Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a tank circumferential seam welding device for manufacturing fermentation tanks. Background Technology

[0002] Fermentation tanks are commonly used storage and reaction vessels in bioengineering, food brewing, and chemical production. Their manufacturing quality directly affects the equipment's sealing performance, structural strength, and service life. The tank body is typically assembled from multiple cylindrical sections welded together, with circumferential welding being a crucial process in tank forming. Circumferential welding equipment is a specialized device used to automatically weld the circumferential seams of the tank body. Its core function is to ensure that the welding torch moves at a uniform speed along the circumferential seam of the tank, maintaining a stable relative position between the welding torch and the weld seam, thereby guaranteeing consistent weld quality. Traditional circumferential welding often relies on manual operation or simple tooling, resulting in low welding precision, low efficiency, and high labor intensity.

[0003] For example, application number "CN202211417217.3" discloses a circumferential seam welding machine. By setting up a recessed groove, a welding torch assembly, and a shielding assembly, it addresses the issue that during the welding process, a significant amount of welding spatter is generated. Since the weld joint connects the inside and outside of the welding station, there is still a considerable risk of spatter ejection. Therefore, a shielding assembly is installed, which can be opened and closed flexibly to protect workers and create a safe working environment. However, existing circumferential seam welding equipment still has limitations in adapting to tanks of different diameters, rapid centering and leveling, and overall equipment stability. For instance, during clamping and positioning, multiple manual adjustments are often required to achieve concentric alignment between the tank and the welding mechanism, which is time-consuming and labor-intensive. During welding, vibration can easily cause the welding torch to shift, affecting the weld quality. Furthermore, most equipment has a fixed structure, making disassembly, assembly, and transportation inconvenient and difficult to adapt to frequent site changes or limited work environments. Therefore, there is an urgent need for a tank circumferential welder that can quickly position and clamp, has a self-stabilizing function, and is easy to disassemble and transport, so as to further improve the efficiency and accuracy of welding operations. Summary of the Invention

[0004] This invention provides a tank body circumferential weld equipment for manufacturing fermentation tanks, which solves the problems mentioned in the background art above.

[0005] Technical Solution: To achieve the above objectives, the present invention is implemented through the following technical solution: a tank body circumferential welding device for manufacturing fermentation tanks, comprising a base, the base being ring-shaped, and further comprising: a welding mechanism disposed above the base; an adjustment mechanism fixedly installed on the upper surface of the base; wherein the welding mechanism comprises a support column, the support column being fixedly inserted into the upper surface of the base, wherein four support columns are fixedly spaced around the upper surface of the base, and a top ring is fixedly inserted into the top of the support column.

[0006] According to one embodiment of the present invention, an mounting ring is provided above the base, the mounting ring and the base are arranged with the same central axis, a rotating ring is rotatably connected to the upper surface of the mounting ring, a welding machine is slidably connected to the side surface of the rotating ring, a connecting frame is fixedly installed on the outer surface of the rotating ring, and the outer side of the welding machine is simultaneously slidably connected to the inner surface of the connecting frame.

[0007] According to one embodiment of the present invention, a mounting frame is fixedly connected to the bottom surface of the mounting ring, a No. 1 motor is fixedly connected to the bottom of the mounting frame, a drive wheel is rotatably connected to the output end of the No. 1 motor, a mating ring is fixedly connected to the inner surface of the rotating ring, the outer surface of the mating ring is rotatably connected to the inner surface of the mounting ring, and the drive wheel is rotatably connected to the mating ring.

[0008] According to one embodiment of the present invention, the adjusting mechanism includes a connecting column, which is fixedly connected to the lower surface of the mounting ring, and the connecting column is fixedly spaced at four intervals. A sliding plate is rotatably connected to the connecting column, and a sliding groove is formed through the upper surface of the support column. The sliding groove is convex, and the end of the sliding plate away from the connecting column is slidably connected in the sliding groove of the support column.

[0009] According to one embodiment of the present invention, three sliding plates are provided on the bottom surface of the mounting ring, and a movable plate is rotatably connected to the outer surface of the connecting column, the outer end of the movable plate being slidably connected in the groove.

[0010] According to one embodiment of the present invention, a second motor is fixedly connected to the upper surface of the top ring, and a drive rod is rotatably connected to the output end of the second motor. The drive rod is configured as a threaded rod, and a threaded connection is made between the drive rod and the moving plate. The bottom of the drive rod is rotatably connected to the upper surface of the base.

