Description

Technical Field

[0001] This invention belongs to the field of heat exchange equipment technology, specifically a steam accumulator. Background Technology

[0002] A steam accumulator is a device used to balance short-term peak loads. It absorbs excess steam when the system load decreases and releases steam when the system load increases. The main components of a steam accumulator include a water tank, a heated steam inlet, an output steam outlet, a converter, and steam distribution pipes. The water tank is filled with softened water. When the system load decreases, excess steam generated by the boiler is charged into the softened water through the heating device and stored, causing the pressure and temperature of the water inside the accumulator to rise, forming saturated water at a certain pressure. When the system load increases, the saturated water in the tank evaporates due to the pressure drop, supplying steam to the users.

[0003] A steam accumulator with publication number CN118424021B utilizes the kinetic energy of steam flowing in the main steam inlet pipe to drive two descaling components to clean the steam inlet branch pipe and nozzles, preventing scale buildup and ensuring smooth water flow. However, both descaling components operate via steam flow, meaning that the descaling components work simultaneously with the steam accumulator, with the descaling scraper and head continuously scraping and cleaning. However, scale buildup near the nozzles is relatively slow, and frequent scraping easily causes nozzle wear and damage. After continuous operation for a period, the nozzles become worn and unable to contact the descaling components, resulting in ineffective descaling. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of wear and tear on existing pipeline components due to frequent movement of descaling equipment, the present invention provides a steam accumulator comprising: Heat storage components; The condenser, located inside the heat storage unit, cools the incoming steam into liquid water; The control components are attached to the outside of the condenser components; The heat storage component includes: Insulated heat storage tank; The condensation component includes: A spiral-shaped pipe is provided with a connecting port on the left side of the inner cavity of the spiral-shaped pipe, and the bottom end of the steam inlet is connected to the inner cavity of the spiral-shaped pipe through the connecting port. The inner slip rings are evenly distributed on the inner wall of the loop pipe and are used to scrape off the scale on the inner wall of the loop pipe. The diameter of the outer surface of the inner slip ring is the same as the diameter of the inner wall of the loop pipe. The drainage components are evenly distributed at the bottom of the inner cavity of the loop-shaped tube.

[0005] Furthermore, the inner slip ring includes: The wall-adhering slip ring has sharp chamfers symmetrically formed on the front and rear sides of its outer surface. When the wall-adhering slip ring slides along the inner wall of the loop pipe through its sharp chamfers, it scrapes off the scale adhering to the inner wall of the loop pipe. A metal inner ring is evenly distributed in the inner cavity of the slip ring attached to the wall, which increases the magnetic attraction force on the inner slip ring. The outer surface of the sensing inner ring is fixedly connected to the middle of the inner wall of the sliding ring attached to the wall, and the inner cavity of the sensing inner ring is uniformly provided with shaking ends. When the shaking ends of the sensing inner ring vibrate, the sensing inner ring will be triggered to emit a signal to the outside.

[0006] Furthermore, the control component includes: The outer surface of the wall-mounted outer rail is fixedly connected to the outer surface of the loop-shaped pipe. The lower surface of the wall-mounted outer rail is inserted into the inner wall of the heat storage tank through a fixed support rod. The outer surface of the wall-mounted outer rail is concave to fit the outer surface of the loop-shaped pipe. The movable slider is evenly distributed inside the outer rail attached to the wall, and an adsorption magnetic block is provided on the side of the movable slider cavity near the loop tube. The magnetic force of the adsorption magnetic block controls the sliding movement of the inner slip ring inside the loop tube. The wall-mounted roller is set on the outer surface of the movable slider and is connected to the inner wall of the wall-mounted outer rail by a built-in motor. The movable slider drives the wall-mounted roller to roll by the internal motor, thereby sliding directionally along the inner wall of the wall-mounted outer rail. Spacing strips are symmetrically arranged on both sides of the outer surface of the moving slider. The spacing strips separate adjacent moving sliders to avoid magnetic interference.

[0007] Furthermore, the heat storage component also includes: The steam inlet is located at the upper part of the inner cavity of the heat storage tank to guide external steam into the device. The pressure relief port is located at the upper part of the inner cavity of the heat storage tank; The parallel outlet is located at the upper part of the inner cavity of the heat storage tank, and the top of the parallel outlet extends to the outside of the heat storage component. The drain outlet is located at the bottom of the inner cavity of the heat storage tank; The external pipe is located on the right side of the inner cavity of the heat storage tank; The heating element is located inside the heat storage tank and is used to compensate for the heat inside the heat storage tank.

