Description

Technical Field

[0001] The invention belongs to the technical field of molten steel continuous casting, in particular to a continuous casting machine. Background Art

[0002] A continuous casting machine is a device that rapidly cools molten metal into continuous castings. It is widely used in the steel, non-ferrous metals and other industries to produce plates, wires, profiles and other products. It mainly includes melting, degassing, continuous casting operations, cooling and conveying.

[0003] In the continuous casting machine of the prior art, liquid metal is first poured into a crystallizer, which is rapidly cooled and solidified by a water-cooled copper plate in the crystallizer to form a casting billet. The billet is then pulled into a stretching machine by a chain. The stretching machine pulls the billet to rapidly stretch and cool it. Finally, the formed product is cut and taken out after being sheared by a shearing machine.

[0004] In the prior art, during the casting process, the continuous casting machine can only cast one size of ingot due to the limitation of the crystallizer. When ingots of different sizes need to be cast, the machine needs to be stopped and each crystallizer needs to be removed from the crystallizer vibration device. This process requires a long replacement time, which in turn affects the production efficiency of the ingot.

[0005] To this end, the present invention provides a continuous casting machine. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that it takes a long time to replace crystallizers of different sizes.

[0007] To solve the above-mentioned technical problems, the present invention provides a continuous casting machine, including a support frame; a hopper is installed on the top of the support frame; multiple evenly arranged discharge ports are opened at the bottom of the hopper; a base is provided on one side of the support frame; a rotating assembly is installed on the top surface of the base; a receiving seat is fixedly connected to the top surface of the rotating assembly; the rotating assembly includes a rotating shaft, which drives the receiving seat to rotate; evenly arranged vibration devices are installed around the receiving seat; the vibration devices are divided into four groups, and the vibration devices in each group are arranged in a one-to-one correspondence with the discharge ports at the bottom of the hopper; a crystallizer is fixedly connected to the end of the vibration device; the vibration device is specifically used to drive the crystallizer to vibrate; a guide frame is fixedly connected to the bottom of the crystallizer on the support frame; multiple evenly arranged rotating rollers are rotatably connected to the surface of the guide frame; a receiving frame is fixedly connected to the end of the guide frame away from the hopper; during operation, in order to ensure the efficiency of crystallizer replacement, the present invention embodiment can be used. First, the user needs to install crystallizers of various sizes required in the vibration devices around the base. To ensure that the crystallizers in each set of vibrating devices are of uniform size, when the user needs to change to a different size crystallizer, the user needs to rotate the receiving seat by rotating the shaft in the rotating assembly. The receiving seat then drives the vibrating devices around it to rotate together, rotating the set of crystallizers to be used to the bottom of the feeding hopper, so that the crystallizers are aligned with the discharge port at the bottom of the feeding hopper. Then, the user can feed the molten material into the feeding hopper, and then feed the molten raw material into the crystallizer through the discharge port at the bottom of the feeding hopper. The crystallizer then cools the molten raw material, causing the raw material to gradually solidify into a casting billet. The casting billet then enters between the pairs of rotating rollers at the guide frame, and finally, under the guidance of the rotating rollers, the casting billet enters the top surface of the receiving frame. Then, the user cuts and transfers the casting billet on the receiving frame. By rotating the receiving seat, vibrating assembly and crystallizer by rotating the shaft, the embodiment of the present invention can quickly change crystallizers of different sizes, thereby meeting the user's needs for casting casting billets of different sizes and reducing the impact of changing crystallizers of different sizes on production efficiency.

