Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and in particular relates to a water curtain protective high-pressure water jet cleaning device for ingot bottom pads. Background Technology

[0002] In the alloy forging and metallurgical industry, smelting is a crucial preceding process. The ingot base pad of the crystallizer, as a refractory material component placed at the bottom of the crystallizer to support the high-temperature molten alloy, plays a key role in preventing the bottom of the crystallizer from being corroded or stuck by the high-temperature alloy liquid, thereby ensuring the safety and smooth progress of the smelting process.

[0003] However, under repeated high temperature and high pressure, the molten alloy will undergo a violent physicochemical reaction with the surface of the base pad, forming a layer of alloy residue with complex composition, dense structure and extremely strong adhesion. If this residue is not effectively removed before the next use, it will significantly affect the purity of subsequent melting, reduce heat transfer efficiency, shorten the service life of the crystallizer and the base pad itself, and pose a potential risk to the product quality of the final forging.

[0004] Currently, the industry still heavily relies on traditional manual cleaning methods for removing such stubborn residues. This involves operators using handheld tools such as hammers, chisels, and angle grinders to hammer and grind for extended periods. This method is not only inefficient and extremely labor-intensive, requiring highly skilled workers and posing serious personal safety hazards, but more importantly, it generates large amounts of diffuse metallic and non-metallic dust during mechanical grinding, causing severe environmental pollution, harming the respiratory health of operators, and contradicting increasingly stringent environmental regulations. Furthermore, the cleanliness achieved through manual cleaning is inconsistent and can easily damage the mat itself.

[0005] Therefore, there is an urgent need for a specialized cleaning equipment for ingot bottom pads that can achieve automation, high efficiency, low dust, and uniform and stable cleaning effect, so as to completely replace the outdated manual operation, solve the long-standing pain points in the industry, and meet the multiple needs of modern production for environmental protection, efficiency and humanization.

Detailed Implementation

[0022] To make the objectives, features, and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described below are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, the same or similar reference numerals may be used in the drawings to refer to the same or similar elements in different embodiments, and descriptions of the same or similar elements in different embodiments, as well as descriptions of prior art elements, features, effects, etc., may be omitted.

[0023] Reference Figures 1-7 This invention provides a water curtain-protected high-pressure water jet cleaning device for ingot bottom pads.

[0024] Specifically, the water curtain-protected high-pressure water jet cleaning device for ingot base pads includes a collection box 2, a vision recognition system 10, a controller (not shown), an actuator 9, a water curtain-protected high-pressure water jet nozzle assembly 6, a high-pressure water pump 7, and a water treatment tank 5. The collection box 2 is equipped with load-bearing bars 2-6 for placing the ingot base pad 3. The vision recognition system 10 is positioned above the collection box 2. The water curtain-protected high-pressure water jet nozzle assembly 6 is mounted on the actuator 9, which drives the assembly to move along a set trajectory. The assembly is connected to the high-pressure water pump 7. The assembly includes a rotary high-pressure water jet nozzle 6-1 and a water curtain protection component. The rotary high-pressure water jet nozzle 6-1 is positioned at the center of the water curtain protection component. The water jet nozzle 6-1 generates a high-pressure water jet to clean the ingot base pad 3 located in the collection box 2. The water curtain protection component generates a water curtain on the outer periphery of the rotating high-pressure water jet nozzle 6-1 to shield internal splashes and water mist. The water treatment tank 5 connects the collection box 2 and the high-pressure water pump 7 to achieve filtration, cleaning, and automatic circulation of the liquid in the collection box 2. During operation, the vision recognition system 10 identifies the position and size of the ingot base pad 3 relative to the collection box 2. The controller plans the movement trajectory of the water curtain protection high-pressure water jet nozzle assembly 6 based on the recognition data of the vision recognition system 10. The high-pressure water pump 7 provides high-pressure water to the water curtain protection high-pressure water jet nozzle assembly 6. At the same time, the actuator 9 drives the water curtain protection high-pressure water jet nozzle assembly 6 to move along the planned trajectory, spraying high-pressure water jets and water curtains to clean the ingot base pad 3.

