Description

Technical Field

[0001] The invention relates to the technical field of degreasing cleaning equipment, in particular to a degreasing cleaning equipment for the inner surface of stainless steel of a high-pressure storage tank. Background Art

[0002] Degreasing cleaning is a common surface treatment method that aims to remove impurities such as grease and dirt from the surface of an object. Degreasing cleaning is commonly used in manufacturing, mechanical processing, automobile repair and maintenance, and other fields. The main principle of degreasing cleaning is to use chemical reactions or physical effects to remove grease and dirt from the surface of an object. Common degreasing cleaning methods include solvent cleaning, alkaline cleaning, acid cleaning, ultrasonic cleaning, etc.

[0003] The existing degreasing cleaning methods used for high-pressure storage tanks mostly use solvent cleaning. Solvent cleaning is a common degreasing cleaning method, which usually uses organic solvents such as alcohol, kerosene, acetone, etc. to remove grease and dirt on the surface of the object by soaking or spraying. The benefit of degreasing cleaning is that it can improve the cleanliness and adhesion of the surface of the object, which is conducive to the subsequent painting, spraying and processing processes.

[0004] However, since most high-pressure storage tanks are large in size, after the solvent is sprayed inside the tank, after a period of soaking, the grease and dirt on the inner wall float up. Since most of the dirt is insoluble in water, during the cleaning process, if auxiliary cleaning equipment is not used, the dirt that is tightly adhered to the wall surface is not easy to fall off. The time spent on degreasing and cleaning the high-pressure storage tank is long, and the cleaning efficiency is reduced. Therefore, the present application provides a high-pressure storage tank stainless steel inner surface degreasing and cleaning equipment to meet the needs. Summary of the invention

DETAILED DESCRIPTION

[0030] 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.

[0031] Embodiment 1:

[0032] refer to Figure 1 , Figure 2 The shown device is a degreasing and cleaning device for the inner surface of stainless steel of a high-pressure storage tank, comprising a plurality of probe frames 1 that can synchronously rise and fall, a plurality of nozzles 8 for spraying cleaning agent toward the interior of the high-pressure storage tank are arranged above the probe frames 1, during the cleaning operation, the cleaning agent sprayed into the interior of the high-pressure storage tank can make the dirt on the inner wall of the tank float up and separate from the wall, the probe frames 1 are equidistantly distributed along the circular trajectory of the inner surface of the high-pressure storage tank, and a rotatable adjustment sleeve 2 is provided on the probe frames 1, and the adjustment sleeve 2 is distributed in an elliptical structure.

[0033] It also includes a group of transverse cleaning scrapers 3 and vertical cleaning scrapers 4 arranged on the adjustment sleeve 2. The transverse cleaning scrapers 3 and the vertical cleaning scrapers 4 are relatively distributed along the short radius direction of the adjustment sleeve 2. As the multiple probe frames 1 rotate, the transverse cleaning scrapers 3 or the vertical cleaning scrapers 4 can clean the inner wall of the high-pressure storage tank and can quickly peel off impurities on the inner wall of the high-pressure storage tank to accelerate the separation of dirt so as to centrally process the cleaned dirt.

[0034] The distribution directions of the horizontal cleaning scraper 3 and the vertical cleaning scraper 4 are perpendicular to each other. Therefore, when the horizontal cleaning scraper 3 and the vertical cleaning scraper 4 successively perform cleaning operations on the inner wall of the high-pressure storage tank, the inner wall of the high-pressure storage tank can be cleaned from different directions, which can make the dirt that is tightly adhered to the inner wall of the tank fall off, thereby improving the comprehensiveness and cleaning quality of the cleaning operation.

[0035] The adjusting sleeve 2, the transverse cleaning scraper 3 and the vertical cleaning scraper 4 can move synchronously toward the central axis direction of the high-pressure storage tank, and adjust the distance between the transverse cleaning scraper 3 or the vertical cleaning scraper 4 and the inner wall of the high-pressure storage tank, so as to control the movement of the transverse cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 inside the high-pressure storage tank, effectively avoid the occurrence of friction with the inner wall of the high-pressure storage tank, and improve the stability and movement efficiency of the transverse cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 during the movement in the high-pressure storage tank.

