Description

Technical Field

[0001] The invention relates to the technical field of steam pipeline drainage, in particular to a drainage device for an overhead steam pipe. Background Art

[0002] During the operation of the steam pipeline, condensate will be generated. This condensate will accumulate at the bottom of the pipeline. If this accumulated water is not discharged in time, it may cause damage to the pipeline over time. In order to prevent this from happening, drain devices are usually installed at low points along the steam pipeline. These devices can effectively drain the accumulated water in the pipeline to ensure that the steam pipeline can continue to operate stably.

[0003] Condensate will form on the outer wall of the steam pipe, which is formed by the condensate in the pipe and the moisture in the atmosphere. The outside of the pipe is exposed to condensate for a long time, which is prone to corrosion, resulting in a thinning of the pipe wall thickness, affecting the load-bearing capacity and safety of the pipe. Condensate condenses on the surface of the pipe to form an insulation layer, which reduces the heat conduction efficiency of the steam pipe itself and increases energy consumption. Condensate on the outside of the pipe will dilute the effective ingredients of the anti-corrosion material, reduce the anti-corrosion effect, and increase the failure rate of the pipe during use. The long-term presence of condensate on the outside of the overhead steam pipe will have many impacts on the pipe itself and the surrounding environment, so it is necessary to take effective measures to remove it.

[0042] Furthermore, the water collecting assembly 103 includes a water collecting box 103a, a water outlet 103b arranged at the bottom of the water collecting box 103a, a water inlet 103c arranged on the side wall of the water collecting box 103a, a sealing block 103d arranged at the bottom of the water outlet 103b, a sliding plate 103e fixedly connected to the top of the sealing block 103d, a moving rod 103f fixedly connected to the bottom of the sliding plate 103e, a return spring 103f fixedly connected to one side of the moving rod 103f, and a pushing hole 103h arranged on one side of the water collecting box 103a.

[0043] Furthermore, the driving assembly 104 includes an L-shaped sliding support plate 104a, a driving motor 104b fixedly connected to the top of the L-shaped sliding support plate 104a, a driving rod 104c arranged on the top of the driving motor 104b, a pushing rod 104d fixedly connected to the top of the driving rod 104c, a hinged column 104e fixedly connected to the top of the pushing rod 104d, a pulling rod 104f rotatably connected to the hinged column 104e, and a rotating member 104g hinged to one end of the pulling rod 104f.

[0044] Preferably, the driving motor 104b is started to drive the driving rod 104c to rotate, and the pushing rod 104d fixedly connected to the top of the driving rod 104c rotates accordingly, pulling the hinged pulling rod 104f to move to one side, so that the buffer base 102a hinged to the pulling rod 104f through the rotating member 104g moves accordingly, and the scraping plate 102f moves in close contact with the bottom of the steam pipe 101h, and the condensed water condensed at the bottom of the steam pipe 101h is scraped off, so that the condensed water slides into the guide groove 102g through the inclined surface of the side of the scraping plate 102f under the action of scraping, and the guide groove 102g in the inclined state is moved. 02g slides to the lowest point under the action of gravity, and slides down to the water inlet 103c of the side wall of the water collecting tank 103a on the curved surface at one end of the guide groove 102g, and applies thrust to the scraper plate 102f at the bottom when the steam pipe 101h expands, so that the scraper base 102d fixedly connected to the bottom of the scraper plate 102f is squeezed toward the two groups of extrusion springs 102c at the bottom to shrink, and the two groups of buffer clamping grooves 102e at both ends of the scraper base 102d move vertically downward under the limitation of the two groups of clamping blocks 102b, so that the scraper plate 102f maintains a close fit with the bottom of the steam pipe 101h.

[0045] Furthermore, the diversion assembly 105 includes a T-shaped plug-in slot 105a, a T-shaped plug-in block 105b arranged inside the T-shaped plug-in slot 105a, a water storage tank 105c fixedly connected to the bottom of the T-shaped plug-in block 105b, a water collection port 105d arranged at the top of the water storage tank 105c, a diversion port 105e arranged at the top of the L-shaped sliding support plate 104a, an extrusion rod 105f fixedly connected to the side wall of the L-shaped sliding support plate 104a, a water collector 105g arranged at the bottom of the steam pipe 101h, and a drain pipe 105h fixedly connected to the bottom of the water collector 105g.