[0008] Furthermore, the heating component includes: End turntable, the outer surface of which is fixedly connected to the left side of the inner wall of the heat storage tank; The built-in rotating ring has its outer surface rotatably connected to the inner wall of the end turntable via a rotating wheel, and the right side of the outer surface of the built-in rotating ring is symmetrically provided with an adapter socket. An extension plate is provided, the outer surface of which is slidably connected to the inner wall of the heat storage tank, and the left end of which is inserted into the outer surface of the built-in rotating ring through an adapter socket. Heat transfer plates are symmetrically arranged on the upper and lower sides of the inner cavity of the extension plate. The heat transfer plates compensate for the heat of the liquid water inside the heat storage component, causing the water to evaporate into water vapor.

[0009] Furthermore, the drainage component includes: A guide tube, the top end of which is inserted into the bottom of the inner cavity of a loop-shaped tube via an insertion interface; A sliding tube is provided, wherein the outer surface of the sliding tube is slidably connected to the inner wall of the guide tube, and the inner cavity of the sliding tube is uniformly provided with discharge slots. An elastic sleeve is fixedly connected to the top end of the sliding tube, and the top end of the elastic sleeve is inserted into the inner wall of the guide tube.

[0010] Furthermore, the drainage component also includes: The built-in sliding plate has an outer surface that is slidably connected to the inner wall of the sliding tube. The outer surface of the built-in sliding plate is evenly provided with external scrapers, and the outer surface of the external scrapers is slidably connected to the inner cavity of the sliding tube through the discharge slot. When the external scrapers on the outer surface of the built-in sliding plate slide along the discharge slot of the sliding tube, they can scrape off the scale inside the discharge slot, thereby clearing the discharge slot. An isolation pusher, the outer surface of which is fixedly connected to the bottom of the inner cavity of the sliding tube; A vertical push rod is provided, with a compression spring fitted around the bottom of its outer surface. The outer surface of the vertical push rod is slidably connected to the axis of the inner wall of the isolation push cylinder, and the top end of the vertical push rod is inserted into the axis of the inner cavity of the built-in slide plate.

[0011] The beneficial effects of this invention are as follows: 1. This device can collect the emitted high-temperature water vapor and then discharge it when heating is needed. Since the water vapor flows inside the loop pipe, long-term use will cause scale to adhere to the inner wall of the pipe and the nozzle, leading to pipe blockage. Therefore, a sliding inner slip ring is installed inside the loop pipe. The control component periodically controls the inner slip ring to actively slide along the inner wall of the loop pipe, scraping off the scale adhering to the inner wall of the loop pipe, thus achieving a unclogging effect. Since the inner slip ring will be cleaned periodically according to the working time of the device, the friction frequency with the loop pipe is reduced, thereby extending the service life of the loop pipe.

[0012] 2. The inner slip ring of this device slides along the inner wall of the loop-shaped pipe by magnetic traction. Its relatively simple structure provides strong anti-interference and waterproof performance. It will not malfunction due to high temperatures or moisture on the inner wall of the loop-shaped pipe. To prevent hard scale from jamming the inner slip ring and causing misalignment between the sliding block and the inner slip ring, a sensing inner ring is installed on the inner side of the inner slip ring. The stability of the inner slip ring during movement is judged by the shaking end of the sensing inner ring. By repeatedly moving the inner slip ring, the scale is broken up, preventing misalignment.

[0013] 3. When it is necessary to release the water vapor inside the heat storage component, the internal heating component can compensate for the heat of the water vapor, so that the liquefied water vapor can be re-vaporized and discharged through the parallel outlet at the top. The end turntable can control the internal rotating ring to rotate, so that the position swept by the heat transfer plate changes, thereby making the heating range more extensive.

[0014] 4. Water vapor flows through the loop pipe. After continuous use for a period of time, scale and accumulated residue may block the discharge slot of the sliding tube. At this time, the outer scraper outside the built-in sliding plate will slide along the wall of the discharge slot of the sliding tube. On the one hand, it will scrape off the scale attached to the discharge slot, and on the other hand, it will break up the accumulated residue, thus clearing the discharge slot. It will also guide the water accumulated at the bottom of the sliding tube to the discharge slot. Therefore, the draining component can prevent the water vapor inside the heat storage tank from flowing back and ensure that the heat storage tank has a good heat insulation effect.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a steam accumulator, comprising: Heat storage component 1; The condenser 6 is located inside the heat storage unit 1 and cools the incoming steam into liquid water; The control component 7 is attached to the outside of the condenser component 6; The heat storage component 1 includes: Insulated heat storage tank 11; The condenser component 6 includes: The spiral pipe 61 has a connecting port on the left side of its inner cavity, and the bottom end of the steam inlet 2 is connected to the inner cavity of the spiral pipe 61 through the connecting port. The inner slip ring 62 is evenly distributed on the inner wall of the loop pipe 61 and is used to scrape off the scale on the inner wall of the loop pipe 61. The diameter of the outer surface of the inner slip ring 62 is the same as the diameter of the inner wall of the loop pipe 61. The draining components 63 are evenly distributed at the bottom of the inner cavity of the loop pipe 61.

