While making further fixation in the axial direction of the installation frame, it can also carry and install relevant components. The support part is arranged on one side of the first stay bar close to the axial direction of the installation frame to support the cleaning component inside the installation frame. The driving component is arranged on one side of the first stay bar close to the axial direction of the installation frame. Setting the driving component inside the installation frame can save installation space.

When the arc furnace tail slag cleaning device operates, the driving component can drive the cleaning component to move along the axial direction of the installation frame, so that the cleaning component can extend into the flue of the furnace tail of the arc furnace and clean the inner wall.

[0007] This technical solution provides an arc furnace tail slag cleaning device. In addition to the technical features of the above technical solution, this technical solution further includes the following technical features.

[0008] The cleaning component includes a traveling part and a cleaning part. The traveling part extends along the axial direction of the installation frame and abuts against one side of the support part close to the axial direction of the installation frame. The cleaning part is arranged on the traveling part and protrudes outside the installation frame. The outer diameter of the cleaning part is larger than the outer diameter of the traveling part.

[0009] In this technical solution, the cleaning assembly includes a traveling portion and a cleaning portion. The traveling portion extends along the axial direction of the mounting frame and can reciprocate in the axial direction of the mounting frame. The traveling portion abuts against the side of the support portion close to the axial direction of the mounting frame.

[0012] In this technical solution, the cleaning component also includes a limiting part, which is used to limit the travel of the traveling part and the cleaning part. The limiting part is sleeved on the traveling part and is located between the mounting frame and the cleaning part. When the arc furnace tail slag cleaning device is working, the limiting part is pressed against the outer end of the flue at the tail of the arc furnace. When the cleaning part extends into the flue at the tail of the arc furnace, the limiting part can limit the end of the traveling part away from the cleaning part, thereby preventing the traveling part from being out of control of the driving component due to excessive movement stroke, and ensuring that the traveling part will not fall off from the mounting frame and cause damage. When the cleaning part leaves the flue at the tail of the arc furnace, the limiting part can limit the cleaning part, thereby preventing the cleaning part from shrinking into the mounting frame due to excessive movement stroke, causing hard collision with related components and causing damage, further ensuring the normal operation of the arc furnace tail slag cleaning device.

[0013] The present technical solution provides an electric arc furnace tail slag cleaning device. In addition to the technical features of the above-mentioned technical solution, the present technical solution further includes the following technical features.

A third cavity is provided inside the cleaning body, and the third cavity inside the cleaning body can provide a containment space for the heat exchange medium. The cleaning body is connected to one end of the traveling part and can move synchronously with the traveling part. The cleaning ribs are arranged along the circumferential direction of the cleaning body and protrude from the cleaning body. When the cleaning part enters the flue of the furnace tail of the electric arc furnace, the inner wall of the flue of the furnace tail of the electric arc furnace and the generated debris come into contact with the cleaning part, and the inner wall of the flue is cleaned by the cleaning ribs, avoiding the direct contact between the cleaning body and the inner wall of the flue of the furnace tail of the electric arc furnace, reducing the loss of the cleaning part during operation, and thus improving the operating efficiency of the slag cleaning device for the electric arc furnace tail.

A first water outlet joint is arranged on the second push rod, and the first water outlet joint is connected to the second cavity; wherein, the third cavity is respectively connected to the first cavity and the second cavity, and the heat exchange medium can enter the second cavity from the first cavity via the third cavity.

[0018] In this technical solution, the traveling part includes a first push rod and a second push rod. A first cavity is provided inside the first push rod, which can provide a containment space for the heat exchange medium. A first water inlet joint is arranged on the first push rod, and the first water inlet joint is connected to the first cavity, enabling the heat exchange medium to circulate inside and outside the first cavity through the first water inlet joint. One end of the first push rod is hermetically connected to the cleaning body, so that when the heat exchange medium flows between the first cavity and the third cavity, no leakage occurs. A second cavity is provided inside the second push rod, which can provide a containment space for the heat exchange medium.

Wherein, the third cavity is respectively connected to the first cavity and the second cavity, and the heat exchange medium can enter the second cavity from the first cavity via the third cavity. Through the circulation of the heat exchange medium between the first cavity, the third cavity and the second cavity, the heat on the cleaning part can be taken away to cool down the cleaning part, avoiding other losses such as melting of the cleaning part caused by the excessively high temperature inside the flue of the furnace tail of the electric arc furnace, and thus improving the operating efficiency of the slag cleaning device for the electric arc furnace tail.

