DETAILED DESCRIPTION

[0020] like Figure 1-Figure 7 As shown, an alloy adding device and adding method for metal smelting include a smelting device 1 and a funnel 2 arranged above the smelting device 1, a material guide frame 3 is fixedly installed at the bottom opening of the funnel 2, the material guide frame 3 is located at the feed inlet at the top of the smelting device 1 and is connected to the smelting device 1 by welding. In actual use, the raw materials to be added can be introduced into the smelting device 1 through the funnel 2.

[0021] In order to quantitatively transport the raw materials, a transverse shaft 14 is installed at the center of the guide frame 3, and a sleeve 6 is sleeved on the outer side of the transverse shaft 14. Figure 3 As shown, the interior of the material guide frame 3 is a cavity structure, and the left and right sides of the cavity are both set as arc surfaces, the center of the arc surface coincides with the axis of the horizontal axis 14, and the top and bottom ends of the material guide frame 3 are both provided with through grooves, and the through grooves are connected to the cavity in the material guide frame 3, so that the raw materials passing through the funnel 2 can enter the material guide frame 3; Furthermore, a plurality of partitions 7 are evenly arranged on the outer circumferential surface of the sleeve 6. The plurality of partitions 7 are distributed in a circular array on the outside of the sleeve 6 and are fixedly connected to the sleeve 6. In the present embodiment, the number of partitions 7 is preferably four, and the span between two adjacent partitions 7 is greater than the width of the through groove, thereby facilitating the transportation of raw materials between two adjacent partitions 7 through the through groove.

[0022] In order to drive the sleeve 6 to rotate, a motor is installed at one end of the guide frame 3 in this solution, and the end of the sleeve 6 passing through the guide frame 3 is connected to the output shaft of the motor. Figure 3As shown, an extrusion assembly is provided on the side of the partition 7 and at a position away from the sleeve 6, and a traction assembly connected to the extrusion assembly is provided at one end of the partition 7 close to the sleeve 6. In the process of the traction assembly moving inward relative to the sleeve 6, the extrusion assembly can move outward relative to the partition 7. The outer side of the transverse axis 14 is sleeved with a first retaining ring 15 and a second retaining ring 16, and the first retaining ring 15 and the second retaining ring 16 are located on both sides of the traction assembly. The first retaining ring 15 and the second retaining ring 16 are both installed with a first switch 20 electrically connected to the above-mentioned motor. In actual use, when the partition 7 passes through the through groove above the guide frame 3 and enters the arc surface and the traction assembly moves inward relative to the sleeve 6, it can contact the above-mentioned first switch 20, so that the motor can be controlled to run in reverse through the first switch 20. Figure 3 As shown, the space enclosed by the arc surface of the two adjacent partitions 7 and the inner cavity of the material guide frame 3 is a accommodating chamber. Under normal feeding state, the accommodating chamber is in a saturated state. When material jamming occurs or material feeding is not smooth, the falling raw materials cannot fill the accommodating chamber. At this time, the extrusion assembly on the partition 7 has space to be discharged, so that the traction assembly can move inward relative to the sleeve 6 and contact the first switch 20, so as to change the running direction of the motor and prevent the unsaturated raw materials in the accommodating chamber from being put into the smelting device 1.

[0023] like Figure 3-Figure 6 As shown, the extrusion assembly includes a first slide plate 8 and a second slide plate 9 which are arranged on both sides of the partition 7. The first slide plate 8 and the second slide plate 9 are elastically matched with the partition 7, and the first slide plate 8 and the second slide plate 9 are located at one end of the partition 7 away from the sleeve 6. The inner sides of the first slide plate 8 and the second slide plate 9 are fixedly provided with a pressure block 22.

