Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning device for the production and processing of LNG cryogenic cylinders. Background Art

[0002] A steel cylinder is a steel cylinder used to store gas, liquefied gas or mixed gas. It adopts a double-layer design structure. Its inner liner is used to store LNG, and multiple layers of insulation materials are wrapped around the outer wall of the inner liner, which has thermal insulation performance. At the same time, the interlayer of the steel cylinder (the space between the inner liner and the outer shell) is evacuated to a high vacuum, forming a high vacuum multi-layer insulation system, so that LNG can be stored at low temperatures. In the production and processing of LNG cryogenic steel cylinders, using a cleaning device to clean the unformed steel cylinder body is an important step in the production and processing. The cleaning device places the workpiece on the placement roller, and then pushes the workpiece to rotate on the placement roller. At this time, the cleaning mechanism is set above the workpiece and cleans the body of the workpiece, which helps to remove surface impurities, ensure welding quality, improve molding quality, and meet health and safety standards.

[0003] However, the existing cleaning device still has some defects during use: first, since the cleaning device only limits and fixes the workpiece by placing rollers, the stability of the workpiece setting is poor. When the workpiece rotates due to the thrust, the workpiece is easy to break away from the limit of the placing rollers, thereby affecting the cleaning efficiency and effect of the cleaning mechanism on the workpiece; secondly, the existing cleaning mechanism relies on the cleaning nozzle to spray the cleaning solution. Because the cleaning nozzles are on the same horizontal line, if the number of cleaning nozzles is too small, the outer wall of the workpiece cannot be fully cleaned. If the number of cleaning nozzles is too large, not only the use cost of the device is increased, but also water resources are wasted. Summary of the invention

[0018] An auxiliary mechanism is arranged below the cleaning mechanism and above the workpiece, and the auxiliary mechanism is composed of an auxiliary part and an auxiliary block. When the cleaning nozzle sprays the cleaning solution downward, the fine cleaning solution first passes through the auxiliary part and then moves to the workpiece. In this process, the setting of the auxiliary block effectively guides the cleaning solution to continuously disperse and converge, thereby making several water flows that do not contact each other form a layer of evenly distributed and interconnected water flows. Therefore, when the use cost is reduced and the number of cleaning nozzles is reduced, the cleaning effect and efficiency of the cleaning mechanism on the workpiece are effectively improved, and the outer wall of the workpiece is fully cleaned.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, a cleaning device for production and processing of LNG cryogenic cylinders, comprising: like Figure 1-Figure 2 The fixing mechanism 1 has a workpiece 9 disposed therein for providing a space for cleaning the workpiece 9. The fixing mechanism 1 includes a fixing housing 11, a fixing door 12 and a fixing column 13. Figure 1 The top view shape of the fixed shell 11 is a "concave" shape, one end of the fixed door 12 is movably hinged to one end of the fixed shell 11, and the other end of the fixed door 12 is movably engaged with the other end of the fixed shell 11. When working, the fixed door 12 and the fixed shell 11 form a top view shape of a "mouth" shape. At this time, the workpiece 9 can be cleaned in the fixed mechanism 1. When not working, the fixed door 12 is opened to facilitate the entry and exit of the workpiece 9. A drying mechanism is provided on the inner wall of the fixed shell 11 and the fixed door 12. After cleaning, the drying mechanism can spray compressed air to dry the workpiece 9 to avoid water droplets on the workpiece 9 and dust and impurities being contaminated during movement. The four corners of the bottom end of the fixed shell 11 are fixedly connected with fixed columns 13, which can support the fixed shell 11 and the fixed door 12 to ensure the stability of the fixed mechanism 1.

[0023] like Figure 1-Figure 4 , working mechanism, a group of working mechanisms are arranged on the left and right sides inside the fixing mechanism 1, and the two groups of working mechanisms are respectively located at the left and right ends of the workpiece 9, which are used to drive the workpiece 9 to rotate stably. The working mechanism includes a rotating component 4, a telescopic component 5 and a limiting component 6.

