The upper induction furnace is mainly composed of furnace body, furnace frame, inductor and cooling system. The outer shell of the furnace body is a steel structure, and the interior is built with refractory bricks, insulation bricks and quartz sand. The inductor consists of a coil, a water jacket, an iron core and a melting groove, which generates heat to melt the metal through electromagnetic induction. The cooling system includes a water jacket and a coil, and adopts a water cooling method to ensure the stable operation of the equipment. When the upper furnace is working, since coal and the like are required for heating, some impurities such as coal ash may fall into the molten copper water. Therefore, the copper water needs to be filtered, and after the filtering is completed, slag removal is also required. However, when the existing slag removal equipment removes impurities, part of the copper water may be mixed with the impurities and removed. This situation will not only lead to the waste of copper water, but also may cause the slag removal equipment to be damaged due to the cooling and hardening of the copper water. In addition, in the metallurgical industry, the high temperature environment has a greater impact on the power output device in the mechanical device.

[0019] See also Figure 1 to Figure 11 In an embodiment of the present invention, a double-bin feeding self-filtering upper-drawing furnace comprises: a furnace body 1, and partitions 2 fixed in the furnace body 1 and symmetrically arranged, and a filtering chamber 203 is formed between the two partitions 2; it also comprises: a filter screen 3, which is installed on one of the partitions 2, and the partition 2 is formed with a collecting groove 201 and a through groove 202 which are connected to each other; a lifting slag scooping mechanism, which is arranged on the furnace body 1, and the lifting slag scooping mechanism is connected with a symmetrically arranged slag scooping plate 15, and the slag scooping plate 15 is formed with a filtering groove 1501, and the lifting slag scooping mechanism can drive the slag scooping plate 15 to move horizontally and vertically. movement in the direction; a filter press mechanism, which is arranged on the lifting slag scooping mechanism, and is connected to a filter press plate 20, and a limit assembly is arranged on the lifting slag scooping mechanism, and the lifting slag scooping mechanism can drive the filter press mechanism to move through the limit assembly to adjust the matching state of the filter press plate 20 and the slag scooping plate 15; an impurity cleaning mechanism, which is arranged on the lifting slag scooping mechanism, and is connected to a push plate 27 slidably connected to the slag scooping plate 15, and the impurity cleaning mechanism can drive the two push plates 27 to move towards or away from each other when the lifting slag scooping mechanism moves.

[0020] Specifically, the furnace body 1 can be divided into a plurality of chambers, namely a first melting chamber, a second melting chamber, a fusion chamber, a purification chamber, and an insulation chamber. The first melting chamber and the second melting chamber are used to heat and melt the raw materials. The molten raw materials will flow through the fusion chamber, the purification chamber, and the insulation chamber in sequence for corresponding treatment. In order to prevent oxygen from entering during the smelting process, a layer of charcoal needs to be covered on the surface of the molten copper. In order to ensure that no impurities are mixed in the molten copper, the molten copper needs to be filtered. The filter screen 3 is installed on one of the partitions 2, and an overflow hole is formed at the bottom of the other partition 2. The raw materials are added into the furnace body 1 and heated to a molten state. The molten raw materials will enter the filter chamber 203 through the overflow hole, and the raw materials will be filtered through the filter screen 3. At this time, under the action of the lifting slag scooping mechanism, the two slag scooping plates 15 are controlled to enter the molten copper and move towards each other. At the same time, in the limit assembly and the filter press mechanism Under the action of the filter press plate 20, the filter press plate 20 is separated from the slag scooping plate 15. When the two slag scooping plates 15 are in contact with each other, under the action of the lifting slag scooping mechanism, the slag scooping plate 15 is controlled to move in a direction away from the copper water. At the same time, under the action of the limiting component and the filter pressing mechanism, the distance between the filter press plate 20 and the slag scooping plate 15 is reduced to filter the impurities, ensuring that the copper water remaining on the slag scooping plate 15 flows back into the filter chamber 203. When the slag scooping plate 15 rises to a certain height, under the action of the limiting component and the filter pressing mechanism, the filter press plate 20 is separated from the slag scooping plate 15 again. At the same time, under the action of the impurity cleaning mechanism, the two push plates 27 move in a direction away from each other to push the impurities remaining on the slag scooping plate 15 into the collecting tank 201 through the through groove 202. The above steps are repeated to achieve the effect of slag scooping the impurities separated from the copper water and automatically cleaning the impurities.