[0008] In one embodiment of the present invention, the rotating assembly also includes a rotating seat; the top surface of the rotating seat is fixedly connected to a hydraulic cylinder; the rotating shaft is fixedly connected to the telescopic end of the hydraulic cylinder; the rotating seat is rotatably connected to the top surface of the base, and the rotating seat is driven by a servo motor; the top surface of the rotating shaft is installed with an insertion block, and the insertion block is rectangular; the bottom surface of the receiving seat is fixedly connected to a docking seat at the corresponding position of the rotating shaft; the bottom surface of the docking seat is provided with a docking groove, and the docking groove is adapted to the insertion block; the side surface of the base is fixedly connected to a support cylinder, and the receiving seat and the support cylinder are fixed by bolts; during work, when the user needs to drive the receiving seat to rotate, the user needs to release the bolt fixation between the receiving seat and the support cylinder, and the hydraulic cylinder on the top surface of the rotating seat will drive the rotating shaft to rise, and the rising rotating shaft will drive the insertion block to rise until the insertion block is inserted The hydraulic cylinder drives the shaft and the insert block to descend, so that the insert block is separated from the docking groove on the bottom surface of the docking seat. At this time, the socket will be placed on the support tube again, and then the user will fix the socket to the top surface of the support tube again, and lift the docking seat and the socket by the insertion block, which can avoid the bottom surface of the socket directly rubbing against the support tube when the shaft drives the socket to rotate, resulting in wear of the socket. At the same time, the shaft is connected to the docking seat through the connecting block, which can avoid the shaft being always connected to the socket, causing the vibration device to drive the crystallizer to vibrate, and the shaft and the hydraulic cylinder will also vibrate, thereby reducing the service life of the hydraulic cylinder.

[0009] In one embodiment of the present invention, support columns are fixedly connected on both sides of the lower hopper; the support columns are slidably connected to the support frame; the top surface of the receiving seat is fixedly connected to a support ring; the side of the lower hopper close to the support ring is fixedly connected to a connecting plate; during operation, when the docking block lifts the receiving seat, the receiving seat will drive the support ring to squeeze the connecting plate, thereby driving the lower hopper and the support columns to rise, so that a fixed distance is always maintained between the receiving seat and the lower hopper, thereby avoiding the receiving seat from colliding with the lower hopper during the rising process, thereby causing damage to the lower hopper.

[0010] In one embodiment of the present invention, a plurality of evenly arranged rotation grooves are provided on the top surface of the support ring; the internal rotation of the rotation grooves is rotatably connected to rollers; during operation, when the support ring rotates, the connecting plate is in contact with the rollers, so when the connecting plate and the support ring move relative to each other, the rollers rotate in the rotation grooves, thereby reducing the friction between the connecting plate and the support ring when the two move relative to each other, thereby improving the service life of the connecting plate and the support ring.

[0011] In one embodiment of the present invention, support arms are fixedly connected on both sides of the vibration device; connecting columns are fixedly connected to the top surface of the receiving seat at corresponding positions of the support arms; the support arms are slidably connected to the connecting columns; dampers are installed on the surface of the support columns at the top and bottom of the support arms; during operation, when the vibration device drives the crystallizer to vibrate longitudinally, the vibration device will drive the support arm to vibrate longitudinally, so that the mechanical arm slides up and down on the surface of the connecting column, and the vibration device is damped by the damper, thereby reducing the influence of the vibration device on the receiving seat, thereby avoiding the receiving seat from vibrating greatly following the vibration device, which causes the bolts used to fix the receiving seat and the support tube to loosen.

[0012] In one embodiment of the present invention, a pair of limit plates are fixedly connected to the top surface of the support cylinder; the two limit plates are adapted to the receiving seat; the top surfaces of the two limit plates are fixedly connected to guide plates; the spacing at the bottom of the guide plates is smaller than the spacing at the top; during operation, when the hydraulic cylinder drives the rotating shaft to descend, the docking block on the top of the rotating shaft will also support the receiving seat to descend together. During the descent of the receiving seat, the receiving seat will move toward between the limit plates under the guidance of the guide plates, thereby limiting the position of the receiving seat, so that the crystallizer inside the vibration device can be aligned with the discharge port of the lower hopper at its top, ensuring that the raw materials can flow smoothly into the crystallizer.