[0024] like Figure 5 , Figure 7 , Figure 10-Figure 14 , the limiting component 6, the limiting component 6 is movably connected to the workpiece 9, and the axis of the limiting component 6 is the same as the axis of the workpiece 9, which is used to enhance the rotation stability of the workpiece 9. The two limiting components 6 are symmetrically arranged. When the two limiting components 6 move toward each other, the two limiting components 6 will fit in the middle of the workpiece 9 to facilitate the stable fixation of the workpiece 9. When the two limiting components 6 move away from each other, the two limiting components 6 can be moved out of the workpiece 9 to facilitate the flexible transfer of the workpiece 9. The limiting component 6 includes a limiting plate 61, a limiting ring 62, a limiting capsule 63 and a limiting tube 64, such as Figure 12-13A limiting groove is provided on one side of the limiting plate 61, and the limiting groove is located on the side of the limiting plate 61 away from the other limiting plate 61. The side view shape of the limiting groove is circular, and the cross-sectional shape of the limiting groove is a "convex" shape, so that it can prepare for the telescopic component 5 and the movable component 8 to be movably connected to the limiting plate 61. The inner ring of the limiting ring 62 is fixedly sleeved with the outer wall of the limiting plate 61, and the outer ring of the limiting ring 62 is movably sleeved with the inner wall of the workpiece 9. The limiting ring 62 is fully fitted with the workpiece 9, so that the workpiece 9 can be moved by the limiting plate 61 and the limiting ring 62. The limiting ring 62 is driven to rotate synchronously, so that the limiting plate 61 and the limiting ring 62 limit the position of the workpiece 9, effectively enhancing the stability of the workpiece 9 during rotation, and preventing the workpiece 9 from moving during the self-rotation process and affecting the cleaning of the workpiece 9. The limiting ring 62 is made of elastic rubber material, and the interior of the limiting ring 62 is filled with inert gas. A circular groove is provided on the other side of the limiting plate 61, and the circular groove is located on the side of the limiting plate 61 close to the other limiting plate 61. One end of the limiting capsule 63 is fixedly connected to the circular groove of the limiting plate 61, and The other end of the limiting capsule 63 is movably connected to the circular groove of the limiting plate 61, providing conditions for the expansion and contraction deformation of the limiting capsule 63 in the circular groove. The limiting capsule 63 is made of elastic rubber material, and the interior of the limiting capsule 63 is filled with inert gas. The limiting tube 64 is movably connected to the limiting plate 61, and one end of the limiting tube 64 is fixedly connected to the interior of the limiting ring 62, and the other end of the limiting tube 64 is fixedly connected to the interior of the limiting capsule 63. When the two limiting components 6 are not in contact, the limiting capsule 63 stretches under the action of its own elasticity, that is, part of the limiting capsule 63 is located outside the limit plate 61. At this time, the limit ring 62 shrinks under the action of its own elasticity, that is, the limit ring 62 will not affect the movement of the limit component 6 in the workpiece 9. When the two limit components 6 are fitted together, the two limit bags 63 squeeze each other and are completely compressed into the circular groove of the limit plate 61. At this time, the inert gas in the limit bag 63 is transferred to the limit ring 62 through the limit tube 64, thereby pushing the limit ring 62 to expand, so that the limit ring 62 and the workpiece 9 are fully fitted, so as to realize the self-rotation of the limit component 6 and drive the workpiece 9 to rotate synchronously.