[0022] In detail, the translation assembly includes a first motor 4 fixedly mounted on the furnace body 1, and a bidirectional screw rod 5 connected to the output shaft of the first motor 4 is rotatably mounted on the furnace body 1. A first threaded sleeve 6 symmetrically arranged is threadedly connected to the bidirectional screw rod 5, and the first threaded sleeve 6 is fixedly connected to the receiving plate 7. The furnace body 1 is composed of a plurality of chambers. When the copper water in the furnace body 1 enters the filter chamber 203 through the overflow hole, the impurities remaining in the copper water can be filtered under the action of the filter net 3, and the filtered copper water will enter the adjacent chamber.

[0023] See also Figure 2-Figure 9 , Fig.11 The filter press mechanism includes a second limiting ring 1202 fixedly mounted on the second threaded sleeve 12, the first limiting ring 1201 and the second limiting ring 1202 are located on both sides of the center position of the second threaded sleeve 12, and the first limiting ring 1201 and the second limiting ring 1202 are at equal distances from the center position of the second threaded sleeve 12, a second movable plate 17 slidably connected to the guide column 11 is slidably mounted on the second threaded sleeve 12, a second spring 16 abutting against the second movable plate 17 is sleeved on the second threaded sleeve 12, and a second movable plate 17 is provided A support assembly, wherein the support assembly includes a support sleeve 18 fixedly mounted on the second movable plate 17 and symmetrically arranged, a support rod 19 is slidably mounted on the support sleeve 18, and the support rod 19 is fixedly connected to the filter press plate 20; it also includes a groove 1801 opened on the side wall of the support sleeve 18, a support ring 1901 slidably connected to the groove 1801 is fixed on the support rod 19, a third spring 21 is sleeved on the support sleeve 18, and the two ends of the third spring 21 are respectively abutted against the support ring 1901 and the second movable plate 17.

[0024] See also Figure 6 Before slag removal, the distance between the two first threaded sleeves 6 is the largest, so that the two slag removal plates 15 are located on both sides of the filter chamber 203, and the second threaded sleeve 12 is located at the uppermost end away from the bottom of the furnace body 1, so that the slag removal surface of the slag removal plate 15 and the through groove 202 are in the same horizontal plane. Under the action of the limiting assembly, the first movable plate 14 and the limiting assembly remain in abutment with each other. At this time, the first movable plate 14 cannot continue to move up and is in a separated state with the first limiting ring 1201. At this time, the first spring 13 is in the maximum compression amount, the second spring 16 is in the compression state (minimum compression amount), and the second movable plate 17 and the second limiting ring 1202 are in abutment with each other; the third spring 21 is in a pre-compression state, so that the support rod 19 is located at the end of the stroke away from the support sleeve 18, and the support ring 1901 is located at the end of the stroke on one side of the slot 1801. At this time, the distance between the first movable plate 14 and the second movable plate 17 is the largest, and the filter press plate 20 and the slag removal plate 15 are in a separated state; please refer to Figure 7 When it is necessary to remove slag from the impurities, the second motor 8 works and drives the one-way screw 9 to rotate, thereby driving the second threaded sleeve 12 to move downward, and the first limiting ring 1201 moves synchronously. At this time, under the elastic release of the first spring 13, the limiting function of the limiting assembly is cooperated to make the positions of the first movable plate 14 and the slag removal plate 15 remain unchanged. When the first limiting ring 1201 moves down to abut against the first movable plate 14, the second threaded sleeve 12 continues to move downward, and drives the first movable plate 14 and the slag removal plate 15 to move downward to control the slag removal plate 15 to move toward the direction of the copper liquid; when the second threaded sleeve 12 moves downward, the second threaded sleeve 12 The second movable plate 17 is driven to move downward synchronously, and when the second movable plate 17 moves downward to abut against the limiting assembly, the second movable plate 17 no longer moves downward, the second threaded sleeve 12 continues to maintain the downward state, and the first movable plate 14 continues to move downward under the action of the first limiting ring 1201, and the second spring 16 is continuously squeezed. When the bottom of the second threaded sleeve 12 moves to abut or nearly abut against the support plate 10, the second motor 8 stops working, and the slag scooping plate 15 is now in the copper water (below the impurities), and the distance between the first movable plate 14 and the second movable plate 17 is smaller than the distance between the two in the initial state, ensuring that the impurity cleaning mechanism does not move.