[0013] In one embodiment of the present invention, a rotating rod is provided at the bottom of the insertion block; the rotating rod is fixedly connected to the top surface of the rotating shaft, and the rotating rod is rotatably connected to the insertion block; a mounting groove is opened inside the insertion block, and the mounting groove is arranged in an arc shape; a baffle is fixedly connected to the surface of the rotating rod in the mounting groove; a spring is fixedly connected between the baffle and the inner wall of the mounting groove; during operation, when the insertion block supports the receiving seat to move between the guide plate and the limit plate, if the receiving seat is not directly facing between the limit plates, during the process of the receiving seat descending, the edge of the receiving seat will be squeezed with the guide plate, thereby pushing the receiving seat to deflect, and then driving the insertion block to rotate on the surface of the rotating rod, and causing the baffle on the surface of the rotating rod to squeeze the spring in the mounting groove, so that the receiving seat is smoothly deflected and inserted between the two limit plates. When the insertion block is separated from the docking groove, the compressed spring recovers, thereby driving the limit block to recover, thereby avoiding the receiving seat being unable to be smoothly inserted between the two limit plates due to a large angular deviation between the receiving seat and the limit plate.

[0014] In one embodiment of the present invention, a connecting frame is provided on the surface of one side of the support tube close to the lower hopper; the connecting frame is located at the bottom of the crystallizer; a plurality of evenly arranged atomizing nozzles are fixedly connected to the surface of the connecting frame; the nozzles of the nozzles are all facing the crystallizer; during operation, after the molten raw material passes through the crystallizer, the raw material will form a preliminary ingot, and when the ingot passes through the fixed connecting frame, the nozzles on the surface of the connecting frame will intermittently spray coolant onto the surface of the ingot, thereby further cooling and shaping the ingot, so as to reduce the probability of deformation of the ingot surface.

[0015] In one embodiment of the present invention, a plurality of evenly arranged guide cylinders are fixedly connected to a side of the support cylinder close to the connecting frame; a side of the guide cylinder away from the connecting frame is connected to an external exhaust fan; during operation, when the nozzle sprays coolant toward the surface of the ingot, the guide cylinders on the surface of the support cylinder will intermittently suck the high-temperature steam at the connecting frame, thereby preventing the high-temperature steam from escaping and causing harm to workers working nearby, and at the same time reducing the stuffiness in the factory.

[0016] In one embodiment of the present invention, the liquid inlet pipes of the crystallizers in the same group are commonly fixedly connected to a main pipe, and an electric-controlled valve is installed inside the main pipe; the liquid outlet pipes of the crystallizers in the same group are commonly fixedly connected to a drain pipe; the bottom surface of the drain pipe is fixedly connected to a pump pipe, and the pump pipe and the drain pipe are isolated from each other; the main pipes are all fixedly connected to the pump pipe, and the pump pipe is connected to the inside of the main pipe; during operation, when it is necessary to pump coolant into a certain group of crystallizers, the user needs to use the electric-controlled valve to close the main pipes connected to other crystallizers that are not in use, and then the user can pump coolant into the pump pipe. Since the main pipes of the unused crystallizers are closed by the electric-controlled valve, the coolant pumped into the pump pipe will only enter the crystallizer in operation, and then the coolant is discharged into the drain pipe after passing through the crystallizer. The closing and opening of the main pipes of each group of crystallizers are controlled by the electric-controlled valve, so that the coolant can flow into the crystallizer in use in a concentrated manner, thereby reducing the waste of coolant.

[0017] The above technical solution of the present invention has the following advantages over the prior art: 1. The continuous casting machine described in the present invention drives the receiving seat, the vibration assembly and the crystallizer to rotate through the rotating shaft, so that the embodiment of the present invention can quickly replace crystallizers of different sizes, thereby meeting the user's needs for casting billets of different sizes and reducing the impact of replacing crystallizers of different sizes on production efficiency.

[0018] 2. The continuous casting machine described in the present invention lifts the docking seat and the socket by inserting a block, which can avoid the bottom surface of the socket being directly rubbed against the support tube when the rotating shaft drives the socket to rotate, causing wear of the socket. At the same time, the rotating shaft is connected to the docking seat through the connecting block, which can avoid the rotating shaft being always connected to the socket. When the vibration device drives the crystallizer to vibrate, the rotating shaft and the hydraulic cylinder will also vibrate, thereby reducing the service life of the hydraulic cylinder.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

