Description

Technical Field

[0001] This invention relates to the field of welding tank technology, specifically to a novel environmentally friendly and long-life welding slag tank. Background Technology

[0002] Traditional cast slag pots are formed in one piece through casting. Their advantages are simple structure and potentially low initial cost. Their disadvantages are heavy weight and susceptibility to casting defects. Long-life slag pots, on the other hand, are based on cast slag pots with optimized structures that enhance their stress resistance.

[0003] In the prior art, such as the novel environmentally friendly long-life welded slag tank with application number CN105296692A, there is a cylinder and a bottom plate. The bottom of the cylinder is connected to the bottom plate through a circumferential weld. The cylinder is welded from low alloy high-strength heat-treated rolled steel plate. Multiple circumferential stiffeners are provided on the outer side of the cylinder, and multiple vertical stiffeners are provided between the circumferential stiffeners.

[0004] By coordinating vertical and circumferential reinforcing ribs, the outer surface of the tank is reinforced in multiple directions. However, in this technical solution, the pouring of slag can easily cause great thermal pressure on the inner wall of the slag tank. The fixed reinforcing ribs have limited support area and cannot cope with the thermal pressure. Therefore, it is necessary to slide the reinforcing ribs to expand the thermal support area and prevent the slag tank from developing excessive cracks. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a novel environmentally friendly and long-life welded slag pot that effectively solves the problem that the fixed reinforcing ribs in existing technologies have limited support area and cannot cope with the thermal pressure of flow.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a novel environmentally friendly, long-life welded slag pot, comprising a base, a control panel and a support frame fixedly connected to the upper surface of the base, a matching straight shaft fixedly connected to one side of the two support frames that are close to each other, a slag pot rotatably connected to one side of the matching straight shaft, reinforcing ribs fixedly connected to the outer surface of the slag pot, an arc-shaped top plate slidably connected to the outer surface of the reinforcing ribs, a circulating stress relief assembly provided with the arc-shaped top plate, the circulating stress relief assembly including a docking body fixedly connected to the outer side of the arc-shaped top plate, a matching column movably inserted into one side of the docking body, an L-shaped frame fixedly connected to the end face of the matching column, a pushing member cooperating with the L-shaped frame, the pushing member providing displacement driving force for the L-shaped frame.

[0007] Furthermore, the pusher includes a rack fixedly connected to the bottom of the L-shaped frame. The bottom of the rack slides in engagement with the base. A drive source is fixedly installed on the upper surface of the base. A plug shaft is fixedly connected to the output end of the drive source. A ring gear is fixedly sleeved on the outer surface of the plug shaft. The plug shaft is fixedly placed on the top of the base through a bearing seat. The teeth of the ring gear mesh with the rack.

[0008] Furthermore, an extension arm is fixedly connected to the side of the ring gear. A receiving plate is hinged to the extension arm via an ear plate provided at the top. The end face of the receiving plate mates with the open end face of the slag pot. The receiving plate is used to receive welding slag. A tension spring assembly is fixedly installed at the bottom of the receiving plate. The tension spring assembly is fixed to the top of the base via a bolt seat at the bottom. The tension spring assembly is used to stabilize the positional jitter caused by the hinged movement of the end face of the receiving plate.

[0009] Furthermore, the signal output terminal of the control panel is electrically connected to the adapter straight shaft, which can help the slag pot continuously pour out welding slag.

[0010] Furthermore, there are several reinforcing ribs and arc-shaped top plates, which are arranged in a ring. The L-shaped frame is equipped with a swing cooling assembly. The swing cooling assembly includes an extension frame fixedly connected to the outer side of the L-shaped frame. An arc-shaped toothed disc is fitted to the top of the extension frame. The teeth of the arc-shaped toothed disc mesh with a fan-shaped plate. A support column is rotatably connected to the apex of the fan-shaped plate. A conical nozzle is fitted onto the upper surface of the fan-shaped plate. A middle nozzle is placed on the side of the conical nozzle.

[0011] Furthermore, the arc-shaped surface of the arc-shaped top plate fits into the circular surface of the slag pot. This arrangement helps the internal thermal stress of the slag pot to be absorbed in time when pouring welding slag, thus preventing local cracks from appearing in the slag pot.