[0025] like Figure 5 , Figure 7 , Figure 10-Figure 14 , a rotating assembly 4, one end of which is fixedly connected to the fixing mechanism 1, and the other end of which is fixedly connected to the limiting assembly 6, for controlling the rotation of the limiting assembly 6, the rotating assembly 4 includes a rotating motor 41, a first rotating shaft 42, a second rotating shaft 43 and a third rotating shaft 44, as shown Fig.11The rotating motor 41 is fixedly arranged outside the fixed housing 11, and can provide power for the rotation of the first rotating shaft 42, the second rotating shaft 43, and the third rotating shaft 44. One end of the first rotating shaft 42 is movably connected to the rotating motor 41, and the first rotating shaft 42 passes through the wall of the fixed housing 11. The other end of the first rotating shaft 42 is provided with a long groove, and the first rotating shaft 42 is movably connected to one end of the second rotating shaft 43 through the long groove. The other end of the second rotating shaft 43 is provided with a long groove, and the second rotating shaft 43 is movably connected to one end of the third rotating shaft 44 through the long groove. The other end of the third rotating shaft 44 is fixedly connected to the middle part of the limiting plate 61. When the limiting assembly 6 is pushed to move horizontally, the first rotating shaft 4 2. The connection setting of the first rotating shaft 42 and the second rotating shaft 43 can change the length following the movement of the limit assembly 6, thereby improving the flexibility of the setting of the rotating assembly 4. When the rotating motor 41 controls the first rotating shaft 42, the second rotating shaft 43, and the third rotating shaft 44 to rotate, the first rotating shaft 42 and the connection setting of the first rotating shaft 42 and the second rotating shaft 43 can drive the limit plate 61 to rotate synchronously. The second rotating shaft 43 and the third rotating shaft 44 are shaped like rods with protrusions on the outer walls, which can ensure that the first rotating shaft 42, the second rotating shaft 43, and the third rotating shaft 44 can only be displaced in the horizontal direction, and no rotational displacement can occur between the three, thereby ensuring the synchronization of the three during the rotation process.

[0026] like Figure 5 , Figure 7 , Figure 10-Figure 14 , a telescopic component 5, one end of the telescopic component 5 is fixedly connected to the fixing mechanism 1, and the other end of the telescopic component 5 is movably connected to the limit component 6, which is used to push the limit component 6 to move horizontally. Two telescopic components 5 are arranged in one working mechanism, and the two telescopic components 5 are located at the front and rear sides of the rotating component 4, which effectively improves the stability of the telescopic component 5 controlling the horizontal movement of the limit component 6 and the stability of the rotating component 4 controlling the self-rotation of the limit component 6. The telescopic component 5 includes a telescopic cylinder 51, a telescopic rod 52 and a telescopic plate 53, as shown in FIG. Fig.11 The outer wall of the telescopic cylinder 51 is fixedly sleeved on the wall surface of the fixed shell 11, and can provide power for the horizontal movement of the telescopic rod 52 and the telescopic plate 53. One end of the telescopic rod 52 is movably connected to the telescopic cylinder 51, and the other end of the telescopic rod 52 is fixedly connected to the telescopic plate 53. The telescopic plate 53 is a circular plate, and the telescopic plate 53 is movably engaged in the limiting groove of the limiting plate 61. When the telescopic assembly 5 is working, the telescopic cylinder 51 can control the horizontal movement of the telescopic rod 52 and the telescopic plate 53, thereby driving the rotating assembly 4 and the limiting assembly 6 to move horizontally. When the rotating assembly 4 is working, the limiting assembly 6 rotates by itself. At this time, the telescopic plate 53 in a stationary state moves relative to the limiting groove of the limiting plate 61, effectively ensuring the stability of the limiting assembly 6 during the rotation process.

[0027] Embodiment 2, based on embodiment 1, a cleaning device for production and processing of LNG cryogenic cylinders, further comprising: like Figure 5-Figure 6 , a placing mechanism 2 is fixedly placed at the bottom of the fixing mechanism 1 for placing the workpiece 9, and the placing mechanism 2 includes a placing table 21, a placing roller 22 and a guide rod 23, as shown in FIG. Figure 6 The number of the placement tables 21 is two, and the two placement tables 21 are symmetrically arranged. The placement tables 21 can be arranged as a vertically retractable component, so that the size of the workpiece 9 that can be cleaned by the cleaning device can be expanded, and the universality of the cleaning device is improved. A placement roller 22 is movably connected between the two placement tables 21. The number of the placement rollers 22 is several, and several placement rollers 22 are arranged in a linear array. The workpiece 9 is placed on the placement rollers 22. When the working mechanism has not yet worked on the workpiece 9, the placement rollers 22 can be used to stably place the workpiece 9. One side of a placement table 21 is movably connected with several guide rods 23, and several guide rods 23 are arranged in a linear array. The guide rod 23 is located below the fixed shell 11 and the fixed door 12, and the guide rod 23 passes through the fixed door 12. When the fixed door 12 is opened, the staff can move the workpiece 9 along the guide rod 23, thereby realizing the transfer of the workpiece 9.

