However, the process of draining residual iron requires workers to operate rock drills to create a drainage channel. During this process, the drained molten iron can easily splash, posing a risk to the safety of workers. Utility Model Content

[0055] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0056] like Figure 1 As shown, a residual iron tapping device 100 is provided according to a first aspect of the present disclosure, comprising: a rock drill 110 having a drill rod with a drill bit arranged toward a blast furnace 200; a transmission assembly 120, wherein the rock drill 110 is disposed on the transmission assembly 120, the transmission assembly 120 extending along a first direction and used to drive the rock drill 110 to move along the first direction; a pneumatic assembly 130 connected to the transmission assembly 120 and used to provide driving force to the transmission assembly 120; and a control assembly 140 connected to the pneumatic assembly 130 and used to control the output power of the pneumatic assembly 130; wherein the control assembly 140 is located away from the rock drill 110 and the transmission assembly 120.

[0057] The residual iron tapping device 100 according to the first aspect of this disclosure includes a rock drill 110, a transmission assembly 120, a pneumatic assembly 130, and a control assembly 140. The rock drill 110 is mounted on the transmission assembly 120 and has a drill rod with a drill bit facing the blast furnace 200. The pneumatic assembly 130 is connected to the transmission assembly 120 and provides power to the transmission assembly 120, thereby enabling the transmission assembly 120 to move the rock drill 110. In practical applications, the transmission assembly 120 extends along a first direction. Driven by the transmission assembly 120, the rock drill 110 can move along the first direction, and the drill bit on the drill rod moves towards the blast furnace 200, allowing the drill bit to pass through the blast furnace. Rock drilling operations are carried out on blast furnace 200. Driven by transmission component 120, the drill bit of rock drill 110 can open up a residual iron discharge channel on blast furnace 200 for residual iron discharge. In addition, control component 140 is connected to pneumatic component 130 and is located away from rock drill 110 and transmission component 120. Control component 140 can control the power output of pneumatic component 130. Workers can remotely control the power provided by pneumatic component 130 to transmission component 120 through control component 140 to control the movement of rock drill 110. That is, workers can observe and control the opening process of residual iron discharge channel from a location away from blast furnace 200, which is conducive to protecting the personal safety of workers.

[0058] It should be noted that in traditional techniques, workers often need to push the rock drill 110 to drill through the blast furnace 200 to create a channel for discharging residual iron. At the moment the channel is opened and during the process of the rock drill 110 exiting the channel, molten iron is prone to splashing. This splashed molten iron has a high temperature, posing a significant safety hazard and potentially causing injury to workers. Compared to traditional techniques, the residual iron discharge device 100 proposed in this embodiment, based on the aforementioned design, can provide greater driving force through pneumatic drive, making the progress control of the rock drill 110 more stable. Simultaneously, it allows for remote control of the rock drill 110's progress, preventing molten iron splashing from endangering workers' safety.

[0059] Understandably, the pneumatic assembly 130 can use a hose for gas transmission, which facilitates connection to the remote control assembly 140 and also allows for adjustments to the position of the control assembly 140.

[0060] In some examples, the pneumatic assembly 130 includes: a first pneumatic unit connected to the transmission assembly 120; a second pneumatic unit connected to the rock drill 110; and an air source unit, which is connected to both the first and second pneumatic units and is used to provide inert gas; wherein the control assembly 140 can control the first and second pneumatic units respectively.

[0061] In the above technical solution, the pneumatic component 130 includes a first pneumatic part, a second pneumatic part, and an air source part. The air source part is connected to the first pneumatic part and the second pneumatic part respectively. The air source part can provide inert gas as a power source for the first pneumatic part and the second pneumatic part. The first pneumatic part provides power to the transmission component 120, and the second pneumatic part provides power to the rock drill 110. At the same time, the control component 140 can control the first pneumatic part and the second pneumatic part respectively. That is, the control component 140 can control the drive of the rock drill 110 and the transmission component 120 respectively. Thus, the operator can remotely control the rock drill 110 and the transmission component 120 respectively. On the one hand, it can ensure that the rock drill 110 has a large driving force to ensure the stable opening of the residual iron discharge channel. On the other hand, it can help the operator stay away from the blast furnace 200 and avoid being burned by splashing molten iron.

