Description

Technical Field

[0001] The invention relates to the technical field of batching and conveying, and in particular to a batching and conveying device. Background Art

[0002] In the process of refining rare metals and their alloys, tin, nickel and other metals in a melting furnace, it is usually necessary to use a special batching conveying device to transport the batching to replenish the refining raw materials in the melting furnace. Generally, the steelmaking raw materials need to be fed into the furnace cavity of the electric furnace by a charging car. The existing charging car uses a vibration motor as a vibration source when unloading, so that the batching slides into the furnace cavity of the electric furnace through the discharge port as the material box vibrates.

[0003] For example, the Chinese patent with publication number CN221069802U, entitled "A Vibrating Charger for an Electric Furnace". When the vibrating charger is in use, the fixing buckle is opened to place the lower part of the track cleaning box on the fixed guide rail, and the track cleaning block inside the track cleaning box is close to the track. When the vibrating charger moves forward or backward, the wheels rotate to provide a power source. At this time, the belt is in a taut state. Under the transmission action of the belt, the coaxial turntable and the first roller are driven to rotate. Since a crank slider structure is formed between the first roller, the connecting rod and the track cleaning block, the quick return characteristic of the crank slider is utilized. The track cleaning block will have an acceleration process when moving along the fixed guide rail, and combined with the speed of the charging car, the track cleaning block can remove hard objects adhering to the fixed guide rail.

[0004] Regarding the above-mentioned related technologies, due to the high temperature of the furnace mouth, the conveying device is close to the furnace mouth for a long time, which is easy to accelerate the aging of the electrical components of the conveying device and increase the maintenance frequency. In addition, when the raw materials fall into the electric furnace, the molten metal in the electric furnace will splash upward, which not only threatens the safety of the operators, but also the molten metal splashes onto the track surface and cools and condenses, which will cause the charging car to move jammed, which is not conducive to the transportation of metal ingredients. Summary of the invention

[0005] In view of this, the present invention provides a batching and conveying device, aiming to solve the problem that the conveying device is close to the furnace mouth for a long time, which may accelerate the aging of the electrical components of the conveying device, and the molten metal splashes onto the track surface and cools and condenses, causing the charging car to move jammed.

Reducing the moving distance of the bracket close to the melting furnace can also shorten the length of the chute and increase the distance between the chute and the melting furnace, thereby reducing the amount of molten metal in the melting furnace splashing into the chute and reducing the probability of the first roller getting stuck. In addition, the conveyor plate rotates to an inclined state to convey the ingredients to the melting furnace, and the molten metal in the melting furnace splashes upward to the upper surface of the conveyor plate, that is, the conveyor plate blocks the molten metal splashing upward, reducing the amount of molten metal splashing to the bottom of the hopper and reducing the probability of the hopper getting stuck relative to the loading shell.

[0009] By adopting the above technical solution, the distance moved by the transmission rack is twice that of the transmission gear, and the rear side plate moves synchronously with the transmission rack, so that the rear side plate can move toward the inside of the upper material shell relative to the second side plate, so that the rear side plate can push the ingredients in the hopper to move closer to the discharge port, thereby improving the efficiency of conveying the ingredients in the hopper to the melting electric furnace.

[0010] Optionally, an inner lining plate is provided in the hopper, and the inner lining plate is used to block ingredient debris in the hopper.

[0011] Optionally, the first roller can move along the length direction of the slide groove, and the bottom wall of the support platform is rotatably connected to a second roller, and the second roller is used to drive the support platform to move along the width direction of the slide groove.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the Figure 1-Figure 8 of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art shall fall within the scope of protection of the present invention.

[0032] This embodiment provides a batching conveying device. Referring to Figure 1 and Figure 2 , a batching conveying device includes a support platform 1, a chute 11 opened inside the support platform 1, a bracket 2, a first roller 21, a feeding housing 22 for conveying batching, a linear actuator 3 for driving the feeding housing 22 to tilt, and a vibration source 4 fixedly connected to the outer side surface of the feeding housing 22. The first roller 21 is rotatably connected to the bottom surface of the bracket 2 and is used to drive the bracket 2 to move along the length direction of the chute 11. Four linear actuators 3 are provided. The two linear actuators 3 on the left are fixedly connected to the bracket 2, and the two linear actuators 3 on the right are slidably connected to the bracket 2. The drive shaft of the linear actuator 3 is hinged to the feeding housing 22.

