Description

Technical Field

[0001] The present application relates to the technical field of submerged arc welding, and in particular to a flux recovery device. Background Art

[0002] Submerged arc welding is a welding method in which an electric arc burns under a layer of flux. During the submerged arc welding process, the workpiece is in a moving state, and the electric arc continuously melts the welding wire, flux and base material to form a molten pool, which forms a weld after solidification. The flux serves as a protective auxiliary material in the weld formation process. A part of it melts during the welding process to form liquid slag, which solidifies to form a hard slag shell covering the surface of the weld and needs to be knocked off manually using tools. The other part is not melted.

[0003] Submerged arc welding is currently used to weld the reinforcement ring and the head together. Since the head is in the shape of an outer arc surface, during the welding process of the reinforcement ring and the head, the flux is easy to fall along the outer arc surface of the head and around the head, which is inconvenient to recover the flux and affects the recovery efficiency of the flux, which needs to be improved. Utility Model Content

[0004] The purpose of the present application is to provide a flux recovery device in order to improve the recovery efficiency of the flux.

[0005] A flux recovery device provided in the present application adopts the following technical solution: it includes a recovery box, the recovery box is provided with a recovery chamber, the recovery box is connected to a recovery pipe connected to the recovery chamber, the inner wall of the recovery chamber is connected to a fan, the fan is connected to the recovery pipe, the recovery pipe is connected to an annular tube at one end away from the recovery box, the annular tube is provided with an annular channel connected to the recovery pipe, and the inner ring of the annular tube is provided with an opening channel connected to the annular channel.

[0006] By adopting the above technical solution, the reinforcement ring and the head are welded by submerged arc welding, and the excess flux rolls down along the outer arc surface of the head. The flux enters the annular channel from the opening channel, and the fan sucks the flux in the annular channel into the recovery box through the recovery pipe, which facilitates the recovery of the flux and improves the recovery efficiency of the flux.

[0007] Optionally, the annular channel is formed by splicing two annular grooves, the radius of the annular groove increases step by step along the groove body from the end far away from the recovery pipe to the end close to the recovery pipe, and the opening channel and the recovery pipe are both connected to the annular groove.

[0008] By adopting the above technical solution, part of the flux enters the end of the annular groove away from the recovery pipe through the open channel. Since the radius of the annular groove gradually increases along the groove body from the end away from the recovery pipe to the end close to the recovery pipe, this part of the flux rolls toward the recovery pipe under the influence of gravity, shortening the distance between the flux and the recovery pipe, making it easier for the fan to suck the flux in the annular channel into the recovery box through the recovery pipe, thereby improving the recovery efficiency of the flux.

[0009] Optionally, the annular groove includes a steep groove and a gentle groove, the gentle groove is located between the steep groove and the recovery pipe, the steep groove and the recovery pipe are both connected to the gentle groove, and the steep groove and the gentle groove are both connected to the opening channel.

[0010] By adopting the above technical solution, part of the flux enters the steep trough through the open channel. Since the inner wall of the steep trough is relatively steep, this part of the flux is easy to roll into the flat trough, shortening the distance between the flux and the recovery pipe, making it easier for the fan to suck the flux in the annular channel into the recovery box through the recovery pipe, thereby improving the recovery efficiency of the flux.

[0011] Optionally, the recovery box is connected to a first filter plate, and the recovery box is provided with a first slag discharge channel and a agent discharge channel which are connected to the recovery chamber, the first slag discharge channel is located between the agent discharge channel and the outlet of the recovery pipe, the first slag discharge channel corresponds to the first filter plate, the first filter plate is inclined, an end of the first filter plate away from the first slag discharge channel is higher than an end of the first filter plate close to the first slag discharge channel, and the recovery box is connected to a vibrator.

[0012] By adopting the above technical scheme, the flux and welding slag fall into the annular channel along the outer arc surface of the head, the fan sucks the flux and welding slag into the recovery chamber together, the flux and welding slag fall on the first filter plate from the outlet of the recovery pipe, the vibrator drives the recovery box to vibrate, the flux passes through the first filter plate and is discharged from the flux outlet channel; the welding slag moves along the first filter plate toward the direction close to the first slag outlet channel, and the welding slag is discharged from the first slag outlet channel, so that the flux and the welding slag are separated, thereby improving the recovery effect of the flux.

[0013] Optionally, the outlet of the recovery pipe is located at an end of the recovery box away from the first slag discharge channel.