The discharge ports 3 at the bottom of the hopper 2 are arranged in a one-to-one correspondence; the vibrating device 7 is fixedly connected to the end of the crystallizer 8; the vibrating device 7 is specifically used to drive the crystallizer 8 to vibrate; the support frame 1 is fixedly connected to the bottom of the crystallizer 8 with a guide frame 9; multiple evenly arranged rotating rollers 10 are rotatably connected to the surface of the guide frame 9; a receiving frame 11 is fixedly connected to the end of the guide frame 9 away from the hopper 2; during operation, in order to ensure the efficiency of crystallizer 8 replacement, the embodiment of the present invention can be used. First, the user needs to install crystallizers 8 of various sizes required in the vibrating device 7 around the base 4. To ensure that the crystallizers 8 in each set of vibrating devices 7 are of the same size, when the user needs to change to a different size crystallizer 8, the user needs to rotate the receiving seat 5 by rotating the shaft 6 in the rotating assembly. The receiving seat 5 then rotates the vibrating devices 7 around it, rotating the set of crystallizers 8 to be used to the bottom of the feeding hopper 2, so that the crystallizer 8 is aligned with the discharge port 3 at the bottom of the feeding hopper 2. Then the user can feed the molten material into the feeding hopper 2, and then feed the molten raw material into the crystallizer 8 through the discharge port 3 at the bottom of the feeding hopper 2. The crystallizer then... 8. The molten raw material is cooled, so that the raw material is gradually shaped into a billet. Then the billet enters between the pairs of rotating rollers 10 at the guide frame 9, and finally enters the top surface of the receiving frame 11 under the guidance of the rotating rollers 10. Then the user cuts and transfers the billet on the receiving frame 11. The rotating shaft 6 drives the receiving seat 5, the vibration component and the crystallizer 8 to rotate, which enables the embodiment of the present invention to quickly change the crystallizer 8 of different sizes, thereby meeting the user's needs for casting billets of different sizes and reducing the impact of changing the crystallizer 8 of different sizes on production efficiency.

[0024] Reference Figure 1 、 Figure 4 、 Figure 5 and Figure 8As shown, the rotating assembly also includes a rotating seat 17; a hydraulic cylinder 18 is fixedly connected to the top surface of the rotating seat 17; the rotating shaft 6 is fixedly connected to the telescopic end of the hydraulic cylinder 18; the rotating seat 17 is rotatably connected to the top surface of the base 4, and the rotating seat 17 is driven by a servo motor; an insertion block 19 is installed on the top surface of the rotating shaft 6, and the insertion block 19 is rectangular; a docking seat 20 is fixedly connected to the bottom surface of the receiving seat 5 at the corresponding position of the rotating shaft 6; the bottom surface of the docking seat 20 has an opening... The base 4 has a docking groove 21 that is compatible with the insertion block 19. A support cylinder 22 is fixedly connected to the side surface of the base 4, and the receiving seat 5 is fixed to the support cylinder 22 by bolts. During operation, when the user needs to drive the receiving seat 5 to rotate, the user needs to release the bolts between the receiving seat 5 and the support cylinder 22. The hydraulic cylinder 18 on the top surface of the rotating seat 17 will drive the rotating shaft 6 to rise, and the rising rotating shaft 6 will then drive the insertion block 19 to rise until the insertion block 19 is inserted into the receiving seat. The receiving seat 5 is inserted into the groove on the bottom surface of the support cylinder 22, and the receiving seat 5 is pushed away from the support cylinder 22. At this time, the rotating seat 17 drives the rotating shaft 6 to rotate, and the required crystallizer 8 is rotated to the bottom of the feeding hopper 2. Then the rotating seat 17 stops driving the rotating shaft 6 to rotate, and the hydraulic cylinder 18 drives the rotating shaft 6 and the insert block 19 to descend, so that the insert block 19 is disengaged from the docking groove 21 on the bottom surface of the docking seat 20. At this time, the receiving seat 5 will be placed back on the support cylinder 22. Then the user fixes the receiving seat 5 to the top surface of the support cylinder 22. The insert block 19 lifts the docking seat 20 and the receiving seat 5, which can avoid the bottom surface of the receiving seat 5 directly rubbing against the support cylinder 22 when the rotating shaft 6 drives the receiving seat 5 to rotate, which would cause the receiving seat 5 to wear. At the same time, the rotating shaft 6 is inserted into the docking seat 20 through the connecting block, which can avoid the rotating shaft 6 being always connected to the receiving seat 5. As a result, when the vibration device 7 drives the crystallizer 8 to vibrate, the rotating shaft 6 and the hydraulic cylinder 18 will also vibrate, which will reduce the service life of the hydraulic cylinder 18.

