Description

Technical Field

[0001] This invention relates to the field of waste metal processing technology, specifically to a waste metal recycling equipment for processing metal scrap and chips. Background Technology

[0002] The machining, equipment dismantling, and metal product manufacturing processes generate a large amount of metal waste and debris, including both relatively intact plates, scraps, block scraps, and long strips, as well as smaller metal particles and cutting chips. In existing scrap metal recycling processes, larger scraps typically require pre-treatment such as cutting and crushing to meet subsequent recycling requirements. Long or curled fragments require untangling and cutting, involving numerous processing steps. Further crushing, especially for thicker scraps and relatively intact plates, not only requires larger processing equipment and higher energy consumption but also risks over-fineening the originally highly intact metal waste.

[0003] In existing technologies, metal particles and debris that have been crushed or screened are typically densified by pressing, forming loose waste into block blanks for subsequent reprocessing. However, because different forms of scrap metal create pores of varying sizes during accumulation, simply pressing can cause larger blocks of scrap to bear the pressure first, while smaller particles do not flow sufficiently into the surrounding gaps, resulting in numerous pores within the formed body, affecting overall density and bonding. Furthermore, existing pressing methods struggle to ensure sufficient contact between long strips, plates, and thick angled pieces that are difficult to process further, making it challenging to achieve adequate contact with the smaller metal particles. On the other hand, when using heated pressing to improve metal plasticity, it is usually necessary to heat a large quantity of scrap material as a whole. This not only requires a long heating time but also consumes a lot of energy. Moreover, the high-temperature scrap material is prone to heat loss during transport, causing a temperature drop upon entering the forming area, making it difficult to fully utilize the plastic deformation effect at high temperatures. Summary of the Invention

[0004] The purpose of this invention is to provide a metal scrap and debris processing equipment for recycling waste metals, in order to solve the problems mentioned in the background art, such as the large number of pretreatment steps for difficult-to-process waste materials and the difficulty in fully filling and combining waste materials of different forms.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention directly arranges scrap metals such as long strips of waste, thicker corner pieces, and plates that are difficult to cut or crush further to form a skeleton, and uses replaceable support plates to separate and support the skeleton. During the filling process, vibration and preheating are used to fill the metal scraps in stages, so that small metal scraps can enter the gaps between the skeletons, thereby reducing the pre-processing steps of large scraps, while improving the filling degree between scrap metals of different shapes and the overall density after forming.