[0014] By adopting the above technical solution, the flux and welding slag fall on the first filter plate away from the first slag discharge channel, which increases the distance between the flux and welding slag and the first slag discharge channel, that is, increases the movement path of the flux and welding slag on the first filter plate, and improves the screening effect of the flux and welding slag.

[0015] Optionally, a paving plate is slidably connected in the recovery chamber for driving the flux and welding slag to slide toward the first slag discharge channel, and the paving plate is located between the outlet of the retrieval pipe and the first filter plate. The recovery box is connected to a driving component for driving the paving plate to slide toward or away from the first slag discharge channel.

[0016] By adopting the above technical solution, after the flux and welding slag fall on the first filter plate, the driving component drives the paving plate to slide toward the direction close to the first slag discharge channel, and the paving plate abuts against the flux and welding slag and drives the flux and welding slag to be flattened toward the direction close to the first slag discharge channel, thereby preventing the accumulation of flux and welding slag and improving the screening effect of flux and welding slag.

[0017] Optionally, the driving assembly includes at least two gears rotatably connected to the recovery chamber and a toothed chain mounted on the gears, the toothed chain meshes with each of the gears, the recovery box is connected to a driving member for driving one of the gears to rotate, and the paving plate is fixedly connected to the toothed chain.

[0018] By adopting the above technical solution, the driving member drives one of the gears to rotate, and the gear drives the toothed chain to rotate, that is, the paving plate moves with the rotation of the toothed chain. When the paving plate is located on the side of the toothed chain close to the first filter plate and moves, the paving plate abuts against the flux and welding slag and drives the flux and welding slag to be paved in the direction close to the first slag discharge channel; when the paving plate is located on the side of the toothed chain away from the first filter plate and moves, the paving plate moves in the direction away from the first slag discharge channel, and the paving plate and the welding slag are staggered to prevent the paving plate from driving the welding slag to move in the direction away from the first slag discharge channel.

[0019] Optionally, the paving plate is connected to a guide column, and the recovery box is provided with a guide groove for slidingly cooperating with the guide column, and the guide groove is connected to the recovery chamber.

[0020] By adopting the above technical solution, when the paving plate slides, the guide column slides along the guide groove, and the sliding cooperation between the guide column and the guide groove guides and limits the sliding of the paving plate, thereby improving the sliding stability of the paving plate.

[0021] Optionally, the recovery box is connected to a second filter plate, which is located between the first filter plate and the agent outlet channel. The recovery box is provided with a second slag outlet channel connected to the recovery chamber, and the second slag outlet channel corresponds to the second filter plate. The second filter plate is inclined, and an end of the second filter plate away from the second slag outlet channel is higher than an end of the second filter plate close to the second slag outlet channel.

[0022] By adopting the above technical solution, the first filter plate filters the larger welding slag, the smaller welding slag and flux pass through the first filter plate and fall on the second filter plate, the flux and welding slag move along the second filter plate toward the second slag discharge channel, the flux passes through the second filter plate and is discharged from the flux discharge channel, the welding slag is discharged from the second slag discharge channel, the flux and welding slag are screened again through the second filter plate, thereby improving the screening effect of the flux and welding slag.

[0023] Optionally, the inner wall of the recovery chamber is connected to a guide block, which is located between the first filter plate and the second filter plate. The guide block is provided with a through hole for flux and welding slag to pass through, and the size of the through hole gradually decreases towards the direction approaching the second filter plate. The outlet of the through hole is located at the end of the guide block away from the second slag discharge channel.

[0024] By adopting the above technical solution, smaller welding slag and flux pass through the first filter plate and enter the through hole, and the flux and welding slag move along the through hole toward the second filter plate. Since the outlet of the through hole is located at the end of the guide block away from the second slag discharge channel, the flux and welding slag fall on the end of the second filter plate away from the second slag discharge channel, thereby increasing the distance between the flux and welding slag and the second slag discharge channel, that is, increasing the moving path of the flux and welding slag on the second filter plate, thereby improving the screening effect of the flux and welding slag.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The reinforcing ring and the head are welded by submerged arc welding. The excess flux rolls down along the outer arc surface of the head. The flux enters the annular channel from the opening channel.

[0027] 2. The flux and welding slag fall on the first filter plate away from the first slag discharge channel, which increases the distance between the flux and welding slag and the first slag discharge channel, that is, increases the moving path of the flux and welding slag on the first filter plate, and improves the screening effect of the flux and welding slag.
