Description

Technical Field

[0001] The present invention relates to the technical field of blast furnace production equipment, in particular to a cleaning tool for a cover groove of a discharging device and a cleaning method for the cover groove. Background Art

[0002] The blast furnace's venting device is a crucial piece of equipment. Installed at the furnace's roof, it releases the internal airflow into the atmosphere, thereby relieving the furnace's pressure. During periods of blast furnace downtime, the venting device is typically opened to relieve pressure.

[0003] The relief device includes a relief valve and a hydraulic cylinder assembly and a counterweight both of which are arranged below the relief valve. The relief valve includes a valve seat and a valve cover. The valve seat is arranged in a relief pipe on the top of the blast furnace. The valve cover is hinged to the valve seat through a hinge component and is used to cover the valve port of the valve seat. The hydraulic cylinder assembly and the counterweight are respectively located on opposite sides of the valve seat, and the upper end of the hydraulic cylinder assembly and the upper end of the counterweight are both connected to the valve cover. The hydraulic cylinder assembly is used to drive the valve cover to flip around the hinge component to open or close the valve port. The counterweight can be raised and lowered in the vertical direction to loosen or tighten the valve cover. After the blast furnace is relieved, the valve cover is tightened to the valve seat by the counterweight to prevent the valve cover from being opened due to misoperation of the hydraulic cylinder assembly. At the same time, when the hydraulic cylinder assembly is not started, the high-pressure gas inside the blast furnace is prevented from blowing the valve cover open. An annular sealing silicone layer protrudes from the end of the valve port. A recessed groove corresponding to the silicone layer is located on the side of the valve cover where it covers the valve seat. When the valve cover closes the valve port, the silicone layer presses into the groove, sealing the valve cover and valve seat. Whether the relief valve is airtight depends primarily on whether the silicone layer fits perfectly into the groove.

[0004] During the blast furnace smelting process, the top gas contains a large amount of dust and other impurities. After a certain period of production, the dust will adhere to the area near the cover groove and form. When the valve cover is opened during the blast furnace shutdown, the high-pressure gas will instantly blow the dust adhered to the cover groove into the interior of the cover groove. Under the action of steam, the dust easily adheres to and blocks the cover groove, resulting in the valve cover not being able to tightly bond with the sealing silicone layer when closing, causing air leakage. Therefore, the adhesive inside the cover groove must be cleaned after each opening of the valve cover.

[0005] In the prior art, the closure trough is typically cleaned manually. At least two people must climb to a height of several dozen meters above the furnace roof to use high-pressure air to purge any adhesive from within the closure trough. During this cleaning process, a large amount of hot air from within the blast furnace is ejected, which can easily burn the operators. Furthermore, this hot air contains a large amount of gas, which can easily cause inhalation and poisoning to operators working near the valve cover. This is labor-intensive and poses a high safety risk. Summary of the Invention

[0013] A traction assembly is provided on the support member and is connected to the bracket. When the counterweight member rises, the traction assembly pulls the bracket to slide toward the second end to drive the purge assembly close to the valve cover. When the counterweight member descends, the traction assembly pulls the bracket to slide toward the first end to drive the purge assembly away from the valve cover.

[0014] As an optimal technical solution for the cover groove cleaning tool of the release device, the traction assembly includes a traction wheel and a traction wire, the traction wheel is arranged at a position of the support member close to the second end, one end of the traction wire is connected to the traction wheel, and the other end is connected to the bracket, and the counterweight is in contact with the rotating surface of the traction wheel.

[0015] As a preferred technical solution of the covering groove cleaning tool of the dispersion device, the traction assembly also includes a first positioning wheel, a second positioning wheel and a redirecting wheel, all of which are arranged on the support member, the first positioning wheel is located between the bracket and the traction wheel, the redirecting wheel is close to the first end, the second positioning wheel is located between the redirecting wheel and the bracket, and the traction wire is located between the traction wheel and the bracket and is sequentially wound around the first positioning wheel, the second positioning wheel and the redirecting wheel.

[0016] As an optimal technical solution for the cover groove cleaning tool of the dispersion device, one side of the support member has a slide rail, the length of the slide rail extends from the first end toward the second end, and the bottom of the bracket is provided with a pulley abutting against the slide rail, and the pulley can slide along the length direction of the slide rail.

