Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for metallurgical smelting, and more specifically to a slag flushing water pipe crystallization cleaning device. Background Technology

[0002] In the water quenching process of non-ferrous metallurgy, the slag flushing water pipe is a core supporting equipment for the water quenching and cooling of smelting slag and matte. During actual production, the hard gangue components such as quartz and limestone contained within the smelting slag and matte continuously erode the inner wall of the flushing water pipe along with the high-temperature slag-water mixture, constantly precipitating, adhering, and accumulating, eventually forming a dense, extremely hard composite crystalline scale layer. This type of crystal has strong adhesion and high consolidation strength, making it difficult to remove using conventional cleaning methods. The continuous thickening of the crystals significantly reduces the effective diameter of the flushing water pipe, lowering the efficiency of water quenching and slag conveying. In severe cases, it can cause blockages in the flushing water pipe and system pressure buildup, directly affecting the continuous and stable operation of the non-ferrous metallurgical water quenching production line.

[0003] Currently, the non-ferrous metallurgical industry lacks dedicated automated equipment for the crystallization cleaning of water-quenched slag flushing pipes, relying heavily on manual methods of chiseling and breaking them with pneumatic picks. Due to production constraints, heavily scaled slag flushing pipes cannot be cleaned online and must be cut and disassembled on-site, then transported by forklift or crane to a dedicated operating platform for offline centralized cleaning. This traditional manual cleaning method has several drawbacks: First, the crystals in the slag flushing pipes contain hard gangue, making them difficult to break and requiring extensive manual chiseling, resulting in extremely low efficiency and failing to meet the periodic maintenance needs of the production line. Second, uneven force during manual hammering easily damages the inner wall of the slag flushing pipe, causing thinning and deformation, significantly shortening its lifespan. Third, the stability of manually positioning and fixing the pipes after hoisting is poor, leading to swaying and displacement during operation, resulting in numerous blind spots and incomplete cleaning. Fourth, manual open-air chiseling creates dust and scattered waste, resulting in a harsh working environment and significant safety hazards.

[0004] Existing conventional slag flushing pipe cleaning equipment has a simple structure and cannot adapt to the hard gangue crystallization conditions of ferrous metallurgical water-quenched slag flushing pipes. It is also not suitable for the operation mode of offline centralized cleaning of slag flushing pipes after cutting and hoisting. It lacks a dedicated structure for precise positioning, indexing and grooving, and stable material pushing and protection of slag flushing pipes, making it difficult to achieve efficient and thorough cleaning of high-hardness crystals.

[0005] Therefore, there is an urgent need to develop a dedicated automated crystallization cleaning device that is compatible with non-ferrous metallurgical water quenching processes, targets hard gangue crystallization, and is suitable for offline centralized cleaning of slag flushing water pipes. Summary of the Invention

[0006] In view of this, the present invention provides a crystallization cleaning device for slag flushing water pipes, which aims to solve the technical problems of high cleaning difficulty, low manual cleaning efficiency, easy damage to slag flushing water pipes, and poor equipment adaptability caused by the crystallization of hard gangue such as quartz and limestone in existing non-ferrous metallurgical water quenching slag flushing water pipes. It is adapted to the working conditions of cutting and hoisting slag flushing water pipes to the platform for centralized offline cleaning, and realizes the integrated automated operation of hard crystal grooving, crushing and slag discharge.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A fixing frame, which is fixed to one end of the placement platform; A lifting mechanism is installed inside the frame of the fixed frame, and a mounting plate is fixed to its lifting end; The cleaning mechanism includes a hydraulic cylinder, a grooving tool, and a pusher tool. The hydraulic cylinder is fixed to the top surface of the mounting plate, and its hydraulic rod can pass through the fixed frame and extend into the inner cavity of the flushing water pipe as the lifting mechanism moves up and down. Both the grooving tool and the pusher tool can be engaged with the hydraulic rod. The grooving tool is used to cut the hard crystalline layer on the inner wall of the flushing water pipe and open a crushing groove. The pusher tool is used to push the loosened crystalline waste slag outward along the inner cavity of the flushing water pipe after grooving.

