Specifically, when the steam system starts, high-temperature and high-pressure steam flows from steam pipe 1 into steam inlet pipe 3. The spiral guide vane 4 causes the steam to rotate at high speed. Under the action of centrifugal force, the condensate in the steam is thrown towards the pipe wall, initially separating from the steam. At the same time, the steam flow washes the pipe wall to reduce dirt. The mixture of steam and condensate then passes through the coarse filter screen 16, which intercepts larger particles of impurities such as rust and silt. The purified mixture enters the condensate collection chamber 5. Under the action of gravity, the condensate settles at the bottom of the condensate collection chamber 5. As the liquid level rises, the float ball 11 drives the float rod 10 to float. When the liquid level reaches a certain height, the top of the float rod 10 connects to the top plate 12. When the tactile switch 13 touches the top limit plate 14, it immediately sends a signal to the control switch. The control switch quickly opens the control valve 8, and the condensate is discharged through the drain pipe 7. During the liquid level drop, when the bottom tactile switch 13 touches the bottom limit plate 14, it sends a signal again, and the control switch closes the control valve 8 to stop the drainage. The liquid level sensor 15 monitors the liquid level in real time and transmits the data to the control system, forming redundant monitoring with the tactile switch 13. This ensures that when the steam conditions are complex and changeable, the control system can adjust the opening of the control valve 8 in a timely and accurate manner according to the liquid level, avoiding steam leakage or water hammer.

[0033] Reference Figure 1 , Figure 3 and Figure 5The quick-installation mechanism 2 includes multiple insert plates 201, which are fixedly connected to the bottom left and right sides of the sealing plate 6, providing a foundation for subsequent connection with the condensate collection chamber 5. Two slots 202 are provided on the top left and right sides of the condensate collection chamber 5, with the slots 202 being sized to fit the insert plates 201. The multiple insert plates 201 are slidably connected to their corresponding slots 202, allowing the sealing plate 6 to slide smoothly along the slots 202 during installation, achieving initial fixation while ensuring a tight connection and effectively preventing steam leakage. Sliding grooves 203 are provided on the left and right sides of the outer wall of the condensate collection chamber 5, providing guidance for the movement of subsequent components. Connecting rods 204 are slidably connected to the inner walls of the two sliding grooves 203, allowing them to slide freely back and forth within the path defined by the sliding grooves 203, thus flexibly controlling the locking block 205. Position, the top front and rear sides of the two connecting rods 204 are fixedly connected with locking blocks 205, which are used to cooperate with the slots 209 on the insert plate 201 to lock the insert plate 201. The middle of the outer wall of the two connecting rods 204 is fixedly connected with limit blocks 206 to limit the sliding range of the connecting rods 204 and prevent them from excessive displacement and leaving the track. The front end of the two limit blocks 206 is fixedly connected with springs 207 to ensure that the locking blocks 205 can tightly lock the slots 209 under normal conditions. The front end of the two springs 207 is fixedly connected with the corresponding sliding grooves 203. The front end of the two connecting rods 204 passes through the condensate collection chamber 5 and is fixedly connected with the same connecting plate 208. The middle of the multiple insert plates 201 is provided with slots 209, and the multiple locking blocks 205 are respectively engaged with the corresponding slots 209.

[0034] Specifically, when maintenance is required on the internal components of the condensate collection chamber 5, the operator manually pulls the connecting plate 208, causing the connecting rod 204 to slide forward in the sliding groove 203. The locking block 205 disengages from the slot 209 of the insert plate 201, releasing the restriction on the insert plate 201. The operator then gently lifts the sealing plate 6, and the insert plate 201 is smoothly pulled out along the slot 202, achieving rapid separation of the sealing plate 6 from the condensate collection chamber 5, facilitating operation of the internal components. After maintenance, the operator first aligns the insert plate 201 with the slot 202, presses down the sealing plate 6 to fully insert the insert plate 201, releases the connecting plate 208, and under the elastic force of the spring 207, the connecting rod 204 slides backward to reset, and the locking block 205 re-engages into the slot 209, firmly fixing the sealing plate 6, completing the reinstallation.

[0035] Reference Figure 1 , Figure 2 and Figure 4A steam diversion pipe 18 is connected to the left side of the outer wall of the steam inlet pipe 3, and a regulating valve 19 is fixedly connected to the outer wall of the steam diversion pipe 18; a pressure balancing pipe 20 is connected to the front side of the outer wall of the condensate collection chamber 5, the left end of the pressure balancing pipe 20 is connected to the steam pipe 1, and a one-way valve 21 is fixedly connected to the outer wall of the pressure balancing pipe 20; an observation frame 22 is fixedly connected to the front side of the outer wall of the condensate collection chamber 5, and a transparent plate 23 is fixedly connected to the inner wall of the observation frame 22.

[0036] Specifically, when the steam flow and pressure are unstable, the regulating valve 19 can be adjusted to divert some of the steam through the steam diversion pipe 18 and stabilize the steam state entering the condensate collection chamber 5. The pressure balancing pipe 20 and the one-way valve 21 can balance the pressure between the condensate collection chamber 5 and the steam pipe 1 to prevent pressure difference from damaging the equipment. The observation frame 22 and the transparent plate 23 facilitate real-time monitoring of the condensate level and other conditions in the chamber, ensuring safe operation.