[0024] The traction assembly includes a first pull rod 11 and a second pull rod 12 which are elastically matched with the partition 7. The first pull rod 11 and the second pull rod 12 are both located at one end of the partition 7 close to the sleeve 6. A pull rope 10 is fixedly provided at one end of the first pull rod 11 and the second pull rod 12 away from the sleeve 6. A protrusion 23 is fixedly provided at one end of the pull rope 10 away from the sleeve 6. The protrusion 23 is located on the side of the pressure block 22 away from the sleeve 6, and the opposite sides of the pressure block 22 and the protrusion 23 are both set as inclined surfaces. The above-mentioned pull rope 10 passes through the partition 7 and slidably cooperates with it. Through this structure, when the first pull rod 11 or the second pull rod 12 is in a pop-up state, the protrusion 23 can be pulled by the pull rope 10, and the pressure between the protrusion 23 and the pressure block 22 can prompt the first slide 8 and the second slide 9 to move outward relative to the partition 7.

[0025] In order to position the first pull rod 11 and the second pull rod 12, an electromagnet 18 is arranged on the side of the first pull rod 11 and the second pull rod 12 facing away from each other, and a connecting plate is elastically installed on one side of the electromagnet 18, and the connecting plate is made of iron. Figure 4-Figure 5 As shown, a slot 13 is provided on one side of the first pull rod 11 and the second pull rod 12 close to the electromagnet 18, and a block 17 matching the slot 13 is fixedly provided on the side of the connecting plate away from the electromagnet 18. When the block 17 at the first pull rod 11 or the second pull rod 12 is in a pop-up state and inserted into the slot 13, the first pull rod 11 or the second pull rod 12 is in a locked state.

[0026] The partition 7 is provided with a second switch 26 on the inner side of the first slide plate 8 and the second slide plate 9. Figure 3 Combination Figure 4 As shown, in the clockwise direction, the second switch 26 on the second slide plate 9 on the partition 7 is electrically connected to the electromagnet 18 on the first pull rod 11 on the adjacent partition 7 (the partition 7 indicated in the clockwise direction). Figure 3 Combination Figure 4 As shown, in the counterclockwise direction, the second switch 26 on the partition 7 on the side of the first slide 8 is electrically connected to the electromagnet 18 on the side of the second pull rod 12 on the adjacent partition 7 (the partition 7 indicated in the counterclockwise direction). From another perspective, the second switch 26 on one side of the accommodating chamber will control the electromagnet 18 on the other side of the accommodating chamber.

[0027] Reference Figure 5-Figure 10 As shown, the first retaining ring 15 and the second retaining ring 16 are provided with an annular groove 19 on the opposite side. Figure 9-10 As shown, the first retaining ring 15 and the second retaining ring 16 are both provided with a guide plate 21, the guide plate 21 is arc-shaped, a recess 27 is provided at the inner peripheral wall of the annular groove 19, the first switch 20 is installed at the bottom end of the inner cavity of the recess 27, and the guide plate 21 is installed at the recess 27. In the initial state, the guide plate 21 is tilted so that a guide channel is left between one end of the guide plate 21 and the recess 27, and the inclination direction of the guide plate 21 on the first retaining ring 15 and the second retaining ring 16 is opposite, refer to Figure 8 As shown, a protrusion 24 is fixedly provided on one side of the first pull rod 11 close to the first retaining ring 15 and on one side of the second pull rod 12 close to the second retaining ring 16. The protrusion 24 is slidably provided in the annular groove 19. Figure 3 as well as Figure 10-11Only when the sleeve 6 rotates counterclockwise, the protrusion 24 on the first pull rod 11 can enter the recess 27 through the guide channel on the first baffle ring 15. Similarly, when the sleeve 6 rotates clockwise, the protrusion 24 on the second pull rod 12 can enter the recess 27 from the guide channel on the second baffle ring 16.

[0028] Here, the installation position of the guide plate 21 is further limited. Specifically, when the sleeve 6 rotates counterclockwise so that the partition 7 passes through the through groove and enters the curved surface structure on the guide frame 3, the first pull rod 11 on the partition 7 can move to the vicinity of the guide plate 21 on the first retaining ring 15. Similarly, when the sleeve 6 rotates clockwise so that the partition 7 passes through the through groove and enters the curved surface, the second pull rod 12 on the partition 7 can move to the vicinity of the guide plate 21 on the second retaining ring 16.