[0019] This technical solution provides an electric arc furnace tail slag cleaning device. In addition to the technical features of the above technical solution, this technical solution further includes the following technical features.

[0020] The second stay bar includes a flexible tube, a second water outlet joint and a second water inlet joint. The flexible tube is arranged on the second stay bar; the second water outlet joint is arranged at the first end of the second stay bar and is connected to the first water inlet joint through the flexible tube; the second water inlet joint is arranged at the first end of the second stay bar and is connected to the first water outlet joint through the flexible tube. Among them, the second water outlet joint inputs the heat exchange medium into the first cavity through the first water inlet joint, and the second cavity outputs the heat exchange medium to the second water inlet joint through the first water outlet joint.

[0021] In this technical solution, the second stay bar includes a flexible tube, a second water outlet joint and a second water inlet joint. The flexible tube is arranged on the second stay bar, and the second stay bar bears the gravity generated by the flexible tube and its connected components. The second stay bar can also bear the axial force on the mounting frame, further ensuring the stability of the mounting frame. The second water outlet joint is arranged at the first end of the second stay bar and is connected to the first water inlet joint through the flexible tube, enabling the heat exchange medium to flow between the second water outlet joint and the first water inlet joint. The second water inlet joint is arranged at the first end of the second stay bar and is connected to the first water outlet joint through the flexible tube, enabling the heat exchange medium to flow between the second water inlet joint and the first water outlet joint. The second water outlet joint inputs the heat exchange medium into the first cavity through the first water inlet joint, and the second cavity outputs the heat exchange medium to the second water inlet joint through the first water outlet joint. When the electric arc furnace tail slag cleaning device works, the heat exchange medium flows from the second water outlet joint through the flexible tube to the first water inlet joint, enters the first cavity, flows into the second cavity after passing through the third cavity, and flows out from the first water outlet joint, and flows through the flexible tube to the second water inlet joint, thus completing the cooling cycle of the cleaning component, reducing the temperature of the cleaning part, and further avoiding other losses such as melting of the cleaning part caused by the excessive temperature inside the flue at the tail of the electric arc furnace, thereby improving the operating efficiency of the electric arc furnace tail slag cleaning device. The flexible tube can adapt to the movement of the first push rod and the second push rod by generating deformation, so as to ensure that the cleaning component can still obtain a good cooling cycle effect during operation.

[0022] Furthermore, the flexible tube can be formed by cooperating with a cable carrier. The hose is arranged in the cable carrier, and one end of the cable carrier is connected to the first transmission part, enabling the hose to move synchronously with the first push rod and the second push rod and being protected at the same time, extending its service life.

[0023] Furthermore, the two side edges of the second stay bar parallel to the axis of the mounting frame can be turned up to form through grooves, and the other end of the cable carrier is fixed in the through grooves, which can use the through grooves to limit the lateral displacement of the cable carrier and prevent the cable carrier from falling off the second stay bar.

[0024] This technical solution provides a slag cleaning device for the arc furnace tail. In addition to the technical features of the above technical solution, this technical solution further includes the following technical features.

[0025] The limiting part includes a plate body, a limiting sleeve and a cover body. The outer diameter of the plate body is larger than the inner diameter of the installation frame; the limiting sleeve is arranged on the side of the plate body close to the installation frame, and the first push rod and the second push rod respectively penetrate through the limiting sleeve, and the limiting sleeve extends towards the direction close to the installation frame; the first end of the cover body is fixedly connected to the plate body, and the inner diameter of the second end of the cover body is larger than the outer diameter of the cleaning part.

