Description

Technical Field

[0001] This invention relates to the field of ton container cleaning technology, and in particular to a high-pressure water jet cleaning mechanism for the inner wall of a scissor lifter. Background Technology

[0002] IBCs are widely used in the storage and transportation of materials in industries such as coatings, chemical raw materials, food additives, and daily chemical auxiliaries. After IBCs have been used for a long time to hold viscous and easily solidified materials, scale and residue are easily accumulated on the inner wall, the four corners, the rounded corners of the bottom, and the drain outlet. They need to be cleaned regularly and automatically using high-pressure water jet equipment. At present, the mainstream high-pressure cleaning devices for IBCs in the industry mainly rely on a lifting motor to drive the spray bar to move up and down, while a rotary motor drives the spray bar to rotate 360° to complete the washing operation of the inner wall of the IBC.

[0003] Existing traditional cleaning devices have a fixed installation angle for the spray bar and nozzles. After assembly, the tilt angle between the spray bar and the central spindle cannot be dynamically adjusted in real time. The entire cleaning process relies solely on two-dimensional motion: lifting and overall revolution. There is no composite motion involving real-time changes in the cleaning bar angle. Even if some equipment is equipped with a three-dimensional rotating nozzle, only the nozzle itself rotates slightly, while the main body tilt angle of the spray bar remains constant. This makes it impossible to achieve continuous and real-time adjustment of the overall spray bar angle, resulting in many insurmountable defects in actual production use. First, the spray trajectory is singular, and the irregularly shaped inner cavity of the ton container has a large number of cleaning blind spots, making it difficult to achieve the required level of cleanliness. The ton container is a composite irregularly shaped cavity with a square body, rounded corners, a conical bottom, and a bottom drain groove. The inner wall has flat surfaces, curved surfaces, and concave dead corners. The nozzle of the traditional fixed-angle spray bar always maintains a fixed tilt angle, and the high-pressure water jet can only form a single ring-shaped rinsing band. For irregularly shaped areas such as the rounded corners of the four corners of the container, the rounded corners of the bottom of the container, and the drain outlet, the water inflow angle cannot fit the curved surface, making it difficult to achieve the effect of vertical impact to remove the scale layer. It can only sweep across the surface of the dirt at an angle, and solidified clumps and viscous residues are very easy to remain. In order to achieve the cleaning standard, the equipment needs to repeatedly lift and circulate for rinsing. Some stubborn residues still need to be manually cleaned a second time in the container. Manual operation in a confined space poses safety hazards such as poisoning and high-pressure water impact.

[0004] Secondly, the nozzle-to-bucket target distance cannot be dynamically adjusted, resulting in unstable water flow impact energy and significant waste of water resources and energy. With the spray boom angle fixed, the distance between the nozzle and the inner wall of the bucket continuously changes during lifting and lowering: if the target distance is too large near the bucket opening, the high-pressure jet energy is significantly attenuated, resulting in insufficient descaling force; if the target distance is too small near the bottom of the bucket, the water flow concentrates and impacts localized areas. To ensure effective cleaning of corners and edges, the equipment must extend the rinsing time and increase the water supply pressure, significantly increasing water consumption per cleaning cycle and high-pressure pump energy consumption, lengthening the cleaning cycle, reducing production efficiency, and keeping water and electricity costs high for enterprises. Summary of the Invention

[0005] Therefore, it is necessary to provide a high-pressure water jet cleaning mechanism for the inner wall of a scissor lifter that can improve the cleaning quality of ton containers, addressing the aforementioned technical problems.