[0025] Reference Figures 1 to 2 As shown, support columns 12 are fixedly connected to both sides of the hopper 2; the support columns 12 are slidably connected to the support frame 1; a support ring 13 is fixedly connected to the top surface of the receiving seat 5; a connecting plate 14 is fixedly connected to the side of the hopper 2 near the support ring 13; during operation, when the connecting block lifts the receiving seat 5, the receiving seat 5 will drive the support ring 13 to squeeze the connecting plate 14, thereby driving the hopper 2 and the support columns 12 to rise, so that the receiving seat 5 and the hopper 2 always maintain a fixed distance, thereby avoiding the hopper 2 from colliding with the receiving seat 5 during the rising process, thus preventing damage to the hopper 2.

[0026] Reference Figures 1 to 3As shown, the top surface of the support ring 13 is provided with a plurality of evenly arranged rotation grooves 15; the internal rotation of the rotation grooves 15 is rotatably connected to the rollers 16; during operation, when the support ring 13 rotates, the connecting plate 14 is in contact with the rollers 16, so when the connecting plate 14 and the support ring 13 move relative to each other, the rollers 16 rotate in the rotation grooves 15, thereby reducing the friction between the connecting plate 14 and the support ring 13 when the two move relative to each other, thereby improving the service life of the connecting plate 14 and the support ring 13.

[0027] Reference Figure 1 and Figure 6 As shown, support arms 23 are fixedly connected to both sides of the vibration device 7; connecting columns 24 are fixedly connected to the top surface of the receiving seat 5 at the corresponding positions of the support arms 23; the support arms 23 are slidably connected to the connecting columns 24; dampers 25 are installed on the surface of the support column 12 at the top and bottom of the support arms 23; during operation, when the vibration device 7 drives the crystallizer 8 to vibrate longitudinally, the vibration device 7 will drive the support arm 23 to vibrate longitudinally, so that the mechanical arm slides up and down on the surface of the connecting column 24, and the vibration device 7 is damped by the damper 25, thereby reducing the influence of the vibration device 7 on the receiving seat 5, thereby avoiding the receiving seat 5 from vibrating greatly following the vibration device 7, which causes the bolts used to fix the receiving seat 5 and the support tube 22 to loosen.

In the process of the receiving seat 5 descending, the receiving seat 5 will move toward the limit plates 26 under the guidance of the guide plates 27, thereby limiting the position of the receiving seat 5, so that the crystallizer 8 inside the vibration device 7 can be aligned with the discharge port 3 of the lower hopper 2 at its top, ensuring that the raw materials can flow smoothly into the crystallizer 8.

In the process, the edge of the receiving seat 5 will be squeezed with the guide plate 27, thereby pushing the receiving seat 5 to deflect, and then driving the insertion block 19 to rotate on the surface of the rotating rod 28, and making the baffle 30 on the surface of the rotating rod 28 squeeze the spring 31 in the mounting groove 29, so that the receiving seat 5 can be smoothly deflected and inserted between the two limit plates 26. When the insertion block 19 is out of the docking groove 21, the compressed spring 31 is restored, thereby driving the limit block to recover, thereby avoiding the receiving seat 5 from being unable to be smoothly inserted between the two limit plates 26 due to the large angular deviation between the receiving seat 5 and the limit plates 26.

[0030] Reference Figure 1 and Figure 7 As shown, a connecting frame 32 is provided on the surface of one side of the support tube 22 close to the lower hopper 2; the connecting frame 32 is located at the bottom of the crystallizer 8; a plurality of evenly arranged atomizing nozzles 33 are fixedly connected to the surface of the connecting frame 32; the nozzles of the nozzles are all facing the crystallizer 8; during operation, after the molten raw material passes through the crystallizer 8, the raw material will form a preliminary ingot, and when the ingot passes through the fixed connecting frame 32, the nozzles on the surface of the connecting frame 32 will intermittently spray coolant onto the surface of the ingot, thereby further cooling and shaping the ingot, so as to reduce the probability of deformation of the ingot surface.

