Description

Technical Field

[0001] This application relates to the field of equipment cleaning technology, and in particular to a pressure vessel external wall cleaning mechanism. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Due to their ease of use and high safety, pressure vessels are widely used in the chemical and petrochemical industries, primarily for storing and transporting pressurized gases or liquefied gases. During the manufacturing, installation, operation, and maintenance of pressure vessels, various impurities, such as oil, dust, metal particles, and oxides, may adhere to their outer surface. Therefore, regular cleaning of the outer surface is an important measure to ensure the normal operation of the equipment.

[0003] A vertical pressure vessel cleaning device is disclosed in the patent with publication number CN222175296U. When using it, the staff first needs to raise the pressure vessel until it is higher than the height of the positioning sleeve before the pressure vessel can be placed on the water guide seat, which is quite inconvenient. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a pressure vessel external wall cleaning mechanism.

[0005] This application can be achieved through the following technical solution: a pressure vessel outer wall cleaning mechanism, including a placement platform for placing workpieces, an annular groove formed on the placement platform, the annular groove being able to surround the workpiece, the annular groove being slidably connected to several sliding frames, the sliding frames being able to slide along the length direction of the annular groove so that the interval between two adjacent sliding frames is sufficient for a workpiece to pass through, the sliding frames being provided with nozzles, the nozzles being able to deliver cleaning fluid to the workpieces, and a slope being installed on the placement platform, the end of the slope closer to the placement platform being higher than the end of the slope farther from the placement platform, the top of the slope being flush with the top of the placement platform.

[0006] In the above technical solution, by setting up a slope, the worker can push the workpiece onto the placement platform. By setting up a sliding frame that can slide along the annular groove, the worker can move the sliding frame so that the nozzle sprays water onto different parts of the workpiece.

[0007] Furthermore, it also includes a driving device, on which a brush frame is installed. The brush frame is provided with several brush blocks that can contact the outer wall of the workpiece. The driving device is used to drive the brush frame to slide vertically so that the brush blocks can contact the outer wall of the workpiece.

[0008] In the above technical solution, the driving device can be installed on the workshop ceiling. The driving device can drive the brush cleaning frame to rise and fall so that the brush cleaning block can contact the outer wall of the workpiece and thus brush the outer wall of the workpiece.

[0009] Furthermore, the scrubbing block includes a mounting block and a sponge disposed on the mounting block. The mounting block is provided with a sliding block, and an annular block is formed on the inner wall of the scrubbing frame. The annular block can surround the workpiece. A sliding groove is coaxially formed on the inner wall of the annular block. The sliding block is slidably connected to the sliding groove. A limiting end for limiting the sliding block is provided on the inner wall of the sliding groove. A groove is formed on the limiting end. The groove is used for a sliding block to be embedded so that the sliding block can be directly opposite the cross section of the sliding groove.

[0010] In the above technical solution, when it is necessary to fix the scrubbing block on the scrubbing frame, firstly, the sliding block on one scrubbing block is embedded in the groove. At this time, the sliding block is directly opposite the cross section of the groove. Then, the sliding block is pushed along the length of the groove, and the sliding block can slide along the length of the groove. In this way, several scrubbing blocks can be fixed on the scrubbing frame.

[0011] Furthermore, the sliding block is provided with several insert rods, and the brush holder is provided with several insertion holes for inserting the insert rods. A slider is slidably connected to the insert rod, and a spring is provided inside the insert rod to force the slider to protrude from the insert rod. The sliding block and the slider can respectively abut against the bottom surface of the groove and the outer wall of the brush holder so that the sliding block is kept embedded in the groove.

[0012] In the above technical solution, the insert rod can be inserted into the insertion hole so that the sliding block and the slider abut against the bottom surface of the trough and the outer wall of the brush rack respectively. At this time, the sliding block is embedded in the groove so that the position of the sliding block in the groove relative to the brush rack is fixed.

[0013] Furthermore, the slider has a bevel formed on it, which can contact the insertion hole to retract the slider into the insertion rod.

[0014] In the above technical solution, when the inclined surface contacts the insertion hole, the slider can retract into the insertion rod, which improves the convenience for workers to install the scrubbing block.

[0015] Furthermore, the sliding frame includes a sliding block and a sliding rod slidably connected to the sliding block. The sliding rod can slide along the height direction of the sliding block, and the nozzle is fixed on the sliding rod.

[0016] In the above technical solution, the sliding rod can slide along the height direction of the sliding frame so that the height of the nozzle is adjustable, so that the nozzle can spray cleaning fluid onto parts of the workpiece at different heights.

[0017] Furthermore, steps are formed on both inner walls of the annular groove, and a filter screen is placed on the steps. The sliding frame can slide against the upper surface of the filter screen.

[0018] In the above technical solution, the steps facilitate the installation of filter screens, which can filter impurities on the outer wall of the workpiece as well as impurities and garbage in the workshop.

[0019] Furthermore, the cross-section of the sliding rod is circular.

[0020] In the above technical solution, the cross-section of the sliding rod is circular so that the sliding rod can rotate to a certain extent, so that the nozzle can rotate with the sliding rod, thereby making the spraying range of the nozzle wider.

[0021] Furthermore, the slope is provided with rollers that can contact the workpiece.

[0022] In the above technical solution, the rollers make it easier for workers to push the workpieces onto the placement platform.

[0023] In summary, this application has the following technical advantages: By setting up a slope, workers can push the workpiece onto the placement platform; by setting up a sliding frame that can slide along the annular groove, workers can move the sliding frame to allow the spray nozzles to spray water onto different parts of the workpiece. The drive equipment can be installed on the workshop ceiling, and the drive equipment can drive the brush frame to rise and fall so that the brush blocks can contact the outer wall of the workpiece to brush the outer wall of the workpiece.

