Abstract
Description
Technical Field
[0001] This invention belongs to the field of smelting technology, specifically relating to an intelligent furnace-building device for a medium-frequency induction furnace used in ferro-titanium smelting. Background Technology
[0002] Smelting is a pyrometallurgical process in which metallic materials and other auxiliary materials are melted and tempered in a heating furnace, undergoing certain physical and chemical changes within the high-temperature furnace to produce crude metal or metal concentrates and slag. The smelting furnace, as an indispensable tool for smelting metals, plays a crucial role. Currently, the titanium industry mostly uses medium-frequency induction furnaces, requiring strict control of the carbon content and temperature of the furnace. The required temperature is 2000℃. Currently, smelting within the induction coil is done manually, with powders mixed according to a formula and then compacted and sintered. This compaction is typically done using manual vibrators, resulting in very high labor intensity, harsh working conditions, severe dust pollution, and poor compaction consistency. Consequently, the service life of existing manually compacted and sintered smelting furnaces is relatively short, only 60 to 80 cycles.

[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. This invention involves installing an annular material hopper at the bottom of a frame, with a discharge port at the bottom of the inner wall of the annular material hopper. An annular wing plate is installed on the outer wall of the annular material hopper, and at least two support seats arranged circumferentially along the annular wing plate are mounted on the frame.

The first motor drives the gear ring and the annular material hopper to rotate at the same time. The dry powder in the annular material hopper will be evenly spread in the annular filling space between the furnace pit and the forming mold of the smelting furnace through the discharge port, thereby achieving the purpose of automatic material spreading into the annular filling space.
[0014] 2. This invention involves installing a lifting bracket on the frame, with the lifting bracket positioned directly above the annular material hopper, and installing a rotating bracket on the lifting bracket, and a tamping plate mechanism on the rotating bracket. In actual use, since the lifting bracket is mounted on a vertical lead screw driven by a second motor, when the second motor drives the vertical lead screw to rotate, the lifting bracket can move linearly along the height direction of the vertical lead screw, simultaneously driving the rotating bracket and the tamping plate mechanism to move linearly up and down. Furthermore, by setting a sliding guide mechanism between the frame and the lifting bracket, the stability and accuracy of the lifting bracket's linear movement along the height direction of the vertical lead screw can be improved.
[0015] 3. The tamping plate mechanism of the present invention is installed on a rotating support, which is driven by a third motor. During the rotation of the rotating support, the tamping plate mechanism will rotate simultaneously with the rotating support. There are at least two tamping plate mechanisms, which are arranged at intervals along concentric circles. Each tamping plate mechanism includes a mounting frame, a vibrating motor, a preload spring, a tamping rod, and a tamping plate. In actual use, driven by the rotating support, the tamping positions of at least two tamping plates will rotate along the annular filling space. Under the vibration of the vibrating motor, the tamping rod transmits the energy of the vibrating motor to the tamping plate, thereby achieving the purpose of gradually tamping the dry material in the annular filling space using at least two tamping plates.
[0016] 4. The invention is reasonably designed, has low manufacturing cost, and is easy to promote and apply.
[0017] In summary, the present invention is reasonably designed.