[0009] The beneficial effects of this invention are as follows: the flushing pipe to be cleaned is placed on a support, and the rotation of the flushing pipe can be achieved through a drive wheel and a rotary bearing; the cleaning mechanism uses the lifting mechanism to adapt to the cleaning requirements of flushing pipes with different diameters, wall thicknesses, and crystal thicknesses; the grooving tool first cuts and breaks the crystals inside the flushing pipe, and then the pusher tool pushes the crystal waste outward; this invention enables real-time automated cleaning of flushing pipes without the need for manual knocking or chiseling, greatly improving cleaning efficiency.

[0010] Preferably, the grooving tool includes a grooving connecting cylinder, a base, and a cutting blade body that are sequentially and securely connected; the grooving connecting cylinder can be sleeved on the hydraulic rod and secured by a first locking pin; the cutting blade body is conical, with the end furthest from the base being the cutting end.

[0011] Preferably, the pusher blade comprises a pusher connecting cylinder, a vertical plate, and a pusher blade body that are sequentially and fastened together; the pusher connecting cylinder can be sleeved on the hydraulic rod and fastened by a second locking pin; the pusher blade body is arc-shaped, and its arc-shaped concave surface forms a pusher cavity with the surface of the vertical plate. The pusher cavity of the pusher blade body can push the broken crystals out of the flushing water pipe.

[0012] Preferably, the lifting mechanism includes a fixed plate and a pair of scissor arms; the fixed frame is a quadrangular prism frame welded from multiple columns and multiple crossbeams; the periphery of the fixed plate is welded to the lower ends of the multiple columns; the scissor arms include a first support arm and a second support arm hinged to each other; the lower end of the first support arm is hinged to the top surface of the fixed plate, and the lower end of the second support arm is slidably connected to the fixed plate; the upper ends of both the first and second support arms are hinged to the bottom surface of the mounting plate. The scissor lift allows adjustment of the hydraulic rod's working height to adapt to the crystallization cleaning needs of slag flushing water pipes with different wall thicknesses, pipe diameters, and crystallization thicknesses.

[0013] Preferably, the device further includes a lifting drive unit, which comprises a guide rail, a slider, a lifting motor, and a screw. The guide rail is fixed to the top surface of the fixed plate. The slider is slidably connected to the guide rail. The lower end of the second support arm is hinged to the top surface of the slider. The lifting motor is located at the end of the fixed plate away from the first support arm. The screw is threadedly connected to the slider, and one end of the screw is connected to the output shaft of the lifting motor via a key. The lifting motor uses the screw to realize the sliding of the slider along the guide rail, thereby realizing the lifting of the mounting plate, resulting in high control precision and a more stable lifting process.

[0014] Preferably, the mounting plate also includes a locking plate; each of the four corners of the mounting plate has a clearance groove; the inner wall of the clearance groove has an assembly gap with the circumferential surface of the column; the locking plate can be engaged within the assembly gap to lock the horizontal freedom of the mounting plate. During the lifting process, the mounting plate does not directly contact the column, effectively avoiding friction and wear during height adjustment and operation; after height adjustment, the locking plate fills the assembly gap for limiting and locking, preventing horizontal displacement of the mounting plate during hydraulic rod operation, and effectively protecting the scissor arm from damage by lateral tension and shearing forces.

[0015] Preferably, it also includes a slag receiving trough; the top surface of the placement platform has a discharge port; the slag receiving trough is located at the end of the placement platform away from the fixed frame and is connected to the discharge port to receive waste slag. The slag receiving trough is used to achieve waste slag collection and unified treatment.

[0016] Preferably, the support and restraint member further includes a first arc-shaped plate, which is fixed to the top surface of the placement platform, and the slewing bearing is rotatably connected to the arc-shaped concave surface of the first arc-shaped plate.

