Description

Technical Field

[0001] The invention relates to the field of scrap iron recovery and smelting, and in particular to a scrap iron efficient recovery and processing device. Background Art

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

[0003] When recycling and smelting scrap iron, in order to improve the smelting efficiency of scrap iron in the electric furnace, the scrap iron is usually crushed in advance. The scrap iron is cut into small pieces by the rotation of the crushing roller, which is convenient for rapid smelting of the scrap iron in the electric furnace. However, the recycled scrap iron is usually mixed with some larger scrap iron. These large pieces of scrap iron have a firm structure and are relatively tightly connected as a whole. If they are not processed in advance and are directly put into the electric furnace, the smelting efficiency of the large pieces of scrap iron in the electric furnace will be low. If they are processed by crushing rollers, the thickness and size of the large pieces of scrap iron will affect their efficiency in being crushed by the crushing rollers, and they are easily blocked at the crushing rollers, which in turn reduces the efficiency of conveying the scrap iron to the electric furnace, affecting the overall efficiency of scrap iron recycling.

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Embodiment: This embodiment provides a scrap iron efficient recycling and processing equipment, see Figure 1 - Fig.10Specifically, it includes an ironmaking area 1, a track 101 extending to the outside is installed at the bottom of the ironmaking area 1, and an electric trolley 102 is slidably installed on the track 101, a furnace body 103 is stacked on the electric trolley 102, an ironmaking mechanism 2 corresponding to the furnace body 103 is installed in the ironmaking area 1, a material unloading rack 3 is arranged on the outside of the ironmaking area 1, and a material unloading hopper 301 located above the track 101 is installed on the material unloading rack 3, a first bracket 4 is fixedly installed on the outside of the material unloading rack 3, and a first electric conveyor belt 401 extending to the top of the material unloading hopper 301 is installed on the first bracket 4, a second electric conveyor belt 403 arranged parallel to the first electric conveyor belt 401 is installed behind the first bracket 4, and the second electric conveyor belt 403 is located above the first electric conveyor belt 401, and the end of the second electric conveyor belt 403 is aligned with the first electric conveyor belt 40 1, a drilling mechanism is installed between the two ends of the second bracket 5, and the drilling mechanism includes a second bracket 5 fixedly connected to the first bracket 4, a shell 501 fixedly installed in the second bracket 5 is arranged on the right side of the front of the second electric conveyor belt 403, and the shell 501 is located directly above the first electric conveyor belt 401, a support plate 502 flush with the top of the second electric conveyor belt 403 is rotatably installed in the shell 501, a second electric push rod 503 is rotatably installed on the second bracket 5, and the telescopic end of the second electric push rod 503 is hinged to the support plate 502, a third electric push rod 504 is fixedly installed vertically on the top of the second bracket 5, and a bearing platform 505 is fixedly installed on the telescopic end below the third electric push rod 504, and a plurality of evenly distributed clamping heads 506 are rotatably installed on the bottom of the bearing platform 505, and each clamping head 506 firmly clamps a milling cutter 507 pointing vertically downward.

[0043] During the use of the device, the scrap iron collected by the recycling will be screened in advance, and the large pieces of scrap iron, iron bars and small iron blocks in the scrap iron will be separated. During the recycling production, the furnace body 103 is stacked on the electric trolley 102. The electric trolley 102 is provided with a driving unit, 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 inner side of the unloading rack 3, so that the furnace body 103 is directly below the unloading hopper 301, and then the scrap iron fragments such as iron bars and small iron blocks are directly transported to the unloading hopper 301 through the first electric conveyor belt 401, and fall into the furnace body 103 below with the guidance of the unloading hopper 301, and the large pieces of scrap iron are transported through the second electric conveyor belt 403.

[0044] When the large piece of scrap iron is transported to the end position of the second electric conveyor belt 403, it will be transferred to the shell 501, and the large piece of scrap iron will be laid flat on the top of the support plate 502. Then, the third electric push rod 504 installed on the top of the second bracket 5 is powered on and started, driving the support platform 505 to move downward. A power unit for driving each clamping head 506 to rotate is installed in the support platform 505. During the downward movement of the support platform 505, the clamping head 506 drives the milling cutter 507 to rotate at high speed, acting on the large piece of scrap iron. The milling cutter 507 rotates at high speed to cut the large piece of scrap iron, forming evenly distributed through holes in the large piece of scrap iron, and cutting The generated metal chips are accumulated on the support plate 502. When the through hole on the large piece of scrap iron is opened, the third electric push rod 504 is started in the reverse direction, driving the support platform 505 to move upward and reset, and synchronously, the milling cutter 507 is moved away from the large piece of scrap iron on the support plate 502. Then the second electric push rod 503 is powered on and started, pulling the support plate 502 to deflect, so that one end of the support plate 502, which was originally in a horizontal state, tilts downward, and the large pieces of scrap iron and metal chips on the support plate 502 are dumped onto the first electric conveyor belt 401, and are sent into the lower hopper 301 under the transportation of the first electric conveyor belt 401, and finally put into the furnace body 103 below.