[0033] Referring to Figure 1 , Figure 3 and Figure 4 , the cross-section of the feeding housing 22 is in a "U" shape. A hopper 5 is slidably connected to the feeding housing 22 along the axial direction. A first rotating source 6 is fixedly connected to the bottom surface of the feeding housing 22. The first rotating source 6 is fixedly connected to a driving lead screw 61, and the driving lead screw 61 is threadedly connected to the hopper 5. The driving lead screw 61 and the hopper 5 form a lead screw-slider mechanism. The first rotating source 6 drives the driving lead screw 61 to rotate, so that the hopper 5 moves out of the feeding housing 22 and at the same time moves the hopper 5 closer to the melting electric furnace.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The bottom wall of the hopper 5 is provided with discharge ports 51 at both ends along the axial direction. The two discharge ports 51 enable the hopper 5 to load materials to the melting electric furnaces on the left and right sides. During the loading process, only one discharge port 51 is opened, and the other discharge port 51 is always closed. The side wall of the discharge port 51 is hinged with a feed plate 52, which is hinged on the sides of the two discharge ports 51 that are close to each other. When the hopper 5 moves into the loading housing 22, the inner bottom surface of the loading housing 22 abuts against the lower bottom surface of the feed plate 52, and the feed plate 52 can close the discharge port 51. A return torsion spring 53 is hinged between the feed plate 52 and the hopper 5.

[0035] When the hopper 5 moves out of the loading shell 22, the hopper 5 is driven to move closer to the melting furnace relative to the loading shell 22, so that the moving distance of the bracket 2 close to the melting furnace is reduced during the process of loading the melting furnace, the heat received by the parts between the bracket 2 and the loading shell 22 from the melting furnace is reduced, and the aging rate of the parts between the bracket 2 and the loading shell 22 due to high temperature is reduced. Reducing the moving distance of the bracket 2 close to the melting furnace can also shorten the length of the chute 11, thereby increasing the distance between the chute 11 and the melting furnace, thereby reducing the amount of molten metal in the melting furnace splashing into the chute 11, and reducing the probability of the first roller 21 getting stuck. In addition, the conveying plate 52 rotates to an inclined state to convey the ingredients to the melting furnace, and the molten metal in the melting furnace splashes upward to the upper surface of the conveying plate 52, that is, the conveying plate 52 blocks the molten metal splashing upward, reducing the amount of molten metal splashing to the bottom surface of the hopper 5, and reducing the probability of the hopper 5 getting stuck relative to the loading shell 22.

[0036] Reference Figure 5 and Figure 6The hopper 5 includes a front side plate 54, a rear side plate 55, a connecting side plate 56 and a bottom plate 57. The front side plate 54 and the rear side plate 55 are arranged opposite to each other. The connecting side plate 56 is provided with a sliding groove 562 along the length direction of the feeding housing 22. The front side plate 54 and the rear side plate 55 are slidably connected to the connecting side plate 56 through the sliding groove 562. There are two connecting side plates 56, and the two connecting side plates 56 are arranged opposite to each other. The connecting side plate 56 abuts against the inner side surface of the feeding housing 22, and the connecting side plate 56 is fixedly connected to the bottom plate 57, and the bottom plate 57 is threadedly connected to the transmission screw 61. The outer side surface of the connecting side plate 56 is rotatably connected with a transmission gear 561, a transmission rack 541 is fixedly connected between the front side plate 54 and the rear side plate 55, and a supporting rack 221 is fixedly connected to the side wall of the loading housing 22. The transmission rack 541 and the supporting rack 221 are arranged on the upper and lower sides of the transmission gear 561, and the transmission rack 541 and the supporting rack 221 are arranged opposite to each other, and the transmission rack 541 and the supporting rack 221 can mesh with the transmission gear 561. An inner lining plate 58 is arranged in the hopper 5, and two inner lining plates 58 are arranged. The inner lining plates 58 abut against the inner side surface of the connecting side plate 56 to prevent the batching debris from entering the sliding groove 562.

[0037] When the transmission screw 61 drives the bottom plate 57 to move out of the loading housing 22, the connecting side plate 56 moves synchronously with the bottom plate 57, and the connecting side plate 56 drives the transmission gear 561 to move synchronously. When the transmission gear 561 moves, the fixed support rack 221 drives the transmission gear 561 to rotate, thereby causing the transmission gear 561 to rotate and move along the length direction of the hopper 5, and the transmission gear 561 drives the transmission rack 541 to move.

[0038] The transmission gear 561 can drive the transmission rack 541 to move when it only moves but does not rotate, and the transmission gear 561 can drive the transmission rack 541 to move when it only rotates but does not move. Therefore, the moving distance of the transmission rack 541 is twice that of the transmission gear 561. The rear side plate 55 moves synchronously with the transmission rack 541, so that the rear side plate 55 can move toward the inside of the upper material shell 22 relative to the second side plate, so that the rear side plate 55 can push the ingredients in the hopper 5 to move closer to the discharge port 51, thereby improving the efficiency of conveying the ingredients in the hopper 5 to the melting electric furnace.