[0017] Preferably, the indexing adjustment component includes a second arc-shaped plate, a rotating shaft, a rotating motor, a transmission gear, and a driven gear. Two second arc-shaped plates are arranged opposite each other, and both plates are fixed to the top surface of the placement platform. The rotating shaft is rotatably connected to the concave arc surfaces of the two second arc-shaped plates. The drive wheel is fixed to the rotating shaft and positioned between the two arc-shaped plates. The rotating motor is fixed to the placement platform. The transmission gear is fixed to the output shaft of the rotating motor. The driven gear is fixed to one end of the rotating shaft and meshes with the transmission gear. The rotating motor drives the drive wheel to rotate actively, and in conjunction with the passive rotation of the slewing bearing, achieves indexing adjustment of the slag flushing water pipe, ensuring comprehensive crystallization cleaning of the inner wall of the slag flushing water pipe.

[0018] Preferably, the top surface of the placement platform away from the fixing frame is detachably connected to an anti-slip hook; the anti-slip hook can engage with the flushing water pipe to limit the axial displacement of the flushing water pipe. The anti-slip hook prevents the flushing water pipe from breaking or the device from being damaged due to axial displacement during the cleaning operation.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a slag flushing water pipe crystallization cleaning device, which has the following beneficial effects: 1. This invention replaces traditional manual chiseling with mechanical automation. Through precise lifting and positioning, stable hydraulic feeding, intermittent indexing rotation of the slag flushing water pipe, and special tools for step-by-step operation, it achieves integrated automated cleaning of hard crystallization in the slag flushing water pipe, including grooving, crushing, and slag discharge. This significantly reduces the intensity of manual labor and greatly improves the efficiency of crystallization cleaning of the slag flushing water pipe.

[0020] 2. Through multiple mechanical protection structures, the clamping plate can prevent the scissor mechanism from being strained, the drive wheel can prevent the flushing water pipe from spinning idly, and the limiting plate can prevent the flushing water pipe from slipping axially, thus comprehensively improving the stability and safety of the device operation and reducing the failure rate.

[0021] 3. This invention is equipped with a special combination of grooving and pushing tools, which specifically solves the industry problems of high hardness, difficulty in crushing, and incomplete slag removal of hard gangue crystals in non-ferrous metallurgical slag flushing water pipes. The grooving and crushing is thorough and the material is pushed and slag is removed cleanly, which effectively improves the quality of crystallization cleaning and ensures that the diameter of the slag flushing water pipe meets the standards.

[0022] 4. This invention is precisely adapted to the maintenance conditions of slag flushing water pipes in the non-ferrous metallurgical water quenching industry. It is specifically designed for offline centralized cleaning of slag flushing water pipes that have been cut, disassembled, or lifted to the operating platform by forklifts / cranes. It is adaptable to various pipe diameters and crystal thicknesses, and has strong versatility. At the same time, it adopts a closed centralized slag discharge structure, which effectively suppresses dust diffusion and greatly improves the harsh working environment of traditional manual cleaning.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the existing technology, the non-ferrous metallurgical industry lacks dedicated automated equipment for the crystallization cleaning of water-quenched slag flushing pipes. The industry has long relied on manual methods of chiseling and breaking the pipes with pneumatic picks, which is labor-intensive, inefficient, and prone to generating dust and causing environmental pollution. Furthermore, manual cleaning can result in incomplete cleaning and damage to the slag flushing pipes. Therefore, this invention discloses a crystallization cleaning device for slag flushing pipes, specifically designed for offline centralized cleaning of slag flushing pipes that have been cut and dismantled on the production line and transported to a dedicated operating platform by forklifts or cranes.