[0025] Detailed Implementation
[0026] like Figure 1 , Figure 2 and Figure 3As shown, the present invention includes a frame, an annular material hopper installed at the bottom of the frame, a lifting bracket installed on the frame and located directly above the annular material hopper, a rotating bracket installed on the lifting bracket, and a tamping plate mechanism installed on the rotating bracket; a discharge port 2-1-1 is provided at the bottom of the inner sidewall 2-1 of the annular material hopper; an L-shaped bracket 5-3 is provided on the frame, and a discharge blocking plate 5-4 extending into the annular material hopper is fixedly installed on the L-shaped bracket 5-3; an annular wing plate 2-3 and a gear ring 2-4 are provided on the outer sidewall 2-2 of the annular material hopper; at least two support seats 4 are provided on the frame along the circumferential direction of the annular wing plate 2-3. The frame is equipped with a support wheel 4-1 that cooperates with the annular wing plate 2-3. The gear ring 2-4 is driven by a first motor 3. The lifting bracket is mounted on a vertical lead screw 7, which is driven by a second motor 6. A sliding guide mechanism is provided between the frame and the lifting bracket. The rotating bracket is driven by a third motor 15. The number of tamping plate mechanisms is at least two, and the at least two tamping plate mechanisms are arranged at intervals along concentric circles. The tamping plate mechanism includes a mounting frame mounted on the rotating bracket, a vibration motor 19 mounted on the mounting frame, a preload spring 20 and a tamping rod 13, and a tamping plate 14 set at the bottom end of the tamping rod 13. Multiple tamping nails 14-1 are provided on the bottom surface of the tamping plate 14.
[0027] In this embodiment, an annular material hopper is installed at the bottom of the frame. The bottom of the inner wall 2-1 of the annular material hopper has a discharge port 2-1-1. An annular wing plate 2-3 is provided on the outer wall 2-2 of the annular material hopper. At least two support seats 4 are arranged along the circumferential direction of the annular wing plate 2-3 on the frame. Support wheels 4-1 that cooperate with the annular wing plate 2-3 are provided on the support seats 4. Under the combined action of at least two support seats 4 and at least two support wheels 4-1, the bottom of the annular material hopper does not contact the frame. A gear ring 2-4 is provided on the outer wall 2-2 of the annular material hopper, and the bottom surface of the gear ring 2-4 also does not contact the frame. When the gear ring 2-4 is driven by the first motor 3, the gear... Ring 2-4 drives the annular material spreading bin to rotate, which can prevent friction between the bottom of the annular material spreading bin and the frame, as well as between the bottom surface of the gear ring 2-4 and the frame. In actual use, the dry material that has been evenly mixed in the mixing tank is loaded into the annular material spreading bin. The first motor 3 drives the gear ring 2-4 and the annular material spreading bin to rotate simultaneously, while the discharge blocking plate 5-4 located inside the annular material spreading bin remains stationary. During the rotation of the annular material spreading bin, the dry powder is scraped and blocked on one side of the discharge blocking plate 5-4. At the same time, when the discharge blocking plate 5-4 passes the discharge port 2-1-1, the dry powder will be evenly spread in the annular filling space between the furnace pit and the forming mold of the smelting furnace through the discharge port 2-1-1, thereby achieving the purpose of automatically spreading material into the annular filling space.
[0028] In this embodiment, a lifting bracket is installed on the frame, and the lifting bracket is located directly above the annular material hopper. A rotating bracket is installed on the lifting bracket, and a tamping plate mechanism is installed on the rotating bracket. In actual use, since the lifting bracket is installed on the vertical lead screw 7, and the vertical lead screw 7 is driven by the second motor 6, when the second motor 6 drives the vertical lead screw 7 to rotate, the lifting bracket can move linearly along the height direction of the vertical lead screw 7, and at the same time drive the rotating bracket and the tamping plate mechanism to move linearly up and down.
[0029] In this embodiment, by setting a sliding guide mechanism between the frame and the lifting support, the stability and accuracy of the lifting support moving linearly along the height direction of the vertical lead screw 7 can be improved.
[0030] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the tamping plate mechanism is installed on a rotating support, which is driven by a third motor 15. During the rotation of the rotating support, the tamping plate mechanism rotates simultaneously with the rotating support. There are at least two tamping plate mechanisms, which are arranged at intervals along concentric circles. Each tamping plate mechanism includes a mounting frame, a vibrating motor 19, a preload spring 20, a tamping rod 13, and a tamping plate 14. In actual use, driven by the rotating support, the tamping positions of at least two tamping plates 14 will rotate along the annular filling space. Under the vibration of the vibrating motor 19, the tamping rod 13 transmits the energy of the vibrating motor 19 to the tamping plate 14, thereby achieving the purpose of gradually tamping the dry material in the annular filling space using at least two tamping plates 14.
