Rotary lift shower based on a rolling mill cleaning machine

Abstract

This invention relates to the field of metallurgical equipment technology and discloses a rotary lifting and rinsing device based on a rolling mill cleaning machine. A rotary drive motor on a fixed rod, via gear meshing, drives the workpiece-bearing rotating disc to rotate coaxially between a relatively stationary fixed spray ring and a bottom fixed bearing disc, achieving 360° uniform circumferential rinsing of the rolling mill components. Then, a lifting drive hydraulic rod at the lower end of the bottom fixed bearing disc drives a lifting support rod, which passes through the positioning holes on both the bottom fixed bearing disc and the workpiece-bearing rotating disc, lifting the workpiece-bearing support disc along with the rolling mill components as a whole. This completely separates the bottom of the workpiece from the bearing surface, creating an open cleaning gap. Simultaneously, the high-pressure cleaning fluid's own energy drives the adaptive oscillating spray nozzle assembly inside the fixed spray ring to form a swirling high-pressure jet and high-frequency dynamic sweeping spray, covering the inner holes, grooves, and other irregularly shaped complex structures of the rolling mill components, significantly improving cleaning efficiency and cleanliness consistency.

Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment manufacturing technology, and in particular to a rotary lifting and rinsing device based on a rolling mill cleaning machine. Background Technology

[0002] With the increasing demands for surface quality and dimensional accuracy of high-precision metal sheets, strips, and profiles from industries such as high-end equipment manufacturing, automobiles, new energy, and electronic information, the surface cleanliness of the core functional components of rolling mills, as the core heavy equipment for metal plastic forming, has become a key indicator determining the yield, quality grade, and operational reliability of rolled products. Under heavy-load, high-speed, and lubricated rolling conditions, the surfaces of the core components of rolling mills continuously accumulate contaminants such as rolling oil, cold rolling emulsion, metal filings, high-temperature oxide scale, and tar stains. Without deep cleaning, this can lead to irreversible defects such as scratches on the working surfaces of the rolls and pits / scratches / dents on the strip surface, resulting in the scrapping of the entire coil. It can also cause major equipment accidents such as abrasive wear of bearing raceways, roll neck seizure, gearbox tooth breakage, and hydraulic pipeline blockage, significantly shortening equipment lifespan and increasing unplanned downtime and maintenance costs. Therefore, offline deep cleaning of the core components of rolling mills has become an indispensable key process in modern rolling production lines.

[0003] The above-mentioned and existing related technologies often have the following defects: the spray mechanism of the existing rolling mill component cleaning device mostly uses fixed angle nozzles, which cannot adaptively sweep and cover the complex mating surfaces such as grooves and inner holes of the workpiece. This results in permanent cleaning blind spots at the bottom support position and complex structure of heavy rolling mill components, poor cleaning cleanliness consistency, the need for manual secondary cleaning, low cleaning efficiency, and high labor intensity for operators. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology of the existing mill component cleaning device spray mechanism mostly uses fixed angle nozzles, which cannot adaptively sweep and cover the complex mating surfaces such as grooves and inner holes of the workpiece.

[0008] Preferably, the upper end face of the bottom support fixing plate and the lower end face of the fixing spray ring are both coaxially provided with annular grooves. The groove size of the annular groove matches the edge size of the upper and lower ends of the workpiece support rotating plate. The upper and lower ends of the workpiece support rotating plate are respectively embedded in the annular grooves on the corresponding sides.

[0009] Preferably, the spray nozzle assembly includes an adapter, which is rotatably connected to the inner wall of the fixed spray ring via a sealed bearing. The outer wall of the adapter is connected to a swing spray main pipe, and the end of the swing spray main pipe is rotatably connected to a swirling conical nozzle via a rotary sealing joint. Multiple sets of guide fins are fixed to the inner wall of the swirling conical nozzle, and a counterweight block is fixed to the front end of the nozzle via a counterweight linkage connecting rod.

[0010] Preferably, multiple sets of drainage grooves are formed through the disc body of the workpiece-bearing rotating disc and the disc body of the bottom-bearing fixed disc.

Detailed Implementation

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figure 1-2 As shown, the present invention provides a technical solution: a rotary lifting and rinsing device based on a rolling mill cleaning machine, including a cleaning device 1. The cleaning device 1 is the core enclosed operating body of the device, providing a sealed rinsing operation space for the rolling mill components. A mixing tank 2 is connected to one side of the cleaning device 1. The mixing tank 2 mixes the spray cleaning liquid and sends the mixed liquid into the cleaning device 1 through a high-pressure water pump to complete the cleaning of the rolling mill components. A treatment tank 3 is set on one side of the mixing tank 2. The treatment tank 3 recovers the cleaning waste liquid discharged from the cleaning device 1, purifies it, and returns it to the mixing tank 2 for recycling.