[0032] Reference Figure 6As shown, the liquid inlet pipes of the crystallizers 8 in the same group are commonly connected to the main pipe 35, and an electric control valve is installed inside the main pipe 35; the liquid outlet pipes of the crystallizers 8 in the same group are commonly connected to the drain pipe 36; the bottom surface of the drain pipe 36 is connected to the pump pipe 37, and the pump pipe 37 and the drain pipe 36 are isolated from each other; the main pipes 35 are all connected to the pump pipe 37, and the pump pipe 37 is connected to the inside of the main pipe 35; when working, when it is necessary to pump coolant into a certain group of crystallizers 8, the user needs to close the electric control valve. Close the main pipe 35 connected to other crystallizers 8 that are not in use, and then the user can pump cooling liquid into the pump pipe 37. Since the main pipe 35 of the unused crystallizer 8 is closed by the electric control valve, the coolant pumped into the pump pipe 37 will only enter the crystallizer 8 that is in operation, and then the coolant passes through the crystallizer 8 and is discharged into the discharge pipe. The closing and opening of the main pipe 35 of each group of crystallizers 8 is controlled by the electric control valve, so that the coolant can flow into the crystallizer 8 in use, thereby reducing the waste of coolant.

[0033] During operation, in order to ensure the replacement efficiency of the crystallizer 8, the embodiment of the present invention can be used. First, the user needs to install the crystallizers 8 of various sizes required by the user in the vibration devices 7 around the base 4, and at the same time ensure that the crystallizers 8 in each group of vibration devices 7 are of uniform size. When the user needs to replace the crystallizers 8 of different sizes, the user needs to drive the receiving seat 5 to rotate by the rotating shaft 6 in the rotating assembly, and then the receiving seat 5 drives the vibration devices 7 around it to rotate together, and rotate the group of crystallizers 8 to be used to the bottom of the lower hopper 2, so that the crystallizer 8 is aligned with the discharge port 3 at the bottom of the lower hopper 2, and then the user can introduce the molten material into the lower hopper 2, and then The molten raw material is introduced into the crystallizer 8 through the discharge port 3 at the bottom of the lower hopper 2, and then the crystallizer 8 cools the molten raw material so that the raw material is gradually shaped into a billet, and then the billet enters between the paired rotating rollers 10 at the guide frame 9, and finally, under the guidance of the rotating rollers 10, the billet finally enters the top surface of the receiving frame 11, and then the user cuts and transfers the billet on the receiving frame 11, and drives the receiving seat 5, the vibration assembly and the crystallizer 8 to rotate through the rotating shaft 6, so that the embodiment of the present invention can quickly replace crystallizers 8 of different sizes, thereby meeting the user's needs for casting billets of different sizes and reducing the impact of replacing crystallizers 8 of different sizes on production efficiency.

[0034] When the user needs to drive the receiving seat 5 to rotate, the user needs to release the bolts between the receiving seat 5 and the support cylinder 22. The hydraulic cylinder 18 on the top surface of the rotating seat 17 will drive the rotating shaft 6 to rise, and the rising rotating shaft 6 will drive the insertion block 19 to rise until the insertion block 19 is inserted into the insertion groove on the bottom surface of the receiving seat 5 and push the receiving seat 5 away from the support cylinder 22. At this time, the rotating seat 17 drives the rotating shaft 6 to rotate again, and rotates the required crystallizer 8 to the bottom of the lower hopper 2. Then the rotating seat 17 stops driving the rotating shaft 6 to rotate, and the hydraulic cylinder 18 drives the rotating shaft 6 and the insertion block 19 to descend, so that the insertion block 19 is separated from the docking seat 20. The docking groove 21 on the bottom surface, at this time the socket 5 will be placed on the support tube 22 again, and then the user will fix the socket 5 to the top surface of the support tube 22, and lift the docking seat 20 and the socket 5 through the insertion block 19, which can avoid the bottom surface of the socket 5 directly rubbing against the support tube 22 when the rotating shaft 6 drives the socket 5 to rotate, causing wear of the socket 5. At the same time, the rotating shaft 6 is connected to the docking seat 20 through the connecting block, which can avoid the rotating shaft 6 being always connected to the socket 5, causing the vibration device 7 to drive the crystallizer 8 to vibrate, and the rotating shaft 6 and the hydraulic cylinder 18 will also vibrate, thereby reducing the service life of the hydraulic cylinder 18.