[0046] Preferably, after the condensed water scraped off by the scraper plate 102f flows into the water collecting box 103a through the guide groove 102g, the water collecting box 103a briefly collects the condensed water inside. When the water collecting box 103a moves to the edge of the L-shaped sliding support plate 104a following the buffer base 102a, the extrusion rod 105f fixedly connected to the side wall of the L-shaped sliding support plate 104a passes through the pushing hole 103h on one side of the water collecting box 103a and contacts the moving rod 103f, pushing the moving rod 103f to pull the reset spring 103f to deform, driving the sliding plate 103e fixedly connected to the bottom to move to one side, and the sealing block 103d fixedly connected to the bottom of the sliding plate 103e is made of flexible rubber material, and the arc surface at the bottom is squeezed and contracted by the water outlet 103b, exposing the water outlet 103 at the bottom. b makes the condensed water collected in the water collecting tank 103a flow out through the water outlet 103b. At this time, the water outlet 103b is located above the guide port 105e on the top of the L-shaped sliding support plate 104a. The condensed water flows into the bottom through the water collecting port 105d on the top of the water storage tank 105c under the guiding effect of the guide port 105e and enters the water storage tank 105c. The condensed water generated in the steam pipe 101h will flow to the lowest point of the water collector 105g. The water collector 105g is used to collect the condensed water generated in the steam pipe 101h and discharge it into the water storage tank 105c through the drain pipe 105h at the bottom to avoid the phenomenon of water accumulation damaging the pipeline. The water storage tank 105c is plugged into the matching T-shaped plug slot 105a through the T-shaped plug block 105b fixedly connected at the top for easy processing after collection.

[0047] Furthermore, the bases of the first C-shaped fixing seat 101e, the second C-shaped fixing seat 101f and the third C-shaped fixing seat 101g are increased in proportion, and the inner walls of the first C-shaped fixing seat 101e, the second C-shaped fixing seat 101f and the third C-shaped fixing seat 101g are configured to be arc-shaped.

[0048] Furthermore, the scraper base 102d is set to a U shape, the two ends of the top of the scraper plate 102f are set to inclined surfaces, the scraper plate 102f is set in the middle of the scraper base 102d, the guide groove 102g is set to an inclined state, the clamping block 102b is adapted to the buffer clamping groove 102e, and one end of the guide groove 102g is set to an arc surface.

[0049] Furthermore, the bottom of the water inlet 103c is set as an arc surface, the bottom of the sealing block 103d is set as an arc surface, and one end of the return spring 103f is fixedly connected to the inner wall of the water collecting box 103a.

[0050] Furthermore, one side of the rotating member 104g is fixedly connected to the outer wall of the buffer base 102a, the T-shaped plug slot 105a is adapted to the T-shaped plug block 105b, the water collection port 105d is arranged at the bottom of the guide port 105e, and the extrusion rod 105f is adapted to the push hole 103h.

[0051] It should be noted that the inner walls of the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g are arranged in an arc shape, which can better form a wrapping support force for the bottom of the steam pipe and enhance stability. The bases of the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g are proportionally increased, so that the steam pipe forms a certain inclination when it expands during operation, which is convenient for condensed water to flow to a lower place when it gathers at the bottom, so that the scraper 102f can quickly scrape off the condensed water, and avoid the condensed water from adhering to the outer wall of the steam pipe for a long time and causing corrosion to the outer wall of the steam pipe. The steam pipe expands during operation and exerts a driving force on the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g, squeezing and A plurality of buffer springs 101d fixedly connected to the side walls of a C-type fixing seat 101e, a second C-type fixing seat 101f and a third C-type fixing seat 101g cause the plurality of buffer springs 101d to contract, and the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g move to both sides to adapt to the diameter of the steam pipe after expansion. When the steam pipe contracts, the plurality of buffer springs 101d fixedly connected to the side walls of the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g lose their extrusion force, and the rebound force generated pushes the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g to move toward the middle, thereby maintaining a wrapped support for the steam pipe and enhancing the stability of the steam pipe.

[0052] When in use, the steam pipe is limited and fixed. When the steam pipe is working, it expands and exerts a driving force on the first C-shaped fixing seat 101e, the second C-shaped fixing seat 101f and the third C-shaped fixing seat 101g, squeezing a plurality of groups of buffer springs 101d fixedly connected to the side walls of the first C-shaped fixing seat 101e, the second C-shaped fixing seat 101f and the third C-shaped fixing seat 101g, so that the plurality of groups of buffer springs 101d are contracted. The C-type fixing seat 101g moves to both sides to adapt to the diameter of the steam pipe after expansion. When the steam pipe shrinks, the rebound force generated by the loss of extrusion force of several groups of buffer springs 101d fixedly connected to the side walls of the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g pushes the first C-type fixing seat 101e, the second C-type fixing seat 101f and the third C-type fixing seat 101g to move toward the middle, maintaining the wrapped support for the steam pipe and enhancing the stability of the steam pipe.

