Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery technology, and in particular to a hole-closing machine for a common base of a reduction furnace. Background Technology

[0002] In the field of metal smelting, horizontal metal reduction furnaces are widely used due to their advantages such as uniform heat distribution and convenient material conveying. However, during the operation of metal reduction furnaces, blockage at the discharge port often occurs. In such cases, a plugging machine is needed to unblock the metal reduction furnace. The plugging operation for horizontal metal reduction furnaces mainly relies on two types of equipment: a fixed plugging machine, which is fixedly connected to a single furnace body via a rigid support; and a mobile machine, which needs to be switched between different furnace bodies via tracks or sliding tables.

[0003] However, existing technologies have significant drawbacks in practical applications. Fixed equipment requires a separate opening and plugging mechanism for each reduction furnace, resulting in redundant production line equipment and a large amount of space occupied by the machine body and pipelines, leading to insufficient operating space on the production line. Although existing mobile equipment has a certain degree of flexibility, the positioning process relies on manual repeated adjustments of the longitudinal track and the lateral fine-tuning mechanism, which takes a long time to align and is easily affected by the thermal deformation of the furnace body, resulting in cumulative errors and making it difficult to ensure the continuity of operation.

[0004] Therefore, there is a need for a common base hole-closing machine for reduction furnaces that does not occupy operating space and has good operational continuity. Summary of the Invention

[0005] The main purpose of this utility model is to provide a hole-opening machine for a common base of a reduction furnace, which aims to solve the problems of existing hole-opening machines occupying too much operating space and having poor continuous operation efficiency.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Existing eye-opening and eye-blocking machines suffer from high levels of human intervention, insufficient mechanical reliability, difficulty in adapting to continuous production operations, long maintenance times, resulting in high production costs, large space requirements, and low operational efficiency.

[0029] Based on this, such as Figures 1-3As shown, this utility model proposes a common base plugging machine 1000 for a horizontal metal reduction furnace with multiple furnace openings, comprising: a slide rail assembly 100, which includes a first slide rail 110 and a second slide rail 120, the first slide rail 110 and the second slide rail 120 being arranged parallel to each other, the first slide rail 110 being located outside the second slide rail 120 and the extension directions of both the first slide rail 110 and the second slide rail 120 being perpendicular to the axial direction of the horizontal metal reduction furnace; and a plugging assembly 250200, which includes a first slide block 210, a support base 220, a drilling mechanism 230, a drill rod 240, and a plugging assembly 250, the first slide block 210 being slidably connected to the first slide rail 110, the support base 220 being located on top of the first slide block 210, and the drilling mechanism... Drilling mechanism 230 is located on top of support base 220 and is sleeved on drill rod 240. Drilling mechanism 230 and drill rod 240 are coaxially connected. Drill rod 240 is located on the side of drilling mechanism 230 near horizontal metal reduction furnace. Plugging assembly 250 includes barrel 251 and hydraulic drive device 252. Barrel 251 is located on top of support base 220 and spaced apart from drilling mechanism 230. Hydraulic drive device 252 is located at the top of barrel 251. Slag discharge assembly 300 includes collection cart 310, cleaning mechanism 320 and second slide block 330. Collection cart 310 is located on top of second slide block 330. Second slide block 330 is slidably connected to second slide rail 120. Cleaning mechanism 320 is located on top of collection cart 310 and abuts against drill rod 240.

[0030] In this embodiment, the first slide rail 110 and the second slide rail 120 are arranged in parallel, with the first slide rail 110 located on the side of the second slide rail 120 away from the metal reduction furnace. The first slide block 210 is slidably connected to the first slide rail 110, and the second slide block 330 is slidably connected to the second slide rail 120. When it is necessary to open and plug the metal reduction furnace, the first slide block 210 is operated by the operator to ensure that it slides to the corresponding furnace opening working position. Then, the opening and plugging assembly 250200 provided on the first slide block 210 is used to open and plug the furnace opening. The drilling mechanism 230 in the opening and plugging assembly 250200 drives the drill rod 240 to rotate and extend into the metal reduction furnace to complete the opening and plugging operation. The drilling mechanism 230 is connected to the first slide block 210 through a support frame. After the opening and plugging operation is completed, the drill rod 240... Driven by the drilling mechanism 230, the drill rod 240 detaches from the metal reduction furnace in a direction away from the furnace opening. The second slide 330 moves along the slide rail to the line connecting the first slide 210 and the furnace opening, allowing the cleaning mechanism 320 on the second slide 330 to contact the drill rod 240 and scrape off any remaining metal residue. The metal residue is then collected by the collection cart 310 and transferred, ensuring the hygiene of the production equipment and space, and enabling the recycling of the metal residue, thus reducing material loss. It is understood that the second slide 330 can also move in coordination with the first slide 210, and the second slide 330 remains relatively stationary with respect to the first slide 210.