[0035] When the connecting block lifts the receiving seat 5, the receiving seat 5 will drive the support ring 13 to squeeze the connecting plate 14, thereby driving the hopper 2 and the support column 12 to rise, so that the receiving seat 5 and the hopper 2 always maintain a fixed distance, thus avoiding the receiving seat 5 from colliding with the hopper 2 during the rising process, thereby causing damage to the hopper 2.

[0036] When the support ring 13 rotates, the connecting plate 14 contacts the roller 16. Therefore, when the connecting plate 14 and the support ring 13 move relative to each other, the roller 16 will rotate in the rotating groove 15, thereby reducing the friction between the connecting plate 14 and the support ring 13 when they move relative to each other, thus improving the service life of the connecting plate 14 and the support ring 13.

[0037] When the vibration device 7 drives the crystallizer 8 to vibrate longitudinally, the vibration device 7 will drive the support arm 23 to vibrate longitudinally, so that the robotic arm slides up and down on the surface of the connecting column 24, and the vibration device 7 is damped by the damper 25, thereby reducing the impact of the vibration device 7 on the receiving seat 5, thereby preventing the receiving seat 5 from vibrating significantly following the vibration device 7, which will cause the bolts used to fix the receiving seat 5 and the support tube 22 to loosen.

[0038] When the hydraulic cylinder 18 drives the rotating shaft 6 to descend, the docking block on the top of the rotating shaft 6 will also support the receiving seat 5 to descend together. During the descent of the receiving seat 5, the receiving seat 5 will move toward between the limit plates 26 under the guidance of the guide plate 27, thereby limiting the position of the receiving seat 5, so that the crystallizer 8 inside the vibration device 7 can be aligned with the discharge port 3 of the lower hopper 2 at its top, ensuring that the raw materials can flow smoothly into the crystallizer 8.

[0039] When the insertion block 19 supports the receiving seat 5 and moves toward between the guide plate 27 and the limit plate 26, if the receiving seat 5 is not directly facing the limit plate 26, during the process of the receiving seat 5 descending, the edge of the receiving seat 5 will be squeezed with the guide plate 27, thereby pushing the receiving seat 5 to deflect, and then driving the insertion block 19 to rotate on the surface of the rotating rod 28, and making the baffle 30 on the surface of the rotating rod 28 squeeze the spring 31 in the mounting groove 29, so that the receiving seat 5 can be smoothly deflected and inserted between the two limit plates 26. When the insertion block 19 disengages from the docking groove 21, the compressed spring 31 recovers, thereby driving the limit block to recover, thereby avoiding the receiving seat 5 from being unable to be smoothly inserted between the two limit plates 26 due to the large angular deviation between it and the limit plate 26.

[0040] When the molten raw material passes through the crystallizer 8, the raw material will form a preliminary ingot. When the ingot passes through the connecting frame 32, the nozzle on the surface of the connecting frame 32 will intermittently spray coolant onto the surface of the ingot, thereby further cooling and shaping the ingot to reduce the probability of deformation of the ingot surface.

[0041] When the nozzle sprays coolant toward the surface of the ingot, the guide tube 34 on the surface of the support tube 22 will intermittently draw high-temperature steam from the connecting frame 32, thereby preventing high-temperature steam from escaping and causing harm to workers working nearby, and also reducing the stuffiness in the factory.

[0042] When it is necessary to pump coolant into a certain group of crystallizers 8, the user needs to close the main pipe 35 connected to other crystallizers 8 that are not in use through the electric control valve, and then the user can pump coolant into the pump pipe 37. Since the main pipe 35 of the unused crystallizer 8 is closed by the electric control valve, the coolant pumped into the pump pipe 37 will only enter the crystallizer 8 that is in operation, and then the coolant will be discharged into the discharge pipe after passing through the crystallizer 8. The closing and opening of the main pipe 35 of each group of crystallizers 8 is controlled by the electric control valve, so that the coolant can flow into the crystallizer 8 in use, thereby reducing the waste of coolant.