[0020] Reference Figure 1-3 As shown in this embodiment: the cleaning device 1 includes a cleaning tank 11, which is a vertical, enclosed rectangular cavity with a Q235B steel welded load-bearing frame and an inner wall lined with 316L stainless steel anti-corrosion lining. This provides a sealed, anti-corrosion space for the rinsing operation and a mounting base for internal components. A rectangular opening for workpiece entry and exit is provided on the front of the cleaning tank 11. A protective door 12 is installed on one side of the opening via a heavy-duty hinge. The protective door 12 is a sealed door matching the opening, with a water-swellable waterproof sealing strip embedded on the inside. During operation, the opening is closed to isolate the inner cavity from the outside, preventing cleaning fluid splashing and noise diffusion. A safety interlock switch is provided between the protective door 12 and the cleaning tank 11. The switch signal terminal is electrically connected to the device's main control system. When the door is opened, all power sources are cut off. Multiple spray assembly 1s are fixed to the top of the inner cavity of the cleaning tank 11. 3. The spray assembly 13 is connected to the high-pressure liquid supply end of the mixing box 2, outputting a high-pressure cleaning jet to perform rinsing on the rolling mill components below. A filter screen 111 is horizontally fixed at the lower end of the inner cavity of the cleaning box 11 and below the spray assembly 13. The filter screen 111 is a 304 stainless steel perforated screen, and its edge is fixed to the load-bearing frame of the side wall of the cleaning box 11 by a detachable bolt strip. It performs primary filtration of the falling waste liquid, intercepting large particles of iron filings, oxide scale, and oil stains, and preventing impurities from clogging the downstream pipeline. A mounting assembly 14 is slidably installed on the side wall of the inner cavity of the cleaning box 11 and above the filter screen 111 along the depth direction. The sliding stroke of the mounting assembly 14 covers the inner working area of ​​the cleaning box 11 and the external loading and unloading area, carrying the rolling mill components to be cleaned. The workpiece is moved to the station position below the spray assembly 13 for positioning, and the cleaning is completed. The cleaned workpiece is then removed from the cleaning box 11.

[0021] The filter screen 111 has a mesh size of 50-80 mesh and a tilted design. The end near the back of the cleaning tank 11 is lower than the end near the protective door 12, which guides the filtered waste liquid to the collection tank at the bottom of the cleaning tank 11 to prevent the waste liquid from accumulating and breeding oil stains. The filter screen 111 adopts a detachable installation structure, which is convenient for regular cleaning to intercept impurities, prevent filter screen blockage, and facilitate maintenance and replacement.

[0022] Reference Figure 3-4 As shown in this embodiment, two sets of heavy-duty linear guides 112 extending along the workpiece feeding and discharging direction are symmetrically fixed on the inner walls of both sides of the inner cavity of the cleaning tank 11. The slider at the sliding end of the heavy-duty linear guide 112 is fixedly connected to the side fixing rod 1121 of the mounting component 14, driving the mounting component 14 to complete the switching of the feeding and discharging station. An auxiliary support slide rail 113 is fixed on the load-bearing frame at the bottom of the inner cavity of the cleaning tank 11 along the direction parallel to the heavy-duty linear guide 112. The auxiliary support slide rail 113 is slidably connected to the bottom of the mounting component 14, providing sliding support and displacement guidance for the mounting component 14, and preventing heavy-duty sinking and jamming.

[0023] Reference Figure 4-6 As shown in this embodiment: the upper end face of the auxiliary support slide rail 113 has an axially recessed slide groove 1131. The mounting assembly 14 includes a mounting plate 141 for supporting and positioning the rolling mill components to be cleaned. The lower end face of the mounting plate 141 is fixed with an anti-overturning stabilizing block 143 to improve the structural rigidity and anti-overturning capacity of the mounting plate under heavy load. The lower end face of the mounting plate 141 is also fixed with a guide sliding pulley 142 that is adapted to the size of the slide groove 1131. The guide sliding pulley 142 is embedded in the slide groove 1131 and slides back and forth along the groove to maintain its horizontal stability during the movement of the mounting assembly 14 and prevent radial displacement and shaking.

