Description

A vermiculite covering agent feeding device TECHNICAL FIELD

[0001] The present application relates to the technical field of general equipment manufacturing, in particular to a vermiculite covering agent feeding device. BACKGROUND

[0002] Vermiculite belongs to metallurgical process auxiliary materials, and is used for heat preservation when molten steel is cast at present, so that the molten steel in the ladle cools slowly and the ingot cools slowly in the continuous casting process. The method is to put wood ash, fly ash and carbonized rice husk on the surface of the molten steel after the molten steel flows into the ladle and on the ingot in the continuous casting process as a covering heat preservation;

[0003] The patent application with publication number CN213264732U relates to the technical field of general equipment manufacturing, and comprises a quantitative machine and a feed hopper installed on the upper end of the quantitative machine, and further comprises a conveying mechanism for conveying the covering agent discharged by the quantitative machine to one side of the ladle in a quantitative and divided manner, wherein the conveying mechanism is made of metal to cope with the temperature of the iron liquid in the ladle. After the amount of covering agent is determined, the chain plate machine moves, the quantitative machine adds the covering agent into the feeding box, and then under the movement of the chain plate, the covering agent is sent to the discharge box at the end to complete the feeding. Here, the chain plate machine is made of metal and can withstand the temperature of the ladle, and at the same time, the quantitative machine is pulled away from the ladle to protect the quantitative machine and increase the service life. The discharge pipe facilitates discharging and avoids spilling of the covering agent.

[0004] When vermiculite is used to cover the surface of the molten steel in the ladle and the ingot for heat preservation, it is directly poured onto the molten steel, which is easy to form a small hill on the molten steel, resulting in uneven heat preservation effect of the molten steel. Moreover, directly pouring vermiculite on the center will cause a large impact force, which will cause part of the vermiculite to be wrapped into the molten steel due to the impact on the surface of the molten steel, affecting the quality of the molten steel itself. In addition, the traditional covering agent has poor heat preservation effect, and dust flies during use, which deteriorates the casting environment and is harmful to the health of workers.

[0015] Preferably, the inner wall of the internally threaded sleeve is threadedly connected with a threaded rod, one end of the threaded rod is fixedly connected with a circular rod, the two ends of the circular rod are fixedly connected with the inner wall of the sliding cover, and the circular rod penetrates through the circular cover A and the circular cover B and is fixedly connected with the circular cover A and the circular cover B.

[0016] Preferably, the inner wall of the circular rod is slidably connected with a sliding arc-shaped plate, the sliding arc-shaped plate is an arc-shaped plate structure, and the sliding arc-shaped plate is in an inclined state.

[0017] Preferably, the top of the sliding arc-shaped plate is fixedly connected with a connecting block, the bottom of the connecting block is fixedly connected with an elastic rope, and one end of the elastic rope is fixedly connected with the outer wall of the circular rod.

[0018] The vermiculite covering agent feeding device has the following beneficial effects:

[0019] 1. This invention, by setting up a vermiculite feeding mechanism, allows the vermiculite originally placed on the opening and closing plate inside the sliding cover to fall naturally into the molten steel in the ladle below due to gravity, thus achieving automatic and sealed injection. This prevents a large amount of vermiculite from being scattered when poured directly, and the high-temperature air in the ladle causing some vermiculite to drift outwards, resulting in uneven vermiculite feeding and affecting the amount of vermiculite fed. The sealed method avoids the problems of hot air flow and vermiculite scattering.

[0020] 2. This invention, by setting up a vermiculite feeding mechanism, achieves corresponding amounts of vermiculite falling at corresponding positions, preventing a large amount of vermiculite from falling all from the middle position and causing small hill-like accumulation on the molten steel, resulting in uneven heat preservation. By dropping vermiculite in layers, the vermiculite is evenly distributed on the molten steel, making the thickness of the vermiculite covering the molten steel as uniform as possible, thus ensuring a stable heat preservation effect on the molten steel with limited vermiculite and accumulation amount.

[0021] 3. This invention sets up a vermiculite feeding mechanism and pours vermiculite in by opening and closing two plates, which achieves rapid and quantitative injection of a large amount of vermiculite. This avoids the problems that occur when pouring vermiculite by tilting, where the pouring speed is too fast and leakage is easy, while too slow pouring affects efficiency.