[0029] In actual use, the raw materials to be added are introduced into the material guide frame 3 through the funnel 2 and finally fall between two adjacent partitions 7. At this time, the sleeve 6 is driven by an external motor to rotate a certain angle (since the number of partitions 7 in this article is preferably four, the motor drives the sleeve 6 to rotate intermittently, each time rotating 90°), so that the adjacent partitions 7 without raw materials can be rotated to the upper through slots of the material guide frame 3, and the adjacent partitions 7 loaded with raw materials are rotated to the lower through slots on the material guide frame 3. In this process, the raw materials loaded between the adjacent partitions 7 can be put into the smelting device 1; When the raw material loaded between two adjacent partitions 7 is not saturated, refer to Figure 3 As shown, as the sleeve 6 rotates counterclockwise, the two partitions 7 will rotate to the arc surface structure of the material guide frame 3. Figure 3The accommodating chamber a in the accommodating chamber a is filled, therefore, the first slide plate 8 located at the partition 7 above the accommodating chamber a can move relative to the partition 7, and the second slide plate 9 on the partition 7 below the accommodating chamber a is squeezed by the raw material and is in a contracted state, so that the second slide plate 9 can contact the second switch 26 on one side thereof, so that the electromagnet 18 on the side of the first pull rod 11 above the accommodating chamber a is in an energized state, and the suction force of the electromagnet 18 on the connecting plate can prompt the card block 17 to move out of the card slot 13, so that the first pull rod 11 above the accommodating chamber a can slide freely relative to the sleeve 6. Specifically, when the partition 7 above the accommodating chamber a continues to rotate, the first pull rod 11 on the partition 7 will move to the guide plate 21 on the first retaining ring 15, so that the first pull rod 11 The protrusion 24 on the rod 11 eventually passes through the gap between the guide plate 21 and the recessed portion 27 and enters the recessed portion 27. Since the inner peripheral wall of the annular groove 19 has lost its limit on the protrusion 24 and the raw material in the accommodating chamber a is not saturated, the first slide plate 8 above the accommodating chamber a can slide freely relative to the partition 7, so that the first pull rod 11 can drive the protrusion 24 to move toward the direction close to the sleeve 6 and finally contact the first switch 20 (the first switches 20 at the two recessed portions 27 are used to control the forward and reverse rotation of the motor), thereby changing the running direction of the motor, so that the motor can drive the sleeve 6 to rotate clockwise, which can prevent the unsaturated raw material between the two partitions 7 from being put into the smelting device 1, which is conducive to controlling the amount of raw material put in; Similarly, when the sleeve 6 rotates clockwise, the protrusion 24 on the second pull rod 12 will cooperate with the recessed portion 27 on the second retaining ring 16. From the above analysis, it can be seen that when the sleeve 6 rotates clockwise and the two adjacent partitions 7 are not loaded and saturated, after the two adjacent partitions 7 move to the arc position on the guide frame 3, the second pull rod 12 located on the upper partition 7 will drive the protrusion 24 on one side thereof to move in the recessed portion 27 on the second retaining ring 16 and finally contact the first switch 20, so as to change the running direction of the motor; According to the above analysis, when the space between the two partitions 7 is fully loaded with materials and reaches the curved surface of the material guide frame 3, the first slide plate 8 or the second slide plate 9 on the partition 7 is blocked by the materials and cannot slide out, so that the first pull rod 11 or the second pull rod 12 cannot drive the protrusion 24 to move in the recess 27, so that the sleeve 6 maintains its original rotation direction, which is conducive to putting the materials into the smelting device 1.

