Description

Technical Field

[0001] This utility model relates to the field of tank inner wall cleaning, specifically a rotating swing arm spray bar for tank wall surface. Background Technology

[0002] The rotating swing arm spray bar for tank walls is a device specifically designed for automated cleaning or spraying inside large vertical storage tanks (such as reactors, mixing tanks, fermentation tanks, and liquid storage tanks). It consists of one or more rotatable spray arms. Before use, the spray bar needs to be installed on the tank body and then connected to an external supply pipeline through a rotary joint. The spray arms can rotate or swing inside the tank, thereby covering the inner wall of the tank with cleaning fluid or process liquid in the form of a high-speed jet, covering all directions and eliminating dead angles, so as to achieve the purpose of cleaning the inner wall of the tank.

[0003] The existing rotating arm spray bar on the tank wall relies on multiple bolts to connect to the tank flange during installation. This requires manual alignment of multiple bolt holes and tightening of each bolt individually. Disassembly also requires removing each bolt individually. This process is cumbersome, especially for large tanks where the bolts are larger and more numerous, significantly increasing the installation difficulty. It usually requires multiple people working together for a long time to complete, seriously affecting the efficiency of equipment assembly and disassembly and increasing labor and time costs. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rotating swing arm spray bar on the tank wall to solve the technical problem of inconvenience in quickly disassembling and assembling the rotating swing arm spray bar.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotating swing arm spray bar for a tank wall, comprising a tank body, a flange mounted on the top of the tank body with multiple flange holes, an mounting plate placed on the top of the tank body, and a cover plate fixed to the outer wall of the mounting plate, a limit ring threadedly connected to the outer wall of the cover plate, multiple insert rods fixed to the bottom of the cover plate, each insert rod having a locking hole, and a locking pin inserted into the locking hole, one end of the locking pin penetrating to the outside of the flange and mounted with a pressure rod, a spring installed between the locking pin and the cover plate, the bottom of the limit ring and one end of the pressure rod both being inclined, and one end of the pressure rod abutting against the inner wall of the limit ring.

[0006] By adopting the above technical solution, complex interfaces are avoided from being directly machined on the tank body. The positioning foundation of the mounting plate is achieved through the flange holes, and the cooperation between the insert rod and the flange holes replaces the cumbersome steps of traditional bolt alignment, thus quickly completing the installation and positioning.

[0007] Furthermore, the outer wall of the insertion rod is provided with an anti-slip ring, and the outer wall of the anti-slip ring fits against the inner wall of the flange hole, and the anti-slip ring is made of fluororubber material.

[0008] By adopting the above technical solution, the friction between the insertion rod and the flange hole is increased, thereby improving the stability of the mounting plate after installation.

[0009] Furthermore, the top of the mounting plate is fixed with two support plates, and a rotating shaft is connected between the two support plates via a bearing. A first housing is installed between the two rotating shafts. The top of the mounting plate is also provided with an opening, the size of which is larger than the size of the first housing.

[0010] By adopting the above technical solution, the setting of the rotating shaft facilitates the rotation of the first housing, which in turn drives the spray bar to rotate, allowing the spray bar to rotate and swing.

[0011] Furthermore, a second housing is installed on the top of the mounting plate, a hydraulic cylinder is installed on one side of the second housing, and a rack is installed on the output end of the hydraulic cylinder via a piston rod.

[0012] By adopting the above technical solution, when the shaft needs to rotate, the hydraulic cylinder can be activated. The operation of the hydraulic cylinder can extend the piston rod, thereby driving the rack to move, so as to adjust the position of the rack.

[0013] Furthermore, a slide rod is installed inside the second housing, and a slide block is fitted on the outer wall of the slide rod, with the top of the slide block being fixedly connected to the bottom of the rack.

[0014] By adopting the above technical solution, the rack can drive the slide block to slide on the slide rod when it moves, thereby improving the stability of the rack when it moves.

[0015] Furthermore, one end of one of the shafts extends into the interior of the second housing and is fitted with a gear, the rack meshing with the gear.

[0016] By adopting the above technical solution, the movement of the rack will drive the gear to rotate, which in turn will drive the shaft connected to the gear to rotate, and then drive the first housing to rotate.