[0026] In this technical solution, the limiting part includes a plate body, a limiting sleeve and a cover body. The outer diameter of the plate body is larger than the inner diameter of the installation frame, which limits the cleaning part to ensure that during the retraction process of the cleaning part, it will not collide hard with the relevant components inside the installation frame due to excessive retraction stroke, thus causing damage. The limiting sleeve is arranged on the side of the plate body close to the installation frame to avoid occupying the movement space of the cleaning part. The first push rod and the second push rod respectively penetrate through the limiting sleeve, and the limiting sleeve extends towards the direction close to the installation frame. By sleeving the extended part on the first push rod and the second push rod, the limiting sleeve can limit the displacement of the plate body in the radial direction of the cleaning part to avoid the movement direction of the cleaning part from deviating due to uneven force exerted by the plate body on the first push rod and the second push rod, thereby increasing the risk of loss of relevant components and affecting the working efficiency of the slag cleaning device for the arc furnace tail. The first end of the cover body is fixedly connected to the plate body, and the inner diameter of the second end of the cover body is larger than the outer diameter of the cleaning part. When the cleaning part is in the retracted state, the cover body can protect the cleaning part. When the slag cleaning device for the arc furnace tail starts to work, the second end of the cover body is abutted against the outer end of the flue of the arc furnace tail, so that a closed space is formed between the plate body and the flue of the arc furnace tail. The cleaning part can reciprocate in this closed space to clean the flue of the arc furnace tail, while avoiding the debris in the flue of the arc furnace tail from splashing and hurting people due to collision, and at the same time reducing the pollution to the surrounding environment.

[0027] Furthermore, the cleaning part further includes a buffer member. The buffer member is arranged at one end of the cleaning body close to the plate body, and the buffer member coincides with the axis of the limiting sleeve. By setting the buffer member, the impact of the cleaning part on the plate body during the retraction process is reduced, thereby reducing the vibration generated during the operation of the slag cleaning device for the arc furnace tail, reducing the loss between relevant components, and increasing the service life of the slag cleaning device for the arc furnace tail.

[0028] Further, the cleaning body is annular, and limiting bumps are provided on the plate body. The axis of the cleaning body coincides with that of the limiting bumps, and the outer diameter of the limiting bumps is smaller than the inner diameter of the cleaning body. By providing the limiting bumps that cooperate with the cleaning body, it is avoided that the movement direction of the cleaning part does not deviate during the retraction process, so that the cleaning part can be in the correct initial position before the next extension and advancement.

[0030] The advancing part further includes a first transmission part, and the first transmission part is arranged on the first push rod; or the first transmission part is arranged on the second push rod, and the first transmission part is in transmission connection with the driving component.

[0031] In this technical solution, the advancing part further includes a first transmission part, and the first transmission part is used to drive the advancing part to move. The first transmission part can be arranged on the first push rod, and the first transmission part is in transmission connection with the driving component. When the slag cleaning device for the tail of the electric arc furnace starts to work, the driving component drives the first transmission part to move, and the first transmission part drives the first push rod to move, and then drives the cleaning part to move. The first transmission part can also be arranged on the second push rod, and the first transmission part is in transmission connection with the driving component. When the slag cleaning device for the tail of the electric arc furnace starts to work, the driving component drives the first transmission part to move, and the first transmission part drives the second push rod to move, and then drives the cleaning part to move.

[0032] This technical solution provides a slag cleaning device for the tail of an electric arc furnace. In addition to the technical features of the above technical solution, this technical solution further includes the following technical features.

[0033] The driving component includes a driving part and a second transmission part. The driving part is arranged on the installation frame; the input end of the second transmission part is connected to the output end of the driving part, and the output end of the second transmission part is connected to the first transmission part; wherein, the first transmission part can drive the advancing part to move relative to the second transmission part.

[0034] In this technical solution, the driving component includes a driving part and a second transmission part. The driving part is arranged on the installation frame and is used to provide power for the slag cleaning device for the tail of the electric arc furnace. The input end of the second transmission part is connected to the output end of the driving part to transmit the power generated by the driving part. The output end of the second transmission part is connected to the first transmission part, and the driving part can drive the first transmission part to move through the second transmission part. When the slag cleaning device for the tail of the electric arc furnace starts to work, there is no displacement between the second transmission part and the installation frame, and the first transmission part moves synchronously with the advancing part. Then, the first transmission part moves relative to the second transmission part.

[0035] Further, the first transmission part is a rack, the second transmission part is a gearbox, and the rack meshes with the output end of the gearbox so that the driving component drives the traveling part to move.

[0036] Further, the driving part is a hydraulic engine. By pushing the hydraulic engine to output power through a hydraulic station, parameters such as the running speed and running force of the hydraulic engine can be finely adjusted, making the operation process of the slag cleaning device at the end of the electric arc furnace smoother.