[0012] Furthermore, the L-shaped frame is also equipped with a cooling and stress-resistant component. The cooling and stress-resistant component includes a receiving frame fixedly installed on the side of the L-shaped frame. A guide arc surface seat is movably inserted into one side of the receiving frame. The guide arc surface seat cooperates with the receiving plate and is used for secondary transportation of welding slag. A fan is connected to the top of the receiving frame. The fan is used to cool the welding slag and cool the receiving plate, so that a temperature difference is generated at the position of the receiving plate near the end face of the slag pot. This can reduce the risk of bottom cracking when the welding slag is poured out of the slag pot. The fan is also connected to the conical nozzle and the intermediate nozzle.

[0013] Furthermore, the top of the blower is connected to a telescopic pipe, and an ejector is fitted to the end face of the telescopic pipe. The open end face of the ejector is fitted with the inner wall of the slag pot and is used for direct cooling of the slag pot.

[0014] Furthermore, the outer surface of the telescopic tube is connected to an inner layer via a branch pipe. The inner layer is fitted and connected to the inner surface of the slag pot, and the inner layer is used to relieve thermal stress on the inner wall of the slag pot.

[0015] Furthermore, the inner surface of the built-in layer is provided with a pillow block, which is used to prevent some welding slag from accumulating and remaining inside the slag pot.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By adapting the straight shaft and rotating the slag pot, the slag pot can be rotated to pour out the welding slag, which helps to reduce the stress caused by the large amount of welding slag. In addition, through the L-shaped frame and the adapter column, the cooperation between the docking body and the arc-shaped top plate allows the displacement force to be transferred to the arc-shaped top plate multiple times, so that the arc-shaped top plate can slide continuously along the surface of the reinforcing rib, directly expanding the area for absorbing thermal stress and providing more comprehensive support and protection for the slag pot, avoiding the problem of continuous cracks in the slag pot when pouring out welding slag. 2. As the ring gear continuously meshes, it will deflect at an angle. This deflection will transmit the rotational force to the receiving plate through the extension arm, and then cause the position of the receiving plate to change through the hinge. This allows the receiving plate to receive the welding slag in different positions. When the receiving plate moves, considering that the weight will increase due to the continuous falling of welding slag, a tension spring assembly needs to be installed at the bottom of the receiving plate to balance this weight increase. This allows the tension spring assembly to absorb the vibration caused by the increased weight when the position of the receiving plate changes, ultimately maintaining the dynamic balance of the receiving plate during the movement and ensuring the full reception of the welding slag.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] See attached document Figure 1-9 A novel environmentally friendly and long-life welded slag pot includes a base 1. A control panel 2 and a support frame 3 are fixedly connected to the upper surface of the base 1. Adaptive straight shafts 4 are fixedly connected to the two support frames 3 on their adjacent sides. A slag pot 5 is rotatably connected to one side of the adaptive straight shaft 4. A reinforcing rib 6 is fixedly connected to the outer surface of the slag pot 5. An arc-shaped top plate 61 is slidably connected to the outer surface of the reinforcing rib 6. A circulating stress relief component 7 is provided on the arc-shaped top plate 61. The circulating stress relief component 7 includes a docking body 71 fixedly connected to the outer side of the arc-shaped top plate 61. An adapter column 72 is movably inserted into one side of the docking body 71. An L-shaped frame 73 is fixedly connected to the end face of the adapter column 72. A pushing component 74 is provided to the L-shaped frame 73 to drive its displacement.

[0023] First, control panel 2 is activated. Control panel 2 controls the rotation of the adapter shaft 4. Then, supported by support frame 3, the adapter shaft 4 drives the slag pot 5 to rotate continuously. The slag pot 5 can quickly pour out welding slag. At the same time, pusher 74 is opened. Pusher 74 moves the L-shaped frame 73 in a straight line in the horizontal direction. The straight line movement of the L-shaped frame 73 will drive the adapter column 72 to move in the same direction. Then the adapter column 72 will contact and complete the insertion with the docking body 71, so that the docking body 71 and the adapter column 72 maintain a straight line movement. The sliding of the docking body 71 will drive the arc-shaped top plate 61 to slide continuously along the surface of the reinforcing rib 6, which will increase the protection and stress relief range of the arc-shaped top plate 61. As the slag pot 5 continues to pour out welding slag, the thermal stress brought by the flow of welding slag will quickly fill the entire cavity of the slag pot 5. At this time, the sliding of the arc-shaped top plate 61 will continuously absorb the thermal stress in the cavity of the slag pot 5, significantly reducing the risk of fracture and damage to the inner wall of the slag pot 5. By adapting the straight shaft 4 and rotating the slag pot 5, the slag pot 5 can rotate and pour out the welding slag, which helps to reduce the accumulated stress caused by a large amount of welding slag. In addition, through the cooperation of the L-shaped frame 73 and the adapter column 72, the mating body 71 and the arc-shaped top plate 61, the displacement force can be transferred to the arc-shaped top plate 61 multiple times, so that the arc-shaped top plate 61 can slide continuously along the surface of the reinforcing rib 6, which directly expands the area for absorbing thermal stress and provides more comprehensive support and protection for the slag pot 5, avoiding the problem of continuous cracks in the slag pot 5 when pouring out welding slag.