[0025] Subsequently, the first motor 4 works and controls the two first threaded sleeves 6 to move in a direction approaching each other, so as to control the two slag scooping plates 15 to move in a direction approaching each other. Since the slag scooping plates 15 are slidably connected to the filter chamber 203, it is ensured that the first threaded sleeves 6 move along the length direction of the bidirectional screw rod 5 and will not rotate with the bidirectional screw rod 5. When the ends of the two slag scooping plates 15 abut against each other, the first motor 4 stops working, and the second motor 8 controls the unidirectional screw rod 9 to reverse, so that the slag scooping plates 15 move up, while the second movable plate 17 is in abutment with the limit assembly, and the second spring 16 is elastically released. Under the limiting action of the limiting assembly, the positions of the second movable plate 17 and the filter press plate 20 remain unchanged. When the slag scooping plate 15 drives the impurities to move up to the position abutting the filter press plate 20, the impurities are filtered under the action of the pressure under the filter press plate 20 to squeeze out the copper water mixed in the impurities. The copper water will flow back to the filter chamber 203 through the filter tank 1501. At this time, the second threaded sleeve 12 continues to move up and drives the second limiting ring 1202 to move up. When the second limiting ring 1202 moves up to the position abutting the second movable plate 17, it drives the second movable plate 17 and the filter press plate 20 to move up.

[0026] When the slag scooping plate 15 moves up to the initial height, the first movable plate 14 abuts against the limiting assembly again, so that the first movable plate 14 no longer moves up, and the second threaded sleeve 12 continues to move, driving the second movable plate 17 to continue to move up through the second limiting ring 1202 until the second threaded sleeve 12 returns to the initial height and the second motor 8 stops working.

[0027] Preferably, the slag scooping plates 15 are arranged in an L shape. When slag scooping is performed, since the distance between the two slag scooping plates 15 is the largest in the initial state, when the slag scooping plates 15 enter the molten copper, the slag scooping plates 15 will move in a direction close to each other, so that impurities gradually gather. When the two slag scooping plates 15 abut against each other, the slag scooping plates 15 move in a direction away from the molten copper. Since the molten copper has a certain fluidity, the molten copper remaining on the impurities will be discharged through the filter tank 1501, ensuring that the molten copper will not be discharged along with the impurities during the slag scooping process.

[0028] Through the cooperation and separation of the filter press plate 20 and the slag scooping plate 15, it can be achieved that during the slag scooping process of the slag scooping plate 15, the filter press plate 20 and the slag scooping plate 15 are in a separated state to ensure that the slag scooping is not affected. After the slag scooping of the slag scooping plate 15 is completed, the filter press plate 20 abuts against the slag scooping plate 15 to perform filter pressing treatment on the residual copper water to ensure that the copper water is not wasted due to slag scooping. When the filter pressing is completed, the filter press plate 20 is automatically controlled to separate from the slag scooping plate 15 to ensure that the subsequent treatment of impurities on the slag scooping plate 15 is not affected.

[0029] See also Figure 2-Figure 8 The limiting assembly includes a first fixed block 1101 and a second fixed block 1102 fixedly mounted on the guide column 11, a first limiting groove 1401 cooperating with the first fixed block 1101 is formed on the first movable plate 14, and a second limiting groove 1701 cooperating with the second fixed block 1102 is formed on the second movable plate 17.