[0062] It is understandable that some blast furnaces 200 that need to discharge residual iron have been corroded due to long-term use. After being repaired by using the technology of reusing old carbon bricks for casting, the strength of the cast layer inside the blast furnace 200 is relatively large. The pneumatic rock drill 110 and transmission component 120 can provide sufficient drilling force, which is more conducive to opening up the residual iron discharge channel.

[0063] It is understandable that since the molten iron discharged from the residual iron discharge channel has a high temperature and may even be accompanied by flames, using inert gases such as nitrogen and argon can suppress the flames and play a role in extinguishing the fire.

[0064] In some examples, the second pneumatic unit includes: a percussion air supply line connected to the rock drill 110 for providing power for the percussion of the rock drill 110; a rotation air supply line connected to the rock drill 110 for providing power for the rotation of the drill rod; and a purging air supply line connected to the purging pipe of the rock drill 110 for providing purging air to the rock drill 110.

[0065] In the above technical solution, the second pneumatic unit includes a percussion air supply line, a rotation air supply line, and a purging air supply line. The percussion air supply line, the rotation air supply line, and the purging air supply line are all connected to the rock drill 110. The percussion air supply line provides power for the percussion of the rock drill 110 to drive the drill rod of the rock drill 110 to perform the percussion action. The rotation air supply line provides power for the rotation of the drill rod to drive the drill rod of the rock drill 110 to rotate, which is beneficial to improving the opening speed of the residual iron discharge channel. The purging air supply line is connected to the purging pipe of the rock drill 110 and provides purging air to the rock drill 110. The purging air blows away the debris in the residual iron discharge channel on the one hand, and on the other hand, the purging air can also be used to reduce the temperature of the drill rod, which is beneficial to the continuous operation of the residual iron discharge channel.

[0066] In some examples, the control component 140 includes: a movement control unit, disposed in the first pneumatic unit, for controlling the transmission component 120 to drive the rock drill 110 to move forward or backward; a striking control unit, disposed in the striking air supply line, for controlling the start or stop of the striking function of the rock drill 110; a rotation control unit, disposed in the rotation air supply line, for controlling the forward, reverse, or stop rotation of the drill rod; and a purging control unit, disposed in the upper purging air supply line, for controlling the opening or closing of the purging air supply line.

[0067] In the above technical solution, the control component 140 includes a movement control unit, a drilling control unit, a rotation control unit, and a purging control unit. The rotation control unit is located on the first pneumatic unit and can control the magnitude and direction of the driving force provided by the first pneumatic unit to the transmission component 120, thereby enabling the transmission component 120 to perform bidirectional transmission in the first direction. That is, the movement control unit can control the transmission component 120 to drive the rock drill 110 to move forward or backward. The drilling control unit is located on the drilling air supply pipeline and can control the air supply status of the drilling air supply pipeline, thereby controlling the start or stop of the drilling function of the rock drill 110. The rotation control unit is located on the rotation air supply pipeline and can control the forward, reverse, or stop rotation of the drill rod of the rock drill 110 by controlling the air supply status of the rotation air supply pipeline. In practical applications, through the mutual cooperation of the movement control unit, the drilling control unit, the rotation control unit, and the purging control unit, a series of operations of the rock drill 110 during the rock drilling process can be realized.

[0068] Understandably, when residual iron needs to be discharged, the movement control unit controls the transmission assembly 120 to move the rock drill 110 closer to the blast furnace 200. At the same time, the striking control unit activates the striking function of the rock drill 110, and the rotation control unit controls the drill rod to rotate, so that the rock drill 110 can rotate and strike. Then, the purging control unit controls the purging air to be turned on, thereby performing the striking operation on the blast furnace 200 and opening a residual iron discharge channel. After the residual iron discharge channel is opened, the movement control unit controls the transmission assembly 120 to move the rock drill 110 away from the blast furnace 200, so that the rock drill 110 returns to its initial position. At the same time, the striking control unit deactivates the striking function of the rock drill 110, the rotation control unit stops the drill rod from rotating, and the purging control unit shuts off the purging air.