[0015] 2. This invention continuously heats a portion of fine metal scrap through a conveying heating tube, and temporarily stores the high-temperature material in an insulated box. At the same time, the residual heat is guided to preheat the metal scrap that is not directly heated. Then, the first and second compression plates compress the scrap in mutually perpendicular directions, allowing the high-temperature metal scrap to flow into the gaps in the skeleton under a high plasticity state and increasing the contact degree between different scrap metals. This reduces the amount of actively heated material used while improving the density and bonding effect of the formed scrap metal. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 This invention provides a technical solution: a waste metal recycling and scrap processing equipment, comprising a pressure frame 1, a first hydraulic rod 2 fixedly mounted on the pressure frame 1, a first compression plate 3 fixedly mounted on the telescopic rod of the first hydraulic rod 2, a second hydraulic rod 4 fixedly mounted on the pressure frame 1, a second compression plate 5 fixedly mounted on the telescopic rod of the second hydraulic rod 4, the second compression plate 5 being perpendicular to the first compression plate 3, and two sets of third hydraulic rods 7 fixedly mounted at one end of the pressure frame 1, the telescopic rods of the third hydraulic rods 7 extending... The same set of top plates 6 are fixedly installed on the compression rod. The top plates 6 are inserted into the left end of the pressure frame 1. The top plates 6, the second compression plate 5 and the first compression plate 3 are positioned opposite each other. A conveying heating pipe 8 is fixedly installed on the pressure frame 1. A heat preservation box 9 is provided at one end of the conveying heating pipe 8. The heat preservation box 9 is fixedly installed on the pressure frame 1. A feed hopper 10 is fixedly installed on one side of the heat preservation box 9. A discharge pipe 11 is movably inserted into the left end of the pressure frame 1. The discharge pipe 11 is connected to the heat preservation box 9. A support plate 12 is provided on the outside of the discharge pipe 11. The discharge mechanism 13 includes an induction heating ring 1304, a first corrugated pipe 1305, a vibration motor 1308, and a second corrugated pipe 1314. The induction heating ring 1304 is arranged in an array on the conveying heating pipe 8. The discharge pipe 11 is connected to the heat preservation box 9 through the first corrugated pipe 1305. Two sets of second corrugated pipes 1314 are arranged on the lower side of the feeding hopper 10. One end of the second corrugated pipe 1314 is arranged on the upper side of the discharge pipe 11. The vibration motor 1308 is installed on the upper side of the discharge pipe 11. The movable mechanism 14 includes a connecting bracket 1401 and a mounting frame 1405. Two sets of mounting frames 1405 are fixedly installed on the support plate 12. The connecting bracket 1401 is movably installed on the mounting frame 1405. The connecting bracket 1401 is engaged with the second compression plate 5. The pressure frame 1 provides the main space for arranging and forming scrap metal. The first compression plate 3 and the second compression plate 5 are driven by the first hydraulic rod 2 and the second hydraulic rod 4, respectively, and compress the scrap metal in the pressure area from mutually perpendicular directions. This causes the skeleton scrap to be constrained in multiple directions during the compression process, reducing the problem of long strip scrap, plate scrap and corner scrap moving outward. The conveying heating pipe 8 and the heat preservation box 9 are used to heat and temporarily store small metal scrap that needs to be improved in terms of plasticity. The discharge pipe 11 introduces the processed metal scrap into the pressure area. The support plate 12 supports and separates the manually arranged skeleton scrap, so that the skeleton is pre-formed with a filling space that is easy for particles to enter. At the same time, the support plate 12 can be gradually withdrawn during the movement of the discharge pipe 11, so that the space it occupies can be filled by the subsequently discharged metal scrap. This reduces the need for pre-treatment such as cutting and crushing of large pieces, long strips and thick corner scrap before forming, and improves the filling degree between different shapes of scrap and the final forming density.

[0020] Furthermore, the discharge mechanism 13 also includes a first rotary motor 1301, a screw conveyor 1302, and a feed connection flange 1303. The first rotary motor 1301 is fixedly mounted on the pressure frame 1, and the screw conveyor 1302 is rotatably mounted inside the conveying heating pipe 8. The output shaft of the first rotary motor 1301 is fixedly connected to the screw conveyor 1302. The feed connection flange 1303 is fixedly mounted on the conveying heating pipe 8 and is located on the side close to the first rotary motor 1301. The first rotary motor 1301 drives the screw conveyor 1302. The rotation allows the fine metal scrap to be continuously conveyed forward within the conveying heating tube 8. Simultaneously, the exchange of material positions during the spiral conveying process allows metal scrap at different locations to pass through the induction heating area in sequence. In conjunction with the induction heating ring 1304, the conveyed metal scrap is heated. This allows a small amount of fine metal scrap to quickly reach a state with high plasticity without the need for overall heating of large skeleton scrap. The spiral conveying allows heating and conveying to be carried out simultaneously, thereby reducing the amount of material that needs to be heated as a whole and providing conditions for subsequent gap filling and pressing using high-temperature metal scrap.