[0037] Reference Figure 1 , Figure 2 and Figure 5 A temperature detector 24 is fixedly connected to the right side of the outer wall of the condensate collection chamber 5. A probe 25 is fixedly connected to the left end of the temperature detector 24. The temperature detector 24 on the outer wall of the condensate collection chamber 5 senses the temperature of the condensate in the chamber in real time through the probe 25 and transmits the data to the control system to assist in judging the steam condensation situation. The left end of the probe 25 penetrates through the condensate collection chamber 5. An information plate 26 is set at the bottom front side of the outer wall of the condensate collection chamber 5 to mark the equipment parameters for easy viewing by operation and maintenance personnel. Screws 27 are threadedly connected at the four corners of the outer wall of the information plate 26. The rear ends of the multiple screws 27 are threadedly connected to the condensate collection chamber 5. A handle 28 is fixedly connected to the front side of the outer wall of the connecting plate 208. The surface of the handle 28 is treated with anti-slip treatment. When it is necessary to operate the quick-installation mechanism 2, the operator holds the anti-slip handle 28 and pulls the connecting plate 208, which saves effort and is not easy to slip, ensuring quick disassembly and assembly of the sealing plate 6.

[0038] Specifically, the temperature detector 24 on the outer wall of the condensate collection chamber 5 senses the temperature of the condensate in the chamber in real time through the probe 25, transmits the data to the control system, and assists in judging the steam condensation situation for precise control. The information plate 26 is fixed to the bottom of the front side with screws 27, which can mark the equipment parameters for easy viewing by maintenance personnel. When the quick-installation mechanism 2 needs to be operated, the operator holds the non-slip handle 28 and pulls the connecting plate 208, which is labor-saving and not easy to slip, ensuring quick disassembly and assembly of the sealing plate 6.

[0039] Working Principle: High-temperature steam enters the steam inlet pipe 3 from the steam pipe 1. The spiral guide vanes 4 inside the steam inlet pipe 3 cause the steam to rotate and flow. This rotation utilizes centrifugal force to throw the condensate in the steam towards the pipe wall, facilitating the initial separation of condensate. It also has a certain flushing effect on the pipe wall, reducing dirt adhesion. The steam and condensate mixture passes through the coarse filter 16, which intercepts larger particles of impurities, preventing them from entering the condensate collection chamber 5 and causing blockage. Subsequently, the mixture enters the condensate collection chamber 5, where the condensate gradually settles to the bottom under gravity. As the condensate accumulates, the float 11, due to buoyancy, causes the float rod 10 to rise. When the condensate level rises to a certain height, the top of the float rod 10 connects to the plate 12. When the top tactile switch 13 touches the top limit plate 14, the tactile switch 13 sends a signal to the control switch. After receiving the signal, the control switch quickly controls the control valve 8 to open, and the condensate is discharged through the drain pipe 7. This drainage control method based on the triggering of the tactile switch 13 is more responsive than relying solely on the liquid level sensor 15. As the condensate is continuously discharged and the liquid level drops, the float rod 10 descends with the float ball 11. When the bottom tactile switch 13 touches the bottom limit plate 14, the tactile switch 13 sends a signal to the control switch again. The control switch controls the control valve 8 to close and stop the drainage. The liquid level sensor 15 monitors the condensate level in real time and transmits the data to the control system. It works in conjunction with the tactile switch 13 to form redundant monitoring.

[0040] Furthermore, when maintenance is required on the components within the condensate collection chamber 5, the operator manually pulls the connecting plate 208. Since the front ends of both connecting rods 204 are fixedly connected to the connecting plate 208, pulling the connecting plate 208 will cause the two connecting rods 204 to slide forward synchronously within the sliding grooves 203 on the left and right sides of the outer wall of the condensate collection chamber 5. During the sliding of the connecting rods 204, the locking blocks 205 fixed to the front and rear sides of their top also move accordingly. Originally, the locking blocks 205 were connected to the insert plate 201. The locking groove 209 of the part engages with the sealing plate 6, ensuring that the sealing plate 6 is tightly and securely installed on the top of the condensate collection chamber 5. When the connecting rod 204 moves forward, the locking block 205 gradually disengages from the locking groove 209, releasing the restriction on the insert plate 201. At the same time, the limiting block 206 fixed to the middle of the outer wall of the connecting rod 204 and the spring 207 connected to the front end of the limiting block 206 also begin to function. As the connecting rod 204 slides forward, the spring 207 is compressed, and the spring 207... As the elastic force gradually increases, it provides a backward restoring force to the connecting rod 204. At this time, the insert plates 201 on the left and right sides of the bottom of the sealing plate 6 are no longer constrained by the locking block 205. Since the insert plate 201 is slidably connected to the slots 202 on the left and right sides of the top of the condensate collection chamber 5, the operator only needs to gently lift the sealing plate 6, and the insert plate 201 can be smoothly pulled out along the slot 202, thereby realizing the rapid separation of the sealing plate 6 from the condensate collection chamber 5, which facilitates subsequent operations. When reinstalling the sealing plate 6, the operator first aligns the insert plate 201 with the slot 202, presses down the sealing plate 6, and makes the insert plate 201 fully inserted into the slot 202. At this time, the connecting plate 208 that was pulled earlier is released. Under the elastic force of the spring 207, the connecting rod 204 slides backward to reset, and the locking block 205 re-locks into the slot 209 of the insert plate 201, and the sealing plate 6 is firmly fixed to the top of the condensate collection chamber 5 again, completing the installation operation. The whole process is simple and efficient, greatly improving the convenience of equipment maintenance.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
