Description

Technical Field

[0001] This utility model relates to the field of metal smelting, and in particular to a feeding device for ferrous metal smelting. Background Technology

[0002] Ferrous metal smelting refers to the process of converting raw materials such as iron ore into iron or ferroalloys (such as steel and cast iron) through smelting techniques. Ferrous metals usually refer to iron and its alloys, because iron is the main representative element of the ferrous metal family.

[0003] Metal smelting feeding refers to the operation of feeding raw materials (metal ores, alloying elements, etc.) into a smelting furnace for smelting. This process typically involves feeding raw materials into the furnace, or adding prepared metal or alloy materials to the furnace to initiate the smelting process. In some smelting processes, attention must be paid to the order and amount of feeding to ensure uniform smelting and the quality of the final product.

[0004] Metal smelting feeding generally refers to the input or addition of raw materials (such as ores, scrap metal, alloying elements, etc.) during the metal smelting process. This process is a key step in smelting operations, typically involving placing raw materials into the smelting furnace in appropriate proportions and sequences for melting, chemical reactions, or other processing. The types and methods of feeding vary depending on the specific smelting process.

[0005] In practical applications, existing ferrous metal ores, due to their varying particle sizes, are prone to uneven smelting during the feeding process, leading to incomplete reactions within the furnace. Furthermore, the presence of metal powder mixed with the ferrous metal ore in a timely manner reduces smelting efficiency. Therefore, this paper proposes a ferrous metal smelting feeding device to address these issues. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a ferrous metal smelting feeding device, which realizes the crushing treatment of ferrous metal ore by setting a crushing component, thereby facilitating full smelting, and improves the smelting uniformity by setting a screen to screen the powder of ferrous metal ore.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A ferrous metal smelting feeding device includes a support frame, and a metal ore crushing component is assembled on the upper end face of the support frame.

[0009] A feeding platform is mounted on the side of the support frame, and a stirring assembly is mounted on the upper surface of the feeding platform. The metal ore crushing assembly is mounted above the stirring assembly and is connected to the stirring assembly.

[0010] The side of the unloading platform is provided with a conveyor belt unloading mechanism, and the side of the conveyor belt unloading mechanism is equipped with the body of a ferrous metal ore smelting furnace.

[0011] The metal ore crushing assembly includes a base disposed on the side of the support frame. A carrying bucket is installed on the upper surface of the base. The carrying bucket is bucket-shaped and has a slot at its bottom. Two transmission rods are rotatably disposed inside the carrying bucket. Several crushing teeth are sleeved on the outside of the two transmission rods. The several crushing teeth on the two transmission rods are arranged in an alternating manner.

[0012] The upper surface of the feeding platform is provided with a feeding hopper, which is shaped like a bucket. The stirring assembly includes an ore receiving hopper provided on the upper surface of the feeding hopper, and a feeding cylinder is connected to the bottom of the ore receiving hopper. A supporting beam is installed on the ore receiving hopper, which is L-shaped and has a rotating rod rotatably installed on its vertical end. A stirring blade is sleeved on the outside of the rotating rod.

[0013] The unloading platform is a rectangular hollow box. An inclined slot is opened on one side of the unloading platform, and an unloading seat is inclinedly slidably arranged inside it. A screen is provided at the bottom of the unloading seat.

[0014] Furthermore, the stirring blade passes through the ore receiving hopper and extends into the feeding cylinder; the feeding cylinder is cylindrical with openings on both sides, and is located inside and connected to the feeding hopper.

[0015] Furthermore, the upper surface of the screen is open and slides on the lower surface of the feed cylinder, and the screen has a plurality of holes.

[0016] Furthermore, the bottom of the unloading platform is provided with a chute and a debris collection box is movably arranged in the chute. The debris collection box is located below the unloading base and the upper surface of the debris collection box is open.

[0017] Furthermore, the metal ore crushing assembly also includes a reduction motor disposed on the upper surface of the base, the output end of which passes through the bearing bucket and extends to connect with the end of one of the transmission rods.

[0018] Furthermore, the stirring assembly also includes a second reduction motor disposed on the upper end face of the supporting beam, and the output end of the second reduction motor is connected to the rotating rod.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In practical use, the interaction of multiple structures set in the metal ore crushing component allows several rotating crushing teeth to squeeze and crush the ferrous metal ore. The metal ore crushing component makes the ferrous metal ore particles uniform, ensuring that the ore can fully react during the smelting process, thereby promoting the reduction reaction and improving the smelting efficiency.