[0017] As a preferred technical solution of the cover groove cleaning tool of the diffusion device, the purge assembly is rotatably connected to the bracket through a rotary joint.

[0018] As an optimal technical solution for the cover groove cleaning tool of the dispersion device, the purge assembly includes a high-pressure nozzle and a connecting pipe connected to the gas compressor, one end of the connecting pipe is connected to the rotary joint, and the high-pressure nozzle is arranged at the end of the connecting pipe away from the bracket.

[0019] As an optimal technical solution for the cover groove cleaning tool of the dispersing device, the air flow interruption of the high-pressure nozzle is controlled by a control component, the control component includes a control valve and a sensing component, the sensing component includes an induction switch and an induction sheet that senses the induction switch, the induction switch is arranged between the first end and the bracket of the slide rail, the induction sheet is arranged on the bracket, and the induction switch is communicatively connected to the control valve.

[0025] Step S30: Use a monitoring component to monitor the covering groove. If there is no adhesive in the covering groove, the purge component stops purging. If there is adhesive in the covering groove, repeat step S20.

[0026] The beneficial effects of the present invention are as follows: when the valve port needs to be opened, the driving member drives the valve cover to flip around the hinge member, and at the same time the counterweight member rises to release the tension on the valve cover. During the process of the counterweight member rising, the traction assembly drives the bracket and the purge assembly to move toward the first end of the support plate, so that the purge assembly is close to the cover groove of the valve cover, thereby improving the purge effect of the purge assembly on the adhesive inside the cover groove.

During the process of the counterweight member descending, the traction assembly drives the bracket and the purge assembly to move toward the second end of the support plate, so that the purge assembly is away from the valve cover, thereby preventing the valve cover from covering the valve port. The cover groove cleaning tool of the release device with this structure can clean the cover groove with the purge assembly, and there is no need to manually climb onto the valve seat to clean the cover groove. It has the characteristics of low labor intensity and high safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0034] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0035] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0036] like Figures 1 to 3As shown, the present invention provides a cover groove cleaning tool for a relief device (referred to as the cover groove cleaning tool in this specification). The relief device includes a relief valve and a driving member 3 and a counterweight 4 both arranged below the relief valve. The relief valve includes a valve seat 2 and a valve cover 1. The valve seat 2 is arranged on a relief pipe 100 on the top of the blast furnace. The valve cover 1 is hinged to the valve seat 2 and is used to cover the valve port of the valve seat 2. The driving member 3 and the counterweight 4 are respectively located on opposite sides of the valve seat 2, and the upper end of the driving member 3 and the upper end of the counterweight 4 are connected to the valve cover 1. The driving member 3 is used to drive the valve cover 1 to flip around the hinge member 202 to open or close the valve port. The counterweight 4 can be raised and lowered in the vertical direction to loosen or tighten the valve cover 1 on the valve seat 2. The driving member 3 includes a hydraulic cylinder 301 and a connecting chain 302 connected to the telescopic rod of the hydraulic cylinder 301. The end of the connecting chain 302 away from the hydraulic cylinder 301 is connected to the valve cover 1. A sealing layer 201 is provided at the end of the valve port. The covering groove 101 is annular and recessed on the side of the cover plate 1 that covers the valve port. When the valve cover 1 covers the valve port, the sealing layer 201 is pressed into the covering groove 101, achieving a seal between the valve cover 1 and the valve seat 2. When the relief device is in use, the driving member 3 drives the valve cover 1 to open while the counterweight 4 rises, releasing the locking force on the valve cover 1. When the driving member 3 drives the valve cover 1 to close, the counterweight 4 descends, providing a tensioning force on the valve cover 1, so that the closed valve cover 1 is tightened against the valve seat 2. The cover groove cleaning tool includes a support member 6, a purge assembly 7 and a bracket 8 slidably set on the support member 6. The purge assembly 7 is connected to the gas compressor and is used to purge high-pressure gas into the cover groove 101 on the valve cover 1. The support member 6 is fixed below the valve seat 2. The support member 6 has a first end and a second end. The first end is close to the valve seat 2, and the second end is close to the counterweight 4. The length direction of the support member 6 extends from the first end toward the second end. The purge assembly 7 is supported above the support member 6 by the bracket 8. The traction assembly 5 is set on the support member 6. When the counterweight 4 rises, the traction assembly 5 pulls the bracket 8 to slide toward the second end to drive the purge assembly 7 close to the valve cover 1. When the counterweight 4 falls, the traction assembly 5 pulls the bracket 8 to slide toward the first end to drive the purge assembly 7 away from the valve cover 1.