[0030] Furthermore, the first fixed block 1101 can smoothly pass through the first limiting groove 1401 and abut against the second movable plate 17. The second fixed block 1102 can smoothly pass through the second limiting groove 1701 and abut against the first movable plate 14. In the initial state, the distance between the slag scooping plate 15 and the receiving plate 7 is the smallest, and the first movable plate 14 and the second fixed block 1102 are in abutment state, so that the position of the slag scooping plate 15 no longer changes. When slag scooping is required, the second threaded sleeve 12 will move toward the copper liquid direction, so that the first spring 13 is elastically released until the first movable plate 14 abuts against the first limiting ring 1201. A movable plate 14 will be separated from the second fixed block 1102. During this process, the second movable plate 17 always moves synchronously with the second threaded sleeve 12, so that the filter press plate 20 moves to the matching position with the slag scooping plate 15, and under the action of the second limiting groove 1701, it smoothly passes through the second fixed block 1102. As the second threaded sleeve 12 continues to move, under the action of the first limiting groove 1401, the first movable plate 14 will pass through the first fixed block 1101, and the second movable plate 17 will abut against the first fixed block 1101, so that the second movable plate 17 will no longer move. At this time, the filter press plate 20 will be separated from the slag scooping plate 15.

[0031] Preferably, when the slag scooping is completed, the second threaded sleeve 12 moves toward the initial position, and the second spring 16 is elastically released, so that the position of the second movable plate 17 remains unchanged, until the second movable plate 17 abuts against the second limiting ring 1202, and the second movable plate 17 will be separated from the first fixed block 1101. During this process, the first movable plate 14 always moves synchronously with the second threaded sleeve 12, so that the slag scooping plate 15 moves to the matching position with the filter press plate 20 to filter the impurities, and under the action of the first limiting groove 1401, the first movable plate 14 will smoothly pass through the first fixed block 1101. As the second threaded sleeve 12 continues to move, under the action of the second limiting groove 1701 When the filter press plate 20 is in operation, the second movable plate 17 will pass through the second fixed block 1102, and the first movable plate 14 will abut against the second fixed block 1102, so that the position of the first movable plate 14 will no longer change. At this time, the filter press plate 20 is separated from the slag scooping plate 15 again. Through the cooperation of the first fixed block 1101, the second fixed block 1102, the first limiting groove 1401, and the second limiting groove 1701, the slag scooping plate 15 and the filter press plate 20 can be controlled to be in a separated state during the slag scooping process. After the slag scooping plate 15 completes the slag scooping, the impurities are filtered through the filter press plate 20, and after the filtering is completed, it is automatically separated from the slag scooping plate 15, so that the subsequent impurity cleaning mechanism can clean the impurities on the slag scooping plate 15.

[0032] Through the giving way and interference cooperation between the first fixed block 1101, the second fixed block 1102 and the first limiting groove 1401 and the second limiting groove 1701, the filter press plate 20 and the slag scooping plate 15 can be moved closer to and farther away from each other, thereby reducing the required driving source and the cost of the entire slag scooping, and the accuracy of the transmission can be ensured to accurately adjust the positional relationship between the filter press plate 20 and the slag scooping plate 15.

[0033] See also Figure 2 , Figure 3 , Figure 5 , Figure 8-Figure 11The impurity cleaning mechanism includes a rotating rod 22 rotatably mounted on the first movable plate 14, and a straight groove 2201, a first spiral groove 2202, and a second spiral groove 2203 are provided on the rotating rod 22. A follower sleeve 23 is fixed on the second movable plate 17, and a first limit block 2301 slidably connected to the straight groove 2201 and the first spiral groove 2202 is fixed on the inner wall of the follower sleeve 23. A follower assembly is provided on the rotating rod 22, wherein the follower assembly includes a movable sleeve 24 slidably mounted on the rotating rod 22, and a second limit block 2401 slidably engaged with the second spiral groove 2203 is fixed on the inner wall of the movable sleeve 24. A connecting plate 25 is fixed on the movable sleeve 24, and a symmetrically arranged connecting rod 26 is hinged on the connecting plate 25, and the connecting rod 26 is hinged to the push plate 27.