[0031] In this embodiment, by setting multiple tamping nails 14-1 on the bottom surface of the tamping plate 14, the multiple tamping nails 14-1 will make holes in the spread dry material layer. During the multiple spreading and compaction processes, the phenomenon of delamination between adjacent compacted dry materials can be avoided, thus improving the compaction effect.
[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the frame includes a bottom rectangular frame 1-1 arranged in parallel, four columns 1-2 respectively installed at the four corners of the bottom rectangular frame 1-1, and a top rectangular frame 1-3 installed at the top of the four columns 1-2. A base plate 1-4 is installed on the bottom rectangular frame 1-1, and a clearance hole is opened in the center of the base plate 1-4 for the forming mold of the melting furnace to pass through. A top plate 1-5 is installed on the top rectangular frame 1-3.
[0033] In this embodiment, the second motor 6 is fixedly installed on the top surface of the top plate 1-5, and the output shaft of the second motor 6 is fixedly connected to the top end of the vertical lead screw 7. Bearing supports are installed on both the bottom rectangular frame 1-1 and the top rectangular frame 1-3, and the two ends of the vertical lead screw 7 are respectively installed on the two bearing supports.
[0034] In this embodiment, each of the four corners of the bottom surface of the base plate 1-4 is provided with a connecting seat. During actual installation, the frame is fixedly installed on the top of the furnace pit through the four connecting seats, and the smelting furnace forming mold passes through the clearance hole, so that the top of the smelting furnace forming mold is higher than the height of the inner sidewall 2-1.
[0035] like Figure 2 As shown, in this embodiment, a drive gear that meshes with the gear ring 2-4 is installed on the output shaft of the first motor 3. At least two pads 5-1 are provided on the bottom end surface of the gear ring 2-4. A first sliding wheel 5-2 for sliding on the upper surface of the base plate 1-4 is installed on the pads 5-1.
[0036] In this embodiment, since there is no contact between the bottom of the annular material hopper and the frame, and between the bottom end face of the gear ring 2-4 and the frame, in order to enhance the stability of the annular material hopper, at least two pads 5-1 are provided on the bottom end face of the gear ring 2-4, and a first sliding wheel 5-2 is installed on the pads 5-1 so that the first sliding wheel 5-2 can slide on the upper surface of the base plate 1-4. That is, under the premise of ensuring that there is no contact between the bottom end face of the gear ring 2-4 and the frame, the stability of the annular material hopper can be enhanced, and the flexibility of the rotation of the annular material hopper can be improved at the same time.
[0037] like Figure 1 , Figure 2 and Figure 3 As shown in this embodiment, the lifting support includes a first fixing plate 8-1 and a second fixing plate 8-2 arranged in parallel. The first fixing plate 8-1 and the second fixing plate 8-2 are connected by a support column 8-3. Both the first fixing plate 8-1 and the second fixing plate 8-2 are threadedly connected to the vertical lead rod 7.
[0038] In this embodiment, a first photoelectric proximity sensor for detecting the upward movement of the first fixed plate 8-1 is installed at the top of any one of the columns 1-2, and a second photoelectric proximity sensor for detecting the downward movement of the second fixed plate 8-2 is installed at the bottom of the column 1-2. Both the first and second photoelectric proximity sensors are connected to the input terminal of the controller, and the second motor 6 is controlled by the controller.
[0039] In actual use, during the upward movement of the lifting bracket, when the first photoelectric proximity sensor detects the upward movement position signal of the first fixed plate 8-1 and transmits it to the controller, the controller controls the second motor 6 to shut down, causing the lifting bracket to stop moving upward, thus limiting the extreme position of the lifting bracket's upward movement; during the downward movement of the lifting bracket, when the second photoelectric proximity sensor detects the downward movement position signal of the second fixed plate 8-2 and transmits it to the controller, the controller controls the second motor 6 to shut down, causing the lifting bracket to stop moving downward, thus limiting the extreme position of the lifting bracket's downward movement.