[0031] In detail, the slide rail assembly 100 disclosed in this utility model also has a slide rail base 130 at its bottom. The slide rail base 130 is fixedly connected to the ground by bolts, and the base of the slide rail assembly 100 serves as a common base. More specifically, the number of the first slide block 210 and the second slide block 330 can be adjusted according to actual needs. Multiple first slide blocks 210 and second slide blocks 330 are used together for the first slide rail 110 or the second slide rail 120, enabling this utility model to perform hole-closing operations on multiple furnace openings of metal reduction furnaces at the same time, providing excellent continuous operation capability. The hole-closing assembly 250 is connected to an external mud source, and the external mud source is pumped to the barrel 251 by a hydraulic drive device 252. The barrel 251 then fills the metal reduction furnace with hole-closing mud. The first slide block 210 allows the barrel 251 to be kept away from the metal reduction furnace during non-hole-closing operations, extending its service life.

[0032] It is understandable that the interval between the first slide rail 110 and the second slide rail 120, as well as the interval between the second slide rail 120 and the metal reduction furnace, can be adjusted according to the actual working space.

[0033] In one embodiment, the first slide block 210 is provided with a first drive motor 211, which is disposed at one end of the first slide block 210. The bottom end of the first slide block 210 is also provided with a first pulley 212, and the first drive motor 211 is rotatably connected to the first pulley 212. The second slide block 330 is provided with a second drive motor 331, which is disposed at one end of the second slide block 330. The bottom end of the second slide block 330 is also provided with a second pulley 332, and the second drive motor 331 is rotatably connected to the second pulley 332.

[0034] In this embodiment, the first slide rail 110 and the second slide rail 120 are I-beams, and the first pulley 212 and the second pulley 332 are track pulleys. The first slide block 210 drives the first pulley 212 through the first drive motor 211, thereby moving the first slide block 210 along the extension direction of the first slide rail 110. The second slide block 330 drives the second pulley 332 through the second drive motor 331, thereby moving the second slide block 330 along the extension direction of the second slide rail 120.

[0035] Understandably, the output power of the first drive motor 211 and the second drive motor 331 can be adjusted by the operator according to actual needs.

[0036] In one embodiment, the first slide block 210 is provided with a first limiting clamp 213, and the second clamp is provided with a second limiting clamp 333. The first limiting clamp 213 is disposed at the bottom of the first slide block 210 and abuts against both sides of the first pulley 212; the second limiting clamp 333 is disposed at the bottom of the second slide block 330 and abuts against both sides of the second pulley 332.

[0037] In this embodiment, the first limiting clamp 213 is disposed at the bottom of the first slide block 210. The first limiting clamp 213 is provided with an elastic element and brake pads connected to both sides of the elastic element. The ends of the two brake pads are respectively disposed on both sides of the first pulley 212. The two brake pads are braked or unlocked relative to the first pulley 212 by the compression or extension of the elastic element. When the first slide block 210 moves to the working position, the operator performs the braking operation, and the first limiting clamp 213 brakes the first pulley 212 to ensure that the first slide block 210 can be located at the working position. The second limiting clamp 333 is disposed at the bottom of the second slide block 330. The second limiting clamp 333 is provided with two brake pads corresponding to the second pulley 332. The second limiting clamp 333 can drive the two brake pads to brake the second pulley 332.

[0038] In one embodiment, the first slide 210 is provided with a first laser sensor 214, and the second slide 330 is provided with a second laser sensor 334. The first laser sensor 214 is disposed on both sides of the first slide 210 and faces the second slide 330. The second laser sensor 334 is disposed on both sides of the second slide 330 and faces the horizontal metal reduction furnace.

[0039] It is understood that the laser sensor involved in this utility model includes a laser emitter and a laser receiver. In this embodiment, the first laser sensor 214 is disposed at both ends of the first slide block 210 along the extension direction of the first slide rail 110, and the laser emitter in the first laser sensor 214 emits laser light from the first slide block 210 toward the metal reduction furnace. The metal reduction furnace and the second slide block 330 are provided with reflection marks corresponding to the first laser sensor 214. When the laser emitted by the first laser sensor 214 shines on the reflection mark, it reflects the laser back to the laser receiver on the first laser sensor 214, ensuring that the first slide block 210 can move to the correct working position. Similarly, the second slide block 330 is also provided with a second laser sensor 334, which is used to emit and receive laser light to ensure that the second slide block 330 moves to the position required in the production process.

