Description

Technical Field

[0001] The present invention relates to the field of waste iron recycling and smelting, and particularly to an efficient waste iron recycling and processing device. Background Art

[0002] With the development and progress of society, the replacement of old and new structures, and the oxidation of iron materials, a large amount of waste iron is generated every year in society. To avoid waste of waste iron resources, it is necessary to recycle and process waste iron. In the prior art, the recycled waste iron is usually reduced and melted into molten iron, and then reprocessed to complete the recycling and reuse of waste iron.

[0003] When recycling and smelting waste iron, in order to improve the smelting efficiency of waste iron in an electric furnace, the waste iron is usually crushed in advance. By rotating the crushing rollers, the waste iron is cut into small pieces, which is convenient for the waste iron to be quickly smelted in the electric furnace. However, the recycled waste iron usually contains some waste iron with relatively large volumes. These large pieces of waste iron have a firm structure and are relatively tightly connected as a whole. If they are directly put into the electric furnace without prior treatment, the smelting efficiency of the large pieces of waste iron in the electric furnace will be low. If they are processed by the crushing rollers, affected by the thickness and size of the large pieces of waste iron, the efficiency of crushing them by the crushing rollers is low, and they are easily blocked at the crushing rollers, thereby reducing the efficiency of transporting the waste iron to the electric furnace and affecting the overall efficiency of waste iron recycling and processing.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the first electric conveyor belt and the second electric conveyor belt are provided to convey scrap iron and large pieces of scrap iron respectively, and the drilling mechanism is arranged between the second electric conveyor belt and the first electric conveyor belt, so that the treatment of large pieces of scrap iron will not interfere with the conveying of scrap iron, ensuring the stability of the scrap iron conveyed into the furnace body.

With the mutual cooperation, the efficiency of scrap iron recycling and treatment can be effectively improved;

[0019] 2. In the present invention, by setting the track as an annular structure, the electric trolley can drive the furnace body to move cyclically between the ironmaking area and the blanking rack. A plurality of ironmaking mechanisms are arranged in the ironmaking area, and the scrap iron in a plurality of furnace bodies can be reduced and smelted at the same time. And when the scrap iron is smelted, the vacant furnace body is loaded with scrap iron, so that the ironmaking mechanism can operate continuously without interruption, avoiding the occupation of ironmaking time by scrap iron loading, which is beneficial to further improving the efficiency of the device for scrap iron recycling and smelting;

[0020] 3. In the present invention, by installing a weighing sensor between the blanking hopper and the blanking rack, and controlling the opening and closing of the bottom plate with the aid of a first electric push rod, the weight of the scrap iron dropped into the furnace body can be controlled, which is conducive to more precisely controlling the quantity of the scrap iron filled in the furnace body, enabling the quantity of the scrap iron filled in the furnace body to match the operating power of the electrode, facilitating the control of the device to smelt the scrap iron in an optimal state, and thus being conducive to improving the efficiency and effect of the device for recycling and processing the scrap iron;

[0021] 4. In the present invention, by arranging a plurality of discs in a stepped structure stacked layer by layer, the range of action of each cutting edge on the scrap iron can be reduced. Compared with directly performing a large-range cutting operation with large-sized cutting edges on the same plane, the stability and efficiency during drilling and cutting can be effectively improved, and it is conducive to extending the service life of the inner cutting edges of the milling cutter, effectively reducing the probability of the cutting edges breaking and chipping;

[0022] 5. In the present invention, by arranging the side plate at the right end position of the second electric conveyor belt, and pushing the push plate with the aid of a fourth electric push rod to push the large pieces of scrap iron within the range covered by the side plate into the drilling mechanism for processing together, it can prevent the continuous conveyance of large pieces of scrap iron by the second electric conveyor belt from affecting the drilling mechanism.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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.