[0006] The present invention provides a high-pressure water jet cleaning mechanism for the inner wall of a scissor lifter, comprising a frame and guide rails fixed to the frame by bolts, and further comprising: A sliding frame is slidably mounted on one side of the guide rail and can move up and down relative to the frame. A linear module assembly is mounted on the sliding frame, and a pipe clamp is fixedly installed on one side of it; A positioning column is rotatably mounted below the sliding frame, and a connecting frame is fixedly mounted at its end; The guardrail is fixedly installed at the bottom of the frame to limit and align the ton container. The spray bar is axially and symmetrically mounted at both ends of the connecting frame, with a rotating spray head and a cylindrical nozzle respectively provided at each end; A high-pressure hose is connected between the rotary nozzle, the cylindrical nozzle, and the external high-pressure cleaning equipment. A swing assembly, mounted on the positioning post, is used to drive the spray bar to swing back and forth.

[0007] In one embodiment, the swing assembly includes a movable rod, the top of which is fixedly connected to the pipe clamp, and the other end of which movably passes through the positioning post and the connecting frame. Two spray bars are each fixedly provided with a gear at one end close to each other. The gear is rotatably disposed with the connecting frame. A rack is fixedly provided at the end of the movable rod, and the rack meshes with the gear for transmission.

[0008] In one embodiment, an end cap is detachably installed on the outside of the positioning post by bolts, the positioning post moves through the middle of the end cap, and through slots are axially symmetrically opened on both sides of the end cap for the high-pressure hose to pass through.

[0009] In one embodiment, the outer side of the end cap has a ring array of multiple slots, and a telescopic plate is movably disposed in the slot. The bottom of the telescopic plate is movably abutted against the opening of the ton container, and adjacent telescopic plates are connected by an elastic membrane.

[0010] In one embodiment, the inner surface of the end cap has a ring array of multiple sliding grooves, the number of which is the same as the number of slots. A sliding rod is movably disposed in each sliding groove, and the end of the sliding rod is fixedly connected to the telescopic plate.

[0011] In one embodiment, a rotating ring is rotatably mounted inside the end cap on the outer ring of the through groove. Multiple arc-shaped grooves are formed in an annular array on the rotating ring. A limit rod is fixedly provided at one end of the slide rod near the rotating ring, and the limit rod slides relative to the arc-shaped groove.

[0012] In one embodiment, a groove is provided on the outer ring of the telescopic plate, and a sinking plate is movably disposed in the groove. The inner sidewall of the sinking plate is movably fitted with the outer wall of the ton barrel opening.

[0013] In one embodiment, the telescopic plate has a through-groove on one side of the groove, and a movable plate is vertically and movably installed in the through-groove. The end of the movable plate is fixedly connected to one side of the sunken plate.

[0014] In one embodiment, a receiving groove is provided at the contact point between the telescopic plate and the inner surface of the end cap. A limiting plate is movably disposed in the receiving groove. One end of the limiting plate extends beyond the receiving groove, and the other end is fixedly connected to the inner wall of the end cap. An inclined groove is provided on the limiting plate. A vertical rod is fixedly disposed on one side of the movable plate, and the vertical rod is slidably embedded in the surface of the inclined groove.

[0015] In one embodiment, a movable groove is provided on the upper surface of the end cap, the movable groove is connected to the sliding groove, a movable block is movably disposed in the movable groove, and the end of the movable block is fixedly connected to the top of the slide rod.

[0016] In one embodiment, a vertical plate is fixedly installed on the upper surface of the end cap on one side of the moving groove, and multiple rotating rods are rotatably mounted in a horizontal linear array on the surface of the vertical plate. A sign is fixedly installed on the end of the rotating rod away from the moving groove.

[0017] In one embodiment, a swing rod is fixedly provided at the end of the rotating rod away from the signboard, and the swing rod is fixedly connected to the vertical plate by a torsion spring. A push rod is fixedly provided on one side of the moving block, and the push rod movably abuts against the swing rod.