[0037] The purge assembly 7 is connected to a gas compressor, which provides high-pressure air to the purge assembly 7. When the valve cover 1 is opened, the purge assembly 7 blows high-pressure gas greater than 1.0 MPa into the cover groove 101 on the valve cover 1 to blow away the adhesive stuck inside the cover groove 101, preventing the adhesive inside the cover groove 101 from causing the sealing layer 201 on the valve seat 2 to be unable to be pressed into the cover groove 101, thereby ensuring the airtightness between the valve cover 1 and the valve seat 2. When the counterweight 4 is raised or lowered, the traction assembly 5 pulls the bracket 8 and the purge assembly 7 to move along the length direction of the support 6. When the valve cover 1 needs to be opened, the driving member 3 drives the valve cover 1 to flip around the hinge part 202, and the counterweight 4 rises at the same time, releasing the tension on the valve cover 1. During the rising process of the counterweight 4, the traction assembly 5 drives the bracket 8 and the purge assembly 7 to move toward the first end of the support plate, so that the purge assembly 7 is close to the covering groove 101 of the valve cover 1, thereby improving the purge effect of the purge assembly 7 on the adhesive inside the covering groove 101. When the valve cover 1 needs to be closed, the driving member 3 contracts and drives the valve cover 1 to flip and reset around the hinge part 202, so that the valve cover 1 covers the valve port. At the same time, the counterweight 4 descends and tightens the valve cover 1 on the valve seat 2. During the descending process of the counterweight 4, the traction assembly 5 drives the bracket 8 and the purge assembly 7 to move toward the second end of the support member 6, so that the purge assembly 7 is away from the valve cover 1, to prevent the existence of the purge assembly 7 from causing position interference with the valve cover 1 and causing the valve cover 1 to be unable to cover the valve port. The cover groove cleaning tool of the discharging device with this structure, the purge component 7 can clean the cover groove 101, and there is no need to manually climb onto the valve seat 2 to clean the cover groove 101. It has the characteristics of low labor intensity and high safety.

[0038] The traction assembly 5 includes a traction wheel 501 and a traction wire 502. The traction wheel 501 is positioned near the second end of the support member 6. One end of the traction wire 502 is connected to the traction wheel 501, and the other end is connected to the bracket 8. The counterweight 4 abuts the rotating surface of the traction wheel 501. In this embodiment, the traction wheel 501 is fixed to the support member 6 via a fixing member 13. The counterweight 4 includes a counterweight block 401 and a counterweight chain 402. One end of the counterweight chain 402 is connected to the valve cover 1, and the other end is connected to the counterweight block 401. The rotating surface of the traction wheel 501 abuts the position of the counterweight chain 402 located between the valve cover 1 and the counterweight block 401. During the raising and lowering of the counterweight chain 402, the counterweight chain 402 rotates the traction wheel 501 due to friction, thereby driving the traction wire 502 to pull the bracket 8 to slide along the length of the support member 6. In this embodiment, when the counterweight 4 rises, the counterweight chain 402 drags the traction wheel 501 to rotate clockwise, releasing the traction wire 502. Due to the rigidity of the traction wire 502, the bracket 8 can be pulled toward the first end during the release of the traction wire 502, bringing the purge assembly 7 closer to the valve cover 1. When the counterweight 4 descends, the counterweight chain 402, under the action of friction, drags the traction wheel 501 to rotate counterclockwise, reeling in the wire, and pulling the bracket 8 toward the second end, moving the purge assembly 7 away from the valve cover 1. In actual implementation, a storage compartment 17 for storing the counterweight 401 is provided below the counterweight 4.