[0042] Embodiment: This embodiment provides a waste iron efficient recycling and processing device. Refer to Figure 1 - Figure 10, specifically, it includes a iron-smelting area 1. At the bottom of the iron-smelting area 1, there is a track 101 extending to the outside, and an electric trolley 102 is slidably installed on the track 101. A furnace body 103 is stacked on the electric trolley 102. An iron-smelting mechanism 2 corresponding to the furnace body 103 is installed in the iron-smelting area 1. A feeding rack 3 is arranged outside the iron-smelting area 1, and a feeding hopper 301 located above the track 101 is installed on the feeding rack 3. A first support 4 is fixedly installed outside the feeding rack 3, and a first electric conveyor belt 401 extending to the top of the feeding hopper 301 is installed on the first support 4. A second electric conveyor belt 403 parallel to the first electric conveyor belt 401 is installed behind the first support 4, and the second electric conveyor belt 403 is located above the first electric conveyor belt 401. A drilling mechanism is installed between the end of the second electric conveyor belt 403 and the first electric conveyor belt 401. The drilling mechanism includes a second support 5 fixedly connected to the first support 4. On the front right side of the second electric conveyor belt 403, there is a housing 501 fixedly installed inside the second support 5, and the housing 501 is located directly above the first electric conveyor belt 401. A pallet 502 flush with the top of the second electric conveyor belt 403 is rotatably installed inside the housing 501. A second electric push rod 503 is rotatably installed on the second support 5, and the telescopic end of the second electric push rod 503 is hinged to the pallet 502. A third electric push rod 504 vertically arranged is fixedly installed on the top of the second support 5, and a bearing platform 505 is fixedly installed on the telescopic end below the third electric push rod 504. A plurality of uniformly distributed clamping heads 506 are rotatably installed at the bottom of the bearing platform 505, and a vertical milling cutter 507 is firmly clamped on each clamping head 506.

[0043] During the use of this device, the waste iron collected by recycling will be pre-screened to separate the large pieces of waste iron, iron bars, and small iron blocks in the waste iron. During recycling production, the furnace body 103 is stacked on the electric trolley 102. A driving unit is arranged inside the electric trolley 102, which can drive the electric trolley 102 to move along the track 101. Driven by the electric trolley 102, the furnace body 103 stacked on the electric trolley 102 moves to the inside of the feeding rack 3, so that the furnace body 103 is directly below the feeding hopper 301. Subsequently, waste iron scraps such as iron bars and small iron blocks are directly conveyed to the feeding hopper 301 through the first electric conveyor belt 401, and fall into the furnace body 103 below with the guidance of the feeding hopper 301. The large pieces of waste iron are conveyed through the second electric conveyor belt 403.

[0044] When the large piece of scrap iron is conveyed to the end position of the second electric conveyor belt 403, it will be transferred into the housing 501. The large piece of scrap iron is laid flat on the top of the pallet 502. Subsequently, the third electric push rod 504 installed on the top of the second bracket 5 is powered on and starts to drive the bearing platform 505 to move downward. A power unit for driving each clamping head 506 to rotate is installed in the bearing platform 505. During the downward movement of the bearing platform 505, the clamping head 506 drives the milling cutter 507 to rotate at a high speed and acts on the large piece of scrap iron. The milling cutter 507 rotates at a high speed to perform a cutting operation on the large piece of scrap iron, forming uniformly distributed through holes in the large piece of scrap iron. The metal chips generated by the cutting accumulate on the pallet 502. When the through holes on the large piece of scrap iron are opened, the third electric push rod 504 starts in the reverse direction, driving the bearing platform 505 to move upward and reset. Synchronously, the milling cutter 507 is moved away from the large piece of scrap iron on the pallet 502. Subsequently, the second electric push rod 503 is powered on and starts to pull the pallet 502 to deflect, causing one end of the pallet 502, which was originally in a horizontal state, to tilt downward, pouring the large piece of scrap iron and metal chips on the pallet 502 onto the first electric conveyor belt 401. Under the conveyance of the first electric conveyor belt 401, they are sent into the feeding hopper 301 and finally put into the furnace body 103 below.

[0045] When the addition of scrap iron in the furnace body 103 is completed, the electric trolley 102 moves along the track 101, sends the furnace body 103 into the iron smelting area 1, and docks with the iron smelting mechanism 2. Through the cooperation of the iron smelting mechanism 2 and the furnace body 103, the scrap iron is reduced and melted into molten iron. After the scrap iron smelting is completed, the electric trolley 102 continues to move along the track 101, removing the furnace body 103 from the other end of the iron smelting area 1. At this time, the staff can lift the furnace body 103 through the hoisting device in the workshop to perform subsequent operations of collecting molten iron and dumping slag. During the use of this device, the collected scrap iron is pre-screened in advance. The scrap iron fragments are conveyed by the first electric conveyor belt 401, and the large pieces of scrap iron are conveyed by the first guard plate 402. In cooperation with the drilling mechanism arranged between the first guard plate 402 and the first electric conveyor belt 401, the large pieces of scrap iron are pre-treated. With the high-speed rotation of numerous uniformly distributed milling cutters 507, dense through holes are formed on the large pieces of scrap iron. By opening the holes, the integrity of the large pieces of scrap iron is damaged, making it easier to be melted and reduced to molten iron, thereby improving the efficiency of the reduction smelting of the recycled scrap iron in the furnace body 103 to a certain extent.