[0021] Furthermore, the discharge mechanism 13 also includes a right-angle tube 1306, a fixed platform 1307, a connecting ring 1309, a rubber strip 1310, an insertion slot 1311, an insertion plate 1312, and an insertion hole 1313. The right-angle tube 1306 is fixedly installed at the upper end of the discharge pipe 11. The two ends of the right-angle tube 1306 are respectively connected to the discharge pipe 11 and the first corrugated pipe 1305. The fixed platform 1307 is fixedly installed on the upper side of the right-angle tube 1306. The vibration motor 1308 is fixedly installed on the fixed platform 1307. The connecting ring 1309 is sleeved on the discharge pipe 11. The support plate 12 is fixed. Installed on the collar 1309, a rubber strip 1310 is fixedly installed on the outer side of the support plate 12. The rubber strip 1310 abuts against the inner wall of the pressure frame 1, the first compression plate 3, and the top plate 6. An insertion groove 1311 is opened on the upper side of the support plate 12. An insertion plate 1312 is fixedly installed on the upper side of the discharge pipe 11. The insertion plate 1312 is inserted into the insertion groove 1311. An insertion hole 1313 is opened on the insertion plate 1312. A screw is inserted into the insertion hole 1313. A threaded sleeve is fixedly installed in the insertion groove 1311, and the screw is installed in the threaded sleeve through the thread. Right angle tube 1 306 and the first corrugated pipe 1305 are used to keep the discharge pipe 11 connected to the insulation box 9. Simultaneously, the flexible deformation of the first corrugated pipe 1305 adapts to the positional changes of the discharge pipe 11 during vibration and lifting, ensuring that the insulation box 9 and the discharge pipe 11 do not lose connection due to relative movement. The vibration motor 1308 drives the discharge pipe 11 and the support plate 12 to vibrate via the fixed platform 1307, allowing the support plate 12 to vibrate and fill the scrap inside the skeleton, thereby promoting the entry of metal scrap into the gaps between the skeletons. The connecting ring 1309 is used to install the support plate 12... On the outside of the discharge pipe 11, the insertion plate 1312 is fitted with the insertion slot 1311 and fixed by a threaded structure, so that the support plate 12 can be disassembled and replaced according to the shape of different skeleton waste materials; the rubber strip 1310 is set on the outside of the support plate 12, and its own flexible deformation adapts to the swing and displacement of the support plate 12 during vibration, so that the support plate 12 can maintain a close fit with the edge of the pressure area when vibrating, avoiding excessive movement restriction of the support plate 12 due to rigid contact, thereby ensuring that the vibration of the support plate 12 can continuously act on the skeleton waste and the filler metal waste.

[0022] Furthermore, the discharge mechanism 13 also includes a collection box 1315 and a conical discharge port 1316. The collection box 1315 is fixedly installed at both ends of the fixed platform 1307. Two sets of conical discharge ports 1316 are provided at the lower end of the collection box 1315. The lower end of the second corrugated pipe 1314 is connected to the collection box 1315. The collection box 1315 is used to receive the preheated metal scrap conveyed by the second corrugated pipe 1314, and to concentrate and guide the material through the conical discharge ports 1316, so that the preheated metal scrap can be distributed accordingly. The different areas separated by the support plate 12 are discharged; since the distribution positions of the conical discharge port 1316 and the support plate 12 are corresponding, the preheated metal scrap can enter the skeleton more evenly, instead of being concentrated in a single position, thus preferentially filling the larger gaps in the skeleton, and preheating the skeleton in advance through the contact between the preheated particles and the skeleton; the second corrugated pipe 1314 uses its own flexibility to adapt to the vibration of the discharge pipe 11, so that the upstream feeding structure is not easily interfered with by the movement of the discharge pipe 11 during the continuous feeding process.

[0023] Furthermore, the discharge mechanism 13 also includes a mounting box 1317, a valve column 1318, a second rotary motor 1319, a discharge trough 1320, a flexible pad 1321, and a vibrating block 1322. The mounting box 1317 is fixedly installed on the lower side of the feed hopper 10. Two sets of second corrugated pipes 1314 are fixedly installed on the lower side of the mounting box 1317. The valve column 1318 is rotatably installed inside the mounting box 1317. The second rotary motor 1319 is fixedly installed at one end of the mounting box 1317. The output shaft of the second rotary motor 1319 is fixedly connected to the valve column 1318. The discharge trough 1320 is opened on the valve column 1318. The flexible pad 1321 is fixedly installed at one end of the valve column 1318. The vibrating block 1322 is fixedly installed on the flexible pad 1321. The valve column 1318 rotates to change the correspondence between the discharge trough 1320 and the lower channel of the feed hopper 10, thereby controlling the opening and closing of the feed hopper 10 and the discharge amount of preheated metal waste, so that the preheated particles can enter the pressure zone according to the filling requirements. When bridging or blockage occurs inside the feed hopper 10 due to the accumulation of fine metal waste, the second rotary motor 1319 increases the rotation state of the valve column 1318, causing the flexible pad 1321 and the vibrating block 1322 to oscillate, and apply the vibration force to the material inside the feed hopper 10, breaking the formed bridging and restoring the flow of the material. Thus, the same structure can simultaneously perform the functions of material discharge control and blockage treatment, improving the continuous feeding stability of preheated metal waste without setting up an additional independent unblocking mechanism.