[0039] In this technical solution, the traveling part further includes a reinforcing rib, and both sides of the reinforcing rib are fixedly connected to the first push rod and the second push rod respectively. Setting the reinforcing rib between the first push rod and the second push rod can prevent the distance between the first push rod and the second push rod from becoming larger or smaller due to deformation, making the traveling part move more smoothly. Thus, the cleaning part can clean the flue at the end of the electric arc furnace under a more stable and accurate working condition, thereby increasing the work efficiency and reducing the wear of components.

Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0053] Next, refer to Figures 1 to 7 Describe the electric arc furnace tail slag cleaning device according to some embodiments of the present utility model.

[0054] ]>As Figure 1 、 Figure 2 And Figure 3As shown in the figure, in an embodiment of the present utility model, a slag cleaning device 10 for an electric arc furnace tail is provided, which includes an installation frame 100, a driving component 200 and a cleaning component 300. The installation frame 100 includes a first stay 110, a second stay 120 and a support portion 130. The first stay 110 is arranged on the installation frame 100, the second stay 120 is arranged on the first stay 110 and extends along the axial direction of the installation frame 100, and the support portion 130 is arranged on one side of the first stay 110 close to the axial direction of the installation frame 100; the driving component 200 is arranged on one side of the first stay 110 close to the axial direction of the installation frame 100; the cleaning component 300 is arranged on the support portion 130 and is in transmission connection with the driving component 200; wherein, the driving component 200 can drive the cleaning component 300 to move along the axial direction of the installation frame 100.

[0055] As Figure 1 , Figure 2 and Figure 3As shown, the present application provides an arc furnace tail slag cleaning device 10, including a mounting frame 100, a drive assembly 200 and a cleaning assembly 300. The mounting frame 100 is used to carry the installation of related components and make the related components at a height corresponding to the arc furnace tail. The mounting frame 100 includes a first tie bar 110, a second tie bar 120 and a support portion 130. The first tie bar 110 is arranged on the mounting frame 100, which can not only maintain the structural stability of the mounting frame 100, but also carry and install the weight of related components. The second tie bar 120 is arranged on the first tie bar 110, extending along the axial direction of the mounting frame 100, and is installed in the mounting frame 100. While further fixing the mounting frame 100 in the axial direction, the relevant components can also be carried and installed. The support portion 130 is arranged on the axial side of the first tie rod 110 close to the mounting frame 100, and supports the cleaning assembly 300 inside the mounting frame 100. The drive assembly 200 is arranged on the axial side of the first tie rod 110 close to the mounting frame 100. Setting the drive assembly 200 inside the mounting frame 100 can save installation space. The cleaning assembly 300 is arranged on the support portion 130 and is connected to the drive assembly 200 in a transmission connection, so that the drive assembly 200 can drive the cleaning assembly 300 to move through the transmission connection. When the arc furnace tail slag cleaning device 10 is in operation, the drive assembly 200 can drive the cleaning assembly 300 to move along the axial direction of the mounting frame 100, so that the cleaning assembly 300 can extend into the flue of the arc furnace tail and clean the inner wall. By arranging the driving assembly 200 and the cleaning assembly 300 in the mounting frame 100, the inside of the flue at the tail of the arc furnace can be automatically cleaned while the arc furnace maintains operation and production. There is no need to manually clean the inside of the flue at the tail of the arc furnace using tools, which avoids the accumulation and blockage of the flue at the tail of the arc furnace by debris generated during the operation of the arc furnace, and thus the arc furnace will not be shut down due to blockage of the flue at the tail of the arc furnace during the operation of the arc furnace, thereby improving the energy utilization efficiency and reducing the labor intensity of relevant personnel.

[0056] Specifically, if Figure 1 As shown, the axial direction of the mounting frame is direction D.

[0057] Specifically, if Figure 2 As shown, the axial side of the first reinforcement close to the mounting frame is F.

[0058] This embodiment provides an electric arc furnace tail slag cleaning device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0059] like Figure 1 and Figure 2As shown, the cleaning assembly 300 includes a traveling portion 310 and a cleaning portion 330. The traveling portion 310 extends along the axial direction of the mounting frame 100 and abuts against the axial side of the support portion 130 close to the mounting frame 100. The cleaning portion 330 is arranged on the traveling portion 310 and protrudes outside the mounting frame 100. The outer diameter of the cleaning portion 330 is larger than the outer diameter of the traveling portion 310.