[0022] 4. By setting up a vermiculite feeding mechanism, the vermiculite in the central part will not pile up into small hills due to the limited size of the circular cover A and circular cover B. Instead, more vermiculite will be evenly sprinkled onto the molten steel in the ladle through the gap between the circular cover B and the sliding cover as the opening and closing plate rotates. This makes the molten steel coverage more uniform, further improves the heat preservation effect, and avoids heat loss.

[0023] 5. By setting up a vermiculite feeding mechanism, the outer ring of the vermiculite pile that is sprinkled onto the molten steel through the opening and closing plate is fully leveled, effectively preventing the problem of the outer layer being sprinkled and piled up too high during centrifugal rotation, and leveling the pile itself to achieve the function of flattening the vermiculite pile.

[0044] In use, through inlet cover 5 to fill the vermiculite in lifting sleeve 301, then start electric mechanical arm 1, push lifting sleeve 301 down, make the annular groove of sliding cover 302 bottom set in the ladle top, through the way of inserting annular groove on the ladle top, mutually buckle, and along with the continuous descent of electric mechanical arm 1, push sliding cover 302 is not moved by the ladle, then when electric mechanical arm 1 and lifting sleeve 301 continue to descend, lifting sleeve 301 inner wall is slidably descended on the outer wall of sliding cover 302, and through bearing 303 drive hinge rod 304 synchronous descent, hinge rod 304 descent then push connecting plate 305, connecting plate 305 is slid on support plate 307 through slide 306, and through two connecting plates 305 pull two corresponding opening and closing plates 309, so that two opening and closing plates 309 are pulled out, after opening and closing plates 309 are pulled out to both sides, the vermiculite originally placed in the sliding cover 302 in opening and closing plates 309, then will fall along with gravity, naturally fall in the molten steel of the lower ladle, realize automatic injection of closed type, prevent a large number of vermiculite from being scattered when directly pouring, and the high temperature air in the ladle is blown back to the outside, so that the uniformity of vermiculite input and the input amount are affected, the closed mode avoids the problem of flowing and vermiculite scattering when hot air rises;

[0045] Example two:

[0046] Please refer to FIG. 1-12, on the basis of example one, the present application provides a technical solution: hinge rod 304 one end is hinged with connecting plate 305, connecting plate 305 bottom is fixedly connected with slide 306, connecting plate 305 one side is fixedly connected with opening and closing plate 309.

[0047] Opening and closing plate 309 is two, opening and closing plate 309 bottom and slide 306 top fixed connection, slide 306 bottom is slidably connected with support plate 307, support plate 307 outer wall and sliding cover 302 outer wall fixed connection.

[0048] The outer wall of the sliding cover 302 is provided with a sliding groove 308, the outer wall of the opening and closing plate 309 is in sliding connection with the inner wall of the sliding groove 308, the inner wall of the sliding cover 302 is provided with a circular cover A 310 and a circular cover B 311, and the centers of the circular cover A 310 and the circular cover B 311 are the same.

[0049] When the opening and closing plate 309 is opened to both sides, the vermiculite falls from different layers of the circular cover A 310, the circular cover B 311 and the inner wall of the sliding cover 302, so that when the opening and closing plate 309 is quickly opened outward, the vermiculite will first fall from the circular cover A 310, then continue to fall between the circular cover A 310 and the circular cover B 311, and finally fall between the circular cover B 311 and the sliding cover 302, so as to realize the corresponding falling amount of vermiculite at the corresponding position, prevent a large amount of vermiculite from falling from the middle position, and cause the final small hill-shaped vermiculite to accumulate on the molten steel, resulting in uneven heat preservation effect. Through the layered falling of vermiculite, the vermiculite is evenly distributed on the molten steel, the thickness of the vermiculite covering the molten steel is as uniform as possible, and the limited amount of vermiculite and the stacking amount are ensured to ensure the stable heat preservation effect on the molten steel;

[0050] And the two opening and closing plates 309 are opened and closed to pour the vermiculite, so as to realize the rapid and quantitative injection of a large amount of vermiculite, avoid the problems of easy leakage caused by too fast pouring speed of the vermiculite and low efficiency caused by too slow pouring speed of the vermiculite when the vermiculite is poured by pouring;

[0051] Example three:

[0052] Please refer to FIGS. 1-14, on the basis of example one and example two, the present application provides a technical solution: the inner part of the lifting sleeve 301 is provided with a flattening mechanism 4, the flattening mechanism 4 includes a connecting rod 401, one end of the connecting rod 401 is fixedly connected with the inner wall of the lifting sleeve 301, and the other end of the connecting rod 401 is fixedly connected with an internally threaded sleeve 402.