[0045] When the scrap iron in the furnace body 103 is added, the electric trolley 102 moves along the track 101, sends the furnace body 103 into the ironmaking area 1, and docks with the ironmaking mechanism 2. Through the cooperation of the ironmaking mechanism 2 and the furnace body 103, the scrap iron is reduced and smelted into molten iron. After the scrap iron is smelted, the electric trolley 102 continues to move along the track 101 to move the furnace body 103 out of the other end of the ironmaking area 1. At this time, the staff can lift the furnace body 103 through the lifting device in the factory to collect the molten iron and dump the slag. During the use of the device, the collected scrap iron is screened in advance. The scrap iron fragments are transported by the first electric conveyor belt 401, and the large pieces of scrap iron are transported by the first guard plate 402. The large pieces of scrap iron are pre-processed with the help of a drilling mechanism arranged between the first guard plate 402 and the first electric conveyor belt 401. With the help of a large number of evenly distributed milling cutters 507 rotating at high speed, dense through holes are formed on the large pieces of scrap iron. Through the opening of the holes, the overall tightness of the large pieces of scrap iron is destroyed, making it easier to be smelted and reduced to molten iron, thereby improving the efficiency of reduction smelting in the furnace body 103 after the scrap iron is recovered to a certain extent.

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

[0047] When the device is used, the track 101 is set as a ring structure, so that the electric trolley 102 can drive the furnace body 103 to circulate between the ironmaking area 1 and the unloading rack 3. Sufficient space is reserved between the entrance of the ironmaking area 1 and the unloading rack 3, and between the exit of the ironmaking area 1 and the unloading 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 unloading rack 3 for loading of scrap iron. After completion, the electric trolley 102 carries the furnace body 103 to the entrance of the ironmaking area 1, waiting for the smelting of scrap iron. A plurality of ironmaking mechanisms 2 are arranged in the ironmaking area 1, which can simultaneously carry out reduction smelting on the scrap iron in a plurality of furnace bodies 103. When smelting scrap iron, the remaining idle furnace bodies 103 are loaded with scrap iron, so that the ironmaking mechanism 2 can operate continuously and uninterruptedly, avoiding the scrap iron loading occupying the ironmaking time, and improving the efficiency of the device for scrap iron recovery and smelting to a certain extent.

[0048] The furnace body 103 loaded with scrap iron is moved into the frame 201 by the electric trolley 102. In this state, the furnace body 103 is aligned directly below the furnace cover 203. Then the first lifting unit 202 is powered on and started, driving the furnace cover 203 to move downward, covering the top of the furnace body 103, and blocking the opening on the top of the furnace body 103. An opening adapted to the electrode 205 is opened in the middle of the furnace cover 203. The second lifting unit 204 drives the electrode 205 to move downward through the opening on the furnace cover 203. After that, it is vertically inserted into the furnace body 103, and then the electrode 205 is powered on to start, releasing a high-temperature electric arc in the furnace body 103, and using the high temperature when the electric arc is released to directly reduce the scrap iron in the furnace body 103. During the scrap iron reduction smelting process, 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 heating uniformity and heating efficiency of the large pieces of scrap iron during subsequent smelting, and is beneficial to improving the efficiency of the reduction and melting of the large pieces of scrap iron.