[0053] To scrape off the condensed water at the bottom of the steam pipe, start the driving motor 104b to drive the driving rod 104c to rotate, and the pushing rod 104d fixedly connected to the top of the driving rod 104c rotates accordingly, pulling the hinged pulling rod 104f to move to one side, so that the buffer base 102a hinged to the pulling rod 104f through the rotating member 104g moves accordingly, and the scraping plate 102f moves in close contact with the bottom of the steam pipe 101h to scrape off the condensed water condensed at the bottom of the steam pipe 101h, so that the condensed water slides into the guide groove 102g through the inclined surface of the side of the scraping plate 102f under the action of scraping, and in the inclined state The guide groove 102g slides to the lowest point under the action of gravity, and slides toward the water inlet 103c of the side wall of the water collecting tank 103a on the curved surface at one end of the guide groove 102g. When the steam pipe 101h expands, a thrust is applied to the scraper plate 102f at the bottom, so that the scraper base 102d fixedly connected to the bottom of the scraper plate 102f is squeezed toward the two groups of extrusion springs 102c at the bottom to cause contraction. The two groups of buffer clamping grooves 102e at both ends of the scraper base 102d move vertically downward under the limitation of the two groups of clamping blocks 102b, so that the scraper plate 102f maintains a close fit with the bottom of the steam pipe 101h.

[0054] The scraped condensed water is collected to avoid corrosion to the base. After the condensed water scraped off by the scraper plate 102f flows into the water collecting box 103a through the guide groove 102g, the water collecting box 103a briefly collects the condensed water inside. When the water collecting box 103a follows the buffer base 102a to move to the edge of the L-shaped sliding support plate 104a, the extrusion rod 105f fixedly connected to the side wall of the L-shaped sliding support plate 104a passes through the pushing hole 103h on one side of the water collecting box 103a and contacts the moving rod 103f, pushing the moving rod 103f to pull the reset spring 103f to deform, driving the sliding plate 103e fixedly connected to the bottom to move to one side. The sealing block 103d fixedly connected to the bottom of the sliding plate 103e is made of flexible rubber material, and the arc surface at the bottom is squeezed and contracted by the water outlet 103b, exposing the bottom. The water outlet 103b allows the condensed water collected inside the water collecting tank 103a to flow out through the water outlet 103b. At this time, the water outlet 103b is located above the guide port 105e on the top of the L-shaped sliding support plate 104a. The condensed water flows into the bottom through the water collecting port 105d on the top of the water storage tank 105c under the guiding effect of the guide port 105e and enters the water storage tank 105c. The condensed water generated inside the steam pipe 101h will flow to the lowest point of the water collector 105g. The water collector 105g is used to collect the condensed water generated inside the steam pipe 101h and discharge it into the water storage tank 105c through the drain pipe 105h at the bottom to avoid water accumulation and damage to the pipeline. The water storage tank 105c is plugged into the matching T-shaped plug slot 105a through the T-shaped plug block 105b fixedly connected at the top for easy collection and processing after it is full.

[0055] In summary, the present invention cleans the condensed water formed on the outer wall of the steam pipe by setting a fixed cleaning unit, expands the fixed component to support and fix the steam pipe while adapting to the change of the diameter of the steam pipe, improves the stability of the steam pipe support, starts the driving component to drive the scraping component to scrape the condensed water formed on the outer wall of the pipe, and guides it into the water collection component to avoid falling to the bottom and causing corrosion, thereby improving the heat conduction efficiency of the steam pipe itself, reducing energy consumption, and preventing the condensed water from adhering to the outer wall of the steam pipe for a long time and corroding the pipe, thereby reducing the thickness of the pipe wall and affecting the bearing capacity and safety of the pipe. When the water collection component moves to contact with the guide component, the water outlet at the bottom of the water collection component is opened to allow the collected condensed water to flow into the guide component, which is convenient for processing, reduces the failure rate of the pipe during use, and improves the service life and work efficiency of the steam pipe.

[0056] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary.