[0028] like Figure 5 , Figure 7-Figure 9 , a cleaning mechanism 3 is fixedly arranged on the upper part of the fixing mechanism 1, and is used to clean the workpiece 9. The cleaning mechanism 3 includes a cleaning member 31, a cleaning pipe 32 and a cleaning nozzle 33, such as Figure 8 The cleaning member 31 is in the shape of an inverted "concave" character, and the bottom end of the cleaning member 31 is fixedly connected to the top end of the fixed shell 11, and the cleaning member 31 is located in the middle of the fixed shell 11, that is, the cleaning member 31 is located in the middle of the upper part of the workpiece 9, thereby laying a foundation for the cleaning mechanism 3 to spray and clean the workpiece 9 accurately. A cleaning pipe 32 is fixedly sleeved in the middle of the top end of the cleaning member 31, and one end of the cleaning pipe 32 extending out of the cleaning member 31 is connected to the water supply pipe, one end of the cleaning nozzle 33 is fixedly connected to the inner bottom end of the cleaning pipe 32, and the other end of the cleaning nozzle 33 passes through the cleaning member 31. When the cleaning mechanism 3 is working, the water supply pipe provides a cleaning solution that can clean the workpiece 9 into the cleaning pipe 32, and then the cleaning solution in the cleaning pipe 32 is discharged downward through the cleaning nozzle 33 to clean the outer wall of the workpiece 9. There are a number of cleaning nozzles 33, and a number of cleaning nozzles 33 are arranged in a linear array to effectively clean the top of the outer wall of the workpiece 9, and it is necessary to ensure that the number of cleaning nozzles 33 is not too large, thereby avoiding cost waste.

[0029] like Figure 5-Figure 7 , Figure 14-17, Auxiliary mechanism 7, an auxiliary mechanism 7 is provided on the workpiece 9, and the auxiliary mechanism 7 is located directly below the cleaning mechanism 3, for enhancing the cleaning efficiency and effect of the workpiece 9, the auxiliary mechanism 7 includes an auxiliary member 71 and an auxiliary block 72, such as Fig.17 , both ends of the auxiliary member 71 are fixedly connected to the inner wall of the fixed shell 11, and the auxiliary member 71 is located between the workpiece 9 and the cleaning mechanism 3. When the cleaning mechanism 3 sprays the cleaning solution downward, the water flow formed by the cleaning solution needs to pass through the auxiliary member 71 before it can move toward the workpiece 9, effectively providing conditions for uniform water flow. A transverse hole is opened in the middle of the auxiliary member 71, and the auxiliary member 71 is fixedly connected to the auxiliary block 72 through the transverse hole. The auxiliary block 72 has two groups, upper and lower, and each group of auxiliary blocks 72 consists of two rows of symmetrically arranged auxiliary blocks 72. The lower auxiliary block 72 is arranged between the upper two auxiliary blocks 72, and the shape of the auxiliary block 72 The shape is composed of a semi-cone and a semi-cylinder. When the water flows through the transverse hole of the auxiliary part 71, the water flow is first dispersed under the action of the semi-cone of the auxiliary block 72, and then the multiple dispersed water flows are vertically moved under the action of the semi-cylinder of the auxiliary block 72. Due to the position setting of the upper and lower groups of auxiliary blocks 72, the water flow can be diverted and merged twice, and then several water flows that do not contact each other form a layer of evenly distributed and interconnected water flow. Therefore, when the use cost is reduced and the number of cleaning nozzles 33 is set small, the setting of the auxiliary mechanism 7 effectively improves the cleaning effect and efficiency of the cleaning mechanism 3 on the workpiece 9, so that the outer wall of the workpiece 9 is fully cleaned.

