Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical storage tank production, and in particular to a device for anti-corrosion treatment of the inner wall of a chemical storage tank. Background Technology
[0002] According to the patent document with announcement number CN219850324U, the controller starts the first motor, which drives the rotating shaft and the threaded rod to rotate clockwise through the bevel gear set. The clockwise rotation of the rotating shaft releases the hose, and the threaded rod drives the diversion chamber to slide down along the groove on the right end of the connecting plate through the support plate. At the same time, the controller introduces the anti-corrosion coating inside the anti-corrosion coating storage tank into the diversion chamber through the hose. Then, the diversion chamber evenly distributes the anti-corrosion coating into the five sets of corrugated expansion tubes. Finally, the atomizing nozzle evenly sprays the anti-corrosion coating inside the corrugated expansion tubes onto the inner wall of the chemical storage tank.
[0003] The patent document describes a device used to spray anti-corrosion coating onto the inner wall of a chemical storage tank. However, due to the limited height of the threaded rod, the movement height of the support plate, diversion chamber, and atomizing nozzle is also limited. This makes it very inconvenient to use for some taller chemical storage tanks. Furthermore, the four atomizing nozzles are positioned in four directions during spraying and do not twist. Although the position of the coating on the inner wall of the tank can be adjusted, the thickness of the anti-corrosion coating between adjacent atomizing nozzles may be inconsistent, potentially leading to inconsistent anti-corrosion effects on the inner wall of the chemical storage tank. Additionally, for chemical storage tanks with curved tops and bottoms, the device cannot spray the curved surfaces at the beginning and end of the spraying process. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:
[0028] like Figures 1-6 As shown, a chemical storage tank inner wall anti-corrosion treatment device includes a cantilever crane 4, a paint tank 5 is provided on one side of the cantilever crane 4, a supply pump 6 is provided on the paint tank 5, a spraying mechanism 3 is provided at the discharge end of the supply pump 6, and also includes a lifting mechanism 1 and an adjusting mechanism 2. The lifting mechanism 1 is located in front of the lifting mechanism 1, and the adjusting mechanism 2 is located outside the lifting mechanism 1.
[0029] In this embodiment: the lifting mechanism 1 includes a base plate 11, with two symmetrical arc-shaped side plates 12 fixed to the top of the base plate 11. A top plate 13 is fixed to the top of the two arc-shaped side plates 12. A screw 16 is rotatably connected between the base plate 11 and the top plate 13. A lifting plate 17 is threadedly connected to the outside of the screw 16. The lifting plate 17 is slidably connected between the two arc-shaped side plates 12. A zigzag groove is provided on the side of each arc-shaped side plate 12 that is far apart from each other. The screw 16 is located in the middle of the two arc-shaped side plates 12. A drive motor 15 is fixedly installed at the input end of the screw 16. The fixed part of the drive motor 15 is fixedly connected to the bottom of the base plate 11. A lifting hook 14 is fixedly installed on the top of the top plate 13. The hook on the cantilever crane 4 is fastened to the lifting hook 14. The drive motor 15 drives the screw 16 to rotate. The rotation of the screw 16 drives the lifting plate 17 to move upward along the position between the two arc-shaped side plates 12. The upward movement of the lifting plate 17 drives the adjusting mechanism 2 to move from the base plate 11 to the top plate 13.
[0030] In this embodiment: the adjusting mechanism 2 includes a lifting seat 21, which is sleeved on the outside of two arc-shaped side plates 12. The inner ring of the lifting seat 21 is rotatably connected to a limiting post 22 at a zigzag groove. The lifting seat 21 has six first extension arms 23 arranged in a ring. Each first extension arm 23 has a second extension arm 24 hinged to one end away from the lifting seat 21. Each first extension arm 23 has a first electric push rod 25 on its lower side and a second electric push rod 26 on both sides of each first extension arm 23. The inner ring of the lifting seat 21 has arc-shaped grooves on both sides of the two limiting posts 22. The end of the lifting plate 17 extending out of the two arc-shaped side plates 12 is slidably connected to the arc-shaped groove. The fixed part of the first electric push rod 25 is rotatably connected to the bottom of the lifting seat 21. The telescopic part of the first electric push rod 25 is hinged to the middle position of the first extension arm 23. The fixed part of the second electric push rod 26 is hinged to the first extension arm 24. The extension arm 23 is hinged to the side, and the telescopic part of the second electric push rod 26 is hinged to the side of the second extension arm 24. The upward movement of the lifting seat 21 causes the limiting post 22 to move in the zigzag groove of the arc-shaped side plate 12. At the same time, the lifting seat 21 swings back and forth in the circumferential direction under the drive of the limiting post 22. Then, the lifting seat 21 swings back and forth in the circumferential direction in sync during the upward movement. The continuous movement of the lifting seat 21 drives the first extension arm 23, the second extension arm 24 and the spraying mechanism 3 to move synchronously. Then, the telescopic part of the first electric push rod 25 pushes the first extension arm 23 to swing up or down, thereby adjusting the height of the second extension arm 24. At the same time, the telescopic parts of the two second electric push rods 26 are used to push the second extension arm 24 to swing up and down, thereby adjusting the distance from the end of the second extension arm 24 to the inner wall of the chemical storage tank. Then, the spraying distance can be adjusted according to the diameter of the chemical storage tank.