[0049] When the scrap iron smelting is completed, the second lifting unit 204 drives the electrode 205 to lift up, and the first lifting unit 202 drives the furnace cover 203 to lift up, and the furnace body 103 loaded with high-temperature molten iron is moved out along the track 101 under the transportation of the electric trolley 102. Subsequent 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. In 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, Figure 4 and Figure 5 As shown, the bottom of the lower hopper 301 is set to an inverted trapezoidal structure, and two symmetrically arranged bottom plates 302 are rotatably installed at the bottom of the lower hopper 301. Two symmetrically arranged first electric push rods 303 are rotatably installed on the outer end wall of the lower hopper 301, and the telescopic ends of the first electric push rods 303 are hinged to the corresponding bottom plates 302. The lower hopper 301 is vertically slidably installed on the lower material rack 3, and a spring for elastically supporting the lower hopper 301 is installed at the connection between the lower material rack 3 and the lower hopper 301. A weighing sensor acting on the lower hopper 301 is installed on the lower material rack 3. During the use of the device, by setting the bottom of the lower hopper 301 to an inverted trapezoidal structure, Gathering the scrap iron during the scrap iron lowering process is beneficial to ensuring the stability of the scrap iron being guided into the furnace body 103 through the lower hopper 301. At the same time, by installing a weighing sensor between the lower hopper 301 and the lower rack 3, and controlling the opening and closing of the bottom plate 302 with the help of the first electric push rod 303, the weight of the scrap iron lowered into the furnace body 103 can be controlled, which is beneficial to more accurately control the amount of scrap iron loaded in the furnace body 103, so that the amount of scrap iron loaded in the furnace body 103 is adapted to the operating power of the electrode 205, which is convenient for controlling the device to smelt scrap iron in the optimal state, thereby effectively improving the efficiency of the device for scrap iron recycling and processing.

[0051] In the specific implementation process, Figure 7 and Figure 8As shown, leakage holes 508 corresponding to a plurality of milling cutters 507 are provided on the support plate 502, and the inner diameter of the leakage hole 508 is set to 1.5 times the outer diameter of the milling cutter 507. During the use of the device, leakage holes 508 corresponding to the milling cutters 507 are provided on the support plate 502, and the inner diameter of the leakage hole 508 is set to 1.5 times the outer diameter of the milling cutter 507, so that when the milling cutter 507 rotates at high speed to drill through a large piece of scrap iron, the milling cutter 507 can enter the corresponding leakage hole 508 below, and the cutting of the milling cutter 507 will not act on the support plate 502. At the same time, due to the existence of the leakage hole 508, the metal chips or metal wire strips produced by the cutting can directly fall through the leakage hole 508 to the first electric conveyor belt 401 below the shell 501, so as to avoid the accumulation of metal chips affecting the upward reset of the milling cutter 507, which is beneficial to ensure the stability of the drilling mechanism during actual operation.

[0052] In the specific implementation process, Fig. 9 and Fig.10 As shown, the milling cutter 507 includes a connecting rod 5071 firmly clamped in the clamping head 506, and a plurality of coaxially arranged discs 5072 are fixedly installed on the bottom end of the connecting rod 5071 from top to bottom, and the outer diameters of the plurality of discs 5072 decrease layer by layer from top to bottom, and the outer diameter of the upper disc 5072 is set to be twice the outer diameter of the lower disc 5072, and a blade 5073 is fixedly installed on the bottom of each disc 5072, and a chip removal hole 5074 is opened through each disc 5072, and the plurality of blades 5073 are distributed in a spiral structure from top to bottom at the bottom of the plurality of discs 5072.

[0053] During the use of the device, the clamping head 506 drives the connecting rod 5071 to rotate at high speed, and then drives the multiple disks 5072 fixed at the lower end to rotate synchronously at high speed. During the high-speed rotation of each disk 5072, the blade 5073 fixed at the bottom acts on the scrap iron to cut the scrap iron. As the milling cutter 507 moves downward, a through hole is finally formed in the large piece of scrap iron. By arranging the multiple disks 5072 into a stepped structure stacked layer by layer, the range of action of the blade 5073 at the bottom of each disk 5072 can be reduced during cutting. Compared with using the blade 5073 on the same plane to directly perform a large-scale cutting operation, the milling cutter 507 in the present application can effectively improve the stability and efficiency during drilling and cutting, and is beneficial to prolonging the service life of the blade 5073 in the milling cutter 507 and reducing the probability of the blade 5073 breaking and breaking.

[0054] During use of the device, when the milling cutter 507 rotates at high speed for cutting processing, the chip discharge holes 5074 formed on the disc 5072 can assist in discharging metal chips generated by cutting to the outside, thereby preventing metal chips generated by cutting from accumulating in the hole. At the same time, by distributing the blades 5073 at the bottom of multiple discs 5072 in a spiral shape, the positions at which the blades 5073 at the bottom of each disc 5072 act on the scrap iron can be dispersed, thereby preventing metal chips generated by cutting from accumulating in the same position in the hole. The above structures cooperate with each other to ensure the efficient and stable discharge of metal debris, thereby improving the stability of the device when cutting and drilling on large pieces of scrap iron to a certain extent.