[0040] In this embodiment, the sliding guide mechanism includes a first sliding guide assembly and a second sliding guide assembly disposed on two diagonally arranged columns 1-2. The first sliding guide assembly includes a right-angled sliding plate 9-1 disposed on one of the columns 1-2 and a roller 9-2 cooperating with the right-angled sliding plate 9-1. The roller 9-2 is mounted on a mounting base 9-3, and the mounting base 9-3 is fixedly mounted on the first fixing plate 8-1 or the second fixing plate 8-2. The second sliding guide assembly includes a vertical guide rail 10-1 disposed on the other column 1-2 and a sliding block 10-2 cooperating with the vertical guide rail 10-1. The sliding block 10-2 is fixedly mounted on the first fixing plate 8-1 or the second fixing plate 8-2.
[0041] In actual use, the cooperation between the right-angled sliding plate 9-1 and the roller 9-2, the cooperation between the vertical guide rail 10-1 and the slide block 10-2, and more importantly, the combined action of the two sets of one-to-one corresponding first sliding guide components and second sliding guide components can improve the stability and accuracy of the lifting bracket driving the rotating bracket and the tamping plate mechanism to move up and down at the same time.
[0042] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the rotating bracket includes a top support plate 12-1 and a bottom support plate 12-2 arranged in parallel. The top support plate 12-1 and the bottom support plate 12-2 are fixedly connected by at least three connecting rods 12-3. The top end of the tamping rod 13 is mounted on the mounting frame. The tamping rod 13 passes through the bottom support plate 12-2. At least two second sliding wheels 21 for sliding on the upper surface of the second fixed plate 8-2 are provided on the bottom surface of the top support plate 12-1.
[0043] In this embodiment, since the top of the ramming rod 13 is mounted on the mounting frame, and the length of the ramming rod 13 is greater than the height of the smelting furnace to be built, the difference between the length of the ramming rod 13 and the height of the smelting furnace to be built is 10cm to 20cm. Therefore, by passing the ramming rod 13 through the bottom support plate 12-2, the stability of the ramming rod 13 can be enhanced by the bottom support plate 12-2.
[0044] In this embodiment, the number of connecting rods 12-3 is twice the number of ramming rods 13, and a connecting rod 12-3 is arranged on both sides of each ramming rod 13, which helps to enhance the stability of the ramming rod 13.
[0045] In this embodiment, by providing at least two second sliding wheels 21 on the bottom surface of the top support plate 12-1, when the rotating bracket rotates, the at least two second sliding wheels 21 can slide on the upper surface of the second fixed plate 8-2, which not only supports the rotating bracket, but also prevents the bottom surface of the top support plate 12-1 from contacting the upper surface of the second fixed plate 8-2, thereby improving the flexibility of the rotating bracket's rotation.
[0046] like Figure 3 As shown, in this embodiment, the third motor 15 is fixedly installed on the bottom surface of the first fixing plate 8-1, and a drive gear 16 is fixedly installed on the output shaft of the third motor 15. A central shaft 11-1 is fixedly installed on the bottom surface of the first fixing plate 8-1, and a bushing 11-2 is fitted on the central shaft 11-1. The bottom end of the bushing 11-2 is fixedly installed on the top support plate 12-1, and a driven gear 17 that meshes with the drive gear 16 is fixedly installed on the outer circular surface of the bushing 11-2.