[0024] The pusher 74 includes a rack 741 fixedly connected to the bottom of the L-shaped frame 73. The bottom of the rack 741 is slidably engaged with the base 1. A drive source 744 is fixedly mounted on the upper surface of the base 1. A plug shaft 743 is fixedly connected to the output end of the drive source 744. A ring gear 742 is fixedly sleeved on the outer surface of the plug shaft 743. The plug shaft 743 is fixedly placed on the top of the base 1 through a bearing seat. The teeth of the ring gear 742 mesh with the rack 741.

[0025] At the same time, the drive source 744 is turned on, and the drive source 744 drives the ring gear 742 to rotate continuously through the insert shaft 743. Then, the teeth of the ring gear 742 drive the rack 741 to move horizontally through meshing. This horizontal displacement force can be used as the displacement driving force of the L-shaped frame 73, providing a linkage basis for the continuous sliding of the arc-shaped top plate 61.

[0026] An extension arm 75 is fixedly connected to the side of the ring gear 742. The extension arm 75 is hinged to a receiving plate 76 through an ear plate provided at the top. The end face of the receiving plate 76 mates with the open end face of the slag pot 5. The receiving plate 76 is used to receive welding slag. A tension spring assembly 77 is fixedly installed at the bottom of the receiving plate 76. The tension spring assembly 77 is fixed to the top of the base 1 through a bolt seat at the bottom. The tension spring assembly 77 is used to stabilize the positional jitter caused by the hinged movement of the end face of the receiving plate 76.

[0027] As the ring gear 742 continuously meshes, it will deflect at an angle. This deflection will transmit the rotational force to the receiving plate 76 through the extension arm 75. Then, the position of the receiving plate 76 will change through the hinge, so that the receiving plate 76 can receive the welding slag in different positions. When the receiving plate 76 moves, considering that the weight will increase due to the continuous falling of welding slag, in order to balance this weight increase, a tension spring assembly 77 needs to be set at the bottom of the receiving plate 76. When the position of the receiving plate 76 changes, the vibration caused by the increase in weight is absorbed by the tension spring assembly 77 in time, so that the receiving plate 76 maintains dynamic balance during the movement, ensuring the full reception of welding slag.

[0028] See attached document Figure 2 - Figure 6 It also includes: the signal output terminal of the control panel 2 is electrically connected to the adapter straight shaft 4, the adapter straight shaft 4 can help the slag pot 5 to continuously pour out welding slag, the number of reinforcing ribs 6 and arc-shaped top plate 61 is several, the several reinforcing ribs 6 and arc-shaped top plate 61 are distributed in a ring, and the L-shaped frame 73 is equipped with a swing cooling component 9, the swing cooling component 9 includes an extension frame 91 fixedly connected to the outer side of the L-shaped frame 73, the top of the extension frame 91 is fitted with an arc-shaped toothed disk 92, the teeth of the arc-shaped toothed disk 92 mesh with a fan-shaped plate 93, the top corner of the fan-shaped plate 93 is rotatably connected to a support column 94, and a conical nozzle 95 is adapted to be installed on the upper surface of the fan-shaped plate 93, and an intermediate nozzle 96 is placed on the side of the conical nozzle 95.

[0029] After the personnel arrive at the position, they need to operate the control panel 2 to send a signal to the adapter shaft 4, so that the adapter shaft 4 has the ability to rotate continuously. The several reinforcing ribs 6 and the arc-shaped top plate 61 set on the outer surface of the slag pot 5 can provide a solid support effect for the outer surface of the slag pot 5, preventing excessive thermal stress caused by the pouring of welding slag. When the L-shaped frame 73 moves, it will drive the extension frame 91 to move synchronously, and allow the arc-shaped toothed disc 92 set on the top to mesh with the sector plate 93, so that the sector plate 93 and the conical nozzle 95 can swing and rotate, which will then cause the conical nozzle 95 to swing within a certain angle range, which can be used for air cooling of welding slag in the slag pot 5.

[0030] The arc-shaped surface of the arc-shaped top plate 61 fits into the circular surface of the slag pot 5. This arrangement helps the internal thermal stress of the slag pot 5 to be absorbed in time when pouring welding slag, thus preventing local cracks from appearing in the slag pot 5.