[0060] like Figure 1 and Figure 2 As shown, in this embodiment, the cleaning assembly 300 includes a traveling portion 310 and a cleaning portion 330. The traveling portion 310 extends along the axial direction of the mounting frame 100 and can reciprocate in the axial direction of the mounting frame 100. The traveling portion 310 abuts against the axial side of the support portion 130 close to the mounting frame 100. When the traveling portion 310 is stationary, the support portion 130 bears the weight of the traveling portion 310 and supports it. When the traveling portion 310 moves, the traveling portion 310 can move relative to the support portion 130; the cleaning portion 330 is arranged on the traveling portion 310 and protrudes from the outside of the mounting frame 100. When the traveling portion 310 reciprocates, it can drive the cleaning portion 330 to reciprocate together, thereby sending the cleaning portion 330 into the flue at the tail of the electric arc furnace and cleaning its inner wall to prevent accumulation of debris. The outer diameter of the cleaning portion 330 is larger than that of the traveling portion 310 , which can prevent the traveling portion 310 from contacting the inner wall of the flue at the tail of the electric arc furnace and causing damage, thereby ensuring the normal operation of the electric arc furnace tail slag cleaning device 10 .

[0061] Specifically, if Figure 3 As shown, the axial side of the support portion close to the mounting frame is G.

[0062] This embodiment provides an electric arc furnace tail slag cleaning device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0063] like Figure 1 and Figure 2 As shown, the cleaning assembly 300 further includes a limiting portion 340 , which is sleeved on the traveling portion 310 and located between the mounting frame 100 and the cleaning portion 330 .

[0064] like Figure 1 and Figure 2As shown, in this embodiment, the cleaning component 300 further includes a limiting portion 340 for limiting the travel of the traveling portion 310 and the cleaning portion 330. The limiting portion 340 is sleeved on the traveling portion 310 and is located between the mounting frame 100 and the cleaning portion 330. When the slag cleaning device 10 at the tail of the electric arc furnace works, the limiting portion 340 is abutted against the outer end of the flue at the tail of the electric arc furnace. When the cleaning portion 330 extends into the flue at the tail of the electric arc furnace, the limiting portion 340 can limit one end of the traveling portion 310 away from the cleaning portion 330, preventing the traveling portion 310 from getting out of control of the driving component 200 due to excessive travel and ensuring that the traveling portion 310 does not fall off the mounting frame 100, thus avoiding damage. When the cleaning portion 330 leaves the flue at the tail of the electric arc furnace, the limiting portion 340 can limit the cleaning portion 330, preventing the cleaning portion 330 from contracting into the mounting frame 100 due to excessive travel and colliding hard with related components, further ensuring the normal operation of the slag cleaning device 10 at the tail of the electric arc furnace.

[0065] This embodiment provides a slag cleaning device 10 at the tail of an electric arc furnace. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0066] As Figure 1 、 Figure 2 and Figure 4 shown, the cleaning portion 330 includes a cleaning body 332 and cleaning ribs 334. A third cavity 336 is provided inside the cleaning body 332, and it is connected to one end of the traveling portion 310; the cleaning ribs are arranged circumferentially along the cleaning body 332 and protrude from the cleaning body 332.

[0067] As Figure 1 、 Figure 2 and Figure 4 shown, in this embodiment, the cleaning portion 330 includes a cleaning body 332 and cleaning ribs 334. A third cavity 336 is provided inside the cleaning body 332. The third cavity 336 inside the cleaning body 332 can provide a space for accommodating the heat exchange medium. The cleaning body 332 is connected to one end of the traveling portion 310 and can move synchronously with the traveling portion 310. The cleaning ribs 334 are arranged circumferentially along the cleaning body 332 and protrude from the cleaning body 332. When the cleaning portion 330 enters the flue at the tail of the electric arc furnace, the inner wall of the flue at the tail of the electric arc furnace and the generated debris come into contact with the cleaning portion 330, and the cleaning ribs 334 clean the inner wall of the flue, preventing the cleaning body 332 from directly contacting the inner wall of the flue at the tail of the electric arc furnace, reducing the loss of the cleaning portion 330 during operation, and thus improving the operating efficiency of the slag cleaning device 10 at the tail of the electric arc furnace.

[0068] Specifically, as Figure 4 shown, the circumferential direction of the cleaning body is direction E.