[0028] See appendix Figure 1 To be continued Figure 6 According to an embodiment of the present invention, a slag flushing water pipe crystallization cleaning device includes a placement platform 2, a support mechanism 6, a fixing frame 1, a lifting mechanism 3, and a cleaning mechanism 4. The support mechanism 6 includes an indexing adjustment component 62 fixed to the top surface of the placement platform 2 and multiple sets of support restraint components 61. A drive wheel 623 for driving the slag flushing water pipe to rotate is rotatably connected to the indexing adjustment component 62, and a rotary bearing 612 that can roll against the outer wall of the slag flushing water pipe is rotatably connected to the support restraint components 61. The fixing frame 1 is fixed to one end of the placement platform 2. The lifting mechanism 3 is mounted on the fixing frame 2. The frame 1 is housed within a frame, and its lifting end is fixed with an installation plate 33. The cleaning mechanism 4 includes a hydraulic cylinder 41, a grooving tool 42, and a pusher tool 43. The hydraulic cylinder 41 is fixed to the top surface of the installation plate 33, and its hydraulic rod can pass through the fixed frame 1 and extend into the inner cavity of the slag flushing water pipe as the lifting mechanism 3 moves up and down. Both the grooving tool 42 and the pusher tool 43 can be engaged with the hydraulic rod. The grooving tool 42 is used to cut the hard crystalline layer on the inner wall of the slag flushing water pipe and open a crushing groove. The pusher tool 43 is used to push the loosened crystalline waste slag outward along the inner cavity of the slag flushing water pipe after grooving.

[0029] like Figure 1 As shown, before the operation, based on the pipe diameter and the thickness of the crystallization on the inner wall of the slag flushing water pipe, the operating height of the mounting plate and hydraulic cylinder is precisely adjusted using the lifting mechanism, and the central axis of the hydraulic rod is aligned with the central axis of the slag flushing water pipe. During the cleaning process, a grooving tool is first installed on the hydraulic rod to perform a fixed-point grooving operation on the hard crystallized layer on the inner wall of the slag flushing water pipe. After a single grooving operation, the drive wheel is used to drive the slag flushing water pipe to rotate in increments until multiple evenly distributed broken grooves are formed on the crystallized layer on the inner wall of the slag flushing water pipe, completely cutting the dense crystallization structure, causing the overall crystallization to separate and loosen, and eliminating the high-strength adhesion between the crystallization and the inner wall of the slag flushing water pipe. Then, a pusher tool is installed to push the loose and broken crystallized waste residue inside the slag flushing water pipe outward as a whole.

[0030] To further optimize the above technical solution, the grooving tool 42 includes a grooving connecting cylinder 421, a base 422, and a cutting blade 423 that are sequentially and fastened together; the grooving connecting cylinder 421 can be sleeved on the hydraulic rod and fastened by a first locking pin 424; the cutting blade 423 is conical, with the end away from the base 422 being the cutting end; the pusher tool 43 includes a pusher connecting cylinder 431, a vertical plate 432, and a pusher blade 433 that are sequentially and fastened together; the pusher connecting cylinder 431 can be sleeved on the hydraulic rod and fastened by a second locking pin 434; the pusher blade 433 is arc-shaped, with its arc-shaped concave surface forming a pusher cavity with the plate surface of the vertical plate 432.

[0031] like Figure 5 and 6 As shown, both the slotted connecting cylinder and the pusher connecting cylinder have pin holes, and the end of the hydraulic rod away from the hydraulic cylinder has a through hole. During assembly, the slotted connecting cylinder or the pusher connecting cylinder is sleeved on the hydraulic rod and the through hole corresponds to the pin hole. Then, it is fastened by locking pin. The snap-fit ​​method facilitates the replacement of the tool.