[0021] 2. After the metal ore crushing component crushes the metal ore, the stirring component located below the metal ore crushing component can ensure that the ferrous metal ore falls evenly during the feeding process and enters the feeding platform, avoiding excessive metal ore falling at one time, thereby preventing blockage in the feeding platform. Finally, the ferrous metal ore can pass through the feeding platform at a uniform speed and enter the conveyor belt feeding mechanism to complete the feeding operation.

[0022] 3. Through the combination of the feeding seat and screen installed within the feeding platform, after the ferrous metal ore is crushed and enters the platform, the feeding seat effectively separates metal dust and excessively small metal fragments from the ore. This prevents dust and fragments from escaping with the flue gas during subsequent smelting, thus avoiding waste of raw materials. These dust and fragments can be collected in a fragment collection box. The inclined feeding seat further reduces interference from impurities, thereby improving smelting efficiency, ensuring a more efficient smelting process, and minimizing incomplete reactions during smelting.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0031] First embodiment;

[0032] Reference Figure 1-5 As shown, a preferred embodiment of the present invention is a ferrous metal smelting feeding device, which includes a support frame 1 and a metal ore crushing component 2 assembled on the upper end face of the support frame 1.

[0033] A feeding platform 3 is mounted on the side of the support frame 1, and a mixing component 4 is mounted on the upper surface of the feeding platform 3. The metal ore crushing component 2 is mounted above the mixing component 4 and connected to the mixing component 4.

[0034] A conveyor belt feeding mechanism 5 is provided on the side of the feeding platform 3, and a ferrous metal ore smelting furnace body 6 is mounted on the side of the conveyor belt feeding mechanism 5.

[0035] The metal ore crushing assembly 2 includes a base 21 disposed on the side of the support frame 1. A bearing bucket 22 is installed on the upper surface of the base 21. The bearing bucket 22 is bucket-shaped and has a slot at its bottom. Two transmission rods 23 are rotatably disposed inside the bearing bucket 22. Several crushing teeth 24 are sleeved on the outside of the two transmission rods 23. The several crushing teeth 24 on the two transmission rods 23 are arranged in an alternating manner.

[0036] The upper surface of the feeding platform 3 is provided with a feeding hopper 31, which is shaped like a bucket. The stirring assembly 4 includes an ore receiving hopper 41 located on the upper surface of the feeding hopper 31. The bottom of the ore receiving hopper 41 is connected to a feeding cylinder 42. A bearing beam 43 is installed on the ore receiving hopper 41. The bearing beam 43 is L-shaped and a rotating rod 44 is rotatably mounted on its vertical end. A stirring blade 45 is sleeved on the outside of the rotating rod 44.

[0037] The unloading platform 3 is a rectangular hollow box. An inclined slot is opened on one side of the unloading platform 3, and an unloading seat 32 is inclined and slidably installed inside it. A screen 321 is installed at the bottom of the unloading seat 32.

[0038] In this embodiment, through the mutual cooperation of multiple structures arranged in the metal ore crushing component 2, several crushing teeth 24 that rotate relative to each other can squeeze and crush the ferrous metal ore. The metal ore crushing component 2 makes the ferrous metal ore particles uniform, ensuring that the ore can fully react during the smelting process, thereby promoting the reduction reaction and improving the smelting efficiency.

[0039] Second embodiment;

[0040] Reference Figure 5 As shown, the stirring blade 45 passes through the ore receiving hopper 41 and extends into the feeding cylinder 42; the feeding cylinder 42 is cylindrical with openings on both sides, and is located inside and connected to the feeding hopper 31. When the rotating rod 44 rotates, the stirring blade 45, which is sleeved on the outside of the rotating rod 44, will rotate accordingly, thereby stirring the falling ferrous metal ore. At this time, the metal ore will pass through the feeding cylinder 42, and the opening of the feeding cylinder 42 allows the ferrous metal ore to fall evenly into the feeding hopper 31.

[0041] After the metal ore crushing component 2 crushes the metal ore, the stirring component 4 located below the metal ore crushing component 2 can ensure that the ferrous metal ore falls evenly during the feeding process and enters the feeding platform 3, avoiding excessive metal ore falling at one time, thereby preventing blockage of the metal ore in the feeding platform 3, and finally allowing the ferrous metal ore to pass through the feeding platform 3 at a uniform speed to complete the feeding operation.

[0042] Third embodiment;

[0043] Reference Figure 1-3 As shown, the upper end face of the screen 321 is open and it slides on the lower end face of the feed cylinder 42. The screen 321 has several holes. Through the screening of the screen 321 set at the bottom of the feed base 32, the dust and small debris in the ferrous metal ore will pass through the holes of the screen 321. By utilizing the setting of the feed base 32, the ferrous metal ore can be sorted.