[0036] According to the cleaning requirements, when the cleaning work of one of the two groups of horizontal cleaning scrapers 3 and vertical cleaning scrapers 4 is completed, the adjustment sleeve 2 can be controlled to rotate so that the two groups of horizontal cleaning scrapers 3 and vertical cleaning scrapers 4 switch positions. After the horizontal cleaning scrapers 3 and vertical cleaning scrapers 4 are switched, the cleaning operation in the other direction can be performed without manual replacement of cleaning tools, thereby improving the efficiency of the cleaning operation.

[0037] like Figure 3 , Figure 4 As shown, the probe frame 1 is provided with two support bars 11 distributed from top to bottom, and a positioning column 12 is provided at one end of the support bar 11 away from the probe frame 1. A connecting ring 21 coaxially distributed therewith is provided in the adjusting sleeve 2, and an adjusting shaft 22 is provided at the center of the connecting ring 21. The connecting ring 21 is located in the relative space between the two support bars 11, and a channel for accommodating the movement of the adjusting shaft 22 is provided on the support bar 11. The part of the adjusting shaft 22 exposed outside the two support bars 11 is connected to the positioning column 12 through a pressure spring 26.

[0038] The distance between the adjustment shaft 22 and the positioning column 12 is adjustable, so the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the adjustment sleeve 2 connecting the two can move synchronously with the adjustment shaft 22 to adjust the distance between the scraper and the inner wall of the high-pressure storage tank, so as to facilitate the control of the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 to move inside the high-pressure storage tank.

[0039] like Figure 5 , Figure 6 As shown, when the cleaning work of one of the two groups of horizontal cleaning scrapers 3 and vertical cleaning scrapers 4 is completed, it is necessary to control the horizontal cleaning scrapers 3, vertical cleaning scrapers 4 and the probe frame 1 to rise and move out of the high-pressure storage tank, switch the positions of the horizontal cleaning scrapers 3 and vertical cleaning scrapers 4, and implement the cleaning operation in the other direction. The part of the adjustment shaft 22 exposed outside the two support bars 11 is provided with a follower seat 23, and one side of the follower seat 23 distributed on the upper side is provided with a guide rack 24, and the side of the guide rack 24 away from the follower seat 23 is provided with a guide gear 13 meshing with it.

[0040] Before controlling the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 to move out of the high-pressure storage tank, as the guide gear 13 rotates, the guide rack 24, the follower seat 23, the adjustment shaft 22 and the connecting ring 21 engaged therewith can move toward the positioning column 12, thereby forming a gap between the scraper and the inner wall of the high-pressure storage tank. During the movement of the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1, the scraper can effectively avoid rubbing against the inner wall of the high-pressure storage tank, thereby improving the stability of the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 during the process of moving out of the high-pressure storage tank.

[0041] like Figure 7 , Figure 8 As shown, the adjusting shaft 22 is provided with an adjusting gear 25 which can rotate synchronously therewith, and the first driving motor 15 is provided on both sides of the supporting bar 11. The main shaft of the first driving motor 15 on one side is connected to the guide gear 13, and the main shaft of the first driving motor 15 on the other side is provided with a guide gear 2 14. The adjusting gear 25 can move closer to the guide gear 2 14 as the adjusting shaft 22 and the follower seat 23 move until the adjusting gear 25 is meshed with the guide gear 2 14.

[0042] Subsequently, under the driving force generated by the operation of the first driving motor 15, the guide gear 2 14 can be engaged with the adjusting gear 25 to rotate, and further, the adjusting shaft 22 can be rotated, so that the horizontal cleaning scraper 3 and the vertical cleaning scraper 4 can switch positions and enter the interior of the high-pressure storage tank again to perform cleaning operations in different directions on the dirt inside the high-pressure storage tank.