[0032] The cutting blade gradually tapers from the root to the free end to form a tapered cutting tip, and the cutting blade has a bent cantilever structure. During operation, the flushing water pipe remains stationary and is grouted at a fixed point by axial feeding with a hydraulic rod. After each grooving, the flushing water pipe rotates at intervals and is locked in position again. Through multiple staggered grooving, a uniform crushing groove network is formed on the surface of the crystal layer, effectively cutting the dense crystal layer composed of quartz and limestone gangue, thus loosening the overall crystal layer. The pusher cavity on the pusher blade can hold the loosened and crushed crystal material after grooving, and the crystal waste is smoothly pushed outward and discharged from the flushing water pipe by the axial feeding action of the hydraulic rod.

[0033] To further optimize the above technical solution, the hydraulic cylinder adopts a double-chamber hydraulic cylinder with an effective working stroke of 3500mm. The hydraulic cylinder is connected to a hydraulic system, which is equipped with a three-phase drive motor, a gear pump, an oil tank with a volume of not less than 250L, a solenoid directional valve, and a hydraulically controlled check valve. The hydraulically controlled check valve is used to lock the feed position of the hydraulic rod to prevent retraction during operation. The hydraulic system also integrates an air-cooling heat dissipation mechanism to achieve constant temperature heat dissipation during continuous operation of the hydraulic system and avoid high temperature overload failure.

[0034] To further optimize the above technical solution, the lifting mechanism 3 includes a fixed plate 31 and paired scissor arms 32; the fixed frame 1 is a quadrangular prism frame welded from multiple columns 11 and multiple crossbeams 12; the periphery of the fixed plate 31 is welded to the lower ends of the multiple columns 11; the scissor arms 32 include a first support arm 321 and a second support arm 322 hinged to each other; the lower end of the first support arm 321 is hinged to the top surface of the fixed plate 31, and the lower end of the second support arm 322 is slidably connected to the fixed plate 31; the upper ends of both the first support arm 321 and the second support arm 322 are hinged to the bottom surface of the mounting plate 33; the mounting plate 33 and the fixed plate 31 are arranged opposite to each other. The lifting mechanism 3 adopts a scissor lift, which makes the lifting process more stable and the range controllable.

[0035] To further optimize the above technical solutions, such as Figure 3 As shown, it also includes a lifting drive unit, which includes a guide rail 34, a slider 35, a lifting motor 36, and a screw 37. The guide rail 34 is fixed to the top surface of the fixed plate 31. The slider 35 is slidably connected to the guide rail 34. The lower end of the second support arm 322 is hinged to the top surface of the slider 35. The lifting motor 36 is located at the end of the fixed plate 31 away from the first support arm 321. The screw 37 is threadedly connected to the slider 35, and one end of it is connected to the output shaft of the lifting motor 36 via a key. The horizontal displacement of the slider 35 drives the scissor arm 32 to expand or retract synchronously, thereby realizing the lifting and adjustment of the mounting plate 33.

[0036] In this embodiment, a locking plate 38 is also included; a clearance groove 331 is provided at each of the four corners of the mounting plate 33; there is an assembly gap between the inner wall of the clearance groove 331 and the circumferential surface of the column 11; the locking plate 38 can be locked in the assembly gap to lock the horizontal degree of freedom of the mounting plate 33.

[0037] like Figure 2 As shown, during the up-and-down movement of the mounting plate within the fixed frame, the presence of the clearance groove prevents the mounting plate from sliding against the column, completely avoiding friction, scratches, and wear between the mounting plate and the column during lifting, adjustment, and operation. Once the lifting position is stable, a locking plate is used to horizontally lock the mounting plate within the assembly gap, preventing the horizontal force generated by the extension and retraction of the hydraulic rod from causing the mounting plate to shift. This effectively prevents the scissor arm from continuously bearing alternating lateral tension, avoiding deviation, wear, strain, and deformation damage, and stabilizing the overall machine's operating posture and cutting accuracy.