[0024] Furthermore, the discharge mechanism 13 also includes a telescopic motor 1323, a guide block 1324, and a blocking column 1325. A guide block 1324 is fixedly installed on the lower inner side of the insulation box 9. A blocking column 1325 is movably inserted into the guide block 1324. The shape of the blocking column 1325 matches the shape of the guide block 1324, and the diameter of the blocking column 1325 matches the inner diameter of the first corrugated pipe 1305. A telescopic motor 1323 is fixedly installed on one side of the insulation box 9, and the output shaft of the telescopic motor 1323 is fixedly connected to the blocking column 1325. The guide block 1324 centrally guides the high-temperature metal waste inside the insulation box 9. The material continuously converges towards the area where the first corrugated pipe 1305 is located, reducing the disorderly accumulation of high-temperature particles inside the insulation box 9. The blocking column 1325 can extend into the end of the first corrugated pipe 1305, and by changing its insertion degree, the effective flow cross section of the first corrugated pipe 1305 can be adjusted, thereby controlling the discharge speed of the high-temperature metal waste and allowing the high-temperature particles to be fed according to the degree of skeleton filling. At the same time, when the blocking column 1325 moves back and forth, it can also destroy the local bridging formed at the discharge position, so that the metal waste whose flow state has changed after heating can still maintain a relatively stable discharge state, thus taking into account both flow regulation and anti-blocking functions.

[0025] Furthermore, the moving mechanism 14 also includes a roller 1402, a guide plate 1403, a positioning block 1404, a guide post 1406, a return spring 1407, a sliding block 1408, and a guide hole 1409. A roller 1402 is rotatably mounted on the upper side of the connecting bracket 1401. A guide plate 1403 is fixedly mounted on the upper end of the connecting bracket 1401. A positioning block 1404 is fixedly mounted on the upper side of the connecting bracket 1401. The distance between the roller 1402 and the positioning block 1404 is adapted to the thickness of the second compression plate 5. The lower side of the roller 1402 abuts against the upper side of the second compression plate 5. A guide post 1406 is fixedly mounted inside the mounting frame 1405. A return spring 1407 is sleeved on the guide post 1406. A sliding block 1408 is fixedly mounted on the lower end of the connecting bracket 1401. A guide hole 1409 is provided on the sliding block 1408, and the guide post 1406 is inserted into the guide hole. Inside 1409, the sliding block 1408 is slidably installed in the mounting frame 1405 via the guide post 1406, and the return spring 1407 abuts against the sliding block 1408; the connecting bracket 1401 is engaged with the edge of the second compression plate 5 via the roller 1402 and the positioning block 1404, so that when the second hydraulic rod 4 drives the second compression plate 5 to rise and fall, it can synchronously drive the discharge pipe 11 and the support plate 12 to move, thus eliminating the need for an additional independent lifting drive mechanism for the discharge pipe 11 and the support plate 12. When the second compression plate 5 descends and presses the guide plate 1403, the two sets of connecting brackets 1401 can open outward and compress the return spring 1407. After the edge of the second compression plate 5 enters between the roller 1402 and the positioning block 1404, the connecting bracket 1401 can automatically reset and complete the engagement; thus, the discharge pipe 11 and the support plate 12 can easily establish or disengage from the linkage with the second compression plate 5.