[0043] When the horizontal cleaning scraper 3 and the vertical cleaning scraper 4 switch positions, the follower seat 23, the adjustment shaft 22 and the connecting ring 21 have moved away from the inner wall of the high-pressure storage tank. Therefore, when the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 after switching positions are lowered into the high-pressure storage tank, a certain gap is left between the scraper and the inner wall of the high-pressure storage tank, which effectively avoids the phenomenon of the scraper rubbing against the inner wall of the high-pressure storage tank and improves the stability of the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 when they are lowered into the high-pressure storage tank.

[0044] When the horizontal cleaning scraper 3, the vertical cleaning scraper 4 and the probe frame 1 are lowered into the high-pressure storage tank, the first drive motor 15 drives the guide gear 13 to rotate again, and the guide rack 24, the follower seat 23, the adjustment shaft 22 and the connecting ring 21 meshing therewith can be reset to their original positions until the scraper abuts against the inner wall of the high-pressure storage tank, waiting for the rotation of the probe frame 1, and then the cleaning operation can be carried out on the inner wall of the high-pressure storage tank.

[0045] like Fig. 9As shown, the follower seat 23 is provided with a limiting roller 27, and the support bar 11 is provided with a channel that can accommodate the movement of the limiting roller 27. When the follower seat 23 moves, the connection between the limiting roller 27 and the support bar 11 can prevent the follower seat 23 from deflecting, thereby ensuring the linearity of the follower seat 23 during movement.

[0046] Embodiment 2:

[0047] In order to enable the horizontal cleaning scraper 3 and the vertical cleaning scraper 4 to move to different depths in the high-pressure storage tank to perform cleaning operations, multiple probe frames 1 are connected to the same bracket 6 through a connecting rod 5, and two parallel guide arms 61 are provided on the bracket 6. A linkage rack frame 62 is provided on one side of one of the guide arms 61, and a driving gear 7 meshing with the linkage rack frame 62 is provided on the linkage rack frame 62, and a support frame 71 is provided on the driving gear 7, and a second driving motor 72 that can control the rotation of the driving gear 7 is provided outside the support frame 71.

[0048] When the second driving motor 72 drives the driving gear 7 to rotate, under the meshing force of the driving gear 7 and the linkage rack frame 62, the two guide arms 61 can move synchronously, so as to achieve the purpose of driving the bracket 6, the connecting rod 5 and the multiple probe frames 1 to move synchronously, so that the horizontal cleaning scraper 3 and the vertical cleaning scraper 4 can move to different depths in the high-pressure storage tank to perform cleaning operations.

[0049] like Figure 6 As shown, two sets of guide rollers 73 are provided on the support frame 71, and the two guide arms 61 pass through the support frame 71, and the two sets of guide rollers 73 respectively pass through the guide arms 61. When the guide arm 61 moves under the meshing force of the driving gear 7 of the linkage rack frame 62, the guide rollers 73 can prevent the guide arm 61 from deflecting and shaking, thereby ensuring the linearity of the guide arm 61, the bracket 6 and the probe frame 1 in the moving state.

[0050] like Figure 1 , Figure 2 As shown, in order to enable the transverse cleaning scraper 3 and the vertical cleaning scraper 4 to continuously clean different positions of the high-pressure storage tank, a driving shaft 74 that can rotate synchronously therewith is provided on the support frame 71, and a support plate 9 is provided above the support frame 71, and a third driving motor 75 that can control the rotation of the driving shaft 74 is provided on the support plate 9. Whether the transverse cleaning scraper 3 or the vertical cleaning scraper 4 performs a cleaning operation in the high-pressure storage tank, under the drive of the third driving motor 75, the transverse cleaning scraper 3 or the vertical cleaning scraper 4 can adjust the angle and rotate to different positions inside the high-pressure storage tank to perform the cleaning operation.

[0051] The nozzles 8 are all mounted on the support plate 9 to spray the cleaning agent inside the high-pressure storage tank to perform the flushing operation. In order to ensure the stability of the entire device, a movable frame 10 is provided at the bottom of the support plate 9. The frame 10 can carry the device and move to different positions until it is connected to the high-pressure storage tank.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