[0055] In the specific implementation process, Figure 6 As shown, a first guard plate 402 arranged on the front and rear sides of the first electric conveyor belt 401 is fixedly installed on the first bracket 4, a second guard plate 404 arranged on the front and rear sides of the second electric conveyor belt 403 is fixedly installed on the first bracket 4, 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 fourth electric push rod 601 arranged longitudinally is fixedly installed at the rear of the side plate 6, a push plate 602 fixedly connected to the telescopic end of the fourth electric push rod 601 is arranged on the inner side of the side plate 6, and the size of the push plate 602 is adapted to the internal size of the outer shell 501, and a longitudinal 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, and the push plate 602 cooperates with the baffle 603 to form an L-shaped structure.

[0056] During the use of the device, when large pieces of scrap iron are conveyed to the right end of the second electric conveyor belt 403, the large pieces of scrap iron enter the range corresponding to the side plate 6. The range covered by the side plate 6 on the second electric conveyor belt 403 is adapted to the space for processing large pieces of scrap iron in the shell 501. The fourth electric push rod 601 installed on the back of the side plate 6 is powered on and started, and its telescopic end pushes the push plate 602 to move into the shell 501, pushing the large pieces of scrap iron on the second electric conveyor belt 403 that enter the range covered by the side plate 6 onto the support plate 502 in the shell 501, and then drilling is performed by the milling cutter 507. The large pieces of scrap iron are pushed by the push plate 602 When it reaches the support plate 502, it will drive the baffle plate 603 to move forward synchronously, forming a shield on the left side of the push plate 602, and blocking the left end of the coverage range of the side plate 6 on the second electric conveyor belt 403, to prevent scrap iron from entering between the fourth electric push rod 601 and the push plate 602, which is beneficial to ensuring the stability of the device during actual use. When the drilling mechanism processes large pieces 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 transported on the second electric conveyor belt 403 can continue to enter the coverage range of the side plate 6, preparing for the planing and drilling processing 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 position 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 area of ​​the side plate 6 are pushed into the drilling mechanism for processing. Compared with directly connecting the drilling mechanism to the conveying direction of the right end of the second electric conveyor belt 403, the impact of the second electric conveyor belt 403 continuously conveying large pieces of scrap iron on the drilling mechanism when the drilling mechanism is running can be effectively reduced. At the same time, the feeding time of the drilling mechanism can also be greatly reduced. The process of large pieces of scrap iron entering the drilling mechanism is compressed into an instantaneous push of the push plate 602, which to a certain extent improves the efficiency of the device during processing.

[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, and conveys the scrap iron fragments to the lower hopper 301 through the first electric conveyor belt 401, and conveys the large pieces of scrap iron to the coverage range of the side plate 6 through the second electric conveyor belt 403. Then the fourth electric push rod 601 is powered on to drive the push plate 602 to move, and the large pieces of scrap iron in the coverage range of the side plate 6 are pushed onto the support plate 502 in the shell 501. After the third electric push rod 504 is powered on, it drives the support platform 505 to move downward, and the power unit in the support platform 505 drives the milling cutter 507 clamped in the clamping head 506 to rotate at a high speed. During the downward movement, the large pieces of scrap iron are cut and opened, forming a large number of evenly distributed through holes on the large pieces of scrap iron. After the cutting and drilling are completed, the third electric push rod 504 is powered on to drive the support platform 505 to move downward. The rod 504 retracts and drives the milling cutter 507 to move up and reset. The second electric push rod 503 pulls the support plate 502 to tilt downward, and the large pieces of scrap iron and metal chips after the hole is opened are dumped onto the first electric conveyor belt 401, and transported to the lower hopper 301. After weighing, they are quantitatively lowered 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 iron-making area 1 and docks with the iron-making mechanism 2. Then the furnace cover 203 covers the furnace body 103, and the electrode 205 is inserted into the furnace body 103. The electrode 205 is started to reduce and smelt the scrap iron in the furnace body 103. After the scrap iron smelting is completed, the iron-making mechanism 2 returns to its initial state, and the electric trolley 102 carries the furnace body 103 out of the iron-making area 1 for subsequent processing.

[0060] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