[0018] The aforementioned high-pressure water jet cleaning mechanism for the inner wall of a scissor lifter uses a linear module to drive a rack and pinion transmission to achieve real-time switching of the spray bar angle. When the barrel is inserted, the spray bar is vertical to facilitate penetration through the barrel opening. During cleaning, the spray bar expands to increase the spray coverage area, dynamically adjusting the water inflow angle to eliminate dead corners on the barrel wall and improve descaling efficiency. A rotating ring, in conjunction with a sliding rod, drives multiple sets of telescopic plates to expand and retract synchronously, adapting to various barrel openings. An elastic membrane between the plates seals the expansion gaps, preventing water mist from overflowing and avoiding water vapor corrosion of the transmission and electrical components. One set of end caps can meet the sealing requirements of multiple barrel specifications, offering strong versatility. When the telescopic plates expand, the sinking plate moves down synchronously to wrap around the outer wall of the barrel opening, forming a double-layer seal with the telescopic plates, adapting to barrel opening size and roundness errors for better sealing. When retracting, the sinking plate retracts synchronously, and the lifting rod does not scrape the barrel opening, ensuring smooth and unobstructed operation. Relying on a moving block push rod and a torsion spring, the signboard pops out synchronously with the expansion of the telescopic plates and retracts synchronously, intuitively displaying the currently compatible barrel opening specifications.

[0027] The following is combined with Figures 1-14 This invention describes a high-pressure water jet cleaning mechanism for the inner wall of a scissor lifter.

[0028] like Figures 1-8 As shown, this embodiment discloses a high-pressure water jet cleaning mechanism for the inner wall of a scissor lifter, which is mainly used for automated high-pressure water cleaning of the inner walls of various ton containers. The whole machine includes a frame 1, a guide rail 2, a sliding frame 3, a linear module assembly 4, a positioning column 6, a connecting frame 7, a guardrail 9, a spray bar 10, a high-pressure hose 13, a swing assembly 8, and an adjustable sealing end cap 14 assembly adapted to multiple specifications of container openings.

[0029] The frame 1 serves as the base for the entire machine. The guide rail 2 is fastened to the frame 1 with bolts. The sliding frame 3 is slidably mounted on the side of the guide rail 2, allowing it to move smoothly up and down relative to the frame 1 along the guide rail 2. The linear module assembly 4 is fixedly mounted on the sliding frame 3. The side wall of the linear module assembly 4 is fixedly fitted with a pipe clamp 5, which is used to lock and fix the upper end of the movable rod 81. The positioning column 6 is rotatably mounted below the sliding frame 3. The positioning column 6 can rotate independently. The lower end of the positioning column 6 is fixedly connected to the connecting frame 7. The two ends of the connecting frame 7 are axially symmetrically mounted with two spray bars 10. The ends of the two spray bars 10 are respectively equipped with a rotating nozzle 11 and a cylindrical nozzle 12. The high-pressure hose 13 runs through the connection, connecting the rotating nozzle 11 and the cylindrical nozzle 12 to the external high-pressure cleaning water supply equipment to continuously deliver high-pressure cleaning water. The bottom of the frame 1 is fixedly equipped with a guardrail 9. After the ton container is transferred to the work position, the guardrail 9 completes the limiting and centering, preventing the ton container from shifting and shaking due to the impact of the high-pressure water flow during the cleaning process, and ensuring the stable operation of the cleaning work.

[0030] See Figure 2 , Figure 3 and Figure 8 As shown, a swing assembly 8 is provided on the positioning column 6. The swing assembly 8 includes a movable rod 81. The top of the movable rod 81 is locked and fixed to the pipe clamp 5. The rod moves downward and passes through the positioning column 6 and the connecting frame 7 below. Gears 82 are fixedly installed on the inner ends of the two spray rods 10 that are close to each other. The gears 82 are rotated and assembled inside the connecting frame 7. The bottom end of the movable rod 81 is fixed with a rack 83. The rack 83 and the gears 82 on both sides mesh synchronously and drive the transmission. The movable rod 81 is driven to move up and down linearly by the linear module assembly 4, which can drive the rack 83 to rise and fall synchronously. Through the meshing of the gears 82, the spray rods 10 on both sides are driven to flip inward and outward synchronously, changing the tilt angle of the spray rods 10 in real time, realizing the dynamic adjustment of the cleaning spray range. Unlike the traditional fixed tilt angle spray rods 10, which can only form a single ring-shaped rinsing band, it can cover the square barrel wall, rounded corners, and bottom transition area of ​​the ton barrel in all directions, greatly reducing the blind spots of the inner wall cleaning and improving the dirt removal effect.