[0026] Furthermore, the moving mechanism 14 also includes a mounting groove 1410, a bearing wheel 1411, and a receiving belt 1412. The mounting groove 1410 is provided on the upper side of the pressure frame 1. The size of the mounting groove 1410 is adapted to the size of the support plate 12. The bearing wheel 1411 is rotatably mounted in an array within the mounting groove 1410, and the receiving belt 1412 is sleeved on the bearing wheel 1411. The first corrugated pipe 1305 and the second corrugated pipe 1314 are adapted to the size of the support plate 12. The mounting groove 1410 provides temporary storage space for the discharge pipe 11 and the support plate 12 after they exit the pressure area. The bearing wheel 1411 and the receiving belt 1412... The belt 1412 can receive the discharge pipe 11 and support plate 12 when they move to the mounting slot 1410, reducing friction and resistance during their movement. At the same time, some metal waste may still remain in the first corrugated pipe 1305 and the second corrugated pipe 1314 after the discharge is completed. When the discharge pipe 11 and support plate 12 move above the receiving belt 1412, the receiving belt 1412 can be used to shield and receive the lower side of the discharge pipe 11, preventing the residual particles from falling directly. It also makes it easier to bring the residual material back to the pressure area when the discharge pipe 11 is reset, thereby reducing material waste and improving the integrity of continuous operation of the equipment.

[0027] Furthermore, the active mechanism 14 also includes a heat-conducting pipe 1413 and an exhaust groove 1414. The heat-conducting pipe 1413 is fixedly installed on the upper end of the insulation box 9. The heat-conducting pipe 1413 is inserted into the feed hopper 10 and is located on the lower side of the feed hopper 10. An exhaust groove 1414 is opened on the lower side of the heat-conducting pipe 1413. The heat-conducting pipe 1413 guides the heat accumulated inside the insulation box 9 to the lower side of the feed hopper 10, and the hot air diffuses into the feed hopper 10 through the exhaust groove 1414. This utilizes the residual heat generated by the heated metal scrap to preheat another part of the fine metal scrap that has not been directly heated. In this way, before the high-temperature particles officially participate in the skeleton filling, the preheated particles can fill the larger space in the skeleton and preheat the skeleton, reducing the sudden drop in heat caused by direct contact between the high-temperature particles and the low-temperature skeleton. At the same time, it reduces the amount of metal scrap that needs to be actively heated by the induction heating ring 1304, so that the residual heat can be reused.

[0028] Working principle: In the embodiments of this invention, firstly, a support plate 12 suitable for the type, shape, and size of the scrap metal to be processed is selected. The support plate 12 is then fitted onto the sleeve ring 1309 on the outside of the discharge pipe 11, so that the insertion plate 1312 is inserted into the insertion slot 1311. Then, the insertion plate 1312 is fixed in the insertion slot 1311 by the cooperation of the screw and the screw sleeve, thereby completing the installation of the support plate 12. Subsequently, the discharge pipe 11 and the support plate 12 are inserted into the pressure area at the left end of the pressure frame 1, wherein the pressure area is formed by the pressure... The pressure frame 1, the first compression plate 3, and the top plate 6 are used to enclose the pressure area. The top plate 6 is used to open and close the pressure area. After the support plate 12 is installed, according to the shape of the support plate 12 and the internal space of the pressure area, long strips of waste, thicker corner pieces, plates with good integrity, and other scrap metals that are not easy to cut or crush are manually arranged around the support plate 12. This makes scrap metals of different shapes form a skeleton structure that is separated and supported by the support plate 12, thereby reducing the need for pre-treatment such as cutting and crushing of difficult-to-process waste.

[0029] Subsequently, the small metal scraps requiring active heating are fed into the conveying heating pipe 8 through the feed connection flange 1303. The first rotary motor 1301 drives the screw conveyor 1302 to rotate, causing the small metal scraps to be continuously conveyed along the conveying heating pipe 8. During the movement, the scraps pass through the induction heating ring 1304 in sequence, where they are heated to keep them solid and achieve a state with significantly improved plasticity. At the same time, the screw conveyor 1302 continuously tumbles the scraps as it moves, allowing scraps from different positions to alternately enter the heating area, thereby improving the uniformity of heating. After heating, the scraps continue to be conveyed forward by the screw conveyor 1302 and temporarily stored in the insulation box 9 to reduce heat loss after heating.