[0024] Reference Figure 4-7 As shown in this embodiment: a fixed rod 1121 is fixedly connected to the slider of the heavy-duty linear guide 112, providing a mounting base and displacement guide for the transmission components. The fixed rod 1121 is fixedly connected to the side of the mounting plate 141. A linear drive motor 1122 is fixed to the outer wall of the fixed rod 1121, providing driving power for the loading and unloading of the mounting plate 141 and the switching of work positions. The driving end of the linear drive motor 1122 passes through the fixed rod 1121 and is coaxially fixed with a linear drive gear 1123. The linear drive gear 1123 is accommodated in the mounting groove opened inside the fixed rod 1121, forming protection and radial limit for the gear, preventing transmission shaking and tooth dislodgement. A transmission rack is fixed to the inner wall of the cleaning box 11 along the extension direction of the heavy-duty linear guide 112. The linear drive gear 1123 meshes with the transmission rack, and the mounting plate 141 moves smoothly along the guide rail through gear transmission.

[0025] Reference Figure 5-9As shown, in this embodiment: the placement tray 141 includes a workpiece bearing rotating tray 1411, an integrally formed transmission meshing gear ring 1412 on the outer ring sidewall of the workpiece bearing rotating tray 1411, a rotary drive motor 1124 fixed on the upper side of the fixing rod 1121, a rotary drive gear 1125 coaxially fixed at the drive end of the rotary drive motor 1124, the rotary drive gear 1125 meshing with the transmission meshing gear ring 1412 to achieve rotary transmission, and a fixed spray ring 1413 coaxially rotatably mounted on the upper end of the workpiece bearing rotating tray 1411, the left and right ends of the fixed spray ring 1413 being fixedly connected to the two side fixing rods 1121. The bottom support plate 1415 is coaxially mounted on the lower end of the workpiece bearing rotating disk 1411. The left and right ends of the bottom support plate 1415 are fixed to the two side fixing rods 1121. The rotary drive motor 1124 drives the rotary drive gear 1125 to rotate. Through meshing transmission, the workpiece bearing rotating disk 1411 rotates synchronously. The fixed spray ring 1413, the bottom support plate 1415 and the fixing rods 1121 are fixed relative to each other. The workpiece bearing rotating disk 1411 can rotate freely coaxially between the two, driving the rolling mill components on it to rotate synchronously. Together with the spray mechanism, it can achieve full circumferential cleaning without dead angles.

[0026] Reference Figure 5-9 As shown in this embodiment: the outer wall of the fixed spray ring 1413 is connected to the high-pressure liquid supply hose 1414. The upper end of the high-pressure liquid supply hose 1414 is connected to the liquid outlet end of the spray assembly 13. The high-pressure liquid supply hose 1414 is a telescopic flexible structure that adapts to the movement stroke of the mounting plate 141 to prevent the pipeline from being pulled and broken. Multiple sets of directional spray heads 131 are evenly distributed and fixed on the lower end face of the spray assembly 13. The spray direction of the multiple sets of directional spray heads 131 is all pointing towards the axis of the mounting plate 141, so as to directionally and high-pressure wash the top area such as the upper end face and inner hole of the rolling mill component, and achieve full coverage of the top area in conjunction with the rotation of the workpiece.

[0027] Reference Figure 5-9 As shown in this embodiment: the lower end face of the bottom bearing fixed plate 1415 is fixedly connected to the mounting base of the guide sliding pulley 142, and the lower end face of the bottom bearing fixed plate 1415 is also fixedly connected to the upper end of the anti-overturning stabilizing block 143. The smooth sliding of the placement plate 141 is achieved through the sliding cooperation between the guide sliding pulley 142 and the auxiliary support slide rail 113. The anti-overturning stabilizing block 143 enhances the rigidity of the heavy-duty structure of the placement plate and prevents overturning and shaking.

[0028] Reference Figure 5-9As shown in this embodiment: A circular groove 1416 is coaxially formed on the upper end face of the bottom bearing fixed plate 1415 and the lower end face of the fixed spray ring 1413. The dimensions of the circular groove 1416 match the dimensions of the upper and lower edges of the workpiece bearing rotating plate 1411. The upper and lower ends of the workpiece bearing rotating plate 1411 are respectively embedded in the corresponding side circular groove 1416, which radially limits and axially positions the rotation of the workpiece bearing rotating plate 1411, ensuring coaxiality of rotation and preventing radial offset and axial movement. Multiple sets of drainage grooves 1417 are formed through the workpiece bearing rotating plate 1411 and the bottom bearing fixed plate 1415, guiding the waste liquid after rinsing downwards to the filter screen 111 for primary filtration, preventing waste liquid accumulation and secondary contamination of the workpiece, and assisting in the interception of large particulate impurities.