[0031] See Figures 9-11 As shown, the end cap 14 is detachably mounted on the outside of the positioning post 6 by bolts. The positioning post 6 extends through the center of the end cap 14. The end cap 14 has symmetrical through slots 141 on the left and right sides. The high-pressure hose 13 passes through the through slots 141. The through slots 141 can limit and guide the high-pressure hose 13, preventing the high-pressure hose 13 from twisting and tangling during the rotation of the positioning post 6, avoiding twisting and blockage of the high-pressure pipeline, leakage of the sealing joint, and extending the service life of the high-pressure hose 13.

[0032] Several slots 142 are evenly opened along the circumference on the end face of the end cap 14. Each slot 142 is equipped with a radially retractable telescopic plate 15. The lower end face of the telescopic plate 15 can be tightly sealed against the end face of the ton barrel opening. Adjacent telescopic plates 15 are completely connected by an elastic membrane 16. The elastic membrane 16 can be radially stretched and contracted synchronously with the telescopic plate 15, completely sealing the splicing gap generated during the telescopic plate 15's extension and contraction. High-pressure water mist and splashed sewage inside the barrel cannot overflow upwards from the plate seam. This can prevent water vapor from corroding the upper guide rail 2, linear module, motor and other transmission electrical components, and also prevent cleaning sewage from spreading and polluting the on-site working environment.

[0033] See Figures 10-12 As shown, a sliding groove 143 is provided on the inner side of the end cap 14 corresponding to each slot 142. The number of sliding grooves 143 matches the number of telescopic plates 15. A sliding rod 17 is slidably mounted inside the sliding groove 143. The outer end of the sliding rod 17 is fixedly connected to the telescopic plate 15. The sliding rod 17 can drive the telescopic plate 15 to extend or retract radially synchronously by sliding horizontally along the sliding groove 143. A rotating ring 18 is rotatably mounted on the inner side of the end cap 14, at the outer ring position of the through groove 141. Multiple arc grooves 181 are provided along the circumference of the rotating ring 18. A limiting rod 19 is fixed at one end near the rotating ring 18. The limiting rod 19 is slidably locked inside the arc groove 181. When the rotating ring 18 is rotated, the inner wall of the arc groove 181 presses the limiting rod 19 to move horizontally in sync, which drives all the sliding rods 17 and telescopic plates 15 to expand outward or retract inward in sync. This achieves stepless adjustment of the overall sealing diameter of the end cover 14, which can be adapted to the mouths of various ton containers of different diameters on the market. It can complete the mixed-line cleaning operation of ton containers of various specifications without replacing the entire set of sealing accessories, and the equipment versatility is significantly improved.

[0034] Each telescopic plate 15 has a groove 151 on its outer ring. A sinking plate 20 is installed inside the groove 151. The inner arc surface of the sinking plate 20 can fit tightly against the outer wall of the barrel opening. A horizontal groove 152 is opened through the groove 151 of the telescopic plate 15. A movable plate 21 is vertically slidably installed inside the groove 152. The movable plate 21 is fixedly connected to the sinking plate 20. The sinking plate 20 and the telescopic plate 15 form a double-layer sealing structure. The lower end of the telescopic plate 15 presses against the upper end of the barrel opening, and the sinking plate 20 wraps around the outer wall of the barrel opening. The double sealing structure greatly improves the sealing effect of the barrel opening and effectively prevents high-pressure water mist from leaking out from the edge gaps of the barrel opening. At the same time, the sinking plate 20 can adapt to slight roundness and size errors of the barrel opening and flexibly fits the barrel opening, eliminating the problem of leakage due to partial sealing failure.