[0040] In another embodiment, the first slide 210 and the second slide 330 are further provided with a linkage controller. The linkage controller can receive the alignment signals emitted by the first laser sensor 214 and the second laser sensor 334, and after completing the alignment, send start and stop signals to the first drive motor 211, the second drive motor 331, the first limit clamp 213, and the second limit clamp 333 to realize the coordinated operation of the first slide 210 and the second slide 330.

[0041] In one embodiment, the drilling mechanism 230 includes a housing 231 and a rotary motor. The top end of the housing 231 is connected to the support base 220. The rotary motor is disposed inside the housing 231 and the axis of the rotary motor is coaxial with the axis of the drill rod 240. The rotary motor is connected to the drill rod 240 and drives the drill rod 240 to rotate.

[0042] In this embodiment, the drilling mechanism 230 further includes a hydraulic thruster 232, which is disposed inside the housing 231 and coaxially connected to the drill rod 240. The hydraulic thruster 232 drives the drill rod 240 to extend and retract along the axial direction of the metal reduction furnace, allowing the drill rod 240 to enter the furnace opening of the metal reduction furnace to complete the hole-opening and plugging operation. A rotary motor is disposed inside the housing 231 and connected to the drill rod 240. The rotary motor drives the drill rod 240 to rotate around its axis, increasing the efficiency of the hole-opening and plugging operation. After the hole-opening and plugging operation is completed, the drill rod 240 is rotated in the opposite direction to remove it from the metal reduction furnace, and the cleaning mechanism 320 scrapes off any remaining metal residue on the drill rod 240.

[0043] In one embodiment, the first slide 210 is further provided with a lifting column 215 and a lifting motor 216. The bottom end of the lifting column 215 is located at the top of the support base 220, and the top end of the lifting column 215 is bolted to the outer shell 231. The lifting motor 216 is located at one end of the support base 220 and connected to the lifting column 215. The lifting motor 216 drives the top end of the lifting column 215 to move up and down relative to the support base 220.

[0044] In this embodiment, there are eight lifting columns 215. Four lifting columns 215 are evenly spaced around the middle section of the outer casing 231 on the support base 220, and the other four are evenly spaced around the ends of the outer casing 231 on the support base 220. A lifting motor 216 is located at the top of the support base 220 and is connected to the lifting columns 215 via a gear set. The lifting motor 216 drives the top of the lifting columns 215 to rise or fall relative to the support base 220. The outer casing 231 has a bottom fixing plate corresponding to the lifting columns 215, and the top of the lifting columns 215 is bolted to the bottom surface of the bottom fixing plate.

[0045] In one embodiment, the top of the collection vehicle 310 is provided with a guide channel 311, and the opening direction of the inlet end of the guide channel 311 is parallel to the axial direction of the horizontal metal reduction furnace.

[0046] In this embodiment, the guide channel 311 extends along the axial direction of the metal reduction furnace, and the inlet end is located on the side close to the metal reduction furnace and vertically below the space of the cleaning mechanism 320, so as to receive the metal residue generated by the cleaning mechanism 320 after cleaning the drill rod 240.

[0047] In another embodiment, the bottom of the collection vehicle 310 may also be equipped with a material conveyor belt to collect and reuse metal residues.

[0048] In one embodiment, the cleaning mechanism 320 includes a frame 321 and a scraper 322. The frame 321 is disposed on the top of the second slide 330 and extends upward along the axis of the second slide 330. The scraper 322 is detachably connected to the top of the frame 321 and abuts against the drill rod 240.

[0049] In this embodiment, the frame 321 is provided with a lifting component, which is located at the top of the frame 321 and connected to the scraper 322. The lifting component can drive the scraper 322 to extend upward along the normal direction of the top surface of the second slide block 330 until it is parallel to the drill rod 240. During the process of retracting the drill rod 240, the drill rod 240 can be cleaned to ensure the feasibility of continuous operation of the drill rod 240.

[0050] This utility model discloses a common base hole-opening machine for a reduction furnace. A first slide rail and a second slide rail are vertically arranged along the axis of a multi-furnace metal reduction furnace. The slide rail base serves as a common base, and multiple first sliding seats and multiple second sliding seats are correspondingly provided on the first and second slide rails, respectively. These multiple first and second sliding seats share the same first or second slide rail, allowing simultaneous operation on the multi-furnace metal reduction furnace. The drill rod in the hole-opening assembly on the first sliding seat can reciprocate and rotate along the axis of the metal reduction furnace, improving the efficiency of hole-opening operations. The slag removal assembly on the second sliding seat has a scraper corresponding to the drill rod for cleaning.