[0039] At the same time, the transmission rack 541 drives the front side plate 54 to move outside the supporting shell 71, and the molten metal in the melting electric furnace splashes upward on the inner surfaces of the front side plate 54 and the two connecting side plates 56. The front side plate 54 and the two connecting side plates 56 block the molten metal, reducing the threat posed by the molten metal to the safety of the operator.

[0040] Reference Figure 2The first roller 21 can move along the length direction of the chute 11, and the bottom wall of the support platform 1 is rotatably connected to the second roller 12, which is used to drive the support platform 1 to move along the width direction of the chute 11. The moving direction of the second roller 12 is perpendicular to the moving direction of the first roller 21, so that the bracket 2 can move in the left and right direction, and at the same time, the bracket 2 can move in the front and back direction, so that the bracket 2 can move closer to the melting furnace more conveniently.

[0041] Reference Figure 7 The driving shaft of the linear actuator 3 is composed of a supporting shaft 31 and a connecting shaft 32. The supporting shaft 31 is slidably connected to the linear actuator 3. The connecting shaft 32 is hinged to the feeding shell 22. A buffer mechanism 7 is arranged between the supporting shaft 31 and the connecting shaft 32. The buffer mechanism 7 includes a supporting shell 71, a first spring 72, a piston rod 73 and a second spring 74. The supporting shell 71 is arranged between the supporting shaft 31 and the connecting shaft 32, and the supporting shell 71 is fixedly connected to the supporting shaft 31. The piston rod 73 is slidably arranged in the supporting shell 71, and the end of the piston rod 73 away from the supporting shaft 31 is fixedly connected to the connecting shaft 32. A limiting ring 731 is fixedly sleeved on the outer side surface of the piston rod 73. The first spring 72 is arranged between the inner bottom surface of the supporting shell 71 and the limiting ring 731. The second spring 74 is arranged between the inner top surface of the supporting shell 71 and the limiting ring 731.

[0042] The vibration source 4 is activated to transmit the vibration energy to the feeding shell 22. The piston rod 73 can move along the axial direction of the support shell 71 to provide a margin for the feeding shell 22 to move up and down. With the expansion and contraction of the first spring 72 and the second spring 74, the feeding shell 22 can reciprocate in the vertical direction under the action of the vibration source 4. The hopper 5 moves synchronously with the feeding shell 22, thereby increasing the vertical movement amplitude of the ingredients and improving the feeding effect on the melting furnace. In addition, the first spring 72 and the second spring 74 buffer the vibration energy transmitted to the support platform 1 and the bracket 2, thereby improving the stability of the bracket 2 moving along the slide 11.

[0043] Reference Figure 2 and Figure 8 There are four first rollers 21, and a first connecting rod 211 is fixedly connected between every two coaxially arranged first rollers 21, and a transmission worm gear 212 is fixedly sleeved on the outer side of one of the first connecting rods 211. The bottom surface of the bracket 2 is fixedly connected to the second rotation source 8, and the driving shaft of the second rotation source 8 is fixedly connected to a transmission worm 81 meshing with the transmission worm gear 212. The second rotation source 8 drives the first roller 21 to rotate through the transmission worm 81, the transmission worm gear 212 and the first connecting rod 211 in sequence.

[0044] Reference Figure 2 and Figure 8There are four second rollers 12, and a second connecting rod 121 is fixedly connected between every two coaxially arranged second rollers 12. A third rotation source 9 is fixedly connected to the bottom surface of the support platform 1, and the third rotation source 9 is used to drive a second connecting rod 121 to rotate, thereby driving the second roller 12 to rotate.

[0045] The implementation principle of a batching and conveying device according to an embodiment of the present invention is as follows: the second rotating source 8 and the third rotating source 9 move the hopper 5 to the melting furnace. The first rotating source 6 drives the transmission screw 61 to rotate, thereby moving the hopper 5 out of the loading shell 22 and moving the hopper 5 closer to the melting furnace. The reset spring drives the hopper 5 to rotate forward, so that the feed plate 52 opens the discharge port 51. At the same time, the linear drive 3 drives the hopper 5 to tilt, and the vibration source 4 is started, so that the batching falls to the melting furnace through the discharge port 51. After the loading is completed, the first rotating source 6 reverses to make the hopper 5 enter the loading shell 22. The loading shell 22 squeezes the feed plate 52, so that the feed plate 52 reverses and closes the discharge port 51. At the same time, the feed plate 52 moves synchronously with the hopper 5 into the loading shell 22.

[0046] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