[0069] This embodiment provides an arc furnace tail slag cleaning device 10. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0070] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the traveling part 310 includes a first push rod 314 and a second push rod 320. A first cavity 316 is provided inside the first push rod 314. A first water inlet joint 318 is arranged on the first push rod 314, and the first water inlet joint 318 is communicated with the first cavity 316. One end of the first push rod 314 is hermetically connected to the cleaning body 332; a second cavity 322 is provided inside the second push rod 320. A first water outlet joint 324 is arranged on the second push rod 320, and the first water outlet joint 324 is communicated with the second cavity 322; wherein, a third cavity 336 is respectively communicated with the first cavity 316 and the second cavity 322, and the heat exchange medium can enter the second cavity 322 from the first cavity 316 via the third cavity 336.

[0071] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, the traveling part 310 includes a first push rod 314 and a second push rod 320. A first cavity 316 is provided inside the first push rod 314, which can provide a containing space for the heat exchange medium. A first water inlet joint 318 is arranged on the first push rod 314, and the first water inlet joint 318 is connected to the first cavity 316, enabling the heat exchange medium to flow in and out of the first cavity 316 through the first water inlet joint 318. One end of the first push rod 314 is hermetically connected to the cleaning body 332, so that when the heat exchange medium flows between the first cavity 316 and the third cavity 336, no leakage will occur. A second cavity 322 is provided inside the second push rod 320, which can provide a containing space for the heat exchange medium. A first water outlet joint 324 is arranged on the second push rod 320, and the first water outlet joint 324 is connected to the second cavity 322, enabling the heat exchange medium to flow in and out of the second cavity 322 through the first water outlet joint 324. One end of the second push rod 320 is hermetically connected to the cleaning body 332, so that when the heat exchange medium flows between the second cavity 322 and the third cavity 336, no leakage will occur. Among them, the third cavity 336 is respectively connected to the first cavity 316 and the second cavity 322, and the heat exchange medium can enter the second cavity 322 from the first cavity 316 via the third cavity 336. Through the circulation of the heat exchange medium between the first cavity 316, the third cavity 336 and the second cavity 322, the heat on the cleaning part 330 can be taken away, cooling the cleaning part 330, and avoiding other losses such as melting caused by the excessive temperature inside the flue at the tail of the electric arc furnace, thereby improving the operating efficiency of the slag cleaning device 10 at the tail of the electric arc furnace.

[0072] This embodiment provides a slag cleaning device 10 at the tail of an electric arc furnace. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0073] As Figure 6 shown, the second stay bar 120 includes a flexible tube 122, a second water outlet joint 124 and a second water inlet joint 126. The flexible tube 122 is arranged on the second stay bar 120; the second water outlet joint 124 is arranged at the first end of the second stay bar 120 and is connected to the first water inlet joint 318 through the flexible tube 122; the second water inlet joint 126 is arranged at the first end of the second stay bar 120 and is connected to the first water outlet joint 324 through the flexible tube 122. Among them, the second water outlet joint 124 inputs the heat exchange medium into the first cavity 316 through the first water inlet joint 318, and the second cavity 322 outputs the heat exchange medium to the second water inlet joint 126 through the first water outlet joint 324.

[0074] As Figure 6As shown, in this embodiment, the second tension bar 120 includes a flexible tube 122, a second water outlet joint 124, and a second water inlet joint 126. The flexible tube 122 is disposed on the second tension bar 120, and the second tension bar 120 bears the gravity generated by the flexible tube 122 and its connected components. The second tension bar 120 can also bear the axial force received by the mounting frame 100, further ensuring the stability of the mounting frame 100. The second water outlet joint 124 is disposed at the first end of the second tension bar 120 and is connected to the first water inlet joint 318 through the flexible tube 122, enabling the heat exchange medium to flow between the second water outlet joint 124 and the first water inlet joint 318. The second water inlet joint 126 is disposed at the first end of the second tension bar 120 and is connected to the first water outlet joint 324 through the flexible tube 122, enabling the heat exchange medium to flow between the second water inlet joint 126 and the first water outlet joint 324. The second water outlet joint 124 inputs the heat exchange medium into the first cavity 316 through the first water inlet joint 318, and the second cavity 322 outputs the heat exchange medium to the second water inlet joint 126 through the first water outlet joint 324. When the electric arc furnace tail slag cleaning device 10 operates, the heat exchange medium flows from the second water outlet joint 124 through the flexible tube 122 to the first water inlet joint 318, enters the first cavity 316, flows into the second cavity 322 after passing through the third cavity 336, and flows out from the first water outlet joint 324, and flows through the flexible tube 122 to the second water inlet joint 126, thereby completing the cooling cycle of the cleaning component 300, reducing the temperature of the cleaning part 330, and further avoiding other losses such as melting of the cleaning part 330 caused by excessive temperature inside the flue at the tail of the electric arc furnace, and further improving the operating efficiency of the electric arc furnace tail slag cleaning device 10. The flexible tube 122 can adapt to the movement of the first push rod 314 and the second push rod 320 by generating deformation, so as to ensure that the cleaning component 300 can still obtain a good cooling cycle effect during operation.

