Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnace equipment, in particular to a flow blocking device provided with a guiding and pressing mechanism. Background Art

[0002] In the metal smelting industry, the melting furnace is an important equipment in the metal material processing process. When the metal changes from solid to liquid in the furnace, the liquid metal needs to flow into the flow channel through the flow eye brick and flow to the designated position through the flow channel. In the past, the metal smelting industry mostly used manual flow blocking. However, due to the limitations of operation and the influence of human factors, the brazing rod and the flow eye used for blocking are not easy to align, which easily leads to leakage of aluminum liquid.

[0003] With the development of technology, some automatic flow blocking devices have also appeared in the prior art. For example, a furnace eye blocking mechanism is disclosed in the patent with authorization announcement number CN218495837U, and its eye blocking components include a controller, a base, a cross bar, multiple fixed rods, multiple connecting rods and other structures. The mechanism ensures that the plug is pressed against the flow eye through the self-locking formed when the second connecting rod and the third connecting rod are in a straight line. However, when the second connecting rod and the third connecting rod are in a straight line, they are easily affected by external forces and lose their self-locking function. After the mechanism is used for a long time, the positions of the fixed rods, connecting rods and other components are prone to move, which leads to the misalignment of the plug and the flow eye.

[0004] Another example is the patent with the authorization announcement number CN212962838U, which also discloses a smelting furnace eyelet brick outlet plugging mechanism. When the mechanism is working, if the plug seal leaks, after the control system receives the abnormal alarm of leakage at the eyelet brick outlet, it will start the drive motor again to drive the plug to continue to move forward, and compress the corrugated protrusion behind the plug, shorten the length of the plug sleeve, and the side wall of the plug sleeve contacts and seals with the eyelet brick outlet to achieve the second sealing layer, ensure the sealing of the eyelet brick outlet, and keep the working process of the smelting furnace safe. However, the mechanism needs to be equipped with front and rear drive mechanisms, upper and lower drive mechanisms and other mechanisms. The above mechanisms specifically include drive motors, first screws, second screws, guide rods, linear guides, sliders and other components. In addition, the mechanism also needs to process and install the corrugated protrusions behind the plug, so its overall structure is relatively complex and the production cost is relatively high.

[0005] For another example, a patent with the authorization announcement number CN211782777U discloses an automatic mechanical locking device for fixing the water outlet of the flow eye brick of a molten aluminum furnace. This device is provided with a track on the flow trough. The mounting frame is slidably connected to the track through track pulleys. The cylinder shaft of the telescopic oil cylinder is fixedly connected to the mounting frame and drives the mounting frame to move horizontally on the flow trough. The propulsion mechanism is fixedly connected to the mounting frame, and the free end of the propulsion mechanism is fixedly connected to the plug. The plug is coaxially arranged with the water outlet of the flow eye brick. This device mainly drives the plug to achieve compression through the propulsion mechanism. However, this mechanism is horizontally arranged and is located on the flow channel trough, and the high-temperature molten metal liquid in the flow channel trough is likely to affect this mechanism.

A rotatable plate is provided at the front end of the lower guiding groove, and the pressing component is provided on the rotatable plate.

[0009] The upper frame body of the guiding frame includes two upper support beams, and the upper guiding groove is formed between the two upper support beams. The free ends of the two upper support beams are connected through a limit connecting plate.

[0010] An upper limit beam is provided in the upper guiding groove.

[0011] The lower frame body of the guiding frame includes two lower support beams, and the lower guiding groove is formed between the two lower support beams. A first support is provided at the free end of one of the lower support beams, and a second support is provided at the free end of the other lower support beam.

[0012] A lower limit beam is provided in the lower guiding groove.

[0013] The pressing assembly includes a pressing drive device, a pressing screw rod, and a pressing block. A screw sleeve is provided on the rotating plate, and the pressing screw rod passes through the screw sleeve.

[0014] The rotary swing arm is triangular in shape and is driven to swing by a swing arm drive device. One end of the upper side of the rotary swing arm is provided with a hinge block, and the other end is provided with a hinge shaft. The end of the power shaft of the swing arm drive device is provided with a hinge joint. A lower mounting seat is provided on the outer wall of the smelting furnace, and a bearing seat is provided on the lower mounting seat. The hinge block is hinged to the hinge joint, and both ends of the hinge shaft are respectively installed on the corresponding bearing seats.