[0030] To sum up, this device can detect whether the material in the accommodating chamber a is in a full load state by setting the first slide plate 8 and the second slide plate 9 during the counterclockwise or clockwise rotation of the sleeve 6. When the material in the accommodating chamber a is not fully loaded, the first pull rod 11 or the second pull rod 12 will drive the protrusion 24 to move and contact the first switch 20, so as to change the rotation direction of the sleeve 6, which can prevent the material in the accommodating chamber a that is not fully loaded from being put into the smelting device 1, which is beneficial to the precise control of the amount of raw materials put in.

[0031] Reference Figure 1-Figure 2 As shown, both ends of the sleeve 6 pass through the material guide frame 3 and are rotatably matched therewith through bearings, and a driven gear 4 is fixedly sleeved on one end of the sleeve 6 close to the motor, and the output shaft of the motor is equipped with a driving gear meshing with the driven gear 4, and both ends of the horizontal axis 14 pass through the sleeve 6, and brackets 5 are fixedly provided at both ends of the horizontal axis 14, and the brackets 5 are fixedly connected to the material guide frame 3.

[0032] Reference Figure 3 As shown, in actual use, the partition plate 7 will contact the arc surface on the material guiding frame 3 during the rotation process.

[0033] Reference Figure 4 As shown, the partition plate 7 is provided with two strip grooves, and the first pull rod 11 and the second pull rod 12 are slidably arranged in the strip grooves, and a first spring is fixedly arranged between the first pull rod 11 and the inner end surface of the strip groove, and between the second pull rod 12 and the inner end surface of the strip groove.

[0034] The partition plate 7 is provided with two slide grooves, and the first slide plate 8 and the second slide plate 9 are both slidably arranged in the slide grooves. A second spring is fixedly arranged between the first slide plate 8 and the inner end surface of the slide groove, and between the second slide plate 9 and the inner end surface of the slide groove.

[0035] Reference Figure 5 As shown, the sleeve 6 is provided with a mounting groove for installing the electromagnet 18, so that the electromagnet 18 is fixedly arranged at the inner end surface of the mounting groove, and the connecting plate is slidably arranged in the mounting groove, and a spring is fixedly arranged between the connecting plate and the electromagnet 18, and the sleeve 6 is provided with a through groove for slidingly fitting the first pull rod 11 and the second pull rod 12, and the above-mentioned mounting groove is connected to this through groove.

[0036] Reference Figure 5 , Figure 8-Figure 11As shown, a round shaft 2101 is fixedly provided on one side of the guide plate 21 close to the end face of the annular groove 19. The round shaft 2101 can be arranged at the center of the guide plate 21. Through this structure, when the protrusion 24 moves out of the recessed portion 27, the protrusion 24 can cause the guide plate 21 to rotate around the round shaft 2101, which is conducive to the protrusion 24 moving out of the recessed portion 27. A stepped hole matching the round shaft 2101 is opened at the inner end face of the annular groove 19. The round shaft 2101 is rotatably installed at the stepped hole through a bearing, and the outer side of the round shaft 2101 A coil spring 25 is sleeved, and the two ends of the coil spring 25 are fixedly connected to the outer wall of the circular shaft 2101 and the inner wall of the stepped hole respectively. Through this structure, in the initial state, the guide plate 21 can be in an inclined state, so that a gap is left between the guide plate 21 and the recessed portion 27. When the sleeve 6 rotates clockwise and the protrusion 24 on the side of the first pull rod 11 passes through the guide plate 21, the protrusion 24 can squeeze the guide plate 21 to deflect it in the direction close to the first switch 20 and finally be located at the end of the recessed portion 27, so that the protrusion 24 can return to the inner peripheral wall of the annular groove 19.

[0037] Reference Figure 6 As shown, the second switch 26 is installed at the inner end surface of the slide slot.

[0038] A guide groove is provided at the inner end surface of the slide groove. The cross sections of the protrusion 23 and the guide groove can be set to be T-shaped, and the end of the protrusion 23 away from the pressing block 22 is slidably set in the guide groove.