[0030] Embodiment 3, based on embodiment 2, the auxiliary mechanism 7 further includes: like Figure 5-Figure 7 , Figure 14-18 , movable components 8, two movable components 8 are movably arranged at both ends of the interior of the auxiliary member 71 for further cleaning the workpiece 9, and the movable components 8 include a movable pipe 81, a movable plate 82, a movable member 83, a movable rope 84, a water inlet pipe 85 and a water outlet 86, such as Fig.18The movable tube 81 is movably sleeved on the auxiliary member 71, and the movable tube 81 is made of a bendable rubber material, which effectively enables the movable tube 81 to change its shape along the auxiliary member 71 to adapt to work requirements. The outer wall of the movable tube 81 is fixedly provided with cleaning hairs. During the movement of the movable tube 81, the cleaning hairs on the outer wall of the movable tube 81 effectively clean the auxiliary block 72, thereby realizing the self-cleaning of the auxiliary mechanism 7, which not only improves the service life of the auxiliary mechanism 7, but also improves the cleanliness of the cleaning solution sprayed onto the workpiece 9. One end of the movable tube 81 is fixedly connected with a movable plate 82, and the shape of the movable plate 82 is a "king" shape, and the movable plate 82 is movably clamped in the horizontal hole of the auxiliary member 71, using the auxiliary member 7 1 and two sets of auxiliary blocks 72 realize the movable clamping of the movable plate 82, thereby ensuring the stability of the movable plate 82 during the horizontal movement. The two movable plates 82 have different magnetism, so that the movable tube 81 can move back into the auxiliary member 71 under the magnetic attraction of the two movable plates 82. The other end of the movable tube 81 passes through the bottom end of the auxiliary member 71 and is fixedly connected to the movable member 83. The movable member 83 is composed of two circular plates of different sizes, and the movable member 83 is movably clamped in the limiting groove of the limiting plate 61. When the telescopic component 5 is working, the telescopic component 5 drives the rotating component 4 and the limiting component 6 to move horizontally, thereby being able to pull the movable tube 81 and the movable member 83 to move, so that one end of the movable tube 81 is horizontal. The movable assembly 8 moves to the inside of the workpiece 9, thereby preparing for the movable assembly 8 to clean the inner wall of the workpiece 9. When the rotating assembly 4 is working, the rotating assembly 4 drives the limiting assembly 6 to rotate, so that the movable tube 81 and the movable part 83 in a stationary state move relative to the limiting groove of the limiting plate 61, that is, the movable tube 81 is always in a horizontal state, so that the movable assembly 8 can accurately clean the inner wall of the workpiece 9. The movable part 83 is internally fixedly sleeved with a movable rope 84, and one end of the movable rope 84 is fixedly connected to the movable plate 82, and the other end of the movable rope 84 is fixedly connected to the movable part 83. The movable rope 84 is made of a corrosion-resistant, wear-resistant material, and its length is not easily changed, so that the length of the movable tube 81 can be limited, and further The end of the movable tube 81 extending out of the auxiliary part 71 is in a horizontal state, and the state of the movable tube 81 will not be changed by the rotation of the limit assembly 6. One end of the water inlet pipe 85 passes through the cleaning part 31 and is fixedly connected to the cleaning tube 32. The other end of the water inlet pipe 85 is fixedly connected to the movable tube 81. The top of the movable tube 81 located inside the workpiece 9 is fixedly sleeved with a water outlet nozzle 86. There are several water outlet nozzles 86, and the several water outlet nozzles 86 are arranged in a linear array. When the cleaning mechanism 3 is working, the cleaning tube 32 can discharge the cleaning solution into the movable tube 81 through the water inlet pipe 85, and then flush the inner wall of the workpiece 9 through the water outlet nozzle 86, thereby effectively expanding the cleaning range of the workpiece 9 and making the workpiece 9 clean more fully.