[0015] An upper mounting seat is provided on the outer wall of the smelting furnace, and a hinge seat is provided on the upper mounting seat. The rear end of the swing arm drive device is rotatably mounted on the hinge seat.

[0017] A plug connecting frame is provided at the lower end of the rotary swing arm, and the plug rod at the rear end of the plug is connected to the plug connecting frame.

[0018] The advantages and positive effects of the present utility model are as follows:

[0019] 1. The present utility model uses a guiding frame to realize the swing guiding of the rotary swing arm, and further realizes the swing guiding of the plug at the lower end of the rotary swing arm to ensure the accurate position of the plug. An upper guiding groove is provided on the upper frame body of the guiding frame, and a lower guiding groove is provided on the lower frame body.

[0020] 2. The present utility model is provided with a pressing assembly at the front end of the lower frame body of the guiding frame. After the rotary swing arm swings downward to drive the plug to block the runner hole, the pressing assembly can press the rotary swing arm to ensure reliable blocking. And when the swing arm drive device fails, due to the limitation of the pressing assembly, the plug at the lower end of the rotary swing arm can still firmly block the runner hole on the runner brick without loosening. When the rotary swing arm needs to swing upward to drive the plug to open, the pressing assembly can drive the upper swing to open through the rotating plate at the front end of the lower frame body, so as not to affect the free entry and exit of the rotary swing arm into and out of the lower guiding groove on the lower frame body.

[0021] 3. The swing arm of the present utility model is triangular in shape to ensure the stability of the overall structure. At the same time, the self-weight of the swing arm can also increase the stability during flow blockage, so there is no need to configure additional counterweights. In addition, the swing arm driving device of the present utility model is arranged above and away from the flow channel groove, so it is less affected by high-temperature liquid metal.

[0022] 4. The present utility model integrates the guide frame and the pressing component into one, with a compact overall structure and convenient production and processing. At the same time, the guide frame and the pressing component can be integrally installed on the wall of the melting furnace, which is also convenient for on-site transformation.

[0030] As Figures 1 to 5As shown, the utility model includes a rotary swing arm 2 and a guide clamping mechanism, wherein the lower end of the rotary swing arm 2 is provided with a plug 5, the guide clamping mechanism includes a guide frame 3 and a clamping assembly 4, the guide frame 3 includes an upper frame body 301 and a lower frame body 303, and the upper frame body 301 is provided with an upper guide groove 302 for the rotary swing arm 2 to pass through, the lower frame body 303 is provided with a lower guide groove 304 for the rotary swing arm 2 to pass through, the front end of the lower guide groove 304 is provided with an openable rotating plate 403, and the clamping assembly 4 is arranged on the rotating plate 403, as shown in FIG. Figure 4 As shown, when the swivel arm 2 drives the plug 5 to swing upward and is in an open state, the rotating plate 403 also drives the clamping assembly 4 to swing upward and is in an open state. At this time, the swivel arm 2 can freely enter and exit the lower guide groove 304, but the swivel arm 2 still swings along the upper guide groove 302 to ensure accurate position. When the eyelet brick 6 needs to be blocked, as shown in FIG. Figure 3 As shown, the swivel arm 2 first falls along the lower guide groove 304 so that the plug 5 at its lower end is inserted into the flow eye on the flow eye brick 6, and then the rotating plate 403 rotates downward and drives the clamping assembly 4 to rotate to the rear side of the swivel arm 2, and then the operator controls the clamping assembly 4 to clamp the swivel arm 2, and at the same time, the plug 5 is also clamped to ensure a secure seal.

[0031] like Figure 5 As shown, in this embodiment, the upper frame body 301 of the guide frame 3 includes two upper support beams, and an upper guide groove 302 for the rotating swing arm 2 to pass through is formed between the two upper support beams, and the free ends of the two upper support beams are connected by a limiting connecting plate 3012 to prevent the rotating swing arm 2 from escaping from the upper guide groove 302.

[0032] like Figure 5 As shown, in this embodiment, an upper mounting plate 3011 is provided at one end of the upper frame 301 away from the limiting connecting plate 3012 for fixation. In addition, an upper limit beam 3013 can be provided at a suitable position in the upper guide groove 302 to limit the swing displacement of the rotary swing arm 2.

When the utility model is used, the operator can lift and open the rotating plate 403 after pulling out the rotating plate locking pin 406, so thatFigure 4 As shown, the rotary swing arm 2 can freely enter and exit the lower guide groove 304 without being affected by the pressing assembly 4.