[0011] According to one embodiment of the present invention, an arc-shaped groove is formed on the inner surface of the mounting ring, and a compression bladder is fixedly installed on the inner surface of the arc-shaped groove. The compression bladder is strip-shaped, and a slider is fixedly connected to the end of the compression bladder. The slider is slidably connected in the arc-shaped groove, and the slider is magnetic. Initially, the slider is magnetically attracted to the lower surface of the rotating ring.

[0012] According to one embodiment of the present invention, an installation groove is provided on the outer surface of the sliding plate, an expansion bladder is fixedly installed in the installation groove, a stabilizing block is fixedly connected to the outer surface of the expansion bladder, the stabilizing block is slidably connected in the installation groove, and the internal cavity of the expansion bladder communicates with the internal cavity of the compression bladder.

[0013] According to one embodiment of the present invention, a slide rod is fixedly connected through the side surface of the base, and a fixing plate is slidably connected to the inner end of the slide rod. The fixing plate is provided with four fixed intervals around the central axis of the base. A threaded handle is also threadedly connected to the side surface of the fixing plate. Insertion rods are slidably inserted into both ends of the fixing plate, wherein the fixing plate and the insertion rods are combined to form a ring.

[0014] The entire device is lowered from above the tank using a crane, allowing the base to pass through the tank and finally land on the ground. At this point, the mounting ring is also located on the outside of the tank. After adjusting the distance between the welding machine and the weld seam of the tank, the first motor can be started. The welding machine is started simultaneously after the first motor starts. When the first motor starts, it will drive the drive wheel to rotate, which in turn drives the mating ring at the bottom of the rotating ring to rotate, thereby driving the rotating ring to rotate, so that the welding machine rotates along the tank to weld the seam.

[0015] Beneficial effects: This invention provides a tank body circumferential welder for fermentation tank manufacturing. It has the following beneficial effects: (I) The tank body circumferential welding equipment manufactured in this fermentation tank solves the drawback of frequent position adjustments required by manual welding when welding large tanks, greatly improving welding efficiency and work safety. When the entire equipment is placed on the outside of the tank body, the threaded handle can be rotated. The threaded handle is threadedly connected to the fixed plate, while the other three fixed plates are slidably connected to the slide rod. The fixed plates are slidably inserted into each other through the plug rod. As the threaded handle is rotated, the four fixed plates begin to contract, eventually covering and clamping the bottom outer surface of the tank body. This ensures that the mounting ring and the tank body are on the same central axis, thereby ensuring that the distance between the welding machine and the weld seam is fixed when the rotating ring rotates. This greatly improves the overall welding accuracy of the equipment and avoids the occurrence of incomplete or missing welds. (II) The tank body circumferential weld equipment manufactured for this fermentation tank can start the No. 2 motor after the fixed plate has clamped the tank body and the distance of the electric welder has been adjusted. The No. 2 motor starts to drive the drive rod to rotate. Since the drive rod and the moving plate are connected by a thread, the moving plate then drives the mounting ring to move up and down along the support column, thereby quickly completing the up and down adjustment of the electric welder. This allows the electric welder to quickly be on the same horizontal plane as the weld seam, thus greatly shortening the adjustment time of this equipment and further improving the welding efficiency of this equipment. (III) The tank body circumferential welding equipment of this fermentation tank has both the upper and lower ends of the support column in an insert state. At the same time, the sliding plate and moving plate at the bottom of the mounting ring are also in a sliding insert state with the support column, which makes the whole equipment quick and easy to disassemble. This greatly reduces the loading space and storage space of the equipment during transportation, which is conducive to the overall storage of the equipment. When the rotating ring rotates, it will first use magnetism to drive the slider to slide in the arc groove, thereby squeezing the extrusion bladder. The extrusion bladder will transfer its internal air pressure to the expansion bladder, which will then push the stabilizing block to slide outward along the mounting groove. Finally, it will be squeezed against the inner surface of the sliding groove of the support column to fix the sliding plate. This avoids the problem of the mounting ring vibrating significantly and reducing the welding accuracy due to the vibration generated by the equipment during the welding process.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] Second embodiment: as follows Figures 1 to 8 As shown, the adjustment mechanism 3 includes a connecting column 31, which is fixedly connected to the lower surface of the mounting ring 23. The connecting column 31 is fixedly spaced in four places. A sliding plate 32 is rotatably connected to the connecting column 31. A sliding groove 33 is provided through the upper surface of the support column 21. The sliding groove 33 is convex. The end of the sliding plate 32 away from the connecting column 31 is slidably connected in the sliding groove 33 of the support column 21.