[0038] To further optimize the above technical solution, limiters 7 are fixed on the outer wall of the column 11 at the highest lifting position and the lowest lowering position of the mounting plate 33. When the scissor lift rises or falls to the preset limit stroke, the limiter 7 triggers a power-off signal, immediately cutting off the power supply to the lifting motor 36, limiting the scissor lift from overtravel operation, effectively avoiding malfunctions such as scissor arm 32 being squeezed and deformed, and mechanism jamming, and comprehensively ensuring the safe operation of the equipment.

[0039] To further optimize the above technical solution and facilitate centralized collection and treatment of waste residue, a slag receiving trough 8 is also included; a discharge port 21 is provided on the top surface of the placement platform 2; the slag receiving trough 8 is located at the end of the placement platform 2 away from the fixed frame 1 and is connected to the discharge port 21 to receive waste residue. The discharge port 21 has a concave structure, running through both ends of the axial direction of the slag flushing water pipe corresponding to the entire anti-slag platform 2. The discharge port 21 is provided with a discharge trough at the position corresponding to the slag receiving trough 8. The concave discharge structure can prevent powder from splashing and causing environmental pollution during the pushing process.

[0040] To further optimize the above technical solution, the support restraint member 61 also includes a first arc-shaped plate 611, which is fixed to the top surface of the placement platform 2. The rotary bearing 612 is rotatably connected to the arc-shaped concave surface of the first arc-shaped plate 611. The indexing adjustment member 62 includes a second arc-shaped plate 621, a rotating shaft 622, a rotating motor 626, a transmission gear 625, and a driven gear 624. There are two second arc-shaped plates 621 arranged opposite to each other, and both second arc-shaped plates 621 are fixed to the top surface of the placement platform 2. The rotating shaft 622 is rotatably connected to the arc-shaped concave surface of the two second arc-shaped plates 621. The drive wheel 623 is fixed on the rotating shaft 622 and placed between the two second arc-shaped plates 621. The rotating motor 626 is fixed on the placement platform 2. The transmission gear 625 is fixed on the output shaft of the rotating motor 626. The driven gear 624 is fixed to one end of the rotating shaft 622 and meshes with the transmission gear 625.

[0041] like Figure 1 As shown, two support restraints are provided at the end of the flushing water pipe furthest from the fixed frame. These supports are used to support the flushing water pipe and ensure its effective indexing rotation. At the end of the flushing water pipe corresponding to the fixed frame, a support restraint and an indexing adjustment component are provided on the placement platform. Figure 4As shown, the outer surface of the drive wheel is textured with anti-slip patterns to increase the friction between the outer wall of the flushing pipe and the drive wheel. Static friction drives the flushing pipe to achieve precise indexing rotation, preventing the drive wheel from failing to synchronize with the flushing pipe's rotation. In this embodiment, the drive wheel's active rotation is achieved through the transmission of a rotating motor, transmission gears, and driven gears, thus realizing the indexing adjustment of the flushing pipe. The entire grooving operation of the flushing pipe adopts an intermittent operation mode of stopping the rotation and indexing the angle. During a single hydraulic grooving process, the flushing pipe remains completely stationary, ensuring grooving accuracy and cutting stability. After a single grooving is completed, the rotating motor drives the flushing pipe to rotate to a fixed angle and lock it in place. Then, in conjunction with the hydraulic rod, the next crystallization grooving is completed. Through multiple cycles of indexing grooving, the entire crystallization area of ​​the inner wall of the flushing pipe is cut and broken without any dead angles.

[0042] To further optimize the above technical solution, a controller 5 is also included. The controller 5 is used to control the axial extension and retraction of the hydraulic rod, and the start and stop of the lifting motor 36 and the rotating motor 626.

[0043] In this embodiment, an anti-slip hook 22 is detachably connected to the top surface of the placement platform 2 at the end away from the fixing frame 1; the anti-slip hook 22 can be engaged with the slag flushing water pipe to limit the axial displacement of the slag flushing water pipe. During operation, the anti-slip hook 22 can engage and limit the end face of the slag flushing water pipe, and can withstand the axial pushing load of the hydraulic rod throughout the entire process, limiting the axial slippage and detachment of the slag flushing water pipe, and ensuring the stability and safety of high-load pushing operation.