[0069] For example, a ventilation duct is provided on the drill pipe, and the purging air can be directly connected to the ventilation duct.

[0070] For example, the first pneumatic unit may employ two air ducts to control the movement of the transmission assembly 120 in two directions respectively.

[0071] In some examples, such as Figure 1 As shown, the transmission assembly 120 includes: a support member 121, on which the rock drill 110 is disposed; a transmission member 122 having a transmission rail extending along a first direction, on which the support member 121 is disposed; and a drive member 123, on which a pneumatic assembly 130 is connected, and the drive member 123 is used to drive the transmission member 122 to move the support member 121 along the first direction; wherein, the position height of the support member 121 is lower than the position height of the transmission member 122.

[0072] In the above technical solution, the transmission assembly 120 includes a support member 121, a transmission member 122, and a drive member 123. The support member 121 is used to hold the rock drill 110. The transmission member 122 has a transmission track extending along a first direction, and the support member 121 can move along the transmission track. The drive member 123 is connected to the pneumatic assembly 130 and is used to drive the transmission member 122, so that the transmission member 122 can drive the support member 121 to move along the first direction. Furthermore, the position height of the support member 121 is lower than that of the first transmission member 122. In practical applications, the rock drill 110 is mounted on the support 121, meaning the rock drill 110 is located below the transmission assembly 120. The height of the drill bit of the rock drill 110 when it contacts the blast furnace 200 determines the height of the tap hole in the residual iron discharge channel. When molten iron is discharged from the residual iron discharge channel, it flows downwards under gravity. The height of the transmission assembly 120 is higher than that of the rock drill 110, which helps to prevent the transmission assembly 120 from being corroded by molten iron and improves the service life of the device.

[0073] For example, the transmission component 122 may adopt a chain drive transmission method, the drive component 123 may adopt a pneumatic walking motor, and the pneumatic component 130 is connected to the pneumatic walking motor.

[0074] For example, the transmission component 122 may be provided to be longer so that the rock drill 110 can be located away from the blast furnace 200 to facilitate maintenance or replacement of the drill rod of the rock drill 110.

[0075] According to a second aspect of the present disclosure, a residual iron tapping system for a blast furnace 200 is provided, comprising: a residual iron tapping device 100 as described in any of the first aspects above; a furnace, wherein the blast furnace 200 has an iron tapping port on its peripheral wall, the iron tapping port being open along a second direction; a support assembly 300 connected to the blast furnace 200, wherein the residual iron tapping device 100 is disposed on the support assembly 300; wherein a drill rod is oriented toward the iron tapping port, there is an inclination angle of 7° between the first direction and the second direction, and the position height of the drill bit of the drill rod is higher than the position height of the tail of the drill rod.

[0076] Since the residual iron tapping system of the blast furnace 200 provided in this embodiment includes the residual iron tapping device 100 as proposed in any of the first aspects above, it has all the beneficial effects of the residual iron tapping device 100, which will not be elaborated here.

[0077] In addition, the blast furnace 200 residual iron tapping system according to the second aspect of the present disclosure also includes a blast furnace 200 and a support assembly 300. The residual iron tapping device 100 is mounted on the support assembly 300, which is connected to the blast furnace 200. This improves the system's integration and allows for a relatively fixed positional relationship between the residual iron tapping device 100 and the blast furnace 200. The blast furnace 200 has a tapping port on its peripheral wall that extends along a second direction. In practical applications, the second direction is usually horizontal. Since gas is often used to open the residual iron discharge channel in the blast furnace 200, this is because... The blast furnace 200 is cut by cutting to form a tapping hole that is open in a horizontal direction. In addition, there is a 7° angle between the first direction and the second direction, that is, there is a 7° angle between the forward direction of the rock drill 110 and the second direction. This is more conducive to the rock drill 110 opening up the residual iron discharge channel in the furnace wall of the blast furnace 200. Since the height of the drill bit of the drill rod is higher than the height of the tail of the drill rod, it can be ensured that the residual iron discharge channel is inclined downward from the inside of the blast furnace 200 to the perimeter wall of the blast furnace 200, so that the molten iron can flow out smoothly from the residual iron discharge channel under the action of gravity.