[0046] In the specific implementation process, such as Figure 1 - Figure 3As shown in the figure, there are multiple iron-smelting mechanisms 2, and the multiple iron-smelting mechanisms 2 are sequentially installed in the iron-smelting area 1 along the track 101. The iron-smelting mechanism 2 includes a frame 201 vertically erected outside the track 101, and a first lifting unit 202 is slidably installed on the frame 201. A furnace cover 203 adapted to the top opening of the furnace body 103 is fixedly connected to the first lifting unit 202. A second lifting unit 204 is slidably installed on the frame 201 above the first lifting unit 202, and an electrode 205 vertically arranged above the furnace cover 203 is fixedly installed on the second lifting unit 204. The track 101 is arranged in a ring structure and the track 101 surrounds and penetrates between the blanking rack 3 and the multiple iron-smelting mechanisms 2 in the iron-smelting area 1.

[0047] When the device is in use, by setting the track 101 in a ring structure, the electric trolley 102 can drive the furnace body 103 to move cyclically between the iron-smelting area 1 and the blanking rack 3. Sufficient space is reserved between the entrance of the iron-smelting area 1 and the blanking rack 3, and between the exit of the iron-smelting area 1 and the blanking rack 3. Multiple electric trolleys 102 can be parked on the track 101 in this area. The electric trolley 102 carries the furnace body 103 to the bottom of the blanking rack 3 to load scrap iron. After the scrap iron is loaded, the electric trolley 102 carries the furnace body 103 to move in front of the entrance of the iron-smelting area 1 and waits for the smelting of scrap iron. There are multiple iron-smelting mechanisms 2 in the iron-smelting area 1, which can simultaneously carry out reduction smelting on the scrap iron in multiple furnace bodies 103. During the smelting of scrap iron, the remaining empty furnace bodies 103 are loaded with scrap iron, so that the iron-smelting mechanism 2 can operate continuously without interruption, avoiding the occupation of iron-smelting time by scrap iron loading, and improving the efficiency of scrap iron recycling and smelting of the device to a certain extent.

[0048] The furnace body 103 loaded with scrap iron is moved into the frame 201 under the transportation of the electric trolley 102. In this state, the furnace body 103 is aligned directly below the furnace cover 203. Subsequently, the first lifting unit 202 is powered on and started to drive the furnace cover 203 to move downward to cover the top of the furnace body 103 and block the opening at the top of the furnace body 103. An opening adapted to the electrode 205 is provided at the middle position of the furnace cover 203. The second lifting unit 204 drives the electrode 205 to move downward, passes through the opening on the furnace cover 203 and is vertically inserted into the furnace body 103. Subsequently, the electrode 205 is powered on and started to release a high-temperature arc in the furnace body 103, and directly carry out a reduction operation on the scrap iron in the furnace body 103 by means of the high temperature released by the arc. During the reduction smelting of the scrap iron, the thinner and finer scrap iron fragments will be reduced to molten iron first. These high-temperature molten irons flow in the through holes opened in the large pieces of scrap iron, which can effectively improve the heat uniformity and heat efficiency of the large pieces of scrap iron during subsequent melting, and is beneficial to improving the reduction and melting efficiency of the large pieces of scrap iron.

[0049] After the scrap iron smelting is completed, the second lifting unit 204 drives the electrode 205 to lift upward, and the first lifting unit 202 drives the furnace cover 203 to rise. The furnace body 103 loaded with high-temperature molten iron is transported by the electric trolley 102 and moved out along the track 101. Subsequently, the staff will lift out the furnace body 103 loaded with high-temperature molten iron and lift the empty furnace body 103 onto the electric trolley 102. During the process of the electric trolley 102 moving around along the track 101, a new round of scrap iron smelting is carried out.

[0050] In the specific implementation process, as Figure 4 and Figure 5 shown, the bottom of the feeding hopper 301 is set as an inverted trapezoidal structure. Two symmetrically arranged bottom plates 302 are rotatably installed at the bottom of the feeding hopper 301. Two symmetrically arranged first electric push rods 303 are rotatably installed on the outer end wall of the feeding hopper 301, and the telescopic ends of the first electric push rods 303 are hinged to the corresponding bottom plates 302. The feeding hopper 301 is vertically slidably installed on the feeding frame 3. A spring for elastically supporting the feeding hopper 301 is installed at the connection between the feeding frame 3 and the feeding hopper 301. A weighing sensor acting on the feeding hopper 301 is installed on the feeding frame 3. During the use of this device, by setting the bottom of the feeding hopper 301 as an inverted trapezoidal structure, the scrap iron can be gathered during the dropping process of the scrap iron, which is beneficial to ensuring the stability of guiding the scrap iron into the furnace body 103 through the feeding hopper 301. At the same time, by installing the weighing sensor between the feeding hopper 301 and the feeding frame 3 and controlling the opening and closing of the bottom plate 302 by means of the first electric push rod 303, the weight of the scrap iron dropped into the furnace body 103 can be controlled, which is beneficial to more accurately controlling the quantity of the scrap iron loaded in the furnace body 103, making the quantity of the scrap iron filled in the furnace body 103 match the operating power of the electrode 205, facilitating the control of the device to carry out the smelting of scrap iron in the optimal state, and thus effectively improving the efficiency of the device for recycling and processing scrap iron.