[0029] Reference Figure 5-9 As shown in this embodiment: two sets of driving hydraulic rods 144 are symmetrically fixed on the lower end face of the bottom bearing fixed plate 1415. The vertical driving ends of the two sets of driving hydraulic rods 144 are coaxially fixed to the support rod 1441. The support rod 1441 can penetrate upward through the plate body of the bottom bearing fixed plate 1415. A photoelectric positioning sensor is fixed on the lower end face of the fixed spray ring 1413. A sensing plate matching the positioning sensor is fixed on the upper end face of the workpiece bearing rotating plate 1411 to detect the rotation position of the workpiece bearing rotating plate 1411. When it is necessary to lift the rolling mill component to clean the bottom, the control system first stops the rotation drive motor 1124, so that the workpiece bearing rotating plate 1411 stops rotating. The positioning sensor detects the workpiece. When the rotating disk 1411 rotates to the designated position, it sends a signal to the control system. The control system then activates the hydraulic rod 144 to drive the support rod 1441 to extend upward, so that the support rod 1441 is inserted into the positioning hole 1418 on the workpiece rotating disk 1411. After the support rod 1441 continues to rise, it abuts against the lower end face of the upper workpiece support disk 1419, lifting the entire mill component placed on the workpiece support disk 1419 upward. This creates a cleaning gap between the bottom of the mill component and the workpiece rotating disk 1411. The spray nozzle assembly 145 simultaneously sprays the upper end face, circumferential surface, and bottom gap of the mill component, achieving a thorough cleaning of the entire surface of the workpiece without any dead angles.

[0030] Reference Figure 5-9 As shown in this embodiment: a workpiece bearing support plate 1419 is coaxially and movably mounted on the upper end face of the workpiece bearing rotating disk 1411. Two sets of positioning holes 1418 are symmetrically opened through the workpiece bearing rotating disk 1411. The diameter and position of the two sets of positioning holes 1418 correspond one-to-one with the outer diameter and position of the two sets of support rods 1441, ensuring that the support rods 1441 can accurately pass through the positioning holes 1418, thereby achieving stable lifting of the workpiece bearing support plate 1419. The lower end face of the workpiece bearing support plate 1419 is provided with a positioning groove that matches the support rods 1441 to prevent the support plate from shifting horizontally during lifting.

[0031] Reference Figure 5-9 As shown in this embodiment: multiple sets of spray nozzle assemblies 145 are uniformly rotated around the inner sidewall of the fixed spray ring 1413. The liquid inlet end of the spray nozzle assembly 145 is connected to the internal flow channel of the fixed spray ring 1413, and is connected to the liquid supply system of the spray assembly 13 through the high-pressure liquid supply hose 1414 to realize the continuous supply of high-pressure cleaning fluid.

[0032] Reference Figure 9-11 As shown in this embodiment: the spray nozzle assembly 145 includes an adapter 1451. Multiple sets of liquid diversion holes 1452 are opened through the side wall of the adapter 1451 to realize the diversion and conduction of cleaning liquid. The adapter 1451 is rotatably connected to the inner side wall of the fixed spray ring 1413 through a sealed bearing and can rotate freely around its own axis. The outer side wall of the adapter 1451 is connected to and fixed to the swing spray main pipe 1453. The end of the swing spray main pipe 1453 away from the adapter is rotatably set with a swirling conical nozzle 1454 through a rotary sealing joint. Multiple sets of guide fins 1455 are evenly fixed along the circumference on the inner side wall of the swirling conical nozzle 1454. A counterweight linkage connecting rod 1456 is coaxially fixed at the front axis of the swirling conical nozzle 1454. A counterweight block 1457 is fixed at one end of the counterweight linkage connecting rod 1456 that extends into the interior of the adapter 1451.

[0033] During the rinsing operation, the spray assembly 13 uses directional spray heads 131 to provide directional high-pressure rinsing to the top of the rolling mill components. Part of the high-pressure cleaning fluid flows into the internal flow channel of the fixed spray ring 1413 through the high-pressure supply hose 1414, and is then diverted into the adapter 1451 of the multiple spray head assemblies 145. The high-pressure water flow enters the oscillating spray main pipe 1453 and impacts the guide fins 1455 within the swirling conical nozzle 1454. This causes the swirling conical nozzle 1454 to rotate at high speed around its own axis, forming a swirling high-pressure jet, enhancing the scouring force on the workpiece surface for oil and iron filings. Furthermore, the water flow... The reaction force generated by the impact guide fin 1455 drives the entire adapter 1451 to rotate circumferentially around its own axis, causing the counterweight 1457 to rotate synchronously with the adapter and generate centrifugal force, which drives the swing spray main pipe 1453 to swing back and forth at high frequency, realizing dynamic sweeping spraying, covering the cleaning dead corners such as grooves, inner holes, and mating surfaces of the rolling mill components. When the rolling mill components are lifted to the same height as the spray nozzle assembly 145 by the driven hydraulic rod 144, the swirling high-pressure jet washes the bottom gap and lower end face of the rolling mill components, and with the directional flushing of the directional spray head 131, the contaminants on the entire surface of the rolling mill components are removed simultaneously.