[0019] The inner slip ring 62 includes: The wall-adhering slip ring 621 has sharp chamfers symmetrically opened on the front and rear sides of its outer surface. When the wall-adhering slip ring 621 slides along the inner wall of the loop pipe 61 through its sharp chamfers, it scrapes off the scale adhering to the inner wall of the loop pipe 61. The inner metal ring 622 is evenly distributed in the inner cavity of the wall-mounted slip ring 621, and the magnetic attraction force on the inner slip ring 62 is increased through the inner metal ring 622. The outer surface of the sensing inner ring 623 is fixedly connected to the middle of the inner wall of the sliding ring 621. The inner cavity of the sensing inner ring 623 is uniformly provided with shaking ends 624. When the shaking ends 624 of the sensing inner ring 623 shake, the sensing inner ring 623 will be triggered to emit a signal to the outside.

[0020] Control component 7 includes: The outer surface of the wall-mounted outer rail 71 is fixedly connected to the outer surface of the loop pipe 61. The lower surface of the wall-mounted outer rail 71 is inserted into the inner wall of the heat storage tank 11 through the fixed support rod 72. The outer surface of the wall-mounted outer rail 71 is concave to fit the outer surface of the loop pipe 61. The movable slider 73 is evenly arranged inside the outer rail 71 attached to the wall, and an adsorption magnetic block 76 is provided on the side of the inner cavity of the movable slider 73 near the loop tube 61. The magnetic force of the adsorption magnetic block 76 controls the sliding movement of the inner slip ring 62 inside the loop tube 61. The wall-mounted roller 74 is disposed on the outer surface of the movable slider 73 and is connected to the inner wall of the wall-mounted outer rail 71 by a built-in motor. The movable slider 73 drives the wall-mounted roller 74 to roll by the internal motor, thereby sliding directionally along the inner wall of the wall-mounted outer rail 71. Spacing strips 75 are symmetrically arranged on both sides of the outer surface of the movable slider 73. The spacing strips 75 separate adjacent movable sliders 73 to avoid magnetic interference.

[0021] The heat storage component 1 also includes: Steam inlet 2 is located at the upper part of the inner cavity of the heat storage tank 11 to guide external steam into the device. Pressure relief port 3 is located at the upper part of the inner cavity of the heat storage tank 11; Parallel outlet 4 is located in the upper part of the inner cavity of the heat storage tank 11, and the top of parallel outlet 4 extends to the outside of the heat storage component 1. The drain outlet 12 is located at the bottom of the inner cavity of the heat storage tank 11; The external pipe 13 is located on the right side of the inner cavity of the heat storage tank 11; Heating component 5 is installed inside the heat storage tank 11 to compensate for the heat inside the heat storage tank 11.

[0022] When the device is in operation, the steam is connected to the external steam outlet through the steam inlet 2. After the steam enters the interior of the heat storage component 1 through the steam inlet 2, it goes directly into the interior of the loop pipe 61. Some of the steam condenses into liquid water and is stored inside the loop pipe 61. Then, the steam pressurizes the drain components 63 on both sides of the loop pipe 61 through the air pressure. After the drain components 63 are opened, the steam and the liquid water inside the loop pipe 61 enter the interior of the heat storage tank 11.

[0023] Because scale will gradually accumulate inside the loop pipe 61, after a period of water vapor storage, the control component 7 is activated. At this time, the moving slider 73 inside the control component 7 begins to slowly slide along the inner wall of the outer wall rail 71 via the wall-mounted roller 74. Since adjacent moving sliders 73 are connected by the spacer strap 75, when all moving sliders 73 slide clockwise along the inner wall of the outer wall rail 71 at the same time, the adsorption magnet 76 inside each moving slider 73 will drive the corresponding inner slip ring 62 inside the loop pipe 61 to move synchronously through magnetic attraction. As the inner slip ring 62 moves along the loop pipe 61, it will scrape off the scale on the inner wall of the loop pipe 61 through the sharp side surface. After the scale is removed from the inner wall of the loop pipe 61, it is flushed into the interior of the heat storage tank 11 by the subsequent water vapor and flowing liquid, and settles at the bottom of the heat storage tank 11, and is discharged through the drain port 12 at the bottom of the heat storage tank 11.