[0030] The heat generated by the high-temperature metal scrap inside the insulation box 9 accumulates upwards and is transferred to the lower side of the feed hopper 10 through the heat conduction pipe 1413, and then released into the feed hopper 10 through the exhaust groove 1414. This allows the small metal scraps in the feed hopper 10 that have not been actively heated to be preheated by the residual heat of the insulation box 9, thereby increasing the temperature of the unheated metal scraps when they enter the pressure zone. By using the residual heat to preheat the unheated metal scraps first, the amount of metal scraps that need to be directly induction heated can be reduced, and the temperature difference between the subsequently preheated metal scraps and the skeleton scraps can be reduced.

[0031] During filling, the second rotary motor 1319 is first controlled to drive the valve column 1318 to rotate, so that the discharge groove 1320 on the valve column 1318 corresponds to the discharge channel at the lower end of the feed hopper 10. The opening and closing degree of the feed hopper 10 and the discharge amount of preheated metal scrap are controlled by changing the rotation position of the valve column 1318. The preheated metal scrap enters the second corrugated pipe 1314 and enters the collection box 1315 along the second corrugated pipe 1314, and then is discharged downward through two sets of conical discharge ports 1316. Since the conical discharge ports 1316 correspond to the distribution position of the support plate 12, the preheated metal scrap can be fed more evenly into the skeleton area separated by the support plate 12, so that it can fill the larger gaps in the skeleton first, and the skeleton is preheated by the contact between the preheated metal scrap and the skeleton.

[0032] Subsequently, the high-temperature metal scrap heated by induction in the insulation box 9 is discharged. Under the action of the guide block 1324, the metal scrap in the insulation box 9 gathers at the location of the first corrugated pipe 1305. The telescopic motor 1323 drives the blocking column 1325 to move back and forth, so that the blocking column 1325 changes the opening degree of the end of the first corrugated pipe 1305, thereby controlling the discharge amount and discharge speed of the high-temperature metal scrap. The high-temperature metal scrap enters the pressure area through the first corrugated pipe 1305, the right-angle pipe 1306 and the discharge pipe 11 in sequence, and further fills the gaps that the preheated metal scrap could not fully fill, so that the high-temperature and highly plastic metal scrap enters the interior of the skeleton.

[0033] During the aforementioned material discharge process, the vibration motor 1308 drives the right-angle tube 1306, the discharge pipe 11, and the support plate 12 to vibrate via the fixed platform 1307. The first corrugated pipe 1305 and the second corrugated pipe 1314 allow the discharge pipe 11 to remain connected when vibrating relative to the insulation box 9. The vibration of the discharge pipe 11 is simultaneously transmitted to the support plate 12 and the surrounding pre-arranged skeleton waste, causing a slight positional adjustment of the long strips of waste, plates, and thicker corner pieces, changing the local gaps inside the skeleton, and making it easier for the metal waste to enter the skeleton under the action of vibration. At the same time, the vibration can promote the redistribution of the metal waste that has already entered the skeleton, reducing the local accumulation of particles and the formation of bridging.

[0034] When the discharge pipe 11 and support plate 12 need to be installed on the second compression plate 5, the second compression plate 5 is moved downward. The lower edge of the second compression plate 5 first contacts and presses the guide plate 1403 on the upper side of the connecting bracket 1401, causing the two sets of connecting brackets 1401 to move outward respectively, and compressing the return spring 1407 through the sliding block 1408. When the edge of the second compression plate 5 moves between the roller 1402 and the positioning block 1404, the second compression plate 5 no longer applies an outward pushing force to the guide plate 1403. The connecting bracket 1401 returns to its original position under the elastic action of the return spring 1407, so that the roller 1402 and the positioning block 1404 are located on the upper and lower sides of the second compression plate 5 respectively, thereby locking the second compression plate 5 between the roller 1402 and the positioning block 1404, so that the second hydraulic rod 4 can subsequently drive the second compression plate 5, the connecting bracket 1401, the discharge pipe 11 and the support plate 12 to move up and down simultaneously.

[0035] During the material discharge and vibration filling process, the second hydraulic rod 4 drives the second compression plate 5 to rise and fall, thereby driving the discharge pipe 11 and the support plate 12 to rise and fall stably. Therefore, during filling, the discharge pipe 11 and the support plate 12 can be moved along the inside of the pressure area by the second hydraulic rod 4, so that the support plate 12 can be gradually pulled upward from the inside of the frame. During the movement, the discharge pipe 11 continuously discharges metal scrap, so that the space released after the support plate 12 is pulled away can be filled by preheated metal scrap and high-temperature metal scrap in time. This forms a dynamic filling process of vibration, material discharge and pull-away of support plate 12 at the same time, so that the metal scrap is pre-distributed in different areas inside the frame before final compression.