[0017] Furthermore, a motor is installed on one side of the interior of the first housing, and the output end of the motor is connected to a drive bevel gear. A spray bar is connected to the interior of the first housing via a bearing, and multiple nozzles are installed on the outer wall of the spray bar.

[0018] By adopting the above technical solution, when the spray bar needs to be rotated, the motor can be started. The motor can drive the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate.

[0019] Furthermore, a mounting bracket is fixed to the top of the first housing, an infusion tube is fixed on the mounting bracket, and a flange is installed at the top of the infusion tube.

[0020] By adopting the above technical solution, the flange is conveniently connected to the external liquid supply pipeline, and the external cleaning fluid can enter the infusion pipe and then enter the channel of the spray bar.

[0021] Furthermore, a rotary joint is installed between the spray rod and the infusion tube, and a driven bevel gear is installed on the outer wall of the spray rod, with the driving bevel gear meshing with the driven bevel gear.

[0022] By adopting the above technical solution, when the driven bevel gear rotates, it will drive the spray rod to rotate. The rotary joint is designed so that only the spray rod can rotate while the infusion tube cannot rotate.

[0023] Furthermore, the locking pin is adapted to the locking hole, and the insertion rod is adapted to the flange hole.

[0024] By adopting the above technical solution, after the locking pin is inserted into the locking hole, the insertion rod can be locked and limited to prevent the locking pin from moving at will.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, by incorporating a plug rod, locking holes, locking posts, springs, pressure rods, and limiting rings, simplifies installation. During installation, simply insert the plug rod into the flange hole, then rotate the limiting ring to move it downwards and push the pressure rod. The pressure rod then pushes the locking post to move, compressing the spring. The locking post engages with the corresponding locking hole, locking the plug rod in place. This completes the installation of the mounting plate, eliminating the need to align multiple bolt holes and tighten them individually, simplifying the process. During disassembly, simply rotate the limiting ring in the opposite direction to release it from the pressure rod. The spring then stretches, pushing the locking post back to its original position, allowing it to move out of the locking hole and release the locking mechanism on the plug rod. This method improves the efficiency of mounting plate assembly and disassembly, avoiding the time-consuming process of installing or removing the mounting plate.

[0027] 2. By incorporating an anti-slip ring, this utility model can improve the stability of the insertion rod after it is inserted into the flange hole. At the same time, the limiting ring can tighten and limit the pressure rod to prevent it from moving freely, thereby ensuring that the locking pin can be firmly locked into the locking hole and improving the limiting effect of the locking pin.

[0028] 3. This utility model is equipped with a hydraulic cylinder, rack, gear, slide block and slide rod. When the housing and spray rod need to swing, the hydraulic cylinder can be activated. The operation of the hydraulic cylinder can extend and retract the piston rod, thereby driving the rack to move. The rack drives the gear to rotate, which in turn drives the rotating shaft to rotate, so that the first housing and spray rod can rotate around the rotating shaft. The slide block and slide rod can guide the rack, thereby improving the stability of the rack when it moves. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The embodiments of this utility model will be described below based on its overall structure.

[0041] Example 1:

[0042] A rotating swing arm spray bar on the tank wall, such as Figures 1-9As shown, the tank includes a tank body 1. Three supports are installed on the lower part of the outer wall of the tank body 1, and the three supports are arranged in a triangular pattern. A drain valve is installed at the bottom of the tank body 1. A flange 2 is installed on the top of the tank body 1, and multiple flange holes 4 are opened on the flange 2. An installation plate 3 is placed on the top of the tank body 1, and a cover plate 23 is fixed to the outer wall of the installation plate 3. A limit ring 31 is threadedly connected to the outer wall of the cover plate 23. Multiple insert rods 25 are fixed to the bottom of the cover plate 23. A locking hole 27 is opened on the insert rod 25, and a locking post 26 is inserted into the locking hole 27. One end of the locking post 26 extends to the outside of the flange 2 and is equipped with a pressure rod 30. A spring 29 is installed between the locking post 26 and the cover plate 23. The spring 29 is made of 304 stainless steel or 316L stainless steel.