[0051] In the specific implementation process, as Figure 7 and Figure 8As shown, the pallet 502 is provided with leakage holes 508 that penetrate through and correspond one by one to a plurality of milling cutters 507, and the inner diameter of the leakage holes 508 is set to 1.5 times the outer diameter of the milling cutters 507. During the use of the device, by providing the leakage holes 508 corresponding one by one to the milling cutters 507 on the pallet 502 and setting the inner diameter of the leakage holes 508 to 1.5 times the outer diameter of the milling cutters 507, when the milling cutters 507 rotate at high speed to drill through large pieces of scrap iron, the milling cutters 507 can enter the corresponding leakage holes 508 below, and the cutting of the milling cutters 507 will not act on the pallet 502. At the same time, due to the existence of the leakage holes 508, the metal chips or metal wire strips generated by cutting can directly fall onto the first electric conveyor belt 401 below the housing 501 through the leakage holes 508, avoiding the accumulation of metal chips from affecting the upward movement and reset of the milling cutters 507, which is beneficial to ensuring the stability during the actual operation of the drilling mechanism.

[0052] During the specific implementation process, as Figure 9 and Figure 10 shown, the milling cutter �07 includes a connecting rod 5071 firmly clamped in the clamping head 506, and a plurality of coaxially arranged discs 5072 are fixedly installed at the bottom end of the connecting rod 5071 from top to bottom. The outer diameters of the plurality of discs 5072 from top to bottom gradually decrease, and the outer diameter of the upper disc 5072 is set to 2 times the outer diameter of the lower disc 5072. A cutting edge 5073 is fixedly installed at the bottom of each disc 5072, and a chip discharge hole 5074 penetrates through each disc 5072. The plurality of cutting edges 5073 are distributed in a spiral structure at the bottom of the plurality of discs 5072 from top to bottom.

[0053] During the use of the device, the clamping head 506 drives the connecting rod �071 to rotate at high speed, and then drives the plurality of discs 5072 fixed at the lower end to rotate synchronously at high speed. During the high-speed rotation of each disc 5072, the cutting edge 5073 fixed at its bottom acts on the scrap iron to perform a cutting operation on the scrap iron. Along with the downward movement of the milling cutter 507, a through hole is finally formed in the large piece of scrap iron. By setting the plurality of discs 5072 as a stepped structure stacked layer by layer, during the cutting process, the range of action of the cutting edge 5073 at the bottom of each disc 5072 can be reduced. Compared with directly performing a large-range cutting operation using the cutting edges 5073 in the same plane, the milling cutter 507 in this application can effectively improve the stability and efficiency during drilling and cutting, and is beneficial to extending the service life of the cutting edge 5073 inside the milling cutter 507 and reducing the probability of the cutting edge 5073 breaking and crumbling.

[0054] During the use of the device, when the milling cutter 507 rotates at a high speed for cutting, the chip discharge holes 5074 penetrating through the disc 5072 can assist in discharging the metal chips generated by cutting outward, avoiding the accumulation of metal chips generated by cutting in the holes. At the same time, by arranging the cutting edges 5073 at the bottom of multiple discs 5072 in a spiral shape, the positions where the cutting edges 5073 at the bottom of each disc 5072 act on the scrap iron can be dispersed, avoiding the accumulation of metal chips generated by cutting at the same position in the holes. With the above structures cooperating with each other, it is beneficial to ensure the high-efficiency and stability of discharging metal debris outward, and thus improves the stability of the device to a certain extent when cutting and drilling large pieces of scrap iron.