[0053] The inner wall of the internally threaded sleeve 402 is threadedly connected with a threaded rod 403, one end of the threaded rod 403 is fixedly connected with a circular rod 404, the two ends of the circular rod 404 are fixedly connected with the inner wall of the sliding cover 302, and the circular rod 404 penetrates through the circular cover A 310 and the circular cover B 311 and is fixedly connected with the circular cover A 310 and the circular cover B 311.

[0054] The inner wall of the circular rod 404 is slidingly connected with a sliding arc-shaped plate 405, the sliding arc-shaped plate 405 is in an inclined state.

[0055] The sliding arc-shaped plate 405 is fixedly connected with a connecting block 406 at the top, and the connecting block 406 is fixedly connected with an elastic rope 407 at the bottom, and one end of the elastic rope 407 is fixedly connected with the outer wall of the round rod 404.

[0056] When the electric mechanical arm 1 and the lifting sleeve 301 are lowered, the inner wall of the lifting sleeve 301 drives the connecting rod 401 and the internally-threaded sleeve 402 to descend together, and when the internally-threaded sleeve 402 descends, it drives the threaded rod 403 to rotate through the thread between the inner wall and the outer wall of the threaded rod 403. The thread on the outer wall of the threaded rod 403 has an angle greater than 60 degrees and a large pitch, so when the internally-threaded sleeve 402 descends, it pushes the threaded rod 403 to rotate through the round rod 404 to drive the sliding cover 302 to rotate as a whole through the thread with small friction, and the sliding cover 302 can rotate and slide on the inner wall of the lifting sleeve 301.

[0057] When the sliding cover 302 rotates after the annular groove at the bottom of the sliding cover 302 abuts against the ladle, it can rotate relative to the upper edge of the ladle through the bearing ring on the inner wall of the sliding cover 302, so that in the process of opening the shutter 309, the straight-shaped material stack falling through the shutter 309 is effectively changed into a uniform annular shape through rotation. Since the sizes of the circular cover A 310 and the circular cover B 311 in the center part are limited, the material vermiculite in the center part will not be piled up into a hill, and more vermiculite will be evenly spread on the molten steel in the ladle through the space between the circular cover B 311 and the sliding cover 302 as the shutter 309 opens and rotates, so that the coverage of the molten steel is more uniform, the heat preservation effect is further improved, and heat loss is avoided.

[0058] When the two shutters 309 move away from each other, the sliding arc-shaped plate 405 on the inner wall of the round rod 404 is pulled down by the elastic rope 407 through the connecting block 406, and the sliding arc-shaped plate 405 is pulled down, and the sliding arc-shaped plate 405 loses the block of the shutter 309, so that it slides down below the round rod 404, and the surface of the spread vermiculite stack is rotated and stirred through the outer wall of the sliding arc-shaped plate 405 until the sliding cover 302 completely slides into the lifting sleeve 301, and the sliding cover 302 is no longer rotated. Before that, the sliding cover 302, the round rod 404 and the sliding arc-shaped plate 405 inside keep rotating, so that the outer circle position of the vermiculite stack spread on the molten steel through the shutter 309 is fully stirred and flattened, effectively preventing the problem of high outer layer spread and accumulation position during centrifugal rotation, and the material stack is flattened by itself, achieving the function of flattening the vermiculite stack.

[0059] Finally, when the vermiculite is placed, the lifting sleeve 301 and the sliding cover 302 are lifted, the sliding cover 302 falls back to the original position under the gravity, and the opening and closing plate 309 is reset, so that when the opening and closing plate 309 is reset, the sliding arc-shaped plate 405 is pushed to one side of the arc, and the sliding arc-shaped plate 405 is an inclined surface, so that the sliding arc-shaped plate 405 starts to slide upward in the inner wall of the round rod 404, and returns to the original position.

[0060] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical scheme and the inventive concept of the present application, which should be covered in the protection scope of the present application.