[0034] Reference Figure 1-2As shown in this embodiment: the mixing tank 2 is a closed horizontal box, which is fixed to one side of the cleaning device 1 by a support base. The inner cavity of the mixing tank 2 is divided into a liquid preparation chamber and a liquid supply chamber by an anti-corrosion partition. The top of the liquid preparation chamber is equipped with a clean water inlet, a cleaning agent injection port, and a corrosion inhibitor injection port. The liquid preparation chamber is equipped with a stirring component to evenly mix the clean water and the cleaning agent to form a cleaning mixture with a stable concentration. The liquid supply chamber is equipped with a high-pressure liquid supply pump group. The liquid outlet of the high-pressure liquid supply pump group is connected to the liquid inlet of the spraying component 13 through a pipeline to provide high-pressure power for the spraying operation.

[0035] Reference Figure 1-2 As shown in this embodiment: the treatment tank 3 is fixed to one side of the mixing tank 2 by a support base. The inlet of the treatment tank 3 is connected to the bottom collection tank of the cleaning tank 11 through a return pipeline with a lift pump. The outlet of the treatment tank 3 is connected to the liquid distribution chamber of the mixing tank 2 through a pipeline with a circulation pump. The inner cavity of the treatment tank 3 is divided into a sedimentation chamber, an oil-water separation chamber, and a fine filtration chamber along the direction of waste liquid flow. The recovered waste liquid is subjected to multi-stage purification treatment. After purification, the cleaning liquid is returned to the mixing tank 2 for recycling and reuse, thereby reducing the consumption of water resources and cleaning agents.

[0036] Working principle: During operation, the high-pressure cleaning fluid prepared in the mixing tank 2 is sent into the cleaning device 1, and the spray assembly 13 at the top of the cleaning tank 11 is cleaned. The rolling mill parts to be cleaned are placed on the workpiece bearing support plate 1419 of the placement assembly 14. The fixed rod 1121, which is fixed to the sliding guide structure on both sides of the inner cavity of the cleaning tank 11, drives the placement plate 141 to move along the depth direction of the cleaning tank 11 to the spraying position. The rotary drive motor 1124 on the fixed rod 1121 drives the rotary drive gear 1125 to rotate circumferentially. The rotating disk 1411 is driven by an integrally formed transmission gear ring 1412, which drives the workpiece-bearing rotating disk 1411 to rotate freely coaxially between the fixed spray ring 1413, which is rigidly connected to the fixed rods 1121 on both sides, and the bottom fixed disk 1415. This synchronously drives the rolling mill components on it to complete a 360° full-circumferential uniform rotation, cooperating with the spray assembly 13 to complete the initial circumferential and top washing of the workpiece. Simultaneously, high-pressure cleaning fluid is delivered through the high-pressure supply hose 1414 into the internal liquid flow channel of the fixed spray ring 1413, distributing... Multiple sets of adaptive oscillating spray nozzles 145, evenly arranged circumferentially on the inner wall of the rolling mill, utilize the energy of the high-pressure water flow to form a swirling high-pressure jet and a dynamic sweeping spray with high-frequency reciprocating oscillation. This precisely covers the complex, irregularly shaped structures such as the inner holes and grooves of the rolling mill components. When it is necessary to clean the bottom contact surface of the workpiece, two sets of lifting drive hydraulic rods 144, symmetrically fixed at the lower end of the bottom support plate 1415, drive the lifting support rods 1441 at their drive ends to extend upwards, penetrating the bottom support plate 1415 and the workpiece support rotating plate 141. After the symmetrically opened top rods pass through the positioning holes 1418, they lift the workpiece bearing support plate 1419 together with the rolling mill components upward, so that the bottom of the rolling mill components is completely separated from the workpiece bearing rotating plate 1411 and an open bottom cleaning gap is formed. With the help of the adaptive swing spray nozzle assembly 145, the entire surface of the workpiece is cleaned without dead angles. The waste liquid that falls after cleaning is sent to the treatment box 3 for multi-stage purification after primary filtration by the filter screen 111 at the lower end of the inner cavity of the cleaning box 11. The clean cleaning liquid after purification is returned to the mixing box 2 for recycling.