[0034] As Figure 5 shown, in this embodiment, a lower mounting plate 3031 is provided at one end of the lower frame body 303 away from the rotating plate 403 for fixation. In addition, a lower limiting beam 3034 can be arranged at a suitable position in the lower guide groove 304 to limit the swinging displacement of the rotary swing arm 2.

[0035] As Figures 1 to 3 shown, in this embodiment, the pressing assembly 4 includes a pressing drive device 402, a pressing screw 404 and a pressing block 401. A screw sleeve is provided on the rotating plate 403, and the pressing screw 404 passes through the screw sleeve. The front end of the pressing screw 404 is connected to the pressing block 401, and the rear end is connected to the pressing drive device 402. When the utility model is in use, the pressing screw 404 is driven to rotate by the pressing drive device 402 to achieve movement, and then drive the pressing block 401 to move to press the rotary swing arm 2. The pressing drive device 402 can select a suitable component according to actual needs. For example, if a manual method is adopted, as Figure 2 shown, a handwheel can be used to drive the pressing screw 404 to rotate to achieve movement. If an automatic method is adopted, a micro reduction motor or the like can be used to drive the pressing screw 404 to rotate to achieve movement.

[0036] As Figure 1 and Figures 3 to 4 shown, in this embodiment, the rotary swing arm 2 is driven to swing by a swing drive device 1. In addition, an upper mounting seat 7 and a lower mounting seat 9 are provided on the outer wall 8 of the melting furnace. An articulated seat 701 is provided on the upper mounting seat 7, and the rear end of the swing drive device 1 is rotatably mounted on the articulated seat 701. The rotary swing arm 2 is triangular to ensure the stability of the overall structure. A plug connection frame 201 is provided at the lower end of the rotary swing arm 2, and the plug rod at the rear end of the plug 5 is connected to the plug connection frame 201. An articulated block 203 is provided at one end on the upper side of the rotary swing arm 2, and an articulated shaft 202 is provided at the other end. A hinge head 101 is provided at the end of the power shaft of the swing drive device 1 and is articulated with the articulated block 203. A bearing seat 901 is provided on the lower mounting seat 9, and both ends of the articulated shaft 202 are respectively mounted on the corresponding bearing seats 901. The swing drive device 1 can adopt a device such as a cylinder according to actual needs.

[0037] As Figure 1 and Figures 3 to 5As shown, the upper mounting plate 3011 at the rear end of the upper body 301 of the guiding frame 3 and the lower mounting plate 3031 at the rear end of the lower body 303 are both mounted on the lower mounting base 9. The two upper support beams of the upper body 301 are respectively connected to the corresponding lower support beams on the lower body 303 through the vertical frames 305 on the corresponding sides to ensure stable support.

[0038] The working principle of the present utility model is as follows:

[0039] When the present utility model is working, when the flow eye on the flow eye brick 6 is opened, as Figure 4 shown, the rotating plate 403 first drives the pressing assembly 4 to rotate upwards to the open state. Then, the rotary swing arm 2 is driven by the swing arm driving device 1 to drive the plug 5 to swing upwards and open. However, at the same time, the rotary swing arm 2 still swings along the upper guiding groove 302 to ensure accurate positioning. When it is necessary to block the flow eye brick 6, as Figure 3 shown, the rotary swing arm 2 is driven by the swing arm driving device 1 to first fall along the lower guiding groove 304 and make the plug 5 at its lower end insert into the flow eye on the flow eye brick 6. Then, the rotating plate falls and drives the pressing assembly 4 to move to the rear side of the rotary swing arm 2. Then, the operator controls the pressing assembly 4 to press the rotary swing arm 2, and at the same time, that is, to press the plug 5 to ensure reliable sealing. In addition, if the swing arm driving device 1 fails, due to the limitation of the pressing assembly 4, the plug 5 at the lower end of the rotary swing arm 2 can still firmly block the flow eye on the flow eye brick 6, and at this time, the repair and replacement of the swing arm driving device 1 can be carried out.

[0040] The rotary swing arm 2 of the present utility model is triangular in shape to ensure the stability of the overall structure. At the same time, the self-weight of the swing arm can also increase the stability during flow blocking, so there is no need to additionally configure a counterweight block. At the same time, the swing arm driving device 1 is arranged above and far away from the flow channel groove, so it is less affected by high-temperature liquid metal.