[0078] Understandably, using a 7° tilt angle ensures that the molten iron has a certain flow speed to prevent it from solidifying, and also prevents the molten iron from splashing due to excessive flow.

[0079] In some examples, such as Figure 1 As shown, the support assembly 300 includes: a frame 310 connected to the blast furnace 200, the frame 310 extending along a second direction; a connector 320, one end of the connector 320 connected to the frame 310, the other end of the connector 320 connected to the transmission assembly 120, the number of connectors 320 is multiple, and the multiple connectors 320 are arranged at intervals along the second direction; and a hoisting component 330 disposed on the frame 310, the drill rod passing through the hoisting component 330 so that the drill rod extends along a first direction.

[0080] In the above technical solution, the support assembly 300 includes a frame 310, connectors 320, and a hoisting component 330. The frame 310 is connected to the blast furnace 200 and extends along a second direction. The transmission assembly 120 is connected to the frame 310 via connectors 320. There are multiple connectors 320, and these multiple connectors 320 are spaced apart from each other along the second direction. In practical applications, the length of the connectors 320 gradually increases along the second direction, thereby enabling the transmission assembly 120 to extend along the first direction. Using multiple connectors 320 can ensure the connection strength between the transmission assembly 120 and the frame 310. On the other hand, the transmission direction of the transmission assembly 120 can be determined by the multiple connectors 320 to ensure the travel direction of the rock drill 110. The hoisting component 330 is set on the frame 310, and the drill rod passes through the hoisting component 330. Thus, the hoisting component 330 further restricts the movement direction of the drill rod to ensure that the drill rod can extend and move along the first direction.

[0081] Understandably, since the furnace wall of blast furnace 200 is relatively thick, the drill rod needs to be relatively long. During rock drilling operations, the drill rod is prone to deformation. The hoisting component 330 and the rock drill 110 body can restrict the drill rod from two points, which helps to avoid drill rod deformation.

[0082] It is understandable that the hoisting component 330 can be directly installed on the side of the frame 310 close to the blast furnace 200, or indirectly installed on the frame 310 and connected to the transmission component 120. Under the drive of the transmission component 120, it can move along the first direction together with the rock drill 110.

[0083] In some examples, such as Figure 1 As shown, it also includes: a feeding trough 400, which is welded to the blast furnace 200. The feeding trough 400 forms a channel, one end of which is connected to the tapping port. The channel is used to recover the molten iron discharged from the blast furnace 200; wherein, the channel extends along a first direction.

[0084] In the above technical solution, the residual iron tapping system of blast furnace 200 also includes a guide trough 400. The guide trough is welded to the peripheral wall of blast furnace 200. A channel is formed inside the guide trough 400. One end of the channel is connected to the tapping hole so that the molten iron discharged from the tapping hole can be discharged through the guide trough 400. The channel extends along the first direction, that is, there is a 7° angle between the channel and the horizontal direction. This can ensure that the molten iron has a certain flow speed, avoid the solidification of the molten iron, and also avoid splashing caused by the molten iron flowing too fast.

[0085] In one feasible embodiment, the other end of the channel of the feed trough 400 is connected to a steel trough. The interior of the steel trough is divided into multiple recycling tanks by multiple partitions. After the molten iron flows into the recycling tank, it solidifies into solid iron in the recycling tank. By using multiple partitions, the molten iron can be divided into multiple small volumes of iron before solidification, so that the solidified solid iron can be handled more easily.

[0086] In some examples, the interior of the feed chute 400 is constructed of refractory bricks.

[0087] In the above technical solution, the inside of the feed trough 400 is constructed with refractory bricks, which can reduce the corrosion of the feed trough 400 by molten iron and improve the service life of the feed trough 400.

[0088] In some examples, a cover plate is also included, disposed at the opening of the feed chute 400, located between the feed chute 400 and the rock drill 110.

[0089] In the above technical solution, a cover plate is also provided on the opening of the guide trough 400 located between the guide trough 400 and the rock drill 110. The cover plate can prevent molten iron from splashing from the opening of the guide trough 400 onto the rock drill 110, thus protecting the rock drill 110.