[0044] In this embodiment, the placement platform and the fixing frame are welded into an integral rigid support, which has high overall structural strength and small deformation. Through the coordinated operation of multiple mechanisms such as scissor lift height adjustment, hydraulic rod axial feeding, slag flushing water pipe rotation and functional tool switching, it can be adapted to the crystallization cleaning operation of slag flushing water pipes with different pipe diameters, and has strong versatility.

[0045] This invention is applicable to smelting enterprises in the non-ferrous metallurgical industry with water quenching processes. It is specifically designed for offline centralized cleaning of slag flushing water pipes that have been cut and dismantled from the production line and transported to a dedicated operating platform by forklifts or cranes. Before operation, based on the pipe diameter and the thickness of the crystallization on the inner wall of the slag flushing water pipe, the working height of the mounting plate and hydraulic cylinder is precisely adjusted using a scissor lift. The central axis of the hydraulic rod is calibrated to maintain coaxiality with the central axis of the slag flushing water pipe. During height adjustment, the reserved gap between the mounting plate and the column effectively prevents structural friction and scratches. After adjustment, a locking plate is installed within the gap to prevent the mounting plate from horizontally shifting during hydraulic rod extension and retraction. This fundamentally prevents the scissor arm from deforming or being damaged by lateral tension. At the same time, upper and lower limiters limit the lifting limit stroke to prevent damage to the lifting mechanism from overtravel.

[0046] In the actual cleaning process, the slag flushing water pipe to be cleaned is first hoisted into place and stably placed on the support mechanism to achieve radial flexible support and limitation of the slag flushing water pipe. The anti-slip hook at the tail end is then clamped onto the end face of the slag flushing water pipe to complete the axial locking and fixation of the slag flushing water pipe. This can effectively resist the reverse impact force during crystallization cutting and material pushing, and prevent the slag flushing water pipe from shifting or slipping. The rotating motor is started, and the rough drive wheel is driven through the gear pair to provide power for the indexing rotation of the slag flushing water pipe.

[0047] Assemble the grooving tool, start the hydraulic system, and initially keep the flushing water pipe stationary. The dual-chamber hydraulic rod is fed axially at a constant speed, and the bent conical cutting tool extends into the inside of the flushing water pipe to complete the fixed-point grooving operation on the hard crystalline layer on the inner wall of the flushing water pipe. After a single grooving is completed, retract the hydraulic rod, start the rotating motor to drive the flushing water pipe to rotate at a preset fixed angle, then stop and lock, and advance the hydraulic rod again to complete the grooving of the next area. Repeat the cycle of indexing angle and stationary grooving to form multiple evenly distributed breaking grooves on the crystalline layer on the inner wall of the flushing water pipe, completely cutting the dense crystalline structure, causing the overall crystal to stratify and loosen, and eliminating the high-strength adhesion between the crystal and the inner wall of the flushing water pipe.

[0048] After the grooving and crushing process is completed, the hydraulic rod is retracted, the grooving tool is disassembled, and the pusher tool is replaced and assembled. The hydraulic rod is started again to feed, and the arc-shaped pusher tool fits against the inner wall of the flushing water pipe, pushing the loose and broken crystallized waste slag in the flushing water pipe outward as a whole. The waste slag falls directly into the slag receiving trough through the discharge port, completing the closed automatic slag discharge and collection.

[0049] Throughout the operation, the hydraulic system continuously dissipates heat at a constant temperature through air-cooled components, and locks the hydraulic rod feed position with a hydraulically controlled check valve to ensure operational stability. Multiple protective structures provide full protection, effectively avoiding equipment failures and safety hazards. It can continuously complete multiple batches of crystallization cleaning operations for flushing slag and slag-flushing water pipes, with high operating efficiency and stable cleaning results.