[0036] When the support plate 12 is nearly completely withdrawn from the pressure frame 1, the rollers 1402 on the connecting bracket 1401 can roll at the corresponding position on the pressure frame 1, causing the connecting bracket 1401 to move adaptively relative to the second compression plate 5, thereby allowing the discharge pipe 11 and the support plate 12 to continue withdrawing and eventually move to the mounting groove 1410 position on the upper side of the pressure frame 1; the bearing wheel 1411 and the receiving belt 1412 in the mounting groove 1410 receive the discharge pipe 11 and the support plate 12, so that the lower end of the discharge pipe 11 can be blocked by the receiving belt 1412; when it is needed for reuse, the discharge pipe 11 and the support plate 12 can move back towards the pressure area along the bearing wheel 1411 and the receiving belt 1412.

[0037] During the feeding process of the feeding hopper 10, if the metal scrap forms a bridge or becomes blocked inside the feeding hopper 10, the rotation of the valve column 1318 can be accelerated by the second rotary motor 1319, causing the flexible pad 1321 and the vibrating block 1322 at the end of the valve column 1318 to oscillate, and the vibration force is applied to the feeding hopper 10 and the metal scrap inside, thereby breaking the bridge formed between the materials and allowing the materials to resume feeding. At the same time, the degree of rotation of the valve column 1318 is used to adjust the correspondence between the discharge trough 1320 and the lower channel of the feeding hopper 10, thereby controlling the discharge speed of the preheated metal scrap. The high-temperature metal scrap in the insulation box 9 is controlled by the reciprocating movement of the blocking column 1325 by the telescopic motor 1323, which adjusts the opening of the first corrugated pipe 1305, and when the material accumulates locally, the reciprocating action of the blocking column 1325 breaks the local bridge, so that the high-temperature metal scrap can maintain a relatively stable discharge state.

[0038] After the preheated and high-temperature metal scraps have filled the internal space of the frame, the second compression plate 5 is moved to a predetermined position by the second hydraulic rod 4, so that it continues to compress the scrap metal in the pressure area. At the same time, the first hydraulic rod 2 drives the first compression plate 3 to move into the pressure area, so that the first compression plate 3 and the second compression plate 5 squeeze the frame scrap and the filling scrap inside from mutually perpendicular directions. This causes the long strips of scrap, plates and thicker corner pieces to be laterally constrained during the compression process, reducing the outward movement of the frame. At the same time, it causes the preheated and high-temperature metal scraps to move further into the remaining pores inside the frame. After the first compression plate 3 and the second compression plate 5 have completed the compression, the top plate 6 moves to the left end of the pressure frame 1 and closes the pressure area, thereby forming a closed state for the temporary storage and retention of subsequent molding materials.

[0039] Subsequently, the first hydraulic rod 2 and the second hydraulic rod 4 continue to drive the first compression plate 3 and the second compression plate 5 for compression. Under the combined action of the first compression plate 3 and the second compression plate 5, the high-temperature metal scrap undergoes plastic deformation under pressure and flows into the spaces between long scrap, plate and thicker corner pieces that are not yet fully filled. This allows the fine metal scrap to further fill the internal pores of the skeleton and increases the actual contact area between scrap metals of different shapes. After continuous compression and pressure holding, the skeleton scrap and the filling scrap form a recycled metal billet with a high degree of density and integrity.

[0040] After molding is completed, the top plate 6 is moved upward to open the pressure area on the left end of the pressure frame 1. Then, the first compression plate 3 is driven forward by the first hydraulic rod 2 to push the molded recycled metal blank out of the pressure area. After the molded blank is discharged, the first compression plate 3 is reset and the second hydraulic rod 4 and the movable mechanism 14 are readjusted so that the discharge pipe 11 and the support plate 12 re-enter the pressure area to prepare for the next arrangement and filling of the scrap metal skeleton.