[0039] Specifically, the traction assembly 5 further includes a first positioning wheel 504, a second positioning wheel 505, and a redirecting wheel 503, all of which are arranged on the support member 6. The first positioning wheel 504 is located between the bracket 8 and the traction wheel 501, the redirecting wheel 503 is close to the first end, and the second positioning wheel 505 is located between the redirecting wheel 503 and the bracket 8. The first positioning wheel 504, the second positioning wheel 505, and the redirecting wheel 503 are sequentially wound around the portion of the traction wire 502 located between the traction wheel 501 and the bracket 8. The first positioning wheel 504 and the second positioning wheel 505 are provided to position the traction wire 502, which is conducive to guiding the bracket 8 to slide along the length direction of the support member 6.

[0040] Furthermore, a slide rail 601 is provided on one side of the support member 6. The length of the slide rail 601 extends from the first end toward the second end. A pulley 9 is provided at the bottom of the bracket 8, abutting against the slide rail 601. The pulley 9 can slide along the length of the slide rail 601. The slide rail 601 is provided on the support member 6, and the pulley 9 is supported by the slide rail 601. The pulley 9 slides on the slide rail 601, driving the bracket 8 to move.

[0041] In one embodiment, the purge assembly 7 is rotatably connected to the bracket 8 via a rotary joint 16. The rotary joint 16 can rotate relative to the bracket 8. During use, the gas compressor delivers high-pressure gas to the purge assembly 7. Since the high-pressure gas has a certain pressure, during the process of purging the high-pressure gas, the rotary joint 16 is driven by the high-pressure gas to rotate around its axis, thereby driving the purge assembly 7 to rotate. This can increase the purge range of the purge assembly 7. Even when a small number of purge assemblies 7 are provided, various parts of the cover groove 101 can be purged, which helps to save the manufacturing cost of the cover groove cleaning tool. In addition, by driving the purge assembly 7 to rotate via the rotary joint 16, the purge angle of the purge assembly 7 can be changed, accelerating the removal of adhesives from the inside of the cover groove 101 and improving the cleaning effect. Of course, in other embodiments, the purge assembly 7 can also be fixedly connected to the bracket 8.

[0042] The purge assembly 7 includes a high-pressure nozzle 701 and a connecting pipe 702 connected to the gas compressor. One end of the connecting pipe 702 is connected to the rotary joint 16. The high-pressure nozzle 701 is arranged at the end of the connecting pipe 702 away from the bracket 8. The high-pressure nozzle 701 is used to distribute high-pressure gas to purge the adhesive inside the covering groove 101.

[0043] Preferably, the purge assembly 7 includes two high-pressure nozzles 701, which are spaced apart in the vertical direction. By increasing the number of high-pressure nozzles 701, the purge range can be expanded, preventing the existence of a purge blind spot in the cover groove 101. In this example, the number of high-pressure nozzles 701 can be flexibly changed as needed, and there is no specific limitation on the number of high-pressure nozzles 701.

[0044] In one embodiment of the cover groove cleaning tool, the air flow of the high-pressure nozzle 701 is controlled by a control assembly, which includes a control valve 11 and a sensing component. The control valve 11 is closed or opened by the sensing component, which includes a sensor switch 12 and a sensor plate (not shown) that senses the sensor switch 12. The sensor switch 12 is positioned between the first end of the slide rail 601 and the bracket 8. The sensor plate is mounted on the bracket 8 and is in communication with the control valve 11. The sensor plate moves synchronously with the bracket 8. When the bracket 8 moves toward the first end to a set position, the sensor plate senses the sensor switch 12. The sensor switch 12 controls the high-pressure nozzle 701 to spray air through the control valve 11, thereby purging the cover groove 101. When the bracket 8 moves toward the second end, the sensor plate loses its sense of the sensor switch 12, and the sensor switch 12 shuts off the high-pressure nozzle 701 through the control valve 11, stopping the purging operation. In this embodiment, when the bracket 8 is in the set position, the horizontal distance between the purge assembly 7 and the valve seat 2 is 50 mm. In other examples, the setting position can be flexibly selected as needed.

[0045] In this embodiment, the bottom of bracket 8 is provided with a protrusion 801 protruding toward support member 6. Pulley 9 is located on the side of the protrusion closest to slide rail 601, and the sensor plate is located on the side of protrusion 801 facing away from counterweight 4. The provision of protrusion 801 provides a mounting location for the sensor plate and pulley 9. In this embodiment, protrusion 801 serves as a reinforcement beam, which enhances the structural strength of bracket 8.