[0025] In some embodiments, the water curtain protective component includes a main sleeve 6-11, a high-speed sleeve 6-10, a medium-speed sleeve 6-9, and a low-speed sleeve 6-8 nested sequentially from the inside out. The bottom ends of the main sleeve 6-11, high-speed sleeve 6-10, medium-speed sleeve 6-9, and low-speed sleeve 6-8 are flush and their heights decrease sequentially. A high-speed inlet 6-3, a medium-speed inlet 6-9, and a low-speed inlet 6-8 are respectively provided near the top of the outer wall of the high-speed sleeve 6-10, medium-speed sleeve 6-9, and low-speed sleeve 6-8. Inlet 6-5 and low-speed inlet 6-7; the upper part of the inner wall of high-speed sleeve 6-10 forms a high-speed pressure stabilizing cavity 6-2 with the outer wall of main sleeve 6-11, and the lower part of the inner wall of high-speed sleeve 6-10 forms a high-speed outlet 6-12 with the outer wall of main sleeve 6-11; high-speed inlet 6-3, high-speed pressure stabilizing cavity 6-2, and high-speed outlet 6-12 are connected to form a high-speed flow channel; the upper part of the inner wall of medium-speed sleeve 6-9 forms a medium-speed flow channel with the outer wall of high-speed sleeve 6-10. The lower part of the inner wall of the medium-speed sleeve 6-9 and the outer wall of the high-speed sleeve 6-10 form a medium-speed outlet 6-13. The medium-speed inlet 6-5, the medium-speed pressure-stabilizing chamber 6-4, and the medium-speed outlet 6-13 are connected to form a medium-speed flow channel. The upper part of the inner wall of the low-speed sleeve 6-8 and the outer wall of the medium-speed sleeve 6-9 form a low-speed pressure-stabilizing chamber 6-6. The lower part of the inner wall of the low-speed sleeve 6-8 and the outer wall of the medium-speed sleeve 6-9 form a low-speed outlet 6-14. Liquid inlet 6-7, low-speed pressure stabilizing chamber 6-6, and low-speed outlet 6-14 are connected to form a low-speed flow channel; high-pressure water flows through high-speed inlet 6-3, medium-speed inlet 6-5, and low-speed inlet 6-7, respectively, and through high-speed pressure stabilizing chamber 6-2, medium-speed pressure stabilizing chamber 6-4, and low-speed pressure stabilizing chamber 6-6, respectively, and from high-speed outlet 6-12, medium-speed outlet 6-13, and low-speed outlet 6-14, respectively forming three cylindrical water curtains with different flow velocities coaxial with the rotating high-pressure water jet nozzle 6-1.

[0026] In some embodiments, the heights of the high-speed voltage regulating chamber 6-2, the medium-speed voltage regulating chamber 6-4, and the low-speed voltage regulating chamber 6-6 decrease sequentially, their widths increase sequentially, and their volumes increase sequentially; the distances between the high-speed outlet 6-12, the medium-speed outlet 6-13, and the low-speed outlet 6-14 and the high-speed voltage regulating chamber 6-2, the medium-speed voltage regulating chamber 6-4, and the low-speed voltage regulating chamber 6-6 increase sequentially; and the ratio of the widths of the high-speed outlet 6-12, the medium-speed outlet 6-13, and the low-speed outlet 6-14 is 1:1.5:2.

[0027] Specifically, the high-speed channel is located at the innermost part of the water curtain protective component. Its longer and smaller high-speed pressure-stabilizing chamber 6-2 and its finer and shorter high-speed outlet 6-12 allow the water to flow out at a higher velocity. The response time of the water flowing out of the small high-speed pressure-stabilizing chamber 6-2 is also the shortest, resulting in the fastest water output speed. The flow velocity at the high-speed outlet 6-12 is the fastest among the three channels. The high-speed water flow can maximally reduce the splashing of water droplets and residues generated by the impact of the internal high-pressure jet on the surface, minimizing the kinetic energy of the splashes moving outward in the shortest possible time. The outermost low-speed channel has the largest low-speed pressure-stabilizing chamber 6-6 among the three channels, and the gap of the low-speed outlet 6-14 is also the largest. It also has the largest water flow rate. The function of the low-speed channel, located on the outermost side, is to block all splashes through the water curtain barrier with the largest flow rate. The large flow rate of the water curtain can completely prevent the water mist generated by the internal high-pressure jet from overflowing, and the large flow rate of water can wash away the residues on the surface of the material. The medium-speed flow channel is located between the innermost high-speed flow channel and the outermost low-speed flow channel; under the action of the triple water curtain barrier, it can completely prevent water droplets and residues from splashing outwards, as well as the generation of water mist, and can also play a certain role in sound insulation.

[0028] While a single-layer water curtain can block most of the water mist, the high-speed jet splash will tear it apart, failing to completely block flying debris and water mist. Therefore, the momentum and mass of a single-layer water curtain are insufficient to effectively attenuate the enormous momentum of the high-speed jet. Adding another water curtain significantly reduces the kinetic energy of the flying debris and water droplets when the internal splash impacts the second layer after passing through the first. However, the stability of the second layer is compromised by this disturbance, causing some water mist to still overflow. Thus, another layer of water curtain is added. In this configuration, three layers of water curtains and a progressively increasing flow rate effectively protect against splashes and water mist. The high-speed flow rate in the inner layer significantly reduces the momentum of the splashed debris and water droplets. The second layer further attenuates and guides the momentum, while the third layer provides final shielding and sealing. This differentiated and synergistic function of the three water curtains, working together to form a highly efficient energy attenuation and shielding device.