[0034] Furthermore, a fourth spring 28 is installed between the two connecting rods 26. When the slag scooping plate 15 is located in the copper water and is in a position ready to scoop up slag, at this time, the filter press plate 20 and the slag scooping plate 15 are in a separated state, the first limit block 2301 is located in the middle position of the straight groove 2201, and the second limit block 2401 is located at the end of the stroke of the second spiral groove 2203 toward the straight groove 2201 side, so that the two push plates 27 are controlled to be in a state of mutual contact through the connecting rod 26, and the fourth spring 28 is in a stretched state, so that the two push plates 27 have a tendency to move toward each other through the connecting rod 26. When the slag scooping is completed, the second threaded sleeve 12 moves toward the receiving plate 7. The first movable plate 14 will drive the rotating rod 22 to move, so that the first limiting block 2301 slides in the straight groove 2201. Under the action of the first limiting block 2301 and the straight groove 2201, it is ensured that the rotating rod 22 does not rotate, so as to lock the position of the movable sleeve 24 through the second spiral groove 2203 and the second limiting block 2401. At this time, the two push plates 27 will not move, and the filter press plate 20 will filter the impurities on the slag plate 15. After the filter press treatment is completed, the second limiting ring 12 02 is in contact with the second movable plate 17, so the first movable plate 14 and the second movable plate 17 move upward synchronously. When the slag scooping plate 15 moves to the same height as the through groove 202, the first movable plate 14 is in contact with the second fixed block 1102, so that the position of the slag scooping plate 15 remains unchanged, and the second movable plate 17 continues to move, so that the filter press plate 20 moves in the direction away from the slag scooping plate 15. The second movable plate 17 will also drive the follower sleeve 23 to move, thereby controlling the first limit block 2301 to slide along the straight groove 2201 until the first limit block 2301 is separated from the straight groove 2201 and enters the first spiral groove 2202, and the rotating rod 22 will rotate to drive the second spiral groove 2202 to rotate. The groove 2203 moves, and under the action of the second limit block 2401, the movable sleeve 24 moves toward the first movable plate 14, so as to drive the connecting rod 26 to move through the connecting plate 25, so that the two push plates 27 move in the direction away from each other, so as to push the impurities picked up by the slag scooping plate 15 toward the through groove 202 and enter the collecting groove 201 through the through groove 202. By controlling the first movable plate 14 and the second movable plate 17 to approach or move away from each other, the push plate 27 can be controlled to move in the direction of approaching or moving away from each other, so as to realize that after the slag scooping plate 15 completes the slag scooping, the impurities are automatically pushed into the collecting groove 201, so as to ensure that the slag scooping of the molten copper can be continuously performed.

[0035] Specifically, during the process of the push plate 27 pushing impurities, the stretching amount of the fourth spring 28 increases. When the push plate 27 is reset, the fourth spring 28 elastically contracts to assist the two push plates 27 in resetting and reduce the downward pressure applied to the first movable plate 14, ensuring that during the resetting process, the first movable plate 14 always remains in abutment with the second fixed block 1102.

[0036] A self-filtration method for a double-bin feeding self-filtration upper induced furnace comprises the following steps: Step 1: Add the raw materials into the furnace body 1, and after the raw materials are heated and melted, transport them into the filter chamber 203; Step 2: filtering the molten material under the action of the filter screen 3; Step 3: Under the action of the lifting slag scooping mechanism, the slag scooping plate 15 is driven to enter the copper liquid and move in a direction close to each other. Under the action of the limit assembly, the filter press mechanism controls the filter press plate 20 to separate from the slag scooping plate 15; Step 4: When the two slag scooping plates 15 are in contact with each other, the lifting slag scooping mechanism controls the slag scooping plate 20 to separate from the copper water. Under the action of the limit assembly, the filter press mechanism controls the filter press plate 20 to perform a filter press action on the impurities. After the filter press is completed, the impurities remaining on the slag scooping plate 15 are cleaned by the impurity cleaning mechanism and the push plate 27.