[0055] In the specific implementation process, as Figure 6 shown, a first guard plate 402 is fixedly installed on the first support 4 on the front and rear sides of the first electric conveyor belt 401, a second guard plate 404 is fixedly installed on the first support 4 on the front and rear sides of the second electric conveyor belt 403. A side plate 6 fixedly connected to the rear second guard plate 404 is arranged at the right end of the second electric conveyor belt 403, and a longitudinally arranged fourth electric push rod 601 is fixedly installed behind the side plate 6. A push plate 602 fixedly connected to the telescopic end of the fourth electric push rod 601 is arranged inside the side plate 6, and the size of the push plate 602 is adapted to the internal size of the housing 501. A longitudinally arranged baffle 603 is slidably installed at the connection between the rear second guard plate 404 and the side plate 6, and the front end of the baffle 603 is fixedly connected to the left end of the push plate 602. The push plate 602 and the baffle 603 cooperate to form an L-shaped structure.

[0056] During the use of the device, when a large piece of scrap iron is conveyed to the right end of the second electric conveyor belt 403, the large piece of scrap iron enters the range corresponding to the side plate 6. The range where the side plate 6 covers the second electric conveyor belt 403 is adapted to the space for processing large pieces of scrap iron inside the housing 501. The fourth electric push rod 601 installed on the back of the side plate 6 is powered on and starts, and its telescopic end pushes the push plate 602 to move into the housing 501, pushing the large piece of scrap iron on the second electric conveyor belt 403 that enters the range covered by the side plate 6 onto the pallet 502 inside the housing 501. Subsequently, drilling treatment is carried out by the milling cutter 507. When the push plate 602 pushes the large piece of scrap iron onto the pallet 502, it will drive the baffle 603 to move forward synchronously, forming a shield on the left side of the push plate 602 to block the left end of the range covered by the side plate 6 on the second electric conveyor belt 403, avoiding the scrap iron from entering between the fourth electric push rod 601 and the push plate 602, which is beneficial to ensuring the stability during the actual use of the device. When the drilling mechanism processes the large piece of scrap iron, the telescopic end of the fourth electric push rod 601 retracts, driving the push plate 602 to move backward and reset. At this time, the large pieces of scrap iron conveyed on the second electric conveyor belt 403 can continue to enter the range covered by the side plate 6 to prepare for the planing and drilling treatment of the next batch of large pieces of scrap iron.

[0057] During the use of the device, by setting the side plate 6 at the right end of the second electric conveyor belt 403 and using the fourth electric push rod 601 to push the push plate 602, the large pieces of scrap iron within the coverage of the side plate 6 are pushed into the drilling mechanism for processing together. Compared with directly connecting the drilling mechanism in the conveying direction at the right end of the second electric conveyor belt 403, it can effectively reduce the impact of the continuous conveyance of large pieces of scrap iron by the second electric conveyor belt 403 on the drilling mechanism during the operation of the drilling mechanism. At the same time, it can also significantly reduce the feeding time of the drilling mechanism, compressing the process of large pieces of scrap iron entering the drilling mechanism into the instantaneous push of the push plate 602, which improves the efficiency of the device during processing to a certain extent.

[0058] Specifically, the working principle and operation method of the present invention are as follows:

[0059] The staff screens out the large pieces of scrap iron from the scrap iron, conveys the scrap iron fragments to the feeding hopper 301 through the first electric conveyor belt 401, conveys the large pieces of scrap iron to the coverage area of the side plate 6 through the second electric conveyor belt 403. Subsequently, the fourth electric push rod 601 is powered on and starts to drive the push plate 602 to move, pushing the large pieces of scrap iron within the coverage area of the side plate 6 onto the support plate 502 inside the outer shell 501. After the third electric push rod 504 is powered on and starts to drive the bearing platform 505 to move downward, the power unit inside the bearing platform 505 drives the milling cutter 507 clamped inside the clamping head 506 to rotate at high speed. During the downward movement, the large pieces of scrap iron are cut and perforated, forming numerous uniformly distributed through holes on the large pieces of scrap iron. After the cutting and drilling are completed, the third electric push rod 504 retracts to drive the milling cutter 507 to move upward and reset. The second electric push rod 503 pulls the support plate 502 to tilt downward, dumping the perforated large pieces of scrap iron and metal chips onto the first electric conveyor belt 401 and conveying them into the feeding hopper 301. After weighing, they are quantitatively released into the furnace body 103 through the opening and closing of the bottom plate 302. The electric trolley 102 carries the furnace body 103 into the ironmaking area 1 and docks with the ironmaking mechanism 2. Then, the furnace cover 203 covers the furnace body 103, the electrode 205 is inserted into the furnace body 103, and the electrode 205 is started to reduce and smelt the scrap iron inside the furnace body 103. After the scrap iron smelting is completed, the ironmaking mechanism 2 returns to the initial state, and the electric trolley 102 carries the furnace body 103 out of the ironmaking area 1 for subsequent processing.

[0060] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