[0047] like Figure 4 As shown, in this embodiment, the mounting frame includes a bottom pad 18-1 and a top pad 18-2 arranged in parallel. The bottom pad 18-1 and the top pad 18-2 are fixedly connected by at least two support rods 18-3. Push plates 18-4 parallel to the bottom pad 18-1 are slidably fitted on the at least two support rods 18-3. A through hole is opened in the center of the bottom pad 18-1 for the top end of the tamping rod 13 to pass through. The top end of the tamping rod 13 is fixedly installed on the push plate 18-4. The vibration motor 19 is fixedly installed on the top surface of the push plate 18-4. The preload spring 20 is fitted on the support rod 18-3 and is located between the push plate 18-4 and the top pad 18-2.
[0048] In this embodiment, an L-shaped fixing plate is mounted on the top support plate 12-1. A third photoelectric proximity sensor for detecting the upward movement of the upper plate of the I-shaped push frame 18-4 and a fourth photoelectric proximity sensor for detecting the downward movement of the upper plate of the I-shaped push frame 18-4 are installed at intervals on the vertical plate of the L-shaped fixing plate. Both the third and fourth photoelectric proximity sensors are connected to the input terminal of the controller.
[0049] like Figures 1 to 4 As shown, in actual use, the specific process of spreading material in the annular filling space between the furnace pit and the forming mold of the smelting furnace is as follows:
[0050] Turn on the first motor 3, which drives the annular material spreading bin to rotate. Then, pour the set weight of dry powder weighed by the weighing bin 24 in step one into the rotating annular material spreading bin. Under the action of the discharge blocking plate 5-4, the dry material entering the annular material spreading bin is spread into the annular filling space between the furnace pit and the forming mold of the smelting furnace through the discharge port 2-1-1. After all the dry material entering the annular material spreading bin has been spread into the annular filling space, turn off the first motor 3.
[0051] It should be noted that before the second layer of material is laid, the lifting bracket needs to be moved upward to the highest limit position so that the set weight of dry powder weighed by the weighing bin 24 for a single layer of material can be poured into the rotating annular layering bin. Therefore, during the upward movement of the lifting bracket, when the first photoelectric proximity sensor detects the upward movement position signal of the first fixed plate 8-1 and transmits it to the controller, the controller controls the second motor 6 to shut down, so that the lifting bracket stops moving upward.
[0052] In actual use, the specific process of compacting the dry powder in the space of the annular packing includes:
[0053] First, start the second motor 6, which drives the vertical lead screw 7 to rotate clockwise, thereby causing the lifting bracket, rotating bracket and tamping plate mechanism to move vertically downward along the height direction of the vertical lead screw 7.
[0054] Secondly, when the tamping plate 14 contacts the dry material, the rotating support will stop descending, while the lifting support will continue to descend. The pre-compression spring 20 will begin to compress. When the pre-compression spring 20 is compressed to the set position, the third photoelectric proximity sensor detects the upward movement position signal of the upper plate of the I-shaped push frame 18-4 and transmits it to the controller. The controller then controls the second motor 6 to shut down, the lifting support stops descending, and the vibration motor 19 is started. The vibration motor 19 drives the tamping plate 14 to vibrate, and the tamping plate 14 compacts the dry material in the annular filling space once. When the pre-compression spring 20 extends to the set position, the fourth photoelectric proximity sensor detects the downward movement position signal of the upper plate of the I-shaped push frame 18-4 and transmits it to the controller. The controller then controls the vibration motor 19 to shut down.
[0055] Next, the second motor 6 is started, which drives the vertical lead screw 7 to rotate counterclockwise, causing the lifting bracket to move vertically upward along the height direction of the vertical lead screw 7. After the lifting bracket moves upward to a set distance, the third motor 15 is started, which drives the rotating bracket to rotate by a set angle, and then the third motor 15 is turned off.
[0056] Then, the lifting support, rotating support and tamping plate mechanism are repeatedly driven to move vertically downward along the height direction of the vertical screw 7, and the tamping plate 14 tamps the dry powder at different positions in the annular filling space once, until the tamping plate 14 is used to fully tamp the first layer of material in the entire annular filling space.
[0057] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