[0031] In this embodiment: the spraying mechanism 3 includes a diversion ring pipe 32, a feed pipe 31 fixed to the top of the diversion ring pipe 32, six feeding branch pipes 33 fixed to the outside of the diversion ring pipe 32, a nozzle 34 fixed to the outlet end of the feeding branch pipe 33, a tilting seat 35 rotatably connected to the end of the second extension arm 24 away from the first extension arm 23, the tilting seat 35 being fixedly connected to the nozzle 34, a tilting motor 36 fixedly installed at the input end of the tilting seat 35, and the feed end of the feed pipe 31 being fixed to the outlet end of the supply pump 6, the feed end of the supply pump 6 being connected to the feed pipe via a feed pipe. The bottom of the paint bucket 5 is connected to a supply pump 6, which pumps the anti-corrosion paint in the paint bucket 5 through the feed pipe 31 to the diversion ring pipe 32. The diversion ring pipe 32 then diverts the anti-corrosion paint into six feed branch pipes 33, which in turn guide the anti-corrosion paint into the spray head 34. The spray head 34 then sprays the anti-corrosion paint onto the inner wall of the chemical storage tank. At the same time, the rotating part of the tilting motor 36 drives the tilting seat 35 to tilt at a certain angle on the second extension arm 24, thereby expanding the spraying range of the spray head 34.
[0032] Working principle: When in use, first place the chemical storage tank that needs to be treated for corrosion protection under the lifting mechanism 1, then align the lifting mechanism 1 with the opening of the chemical storage tank, and then use the cantilever crane 4 to send the lifting mechanism 1 down to the bottom of the chemical storage tank.
[0033] Subsequently, the telescopic part of the first electric push rod 25 pushes the first extension arm 23 to swing up or down, thereby adjusting the height of the second extension arm 24. Simultaneously, the telescopic parts of the two second electric push rods 26 push the second extension arm 24 to swing up and down, thereby adjusting the distance from the end of the second extension arm 24 to the inner wall of the chemical storage tank. The spraying distance can then be adjusted according to changes in the diameter of the chemical storage tank. Simultaneously, the rotating part of the drive motor 15 drives the screw 16 to rotate. The rotation of the screw 16 causes the lifting plate 17 to move upwards along the position between the two arc-shaped side plates 12. The upward movement of the lifting plate 17 causes the lifting seat 21 to move from the bottom plate 11 to the top plate 13. During this process, the upward movement of the lifting seat 21 causes the limiting post 22 to move within the zigzag groove of the arc-shaped side plate 12. At the same time, the lifting plate 17 and its ends... With the two arc-shaped grooves of the lifting seat 21 working together, the lifting seat 21 swings back and forth in the circumferential direction under the drive of the limiting column 22. Then, the lifting seat 21 swings back and forth in the circumferential direction in sync as it moves upward. The continuous movement of the lifting seat 21 drives the first extension arm 23, the second extension arm 24 and the spraying mechanism 3 to move synchronously. At the same time, the supply pump 6 pumps the anti-corrosion coating in the paint tank 5 through the feed pipe 31 to the diversion ring pipe 32 through the feed pipe. The anti-corrosion coating is diverted into the six feed branch pipes 33 through the diversion ring pipe 32. The anti-corrosion coating is introduced into the nozzle 34 through the six feed branch pipes 33. The anti-corrosion coating is sprayed onto the inner wall of the chemical storage tank through the nozzle 34. At the same time, the rotating part of the flipping motor 36 drives the flipping seat 35 to flip at a certain angle on the second extension arm 24, thereby expanding the spraying range of the nozzle 34.
[0034] When the lifting seat 21 moves to the bottom of the top plate 13, the lifting mechanism 1 is moved upward a certain distance by the cantilever crane 4, so that the lifting mechanism 1 is placed in the position of the unpainted chemical storage tank. Then, the rotating part of the drive motor 15 drives the screw 16 to rotate in the opposite direction, so that the lifting plate 17 moves the lifting seat 21 downward. At the same time, the above steps are repeated to spray the inner wall of the chemical storage tank.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