[0044] By combining the feeding seat 32 and the screen 321 within the feeding platform 3, after the ferrous metal ore is crushed and enters the feeding platform 3, the feeding seat 32 effectively separates the metal dust and excessively small metal fragments from the ore. This prevents the dust and fragments from escaping with the flue gas during subsequent smelting processes, thus avoiding waste of metal raw materials. The dust and fragments can be collected by the fragment collection box 33. The inclined feeding seat 32 further reduces interference from impurities, thereby improving smelting efficiency, ensuring a more efficient smelting process, and reducing incomplete reactions during smelting.

[0045] Fourth embodiment;

[0046] Reference Figure 1 and Figure 3 As shown, the bottom of the feeding platform 3 is provided with a chute, and a debris collection box 33 is movably installed in the chute. The debris collection box 33 is located below the feeding seat 32, and the upper surface of the debris collection box 33 is open. When the crushed ferrous metal ore falls into the feeding hopper 31, the feeding seat 32, which is inclined and installed in the feeding hopper 31, can support the ferrous metal ore. Through the screening of the screen 321 at the bottom of the feeding seat 32, the dust and small debris in the ferrous metal ore will pass through the holes of the screen 321 and fall into the debris collection box 33 for collection.

[0047] Fifth embodiment;

[0048] Reference Figure 4 As shown, the metal ore crushing assembly 2 also includes a reduction motor 25 disposed on the upper surface of the base 21. The output end of the reduction motor 25 passes through the bearing hopper 22 and extends to connect with the end of one of the transmission rods 23. The reduction motor 25 can be used to drive the transmission rod 23 to rotate. When one of the transmission rods 23 is driven and rotates actively, it is subjected to the staggered arrangement of several crushing teeth 24 and the compression of ferrous metal ore, so that the two transmission rods 23 can maintain synchronous opposite rotation.

[0049] Sixth embodiment;

[0050] Reference Figure 5As shown, the stirring assembly 4 also includes a second geared motor 46 disposed on the upper end face of the supporting beam 43, and the output end of the second geared motor 46 is connected to the rotating rod 44. The second geared motor 46 can be used to drive the rotating rod 44 to rotate. The second geared motor 46 is connected to a motor controller, which can be used to control the number of rotations and the direction of rotation of the motor. In use, the power supply connection method of the motor is existing technology, and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0051] Furthermore, in order to avoid the impact of falling metal ore on the second geared motor 46, in a preferred embodiment, the falling opening of the carrying bucket 22 is offset from that of the second geared motor 46, and a dust cover is also provided on the outside of the second geared motor 46 to prevent the ore from interfering with the working state of the second geared motor 46.

[0052] Specific implementation process:

[0053] Step 1: When smelting ferrous metal ore, the user first pours the ferrous metal ore into the carrying hopper 22, and then starts the reduction motor 25. At this time, the reduction motor 25 will drive the transmission rod 23 to rotate, thereby driving the crushing teeth 24 to rotate through the transmission rod 23. Driven by the transmission rod 23 and squeezed by the compression of the ferrous metal ore, the two staggered transmission rods 23 will rotate synchronously, thereby crushing the ferrous metal ore.

[0054] Step 2: The ferrous metal ore crushed by the metal ore crushing component 2 will enter the ore receiving hopper 41. At this time, the user connects the second reduction motor 46 to an external power source, so that the second reduction motor 46 can drive the rotating rod 44 to rotate. When the rotating rod 44 rotates, the stirring blade 45 sleeved on the outside of the rotating rod 44 will rotate along with it, thereby stirring the falling ferrous metal ore and making it fall evenly into the feeding hopper 31.

[0055] Step 3: After the crushed ferrous metal ore falls into the hopper 31, the inclined feeding seat 32 inside the hopper 31 supports the ferrous metal ore. The screen 321 at the bottom of the feeding seat 32 filters out dust and small fragments within the ferrous metal ore, allowing them to fall into the fragment collection box 33 for collection. Ferrous metal ore that meets the size requirements can then fall through the feeding seat 32 under gravity into the collection hopper of the conveyor belt feeding mechanism 5. Finally, the conveyor belt feeding mechanism 5 transports the crushed ferrous metal ore into the ferrous metal ore smelting furnace body 6 for smelting. Thus, through the above structural coordination, the ferrous metal ore feeding and smelting operation is finally achieved.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