[0035] See Figures 10-12As shown, a receiving groove 153 is provided at the position where the telescopic plate 15 fits against the inner surface of the end cover 14. A limiting plate 22 is installed inside the receiving groove 153. One end of the limiting plate 22 is fixed to the inner wall of the end cover 14, and the other end extends into the receiving groove 153. An inclined groove 221 is provided on the surface of the limiting plate 22. A vertical rod 23 is fixed to the side of the moving plate 21. The end of the vertical rod 23 is slidably embedded in the surface of the inclined groove 221 and the surface of the limiting plate 22. When the sliding rod 17 drives the telescopic plate 15 to expand radially outward, the vertical rod 23 slides relative to the inclined surface of the inclined groove 221, and simultaneously pushes the moving plate 21 to move downward, causing the sinking plate 20 to fall synchronously to fit against the outer wall of the barrel opening. When the telescopic plate 15 shrinks inward, the vertical rod 23 slides in the opposite direction along the inclined groove 221, pulling the sinking plate 20 upward to retract. After the entire plate is folded inward, the outer diameter is smaller than the inner diameter of the minimum barrel opening. During the lifting and lowering process, there will be no scraping or bumping of the barrel opening flange and threads, and the equipment lifts and lowers smoothly without jamming.

[0036] See Figure 9 and Figures 13-14 As shown, a movable groove 144 communicating with a sliding groove 143 is formed on the upper surface of the end cap 14. A movable block 24 is slidably assembled inside the movable groove 144. The lower end of the movable block 24 is fixedly connected to the top of the slide rod 17. The operator can visually observe the extension and retraction stroke of the slide rod 17 by the movement distance of the movable block 24, and adjust the movement distance of the telescopic plate 15 to adapt to ton containers with different openings. A vertical plate 25 is fixed to the upper surface of the end cap 14 and the side of the movable groove 144. Multiple rotating rods 26 are rotatably mounted horizontally on the vertical plate 25. A label 30 is installed on the outer end of the rotating rod 26. Different labels 30 can be used to indicate the corresponding ton container diameter, allowing staff to quickly identify the current adjustment position of the telescopic plate 15 and reduce the time required for changeover and debugging. A swing rod 27 is fixed to the other end of the rotating rod 26. A torsion spring 28 is installed between the swing rod 27 and the vertical plate 25. Under normal conditions, the torsion spring 28 pulls the swing rod 27 to maintain its tilt. A push rod 29 is fixed to the side of the moving block 24. The push rod 29 moves radially synchronously with the moving block 24 and movably abuts against the swing rod 27. When the telescopic plate 15 expands outward and the moving block 24 slides outward, the push rod 29 pushes the swing rod 27 to rotate, causing the rotating rod 26 and the label 30 to be lifted and displayed synchronously. After the telescopic plate 15 retracts inward and the moving block 24 returns to its original position, the torsion spring 28 pulls the swing rod 27 to rotate, and the label 30 retracts synchronously. The automatic pop-up and retraction of the caliber label is achieved through mechanical linkage, without the need for additional sensing or electrical control components, making the structure simple and reliable.

[0037] See Figures 4-7As shown, in the initial standby state, the spray bar 10 is not inserted into the ton container. The spray bars 10 on both sides are arranged vertically, and the rotating nozzle 11 and the cylindrical nozzle 12 are vertically downward. At this time, the spray bars 10 on both sides are narrow and the overall outer diameter is smaller than the inner diameter of the ton container opening. When the lifting mechanism drives the entire set of spray bars 10 to move downward, the spray bars 10, nozzles and spray heads can pass smoothly through the ton container opening without any risk of scraping or jamming, which facilitates the mechanism to smoothly enter the inner cavity of the ton container to carry out cleaning operations.