[0043] See Figures 1-8 The bottom of the limiting ring 31 and one end of the pressure rod 30 are both set at an angle. One end of the pressure rod 30 abuts against the inner wall of the limiting ring 31, avoiding the need to directly process complex interfaces on the tank body 1. The positioning basis of the mounting plate 3 is realized through the flange hole 4, and the cooperation between the insert rod 25 and the flange hole 4 replaces the cumbersome steps of traditional bolt alignment, quickly completing the installation and positioning. The locking post 26 is adapted to the locking hole 27. The end of the locking post 26 is provided with a fluororubber gasket to fill the gap of the locking hole 27 and absorb vibration. The insert rod 25 is adapted to the flange hole 4. After the locking post 26 is inserted into the locking hole 27, it can lock and limit the insertion rod 25 to prevent the locking post 26 from moving at will. The outer wall of the limiting ring 31 is equipped with multiple anti-slip protrusions, and the inner wall of the limiting ring 31 is provided with an anti-slip pad made of fluororubber material. The anti-slip pad fits against the outer wall of the cover plate 23, making it convenient for the operator to rotate the limiting ring 31. Both the limiting ring 31 and the pressure rod 30 are made of 304 stainless steel or 316L stainless steel. The inclined surfaces of the limiting ring 31 and the pressure rod 30 are plated with a nitrided layer (hardness of HV800 or above) to reduce friction and wear.

[0044] See Figures 1-8The top of the mounting plate 3 has two support plates 15 fixed, and a rotating shaft 16 is connected between the two support plates 15 via bearings. A first housing 5 is installed between the two rotating shafts 16. The top of the mounting plate 3 also has an opening 24, the size of which is larger than the size of the first housing 5. The first housing 5 is rotatably connected to the support plates 15 via the rotating shafts 16. The rotating shafts 16 facilitate the rotation of the first housing 5, which in turn drives the spray bar 13 to rotate, allowing the spray bar 13 to rotate and swing. A first cover plate 9 is bolted to one side of the first housing 5. A second housing 22 is also installed on the top of the mounting plate 3. A hydraulic cylinder 18 is installed on one side, and a rack 19 is installed on the output end of the hydraulic cylinder 18 through the piston rod. When the rotating shaft 16 needs to be rotated, the hydraulic cylinder 18 can be activated. The operation of the hydraulic cylinder 18 can extend the piston rod and drive the rack 19 to move so as to adjust the position of the rack 19. One end of the rotating shaft 16 extends into the interior of the second housing 22 and is equipped with a gear 17. The rack 19 meshes with the gear 17. The movement of the rack 19 will drive the gear 17 to rotate, which in turn drives the rotating shaft 16 connected to the gear 17 to rotate, and then drives the first housing 5 to rotate. A second cover plate is installed on the outer surface of the second housing 22 by bolts.

[0045] See Figures 1-5 A motor 6 is installed inside one side of the first housing 5, and the output end of the motor 6 is connected to a drive bevel gear 7. A spray rod 13 is connected inside the first housing 5 via a bearing, and multiple nozzles 14 are installed on the outer wall of the spray rod 13. The spray rod 13 is a hollow rod. When the spray rod 13 needs to be rotated, the motor 6 can be started. The operation of the motor 6 can drive the drive bevel gear 7 to rotate, which in turn drives the driven bevel gear 8 to rotate. A fixing frame 11 is fixed on the top of the first housing 5, and an infusion tube 12 is fixed on the fixing frame 11. A flange is installed on the top end of the infusion tube 12. The flange is designed for easy connection to the outside. The system is connected to the liquid supply line, allowing external cleaning fluid to enter the infusion pipe 12 and then into the channel of the spray rod 13. A rotary joint 10 is installed between the spray rod 13 and the infusion pipe 12. A driven bevel gear 8 is installed on the outer wall of the spray rod 13, and the driving bevel gear 7 meshes with the driven bevel gear 8. When the driven bevel gear 8 rotates, it will drive the spray rod 13 to rotate. The rotary joint 10 ensures that only the spray rod 13 can rotate while the infusion pipe 12 cannot rotate. The hydraulic cylinder 18 and the motor 6 are both electrically connected to the external control panel to control the operation of the hydraulic cylinder 18 and the motor 6.

[0046] Example 2:

[0047] Based on the above embodiment 1, in order to improve the stability of the insertion rod 25 into the flange hole 4, the following structure will be set.