[0075] Further, the flexible tube 122 can be formed by cooperating a hose with a drag chain. The hose is disposed in the drag chain, and one end of the drag chain is connected to the first transmission part 312, enabling the hose to move synchronously with the first push rod 314 and the second push rod 320 and being protected, thus extending the service life.

[0076] Further, the two side edges of the second tension bar 120 parallel to the axis of the mounting frame 100 can be turned up to form through grooves, and the other end of the drag chain is fixed in the through grooves, which can use the through grooves to limit the lateral displacement of the drag chain and prevent the drag chain from falling off the second tension bar 120.

[0077] Specifically, as Figure 7 shown, the first end of the second tension bar is A.

[0078] This embodiment provides an arc furnace tail slag cleaning device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0079] As Figure 1 , Figure 2 and Figure 4 shown, the limiting part 340 includes a plate body 342, a limiting sleeve 344 and a cover body 346. The outer diameter of the plate body 342 is larger than the inner diameter of the installation frame 100; the limiting sleeve 344 is arranged on the side of the plate body 342 close to the installation frame 100, and the first push rod 314 and the second push rod 320 respectively penetrate through the limiting sleeve 344, and the limiting sleeve 344 extends towards the direction close to the installation frame 100; the first end of the cover body 346 is fixedly connected to the plate body 342, and the inner diameter of the second end of the cover body 346 is larger than the outer diameter of the cleaning part 330.

[0080] As Figure 1 , Figure 2 and Figure 4 shown, in this embodiment, the limiting part 340 includes a plate body 342, a limiting sleeve 344 and a cover body 346. The outer diameter of the plate body 342 is larger than the inner diameter of the installation frame 100 to limit the cleaning part 330, so as to ensure that during the retraction process of the cleaning part 330, it will not collide hard with the relevant components inside the installation frame 100 due to excessive retraction stroke, thus causing damage. The limiting sleeve 344 is arranged on the side of the plate body 342 close to the installation frame 100 to avoid occupying the movement space of the cleaning part 330. The first push rod 314 and the second push rod 320 respectively penetrate through the limiting sleeve 344, and the limiting sleeve 344 extends towards the direction close to the installation frame 100. The limiting sleeve 344 can limit the displacement of the plate body 342 in the radial direction of the cleaning part 330 by sleeving the extended part on the first push rod 314 and the second push rod 320, so as to avoid the movement direction of the cleaning part 330 being offset due to uneven force exerted by the plate body 342 on the first push rod 314 and the second push rod 320, thereby increasing the risk of loss of relevant components and affecting the working efficiency of the arc furnace tail slag cleaning device 10. The first end of the cover body 346 is fixedly connected to the plate body 342, and the inner diameter of the second end of the cover body 346 is larger than the outer diameter of the cleaning part 330. When the cleaning part 330 is in the retracted state, the cover body 346 can protect the cleaning part 330. When the arc furnace tail slag cleaning device 10 starts to work, the second end of the cover body 346 is abutted against the outer end of the flue of the arc furnace tail, so as to form a closed space between the plate body 342 and the flue of the arc furnace tail. The cleaning part 330 can reciprocate in this closed space to clean the flue of the arc furnace tail, while avoiding the sundries in the flue of the arc furnace tail from splashing and hurting people due to collision, and reducing the pollution to the surrounding environment at the same time.

[0081] Specifically, as Figure 1 shown, the first end of the cover body is B.

[0082] Specifically, as Figure 1 shown, the first end of the cover body is C.

[0083] Specifically, as Figure 4 shown, the side of the plate body close to the mounting frame is H.

[0084] Specifically, as Figure 4 shown, the direction in which the limiting sleeve approaches the mounting frame is direction J.