[0046] During specific implementation, an air supply pipe is fixedly provided on the bracket 8, one end of the air supply pipe is connected to the connecting pipe 702 through a rotary joint 16, and the other end is connected to the gas compressor through an air supply pipe 14, and a control valve 11 is provided on the air supply pipe 14. In order to prevent the gas compressor from supplying air to the purge assembly 7 during the movement of the bracket 8 on the support 6, the air supply pipe 14 is provided as a hose. Preferably, the air supply pipe 14 is a corrugated pipe. By providing the air supply pipe 14 as a hose, the position of the air supply pipe 14 can also be changed or the air supply pipe 14 can be extended or retracted during the movement of the bracket 8, so that the air supply pipe 14 can adapt to the movement of the bracket 8. In other examples, the control valve 11 can also be provided on the air supply pipe or the connecting pipe 702.

[0047] In this embodiment, the air supply pipe and the bracket 8 are integrally provided, so that the air supply pipe can both deliver gas and support the purge assembly 7. In other embodiments, the air supply pipe and the bracket 8 can also be provided separately.

[0048] In order to facilitate monitoring whether the adhesive in the covering groove 101 is cleaned, a monitoring component 15 is provided on the top of the bracket 8, and the monitoring component 15 is used to monitor the covering groove 101 and the valve port. The monitoring component 15 is located above the high-pressure nozzle 701 and above the valve seat. In this embodiment, the monitoring component 15 is a camera. During specific implementation, the monitoring component 15 is connected to the terminal device for communication, and the covering groove 101 is photographed by the monitoring device, and the video or photo is transmitted to the terminal device. The user can observe whether there is adhesive inside the covering groove 101 in the terminal device. When there is no adhesive in the covering groove 101, the purge component 7 stops purging. When there is adhesive in the covering groove 101, the purge component 7 continues to purge the covering groove 101. In addition, the exhaust condition of the valve port can also be observed through the monitoring component 15.

[0049] In another embodiment, a method for cleaning a cover groove is provided, which includes a cover groove cleaning tool having the dispersing device according to any of the above embodiments, and comprises the following steps:

[0050] Step S10: Open the valve cover 1 of the dispersion device, and at the same time, the traction assembly 5 pulls the bracket 8 toward the valve seat 2 to a set position. During the specific operation, the driving member 3 of the dispersion device is used to drive the valve cover 1 to flip so that the valve cover 1 forms a first angle α with the horizontal plane. In this embodiment, 0°<α<180°. Preferably, α=90°. When the first angle α is 90°, the high-pressure gas purged horizontally by the purge assembly 7 is perpendicular to the cover groove 101, and the purge effect on the cover groove 101 is optimal at this time.

[0051] Step S20: Use the purge assembly 7 to purge the capping groove 101 on the valve cover 1 for a set period of time.

[0052] Step S30 , using the monitoring component 15 to monitor the inside of the covering groove 101 , if there is no adhesive in the covering groove 101 , the purge assembly 7 stops purging, if there is adhesive in the covering groove 101 , repeating step S20 .

[0053] In this method of cleaning the covering groove, when the valve cover 1 is opened, the high-pressure gas can be automatically purged into the covering groove 101 on the valve cover 1 through the purge component 7 to clean the adhesive inside the covering groove 101. There is no need for the operator to climb to the top of the blast furnace to clean the covering groove 101. It has the characteristics of low labor intensity and high safety.

[0054] Step S20 specifically includes step S21: After the purge assembly 7 purges the capping groove 101 for a first time period T1, the purge assembly 7 stops purge. After a second time period T2, the purge assembly 7 continues to purge the capping groove 101 for the first time period T1. Specifically, T1 = 5 seconds, and T2 = 5 seconds. This purge of the capping groove 101 by the purge assembly 7 can change the force applied to the adhesive within the capping groove 101, further facilitating its removal from the capping groove 101.

[0055] Preferably, while the purge assembly 7 is performing the purge, the purge assembly 7 rotates around the axis of the rotary joint 16 .

[0056] In specific implementation, in step S20, the purge component 7 purges the cover groove 101 on the valve cover 1 for 5-10 minutes, and then uses the monitoring component 15 to monitor the cover groove 101 through video or photos to determine whether there is adhesive inside the cover groove 101.