[0048] Specifically, the outer wall of the insertion rod 25 is provided with an anti-slip ring 28, and the outer wall of the anti-slip ring 28 fits against the inner wall of the flange hole 4. The anti-slip ring 28 is made of fluororubber material, which increases the friction between the insertion rod 25 and the flange hole 4 and improves the stability of the installation plate 3 after installation.

[0049] Example 3:

[0050] Based on the above embodiment 1, in order to improve the stability of the rack 19 when it moves, it is necessary to guide the rack 19, so the following structure will be set.

[0051] Specifically, a slide rod 20 is installed inside the second housing 22, and a slide seat 21 is fitted on the outer wall of the slide rod 20. The top of the slide seat 21 is fixedly connected to the bottom of the rack 19. The rack 19 is slidably connected to the slide rod 20 through the slide seat 21. When the rack 19 moves, it can drive the slide seat 21 to slide on the slide rod 20, thereby improving the stability of the rack 19 when it moves.

[0052] The working principle of this utility model is as follows: First, the operator aligns the mounting plate 3, which integrates the spray bar 13, the first housing 5, and the second housing 22, with the flange 2 on the top of the tank 1, so that the insert rod 25 at the bottom of the cover plate 23 is inserted into the flange hole 4 of the flange 2, while the fluororubber anti-slip ring 28 is attached to the inner wall of the flange hole 4 for initial anti-slip positioning; then, the limiting ring 31 on the outer wall of the cover plate 23 is rotated clockwise. Since the bottom of the limiting ring 31 and one end of the pressure rod 30 are both inclined, when the limiting ring 31 moves down, it squeezes the pressure rod 30 through the inclined surface, which drives the locking post 26 to compress the spring 29. When the insert rod 25 is inserted into the locking hole 27 and aligned with the locking post 26, the spring 29 releases the preload, pushing the locking post 26 into the locking hole 27, thus completing the rigid locking of the insert rod 25; at the same time, the limiting ring 31 continues to rotate until it is close to the surface of the flange 2, and the inclined surface continuously abuts against the pressure rod 30 to prevent the locking post 26 from loosening;

[0053] Then, the hydraulic cylinder 18 on one side of the second housing 22 is activated via the external control panel. The hydraulic cylinder 18 drives the piston rod to extend and retract, causing the rack 19 to move horizontally. The slide block 21 at the bottom of the rack 19 slides along the slide rod 20 to ensure that the rack moves smoothly without deviation. The rack 19 meshes with the gear 17 on the rotating shaft 16, and the linear motion of the rack 19 is converted into the rotational motion of the gear 17, which in turn drives the rotating shaft 16 to rotate around the support plate 15. The rotating shaft 16 drives the first housing 5 and the spray bar 13 to swing around the rotating shaft 16 (the size of the opening 24 of the mounting plate 3 is larger than that of the first housing 5 to avoid interference). When the swing reaches the appropriate position, the hydraulic cylinder 18 can be turned off.

[0054] The external supply hose is connected through the flange at the top of the infusion tube 12. When the valve is opened, the cleaning fluid is delivered to the rotary joint 10 through the infusion tube 12. The rotary joint ensures that the infusion tube 12 is fixed when the spray rod 13 rotates, thus preventing the tube from getting tangled. The motor 6 inside the first housing 5 is started. The output end of the motor 6 drives the active bevel gear 7 to rotate. The active bevel gear meshes with the driven bevel gear 8 on the spray rod 13, causing the spray rod 13 to rotate at high speed around its own axis.

[0055] The cleaning fluid is delivered to multiple nozzles 14 via a rotating spray bar 13 and sprayed out at a high-speed jet pressure of 0.5MPa. Combined with the rotation of the spray bar 13 and the swing arm angle, the inner wall of the tank 1 is covered 360° without dead angles, thereby cleaning the inner wall of the tank 1.

[0056] When the spray device needs to be removed after cleaning, the operator rotates the limiting ring 31 counterclockwise. The limiting ring 31 moves upward, and the contact force between its inclined surface and the pressure rod 30 disappears. The spring 29 pushes the locking pin 26 to reset with the pressure rod 30. The locking pin disengages from the locking hole 27 of the insertion rod 25, releasing the locking of the insertion rod 25. Pull the mounting plate 3 upward to pull the insertion rod 25 out of the flange hole 4, completing the disassembly of the entire spray device.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