[0031] The working principle of the method of the present invention is as follows: When the workpiece 9 needs to be cleaned, the fixed door 12 is first opened so that the workpiece 9 is pushed into the placement roller 22 along the guide rod 23, that is, the workpiece 9 is stably placed on the placement mechanism 2, and then the telescopic assembly 5 is started so that the telescopic cylinder 51 pushes the telescopic rod 52 to move, thereby driving the two limit assemblies 6 to move toward each other until the two limit assemblies 6 stop moving after being fitted to each other. During this process, the telescopic assembly 5 is synchronously stretched, that is, the first rotating shaft 42, the second rotating shaft 43 and the third rotating shaft 44 are stretched. In addition, when the two limit plates 61 are fitted to each other, the two limit capsules 63 will squeeze each other, so that the limit ring 62 will expand and fit the workpiece The inner wall of 9 is fully fitted, so that the limit assembly 6 is set concentrically and coaxially with the workpiece 9, effectively supporting and limiting the workpiece 9, thereby improving the stability of the workpiece 9 setting, and then starting the rotating assembly 4, so that the rotating motor 41 drives the first rotating shaft 42, the second rotating shaft 43 and the third rotating shaft 44 to rotate, thereby driving the limit assembly 6 to rotate, and then the workpiece 9 rotates synchronously. At this time, since the workpiece 9 is stably fixed by the limit assembly 6, the workpiece 9 will not produce any displacement other than rotation during the rotation process, which effectively ensures that the workpiece 9 is always aligned with the cleaning mechanism 3, and effectively improves the cleaning effect and efficiency of the cleaning mechanism 3 on the workpiece 9.

[0032] When the cleaning mechanism 3 cleans the workpiece 9, the cleaning solution in the cleaning pipe 32 is sprayed downward from the cleaning nozzle 33. The cleaning solution first enters the transverse groove of the auxiliary component 71, and under the action of the two groups of auxiliary blocks 72, several water flows are continuously dispersed and mixed, so that several water flows that do not contact each other form a layer of evenly distributed and interconnected water flow, and then the even water flow is sprayed vertically downward to effectively clean the outer wall of the workpiece 9 in the rotating process. Therefore, when the use cost is reduced and the number of cleaning nozzles 33 is set small, the setting of the auxiliary mechanism 7 effectively improves the cleaning effect and efficiency of the cleaning mechanism 3 on the workpiece 9, so that the outer wall of the workpiece 9 is fully cleaned. At the same time, due to the horizontal movement of the limit component 6, the movable pipe 81 is pulled to move, so that part of the movable pipe 81 is located inside the workpiece 9. At this time, the cleaning mechanism 3 works and the cleaning solution in the cleaning pipe 32 is discharged from the water inlet pipe 85 to the movable pipe 81, and finally discharged from the water outlet nozzle 86 to the inner wall of the workpiece 9, effectively expanding the cleaning range of the workpiece 9 and making the workpiece 9 clean more fully.

[0033] After the workpiece 9 is cleaned, the rotating component 4 and the limiting component 6 are disengaged from the workpiece 9 driven by the telescopic component 5. At this time, the movable tube 81 is not horizontally pulled by the limiting component 6, and moves back into the auxiliary part 71 under the action of the magnetic attraction of the two movable plates 82. During the movement of the movable tube 81, the cleaning hairs on the movable tube 81 and its outer wall effectively clean the auxiliary block 72, thereby realizing the self-cleaning of the auxiliary mechanism 7, which not only improves the service life of the auxiliary mechanism 7, but also improves the cleanliness of the cleaning solution sprayed on the workpiece 9. Finally, the cleaned and dried workpiece 9 is moved out of the fixing mechanism 1 through the guide rod 23.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