[0024] The wall-adhering slip ring 621, through its inner metal ring 622, increases the magnetic force with the adsorbing magnetic block 76. Under normal circumstances, the wall-adhering slip ring 621 maintains a relatively stable state when sweeping across the inner wall of the loop-shaped pipe 61. However, if the scale on a certain part of the inner wall of the loop-shaped pipe 61 is particularly stubborn, the wall-adhering slip ring 621 may not be able to easily scrape off the scale upon contact, thus impacting the scale and causing strong vibration. In this case, the shaking end 624 of the sensing inner ring 623... The vibration causes shaking, which in turn stops the sliding block 73 by signal control, preventing it from moving further. However, the wall-mounted slip ring 621 gets stuck in the scale area and cannot move synchronously, causing misalignment between the wall-mounted slip ring 621 and the sliding block 73. At this point, the sliding block 73 slides in the opposite direction, causing the wall-mounted slip ring 621 to slide in the opposite direction, and then continues to move clockwise, allowing the wall-mounted slip ring 621 to repeatedly impact the scale in this area, thereby breaking and scraping off the scale, thus achieving the descaling work.

[0025] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the heating component 5 includes: End turntable 51, the outer surface of end turntable 51 is fixedly connected to the left side of the inner wall of the heat storage tank 11; The built-in rotating ring 52 has its outer surface rotatably connected to the inner wall of the end turntable 51 via a rotating wheel, and the right side of the outer surface of the built-in rotating ring 52 is symmetrically provided with adapter ports. The extension plate 53 has its outer surface slidably connected to the inner wall of the heat storage tank 11, and its left end is inserted into the outer surface of the built-in rotating ring 52 through an adapter socket. The heat transfer plate 54 is symmetrically arranged on the upper and lower sides of the inner cavity of the extension plate 53. The heat transfer plate 54 compensates for the heat of the liquid water inside the heat storage component 1, causing the water to evaporate into water vapor.

[0026] The drain component 63 includes: The top end of the guide tube 631 is inserted into the bottom of the inner cavity of the loop tube 61 through the insertion interface; The sliding tube 633 has its outer surface slidably connected to the inner wall of the guide tube 631, and the inner cavity of the sliding tube 633 is evenly provided with discharge slots. The top end of the sliding tube 633 is fixedly connected to an elastic sleeve 632, and the top end of the elastic sleeve 632 is inserted into the inner wall of the guide tube 631.

[0027] The drain component 63 also includes: The built-in sliding plate 635 has its outer surface slidably connected to the inner wall of the sliding tube 633. The outer surface of the built-in sliding plate 635 is evenly provided with external scrapers, and the outer surface of the external scrapers is slidably connected to the inner cavity of the sliding tube 633 through the discharge slot. When the external scrapers on the outer surface of the built-in sliding plate 635 slide along the discharge slot of the sliding tube 633, they can scrape off the scale inside the discharge slot, thereby clearing the discharge slot. The outer surface of the isolation push cylinder 634 is fixedly connected to the bottom of the inner cavity of the sliding tube 633; A vertical push rod 636 has a compression spring sleeved on the bottom of its outer surface. The outer surface of the vertical push rod 636 is slidably connected to the axis of the inner wall of the isolation push cylinder 634, and the top of the vertical push rod 636 is inserted into the axis of the inner cavity of the built-in slide plate 635.

[0028] When it is necessary to release the water vapor inside the heat storage component 1, the internal heating component 5 can compensate the water vapor with heat, so that the liquefied water vapor can be re-vaporized and discharged through the parallel outlet 4 at the top. The end turntable 51 can control the built-in rotating ring 52 to rotate, so that the position swept by the heat transfer guide plate 54 changes, thereby making the heating range more extensive.

[0029] Water vapor flows through the loop pipe 61 and is discharged into the heat storage tank 11 from the bottom drain component 63. At this time, the sliding tube 633 slides down the inner wall of the closed guide tube 631 under the action of air pressure. At this time, the elastic sleeve 632 is stretched, and then the water vapor and scale residue inside the loop pipe 61 are directly discharged into the heat storage tank 11 through the discharge slot of the sliding tube 633. After continuous use for a period of time, scale and accumulated residue may fill the discharge slot of the sliding tube 633. When the outlet is blocked, the isolation pusher 634 inside the sliding tube 633 controls the vertical push rod 636 to slide repeatedly in the vertical direction, thereby driving the built-in sliding plate 635 to slide. As a result, the outer scraper of the built-in sliding plate 635 slides along the wall of the discharge slot of the sliding tube 633, scraping off the scale attached to the discharge slot and breaking up the accumulated residue, thus clearing the discharge slot and diverting the water accumulated at the bottom of the sliding tube 633 to the discharge slot.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