[0023] Three sliding plates 32 are provided on the bottom surface of the mounting ring 23. A movable plate 34 is also rotatably connected to the outer surface of the connecting column 31. The outer end of the movable plate 34 is also slidably connected in the groove 33.

[0024] A second motor 35 is fixedly connected to the upper surface of the top ring 22. A drive rod 36 is rotatably connected to the output end of the second motor 35. The drive rod 36 is a threaded rod. The drive rod 36 and the moving plate 34 are connected by a thread. The bottom of the drive rod 36 is rotatably connected to the upper surface of the base 1.

[0025] An arc-shaped groove 37 is provided on the inner surface of the mounting ring 23. A compression bladder 38 is fixedly installed on the inner surface of the arc-shaped groove 37. The compression bladder 38 is strip-shaped. A slider 39 is fixedly connected to the end of the compression bladder 38. The slider 39 is slidably connected in the arc-shaped groove 37. The slider 39 is magnetic. Initially, the slider 39 is magnetically attracted to the lower surface of the rotating ring 24.

[0026] An installation groove 310 is provided on the outer surface of the sliding plate 32. An expansion bladder 311 is fixedly installed in the installation groove 310. A stabilizing block 312 is fixedly connected to the outer surface of the expansion bladder 311. The stabilizing block 312 is slidably connected in the installation groove 310. The internal cavity of the expansion bladder 311 is connected to the internal cavity of the compression bladder 38.

[0027] A slide rod 313 is fixedly connected through the side surface of the base 1. A fixing plate 314 is slidably connected to the inner end of the slide rod 313. Four fixing plates 314 are fixedly spaced around the central axis of the base 1. A threaded handle 315 is threadedly connected to the side surface of the fixing plate 314. Insertion rods 316 are slidably inserted into both ends of the fixing plate 314. The fixing plate 314 and the insertion rods 316 are combined to form a ring.

[0028] During operation, the entire device is lowered from above the tank using a crane, allowing the base 1 to pass through the tank and finally land on the ground. At this point, the mounting ring 23 is also positioned on the outside of the tank. After adjusting the distance between the welding machine 25 and the weld seam on the tank, the first motor 28 is started. The welding machine 25 starts synchronously with the first motor 28. The start of the first motor 28 drives the drive wheel 29 to rotate, which in turn drives the mating ring 210 at the bottom of the rotating ring 24 to rotate, thus rotating the rotating ring 24. This causes the welding machine 25 to rotate along the tank to weld the seam. This method solves the problem of frequent manual adjustments required when welding large tanks, significantly improving welding efficiency and performance. For operational safety, the threaded handle 315 can be rotated when the entire device is positioned outside the tank. The threaded handle 315 is threadedly connected to the fixing plate 314, while the other three fixing plates 314 are slidably connected to the slide rod 313. The fixing plates 314 are also slidably interlocked through the insertion rod 316. As the threaded handle 315 rotates, the four fixing plates 314 begin to retract, ultimately covering and clamping the bottom outer surface of the tank. This ensures that the mounting ring 23 and the tank are aligned on the same central axis, thus maintaining a fixed distance between the welding machine 25 and the weld seam as the rotating ring 24 rotates. This significantly improves the overall welding accuracy of the device and prevents incomplete or missed welds. After the fixed plate 314 clamps the tank and the distance of the welding machine 25 is adjusted, the second motor 35 can be started. The second motor 35 drives the drive rod 36 to rotate. Since the drive rod 36 and the moving plate 34 are threadedly connected, the moving plate 34 drives the mounting ring 23 to move up and down along the support column 21, thereby quickly completing the up and down adjustment of the welding machine 25. This allows the welding machine 25 to quickly be level with the weld seam, significantly shortening the adjustment time of the equipment and further improving the welding efficiency. Both ends of the support column 21 are in an insert state, and the sliding plate 32 at the bottom of the mounting ring 23 and the moving plate 34 are also in a sliding insert state with the support column 21. This allows the entire device to be quickly disassembled, significantly reducing the loading and storage space during transportation and facilitating overall storage. When the rotating ring 24 rotates, it first uses magnetism to drive the slider 39 to slide within the arc-shaped groove 37, thereby squeezing the compression bladder 38. This causes the compression bladder 38 to transfer its internal air pressure to the expansion bladder 311, which then pushes the stabilizing block 312 outward along the mounting groove 310. Finally, the block is pressed against the inner surface of the sliding groove 33 of the support column 21, fixing the sliding plate 32. This prevents the mounting ring 23 from vibrating significantly and reducing welding accuracy due to vibrations generated during equipment operation.