[0029] In some embodiments, the main sleeve 6-11, the high-speed sleeve 6-10, the medium-speed sleeve 6-9, and the low-speed sleeve 6-8 are connected by threads in sequence, and the rotary high-pressure water jet nozzle 6-1 is installed from the top of the main sleeve 6-11 to the center of the main sleeve 6-11, and the rotary high-pressure water jet nozzle 6-1 is fixed to the top of the main sleeve 6-11 by bolts.

[0030] Specifically, the rotary high-pressure water jet nozzle 6-1 uses existing technology, which will not be elaborated here.

[0031] In some embodiments, a booster pump 4, a fourth pressure regulating valve 4-1, and a fourth pressure gauge 4-2 are provided before the inlet of the rotary high-pressure water jet nozzle 6-1; a first pressure regulating valve 7-3, a first throttle valve 7-4, and a first pressure gauge 7-5 are provided before the high-speed inlet 6-3; a second pressure regulating valve 7-6, a second throttle valve 7-7, and a second pressure gauge 7-8 are provided before the medium-speed inlet 6-5; and a third pressure regulating valve 7-9, a third throttle valve 7-10, and a third pressure gauge 7-11 are provided before the low-speed inlet 6-7. The first throttle valve 7-4, the second throttle valve 7-7, and the third throttle valve 7-10 are adjusted so that the flow rate ratio of the high-speed flow channel, the medium-speed flow channel, and the low-speed flow channel is 1:2.25:4.

[0032] In some embodiments, the system also includes a storage tank 8, which is connected to a high-pressure water pump 7. An overflow valve 7-1 and a total pressure gauge 7-2 are provided at the outlet of the high-pressure water pump 7. When the pressure of the high-pressure water pump 7 detected by the total pressure gauge 7-2 is lower than the set pressure, the storage tank 8 supplies liquid to the water curtain protective high-pressure water jet nozzle assembly 6.

[0033] In some embodiments, a clearance notch is provided on one side wall of the collection box 2, and a spring curtain assembly is provided at the clearance notch. A guide channel 2-7 is provided in the collection box 2 corresponding to the clearance notch, and the height of the end of the guide channel 2-7 near the clearance notch is greater than the height of the end away from the clearance notch. A drain channel 2-8 is provided on the side of the collection box 2 opposite to the clearance notch, and the drain channel 2-8 is connected to a drain outlet 2-5, which is connected to the water treatment tank 5.

[0034] Specifically, there are multiple load-bearing bars 2-6, and guide grooves 2-7 are also provided between adjacent load-bearing bars 2-6.

[0035] In some embodiments, the spring curtain assembly includes a main rod 2-2, a spring push rod 2-1, a folding curtain 2-3, and a guide rail 2-4. Guide rails 2-4 are provided on both sides of the clearance notch. The main rod 2-2 is straddling the clearance notch and its two ends are respectively provided in the guide rails 2-4. The top of the folding curtain 2-3 is connected to the main rod 2-2, and the bottom is connected to the bottom of the clearance notch. The spring push rod 2-1 is connected to the main rod 2-2 and drives the main rod 2-2 to move up and down along the guide rails 2-4.

[0036] Specifically, the spring curtain assembly provides space for the forklift forks when loading materials. When the forklift forks, carrying the ingot base pad 3, place the ingot base pad 3 from top to bottom on the load-bearing bar 2-6 of the manifold 2, the forklift forks avoid interference with the outer wall of the manifold 2 under the space provided by the clearance notch after the spring curtain assembly moves down. When the forklift forks are placed and withdrawn, the spring curtain assembly returns to its original position by relying on the spring push rod 2-1. The clearance notch of the manifold 2 protects the water flow generated during processing from overflowing.

[0037] In some embodiments, the system further includes a ground rail 1, a manifold 2 disposed on the ground rail 1 and movable along the ground rail 1, and the ground rail 1 having a loading / unloading position, a detection position, and a cleaning position arranged sequentially from front to back. When the manifold 2 is in the loading / unloading position, the ingot base pad 3 is placed in the manifold 2 or removed by a forklift. When the manifold 2 is in the detection position, the position of the ingot base pad 3 relative to the manifold 2 and the size of the ingot base pad 3 are identified by the vision recognition system 10, and the cleaning detection is performed to identify whether the ingot base pad 3 is clean. When the manifold 2 is in the cleaning position, the ingot base pad 3 is cleaned by the water curtain protective high-pressure water jet nozzle assembly 6.