[0034] Reference Figure 1 and Figure 2 One embodiment of this application provides a pressure vessel outer wall cleaning mechanism, including a placement platform 1, on which a workpiece, namely a pressure vessel, is placed. An annular groove 11 with an upper opening is formed on the placement platform 1, and the axis of the annular groove 11 coincides with the axis of the placement platform 1. When the workpiece is placed on the placement platform 1, the annular groove 11 can surround the workpiece. Steps 16 are formed on the two opposite inner walls of the annular groove 11, and several filter screens 15 are placed on the steps 16. The several filter screens 15 are arranged along the length direction of the annular groove 11. The bottom of the annular groove 11 can be connected to the municipal drainage pipe through a drain pipe. Five sliding frames 2 are slidably connected to the annular groove 11. All five sliding frames 2 can slide along the length of the annular groove 11. Each sliding frame 2 includes a sliding block 21 slidably connected to the annular groove 11 and three sliding rods 22 slidably connected to the sliding block 21. The sliding block 21 can slide against the upper surface of the filter screen 15. The sliding rods 22 can slide along the height of the sliding block 21. A nozzle 3 is installed at the top of the sliding rod 22. The nozzle 3 can be connected to a water pump located in a water storage tank via a hose.

[0035] Please refer to Figure 1 To facilitate workers in moving workpieces onto the placement platform 1, a ramp 4 is installed on the side wall of the placement platform 1. The top of the ramp 4 is flush with the upper surface of the placement platform 1, and the end of the ramp 4 closer to the placement platform 1 is higher than the end of the ramp 4 further away from the placement platform 1. Several rollers 14 are installed on the ramp 4. When the workpiece is pushed upward along the ramp 4, it can drive the rollers 14 to rotate. This design makes it easier for workers to push the workpieces onto the placement platform 1. After the workpiece is placed on the placement platform 1, the sliding frame 2 is slid along the length of the annular groove 11 so that the interval between two adjacent sliding frames 2 is large enough for a workpiece to pass through. This allows the worker to push the workpiece onto the placement platform 1 via the ramp 4. Then, the sliding frame 2 can be moved so that the nozzle 3 can spray cleaning fluid onto different positions of the workpiece. The cleaning fluid can be water or other liquids that can clean the workpiece. When the sliding rod 22 is raised or lowered to a certain position, it can be fixed relative to the sliding block 21 due to friction. The cross-section of the sliding rod 22 is circular, which allows the sliding rod 22 to rotate relative to the sliding block 21.

[0036] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 A drive device 5 is installed above the platform 1. The drive device 5 can be an electric actuator or other actuator capable of telescopic movement. The drive device 5 can be installed on the ceiling of the workshop. A brushing frame 6 is installed on the telescopic end of the drive device 5. An annular block 61 is coaxially formed on the inner wall of the brushing frame 6. A sliding groove 81 is coaxially opened on the annular block 61. The opening of the sliding groove 81 faces the axis of the annular block 61. The brushing block 7 includes a mounting block 71 and a sponge 72 installed on the mounting block 71. The sponge 72 can contact the outer wall of the workpiece. A sliding block 711 is installed on the end of the mounting block 71 away from the sponge 72. The sliding block 711 is slidably connected to the sliding groove 81. Limiting ends 9 are formed on the two opposite inner walls of the sliding groove 81 to prevent the sliding block 711 from disengaging from the sliding groove 81. The drive device 5 can drive the brush rack 6 to move down so that several sponges 72 can contact the outer wall of the workpiece to clean it. In order to ensure that several sponges 72 can contact the workpiece when the brush rack 6 moves down, the operator can draw lines on the placement platform 1 in advance to ensure that the placement position of the workpiece is accurate.

[0037] Please refer to Figure 7 and Figure 8 A groove 91 is provided on the limiting end 9, which can accommodate a sliding block 711 on a scrubbing block 7. Two insert rods 10 are installed on the sliding block 711 of the scrubbing block 7. A slider 12 is slidably installed on the insert rod 10. A spring 13 is provided inside the insert rod 10 to force the slider 12 to protrude from the insert rod 10. The spring 13 is a compression spring. An inclined surface 121 is formed on the slider 12. Two insertion holes 83 are provided through the scrubbing frame 6. The two insertion holes 83 are inserted into the annular block 61 and located at the bottom of the groove 81. The two insertion holes 83 are used for the insertion of the two insert rods 10 respectively. When the inclined surface 121 contacts the insertion hole 83, the slider 12 can retract into the insert rod 10. When the inclined plane 121 is far away from the insertion hole 83, the slider 12 can protrude from the outer wall of the insertion rod 10 along its length. By setting the groove 91, the operator can place a scrubbing block 7 in the groove 91. At this time, the sliding block 711 of the scrubbing block 7 can be directly opposite the cross section of the groove 81. Then, the scrubbing block 7 is pushed along the length of the groove 81 and the scrubbing block 7 is fixed on the scrubbing frame 6. Multiple scrubbing blocks 7 are arranged in this way on the annular block 61. Then, the last scrubbing block 7 is embedded in the groove 91 and the two insertion rods 10 on the sliding block 711 are inserted into the two insertion holes 83 one by one until the sliding block 711 and the slider 12 can respectively abut against the bottom surface of the groove 81 and the outer wall of the scrubbing frame 6.

[0038] The working principle of this embodiment is as follows: First, the workpiece is pushed along the slope 4 onto the placement platform 1 and located directly below the brushing frame 6. Then, the nozzle 3 delivers cleaning liquid to the workpiece. Then, the driving device 5 drives the brushing frame 6 to move down so that the sponge 72 can brush the outer wall of the workpiece.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