[0031] See attached document Figure 7-8It also includes: the L-shaped frame 73 is also equipped with a cooling stress-resistant component 8, which includes a receiving frame 81 fixedly installed on the side of the L-shaped frame 73. A guide arc surface seat 82 is movably inserted into one side of the receiving frame 81. The guide arc surface seat 82 cooperates with the receiving plate 76 and is used for secondary transportation of welding slag. A fan 83 is connected to the top of the receiving frame 81. The fan 83 is used to cool the welding slag, so that a temperature difference is generated at the position of the receiving plate 76 near the end face of the slag pot 5, which can reduce the risk of bottom cracking when the welding slag is poured out of the slag pot 5.

[0032] To eliminate the thermal stress at the tipping point of the slag pot 5, an additional cooling stress-resistant component 8 is required to counteract the thermal stress caused by the falling welding slag. Note that the L-shaped frame 73 is constantly shifting. This shifting motion causes the receiving frame 81 and the guide arc seat 82 to move accordingly, guiding the discharge of welding slag. At the same time, the fan 83 is activated, and the cold air ejected from the output end of the fan 83 moves irregularly. Due to the continuous tipping of welding slag at the end face of the receiving plate 76, the temperature at the end face is very high. The hot air with a lower density is located at the upper part of the end face, while the cold air ejected by the fan 83 has a higher density and is located at the lower part of the end face. The temperature difference effect causes the hot air and cold air to form convection. The cold air continuously absorbs the heat from the tipping point of the welding slag on the receiving plate 76, further creating a temperature difference between the end face and the inner wall. The heat on the inner wall of the slag pot 5 is quickly conducted to the end face and continues to participate in convection, so that the thermal stress on the inner wall of the slag pot 5 is quickly counteracted, ultimately improving the service life of the slag pot 5.

[0033] The top of the blower 83 is connected to a telescopic pipe 84. The end face of the telescopic pipe 84 is fitted with an ejector 85. The open end face of the ejector 85 is fitted with the inner wall of the slag pot 5 and is used for direct cooling of the slag pot 5. The outer surface of the telescopic pipe 84 is connected to an inner layer 86 through a branch pipe. The inner layer 86 is fitted and connected to the inner surface of the slag pot 5 and is used for thermal stress relief on the inner wall of the slag pot 5.

[0034] In order to accelerate the offsetting of thermal stress on the inner wall of the slag pot 5, a telescopic pipe 84 needs to be opened at the top of the blower 83 so that the telescopic pipe 84 can also move horizontally when the L-shaped frame 73 moves. This horizontal movement can reduce the escape of cold air from the output end of the blower 83, allowing more cold air to be transferred to the interior of the inner layer 86, which facilitates the direct cooling of the inner wall of the slag pot 5.

[0035] The inner surface of the built-in layer 86 is provided with a pillow block 87, and the cold air on the surface of the pillow block 87 is used to prevent some welding slag from accumulating inside the slag pot 5.

[0036] Working principle: First, the control panel 2 is activated. The control panel 2 controls the rotation of the adapter shaft 4. Then, under the support of the support frame 3, the adapter shaft 4 drives the slag pot 5 to rotate continuously. The slag pot 5 can quickly pour out the welding slag. At the same time, the pusher 74 is opened. The pusher 74 carries the L-shaped frame 73 to move linearly in the horizontal direction. The linear displacement of the L-shaped frame 73 will drive the adapter column 72 to move in the same direction. Then the adapter column 72 will contact the docking body 71 and complete the insertion, so that the docking body 71 and the adapter column 72 maintain a linear motion. The sliding of the docking body 71 will drive the arc-shaped top plate 61 to slide continuously along the surface of the reinforcing rib 6, which will increase the protection and stress relief range of the arc-shaped top plate 61. As the slag pot 5 continuously pours out the welding slag, the thermal stress brought by the flow of welding slag will quickly fill the entire inner cavity of the slag pot 5. At this time, the sliding of the arc-shaped top plate 61 will continuously absorb the thermal stress in the inner cavity of the slag pot 5, significantly reducing the risk of fracture and damage to the inner wall of the slag pot 5. At the same time, the drive source 744 is turned on, and the drive source 744 drives the ring gear 742 to rotate continuously through the insert shaft 743. Then, the teeth of the ring gear 742 drive the rack 741 to move horizontally through meshing. This horizontal displacement force can be used as the displacement driving force of the L-shaped frame 73, providing a linkage basis for the continuous sliding of the arc-shaped top plate 61.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