[0038] As the sliding frame 3 descends along the guide rail 2, it drives the spray bar 10 to fully extend into the ton container. After the end cap 14 falls to the position of the ton container opening, the rotating ring 18 drives all the telescopic plates 15 to expand outward synchronously. The lower end of the telescopic plate 15 presses against the end face of the container opening to complete the seal. The external high-pressure cleaning equipment is started, and the high-pressure water flow is delivered to the rotating nozzle 11 and the cylindrical nozzle 12 through the high-pressure hose 13. The water flow is sprayed vertically downward, concentrating on impacting the inner wall of the bottom of the ton container. It performs targeted high-pressure flushing on the thick residue deposited at the bottom of the container and the dead corners of the drain outlet. The vertical jet can form a strong water wedge effect, quickly peeling off dried and viscous materials and efficiently removing stubborn dirt from the bottom of the container.

[0039] After the bottom cleaning is completed, the drive unit above the frame 1 slowly lifts the positioning column 6 upwards. During the lifting process, the positioning column 6 rotates synchronously, and the rotating nozzle 11 and the cylindrical nozzle 12 rise synchronously with the positioning column 6. The 360° revolution composite motion continuously changes the height and circumferential position of the sprayed water flow. Simultaneously, the linear module assembly 4 drives the pipe clamp 5 to move the movable rod 81 downward. The rack 83 at the bottom of the movable rod 81 moves downward in sync, and the rack 83 meshes with the gears 82 on both sides to rotate synchronously, driving the two originally vertical spray rods 10 to flip to both sides in sync, switching from a vertical state to an approximately horizontal unfolded state. The rotating nozzles 11 and cylindrical nozzles 12 on both sides expand outward significantly, and the spray coverage radius increases significantly. The high-pressure water flow can fully cover the inner walls of the four sides of the ton barrel and the rounded transition areas at the four corners. The dynamically changing spray angle can continuously adjust the water inflow angle for different curved surfaces of the barrel wall. It can vertically impact and peel off large scale layers, and can also rely on the lateral shearing force generated by the oblique water flow to sweep away thin layers of residue. It completely eliminates the cleaning blind spots that exist in the traditional fixed-angle spray rods 10. The cleaning uniformity of the inner wall of the ton barrel is greatly improved. There is no need for multiple reciprocating rinsing cycles, which effectively saves high-pressure water consumption and equipment energy consumption, and shortens the single cleaning cycle.

[0040] When the sliding frame 3 raises the spray bar 10 to the preset height, the lifting action temporarily stops, and the cleaning operation of the upper part of the barrel is completed. Then, the linear module assembly 4 drives the movable rod 81 to return to the initial height in the reverse direction, the rack 83 moves upward synchronously, and the meshing gear 82 rotates in the reverse direction, driving the spray bars 10 on both sides to retract from the horizontal unfolded state back to the vertical state. The nozzles and spray heads retract downwards again, and the outer diameter of the entire spray bar 10 assembly shrinks to a size smaller than the barrel opening. After completing all the inner wall cleaning processes, the sliding frame 3 is raised upward along the guide rail 2, and the retracted spray bar 10 can be smoothly pulled out from the barrel opening without scratching the barrel opening structure. Then, the cleaned barrel is moved out from the guardrail 9 and can be placed into the barrel to be cleaned to enter the next cleaning cycle. The entire operation process is automated and continuous, without the need for manual entry into the barrel for cleaning, avoiding safety hazards such as poisoning in confined spaces and high-pressure water impact.

[0041] The entire mechanism integrates a dynamically adjustable spray bar 10, a multi-diameter adaptive sealing end cap 14, and a mechanical linkage diameter marking component. All movements are achieved through the mechanical linkage of the original lifting, linear module, and rotating positioning column 6, eliminating the need for a large number of independent drive components. It has a compact structure, is easy to disassemble and maintain, and can be adapted to automated high-pressure cleaning of various specifications of ton containers in industries such as food, coatings, and fine chemicals. It has a wide cleaning coverage, excellent descaling effect, and strong equipment versatility. At the same time, it has good sealing and anti-splash capabilities, reducing on-site pollution and equipment wear.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