[0085] Furthermore, the cleaning part 330 further includes a buffer member. The buffer member is disposed at one end of the cleaning body 332 close to the plate body 342. The buffer member coincides with the axis of the limiting sleeve 344. By providing the buffer member, the impact of the cleaning part 330 on the plate body 342 during the retraction process is reduced, thereby reducing the vibration generated during the operation of the electric arc furnace tail slag cleaning device 10, reducing the loss between related components, and increasing the service life of the electric arc furnace tail slag cleaning device 10.

[0086] Furthermore, the cleaning body 332 is annular. A limiting convex block is provided on the plate body 342. The axis of the cleaning body 332 coincides with that of the limiting convex block. The outer diameter of the limiting convex block is smaller than the inner diameter of the cleaning body 332. By providing the limiting convex block that cooperates with the cleaning body 332, it is avoided that the movement direction of the cleaning part 330 does not deviate during the retraction process, so that the cleaning part 330 can be in the correct initial position before the next extension and advancement.

[0087] This embodiment provides an electric arc furnace tail slag cleaning device 10. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0088] As Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, the traveling part 310 further includes a first transmission part 312. The first transmission part 312 is disposed on the first push rod 314; or the first transmission part 312 is disposed on the second push rod 320, and the first transmission part 312 is in transmission connection with the driving component 200.

[0089] As Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in this embodiment, the traveling part 310 further includes a first transmission part 312. The first transmission part 312 is used to drive the traveling part 310 to move. The first transmission part 312 can be arranged on the first push rod 314. The first transmission part 312 is in transmission connection with the driving component 200. When the slag cleaning device 10 at the tail of the electric arc furnace starts to work, the driving component 200 drives the first transmission part 312 to move, and the first transmission part 312 drives the first push rod 314 to move, thereby driving the cleaning part 330 to move. The first transmission part 312 can also be arranged on the second push rod 320. The first transmission part 312 is in transmission connection with the driving component 200. When the slag cleaning device 10 at the tail of the electric arc furnace starts to work, the driving component 200 drives the first transmission part 312 to move, and the first transmission part 312 drives the second push rod 320 to move, thereby driving the cleaning part 330 to move.

[0090] This embodiment provides a slag cleaning device 10 at the tail of an electric arc furnace. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0091] As Figure 1 and Figure 2 shown, the driving component 200 includes a driving part 210 and a second transmission part 220. The driving part 210 is arranged on the installation frame 100; the input end of the second transmission part 220 is connected to the output end of the driving part 210, and the output end of the second transmission part 220 is connected to the first transmission part 312; wherein, the first transmission part 312 can drive the traveling part 310 to move relative to the second transmission part 220.

[0092] As Figure 1 and Figure 2 shown, in this embodiment, the driving component 200 includes a driving part 210 and a second transmission part 220. The driving part 210 is arranged on the installation frame 100 and is used to provide power for the slag cleaning device 10 at the tail of the electric arc furnace. The input end of the second transmission part 220 is connected to the output end of the driving part 210 so as to transmit the power generated by the driving part 210. The output end of the second transmission part 220 is connected to the first transmission part 312. The driving part 210 can drive the first transmission part 312 to move through the second transmission part 220. When the slag cleaning device 10 at the tail of the electric arc furnace starts to work, there is no displacement between the second transmission part 220 and the installation frame 100, and the first transmission part 312 moves synchronously with the traveling part 310. Furthermore, the first transmission part 312 moves relative to the second transmission part 220.

[0093] Furthermore, the first transmission part 312 is a rack, and the second transmission part 220 is a gearbox. The rack meshes with the output end of the gearbox so as to enable the driving component 200 to drive the traveling part 310 to move.

[0094] Further, the driving unit 210 is a hydraulic engine. By pushing the hydraulic engine to output power through a hydraulic station, parameters such as the running speed and running force of the hydraulic engine can be finely adjusted, making the operation process of the electric arc furnace tail slag cleaning device 10 smoother.

[0095] This embodiment provides an electric arc furnace tail slag cleaning device 10. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

The two sides of the reinforcing rib 326 are respectively fixedly connected to the first push rod 314 and the second push rod 320. By arranging the reinforcing rib 326 between the first push rod 314 and the second push rod 320, it is possible to prevent the distance between the first push rod 314 and the second push rod 320 from becoming larger or smaller due to deformation, making the movement of the traveling part 310 smoother, so that the cleaning part 330 can clean the flue of the electric arc furnace tail in a more stable and accurate working condition, thereby improving work efficiency and reducing component wear.