[0038] In some embodiments, the visual recognition system 10 includes a recognition camera and a mounting bracket, the mounting bracket spanning above the detection position of the ground rail 1, and the recognition camera fixed in the middle of the mounting bracket; used to identify the position of the ingot base pad 3 relative to the collector box 2, the size of the ingot base pad 3, and whether the surface of the ingot base pad 3 is clean.

[0039] Specifically, the identification camera can be an existing identification camera that can identify the position of the ingot base pad 3 relative to the collector box 2, the size of the ingot base pad 3, and whether the surface of the ingot base pad 3 is clean. There are no restrictions here.

[0040] Specifically, the actuator 9 is a robotic arm; any existing robotic arm that can drive the water curtain protective high-pressure water jet nozzle assembly 6 to move along a set trajectory is acceptable, and there are no restrictions here.

[0041] Specifically, the water treatment tank 5 can use existing water treatment technology to filter and clean the liquid after cleaning in the collection tank 2; there are no restrictions here.

[0042] The working process of the water curtain protective high-pressure water jet cleaning device for the ingot bottom pad 3 according to an embodiment of the present invention is as follows: Step 1: The manifold 2 is moved to the loading / unloading position, and the forklift places the ingot bottom pad 3 to be cleaned on the load-bearing strips 2-6 inside the manifold 2.

[0043] Step 2: The collector box 2 moves along the ground rail 1 to the detection position, located directly below the vision recognition system 10; the recognition camera is activated, and it acquires the surface image of the ingot base pad 3. The feature analysis is performed through the image processing algorithm to identify the circular outline of the ingot base pad 3, and calculates the precise center coordinates, radius and thickness data of its center in the collector box 2. The recognition data is then transmitted to the controller in real time.

[0044] Step 3: Based on the recognition data provided by the vision recognition system 10, the controller plans the optimal cleaning path for the robotic arm; drives the robotic arm equipped with the water curtain protective high-pressure water jet nozzle assembly 6 to move, so that it starts from the calculated center and performs line-by-line scanning cleaning of the entire surface of the ingot base pad 3 along the bow-shaped trajectory at preset intervals.

[0045] Key cleaning parameters can be set as follows: the pressure range of the rotary high-pressure water jet nozzle 6-1 is 120MPa-300MPa (adjustable according to the stubbornness of the residue), and the flow rate is 5-10 L / min; the pressure of the water curtain protective component is 30MPa-60MPa, the flow rate is 40-60L / min, the moving linear speed of the nozzle is between 100mm / s and 300mm / s, the row spacing of the bow-shaped trajectory is 3mm-8mm, and the target distance between the water curtain protective component and the surface of the ingot base pad 3 is 5mm-10mm, to ensure full coverage and efficient cleaning effect.

[0046] Step 4: During the cleaning process, all wastewater, stripped residue, and water mist generated are effectively sealed in the collection box 2; the waste liquid carrying the residue is discharged through the drain port at the bottom of the collection box 2 and enters the water treatment tank 5. After multi-stage filtration to remove most of the solid particles, it undergoes deep purification. The treated clean water is then transported to the high-pressure water pump 7 to achieve closed-loop utilization of water resources.

[0047] Step 5: After cleaning, the manifold 2 carries the ingot base pad 3 back to the inspection position for a second inspection of the cleaning quality; the vision recognition system 10 performs a second imaging of the surface of the ingot base pad 3, and judges whether there are still alloy residues by comparing the images before and after cleaning or by intelligent recognition algorithms; if a local area that has not been thoroughly cleaned is identified, the vision recognition system 10 locates the coordinates of the residual area and instructs the robotic arm to move to the position for fixed-point fine cleaning through the controller; if it is confirmed that the entire surface is completely clean, the manifold 2 automatically moves to the loading and unloading position; the forklift performs the unloading operation to remove the cleaned ingot base pad 3, completing the entire automated cleaning process.

[0048] In summary, the water curtain-protected high-pressure water jet cleaning device for ingot base pads in this embodiment of the invention uses a water curtain-protected high-pressure water jet nozzle assembly 6 to generate high-pressure water jets and a water curtain. The high-pressure water jet impacts and removes stubborn residues while avoiding damage to the ingot base pad 3. The water curtain isolates the cleaning operation point from the external environment, suppresses the source of dust, and simultaneously removes the water mist generated during the operation. Under high flow rates, it prevents alloy residues peeled off from the base pad from splashing, achieving a dust-free cleaning process. The collection box 2, together with the ground rail 1 and forklift, realizes automatic feeding and positioning of the ingot base pad. It uses machine vision technology to intelligently identify the cleaning path and stubborn stain areas. Finally, the controller drives the actuator 9 to complete the entire process from feeding, identification, positioning, cleaning to unloading. The wastewater and residue after cleaning are also collected together, and after treatment, the water is reused for cleaning, achieving efficient, clean, and intelligent cleaning of the ingot base pad 3.
